Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, a communication device, and a computer-readable storage medium. Background Art

[0002] Beamforming is a signal processing technique that uses an antenna array to transmit and receive signals in a directionally controlled manner. In beamforming, signals are sent in a specific direction rather than omnidirectionally. This beam-based signal transmission method focuses signal power in a specific direction, increasing the likelihood of signal detection at the destination or improving signal reception quality.

[0003] To ensure communication quality, existing protocols incorporate a beam management mechanism to select high-quality beams for communication. In this existing beam management mechanism, the network device configures or triggers the terminal device to submit a beam report. The terminal device then performs beam measurements based on the network device's configuration and sends the beam report to the network device. The network device then performs beam management or beam switching based on the received beam report. Furthermore, because beam-based communication is prone to signal interruption due to factors such as obstruction, existing protocols also incorporate a beam failure recovery (BFR) mechanism to address signal interruptions.

[0004] The existing beam management process and BFR process are independent of each other. If the network device is configured with both beam management parameters and BFR parameters, the terminal device must execute both the beam management process and the BFR process. Summary of the Invention

[0005] One of the technical objectives of the present application is to provide a communication method, a communication device, and a computer-readable storage medium that can optimize the existing beam management process and BFR process.

[0006] In a first aspect, an embodiment of the present application provides a communication method, the method comprising: receiving configuration information, the configuration information comprising parameters for a first process and / or a second process, the first process comprising: a beam management process and / or a beam switching process, the second process comprising: a beam failure recovery BFR process and / or a radio link monitoring RLM process; wherein, the first trigger condition is related to the second process, and / or the second trigger condition is related to the first process; the first trigger condition comprises: a first start condition and / or a first stop condition, the first start condition is used to trigger the start of the first process, and the first stop condition is used to trigger the stop of the first process; the second trigger condition comprises: a second start condition and / or a second stop condition, the second start condition is used to trigger the start of the second process, and the second stop condition is used to trigger the stop of the second process.

[0007] In the above scheme, the first start condition is used to trigger the start of the first process, and the first start condition is related to the second process. With such a scheme, the network device or terminal device can determine whether the first start condition is met based on the execution status of the second process in the second process, and start the first process if the first start condition is met. Since the first process is a beam management process and / or a beam switching process, and the second process is a BFR process and / or an RLM process, the started first process can assist and supplement the second process. For example, if the second process does not detect a beam failure, the first process can promptly identify the deterioration of the channel quality of the terminal device, thereby enabling timely beam management or beam switching. Therefore, the above scheme can promptly identify different degrees of communication link abnormalities.

[0008] In the above solution, the second start condition is used to trigger the start of the second process, and the second start condition is related to the first process. Using this solution, the network device or terminal device can determine whether the start condition of the second process is met based on the execution status of the first process during the first process, and start the second process if the second start condition is met. Because the first process is a beam management process and / or a beam switching process, and the second process is a BFR process and / or an RLM process, the activated second process can assist and supplement the first process to promptly identify signal interruptions such as beam failure or radio link failure, thereby promptly restoring communication between the terminal device and the network device. Therefore, the above solution can promptly identify communication link abnormalities of varying degrees.

[0009] In the above scheme, the first stop condition is used to trigger the stopping of the first process, and the first stop condition is related to the second process. With such a scheme, the network device or the terminal device can determine whether the first stop condition is satisfied in the second process based on the execution status of the second process, and stop the first process if the first stop condition is satisfied. In the case where the signal interruption has been identified through the second process, there is no need to detect the deterioration of the channel quality of the terminal device through the first process, or, in the case where the signal has been restored through the second process, there is no need to search for a new beam through the first process. Therefore, the above scheme utilizes the similarity or substitutability of the steps or functions in the first process and the second process to simplify the process to be executed by the terminal device. The terminal device does not need to continue to execute the first process, which is conducive to reducing the power consumption of the terminal device.

[0010] In the above solution, the second stop condition is used to trigger the termination of the second process, and the second stop condition is related to the first process. With this solution, the network device or terminal device can determine whether the second stop condition is met based on the execution status of the first process during the first process, and terminate the second process if the second stop condition is met. The network device or terminal device can terminate the second process if the first process detects deteriorating channel quality or identifies a new beam. The first process maintains communication quality between the terminal device and the network device, eliminating the need for the terminal device to continue executing the second process, thus saving power consumption.

[0097] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, long term evolution (LTE) systems, fifth generation (5G) systems (such as new radio (NR) systems), and future evolution systems or multiple communication convergence systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The solutions of the embodiments of the present application can also be applicable to new communication systems in the future, for example, a sixth generation (6G) communication system, a seventh generation (7G) communication system, and the like.

[0098] This application mainly relates to the communication between terminal devices (or simply referred to as terminals) and network devices.

[0099] The terminal equipment (Terminal Equipment) in the embodiments of the present application may refer to various forms of user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal equipment (Terminal Equipment), wireless communication equipment, user agent or user device. The terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited to this. In some embodiments of the present application, the terminal device may be an electronic device with a data wireless transmission function. In other embodiments of the present application, the terminal device may also be a device with a transceiver function, such as a chip system. The chip system may include chips and other discrete devices.

[0100] The network device in the embodiment of the present application can also be called an access network device, for example, it can be a base station (BS) (also called base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in the second-generation (2G) network, the device providing the base station function includes a base transceiver station (BTS), the device providing the base station function in the 3G network includes a node B (NodeB), and the device providing the base station function in the 4G network includes an evolved node B (eNB). In wireless local area networks (WLAN), the device providing the base station function is an access point (AP), and the device providing the base station function in NR is the next generation node base station (gNB), and the evolved node B (ng-eNB), wherein the gNB and the terminal communicate using NR technology, and the ng-eNB and the terminal communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network device in the embodiment of the present application also includes a device that provides base station functions in a future new communication system. In some embodiments, the network device may also be a device that provides wireless communication functionality for the terminal device, such as a chip system. For example, the chip system may include a chip and may also include other discrete devices.

[0101] In a downlink beam management or downlink beam switching scheme, the network device configures or triggers the terminal device to report a beam report. The terminal device performs beam measurement and reports a beam report based on the reporting period configured by the network device and / or the trigger instruction sent by the network device. The beam report includes quality information of one or more beams. The network device obtains the channel quality based on the beam report. When the network device identifies that the channel quality is poor, the network device instructs the terminal device to switch to a new beam or activate a new beam.

[0102] Specifically, in the above-mentioned uplink beam management or uplink beam switching scheme, the network device configures or triggers the terminal device to send a sounding reference signal (SRS), and the terminal device sends the SRS based on the sending period configured by the network device and / or the trigger instruction sent by the network device. The network device measures the SRS and determines the channel state of the terminal device based on the measurement result of the SRS. When the network device identifies that the channel quality is poor, the network device instructs the terminal device to switch to a new beam or activate a new beam.

[0103] It can be seen that this beam management or beam switching scheme is initiated by the network device, and the terminal device only passively sends beam reports or SRS based on the configuration or triggering of the network device to assist the network device in determining the current beam quality. If the channel quality of the terminal device deteriorates, but the network device has not configured the terminal device to report beam reports or send SRS at this time, the network device cannot be informed of the deterioration of channel quality in a timely manner, resulting in untimely beam switching, affecting the communication quality of the terminal device. If the network device obtains timely channel quality changes through frequent configuration or trigger signaling, it will increase the measurement and reporting overhead, as well as the reference signal and channel resource occupancy overhead.

[0104] Furthermore, the beam management process and the BFR process are independent of each other. If the network device is configured with both beam management and BFR parameters, the terminal device must perform both the beam management and BFR processes. Because some steps or functions of these two processes are similar, executing both processes independently by the terminal device will increase power consumption.

[0105] In view of this, in the solution of the embodiment of the present application, the network device configures parameters for the first process and / or the second process for the terminal device. The first process includes: a beam management process and / or a beam switching process, and the second process includes: a beam failure recovery BFR process and / or a radio link monitoring RLM process. The first trigger condition is related to the second process, and / or the second trigger condition is related to the first process; the first trigger condition includes: a first start condition and / or a first stop condition, the first start condition is used to trigger the start of the first process, and the first stop condition is used to trigger the stop of the first process; the second trigger condition includes: a second start condition and / or a second stop condition, the second start condition is used to trigger the start of the second process, and the second stop condition is used to trigger the stop of the second process.

[0106] In the above scheme, the first start condition is used to trigger the start of the first process, and the first start condition is related to the second process. With such a scheme, the network device or terminal device can determine whether the first start condition is met based on the execution status of the second process in the second process, and start the first process if the first start condition is met. Since the first process is a beam management process and / or a beam switching process, and the second process is a BFR process and / or an RLM process, the started first process can assist and supplement the second process. For example, if the second process does not detect a beam failure, the first process can promptly identify the deterioration of the channel quality of the terminal device, thereby enabling timely beam management or beam switching. Therefore, the above scheme can promptly identify different degrees of communication link abnormalities.

[0107] In the above solution, the second start condition is used to trigger the start of the second process, and the second start condition is related to the first process. Using this solution, the network device or terminal device can determine whether the start condition of the second process is met based on the execution status of the first process during the first process, and start the second process if the second start condition is met. Because the first process is a beam management process and / or a beam switching process, and the second process is a BFR process and / or an RLM process, the activated second process can assist and supplement the first process to promptly identify signal interruptions such as beam failure or radio link failure, thereby promptly restoring communication between the terminal device and the network device. Therefore, the above solution can promptly identify communication link abnormalities of varying degrees.

[0108] In the above solution, the first stop condition is used to trigger the termination of the first process, and the first stop condition is related to the second process. Using this solution, the network device or terminal device can determine whether the first stop condition is met based on the execution status of the second process during the second process, and terminate the first process if the first stop condition is met. If a signal interruption has been identified through the second process, there is no need to detect deterioration in the terminal device's channel quality through the first process. Alternatively, if the signal has been restored through the second process, there is no need to search for a new beam through the first process. Therefore, the above solution utilizes the similarity or substitutability of steps or functions between the first and second processes to simplify the processes to be performed by the terminal device, thereby reducing the power consumption of the terminal device.

[0109] In the above solution, the second stop condition is used to trigger the termination of the second process, and the second stop condition is related to the first process. With this solution, the network device or terminal device can determine whether the second stop condition is met based on the execution status of the first process during the first process, and terminate the second process if the second stop condition is met. The network device or terminal device can terminate the second process if the first process detects deteriorating channel quality or identifies a new beam. The first process maintains communication quality between the terminal device and the network device, eliminating the need for the terminal device to continue executing the second process, thus saving power consumption.

[0110] First, some of the terms involved in the embodiments of the present application are introduced to facilitate understanding by those skilled in the art.

[0111] 1. Beam

[0112] A beam is a communication resource through which network devices and terminal devices can send and receive signals. The beam in the embodiments of the present application can be a wide beam, a narrow beam, or other types of beams.

[0113] In communication protocols, beams can be expressed as spatial relations, spatial domain filters, spatial filters, spatial parameters, spatial domain parameters, Transmission Configuration Indication (TCI) states, Quasi Co-Location (QCL) parameters, etc. This article uses the term "beam" for this purpose, but "beam" can be replaced with other equivalent concepts and is not limited to the concepts mentioned above.

[0114] 2. Beam information

[0115] In the embodiments of the present application, "beam information" may refer to information that can be used to determine or indicate a beam. For example, the beam information may include any of the following: beam identification information, spatial relationship information, spatial filter information, spatial filter information, spatial parameter information, TCI status information, QCL information, etc.

[0116] In a specific implementation, the identification information of the beam may be a reference signal resource indicator or a reference signal resource index (index), wherein the reference signal may be a channel state information reference signal (CSI-RS), and accordingly, the reference signal resource indicator may be a CSI-RS resource indicator (CRI). Alternatively, the reference signal may be a synchronization signal block (SSB), and accordingly, the reference signal resource indicator may be an SSB resource indicator (SSB RI). The reference signal resource index may be a CSI-RS resource index or an SSB resource index.

[0117] In this article, beam information is also referred to as "beam information".

[0118] For example, downlink beam information can be generally represented by TCI status information or QCL information, and uplink beam information can be generally represented by TCI status information or spatial relationship information.

[0119] 3. Cell

[0120] In communication protocols, a cell can be expressed as a carrier, component carrier (CC), subband, frequency band, bandwidth, frequency point, physical cell, serving cell, transmission and receiving point (TRP), etc. This document uses the term "cell", but "cell" and the above equivalent concepts are interchangeable. "Cell" can be replaced by other equivalent concepts, such as the concepts listed above, but is not limited to them.

[0121] Furthermore, the cell information in the embodiments of the present application may include at least one of the following: cell index, cell identifier, physical cell identifier (PCI), identification information of RS resource configuration associated with the cell, identification information of RS resource set associated with the cell, identification information of RS resources associated with the cell, identification information of report configuration associated with the cell, and TRP identifier.

[0122] The TRP may be at least one of the following: control resource set, control resource set pool, control resource set group, terminal capability set, terminal capability, TCI state, TCI state pool, terminal capability value, terminal capability value set, reference signal resource, reference signal resource set, reference signal resource group, number of reference signal ports, antenna panel, antenna array, antenna subarray, antenna group, antenna subgroup, antenna set, antenna subset, serving cell, physical cell. The TRP may be uniquely identified by one or more of the identifiers of at least one of the above items.

[0123] 4. BFR Process

[0124] The BFR process in the embodiment of the present application may include the following steps A, B, C, and D:

[0125] Step A: The terminal device detects a beam failure event.

[0126] Specifically, in step A, the terminal device measures the Beam Failure Detection Reference Signal (BFDRS) at the physical layer, and determines whether a beam failure event occurs based on the measurement results. The conditions for the terminal device to determine whether a beam failure event occurs include: if the measurement results of all BFDRS are lower than the measurement threshold value, the terminal device determines that a beam failure instance (BFI) is detected, and the physical layer of the terminal device can report a BFI indication to the Media Access Control (MAC) layer. The MAC layer uses a counter to count the BFI indications reported by the physical layer. Whenever a BFI indication is received, the BFI timer is restarted. When the BFI timer times out, the BFI counter is reset to zero and restarts. When the BFI counter reaches the maximum number of times configured by the network device, the terminal device declares that a beam failure event has occurred.

[0127] It should be noted that the “measurement results” in this article may include at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference & Noise Ratio (SINR), Signal-to-noise ratio (SNR), Channel Quality Indicator (CQI), Received Signal Strength Indication (RSSI), etc.

[0128] Step B: The terminal device identifies the new beam.

[0129] Specifically, in step B, the terminal device measures the New Beam Identification Reference Signal (NBIRS) at the physical layer to find a new beam. When the physical layer of the terminal device receives a request from the MAC layer to notify the physical layer to perform new beam identification, the physical layer of the terminal device measures each NBIRS resource and then reports the NBIRS resource identifier whose measurement result exceeds the measurement threshold to the MAC layer. The MAC layer selects a beam from the beams corresponding to the NBIRS resource identifier reported by the physical layer as the new beam. For example, the MAC layer may select the beam with the best measurement result as the new beam.

[0130] It should be noted that the embodiment of the present application does not limit the execution order of step A and step B. Step B can be executed before step A, or step B can be executed after step A, or step A and step B can be executed simultaneously.

[0131] It should also be noted that step A and step B are performed before step C.

[0132] Step C: The terminal device sends a beam failure recovery request (BFRQ) to the network device.

[0133] Specifically, the terminal device can inform the network device of a beam failure event through BFRQ. More specifically, the terminal device can inform the network device of the failed beam and / or the identified new beam through BFRQ. For the primary cell BFR process, BFRQ is the PRACH resource, and for the secondary cell BFR process, BFRQ is the BFRMACCE.

[0134] Step D: The network device sends a beam failure recovery response (BFRR) to the terminal device.

[0135] Specifically, after sending the BFRQ, the terminal device can monitor the response of the network device to the BFRQ. For the primary cell BFR process, after the network device receives the BFRQ, it can send a BFRR on the dedicated physical downlink control channel (PDCCH) on the configured BFR control resource set (CORESET-BFR). For the secondary cell BFR process, after the network device receives the BFRQ, it can send a PDCCH as a BFRR. The DCI carried by this PDCCH uses the same HARQ process number as the PUSCH where the BFRMACCE is located and uses a flipped new data indication (tolledNDI) to schedule a PUSCH. More specifically, BFRR may include at least one of the following: cell radio network temporary identifier (Cell-RadioNetworkTemporaryIdentifier, C-RNTI), indication information for switching to a new beam, indication information for restarting beam search, etc. Furthermore, if the terminal device monitors the BFRR, the terminal device may consider that the BFR process is successfully completed. If the terminal device does not detect BFRR, the terminal device may consider that the BFR process is unsuccessful. In this case, the physical layer of the terminal device may send an indication of the failure of the BFR process to the higher layer of the terminal device.

[0136] In a specific implementation, the terminal device may perform BFR on multiple cells. For example, the terminal device may perform BFR on a primary cell and at least one secondary cell respectively.

[0137] 5. Radio Link Monitoring (RLM) Process

[0138] In the solution of the embodiment of the present application, the RLM process may include the following steps i and ii.

[0139] Step i: Detect a Radio Link Failure (RLF) event.

[0140] Specifically, the network device can configure the reference signal (RLM-Reference Signal, RLM-RS) resources for the RLM process, and the physical layer of the terminal device can monitor the downlink radio link quality of the primary cell (Primary Cell, PCell) and the primary secondary cell (Primary Secondary CellP, SCell) based on the reference signal in the configured RLM-RS resources. In a specific implementation, the terminal device can perform the RLM process within the scope of the activated downlink bandwidth part (BandwidthPart, BWP). Among them, the RLM-RS resources may include synchronization reference signal (Synchronization SignalBlock, SSB) resources and / or CSI-RS resources.

[0141] Furthermore, the terminal device can compare the measurement results on the RLM-RS resources (that is, the downlink radio link quality of the RLM-RS resources) with the configured measurement threshold. The two measurement threshold values ​​in the RLM process are Qout and Qin. If the measurement results on all RLM-RS resources are less than Qout, the physical layer of the terminal device can report an out of sync indication to the radio resource control (RRC) layer. As long as the measurement result on one of the configured RLM-RS resources is better than Qin, the physical layer of the terminal device can report an in sync indication to the RRC layer.

[0142] Furthermore, the network device is also configured with a timer and a counter for the RLM process. Specifically, the counters for the RLM process may include: counter N310 and counter N311. N310 may be used to count out-of-sync indications received by the RRC layer, and N311 may be used to count in-sync indications received by the RRC layer. The timer for the RLM process may include counter T310.

[0143] Specifically, if the RRC layer receives N310 consecutive out-of-sync indications from the physical layer, T310 starts. Subsequently, if the RRC layer receives N311 consecutive in-sync indications from the physical layer, T310 stops, and the terminal device considers the radio link to be normal and can start a new round of RLM. If T310 times out, the terminal device determines that an RLF event has been detected.

[0144] Step ii. RRC connection reestablishment.

[0145] In one example, after the terminal device declares RLF, the terminal device may send radio link failure information to the network device, so that the network device can send a cell handover indication to the terminal device, and the terminal device can perform cell handover to restore the radio link. The terminal device declaring RLF may mean that the terminal device determines that an RLF event is detected. Restoring the radio link may mean restoring the RRC connection between the terminal device and the network device.

[0146] In another example, after the terminal device declares RLF, the terminal device may send an RRC reestablishment request. Further, the network device may send an RRC reestablishment response to the terminal device. The RRC reestablishment request may be an RRC reestablishment (RRCreestablishment) message or an RRC setup (RRCsetup) message. For example, the network device may send an RRC reestablishment (RRCreestablishment) message or an RRC setup (RRCsetup) message to the terminal device, and the terminal device reports an RRC reestablishment completion message or an RRC setup completion message to the network after the RRC connection is restored. Alternatively, the network device may send an RRC connection release indication to the terminal device, and the terminal device may enter an idle state or an inactive state based on the RRC connection release indication.

[0147] In another example, after a terminal device declares RLF, it may initiate random access to re-access the network. For example, the terminal device may initiate random access in the current serving cell, such as by initiating random access in the current serving cell based on RRC reestablishment information. In another example, the terminal device may initiate random access in a new cell. In another example, the terminal device may measure the SSB and send a random access channel to complete cell selection or cell access.

[0148] For more information about RLM, RLF detection and RRC connection reestablishment, please refer to the relevant description of the existing protocol, which will not be repeated here.

[0149] 6. The first process

[0150] In an embodiment of the present application, the first process may include: a beam management process and / or a beam switching process. Exemplarily, the first process may refer to an existing beam management process, or may be an existing beam switching process.

[0151] In another embodiment of the present application, the first process refers to a beam management process actively triggered by a terminal device. Alternatively, the first process refers to a beam management process passively triggered by a terminal device. Among them, the "beam management process passively triggered by a terminal device" can be understood as the network device sending an instruction to trigger a beam report to the terminal device or the network device configuring a reporting period for a beam report, and the terminal device starts beam management based on the instruction to trigger a beam report sent by the network device or the reporting period for the configured beam report. The "beam management process actively triggered by a terminal device" can be understood as the terminal device does not rely on the instruction to trigger a beam report sent by the network device or the reporting period for the configured beam report to start beam management, but starts beam management based on the detection result of the first event.

[0152] Alternatively, the first process refers to a beam switching process actively triggered by the terminal device. Alternatively, the first process may be a beam switching process passively triggered by the terminal device. Among them, the "beam switching process passively triggered by the terminal device" can be understood as the network device sending an instruction to trigger beam switching to the terminal device, and the terminal device starts the beam switching process based on the instruction to trigger beam switching sent by the network device. The "beam switching process actively triggered by the terminal device" can be understood as the terminal device does not rely on the instruction to trigger beam switching sent by the network device to start beam switching, but starts beam switching based on the detection result of the first event.

[0153] The "active trigger" in this article can also be understood as "active initiation".

[0154] Specifically, the first process may include at least one of steps a to e:

[0155] Step a: The terminal device detects a first event. The first event may be defined by a protocol, or may be configured by a network device.

[0156] The "first event" in this article can also be described or replaced by "event", "beam switching event", "beam management event", "beam event", "switching event", "event of the first process", etc. This article does not limit the name of the "first event".

[0157] In the scheme of the embodiment of the present application, the "first event" can be used for beam management or beam switching. Specifically, the first event can be an event that can characterize at least one of the following: the beam quality of the current beam deteriorates, the beam quality of the alternative beam is better than the beam quality of the current beam, or the beam quality of the alternative beam is improved. More specifically, the first event can be at least one of the following events: the beam quality of the current beam deteriorates, the beam quality of the alternative beam is improved, the beam quality of the alternative beam is better than the beam quality of the current beam, the beam interference of the current beam increases, the beam interference of the alternative beam decreases, the beam interference of the alternative beam is less than the beam interference of the current beam, the beam quality of the current cell deteriorates, the beam quality of the alternative cell is improved, the beam quality of the alternative cell is better than the beam quality of the current cell, the beam interference of the current cell increases, the beam interference of the alternative cell decreases, the beam interference of the alternative cell is less than the beam interference of the current cell, etc., but is not limited to this.

[0158] For more details about the first event, please refer to the relevant description of Example 1 below, which will not be repeated here.

[0159] Step b: The terminal device sends the first information to the network device. Correspondingly, the network device receives the first information. The first information can be used to notify the network device to execute the first process. That is, the first information can be used to notify the network device to execute the steps required of the network device in the first process. It should be noted that the present embodiment of the application does not limit the name of "first information."

[0160] Specifically, after detecting the first event, the terminal device can send a first information to the network device so that the network device can be informed of the channel changes of the terminal device. In particular, the network device can be informed of the deterioration of the channel quality of the terminal device based on the first information, so that beam management or beam switching can be performed in a timely manner.

[0161] More specifically, the first information may include at least one of the following: information about a detected first event, information indicating a failed beam, information indicating a failed cell, information indicating a new beam, and information indicating a new cell. The specific meanings of "failed beam," "failed cell," "new beam," and "new cell" can be found in the relevant description below and are not detailed here.

[0162] In the above solution, by reporting failed beams and / or new beams to the network device, the network device can promptly learn of beams and / or new beams with deteriorating quality within the current beams, thereby enabling targeted switching of the deteriorating beams. By reporting failed cells and / or new cells to the network device, the need for further cell switching during beam switching or beam management can be met when multiple cells are capable of providing beams to the terminal device.

[0163] In one example, the request information includes information about a detected switching event and / or indication information of a failed beam, but the request information does not include indication information of a new beam or the request information includes indication information that a new beam was not detected. In this case, the network device may perform step c. Alternatively, the network device may update the first RS resource configured for the terminal device for new beam detection.

[0164] In a specific implementation, step c may be performed after step b, or step d may be performed after step b. Alternatively, after step b, the terminal device may perform step e.

[0165] Step c: The network device instructs or configures at least one of the following to the terminal device: beam measurement, beam reporting, beam training, and beam switching.

[0166] In one example, after receiving the first information, the network device may configure or instruct the terminal device to perform beam measurement according to the request information.

[0167] In another example, after receiving the first information, the network device may configure or instruct the terminal device to report a beam report. The beam report may be a beam report defined by an existing protocol, which is not limited in this embodiment.

[0168] In yet another example, after receiving the first information, the network device may configure the terminal device to initiate a beam training process.

[0169] In another example, the network device may indicate a new beam to the terminal device based on the first information, so that the terminal device switches to the new beam. For example, the network device may send an indication signaling to the terminal device, where the indication signaling is used to indicate the beam to be switched to. Furthermore, after receiving the indication signaling, the terminal device may send a response to the indication signaling and / or switch to the new beam indicated by the network device. The beam indicated by the indication signaling may be one or more new beams indicated in the first information, or may be a new beam not indicated in the first information.

[0170] By adopting such a solution, the network device no longer needs to configure the terminal device to report the beam report, but directly indicates the target beam based on the first information triggered by the switching event, which is conducive to reducing the delay of beam switching.

[0171] It can be seen from the above that the first information in the first process can be used to trigger beam management and / or beam switching.

[0172] Specifically, the beam management in the embodiments of the present application may be intra-cell beam management. Alternatively, the beam management in the embodiments of the present application may be inter-cell beam management. Intra-cell beam management may refer to determining, for one or more failed beams, a new beam in the cell where the failed beams are located. Inter-cell beam management may refer to determining, for one or more failed beams, a new beam in a cell other than the cell where the failed beams are located.

[0173] Specifically, the beam switching in the embodiment of the present application may include: beam switching within a cell, and / or beam switching between cells. Among them, beam switching within a cell may mean: the beam before switching and the beam after switching belong to the same cell. In other words, beam switching within a cell may mean: switching from an invalid beam to a new beam, the cell to which the new beam belongs is the same as the cell to which the invalid beam belongs. Beam switching between cells may mean: the beam before switching and the beam after switching belong to different cells. In other words, beam switching between cells may mean: switching from an invalid beam to a new beam, the cell to which the new beam belongs is different from the cell to which the invalid beam belongs. Further, beam switching between cells may also include: switching from a current cell to a new cell, the new cell being different from the current cell. Among them, the current cell here is the current serving cell.

[0174] Furthermore, after step c, the terminal device may execute step e. Specifically, after step c, the terminal device may skip step d and directly execute step e. Alternatively, after step c, the terminal device may first execute step d and then execute step e.

[0175] Step d: The network device sends a second message to the terminal device. Correspondingly, the terminal device receives the second message. The second message is used to confirm that the network device has received the first message.

[0176] Specifically, after receiving the first information, the network device may send second information to the terminal device. Exemplarily, the second information may be carried in the DCI. In a specific implementation, the second information may be used to confirm beam switching and / or cell switching, or the second information may be used to trigger beam switching and / or cell switching.

[0177] For example, the first information may include information about the new beam, and the second information may indicate the new beam. The new beam indicated by the second information may be selected from the new beam indicated by the first information. After receiving the second information, the terminal device may switch to the new beam indicated by the second information. In this case, the second information implicitly or indirectly indicates that the network device has received the first information.

[0178] Alternatively, the first information may not include information about the new beam. For example, the first information may include information about the detected first event and / or information about the failed beam, and the second information may include information about the new beam. After receiving the second information, the terminal device may switch to the new beam indicated by the second information. Alternatively, the first information indicates a new beam, and the second information also indicates a new beam. After receiving the second information, the terminal device may switch to the new beam indicated by the first information or the second information. The new beam indicated by the second information may be the same as or different from the new beam indicated by the first information.

[0179] As another example, the second information may be used to confirm or trigger the terminal device to switch to the new cell indicated by the first information. For example, the first information may include cell information of the new cell to indicate the new cell, and the second information may include cell confirmation information. After receiving the second information, the terminal device may switch to the new cell indicated by the first information.

[0180] Alternatively, the first information may not indicate a new cell, and the second information may indicate a new cell. For example, the new cell may be the cell to which the new beam indicated by the second information belongs. After receiving the second information, the terminal device may switch to the new cell indicated by the second information. Alternatively, the first information indicates a new cell, and the second information also indicates a new cell. After receiving the second information, the terminal device may switch to the new cell indicated by the first information or the second information. The new cell indicated by the second information may be the same as or different from the new cell indicated by the first information.

[0181] Further, after step d, the terminal device may execute step e.

[0182] Step e: The terminal device performs beam switching.

[0183] Specifically, the terminal device may perform beam switching to switch to a new beam. As described above, beam switching may be intra-cell beam switching. Specifically, the terminal device may switch from a failed beam to a corresponding new beam. In this case, both the failed beam and the new beam are new beams on the serving cell.

[0184] Alternatively, beam switching may be inter-cell beam switching. That is, the terminal device performs not only beam switching but also cell switching. Specifically, the terminal device not only switches from the failed beam to the corresponding new beam, but also switches from the serving cell where the failed beam is located to the cell where the new beam is located. The cell where the new beam is located may be a neighboring cell of the serving cell or a candidate cell, etc., and this is not limited in the embodiments of the present application.

[0185] 7. Current beam

[0186] In the embodiment of the present application, the current beam refers to the beam currently being used by the terminal device. The number of current beams may be one, or the number of current beams may be multiple.

[0187] In a specific implementation, each cell may provide one or more beams. The current beam may be the beam of the serving cell of the terminal device, or the beam of a cell other than the serving cell. For example, the current beam may be the beam of a neighboring cell of the serving cell.

[0188] Exemplarily, there are multiple current beams, where some of the current beams are beams of the serving cell, and the other beams are beams of other cells outside the serving cell.

[0189] As another example, the number of current beams is one or more, wherein the current beams are all beams of the serving cell.

[0190] It should be noted that, when the current beam includes beams of other cells other than the serving cell, the terminal device uses the beams provided by other cells but does not access or switch to other cells.

[0191] 8. Current cell

[0192] In the embodiment of the present application, the current cell refers to the cell to which the current beam belongs. In other words, the current cell refers to the cell that provides the current beam.

[0193] Specifically, the current cell may include a serving cell and / or a non-serving cell. In a carrier aggregation (CA) scenario, the serving cell may include a primary cell and at least one secondary cell, and the current beam may include the current beam of the primary cell and the current beam of each secondary cell. A non-serving cell refers to a cell other than the serving cell. For example, the current cell may include a neighboring cell. That is, the terminal device only uses the beam of the neighboring cell to transmit a channel or signal, but the neighboring cell is not the serving cell of the terminal device, that is, the neighboring cell is a non-serving cell.

[0194] 9. Alternative beams

[0195] The "alternative beam" in the embodiments of the present application refers to the beam configured by the network device.

[0196] More specifically, the "alternative beam" may refer to a beam configured by the network device and not currently used by the terminal device. Alternatively, the "alternative beam" may refer to a beam available for measurement or selection by the terminal device.

[0197] The “alternative beam” may also be described as a candidate beam, a measurable beam, a configured beam, a selectable beam, etc. The name of the alternative beam is not limited herein.

[0198] In a specific implementation, the network device may configure association relationships between beams, where one beam may be associated with another beam, or one beam may be associated with multiple beams, or multiple beams may be associated with multiple beams, or multiple beams may be associated with one beam.

[0199] Specifically, the association between beams can be determined based on the association between RS resources used to measure beams. In one example, the RS resource used to measure beam 10 is RS resource 10, and the RS resource used to measure beam 20 is RS resource 20. RS resource 10 is associated with RS resource 1, RS resource 2, RS resource 3, and RS resource 4, and RS resource 20 is associated with RS resource 5, RS resource 6, RS resource 7, and RS resource 8. Assuming that RS resource 1 is used to measure beam 1, RS resource 2 is used to measure beam 2, RS resource 3 is used to measure beam 3, RS resource 4 is used to measure beam 4, RS resource 5 is used to measure beam 5, RS resource 6 is used to measure beam 6, RS resource 7 is used to measure beam 7, and RS resource 8 is used to measure beam 8, it can be determined that beam 10 is associated with beam 1, beam 2, beam 3, and beam 4, and beam 20 is associated with beam 5, beam 6, beam 7, and beam 8.

[0200] More specifically, a current beam can be associated with one or more candidate beams. Alternatively, multiple current beams can be associated with multiple candidate beams. Alternatively, multiple current beams can be associated with the same candidate beam.

[0201] Exemplarily, if a current beam is determined to be the beam to be switched, the alternative beam associated with the current beam may be used as the new beam, or the corresponding new beam may be determined or detected from the alternative beams associated with the current beam.

[0202] In the embodiments of the present application, the candidate beams may include candidate beams for a first process and candidate beams for a second process. The candidate beams for the first process and the second process may be the same or different. The second process may include a BFR process and / or a RLM process. For example, the candidate beams in the BFR process may be beams corresponding to NBIRS resources.

[0203] 10. Alternative Residential Areas

[0204] In the embodiments of the present application, a "candidate cell" may refer to a cell to which a candidate beam belongs. The number of candidate cells may be one or more. The candidate cell and the current cell may be different cells. The candidate cell may be a candidate cell configured by a network device. For example, the candidate cell may be a neighboring cell of the current cell. For another example, the PCI of the candidate cell may be different from the PCI of the serving cell. The "candidate cell" herein may also be referred to as a "candidate cell."

[0205] Exemplarily, an association relationship may exist between the candidate cell and the current cell. For example, the network device may configure a candidate cell group (or candidate cell list) for the current cell, and the candidate cells in the candidate cell group are associated with the current cell. For a current cell, the first event detection and / or new beam detection may be performed on the candidate cell associated with the current cell.

[0206] 11. Failed beam

[0207] In the embodiments of the present application, a failed beam may refer to a beam in the current beam that satisfies the first event. In other words, a failed beam refers to a current beam whose beam quality has deteriorated. A "failed beam" may also be referred to as a beam that needs to be switched, a beam about to become ineffective, a beam to be switched, an unavailable beam, or a beam whose beam quality has continuously deteriorated. This document does not limit the name of a failed beam.

[0208] Exemplarily, if the first information includes information about a failed beam, it may indicate that the beam quality of the current beam of the terminal device has deteriorated, and the terminal device requests or suggests beam switching.

[0209] Specifically, the disabled beam in this article may include: a disabled beam in a serving cell and / or a disabled beam in a non-serving cell (such as a disabled beam in a candidate cell).

[0210] It should be noted that, in this article, “information of a failed beam” may refer to beam information of a failed beam.

[0211] 12. Failed Cell

[0212] In the solution of the embodiment of the present application, the outage cell may refer to a cell that needs to be switched. In a specific implementation, the outage cell may be a serving cell to which the outage beam belongs. Alternatively, the outage cell may refer to a serving cell that satisfies the first event. Exemplarily, the outage cell may include a primary cell and / or a secondary cell. Exemplarily, if the first information includes information about the outage cell, it may indicate that the channel quality of the current serving cell of the terminal device has deteriorated, and the terminal device requests or suggests a cell switch. For the specific content of the first information, please refer to the relevant description of the first information above, which will not be repeated here.

[0213] 13. New Beam

[0214] The “new beam” in the embodiment of the present application can be understood as a beam that can be switched to.

[0215] In a specific implementation, the new beam may include a new beam in the serving cell and / or a new beam in a non-serving cell (such as a candidate cell). That is, the new beam and the current beam may belong to the same cell or different cells, which is not limited in this embodiment.

[0216] The terminal device may determine a new beam in the first process. Alternatively, the terminal device may determine a new beam in the second process. For ease of distinction, this document refers to the new beam determined in the first process as the "first new beam," and the new beam determined in the second process as the "second new beam." Specifically, the first new beam may refer to a beam among the alternative beams that satisfies the first event. In other words, the first new beam may refer to a beam whose beam quality has improved. The "first new beam" may also be referred to as: a recommended beam, a recommended new beam, an available beam, a beam whose beam quality continues to improve, etc., and this document does not limit the name of the first new beam. The second new beam may be a new beam determined by step B in the BFR process. The "second new beam" may also be referred to as: a new candidate beam, etc., and this document does not limit the name of the second new beam.

[0217] It should be noted that, in this article, “information of the new beam” may refer to beam information of the new beam.

[0218] 14. New Community

[0219] In the embodiments of the present application, a new cell refers to a cell that a terminal device recommends switching to, a cell that the terminal device is about to switch to, or a cell that a network device instructs to switch to. In a specific implementation, the new cell may be the cell to which the new beam belongs. The new cell may include a primary cell and / or a secondary cell.

[0220] The terminal device may determine a new cell or switch to a new cell in the first process. Alternatively, the terminal device may determine a new cell or switch to a new cell in the second process. For ease of distinction, the new cell determined or switched to in the first process is referred to herein as the "first new cell," and the new cell determined or switched to in the second process is referred to herein as the "second new cell."

[0221] Exemplarily, the first new cell may be a cell among the candidate cells that satisfies the first event, or may be a cell to which the first new beam belongs. In a specific implementation, the first information may include cell information of the first new cell to indicate that the terminal device recommends switching to the first new cell.

[0222] Exemplarily, the second new cell may refer to a cell to which the second new beam belongs. In one example, after the terminal device detects a beam failure event and identifies the second new beam, if the second new beam and the current beam belong to a different cell, the terminal device may further perform cell switching to switch to the cell to which the second new beam belongs.

[0223] As another example, the second new cell may be a new cell determined by the terminal device when performing cell selection after detecting RLF, or a new cell to which the terminal device switches when performing cell switching.

[0224] It should be noted that, in this document, “information of the new cell” may refer to identification information of the new cell, for example, PCI of the new cell, etc., but is not limited thereto.

[0225] 15. Beam quality

[0226] In the solution of the embodiment of the present application, the beam quality can be characterized by a measurement result obtained by measuring the RS resource. The measurement result can be at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference & Noise Ratio (SINR), Signal-to-noise ratio (SNR), Channel Quality Indicator (CQI), Received Signal Strength Indication (RSSI), etc. In a specific implementation, the measurement result used to characterize the beam quality can be configured by the network device or defined by the protocol.

[0227] 16. Beam Interference

[0228] In the embodiments of the present application, beam interference refers to interference between one beam and another beam. A terminal device can perform measurements on interference measurement resources (IMRs) to obtain beam interference. IMRs are RS resources dedicated to interference measurement.

[0229] In a specific implementation, for a beam, the beam interference of the beam can be obtained based on the IMR measurement on the cell to which the beam belongs, or can be obtained based on the IMR measurement on cells other than the cell to which the beam belongs. Assuming that Beam 1 is provided by Cell 1, the terminal device can measure the non-zero-power IMR on Cell 1 to obtain the local beam interference of Beam 1 or measure the zero-power IMR on Cell 1 to obtain the neighboring cell interference of Beam 1. Alternatively, the terminal device can measure the IMR on Cell 2 to obtain the neighboring cell beam interference of Beam 1.

[0230] The following is a detailed description of the specific embodiments of the present application in conjunction with the accompanying drawings. In the following embodiments, the actions performed by the network device can be performed by the network device, a device in the network device (such as a processor, chip), a chip, etc., and the actions performed by the terminal device can be performed by the terminal device, a device in the terminal device (such as a processor, chip), a chip, etc., and this application does not limit them. For the convenience of description, the embodiments provided in this application are described using the execution subjects as network devices and terminal devices as examples.

[0231] Example 1

[0232] Reference Figure 1 , Figure 1 This is a signaling interaction diagram of the first communication method in the embodiment of the present application. Figure 1 The communication method shown may include S11. In this application, S in each step number represents a step.

[0233] S11, the network device sends configuration information to the terminal device, where the configuration information includes parameters for the first process and / or the second process. Correspondingly, the terminal device receives the configuration information.

[0234] In one possible implementation, S11 may be replaced with: the network device sends first configuration information and second configuration information to the terminal device, where the first configuration information is used to configure the first process, and the second configuration information is used to configure the second process. In other words, the first configuration information includes parameters for the first process, and the second configuration information includes parameters for the second process.

[0235] The parameters used for the first process can be understood or described as parameters required for the first process, and the parameters used for the second process can be understood or described as parameters required for the second process.

[0236] It should be noted that this embodiment does not limit the order in which the network device sends the first configuration information and the second configuration information. The network device may configure the first process first and then the second process. That is, the network device first sends the first configuration information and then the second configuration information. Alternatively, the network device may configure the second process first and then the first process. That is, the network device first sends the second configuration information and then the first configuration information. Alternatively, the first configuration information and the second configuration information may be carried in the same signaling, that is, the network device may configure the first process and the second process simultaneously. It should be noted that the signaling in this document may be at least one of RRC layer signaling, MAC layer signaling, and physical layer signaling. In one example, the network device may send the first configuration information, and the first configuration information may include the second configuration information. In another example, the network device may send the second configuration information, and the second configuration information may include the first configuration information.

[0237] Furthermore, the first configuration information may be associated with the second configuration information. The association between the first configuration information and the second configuration information may refer to the association between the parameters used for the first process and the parameters used for the second process. Specifically, the manner in which the first configuration information and the second configuration information are associated includes but is not limited to the following:

[0238] Method 1: The network device sends first configuration information to the terminal device, where the first configuration information includes the second configuration information. In response, the terminal device receives the first configuration information. Since the first configuration information includes the second configuration information, the terminal device can determine that the first configuration information is associated with the second configuration information.

[0239] Method 2: The network device sends second configuration information to the terminal device, where the second configuration information includes the first configuration information. In response, the terminal device receives the second configuration information. Since the second configuration information includes the first configuration information, the terminal device can determine that the first configuration information is associated with the second configuration information.

[0240] Method 3: The network device sends first configuration information and second configuration information to the terminal device, where the first configuration information includes an identifier of the second configuration information and / or the second configuration information includes an identifier of the first configuration information. Accordingly, the terminal device receives the first configuration information and the second configuration information. Because the first configuration information includes the identifier of the second configuration information and / or the second configuration information includes the identifier of the first configuration information, the terminal device can determine that the first configuration information is associated with the second configuration information.

[0241] Method 4: The network device sends the first configuration information and the second configuration information to the terminal device. Furthermore, the network device indicates the association between the first configuration information and the second configuration information via signaling. In response, the terminal device receives the first configuration information and the second configuration information and determines, based on the signaling, that the first configuration information is associated with the second configuration information.

[0242] Method 5: The network device sends the first configuration information and the second configuration information to the terminal device. In addition, the network device enables the association between the first configuration information and the second configuration information through enabling information. Correspondingly, the terminal device receives the first configuration information and the second configuration information, and determines the association between the first configuration information and the second configuration information based on the enabling information. The enabling information can be carried in the same signaling as the first configuration information and / or the second configuration information, or the enabling information can be carried in different signaling than the first configuration information and / or the second configuration information.

[0243] It should be noted that, in other embodiments, the first configuration information may not be associated with the second configuration information.

[0244] In a specific implementation, the parameters used for the first process may include at least one of the following: configuration of the first event, configuration of reference signal resources, configuration of uplink transmission resources, configuration of a counter, configuration of a timer, or configuration of a measurement threshold.

[0245] The parameters used in the first process are described in detail below.

[0246] 1. Configuration of the first event

[0247] Specifically, the configuration of the first event may include: identification information of the first event, conditions included in the first event, and a measurement threshold corresponding to the first event. The identification information of the first event can be used to uniquely identify the handover event; that is, the identification information of different handover events is different. The term "identification" herein can also be replaced with "index."

[0248] In a specific implementation, the first event may be defined by a protocol, or may be configured by a network device. It should be noted that this document does not limit the name of the first event. The first event may include at least one of conditions (1) to (16). When the measurement result satisfies the conditions included in the first event, the terminal device determines that the first event has occurred.

[0249] Condition (1): The beam quality of the current beam is less than or equal to the first threshold value.

[0250] Assume that the number of current beams is X. The X current beams may be beams provided by different cells or beams provided by the same cell.

[0251] Exemplarily, condition (1) may mean that the beam qualities of at least X' current beams among the X current beams are less than or equal to the first threshold. That is, X' is a positive integer, X'≤X. In one example, X'=X. That is, condition (1) may mean that the beam qualities of the X current beams are all less than or equal to the first threshold.

[0252] As another example, condition (1) may mean that the beam quality of any current beam among the X current beams is less than or equal to the first threshold value.

[0253] Condition (2): The beam quality of the candidate beam is greater than or equal to the second threshold value.

[0254] Assume that the number of candidate beams is Y. The Y candidate beams may be beams provided by different cells or beams provided by the same cell.

[0255] Exemplarily, condition (2) may mean that the beam qualities of at least Y' of the Y candidate beams are greater than or equal to the second threshold. That is, Y' is a positive integer, and Y' ≤ Y. In one example, Y' = Y. That is, condition (2) may mean that the beam qualities of all Y candidate beams are greater than or equal to the second threshold.

[0256] As another example, condition (2) may mean that the beam quality of any one of the Y candidate beams is greater than or equal to the second threshold value.

[0257] Condition (3): The beam quality of the candidate beam is greater than or equal to the beam quality of the current beam.

[0258] In one possible implementation, the current beam in condition (3) may be a beam that satisfies condition (1), and / or the candidate beam in condition (3) may be a candidate beam that satisfies condition (2).

[0259] Exemplarily, condition (3) may mean that the beam quality of the alternative beam is greater than or equal to the beam quality of at least X” current beams. X” is a positive integer, X”≤X. That is, the beam quality of the X” current beams is compared with the beam quality of an alternative beam respectively. If the beam quality of the alternative beam is greater than or equal to the beam quality of the X” current beams, then the alternative beam and the X” current beams meet condition (3). In one example, X”=X. That is, condition (3) may mean that the beam quality of the alternative beam is greater than or equal to the beam quality of all current beams.

[0260] Exemplarily, condition (3) may mean that the beam quality of the candidate beam is greater than or equal to the beam quality of any current beam. That is, for any current beam, the beam quality of the current beam is compared with the beam quality of an candidate beam. If the beam quality of the candidate beam is greater than or equal to the beam quality of the current beam, then the candidate beam and the current beam meet condition (3).

[0261] Condition (4): The beam quality of the candidate beam is greater than or equal to the beam quality of the current beam, and the difference between the beam quality of the candidate beam and the beam quality of the current beam is greater than or equal to a third threshold value.

[0262] Among them, the current beam in condition (4) can be the current beam that meets condition (1), and / or, the alternative beam in condition (4) can be the alternative beam that meets condition (2), and the embodiments of the present application are not limited to this.

[0263] Exemplarily, condition (4) may mean that the beam quality of the alternative beam satisfies: the beam quality of the alternative beam is greater than or equal to the beam quality of each beam in at least X” current beams, and the difference between the beam quality of the alternative beam and the beam quality of each beam in the X” current beams is greater than or equal to a third threshold value. That is, the beam qualities of the X” current beams are compared with the beam quality of an alternative beam respectively. If the beam quality of the alternative beam is greater than or equal to the beam quality of the X” current beams, and the difference between the beam quality of the alternative beam and the beam quality of each current beam is greater than or equal to the third threshold value, then the alternative beam and the X” current beams satisfy condition (4).

[0264] Exemplarily, condition (4) may mean that the beam quality of the candidate beam is greater than or equal to the beam quality of any current beam, and the difference between the beam quality of the candidate beam and the beam quality of the current beam is greater than or equal to a third threshold. That is, for any current beam, the beam quality of the current beam is compared with the beam quality of an candidate beam. If the beam quality of the candidate beam is greater than or equal to the beam quality of the current beam, and the difference between the two is greater than or equal to the third threshold, then the candidate beam and the current beam meet condition (4).

[0265] Condition (5): The beam interference of the current beam is greater than or equal to the fourth threshold value.

[0266] In a possible implementation, the current beam in condition (5) may be a beam that satisfies at least one of conditions (1), (3), and (4).

[0267] Assume that the number of current beams is X. The X current beams may be beams provided by different cells or beams provided by the same cell.

[0268] Exemplarily, condition (5) may mean that the beam interference of at least X'' current beams among the X current beams is greater than or equal to the fourth threshold. That is, X'' is a positive integer, X'' ≤ X. In one example, X'' = X. That is, condition (5) may mean that the beam interference of the X current beams is greater than or equal to the fourth threshold.

[0269] As another example, condition (5) may mean that the beam interference of any current beam among the X current beams is greater than or equal to a fourth threshold value.

[0270] Condition (6): The beam interference of the candidate beam is less than or equal to the fifth threshold.

[0271] In a possible implementation, the candidate beam in condition (6) may be a beam that satisfies at least one of conditions (2) to (4).

[0272] Assume that the number of candidate beams is Y. The Y candidate beams may be beams provided by different cells or beams provided by the same cell.

[0273] Exemplarily, condition (6) may mean that the beam interference of at least Y” of the Y alternative beams is less than or equal to the fifth threshold value. That is, Y” is a positive integer, Y”≤Y. In one example, Y”=Y. That is, condition (6) may mean that the beam interference of the Y” alternative beams is less than or equal to the second threshold value.

[0274] As another example, condition (6) may mean that the beam interference of any one of the Y candidate beams is less than or equal to the fifth threshold value.

[0275] Condition (7): The beam interference of the candidate beam is less than or equal to the beam interference of the current beam.

[0276] In one possible implementation, the current beam in condition (7) may be a current beam that satisfies at least one of conditions (1), (3), (4) and (5), and / or the alternative beam in condition (7) may be an alternative beam that satisfies at least one of conditions (2) to (4) and (6). This embodiment of the present application is not limited to this.

[0277] Exemplarily, condition (7) may mean that the beam interference of the alternative beam is less than or equal to the beam qualities of at least X"" current beams. X"" is a positive integer, X""≤X. In one example, X""=X. In other words, the beam interference of X"" current beams is compared with the beam interference of an alternative beam respectively. If the beam interference of the alternative beam is less than or equal to the beam interference of X"" current beams, then the alternative beam and the X"" current beams meet condition (7).

[0278] Exemplarily, condition (7) may mean that the beam interference of the candidate beam is less than or equal to the beam interference of any current beam. That is, for any current beam, the beam interference of the current beam is compared with the beam interference of an candidate beam. If the beam interference of the candidate beam is less than or equal to the beam interference of the current beam, then the candidate beam and the current beam meet condition (7).

[0279] Condition (8): The beam interference of the candidate beam is less than or equal to the beam interference of the current beam, and the difference between the beam interference of the current beam and the beam interference of the candidate beam is greater than or equal to a sixth threshold value.

[0280] In one possible implementation, the current beam in condition (8) may be a current beam that satisfies at least one of conditions (1), (3), (4) and (5), and / or the alternative beam in condition (7) may be an alternative beam that satisfies at least one of conditions (2) to (4) and (6).

[0281] Exemplarily, condition (8) may mean that the beam interference of the alternative beam satisfies: the beam interference of the alternative beam is less than or equal to the beam interference of each beam in at least X"" current beams, and the difference between the beam interference of each beam in at least X"" current beams and the beam quality of the alternative beam is greater than or equal to the sixth threshold value. That is, the beam interferences of the X"" current beams are compared with the beam interference of an alternative beam respectively. If the beam interference of the alternative beam is less than or equal to the beam interference of the X"" current beams, and the difference between the beam interference of each current beam and the beam interference of the alternative beam is greater than or equal to the sixth threshold value, then the alternative beam and the X"" current beams satisfy condition (8).

[0282] As another example, condition (8) may mean that the alternative beam satisfies: the beam interference of the alternative beam is less than or equal to the beam interference of any current beam, and the difference between the beam interference of the current beam and the beam interference of the alternative beam is greater than or equal to a sixth threshold value. That is, for any current beam, the beam interference of the current beam is compared with the beam interference of an alternative beam. If the beam interference of the alternative beam is less than or equal to the beam interference of the current beam, and the difference between the beam interference of the current beam and the beam interference of the alternative beam is greater than or equal to the sixth threshold value, then the alternative beam and the current beam satisfy condition (8).

[0283] It should be noted that X, Y, X', X", X"', X"", Y' and Y" in this document are all positive integers, and the values ​​of one or more of X, Y, X', X", X"', X"", Y' and Y" can be configured by the network device or defined by the protocol.

[0284] Condition (9): The beam quality of the current cell is less than or equal to the seventh threshold.

[0285] Specifically, the beam quality of the cell in this article can be obtained by measuring the RS resources configured by the network device in the cell for the first process.

[0286] In one possible implementation, the beam quality of the current cell may be a first result obtained based on the beam quality of at least one current beam in the current cell. That is, for a current cell, the beam quality of the current cell may be determined based on the beam quality of at least one current beam in the current cell. In this case, if the beam quality of the current cell satisfies condition (9), it can be considered that all current beams in the current cell satisfy condition (9), or that the current beam used to determine the first result satisfies condition (9). Assuming that cell 1 is the current cell, if the first result of cell 1 is less than or equal to the seventh threshold value, cell 1 satisfies condition (9). Conversely, if the first result of cell 1 is greater than the seventh threshold value, cell 1 does not satisfy condition (9).

[0287] Assuming that M beams in a current cell are current beams, where M is a positive integer, the first result is exemplarily described below with reference to a specific example.

[0288] Example 1: The first result is the beam quality of the beam with the best or worst beam quality among the M current beams.

[0289] Example 2: The first result is the average value of the beam qualities of M current beams.

[0290] Example 3: The first result is the average value of the beam qualities of the M' beams with the best or worst beam qualities among the M current beams, where M' is a positive integer greater than 1, and M'≤M.

[0291] Example 4: The first result is the average value of the beam qualities of the beams in the M current beams whose beam qualities are greater than or equal to the eighth threshold value, or the first result is the average value of the beam qualities of the beams in the M current beams whose beam qualities are less than or equal to the eighth threshold value.

[0292] In another possible implementation, the beam quality of the current cell may refer to the beam quality of each current beam in the M current beams of the current cell. Specifically, for a current cell, if the beam qualities of all current beams in the current cell are less than or equal to the seventh threshold value, then the current cell satisfies condition (9). Conversely, if the beam quality of any current beam in the current cell is greater than the seventh threshold value, then the current cell does not satisfy condition (9). In this implementation, if the beam quality of a current cell satisfies condition (9), it can be regarded that all current beams in the current cell satisfy condition (9).

[0293] In another possible implementation, the beam quality of the current cell may refer to the beam quality of K beams among the M current beams of the current cell. Wherein, K is a positive integer, and K≤M. Wherein, the value of K may be configured by a network device, or may be defined by a protocol. Specifically, for a current cell, if the beam quality of K beams among all the current beams in the current cell is less than or equal to the seventh threshold value, then the current cell satisfies condition (9). Conversely, if the number of beams among all the current beams in the current cell whose beam quality is less than or equal to the seventh threshold value is less than K, then the current cell does not satisfy condition (9).

[0294] Condition (10): The beam quality of the candidate cell is greater than or equal to the ninth threshold value.

[0295] In one possible implementation, the beam quality of the alternative cell may be a second result obtained based on the beam quality of at least one alternative beam in the alternative cell. That is, for an alternative cell, the beam quality of the alternative cell may be determined based on the beam quality of at least one alternative beam in the alternative cell. In this case, if the beam quality of the alternative cell satisfies condition (10), it can be considered that all alternative beams in the alternative cell satisfy condition (10), or that the alternative beams used to determine the second result satisfy condition (10). Assuming that cell 2 is an alternative cell, if the second result of cell 2 is greater than or equal to the ninth threshold value, cell 2 satisfies condition (10). Conversely, if the second result of cell 2 is less than the ninth threshold value, cell 2 does not satisfy condition (10).

[0296] Assuming that N beams in a candidate cell are candidate beams, where N is a positive integer, the second result is exemplarily described below with reference to a specific example.

[0297] Example 5: The second result is the beam quality of the beam with the best or worst beam quality among the N candidate beams.

[0298] Example 6: The second result is the average value of the beam qualities of the N candidate beams.

[0299] Example 7: The second result is the average value of the beam qualities of N' beams with the best or worst beam qualities among the N candidate beams, where N' is a positive integer greater than 1, and N'≤N.

[0300] Example 8: The second result is the average value of the beam qualities of the beams whose beam qualities are greater than or equal to the tenth threshold value among the N alternative beams, or the second result is the average value of the beam qualities of the beams whose beam qualities are less than or equal to the tenth threshold value among the N alternative beams.

[0301] In another possible implementation, the beam quality of the alternative cell may refer to the beam quality of each alternative beam in the N alternative beams of the alternative cell. Specifically, for an alternative cell, if the beam qualities of all alternative beams in the alternative cell are greater than or equal to the ninth threshold value, the alternative cell satisfies condition (10). Conversely, if the beam quality of any alternative beam in the alternative cell is less than the ninth threshold value, the alternative cell does not satisfy condition (10). In this implementation, if the beam quality of an alternative cell satisfies condition (10), it can be regarded as that all alternative beams in the alternative cell satisfy condition (10).

[0302] In another possible implementation, the beam quality of the alternative cell may refer to the beam quality of K' beams among the N alternative beams of the alternative cell. K' is a positive integer, and K'≤N. The value of K' may be configured by a network device, or may be defined by a protocol. Specifically, for an alternative cell, if the beam quality of K' beams among all the alternative beams in the alternative cell is greater than or equal to the ninth threshold value, the alternative cell satisfies condition (10). Conversely, if the number of beams among all the alternative beams in the alternative cell whose beam quality is greater than or equal to the ninth threshold value is less than K', the alternative cell does not satisfy condition (10).

[0303] Condition (11): The beam quality of the candidate cell is greater than or equal to the beam quality of the current cell.

[0304] In one possible implementation, the beam quality of the current cell may be a first result obtained based on the beam quality of at least one current beam of the current cell, and the beam quality of the alternative cell may be a second result obtained based on the beam quality of at least one alternative beam of the alternative cell. In this case, condition (11) may also be understood as: the second result of the alternative cell is greater than or equal to the first result of the current cell. If the beam quality of a current cell satisfies condition (11) and the beam quality of an alternative cell satisfies condition (11), it can be considered that all current beams in the current cell satisfy condition (11), or the current beam in the cell used to determine the first result satisfies condition (11), and the current beam in the alternative cell satisfies condition (11), or the alternative beam in the alternative cell used to determine the second result satisfies condition (11). For the specific contents of the first result and the second result, please refer to the relevant description above.

[0305] Assume that cell 1 is the current cell and cell 2 is the candidate cell, the M beams in cell 1 are the current beams and the N beams in cell 2 are the candidate beams. If the second result obtained from the beam quality of the N candidate beams of cell 2 is greater than or equal to the first result obtained from the beam quality of the M current beams of cell 1, then cell 1 meets condition (11) and cell 2 meets condition (11). Conversely, if the second result obtained from the beam quality of the N candidate beams of cell 2 is less than the first result obtained from the beam quality of the M current beams of cell 1, then cell 1 and cell 2 do not meet condition (11).

[0306] In another possible implementation, the beam quality of the current cell refers to the beam quality of at least one current beam in the current cell, and the beam quality of the candidate cell refers to the beam quality of at least one candidate beam in the candidate cell.

[0307] Specifically, assuming that M beams in a current cell are current beams and N beams in a candidate cell are candidate beams, condition (11) can be understood as follows, but is not limited to the following understanding:

[0308] In an example, condition (11) can be understood as: the beam quality of each of the N candidate beams in the candidate cell is greater than or equal to the beam quality of all current beams in the current cell.

[0309] In another example, condition (11) can be understood as: the beam quality of at least N" beams among the N alternative beams in the alternative cell is greater than or equal to the beam quality of all current beams in the current cell. Wherein, N" is a positive integer, and N"≤N.

[0310] In another example, condition (11) can be understood as follows: for each current beam in the current cell, there is at least one alternative beam in the candidate cell whose beam quality is greater than the beam quality of the current beam. In other words, condition (11) can be understood as follows: the alternative beams of the candidate cell include: at least one alternative beam corresponding to each current beam in the current cell, wherein the beam quality of the at least one alternative beam corresponding to each current beam is greater than or equal to the beam quality of the current beam. The at least one alternative beam corresponding to different current beams can be the same or different.

[0311] Condition (12): The beam quality of the candidate cell is greater than or equal to the beam quality of the current cell, and the difference between the beam quality of the candidate cell and the beam quality of the current cell is greater than or equal to the eleventh threshold value.

[0312] In one possible implementation, the beam quality of the current cell may be a first result obtained based on the beam quality of at least one current beam of the current cell, and the beam quality of the alternative cell may be a second result obtained based on the beam quality of at least one alternative beam of the alternative cell. In this case, condition (12) may also be understood as: the difference obtained by subtracting the first result of the current cell from the second result of the alternative cell is greater than or equal to the eleventh threshold value. If the beam quality of a current cell satisfies condition (12) and the beam quality of an alternative cell satisfies condition (12), it can be regarded as that the current beams in the current cell all satisfy condition (12), or the current beams in the cell used to determine the first result satisfy condition (12), and the alternative beams in the alternative cell all satisfy condition (12), or the alternative beams in the alternative cell used to determine the second result satisfy condition (12). For the specific contents of the first result and the second result, please refer to the relevant description above.

[0313] Assume that cell 1 is the current cell and cell 2 is the candidate cell, the M beams in cell 1 are the current beams and the N beams in cell 2 are the candidate beams, the beam quality of the M current beams of cell 1 obtains a first result, and the beam quality of the N candidate beams of cell 2 obtains a second result of cell 2. If the difference obtained by subtracting the first result of cell 1 from the second result of cell 2 is greater than or equal to the eleventh threshold value, then cell 1 meets condition (12) and cell 2 meets condition (12). Conversely, if the difference obtained by subtracting the first result of cell 1 from the second result of cell 2 is less than the eleventh threshold value, then cell 1 and cell 2 do not meet condition (12).

[0314] In another possible implementation, the beam quality of the current cell refers to the beam quality of at least one current beam in the current cell, and the beam quality of the candidate cell refers to the beam quality of at least one candidate beam in the candidate cell.

[0315] Specifically, assuming that M beams in a current cell are current beams and N beams in a candidate cell are candidate beams, condition (12) can be understood as follows, but is not limited to the following understanding:

[0316] In an example, condition (12) can be understood as: the beam quality of each of the N alternative beams in the alternative cell is greater than or equal to the beam quality of all current beams in the current cell, and the difference between the beam quality of each alternative beam and the beam quality of each current beam is greater than or equal to the eleventh threshold value.

[0317] In another example, condition (12) can be understood as: the beam quality of at least N" beams among the N alternative beams in the alternative cell satisfies: the beam quality is greater than or equal to the beam quality of all current beams in the current cell, and the difference between the beam quality and the beam quality of each current beam is greater than or equal to the eleventh threshold value. Wherein, N" is a positive integer, and N"≤N.

[0318] In another example, condition (12) can be understood as follows: for each current beam in the current cell, there is at least one alternative beam in the candidate cell that satisfies: yx ≥ threshold_11, where x represents the beam quality of the current beam, y represents the beam quality of the alternative beam, and threshold_11 represents the eleventh threshold value. In other words, condition (12) can also be understood as follows: the alternative beams of the candidate cell include: at least one alternative beam corresponding to each current beam in the current cell, where each current beam and each alternative beam corresponding to the current beam satisfies: yx ≥ threshold_11.

[0319] Condition (13): The beam interference of the current cell is greater than or equal to the twelfth threshold.

[0320] Specifically, the beam interference of the current cell being greater than or equal to the twelfth threshold value may mean that the beam interference of at least one current beam in the current cell is greater than or equal to the twelfth threshold value. Among them, the current beam whose beam interference is greater than or equal to the twelfth threshold value can be considered to meet condition (13).

[0321] In a possible implementation, for a current cell, the beam interference of the current cell may be a third result obtained based on the beam interference of at least one current beam in the current cell.

[0322] Assuming that M beams in a current cell are current beams, where M is a positive integer, the third result is exemplarily described below with reference to a specific example.

[0323] Example 1: The third result is the beam interference of the beam with the largest or smallest beam interference among the M current beams.

[0324] Example 2: The third result is the average value of the beam interferences of the M current beams.

[0325] Example 3: The third result is the average value of the beam interferences of the M' beams with the largest or smallest beam interference among the M current beams, where M' is a positive integer greater than 1, and M'≤M.

[0326] Example 4: The third result is the average value of the beam interference of the beams in the M current beams whose beam interference is greater than or equal to the thirteenth threshold value, or the first result is the average value of the beam interference of the beams in the M current beams whose beam interference is less than or equal to the thirteenth threshold value.

[0327] In another possible implementation, for a current cell, the M beams within the current cell are current beams. If the beam interference of any one of the M current beams is greater than or equal to the twelfth threshold value, the current cell meets condition (13).

[0328] In another possible implementation, for a current cell, the M beams in the current cell are current beams. If the beam interference of each beam in the M current beams is greater than or equal to the twelfth threshold value, then the current cell meets condition (13).

[0329] In another possible implementation, for a current cell, M beams within the current cell are current beams. If the beam interference of at least A beams among the M current beams is greater than or equal to a twelfth threshold value, then the current cell satisfies condition (13). Wherein, A is a positive integer, A≤M. The value of A may be configured by a network device or defined by a protocol.

[0330] Condition (14): The beam interference of the candidate cell is less than or equal to the fourteenth threshold.

[0331] Specifically, the beam interference of the candidate cell is less than or equal to the fourteenth threshold value may mean that the beam interference of at least one candidate beam in the candidate cell is less than or equal to the fourteenth threshold value. Among them, the candidate beam with beam interference less than or equal to the fourteenth threshold value can be considered to meet condition (14).

[0332] In a possible implementation, for a candidate cell, the beam interference of the candidate cell may be a fourth result obtained based on the beam interference of at least one candidate beam in the candidate cell.

[0333] Assuming that N beams in a candidate cell are candidate beams, where N is a positive integer, the fourth result is exemplarily described below with reference to a specific example.

[0334] Example 1: The fourth result is the beam interference of the beam with the largest or smallest beam interference among the N candidate beams.

[0335] Example 2: The fourth result is the average value of the beam interferences of the N candidate beams.

[0336] Example 3: The fourth result is the average value of the beam interferences of N' beams with the largest or smallest beam interference among the N candidate beams, where N' is a positive integer greater than 1, and N'≤N.

[0337] Example 4: The fourth result is the average value of the beam interference of the beams whose beam interference is greater than or equal to the fifteenth threshold value among the N alternative beams, or the first result is the average value of the beam interference of the beams whose beam interference is less than or equal to the fifteenth threshold value among the N alternative beams.

[0338] In one possible implementation, for a candidate cell, N beams within the candidate cell are candidate beams. If the beam interference of any one of the N candidate beams is less than or equal to the fourteenth threshold value, the candidate cell meets condition (14).

[0339] In another possible implementation, for a candidate cell, N beams within the candidate cell are candidate beams. If the beam interference of each beam in the N candidate beams is less than or equal to the fourteenth threshold value, then the candidate cell meets condition (14).

[0340] In another possible implementation, for a candidate cell, N beams within the candidate cell are candidate beams. If the beam interference of at least B beams among the N candidate beams is less than or equal to an eleventh threshold value, then the candidate cell meets condition (14). Wherein, B is a positive integer, B≤N. The value of B can be configured by the network device or defined by the protocol.

[0341] Condition (15): The beam interference of the candidate cell is less than or equal to the beam interference of the current cell.

[0342] Specifically, the beam interference of the candidate cell is less than or equal to the beam interference of the current cell, which may mean that the fourth result of the candidate cell is less than or equal to the third result of the current cell. Alternatively, the beam interference of the candidate cell is less than or equal to the beam interference of the current cell, which may mean that the beam interference of at least one candidate beam in the candidate cell is less than or equal to the beam interference of at least one current beam in the current cell.

[0343] In one example, for a current cell, if the beam interference of each of the N alternative beams in an alternative cell is less than or equal to the beam interference of all current beams in the current cell, then the current cell and the alternative cell meet condition (15).

[0344] In another example, for a current cell, if the beam interference of at least C candidate beams among N candidate beams in a candidate cell is less than or equal to the beam interference of all current beams in the current cell, then the current cell and the candidate cell meet condition (15). Where C is a positive integer, C ≤ N. The value of C can be configured by the network device or defined by the protocol.

[0345] In another example, for each current beam in a current cell, if the N candidate beams of a candidate cell include: at least one candidate beam corresponding to each current beam, then the current cell and the candidate cell meet condition (15). The beam interference of the candidate beam corresponding to each current beam is less than or equal to the beam interference of the current beam. The at least one candidate beam corresponding to different current beams may be the same or different.

[0346] Condition (16): The beam interference of the candidate cell is less than or equal to the beam interference of the current cell, and the difference between the beam interference of the current cell and the beam interference of the candidate cell is greater than or equal to the sixteenth threshold.

[0347] Specifically, condition (16) may mean that the fourth result of the candidate cell is less than or equal to the third result of the current cell, and the difference between the third result of the current cell and the fourth result of the candidate cell is greater than or equal to the sixteenth threshold.

[0348] Alternatively, condition (16) may mean that the beam interference of at least one alternative beam in the alternative cell and the beam interference of at least one current beam in the current cell satisfy: the beam interference of the alternative beam is less than or equal to the beam interference of the current beam, and the difference between the beam interference of the current beam and the beam interference of the alternative beam is greater than or equal to the sixteenth threshold value.

[0349] In one example, for a current cell, if the beam interference of each of the N candidate beams in a candidate cell and the beam interference of all current beams in the current cell satisfy: x'–y'≥threshold_16, then the current cell and the candidate cell meet condition (16), where x' represents the beam interference of the current beam, y' represents the beam interference of the candidate beam, and threshold_16 represents the sixteenth threshold value.

[0350] In another example, for a current cell, if the beam interference of at least C candidate beams among N candidate beams in a candidate cell and the beam interference of all current beams in the current cell satisfy: x'–y'≥threshold_16, then the current cell and the candidate cell meet condition (16). Where C is a positive integer, C≤N. The value of C can be configured by the network device or defined by the protocol.

[0351] In another example, for each current beam in a current cell, if the N candidate beams of a candidate cell include: at least one candidate beam corresponding to each current beam, then the current cell and the candidate cell meet condition (16). Wherein, each current beam and the candidate beam corresponding to the current beam meet: x'–y'≥threshold_16, then the current cell and the candidate cell meet condition (16). Wherein, the at least one candidate beam corresponding to different current beams may be the same or different.

[0352] It should be noted that the specific contents about the beam quality of the cell and the beam interference of the cell can be referred to the relevant description above and will not be repeated here.

[0353] In a specific implementation, the above-mentioned condition may refer to the entry condition of the first event. After the entry condition is met, the terminal device may determine the number of consecutive times the entry condition is met based on the counter and timer of the first process to detect the first event. The "counter" and "timer" in this embodiment may be a counter and timer of the MAC layer. Alternatively, the terminal device may filter multiple consecutive measurement results and determine whether the event condition is met based on the filtered results.

[0354] It should be noted that the measurement threshold corresponding to the first event may refer to the threshold involved in conditions (1) to (16) above. This document does not limit the values ​​of the various thresholds involved in this document. The values ​​of the various thresholds may be configured by the network device and / or defined by the protocol.

[0355] 2. Configuration of RS resources

[0356] For ease of description, the RS resources used for the first process will be referred to as "first RS resources" below. The first RS resources are used to detect the first event. In other words, the first RS resources may include a first RS resource for detecting a failed beam, and / or a first RS resource for detecting a first new beam. The first RS resource may be at least one of the following: a positioning reference signal (PRS) resource, a CSI-RS resource, an SSB resource, etc., but is not limited thereto. The RS transmitted on the first RS resource is recorded as the first RS, and "the first RS resource is used to detect the first event" can also be replaced with "the first RS is used to detect the first event". Specifically, the first RS may include: a first RS for detecting a failed beam and / or a first RS for detecting a first new beam.

[0357] Exemplarily, the first configuration information may include at least one RS transmission parameter, and the RS transmission parameter may be associated with the first event. For example, the "RS transmission parameter" may refer to a first RS resource configuration, wherein the first RS resource configuration may include at least one first RS resource set, and each first RS resource set may include at least one first RS resource. Alternatively, the "RS transmission parameter" may refer to a first RS resource set, and each first RS resource set may include at least one first RS resource. Alternatively, the "RS transmission parameter" may refer to a first RS resource.

[0358] In one possible implementation, the RS transmission parameter may be associated with the first event. The association between the RS transmission parameter and the first event may be understood as follows: for a first event, the terminal device uses the RS transmission parameter associated with the first event to perform measurement to detect the first event.

[0359] 3. Configuration of uplink transmission resources

[0360] Specifically, the network device may configure an uplink transmission resource for the terminal device to send the first information. It should be noted that the uplink transmission resource in this article may be a physical uplink control channel (PUCCH) resource, or a physical uplink shared channel (PUSCH) resource. Among them, the PUSCH resource may be a periodic PUSCH resource, or may be a PUSCH resource with a configured grant (CG).

[0361] 4. Counter configuration and timer configuration

[0362] Specifically, the counters of the first process may include at least one of the following: a counter for current beam measurement, a counter for current cell measurement, a counter for new beam detection, and a counter for new cell detection. It should be noted that "current beam measurement" herein can be understood as determining whether the current beam is a failed beam or detecting a failed beam.

[0363] More specifically, a counter for current beam measurement can count the number of times the current beam satisfies a first event or a condition. If the counter for current beam measurement reaches a maximum count value, the current beam is determined to be a failed beam. A counter for new beam detection can count the number of times an alternative beam satisfies a first event or a condition. If the counter for new beam detection reaches a maximum count value, the alternative beam is determined to be the first new beam. The counter for current beam measurement and the current beam can have a one-to-one correspondence, and the counter for new beam detection and the alternative beam can have a one-to-one correspondence.

[0364] As described above, the process of detecting the first event may also involve the determination of cell-level beam quality and / or cell-level beam interference. To this end, the counter used for current cell measurement can count whether the current cell meets the first event or the number of times the condition is met. If the counter used for current cell measurement reaches the maximum count value, the current cell is determined to be a failed cell. The counter used for new cell detection can count whether the alternative cell meets the first event or the number of times the condition is met. If the counter used for new cell detection reaches the maximum count value, the alternative cell is determined to be the first new cell. The counter used for current cell measurement and the current cell may have a one-to-one correspondence, and the counter used for new cell detection and the alternative cell may have a one-to-one correspondence.

[0365] The timers of the first process may include at least one of the following: a timer for current beam measurement, a timer for current cell measurement, a timer for new beam detection, and a timer for new cell detection. The timers of the first process may correspond to the counters of the first process. For example, the timers and counters may correspond one-to-one, or multiple timers may correspond to one counter, or multiple counters may correspond to one timer. During the counting process of the counter, when the counter value increases by 1, the corresponding timer is restarted. When the timer times out, the counter is reset to zero and starts counting again.

[0366] From the above, the parameters used for the first process may include at least one of the following: configuration of the first event, configuration of the first RS resource or the first RS transmitted on the first RS resource, configuration of the uplink transmission resource for sending the first information, configuration of the counter of the first process, timer of the first process, or configuration of the measurement threshold value of the first process.

[0367] Furthermore, the parameters used for the second process may include at least one of the following: configuration of the second RS resource, configuration of the uplink transmission resource of the second process, configuration of the counter of the second process, timer of the second process, or configuration of the measurement threshold value of the second process.

[0368] The second process herein may be a BFR process. In this case, the second configuration information may refer to the configuration information of the BFR process. Specifically, the parameters used for the BFR process include at least one of the following: BFDRS resources, NBIRS resources, a counter for beam failure detection (BFD), a timer for BFD, a counter for new beam identification (NBI), a timer for NBI, uplink transmission resources for sending BFRQ, a measurement threshold for BFD, and a measurement threshold for NBI. The counter used for BFD can also be described as a "counter for counting BFIs." In other words, the second RS resources may include: BFDRS resources and / or NBIRS resources. Correspondingly, the second RS may include BFDRS resources and / or NBIRS. The uplink transmission resources of the BFR process may include uplink transmission resources for sending BFRQ. The counters of the BFR process may include: a counter for BFD and a counter for NBI. The timers of the BFR process may include: a timer for BFD and a timer for NBI. The measurement threshold value of the BFR process may include: a measurement threshold value for BFD and a measurement threshold value for NBI.

[0369] It should also be noted that the terminal device can perform the BFR process on each service cell, and the network device can configure a counter for BFD, a timer for BFD, a counter for NBI and a timer for NBI for each service cell.

[0370] In a specific implementation, the first RS resource configured by the network device for detecting a failed beam and the BFDRS resource configured by the network device may be the same or different. The first RS resource configured by the network device for detecting a new beam and the NBIRS resource configured by the network device may be the same or different.

[0371] For more information about BFR configuration information, please refer to the relevant description of the existing protocol and will not be repeated here.

[0372] Alternatively, the second process herein may refer to an RLM process. In this case, the second configuration information may refer to configuration information of the RLM process. Specifically, the parameters used for the RLM process may include at least one of the following: RLM-RS resources, RLM process counters (such as N310, N311), RLM process timers (such as T310, etc.), uplink transmission resources for sending radio link failure information and / or RRC re-establishment requests, and physical random access channel (PRACH) resources for initiating random access.

[0373] In other words, the second RS resource may include an RLM-RS resource. Correspondingly, the second RS may include an RLM-RS. The uplink transmission resource for the RLM process may include at least one of the following: an uplink transmission resource for transmitting radio link failure information, an uplink transmission resource for transmitting an RRC reestablishment request, or a PRACH resource for initiating random access. The counters for the RLM process may include N310 and N311. The timer for the RLM process may include T310.

[0374] For more information about the configuration information of RLM, please refer to the relevant description of the existing protocol and will not be repeated here.

[0375] In one possible implementation, the configuration information includes parameters for the first process and parameters for the second process. That is, the network device is configured with two sets of parameters: one set for the first process and the other set for the second process. The parameters for the first process may be associated with the parameters for the second process. For details about the parameters for the first process and the parameters for the second process, please refer to the above description and will not be repeated here.

[0376] Exemplarily, if the parameters used for the first process are associated with the parameters used for the second process, the terminal device may determine to execute the solution provided in the embodiment of the present application.

[0377] Exemplarily, at least one of the parameters used for the first process and at least one of the parameters used for the second process may be the same. In other words, the first process and the second process may share at least one of uplink transmission resources, reference signal resources, counters, timers, or measurement thresholds.

[0378] In another possible implementation, the configuration information includes parameters for the first process and the second process. That is, the network device configures a set of parameters, which are used for the first process and the second process. The phrase "parameters used for the first process and the second process" can be understood to mean that the parameters are used for both the first process and the second process. Specifically, the parameters used for the first process and the second process may include at least one of the following: uplink transmission resource configuration, reference signal resource configuration, counter configuration, timer configuration, and measurement threshold configuration. In this case, the first process and the second process may share at least one of the following: uplink transmission resource configuration, reference signal resource configuration, counter configuration, timer configuration, or measurement threshold configuration.

[0379] In one example, the first process and the second process may share uplink transmission resources. In other words, the uplink transmission resources configured by the configuration information may be used to transmit the first information in the first process, and may also be used to transmit uplink information (such as BFRQ, radio link failure information, and RRC reestablishment request) in the second process.

[0380] In an example, the first process and the second process sharing uplink transmission resources may mean that the first information and the uplink information in the second process may be carried in the same uplink transmission resources.

[0381] Furthermore, in the case where the first process and the second process share uplink transmission resources, the uplink information in the first process and the uplink information in the second process can be distinguished by the information carried on the uplink transmission resources. Specifically, the first information and the uplink information in the second process can be carried in Media Access Control-Control Element (MAC CE) signaling, and the first information in the first process and the uplink information in the second process can be distinguished by the header information of the MACCE signaling or the indication information carried in the MACCE signaling. Alternatively, the first information in the first process can be carried in Uplink Control Information (UCI) signaling, and the uplink information in the second process can be carried in MACCE signaling. Alternatively, the first information in the first process can be carried in Uplink Control Information (UCI) signaling, and the uplink information in the second process can be carried in MACCE signaling. Alternatively, the first information in the first process and the uplink information in the second process can both be carried in UCI signaling, and the first information in the first process and the uplink information in the second process can be distinguished by the indication information in the UCI signaling.

[0382] In another example, the first process and the second process may share RS resources. Specifically, the first process and the second process sharing RS resources may include: the RS resources used for current beam measurement in the first process and the RS resources used for BFD in the second process may be the same, and / or the RS resources used for new beam detection in the first process and the RS resources used for NBI may be the same.

[0383] For example, the RS resources shared by the first process and the second process may be periodic or semi-persistent RS resources, and the terminal device may perform measurements at different transmission times of the shared RS resources to perform measurements in the first process and measurements in the second process respectively.

[0384] For another example, the terminal device performs measurements on the shared RS resources (such as performing measurements at the same transmission timing of the shared RS resources) to obtain the measurement results of the first process and the measurement results of the second process. Furthermore, the terminal device compares the measurement results of the first process with the measurement threshold value of the first process to determine whether the first event occurs, and compares the measurement results of the second process with the measurement threshold value of the second process to determine whether a beam failure event occurs and / or whether an RLF event occurs and / or whether the beam corresponding to the shared RS resource is a new beam. The measurement results of the first process and the measurement results of the second process may be the same type of measurement results (such as both are RSRP, or both are SINR), or the measurement results of the first process and the measurement results of the second process may be different types of measurement results (such as the measurement result of the first process is RSRP, and the measurement result of the second process is SINR; or the measurement result of the second process is RSRP, and the measurement result of the first process is SINR).

[0385] In other words, the RS resources configured by the configuration information for current beam measurement can be used to measure the current beam in the first process, and can also be used to measure the current beam in the second process. For example, the RS resources configured by the configuration information for current beam measurement can be used as the first RS resources for current beam measurement, and can also be used as BFDRS resources or RLM-RS resources. The RS resources configured by the configuration information for new beam detection can be used to measure alternative beams to identify new beams in the first process, and can also be used to measure alternative beams to identify new beams in the second process. For example, the RS resources configured by the configuration information for new beam detection can be used as the first RS resources for new beam detection, and can also be used as NBIRS resources.

[0386] In another example, the first process and the second process may share a counter. Specifically, the counter configured by the configuration information may be used for counting in the first process as well as for counting in the second process.

[0387] Illustratively, during execution of the first process, the terminal device may use a counter shared by the first process and the second process to perform counting to detect the first event. Furthermore, after the terminal device stops the first process and starts the second process, the terminal device may continue to use the counter shared by the first process and the second process to perform counting to detect a beam failure event and / or an RLF event and / or identify a new beam.

[0388] As another example, during execution of the second process, the terminal device may use a counter shared by the first process and the second process to count to detect a beam failure event and / or an RLF event and / or identify a new beam. Furthermore, after the terminal device stops the second process and starts the first process, the terminal device may continue to use the counter shared by the first process and the second process to count to detect the first event.

[0389] For example, the counter configured by the configuration information can be used to count the number of times the current beam meets the first event or condition in the first process, and can also be used to count BFIs in the BFR process. For another example, the counter configured by the configuration information can be used to count the number of times the alternative beam meets the first event or condition in the first process, and can also be used to count the number of times the measurement results of the NBIRS resources exceed the measurement threshold value in the BFR process.

[0390] For another example, the configuration information can be used to configure counters for various cells (such as a serving cell and a candidate cell). The counter on each serving cell can be used to count the number of times the serving cell satisfies the first event in the first process, and can also be used to count the BFI on the serving cell. The counter on each candidate cell can be used to count the number of times the candidate cell satisfies the first event in the first process, and can also be used to count new beams on the candidate cell in BFR.

[0391] In another example, the first process and the second process may share a timer. Specifically, the timer configured by the configuration information may be used for timing in both the first process and the second process. The timer for the first process and the timer for the second process may be the same timer.

[0392] For example, when the counter of the first process is started but the counter of the second process is not started, if the timer of the first process and the timer shared by the second process expire, the counter of the first process is reset to zero and restarts counting; if the value of the counter of the first process is increased by 1, the timer of the first process and the timer shared by the second process are restarted.

[0393] As another example, when the counter of the second process is started but the counter of the first process is not started, if the timer of the first process and the timer shared by the second process expire, the counter of the second process is reset to zero and restarts counting; if the value of the counter of the second process is increased by 1, the timer of the first process and the timer shared by the second process are restarted.

[0394] For another example, when both the counter of the first process and the counter of the second process are enabled, if the timer of the first process and the timer shared by the second process expire, the counter of the first process and the counter of the second process are both reset to zero and restart. If the value of the counter of the first process is incremented by 1 or the value of the counter of the second process is incremented by 1, the timer of the first process and the timer shared by the second process are restarted.

[0395] In another example, the first process and the second process may share a measurement threshold value. Sharing the measurement threshold value between the first process and the second process may include at least one of the following situations: the measurement threshold value used in the first information for detecting the first event and the measurement threshold value used in the second process for detecting a beam failure event may be the same; the measurement threshold value used in the first information for detecting the first event and the measurement threshold value used in the second process for identifying a new beam may be the same; the measurement threshold value used in the first information for detecting the first event and the measurement threshold value used in the second process for detecting an RLF event may be the same.

[0396] For example, the measurement threshold value configured by the configuration information can be used to compare with the beam quality and / or beam interference of the current beam in the first process to determine whether the current beam is a failed beam, and can also be used to compare with the measurement results of the BFDRS resources in the BFR process to determine whether a beam failure event has occurred. For another example, the measurement threshold value configured by the configuration information can be used to compare with the beam quality and / or beam interference of the current beam in the first process to determine whether the current beam is a failed beam, and can also be used to compare with the measurement results of the RLM-RS resources in the RLF process to determine whether an RLF event has occurred. For another example, the measurement threshold value configured by the configuration information can be used to compare with the beam quality and / or beam interference of the alternative beam in the first process to determine whether the alternative beam is a new beam, and can also be used to compare with the measurement results of the NBI RS resources in the BFR process to determine whether the beam corresponding to the NBI RS resource is a new beam.

[0397] As described above, in the solution of embodiment 1, the network device provides the terminal device with parameters for the first process and / or, so that the terminal device can execute the first process and the second process based on the parameters for the first process and / or.

[0398] For more details about the first embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0399] Example 2

[0400] Reference Figure 2 , Figure 2 It is a flow chart of the second communication method in the embodiment of the present application. Figure 2The method shown can be applied to a communication device. Specifically, Figure 2 The method shown can be applied to a terminal device or a network device. Figure 2 In the illustrated scheme, the BFR process may trigger the first process. Figure 2 The illustrated method may include S21 and S22.

[0401] S21, start the BFR process;

[0402] S22: In response to the first starting condition being met, starting the first process.

[0403] In one possible implementation of S21, after the network device configures the terminal device with parameters for BFR, the terminal device may initiate a BFR process. More specifically, in S21, the terminal device may initiate a BFR process based on the configuration of the network device. In a specific implementation, initiating the BFR process by the terminal device may include at least one of the following: the terminal device requests parameters for the BFR process; the terminal device receives configuration information including parameters for the BFR process (such as the second configuration information or the configuration information described above); the terminal device receives BFDRS and / or NBIRS; the terminal device measures BFDRS and / or NBIRS; the terminal device detects a beam failure event; the terminal device identifies a new beam; a counter for BFD is started; and a counter for NBI is started.

[0404] In another possible implementation of S21, the network device may initiate a BFR process. Specifically, the network device initiating the BFR process may include at least one of the following: the network device configuring parameters for the BFR process (that is, the network device sending configuration information including parameters for the BFR process (such as the second configuration information or the configuration information above)), the network device sending a BFDRS and / or an NBIRS, and the network device confirming or knowing that the terminal device has initiated the BFR process.

[0405] It should be noted that starting the BFR in S21 may be independent of the first process. That is, starting the BFR in S21 may not depend on the first process.

[0406] Furthermore, after the BFR process is initiated, in S22, the terminal device or network device may determine whether a first initiation condition is met. The first initiation condition is used to trigger the initiation of the first process. Specifically, if the first initiation condition is determined to be met, the terminal device or network device initiates the first process. In other words, if the first initiation condition is determined not to be met, the terminal device or network device does not initiate the first process. Furthermore, if the first process is not initiated, the second process may continue.

[0407] The first starting condition is related to the BFR process. Specifically, the first starting condition may include at least one of the following starting conditions (1) to (11).

[0408] Start condition (1): The terminal device does not detect a beam failure event during the BFR process.

[0409] Specifically, if the terminal device does not detect a beam failure event within the first time window, it may be determined that the start condition (1) is met. If the terminal device detects a beam failure event within the first time window, it may be determined that the start condition (1) is not met.

[0410] The starting time of the first time window may be: the time when the network device configures the BFR process. For example, the network device may configure a beam failure recovery timer (beamFailureRecoveryTimer), and the time when the network device configures the BFR process may be the time when the beamFailureRecoveryTimer starts timing.

[0411] Alternatively, the starting moment of the first time window can be any one of the following: the transmission moment of the first BFDRS, the transmission moment of the first NBIRS, or the moment when the terminal device detects the second new beam.

[0412] The duration of the first time window can be configured by the network device. For example, the network device can configure the duration of the beamFailureRecoveryTimer, and the duration of the first time window can be the same as the duration of the beamFailureRecoveryTimer. In other words, if the beamFailureRecoveryTimer times out and the terminal device does not detect a beam failure event, the initiation condition of the first process is met. In other embodiments, the duration of the first time window can also be defined by the protocol.

[0413] It should be noted that the “moment” in this document can be understood as at least one of the following: symbol, slot, frame, subframe, second, millisecond, etc., but is not limited thereto.

[0414] It should also be noted that the "moment when the network device configures the BFR process" in this article can be understood or described as at least one of the following: the moment when the network device configures the parameters for BFR, the moment when the configuration information including the parameters for BFR (such as the configuration information or the second configuration information in Example 1) is transmitted (such as the moment when the network device sends the configuration information including the parameters for BFR, the moment when the terminal device receives the configuration information including the parameters for BFR).

[0415] It should also be noted that the "transmission time of the first BFDRS" herein can be understood or described as at least one of the following: "the starting time when the terminal device receives the first BFDRS", "the starting time when the network device sends the first BFDRS", "the starting time when the terminal device measures the first BFDRS", or "the starting time when the terminal device detects a beam failure event". The "transmission time of the first NBIRS" herein can be understood or described as at least one of the following: "the starting time when the terminal device receives the first NBIRS", "the starting time when the network device sends the first NBIRS", "the starting time when the terminal device measures the NBIRS", or "the starting time when the terminal device detects the second new beam".

[0416] Start condition (2): The terminal device does not recognize the second new beam during the BFR process.

[0417] Specifically, if the terminal device does not detect the second new beam within the second time window, the terminal device may determine that the start condition (2) is met. If the terminal device detects the second new beam within the second time window, it may determine that the start condition (2) is not met.

[0418] The starting time of the second time window can be any of the following: the time when the network device configures the BFR process, the time when the first BFDRS is transmitted, the time when the first NBIRS is transmitted, or the time when the terminal device detects a beam failure event. The duration of the second time window can be configured by the network device. For example, the duration of the second time window can be the duration of the beamFailureRecoveryTimer. That is, if the beamFailureRecoveryTimer times out and the terminal device does not identify the second new beam, the start condition of the first process is met. In other embodiments, the duration of the second time window can also be defined by the protocol.

[0419] The second new beam may include: a new beam in the serving cell and / or a new beam in the alternative cell.

[0420] In one example, if the terminal device does not detect the second new beam within the current serving cell within the second time window, the terminal device may initiate the first process.

[0421] In another example, if the terminal device does not detect the second new beam in the candidate beams of the candidate cell within the second time window, the terminal device may initiate the first process.

[0422] In another example, the second new beam may include a second new beam in the current serving cell and a second new beam in the alternative cell. That is, if the terminal device does not identify the new beam in the current serving cell or detect the second new beam in the alternative cell within the second time window, the terminal device may initiate the first process.

[0423] Start condition (3): The BFRQ does not include information about the second new beam, or the BFRQ includes indication information that the second new beam is not detected.

[0424] Specifically, during the BFR process, the terminal device can send a BFRQ to the network device. If the BFRQ sent by the terminal device or the BFRQ to be sent does not include information about the second new beam, or the BFRQ includes indication information that the second new beam is not detected, it can be determined that the start condition (3) is met. Exemplarily, if the BFRQ does not include information about the second new beam, or the BFRQ includes indication information that the second new beam is not detected, it can be understood that the terminal device has not identified the second new beam. Conversely, if the BFRQ includes information about the second new beam, it can be determined that the start condition (3) is not met. The second new beam can include the second new beam in the current serving cell and the second new beam in the alternative cell.

[0425] In one example, if the BFRQ to be sent does not include information about the second new beam, or the BFRQ includes indication information that the second new beam is not detected, the terminal device can start the first process and cancel sending the BFRQ.

[0426] Start condition (4): BFRQ does not contain information about the second new cell.

[0427] Specifically, during the BFR process, the terminal device may send a BFRQ to the network device. If the BFRQ sent by the terminal device or the BFRQ to be sent does not include information about the second new cell, it may be determined that the start condition (4) is met. Conversely, if the BFRQ includes information about the second new cell, it may be determined that the start condition (4) is not met.

[0428] Start condition (5): The terminal device does not receive the BFRR.

[0429] Specifically, during the BFR process, after receiving the BFRQ, the network device may send a BFRR to the terminal device. If the terminal device does not receive the BFRR within the third time window, it may be determined that the start condition (5) is met. If the terminal device receives the BFRR within the third time window, it may be determined that the start condition (5) is not met.

[0430] The starting time of the third time window can be any of the following: the time when the network device configures the BFR process, the time when the first BFDRS is transmitted, the time when the first NBIRS is transmitted, the time when the terminal device detects a beam failure event, the time when the terminal device detects the second new beam, and the time when the BFRQ is transmitted (such as the time when the terminal device sends the BFRQ). The duration of the third time window can be configured by the network device. Alternatively, the duration of the third time window can also be defined by the protocol.

[0431] For example, if the terminal device does not receive a BFRR within a preset time period (i.e., the time period of the third time window) after detecting a beam failure event, then the initiation condition (5) is satisfied. For another example, if the terminal device does not receive a BFRR within a preset time period (i.e., the time period of the third time window) after sending a BFRQ, then the initiation condition (5) is satisfied.

[0432] Reference Figure 14 , Figure 14 This is a timing diagram of the start-up conditions in the embodiment of the present application. Figure 14 As shown, assuming that the terminal device detects a beam failure event at t1, the preset duration is T. If the terminal device does not receive a BFRR within the time period from t1 to (t1+T), the start condition (5) is met. If the terminal device receives a BFRR within the time period from t1 to (t1+T), the start condition (5) is not met.

[0433] Start condition (6): The BFR process is not completed.

[0434] Specifically, if the BFR process is not completed within the fourth time window, it can be determined that the start condition (6) is met. In other words, if the BFR is not successfully completed within the fourth time window, it can be determined that the start condition (6) is met. If the BFR process is successfully completed within the fourth time window, it can be determined that the start condition (6) is not met.

[0435] Among them, the starting moment of the fourth time window can be any one of the following: the moment when the network device configures the BFR process, the transmission moment of the first BFDRS, the transmission moment of the first NBIRS, the moment when the terminal device detects the beam failure event, the moment when the terminal device detects the second new beam, the transmission moment of BFRQ (such as the moment when the terminal device sends BFRQ, the moment when the network device receives BFRQ), the transmission moment of BFRR (such as the moment when the terminal device receives BFRR, the moment when the network device sends BFRR). Among them, the duration of the fourth time window can be configured by the network device, such as the duration of beamFailureRecoveryTimer. Alternatively, the duration of the fourth time window can also be defined by the protocol.

[0436] In one example, the terminal device detects a beam failure event on the primary cell. The terminal device may initiate random access on the primary cell. If the random access is completed, the BFR process is completed.

[0437] In another example, the terminal device receives a BFRR after sending a BFRQ, or switches to a new beam after receiving a BFRR, and the BFR process is completed.

[0438] In yet another example, after the terminal device detects a beam failure event on a secondary cell, if the secondary cell in which the beam failure event is detected is deactivated, the BFR process is completed.

[0439] In another example, the network device sends a PDCCH to the terminal device, where the PDCCH indicates an uplink grant for a new transmission, and the HARQ process used for the uplink transmission scheduled by the PDCCH is used for the terminal device to send a BFRQ, and the BFR process is completed.

[0440] Start condition (7): The terminal device does not switch to the second new beam during the BFR process.

[0441] Specifically, if the terminal device does not switch to the second new beam within the fifth time window, it can be determined that the start condition (7) is met. If the terminal device switches to the second new beam within the fifth time window, it can be determined that the start condition (7) is not met.

[0442] Among them, the fifth time window can be any one of the following: the moment when the network device configures the BFR process, the transmission moment of the first BFDRS, the transmission moment of the first NBIRS, the moment when the terminal device detects the beam failure event, the moment when the terminal device detects the second new beam, the transmission moment of BFRQ (such as the moment when the terminal device sends BFRQ), the transmission moment of BFRR (such as the moment when the terminal device receives BFRR). For example, the starting moment of the fifth time window can be the moment when beamFailureRecoveryTimer starts timing. Among them, the duration of the fifth time window can be configured by the network device. Alternatively, the duration of the fifth time window can also be defined by the protocol.

[0443] Start condition (8): The terminal device does not switch to the second new cell during the BFR process.

[0444] Specifically, if the terminal device does not switch to the second new cell within the sixth time window, it can be determined that the start condition (8) is met. If the terminal device switches to the second new cell within the sixth time window, it can be determined that the start condition (8) is not met.

[0445] Among them, the sixth time window can be any one of the following: the moment when the network device configures the BFR process, the transmission moment of the first BFDRS, the transmission moment of the first NBIRS, the moment when the terminal device detects the beam failure event, the moment when the terminal device detects the second new beam, the transmission moment of BFRQ (such as the moment when the terminal device sends BFRQ), the transmission moment of BFRR (such as the moment when the terminal device receives BFRR). For example, the starting moment of the sixth time window can be the moment when beamFailureRecoveryTimer starts timing. Among them, the duration of the sixth time window can be configured by the network device. Alternatively, the duration of the sixth time window can also be defined by the protocol.

[0446] Start condition (9): The terminal device receives first indication information, and the first indication information is used to indicate the start of the first process.

[0447] Specifically, after initiating the BFR process, the network device may send first indication information to the terminal device. If the terminal device receives the first indication information after initiating the BFR process, it may be determined that the initiation condition (9) is met. If the terminal device does not receive the first indication information, the initiation condition (9) is not met.

[0448] More specifically, if the terminal device receives the first indication information within the seventh time window, it can be determined that the start condition (9) is met. The starting time of the seventh time window can be any one of the following: the time when the network device configures the BFR process, the transmission time of the first BFDRS, the transmission time of the first NBIRS, the time when the terminal device detects a beam failure event, the time when the terminal device identifies the second new beam, the transmission time of BFRQ (such as the time when the terminal device sends BFRQ), the transmission time of BFRR (such as the time when the terminal device receives BFRR). The duration of the seventh time window can be configured by the network device. Alternatively, the duration of the seventh time window can also be defined by the protocol.

[0449] In a specific implementation, whether to send the first indication information and the timing of sending the first indication information may depend on the autonomous decision of the network device.

[0450] In one example, if the network device receives a BFRQ, the network device may send first indication information to the terminal device. Specifically, if the network device receives a BFRQ within the eighth time window, the network device may send the first indication information to the terminal device. The start time of the eighth time window may be the time when the network device configures the BFR process. The duration of the eighth time window may be configured by the network device. Alternatively, the duration of the eighth time window may be defined by a protocol.

[0451] In another example, if the network device does not receive a BFRQ within the ninth time window, the network device may send a first indication message to the terminal device. If the network device does not receive a BFRQ within the ninth time window, the network device may deem that no beam failure event has been detected, and the network device may instruct to start a first process to identify the deterioration of beam quality in the current beam through the first process, so as to promptly know and respond to the deterioration of signal quality. Specifically, if the network device receives a BFRQ within the ninth time window, the network device may send a BFRR to the terminal device without sending the first indication message. The starting moment of the ninth time window may be the moment when the network device configures the BFR process. The duration of the ninth time window may be configured by the network device or may be defined by a protocol.

[0452] In another example, if during the BFR process, the network device receives one or more negative Acknowledgement (NACK) messages of the Hybrid Automatic Repeat request-ACKnowledgement (HARQ-ACK) sent by the terminal device, it means that the quality of PDSCH transmitted using the current beam has deteriorated. At this time, the network device can send a first indication information to indicate the start of a first process to identify the deterioration of the beam quality in the current beam through the first process, so as to promptly know and respond to the deterioration of signal quality.

[0453] As described above, if the terminal device determines that the first start condition is satisfied, the terminal device may start the first process. Conversely, if the first start condition is not satisfied, the terminal device may not start the first process. The start condition of the first process may include at least one of the start conditions (1) to (9) above.

[0454] Specifically, if the first initiation condition is met, the terminal device may initiate the first process. More specifically, initiating the first process by the terminal device may include at least one of the following: requesting parameters for the first process from the network device (i.e., requesting the network device to configure the first process), receiving configuration information including parameters for the first process, receiving a first RS, measuring the first RS, detecting a first event, and initiating a counter for the first process. For details on initiating the counter for the first process, please refer to the relevant description below.

[0455] As described above, in another possible implementation of S21, the network device may initiate a BFR process. Further, after the BFR process is initiated, the network device may determine whether a first initiation condition is satisfied. For example, the first initiation condition includes at least one of the following: at least one of initiation condition (3), initiation condition (4), initiation condition (6), initiation condition (10), and initiation condition (11). The following mainly describes initiation condition (10) and initiation condition (11). For the specific contents of initiation condition (3), initiation condition (4), and initiation condition (6), please refer to the relevant description above.

[0456] Start condition (10): The network device does not receive a BFRQ.

[0457] Specifically, if the network device does not receive a BFRQ within the tenth time window, the network device may determine that the start condition (10) is met. If the network device receives a BFRQ within the tenth time window, it may determine that the start condition (10) is not met. For example, if the network device does not receive a BFRQ within the tenth time window, the network device may determine that the terminal device has not detected a beam failure event.

[0458] The start time of the tenth time window can be any of the following: the time when the network device configures the BFR process, the time when the first BFDRS is transmitted, or the time when the first NBIRS is transmitted. The duration of the tenth time window can be configured by the network device or defined by the protocol.

[0459] Start condition (11): Beam switching and / or cell switching during BFR is not completed.

[0460] Exemplarily, if the network device does not switch to the second new beam within the eleventh time window, the network device may determine that the start condition (11) is met. If the network device switches to the second new beam within the eleventh time window, it may be determined that the start condition (11) is not met. Wherein, the network device switching to the second new beam means that the network device starts to use the second new beam to communicate with the terminal device.

[0461] As another example, if the cell handover is not completed within the eleventh time window, the network device may determine that the start condition (11) is met. Specifically, if the network device does not provide services to the terminal device based on the second new cell within the eleventh time window, the network device may determine that the start condition (11) is met. If the network device starts to provide services to the terminal device based on the second new cell within the eleventh time window, the network device may determine that the start condition (11) is not met.

[0462] The starting time of the eleventh time window can be any of the following: the time when the network device configures the BFR process, the time when the first BFDRS is transmitted, the time when the first NBIRS is transmitted, the time when the BFRQ is transmitted (such as the time when the network device receives the BFRQ), or the time when the BFRR is transmitted (such as the time when the network device sends the BFRR). For example, the starting time of the eleventh time window can be the time when the beamFailureRecoveryTimer starts timing. The duration of the eleventh time window can be configured by the network device or defined by the protocol.

[0463] From the above, if the network device determines that the first start-up condition is met, the network device can start the first process. Conversely, if the network device determines that the first start-up condition is not met, the network device may not start the first process. Among them, the network device starting the first process may include at least one of the following: configuring the first process, sending the first RS, knowing or confirming that the terminal device starts the first process. In other words, if the first start-up condition is met, the network device may send parameters for the first process to the terminal device, or send configuration information including parameters for the first process to the terminal device. Alternatively, if the start-up condition of the first process is met, the network device may send the first RS to the terminal device. Alternatively, if the start-up condition of the first process is met, the network device knows or confirms that the terminal device starts the first process.

[0464] As described above, if the first starting condition is met, the terminal device may start the counter of the first process. The following is an exemplary description of starting the counter of the first process.

[0465] In one example, the counter of the first process may start counting from 0.

[0466] In another example, the counter of the first process may start counting from the maximum count value of the counter of the BFR process, wherein the maximum count value of the counter of the first process may be greater than the maximum count value of the counter of the BFR process.

[0467] For example, the counter for current beam measurement in the first process may start counting from the maximum count value of the counter for BFD in the BFR process, and the counter for new beam detection in the first process may start counting from the maximum count value of the counter for NBI in the BFR process.

[0468] For another example, for a serving cell, the counter used for current cell measurement in the first process may start counting from the maximum count value of the counter used for BFD corresponding to the serving cell. For a candidate cell, the counter used for new cell detection in the first process may start counting from the maximum count value of the counter used for NBI corresponding to the serving cell.

[0469] In yet another example, the counter of the first process may start counting from a current count value of the counter of the first process.

[0470] Specifically, the terminal device may start the first process before S22. Furthermore, before S22, the terminal device may stop the first process for some reason. When stopping the first process, the terminal device may save the current count value of the counter of the first process. Furthermore, during the BFR process, if the terminal device executes S22 and determines that the first start condition is met, the terminal device may restart the first process. In this case, when the terminal device restarts the first process, it may restart counting from the saved current count value of the counter.

[0471] In another example, the counter of the first process may start counting from the current count value of the counter of the BFR process. Specifically, when the first start condition is determined to be satisfied during the BFR process, the value of the counter of the BFR process may not have reached the maximum count value. In this case, the terminal device may use the current count value of the counter of the BFR process as the initial count value of the counter of the first process.

[0472] For example, after the BFR process is started, the value of the counter used for BFD does not reach the maximum count value within the first time window. If the terminal device can determine that the first start condition is met, the terminal device starts the first process, and the counter used for the current beam detection in the first process can start counting from the current count value of the counter used for BFD.

[0473] For another example, for a serving cell, the counter used for current cell measurement in the first process may start counting from the current count value of the counter used for BFD corresponding to the serving cell. For a candidate cell, the counter used for new cell detection in the first process may start counting from the current count value of the counter used for NBI corresponding to the serving cell.

[0474] Furthermore, when the value of the counter of the first process is increased by 1, the timer of the first process starts timing.

[0475] It should be noted that, for more details about the first counter of the first process and the timer of the first process, reference can be made to the above description of the first embodiment, which will not be repeated here.

[0476] In one example, if the first start condition is met, the BFR process can be stopped. For example, after the start condition of the first process is met, the terminal device may only execute the first process and no longer execute the BFR process. In this case, the start of the first process can be considered as the stop condition of the BFR process. For more information on stopping the BFR process, please refer to the relevant description of Example 5 below and will not be repeated here.

[0477] In another example, if the first initiation condition is met, the BFR process may continue to execute. Specifically, if the first initiation condition is met, the network device and / or terminal device may continue to execute the steps in the BFR process. That is, if the first initiation condition is met, the first process and the BFR process may be executed in parallel. Exemplarily, if the first initiation condition is met, the terminal device may execute the first process and the BFR process in parallel. For more details on the parallel execution of the first process and the BFR process, please refer to the relevant description of Examples 4 and 5 below and will not be repeated here.

[0478] As described above, in the second embodiment, the network device or terminal device can determine whether the first initiation condition is met based on the execution status of the BFR process during the BFR process, and trigger the initiation of the first process if the first initiation condition is met. In other words, in the second embodiment, the BFR process can trigger the first process. With this solution, the network device and / or terminal device can assist and supplement the BFR process by executing the first process. For example, even if no beam failure is detected, the network device and / or terminal device can promptly identify the deterioration of the terminal device's channel quality, thereby enabling timely beam management or beam switching.

[0479] For more details about the second embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0480] Example 3

[0481] Reference Figure 3 , Figure 3 It is a flow chart of the third communication method in the embodiment of the present application. Figure 3 The method shown can be applied to a communication device. Specifically, Figure 3 The method shown can be applied to a terminal device or a network device. Figure 3 In the illustrated scheme, the first process may trigger the BFR process. Figure 3 The illustrated method may include S31 and S32.

[0482] S31, start the first process;

[0483] S32 : In response to the start condition of the BFR process being met, start the BFR process.

[0484] In a possible implementation of S31, after the network device configures parameters for the first process for the terminal device, the terminal device may start the first process. More specifically, in S31, the terminal device may start the first process based on the configuration of the network device.

[0485] In another possible implementation of S21 , the network device may start the first process.

[0486] It should be noted that starting the first process in S31 is independent of the BFR process. Starting the first process in S31 may not depend on the BFR process.

[0487] For the specific content of starting the first process, please refer to the above description of the second embodiment, which will not be repeated here.

[0488] In this embodiment, after initiating the first process, the terminal device or network device may determine whether the initiation conditions for the BFR process are met. The initiation conditions for the BFR process are used to trigger the initiation of the BFR process. Specifically, if the initiation conditions for the BFR process are determined to be met, the terminal device or network device initiates the BFR process. Conversely, if the initiation conditions for the BFR process are determined not to be met, the terminal device or network device does not initiate the BFR process. Furthermore, if the BFR process is not initiated, the first process may continue.

[0489] The start-up condition of the BFR process is related to the first process. Specifically, the start-up condition of the BFR process may include at least one of the following start-up conditions (a) to (o).

[0490] Start condition (a): The terminal device detects the first event.

[0491] Specifically, if the terminal device detects the first event, it can be determined that the start condition (a) is satisfied. If the terminal device does not detect the first event, it can be determined that the start condition (a) is not satisfied.

[0492] More specifically, the terminal device detecting the first event may mean that the terminal device detects the first event within a thirteenth time window. If the terminal device detects the first event within the thirteenth time window, it may be determined that the start condition (a) is met. If the terminal device does not detect the first event within the thirteenth time window, it may be determined that the start condition (a) is not met.

[0493] Among them, the starting moment of the thirteenth time window can be any one of the following: the moment when the network device configures the first process, the transmission moment of the first first RS (such as the first first RS for current beam measurement, the first first RS for new beam detection). In this article, "the moment when the network device configures the first process" may refer to the transmission moment of the configuration information including the parameters for the first process (such as the moment when the network device sends the configuration information including the parameters for the first process, the moment when the terminal device receives the configuration information including the parameters for the first process). Among them, the duration of the thirteenth time window can be configured by the network device. Alternatively, the duration of the thirteenth time window can also be defined by the protocol.

[0494] It should be noted that the "transmission moment of the first first RS" in this article can be understood or described as at least one of the following: the starting moment of the terminal device receiving the first first RS", "the starting moment of the network device sending the first RS", "the starting moment of the terminal device measuring the first RS", and "the starting moment of the terminal device detecting the first event".

[0495] Start condition (b): The first information includes at least one of the following information: a detected first event, an outage beam, an outage cell, a first new beam, and a first new cell.

[0496] Specifically, in the first process, the terminal device may send first information to the network device. If the first information includes at least one of the following information: a detected first event, a failed beam, a failed cell, a first new beam, and a first new cell, it may be determined that the start condition (b) is met. Exemplarily, the terminal device may initiate the BFR process after sending the first information. If the first information sent by the terminal device to the network device does not include information about the detected handover event, the failed beam, the failed cell, the first new beam, and the first new cell, it may be determined that the start condition (b) is not met.

[0497] Start condition (c): the terminal device receives the second information.

[0498] Specifically, if the terminal device receives the second information, it can be determined that the start condition (c) is satisfied. If the terminal device does not receive the second information, it can be determined that the start condition (c) is not satisfied.

[0499] More specifically, the terminal device receiving the second information may mean that the terminal device receives the second information within a fourteenth time window. If the terminal device receives the second information within the fourteenth time window, it may be determined that the initiation condition (c) is met. If the terminal device does not receive the second information within the fourteenth time window, it may be determined that the initiation condition (c) is not met.

[0500] The starting time of the fourteenth time window may be any one of the following: the time when the network device configures the first process, the time when the first RS is transmitted, the time when the terminal device detects the first event, or the time when the first information is transmitted (e.g., the time when the terminal device sends the first information). The duration of the fourteenth time window may be configured by the network device. Alternatively, the duration of the fourteenth time window may be defined by a protocol.

[0501] Start condition (d): The first process is completed.

[0502] Specifically, if the first process is completed, it can be determined that the start condition (d) is met. The completion of the first process may refer to at least one of the following: the terminal device sends the first information, the network device receives the first information, the network device sends the second information, the terminal device receives the second information, the network device sends the trigger signaling, the terminal device receives the trigger signaling, the terminal device sends the response to the trigger signaling, the network device receives the response to the trigger signaling, the terminal device sends the beam report, the network device receives the beam report, the network device sends the update signaling, the terminal device receives the update signaling, the terminal device sends the response to the update signaling, the network device receives the response to the update signaling, the network device sends the indication signaling, the terminal device receives the indication signaling, the terminal device sends the response to the indication signaling, the network device receives the response to the indication signaling, the terminal device switches to the first new beam, the network device switches to the first new beam, and the terminal device switches to the first new cell. The trigger signaling is used to trigger at least one of beam measurement, beam reporting, beam training, and beam switching. The update signaling is used to update the first RS resource configured for the terminal device for current beam measurement and / or new beam detection. The indication signaling is used to indicate the new beam to be switched to.

[0503] More specifically, "the first process is completed" may mean "the first process is completed within the fifteenth time window." If the first process is completed within the fifteenth time window, the network device or terminal device may determine that the start condition (d) is met. If the first process is not completed within the fifteenth time window, the network device or terminal device may determine that the start condition (d) is not met.

[0504] Among them, the starting time of the fifteenth time window can be any one of the following: the time when the network device configures the first process, the transmission time of the first RS, the time when the terminal device detects the first event, the transmission time of the first information (such as the time when the terminal device sends the first information, the time when the network device receives the first information), the transmission time of the second information (such as the time when the terminal device receives the second information, the time when the network device sends the second information), the transmission time of the trigger signaling (such as the time when the network device sends the trigger signaling, the time when the terminal device receives the trigger signaling), the transmission time of the response to the trigger signaling (such as the time when the terminal device sends the response to the trigger signaling, the time when the network device receives the trigger signaling). The transmission time of the fifteenth time window may include the transmission time of the response to the update signaling (such as the moment when the network device sends the update signaling and the moment when the terminal device receives the update signaling), the transmission time of the response to the update signaling (such as the moment when the terminal device sends the response to the update signaling and the moment when the network device receives the response to the update signaling), the transmission time of the indication signaling (such as the moment when the network device sends the indication signaling and the moment when the terminal device receives the indication signaling), the transmission time of the response to the indication signaling (such as the moment when the terminal device sends the response to the indication signaling and the moment when the network device receives the response to the indication signaling), and the transmission time of the beam report (such as the moment when the terminal device sends the beam report and the moment when the network device receives the beam report). The duration of the fifteenth time window may be configured by the network device. Alternatively, the duration of the fifteenth time window may also be defined by the protocol.

[0505] Start condition (e): The terminal device receives second indication information, and the second indication information is used to indicate beam measurement or to trigger beam reporting or to indicate beam switching or to update the first RS.

[0506] Specifically, when the network device finds that the channel quality of the terminal device has deteriorated, it can send a second indication message to the terminal device to instruct the terminal device to improve the channel quality by beam measurement, beam reporting, beam switching, or updating the first RS used for current beam measurement and / or the first RS used for new beam detection. In this case, the terminal device can start the BFR process to respond to possible beam failure events in a timely manner.

[0507] In one example, the network device may send the second indication information to the terminal device after receiving the first information. That is, the network device sends the second information to the terminal device when receiving the first information.

[0508] In another example, if the first information does not include information about the first new beam or the first information includes indication information that the first new beam was not detected, the network device may send second indication information to the terminal device. Exemplarily, the network device sends the second indication information to update the first RS used for new beam detection. Furthermore, after the start condition of the BFR process is met, the BFR process and the first process may be executed in parallel, that is, the terminal device may search for a new beam through the BFR process and the first process executed in parallel, which is conducive to ensuring that a new beam is found or the beam quality of the new beam found, thereby ensuring the communication quality between the terminal device and the network device.

[0509] More specifically, the terminal device receiving the second indication information may mean that the terminal device receives the second indication information within the sixteenth time window. If the terminal device receives the second indication information within the sixteenth time window, it can be determined that the start condition (e) is met. If the terminal device does not receive the second indication information within the sixteenth time window, it can be determined that the start condition (e) is not met.

[0510] For the specific content of the sixteenth time window, reference may be made to the above description of the fifteenth time window, which will not be repeated here.

[0511] As described above, the second initiation condition may include at least one of the above-mentioned initiation conditions (a) to (e). Using the above solution, when the terminal device detects that the channel quality has deteriorated, the terminal device can further initiate the BFR process and perform beam failure detection in advance, thereby timely detecting beam failure events and facilitating communication quality assurance.

[0512] Start condition (f): The terminal device does not detect the first event in the first process.

[0513] Specifically, if the terminal device does not detect the first event within the seventeenth time window, it can be determined that the start condition (f) is met. If the terminal device detects an event of the first process within the seventeenth time window, it can be determined that the start condition (f) is not met.

[0514] The starting time of the seventeenth time window may be any one of the following: the time when the network device configures the first process, or the time when the first RS is transmitted. The duration of the seventeenth time window may be configured by the network device. Alternatively, the duration of the seventeenth time window may be defined by a protocol.

[0515] Starting condition (g): the first information does not include information of the first new beam.

[0516] Specifically, if the first information sent by the terminal device or the first information to be sent does not include information about the first new beam, it can be determined that the start condition (g) is met. Exemplarily, if the first information does not include information about the first new beam, it can be understood that the terminal device did not identify the first new beam in the first process. Conversely, if the first information includes information about the first new beam, it can be determined that the start condition (g) is not met. The first new beam may include: a new beam within the serving cell and / or a new beam within the alternative cell.

[0517] Exemplarily, if the first information does not include information about the first new beam in the current serving cell, that is, the terminal device does not identify the first new beam in the current serving cell, it can be determined that the start condition (g) is met.

[0518] As another example, if the request information does not include information about the first new beam in the alternative cell, that is, the terminal device does not identify the first new beam in the alternative cell, it can be determined that the start condition (g) is met.

[0519] As another example, if the first information includes neither the information of the first new beam in the serving cell nor the information of the first new beam in the alternative cell, that is, the terminal device neither identifies the first new beam in the new cell nor identifies the first new beam on the alternative cell, it can be determined that the start condition (g) is met.

[0520] In one example, if the first information to be sent does not include information about the first new beam, the terminal device may initiate a BFR process and cancel sending the first information.

[0521] Start condition (h): The first information does not include information of the first new cell.

[0522] Specifically, if the first information sent by the terminal device or the first information to be sent does not include information about the first new cell, it can be determined that the start condition (h) is met. Conversely, if the first information includes information about the first new cell, it can be determined that the start condition (h) is not met.

[0523] Start condition (i): the terminal device does not receive the second information in the first process.

[0524] Specifically, if the terminal device does not receive the second information within the eighteenth time window, it can be determined that the start condition (i) is met. If the terminal device receives the second information within the eighteenth time window, it can be determined that the start condition (i) is not met.

[0525] The starting time of the eighteenth time window may be any one of the following: the time when the network device configures the first process, the time when the first first RS is transmitted, the time when the terminal device detects an event of the first process, or the time when the request information is transmitted (such as the time when the terminal device sends the first information). The duration of the eighteenth time window may be configured by the network device. Alternatively, the duration of the eighteenth time window may also be defined by a protocol.

[0526] For example, if the terminal device does not receive the second information within a preset time period (i.e., the duration of the eighteenth time window) after sending the first information, then the initiation condition (i) is met. The failure of the terminal device to receive the second information may be due to a failure to send the first information or a failure to receive the second information due to deterioration of channel quality. In this case, initiating the BFR process can promptly restore communication between the terminal device and the network device.

[0527] Start condition (j): The first process is not completed.

[0528] Specifically, if the first process is not completed within the nineteenth time window, it can be determined that the start condition (j) is satisfied. In other words, if the first process is not successfully completed within the nineteenth time window, it can be determined that the start condition (j) is satisfied. If the first process is successfully completed within the nineteenth time window, it can be determined that the start condition (j) is not satisfied.

[0529] The specific content of the nineteenth time window can refer to the above description of the fifteenth time window, which will not be repeated here. The specific content of the completion of the first process can refer to the above description, which will not be repeated here.

[0530] Start condition (k): The terminal device has not completed beam switching and / or cell switching in the first process.

[0531] In one example, if the terminal device does not switch to the first new beam within the twentieth time window, it may be determined that the start condition (k) is met. If the terminal device switches to the first new beam within the twentieth time window, it may be determined that the start condition (k) is not met.

[0532] In another example, if the terminal device does not switch to the first new cell within the twentieth time window, it may be determined that the start condition (k) is met. If the terminal device switches to the first new cell within the twentieth time window, it may be determined that the start condition (k) is not met.

[0533] In another example, if the terminal device neither switches to the first new beam nor to the first new cell within the twentieth time window, it may be determined that the start condition (k) is met. If the terminal device switches to the first new beam and to the first new cell within the twentieth time window, it may be determined that the start condition (k) is not met.

[0534] For the specific content of the twentieth time window, reference may be made to the above description of the fifteenth time window, which will not be repeated here.

[0535] Start condition (1): The terminal device receives the third indication information, and the third indication information is used to indicate the start of the BFR process.

[0536] Specifically, during the execution of the first process, the network device may send third indication information to the terminal device. If the terminal device receives the third indication information after the first process is started, it may be determined that the start condition (1) is met. If the terminal device does not receive the third indication information after the first process is started, the start condition (1) is not met.

[0537] More specifically, if the terminal device receives the third indication information within the twenty-first time window, it can be determined that the start condition (l) is met. The starting moment of the twenty-first time window can be any one of the following: the moment when the network device configures the first process, the transmission moment of the first RS, the moment when the terminal device detects the first event, the transmission moment of the first information (such as the moment when the terminal device sends the first information), the transmission moment of the second information (such as the moment when the terminal device receives the second information), the transmission moment of the trigger signaling, the transmission moment of the response to the trigger signaling, the transmission moment of the beam report, the transmission moment of the update signaling, the transmission moment of the response to the update signaling, the transmission moment of the indication signaling, and the transmission moment of the response to the indication signaling. The duration of the twenty-first time window can be configured by the network device. Alternatively, the duration of the twenty-first time window can also be defined by the protocol.

[0538] In a specific implementation, whether to send the third indication information and the timing of sending the third indication information may depend on the autonomous decision of the network device.

[0539] In one example, if the network device receives the first information, the network device may send third indication information to the terminal device. Specifically, if the network device receives the first information within a 22nd time window, the network device may send the third indication information to the terminal device. The start time of the 22nd time window may be the time when the network device configures the first process. The duration of the 22nd time window may be configured by the network device or defined by a protocol.

[0540] In another example, if the network device does not receive the first information within the twenty-third time window, the network device may send third indication information to the terminal device. If the network device receives the first information within the twenty-third time window, the network device may not need to send the third indication information to the terminal device. The start time of the twenty-third time window may be the time when the network device configures the first process. The duration of the twenty-third time window may be configured by the network device or defined by a protocol.

[0541] As described above, in S32, if the terminal device determines that the initiation conditions for the BFR process are met, the terminal device may initiate the BFR process. Conversely, if the initiation conditions for the BFR process are not met, the terminal device may not initiate the BFR process. The initiation conditions for the BFR process may include at least one of the initiation conditions (a) to (1) described above. For details on the initiation of the BFR process by the terminal device, please refer to the relevant description in the second embodiment above.

[0542] As described above, in another possible implementation of S31, the network device may initiate the first process. Furthermore, after the first process is initiated, the network device may determine whether the initiation conditions for the BFR process are met. The initiation conditions for the BFR process may include at least one of the following: initiation condition (b), initiation condition (d), initiation condition (m), initiation condition (g), initiation condition (h), initiation condition (n), initiation condition (j), and initiation condition (o). Initiation condition (m), initiation condition (n), and initiation condition (o) are described in detail below. For the specific details of the other initiation conditions, please refer to the relevant descriptions above and will not be repeated here.

[0543] Start condition (m): The network device receives the first information.

[0544] Specifically, after the first process is started, if the terminal device sends the first information to the network device, that is, if the network device receives the first information, then the start condition (m) is met. Exemplarily, the network device can start the BFR process after receiving the first information.

[0545] More specifically, if the network device receives the first information within the 24th time window, it determines that the start condition (m) is met. If the network device does not receive the first information within the 24th time window, it may determine that the start condition (m) is not met.

[0546] The start time of the 24th time window may be any one of the following: the time when the network device configures the first process, or the time when the first RS is transmitted. The duration of the 24th time window may be configured by the network device, or may be defined by a protocol.

[0547] Start condition (n): the network device does not receive the first information.

[0548] Specifically, if the network device does not receive the first information within the 25th time window, the network device may determine that the start condition (n) is met. If the network device receives the first information within the 25th time window, the network device may determine that the start condition (n) is not met.

[0549] The start time of the 25th time window may be any of the following: the time when the network device configures the first process, the time when the first RS is transmitted, and the duration of the 25th time window may be configured by the network device or defined by a protocol.

[0550] Start condition (o): beam switching and / or cell switching in the first process is not completed.

[0551] Exemplarily, if the network device does not switch to the first new beam within the twenty-sixth time window, it can be determined that the start condition (o) is met. If the network device switches to the first new beam within the twenty-sixth time window, it can be determined that the start condition (o) is not met. Wherein, the network device switching to the first new beam means that the network device begins to use the first new beam to communicate with the terminal device.

[0552] Exemplarily, if the cell handover is not completed within the twenty-sixth time window, the network device may determine that the start condition (o) is met. Specifically, if the network device does not provide services to the terminal device based on the first new cell within the twenty-sixth time window, the network device may determine that the start condition (o) is met. If the network device starts to provide services to the terminal device based on the first new cell within the twenty-sixth time window, the network device may determine that the start condition (o) is not met.

[0553] Among them, the twenty-sixth time window can be any one of the following: the moment when the network device configures the first process, the transmission moment of the first RS, the transmission moment of the first information (such as the moment when the network device receives the first information), the transmission moment of the second information (such as the moment when the network device sends the second information), the transmission moment of the trigger signaling, the transmission moment of the response to the trigger signaling, the transmission moment of the beam report, the transmission moment of the update signaling, the transmission moment of the response to the update signaling, the transmission moment of the indication signaling, and the transmission moment of the response to the indication signaling. Among them, the duration of the twenty-sixth time window can be configured by the network device. Alternatively, the duration of the twenty-sixth time window can also be defined by the protocol.

[0554] As described above, if the network device determines that the conditions for initiating the BFR process are met, the network device may initiate the BFR process. Conversely, if the conditions for initiating the BFR process are not met, the network device may not initiate the BFR process. For details on how the network device initiates the BFR process, please refer to the relevant description in Example 2 above.

[0555] In this embodiment, after the BFR process initiation conditions are met, the terminal device may initiate a BFR process counter. The BFR process counter may include a BFD counter and / or an NBI counter. The following provides an exemplary description of the BFR process initiation counter.

[0556] In one example, after the start condition of the BFR process is met, the counter of the BFR process may start counting from 0.

[0557] In another example, after the start condition of the BFR process is satisfied, the counter of the BFR process may start counting from the maximum count value of the counter of the first process.

[0558] Specifically, the counter for BFD may start counting from the maximum count value of the counter used for current beam measurement in the first process. More specifically, if there are multiple current beams, there may be multiple counters used for current beam measurement in the first process. In this case, the initial count value of the counter for BFD may be the minimum or maximum value of the maximum count values ​​of the multiple counters used for current beam measurement in the first process. Alternatively, the counter for BFD may start counting from the maximum count value of the counter used for current cell measurement in the first process configured on the same cell.

[0559] The counter for NBI in the BFR process may start counting from the maximum count value of the counter used for new beam detection in the first process. Alternatively, the counter for NBI may start counting from the maximum count value of the counter used for new cell measurement configured on the same cell.

[0560] The maximum count value of the counter used for BFD may be greater than the maximum count value of the counter used for current beam measurement or the counter used for current cell measurement in the first process. The maximum count value of the counter used for NBI in the BFR process may be greater than the maximum count value of the counter used for new beam detection or the counter used for new cell detection in the first process.

[0561] In yet another example, after the start condition of the BFR process is satisfied, the counter of the BFR process may start counting from a current count value of the counter of the BFR process.

[0562] Specifically, the terminal device may initiate the BFR process before S32. Furthermore, before S32, the terminal device may stop the BFR process for some reason. When stopping the BFR process, the terminal device may save the current count value of the BFR process counter. Furthermore, during the first process, the terminal device executes S32. If it determines that the start conditions for the BFR process are met, the terminal device may restart the BFR process. In this case, when the terminal device restarts the BFR process, it may restart counting from the saved count value. More specifically, the BFD counter and / or the NBI counter may start counting from their saved current count values.

[0563] In another example, the counter of the BFR process may start counting from the current count value of the counter of the first process. Specifically, when the first process determines that the start condition of the BFR process is met, the value of the counter of the first process may not have reached the maximum count value. In this case, the terminal device may use the current count value of the counter of the first process as the initial count value of the counter of the BFR process.

[0564] More specifically, the counter for BFD can start counting from the current count value of the counter used for current beam measurement in the first process. If there are multiple current beams, there can be multiple counters used for current beam measurement in the first process. In this case, the initial count value of the counter for BFD can be the minimum or maximum value of the current count values ​​of the multiple counters used for current beam measurement in the first process. Alternatively, the counter for BFD can start counting from the current count value of the counter used for current cell measurement in the first process configured on the same cell.

[0565] The counter for NBI in the BFR process may start counting from the current count value of the counter used for new beam detection in the first process. Alternatively, the counter for NBI may start counting from the current count value of the counter used for new cell measurement configured on the same cell.

[0566] In one example, if the start conditions for the BFR process are met, the first process may be stopped. For example, if it is determined that the start conditions for the BFR process are met, the terminal device and / or network device may only execute the BFR process and no longer execute the first process. In this case, the start of the BFR process can be considered a stop condition for the first process. For more information on stopping the first process, please refer to the relevant description of Example 4 below and will not be repeated here.

[0567] In another example, if the initiation conditions of the BFR process are met, the first process may continue to be executed. That is, if the initiation conditions of the BFR process are met, the first process and the BFR process may be executed in parallel. For example, if it is determined that the initiation conditions of the BFR process are met, the terminal device and / or network device may execute the first process and the BFR process in parallel. For more details on the parallel execution of the first process and the BFR process, please refer to the relevant descriptions of Examples 4 and 5 below and will not be repeated here.

[0568] As described above, in the third embodiment, the network device and / or terminal device can determine whether the BFR process initiation conditions are met based on the execution status of the first process during the execution of the first process, and initiate the BFR process if the BFR process initiation conditions are met. In other words, in the third embodiment, the first process can trigger the BFR process. With this approach, the terminal device can assist and supplement the first process by executing the BFR process, thereby promptly identifying terminal device signal interruptions and restoring communication between the terminal device and the network device.

[0569] For more details about the third embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0570] Example 4

[0571] Reference Figure 4 , Figure 4 It is a flow chart of the fourth communication method in the embodiment of the present application. Figure 4 The method shown can be applied to a communication device. Specifically, Figure 4 The method shown can be applied to a terminal device or a network device. Figure 4 In the illustrated scheme, while the first process and the BFR process are being executed in parallel, the BFR process may stop the first process. Figure 4 The illustrated method may include S41 , S42 , and S43 .

[0572] S41, starting the first process;

[0573] S42, start the BFR process;

[0574] S43: In response to the first stopping condition being met, stop the first process.

[0575] This embodiment does not limit the order in which S41 and S42 are executed. For example, initiating the first process and the BFR process on a terminal device, the terminal device may initiate the first process first, followed by the BFR process. Alternatively, the terminal device may initiate the BFR process first, followed by the first process. Furthermore, the terminal device may initiate the BFR process and the first process simultaneously.

[0576] In one example, the first process and the BFR process in this embodiment are started independently of each other. For example, the terminal device may start the first process after the network device configures the first process, and start the BFR process after the network device configures the BFR process.

[0577] In another example, the first process in S41 may be triggered by a BFR process. After the BFR process triggers the first process, the terminal device executes both the BFR process and the first process. For more details about how the BFR process triggers the first process, refer to the above description of Example 2 and are not repeated here.

[0578] In another example, the BFR process in S42 may be triggered by the first process. After the first process triggers the BFR process, the terminal device executes both the first process and the BFR process. For more details about how the first process triggers the BFR process, refer to the above description of Example 3 and are not repeated here.

[0579] In the solution of this embodiment, while the first process and the BFR process are being executed in parallel, the terminal device or network device may determine whether a first stop condition is met. The first stop condition is used to trigger the termination of the first process. That is, if the first stop condition is determined to be met, the terminal device or network device may terminate the first process. If the first stop condition is determined not to be met, the terminal device or network device may continue to execute the first process. Furthermore, if the first stop condition is determined to be met, the BFR process may continue to execute.

[0580] The first stop condition is described in detail below. The first stop condition may include at least one of the following stop conditions (1) to (9).

[0581] Stop condition (1): The terminal device detects a beam failure event.

[0582] Specifically, if the terminal device detects a beam failure event, it may be determined that the stop condition (1) is satisfied. If the terminal device does not detect a beam failure event, it may be determined that the stop condition (1) is not satisfied.

[0583] More specifically, if the terminal device detects a beam failure event within the twenty-seventh time window, it may be determined that the stop condition (1) is satisfied. If the terminal device does not detect a beam failure event within the twenty-seventh time window, it may be determined that the stop condition (1) is not satisfied.

[0584] The starting time of the 27th time window can be any of the following: the time when the network device configures the BFR process, the time when the first BFDRS is transmitted, the time when the first NBIRS is transmitted, or the time when the terminal device identifies the second new beam. The duration of the 27th time window can be configured by the network device. For example, the duration of the 27th time window can be the duration of the beamFailureRecoveryTimer. Alternatively, the duration of the 27th time window can also be defined by the protocol.

[0585] Stop condition (2): BFRQ is reported.

[0586] In one example, if the terminal device sends a BFRQ to the network device, it can be determined that the stop condition (2) is satisfied. If the terminal device does not send a BFRQ to the network device, it can be determined that the stop condition (2) is not satisfied. More specifically, if the terminal device sends a BFRQ to the network device within the twenty-eighth time window, it can be determined that the stop condition (2) is satisfied. If the terminal device does not send a BFRQ to the network device within the twenty-eighth time window, it can be determined that the stop condition (2) is not satisfied.

[0587] Among them, the starting time of the 28th time window can be any one of the following: the time when the network device configures the BFR process, the transmission time of the first BFDRS, the transmission time of the first NBIRS, the time when the terminal device detects the beam failure event, and the time when the terminal device recognizes the second new beam.

[0588] In another example, if the network device receives a BFRQ, it can be determined that the stop condition (2) is satisfied. If the network device does not receive the BFRQ, it can be determined that the stop condition (2) is not satisfied. More specifically, if the network device receives a BFRQ within the twenty-ninth time window, it can be determined that the stop condition (2) is satisfied. If the network device does not receive a BFRQ within the twenty-ninth time window, it can be determined that the stop condition (2) is not satisfied. The starting time of the twenty-ninth time window can be any one of the following: the time when the network device configures the BFR process, the time when the first BFDRS is transmitted, and the time when the first NBIRS is transmitted.

[0589] The duration of the 28th time window and / or the 29th time window may be configured by the network device. For example, the duration of the 28th time window and / or the 29th time window may be the duration of beamFailureRecoveryTimer. Alternatively, the duration of the 28th time window and / or the 29th time window may be defined by a protocol.

[0590] Stop condition (3): The BFRQ includes information of at least one of the following: failed beam, failed cell, second new beam, second new cell.

[0591] Specifically, if the BFRQ sent by the terminal device includes at least one of the following information: failed beam, failed cell, new beam, and new cell, it can be determined that the stop condition (3) is met. If the BFRQ does not include at least one of the following information: failed beam, failed cell, new beam, and new cell, it can be determined that the stop condition (3) is not met.

[0592] The failed beam may refer to a beam used to determine a beam failure event, and the failed cell may be a cell to which the failed beam belongs. The second new beam may include a second new beam in a current serving cell and a second new beam in an alternative cell.

[0593] Stop condition (4): The terminal device receives a BFRR.

[0594] Specifically, if the terminal device receives the BFRR, it can be determined that the stop condition (4) is satisfied. If the terminal device does not receive the BFRR, it can be determined that the stop condition (4) is not satisfied.

[0595] More specifically, if the terminal device receives a BFRR within the 30th time window, it can be determined that the stop condition (4) is met. If the terminal device does not receive a BFRR within the 30th time window, it can be determined that the stop condition (4) is not met. The starting time of the 30th time window can be any one of the following: the time when the network device configures the BFR process, the transmission time of the first BFDRS, the transmission time of the first NBIRS, the time when the terminal device detects a beam failure event, the time when the terminal device identifies the second new beam, the transmission time of the BFRQ (such as the time when the terminal device sends the BFRQ). The duration of the 30th time window can be configured by the network device. For example, the duration of the 30th time window can be the duration of the beamFailureRecoveryTimer. Alternatively, the duration of the 30th time window can also be defined by the protocol.

[0596] Stop condition (5): The BFR process is completed.

[0597] Specifically, if the BFR process is completed, it can be determined that the stop condition (5) is satisfied. If the BFR process is not completed, it can be determined that the stop condition (5) is not satisfied.

[0598] More specifically, “BFR process completion” may mean “BFR process completion within the 31st time window.” If the BFR process is completed within the 31st time window, the network device or terminal device may determine that the stop condition (5) is satisfied. If the BFR process is not completed within the 31st time window, the network device or terminal device may determine that the stop condition (5) is not satisfied.

[0599] Among them, the starting moment of the thirty-first time window can be any one of the following: the moment when the network device configures the BFR process, the transmission moment of the first BFDRS, the transmission moment of the first NBIRS, the moment when the terminal device detects the beam failure event, the moment when the terminal device identifies the second new beam, the transmission moment of BFRQ (such as the moment when the terminal device sends BFRQ, the moment when the network device receives BFRQ), the transmission moment of BFRR (such as the moment when the terminal device receives BFRR, the moment when the network device sends BFRR). The duration of the thirty-first time window can be configured by the network device. For example, the duration of the thirty-first time window can be the duration of beamFailureRecoveryTimer. Alternatively, the duration of the thirty-first time window can also be defined by the protocol. For the relevant content about completing BFR, please refer to the relevant description in the above embodiment 2, which will not be repeated here.

[0600] Stop condition (6): The terminal device recognizes the second new beam.

[0601] Specifically, after the terminal device initiates the BFR process, if the terminal device identifies the second new beam by performing the step of identifying the new beam, it can be determined that the stop condition (6) is met. If the terminal device does not identify the second new beam, it can be determined that the stop condition (6) is not met.

[0602] More specifically, if the terminal device identifies the second new beam within the thirty-second time window, it can be determined that the stop condition (6) is met. If the terminal device does not identify the second new beam within the thirty-second time window, it can be determined that the stop condition (6) is not met. The starting time of the thirty-second time window can be any one of the following: the moment when the network device configures the BFR process, the transmission moment of the first BFDRS, the transmission moment of the first NBIRS, and the moment when the terminal device detects a beam failure event. The duration of the thirty-second time window can be configured by the network device. For example, the duration of the thirty-second time window can be the duration of the beamFailureRecoveryTimer. Alternatively, the duration of the thirty-second time window can also be defined by the protocol.

[0603] Stop condition (7): The terminal device detects a second new cell.

[0604] Specifically, if the terminal device detects a second new cell during BFR, it may be determined that stop condition (7) is satisfied. If the terminal device does not detect a second new cell during BFR, it may be determined that stop condition (7) is not satisfied. In other words, if the terminal device identifies a second new beam on a non-serving cell, it may be determined that stop condition (7) is satisfied.

[0605] More specifically, if the terminal device identifies the second new cell within the thirty-third time window, it can be determined that the stop condition (7) is met. If the terminal device does not identify the second new cell within the thirty-third time window, it can be determined that the stop condition (7) is not met. The starting time of the thirty-third time window can be any one of the following: the time when the network device configures the BFR process, the transmission time of the first BFDRS, the transmission time of the first NBIRS, and the time when the terminal device detects a beam failure event. The duration of the thirty-third time window can be configured by the network device. Alternatively, the duration of the thirty-third time window can also be defined by the protocol.

[0606] Stop condition (8): beam switching and / or cell switching during the BFR process is completed.

[0607] Exemplarily, if the terminal device switches to the second new beam and / or switches to the second new cell during the BFR process, it can be determined that the stop condition (8) is met. If the terminal device does not switch to the second new beam and / or switches to the second new cell during the BFR process, it can be determined that the stop condition (8) is not met.

[0608] Exemplarily, if the network device switches to the second new beam during the BFR process, it can be determined that the stop condition (8) is satisfied. If the network device does not switch to the second new beam, it can be determined that the stop condition (8) is not satisfied. The network device switching to the second new beam means that the network device starts to communicate with the terminal device using the second new beam.

[0609] Exemplarily, if the network device completes the cell handover during the BFR process, the network device may determine that the stop condition (8) is satisfied. Specifically, if the network device starts to provide services to the terminal device based on the second new cell during the BFR process, the network device may determine that the stop condition (8) is satisfied.

[0610] In a specific implementation, the completion of beam switching and / or cell switching in the BFR process may refer to the completion of beam switching and / or cell switching within the thirty-fourth time window. The starting time of the thirty-fourth time window may be any one of the following: the moment when the network device configures the BFR process, the transmission moment of the first BFDRS, the transmission moment of the first NBIRS, the moment when the terminal device detects a beam failure event, the moment when the terminal device identifies the second new beam, the moment when the terminal device detects the second new cell, the transmission moment of BFRQ (such as the moment when the terminal device sends BFRQ, the moment when the network device receives BFRQ), the transmission moment of BFRR (such as the moment when the terminal device receives BFRR, the moment when the network device sends BFRR). The duration of the thirty-fourth time window may be configured by the network device. Alternatively, the duration of the thirty-fourth time window may also be defined by the protocol.

[0611] Stop condition (9): The terminal device receives fourth indication information, and the fourth indication information is used to instruct to stop the first process.

[0612] Specifically, if the terminal device receives the fourth indication information, it can be determined that the stop condition (9) is met. If the terminal device does not receive the fourth indication information, the stop condition (9) is not met.

[0613] More specifically, if the terminal device receives the fourth indication information within the thirty-sixth time window, it can be determined that the stop condition (9) is met. The starting time of the thirty-sixth time window can be any one of the following: the time when the network device configures the BFR process, the transmission time of the first BFDRS, the transmission time of the first NBIRS, the time when the terminal device detects a beam failure event, the time when the terminal device identifies the second new beam, the time when the terminal device identifies the second new cell, the transmission time of BFRQ (such as the time when the terminal device sends BFRQ), the transmission time of BFRR (such as the time when the terminal device receives BFRR). The duration of the thirty-sixth time window can be configured by the network device. Alternatively, the duration of the thirty-sixth time window can also be defined by the protocol.

[0614] In a specific implementation, whether to send the fourth indication information and the timing of sending the fourth indication information may depend on the autonomous decision of the network device.

[0615] In one example, if the network device receives a BFRQ and / or the BFRQ includes information about the second new beam, the network device may send fourth indication information to the terminal device. Specifically, if the network device receives a BFRQ and / or the BFRQ includes information about the second new beam within the thirty-seventh time window, the network device may send fourth indication information to the terminal device. The starting time of the thirty-seventh time window may be the time when the network device configures the BFR process. The duration of the thirty-seventh time window may be configured by the network device. Alternatively, the duration of the thirty-seventh time window may also be defined by a protocol.

[0616] As described above, the first stop condition may include at least one of the stop conditions (1) to (9) above. If the terminal device determines that the first stop condition is satisfied, the terminal device may stop the first process. Alternatively, if the network device determines that the first stop condition is satisfied, the network device may stop the first process. Conversely, if the first stop condition is not satisfied, the first process may continue to be executed. Further, if the first stop condition is satisfied, the BFR process may continue to be executed.

[0617] Exemplarily, if the first stop condition is met, the terminal device may reset the counter of the first process to zero and / or restart the timer of the first process. In other words, the terminal device stopping the first process may mean: resetting the counter of the first process to zero and / or restarting the timer of the first process.

[0618] As described above, the counters of the first process may include at least one of the following: a counter for current beam measurement, a counter for current cell measurement, a counter for new beam detection, and a counter for new cell detection. Exemplarily, if the first stop condition is met, the counters of each first process may be reset to zero.

[0619] For the specific contents of the counter of the first process and the timer of the first process, please refer to the above description and will not be repeated here.

[0620] Exemplarily, if the stop condition of the first process is satisfied, the terminal device may stop sending the first information. In other words, if the stop condition of the first process is satisfied, the terminal device may cancel sending the first information.

[0621] Exemplarily, if the stop condition of the first process is met, the terminal device may stop measuring the first RS resources used for current beam measurement and the first RS resources used for new beam detection.

[0622] Exemplarily, if the stop condition of the first process is met, the network device may stop sending the first RS for current beam measurement and / or the first RS for new beam detection.

[0623] Exemplarily, if the stop condition of the first process is met, the terminal device may stop receiving the first RS for current beam measurement and / or the first RS for new beam detection.

[0624] For example, if the stop condition of the first process is met, the terminal device can pause the first process that has been started. In a specific implementation, the conditions for restarting the suspended first process can refer to the relevant description of Example 2 above and will not be repeated here. In other words, when the first start condition is met, the suspended first process in this embodiment can continue to be executed.

[0625] Exemplarily, if the first stop condition is met, the terminal device or network device may consider the first process to be completed. In other words, if the stop condition of the first process is met, the terminal device or network device may end the first process started this time.

[0626] As described above, in the fourth embodiment, after the network device configures the terminal device to execute the BFR process and the first process, the network device or the terminal device may stop the first process if a beam failure event is detected and / or a second new beam is identified during the BFR process. With this solution, since the terminal device has already detected a signal interruption through the BFR process, there is no need to detect deterioration in the terminal device's channel quality through the first process. Alternatively, if a new beam has already been identified through the BFR process, there is no need to search for a new beam through the first process. Therefore, in this solution, while the BFR process and the first process are being executed in parallel, stopping the first process is triggered based on the execution of the BFR process, which helps save power consumption in the terminal device.

[0627] For more details about the fourth embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0628] Example 5

[0629] Reference Figure 5 , Figure 5 It is a flow chart of the fifth communication method in the embodiment of the present application. Figure 5 The method shown can be applied to a communication device. Specifically, Figure 5 The method shown can be applied to a terminal device or a network device. Figure 5 In the illustrated scheme, during the process in which the first process and the BFR process are performed in parallel, the first process may stop the BFR process. Figure 5 The illustrated method may include S51 , S52 , and S53 .

[0630] S51, starting the first process;

[0631] S52, start the BFR process;

[0632] S53 , in response to the stopping condition of the BFR process being met, stopping the BFR process.

[0633] This embodiment does not limit the order in which S51 and S52 are executed. For example, initiating the first process and the BFR process on a terminal device, the terminal device may initiate the first process first, followed by the BFR process. Alternatively, the terminal device may initiate the BFR process first, followed by the first process. Furthermore, the terminal device may initiate the BFR process and the first process simultaneously.

[0634] For the relevant descriptions of steps S51 and S52, reference can be made to the relevant descriptions of steps S41 and S42 above, which will not be repeated here.

[0635] In the solution of this embodiment, while the first process and the BFR process are being executed in parallel, the terminal device or network device may determine whether a stop condition for the BFR process is met. The stop condition for the BFR process is used to trigger the termination of the BFR process. Specifically, if the stop condition for the BFR process is determined to be met, the terminal device or network device may terminate the BFR process. If the stop condition for the BFR process is determined not to be met, the terminal device or network device may continue to execute the BFR process. Furthermore, if the stop condition for the BFR process is determined to be met, the first process may continue to be executed.

[0636] The stop condition of the BFR process is described in detail below. The stop condition of the BFR process may include at least one of stop conditions (a) to (j).

[0637] Stop condition (a): The terminal device detects the first event.

[0638] Specifically, if the terminal device detects the first event, it may be determined that the stop condition (a) is satisfied. If the terminal device does not detect the first event, it may be determined that the stop condition (a) is not satisfied.

[0639] More specifically, if the terminal device detects the first event within the thirty-eighth time window, it can be determined that the stop condition (a) is met. If the terminal device does not detect the first event within the thirty-eighth time window, it can be determined that the stop condition (a) is not met.

[0640] The starting time of the 38th time window may be any one of the following: the time when the network device configures the first process, or the time when the first RS is transmitted. The duration of the 38th time window may be configured by the network device. Alternatively, the duration of the 38th time window may be defined by a protocol.

[0641] Stop condition (b): the first information is reported.

[0642] In one example, after the terminal device starts the first process, if the terminal device sends the second information to the network device, then the stop condition (b) is satisfied. If the terminal device does not send the first information to the network device, then the stop condition (b) is not satisfied.

[0643] More specifically, if the terminal device sends the first information within the thirty-ninth time window, the stop condition (b) is satisfied. If the terminal device does not send the first information to the network device within the thirty-ninth time window, it can be determined that the stop condition (b) is not satisfied.

[0644] The start time of the 39th time window may be any one of the following: the time when the network device configures the first process, the time when the first RS is transmitted, or the time when the terminal device detects the first event. The duration of the 39th time window may be configured by the network device. Alternatively, the duration of the 39th time window may be defined by a protocol.

[0645] In another example, if the network device receives the first information, it can be determined that the stop condition (b) is met. If the network device does not receive the first information, it can be determined that the stop condition (b) is not met. More specifically, if the network device receives the first information within the 40th time window, it can be determined that the stop condition (b) is met. If the network device does not receive the first information within the 40th time window, it can be determined that the stop condition (b) is not met. The starting time of the 40th time window can be any one of the following: the time when the network device configures the first process, the transmission time of the first first RS. The duration of the 40th time window can be configured by the network device. Alternatively, the duration of the 40th time window can also be defined by the protocol.

[0646] Stop condition (c): The first information includes at least one of the following information: a detected first event, an outage beam, an outage cell, a first new beam, and a first new cell.

[0647] Specifically, if the first information sent by the terminal device to the network device includes at least one of the following information: a detected first event, a failed beam, a failed cell, a first new beam, and a first new cell, then it can be determined that the stop condition (c) is met. If the first information sent by the terminal device to the network device does not include at least one of the following information: a detected first event, a failed beam, a failed cell, a first new beam, and a first new cell, then it can be determined that the stop condition (c) is not met.

[0648] Stop condition (d): The terminal device receives the second information.

[0649] Specifically, if the terminal device receives the second information, it can be determined that the stop condition (d) is satisfied. If the terminal device does not receive the second information, it can be determined that the stop condition (d) is not satisfied.

[0650] More specifically, if the terminal device receives the second information in the 41st time window, it can be determined that the stop condition (d) is met. If the terminal device does not receive the second information in the 41st time window, it can be determined that the stop condition (d) is not met.

[0651] The starting time of the forty-first time window may be any one of the following: the time when the network device configures the first process, the time when the first first RS is transmitted, the time when the terminal device detects the first event, or the time when the first information is transmitted (e.g., the time when the terminal device sends the first information). The duration of the forty-first time window may be configured by the network device. Alternatively, the duration of the forty-first time window may also be defined by a protocol.

[0652] Stop condition (e): The first process is completed.

[0653] Specifically, if the first process is completed, it can be determined that the stop condition (e) is satisfied. If the first process is not completed, it can be determined that the stop condition (e) is not satisfied. For the specific content of completing the first process, please refer to the relevant description above and will not be repeated here.

[0654] More specifically, "the first process is completed" may mean "the first process is completed within the 42nd time window." If the first process is completed within the 42nd time window, the network device or terminal device may determine that the stop condition (e) is satisfied. If the first process is not completed within the 42nd time window, the network device or terminal device may determine that the stop condition (e) is not satisfied.

[0655] For the specific content of the 42nd time window, please refer to the above description of the 15th time window, which will not be repeated here.

[0656] Stop condition (f): The terminal device detects the first new beam.

[0657] Specifically, after the terminal device starts the first process, if the terminal device detects the first new beam, it can be determined that the stop condition (f) is met. If the terminal device does not detect the first new beam, it can be determined that the stop condition (f) is not met.

[0658] More specifically, if the terminal device detects the first new beam within the forty-third time window, it can be determined that the stop condition (f) is met. If the terminal device does not detect the first new beam within the forty-third time window, it can be determined that the stop condition (f) is not met. The starting moment of the forty-third time window can be any one of the following: the moment when the network device configures the first process, the transmission moment of the first RS, the moment when the terminal device detects the first event, the transmission moment of the first information, the transmission moment of the second information, the transmission moment of the trigger signaling, the transmission moment of the update signaling, and the transmission moment of the response to the update signaling. The duration of the forty-third time window can be configured by the network device. Alternatively, the duration of the forty-third time window can also be defined by the protocol.

[0659] Stop condition (g): The terminal device detects the first new cell.

[0660] Specifically, if the terminal device detects the first new cell during the first process, it may be determined that the stop condition (g) is satisfied. If the terminal device does not detect the first new cell during the first process, it may be determined that the stop condition (g) is not satisfied.

[0661] More specifically, if the terminal device detects the first new cell within the 44th time window, it can be determined that the stop condition (g) is met. If the terminal device does not detect the first new cell within the 44th time window, it can be determined that the stop condition (g) is not met. The starting time of the 44th time window can be any one of the following: the moment when the network device configures the first process, the transmission moment of the first first RS, the moment when the terminal device detects the first event, the transmission moment of the first information, the transmission moment of the second information, the transmission moment of the trigger signaling, the transmission moment of the update signaling, and the transmission moment of the response to the update signaling. The duration of the 44th time window can be configured by the network device. Alternatively, the duration of the 44th time window can also be defined by the protocol.

[0662] Stop condition (h): The terminal device receives second indication information, where the second indication information is used to indicate beam measurement, trigger beam reporting, indicate beam switching, or update the first RS.

[0663] Specifically, if the terminal device receives the second indication information, the terminal device can determine that the stop condition (h) is met. For example, during the parallel execution of the first process and the BFR process, the network device can send the second indication information to the terminal device. In this case, the terminal device may not need to continue to execute the BFR process, but instead perform beam measurement or report beam report or perform beam switching based on the second indication information, or detect a new beam based on the updated first RS. It should be noted that the specific timing of the network device sending the second indication information may depend on the autonomous decision of the network device, and this embodiment does not limit this.

[0664] In a specific implementation, the network device may send the second indication information to the terminal device during the first process. Specifically, the terminal device detects that the channel quality of the terminal device has deteriorated during the first process. The network device may send the second indication information to the terminal device upon learning that the channel quality of the terminal device has deteriorated.

[0665] In one example, if the network device receives the first information, the network device may send second indication information to the terminal device.

[0666] In another example, if the network device receives the first information, and the first information includes information about the first new beam, the network device may send second indication information to the terminal device.

[0667] Exemplarily, the network device sends a second indication message to update the first RS used for new beam detection. Further, after the stop condition of the BFR process is met, the BFR process is stopped, the first process can continue, and the terminal device can search for a new beam based on the updated first RS used for new beam detection.

[0668] Exemplarily, if the network device receives the first information within the 45th time window and / or the first information does not include information about the first new beam, the network device may send second indication information to the terminal device. The starting time of the 45th time window may be the time when the network device configures the first process or the time when the first first RS is transmitted. The duration of the 45th time window may be configured by the network device. Alternatively, the duration of the 45th time window may be defined by a protocol.

[0669] In a specific implementation, "the terminal device receives the second indication information" may be that the terminal device receives the second indication information within the forty-sixth time window. The starting time of the forty-sixth time window may be any one of the following: the moment when the network device configures the first process, the transmission moment of the first RS, the moment when the terminal device detects the first event, the transmission moment of the first information (such as the moment when the terminal device sends the first information), the transmission moment of the second information (such as the moment when the terminal device receives the second information). The duration of the forty-sixth time window may be configured by the network device. Alternatively, the duration of the forty-sixth time window may also be defined by the protocol.

[0670] Stop condition (i): The beam switching and / or cell switching in the first process is completed.

[0671] The completion of beam switching and / or cell switching in the first process may refer to switching to the first new beam and / or the first new cell.

[0672] Exemplarily, if the terminal device switches to the first new beam and / or switches to the first new cell in the first process, it can be determined that the stop condition (i) is met. If the terminal device does not switch to the first new beam and / or switches to the first new cell in the first process, it can be determined that the stop condition (i) is not met.

[0673] Exemplarily, if the network device switches to the first new beam during the first process, it can be determined that stop condition (i) is satisfied. If the network device does not switch to the first new beam, it can be determined that stop condition (i) is not satisfied. Switching the network device to the first new beam means that the network device begins to communicate with the terminal device using the first new beam.

[0674] Exemplarily, if the network device completes the cell handover in the first process, the network device may determine that the stop condition (i) is satisfied. Specifically, if the network device starts to provide services to the terminal device based on the first new cell in the first process, the network device may determine that the stop condition (i) is satisfied.

[0675] In a specific implementation, the completion of beam switching and / or cell switching in the first process may refer to the completion of beam switching and / or cell switching within the forty-seventh time window. The starting moment of the forty-seventh time window may be any one of the following: the moment when the network device configures the first process, the transmission moment of the first RS, the moment when the terminal device detects the first event, the transmission moment of the first information (such as the moment when the terminal device sends the first information), the transmission moment of the second information (such as the moment when the terminal device receives the second information), the transmission moment of the trigger signaling, the transmission moment of the response to the trigger signaling, the transmission moment of the beam report, the transmission moment of the update signaling, the transmission moment of the response to the update signaling, the transmission moment of the indication signaling, and the transmission moment of the response to the indication signaling. The duration of the forty-seventh time window may be configured by the network device. Alternatively, the duration of the forty-seventh time window may also be defined by the protocol.

[0676] Stop condition (j): The terminal device receives the fifth indication information, and the fifth indication information is used to indicate the stop of the BFR process.

[0677] Specifically, if the terminal device receives the fifth indication information, it can be determined that the stop condition (j) is met. If the terminal device does not receive the fifth indication information, the stop condition (j) is not met.

[0678] More specifically, if the terminal device receives the fifth indication information within the forty-ninth time window, it can be determined that the stop condition (j) is met. The starting moment of the forty-ninth time window can be at least one of the following: the moment when the network device configures the first process, the transmission moment of the first RS, the moment when the terminal device detects the first event, the transmission moment of the first information (such as the moment when the terminal device sends the first information), the transmission moment of the second information (such as the moment when the terminal device receives the second information), the transmission moment of the trigger signaling, the transmission moment of the response to the trigger signaling, the transmission moment of the beam report, the transmission moment of the update signaling, the transmission moment of the response to the update signaling, the transmission moment of the indication signaling, and the transmission moment of the response to the indication signaling. The duration of the forty-ninth time window can be configured by the network device. Alternatively, the duration of the forty-ninth time window can also be defined by the protocol.

[0679] In a specific implementation, whether to send the fifth indication information and the timing of sending the fifth indication information may depend on the autonomous decision of the network device.

[0680] In one example, if the network device receives the first information, the network device may send fifth indication information to the terminal device.

[0681] In another example, if the network device receives the first information and / or the first information includes information about the first new beam, the network device may send fifth indication information to the terminal device. Specifically, if the network device receives the first information and / or the first information includes information about the first new beam within the fiftieth time window, the network device may send fifth indication information to the terminal device. The starting moment of the fiftieth time window may be the moment when the network device configures the first process or the transmission moment of the first first RS. The duration of the fiftieth time window may be configured by the network device. Alternatively, the duration of the fiftieth time window may also be defined by a protocol.

[0682] As described above, in S52, the stop condition for the BFR process may include at least one of the stop conditions (a) to (j) described above. If the stop condition for the BFR process is met, the terminal device may stop the BFR process. Alternatively, if the network device determines that the stop condition for the BFR process is met, the network device may stop the BFR process. Conversely, if the stop condition for the BFR process is not met, the BFR process may continue to be executed. Furthermore, if the stop condition for the BFR process is met, the first process may continue to be executed.

[0683] Exemplarily, if the stop condition of the BFR process is met, the terminal device may reset the counter of the BFR process to zero and / or restart the timer of the BFR process. In other words, the terminal device stopping the first process may include: resetting the counter of the BFR process to zero and / or restarting the timer of the BFR process.

[0684] As described above, the counters of the BFR process may include: a counter for BFD and a counter for NBI. Exemplarily, if the stop condition of the BFR process is met, the terminal device may reset both the counter for BFD and the counter for NBI to zero.

[0685] For the specific contents of the counter and the timer of the BFR process, please refer to the relevant description above and will not be repeated here.

[0686] For example, if the stop condition of the BFR process is met, the terminal device may stop measuring BFDRS and NBIRS.

[0687] For example, if the stop condition of the BFR process is met, the network device may stop sending BFDRS and NBIRS.

[0688] For example, if the stop condition of the BFR process is met, the terminal device may stop receiving BFDRS and NBIRS.

[0689] For example, if the stop condition of the BFR process is met, the terminal device may stop sending the BFRQ. In other words, if the stop condition of the BFR process is met, the terminal device may cancel sending the BFRQ.

[0690] For example, if the stop conditions for the BFR process are met, the terminal device can suspend the currently initiated BFR process. In specific implementations, the conditions for resuming the suspended BFR process can refer to the above description of Example 3 and are not repeated here. In other words, when the start conditions for the BFR process in Example 3 are met, the suspended BFR process in this embodiment can resume execution.

[0691] For example, if the stop condition of the BFR process is met, the terminal device or network device may consider the BFR process to be completed. In other words, if the stop condition of the BFR process is met, the terminal device or network device may end the currently started BFR process.

[0692] From the above, in the scheme of Example 5, after the network device configures the terminal device to execute the BFR process and the first process, the network device or the terminal device can stop the BFR process when the first process detects that the channel quality has deteriorated or identifies a new beam. The terminal device can ensure the communication quality between the terminal device and the network device by executing the first process without continuing to execute the BFR process, which is beneficial to saving power consumption of the terminal device.

[0693] For more details about the fifth embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0694] Example 6

[0695] Reference Figure 6 , Figure 6 It is a flow chart of the sixth communication method in the embodiment of the present application. Figure 6 The method shown can be applied to a communication device. Specifically, Figure 6 The method shown can be applied to a terminal device or a network device. Figure 6 The illustrated method may include S61 and S62.

[0696] S61, start the RLM process;

[0697] S62: In response to the first starting condition being met, start the first process.

[0698] In a possible implementation of S61, after the network device configures parameters for the RLM process for the terminal device, the terminal device may start the RLM process. More specifically, in S61, the terminal device may start the RLM process based on the configuration of the network device.

[0699] In a specific implementation, the terminal device initiating the RLM process may include at least one of the following: the terminal device requests parameters for the RLM process; the terminal device receives configuration information including parameters for the RLM process (such as the second configuration information or configuration information above), the terminal device receives RLM-RS, the terminal device measures RLM-RS, the terminal device detects an RLF event, and starts a counter for the RLM process.

[0700] In another possible implementation of S61, the network device may initiate the RLM process. Specifically, the network device initiating the RLM process may include at least one of the following: the network device configuring parameters for RLM (that is, the network device sending parameters for RLM or sending configuration information including parameters for the RLM process), the network device sending an RLM-RS, and the network device confirming or knowing that the terminal device has initiated the RLM process.

[0701] It should be noted that the RLM process started in S61 may be independent of the first process. That is, the RLM process started in S61 may not depend on the first process.

[0702] In the solution of this embodiment, after starting the RLM process, the network device or the terminal device may determine whether a first starting condition is met, wherein the first starting condition is related to the RLM process.

[0703] Specifically, the starting condition of the first process may include at least one of the following starting conditions (1') to (7').

[0704] Start condition (1'): The terminal device does not detect an RLF event during the RLM process.

[0705] Specifically, if the terminal device does not detect an RLF event within the fifty-first time window, it may be determined that the start condition (1') is met. If the terminal device detects an RLF event within the fifty-first time window, it may be determined that the start condition (1') is not met.

[0706] The starting time of the fifty-first time window may be any one of the following: the time when the network device configures the RLM process, the time when the first RLM-RS is transmitted, and the duration of the fifty-first time window may be configured by the network device or defined by a protocol.

[0707] It should be noted that the "transmission moment of the first RLM-RS" in this article can be understood or described as at least one of the following: "the starting moment of the terminal device receiving the first RLM-RS", "the starting moment of the network device sending the first RLM-RS", "the starting moment of the terminal device measuring the RLM-RS", and "the starting moment of the terminal device detecting the RLF event".

[0708] It should also be noted that the "moment when the network device configures the RLM process" in this article can be understood or described as at least one of the following: the moment when the network device configures the parameters for the RLM process, the transmission moment of the configuration information including the parameters for the RLM process (such as the configuration information or the second configuration information in Example 1) (such as the moment when the network device sends the configuration information including the parameters for the RLM process, the moment when the terminal device receives the configuration information including the parameters for the RLM process).

[0709] Start condition (2'): the network device does not receive at least one of the following: radio link failure information, RRC re-establishment request information, random access channel.

[0710] Specifically, if the network device does not receive at least one of the following within the fifty-second time window: radio link failure information, RRC re-establishment request information, and random access channel, it can be determined that the start condition (2') is met. If the network device receives at least one of the following within the fifty-second time window: radio link failure information, RRC re-establishment request information, and random access channel, it can be determined that the start condition (2') is not met. For the specific contents of the radio link failure information, RRC re-establishment request information, and random access channel, please refer to the relevant description above and will not be repeated here.

[0711] The starting time of the fifty-second time window may be any of the following: the time when the network device configures the RLF process, the time when the first RLM-RS is transmitted, or the time when the terminal device detects a radio link failure. The duration of the fifty-second time window may be configured by the network device or defined by the protocol.

[0712] Start condition (3'): The terminal device does not receive an RRC re-establishment response during the RLM process.

[0713] Specifically, if the terminal device does not receive an RRC reestablishment response within the fifty-third time window, it can be determined that the start condition (3') is met. If the terminal device receives an RRC reestablishment response within the fifty-third time window, it can be determined that the start condition (3') is not met.

[0714] The RRC re-establishment response may refer to the cell switching indication or the RRC re-establishment information or the RRC establishment message or the RRC connection release indication mentioned above.

[0715] The starting time of the fifty-third time window may be any one of the following: the time when the network device configures the RLF process, the time when the first RLM-RS is transmitted, the time when the terminal device declares RLF, the time when at least one of radio link failure information, RRC re-establishment request information, and random access channel is transmitted (such as the time when the terminal device sends at least one of radio link failure information, RRC re-establishment request information, and random access channel). The duration of the fifty-third time window may be configured by the network device or may be defined by a protocol.

[0716] Start condition (4'): RRC reestablishment is not completed during the RLM process.

[0717] Specifically, if the RRC reestablishment is not completed within the fifty-fourth time window, the network device or the terminal device may determine that the start condition (4') is satisfied. In other words, if the RRC reestablishment is not successfully completed within the fifty-fourth time window, it may be determined that the start condition (4') is satisfied. If the RRC reestablishment is completed within the fifty-fourth time window, it may be determined that the start condition (4') is not satisfied.

[0718] Among them, the starting time of the fifty-fourth time window can be any one of the following: the time when the network device configures the RLF process, the transmission time of the first RLM-RS, the time when the terminal device declares RLF, the transmission time of at least one of the radio link failure information, RRC reconstruction request information, and random access channel (such as the time when the terminal device sends radio link failure information, RRC reconstruction request information, and at least one of the random access channel, such as the time when the network device receives radio link failure information, RRC reconstruction request information, and at least one of the random access channel), the transmission time of the RRC reconstruction response (such as the time when the terminal device receives the RRC reconstruction response, the time when the network device sends the RRC reconstruction response). The duration of the fifty-fourth time window can be configured by the network device or defined by the protocol.

[0719] Start condition (5'): The terminal device does not detect the second new beam and / or the second new cell during the RLM process.

[0720] Specifically, if the terminal device does not detect the second new beam and / or the second new cell within the fifty-fifth time window, the terminal device may determine that the start condition (5') is met. If the terminal device detects the second new beam and / or the second new cell within the fifty-fifth time window, it may determine that the start condition (5') is not met. The second new beam and the second new cell in this embodiment may be the new beam and the new cell determined during the RRC reestablishment process.

[0721] For the specific content of the fifty-fifth time window, please refer to the above description of the fifty-fourth time window, which will not be repeated here.

[0722] Start condition (6'): beam switching and / or cell switching during the RLM process is not completed.

[0723] The completion of beam switching and / or cell switching in the RLM process may refer to switching to the second new beam and / or the second new cell.

[0724] Exemplarily, if the terminal device does not switch to the second new beam and / or the second new cell within the fifty-sixth time window, the terminal device can determine that the start condition (6') is met. If the terminal device switches to the second new beam and / or the second new cell within the fifty-sixth time window, it can be determined that the start condition (6') is not met. In this embodiment, the second new cell can be a cell determined during the RRC re-establishment process, for example, it can be a cell indicated by a cell switching instruction, or a new cell selected by the terminal device by measuring the SSB of the alternative cell.

[0725] Exemplarily, if the network device does not switch to the second new beam within the fifty-sixth time window, the network device may determine that the start condition (6') is met. If the network device switches to the second new beam within the fifty-sixth time window, it may determine that the start condition (6') is not met.

[0726] As another example, if the cell handover is not completed within the fifty-sixth time window, the network device may determine that the start condition (6') is met. Specifically, if the network device does not provide services to the terminal device based on the second new cell within the fifty-sixth time window, the network device may determine that the start condition (6') is met. If the network device starts to provide services to the terminal device based on the second new cell within the fifty-sixth time window, the network device may determine that the start condition (6') is not met.

[0727] For the specific content of the fifty-sixth time window, please refer to the above description of the fifty-fourth time window, which will not be repeated here.

[0728] Start condition (7'): The terminal device receives first indication information, where the first indication information is used to indicate starting the first process.

[0729] Specifically, if the terminal device receives the first indication information after the RLM is started, it can be determined that the start condition (7') is met. If the terminal device does not receive the first indication information, the start condition (7') is not met.

[0730] More specifically, if the terminal device receives the first indication information within the fifty-seventh time window, it can be determined that the start condition (7') is met. For the specific content of the fifty-seventh time window, please refer to the above description of the fifty-fourth time window, which will not be repeated here.

[0731] In a specific implementation, whether to send the first indication information and the timing of sending the first indication information may depend on the autonomous decision of the network device.

[0732] In one example, if the network device receives at least one of radio link failure information, RRC reconstruction request information, and random access channel, the network device may send first indication information to the terminal device. Specifically, if the network device receives at least one of radio link failure information, RRC reconstruction request information, and random access channel within the fifty-eighth time window, the network device may send first indication information to the terminal device. The starting time of the fifty-eighth time window may be any one of the following: the moment when the network device configures the RLM process, the transmission moment of the first RLM-RS, and the moment when the terminal device declares RLF. The duration of the fifty-eighth time window may be configured by the network device, or may be defined by the protocol.

[0733] In another example, if the network device does not receive at least one of the radio link failure information, RRC reconstruction request information, and random access channel within the fifty-ninth time window, the network device may send a first indication message to the terminal device. If the network device does not receive at least one of the radio link failure information, RRC reconstruction request information, and random access channel within the fifty-ninth time window, the network device may deem that no RLF event has been detected, and the network device may instruct to start a first process to identify the deterioration of the channel quality of the terminal device through the first process, so as to promptly know and respond to the deterioration of the signal quality. The starting moment of the fifty-ninth time window may be any one of the following: the moment when the network device configures the RLM process, the moment when the first RLM-RS is transmitted, and the moment when the terminal device declares RLF. The duration of the fifty-ninth time window may be configured by the network device, or may be defined by the protocol.

[0734] If the network device receives at least one of the radio link failure information, RRC reconstruction request information, and random access channel within the fifty-ninth time window, the network device can send an RRC reconstruction response to the terminal device without sending the first indication information.

[0735] In another example, if during the RLM process, the network device receives HARQ-ACK information sent by the terminal device once or multiple times as NACK, it means that the quality of PDSCH transmitted using the current beam has deteriorated. At this time, the network device can send a first indication information to indicate the start of a first process to identify the deterioration of the beam quality in the current beam through the first process, so as to promptly know and respond to the deterioration of signal quality.

[0736] As described above, in the solution of this embodiment, the first starting condition may include at least one of the starting conditions (1') to (7') described above. If the terminal device determines that the first starting condition is satisfied, the terminal device may start the first process. If the network device determines that the first starting condition is satisfied, the network device may start the first process. Conversely, if the first starting condition is not satisfied, the first process is not started.

[0737] In one example, if the first start condition is met, the RLM process may be stopped. Exemplarily, after the first start condition is met, the terminal device may only execute the first process and no longer execute the RLM process. In this case, the start of the first process can be considered a stop condition for the RLM process. For more information on stopping the RLM process, please refer to the relevant description of Example 9 below and will not be repeated here.

[0738] In another example, if the start condition of the first process is met, the RLM process can continue to be executed. In other words, if the first start condition is met, the first process and the RLM process can be executed in parallel. For more details about the parallel execution of the first process and the RLM, please refer to the relevant description of the eighth and ninth embodiments below and will not be repeated here.

[0739] In a specific implementation, after the terminal device determines that the start condition of the first process is met, the counter of the first process may start counting.

[0740] In a first example, the counter of the first process may start counting from zero.

[0741] In a second example, the counter of the first process may start counting from the maximum count value of the RLM counter.
