[0003] In wireless communications, reference signals are transmitted between transmitters and receivers for purposes such as sending and receiving data, achieving system synchronization, and providing feedback on channel information. For example, the transmitter sends a reference signal to the receiver, which then receives the reference signal and performs corresponding operations based on the reference information, such as performing channel measurements and submitting measurement reports. Currently, the timing of measurement reports is primarily determined by network equipment, resulting in significant uplink resource overhead. Summary of the Invention

[0004] The present application provides a communication method and a communication device, which can realize the reporting of measurement reports related to events, reduce the overhead of uplink resources, and realize reasonable allocation of resources.

[0005] In the first aspect, a communication method is provided. This method can be applied to the terminal side, that is, the method can be executed by a terminal device or by a component of the terminal device (such as a chip or chip system or circuit or communication module), which is not limited in this application. The following mainly uses the terminal device as an example for description.

[0006] The method includes: receiving configuration information, the configuration information includes information about at least one event, and the at least one event is related to the measurement report reporting initiated by the terminal device; sending first information, the first information includes a measurement report related to an event occurring in the at least one event, and the load size corresponding to the first information is the load size corresponding to the measurement report related to the first event in the at least one event.

[0007] Based on the above technical solution, the terminal device can perform event-triggered reporting, thereby avoiding the terminal device from reporting invalid measurement reports to the network device. In addition, the terminal device can report measurement reports related to the occurred event using the first information with a fixed payload size, thereby avoiding resource waste caused by allocating corresponding reporting resources for each event when the terminal device supports or is configured with multiple events.

For example, the network devices may include a gNB-CU-CP, a gNB-CU-UP, and a gNB-DU.

[0096] In some deployments, multiple RAN nodes collaborate to assist terminals in achieving wireless access, with different RAN nodes implementing portions of the base station's functionality. For example, a RAN node can be a CU, DU, CU-CP, CU-UP, or radio unit (RU). The CU and DU can be separate or included in the same network element, such as the BBU. The RU can be included in a radio frequency device or radio unit, such as an RRU, AAU, or RRH.

[0097] In some deployments, the CU is a logical node that carries the radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP), and other control functions of access network equipment. The CU connects to network nodes, such as the core network, via interfaces, such as the E2 interface. Optionally, the CU performs some of the core network's functions. The CU (e.g., the PDCP layer and higher layers) connects to the DU (e.g., the radio link control (RLC) layer and lower layers) via interfaces, such as the F1 interface. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). The F1 application protocol (F1AP) is the application protocol for the F1 interface and, in some examples, defines the F1 signaling procedures. The F1 interface supports the control plane (F1 control plane, F1-C) and the user plane (F1 user plane, F1-U).

[0098] In some deployments, the CU can be split into CU-CP and CU-UP. The CU-CP is a logical node that carries the RRC layer and the control plane (control plane part of PDCP, PDCP-C) layer of PDCP, and is used to implement the control plane function of the CU. The CU-CP can interact with the network elements in the core network for implementing the control plane function. The network elements in the core network for implementing the control plane function may be access and mobility function network elements. The CU-UP is a logical node that carries the SDAP layer and the user plane (user plane part of PDCP, PDCP-U) layer of PDCP, and is used to implement the user plane function of the CU. The CU-UP can interact with the network elements in the core network for implementing the user plane function. The network elements in the core network for implementing the user plane function. The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are placed in the CU, while the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are placed in the DU. For another example, the functions of the CU or DU can be divided according to service type or other system requirements. For example, according to latency, functions that need to meet a smaller latency requirement are placed in the DU, while functions that do not need to meet this latency requirement are placed in the CU.

[0099] In some deployments, the DU is a logical node that carries the RLC layer, the medium access control / media access control (MAC) layer, the higher physical layer (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes parts of the physical (PHY) layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and other processing functions.

[0100] In some deployments, the RU is a logical node that carries the lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a TRP or RRH or other entity with similar functions. In some examples, Low-PHY includes part of the PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transform (IFFT), digital beamforming and filtering, and other processing functions. The RU communicates with one or more UEs over a wireless link.

[0101] The DU and RU may or may not be co-located. The DU and RU exchange control plane information and user plane information via the lower-layer split CUS-Plane (LLS-CUS) interface over the fronthaul link. The LLS-CUS may include interfaces and interfaces that provide the control plane and user plane, respectively. In some examples, the control plane refers to real-time control between the DU and RU. The DU and RU have an interface on the fronthaul link (such as the so-called LLS-M interface) to exchange management information, and the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0102] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0103] In one possible design, the processing unit for implementing baseband functions in the BBU is called a baseband high layer (BBH) unit, and the processing unit for implementing baseband functions in the RRU / AAU / RRH is called a baseband low layer (BBL) unit.

[0104] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, the radio access network may also be an open radio access network (O-RAN) architecture. In the O-RAN system, CU may also be called open CU (openCU, O-CU), DU may also be called open DU (open DU, O-DU), CU-CP may also be called open (open CU-CP, O-CU-CP), CU-UP may also be called open (open CU-UP, O-CU-UP), and RU may also be called open RU (openRU, O-RU). Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0105] In the embodiment of the present application, the device for realizing the function of the network device may be a network device, or a device capable of supporting the network device to realize the function, such as a chip system or a chip or a circuit or a communication module (i.e., a communication module that performs a communication function), and the device may be installed in the network device. In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices. In addition, program instructions for performing corresponding communication functions may also be configured in the device. In the embodiment of the present application, only the device for realizing the function of the network device is used as an example for explanation, and the solution of the embodiment of the present application is not limited.

[0106] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and satellites in the air. The embodiments of this application do not limit the scenarios in which network devices and terminal devices are located. In addition, terminal devices and network devices can be hardware devices, or they can be software functions running on dedicated hardware, software functions running on general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., a cloud platform), or entities including dedicated or general-purpose hardware devices and software functions. This application does not limit the specific forms of terminal devices and network devices.

[0107] First, a communication system applicable to the embodiments of the present application is briefly introduced as follows.

[0108] As shown in FIG1 , the communication system 100 may include one or more network devices, such as the network device 101 shown in FIG1 . The communication system 100 may also include one or more terminal devices, such as the terminal device 102, the terminal device 103, and the terminal device 104 shown in FIG1 . The communication system 100 may support sidelink communication technology, such as sidelink communication between the terminal device 102 and the terminal device 103, and sidelink communication between the terminal device 102 and the terminal device 104.

[0109] It should be understood that Figure 1 is only a schematic diagram, and the communication system may also include other network devices, such as core network device 105 and wireless relay devices and wireless backhaul devices not shown in Figure 1. The embodiments of the present application do not limit the number of network devices and terminal devices included in the mobile communication system.

[0110] The communication between the network device 101 and the terminal device 102 in the communication system shown in FIG1 can also be represented in another form.

[0111] As shown in Figure 2, terminal device 102 includes a processor 121, a memory 122, and a transceiver 123. Transceiver 123 includes a transmitter 1231, a receiver 1232, and an antenna 1233. Receiver 1232 can be configured to receive transmission control information via antenna 1233, and transmitter 1231 can be configured to send transmission feedback information to network device 101 via antenna 1233. Network device 101 includes a processor 111, a memory 112, and a transceiver 113. Transceiver 113 includes a transmitter 1131, a receiver 1132, and an antenna 1133. Transmitter 1131 can be configured to send transmission control information to terminal device 102 via antenna 1133, and receiver 1132 can be configured to receive transmission feedback information sent by terminal device 102 via antenna 1133.

[0112] The embodiments of the present application can also be applied to an open RAN (O-RAN) system architecture.

[0113] As shown in Figure 3, the O-RAN system may include core network (CN) equipment, access network equipment (RAN) and terminal equipment (UE). The access network equipment communicates with the core network equipment through a backhaul link and communicates with the terminal equipment through an air interface. For example, the BBU in the access network equipment communicates with the core network equipment through a backhaul link, and the RU in the access network equipment communicates with the terminal equipment through an air interface. The BBU communicates with at least one RU through a fronthaul link. The BBU and RU may or may not be co-located. The BBU includes at least one CU and at least one DU. The CU and DU may communicate through at least one midhaul link.

[0114] FIG3 is only a schematic diagram. The wireless communication system may also include other devices, which are not shown in FIG3 .

[0115] In order to facilitate a better understanding of the technical solution of this application, some related technologies involved in the technical solution of this application are introduced.

[0116] 1. Beam: A communication resource. Different beams can be considered different resources. Different beams can send the same or different information.

[0117] The embodiment of the beam in the NR protocol can be a spatial domain filter, or a spatial filter, or a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, or quasi-colocation, (Quasi-colocation, QCL) information, QCL assumption, QCL indication, etc. The beam can be indicated by a transmission configuration indicator (TCI) state (TCI-state or TCIstate) parameter, or by a spatial relation parameter. Therefore, in this application, the beam can be replaced by a spatial filter, a spatial filter, a spatial parameter, a spatial parameter, a spatial setting, a spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (DL TCI-state, UL TCI-state), a spatial relationship, etc. The above terms are also equivalent to each other. The beam can also be replaced by other terms representing the beam, which is not limited in this application.

[0118] The beam used to transmit a signal may be referred to as a transmission beam (Tx beam), or may be referred to as a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, or a spatial transmission parameter, or a spatial domain transmission setting. The downlink transmit beam may be indicated by a TCI-state.

[0119] The beam used to receive signals can be called a reception beam (Rx beam), and can also be called a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, or a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The uplink transmit beam can be indicated by a spatial relation, an uplink TCI-state, or a sounding reference signal (SRS) resource (indicating the transmit beam using the SRS). Therefore, the uplink beam, SRS resource, and uplink TCI state can be used interchangeably.

[0120] The transmit beam may refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the receive beam may refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0121] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beams. The beam forming technology can be beamforming technology or other technologies. The beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology.

[0122] Beams generally correspond to resources. For example, during beam measurement, network equipment uses different resources to measure different beams. The terminal device then provides feedback on the measured resource quality, allowing the network equipment to determine the quality of the corresponding beam. During data transmission, beam information is also indicated by its corresponding resource. For example, the network equipment uses the TCI field in the downlink control information (DCI) to indicate the physical downlink shared channel (PDSCH) beam information to the terminal device.

[0123] Optionally, multiple beams with the same or similar communication characteristics can be considered a single beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals. The one or more antenna ports forming a beam can also be considered an antenna port set.

[0124] 2. Reference signal (RS): This signal can also be called a pilot, reference sequence, or base signal. For consistency, the following description uses the term "reference signal." Reference signals can be used for channel measurement or estimation.

[0125] The channel measurement involved in this application also includes beam measurement, that is, obtaining beam quality information by measuring the reference signal. As an example, the parameters used to measure the beam quality include at least one of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal-to-noise ratio (SNR), signal to interference plus noise ratio (SINR) (or simply referred to as signal-to-interference ratio). In the embodiments of the present application, for the convenience of explanation, unless otherwise specified, the channel measurement involved can be regarded as beam measurement.

[0126] The reference signals involved in this application may, as examples, be any of the following: channel state information reference signal (CSI-RS), synchronization signal block (SSB), SRS, user equipment specific reference signal (US-RS), demodulation reference signal (DMRS), phase tracking reference signal (PT-RS), cell reference signal (CRS), etc. It should be understood that the reference signals listed above are only examples and should not constitute any limitation to this application. This application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0127] In addition, the reference signal can be understood as a reference signal associated with the handover candidate cell configuration. The handover candidate cell can also be called a candidate cell or a neighboring cell. The handover candidate cell can be the current serving cell or a non-serving cell. The physical cell identifier (PCI) of the handover candidate cell is different from the current primary cell (PCell). In addition, the reference signal can also be a reference signal associated with an additional PCI (additional PCI), that is, a reference signal of a neighboring cell.

[0128] The terminal device may be configured with one or more candidate cell configurations, and the configuration of each candidate cell may include a configuration of reference signal resources.

[0129] 3. Reference signal resources: can be used to configure the transmission properties of reference signals.

[0130] Typically, reference signals are configured as resources. Network equipment can configure each reference signal as a resource to a terminal device. A resource is a configuration information unit that typically includes parameters related to a reference signal, such as the reference signal's time-frequency resource location, number of ports, and time domain type (periodic, semi-static, or aperiodic). Transmitting devices can send reference signals based on the reference signal resources, and receiving devices can receive reference signals based on the reference signal resources.

[0131] In order to distinguish different reference signal resources, each reference signal resource may correspond to a reference signal resource identifier (or reference signal resource indication, or reference signal resource indicator), for example, a CSI-RS resource identifier (or CSI-RS resource indicator (CSI-RS resource indicator, CRI)), an SSB resource identifier (SSB resource indicator (SSB resource indicator, SSBRI)), or an SRS resource identifier (or SRS resource indicator (SRS resource indicator, SRI)).

[0132] 4. TCI-state (used to indicate downlink beam):

[0133] Network devices can generate different beams pointing in different transmission directions. In downlink data transmission, when a network device uses a specific beam to send data to a terminal device, it needs to inform the terminal device of the transmit beam information it uses. This allows the terminal device to use the receive beam corresponding to the transmit beam to receive the data sent by the network device. One possible method is for the network device to indicate to the terminal device the relevant information about the transmit beam it uses through the TCI (transmission configuration indication) field in the DCI.

[0134] For example, the TCI field size is 3 bits (bit), which can specifically represent 8 different field values ​​(codepoint). Each value of the TCI field corresponds to an index of a TCI-state, and the TCI-state index can uniquely identify a TCI-state. The TCI-state includes several parameters, through which the relevant information of the transmitted beam can be determined. The TCI-state is configured by the network device to each terminal device, and the structure of the TCI-state is shown below. Each TCI-state includes its own index TCI state identifier (tci-StateId), and two QCL information (QCL-Info). Each QCL-Info includes a cell field and a bandwidth part (band width part, BWP) identifier (identifier, ID), which respectively indicate which BWP of which cell the TCI-state is applied to, that is, different cells or different BWPs of the same cell can be configured with different QCL-Info. QCL-Info also includes a reference signal (referenceSignal) field, which is used to indicate which reference signal resource the beam indicated by the TCI-state forms a QCL relationship with. In data transmission and channel measurement, beams correspond to reference signal resources, and one beam corresponds to one reference signal resource. Therefore, when we say here that the beam indicated by TCI-state forms a QCL relationship with which reference signal resource, it actually means that the beam indicated by TCI-state forms a QCL relationship with which beam. A QCL relationship means that two reference signal resources (or two antenna ports, where antenna ports and reference signal resources also correspond one to one) have certain identical spatial parameters. Which specific spatial parameters are the same depends on the type of the QCL-Info, that is, another field of QCL-Info, QCL type (qcl-Type). qcl-Type can have four values ​​{type (type) A, typeB, typeC, typeD}. Taking typeD as an example, typeD indicates that the two reference signal resources have the same spatial reception parameter information, that is, the two beams have the same receiving beam. At most one of the two QCL-Info included in TCI-state can be TypeD.

[0135] The following example illustrates how a network device uses TCI-state to indicate the receive beam information of a data transmission beam to a terminal device, including the configuration, activation, and indication of TCI-state.

[0136] TCI-state configuration: The network device configures multiple TCI-states to the terminal device through RRC signaling. These TCI-states all include a QCL-Info of type D. The network device can also configure TCI-states that do not include QCL-Info of type D, without limitation.

[0137] TCI-state activation: After a network device is configured with multiple TCI-states, it must activate eight of them using a MAC control element (CE) (MACCE). These eight TCI-states correspond one-to-one to the eight values ​​of the TCI field in the DCI. The eight TCI-states corresponding to the eight values ​​of the DCI TCI field are determined through MAC CE signaling. The specific format of MACCE signaling is described in the protocol and is not specified.

[0138] TCI-state indication: The network device indicates a specific TCI-state through the TCI field in the DCI. For example, the value of the TCI field in the DCI sent by the network device to the terminal device is 000, indicating the TCI-state corresponding to 000 adopted by the data transmission beam. The reference signal contained in the QCL-Info of type D in the TCI-state is the reference signal with an index of #1 (such as CSI-RS), indicating that the beam used for data transmission is the same as the receiving beam corresponding to the CSI-RS with an index of #1. The receiving beam corresponding to the CSI-RS with an index of #1 can be determined through the beam measurement process and is known to the terminal device. Therefore, through the specific value of the TCI field, the terminal device can determine the receiving beam corresponding to the data transmission beam, and thus adopt the corresponding receiving beam to receive data.

[0139] 5. Spatial relation (used to indicate uplink beam)

[0140] In one possible implementation, the transmit beam for uplink transmission is indicated by a spatial relation, which has a function similar to TCI-state and is used to inform the terminal device which transmit beam to use for uplink transmission.

[0141] The spatial relation also needs to be configured through RRC signaling first. Its configuration structure may include the spatial relation ID, cell ID, target reference signal resource, path loss measurement reference signal, power control parameters, etc. Among them, the target reference signal resource (which can be one of SRS / SSB / CSI-RS) is used to indicate the corresponding uplink beam. If the uplink transmission adopts spatial relation #1, and the spatial relation #1 includes a target reference signal resource #2, it means that the transmission beam used for the uplink transmission is the transmission / reception beam of the target reference signal resource #2. For example, when the target reference signal resource #2 is an uplink SRS resource, it means that the transmission beam used for the uplink transmission is the transmission beam of the SRS (the transmission beam of the SRS is known). For another example, if the target reference signal resource #2 is a downlink resource such as SSB / CSI-RS, it means that the transmission beam used for the uplink transmission is the reception beam of the SSB / CSI-RS (the reception beam of the SSB / CSI-RS is known).

[0142] Network equipment can configure multiple spatial relations for terminal devices. One of them is then activated through MAC CE for the corresponding data transmission. Uplink transmission includes physical uplink control channel (PUCCH), SRS, physical uplink shared channel (PUSCH), etc. The above uplink transmissions all require the configuration of corresponding spatial relations. The spatial relation of PUCCH is indicated through MAC-CE signaling. The spatial relation of SRS is also indicated through MAC CE signaling. When PUSCH is transmitted, it will be associated with a specific SRS and use the spatial relation of the SRS for transmission.

[0143] 6. Unified TCI: It is a unified beam indication framework. The network device can indicate a beam to the terminal device, and the beam is used for multiple channels and / or reference signals at the same time. The common beam can be an uplink common beam, a downlink common beam, or an uplink and downlink common beam. The terminal device can use the common beam in subsequent transmissions. That is, the network device can indicate an uplink common beam to the terminal device for the transmission of multiple uplink channels and / or uplink reference signals. It can also indicate a downlink common beam to the terminal device for the transmission of multiple downlink channels and / or downlink reference signals. It can also indicate an uplink and downlink common beam to the terminal device for the transmission of multiple uplink channels and / or uplink reference signals, as well as multiple downlink channels and / or downlink reference signals. In other words, the uplink and downlink common beams can be used for both uplink and downlink transmissions.

[0144] As an example, the terminal device may be configured with two TCI-states, namely downlink (DL) or joint TCI (DL or joint TCI) and uplink (UL) TCI (UL TCI).

[0145] For example, the terminal device configures joint / DL TCI-state (eg, a maximum of 128) and UL TCI-state (eg, a maximum of 64) at the same time.

[0146] For another example, in the serving cell configuration of RRC signaling, the network device can configure the TCI mode currently used by the UE as joint mode or separate mode. In joint mode, a joint TCI-state is indicated for both uplink and downlink transmissions. In separate mode, the network device indicates that the DL TCI-state and UL TCI-state are used for uplink and downlink transmissions respectively.

[0147] When the terminal device receives the TCI-state activation signaling indicated by MACCE, the activation signaling includes the ID of the TCI-state. The terminal device determines which TCI is activated by MACCE based on the RRC configuration.

[0148] 7. Beam management: For example, it includes beam measurement, such as measuring based on reference signals to determine the beam with better quality.

[0149] 5G can utilize high-frequency communication, that is, ultra-high frequency band signals to transmit data. A major issue with high-frequency communication is that signal energy decreases dramatically with transmission distance, resulting in a short transmission distance. To overcome this problem, high-frequency communication uses simulated beam technology. By weighting the antenna array, the signal energy is concentrated within a smaller angular range, forming a signal similar to a light beam (called a simulated beam, or simply beam), thereby increasing the transmission distance. Both network equipment and terminal devices use beams for transmission. Specifically, specific beams are used for uplink and downlink data transmission between network equipment and terminal devices. Currently, beam management first performs coarse beam alignment based on the SSB, and then fine-tunes the beam based on the CSI-RS. The following describes the possible beam management process with reference to Figure 4.

[0150] See FIG. 4 , which is a schematic diagram of beam management applicable to an embodiment of the present application.

[0151] As an example, the overall process of beam management can be divided into the following three stages.

[0152] Phase 1: Coarse beam alignment between the network device and the terminal device, as shown in (a) in Figure 4.

[0153] Specifically, the network device performs network device beam scanning based on SSB, that is, the network device sends beams in different directions at different times to complete the broadcast beam coverage of the cell. At the same time, the terminal device scans the receive beam, that is, the terminal device also uses different beams for reception at different times. The terminal device determines the network device beam and the terminal device beam based on the received signal strength. For example, the network device beam is the beam with a received signal strength above a certain threshold (or called the optimal beam) among multiple beams, and the terminal device beam is the beam with a received signal strength above a certain threshold (or called the optimal beam) among multiple beams.

[0154] Phase 2: Network equipment beam fine-tuning, as shown in (b) in Figure 4.

[0155] Specifically, the network device determines the candidate beam based on the optimal network device beam obtained in stage 1, scans it through CSI-RS, and the terminal device receives it using the receiving beam selected in stage 1, thereby fine-tuning the network device beam to determine the network device beam with the highest signal strength (or called the optimal network device beam).

[0156] Phase 3: Fine-tuning of the terminal device beam, as shown in (c) in Figure 4.

[0157] Specifically, the network device transmits the CSI-RS using the optimal beam obtained in Phase 2, and the terminal device scans the beams to determine the terminal device beam with the highest signal strength (or the optimal terminal device beam), completing beam alignment. The process is similar to Phase 2.

[0158] Among them, stage 1, stage 2, and stage 3 are only examples, and the embodiments of the present application are not limited thereto. In implementation, a system does not necessarily need to implement all of the above processes. For example, it can only implement the processes of stage 1 and stage 2, and leave the determination of the receiving beam on the terminal device side to the terminal device.

[0159] 8. Measurement Result Reporting: Currently, network devices can configure three measurement result reporting (also known as beam reporting, beam measurement result reporting, or CSI reporting) processes based on the reporting time domain configuration behavior: periodic reporting, semi-persistent reporting, and aperiodic reporting. The following briefly describes these.

[0160] 1) Periodic Reporting: First, the network device configures periodic reference signal measurement. This means the network device periodically sends measurement reference signals to the terminal device, which then measures these reference signals and periodically reports the results. After the configuration signaling takes effect, the terminal device periodically reports measurement reports. To terminate the measurement reporting process, the terminal device can send RRC signaling to release the relevant configuration parameters for the measurement reporting process.

[0161] 2) Semi-continuous reporting: One is that the reference signal measurement is periodic, and the measurement result reporting is semi-continuous. First, the network device can configure a periodic reference signal, that is, the network device periodically sends a measurement reference signal to the terminal device, and the terminal device measures these reference signals. When the terminal device receives the activation signaling of the network device (such as MAC CE signaling, or DCI signaling), the terminal device will continuously and periodically report the measurement results. Of course, the network device can also send a deactivation signaling to the terminal device to deactivate the semi-continuous reporting process. The other is that both the reference signal measurement and the measurement result reporting are semi-continuous. When the terminal device receives the activation signaling of the network device (such as MAC CE signaling, or DCI signaling), the terminal device will continuously and periodically measure the reference signal and report the measurement results. When the terminal device receives the deactivation signaling sent by the network device, the terminal device stops the continuous reporting.

[0162] 3) Non-periodic reporting: This reporting is performed only after the terminal device receives a trigger signaling sent by the network device. After the reporting is completed, the terminal device will stop reporting, which is a one-time reporting.

[0163] The above-mentioned measurement result reporting is either periodic or semi-continuous or non-periodic reporting triggered by the indication signaling sent by the network device, that is, the timing of the reporting is determined by the network device. This method leads to a large overhead of uplink resources. Specifically, in periodic and semi-continuous measurement reporting, the terminal device needs to report the measurement results every other period, and these measurement results may be meaningless to the network device. For example, there is no difference between the current measurement result and the last reported measurement result (the optimal beam has not changed), and reporting such a measurement result is meaningless, resulting in a waste of uplink resources.

[0164] Based on this, beam reporting triggered by terminal devices or events is introduced. Specifically, terminal devices can report based on event triggers, and different events may trigger different reporting contents.

[0165] Before introducing the solution of this application, the following points are explained.

[0166] (1) In this application, “indication” may include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0167] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent together as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different.

[0168] (2) In this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information being XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information being YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between a network device and a terminal device, or can be carried out within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, a line or an interface.

[0169] (3) In the various embodiments of this application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0170] (4) In this application, the terms "first" and "second" are used for convenience of description only and are not intended to limit the scope of the embodiments of this application. They are not used to describe the order or precedence of features. It should be understood that the terms described in this manner may be interchangeable, where appropriate, to describe solutions other than the embodiments of this application.

[0171] (5) In this application, “predefined” may mean predefined by a standard protocol, or may mean pre-agreed or pre-negotiated between devices.

[0172] (6) In this application, words such as "exemplarily" and "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described in this application as an "example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "example" is intended to present concepts in a concrete way. In the embodiments of this application, "of", "corresponding, relevant" and "corresponding" are sometimes used interchangeably. It should be noted that when the distinction between them is not emphasized, the meanings they intend to express are consistent.

[0173] The method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings. The embodiment provided by the present application can be applied to the communication system shown in FIG1 above without limitation.

[0174] In the following embodiments, terminal devices and network devices are used as examples for illustrative description. The terminal device can be replaced by a component of the terminal device (such as a chip or a chip system or a circuit or a communication module), and the network device can be replaced by a component of the network device (such as a chip or a chip system or a circuit or a communication module).

[0175] Referring to Figure 5, Figure 5 is a schematic diagram of a communication method 500 provided in an embodiment of the present application. The method 500 shown in Figure 5 may include the following steps.

[0176] Optionally, method 500 includes S501 and S502.

[0177] S501: A terminal device sends first indication information. Correspondingly, a network device receives the first indication information.

[0178] The first indication information indicates event information supported by the terminal device. The first indication information may also be referred to as terminal capability information.

[0179] Among them, the event represents an event related to a report initiated by a terminal device (UE initiated report), or an event related to a measurement report report initiated by a terminal device, or an event related to a report (or measurement report) after the terminal device actively measures, or a specific condition related to a measurement report report initiated by a terminal device. For example, the terminal device can actively perform measurements (such as beam measurements, or channel measurements, etc.), and thereby obtain a measurement report related to the event. For another example, the terminal device can perform measurements based on a reference signal according to the configuration of reference signal resources, and thereby obtain a measurement report related to the event. For another example, the terminal device actively measures and reports a measurement report related to the event when specific conditions are met. Among them, the event can also be referred to as any of the following: a trigger event, a layer 1 (layer 1, L1) trigger event, a CSI measurement report trigger event, a beam measurement report trigger event, an L1 CSI report trigger event, an L1 beam measurement report trigger event, etc., and the embodiments of the present application are not limited to their naming.

[0180] In addition, as an example, an event-related report may be referred to as any of the following: an event-triggered or UE-initiated report, an event-triggered or UE-initiated beam report, an event-triggered or UE-initiated CSIreport, an event-triggered or UE-initiated beam measurement result report, an event-triggered or UE-initiated interference measurement report, an interference measurement report, a CSIreport, a beam measurement result report, etc.

[0181] Optionally, the first indication information indicates at least one of the following: whether the terminal device supports the capability of event triggering reporting, and the events supported by the terminal device.

[0182] Example 1: The first indication information indicates whether the terminal device supports the capability of event triggering reporting.

[0183] The event-triggered reporting may be event-triggered beam reporting, CSI reporting, beam measurement result reporting, interference measurement reporting, etc., which are not limited thereto. As an example, the event-triggered reporting may also be referred to as UE initiated report.

[0184] In one possible implementation, whether a terminal device supports event-triggered reporting is indicated by at least one bit. For example, a single bit is used to indicate whether the terminal device supports event-triggered reporting. If this bit is set to "0," it indicates that the terminal device supports event-triggered reporting; if this bit is set to "1," it indicates that the terminal device does not support event-triggered reporting. It should be understood that the above is merely an example and not limiting.

[0185] Another possible implementation method is to indicate whether the terminal device supports the event-triggered reporting capability by reporting whether the terminal device supports the event-triggered reporting capability. For example, if the terminal device does not report the capability of not supporting event-triggered reporting, it can be assumed that the terminal device supports the event-triggered reporting capability. Alternatively, for example, if the terminal device does not report the capability of supporting event-triggered reporting, it can be assumed that the terminal device does not support the event-triggered reporting capability.

[0186] The above is an example, and the embodiments of the present application are not limited thereto. For example, whether a terminal device supports the capability of event triggering and reporting can also be indicated by a specific field. If the first indication information includes the specific field, it indicates that the terminal device supports the capability of event triggering and reporting; if the first indication information does not include the specific field, it indicates that the terminal device does not support the capability of event triggering and reporting.

[0187] Example 2: The first indication information indicates an event supported by the terminal device.

[0188] For example, the first indication information includes the indexes of various events supported by the terminal device.

[0189] For another example, the first indication information includes indexes of various event tables supported by the terminal device, and an event table includes one or more events.

[0190] For another example, the first indicated information includes the number of events supported by the terminal device.

[0191] The above is an example description, and the embodiments of the present application are not limited thereto. The terminal device can indicate various information related to events supported by the terminal device to the network device.

[0192] S502: The terminal device receives configuration information. Correspondingly, the network device sends configuration information.

[0193] The configuration information includes information of X events, where X is an integer greater than 0. It should be understood that the X events may also be replaced by at least one event.

[0194] Regarding X events, there are three situations as follows.

[0195] In the first possible scenario, the X events are determined based on the first indication information. In other words, the X events are events supported by the terminal device, or in other words, the X events are events indicated by the terminal device via the first indication information. In this scenario, method 500 may not include S502, meaning that the network device may not configure information about the X events to the terminal device.

[0196] In the second possible scenario, the X events are configured by the network device, that is, the network device itself configures (or selects) the X events. In this case, the terminal device may be assumed to support all events or the X events. In this case, method 500 may not include S501, that is, the terminal device may not indicate the event information it supports to the network device.

[0197] In a third possible scenario, X events are determined based on the first indication information and events configured on the network device. For example, the network device is configured with at least one event, and the terminal device supports at least one event. The X events are determined based on a combination of the at least one event configured on the network device and the at least one event supported by the terminal device.

[0198] The above three possible scenarios are for illustration only, and the embodiments of the present application are not limited thereto. For simplicity, the following description will be made using X events.

[0199] Optionally, the configuration information indicates indexes of X events. The terminal device may learn about the X events based on the configuration information.

[0200] For example, the configuration information includes an index of each of the X events.

[0201] For another example, the configuration information includes one or more event tables (or indexes of one or more event tables), and one event table includes one or more events. In this way, based on the index of the event table included in the configuration information, the events contained in the event table can be known.

[0202] For another example, the configuration information includes the value of X.

[0203] Further optionally, the method 500 further includes: the network device sends activation signaling to the terminal device to activate part or all of the configured events (ie, X events).

[0204] Further optionally, the method 500 further includes: the network device sends a deactivation signaling to the terminal device, for deactivating some or all of the configured events (ie, X events).

[0205] Optionally, the X events include at least one of the following: the first beam quality is less than or equal to a first preset threshold, the second beam quality is greater than or equal to a second preset threshold, the second beam quality is greater than or equal to a third preset threshold of the first beam quality, and the difference between the second beam quality and the first beam quality is less than or equal to a fourth preset threshold.

[0206] The first beam represents a serving beam, i.e., the current serving beam; the second beam represents a beam different from the serving beam, such as a beam of a candidate cell / neighboring cell, etc. The first beam may include one or more beams, and the second beam may also include one or more beams.

[0207] For example, the current serving beam is a reference signal whose QCL type is typeD in the currently indicated TCI-state; or, the current serving beam is a reference signal whose QCL type is typeD in the UL TCI-state applied by the current uplink transmission (PUSCH / PUCCH / SRS / physical random access channel (PRACH)); or, the current serving beam is a reference signal whose QCL type is typeD in the downlink or joint TCI-state (DLorjointTCI-state) applied by the current downlink transmission (physical downlink control channel (PDCCH) / physical downlink shared channel (PDSCH) / CSI-RS). As an example, the reference signal is SSB, CSI-RS, SRS, etc.

[0208] The beam quality may be characterized by, for example, at least one of the following: reference signal receiving power (RSRP) and signal to interference plus noise ratio (SINR).

[0209] Each preset threshold, such as the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold, may be predefined, configured, indicated, or determined by the UE, without limitation. Each preset threshold may be the same or different. Two preset thresholds may be associated, meaning that an associated preset threshold can be derived from one preset threshold, or they may be unassociated. The units of each preset threshold may be decibel (dB), decibel milliwatt (dBm), etc.

[0210] The following describes the events listed above.

[0211] Example 1: The first beam quality is less than or equal to a first preset threshold.

[0212] For the sake of distinction, this event is referred to as event #A. In other words, event #A indicates that the current service beam quality is less than or equal to a certain threshold, such as the first preset threshold.

[0213] Example 2: The second beam quality is greater than or equal to a second preset threshold.

[0214] For distinction, this event is referred to as event #B. In other words, event #B indicates that there is at least one new beam (ie, the second beam) whose beam quality is greater than or equal to a threshold, such as the second preset threshold.

[0215] As an example, the new beam is a reference signal whose QCL type is typeD in the activated TCI-states (except the indicated TCI-state), or it can be one of the reference signals configured by the network device (such as the reference signal configured by the network device for measurement, and the reference signal configured by the network device for the terminal device to monitor the occurrence of events or event #B) (except the reference signal corresponding to the current service beam).

[0216] Example 3: The second beam quality is greater than or equal to a third preset threshold of the first beam quality.

[0217] To distinguish, this event is called event #C. In other words, event #C indicates that there is at least one new beam whose beam quality is greater than the beam quality of the current service beam, and the difference between the beam quality of the new beam and the beam quality of the current service beam is greater than or equal to a threshold, such as the third preset threshold.

[0218] Event #C can also be described as: the first beam quality is less than or equal to the second beam quality by a threshold. In this case, the threshold can be a value less than 0 dB. Alternatively, "the first beam quality is less than or equal to the second beam quality by a threshold" can be considered an event different from event #C, and this is not limited to this.

[0219] Example 4: The difference between the second beam quality and the first beam quality is less than or equal to a fourth preset threshold.

[0220] To distinguish, this event is called event #D. In other words, event #D indicates that the difference between the beam quality of at least one new beam and the beam quality of the current service beam is less than or equal to a threshold, or event #D indicates that the absolute value of the difference between the beam quality of at least one new beam and the beam quality of the current service beam is less than or equal to a threshold, such as the fourth preset threshold.

[0221] It is understood that the above is an example, and the embodiments of the present application are not limited thereto. The X events may also include other events. A few more examples are listed below.

[0222] Example 5: The beam quality of the first beam is less than or equal to a fifth preset threshold, and the beam quality of the second beam is greater than or equal to a sixth preset threshold, wherein the sixth preset threshold is greater than or equal to the fifth preset threshold.

[0223] To distinguish, this event is called event #E. In other words, event #E indicates that there is at least one new beam whose beam quality is greater than a certain threshold, and the beam quality of the current service beam is less than or equal to a threshold.

[0224] Example 6: The beam quality of the first beam is less than or equal to a seventh preset threshold of the beam quality of the preset beam.

[0225] For distinction, this event is referred to as event #F. For example, the current serving beam is a CSI-RS with a QCL type of type D in the currently indicated TCI-state, the preset beam is an SSB with a QCL type of type D for the CSI-RS, and the quality of the CSI-RS is less than or equal to the quality of the SSB by a threshold (i.e., the seventh preset threshold). In this case, the seventh preset threshold can be a value less than 0 dB.

[0226] The event #F can also be described as: the beam quality of the preset beam is greater than or equal to a threshold of the beam quality of the first beam. In this case, the threshold can be a value greater than 0 dB.

[0227] It can be understood that in the above examples, the situation regarding "equal" may be a situation where an event occurs, or it may be a situation where the event does not occur, that is, the above-defined event may not include "equal", or it may be used for other purposes, and there is no limitation on this.

[0228] S503: The terminal device sends first information, and the network device receives the first information accordingly.

[0229] If at least one of the X events occurs, the terminal device sends the first information to the network device. Taking event #A as an example, the occurrence of event #A indicates that the following situation has occurred: the first beam quality is less than the first preset threshold, or the first beam quality is equal to the first preset threshold. For example, if the terminal device determines through measurement that the first beam quality is less than or equal to the first preset threshold, it is determined that event #A has occurred. For another example, if the terminal device determines through measurement that the second beam quality is greater than or equal to the second preset threshold, it is determined that event #B has occurred. The occurrence of an event triggers a report, that is, triggers the reporting of the measurement report corresponding to the event.

[0230] The terminal device reports a measurement report related to one of the X events through the first information, that is, the first information includes a measurement report related to one of the X events, or the first information indicates a measurement report related to one of the X events. The load size corresponding to the first information is the load size corresponding to the measurement report related to the first event of the X events. The event occurring in the X events may be the first event or another event different from the first event, and this application does not limit this.

[0231] The first event may be a predefined event, or an event indicated by the network device to the terminal device, or an event indicated by the terminal device to the network device, or the first event is an event in which the load size of the relevant measurement report among the X events is greater than or equal to a threshold, for example, the first event is the event in which the load size corresponding to the relevant measurement report among the X events is the largest. For example, the X events are event #1, event #2, ..., event #X, and the load sizes corresponding to the measurement reports related to event #1, event #2, ..., event #X are P1, P2, ..., PX, respectively, where the load size Pn corresponding to the measurement report related to event #n is the largest among P1 to PX, then event #n is the first event.

[0232] Among them, the payload size corresponding to the event-related measurement report refers to the payload size required for reporting the measurement report related to the event, or the number of bits / bit space / bit width required for reporting the measurement report related to the event. Furthermore, the payload size required for reporting the measurement report related to the event refers to the payload size (or number of bits / bit space / bit width) required for the reporting parameters included in the measurement report related to the event. For example, the measurement report related to event #m includes reporting parameter #a, reporting parameter #b, ..., reporting parameter #k, and the number of bits required to report each reporting parameter in sequence is Pa, Pb, ..., Pk respectively. Then, the payload size required for reporting the measurement report related to event #m is (Pa+Pb+...+Pk). For example, the measurement report related to event #m includes k reporting parameters #a, 1 reporting parameter #b, ..., m reporting parameters #k. The number of bits required to report each reporting parameter in sequence is Pa, Pb, ..., Pk respectively. Then, the payload size required for reporting the measurement report related to event #m is (k*Pa+Pb+...+m*Pk). Among them, reporting parameter #a can be one of reporting parameters #1 to reporting parameters #11 described below, reporting parameter #b can be one of reporting parameters #1 to reporting parameters #11 described below, ..., reporting parameter #k can be one of reporting parameters #1 to reporting parameters #11 described below. Alternatively, one or more of reporting parameters #a to reporting parameters #k may not be limited to the reporting parameters described below. It can be understood that when the terminal device and the network device determine the measurement report related to the event, the load size required for reporting the measurement report related to the event can be determined.

[0233] The measurement reports related to different events among the X events may be predefined by a protocol, or may be configured by a network device, which is not limited in this application.

[0234] Optionally, measurement reports related to at least two events among the X events are different.

[0235] Optionally, there are at least two events among the X events, and the measurement reports corresponding to the event have different payload sizes.

[0236] The measurement report related to any one of the X events may include one or more of the following reporting parameters (or referred to as reporting quantities).

[0237] Reporting parameter #1, the current service beam index, can also be understood as the reference signal index of the QCL type in the currently indicated TCI-state is typeD; or, the reference signal index of the QCL type in the UL TCI-state applied for the current uplink transmission (PUSCH / PUCCH / SRS / PRACH) is typeD; or, the reference signal index of the QCL type in the downlink or joint TCI-state (DLorjointTCI-state) applied for the current downlink transmission (PDCCH / PDSCH / CSI-RS) is typeD.

[0238] Report parameter #2, the quality of the current serving beam, for example, the RSRP or SINR of the current serving beam.

[0239] Among them, the current service beam may include one beam or multiple beams, which is not limited in this application. The number of current service beams can be determined according to the number of UL / DL / jointTCI states indicated by the network device, such as the UL / DL / jointTCI state indicated by the DCI signaling. Alternatively, the number of beams included in the current service beam may be predefined by the protocol or preconfigured by the network device. Alternatively, the maximum number of beams included in the current service beam may be predefined by the protocol or configured by the network device.

[0240] Reporting parameter #3, the index of the second beam, can also be understood as the reference signal index of the activated TCI-states (except the indicated TCI-state) whose QCL type is typeD, or it can be the index of one or more reference signals (except the reference signal corresponding to the current service beam) in the reference signal configured by the network device (such as the reference signal configured by the network device for measurement, and the reference signal configured by the network device for the terminal device to monitor the occurrence of events).

[0241] Report parameter #4, the quality of the second beam, for example, the RSRP or SINR of the second beam.

[0242] The second beam may include one beam or multiple beams, which is not limited in this application. The number of beams included in the second beam may be predefined by the protocol or preconfigured by the network device. Alternatively, the maximum number of beams included in the second beam may be predefined by the protocol or configured by the network device.

[0243] Reporting parameter #5, cell information, can also be understood as which cell the reported measurement report corresponds to, or which cell's reference signal resources the reported measurement result is measured. For example, the cell information can be a handover candidate cell ID, a non-serving cell ID (additional PCI), a component carrier (CC) index, or a PCI. The ID mentioned in the embodiments of the present application can be an abbreviation of any one of identifier, indication, indicator, index, identity, and identification, and identifier, indication, indicator, index, identity, and identification can be interchangeable.

[0244] Report parameter #6: The reason why the current serving beam quality is below a threshold (e.g., a first preset threshold). Examples include network device beam misalignment, terminal device receive beam misalignment, or transmit / receive beam misalignment. The term "misaligned" can also be replaced with "expired" or "invalid." Alternatively, it indicates whether to trigger CSI-RS set measurements with "repetition" set to "on" to poll the UE's receive beam.

[0245] Reporting parameter #7, reference signal resource set index, for example, CSI-RS resource set (CSI-RS-ResourceSet) index, CSI interference measurement (interferencemeasurement, IM) resource set (CSI-IM-ResourceSet) index, CSI-SSB resource set (CSI-SSB-ResourceSet) index, or a reference signal resource set index configured by the network device for the terminal device to monitor the occurrence of events, used to indicate to which reference signal resource set the reported current serving beam and / or second beam belongs.

[0246] Reporting parameter #8, reporting configuration index, for example, CSI report configuration identifier (CSI-ReportConfigId), or event-triggered reporting configuration index.

[0247] Report parameter #9, event information, such as the index of the event that occurred, or one or more bits used to indicate whether the event occurred. For example, event information includes M bits, Used to indicate the index of an event that occurred. For another example, event information includes X bits, each of which corresponds to X events. The xth bit of the X bits is used to indicate whether the event corresponding to the xth bit has occurred, where x = 1, 2, ..., X. For example, if the value of the xth bit is "0", then the xth bit is used to indicate that the event corresponding to the xth bit has occurred. Alternatively, if the value of the xth bit is "1", then the xth bit is used to indicate that the event corresponding to the xth bit has occurred.

[0248] Report parameter #10, capability index, is used to determine the maximum number of SRS ports.

[0249] Reporting parameter #11, channel state information, for example, may include one or more of precoding matrix indicator (PMI), rank indicator (RI), channel quality indicator (CQI), and layer indicator (LI).

[0250] Optionally, if the measurement report related to one of the X events includes multiple reporting parameters, the terminal device reports the multiple reporting parameters in a predefined or preconfigured reporting order. In other words, the bit space of the first information is allocated to the multiple reporting parameters included in the measurement report related to one of the X events in a predefined or preconfigured order. For example, the measurement report related to one of the X events includes the above-mentioned reporting parameter #1 and reporting parameter #2. According to the predefined or preconfigured reporting order, the terminal device first reports reporting parameter #1 and then reports reporting parameter #2, that is, reporting parameter #1 occupies the bit space in front of the first information, and reporting parameter #2 occupies the bit space after the first information.

[0251] Optionally, if one of the X events is the second event, and the payload size corresponding to the measurement report related to the second event is smaller than the payload size corresponding to the first information, then the portion of the first information other than the measurement report related to the second event is a predefined value. For example, the remaining bits in the first information other than the bits used to carry the measurement report related to the second event are filled with 0. For example, the payload size of the first information is S bits, and the payload size corresponding to the measurement report related to the second event is L bits. If L<S, the first L bits of the first information are used to carry the measurement report related to the second event, and the remaining bits are filled with 0. S and L are positive integers. For another example, the payload size of the first information is S bits, and the measurement report related to the second event includes reporting parameter #a and reporting parameter #b. The number of bits required for reporting parameter #a and reporting parameter #b are Pa and Pb respectively. If (Pa+Pb)<S, the first (Pa+Pb) bits of the first information are used to carry the measurement report related to the second event, and the remaining bits are filled with 0. Among them, the reporting parameter #a can be one or more of the reporting parameters #1 to reporting parameters #11 described above, and the reporting parameter #b can be one or more of the reporting parameters #1 to reporting parameters #11 described above.

[0252] The second event is different from the first event. It is understood that if the first event is the event with the largest payload size corresponding to the related measurement report among the X events, the second event can be any event among the X events except the first event.

[0253] Optionally, if one of the X events is the third event, and the load size corresponding to the measurement report related to the third event is larger than the load size corresponding to the first information, the first information includes part of the measurement report in the measurement report related to the third event. For example, the terminal device may discard (drop) part of the measurement report in the measurement report related to the third event according to a predefined or preconfigured reporting order. For example, the load size of the first information is S bits, and the load size corresponding to the measurement report related to the third event is L' bits. If L'>S, the terminal device drops the last (L'-S) bits in the measurement report related to the third event, and reports the first S bits in the measurement report related to the third event through the first information. L' is a positive integer. For another example, the payload size of the first information is S bits, and the measurement report related to the third event includes reporting parameter #c, reporting parameter #d and reporting parameter #e. The number of bits required for reporting parameter #c, reporting parameter #d and reporting parameter #e are Pc, Pd and Pe respectively. If (Pc+Pd+Pe)>S, the terminal device reports some parameters of reporting parameter #c, reporting parameter #d and reporting parameter #e through the first information in a predefined or preconfigured reporting order. For example, if the reporting order of reporting parameter #c and reporting parameter #d is in the front, and (Pc+Pd)≤S, (Pc+Pd+Pe)>S, then the terminal device drops reporting parameter #e, and reports reporting parameter #c and reporting parameter #d through the first information, or the terminal device drops the last (S-Pc-Pd) bits of reporting parameter #e, and reports reporting parameter #c, reporting parameter #d and the first (Pc+Pd+Pe-S) bits of reporting parameter #e through the first information. Among them, reporting parameter #c can be one or more of reporting parameters #1 to reporting parameters #11 described above, reporting parameter #d can be one or more of reporting parameters #1 to reporting parameters #11 described above, and reporting parameter #e can be one or more of reporting parameters #1 to reporting parameters #11 described above.

[0254] Among them, the third event is different from the first event.

[0255] Optionally, if one of the X events is a fourth event, and the payload size corresponding to the measurement report related to the fourth event is equal to the payload size corresponding to the first information, then the first information includes all measurement reports in the measurement report related to the fourth event, and there is no need to fill in the predefined value. In other words, the terminal device can report the measurement report related to the fourth event in a predefined or preconfigured reporting order.

[0256] The fourth event is the same as or different from the first event.

[0257] Optionally, if one of the X events is a fifth event, the measurement report related to the fifth event includes one or more reporting parameters, and the number of reports corresponding to reporting parameter #f in the one or more reporting parameters is less than the maximum number of reports corresponding to reporting parameter #f specified by the network device or protocol, then the portion of the first information corresponding to reporting parameter #f, excluding reporting parameter #f included in the measurement report related to the fifth event, is a predefined value. Reporting parameter #f may be one of reporting parameters #1 to reporting parameter #11 described above. For example, the reporting parameter #f is the reporting parameter #3 described above, that is, the index of the second beam. The network device or protocol stipulates that the maximum number of beams included in the second beam is 4. In this case, the number of bits corresponding to the reporting parameter #f in the first information is Pf. Pf bits can be used to carry the indexes of 4 beams, and the reporting parameter #f included in the measurement report related to the fifth event includes the indexes of 2 beams. The number of bits required for the indexes of the 2 beams is Pf / 2. Therefore, Pf / 2 bits of the Pf bits corresponding to the reporting parameter #f in the first information carry the reporting parameter #f included in the measurement report related to the fifth event, and the other Pf / 2 bits are filled with 0.

[0258] Optionally, if at least one of the X events occurs, and the terminal device does not need to report a measurement report for the at least one event, the terminal device does not send the first information.

[0259] Optionally, if at least one of the X events occurs and the terminal device does not send the first information, the terminal device may send indication information #1 to the terminal device, where the indication information #1 indicates at least one of the following: whether an event among the X events occurs, and information about the event that occurred among the X events.

[0260] Optionally, the events occurring among the X events include multiple events, and the terminal device reports a measurement report related to one of the multiple events occurring through the first information. For example, the terminal device reports a measurement report related to an event ranked first among the multiple events occurring through the first information in a predefined or preconfigured first order. For example. The events occurring among the X events include event #m and event #r, and event #m is ranked first, then the terminal device reports the measurement report related to event #m through the first information. Optionally, the terminal device can also report the measurement report related to event #r through the second information. For more descriptions of the second information, please refer to the first information. Among them, the predefined or preconfigured first order can be: in order from large to small according to the index of the event, or in order from small to large according to the index of the event, or in order from high to low according to the priority of the event.

[0261] Optionally, the terminal device may report measurement reports related to multiple events occurring in X events through the first information. If the sum of the load sizes corresponding to the measurement reports related to the multiple events occurring in the X events is less than the load size of the first information, the first information sent by the terminal device may include measurement reports related to the multiple events occurring, and the part of the first information other than the measurement reports related to the multiple events occurring is a predefined value. For example, the part of the first information other than the measurement reports related to the multiple events occurring is filled with all 0s. For example, the multiple events occurring in the X events include the sixth event and the seventh event, and the sum of the load size corresponding to the measurement report related to the sixth event and the load size corresponding to the measurement report related to the seventh event is less than the load size of the first information, then the first information sent by the terminal device may include the measurement report related to the sixth event and the measurement report related to the seventh event. Assuming that the load size of the first information is S, the load size required for the measurement report related to the sixth event is S1, and the load size required for the measurement report related to the seventh event is S2, (S1+S2)<S, then the first (S1+S2) bits of the first information are used to carry the measurement reports related to the sixth event and the seventh event, and the last (S-S1-S2) bits of the first information are filled with all 0s.

[0262] Optionally, if the sum of the load sizes corresponding to the measurement reports related to multiple events occurring in the X events is greater than the load size of the first information, the terminal device can report the measurement reports related to some of the multiple events occurring in accordance with a predefined or preconfigured first order. In other words, the terminal device can discard (drop) the measurement reports related to some of the multiple events occurring in accordance with a predefined or preconfigured first order. For example, the multiple events occurring in the X events include the eighth event and the ninth event, and the sum of the load size corresponding to the measurement report related to the eighth event and the load size corresponding to the measurement report related to the ninth event is greater than the load size of the first information, and the eighth event is sorted first, then the terminal device can drop the measurement report related to the ninth event, and report the measurement report related to the eighth event through the first information. Alternatively, if the load size corresponding to the measurement report related to the eighth event is smaller than the load size corresponding to the first information, the terminal device can report all measurement reports related to the eighth event and part of the measurement report related to the ninth event through the first information. For example, the terminal device can report part of the reporting parameters in the measurement report related to the ninth event in a predefined or preconfigured reporting order, and drop the remaining reporting parameters.

[0263] Optionally, if the sum of the load sizes corresponding to the measurement reports related to multiple events occurring in X events is equal to the load size of the first information, the first information includes all measurement reports in the measurement reports related to the multiple events that occurred, and the first information does not need to be filled with a predefined value. For example, the terminal device can report the measurement reports related to the multiple events that occurred in a predefined or preconfigured first order.

[0264] Optionally, X events are associated with X different measurement report configurations, or X events are associated with the same measurement report configuration. Exemplarily, the measurement report configuration includes one or more of the following: beam measurement configuration, conditions for triggering measurement reports (such as one or more of the above X events), measurement report format, and measurement report period. Exemplarily, the beam measurement configuration may include information such as the measured beam identifier, frequency bandwidth, and reference signal type.

[0265] In a possible implementation manner, measurement reports related to X events are reported through the same uplink resource, that is, the first information including measurement reports related to different events is sent through the same uplink resource.

[0266] Optionally, the method 500 further includes: the network device configuring, for the terminal device, a same uplink resource associated with X event-related measurement reports.

[0267] In another possible implementation, measurement reports related to X events are reported through different uplink resources, that is, the first information including measurement reports related to different events is sent through different uplink resources.

[0268] Optionally, the method further includes: the network device configuring, for the terminal device, X uplink resources associated with measurement reports related to X events, one uplink resource of the X uplink resources being associated with a measurement report related to one of the X events. Optionally, the X uplink resources may be different uplink resources. Then, when a tenth event of the X events occurs, the payload size of the first information including the measurement report related to the tenth event is the payload size corresponding to the measurement report related to the tenth event.

[0269] In an embodiment of the present application, a terminal device can perform event-triggered reporting, thereby preventing the terminal device from reporting invalid measurement reports to a network device. In addition, the terminal device can report measurement reports related to an event that has occurred using first information with a fixed payload size, thereby avoiding resource waste caused by allocating corresponding reporting resources for each event when the terminal device supports or is configured with multiple events.

[0270] Referring to Figure 6, Figure 6 is a schematic diagram of another communication method 600 provided in an embodiment of the present application. The method 600 shown in Figure 6 may include the following steps.

[0271] Optionally, method 600 includes S601 and S602.

[0272] S601: A terminal device sends first indication information, and a network device receives the first indication information accordingly.

[0273] For more description of S601, please refer to S501 in the above method 500. For the sake of brevity, it will not be repeated here.

[0274] S602: The terminal device receives configuration information, and the network device sends configuration information accordingly.

[0275] For more description of S602, please refer to S502 in the above method 500, which will not be repeated here for the sake of brevity.

[0276] S603: The terminal device sends the first information, and the network device receives the first information accordingly.

[0277] If at least one of the X events occurs, the terminal device sends the first information to the network device. Taking event #A as an example, the occurrence of event #A indicates that the following situation has occurred: the first beam quality is less than the first preset threshold, or the first beam quality is equal to the first preset threshold. For example, if the terminal device determines through measurement that the first beam quality is less than or equal to the first preset threshold, it is determined that event #A has occurred. For another example, if the terminal device determines through measurement that the second beam quality is greater than or equal to the second preset threshold, it is determined that event #B has occurred. The occurrence of an event triggers a report, that is, triggers the reporting of the measurement report corresponding to the event.

[0278] The terminal device reports a measurement report related to at least one event occurring among X events through the first information, that is, the first information includes a measurement report related to at least one event occurring among X events, or the first information indicates a measurement report related to at least one event occurring among X events.

[0279] The first information is in a predefined format. Two possible formats of the first information are described below.

[0280] Format 1: The first information includes at least one public field and at least one non-public field.

[0281] Among them, at least one public field corresponds to at least one public reporting parameter. For example, at least one public field corresponds to at least one public reporting parameter one-to-one. Taking public field #1 in at least one public field as an example, public field #1 is used to carry the public reporting parameter corresponding to public field #1. In other words, the payload size of public field #1 is the payload size corresponding to the public reporting parameter corresponding to public field #1. It should be noted that the public field can also be named with other names, which is not limited in this application. The public reporting parameter can also be named with other names, which is not limited in this application.

[0282] It should be understood that if the measurement report related to the event occurring in the X events includes the common reporting parameter corresponding to the common field #1, then the common field #1 included in the first information carries the common reporting parameter corresponding to the common field #1. If the measurement report related to the event occurring in the X events does not include the common reporting parameter corresponding to the common field #1, or in other words, none of the events in which the measurement report includes the common reporting parameter corresponding to the common field #1 has occurred, then the common field #1 included in the first information is a predefined value, for example, each bit of the common field #1 included in the first information is filled with 0.

[0283] At least one non-public field corresponds to at least one non-public reporting parameter. For example, at least one non-public field corresponds to at least one non-public reporting parameter one-to-one. Taking non-public field #1 in at least one non-public field as an example, non-public field #1 is used to carry the non-public reporting parameter corresponding to non-public field #1. In other words, the load size of non-public field #1 is the load size corresponding to the non-public reporting parameter corresponding to non-public field #1. It should be noted that the non-public field can also be named with other names, which is not limited in this application. The non-public reporting parameter can also be named with other names, which is not limited in this application.

[0284] It should be understood that if the measurement report related to the event occurring in the X events includes the non-public reporting parameter corresponding to the non-public field #1, then the non-public field #1 included in the first information carries the non-public reporting parameter corresponding to the non-public field #1. If the measurement report related to the event occurring in the X events does not include the non-public reporting parameter corresponding to the non-public field #1, or in other words, if the event in which the measurement report includes the non-public reporting parameter corresponding to the non-public field #1 does not occur, then the non-public field #1 included in the first information is a predefined value, for example, each bit of the non-public field #1 included in the first information is filled with 0.

[0285] In summary, the payload size of the first information is the payload size required to report at least one public reporting parameter and at least one non-public reporting parameter.

[0286] Common reporting parameters are reporting parameters with the same value included in at least two of the X events. For example, common reporting parameters include one or more of the following: reporting parameter #1, reporting parameter #2, reporting parameter #3, reporting parameter #4, reporting parameter #5, reporting parameter #6, reporting parameter #7, reporting parameter #8, reporting parameter #10, and reporting parameter #11. For more information about the above reporting parameters, please refer to S503 of method 500 above.

[0287] Non-public reporting parameters are reporting parameters with different values ​​included in measurement reports related to different events among the X events. For example, non-public reporting parameters are one or more of the following: reporting parameter #3, reporting parameter #4, reporting parameter #7, reporting parameter #8, and reporting parameter #9. For more description of the above reporting parameters, please refer to S503 in method 500 above.

[0288] The following uses an example to illustrate the method of determining the format of the first information.

[0289] As shown in Table 1, X events include four events, namely, event #1 to event #4. The measurement report related to event #1 includes reporting parameter #g, the measurement report related to event #2 includes reporting parameter #g and reporting parameter #h, the measurement report related to event #3 includes reporting parameter #g and reporting parameter #i, and the measurement report related to event #4 includes reporting parameter #i and reporting parameter #j. Reporting parameter #g is one of reporting parameters #1 to reporting parameters #11 described in S503 above, reporting parameter #h is one of reporting parameters #1 to reporting parameters #11 described in S503 above, reporting parameter #i is one of reporting parameters #1 to reporting parameters #11 described in S503 above, reporting parameter #j is one of reporting parameters #1 to reporting parameters #11 described in S503 above, and reporting parameter #1 is one of reporting parameters #1 to reporting parameters #11 described in S503 above.

[0290] Table 1

[0291] The measurement reports related to event #1, event #2, and event #3 all include reporting parameter #g. If reporting parameter #g is a public reporting parameter, the first information includes a public field corresponding to reporting parameter #g (denoted as public field #1). The measurement reports related to event #2 include reporting parameter #h, and the measurement reports related to the remaining events do not include reporting parameter #h. If reporting parameter #h is a non-public reporting parameter, the first information includes a non-public field corresponding to reporting parameter #h (denoted as non-public field #1). The measurement reports related to event #3 and event #4 both include reporting parameter #i. If the value of reporting parameter #i included in the measurement report related to event #3 is the same as the value of reporting parameter #i included in the measurement report related to event #4, then reporting parameter #i is a public reporting parameter, and the first information includes a public field corresponding to reporting parameter #i (denoted as public field #2); if the value of reporting parameter #i included in the measurement report related to event #3 is different from the value of reporting parameter #i included in the measurement report related to event #4, then reporting parameter #3 is a non-public reporting parameter, and the first information includes a non-public field corresponding to reporting parameter #i included in the measurement report related to event #3 (denoted as non-public field #2), and a non-public field corresponding to reporting parameter #i included in the measurement report related to event #4 (denoted as non-public field #3). The measurement related to event #4 includes reporting parameter #j, and the measurement reports related to other events do not include reporting parameter #j. Then the reporting parameter #j is a non-public reporting parameter, and the first information includes a non-public field corresponding to reporting parameter #j (recorded as non-public field #4).

[0292] In summary, based on the four events shown in Table 1 and the measurement reports related to the events, a possible format of the first information is: the first information includes a common field #1, a non-common field #1, a common field #2, and a non-common field #4. Among them, the common field #1 is used to carry the reporting parameter #g included in the measurement reports related to events #1 to #3, the non-common field #1 is used to carry the reporting parameter #h included in the measurement report related to event #2, the common field #2 is used to carry the reporting parameter #i included in the measurement reports related to events #3 and #4, and the non-common field #4 is used to carry the reporting parameter #j included in the measurement report related to event #4. The payload size of the first information is the sum of the payload size corresponding to the reporting parameter #g, the payload size corresponding to the reporting parameter #h, the payload size corresponding to the reporting parameter #i, and the payload size corresponding to the reporting parameter #j.

[0293] If event #1 and event #2 among events #1 to #4 occur, the first information sent by the terminal device can be as shown in Table 2, that is, the reporting parameter #g is carried on the public field #1, the reporting parameter #h is carried on the non-public field #1, and the public field #2 and the non-public field #4 are predefined values, for example, filled with all 0s.

[0294] Table 2

[0295] Based on the four events shown in Table 1 and the measurement reports related to the events, another possible format of the first information is as follows: the first information includes common field #1, non-common field #1, non-common field #2, non-common field #3, and non-common field #4. Common field #1 is used to carry reporting parameter #g included in the measurement reports related to events #1 to #3, non-common field #1 is used to carry reporting parameter #h included in the measurement report related to event #2, non-common field #2 is used to carry reporting parameter #i included in the measurement report related to event #3, non-common field #3 is used to carry reporting parameter #i included in the measurement report related to event #4, and non-common field #4 is used to carry reporting parameter #j included in the measurement report related to event #4. The payload size of the first information is the sum of the payload size corresponding to reporting parameter #g, the payload size corresponding to reporting parameter #h, the payload size corresponding to reporting parameter #i included in the measurement report related to event #3, the payload size corresponding to reporting parameter #i included in the measurement report related to event #4, and the payload size corresponding to reporting parameter #j.

[0296] If event #1 and event #2 among events #1 to #4 occur, the first information sent by the terminal device can be as shown in Table 3, that is, the reporting parameter #g is carried on the public field #1, the reporting parameter #h is carried on the non-public field #1, and the non-public field #2 to the non-public field #4 are predefined values, for example, filled with all 0s.

[0297] Table 3

[0298] Optionally, if the first information includes multiple fields, the multiple fields are arranged in a predefined or preconfigured order. In other words, the terminal device reports the public reporting parameters and / or non-public reporting parameters included in the measurement report related to the event in a predefined or preconfigured order.

[0299] Format 2: the first information includes at least one event field.

[0300] At least one event field corresponds to X events. For example, at least one event field corresponds to X events one-to-one. Taking event field #1 in the at least one event field as an example, event field #1 is used to carry a measurement report related to the event corresponding to event field #1. In other words, the payload size of event field #1 is the payload size corresponding to the measurement report related to the event corresponding to event field #1. It should be noted that the event field may also be named by other names, and this application does not limit this.

[0301] It should be understood that if the events occurring among the X events include the event corresponding to event field #1, then the event field #1 included in the first information carries the measurement report related to the event corresponding to event field #1. If the events occurring among the X events do not include the event corresponding to event field #1, then the event field #1 included in the first information is a predefined value, for example, each bit of the event field #1 included in the first information is filled with 0. For example, the X events are event #1, event #2, ..., event #X, and the events occurring among the X events are events other than event #2. Then the first information sent by the terminal device can be as shown in Table 4, that is, event field #1 carries the measurement report related to event #1, event #3 carries the measurement report related to event #3, ..., event field #X carries the measurement report related to event #X, and event field #2 is a predefined value, for example, filled with all 0s.

[0302] Table 4

[0303] In summary, the payload size of the first information is the sum of the payload sizes corresponding to the measurement reports related to the X events. For example, if the X events are event #1, event #2, ..., event #X, event #1, event #2, ..., and the payload sizes corresponding to the measurement reports related to event #X are P1, P2, ..., PX, respectively, then the payload size of the first information is (P1 + P2 + ... + PX).

[0304] Optionally, if the first information includes multiple event fields, the multiple event fields are arranged in a predefined or preconfigured first order. In other words, the terminal device reports measurement reports related to different events in a predefined or preconfigured first order. The predefined or preconfigured first order is one of the following: in descending order of the indexes of the multiple events, in descending order of the indexes of the multiple events, or in descending order of the priorities of the multiple events.

[0305] In an embodiment of the present application, a terminal device can perform event-triggered reporting, thereby avoiding the terminal device from reporting invalid measurement reports to a network device. In addition, the terminal device can report measurement reports related to one or more events that have occurred using a first message in a predefined format, thereby avoiding resource waste caused by allocating corresponding reporting resources for each event when the terminal device supports or is configured with multiple events.

[0306] It can be understood that some optional features in the various embodiments of the present application may not depend on other features in certain scenarios, and may also be combined with other features in certain scenarios, without limitation.
