Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of communication, and in particular to a method for sending a beam report, a device, a storage medium and a program product. BACKGROUND
[0002] In a conventional beam management process, a network device (NW) can configure / activate frequent periodic or semi-persistent beam reporting (e.g., N best beams and their corresponding L1-RSRP) or trigger frequent aperiodic beam reporting in order to obtain the best / preferred beam for data / control transmission in a timely manner. However, this will obviously result in a large uplink reporting overhead and control signaling overhead. Since the user equipment (UE) knows more about the beam quality change, the NW may not be able to determine when to trigger the aperiodic beam reporting. With the help of the UE-initiated / event-driven (UEI / ED) beam reporting, the NW can update the link / beam quality for inter-UE communication in a timely manner without consuming excessive resources and power consumption, and thus the UEI / ED beam reporting method is proposed. The beam reporting process initiated by the UE can provide beam reporting in a more timely manner while reducing the reporting overhead. Therefore, how to reasonably define the event and efficiently send the beam report is crucial in the UEI / ED beam management.
[0003] In one related technology, the UEI / ED beam management has introduced Event-7 for updating the activated TCI state. The triggering feature of Event-7 is that the quality of at least one new beam reaches a threshold (better than the Qth best quality reference signal RS derived from the activated transmission configuration indication TCI state), and the UE will initiate the Event-7 beam report to indicate that there is a better TCI state in the new beam, and the currently activated TCI state needs to be updated. In the current discussion, it has been agreed that Event-7 does not have special requirements and should reuse the reporting format of Event-2 as much as possible to reduce complexity.
[0004] However, the network device cannot determine the difference in the validity of the activated TCI state through the report when the related technology reuses the reporting format of Event-2, and cannot perform scheduling according to the difference in the TCI state. SUMMARY
[0005] Embodiments of the present application provide a method for sending a beam report, a device, a storage medium and a program product, which are applied to the technical field of communication.
[0006] In a first aspect, the embodiments of the present application provide a method for sending a beam report, which is applied to a terminal device, and the method comprises:
[0007] detect quality indicators of each candidate beam in the candidate beam set, and compare the quality indicators with a quality indicator of a target beam, wherein the target beam is a beam corresponding to a Q-th activated transmission configuration indication (TCI) state in an activated TCI state set;
[0008] if it is detected that a quality indicator of at least one candidate beam in the candidate beam set exceeds the quality indicator of the target beam, determine quantity information of candidate beams whose quality indicators exceed the quality indicator of the target beam, and ordering information of beams corresponding to the activated TCI state set according to quality indicators;
[0009] generate a beam report, wherein the beam report includes the quantity information and the ordering information, and identifiers and quality indicators of each candidate beam in the candidate beam set;
[0010] send the beam report to a network device.
[0011] The method for sending a beam report provided in the present application enables the network device to determine candidate beams triggering Event-7 and beams to be replaced in the activated TCI state set, so that the TCI state can be updated more accurately, and the reliability of the activated TCI state is improved.
[0012] In a possible implementation, the quantity information of candidate beams whose quality indicators exceed the quality indicator of the target beam is determined by:
[0013] determining a target bit length of the quantity information according to a quantity of candidate beams included in the beam report;
[0014] converting the quantity of candidate beams whose quality indicators exceed the quality indicator of the target beam into an encoding of the target bit length as the quantity information.
[0015] That is, the target bit length of the quantity information of candidate beams whose quality indicators exceed the quality indicator of the target beam (a beam corresponding to a Q-th activated TCI state in the activated TCI state set) is determined by the terminal device according to the quantity of candidate beams included in the beam report, that is, the quantity information is encoded into the target bit length, and the network device can determine candidate beams whose quality indicators exceed the quality indicator of the target beam according to the encoding of the quantity information of the target bit length, in combination with the identifiers and quality indicators of each candidate beam in the candidate beam set included in the beam report, that is, candidate beams triggering Event-7, which reduces the data quantity compared with the prior art in which 1 bit is added to indicate each beam.
[0016] In a possible implementation, before determining the target bit length of the quantity information according to the quantity of candidate beams included in the beam report, the method further includes:
[0017] receiving a first configuration instruction of the network device, and configuring the quantity of candidate beams included in the beam report according to the first configuration instruction.
[0018] In a possible implementation, determining the ordering information of the beams corresponding to the set of activated TCI states according to the quality indicators includes:
[0019] encoding the index numbers of the beams corresponding to the set of activated TCI states;
[0020] ordering the encoding of the beams corresponding to the set of activated TCI states according to the order of the quality indicators of the beams corresponding to the set of activated TCI states, to obtain the ordering information.
[0021] That is, the terminal device can encode the ordering information of the beams corresponding to the set of activated TCI states according to the quality indicators to reduce the data quantity.
[0022] In a possible implementation, the ordering information of the beams corresponding to the set of activated TCI states is obtained by ordering the encoding of the beams corresponding to the set of activated TCI states according to the order of the quality indicators of the beams corresponding to the set of activated TCI states, including:
[0023] ordering the encoding of all the beams corresponding to the set of activated TCI states according to the order of the quality indicators of the beams corresponding to the set of activated TCI states, to obtain the ordering information.
[0024] That is, the terminal device adds the ordering information of all the beams corresponding to the set of activated TCI states to the beam report, so that the network device can learn the quality conditions of all the beams corresponding to the set of activated TCI states, facilitating subsequent scheduling.
[0025] In a possible implementation, the ordering information of the beams corresponding to the set of activated TCI states is obtained by ordering the encoding of the beams corresponding to the set of activated TCI states according to the order of the quality indicators of the beams corresponding to the set of activated TCI states, including:
[0026] ordering the encoding of a preset quantity of beams corresponding to the set of activated TCI states with the worst quality indicators according to the order of the quality indicators of the beams corresponding to the set of activated TCI states, to obtain the ordering information.
[0027] That is, the terminal device does not need to report all the sorting information of the beams corresponding to the activated TCI state set, but only reports the sorting information of a preset number of beams with the worst quality indicators in the beams corresponding to the activated TCI state set in the beam report, which can reduce the data amount of the sorting information.
[0028] In a possible implementation, the encoding of the beams corresponding to the activated TCI state set is sorted according to the order of the quality indicators of the beams corresponding to the activated TCI state set, to obtain the sorting information, including:
[0029] The encoding of the beams corresponding to the activated TCI states after the Rth in the quality indicator ranking in the activated TCI state set is sorted according to the order of the quality indicators of the beams corresponding to the activated TCI state set, to obtain the sorting information.
[0030] That is, the terminal device does not need to report all the sorting information of the beams corresponding to the activated TCI state set, but only reports the sorting information of the beams after the Rth in the quality indicator ranking in the beams corresponding to the activated TCI state set in the beam report, which can reduce the data amount of the sorting information.
[0031] In a possible implementation, the encoding of the beams corresponding to the activated TCI state set is sorted according to the order of the quality indicators of the beams corresponding to the activated TCI state set, to obtain the sorting information, including:
[0032] The target number of beams included in the sorting information is determined according to the number of candidate beams with quality indicators exceeding that of the target beam.
[0033] The encoding of the beams corresponding to the target number of activated TCI states with the worst quality indicators in the activated TCI state set is sorted according to the order of the quality indicators of the beams corresponding to the activated TCI state set, to obtain the sorting information.
[0034] That is, the number of beams included in the sorting information adopts a dynamic number, the target number of beams included in the sorting information is determined according to the number of candidate beams with quality indicators exceeding that of the target beam, and only the sorting information of the target number of beams with the worst quality indicators in the beams corresponding to the activated TCI state set is reported in the beam report, which has higher flexibility and practicability.
[0035] In a possible implementation, the target number of beams included in the sorting information is determined according to the number of candidate beams with quality indicators exceeding that of the target beam, including:
[0036] The number of candidate beams with quality indicators exceeding that of the target beam is determined as the target number.
[0037] That is, the terminal device determines the number of candidate beams exceeding the quality indicator of the target beam as the target number, that is, the target number of beams included in the sorting information is equal to the number of candidate beams exceeding the quality indicator of the target beam, so that in a relatively ideal state, the network device can replace the target number of beams with the worst quality indicators in the corresponding beams in the activated TCI state set with the candidate beams exceeding the quality indicator of the target beam, to accurately update the TCI state.
[0038] In a possible implementation, the target number of beams included in the sorting information is determined according to the number of candidate beams exceeding the quality indicator of the target beam, including:
[0039] If the number of candidate beams exceeding the quality indicator of the target beam is greater than or equal to M-Q, the target number is determined as M-Q, where M is the number of beams corresponding to all activated TCI states in the activated TCI state set; or
[0040] If the number of candidate beams exceeding the quality indicator of the target beam is less than M-Q, the number of candidate beams exceeding the quality indicator of the target beam is determined as the target number.
[0041] That is, in the case where the number of candidate beams exceeding the quality indicator of the target beam has exceeded the number of beams ranked after the Qth in the activated TCI state set, only the sorting information of the beams ranked after the Qth in the activated TCI state set needs to be reported, that is, the target number is equal to M-Q; if the number of candidate beams exceeding the quality indicator of the target beam is less than M-Q, the number of candidate beams exceeding the quality indicator of the target beam can be determined as the target number, that is, the target number of beams included in the sorting information is equal to the number of candidate beams exceeding the quality indicator of the target beam, so that in a relatively ideal state, the network device can replace the target number of beams with the worst quality indicators in the corresponding beams in the activated TCI state set with the candidate beams exceeding the quality indicator of the target beam, to accurately update the TCI state.
[0042] In a possible implementation, after the beam report is sent to the network device, the method further includes:
[0043] receiving a TCI state set update instruction sent by the network device according to the beam report, where the TCI state set update instruction includes an updated activated TCI state set determined by the network device according to the beam report;
[0044] replacing the activated TCI state set with the updated activated TCI state set.
[0045] That is, after receiving the beam report, the network device can make more accurate TCI activation and scheduling update according to the beam report.
[0046] In a third aspect, the embodiments of the present application provide a beam switching method based on a beam report, applied to a network device, the method comprising:

[0048] determining, according to the beam report, candidate beams whose quality indicators exceed that of the target beam and beams in the activated TCI state set to be replaced.
[0049] The beam switching method based on a beam report provided by the embodiments of the present application can determine, by a network device parsing a beam report, candidate beams whose quality indicators exceed that of a target beam and beams in an activated TCI state set to be replaced, for subsequent accurate TCI activation and scheduling update.
[0050] In a possible implementation, the method further comprises:
[0051] determining an updated activated TCI state set according to the candidate beams whose quality indicators exceed that of the target beam and the beams in the activated TCI state set to be replaced;
[0052] sending a TCI state set update instruction to the terminal device, the TCI state set update instruction comprising the updated activated TCI state set.
[0053] That is, the network device can update the activated TCI state set and send it to the terminal device for subsequent beam management; after receiving the TCI state set update instruction, the terminal device can determine a target candidate beam of a to-be-activated TCI state and a beam in the activated TCI state set to be replaced, activate the TCI state of the target candidate beam of the to-be-activated TCI state, and deactivate the TCI state of the beam in the activated TCI state set to be replaced.
[0054] In a possible implementation, determining the updated activated TCI state set according to the candidate beams whose quality indicators exceed that of the target beam and the beams in the activated TCI state set to be replaced comprises:
[0055] replace the TCI state of the to-be-replaced beam in the activated TCI state set with the TCI state of the candidate beam whose quality index exceeds that of the target beam.
[0056] That is, the network device replaces the TCI state of the to-be-replaced beam in the activated TCI state set with the TCI state of the candidate beam whose quality index exceeds that of the target beam, and obtains the updated activated TCI state set through the predetermined replacement rule.
[0057] In a possible implementation, the updated activated TCI state set is determined according to the candidate beam whose quality index exceeds that of the target beam and the to-be-replaced beam in the activated TCI state set, and includes:

[0084] In order to clearly describe the technical solutions of the embodiments of the present application, the following briefly introduces some terms and technologies involved in the embodiments of the present application:
[0085] 1. Terminal device
[0086] The terminal device of the embodiments of the present application can include handheld devices, vehicle-mounted devices, etc. with beam management, transmission beam heightening functions. For example, some terminal devices are: mobile phones, tablet computers, palm computers, notebook computers, mobile internet devices (MID), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote medical surgery, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart city, wireless terminals in smart home, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, terminal devices in 5G networks or terminal devices in future evolved public land mobile networks (PLMN), etc. The embodiments of the present application are not limited thereto.
[0087] As an example but not limitation, in the embodiments of the present application, the terminal device can also be a wearable device. The wearable device can also be referred to as a wearable smart device, which is a general term for devices that are designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes. The wearable device is a portable device that is directly worn on the body or integrated into the clothes or accessories of the user. The wearable device is not only a hardware device, but also has powerful functions through software support and data interaction and cloud interaction. The general wearable smart device includes devices with full functions and large sizes, which can realize complete or partial functions without relying on a smart phone, such as smart watches or smart glasses, and devices that focus on a certain application function and need to be used in cooperation with other devices, such as smart phones, such as various smart wristbands and smart jewelry for monitoring vital signs.
[0088] In addition, in the embodiments of the present application, the terminal device can also be a terminal device in an Internet of Things (IoT) system. The IoT is an important part of the future development of information technology, and its main technical feature is to connect objects through communication technology and network to realize the intelligent network of man-machine interconnection and object-object interconnection.
[0089] The terminal device in the embodiments of the present application can also be referred to as a user equipment (UE), a mobile station (MS), a mobile terminal (MT), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile terminal, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device, etc.
[0090] 2. Network device:
[0091] In the embodiments of the present application, the network device (Network, NW) can be any kind of device with wireless transceiving function. The device includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, Home evolved NodeB, or Home Node B, HNB), baseband unit (BBU), access point (AP) in a Wireless Fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP), etc., and can also be a gNB or a transmission point (TRP or TP) in a 5G, such as an NR, system, one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc.
[0092] In some deployments, a gNB can include a centralized unit (CU) and a DU. The gNB can also include an active antenna unit (AAU). The CU implements part of the functions of the gNB, and the DU implements part of the functions of the gNB, for example, the CU is responsible for processing non-real-time protocols and services, implementing radio resource control (RRC), functions of the packet data convergence protocol (PDCP) layer. The DU is responsible for processing the physical layer protocol and real-time services, implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer and the physical (PHY) layer. The AAU implements part of the physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, therefore, under this architecture, high layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It can be understood that the network device can be a device including one or more of the CU node, the DU node, and the AAU node. In addition, the CU can be divided into a network device in the radio access network (RAN), or can be divided into a network device in the core network (CN), which is not limited in the present application.
[0093] The network device provides services for a cell, and the terminal device communicates with the cell through the transmission resource (for example, frequency domain resource, or spectrum resource) allocated by the network device. The cell can belong to a macro base station (for example, a macro eNB or a macro gNB, etc.), or a base station corresponding to a small cell. The small cell here can include a metro cell, a micro cell, a pico cell, a femto cell, etc., which have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.
[0094] 3. TCI state:
[0095] TCI (Transmission Configuration Indicator) state is a key technology in 5G NR (New Radio), used to indicate how user equipment (UE) receives downlink reference signal (such as CSI-RS, SSB) or data transmission beam configuration information. Its core role is to optimize beam management and transmission efficiency by dynamically or semi-statically configuring UE's reception parameters. TCI state informs UE through RRC signaling (Radio Resource Control) or MAC-CE (Medium Access Control - Control Element) to explicitly indicate the quasi co-location (QCL) relationship between downlink channel / signal and specific reference signal (such as CSI-RS or SSB); help UE use the beam characteristics (such as time-frequency offset, spatial parameters) of known reference signal to receive data or control channel, reduce measurement complexity.
[0096] 4. Beam report:
[0097] Beam report is the process of UE feeding back optimal beam information to network device, used to support beamforming and beam management. Its core purpose is to help network device select the best transmission / reception beam to improve signal quality, reduce interference, and optimize network performance.
[0098] UE-initiated / Event-driven (UEI / ED) beam report is a beam report sent by UE to network device according to specific events or conditions, used to optimize beam management and improve network performance, reduce air interface signaling overhead.
[0099] 5. Event-7 (Event-7) is an event where the strongest cell on non-serving frequency becomes better than the threshold (StrongestCell on Non-Serving Frequency becomes Better than Threshold). The triggering feature of Event-7 is that the quality of at least one new beam reaches the threshold (better than the Qth best quality reference signal RS derived from the activated transmission configuration indicator TCI state). Event-2 (Event-2) is an event where the serving cell signal becomes worse than the threshold (ServingCell becomes Worse than Threshold). The triggering feature of Event-2 is that the signal quality (RSRP / RSRQ) of the current serving cell is lower than the threshold configured by the network device.
[0100] 6. RSRP (Reference Signal Receiving Power) is a key parameter for measuring wireless signal strength.
[0101] 7. CRI is a CSI-RS (Channel State Information Reference Signal) resource indicator, used to identify the optimal CSI-RS beam selected by the UE; SSBRI is a SSB (Synchronization Signal Block, i.e., SS / PBCH Block) resource indicator, used to identify the optimal SSB beam selected by the UE.

[0109] The use scenarios of the sending method of the beam report will be described below. Figure 1 As shown in FIG. 1, the communication system includes a terminal device 110 and a network device 120, and the network device 120 can send beams to the terminal device 110, the terminal device 110 can perform beam management, and send beam reports to the network device 120. Figure 1
[0110] In the traditional beam management process, the network device (NW) can configure / activate frequent periodic or semi-persistent beam reports (for example, N best beams and their corresponding L1-RSRP), or trigger frequent aperiodic beam reports, in order to obtain the best / preferred beam for data / control transmission in time. However, this will obviously cause large uplink report overhead and control signaling overhead. Since the user equipment (UE) knows more about the beam quality change, the NW may not be able to determine when to trigger the aperiodic beam report, and with the help of the UE-initiated / event-driven (UEI / ED) beam report, the NW can update the link / beam quality for inter-UE communication in time without consuming too much resource and power consumption, so the UEI / ED beam report mode is proposed. The beam report process initiated by the UE can provide beam report more timely, while reducing the report overhead. Therefore, how to reasonably define the event and efficiently send the beam report is crucial in the UEI / ED beam management.
[0111] In a related technology, the beam management of UE I / ED has introduced Event-7 for updating the activated TCI state. The triggering feature of Event-7 is that the quality of at least one new beam reaches a threshold (better than the Q-th best quality reference signal RS derived from the activated transmission configuration indication TCI state), and the UE initiates a beam report of Event-7 to indicate that there is a better TCI state in the new beam, and the currently activated TCI state needs to be updated. In the current discussion, it has been agreed that Event-7 does not have special requirements and should reuse the reporting format of Event-2 as much as possible to reduce complexity. Therefore, the existing Event-7 beam report is based on the reporting purpose of Event-2, and there are deficiencies in the application of Event-7. Therefore, the reporting format of Event-2 is optimized for Event-7. First, the "current beam" option in Event-2 is replaced by the RSRP value of the RS corresponding to the Q-th activated TCI state in the report of Event-7, which can be used to indicate which reporting beam triggered the instance of Event-7. Secondly, a 1-bit indication can be added to the reporting beam in the report of Event-7 to indicate whether the beam triggered the event. On the other hand, the state code point corresponding to the Q-th activated TCI state can be reported to specify the specific index of the "current beam" reported by Event-7.
[0112] In the beam management of UE I / ED, the feature of Event-7 triggering is that once the quality of at least one new beam reaches a threshold (better than the Q-th best quality RS derived from the activated TCI state), the UE initiates a beam report of Event-7, and the network device can update the TCI state of the UE according to the beam report. The existing Event-7 beam report format description (from 3GPP RAN1) is shown in Table 1 as follows:
[0113] Table 1:
[0114]
[0115] Where CRI or SSBRI is the top N beam index in the new beam set, N is configured by the RRC parameter, and the beam set is configured by "CSI reporting configuration". Differential L1-RSRP represents the difference between L1-RSRP #1. It can be seen that "current beam" in the Event-7 report content contains part of the beam information of the activated TCI state and the beam information corresponding to the potential activated TCI state.
[0116] If the RRC enables the "current beam", the UE multiplexes the "current beam" as the RSRP of the RS corresponding to the Q-th TCI in the beam report of Event-7, and the network device can implicitly infer the beam index of the triggering event in the reported beam according to the RSRP, thereby mapping to the TCI state of the candidate triggering beam; if the Event-7 beam report multiplexes the 1-bit indication about the triggering beam event in the Event-2 report, that is, each beam will increase a 1-bit indication bit, the network device can determine the beam index of the triggering event in the reported beam through the indication, thereby mapping to the TCI state of the candidate triggering beam.
[0117] However, the above scheme has problems in the face of the goal of updating the activated TCI state: multiplexing the beam report format of Event-2, the UE reports the beams in the new beam set, which is relatively independent of the beams corresponding to the activated TCI state, and the report can only determine which beams corresponding to the TCI state can be activated, and there is no indication of the validity of the activated TCI state in the consensus report structure, that is, the network device cannot determine the validity difference of the activated TCI state through the report, and cannot perform scheduling according to the TCI state difference.
[0118] In view of this, the embodiment of the present application provides a beam report sending method, and proposes the following scheme: adding quality ordering information of TCI code points in the Event-7 beam report, reporting the activated TCI state with poor quality and its order, so that the network device can determine the beam triggering Event-7 after receiving the beam report of Event-7, and can perform TCI scheduling update according to the quality order of the activated TCI.
[0119] The method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.
[0120] It should be understood that the following is only for the convenience of understanding and description, and the method provided by the embodiment of the present application is described in detail taking the interaction between the terminal device and the network device as an example.

For example, the execution subject of the method provided by the embodiments of the present application can be a terminal device, or a functional module in the terminal device that can invoke and execute a program.
[0122] Figure 2 FIG. 1 is a schematic flowchart of a method for transmitting a beam report provided by the embodiments of the present application, which is shown from the perspective of device interaction. As shown in FIG. 1, the method for transmitting a beam report can include the following steps. Figure 2
[0123] S201, the terminal device detects the quality indicators of each candidate beam in the candidate beam set, and compares the quality indicators with the quality indicator of the target beam, wherein the target beam is the beam corresponding to the Q-th activated TCI state in the activated TCI state set.
[0124] In the embodiments of the present application, the terminal device detects the quality indicators of each candidate beam in the candidate beam set (i.e., the new beam set), and compares the quality indicators with the quality indicator of the target beam corresponding to the Q-th activated TCI state in the activated TCI state set, so as to determine whether each candidate beam triggers Event-7.
[0125] S202, if the terminal device detects that the quality indicator of at least one candidate beam in the candidate beam set exceeds the quality indicator of the target beam, the terminal device determines the quantity information of the candidate beams whose quality indicators exceed the quality indicator of the target beam, and the ordering information of the beams corresponding to the activated TCI state set according to the quality indicators.
[0126] In the embodiments of the present application, if at least one candidate beam in the candidate beam set exceeds the beam corresponding to the Q-th activated TCI state, it is determined that the at least one candidate beam triggers Event-7. The quantity information of the candidate beams whose quality indicators exceed the quality indicator of the target beam, i.e., the quantity information of the candidate beams triggering Event-7, can be determined, and the ordering information of the beams corresponding to the activated TCI state set according to the quality indicators also needs to be determined.
[0127] S203, the terminal device generates a beam report; wherein the beam report includes the identifiers and quality indicators of each candidate beam in the candidate beam set, the quantity information, and the ordering information.
[0128] In the embodiments of the present application, when the terminal device generates the beam report of Event-7, the terminal device can include the identification and quality indicators of each candidate beam in the beam report (the same as the Event-7 beam report in the prior art), and further include the number information of the candidate beams exceeding the quality indicator of the target beam, and the sorting information of the beams corresponding to the activated TCI state set according to the quality indicators. As an example, the beam report format of the embodiments of the present application is described as shown in Table 2.
[0129] Table 2:
[0130]
[0131] In the table, CRI or SSBRI #1~ CRI or SSBRI #N are the identifications of each candidate beam, L1-RSRP #1, Differential L1-RSRP #2~ Differential L1-RSRP #N represent the quality indicators of each candidate beam, the number information of the beams exceeding the Q-th activated TCI corresponding to the quality indicators is the number information of the beams exceeding the Q-th activated TCI corresponding to the quality indicators in CRI or SSBRI #1~ CRI or SSBRI #N, and the sorting information of the beams corresponding to the activated TCI state set according to the quality indicators can be the sorting information of all beams or part of beams corresponding to the activated TCI state set according to the quality indicators. If it is the sorting information of part of beams corresponding to the activated TCI state set according to the quality indicators, it can be specifically the sorting information of the worst part of beams according to the quality indicators.
[0132] It should be noted that the number information of the candidate beams exceeding the quality indicator of the target beam and the sorting information of the beams corresponding to the activated TCI state set according to the quality indicators can be encoded in any feasible manner, and the information obtained after encoding is added to the beam report of Event-7.
[0133] In S204, the terminal device sends the beam report to the network device.
[0134] In the embodiments of the present application, after the terminal device generates the beam report of Event-7, the terminal device sends the beam report to the network device.
[0135] Further, the network device can determine the candidate beams (candidate beams triggering Event-7) whose quality indicators exceed the quality indicator of the target beam according to the identifiers and quality indicators of the candidate beams in the candidate beam set included in the beam report and the number information of the candidate beams whose quality indicators exceed the quality indicator of the target beam, wherein the identifiers and quality indicators of the candidate beams can be sorted according to the quality indicators, and the candidate beams corresponding to the number information of the candidate beams with the highest quality indicators in the sorting are determined as the candidate beams (candidate beams triggering Event-7) whose quality indicators exceed the quality indicator of the target beam; in addition, the network device can determine one or more beams with poor quality in the activated TCI state set as the to-be-replaced beams according to the sorting information of the beams in the activated TCI state set according to the quality indicators, and can make more accurate TCI activation and scheduling update according to the candidate beams whose quality indicators exceed the quality indicator of the target beam and the to-be-replaced beams in the activated TCI state set.
[0136] In some embodiments, the network device can send a TCI state set update instruction generated according to the beam report to the terminal device, wherein the TCI state set update instruction includes the updated activated TCI state set determined by the network device according to the beam report; the terminal device can replace the activated TCI state set with the updated activated TCI state set to update the TCI state set, and then can perform beam management based on the updated activated TCI state set, such as beam switching and other operations.
[0137] Specifically, after receiving the TCI state set update instruction, the terminal device can cover the updated activated TCI state set with the activated TCI state set, and can determine the target candidate beam of the to-be-activated TCI state and the to-be-replaced beam in the activated TCI state set, activate the TCI state of the target candidate beam of the to-be-activated TCI state, and deactivate the TCI state of the to-be-replaced beam in the activated TCI state set to update the activated TCI state set.
[0138] The method for sending a beam report provided in the embodiments of the present application comprises the following steps: a terminal device detects the quality indicators of each candidate beam in a candidate beam set, and compares the quality indicators with a target beam, wherein the target beam is a beam corresponding to a Qth activated transmission configuration indication (TCI) state in an activated TCI state set in terms of quality indicator ranking; if it is detected that the quality indicator of at least one candidate beam in the candidate beam set exceeds the quality indicator of the target beam, the terminal device determines the quantity information of the candidate beams whose quality indicators exceed the quality indicator of the target beam, and the ordering information of the beams corresponding to the activated TCI state set in terms of quality indicator; generates a beam report; wherein the beam report comprises the identifiers and quality indicators of each candidate beam in the candidate beam set, the quantity information, and the ordering information; and sends the beam report to a network device. In the embodiments of the present application, the quantity information of the candidate beams whose quality indicators exceed the quality indicator of the target beam, and the ordering information of the beams corresponding to the activated TCI state set in terms of quality indicator are added in the beam report by the terminal device, so that the network device can clearly determine the candidate beams triggering Event-7 and the beams to be replaced in the activated TCI state set, and thus the TCI state can be updated more accurately, and the reliability of the subsequent activated TCI state can be ensured.
[0139] In some embodiments, when the terminal device determines the quantity information of the candidate beams whose quality indicators exceed the quality indicator of the target beam, S202 can specifically comprise the following steps:
[0140] determining the target bit length of the quantity information according to the quantity of the candidate beams included in the beam report;
[0141] converting the quantity of the candidate beams whose quality indicators exceed the quality indicator of the target beam into the encoding of the target bit length as the quantity information.
[0142] In the embodiments of the present application, the quantity of the candidate beams included in the beam report is N, for example, in the beam report format shown in Table 2, CRI or SSBRI #1~CRI or SSBRI #N, a total of N candidate beams are included. The quantity N of the candidate beams included in the beam report can be configured by the network device, for example, the network device sends a first configuration instruction to the terminal device, wherein the first configuration instruction comprises the quantity of the candidate beams included in the beam report, so as to realize the configuration of the quantity N of the candidate beams included in the beam report by the network device, wherein the first configuration instruction can be an RRC instruction or any other feasible instruction; of course, the configuration can also be realized by any other feasible means.
[0143] The terminal device can determine a target bit length of quantity information of candidate beams for representing a quality index of a target beam (a beam corresponding to a Q-th activated TCI state in the activated TCI state set) according to a quantity N of candidate beams included in the beam report, that is, how many bits are used to represent the quantity information, and then encode the quantity information into the target bit length.
[0144] For example, when N = 1, no consideration is needed, that is, the candidate beam included in the beam report is the beam triggering Event-7, and the quantity information can not be added in the beam report; when N = 2, 1 bit can be used to represent the quantity information, 0 represents 1, and 1 represents 2; when N = 3-4, 2 bits can be used to represent the quantity information, "00" represents 1, "01" represents 2, and so on to "11" representing 4; when N = 5-8, similarly, 3 bits can be used to represent, "000" represents 1, and so on to "111" representing 8. Through this scheme, only the target bit length is needed, and the network device can determine the candidate beam for representing the quality index of the target beam according to the encoding of the quantity information of the target bit length, in combination with the identification and quality index of each candidate beam in the candidate beam set included in the beam report, that is, the candidate beam triggering Event-7, which reduces the data quantity compared with the prior art of adding 1 bit indication bit for each beam.
[0145] In some embodiments, when the terminal device determines the ordering information of the activated TCI state set corresponding beams according to the quality index in S202, the specific operations can include:
[0146] encoding the index number of the activated TCI state set corresponding beams;
[0147] ordering the encoding of the activated TCI state set corresponding beams according to the order of the quality index of the activated TCI state set corresponding beams to obtain the ordering information.
[0148] In the embodiment of the present application, the beams corresponding to the activated TCI state set can be directly sorted according to the quality indicators, but considering that the index numbers of the beams can be long, resulting in a large amount of data of the sorting information of the beams corresponding to the activated TCI state set according to the quality indicators, therefore, in the embodiment of the present application, the sorting information of the beams corresponding to the activated TCI state set according to the quality indicators can be encoded to reduce the amount of data. Specifically, the index numbers of the beams corresponding to the activated TCI state set can be encoded, and the encoding rule is known to the terminal device and the network device, that is, the terminal device can encode the index numbers of the beams according to the encoding rule, and the network device can also decode the index numbers of the beams based on the encoding rule after obtaining the encoding of the index numbers of the beams, so that only the sorting information of the encoding of the index numbers of the beams corresponding to the activated TCI state set needs to be added in the beam report, and the network device can obtain the sorting information of the beams corresponding to the activated TCI state set according to the quality indicators. The encoding rule can adopt any feasible manner as long as it can reduce the amount of data of the sorting information.
[0149] In an optional manner, a specific length of binary encoding manner can be adopted, wherein the length of the binary encoding can be determined by the number of beams corresponding to the activated TCI state set, for example, if the number of beams corresponding to the activated TCI state set is 8, a 3-bit binary encoding manner can be adopted to represent the 8 beams corresponding to the activated TCI state set by 000-111, the index numbers of the 8 beams corresponding to the activated TCI state set can be mapped to 000-111, and the mapping manner can be to map the index numbers of the 8 beams corresponding to the activated TCI state set from small to large to 000-111. As an example shown in FIG. 8, the network device can configure the index numbers of the TCI states as 0-127, and the index numbers of the 8 beams corresponding to the activated TCI state set are 9-16, the smallest index number 9 can be mapped to 000, the index number 10 can be mapped to 001, and so on until the index number 16 is mapped to 111. Of course, the index numbers of the 8 beams corresponding to the activated TCI state set can not necessarily be continuous, but the mapping manner from small to large can still be followed, and the network device knows the index numbers of the beams corresponding to the activated TCI state set, and also follows the mapping manner from small to large, and can be mapped back to the index numbers from the binary encoding. Figure 3
[0150] Further, the terminal device can sort the encoding of the beams corresponding to the activated TCI state set according to the size of the quality indicators as the sorting information. For example, the indexes of the beams corresponding to the activated TCI states with poor quality determined to be reported in a certain measurement are sorted as 16 > 14 > 15, where the index 14 corresponds to “101”, the index 15 corresponds to “110”, and the index 16 corresponds to “111”. Therefore, the sorting information is (111 101 110), which is added to the beam report. The network device can determine the index of the beam corresponding to the activated TCI state as 16 > 14 > 15 by decoding the sorting information.
[0151] It should be noted that the mapping manner described above can also use other mapping manners, for example, the index number is mapped to the binary code from large to small, or other feasible mapping manners can be used, which are not limited in the embodiments of the present application.
[0152] In some embodiments, the sorting information of the beams corresponding to the activated TCI state set according to the quality indicators can be the sorting information of all beams or part of beams corresponding to the activated TCI state set according to the quality indicators. If it is the sorting information of part of beams corresponding to the activated TCI state set according to the quality indicators, it can be specifically the sorting information of the part of beams with the worst quality according to the quality indicators. Several different ways are provided as follows:
[0153] Way one: the encoding of all beams corresponding to the activated TCI states in the activated TCI state set is sorted according to the order of the quality indicators of the beams corresponding to the activated TCI state set, to obtain the sorting information.
[0154] In way one, the sorting information of all beams corresponding to the activated TCI state set is added to the beam report. In the case of encoding the index of the beam corresponding to the activated TCI state, the sorting of the encoding of all beams corresponding to the activated TCI states in the activated TCI state set is added to the beam report. In this way, the network device can obtain the quality condition of all beams corresponding to the activated TCI state set, which is convenient for subsequent scheduling.
[0155] Way two: the encoding of the pre-set number of beams corresponding to the activated TCI states with the worst quality indicators in the activated TCI state set is sorted according to the order of the quality indicators of the beams corresponding to the activated TCI state set, to obtain the sorting information.
[0156] In the second mode, a preset number L can be pre-configured, L is a fixed number, and only the ranking information of L beams with the worst quality indicators in the activated TCI state set corresponding to the beams is reported in the beam report, that is, the ranking information of the L beams with the worst quality indicators. In the case of encoding the index numbers of the beams corresponding to the activated TCI states, the encoding of the L beams corresponding to the activated TCI states with the worst quality indicators in the activated TCI state set can be sorted and added to the beam report. The preset number L can be configured by the network device through a specific instruction, and the latter can be configured through other modes, which is not limited in the embodiments of the present application. The preset number L needs to be less than the number of beams corresponding to the activated TCI state set. Through the second mode, all the ranking information of the beams corresponding to the activated TCI state set does not need to be reported, and the data amount of the ranking information can be reduced.
[0157] The third mode: according to the order of the quality indicators of the beams corresponding to the activated TCI state set, the encoding of the beams corresponding to the activated TCI states after the Rth in the ranking of the quality indicators in the activated TCI state set is sorted to obtain the ranking information.
[0158] In the third mode, similar to the second mode, a parameter also needs to be pre-configured, that is, a preset ranking R, and only the ranking information of the beams after the Rth in the ranking of the quality indicators in the activated TCI state set corresponding to the beams in the activated TCI state set is reported in the beam report. In the case of encoding the index numbers of the beams corresponding to the activated TCI states, the encoding of the beams corresponding to the activated TCI states after the Rth in the ranking of the quality indicators in the activated TCI state set can be sorted and added to the beam report. The preset ranking R can be configured by the network device through a specific instruction, and the latter can be configured through other modes, which is not limited in the embodiments of the present application. R also needs to be less than the number of beams corresponding to the activated TCI state set. Optionally, the preset ranking R can be reused Q, that is, R can be equal to Q. Through the third mode, all the ranking information of the beams corresponding to the activated TCI state set does not need to be reported, and the data amount of the ranking information can be reduced.
[0159] The fourth mode: according to the number of candidate beams exceeding the quality indicators of the target beams, the target number of beams included in the ranking information is determined; according to the order of the quality indicators of the beams corresponding to the activated TCI state set, the encoding of the target number of beams corresponding to the activated TCI states with the worst quality indicators in the activated TCI state set is sorted to obtain the ranking information.
[0160] In the fourth mode, a dynamic number can be used, the target number K of beams included in the sorting information is determined according to the number of candidate beams exceeding the quality indicator of the target beam, and then the sorting information of the K beams with the worst quality indicators in the corresponding beams in the activated TCI state set is reported in the beam report, that is, the sorting information of the K beams with the worst quality indicators in the corresponding beams in the activated TCI state set is reported in the beam report, and in the case of encoding the index number of the beams corresponding to the activated TCI state, the encoding of the K beams corresponding to the activated TCI state with the worst quality indicators in the activated TCI state set is sorted and added to the beam report, which has high flexibility and practicability.
[0161] Optionally, the number of candidate beams exceeding the quality indicator of the target beam can be determined as the target number, that is, the target number of beams included in the sorting information is equal to the number of candidate beams exceeding the quality indicator of the target beam, so that in an ideal state, the network device can replace the K beams with the worst quality indicators in the corresponding beams in the activated TCI state set with the candidate beams exceeding the quality indicator of the target beam, and accurately update the TCI state.
[0162] Optionally, when the target number of beams included in the sorting information is determined according to the number of candidate beams exceeding the quality indicator of the target beam, if the number of candidate beams exceeding the quality indicator of the target beam is greater than or equal to M-Q, the target number is determined as M-Q, where M is the number of beams corresponding to all activated TCI states in the activated TCI state set; if the number of candidate beams exceeding the quality indicator of the target beam is less than M-Q, the number of candidate beams exceeding the quality indicator of the target beam is determined as the target number.
[0163] In this embodiment, if the number of candidate beams exceeding the quality indicator of the target beam is greater than or equal to M-Q, it means that the number of candidate beams exceeding the quality indicator of the target beam has exceeded the number of beams ranked after the Qth in the activated TCI state set, that is, even if all the beams ranked after the Qth in the activated TCI state set are replaced, there are still candidate beams exceeding the quality indicator of the target beam, so only the ranking information of the beams ranked after the Qth in the activated TCI state set needs to be reported, that is, the target number is equal to M-Q; if the number of candidate beams exceeding the quality indicator of the target beam is less than M-Q, the number of candidate beams exceeding the quality indicator of the target beam can be determined as the target number, that is, the target number of beams included in the ranking information is equal to the number of candidate beams exceeding the quality indicator of the target beam, so in an ideal state, the network device can replace the K beams with the worst quality indicators in the activated TCI state set with the candidate beams exceeding the quality indicator of the target beam, to achieve accurate updating of the TCI state.
[0164] Of course, the number of beams included in the ranking information is not limited to being determined by the above-mentioned various manners, but can also be determined by any other feasible manner, which is not limited in the embodiments of the present application.
[0165] Figure 4 The schematic flowchart of the beam switching method based on the beam report provided by the embodiments of the present application is shown from the perspective of device interaction. As shown in Figure 4 , on the basis of Figure 2 , after the terminal device sends the beam report to the network device, the beam switching method based on the beam report can include:
[0166] S301, the network device receives the beam report sent by the terminal device, wherein the beam report includes: the identification and quality indicator of each candidate beam in the candidate beam set, the number information of candidate beams exceeding the quality indicator of the target beam, and the ranking information of the beams corresponding to the activated TCI state set according to the quality indicator, the target beam is the beam corresponding to the activated TCI state ranked Qth in the activated transmission configuration indication TCI state set according to the quality indicator;
[0167] S302, the network device determines the candidate beams exceeding the quality indicator of the target beam and the beams to be replaced in the activated TCI state set according to the beam report.
[0168] In the embodiments of the present application, the network device can determine the candidate beams (candidate beams triggering Event-7) whose quality indicators exceed the quality indicator of the target beam according to the identifiers and quality indicators of the candidate beams in the candidate beam set included in the beam report and the number information of the candidate beams whose quality indicators exceed the quality indicator of the target beam, wherein the identifiers and quality indicators of the candidate beams can be sorted according to the quality indicators, and the candidate beams corresponding to the number information of the candidate beams whose quality indicators exceed the quality indicator of the target beam in the sorting are determined as the candidate beams (candidate beams triggering Event-7) whose quality indicators exceed the quality indicator of the target beam. In addition, the network device can determine one or more beams with poor quality in the activated TCI state set as the to-be-replaced beams according to the sorting information of the beams in the activated TCI state set according to the quality indicators, and can determine the candidate beams whose quality indicators exceed the quality indicator of the target beam and the to-be-replaced beams in the activated TCI state set.
[0169] Further, the network device can perform TCI activation and scheduling update according to the candidate beams whose quality indicators exceed the quality indicator of the target beam and the to-be-replaced beams in the activated TCI state set.
[0170] In some embodiments, the network device can perform the following process:
[0171] S303, the network device determines an updated activated TCI state set according to the candidate beams whose quality indicators exceed the quality indicator of the target beam and the to-be-replaced beams in the activated TCI state set.
[0172] In the embodiments of the present application, the network device can replace at least one candidate beam whose quality indicator exceeds the quality indicator of the target beam with at least one to-be-replaced beam in the activated TCI state set, thereby determining an updated activated TCI state set.
[0173] Optionally, when the network device replaces the candidate beams whose quality indicators exceed the quality indicator of the target beam with the to-be-replaced beams in the activated TCI state set, the replacement rule can be any feasible rule, for example, replacing the best candidate beam whose quality indicator exceeds the quality indicator of the target beam with the worst to-be-replaced beam, replacing the second best candidate beam with the second worst to-be-replaced beam, and so on. Of course, other replacement rules can also be used, and the embodiments of the present application are not limited in this regard.
[0174] The specific replacement process can be that the network device replaces the TCI state of the to-be-replaced beam in the activated TCI state set with the TCI state of the candidate beam whose quality indicator exceeds the quality indicator of the target beam, thereby obtaining an updated activated TCI state set.
[0175] S304. The network device sends a TCI state set update instruction to the terminal device, where the TCI state set update instruction includes the updated active TCI state set.
[0176] In the embodiment of the present application, the network device can send the updated active TCI state set to the terminal device, which can be sent by any feasible instruction, denoted as a TCI state set update instruction. Optionally, the TCI state set update instruction can use MAC-CE signaling, or RRC signaling or other signaling, which is not limited in the embodiment of the present application.
