Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, storage medium, and program product for sending beam reports. Background Art

[0002] In traditional beam management procedures, the network equipment (NW) can configure / activate frequent periodic or semi-persistent beam reporting (e.g., N best beams and their corresponding L1-RSRPs) or trigger frequent aperiodic beam reporting to promptly obtain the optimal / preferred beam for data / control transmission. However, this obviously results in significant uplink reporting and control signaling overhead. Since the user equipment (UE) is more aware of beam quality changes, the NW may not be able to determine when to trigger aperiodic beam reporting. UE-initiated / event-driven (UEI / ED) beam reporting allows the NW to promptly update the link / beam quality for communications with the UE without consuming excessive resources and power. This is why UEI / ED beam reporting is proposed. This UE-initiated beam reporting process provides more timely beam reports while reducing reporting overhead. Therefore, properly identifying events and efficiently transmitting beam reports are crucial in UEI / ED beam management.

[0003] In a related technology, UEI / ED beam management introduces Event-7, which is used to update the activated Transmission Control Interface (TCI) status. Event-7 is triggered when 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 indicating the TCI status). The UE then initiates an Event-7 beam report, indicating that the new beam has a better TCI status and that the currently activated TCI status needs to be updated. Current discussions have determined that Event-7, unless specifically required, reuses the reporting format of Event-2 whenever possible to reduce complexity.

[0004] However, when the prior art reuses the report format of Event-2, the network device cannot determine the validity difference of the activated TCI status through the report, and cannot perform scheduling based on the TCI status difference. Summary of the Invention

[0005] The embodiments of the present application provide a beam report sending method, device, storage medium, and program product, which are applied in the field of communication technology.

[0006] In a first aspect, an embodiment of the present application provides a method for sending a beam report, which is applied to a terminal device. The method includes:

[0007] Detecting a quality indicator of each candidate beam in the candidate beam set and comparing it with a quality indicator of a target beam, where the target beam is the beam corresponding to the activated TCI state with the Qth highest quality indicator in the activated transmission configuration indicator TCI state set;

[0008] If it is detected that the quality index of at least one candidate beam in the candidate beam set exceeds the quality index of the target beam, then determining the number of candidate beams that exceed the quality index of the target beam and the sorting information of the beams corresponding to the activated TCI state set according to the quality index;

[0009] Generate a beam report; wherein the beam report includes an identifier and a quality indicator of each candidate beam in the candidate beam set, the quantity information, and the ranking information;

[0010] The beam report is sent to the network device.

[0011] The beam report sending method of the present application adds the number information of candidate beams that exceed the quality index of the target beam and the sorting information of the corresponding beams of the activated TCI state set according to the quality index in the beam report by the terminal device, so that the network device can clearly trigger the candidate beams of Event-7 and the beams to be replaced in the activated TCI state set, and then update the TCI status more accurately, ensuring that the subsequent activated TCI status has higher reliability.

[0012] In a possible implementation, determining the number of candidate beams exceeding a quality indicator of the target beam includes:

[0013] Determining, according to the number of candidate beams included in the beam report, a target bit length of the number information;

[0014] The number of candidate beams exceeding the quality indicator of the target beam is converted into a code of the target bit length as the quantity information.

[0015] That is to say, the terminal device can determine the target bit length of the quantity information of the candidate beams used to represent the quality index exceeding the target beam (the beam corresponding to the Q-th activated TCI state in the activated TCI state set) based on the number 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. The network device can determine the candidate beam used to represent the quality index exceeding the target beam based on the encoding of the quantity information of the target bit length, combined with the beam report including the identification and quality index of each candidate beam in the candidate beam set, that is, the candidate beam that triggers Event-7. Compared with the prior art of adding 1 bit indicator bit to each beam, the amount of data is reduced.

[0016] In a possible implementation, before determining the target bit length of the quantity information according to the number of candidate beams included in the beam report, the method further includes:

[0017] A first configuration instruction of the network device is received, and the number of candidate beams included in the beam report is configured according to the first configuration instruction.

[0018] In one possible implementation, determining the sorting information of beams corresponding to the activated TCI state set according to the quality indicator includes:

[0019] Encode the index number of the beam corresponding to the activated TCI state set;

[0020] According to the order of the quality indicators of the beams corresponding to the activated TCI state set, the codes of the beams corresponding to the activated TCI state set are sorted to obtain the sorting information.

[0021] That is to say, the terminal device can encode the beams corresponding to the activated TCI state set according to the sorting information of the quality indicators to reduce the amount of data.

[0022] In one possible implementation, sorting the codes of the beams corresponding to the activated TCI state set according to the order of the quality indicators of the beams corresponding to the activated TCI state set to obtain the sorting information includes:

[0023] According to the order of the quality indicators of the beams corresponding to the activated TCI state set, the codes of all the beams corresponding to the activated TCI states in the activated TCI state set are sorted to obtain the sorting information.

[0024] That is to say, the terminal device adds the sorting information of all beams corresponding to the activated TCI state set to the beam report, so that the network device can know the quality status of all beams corresponding to the activated TCI state set, which is convenient for subsequent scheduling.

[0025] In one possible implementation, sorting the codes of the beams corresponding to the activated TCI state set according to the order of the quality indicators of the beams corresponding to the activated TCI state set to obtain the sorting information includes:

[0026] According to the order of the quality indicators of the beams corresponding to the activated TCI state set, the codes of the beams corresponding to a preset number of activated TCI states with the worst quality indicators in the activated TCI state set are sorted to obtain the sorting information.

[0027] That is to say, the terminal device does not need to report all the sorting information of all beams corresponding to the activated TCI status set, but only reports the sorting information of a preset number of beams with the worst quality indicators in the activated TCI status set in the beam report, which can reduce the amount of data of the sorting information.

[0028] In one possible implementation, sorting the codes of the beams corresponding to the activated TCI state set according to the order of the quality indicators of the beams corresponding to the activated TCI state set to obtain the sorting information includes:

[0029] According to the order of the quality indicators of the beams corresponding to the activated TCI state set, the codes corresponding to the beams whose quality indicators in the activated TCI state set are ranked after R are sorted to obtain the sorting information.

[0030] That is to say, the terminal device does not need to report all the sorting information of all beams corresponding to the activated TCI status set, but only reports the sorting information of the beams whose quality indicators rank after R in the corresponding beams in the activated TCI status set in the beam report, which can reduce the amount of data of the sorting information.

[0031] In one possible implementation, sorting the codes of the beams corresponding to the activated TCI state set according to the order of the quality indicators of the beams corresponding to the activated TCI state set to obtain the sorting information includes:

[0032] determining a target number of beams included in the ranking information based on the number of candidate beams that exceed the quality indicator of the target beam;

[0033] According to the order of the quality indicators of the beams corresponding to the activated TCI state set, the codes of the beams corresponding to the target number of activated TCI states with the worst quality indicators in the activated TCI state set are sorted to obtain the sorting information.

[0034] That is to say, the number of beams included in the sorting information adopts a dynamic number, and the target number of beams included in the sorting information is determined according to the number of candidate beams whose quality indicators exceed the target beam. In the beam report, only the sorting information of the target number of beams with the worst quality indicators in the corresponding beams in the activated TCI state set is reported, which has high flexibility and practicality.

[0035] In a possible implementation, determining the target number of beams included in the ranking information according to the number of candidate beams that exceed the quality indicator of the target beam includes:

[0036] The number of candidate beams that exceeds the quality indicator of the target beam is determined as the target number.

[0037] That is to say, the terminal device determines the number of candidate beams that exceed the quality index 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 that exceed the quality index of the target beam. In this way, under relatively ideal conditions, the network device can replace the candidate beams that exceed the quality index of the target beam with the target number of beams with the worst quality index in the corresponding beams in the activated TCI state set, so as to accurately update the TCI status.

[0038] In a possible implementation, determining the target number of beams included in the ranking information according to the number of candidate beams that exceed the quality indicator of the target beam includes:

[0039] If the number of candidate beams that exceed the quality index of the target beam is greater than or equal to MQ, then the target number is determined to be MQ, 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 index of the target beam is less than MQ, the number of candidate beams exceeding the quality index of the target beam is determined as the target number.

[0041] That is to say, when the number of candidate beams whose quality indicators exceed the target beam has exceeded the number of beams whose quality indicators are ranked after Q in the activated TCI state set, it is only necessary to report the sorting information of the beams whose quality indicators are ranked after Q in the activated TCI state set, that is, the target number is equal to MQ; if the number of candidate beams whose quality indicators exceed the target beam is less than MQ, the number of candidate beams whose quality indicators exceed 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 whose quality indicators exceed the target beam. In this way, under relatively ideal conditions, the network device can replace the candidate beams whose quality indicators exceed the target beam with the target number of beams with the worst quality indicators in the corresponding beams in the activated TCI state set, so as to accurately update the TCI state.

[0042] In a possible implementation, after sending the beam report 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, wherein the TCI state set update instruction includes an updated activated TCI state set determined by the network device according to the beam report;

[0044] The activated TCI state set is replaced with the updated activated TCI state set.

[0045] That is to say, after receiving the beam report, the network device can make more accurate TCI activation and scheduling updates based on the beam report.

[0046] In a third aspect, an embodiment of the present application provides a beam switching method based on beam reporting, applied to a network device, the method comprising:

[0047] Receive a beam report sent by a terminal device, where the beam report includes: an identifier and quality indicator of each candidate beam in the candidate beam set, information about the number of candidate beams that exceed the quality indicator of the target beam, and ranking information of beams corresponding to the activated TCI state set according to the quality indicator, where the target beam is the beam corresponding to the activated TCI state with the Qth highest quality indicator in the activated transmission configuration indication TCI state set;

[0048] Based on the beam report, determine the candidate beams that exceed the quality index of the target beam and the beams to be replaced in the activated TCI state set.

[0049] The beam switching method based on beam reporting provided in the embodiment of the present application can determine the candidate beams that exceed the quality index of the target beam and the beams to be replaced in the activated TCI state set by parsing the beam report through the network device, so as to be used for subsequent precise TCI activation and scheduling updates.

[0050] In a possible implementation, the method further includes:

[0051] Determine an updated activated TCI state set based on the candidate beams that exceed the quality indicator of the target beam and the beams to be replaced in the activated TCI state set;

[0052] A TCI state set update instruction is sent to the terminal device, where the TCI state set update instruction includes an updated activated TCI state set.

[0053] That is to say, 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 the target candidate beam of the TCI state to be activated and the beam to be replaced in the activated TCI state set, activate the TCI state of the target candidate beam of the TCI state to be activated, and deactivate the TCI state of the beam to be replaced in the activated TCI state set.

[0054] In one possible implementation, determining an updated activated TCI state set based on the candidate beams exceeding the quality indicator of the target beam and the beams to be replaced in the activated TCI state set includes:

[0055] The TCI state of the candidate beam that exceeds the quality indicator of the target beam is used to replace the TCI state of the beam to be replaced in the activated TCI state set.

[0056] That is, the network device uses the TCI state of the candidate beam that exceeds the quality index of the target beam to replace the TCI state of the beam to be replaced in the activated TCI state set, and replaces it according to the predetermined replacement rule to obtain the updated activated TCI state set.

[0057] In one possible implementation, determining an updated activated TCI state set based on the candidate beams exceeding the quality indicator of the target beam and the beams to be replaced in the activated TCI state set includes:

[0058] Determine, based on beam scheduling conditions between the terminal device and other terminal devices, one or more target candidate beams in a to-be-activated TCI state from candidate beams that exceed a quality indicator of the target beam;

[0059] The TCI state of the target candidate beam is used to replace the TCI state of the beam to be replaced in the activated TCI state set.

[0060] That is to say, the network device determines the number of replacement beams from the candidate beams that exceed the quality index of the target beam based on the beam scheduling between the terminal device and other terminal devices, thereby avoiding beam conflicts and interference between the terminal device and other terminal devices, and achieving optimal allocation of network resources and solving the problem of beam resource competition.

[0061] In a possible implementation, the method further includes:

[0062] A first configuration instruction is sent to the terminal device, where the first configuration instruction includes the number of candidate beams included in the beam report.

[0084] To facilitate a clear description of the technical solutions of the embodiments of the present application, some of the terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0085] 1. Terminal equipment:

[0086] The terminal devices of the embodiments of the present application may include handheld devices, vehicle-mounted devices, etc. with beam management and transmit beam boosting functions. For example, some terminal devices are: mobile phones, tablet computers, PDAs, laptop computers, mobile internet devices (MIDs), 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 grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, in-vehicle devices, terminal devices in 5G networks or future evolved public land mobile communication networks. Mobile network (PLMN), etc., and the embodiments of the present application are not limited to this.

[0087] As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0088] In addition, in the embodiment of the present application, the terminal device can also be a terminal device in the Internet of Things (IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0089] The terminal device in the embodiments of the present application may also be referred to as: user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, etc.

[0090] 2. Network equipment:

[0091] In the embodiment of the present application, the network device (Network, NW) can be any device with wireless transceiver functions. 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 (e.g., Home evolved Node B, or Home Node B, HNB), Base Band 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. It can also be a gNB in ​​a 5G system, such as NR, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple 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 may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, and implementing radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions. The DU is responsible for processing physical layer protocols and real-time services, and implementing radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. The AAU implements some physical layer processing functions, RF processing, and active antenna-related functions. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can be considered to be sent by the DU, or by both the DU and the AAU. It should be understood that a network device can be a device that includes one or more of a CU node, a DU node, or an AAU node. In addition, the CU may be divided into a network device in an access network (radio access network, RAN), or may be divided into a network device in a core network (core network, CN), which is not limited in this application.

[0093] Network equipment provides services for cells, and terminal devices communicate with the cells through transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network equipment. The cell can belong to a macro base station (for example, macro eNB or macro gNB) or a base station corresponding to a small cell. Small cells here can include: metrocells, microcells, picocells, femtocells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0094] 3. TCI status:

[0095] The Transmission Configuration Indicator (TCI) state is a key technology in 5G NR (New Radio). It instructs the user equipment (UE) on how to receive downlink reference signals (such as CSI-RS and SSB) or the beam configuration information for data transmission. Its core function is to dynamically or semi-statically configure the UE's reception parameters to optimize beam management and transmission efficiency. The TCI state is notified to the UE via RRC signaling (Radio Resource Control) or MAC-CE (Medium Access Control - Control Element), clarifying the Quasi Co-Location (QCL) relationship between the downlink channel / signal and a specific reference signal (such as CSI-RS or SSB). This helps the UE utilize the known reference signal beam characteristics (such as time-frequency offset and spatial parameters) to receive data or control channels, reducing measurement complexity.

[0096] 4. Beam report:

[0097] Beam reporting is the process by which the UE provides optimal beam information to network equipment to support beamforming and beam management. Its core purpose is to help network equipment select the best transmit / receive beam to improve signal quality, reduce interference, and optimize network performance.

[0098] UE-Initiated / Event-Driven (UEI / ED) beam reports are proactively sent by the UE to network devices based on specific events or conditions. They are used to optimize beam management, improve network performance, and reduce air interface signaling overhead.

[0099] 5. Event 7 (Event-7) is the event in which the strongest cell signal on the non-serving frequency band is 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 indication TCI state); Event 2 (Event-2) is the event in which the serving cell signal is lower 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 equipment.

[0100] 6. RSRP (Reference Signal Receiving Power) is a key parameter for measuring wireless signal strength.

[0101] 7. CRI is the CSI-RS (Channel State Information Reference Signal) resource indicator, which is used to identify the optimal CSI-RS beam selected by the UE; SSBRI is the SSB (Synchronization Signal Block, i.e. SS / PBCH Block) resource indicator, which is used to identify the optimal SSB beam selected by the UE.

[0102] 8. Other terms

[0103] In the embodiments of this application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the terms "first chip" and "second chip" are used solely to distinguish between different chips and do not define their order. Those skilled in the art will understand that terms such as "first" and "second" do not define the quantity or execution order, and do not necessarily define differences.

[0104] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0105] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship.

[0109] The following combination Figure 1 The following describes the usage scenarios of the beam report sending method. Figure 1 As shown, the communication system includes a terminal device 110 and a network device 120. The network device 120 can send a beam to the terminal device 110. The terminal device 110 can perform beam management and send a beam report to the network device 120.

[0110] In traditional beam management procedures, the network equipment (NW) can configure / activate frequent periodic or semi-persistent beam reporting (e.g., N best beams and their corresponding L1-RSRPs) or trigger frequent aperiodic beam reporting to promptly obtain the optimal / preferred beam for data / control transmission. However, this obviously results in significant uplink reporting and control signaling overhead. Since the user equipment (UE) is more aware of beam quality changes, the NW may not be able to determine when to trigger aperiodic beam reporting. UE-initiated / event-driven (UEI / ED) beam reporting allows the NW to promptly update the link / beam quality for communications with the UE without consuming excessive resources and power. This is why UEI / ED beam reporting is proposed. This UE-initiated beam reporting process provides more timely beam reports while reducing reporting overhead. Therefore, properly identifying events and efficiently transmitting beam reports are crucial in UEI / ED beam management.

[0111] In a related technology, UEI / ED beam management introduces Event-7, which is used to update the activated Transmission Control Interface (TCI) status. Event-7 is triggered when 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 indicating the TCI status). The UE then initiates an Event-7 beam report, indicating that the new beam has a better TCI status and that the currently activated TCI status needs to be updated. Current discussions have determined that Event-7, unless specifically required, reuses the reporting format of Event-2 whenever possible to reduce complexity. Therefore, the existing Event-7 beam report is established based on the reporting purpose of Event-2, and has shortcomings when applied to Event-7. Therefore, the reporting format of Event-2 is optimized for Event-7. First, the option to report "current beam" in Event-2 is replaced with the RSRP value of the RS corresponding to the Q-th activated TCI state in the Event-7 report. This can be used to indicate which reported beams are the instances that triggered Event-7. Secondly, a 1-bit indication can be directly added to the reporting beam in the Event-7 report to indicate whether the beam triggered the event. On the other hand, the status code point corresponding to the Q-th (Qth) activated TCI state can be reported to clarify the specific index of the "current beam" reported by Event-7.

[0112] In UEI / ED beam management, Event-7 triggering is characterized by the UE initiating an Event-7 beam report once the quality of at least one new beam reaches a threshold (better than the Qth best RS quality derived from the activated TCI state). The network device can update the UE's TCI state based on this beam report. The existing Event-7 beam report format description (from 3GPP RAN1) is shown in Table 1 below:

[0113] Table 1:

[0114]

[0115] The CRI or SSBRI represents the top N beam indexes in the new beam set, where N is configured by RRC parameters. The beam set is configured by the "CSI reporting configuration." Differential L1-RSRP represents the difference from L1-RSRP #1. The "current beam" field in the Event-7 report contains information about beams in activated TCI states and beams in potentially activatable TCI states.

[0116] If RRC enables "current beam", the UE multiplexes "current beam" as the RSRP of the RS corresponding to the Q-th TCI in the beam report of Event-7. The network device can implicitly infer the beam index of the triggering event in the reported beam based on the RSRP, and thus map it to the TCI status of the candidate triggering beam; if the Event-7 beam report reuses the 1-bit indication of the triggering beam event in the Event-2 report, that is, each beam will add a 1-bit indicator bit, the network device can determine the beam index of the triggering event in the reported beam through this indication, and thus map it to the TCI status of the candidate triggering beam.

[0117] However, the above solution has problems when it comes to updating the activated TCI status: the beam reporting format of Event-2 is reused, and the UE reports the beams in the new beam set. This set is relatively independent of the beams corresponding to the activated TCI status. The report can only determine which beams correspond to the TCI status that can be activated. At the same time, the consensus report structure does not indicate the validity of the activated TCI status. That is, the network equipment cannot determine the difference in the validity of the activated TCI status through the report, and cannot perform scheduling based on the difference in TCI status.

[0118] In view of this, an embodiment of the present application provides a method for sending a beam report and proposes the following solution: adding quality sorting information of the TCI code points to the Event-7 beam report, reporting the activated TCI status and its sorting with poor quality, so that the network device can clearly trigger the Event-7 beam after receiving the Event-7 beam report, and at the same time perform TCI scheduling updates according to the activated TCI quality sorting.

[0119] The method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0120] It should be understood that the following description is merely for ease of understanding and explanation, using the interaction between a terminal device and a network device as an example to describe the methods provided in the embodiments of this application in detail. However, this description does not constitute any limitation on the execution of the methods provided in this application. For example, the terminal devices shown in the embodiments below can be replaced with components (such as chips or circuits) configured in the terminal devices. The network devices shown in the embodiments below can also be replaced with components (such as chips or circuits) configured in the network devices.

[0121] The embodiments shown below do not particularly limit the specific structure of the execution subject of the method provided in the embodiments of the present application. As long as it is possible to communicate according to the method provided in the embodiments of the present application by running a program that records the code of the method provided in the embodiments of the present application, for example, the execution subject of the method provided in the embodiments of the present application can be a terminal device, or a functional module in the terminal device that can call and execute the program.

[0122] Figure 2 This is a schematic flow chart of a method for sending a beam report provided by an embodiment of the present application from the perspective of device interaction. Figure 2 As shown, the method for sending the beam report may include:

[0123] S201. The terminal device detects the quality index of each candidate beam in the candidate beam set and compares it with the quality index of the target beam, where the target beam is the beam corresponding to the activated TCI state with the Qth-ranked quality index in the activated transmission configuration indication TCI state set.

[0124] In an embodiment of the present application, the terminal device detects the quality index of each candidate beam in the candidate beam set (i.e., the new beam set), and compares it with the quality index 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 index of at least one candidate beam in the candidate beam set exceeds the quality index of the target beam, it determines the number information of the candidate beams that exceed the quality index of the target beam, and the sorting information of the corresponding beams of the activated TCI state set according to the quality index.

[0126] In an embodiment of the present application, if it is detected that 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, and the number information of the candidate beams that exceed the quality index of the target beam can be determined, that is, the number information of the candidate beams that trigger Event-7, and it is also necessary to determine the sorting information of the beams corresponding to the activated TCI state set according to the quality index.

[0127] S203. The terminal device generates a beam report; wherein the beam report includes the identification and quality index of each candidate beam in the candidate beam set, the quantity information, and the sorting information.

[0128] In an embodiment of the present application, when a terminal device generates an Event-7 beam report, the beam report may include the identifier and quality index of each candidate beam (similar to the Event-7 beam report in the prior art). It may also include information about the number of candidate beams that exceed the quality index of the target beam, and information about the sorting of beams corresponding to the activated TCI state set according to the quality index. As an example, the beam report format of an embodiment of the present application is described in Table 2 below:

[0129] Table 2:

[0130]

[0131] Among them, CRI or SSBRI #1~ CRI or SSBRI #N are the identifiers of each candidate beam, and L1-RSRP #1 and Differential L1-RSRP #2~ Differential L1-RSRP #N can represent the quality indicators of each candidate beam; the number information of beams corresponding to more than Q-th activated TCI is the number information of beams corresponding to more than Q-th activated TCI in CRI or SSBRI #1~ CRI or SSBRI #N; the sorting information of beams corresponding to the activated TCI state set according to the quality indicator can be the sorting information of all beams or part of the beams corresponding to the activated TCI state set according to the quality indicator, among which, if it is the sorting information of part of the beams corresponding to the activated TCI state set according to the quality indicator, it can specifically be the sorting information of part of the beams with the worst quality according to the quality indicator.

[0132] It should be noted that the information on the number of candidate beams that exceed the quality index of the target beam, and the sorting information of the beams corresponding to the activated TCI state set according to the quality index can be encoded in any feasible way, and the encoded information can be added to the beam report of Event-7.

[0133] S204. The terminal device sends the beam report to the network device.

[0134] In an embodiment of the present application, after generating a beam report of Event-7, the terminal device sends the beam report to the network device.

[0135] Furthermore, the network device can determine the candidate beams that exceed the quality index of the target beam (the candidate beams that trigger Event-7) based on the identifiers and quality indicators of each candidate beam in the candidate beam set included in the beam report, and the number information of candidate beams that exceed the quality index of the target beam, wherein the identifiers and quality indicators of each candidate beam can be sorted according to the quality indicators, and the candidate beams corresponding to the number information with the highest quality indicators in the sorting are determined as the candidate beams that exceed the quality index of the target beam (the candidate beams that trigger Event-7); in addition, the network device can determine one or more beams with poor quality in the activated TCI state set as beams to be replaced based on the sorting information of the corresponding beams in the activated TCI state set according to the quality indicators, and can make more accurate TCI activation and scheduling updates based on the candidate beams that exceed the quality indicators of the target beams and the beams to be replaced in the activated TCI state set.

[0136] In some embodiments, the network device may send a TCI state set update instruction generated based on the beam report to the terminal device, wherein the TCI state set update instruction includes an updated activated TCI state set determined by the network device based on the beam report; the terminal device may use the updated activated TCI state set to replace the activated TCI state set to implement the update of the TCI state set, and then may perform beam management based on the updated activated TCI state set, such as switching beams and other operations.

[0137] Specifically, after receiving the TCI state set update instruction, the terminal device can overwrite the activated TCI state set with the updated activated TCI state set, and can determine the target candidate beam of the TCI state to be activated, and the beam to be replaced in the activated TCI state set, activate the TCI state of the target candidate beam of the TCI state to be activated, and deactivate the TCI state of the beam to be replaced in the activated TCI state set, thereby realizing the update of the activated TCI state set.

[0138] The method for sending a beam report provided in an embodiment of the present application detects the quality index of each candidate beam in a candidate beam set through a terminal device, and compares it with the quality index of a target beam, wherein the target beam is the beam corresponding to the activated TCI state whose quality index ranks Q in the activated transmission configuration indication TCI state set; if it is detected that the quality index of at least one candidate beam in the candidate beam set exceeds the quality index of the target beam, the number information of the candidate beams exceeding the quality index of the target beam and the sorting information of the beams corresponding to the activated TCI state set according to the quality index are determined; a beam report is generated; wherein the beam report includes the identification and quality index of each candidate beam in the candidate beam set, the quantity information and the sorting information; and the beam report is sent to a network device. In an embodiment of the present application, the terminal device adds information on the number of candidate beams that exceed the quality index of the target beam and the sorting information of the corresponding beams of the activated TCI state set according to the quality index in the beam report, so that the network device can clearly trigger the candidate beams of Event-7 and the beams to be replaced in the activated TCI state set, and thus can update the TCI status more accurately, ensuring that the subsequent activated TCI status has higher reliability.

[0139] In some embodiments, when the terminal device determines the number of candidate beams that exceed the quality indicator of the target beam in S202, the following may be specifically included:

[0140] Determining, according to the number of candidate beams included in the beam report, a target bit length of the number information;

[0141] The number of candidate beams exceeding the quality indicator of the target beam is converted into a code of the target bit length as the quantity information.

[0142] In an embodiment of the present application, the number of candidate beams included in the beam report is N. For example, the beam report format shown in Table 2 includes CRI or SSBRI #1 to CRI or SSBRI #N, totaling N candidate beams. The number N of candidate beams included in the beam report can be configured by a network device. For example, the network device sends a first configuration instruction to a terminal device, where the first configuration instruction includes the number of candidate beams included in the beam report, thereby enabling the network device to configure the number N of candidate beams included in the beam report. The first configuration instruction can be an RRC instruction or any other feasible instruction. Of course, configuration can also be performed through any other feasible means.

[0143] The terminal device can determine the target bit length of the quantity information of candidate beams used to represent the quality index of the target beam (the beam corresponding to the Q-th activated TCI state in the activated TCI state set) based on the number 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 required, meaning the candidate beams included in the beam report are the beams that trigger Event-7, and the quantity information does not need to be added to the beam report. When N=2, 1 bit can be used to represent the quantity information, with 0 representing 1 and 1 representing 2. When N=3-4, 2 bits can be used to represent the quantity information, with "00" representing 1, "01" representing 2, and so on, accumulating to "11" to represent 4. When N=5-8, 3 bits can be used, with "000" representing 1, and so on, accumulating to "111" to represent 8. This solution only requires the target bit length. Based on the encoding of the quantity information of the target bit length, the network device can determine the candidate beam that exceeds the quality indicator of the target beam, i.e., the candidate beam that triggers Event-7, based on the beam report including the identifier and quality indicator of each candidate beam in the candidate beam set. This reduces the amount of data compared to the prior art method of adding a 1-bit indicator bit to each beam.

[0145] In some embodiments, when the terminal device determines the sorting information of the beams corresponding to the activated TCI state set according to the quality indicator in S202, it may specifically include:

[0146] Encode the index number of the beam corresponding to the activated TCI state set;

[0147] According to the order of the quality indicators of the beams corresponding to the activated TCI state set, the codes of the beams corresponding to the activated TCI state set are sorted to obtain the sorting information.

[0148] In an embodiment of the present application, the sorting information of the beams corresponding to the activated TCI state set according to the quality index can be directly sorted by the size of the quality index. However, considering that the beam index may be long, resulting in a large amount of data for the sorting information of the beams corresponding to the activated TCI state set according to the quality index, in an embodiment of the present application, the sorting information of the beams corresponding to the activated TCI state set according to the quality index can be encoded to reduce the amount of data. Specifically, the index number of the beam corresponding to the activated TCI state set can be encoded, and its encoding rule is known to the terminal device and the network device, that is, the terminal device can encode the index number of the beam according to the encoding rule, and the network device can also decode the index number of the beam based on the encoding rule after obtaining the encoding of the index number of the beam. In this way, the beam report only needs to add the sorting information sorted by the encoding of the index number of the beam corresponding to the activated TCI state set, and the network device can obtain the sorting information of the beam corresponding to the activated TCI state set according to the quality index. The encoding rule can adopt any feasible method as long as it can reduce the amount of data of the sorting information.

[0149] In an optional manner, a binary encoding method of a specific length may be used, wherein the length of the binary encoding may 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 method may be used, with 000~111 representing the 8 beams corresponding to the activated TCI state set. The index numbers of the 8 beams corresponding to the activated TCI state set may be mapped to 000~111. The mapping method may 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, Figure 3 As shown, the network device can configure the TCI state index number from 0 to 127, and the activated TCI state set corresponds to the index numbers of 8 beams from 9 to 16. The smallest index number 9 can be mapped to 000, the index number 10 is mapped to 001, and so on until the index number 16 is mapped to 111. Of course, the index numbers of the activated TCI state set corresponding to the 8 beams may not necessarily be continuous, but they can still be mapped from small to large. The network device knows the index number of the beam corresponding to the activated TCI state set, and also follows the mapping method from small to large for the index number, and can map from binary code back to the index number.

[0150] Furthermore, the terminal device can sort the codes of the beams corresponding to the activated TCI state set by the size of the quality index as sorting information. For example, in a measurement, it is determined that the index numbers of the beams corresponding to the activated TCI state with poor quality that need to be reported are sorted as 16 > 14 > 15, where index number 14 corresponds to "101", index number 15 corresponds to "110", and index number 16 corresponds to "111". Therefore, the sorting information is (111 101 110). This sorting information (111 101 110) can be added to the beam report. The network device can decode this sorting information to determine that the index numbers of the beams corresponding to the activated TCI states are sorted as 16 > 14 > 15.

[0151] It should be noted that the above-mentioned mapping method may also adopt other mapping methods, such as mapping the index number from large to small to binary code, or adopting other feasible mapping methods, which are not limited in the embodiments of the present application.

[0152] In some embodiments, the ranking information of beams corresponding to the activated TCI state set according to the quality indicator may be ranking information of all or some of the beams corresponding to the activated TCI state set according to the quality indicator. Specifically, if the ranking information of some of the beams corresponding to the activated TCI state set according to the quality indicator is ranking information of some of the beams with the worst quality according to the quality indicator, several different methods are provided below:

[0153] Method 1: sort the codes of all beams corresponding to the activated TCI states in the activated TCI state set 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 method one, the sorting information of all beams corresponding to the activated TCI state set is added to the beam report. When the index number of the beam corresponding to the activated TCI state is encoded, the encoded sorting of all beams corresponding to the activated TCI state in the activated TCI state set can be added to the beam report. In this way, the network device can know the quality status of all beams corresponding to the activated TCI state set, which is convenient for subsequent scheduling.

[0155] Method 2: According to the order of the quality indicators of the beams corresponding to the activated TCI state set, the codes of the beams corresponding to a preset number of activated TCI states with the worst quality indicators in the activated TCI state set are sorted to obtain the sorting information.

[0156] In the second method, a preset number L can be pre-configured, where L is a fixed number. In the beam report, only the sorting information of the L beams with the worst quality indicators in the corresponding beams in the activated TCI state set is reported, that is, the sorting information of the last L beams with the quality indicators. When the index numbers of the beams corresponding to the activated TCI states are encoded, the encodings 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 specific instructions, and the latter can be configured through other methods. It 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 method, there is no need to report all the sorting information of all beams corresponding to the activated TCI state set, which can reduce the data volume of the sorting information.

[0157] Method three: sort the codes corresponding to the beams whose quality indicators in the activated TCI state set are ranked after R in the activated TCI state set according to the order of the quality indicators of the beams corresponding to the activated TCI state set to obtain the sorting information.

[0158] In method three, similar to method two, it is also necessary to pre-configure a parameter, that is, a preset ranking R. In the beam report, only the sorting information of the beams whose quality indicators rank after R in the corresponding beams in the activated TCI state set is reported. When the index number of the beam corresponding to the activated TCI state is encoded, the encoding of the beams corresponding to the activated TCI state whose quality indicators rank after R 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 specific instructions, and the latter can be configured through other methods. It is not limited in the embodiment of the present application, and R also needs to be less than the number of beams corresponding to the activated TCI state set. Optionally, the preset ranking R can reuse Q, that is, R can be equal to Q. Through method three, there is no need to report all the sorting information of all beams corresponding to the activated TCI state set, which can reduce the data volume of the sorting information.

[0159] Method 4: Determine the target number of beams included in the sorting information based on the number of candidate beams whose quality indicators exceed the target beam; sort the codes of the beams corresponding to the target number of activated TCI states with the worst quality indicators in the activated TCI state set according to the order of the quality indicators of the beams corresponding to the activated TCI state set to obtain the sorting information.

[0160] In method four, a dynamic number can be used to determine the target number K of beams included in the sorting information based on the number of candidate beams whose quality indicators exceed the target beam. Then, only 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 lowest quality indicators. When the index numbers of the beams corresponding to the activated TCI states are encoded, the codes of the K 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, which has high flexibility and practicality.

[0161] Optionally, the number of candidate beams that exceed the quality index 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 that exceed the quality index of the target beam. In this way, under relatively ideal conditions, 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 that exceed the quality index of the target beam, so as to achieve accurate update of the TCI state.

[0162] Optionally, when determining the target number of beams included in the sorting information based on the number of candidate beams that exceed the quality index of the target beam, if the number of candidate beams that exceed the quality index of the target beam is greater than or equal to MQ, the target number is determined to be MQ, 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 that exceed the quality index of the target beam is less than MQ, the number of candidate beams that exceed the quality index of the target beam is determined to be the target number.

[0163] In this embodiment, if the number of candidate beams exceeding the quality index of a target beam (the beam corresponding to the Qth activated TCI state with the highest quality index) is greater than or equal to MQ, then the number of candidate beams exceeding the quality index of the target beam exceeds the number of beams with the Qth or higher quality index in the activated TCI state set. This means that even if all beams with the Qth or higher quality index in the activated TCI state set are replaced, candidate beams exceeding the quality index of the target beam may still remain. Therefore, only the ranking information of the beams with the Qth or higher quality index in the activated TCI state set needs to be reported, i.e., the target number equals MQ. If the number of candidate beams exceeding the quality index of the target beam is less than MQ, the target number may be set as the number of candidate beams exceeding the quality index of the target beam. This means that the target number of beams included in the ranking information is equal to the number of candidate beams exceeding the quality index of the target beam. Ideally, the network device can replace the K beams with the worst quality indexes in the activated TCI state set with the candidate beams exceeding the quality index of the target beam, thereby accurately updating the TCI state.

[0164] Of course, the number of beams included in the sorting information is not limited to being determined by the various methods mentioned above, and any other feasible method may also be used, which is not limited in the embodiments of the present application.

[0165] Figure 4 This is a schematic flow chart of a beam switching method based on beam reporting provided by an embodiment of the present application from the perspective of device interaction. Figure 4 As shown, in Figure 2 On the basis, after the terminal device sends the beam report to the network device, the beam switching method based on the beam report may include:

[0166] S301. A network device receives a beam report sent by a terminal device, where the beam report includes: an identifier and quality indicator of each candidate beam in a candidate beam set, information about the number of candidate beams that exceed the quality indicator of a target beam, and ranking information of beams corresponding to an activated TCI state set according to the quality indicator, where the target beam is the beam corresponding to the activated TCI state with the Qth highest quality indicator in the activated transmission configuration indication TCI state set.

[0167] S302. The network device determines, based on the beam report, candidate beams that exceed the quality index of the target beam and beams to be replaced in the activated TCI state set.

[0168] In an embodiment of the present application, the network device can determine the candidate beam that exceeds the quality index of the target beam (the candidate beam that triggers Event-7) based on the identifier and quality index of each candidate beam in the candidate beam set included in the beam report, and the number information of the candidate beams that exceed the quality index of the target beam, wherein the identifier and quality index of each candidate beam can be sorted according to the quality index, and the candidate beams corresponding to the number information with the highest quality index in the sorting are determined as the candidate beam that exceeds the quality index of the target beam (the candidate beam that triggers Event-7); in addition, the network device can determine one or more beams with poor quality in the activated TCI state set as beams to be replaced based on the sorting information of the corresponding beams according to the quality index of the activated TCI state set, and can determine the candidate beams with quality indicators exceeding the target beam and the beams to be replaced in the activated TCI state set.

[0169] Furthermore, the network device may perform TCI activation and scheduling updates based on the candidate beams that exceed the quality index of the target beam and the beams to be replaced in the activated TCI state set.

[0170] In some embodiments, the network device may perform the following process:

[0171] S303: The network device determines an updated activated TCI state set according to the candidate beams that exceed the quality indicator of the target beam and the beams to be replaced in the activated TCI state set.

[0172] In an embodiment of the present application, the network device may replace at least one beam to be replaced in the activated TCI state set with at least one candidate beam among the candidate beams that exceeds the quality index of the target beam, thereby determining an updated activated TCI state set.

[0173] Optionally, when the network device replaces the beam to be replaced in the activated TCI state set with a candidate beam that exceeds the quality index of the target beam, the replacement rule can be any feasible rule, such as replacing the beam to be replaced with the worst quality with the candidate beam with the best quality among the candidate beams that exceed the quality index of the target beam, replacing the beam to be replaced with the second worst quality with the candidate beam with the second best quality, and so on. Of course, other replacement rules can also be used, which are not limited in the embodiments of the present application.

[0174] The specific replacement process may be that the network device uses the TCI state of the candidate beam that exceeds the quality index of the target beam to replace the TCI state of the beam to be replaced in the activated TCI state set, 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 an updated activated TCI state set.

[0176] In an embodiment of the present application, the network device can send the updated activated TCI state set to the terminal device, and can send it through any feasible instruction, which is recorded as a TCI state set update instruction.
