Abstract
Description
Technical Field
[0001] This disclosure relates to the field of wireless communication technology, and in particular to a beam measurement method, apparatus, electronic device, and computer program product. Background Technology
[0002] A typical use case for AI beam management is AI spatial beam prediction (such as...). Figure 2 This means that, based on an AI model and the Layer 1-Reference Signal Received Power (L1-RSRP) of a small number of beam pairs, the L1-RSRP of all beam pairs can be predicted and the top K beams with the best RSRP can be reported for subsequent determination of the optimal beam.
[0003] However, some of the Top K beams reported above may be unmeasured beams (i.e., the quasi-co-located QCL parameters are unknown) and cannot be used for beam indication and / or data transmission.
[0004] There are two existing methods to solve the above problems:
[0005] Method 1: Base station 102 periodically measures the Top K beams reported by UE101 and converts the unknown TCI (unknown TCI) into a known TCI (known TCI). This method ensures that base station 102 knows the QCL parameters of all Top K beams before performing beam indication.
[0006] Method 2: Base station 102 directly activates the TCI corresponding to the Top K beam reported by UE101, including unknown TCIs. During the activation process, aperiodic Top K beam measurement is triggered to convert unknown TCIs into known TCIs before beam indication is performed.
[0007] In the existing aperiodic CSI reporting framework, DCI triggers a trigger state, and each trigger state can trigger up to 16 report configurations. Each report configuration is associated with an aperiodic resource set, and the DCI simultaneously triggers the transmission of the aperiodic resource set.
[0008] However, the Top K beam may change after each prediction, requiring network devices to frequently reconfigure RRC parameters to update the Top K beam resource set. This frequent parameter update leads to significant signaling overhead and latency. Summary of the Invention

[0049] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.
[0050] First, refer to Figure 1 Overview of application scenarios according to embodiments of this disclosure.
[0051] Figure 1 This illustration is a schematic diagram of an application scenario of the beam measurement method according to an embodiment of this disclosure. The technical solutions of this disclosure can be applied to various wireless communication systems, such as: Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), Advanced Long Term Evolution (LTE-A), New Radio (NR), evolution systems of NR, LTE on Unlicensed Spectrum (LTE-U), NR on Unlicensed Spectrum (NR-U), Non-Terrestrial Network (NTN) systems, Universal Mobile Telecommunications System (UMTS), Wireless Local Area Network (WLAN), Wireless Fidelity (WiFi), 5G, or other communication systems. It is readily understood that the communication system architecture and service scenarios described in this disclosure are for the purpose of more clearly illustrating the technical solutions of this disclosure and do not constitute a limitation on the technical solutions provided by this disclosure. Those skilled in the art will understand that with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided by this disclosure are also applicable to similar technical problems.
[0052] like Figure 1 As shown, the application scenarios include at least: terminal devices (e.g., UE101) and network devices (e.g., base station 102).
[0053] The terminal equipment can be a user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, smart terminal, wireless communication equipment, user agent, or user device. The terminal can also be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, relay device, vehicle-mounted device, wearable device, terminal in next-generation communication systems such as NR networks, or terminal in future evolved public land mobile networks (PLMNs), etc., without specific limitations.
[0054] Network equipment can be a device used for communication with terminal devices. Specifically, network equipment can be a base station (BTS) in a GSM or CDMA communication system, a base station (NodeB, NB) in a WCDMA communication system, an evolved Node B (eNB or eNodeB) in an LTE communication system, a next-generation evolved Node B (ng-eNB) in an NR communication system, or a next-generation Node B (gNB) in an NR communication system.
[0055] In addition, network devices can also be access points (APs) or relay stations in wireless local area networks (WLANs), network devices in future PLMN networks, or network devices in NTN networks. It should be noted that in some network deployments, a network device can be a standalone node to implement all the functions of the aforementioned base station; it can include centralized units (CUs) and distributed units (DUs), such as gNB-CUs and gNB-DUs, and can also include active antenna units (AAUs). The CU can implement some of the functions of the network device, and the DU can implement some of the functions of the network device. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of the Radio Resource Control (RRC) layer, Service Data Adaptation (SDAP) layer, and Packet Data Convergence (PDCP) layer. The DU is responsible for handling physical layer protocols and real-time services, implementing the functions of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and Physical (PHY) layer. Furthermore, the AAU implements some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since information from the RRC layer ultimately becomes, or is derived from, information from the PHY layer, in this network deployment, higher-layer signaling (RRC) can be assumed to be sent by the DU, or by both the DU and AAU. It is understood that network devices can include at least one of the CU, DU, and AAU.
[0056] To facilitate understanding of the embodiments of this disclosure, the following is a brief introduction to several terms involved in this disclosure.
[0057] 1. Beam: A beam is a wireless signal whose energy is concentrated within a small area, creating an effect similar to a light beam. High-frequency signals are transmitted through beams, increasing the transmission distance. Beams are produced using beamforming technology, which includes digital beamforming, analog beamforming, and hybrid digital / analog beamforming. Beams generated by digital beamforming are called digital beams, while those generated by analog beamforming are called analog beams.
[0058] The beam used to transmit signals is called the transmit beam, and the beam used to receive signals is called the receive beam. The transmit beam refers to the distribution of signal strength in different directions in space after the signal is transmitted through the antenna, while the receive beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna. There is a beam-pairing relationship between the transmit and receive beams.
[0059] The beam that a network device assigns to a terminal device for data transmission can be called the serving beam. Other beams that are assigned along with the serving beam can be called interference beams, which can interfere with the data on the serving beam.
[0060] 2. Channel State Information Acquisition (CSI): Measure the channel quality of the serving beam, including acquiring the channel-quality indicator (CQI), rank indicator (RI), precoding-matrix indicator (PMI), signal-to-interference plus noise ratio (SINR), etc.
[0061] 3. Interference measurement: Measure information about interfering beams, including strong interfering beam identifiers (IDs), weak interfering beam IDs, and multi-user channel-quality indicators (MU-CQI) of the serving beam under interference from interfering beams.
[0062] 4. Time Domain Attributes: Different time domain attributes can be used to indicate different time domain behaviors in interference measurement resource configuration and interference measurement reporting configuration. Specifically, the time domain attributes of interference resource configuration can be used to indicate the time domain behavior of the terminal device in receiving interference signals; the time domain attributes of measurement reporting configuration can be used to indicate the time domain behavior of the terminal device in reporting interference measurement results.
[0063] As an example rather than a limitation, time-domain properties may include periodicity, semi-persistentity, and aperiodicity.
[0064] It should be understood that the beamforming examples in the NR protocols listed above are merely illustrative and should not be construed as limiting this application. This application does not preclude the possibility of defining other terms in future protocols to represent the same or similar meanings.
[0065] 5. Quasi-co-location (QCL): Also known as quasi-co-location. Antenna ports with a QCL relationship have the same reference signals with identical parameters, or the parameters of one antenna port can be used to determine the parameters of another antenna port with a QCL relationship, or the two antenna ports have the same parameters, or the parameter difference between the two antenna ports is less than a certain threshold. The parameters may include one or more of the following: delay spread, Doppler spread, Doppler shift, average delay, average gain, and spatial Rx parameters. Spatial Rx parameters may include one or more of the following: angle of arrival (AOA), average AOA, AOA spread, angle of departure (AOD), average departure angle AOD, AOD spread, receive antenna spatial correlation parameters, transmit antenna spatial correlation parameters, transmit beam, receive beam, and resource identifier.
[0066] 6. Transmission Configuration Indicator (TCI) State: This state indicates the QCL relationship between two reference signals. Each TCI state may include the Serve Cell Index, the Bandwidth Part (BWP) Identifier (ID), and the Reference Signal Resource Identifier. The Reference Signal Resource Identifier may be, for example, at least one of the following: Non-zero power (NZP) CSI-RS Reference Signal Resource Id, Non-zero power CSI-RS Reference Signal Resource Set Id, or SSB Index.
[0067] Optionally, the network device can also assign QCL identifiers to beams that have quasi-colocation (QCL) relationships within the frequency resource group associated with the beams.
[0068] QCL (Quick Channel Context) relationships are used to indicate that multiple resources share one or more identical or similar communication characteristics. For multiple resources with a QCL relationship, identical or similar communication configurations can be used. For example, if two antenna ports have a QCL relationship, the large-scale channel characteristics of one port transmitting one symbol can be inferred from the large-scale channel characteristics of the other port transmitting one symbol. Large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, receive parameters, terminal equipment receive beam number, transmit / receive channel correlation, receive angle of arrival, spatial correlation of receiver antennas, angel-of-arrival (AoA), average angle of arrival, and spread of the angel-of-arrival, etc.
[0069] QCL also includes spatial quasi-co-location (Spatial QCL). Spatial QCL can be considered a type of QCL. Spatial quasi-co-location can be understood from both the transmitting and receiving perspectives. From the transmitting end's perspective, if two antenna ports are spatially quasi-co-location, it means that the corresponding beam directions of these two antenna ports are spatially consistent. From the receiving end's perspective, if two antenna ports are spatially quasi-co-location, it means that the receiver can receive the signals transmitted by both antenna ports in the same beam direction.
[0070] The serving cell index, BWPID, and reference signal resource identifier refer to the reference signal resources used during beam training, along with their corresponding serving cells and BWPs. During beam training, network devices transmit reference signals using different transmit beams based on different reference signal resources; therefore, reference signals transmitted via different transmit beams can be associated with different reference signal resources. Similarly, terminal devices receive reference signals using different receive beams based on different reference signal resources; thus, reference signals received via different receive beams can also be associated with different reference signal resources. Therefore, during beam training, terminal devices can maintain the correspondence between the serving cell index, BWPID, and reference signal resource identifier and the receive beams, and network devices can maintain the correspondence between the serving cell index, BWPID, and reference signal resource identifier and the transmit beams. The reference signal resource identifier allows for the establishment of a pairing relationship between receive and transmit beams.
[0071] During subsequent communication, the terminal device can determine the receiving beam based on the TCI state, including spatial quasi-synchronous (QCL), indicated by the network device.
[0072] Furthermore, TCI status can be configured globally. If the TCI status index is the same in TCI status configurations for different cells and different BWPs, then the corresponding TCI status configurations will also be the same.
[0073] Figure 2 This is a schematic diagram illustrating the principle of AI spatial beam prediction according to an embodiment of this disclosure. As described above, a typical use case for AI beam management is AI spatial beam prediction. Figure 2 As shown, in AI spatial beam prediction, set A represents all beam pairs, and set B represents a subset of beam pairs in set A. The prediction principle is to input the measured Layer 1-Reference Signal Received Power (L1-RSRP) of set B into the trained AI model. The AI model then makes predictions to obtain the L1-RSRP of set A and selects the optimal beam for communication transmission.
[0074] Specifically, assuming base station 102 has 64 transmit beams, and base station 102 is configured with 8 Channel State Information-Reference Signals (CSI-RS) (set B), with a reference signal period of 80ms, UE101 measures the L1-RSRP of the 8 beams at each moment. UE101 uses the measured 8 L1-RSRPs as input to the AI model, and predicts the L1-RSRPs of the 64 beams based on the AI model. UE101 reports the Resource Indicators (CRIs) and L1-RSRPs of the K (K≥1) beams with the best RSRPs (i.e., top K) in set A. Based on the RSRP values of the top K beams and beam load, base station 102 instructs one of these beams (i.e., the optimal beam mentioned above) to communicate with UE101.
[0075] However, some of the Top K beams reported by UE101 may be unmeasured beams, i.e., the QCL parameters are unknown; while the beams used by base station 102 for beam indication and / or data transmission should be beams with known QCL parameters.
[0076] Currently, there are two existing technologies that address the above problems:
[0077] Method 1: Base station 102 periodically measures the Top K beams reported by UE101 and converts the unknown TCI (unknown TCI) into a known TCI (known TCI). This method ensures that base station 102 knows the QCL parameters of all Top K beams before performing beam indication.
[0078] Method 2: Base station 102 directly activates the TCI corresponding to the Top K beam reported by UE101, including unknown TCIs. During the activation process, aperiodic Top K beam measurement is triggered to convert unknown TCIs into known TCIs before beam indication is performed.
[0079] In the existing aperiodic CSI reporting framework, DCI triggers a trigger state, and each trigger state can trigger up to 16 reportconfigs. Each reportconfig is associated with an aperiodic resource set, and the DCI simultaneously triggers the transmission of the aperiodic resource set. After each UE101 prediction, the Top K beam may change, which requires base station 102 to frequently reconfigure RRC parameters to update the Top K beam resource set. This frequent parameter update leads to significant signaling overhead and latency.
[0080] Figure 3 This is a flowchart illustrating a beam measurement method according to an embodiment of the present disclosure. Figure 3 As shown, the beam measurement method applied to terminal equipment may include at least the following steps.
[0081] In step S301, a first message and / or a second message and / or a third message sent by a network device are received. The first message and / or the second message and / or the third message are used to instruct the terminal device to measure and / or report at least one reference signal. The first message includes at least one of the following: reference signal resource set configuration and first channel state information (CSI) reporting configuration. The second message includes at least one of the following: transmission configuration indication status activation information, reference signal index indication information, association information between the first trigger status and CSI reporting configuration, and association information between the first trigger status and the reference signal resource set. The third message includes at least one of the following: CSI request information and transmission configuration indication status.
[0082] The first message is carried in Radio Resource Control (RRC) signaling; the second message is carried in Media Access Control (MACCE) control element; and the third message is carried in Downlink Control Information (DCI). See [link to details] for further information. Figure 5 The examples and embodiments one through four are described in further detail.
[0083] Figure 4 This is a further illustration of a method flowchart for beam measurement according to an embodiment of the present disclosure. For example... Figure 4 As shown, a beam measurement method applied to network devices may include at least the following steps.
[0084] In step S401, a first message and / or a second message and / or a third message are sent to the terminal device. The first message and / or the second message and / or the third message instruct the terminal device to measure and / or report at least one reference signal. The first message includes at least one of the following: reference signal resource set configuration and first channel state information (CSI) reporting configuration. The second message includes at least one of the following: transmission configuration indication state activation information, reference signal index indication information, association information between the first trigger state and the CSI reporting configuration, and association information between the first trigger state and the reference signal resource set. The third message includes at least one of the following: CSI request information and transmission configuration indication state. This step is the opposite of step S301; similarly, see [link to relevant documentation] for details. Figure 5 The examples and embodiments one through four are described in further detail.
[0085] Figure 5 This is a flowchart illustrating the overall process of a beam measurement method according to Embodiment 1 of this disclosure. Figure 5 As shown, the beam measurement method of Embodiment 1 of this disclosure includes at least the following execution entities: UE101 and base station 102, and the method may include at least the following steps.
[0086] Example 1:
[0087] 5.1 Base station 102 sends a first message to UE 101, where the first message may be RRC signaling. RRC is a set of protocols used in wireless communication for establishing, configuring, maintaining, and releasing wireless connections. It is responsible for the allocation and management of wireless resources, including power control, connection settings, measurement reports, etc.
[0088] Specifically, base station 102 can configure a reference signal resource set through RRC signaling. The reference signal resource set can be an aperiodic resource set, including at least one of the following: reference signal resource set index, reference signal index, and second time offset value.
[0089] 5.2 Base station 102 sends a second message to UE 101, wherein the second message may be MACCE. MACCE may be used to instruct UE 101 to measure and / or report at least one reference signal.
[0090] Among them, MACCE is a control element of the MAC layer, used to transmit specific control information in wireless communication, such as synchronization information, scheduling requests, power control commands, etc.
[0091] Specifically, base station 102 can activate multiple TCI states by sending MACCE, and simultaneously trigger the transmission of corresponding reference signals for a subset of the multiple TCI states in the reference signal resource set. The MACCE may include: transmission configuration indication state activation information (i.e., TCI state activation information); the TCI state activation information may further include at least one of the following: TCI state index, and a first time offset value.
[0092] In other words, the aforementioned reference signal resource set can be understood as a complete set including all reference signals. The multiple TCI states include the Top K beams in the reference signal resource set (which can be understood as a subset of the complete set). As mentioned above, the QCL parameters of some beams in the Top K beams predicted by the AI model are unknown, so the subset of these multiple TCI states includes unknown TCIs in the Top K beams.
[0093] The time offset between the reference signal and the time slot where the first message is located or the HARQ feedback of the first message is equal to the first time offset of the first resource set plus the second time offset.
[0094] Furthermore, the aforementioned first time offset value can further save network overhead. When multiple UE101s need to report, the reporting time of multiple UE101s can be aligned by the first time offset value, that is, multiple UE101s can send in the same time slot, thereby saving network overhead.
[0095] 5.3 UE101 determines and measures. As described above, UE101 determines at least one reference signal based on the first message and the second message, and measures it, which can be understood as measuring the Top K beam of the unknown TCI.
[0096] 5.4 UE101 sends a fourth message to base station 102. This fourth message may include: MACCE, Physical Uplink Control Channel (PUCCH), or Physical Uplink Shared Channel (PUSCH). As described above, the fourth message includes the measurement results obtained in step 5.3, wherein the measurement results include at least one of the following: an acknowledgment signal (e.g., ACK / NACK, where ACK can be used to indicate completion of the measurement); Layer 1 Reference Signal Received Power (L1-RSRP); and Layer 1 Signal-to-Interference-Noise Ratio (L1-SINR).
[0097] 5.5 Base station 102 determines the optimal beam. That is, based on information such as different beam loads, L1-RSRP, and L1-SINR, base station 102 determines the optimal beam and instructs UE 101 to use a certain beam in Top K for communication.
[0098] In one example embodiment, the RRC signaling (i.e. the first message) configured by base station 102 includes an aperiodic resource set 1 (e.g., a total of 64 reference signals, with reference signal index RS IDs of 1 to 64, denoted as RS ID = 1 to 64), a second time offset value of 4 time slots, and the TCI state IDs of the TCI states corresponding to RS IDs of 1 to 64 are also 1 to 64, denoted as TCI state ID = 1 to 64.
[0099] Base station 102 sends set B (with RS ID = 70~77). UE101 uses the L1-RSRP of set B as the input of the AI model and predicts the reference signal indices of the Top 5 beams as RS ID = 1, 2, 3, 4, 5, where RS ID 1 and 2 are unknown TCIs.
[0100] Base station 102 sends MACCE (i.e., the second message) to UE101 in time slot n to activate TCI state IDs corresponding to RS IDs 1 to 5, and at the same time triggers the aperiodic transmission of RS1 and RS2 corresponding to unknown TCI state IDs 1 and 2, so that RS1 and RS2 are transmitted in time slot n+4. Meanwhile, the first time offset value in MACCE is indicated as time slot 2.
[0101] Therefore, after UE101 measures RS1 and RS2, it sends a fourth message to base station 102 in time slot n+6 (i.e., n+4+2). The fourth message can be AMCCE, which reports RSRP = -100dBm for RS1 and RSRP = -105dBm for RS2.
[0102] Based on the received information, base station 102 determines RS1 as the optimal beam and instructs to use the RS1 (TCI state ID=1) beam to communicate with UE101.
[0103] Figure 6 This is a flowchart illustrating the overall process of the beam measurement method according to Embodiment 2 of this disclosure. Figure 6 As shown, the beam measurement method of Embodiment 2 of this disclosure includes at least the following execution entities: UE101 and base station 102, and the method may include at least the following steps.
[0104] Example 2:
[0105] 6.1 Base station 102 sends a first message to UE 101, wherein the first message may be RRC signaling. RRC may be used to instruct UE 101 to measure and / or report at least one reference signal.
[0106] Specifically, base station 102 can configure the first CSI reporting configuration through RRC signaling, wherein the first CSI reporting configuration can be associated with a reference signal resource set.
[0107] The associated reference signal resource set can be a periodic, semi-continuous, or aperiodic resource set. This resource set information can include at least one of the following: resource set index, reference signal index, period, and second time offset value. This resource set corresponds to the reference signal set set A used for prediction.
[0108] 6.2 Base station 102 sends a third message to UE101, wherein the third message may be DCI.
[0109] The DCI is primarily used for scheduling user data and controlling the downlink PDSCH and uplink PUSCH. UE101 needs to decode the DCI before decoding downlink data or transmitting uplink data.
[0110] Specifically, base station 102 can send a DCI instruction to the first trigger state, which is associated with the aforementioned first CSI reporting configuration.
[0111] 6.3 Base station 102 sends a second message to UE101, wherein the second message may be MACCE.
[0112] Base station 102 can instruct UE 101 to measure a subset of the aforementioned resource set by sending a MACCE. The MACCE may include at least the indication information of the reference signal index, wherein the indication information of the reference signal index may include at least one of the following: CSI reporting configuration index, reference signal resource set index, reference signal index; bitmap (the nth bit being 1 indicates that UE 101 wants to measure the nth reference signal in the resource set); the sequence number of the combination of reference signal indices, such as C N K One of the indices of the Top K reference signal combinations (N is the number of reference signals in the first resource set).
[0113] In other words, the reference signal resource set in this embodiment can also be understood as a complete set including all reference signals, and a subset of the resource set can be the set of reference signals corresponding to the unknown TCI in the Top K beam of the resource set.
[0114] 6.4 UE101 determines and measures. As described above, UE101 determines at least one reference signal based on the first message and / or the second message and / or the third message, and measures it, which can be understood as measuring the Top K beam of the unknown TCI.
[0115] 6.5 UE101 sends a fourth message to base station 102. The fourth message may include: MACCE, PUCCH, or PUSCH.

Figure 7 As shown, the beam measurement method of Embodiment 3 of this disclosure includes at least the following execution entities: UE101 and base station 102, and the method may include at least the following steps.
[0118] Example 3:
[0119] 7.1 Base station 102 sends a first message to UE 101, wherein the first message may be RRC signaling. RRC may be used to instruct UE 101 to measure and / or report at least one reference signal.
[0120] Specifically, base station 102 can configure the association information between the first trigger state and the CSI reporting configuration, and the association information between the first trigger state and the reference signal resource set through RRC signaling (e.g., the first trigger state, in which M CSI reporting configurations are associated, each CSI reporting configuration is associated with at least one resource set, of which only one resource set is associated with the first trigger state).
[0121] The association information between the first trigger state and the CSI reporting configuration, and the association information between the first trigger state and the reference signal resource set, include at least one of the following: CSI reporting configuration index; trigger state index; reference signal resource set index.
[0122] The resource set mentioned above is an aperiodic resource set, and the resource set configuration may include at least one of the following: resource set index, reference signal index, and second time offset value.
[0123] Each of the above resource sets may contain a small number of reference signals from the set A of reference signals used for prediction (e.g., only 2 of them).
[0124] 7.2 Base station 102 sends a third message to UE101, wherein the third message may be DCI.
[0125] Specifically, the DCI may include CSI request information, meaning that the base station 102 can trigger the first trigger state by sending a DCI indication.
[0126] 7.3 Base station 102 sends a second message to UE101, wherein the second message may be MACCE.
[0127] Specifically, base station 102 can update a subset of the M CSI reporting configurations associated with the first trigger state by sending a MACCE instruction, and / or update the resource set of the CSI reporting configuration associated with the first trigger state, and / or update the TCI state of the reference signal in the resource set associated with the first trigger state.
[0128] Among them, the multiple resource sets associated with the subset of M CSI reporting configurations contain the reference signal corresponding to the unknown TCI in the TopK beam. MACCE may include at least one of the following information: trigger state index, CSI reporting configuration index, and bitmap (the nth bit being 1 indicates triggering the nth CSI reporting configuration of the first trigger state).
[0129] In other words, the reference signal resource set in this embodiment can also be understood as a set of a small number of reference signals. One or more such resource sets can be combined to form the reference signal set corresponding to the unknown TCI in the Top K beam.
[0130] 7.4 UE101 determines and measures. As described above, UE101 determines at least one reference signal based on the first message and / or the second message and / or the third message, and measures it, which can be understood as measuring the Top K beam of the unknown TCI.
[0131] 7.5 UE101 sends a fourth message to base station 102. The fourth message may include MACCE, PUCCH, or PUSCH. As mentioned above, the fourth message includes the measurement result obtained in step 7.4. The measurement result is the same as in step 5.4 of Embodiment 1, and will not be repeated here.
[0132] 7.6 Base station 102 determines the optimal beam. That is, based on information such as different beam loads, L1-RSRP, and L1-SINR, base station 102 determines the optimal beam and instructs UE 101 to use a certain beam in Top K for communication.
[0133] In one example embodiment, base station 102 associates 16 CSI reporting configurations with trigger state ID=1 via RRC configuration. Each CSI reporting configuration ID from 1 to 16 is associated with an aperiodic resource set. Therefore, the resource sets contain the following reference signals:
[0134] {Resource set 1, RS ID = 1~4}, {Resource set 2, RS ID = 5~8}, ..., {Resource set 16, RS ID = 61~64}, the second time offset of the resource set = 4 time slots.
[0135] Based on the AI model prediction, UE101 obtained the top 5 beams as RS ID = 6, 7, 8, 9, 10, where RS ID = 6, 7, 9, 10 are unknown TCIs.
[0136] Base station 102 sends a DCI indication trigger state ID=1 in time slot n, and sends a MACCE indication trigger state ID=1 in time slot n+1 to trigger CSI reporting configuration ID=2 and 3.
[0137] After UE101 measures RS IDs 5 to 12 in time slot n+4, it reports RSRP = -100dBm for RS 6, RSRP = -102dBm for RS 7, RSRP = -103dBm for RS 9, and RSRP = -105dBm for RS10 in time slot n+8.
[0138] Base station 102 indicates that it will use the RS 6 (TCI state ID=6) beam to communicate with UE101.
[0139] Figure 8 This is a flowchart illustrating the overall process of the beam measurement method according to Embodiment 4 of this disclosure. Figure 8 As shown, the beam measurement method of Embodiment 4 of this disclosure includes at least the following execution entities: UE101 and base station 102, and the method may include at least the following steps.
[0140] 8.1a. Base station 102 sends a third message to UE 101, wherein the third message may be DCI.
[0141] Specifically, DCI can indicate TCI state.

[0143] Specifically, MACCE can indicate the TCI state.
[0144] 8.2 UE101 determines and measures. As described above, UE101 determines at least one reference signal based on the second or third message mentioned above. The terminal device assumes that the network device sends at least one reference signal and measures it, which can be understood as measuring the Top K beam of the unknown TCI.
[0145] 8.3 UE101 sends a fourth message to base station 102. The fourth message may include: MACCE, PUCCH, or PUSCH.
