This application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, for example, it may include LTE protocols, NR protocols, and related protocols used in future communication systems, and this application does not limit this.

[0055] The design goals of NR / 5G systems include wide-bandwidth communications in high-frequency bands (e.g., bands above 6 GHz). As the operating frequency increases, path loss during transmission increases, affecting the coverage capabilities of high-frequency systems. To effectively ensure high-band NR system coverage, an effective technical solution is to use multiple beam or hybrid beam technologies based on massive antenna arrays or massive multiple-input multiple-output (MIMO) to improve coverage.

[0056] In typical 2G / 3G / 4G systems, a cell (sector) uses a wide beam to cover the entire cell. Therefore, at every moment, UEs within the cell's coverage area have the opportunity to obtain transmission resources allocated by the system.

[0057] The NR / 5G Multi-beam system uses different beams to cover the entire cell, that is, each beam covers a smaller range, and the effect of multiple beams covering the entire cell is achieved through time scanning (sweeping). Currently, different beams are identified by the different signals carried on them. Optionally, different SS blocks (or also called synchronization signals / physical broadcast channel blocks (Synchronization Signal / Physical Broadcast Channel Block, SS / PBCH block)) are transmitted on some different beams, and the UE can distinguish different beams through different SS blocks and / or SS block resources. Optionally, different channel state information reference signals (Channel State Information Reference Signal, CSI-RS) signals are transmitted on some different beams, and the UE identifies different beams through CSI-RS signals / CSI-RS resources.

[0058] In any embodiment of the present application, the SS / PBCH block may be referred to as a synchronization signal block (Synchronization Signal Block, SSB).

[0059] The signal in any one or some embodiments of the present application corresponds to a certain physical beam.

[0060] In a multi-beam system, PDCCH and PDSCH can be transmitted through different downlink transmit beams.

[0061] Optionally, for systems below the 6G frequency band, there is generally no analog beam on the UE side, so an omnidirectional antenna (or a nearly omnidirectional antenna) is used to receive signals sent by different downlink transmission beams of the base station.

[0062] Optionally, for millimeter wave systems, the UE may have analog beams, requiring the corresponding downlink receive beam to receive the signal sent by the corresponding downlink transmit beam. In this case, beam indication information is required to assist the UE in determining the network's transmit beam information or the UE's corresponding receive beam information.

[0063] In the NR protocol, the beam indication information does not directly indicate the beam itself, but is indicated by the QCL quasi-co-location between signals (for example, 'QCL-TypeD' type). On the UE side, the determination of receiving the corresponding channel / signal is also based on the QCL quasi-co-location assumption. The QCL quasi-co-location assumption is indicated by the Transmission Configuration Indication (TCI) state (TCI-state), that is, the network configures and / or indicates the TCI state through relevant signaling (Radio Resource Control (RRC), and / or Medium Access Control Element (MAC CE), and / or Downlink Control Information (DCI)).

[0064] Future communication systems (such as 6G wireless communication systems and the new generation of Wi-Fi) can also adopt multi-beam technology.

[0065] In order to perform good beam management (for example, the network selects a better downlink transmit beam (DL Tx beam) to transmit signals to a user UE), the communication system needs to know the communication quality corresponding to the beam, which involves how to measure and report the beam (or reference signal). In an actual system, the network may not directly instruct the UE to measure a certain beam. It may use the beam to transmit a reference signal (RS) and let the UE measure the RS. The measurement result corresponding to the RS can reflect the transmission quality corresponding to the beam. Therefore, from the perspective of network and terminal interaction, the UE may only know that there are more RSs for measurement, and does not know whether they are associated with a beam. If they are associated with a beam, it does not know which beam they are associated with.

[0066] In some embodiments, measuring the RS may not only be for assisting beam management, but may also be for measuring current channel information to assist MIMO transmission.

[0067] In the 5G system, the basic process of measurement and reporting is as follows: the network sends configuration information to the UE, which indicates one or more RSs and some measurement-related configurations; the UE measures the corresponding reference signals based on the received configuration information and obtains the measurement results that need to be reported (the measurement results may not need to be reported); if the measurement results need to be reported, the UE reports the corresponding measurement results through the uplink channel.

[0068] In some embodiments, RS transmission can take different forms, such as aperiodic (AP), semi-persistent (SP), and periodic (P) transmission. In some embodiments, measurement result reporting supports multiple mechanisms, including aperiodic (AP), semi-persistent (SP), and periodic (P) reporting.

[0069] The following is a description of the TCI state:

[0070] To improve reception performance, terminal devices can leverage the characteristics of the transmission environment to improve their reception algorithms. For example, channel statistics can be used to optimize the design and parameters of the channel estimator. In NR systems, these characteristics of data transmission are represented by the QCL state (QCL-Info).

[0071] If the downlink transmission comes from different TRPs / panels / beams, the characteristics of the transmission environment corresponding to the data transmission may also change. Therefore, in the NR system, when the network side transmits the downlink control channel or data channel, it will indicate the corresponding QCL status information to the terminal device through the TCI state.

[0072] Among them, a TCI state can include the following configurations:

[0073] TCI state ID, used to identify a TCI state;

[0074] QCL information 1;

[0075] QCL information 2 (optional).

[0076] Among them, a QCL information contains the following information:

[0077] QCL type configuration, which can be one of QCL type A, QCL type B, QCL type C, and QCL type D;

[0078] The QCL reference signal configuration includes the cell ID where the reference signal is located, the bandwidth part (Band Width Part, BWP) ID, and the reference signal identifier (which can be a CSI-RS resource ID or SSB index).

[0079] Among them, if QCL information 1 and QCL information 2 are both configured, the QCL type of one or more QCL information is one of typeA, typeB, and typeC, and the QCL type of the other QCL information (if configured) is QCL type D.

[0080] The definitions of different QCL type configurations are as follows:

[0081] 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0082] 'QCL-TypeB': {Doppler shift, Doppler spread};

[0083] 'QCL-TypeC': {Doppler shift, average delay};

[0084] 'QCL-TypeD': {Spatial Rx parameter}.

[0085] In the NR system, the network side can indicate the corresponding TCI status for the downlink signal or downlink channel.

[0086] If the network side configures the QCL reference signal of the target downlink channel or target downlink signal as a reference SSB or reference CSI-RS resource through the TCI state, and the QCL type is configured as typeA, typeB or typeC, the terminal device can assume that the large-scale parameters of the target downlink signal and the reference SSB or reference CSI-RS resource are the same, and the large-scale parameters are determined by the QCL type configuration.

[0087] Similarly, if the network side configures the QCL reference signal of the target downlink channel or downlink signal as a reference SSB or reference CSI-RS resource through the TCI state, and the QCL type is configured as typeD, the terminal device can use the same receiving beam (ie, Spatial Rx parameter) as that for receiving the reference SSB or reference CSI-RS resource to receive the target downlink signal. Typically, the target downlink channel (or downlink signal) and its reference SSB or reference CSI-RS resource are sent by the same TRP or the same panel or the same beam on the network side. If the transmission TRP or transmission panel or transmission beam of two downlink signals or downlink channels is different, different TCI states are usually configured.

[0088] For the downlink control channel, the TCI status of the corresponding CORESET may be indicated by RRC signaling or RRC signaling + Medium Access Control (MAC) signaling.

[0089] For downlink data channels, the set of available TCI states is indicated by RRC signaling, and some of these TCI states are activated by MAC layer signaling. Finally, the TCI state indication field in the DCI indicates one or two TCI states from the activated TCI states for the PDSCH scheduled by the DCI. The case of two TCI states is mainly for scenarios with multiple TRPs.

[0090] FIG2 is a schematic diagram of a method for configuring TCI states for a PDSCH provided in an embodiment of the present application. As shown in FIG2 , N candidate TCI states can be determined through RRC signaling. For example, RRC signaling can indicate N candidate TCI states. K activated TCI states can be determined from the N candidate TCI states through MAC signaling. One or two used TCI states can be determined from the K activated TCI states through DCI signaling.

[0091] The following describes the Unified TCI state:

[0092] The TCI state indication mechanism was introduced in Release 15 and is only applicable to downlink channels and signals. It has many limitations in NR systems. To provide a more unified uplink and downlink beam management mechanism for NR systems, 3GPP Release 17 proposed the concept of a unified TCI state, based on the design of Rel. 15 / 16 TCI states. It adds important new features, such as the following:

[0093] Two unified TCI state modes are designed:

[0094] Mode 1: Includes one TCI state, which is applicable to both uplink and downlink channels and signals. This TCI state is called a joint TCI state.

[0095] Mode 2: Contains two types of TCI states, where the DL TCI state applies only to downlink channels and signals; the UL TCI state applies only to uplink channels and signals.

[0096] Downlink channels (partial PDCCH, PDSCH) and signals (aperiodic CSI-RS) use the same downlink transmit indicator beam and use the DL TCI state or joint TCI state.

[0097] Uplink channels (PUCCH, PUSCH) and signals (SRS) use the same uplink transmit beam and use the UL TCI state or joint TCI state.

[0098] The Unified TCI state can be dynamically updated and indicated using MAC CE and / or DCI.

[0099] The Unified TCI state is applicable to carrier aggregation scenarios, and the beam indication on a single CC can be applied to multiple different CCs.

[0100] The uplink beam indication can be given simultaneously with the uplink power control parameters through the UL TCI state or joint TCI state.

[0101] Unified TCI state supports inter-cell beam management.

[0102] The CORESETs on each CC can be roughly divided into the following four types in the 3GPP discussion:

[0103] CORESET A: It is associated only with the terminal device's dedicated search space and can be considered as a terminal device's dedicated downlink control channel resource and must follow the indicated unified TCI state(s);

[0104] CORESET B: It is associated only with the cell-common search space. Whether it can follow the unified TCI state(s) indicated by the network (NW) depends on the RRC configuration of the NW.

[0105] CORESET C: It is associated with both the terminal device-specific search space and the cell-common search space. Whether it can follow the unified TCI state(s) indicated by the network worker network (NW) depends on the NW RRC configuration.

[0106] CORESET 0: It must be associated with the common search space of the cell, and can also be associated with the terminal device-specific search space. Whether it can follow the unified TCI state(s) indicated by the NW depends on the RRC configuration of the NW.

[0107] The TCI state in the embodiments of the present application, if the TCI state is not explicitly specified, includes any of the TCI states mentioned above. For example, the TCI state can be a joint TCI state, a separate TCI state, a DL TCI state, a UL TCI state, or a combination thereof (i.e., including multiple different types of TCI states, such as one or more of the DL TCI state, UL TCI state, joint TCI state, and separate TCI state), or the TCI state in R15 / R16.

[0108] In the related art, in the measurement / reporting mechanism, the network configures the corresponding RS (reference signal) group that needs to be measured through RRC signaling. For periodic reporting or semi-continuous reporting, the UE measures the RS group configured by RRC; for non-periodic reporting, the UE measures one or some RS groups in one or more RS groups configured by RRC according to the activation state (trigger state) indicated by DCI. As can be seen from the above, the RS groups measured by the UE are all configured by RRC. If the system wants the UE to measure a group of RS that is not currently included in the RS group already configured by RRC, then the network needs to configure the said group of RS through RRC signaling.

[0109] In actual systems, in some cases, the network wants the UE to dynamically measure certain RSs. For example, in a multi-beam system (assuming there are 16 simulated beams), the network infers based on certain information or methods that the channel quality (or link quality) of beams numbered 0-3 is most likely the best for a certain UE, while the channel quality of other beams is not good for the UE. In this case, the network can only allow the UE to measure beams numbered 0-3. Then, as the UE moves, at the next moment, the network infers that the channel quality (or link quality) of beams numbered 2-5 is most likely the best for a certain UE, while the channel quality of other beams is not good for the UE. In this case, the network can only allow the UE to measure beams numbered 2-5. In this scenario, it is necessary to flexibly instruct the UE to measure different signals.

[0110] If the existing related technical mechanisms are adopted, the following processing methods can be used:

[0111] In some embodiments, various RS groups composed of different RSs are pre-configured via RRC, and then aperiodic reporting is triggered via DCI to achieve measurement and reporting of different RS groups. This approach has many disadvantages, such as: 1. High RRC signaling overhead, requiring the UE to process a large number of RS groups, increasing UE complexity; 2. More bits are required in the DCI to indicate different RS groups, resulting in an increase in the DCI size, which affects control channel coverage.

[0112] In some embodiments, the currently required RS group is configured via RRC. This approach also has many disadvantages, such as: 1. Frequent RRC signaling transmissions lead to high RRC signaling overhead; 2. RRC signaling configuration causes large delays, which can prevent the network from enabling the UE to quickly measure certain RSs, affecting overall system performance.

[0113] In the above cases, the network can use a variety of different methods to infer which beams have better channel quality for a particular UE, for example:

[0114] In some embodiments, the network uses machine learning (ML), artificial intelligence (AI), or statistical methods to predict based on information reported by the UE and / or information obtained through other means (e.g., measurement results obtained by the network on UE signal transmission or uplink transmission). Deep learning is a commonly used AI method.

[0115] In some embodiments, the UE uses machine learning (ML) methods, artificial intelligence (AI) methods, or statistical methods to predict several beams that may be best for itself based on its own measurement results, and then reports the prediction results to the network.

[0116] This use of AI / ML technology to assist beam management can be collectively referred to as AI-based beam management. Whether AI / ML technology is used, or which AI / ML technology is used, may be invisible from the perspective of the network and the terminal. That is, one party (such as the UE or the network) may not know which AI / ML technology the other party (such as the network or the UE) is using. In addition to using AI / ML technology, the network or the UE can also use non-AI / ML technology (non-AI / ML) to implement similar functions or achieve similar effects.

[0117] This application introduces a more flexible measurement and / or reporting mechanism. In response to the above requirements, the present invention proposes a specific implementation solution.

[0118] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The solutions in any one or more of the above embodiments can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0119] An embodiment of the present application provides a communication method, which may include: a terminal device receiving first configuration information, where the first configuration information indicates one or more resource groups.

[0120] Optionally, the communication method may also include: the terminal device receives first indication information; the first indication information indicates one or more subgroups of the first resource group, each subgroup of the one or more subgroups of the first resource group includes one or more resources in the first resource group; the first resource group belongs to a resource group among the one or more resource groups.

[0121] Optionally, the first indication information is included in a media access control element MAC CE or downlink control information DCI.

[0122] Optionally, when the first indication information indicates a subgroup of the first resource group, the subgroup of the first resource group is the first subgroup.

[0123] Optionally, the communication method may further include: the terminal device receives second indication information; the second indication information indicates a first subgroup of the first resource group, and the first subgroup belongs to one or more subgroups of the first resource group.

[0124] Optionally, the second indication information is included in DCI.

[0125] FIG3 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG3 , the method is applied to a terminal device, and the method includes:

[0126] S301. The terminal device receives first configuration information; the first configuration information is transmitted through radio resource control RRC signaling, and the first configuration information indicates one or more resource groups.

[0127] S302. The terminal device receives first indication information; the first indication information is included in a media access control element MAC CE or downlink control information DCI, the first indication information indicates one or more subgroups of a first resource group, each subgroup of the one or more subgroups of the first resource group includes one or more resources in the first resource group; the first resource group belongs to a resource group among the one or more resource groups.

[0128] For example, for the NR system, a resource group can be configured through RRC signaling non-zero power CSI-RS resource group (Non-Zero-Power-CSI-RS-ResourceSet, NZP-CSI-RS-ResourceSet), and the resources can be indicated by RRC signaling non-zero power CSI-RS resources (Non-Zero-Power-CSI-RS-Resource, NZP-CSI-RS-Resource).

[0129] It should be noted that in the existing method, the terminal device performs measurement and / or reporting based on the corresponding resource group according to the configuration information and / or indication information (e.g., RRC, or RRC+DCI) of the network device. In this solution, on this basis, the terminal device can also perform measurement and / or reporting based on one or more corresponding subgroups in the corresponding resource group according to the configuration information and / or indication information of the network device.

[0130] Optionally, the first indication information indicates activation of one or more subgroups of the first resource group. Optionally, the first indication information indicates deactivation of one or more subgroups of the first resource group.

[0131] Optionally, one or more subgroups of the activated first resource group are used for measurement and / or reporting by the terminal device. For example, the resources in the first resource group include resources 0 to resource 4, and the resources of the activated one or more subgroups of the first resource group include resource 0, resource 1 and resource 2, then the terminal device performs measurement and / or reporting on resource 0, resource 1 and resource 2. For another example, if the activated one or more subgroups of the first resource group include the first subgroup, then the terminal device performs measurement and / or reporting on the first subgroup. For another example, if the activated one or more subgroups of the first resource group include the first subgroup, the fourth subgroup and the fifth subgroup, then the terminal device performs measurement and / or reporting on the first subgroup, the fourth subgroup and the fifth subgroup.

[0132] Optionally, resources and / or subgroups other than the one or more deactivated subgroups in the first resource group are used for measurement and / or reporting by the terminal device. For example, the resources in the first resource group include resources 0 to resource 4, and the resources of the one or more deactivated subgroups of the first resource group include resources 2, resources 3, and resources 4, then the terminal device performs measurement and / or reporting on resource 0 and resource 1. For another example, the first resource group includes the first subgroup, the fourth subgroup, and the fifth subgroup, and the one or more deactivated subgroups of the first resource group include the fourth subgroup and the fifth subgroup, then the terminal device performs measurement and / or reporting on the first subgroup.

In this way, the terminal device can receive one or more subgroups in the first resource group indicated by the network device, so that the terminal device can perform measurements based on the one or more subgroups in the first resource group, and the resources indicated by the network device to the terminal device are flexible.

[0150] Optionally, the first subgroup, second subgroup, and third subgroup in the embodiments of the present application are merely for convenience of description. In some embodiments, the first subgroup, second subgroup, and third subgroup may not be explicitly defined. For example, the first information indicating the first subgroup of the first resource group, wherein the first subgroup includes one or more resources in the first resource group, can be replaced by: the first information indicating one or more resources in the first resource group. For convenience of description, one or more resources in the first resource group are described as the first subgroup.

[0164] In some embodiments, the first indication information further indicates a first bandwidth part BWP, and / or the first indication information is applied to the first BWP.

[0166] In some embodiments, the first indication information further indicates a first non-periodic activation state; the first non-periodic activation state indicates a first set or the first resource group; and the first resource group belongs to a resource group among one or more resource groups in the first set.

[0167] In some embodiments, the one or more subgroups include a first subgroup, and the first indication information is included in a MAC CE or a DCI.

[0168] In some embodiments, the one or more resources contained in a subgroup (e.g., one or more items in the first subgroup, the second subgroup, and the third subgroup) are indicated by a bitmap; and / or, the one or more resources contained in a subgroup (e.g., one or more items in the first subgroup, the second subgroup, and the third subgroup) are indicated by numbers; and / or, the one or more resources contained in a subgroup (e.g., one or more items in the first subgroup, the second subgroup, and the third subgroup) are indicated by resource identification IDs.

[0169] For example, the one or more resources included in the first subgroup are indicated by a bitmap; and / or, the one or more resources included in the first subgroup are indicated by numbers; and / or, the one or more resources included in the first subgroup are indicated by a resource identifier ID.

[0170] Optionally, one / each bit corresponds to T resources. Optionally, T is an integer greater than or equal to 1. Optionally, the number of resources corresponding to different bits can be the same or different. Optionally, the value of T is configured by the network. Optionally, the value of T is specified by the protocol. Optionally, by corresponding one / each bit to T resources, the number of corresponding DCI bits can be reduced.

[0171] Optionally, since one or more resources are indicated by a bitmap, signaling overhead can be reduced when the number of resources in the subgroup is relatively large, or when the number of resources in the first resource group and / or the second resource group and / or the third resource group is relatively large.

[0172] Optionally, the number is the number of the resource in the first resource group and / or the second resource group and / or the third resource group. For example, 0 may correspond to the first resource in the first resource group, and 1 may correspond to the second signal in the first resource group.

[0173] Optionally, since one or more resources are indicated by numbers, signaling overhead can be reduced when the number of resources in the subgroup is relatively small, or when the number of resources in the first resource group is relatively small.

[0174] Optionally, the resource identifier is an identifier in the resource configuration information. For example, if the resource is a CSI-RS resource (because the CSI-RS resource here is to actually transmit the CSI-RS signal, it can also be called NZP-CSI-RS-Resource, where NZP refers to Non-Zero-Power), then in the NR system the resource identifier is nzp-CSI-RS-ResourceId.

[0175] Optionally, since one or more resources are indicated by a resource identifier ID, directly using the identifier of the CSI-RS resource itself can simplify UE processing. However, the disadvantage is that the overhead of RRC signaling may be increased.

[0278] Optionally, each of the one or more subgroups indicates which resources in the first resource group belong to the subgroup by indicating one or more numbers, where the numbers are numbers of resources within the first resource group, for example, 0 may correspond to the first resource in the first resource group, and 1 may correspond to the second resource in the first resource group.

[0279] Optionally, each of the one or more subgroups indicates which resources in the first resource group belong to this subgroup by indicating one or more identifiers, wherein the identifier is an identifier in the resource configuration information. For example, if the resource is a CSI-RS resource (because the CSI-RS resource here is to actually send a CSI-RS signal, it can also be called NZP-CSI-RS-Resource, NZP refers to non-zero-power), then the identifier in the NR system is nzp-CSI-RS-ResourceId.

[0434] Optionally, in this way, by defining a default behavior when the UE does not receive relevant indication information, additional signaling design can be reduced.

[0435] In some embodiments, the reporting performed by the terminal device includes one or more of the following: the terminal device performs non-periodic reporting, the terminal device performs periodic reporting, and the terminal device performs semi-continuous reporting.

[0436] Optionally, the reporting in any embodiment of the present application is applicable to aperiodic (AP) reporting. In this way, aperiodic reporting has the highest flexibility. Adding flexible subgroup-based indication on this basis can further improve system flexibility. At the same time, if periodic and semi-continuous reporting are not adopted, the complexity of network and terminal implementation can be reduced.

[0437] Optionally, the reporting in any embodiment of the present application is applicable to periodic (P) reporting.

In this way, flexible indication based on subgroups is introduced for all reporting methods to improve system flexibility.

[0440] Optionally, the reporting in any embodiment of the present application is applicable to periodic (P) reporting and semi-persistent (SP) reporting. Compared with aperiodic reporting, periodic reporting and semi-persistent reporting are relatively less flexible. Introducing flexible subgroup-based indication can improve system flexibility.

[0441] Optionally, in any embodiment of the present application, the corresponding reporting result reported by the terminal device may be the first result.

[0442] In some embodiments, the first result reported by the terminal device includes one or more of the following, and / or the first result received by the network device includes one or more of the following:

[0443] Measurement results; the measurement results include one or more of the following: measured parameter information, measured signal identification, measured signal resource identification;

[0444] Prediction result; the prediction result includes one or more of the following: predicted signal, predicted signal resource; predicted signal identifier, predicted signal resource identifier, predicted parameter information corresponding to the predicted signal, predicted parameter information corresponding to the predicted signal resource;

[0445] Third indication information; the third indication information is used to indicate that the first result includes the measurement result and / or the prediction result;

[0446] The parameter information includes one or more values ​​of the following: L1-RSRP, L1-SINR, RSRP, and SINR.

[0447] Optionally, in the first result, the signal or signal resource has measured parameter information and predicted parameter information. Optionally, when a signal or signal resource corresponds to measured parameter information and predicted parameter information, the first result includes the measured parameter information and / or predicted parameter information of the signal or signal resource.

[0448] Optionally, the first result includes the measurement result and / or prediction result, and is determined based on fourth indication information sent by the network device to the terminal device, or based on whether the network device sends fourth indication information to the terminal device.

[0449] Optionally, the first result may include the following options:

[0450] Option 1: The first result includes a measurement result, such as the measured L1-RSRP, and / or a corresponding signal identifier or signal resource identifier (for example, one identifier indicates a CSI-RS resource, and for another example, the identifier indicates an SSB). In addition to L1-RSRP, it can also be L1-SINR. In this way, the terminal device performs measurements based on one or more subgroups and reports the measurement results to the network device. The network device can determine the subsequent beam management operations based on appropriate algorithms or rules (such as deep learning algorithms, AI algorithms, machine learning algorithms, statistical algorithms, etc., the specific algorithms are not limited), for example, allowing the terminal device to perform beam measurements, or configuring some beams for the terminal device, or instructing the terminal device to use one or some beams for transmission, thereby improving the overall performance of the network device.

[0451] Option 2: The first result includes the prediction result of the terminal device, for example, the signal (or signal resource) predicted by the terminal device. Optionally, the predicted signal / signal resource can be reported by an identifier (for convenience of expression, it is called a predicted identifier) ​​(for example, a predicted identifier indicates a predicted CSI-RS resource, and for another example, the identifier indicates a predicted SSB). Optionally, the first result can also include the RSRP value predicted by the terminal device (or L1-RSRP value), wherein the predicted RSRP value corresponds to the predicted signal or signal resource. In addition to L1-RSRP, it can also be L1-SINR. In this way, the terminal device performs measurements based on one or more subgroups, and then it can use appropriate algorithms or rules (such as deep learning algorithms, AI algorithms, machine learning algorithms, statistical algorithms, etc., the specific algorithms are not limited) to determine which beams are most beneficial to itself, and report these predicted beams to the network device, which can assist the network device in making better beam management and improving the performance of the network device.

[0452] Option 3: is a combination of options 2 and 1. That is, the first result includes both the measured L1-RSRP and the predicted L1-RSRP. As an example, the first result may include additional information (i.e., the third indication information mentioned above), and the additional information is used to indicate whether a certain L1-RSRP is a measurement result or a prediction result. As another example, according to a third predetermined rule in advance (the implementation method may be different methods such as protocol provisions or network device configuration), such as the arrangement position in the reported information, it is indicated whether a certain L1-RSRP is a measurement result or a prediction result. In addition to L1-RSRP, L1-SINR can also be used. In this way, in some cases, the L1-RSRP measured by the terminal device itself may be more accurate than the predicted one. Reporting the measured L1-RSRP to the network device can assist the network device in making better beam management and improving the performance of the network device.

[0453] Optionally, in the first result, a signal or signal resource may have both a corresponding measured L1-RSRP and a predicted L1-RSRP. In other embodiments, L1-RSRP may be replaced with L1-SINR. This allows more information to be reported to the network device, helping it to perform better beam management and improve network device performance.

[0454] Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, the report of the first result includes the measured L1-RSRP corresponding to the signal or signal resource. In other embodiments, the L1-RSRP here can also be replaced by L1-SINR. In this way, in some cases, the L1-RSRP measured by the terminal device itself may be more accurate than the predicted one. Reporting the measured L1-RSRP to the network device can assist the network device in making better beam management and improving the performance of the network device.

[0455] Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, the report of the first result includes the predicted L1-RSRP corresponding to the signal or signal resource. In other embodiments, the L1-RSRP here can also be replaced by L1-SINR. In this way, the terminal device reports the predicted L1-RSRP corresponding to this signal resource, which can facilitate the network device to better compare the quality of different beams (reference resources) because they are all predicted, thereby facilitating the network device to make better beam management and improve network device performance.

[0456] Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, it is determined based on the fourth indication information whether the report of the first result includes the measured L1-RSRP corresponding to the signal or signal resource, or the predicted L1-RSRP corresponding to the signal or signal resource. The fourth indication information is sent by the network device to the terminal device. In other embodiments, the L1-RSRP here can also be replaced by L1-SINR. In this way, the network device uses signaling to clarify whether the terminal device reports the predicted L1-RSRP or the measured L1-RSRP, thereby providing the network device with greater freedom.

[0457] Optionally, it is determined according to the fourth indication information, and may be determined according to the value of the fourth indication information.

[0458] Optionally, the determination is based on the fourth indication information, which may be based on whether the network device has sent or configured the fourth indication information.

[0459] In some embodiments, on the terminal device side, the method further includes: the terminal device reporting a first terminal capability; the first terminal capability indicates a capability of the terminal device related to a subgroup in a resource group.

[0460] In some embodiments, on the network device side, the method further includes: the network device receiving a first terminal capability; the first terminal capability indicates a capability of the terminal device related to a subgroup in the resource group.

[0461] In some embodiments, the first terminal capability indicates one or more of the following: configuring a subgroup in a resource group through RRC; indicating one or more subgroups through MAC CE; indicating one or more subgroups through DCI; supporting subgroup-based measurement; supporting subgroup-based reporting.

[0462] Optionally, the terminal device reports a first terminal capability to the network device, where the first terminal capability indicates all or part of the above-mentioned subgroup-related capabilities of the terminal device (for example, RRC can configure a subgroup for a resource group, and / or MAC CE can indicate one or more subgroups, and / or DCI signaling can indicate one or more subgroups, and / or the terminal can support subgroup-based measurement, and / or the terminal can support subgroup-based reporting).

[0463] In some embodiments, the first terminal capability is transmitted via RRC transmission or MAC CE transmission.

[0464] In some embodiments, the first terminal capability is reported for a frequency band; or

[0465] The first terminal capability is reported for each carrier on the frequency band; or,

[0466] The first terminal capability is reported for a frequency band combination; or

[0467] The first terminal capability is reported for each frequency band in the frequency band combination; or,

[0468] The first terminal capability is reported for each carrier on each frequency band in the frequency band combination; or,

[0469] The first terminal capability is reported for a frequency band range; or,

[0470] The first terminal capability is reported for the UE.

[0471] Optionally, the first terminal capability is reported for the frequency band (i.e., different frequency bands can independently report corresponding capabilities, per band). In this way, independent reporting of different frequency bands can allow the terminal to have greater freedom. For example, the terminal can support one or some bands, but not support this function on other bands, thereby allowing more terminals to support this new function.

[0472] Optionally, the first terminal capability is reported independently according to the band combination (per band combination). In this way, different band combinations are reported independently, which allows the terminal to have greater freedom. For example, the terminal may not support this function under a certain band combination, but support this function under another band combination, thereby allowing more terminals to support this new function.

[0473] Optionally, the first terminal capability is reported independently according to each frequency band in the band combination (that is, the frequency bands in different frequency band combinations can be reported independently, per band per band combination). In this way, different frequency band combinations are reported independently, allowing the terminal to have greater freedom. For example, the terminal may not support this function under a certain CA, but some bands under another CA combination may support this function, thereby allowing more terminals to support this new function.

[0474] Optionally, the first terminal capability is reported independently according to each carrier on each frequency band in the frequency band combination (that is, different carrier CCs in frequency bands in different frequency band combinations can be reported independently, per CC per band per band combination, or FSPC). In this way, different frequency band combinations are reported independently, and different carriers on a band can also be reported independently, which allows the terminal to have greater freedom, thereby allowing more terminals to support this new function.

[0475] Optionally, the first terminal capability is reported according to the frequency range (i.e., different FRs can be reported independently, per FR, i.e., FR1 and FR2 are reported independently). In this way, independent reporting of different FRs can allow the terminal to have greater freedom. For example, the terminal does not support this function in the low frequency (FR1), but supports this function in FR2 (high frequency), thereby allowing more terminals to support this new function.

[0476] Optionally, the first terminal capability is reported per UE (ie, per UE, that is, if the UE reports this capability, this capability can be supported on all frequency bands). In this way, the signaling overhead of reporting the terminal capability is reduced.

[0483] In some embodiments, resources in one or more resource groups in the first set are associated with a second serving cell, and / or resources in one or more resource groups in the second set are associated with a third serving cell.

[0484] Optionally, the resources in one or more resource groups in the first set are associated with the second service cell, including: the resources in one or more resource groups in the first set belong to the second service cell, that is, the resources in one or more resource groups in the first set are resources in the second service cell.

[0524] Some embodiments of the present application are described below:

[0525] Regarding the embodiment of the first configuration information:

[0526] A first terminal device (UE) receives first configuration information sent by a network device, where the first configuration information indicates a first set, where the first set includes one or more resource groups (sets), where each resource group (Resource Set) includes one or more resources, and the resources may correspond to a signal (e.g., SSB), a reference signal (e.g., CSI-RS), or a reference signal resource (e.g., CSI-RS resource). Therefore, the resource group may also be referred to as a signal resource group (A set of RS resources, or RS resource set).

[0527] Optionally, the first configuration information is transmitted via RRC signaling, so that the protocol design is simple and the reliability is high.

[0528] Optionally, the first configuration information belongs to a first serving cell (or carrier), that is, the first configuration information belongs to configuration information in the first serving cell.

[0529] Optionally, the resources in the one or more resource groups in the first set belong to the second serving cell, that is, the resources in the one or more resource groups in the first set are resources in the second serving cell.

[0530] Optionally, the first serving cell and the second serving cell are the same serving cell, that is, the first configuration information configures resources in the same cell. In this way, the configuration information and the resources are in the same serving cell, which can effectively reduce the processing complexity of the system (including the UE), thereby reducing the difficulty of product implementation.

[0531] Optionally, the first serving cell and the second serving cell are different serving cells, that is, the first configuration information configures resources in other cells. In this way, system flexibility can be increased, that is, the UE can measure resources (e.g., signal resources) of other cells and then report the measurement results from the other cell, thereby improving overall system performance.

[0532] For example, when the resource corresponds to a reference signal resource or a reference signal, the first configuration information may indicate part or all of the following corresponding information (corresponding to the reference signal resource or reference signal information):

[0533] Type of signal / reference signal;

[0534] Signal / reference signal identification or number;

[0535] Resources corresponding to the signal / reference signal (e.g., frequency domain resources, time domain resources, or time-frequency domain resources);

[0536] Power information corresponding to the signal / reference signal;

[0537] Scrambling information corresponding to the signal / reference signal, for example, the scrambling information is used to generate a signal / reference signal sequence;

[0538] QCL information corresponding to the signal / reference signal, or TCI-state information;

[0539] Optionally, in the NR system (when NR is taken as an example in this application, the corresponding technical solution is not limited to NR, and can also be used in other communication systems. It is similar in other places and will not be repeated here), each resource group in the one or more resource groups in the first set can indicate one or more CSI-RS resources, or can indicate one or more SSBs (SS / PBCH blocks, synchronization signal blocks), or can indicate CSI-RS resources (one or more) and SSBs (one or more) at the same time. Assuming that a resource group is marked as ResourceSet, a group of resources can be indicated by a sequence (SEQUENCE) structure (a structure of RRC signaling), for example, SEQUENCE (SIZE (1. Maximum number of resources in the group)) OF resource-related information.

[0540] Optionally, the resource-related information can have different options, such as:

[0541] Option 1: The resource-related information indicates a CSI-RS resource;

[0542] Option 2: The resource-related information indicates an SSB (or SS / PBCH block);

[0543] Option 2: The resource-related information indicates an SSB (or SS / PBCH block) or a CSI-RS resource;

[0544] Optionally, each resource group in the first set is used for channel measurement, or for beam measurement, or for both channel measurement and beam measurement. In this way, channel measurement and beam measurement can be completed simultaneously, reducing system overhead. It can also be said that the resources in one or more resource groups in the first set, or the reference signals (or reference signal resources) are used for channel measurement, or for beam measurement, or for both channel measurement and beam measurement. For example, the UE can perform channel measurement and / or beam measurement based on the above resource groups, and on this basis, the UE may further report the measurement results to the network. For another example, in the NR system, if one of the resource groups above indicates a CSSI-RS resource, the value of the field "repetition" in the RRC signaling corresponding to the resource group configuration can be "on" or "off".

[0545] Optionally, the first configuration information may further indicate reporting of L1-RSRP, or L1-SINR, or RSRP, or SINR. For example, in an NR system, the first configuration information may contain a field "reportQuantity", whose value may be cri-RSRP, or ssb-Index-RSRP, or cri-SINR, or ssb-Index-SINR.

[0546] Optionally, the first configuration information only indicates the first set. For example, when the first configuration information indicates the first set (but does not indicate the second set and the third set mentioned later), the terminal device can perform channel measurement based on one or more resource groups in the first set according to the network configuration information, and can also report these measurement results to the network (for example, RSRP results or L1-RSRP results can be reported).

[0547] Let's start describing the second set:

[0548] Optionally, based on the above, the first configuration information may also indicate a second set, where the second set includes one or more resource groups, and the resources in the second set may correspond to a signal (e.g., SSB), a reference signal (e.g., CSI-RS), or a reference signal resource (e.g., CSI-RS resource).

[0549] Optionally, each resource group in the second set is used for interference measurement. In other words, resources in one or more resource groups in the second set, or reference signals (or reference signal resources) are used for interference measurement.

[0550] Optionally, the resources in one or more resource groups in the second set belong to a third serving cell, that is, the resources in one or more resource groups in the second set are resources in the third serving cell.

[0551] Optionally, the first serving cell and the third serving cell are the same serving cell, that is, the first configuration information configures resources in the same cell. In this case, the first serving cell, the second serving cell, and the third serving cell can be the same serving cell. In this way, the configuration information and the resources are in the same serving cell, which can effectively reduce the processing complexity of the system (including the UE), thereby reducing the difficulty of product implementation.

[0552] Optionally, the first serving cell and the third serving cell are different serving cells, that is, the first configuration information configures resources in other cells for the second set. This increases system flexibility, that is, the UE can measure resources (e.g., signal resources) in other cells and then report the measurement results from another cell, thereby improving overall system performance. Optionally, the second serving cell and the third serving cell can be the same serving cell. In this way, the resources for measuring the channel / beam and measuring the interference belong to the same cell, which can better reflect the communication quality.

[0553] For example, when the resource in the second set corresponds to a reference signal resource or a reference signal, the first configuration information may indicate part or all of the following corresponding information (corresponding to the reference signal resource or reference signal information):

[0554] Type of signal / reference signal;

[0555] Signal / reference signal identification or number;

[0556] Resources corresponding to the signal / reference signal (e.g., frequency domain resources, time domain resources, or time-frequency domain resources);

[0557] Power information corresponding to the signal / reference signal;

[0558] Scrambling information corresponding to the signal / reference signal, for example, the scrambling information is used to generate a signal / reference signal sequence;

[0559] QCL information corresponding to the signal / reference signal, or TCI-state information.

[0560] Optionally, in the NR system, each of the one or more resource groups in the second set may indicate one or more CSI-RS resources. Optionally, the resource group may indicate a group of resource CSI-RS resources using a SEQUENCE structure (a structure of RRC signaling).

[0561] Optionally, the first configuration information indicates a first set and a second set. For example, when the first configuration information indicates both the first set and the second set, the terminal device can perform channel measurement based on one or more resource groups in the first set according to the network configuration information, and perform interference measurement based on one or more corresponding resource groups in the second set, and then the terminal device determines the report to the network based on these measurement results (for example, the SINR result or L1-SINR result can be reported). In this way, the UE can directly measure the beam of other interferences, so that the communication quality information can be obtained more accurately, thereby improving the overall performance of the system.

[0562] The following describes the third set:

[0563] Optionally, based on the above, the first configuration information may further indicate a third set, the third set containing one or more resource groups, and the resources in the third set may correspond to a frequency domain resource, or a time domain resource, or a time domain-frequency domain resource.

[0564] For example, the first configuration information for the resources in the third set may indicate part or all of the following corresponding information:

[0565] The resource's identifier, or number;

[0566] Resources corresponding to the signal / reference signal (e.g., frequency domain resources, time domain resources, or time-frequency domain resources), such as the corresponding subcarrier position, the corresponding symbol position, the occupied PRB resources, the period, and the offset.

[0567] Optionally, each resource group in the third set is used for interference measurement. In other words, resources in one or more resource groups in the third set are used for interference measurement.

[0568] Optionally, the resource group in the third set and the corresponding resource group in the first set belong to the same serving cell. In this way, the resources for measuring the channel / beam and measuring the interference belong to the same cell, which can better reflect the communication quality.

[0569] Optionally, the first configuration information indicates the first set and the third set. For example, when the first configuration information indicates the first set and the third set at the same time, the terminal device can perform channel measurement based on one or more resource groups in the first set according to the network configuration information, and perform interference measurement based on the corresponding one or more resource groups in the third set, and then the terminal device determines the report to the network based on these measurement results (for example, the SINR result or L1-SINR result can be reported). In this way, the UE can measure the total interference situation of other cells or other beams, so that the communication quality information can be obtained more accurately, thereby improving the overall performance of the system.

[0570] Optionally, the first configuration information indicates the first set, the second set, and the third set. For example, when the first configuration information indicates the first set, the second set, and the third set at the same time, the terminal device can perform channel measurement based on one or more resource groups in the first set, perform interference measurement based on the corresponding one or more resource groups in the second set, and perform interference measurement based on the corresponding one or more resource groups in the third set according to the network configuration information, and then the terminal device determines the report to the network based on these measurement results (for example, the SINR result or L1-SINR result can be reported). In this way, the UE can directly measure the interference of a characteristic cell or a specific beam, and also measure the overall interference of other cells or other beams, so that the communication quality information can be obtained more accurately and the overall system performance can be improved.

[0571] This concludes the description of the third set.

[0572] Optionally, the first configuration information indicates that the corresponding reporting type is periodic (Periodic), aperiodic (Aperiodic), or semi-persistent (Semi-persistent).

[0573] Optionally, the terminal device may receive multiple first configuration information sent by the network device, where the multiple first configuration information includes one or more of the following: one or more first sets, one or more second sets, and one or more third sets.

[0574] Optionally, the terminal device may receive multiple pieces of first configuration information sent by the network device, where the multiple pieces of first configuration information include one of the following. That is, the network device may configure one of the following for the terminal device:

[0575] Multiple first sets;

[0576] a plurality of first sets and a plurality of second sets;

[0577] Multiple first sets and 1 second set;

[0578] Multiple first sets and multiple third sets (for example, one first configuration information indicates both one first set and one third set, while another first configuration information indicates only one first set. Other situations are similar and can be easily expanded, so they are not listed one by one);

[0579] Multiple first sets and 1 third set;

[0580] a plurality of first sets, a plurality of second sets, and a plurality of third sets;

[0581] a plurality of first sets, a second set, and a plurality of third sets;

[0582] a plurality of first sets, a plurality of second sets, and one third set;

[0583] Multiple first sets, 1 second set, and 1 third set.

[0584] Optionally, the multiple first configuration information can be transmitted in the same RRC signaling. This facilitates sharing of some information, thereby reducing overall signaling overhead. Optionally, the multiple first configuration information are transmitted in different RRC signalings. This simplifies signaling design and provides greater flexibility in network configuration transmission.

[0585] Optionally, the multiple first configuration information are the same configuration information. This allows the same configuration information to indicate more content, facilitating the sharing of partial information and thus reducing overall signaling overhead. Optionally, the multiple first configuration information are different configuration information. This simplifies signaling and protocol design, allowing for greater flexibility when the network sends the corresponding configuration.

[0586] Example 1 (MAC CE Direct Activation)

[0587] On the basis of any one of the embodiments regarding the first configuration information, the terminal device receives the first information sent by the network device, wherein the first information indicates one or more resources (or signal resources, assuming there are L2, L2<=L1) contained in the first resource group (assuming there are L1). For the sake of convenience of description, the indicated one or more resources may be referred to as the first subgroup. In an actual system, this subgroup may be explicitly defined or not (in this application, the term "first subgroup" is used for the sake of convenience of description, referring to the one or more resources indicated by the first information in the first resource group). The first resource group belongs to one of the one or more resource groups in the first set, and the first information is transmitted through the first MAC CE information. In this way, compared with the scheme of configuring the subgroup by RRC, the use of MAC CE to directly indicate and activate some resources can effectively reduce signaling overhead and processing delay.

[0588] Assume that the first set (denoted as G1 for ease of description) indicates X1 resource groups. To simplify the description, we take X1 = 2 as an example. Other values ​​of X1 can be directly expanded and are not described in detail. These two resource groups are denoted as G1_S1 and G1_S2, respectively. G1_S1 contains resources {A1, A2, A3, A4, A5, A6, A7, A8} (for simplicity of description, 8 resources are used as an example. Other numbers can be directly expanded, such as 16 or 32), and G1_S2 contains resources {B1, B2, B3, ...}. X1 can also be 1, in which case only one resource group G1_S1 needs to be considered.

[0589] For example, the first information may indicate one or more resources for resource group G1_S1, for example, indicating resources {A1, A2, A3, A4} (for simplicity of description, a subgroup is taken as 4 resources, and other numbers can be directly expanded, such as 2, 5, 6, 8, etc.). The indicated resources {A1, A2, A3, A4} can be referred to as the first subgroup. In this case, resource group G1_S1 belongs to the first resource group.

[0590] There may be different solutions for specifically indicating which resources the first subgroup includes.

[0591] As an example, indicating which resources the first subgroup contains is done by means of a bitmap to indicate which resources in the first resource group belong to the first subgroup. For example, for the first subgroup of G1_S1, an 8-bit bitmap is used to indicate, where four bits take the value of 1 to indicate resources A1, A2, A3, and A4. Optionally, the 4 bits with a value of 1 can be the first 4 bits (the leftmost 4 bits) or the last 4 bits (the rightmost 4 bits). In this way, compared with the next solution, when the number of resources in the subgroup is relatively large, or when the number of resources in the first resource group is relatively large, the signaling overhead can be reduced.

[0592] Optionally, indicating which resources are included in the first subgroup is performed by indicating one or more numbers to indicate which resources in the first resource group belong to the first subgroup, where the numbers are the numbers of the resources within the first resource group, for example, 0 may correspond to the first resource within the first resource group, and 1 may correspond to the second resource within the first resource group. For example, for the first subgroup of resource group G1_S1, 0, 1, 2, 3 may be directly indicated to correspond to the first, second, third, and fourth resources in resource group G1_S1, i.e., resources A1, A2, A3, and A4, respectively, or 1, 2, 3, 4 may be directly indicated to correspond to the first, second, third, and fourth resources in resource group G1_S1, i.e., resources A1, A2, A3, and A4, respectively. In this way, compared to the previous solution, when the number of resources in a subgroup is relatively small, or when the number of resources in the first resource group is relatively small, signaling overhead can be reduced.

[0593] As an example, indicating which resources are included in the first subgroup is by indicating one or more identifiers to indicate which resources in the first resource group belong to this subgroup, wherein the identifier is an identifier in the resource configuration information. For example, for the first subgroup of G1_S1, the identifiers corresponding to A1, A2, A3, and A4 can be directly indicated, wherein the resources A1, A2, A3, and A4 each contain corresponding identifiers in their respective configuration information. For example, if the resource is a CSI-RS resource (because the CSI-RS resource here is to actually send a CSI-RS signal, it can also be called NZP-CSI-RS-Resource, and NZP refers to non-zero-power), then in the NR system the identifier is nzp-CSI-RS-ResourceId. In this way, directly using the identifier of the CSI-RS resource itself can simplify the UE processing, but the disadvantage is that it may increase the overhead of RRC signaling.

[0594] Optionally, the first information may indicate one or more resources in a plurality of first resource groups. As an example, the first information may also indicate L4 resources among the resources contained in resource group G1_S2, and resource group G1_S2 contains L3 resources, then L4<=L3. At this time, resource group G1_S2 belongs to the first resource group to which it belongs. As another example, the first information may also indicate L5 (1<=L5<=L1) and L6 (1<=L6<=L3) resources among the resources contained in resource group G1_S1 and resource group G1_S2, respectively, at which time resource group G1_S1 and resource group G1_S2 belong to the first resource group.

[0595] Regarding the resource group configuration subgroups that extend to the second and third collections:

[0596] For the resource group configuration subgroups in the second and third sets, you can also follow similar methods as above, so I will not repeat the similar content one by one. For example:

[0597] Based on any of the foregoing, the terminal device receives the second information sent by the network device, and the second information indicates one or more resources (or signal resources) contained in the second resource group. For the convenience of description, the indicated one or more resources can be referred to as the second subgroup. In an actual system, this subgroup can be explicitly defined or not (in this case, the term "second subgroup" is used for the convenience of description, which means that the second information indicates the one or more resources of the second resource group). The second resource group belongs to a resource group among the one or more resource groups in the second set, and the second information is transmitted through the second MAC CE information.

[0598] On the basis of any of the foregoing, the terminal device receives the third information sent by the network device, and the third information indicates one or more resources (or signal resources) contained in the third resource group. For the convenience of description, the indicated one or more resources can be referred to as the third subgroup. In an actual system, this subgroup can be explicitly defined or not (in this case, the term "third subgroup" is used for the convenience of description, which means that the third information indicates the one or more resources of the third resource group). The third resource group belongs to one of the one or more resource groups in the third set, and the third information is transmitted through the third MAC CE information.

[0599] Optionally, the second information and the first information are different indication information. Further, the second MAC CE and the first MAC CE are different MAC CEs. In this way, using different indication information (MAC CEs) makes signaling design more flexible.

[0600] Optionally, the third information and the first information are different indication information. Further, the third MAC CE and the first MAC CE are different MAC CEs. In this way, using different indication information (MAC CEs) makes signaling design more flexible.

[0601] Optionally, the second information and the first information are the same indication information. Further, the second MAC CE and the first MAC CE are the same MAC CE. In this way, using the same indication information (MAC CE) can achieve more optimization in design and reduce the total signaling overhead.

[0602] Optionally, the third information and the first information are the same indication information. Further, the third MAC CE and the first MAC CE are the same MAC CE. In this way, using the same indication information (MAC CE) can achieve more optimization in design and reduce the total signaling overhead.

[0603] Optionally, the second information, the third information, and the first information are the same indication information. Further, the second MAC CE, the third MAC CE, and the first MAC CE are the same MAC CE. In this way, using the same indication information (MAC CE) can achieve more optimization in design and reduce the overall signaling overhead.

[0604] The following describes various embodiments using the first MAC CE as an example. If the second MAC CE and / or third MAC CE are different from the first MAC CE, the following embodiments can be directly extended to the second and third MAC CEs. Because the specific details are similar, they will not be detailed here.

[0605] Optionally, the first MAC CE indicates a first serving cell (or carrier), and the first information applies to the first serving cell (indicates the Serving Cell for which the MAC CE applies). As an example, the first MAC CE may indicate the first serving cell by using a serving cell ID (Serving Cell ID).

[0606] Optionally, the first MAC CE indicates a first BWP, and the first information applies to the first BWP (indicates the BWP for which the MAC CE applies). As an example, the first MAC CE may indicate the first BWP through a BWP ID.

[0607] Optionally, the first MAC CE indicates a second serving cell (or carrier), and the resources (or signal resources) of the first subgroup are in the second serving cell (or belong to the second serving cell). In this way, the signals and / or resources measured in other cells can be flexibly indicated. As an example, the first MAC CE can indicate the second serving cell by using a serving cell ID (Serving Cell ID). As an example, if the first MAC CE also indicates a second subgroup, the resources (or signal resources) within the second subgroup are in the second serving cell. As an example, if the first MAC CE also indicates a third subgroup, the resources within the third subgroup are in the second serving cell.

[0608] Optionally, the first MAC CE does not indicate a second serving cell (or carrier), and the resources (or signal resources) within the first subgroup are in (or belong to) the first serving cell. This reduces signaling overhead. Compared with the above solution, the cost is that the measured signals of other cells / carriers cannot be indicated. As an example, if the first MAC CE also indicates a second subgroup, the resources (or signal resources) within the second subgroup are in the first serving cell. As an example, if the first MAC CE also indicates a third subgroup, the resources within the third subgroup are in the first serving cell.

[0609] Optionally, the first MAC CE indicates a second BWP, and the resources (or signal resources) within the first subgroup are within (or belong to) the second BWP. This allows for flexible indication of the signals and / or resources measured in other BWPs. As an example, the first MAC CE may indicate the second BWP using a BWP ID. As an example, if the first MAC CE also indicates a second subgroup, the resources (or signal resources) within the second subgroup are within the second BWP. As an example, if the first MAC CE also indicates a third subgroup, the resources within the third subgroup are within the second BWP.

[0610] Optionally, the first MAC CE does not indicate the second BWP, and the resources (or signal resources) within the first subgroup are within (or belong to) the first BWP. This reduces signaling overhead. Compared to the above solution, the trade-off is that the measured signals of other BWPs cannot be indicated. As an example, if the first MAC CE also indicates the second subgroup, the resources (or signal resources) within the second subgroup are within the first BWP. As an example, if the first MAC CE also indicates the third subgroup, the resources within the third subgroup are within the first BWP.

[0611] Optionally, the first information indicates a first reporting configuration. As an example, the first reporting configuration indicates a first set, or the first reporting configuration indicates a first resource group, so that the indication of information such as the serving cell and BWP of the first resource group can be reduced, thereby reducing signaling overhead.

[0612] Taking the 5G / NR system as an example (it can also be used in other systems. Other places are similar and will not be repeated here), the first reporting configuration can be a channel state information reporting configuration (CSI-ReportConfig). Optionally, the first information indicates a CSI-ReportConfig. Optionally, the first information can indicate an ID of a channel state information reporting configuration to indicate the channel state information reporting configuration. For example, the ID of the channel state information reporting configuration can be CSI-ReportConfigId or reportConfigId.

[0613] When the first information indicates the first reporting configuration, the first information may no longer indicate the second serving cell or the second BWP, wherein the serving cell / BWP where the first subgroup is located may be determined according to the first reporting configuration.

[0614] Optionally, the first information indicates a first aperiodic activation state. As an example, the first aperiodic activation state indicates a first set, or the first aperiodic activation state indicates a first resource group. In this way, the indication of information such as a serving cell and a BWP of the first resource group can be reduced, thereby reducing signaling overhead.

[0615] Taking the 5G / NR system as an example, the first non-periodic activation state can be a channel state information non-periodic trigger state. Optionally, the channel state information non-periodic trigger state (CSI-AperiodicTriggerState) can be CSI-AperiodicTriggerState. Optionally, the first information can indicate a number to indicate the channel state information non-periodic trigger state. For example, if the number is 0, it corresponds to the first CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, the number is 1, it corresponds to the second CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, and so on. For another example, if the number is 1, it corresponds to the first CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, the number is 2, it corresponds to the second CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, and so on, and so on.

[0616] When the first information indicates the first aperiodic activation state, the first information may no longer indicate the second serving cell or the second BWP. The serving cell and BWP of the first subgroup may be determined according to the first reporting configuration.

[0617] The following describes the MAC CE using the first MAC CE as an example. It should be noted that the description of the second MAC CE and the third MAC CE is similar to that of the first MAC CE, and this application will not go into details therein.

[0618] MAC CE Example 1

[0619] As an example, the first MAC CE includes one or more of the following information (the order is not limited, and the position of the information in other embodiments may also be changed. It is not limited and is only used as an example. In addition, some of the information listed may not be required. The subsequent other parts are similar and will not be repeated one by one):

[0620] Serving cell indication information, used to indicate the first serving cell;

[0621] Resource group indication information, used to indicate the first resource group;

[0622] The resource indication information is used to indicate one or more resources in the first resource group (ie, the first subgroup).

[0623] Optionally, the resource indication information may be indicated in a bitmap manner, wherein when the bit value is 1, it indicates that the corresponding resource in the first resource group is indicated or activated. Optionally, the resource indication information may indicate or activate the corresponding resource in the first resource group by indicating the number or identifier of one or more resource groups.

[0624] The first resource group is in a first serving cell, and the first MAC CE is applied to the first serving cell.

[0625] MAC CE Example 2

[0626] As an example, the first MAC CE includes one or more of the following information:

[0627] Serving cell indication information, used to indicate the first serving cell;

[0628] Reporting configuration indication information, used to indicate the first reporting configuration;

[0629] Resource group indication information, used to indicate the first resource group;

[0630] The resource indication information is used to indicate one or more resources in the first resource group (ie, the first subgroup).

[0631] Optionally, the resource indication information may be indicated in a bitmap manner, wherein when the bit value is 1, it indicates that the corresponding resource in the first resource group is indicated or activated. Optionally, the resource indication information may indicate or activate the corresponding resource in the first resource group by indicating the number or identifier of one or more resource groups.

[0632] The first MAC CE is applied to the first serving cell. The serving cell corresponding to the first resource group is indicated by the first reporting configuration.

[0633] As an example, the above "resource group indication information" does not need to be included in the first MAC CE. In this case, the "resource indication information" is applied to all resource groups indicated by the first reporting configuration.

[0634] Take 5G / NR as an example:

[0635] If the first reporting configuration indicates the resource group resourcesForChannelMeasurement (resources used for channel measurement), the "resource indication information" applies to the resource group resourcesForChannelMeasurement.

[0636] If the first reporting configuration indicates the resource group resourcesForChannelMeasurement and nzp-CSI-RS-ResourcesForInterference (NZP-CSI-RS-Resource for interference), the "resource indication information" applies to the resource group resourcesForChannelMeasurement and nzp-CSI-RS-ResourcesForInterference.

[0637] If the first reporting configuration indicates the resource group resourcesForChannelMeasurement and csi-IM-ResourcesForInterference (csi-IM-Resources for interference), the "resource indication information" applies to the resource group resourcesForChannelMeasurement and csi-IM-ResourcesForInterference.

[0638] If the first reporting configuration indicates the resource groups resourcesForChannelMeasurement, csi-IM-ResourcesForInterference, and nzp-CSI-RS-ResourcesForInterference, the "resource indication information" applies to the resource groups resourcesForChannelMeasurement, csi-IM-ResourcesForInterference, and nzp-CSI-RS-ResourcesForInterference.

[0639] In the above example, if resourcesForChannelMeasurement (or csi-IM-ResourcesForInterference or nzp-CSI-RS-ResourcesForInterference) itself contains multiple resource groups, then the "resource indication information" applies to the multiple resource groups it contains, or to a specific resource group it contains (the specific resource group is originally specified in the protocol or determined according to the network configuration).

[0640] An extension of MAC CE Example 2 is that the MAC CE may indicate multiple reporting configuration indication information, where:

[0641] Option 1: Multiple “reporting configuration indication information” correspond to the same “resource indication information” (Example 2A).

[0642] Option 2: Multiple "reporting configuration indication information" each corresponds to one "resource indication information" (Example 2B).

[0643] The following two examples are used as examples. At the same time, the main information is listed, and some information similar to other examples is not listed one by one.

[0644] MAC CE Example 2A

[0645] As an example, the first MAC CE includes one or more of the following information:

[0646] Serving cell indication information, used to indicate the first serving cell;

[0647] Report configuration indication information 1, used to indicate a report configuration;

[0648] Report configuration indication information 2, used to indicate another reporting configuration;

[0649] The resource indication information is used to indicate one or more resources in the first resource group.

[0650] Optionally, the resource indication information may be indicated in a bitmap manner, wherein when the bit value is 1, it indicates that the corresponding resource in the first resource group is indicated or activated. Optionally, the resource indication information may indicate or activate the corresponding resource in the first resource group by indicating the number or identifier of one or more resource groups.

[0651] MAC CE Example 2B

[0652] As an example, the first MAC CE includes one or more of the following information:

[0653] Serving cell indication information, used to indicate the first serving cell;

[0654] Report configuration indication information 1, used to indicate a report configuration;

[0655] Report configuration indication information 2, used to indicate another reporting configuration;

[0656] Resource indication information 1, used to indicate one or more resources in the resource group;

[0657] Resource indication information 2 is used to indicate one or more resources in the resource group.

[0658] MAC CE Example 3

[0659] As an example, the first MAC CE includes one or more of the following information:

[0660] Serving cell indication information, used to indicate the first serving cell;

[0661] Aperiodic activation state indication information, used to indicate a first aperiodic activation state;

[0662] Resource group indication information, used to indicate the first resource group;

[0663] The resource indication information is used to indicate one or more resources in the first resource group (ie, the first subgroup).

[0664] Optionally, the resource indication information may be indicated in a bitmap manner, wherein when the bit value is 1, it indicates that the corresponding resource in the first resource group is indicated or activated. Optionally, the resource indication information may indicate or activate the corresponding resource in the first resource group by indicating the number or identifier of one or more resource groups.

[0665] The first MAC CE is applied to the first serving cell. The serving cell corresponding to the first resource group is indicated by a first aperiodic activation state.

[0666] As an example, the above “resource group indication information” does not need to be included in the first MAC CE. In this case, the “resource indication information” is applied to all resource groups indicated by the first aperiodic activation state.

[0667] Take 5G / NR as an example:

[0668] If the first non-periodic activation state indicates the resource group resourcesForChannel, the “resource indication information” applies to the resource group resourcesForChannel.

[0669] If the first non-periodic activation state indicates the resource group resourcesForChannel and csi-IM-ResourcesForInterference, the “resource indication information” applies to the resource group resourcesForChannel and csi-IM-ResourcesForInterference.

[0670] If the first non-periodic activation state indicates the resource group resourcesForChannel and csi-IM-ResourcesForInterference, the “resource indication information” applies to the resource group resourcesForChannel and csi-IM-ResourcesForInterference.

[0671] If the first non-periodic activation state indicates the resource groups resourcesForChannel, csi-IM-ResourcesForInterference, and nzp-CSI-RS-ResourcesForInterference, the “resource indication information” applies to the resource groups resourcesForChannel, csi-IM-ResourcesForInterference, and nzp-CSI-RS-ResourcesForInterference.

[0672] In the above example, if resourcesForChannel (or csi-IM-ResourcesForInterference, or nzp-CSI-RS-ResourcesForInterference) itself contains multiple resource groups, then the "resource indication information" applies to the multiple resource groups it contains, or to a specific resource group it contains (the specific resource group is determined according to the original protocol requirements or the network configuration).

[0673] An extension of MAC CE Example 3 is that the MAC CE may indicate multiple reporting aperiodic activation status indication information, where:

[0674] Option 1: multiple "aperiodic activation state indication information" correspond to the same "resource indication information" (Example 3A).

[0675] Option 2: Each of the multiple "aperiodic activation status indication information" corresponds to one "resource indication information" (Example 3B).

[0719] Option 1: The first resource group is in the second serving cell.

[0720] Option 2: The first resource group is in the first BWP in the second serving cell.

[0721] MAC CE Example 7

[0722] As an example, the first MAC CE includes one or more of the following information:

[0723] Serving cell indication information 1, used to indicate the first serving cell;

[0724] BWP indication information 1, used to indicate a first BWP (or a first downlink BWP, a first DL BWP);

[0725] Serving cell indication information 2, used to indicate a second serving cell;

[0726] BWP indication information 2 is used to indicate a second BWP (or a second downlink BWP, a second DL BWP);

[0727] Resource group indication information, used to indicate the first resource group;

[0728] The resource indication information is used to indicate one or more resources corresponding to the first resource group (ie, the first subgroup).

[0729] The first MAC CE is applied to the first BWP of the first serving cell and the second BWP of the second serving cell in the first resource group.

[0730] Optionally, in each of the foregoing MAC CE examples, the resource indication information may indicate one or more resources in the following manner:

[0731] Indicate resources through bitmap;

[0732] Indicating a resource by indicating one or more numbers, wherein the numbers belong to numbers of the resource within a first resource group;

[0733] The resource is indicated by indicating one or more identifiers. For example, if the resource is a CSI-RS resource (because the CSI-RS resource here is to actually transmit the CSI-RS signal, it can also be called NZP-CSI-RS-Resource, where NZP stands for non-zero-power), then the identifier in the NR system is nzp-CSI-RS-ResourceId.

[0734] Based on any of the foregoing, optionally, if the measurement and / or reporting of the terminal device (or a certain measurement and / or reporting, which are similar and will not be elaborated on one by one) corresponds to the first resource group (for example, the configuration corresponding to the current measurement and / or reporting indicates the first resource group), the terminal device performs measurement and / or reporting based on the first subgroup.

[0735] Optionally, if the first configuration information indicates a second set and the second subgroup is also indicated by the network, the terminal device also needs to perform measurements and / or reports based on the second subgroup (that is, based on the first subgroup, the following several places are similar). In this way, by measuring the interference, the system can be assisted in making a better selection of the beam.

[0736] Optionally, if the first configuration information indicates a third set and the third subgroup is also indicated by the network, the terminal device also needs to perform measurements and / or reports based on the third subgroup. In this way, the interference can be measured to assist the system in making a better selection of the beam.

[0737] Optionally, if the first configuration information indicates a second set, but the network does not indicate a second subgroup, the terminal device also performs measurements and / or reports based on the second subgroup. The second subgroup is determined according to a second predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the subgroup of the first resource group and the subgroup of the second resource group configured by the network (for example, the network indicates the correspondence through RRC parameters), or the second subgroup is the second resource group, thereby reducing signaling overhead.

[0738] Optionally, if the first configuration information indicates a third set, but the network does not indicate a third subgroup, the terminal device also performs measurements and / or reports based on the third subgroup. The third subgroup is determined according to a second predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the subgroup of the first resource group and the subgroup of the third resource group configured by the network (for example, the network indicates the correspondence through RRC parameters), or the third subgroup is the third resource group, thereby reducing signaling overhead.

[0739] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group (for example, the first resource group is indicated in the configuration corresponding to the current measurement and / or reporting), and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group (that is, based on the first resource group itself, not its subgroup). In this way, defining the default behavior when the UE does not receive the first information can reduce additional signaling design.

[0740] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group and the second resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group and the second resource group.

[0741] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group and the third resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group and the third resource group.

[0742] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group, the second resource group and the third resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group, the second resource group and the third resource group.

[0743] The following description is about UE reporting. It should be noted that although the content of UE reporting is described in this embodiment, the following content about UE reporting can be applied to other embodiments and will not be repeated in other embodiments.

[0744] About UE reporting:

[0745] Optionally, the above solution is applicable to aperiodic (AP) reporting, which offers the highest flexibility. Adding flexible subgroup-based indications to this approach further enhances system flexibility. By omitting periodic and semi-continuous reporting, network and terminal implementation complexity can be reduced.

[0746] Optionally, the above solution is applicable to periodic (P) reporting. Periodic reporting is relatively inflexible, so introducing flexible subgroup-based indications can improve system flexibility. By not using aperiodic and semi-continuous reporting, network and terminal implementation complexity can be reduced.

[0747] Optionally, the above solution is applicable to semi-persistent (SP) reporting. Compared with aperiodic reporting, semi-persistent reporting is relatively less flexible. Introducing flexible subgroup-based indication can improve system flexibility. Meanwhile, by not using aperiodic and periodic reporting, network and terminal implementation complexity can be reduced.

[0748] Optionally, the above solution is applicable to aperiodic (AP) reporting, periodic (P) reporting and semi-persistent (SP) reporting. In this way, flexible indication based on subgroups is introduced into all reporting modes, which can improve system flexibility.

[0749] Optionally, the above solution is applicable to periodic (P) reporting and semi-persistent (SP) reporting. Compared with aperiodic reporting, periodic and semi-persistent reporting are relatively less flexible. Introducing flexible subgroup-based indications can improve system flexibility. At the same time, not using aperiodic reporting can reduce network and terminal implementation complexity.

[0750] Optionally, the terminal device reports the first result to the network device. Optionally, the first result may include the following options:

[0751] Option 1: The first result includes a measurement result. For example, it includes the measured L1-RSRP, and / or a corresponding signal identifier or signal resource identifier (for example, one identifier indicates a CSI-RS resource, and for another example, the identifier indicates an SSB). For example, the first result may include K L1-RSRP measurement results. For another example, the first result may include K pairs, each pair having a signal indication information / identifier (for example, SSB indication information / identifier, or CSI-RS resource indication information / identifier) ​​and a corresponding measured L1-RSRP. As an example, the first result contains 4 pairs (it can also be 1 pair, 2 pairs, 3 pairs, 5 pairs, 6 pairs, 8 pairs, etc., and no longer listed one by one. Other values ​​are also possible, such as 7, 9, 10, 16, etc. The other examples are the same): {CSI-RS resource indicator1, L1-RSRP1}, {CSI-RS resource indicator2, L1-RSRP2}, {CSI-RS resource indicator3, L1-RSRP3}, {CSI-RS resource indicator4, L1-RSRP4}.

[0752] In one example, the first result includes four measurement results: L1-RSRP1, L1-RSRP2, L1-RSRP3, and L1-RSRP4. The positions of these four measurement results in the first result are determined according to a predetermined rule (for example, the corresponding CSI-RS resource indicator with a smaller value is placed first, or the corresponding CSI-RS resource indicator with a larger value is placed first).

[0753] In this way, the terminal performs measurements based on one or more subgroups and reports the measurement results to the network. The network can then determine subsequent beam management operations based on appropriate algorithms or rules (such as deep learning algorithms, AI algorithms, machine learning algorithms, statistical algorithms, etc., the specific algorithms are not limited). For example, the network can ask the UE to perform beam measurements, configure some beams for the UE, or instruct the UE to use one or more beams for transmission. This improves overall network performance.

[0754] Option 2: The first result includes the prediction result of the terminal device, for example, the signal (or signal resource) predicted by the terminal device. Optionally, the predicted signal / signal resource can be reported by an identifier (for convenience of representation, it is referred to as a predicted identifier) ​​(for example, a predicted identifier indicates a predicted CSI-RS resource, and for another example, the identifier indicates a predicted SSB). Optionally, the first result may also include an RSRP value (or L1-RSRP value) predicted by the terminal device, where the predicted RSRP value corresponds to the predicted signal or signal resource.

[0755] For example, the first result may include K predicted signals or signal resources (for example, indicated by SSB indication information / identifier, or CSI-RS resource indication information / identifier). For another example, the first result may include K pairs, where each pair has a signal indication information / identifier (for example, SSB indication information / identifier, or CSI-RS resource indication information / identifier) ​​and a corresponding predicted L1-RSRP. As an example, the first result contains 4 pairs: {CSI-RS resource indicator1, L1-RSRP1}, {CSI-RS resource indicator2, L1-RSRP2}, {CSI-RS resource indicator3, L1-RSRP3}, {CSI-RS resource indicator4, L1-RSRP4}.

[0756] As an example, the first result contains 4 pairs (indicating both SSB and CSI-RS resource): {CSI-RS resource indicator1, L1-RSRP1}, {SSB index2, L1-RSRP2}, {CSI-RS resource indicator3, L1-RSRP3}, {CSI-RS resource indicator4, L1-RSRP4}.

[0757] In this way, the terminal performs measurements based on one or more subgroups, and then uses appropriate algorithms or rules (such as deep learning algorithms, AI algorithms, machine learning algorithms, statistical algorithms, etc., the specific algorithms are not limited) to determine which beams are most beneficial to itself. Reporting these predicted beams to the network can assist the network in making better beam management and improving network performance.

[0758] Option 3: This is a combination of Option 2 and Option 1. The first result includes both the measured L1-RSRP and the predicted L1-RSRP.

[0759] Optionally, the first result may include additional information, where the additional information is used to indicate whether a certain L1-RSRP is a measurement result or a prediction result.

[0760] In one example, the first result contains 4 pairs: {CSI-RS resource indicator1, L1-RSRP1, flag1}, {CSI-RS resource indicator2, L1-RSRP2, flag2}, {CSI-RS resource indicator3, L1-RSRP3, flag3}, {CSI-RS resource indicator4, L1-RSRP4, flag4}.

[0761] As an example, the first result contains 4 pairs (indicating both SSB and CSI-RS resource): {CSI-RS resource indicator1, L1-RSRP1, flag1}, {SSB index2, L1-RSRP2, flag2}, {CSI-RS resource indicator3, L1-RSRP3, flag3}, {CSI-RS resource indicator4, L1-RSRP4, flag4}.

[0762] Among them, the first value of flag1, flag2, flag3, and flag4 above indicates the measured L1-RSRP, and the second value indicates the predicted L1-RSRP.

[0763] Optionally, a third predetermined rule (which may be implemented in a protocol or in a network configuration) is used, such as the position of the reported information, to indicate whether a particular L1-RSRP is a measurement result or a prediction result. In this way, in some cases, the L1-RSRP measured by the UE itself may be more accurate than the prediction. Reporting the measured L1-RSRP to the network can help the network perform better beam management and improve network performance.

[0764] Optionally, in the first result, a signal or signal resource may have a corresponding measured L1-RSRP and a predicted L1-RSRP. As an example, the first result includes both a measured L1-RSRP and a predicted L1-RSRP corresponding to a certain CSI-RS resource. For example, the first result includes {CSI-RS resource indicator1, L1-RSRP 1A, L1-RSRP 1B}. There are also different ways to distinguish whether the result is measured or predicted. For example, the measured L1-RSRP is placed before the predicted L1-RSRP, and for another example, the predicted L1-RSRP is placed before the measured L1-RSRP. For example, each L1-RSPR corresponds to an additional information to indicate whether it is measured or predicted. In this way, reporting more information to the network can assist the network in making better beam management and improving network performance.

[0765] Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, the reported first result includes the measured L1-RSRP corresponding to the signal or signal resource. As an example, if a certain CSI-RS resource has both a corresponding measured L1-RSRP and a corresponding predicted L1-RSRP, the first result only includes the measured L1-RSRP corresponding to the certain CSI-RS resource. In this way, in some cases, the L1-RSRP measured by the UE itself may be more accurate than the predicted one. Reporting the measured L1-RSRP to the network can assist the network in making better beam management and improving network performance.

[0766] Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, the reported first result includes the predicted L1-RSRP corresponding to the signal or signal resource. As an example, if a certain CSI-RS resource has both a corresponding measured L1-RSRP and a corresponding predicted L1-RSRP, the first result only includes the predicted L1-RSRP corresponding to the certain CSI-RS resource. In this way, the UE reports the predicted L1-RSRP corresponding to this signal resource, which can facilitate the network to better compare the quality of different beams (reference resources) because they are all predicted, thereby facilitating the network to make better beam management and improve network performance.

[0767] Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, it is determined based on third information whether the reported first result includes the measured L1-RSRP corresponding to the signal or signal resource, or the predicted L1-RSRP corresponding to the signal or signal resource. The third information is sent by the network device to the terminal device. In this way, the network uses signaling to clarify whether the UE reports the predicted L1-RSRP or the measured L1-RSRP, thereby providing the network with greater freedom.

[0768] As an example, it can be determined based on the value of the third information. For example, when the third information is the first value, the first result includes the measured L1-RSRP corresponding to the signal or signal resource. When the third information is the second value, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource.

[0769] As an example, determining based on the third information can be based on whether the network has sent or configured the third information. For example, when the network does not send or indicate the third information, the first result includes the measured L1-RSRP corresponding to the signal or signal resource. When the network sends or indicates the third information, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource. For another example, when the network does not send or indicate the third information, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource. When the network sends or indicates the third information, the first result includes the measured L1-RSRP corresponding to the signal or signal resource. In this way, signaling overhead can be reduced.

[0770] The above example uses L1-RSRP. In other embodiments, L1-RSRP can also be replaced by L1-SINR. The solution can be directly expanded and will not be described in detail.

[0771] In addition, in the above report, L1-RSRP may be quantized (for example, it may be quantized according to a quantization method fixed by the protocol or a quantization method configured by the network), and the quantized result is reported.

[0772] Optionally, in the above reporting, if the first result includes multiple L1-RSRPs (which may be measured or predicted), a differential manner may be used for reporting, thereby reducing reporting overhead.

[0773] The terminal can select an appropriate algorithm or rule (such as a deep learning algorithm, an AI algorithm, a machine learning algorithm, a statistical algorithm, etc., the specific algorithm is not limited) to predict the corresponding beam, or predict the corresponding resources (such as CSI-RS resource, SSB, etc.), and can also predict the corresponding L1-RSRP or the corresponding L1-SINR.

[0774] Example 2 (MAC configuration of multiple subsets + DCI indication)

[0775] Based on any one of the embodiments regarding the first configuration information, the MAC CE configures one or more subsets. Optionally, the terminal device receives fourth information sent by the network device, wherein the fourth information indicates one or more subsets for the first resource group, wherein the first resource group belongs to one of the one or more resource groups in the first set, and resources (or signal resources) contained in each of the one or more subsets belong to resources in the first resource group, and the fourth information is transmitted via a fourth MAC CE information. In this way, compared with the solution of configuring the subsets by RRC, using the MAC CE to directly indicate the one or more subsets can effectively reduce signaling overhead and processing delay.

[0776] Optionally, for a subgroup in the one or more subgroups, the fourth information indicates a corresponding subgroup identifier, so that subsequent DCI signaling is convenient for indicating the corresponding subgroup.

[0777] Assume that the first set (denoted as G1 for ease of description) indicates X1 resource groups. To simplify the description, we use X1 = 2 as an example. Other values ​​of X1 can be directly expanded and are not described in detail. These two resource groups are denoted as G1_S1 and G1_S2, respectively. G1_S1 contains resources {A1, A2, A3, A4, A5, A6, A7, A8} (for simplicity, 8 resources are used as an example. Other numbers can be directly expanded, such as 16 or 32), and G1_S2 contains resources {B1, B2, B3, ...}. X1 can also be 1, in which case only one resource group G1_S1 needs to be considered.

[0778] For example, the fourth information may indicate two subgroups for resource group G1_S1. For example, it may indicate that the first subgroup subset1 includes resources {A1, A2, A3, A4} (for simplicity of description, a subgroup is taken as an example with 4 resources. Other numbers can be directly expanded, such as 2, 5, 6, 8, etc.), and at the same time indicate the second subgroup subset2, including resources {A3, A4, A5, A6} or resources {A5, A6, A7, A8}. In this case, resource group G1_S1 belongs to the first resource group. The fourth information may also indicate only one subgroup (for example, subset1).

[0779] For another example, the fourth information may further indicate a number or identifier for the first subset 1 and a number or identifier for the second subset 2.

[0780] Optionally, each of the one or more subgroups indicates which resources in the first resource group belong to this subgroup by means of a bitmap. For example, for the first subgroup subset1 of G1_S1, an 8-bit bitmap is used for indication, wherein four bits take the value of 1 to indicate resources A1, A2, A3, and A4. Optionally, the 4 bits with a value of 1 can be the first 4 bits (the leftmost 4 bits) or the last 4 bits (the rightmost 4 bits). In this way, compared with the next solution, when the number of resources in the subgroup is relatively large, or when the number of resources in the first resource group is relatively large, the signaling overhead can be reduced.

[0781] Optionally, each of the one or more subgroups indicates which resources in the first resource group belong to this subgroup by indicating one or more numbers, where the numbers are the numbers of the resources in the first resource group, for example, 0 can correspond to the first resource in the first resource group, and 1 can correspond to the second resource in the first resource group. In this way, compared with the previous scheme, when the number of resources in the subgroup is relatively small, or when the number of resources in the first resource group is relatively small, the signaling overhead can be reduced.

[0782] Optionally, each of the one or more subgroups indicates which resources in the first resource group belong to this subgroup by indicating one or more identifiers, wherein the identifier is an identifier in the resource configuration information. For example, if the resource is a CSI-RS resource (because the CSI-RS resource here is to actually send a CSI-RS signal, it can also be called NZP-CSI-RS-Resource, NZP refers to non-zero-power), then in the NR system the identifier is nzp-CSI-RS-ResourceId. In this way, directly using the identifier of the CSI-RS resource itself can simplify the UE processing. The disadvantage is that it may increase the overhead of RRC signaling.

[0783] Optionally, the fourth information may indicate subgroups corresponding to multiple first resource groups.

[0784] Regarding the resource group configuration subgroups that extend to the second and third collections:

[0785] For the resource group configuration subgroups in the second and third sets, you can also follow similar methods as above, so I will not repeat the similar content one by one. For example:

[0786] Optionally, the fifth information indication may be used to indicate one or more subgroups for the second resource group, where the second resource group belongs to one resource group among the one or more resource groups in the second set, and the resources (or signal resources) contained in each of the one or more subgroups belong to the resources in the second signal group.

[0787] Optionally, the sixth information indication may be used to indicate one or more subgroups for the third resource group, wherein the third resource group belongs to one resource group among the one or more resource groups in the third set, and the resources contained in each of the one or more subgroups belong to the resources in the third resource group (note: not signal resources).

[0788] Optionally, the fourth information and the fifth information are the same information.

[0789] Optionally, the fourth information and the sixth information are the same information.

[0790] Optionally, the fourth information, the fifth information and the sixth information are the same information.

[0791] Optionally, the fourth information indicates a first serving cell (or carrier), and the first information applies to the first serving cell (indicates the Serving Cell for which the MAC CE applies). As an example, the first serving cell is indicated by a serving cell ID (Serving Cell ID).

[0792] Optionally, the fourth information indicates a first BWP, and the fourth information applies to the first BWP (indicates the BWP for which the MAC CE applies). As an example, the first BWP is indicated by a BWP ID.

[0793] Optionally, the fourth information indicates a second serving cell (or carrier), and the resources (or signal resources) of one or more subgroups of the first resource group are in the second serving cell (or belong to the second serving cell). In this way, the signals and / or resources measured in other cells can be flexibly indicated. Exemplarily, the second serving cell is indicated by a serving cell ID (Serving Cell ID). Optionally, if the fourth information also indicates one or more subgroups of the second resource group, the resources (or signal resources) of the one or more subgroups of the second resource group are in the second serving cell. Optionally, if the fourth information also indicates one or more subgroups of the third resource group, the resources of the one or more subgroups of the second resource group are in the second serving cell.

[0794] Optionally, if the second serving cell is not indicated, the resources (or signal resources) of one or more subgroups of the first resource group are in the first serving cell, which can reduce signaling overhead. Compared with the above solution, the cost is that the measured signals of other cells / carriers cannot be indicated. Optionally, if the fourth information also indicates one or more subgroups of the second resource group, the resources (or signal resources) of the one or more subgroups of the second resource group are in the first serving cell. Optionally, if the fourth information also indicates one or more subgroups of the third resource group, the resources of the one or more subgroups of the second resource group are in the first serving cell.

[0795] Optionally, the fourth information indicates a second BWP, and the resources (or signal resources) of one or more subgroups of the first resource group are within (or belong to) the second BWP. This allows for flexible indication of the signals and / or resources being measured in other BWPs. As an example, the second BWP is indicated by a BWP ID. Optionally, if the fourth information also indicates one or more subgroups of the second resource group, the resources (or signal resources) of the one or more subgroups of the second resource group are within the second BWP. Optionally, if the fourth information also indicates one or more subgroups of the third resource group, the resources of the one or more subgroups of the third resource group are within the second BWP.

[0796] Optionally, if the fourth information does not indicate a second BWP, the resources (or signal resources) of one or more subgroups of the first resource group are within the first BWP. This reduces signaling overhead. Compared to the above solution, the trade-off is that the measured signals of other BWPs cannot be indicated. Optionally, if the fourth information also indicates one or more subgroups of the second resource group, the resource signals (or signal resources) of the one or more subgroups of the second resource group are within the first BWP. Optionally, if the fourth information also indicates one or more subgroups of the third resource group, the resources of the one or more subgroups of the third resource group are within the first BWP.

[0797] Optionally, the first information indicates a first reporting configuration. As an example, the first reporting configuration indicates a first set, or the first reporting configuration indicates a first resource group, so that the indication of information such as the serving cell and BWP of the first resource group can be reduced, thereby reducing signaling overhead.

[0798] Taking the 5G / NR system as an example (it can also be used in other systems. Other places are similar and will not be repeated here), the first reporting configuration can be a channel state information reporting configuration. Optionally, the first information indicates a CSI-ReportConfig. Optionally, the first information can indicate an ID of a channel state information reporting configuration to indicate the channel state information reporting configuration. For example, the ID of the channel state information reporting configuration can be CSI-ReportConfigId or reportConfigId.

[0799] When the first information indicates the first reporting configuration, the first information may no longer indicate the second serving cell or the second BWP, wherein the serving cell / BWP where the first subgroup is located may be determined according to the first reporting configuration.

[0800] Optionally, the first information indicates a first aperiodic activation state. As an example, the first aperiodic activation state indicates a first set, or the first aperiodic activation state indicates a first resource group. In this way, the indication of information such as a serving cell and a BWP of the first resource group can be reduced, thereby reducing signaling overhead.

[0801] Taking the 5G / NR system as an example, the first non-periodic activation state can be a channel state information non-periodic trigger state. Optionally, the channel state information non-periodic trigger state can be CSI-AperiodicTriggerState. Optionally, the first information can indicate a number to indicate the channel state information non-periodic trigger state. For example, if the number is 0, it corresponds to the first CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, the number is 1, it corresponds to the second CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, and so on. For another example, if the number is 1, it corresponds to the first CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, the number is 2, it corresponds to the second CSI-AperiodicTriggerState in the CSI-AperiodicTriggerStateList, and so on.

[0802] When the first information indicates the first aperiodic activation state, the first information may no longer indicate the second serving cell or the second BWP. The serving cell and BWP of the first subgroup may be determined according to the first reporting configuration.

[0803] Optionally, for the relevant description on UE reporting in this embodiment, please refer to the relevant description on UE reporting in Example 1, which is not described in detail in this embodiment.

[0804] This embodiment provides a MAC CE example.

[0805] The MAC CE examples in this embodiment can be directly expanded upon MAC CE examples 1-7 in the previous embodiment 1. In this embodiment, the "resource indication information" in MAC CE examples 1-7 is replaced with "subgroup indication information." The subgroup indication information may indicate one or more subgroups, where each subgroup indicates one or more resources in one or more of the following ways:

[0806] Indicate resources through bitmap;

[0807] Indicating a resource by indicating one or more numbers, wherein the numbers belong to numbers of the resource within a first resource group;

[0808] The resource is indicated by indicating one or more identifiers. For example, if the resource is a CSI-RS resource (because the CSI-RS resource here is to actually transmit the CSI-RS signal, it can also be called NZP-CSI-RS-Resource, where NZP stands for non-zero-power), then the identifier in the NR system is nzp-CSI-RS-ResourceId.

[0809] In addition, the MAC CE optionally further indicates the subgroup identifier or number corresponding to each subgroup. If the MAC CE does not indicate the subgroup identifier or number, the corresponding number can be determined according to the order in which they appear in the MAC CE signaling, for example, 0 corresponds to the first subgroup, 1 corresponds to the second subgroup, and so on. For another example, 1 corresponds to the first subgroup, 2 corresponds to the second subgroup, and so on.

[0810] Optionally, if the fourth information indicates only one subgroup for the first resource group, the one subgroup is the first subgroup. In this way, when there is one subgroup, no DCI indication is required, thereby saving DCI signaling overhead.

[0811] Optionally, the terminal device receives seventh information sent by the network device, where the seventh information indicates a first subgroup corresponding to the first resource group, where the first subgroup belongs to a subgroup of one or more subgroups corresponding to the first resource group (i.e., the one or more subgroups indicated by the first MAC CE), and the seventh information is indicated by the first DCI signaling. In this way, the DCI signaling processing delay is reduced, allowing the UE to measure different subgroups more quickly.

[0812] Optionally, the seventh information indicates the first subgroup by indicating a number or a subgroup identifier. In this way, when the number of subgroups is large, the DCI signaling overhead can be reduced compared with the following scheme.

[0813] Optionally, the seventh information indicates the first subgroup in a bitmap manner. In this way, compared with the above aspect, when the number of subgroups is small, the DCI signaling overhead can be reduced.

[0814] Optionally, the seventh information is indicated by the first field in the DCI signaling.

[0815] Optionally, if there are multiple resource groups (in the first set, or in the first and second sets, or in the first set, the second set and the third set) with corresponding subgroups, the size of the first domain is determined according to the first number of subgroups, and the first number is the maximum number of subgroups contained in the multiple resource groups (for example, there are 3 resource groups with corresponding subgroups, and their numbers are M1, M2, and M3 respectively, then the first number is the maximum value of the three). In this way, compared with the following direction, RRC signaling can be reduced.

[0816] Optionally, the size of the first field is configured by the network, which can increase system flexibility compared to the above solution. Optionally, if the value of the first field is greater than the number of subgroups corresponding to the first resource group, the indication of the first field is ignored, or a subgroup is determined according to a first predetermined rule (e.g., RRC pre-configured or protocol pre-specified).

[0817] Optionally, when the seventh information value is the first value, the terminal device performs measurement and / or reporting based on the first resource group, where the first value can be a predetermined reserved value (this is equivalent to a fallback mode, that is, not using the subgroup but directly using the resource group).

[0818] Optionally, if the first configuration information indicates a second set, the terminal device also performs measurements and / or reports based on the second subgroup (i.e., based on the first subgroup, similar to the following places), and the second subgroup is determined according to the seventh information, or the second subgroup is determined according to the second predetermined rule, or the second subgroup is determined according to the correspondence between the second subgroup and the first subgroup configured by the network (for example, the network indicates the correspondence through RRC signaling or MAC CE signaling). In this way, by measuring the interference, the system can be assisted in making a better selection of the beam.

[0819] Optionally, if the first configuration information indicates a third set, the terminal device also performs measurements and / or reports based on the third subgroup, and the third subgroup is determined according to the seventh information, or the third subgroup is determined according to the second predetermined rule, or the third subgroup is determined according to the correspondence between the third subgroup and the first subgroup configured by the network (for example, the network indicates the correspondence through RRC signaling or MAC CE signaling). In this way, by measuring the interference, the system can be assisted in making a better selection of the beam.

[0820] Based on any of the foregoing, optionally, if the measurement and / or reporting of the terminal device (or a certain measurement and / or reporting, which are similar and will not be elaborated on one by one) corresponds to the first resource group (for example, the configuration corresponding to the current measurement and / or reporting indicates the first resource group), the terminal device performs measurement and / or reporting based on the first subgroup.

[0821] Optionally, if the first configuration information indicates a second set and the second subgroup is also indicated by the network, the terminal device also needs to perform measurements and / or reports based on the second subgroup (that is, based on the first subgroup, the following several places are similar). In this way, by measuring the interference, the system can be assisted in making a better selection of the beam.

[0822] Optionally, if the first configuration information indicates a third set and the third subgroup is also indicated by the network, the terminal device also needs to perform measurements and / or reports based on the third subgroup. In this way, the interference can be measured to assist the system in making a better selection of the beam.

[0823] Optionally, if the first configuration information indicates a second set, but the network does not indicate a second subgroup, the terminal device also performs measurements and / or reports based on the second subgroup. The second subgroup is determined according to a second predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the subgroup of the first resource group and the subgroup of the second resource group configured by the network (for example, the network indicates the correspondence through RRC parameters), or the second subgroup is the second resource group, thereby reducing signaling overhead.

[0824] Optionally, if the first configuration information indicates a third set, but the network does not indicate a third subgroup, the terminal device also performs measurements and / or reports based on the third subgroup. The third subgroup is determined according to a second predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the subgroup of the first resource group and the subgroup of the third resource group configured by the network (for example, the network indicates the correspondence through RRC parameters), or the third subgroup is the third resource group, thereby reducing signaling overhead.

[0825] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group (for example, the first resource group is indicated in the configuration corresponding to the current measurement and / or reporting), and the terminal device does not receive the seventh information, or does not receive the fourth information, the terminal device performs measurement and / or reporting based on the first resource group (that is, based on the first resource group itself, not its subgroup). In this way, defining the default behavior when the UE does not receive the first information can reduce additional signaling design.

[0826] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group and the second resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group and the second resource group.

[0827] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group and the third resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group and the third resource group.

[0828] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group, the second resource group and the third resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group, the second resource group and the third resource group.

[0829] Example 3 (DCI Directly Activates Resources)

[0830] Based on any of the embodiments regarding the first configuration information, a terminal device receives first information sent by a network device, wherein the first information indicates one or more resources (or signal resources) of a first resource group. For the sake of convenience, the indicated one or more resources are referred to as a first subgroup (in practice, this subgroup may not be clearly defined), wherein the first resource group belongs to one of the one or more resource groups in the first set. The first information is transmitted via DCI information. Thus, compared with the scheme of configuring subgroups using RRC or MAC CE, the use of DCI can reduce processing delays. It should be noted that the first information, the second information, and the third information in embodiment 1 are transmitted via MAC CE, while the first information, the second information, and the third information in this embodiment 3 are transmitted via DCI.

[0831] Optionally, the terminal device may also receive second information and / or third information.

[0832] Optionally, the resources in the first subgroup are indicated by a bitmap, where each bit corresponds to a resource. In this way, compared with directly indicating the resource numbering scheme, signaling overhead can be reduced.

[0833] Optionally, the resources in the first subgroup are indicated by numbers, where the numbers belong to the numbers of the resources in the first resource group. For example, 0 may correspond to the first resource in the first resource group, and 1 may correspond to the second resource in the first resource group. In this way, compared with the previous scheme, when the number of resources in the subgroup is relatively small, or when the number of resources in the first resource group is relatively small, the signaling overhead can be reduced.

[0834] Optionally, the resources in the first subgroup are indicated using a bitmap, with each bit corresponding to T resources. This reduces the number of corresponding DCI bits. As an example, the value of T is configured by the network. As another example, the value of T is specified by the protocol. Optionally, the T resources are T consecutive resources in the first resource group. Optionally, the T resources are evenly spaced resources in the first resource group.

[0835] Optionally, the resources belonging to the first subgroup are determined by two parts of information (corresponding to the first indication and the second indication mentioned above), the first part of information indicates the starting resources in the first resource group, and the second part of information indicates the ending resources in the first resource group. The resources between the starting resources and the ending resources all belong to the first subgroup, where the starting resources may belong to the first subgroup or not, and the ending resources may belong to the first subgroup or not.

[0836] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group (for example, the first resource group is indicated in the configuration corresponding to the current measurement and / or reporting), and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group (that is, based on the first resource group itself, not its subgroup). In this way, defining the default behavior when the UE does not receive the first information can reduce additional signaling design.

[0837] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group and the second resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group and the second resource group.

[0838] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group and the third resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group and the third resource group.

[0839] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first resource group, the second resource group and the third resource group, and the terminal device does not receive the first information, the terminal device performs measurement and / or reporting based on the first resource group, the second resource group and the third resource group.

[0840] Optionally, the descriptions of the first information, the second information, and the third information in Embodiment 3 may be combined with the descriptions of the first information, the second information, and the third information in Embodiment 1.

[0841] Optionally, the description of measurement and / or reporting in embodiment 3 may be combined with the description of measurement and / or reporting in embodiment 1. Optionally, the description of measurement and / or reporting in embodiment 2 may be combined with the description of measurement and / or reporting in embodiment 1.

[0842] Optionally, Embodiment 1, Embodiment 2, and Embodiment 3 may be applied to one or more of the following situations:

[0843] Case 1: AI / ML-based (or AI-based) beam management process.

[0844] Case 2: AI / ML-based spatial domain beam prediction, or AI-based spatial domain beam prediction. For example, based on the measurement results of G1 wide beams, the best G2 narrow beams (i.e., the top-G2 narrow beams) are predicted. For example, based on the measurement results of G1 beams, the best G2 narrow beams (i.e., the top-G2 narrow beams) among G3 beams are predicted, where G1 beam is part of the 3G beams.

[0845] Case 3: AI / ML-based temporal beam prediction (time-domain beam prediction), or AI-based temporal beam prediction. For example, the current and / or previous measurement results of the G1 beam are used to predict the best G2 beams (i.e., the top-G2 beams) at a future moment or at certain future moments. The value of G2 may vary at different future moments.

[0846] Optionally, in the above method, neither the AI ​​algorithm nor the ML algorithm may be used, and other non-AI, non-ML algorithms, such as a linear prediction algorithm, may be used.

[0847] Optionally, in Embodiment 1, Embodiment 2, and Embodiment 3, before the terminal device receives the first configuration information, the terminal device may also report the first terminal capability.
