Abstract
Description
Wireless communication method, device, and storage medium Technical Field
[0001] The embodiments of the present application relate to the field of mobile communication technologies, and in particular to a wireless communication method and device, and a storage medium. Background Art
[0002] In related technologies, to ensure effective beam management (for example, the network selects a preferred downlink transmit beam (DL Tx beam) to transmit signals to a specific user), the communication system needs to know the communication quality of the corresponding beam. This involves measuring and reporting the beam (or reference signal). In actual systems, network equipment may not directly instruct the UE to measure a specific beam. Instead, it may use the measured beam to transmit a reference signal (RS), allowing the UE to measure the RS. The measurement result corresponding to the RS can reflect the transmission quality of the corresponding beam.

[0040] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.
[0041] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.
[0042] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto.

For example, predefined can refer to a definition in a protocol. It should also be understood that in the embodiments of the present application, the “protocol” can refer to a standard protocol in the field of communications, such as an LTE protocol, an NR protocol, and related protocols used in future communication systems, and the present application does not limit this.
[0053] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.
[0054] NR / 5G systems are designed to support wide-bandwidth communications in high-frequency bands (e.g., bands above 6 GHz). As the operating frequency increases, path loss increases during transmission, impacting the coverage capabilities of high-frequency systems. To effectively ensure high-band NR system coverage, an effective technical solution is to utilize multiple beams (or hybrid beams) based on massive MIMO antenna arrays to improve coverage.
[0055] In a typical 2G / 3G / 4G system, 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.
[0056] The NR / 5G Multi-beam system uses different beams to cover the entire cell. Each beam covers a smaller area, and multiple beams are used to achieve full coverage of the cell through time sweeping. Currently, different beams are identified by the different signals they carry:
[0057] Different synchronization blocks (SS blocks, SSBs) are transmitted on different beams. UE can distinguish different beams by different SSBs.
[0058] Different channel state information reference signals (CSI-RS) are transmitted on different beams, and the UE identifies different beams through the CSI-RS signals / CSI-RS resources.
[0059] Therefore, the following discussions are based on visible signals (which actually correspond to one or some physical beams, but may not be explicitly stated in the standard).
[0060] In a multi-beam system, the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH) can be transmitted using different downlink transmit beams:
[0061] For systems below 6G, 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] In millimeter wave systems, the UE may have analog beams, requiring the corresponding downlink receive beam to receive the signal from 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 through the quasi co-location (Quasi Co-Location, QCL) between signals (for example: QCL-TypeD type). On the UE side, the determination of receiving the corresponding channel / signal is also based on the quasi co-location assumption. Among them, the QCL quasi-co-location assumption is indicated by the transmission configuration indication (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 Media Access Control Control MAC CE, and / or Downlink Control Information (DCI)).
[0064] Future communication systems (e.g., 6G wireless communication systems, new generation Wi-Fi) may also adopt multi-beam technology.
[0065] Beam / reference signal measurement and reporting
[0066] 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 will use a beam to transmit a certain RS and let the UE measure the transmitted RS. The measurement result corresponding to the RS can be reflected as 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 to measure, but 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.
[0067] In fact, measuring the RS may not only be used to assist beam management, but may also be used to measure current channel information to assist MIMO transmission.
[0068] 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.
[0069] RS transmission may have different forms, such as aperiodic (AP) transmission, semi-persistent (SP) transmission, and periodic (P) transmission.
[0070] The measurement results can be reported through various mechanisms, including AP reporting, SP reporting, and P reporting.
[0071] TCI state
[0072] To improve reception performance, terminals can leverage the characteristics of the transmission environment to improve their reception algorithms. For example, channel statistics can be leveraged to optimize the design and parameters of the channel estimator. In NR systems, these characteristics are represented by the QCL state (QCL-Info).
[0073] If the downlink transmission comes from different transmission reception points (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 status.
[0074] A TCI state can contain the following configurations:
[0075] TCI status identity document (ID), used to identify a TCI status;
[0076] QCL information 1;
[0077] QCL information 2 (optional).
[0078] A QCL message can contain the following information:
[0079] QCL type configuration, which can be one of QCL type A (type A), QCL type B (type B), QCL type C (type C), or QCL type D (type D);
[0080] QCL reference signal configuration, including the serving cell ID, bandwidth part (BWP) ID, and reference signal identifier. The reference signal identifier can be a CSI-RS resource ID or a synchronization signal block (SSB) index. An SSB is also called a synchronization signal (SS) / physical broadcast channel (PBCH) block.
[0081] If both QCL information 1 and QCL information 2 are configured, the QCL type of one or more of the QCL information must be one of QCL typeA, QCL typeB, and QCL typeC, and the QCL type of the other QCL information (if configured) must be QCL type D.
[0082] The definitions of different QCL type configurations are as follows:
[0083] QCL-Type A: {Doppler shift, Doppler spread, average delay, delay spread};
[0084] QCL-TypeB: {Doppler shift, Doppler spread};
[0085] QCL-TypeC: {Doppler shift, average delay};
[0086] QCL-TypeD: {Spatial Rx parameter}.
[0087] In the protocol, the TCI-State related configuration is as follows:
[0088] In the NR system, the network side can indicate the corresponding TCI status for the downlink signal or downlink channel.
[0089] 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 type A, type B, or type C, the terminal device can assume that the large-scale parameters of the target downlink channel or 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. Large-scale parameters include: Doppler delay, average delay, spatial reception parameters, etc.
[0090] 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 typeD, the terminal device can use the same receiving beam (i.e., Spatial Rx parameter) as that for receiving the reference SSB or reference CSI-RS resource to receive the target downlink signal. Usually, the target downlink channel or target 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.
[0091] For the downlink control channel, the TCI status of the corresponding CORESET can be indicated by RRC signaling or RRC signaling + MAC signaling.
[0092] For the downlink data channel, the available TCI state set is indicated by RRC signaling, and some of the TCI states are activated by MAC layer signaling. Finally, the TCI state indication field in the downlink control information (DCI) indicates one or two TCI states from the activated TCI states for the DCI-scheduled PDSCH. In one example, as shown in Figure 2, N candidate TCI states are indicated by RRC signaling, and the N candidate TCI states constitute the available TCI state set. K candidate TCI states are activated by MAC layer signaling to obtain K activated TCI states, and one or two used TCI states are indicated from the activated TCI states by DCI for the DCI-scheduled PDSCH. The case of 2 TCI states is for scenarios similar to multiple TRPs.
[0093] The TCI states described above only apply to downlink channels and signals and have many limitations in NR systems. To provide a more unified uplink and downlink beam management mechanism for NR systems, the concept of a unified TCI state was proposed, which adds important new features, as follows:
[0094] Designed two unified TCI state modes
[0095] Mode 1: Contains one TCI state, which applies to both uplink and downlink channels and signals. We call this TCI state the joint TCI state.
[0096] Mode 2: Contains two types of TCI states: the DL TCI state applies only to downlink channels and signals, and the UL TCI state applies only to uplink channels and signals. We call this type of TCI state the separate TCI state.
[0097] Downlink channels (partial PDCCH, PDSCH) and signals (aperiodic CSI-RS) use the same downlink transmit indicator beam, using DL TCI state or joint TCI state;
[0098] Uplink channels (PUCCH, PUSCH) and signals (SRS) use the same uplink transmit beam and use UL TCI state or joint TCI state;
[0099] Unified TCI state can be dynamically updated and indicated using MAC CE and / or DCI;
[0100] Applicable to carrier aggregation scenarios, where the beam indication on a single CC can be applied to multiple different CCs;
[0101] Uplink beam indication can be given simultaneously with uplink power control parameters via the UL TCI state or joint TCI state;
[0102] Supports inter-cell beam management.
[0103] For each CORESET on CC, it can be divided into the following four types:
[0104] CORESET A: It is associated only with the UE-specific search space and can be considered as a UE-specific downlink control channel resource. It must follow the indicated unified TCI state(s).
[0105] CORESET B: It is associated only with the cell-common search space. Whether it can follow the unified TCI state(s) indicated by the NW depends on the NW RRC configuration.
[0106] CORESET C: It is associated with both the UE-specific search space and the cell-common search space. Whether it can follow the unified TCI state(s) indicated by the NW depends on the NW RRC configuration.
[0107] CORESET 0: It must be associated with the cell common search space and can also be associated with the UE-specific search space. Whether it can follow the unified TCI state(s) indicated by the NW depends on the NW RRC configuration.
[0108] The TCI state mentioned in the embodiments of the present application, if the TCI state is not clearly specified, may include any of the TCI states mentioned above, that is, the TCI state can be a joint TCI state, a separate TCI state, a DL TCI state, a UL TCI state, a combination of them (that is, including multiple different types of TCI states), or a TCI state in R15 / R16.
[0109] In the measurement / reporting mechanism of the related technology, the network equipment configures the corresponding RS 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.
[0110] 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 groups of signals.
[0111] Based on the RS group mechanism, the following processing methods can be used:
[0112] Different RS groups are pre-configured via RRC, and then DCI is used to trigger aperiodic reporting, thereby enabling 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 and impacting control channel coverage;
[0113] · Using RRC to configure the currently required RS group. This approach also has many disadvantages: 1. Frequent RRC signaling transmission leads to a large total RRC signaling overhead; 2. The delay caused by RRC signaling configuration is large, which prevents the network from allowing the UE to quickly measure certain RSs, affecting the overall system performance.
[0114] 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 above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application.

[0118] The wireless communication method provided in the embodiment of the present application is applied to a network device, as shown in FIG4 , and includes:
[0119] S401. A network device sends first configuration information to a terminal device, where the first configuration information indicates a first set, the first set includes one or more first resource groups, and the first resource groups are used for channel measurement and / or beam measurement. The first configuration information is transmitted through radio resource control (RRC) signaling.
[0120] S402. The network device sends second configuration information to the terminal device, where the second configuration information is used to indicate one or more first subgroups corresponding to the first target resource group, where the resources included in the first subgroup belong to the first target resource group, and where the first target resource group is one of the one or more resource groups included in the first set. The second configuration information is transmitted through RRC signaling.
[0121] In the embodiments of the present application, "one or more" can be understood or described as "at least one". For example, "one or more first resource groups" can also be understood or described as "at least one first resource group". For another example, "one or more first subgroups" can also be understood or described as "at least one first subgroup".
[0122] The wireless communication method shown in FIG. 3 or FIG. 4 is further described below.
[0123] The terminal device receives first configuration information sent by the network device, where the first configuration information indicates a first set, where the first set includes one or more first resource groups (Resource set), each first resource group includes one or more first resources, and the first resources are used for channel measurement and / or beam measurement. Here, it can be understood that the first resource group is a resource group in the first set. The first configuration information is used to configure one or more resource groups included in the first set, and indicates the resources included in each resource group.
[0124] In one example, the first set G1 is indicated by X1 = 2 resource groups, which are respectively denoted as G1_S1 and G1_S2, where G1_S1 contains resources {A1, A2, A3, A4, A5, A6, A7, A8}, and G1_S2 contains resources {B1, B2, B3, ...}. It should be noted that for the sake of convenience, the value of X1 is 2 as an example. Other values of X1 can be directly expanded and will not be detailed one by one. In addition, for the sake of simplicity, G1_S1 is taken as an example containing 8 resources. Other numbers can be directly expanded, such as: 4, 16, 32, etc.
[0125] In the embodiment of the present application, the first resource is a resource in the first set, which may also be replaced by a signal resource, a reference signal, or a reference signal resource. The type of the first resource may include one of the following: CSI-RS resource and SSB.
[0126] Each first resource group in the first set is used for channel measurement, or for beam measurement, or for both channel measurement and beam measurement.
[0127] The first resource group in the first set is used for channel measurement, or for beam measurement, or for both channel measurement and beam measurement. It can also be understood that the first resource in one or more first resource groups in the first set is used for channel measurement, or for beam measurement, or for both channel measurement and beam measurement.
[0128] Based on the first set indicated by the first configuration information, the terminal device can perform channel measurement and / or beam measurement based on the first resource group in the first set, and the terminal device can also report the measurement results to the network device.
[0129] Based on receiving the first configuration information sent by the network device, the terminal device also receives second configuration information sent by the network device, where the second configuration information indicates one or more first subgroups (subsets) for the first target resource group, and the resources in the first subgroup are referred to as first resources. The first target resource group belongs to a first resource group among the one or more first resource groups in the first set, and the first subgroup can be understood as a subgroup corresponding to the first resource group, and the first resources contained in each of the one or more first subgroups belong to the first target resource group.
[0130] For a network device, based on sending the first configuration information to the terminal device, second configuration information is also sent to the terminal device, where the second configuration information indicates one or more first subgroups (subsets) for the first target resource group, and the resources in the first subgroup are referred to as first resources. The first target resource group belongs to a first resource group among the one or more first resource groups in the first set, and the first subgroup can be understood as a subgroup corresponding to the first resource group. The first resources contained in each of the one or more first subgroups belong to the first target resource group.
[0131] In an embodiment of the present application, the second configuration information is used to indicate or configure corresponding multiple subgroups for one resource group in one or more resource groups in the first set, wherein the first resource group targeted by the second configuration information is called the first target resource group.
[0132] In the embodiment of the present application, the network device configures multiple subgroups for the first target resource group, which can effectively reduce signaling overhead.
[0133] In one example, the first set G1 is indicated with X1=2 resource groups, which are respectively denoted as G1_S1 and G1_S2, where G1_S1 contains resources {A1, A2, A3, A4, A5, A6, A7, A8}. The second configuration information can indicate K subsets for resource group G1_S1. The first subset can contain resources {A1, A2, A3, A4}. If a second subset is indicated, one example is that the second subset can contain resources {A3, A4, A5, A6}, and another example is that the second subset can contain resources {A5, A6, A7, A8}. In this case, resource group G1_S1 belongs to the first target resource group.
[0134] For simplicity, the following example uses a K1 value of 2. Other values can be easily expanded. Also, for simplicity, a subgroup is taken as an example with 4 resources. Other values can be easily expanded, such as 2, 3, 5, 6, 8, etc.
[0135] In the embodiment of the present application, the network device may use a variety of different methods to infer which beams have better channel quality for a certain UE, thereby determining which first resources in the corresponding first target resource group are included in a first subgroup. For example:
[0136] 1. The network equipment 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 (such as measurement results obtained by the network on UE signal transmission or uplink transmission). Deep learning is a commonly used AI method.
[0137] 2. Based on its own measurement results, the UE uses machine learning methods, artificial intelligence methods, or statistical methods to predict the several beams that may be best for it, and then reports the prediction results to the network equipment.
[0138] This approach of using AI / ML technologies to assist with beam management is 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 (e.g., the UE or the network) may not be aware of which AI / ML technology the other party (e.g., the network or the UE) is using. In addition to using AI / ML technologies, the network or the UE can also use non-AI / ML technologies to implement similar functions or achieve similar results.
[0139] In an embodiment of the present application, the first configuration information is configured via RRC signaling. In one example, for an NR system, a resource group in the first set may be configured via an information element non-zero-power (NZP)-CSI-RS-resource set (NZP-CSI-RS-ResourceSet) in RRC signaling, and resources in the resource group are indicated via an information element NZP-CSI-RS-Resource in RRC signaling.
[0140] In the embodiment of the present application, the second configuration information is configured through RRC signaling, thereby realizing the configuration of the subgroup.
[0141] It is understandable that the first configuration information and the second configuration information may be transmitted through the same RRC signaling or through different RRC signaling.
[0142] In an embodiment of the present application, a terminal device receives first configuration information and second configuration information sent by a network device, where the first configuration information indicates a first set, and the first set includes one or more first resource groups. The second configuration information is used to indicate one or more first subgroups corresponding to a first target resource group in one or more first resource groups, so that the network device configures a subgroup for the resource group on the basis of beam measurement and / or beam measurement basis to the terminal device, so that the terminal device can measure and / or report signals based on the subgroup, thereby flexibly selecting the measurement signal according to the communication environment.
[0143] In some embodiments, the first configuration information and the second configuration information are the same configuration information or two independent configuration information.
[0144] If the first configuration information and the second configuration information are the same configuration information, the one or more first resource groups included in the first set and the one or more first subgroups configured for the first target resource group are simultaneously indicated by the same configuration information, thereby reducing signaling overhead.
[0145] If the first configuration information and the second configuration information are two independent pieces of configuration information, the flexibility of signaling can be increased, facilitating network optimization and implementation.
[0146] In some embodiments, if the first configuration information and the second configuration information are two independent pieces of configuration information, the second configuration information is further used to indicate the first target resource group.
[0147] When the second configuration information indicates the first target resource group, it can flexibly indicate for which first resource group the sub-group configuration is to be performed, thereby improving the flexibility of the system.
[0148] In the embodiment of the present application, if the second configuration information does not indicate the first target resource group, the first target resource group may be determined according to a predefined rule.
[0149] In some embodiments, if the first configuration information and the second configuration information are two independent configuration information, the first configuration information and the second configuration information are transmitted in the same RRC information element.
[0150] The first configuration information and the second configuration information are transmitted in the same RRC IE, reducing signaling overhead.
[0151] In some embodiments, the second configuration information is further used to indicate a subgroup identifier of each first subgroup in one or more first subgroups included in the first target resource group.
[0152] For one or more first subgroups included in the first target resource group, the second configuration information indicates an identifier of the corresponding first subgroup, that is, a subgroup identifier.
[0153] In one example, the second configuration information may indicate K subsets for the resource group G1_S1, and the second configuration information may indicate a corresponding subset identifier (subset index, or subset indicator) for the first first subset corresponding to the resource group G1_S1, so as to facilitate subsequent signaling to indicate the corresponding subgroup, such as selecting or activating a subgroup.
[0154] The second configuration information indicates an identifier of the corresponding first subgroup, so as to facilitate subsequent signaling to indicate the corresponding subgroup, such as selecting or activating a certain subgroup.
[0155] In some embodiments, the second configuration information indicates one or more first subgroups corresponding to the first target resource group in one of the following ways:
[0156] Subgroup indication method 1: indicating the resources included in the first subgroup by means of a bitmap;
[0157] Subgroup indication mode 2: for a first subgroup in the one or more first subgroups, indicating the number of the resource included in the first subgroup, where the number of the resource is the number of the resource in the first target resource group;
[0158] Subgroup indication method three: for a first subgroup among the one or more first subgroups, indicating the identifier of the resource included in the first subgroup, where the identifier of the resource is the identifier in the resource configuration information of the resource.
[0159] In the first subgroup indication method, each of the one or more first subgroups corresponding to the first target resource group indicates which resources in the first resource group belong to this subgroup by means of a bitmap.
[0160] In one example, an 8-bit bitmap is used to indicate the first subgroup corresponding to the first resource group G1_S1, where four bits set to 1 indicate resources A1, A2, A3, and A4. Optionally, the four bits set to 1 can be the first four bits (the leftmost four bits) or the last four bits (the rightmost four bits).
[0161] Indicating the first subgroup based on the first subgroup indication mode can reduce signaling overhead when the number of resources in the subgroup is relatively large or the number of resources in the first resource group is relatively large.
[0162] In subgroup indication method 2, each of the one or more first subgroups corresponding to the first target resource group indicates which resources in the first target resource group belong to the first subgroup by indicating one or more numbers. The number is the number of the resource within the first resource group. For example, 0 may correspond to the first resource in the first target resource group, and 1 may correspond to the second resource in the first target resource group.
[0163] In one example, for the first subgroup corresponding to resource group G1_S1, including resources A1, A2, A3, and A4 in resource group G1_S1, 0, 1, 2, and 3 are directly indicated to correspond to the first resource, second resource, third resource, and fourth resource in resource group G1_S1, that is, corresponding to resources A1, A2, A3, and A4, or 1, 2, 3, and 4 are directly indicated to correspond to the first resource, second resource, third resource, and fourth resource in resource group G1_S1, that is, corresponding to resources A1, A2, A3, and A4.
[0164] Indicating the first subgroup based on the second subgroup indication mode can reduce signaling overhead when the number of resources in the subgroup is relatively small or the number of resources in the first resource group is relatively small.
[0165] In subgroup indication method three, each first subgroup in one or more first subgroups corresponding to the first target resource group indicates which resources in the first target resource group belong to this first subgroup by indicating one or more identifiers, wherein the identifier is the identifier in the resource configuration information.
[0166] In one example, for the first subgroup of resource group G1_S1, the corresponding identifiers of A1, A2, A3, and A4 can be directly indicated, where the corresponding identifiers of A1, A2, A3, and A4 are the corresponding identifiers contained in the respective configuration information of resources A1, A2, A3, and A4.
[0167] In subgroup indication mode three, if the resource is a CSI-RS resource (because the CSI-RS resource here is to actually send the CSI-RS signal, it can also be called NZP-CSI-RS-Resource), then in the NR system the identifier is nzp-CSI-RS-ResourceId.
[0168] Indicating the first subgroup based on subgroup indication mode 3 and directly using the resource identifier itself can simplify the processing of the terminal device. It should be noted that mode 3 may increase the overhead of RRC signaling.
[0169] In some embodiments, if the first set includes at least two first resource groups, the second configuration information is used to indicate a subgroup corresponding to each first resource group in the at least two first resource groups.
[0170] In the embodiment of the present application, the second configuration information may indicate first subgroups corresponding to multiple first resource groups.
[0171] As an example, the first set G1 indicates X1=2 resource groups, which are respectively denoted as G1_S1 and G1_S2. The second configuration information may indicate K2 (K2>=1) subgroups for resource group G1_S2. In this case, resource group G1_S2 belongs to the first target resource group.
[0172] As another example, the first set G1 is indicated by X1=2 resource groups, and these two resource groups are respectively recorded as G1_S1 and G1_S2. The second configuration information may indicate K1 (K1>=1) and K2 (K2>=1) subgroups for resource group G1_S1 and resource group G1_S2, respectively. At this time, resource group G1_S1 and resource group G1_S2 both belong to the first target resource group.
[0173] If the first configuration information and the second configuration information are the same configuration information, the second configuration information indicates the first subgroup corresponding to multiple first resource groups, and the signaling carrying the second configuration information sent by the network device to the terminal device may include multiple second configuration information, and the multiple configuration information can be implemented through a sequence (SEQUENCE) structure, wherein each element in the SEQUENCE structure corresponds to one second configuration information.
[0174] If the first configuration information and the second configuration information are the same configuration information, the second configuration information indicates the first subgroup corresponding to multiple first resource groups, and the signaling carrying the second configuration information and the first configuration information sent by the network device to the terminal device may include multiple first configuration information and multiple first configuration information, and the multiple first configuration information is implemented through a sequence (SEQUENCE) structure, namely SEQUENCE1, and the multiple second configuration information is implemented through a sequence (SEQUENCE) structure, namely SEQUENCE2, wherein each element in SEQUENCE1 corresponds to a first configuration information, and each element in SEQUENCE2 corresponds to a second configuration information.
[0175] In some embodiments, based on the wireless communication method shown in FIG3 , as shown in FIG5 , the method includes:
[0176] S501. The terminal device receives first indication information sent by the network device, where the first indication information is used to indicate a first target subgroup corresponding to the first target resource group, and the first target subgroup is one of the one or more subgroups corresponding to the first target resource group.
[0177] At this time, based on the wireless communication method shown in FIG4 , as shown in FIG6 , the method includes:
[0178] S601. The network device sends first indication information to the terminal device, where the first indication information is used to indicate a first target subgroup corresponding to the first target resource group, and the first target subgroup is one of the one or more subgroups corresponding to the first target resource group.
[0179] The network device sends first indication information to the terminal device, where the first indication information indicates a first target subgroup corresponding to the first target resource group, and the first target subgroup belongs to one or more first subgroups corresponding to the first target resource group.
[0180] The first indication information includes one or more of the following information: resource group indication information indicating the first target resource group, subgroup indication information indicating the first target subgroup, thereby indicating the first target subgroup in the first target resource group.
[0181] In the embodiment of the present application, the first indication information indicates the first target subgroup corresponding to the first target resource group, which can flexibly indicate which subgroup or subgroups to use, thereby reducing signaling overhead and improving system performance.
[0182] In some embodiments, the first indication information is transmitted in one of the following two ways:
[0183] Transmission method 1: The first indication information is transmitted via one of the following methods:
[0184] Radio Resource Control (RRC);
[0185] Media Access Control Unit MAC CE.
[0186] Transmission mode 2: The first indication information is transmitted via downlink control information DCI.
[0187] Next, the transmission mode 1 is described.
[0188] When the first indication information is transmitted via RRC, it has high reliability, but has large signaling overhead and high processing delay.
[0189] When the network device transmits the first indication information through RRC or MAC CE, the first target subgroup indicated by the first indication information is activated, and the activated first target subgroup can be used for corresponding measurement and / or reporting on the terminal device side.
[0190] When the first indication information is transmitted through MAC CE, the signaling overhead is small, the processing delay is low, and the reliability is lower than the reliability of the first indication information transmitted through RRC, but higher than the reliability of the first indication information transmitted through DCI, thereby achieving a better compromise and balance among multiple system design indicators.
[0191] In some embodiments, the first target subset satisfies one or more of the following:
[0192] The resources included in the first target subgroup belong to the first serving cell;
[0193] The resources included in the first target subgroup belong to a first BWP.
[0194] Here, it does not matter whether the first indication information indicates the first serving cell and / or the first BWP. The resources included in the first target subgroup belong to the first serving cell and / or the first BWP. In some embodiments, the first serving cell can be understood as the serving cell accessed by the terminal device. In some embodiments, the first BWP can be understood as the BWP used by the terminal device.
[0195] In some embodiments, if the first indication information is transmitted via a MAC CE, the first indication information is further used for one of the following:
[0196] Indicating a first serving cell, where the first indication information is applied to the first serving cell;
[0197] Indicate a first bandwidth part BWP, the first indication information being applied to the first BWP;
[0198] indicating a second serving cell;
[0199] The second serving cell is not indicated;
[0200] Indicates the second BWP;
[0201] The second BWP is not indicated.
[0202] In the embodiment of the present application, whether the first indication information indicates the first serving cell, whether it indicates the second serving cell, and whether it indicates the first BWP are optional.
[0203] In the embodiment of the present application, the contents indicated by the first indication information can be combined if they are not contradictory. For example, the first indication information indicates the first serving cell but does not indicate the second serving cell. Another example is that the first indication information indicates the first BWP but does not indicate the second BWP.
[0204] The first indication information indicates the first service cell, which can also be understood as the first indication information indicating the first carrier. The first carrier is the carrier of the first service cell. The first indication information indicates the first service cell, which can also be understood as the MAC CE that transmits the first indication information, that is, the first MAC CE indicates the first service cell. The first indication information is applied to the first service cell.
[0205] In some embodiments, the first MAC CE indicates the first serving cell through a serving cell ID (Serving Cell ID).
[0206] The first indication information indicates the first BWP, which can be understood as the first MAC CE indicating the first BWP. The first indication information is applied to the first BWP. In some embodiments, the first MAC CE can indicate the first BWP through a BWP ID.
[0207] The second serving cell is a cell other than the first serving cell. The second BWP is a BWP other than the first BWP.
[0208] In some embodiments, the first indication information indicates a first serving cell, and the resources included in the first target subgroup are in or belong to the first serving cell.
[0209] In some embodiments, the first indication information indicates a first BWP, and the resources included in the first target subgroup are in or belong to the first BWP.
[0210] In some embodiments, if the first indication information indicates the second service cell, the resources included in the first target subgroup belong to the second service cell; if the first indication information does not indicate the second service cell, the resources included in the first target subgroup belong to the first service cell; if the first indication information indicates the second BWP, the resources included in the first target subgroup belong to the second BWP; if the first indication information does not indicate the second BWP, the resources included in the first target subgroup belong to the first BWP.
[0211] The first indication information indicates the second serving cell, which can also be understood as the first indication information indicating the second carrier or the first MAC CE indicating the second serving cell, and the resources within the first target subgroup are in the second serving cell or belong to the second serving cell. As an example, the first MAC CE can indicate the second serving cell using a serving cell ID (Serving Cell ID). The first indication information indicating the second serving cell can flexibly indicate the measured signals / resources of other cells.
[0212] The first indication information indicates the second BWP, which can also be understood as the first MAC CE indicating the second BWP, and the resources within the first target subgroup are within or belong to the second BWP. As an example, the first MAC CE can indicate the second BWP using a BWP ID. The first indication information indicating the second BWP can flexibly indicate the signals / resources being measured by other BWPs.
[0213] The first indication information does not or does not indicate the second serving cell, which can be understood as the first MAC CE does not indicate the second serving cell (or carrier), and the resources in the first target subgroup are in the first serving cell or belong to the first serving cell. The first indication information not indicating the second serving cell can reduce signaling overhead, but compared to the case where the first indication information indicates the second serving cell, it cannot indicate the measured signals of other cells / carriers.
[0214] The first indication information does not or does not indicate the second BWP, which can be understood as the first MAC CE not indicating the second BWP, and the resources in the first target subgroup are in the first BWP or belong to the first BWP. The first indication information not indicating the second BWP can reduce signaling overhead, but compared to the case where the first indication information indicates the second BWP, it cannot indicate the measured signals of other BWPs.
[0215] In some embodiments, based on the wireless communication method shown in FIG7 , the method further includes:
[0216] If the target signal to be measured and / or reported corresponds to the first target resource group, the terminal device performs measurement and / or reporting based on the first target subgroup.
[0217] If the transmission mode of the first indication information is transmission mode one, the measurement and / or reporting of the terminal device or a certain measurement and / or reporting corresponds to the first target resource group, then the terminal device measurement is based on the first target subgroup for measurement and / or reporting.
[0218] If the transmission mode of the first indication information is transmission mode one, the terminal device does not receive the first indication information, the target signal to be measured corresponds to the first target resource group, and the terminal device performs measurement and / or reporting based on the first target resource group.
[0219] Next, the second transmission mode is described.
[0220] By transmitting the first indication information through DCI, the DCI signaling processing delay is lower, allowing the terminal device to measure different subgroups faster.
[0221] In some embodiments, the first indication information indicates the first target subgroup in one of the following ways:
[0222] Target subgroup indication mode 1: the first indication information indicates the subgroup identifier of the first target subgroup;
[0223] Target subgroup indication method 2: the first indication information indicates the first target subgroup in a bitmap manner.
[0224] In target subgroup indication mode 1, the second indication information indicates the first target subgroup by indicating a subgroup identifier. For example, if the first target resource group is G1_S1, the first indication information indicates the subgroup identifier (subset index, or subset indicator) of the first target subgroup corresponding to G1_S1. Indicating the first target subgroup by the subgroup identifier can reduce DCI signaling overhead when the number of first subgroups is large.
[0225] In the second target subgroup indication method, the first indication information indicates the first target subgroup in the form of a bitmap. For example, the bitmap has A bits. If a certain bit takes the value of 1, it indicates that the corresponding first subgroup is indicated, or if a certain bit takes the value of 1, it indicates that the corresponding first subgroup is activated. If a certain bit takes the value of 0, it means that the corresponding first subgroup is not activated. The meaning of activating the first subgroup is that in the corresponding measurement and / or reporting, it is necessary to perform measurement and / or reporting based on the first subgroup, that is, the first subgroup is the first target subgroup. If the A bits are all 0, it means that the corresponding measurement and / or reporting is based on the first resource group. By indicating the first target subgroup through bits, when the number of first subgroups is small, the DCI signaling overhead can be reduced.
[0226] In some embodiments, the first indication information is carried in a first field in the DCI, and a size of the first field is determined in one of the following ways:
[0227] Determined based on a first quantity, where the first quantity is a maximum quantity among quantities of subgroups corresponding to each resource group in the one or more resource groups corresponding to the first target subgroup;
[0228] Indicated by the network device.
[0229] The second indication information indicates the first subgroup via a first field in the DCI. As an example, one or some values of the first field correspond to the subgroup identifier of the first target subgroup.
[0230] 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) corresponding to the first target subgroup, the size of the first domain is determined according to the first quantity, which is the maximum number of subgroups contained in the multiple resource groups.
[0231] In one example, there are three resource groups corresponding to first target subgroups, including subgroups M1, M2, and M3, respectively. The first number is the maximum of M1, M2, and M3. Compared to a network setting indicating the size of the first domain, when the size of the first domain is determined by the first number, RRC signaling can be reduced.
[0232] If the size of the first domain is indicated or configured by a network configuration, the size of the first domain may be determined according to RRC configuration signaling of the network device, or determined according to MAC CE signaling sent by the network device.
[0233] The size of the first domain is indicated or configured by network configuration, which can increase system flexibility.
[0234] In some embodiments, if the size of the first domain is indicated by the network device, and the value of the first domain is greater than the number of first subgroups included in the first target resource group, the first target subgroup is determined by a set rule.
[0235] If the value of the first domain is greater than the number of subgroups corresponding to the first target resource group, the indication of the first domain is ignored, or a subgroup is determined according to a predetermined rule (such as RRC pre-configuration or protocol pre-specification), and the determined subgroup is the first target subgroup.
[0236] In some embodiments, the method further includes: the terminal device performing measurement and / or reporting based on the first target subgroup.
[0237] If the transmission mode of the first indication information is transmission mode 2, the measurement and / or reporting (or a certain measurement and / or reporting) of the terminal device corresponds to the first target resource group, and the terminal device performs measurement and / or reporting based on the first target subgroup.
[0238] If the transmission mode of the first indication information is transmission mode 2, the first indication information indicates a first value, and the terminal device performs measurement based on the first target resource group.
[0239] When the first field takes a first value, the terminal device performs measurement and / or reporting based on the first resource group, where the first value may be a predetermined reserved value, such as 0. This is equivalent to a fallback mode, that is, measurement and / or reporting is not performed using a subgroup, but measurement and / or reporting is performed directly using the resource group.
[0240] In one example, the first target resource group corresponds to 6 subgroups, which are respectively recorded as subgroup X, subgroup Y, subgroup Z, subgroup U, subgroup V, and subgroup W. As an example, the first indication information can indicate the activation of subgroup X (for example, when the second indication information takes a value of 1), or the activation of subgroup Y (for example, when the second indication information takes a value of 2), or the activation of subgroup Z (for example, when the second indication information takes a value of 3), or the activation of subgroup U (for example, when the second indication information takes a value of 4), or the activation of subgroup V (for example, when the second indication information takes a value of 5), or the activation of subgroup W (for example, when the second indication information takes a value of 6). Similarly, the first indication information may not activate any subgroup, for example, when its value is fixed to 0, no subgroup is activated. Wherein, if the first indication information indicates the activation of subgroup Z, the terminal device performs measurement and / or reporting based on subgroup Z; if the value of the first indication information is 0, that is, no subgroup is activated, the terminal device performs measurement and / or reporting based on the first target resource group.
[0241] In one example, a network device sends a MAC CE signaling to indicate that some subgroups (assuming subgroup X, subgroup Y, subgroup Z, subgroup U, subgroup V, and subgroup W) of one or more subgroups corresponding to a first resource group (assuming subgroup X, subgroup Y, subgroup Z, subgroup U, subgroup V, and subgroup W) can be indicated via DCI. The first indication information can indicate activation of subgroup X (for example, when the first indication information takes a value of 1), activation of subgroup Y (for example, when the first indication information takes a value of 2), or activation of subgroup Z (for example, when the first indication information takes a value of 3). Similarly, the first indication information may not activate any subgroups. For example, when its value is fixed to 0, no subgroup is activated.
[0242] If the transmission mode of the first indication information is transmission mode 2, the terminal device does not receive the first indication information, the target signal to be measured corresponds to the first target resource group, and the terminal device performs measurement and / or reporting based on the first target resource group.
[0243] In the embodiment of the present application, the scenarios in which the terminal device performs measurement and / or reporting include two scenarios:
[0244] Scenario 1: The terminal device performs measurement and / or reporting based on the first target subgroup;
[0245] Scenario 2: The terminal device performs measurement and / or reporting based on the first target resource group.
[0246] In the following cases, the terminal device performs measurements and / or reports in the scene:
[0247] Case A1: The transmission mode of the first indication information is transmission mode 1, the first indication information received by the terminal device indicates the first target subgroup, and the target signal measured and / or reported by the terminal device corresponds to the first target resource group;
[0248] In case A2, the transmission mode of the first indication information is transmission mode 2, and the first indication information received by the terminal device indicates the first target subgroup.
[0249] In the following cases, the terminal device performs measurements and / or reports in scenario 2:
[0250] Case B1: The transmission mode of the first indication information is transmission mode 1, and the terminal device does not receive the first indication information;
[0251] Case B2: The transmission mode of the first indication information is transmission mode 2, and the terminal device does not receive the first indication information;
[0252] Case B3: The transmission mode of the first indication information is transmission mode 2, and the value of the first indication information received by the terminal device is the first value.
[0253] Next, the following describes the interference measurement related content in a scenario where the terminal device performs measurement and / or reporting based on the first target subgroup.
[0254] In some embodiments, the terminal device is further configured to perform the following processing:
[0255] The terminal device performs interference measurement based on the second target subgroup and / or the third target subgroup, the second target subgroup corresponds to the second target resource group, the second target resource group is one of the one or more second resource groups included in the second set, and the second resource in the second resource group is used to perform interference measurement on the signal corresponding to the second resource, the third target subgroup corresponds to the third target resource group, the third target resource group is one of the one or more third resource groups included in the third set, and the third resource in the third resource group is used to perform interference measurement.
[0256] The terminal device performs interference measurement through the second target subgroup and / or the third target subgroup, and can assist the system in making better selection of beams by measuring the interference.
[0257] The signal corresponding to the second target subgroup is interfered with by the first target subgroup, so that the second target subgroup can perform interference measurement on the signal measured by the first target subgroup.
[0258] The second resources in the second target subgroup belong to a second set. The resources in the second set may correspond to a signal (e.g., SSB) or a reference signal (e.g., CSI-RS), or may correspond to a reference signal resource (e.g., CSI-RS resource). The second set includes multiple second resource groups, each of which is used for interference measurement. In other words, the resources in one or more resource groups in the second set are used by the terminal device to perform interference measurement on the corresponding signal or reference signal.
[0259] The resource group of the third target subgroup is the same as the resource group of the first target subgroup, so that the third target subgroup can perform interference measurement on the signal measured by the first target subgroup.
[0260] The third resource in the third target subgroup belongs to the third set, which contains one or more resource groups. 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, so that the terminal device performs interference measurement on the corresponding resource.
[0261] For the second target subgroup
[0262] In some embodiments, the first indication information is further used to indicate the second target subgroup; the second target subgroup is a second subgroup among the one or more second subgroups corresponding to the second target resource group.
[0263] In some embodiments, if the first indication information indicates a second serving cell and the first indication information indicates a second target subgroup, then the resources within the second target subgroup are in the second serving cell. In some embodiments, if the first indication information does not indicate a second serving cell and the first indication information indicates the second target subgroup, then the resources within the second target subgroup are in the first serving cell.
[0264] In some embodiments, if the first indication information indicates the second BWP and the first indication information indicates the second target subgroup, then the resources within the second target subgroup are within the second BWP. In some embodiments, if the first indication information does not indicate the second BWP and the first indication information indicates the second target subgroup, then the resources within the second target subgroup are within the first BWP.
[0265] In some embodiments, if the second target resource group corresponds to one or more second subgroups, and the first indication information does not indicate the second target subgroup, the second target subgroup is one of the following:
[0266] a second subgroup determined from the one or more second subgroups according to a first rule;
[0267] a second subgroup determined from the one or more second subgroups according to a first relationship, wherein the first relationship is a correspondence between a first subgroup in the first target resource group and a second subgroup in the second target resource group;
[0268] the second target resource group.
[0269] In some embodiments, if the second target resource group does not correspond to one or more second subgroups, the second target subgroup is one of the following:
[0270] a subgroup consisting of second resources determined from the second target resource group according to a second rule;
[0271] a subgroup consisting of second resources determined from the second target resource group according to a second relationship, wherein the second relationship is a correspondence between a first resource in the first target resource group and a second resource in the second target resource group configured by the network device;
[0272] the second target resource group.
[0273] In the embodiment of the present application, when the terminal device performs measurement and / or reporting based on the second target subgroup, the second target subgroup is determined in one of the following ways:
[0274] If the terminal device is configured with the second set and the first indication information indicates the second target subgroup, the terminal device also performs measurement and / or reporting based on the second target subgroup. In other words, the terminal device performs measurement and / or reporting based on the first target subgroup and the second target subgroup.
[0275] If the terminal device is configured with a second set, and one or more subgroups are indicated for the second target resource group in the second set, but the first indication information does not indicate the second target subgroup corresponding to the second target resource group, the terminal device performs measurement and / or reporting based on the second target subgroup, and the second target subgroup is determined according to a predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the first subgroup of the first target resource group and the second subgroup of the second target resource group configured by the network (for example, the network indicates the correspondence through an RRC parameter), or the second target subgroup is the second target resource group. At this time, the first indication information does not need to indicate the second target subgroup, which can reduce the signaling overhead of the first indication information.
[0276] If the terminal device is configured with a second set, but one or more subgroups are not indicated for the second target resource group, the terminal device performs measurement and / or reporting based on the second target subgroup, and the second target subgroup is determined according to a predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the first resource (or signal resource) of the first target resource group and the second resource (or signal resource) of the second target resource group configured by the network (for example, the network indicates the correspondence through an RRC parameter), or the second target subgroup is the second target resource group. At this time, there is no need to send information to indicate one or more subgroups for the second target resource group, which can reduce the total signaling overhead of the system.
[0277] In some embodiments, the terminal device receives third configuration information sent by the network device, where the third configuration information is used to indicate one or more second subgroups corresponding to the second target resource group, and the resources included in the second subgroups belong to the second target resource group.
[0278] At this time, the network device sends third configuration information to the terminal device, where the third configuration information is used to indicate one or more second subgroups corresponding to the second target resource group, and the resources included in the second subgroups belong to the second target resource group.
[0279] In an embodiment of the present application, the third configuration information is used to indicate multiple corresponding subgroups for a resource group in the second set, wherein the resource group in the second set is called the second resource group, and the second resource group targeted by the third configuration information is called the second target resource group.
[0280] The terminal device receives third configuration information sent by the network device, wherein the third configuration information indicates one or more second subgroups (subsets) for the second target resource group, and the resources in the second subgroup are referred to as second resources. The second target resource group belongs to a second resource group among the one or more second resource groups in the second set, the second subgroup can be understood as a subgroup corresponding to the second resource group, and the second resources contained in each of the one or more second subgroups belong to the second target resource group.
[0281] In the embodiment of the present application, the network device configures multiple subgroups for the second target resource group, which can effectively reduce signaling overhead.
[0282] In one example, the second set G2 is indicated as having X3 = 2 resource groups, which are denoted as G2_S1 and G2_S2, respectively. G2_S1 contains resources {B1, B2, B3, B4, B5, B6, B7, B8}. The third configuration information may indicate K3 subsets for resource group G2_S1. The first subset may include resources {B1, B2, B3, B4}. If a second subset is indicated, one example is that the second subset may include resources {B3, B4, B5, B6}, and another example is that the second subset may include resources {B5, B6, B7, B8}. In this case, resource group G2_S1 belongs to the first target resource group.
[0283] In some embodiments, the third configuration information is transmitted via RRC signaling.
[0284] In some embodiments, the third configuration information and the second configuration information are the same configuration information or two independent configuration information.
[0285] If the second configuration information and the third configuration information are the same configuration information, the one or more first subgroups configured for the first target resource group and the one or more second resource groups configured for the second target resource group are simultaneously indicated by the same configuration information, thereby reducing signaling overhead.
[0286] The second configuration information and the third configuration information are two independent and different configuration information, which can increase the flexibility of signaling and facilitate network optimization and implementation.
[0287] In some embodiments, if the third configuration information and the second configuration information are two independent configuration information, the third configuration information is further used to indicate the second target resource group.
[0288] When the third configuration information indicates the second target resource group, it can flexibly indicate for which second resource group the sub-group configuration is to be performed, thereby improving the flexibility of the system.
[0289] In the embodiment of the present application, if the third configuration information does not indicate the second target resource group, the second target resource group may be determined according to a predefined rule or based on the first target resource group.
[0290] In some embodiments, if the third configuration information and the second configuration information are two independent configuration information, the third configuration information and the second configuration information are transmitted in the same RRC information element.
[0291] In some embodiments, the third configuration information is further used to indicate a subgroup identifier of each second subgroup in one or more second subgroups corresponding to the second target resource group.
[0292] In some embodiments, the third configuration information indicates one or more second subgroups corresponding to the second target resource group in one of the following ways:
[0293] Indicating the resources included in the second subgroup in a bitmap manner;
[0294] For a second subgroup among the one or more second subgroups, indicate the number of the resource included in the second subgroup, where the number of the resource is the number of the resource in the second target resource group;
[0295] For a second subgroup among the one or more second subgroups, an identifier of a resource included in the second subgroup is indicated, where the identifier of the resource is an identifier in the resource configuration information of the resource.
[0296] In some embodiments, if the second set includes at least two first resource groups, the third configuration information is used to indicate a subgroup corresponding to each second resource group in the at least two second resource groups.
[0297] In the embodiment of the present application, the manner in which the third configuration information indicates the second subgroup can refer to the manner in which the second configuration information indicates the first subgroup, and will not be repeated here.
[0298] For the third target subgroup
[0299] In some embodiments, the first indication information is further used to indicate the third target subgroup; the third target subgroup is a third subgroup among the one or more third subgroups corresponding to the third target resource group.
[0300] In some embodiments, if the first indication information indicates the second serving cell and the first indication information indicates the third target subgroup, then the resources within the third target subgroup are in the second serving cell. In some embodiments, if the first indication information does not indicate the second serving cell and the first indication information indicates the third target subgroup, then the resources within the third target subgroup are in the first serving cell.
[0301] In some embodiments, if the first indication information indicates the second BWP and the first indication information indicates the third target subgroup, then the resources within the third target subgroup are within the second BWP. In some embodiments, if the first indication information does not indicate the second BWP and the first indication information indicates the third target subgroup, then the resources within the third target subgroup are within the first BWP.
[0302] In some embodiments, if the third target resource group corresponds to one or more third subgroups, and the first indication information does not indicate the third target subgroup, the third target subgroup is one of the following:
[0303] a third subgroup determined from the one or more third subgroups according to a third rule;
[0304] a third subgroup determined from the one or more third subgroups according to a third relationship, wherein the third relationship is a correspondence between the first subgroup in the first target resource group and the third subgroup in the third target resource group;
[0305] the third target resource group.
[0306] In some embodiments, if the third target resource group does not correspond to one or more third subgroups, the third target subgroup is one of the following:
[0307] a subgroup consisting of third resources determined from the third target resource group according to a fourth rule;
[0308] a subgroup consisting of third resources determined from the third target resource group according to a fourth relationship, wherein the fourth relationship is a correspondence between a first resource in the first target resource group and a third resource in the fourth target resource group configured by the network device;
[0309] the third target resource group.
[0310] In the embodiment of the present application, when the terminal device performs measurement and / or reporting based on the third target subgroup, the third target subgroup is determined in one of the following ways:
[0311] If the terminal device is configured with the third set and the first indication information indicates the third target subgroup, the terminal device also performs measurement and / or reporting based on the third target subgroup. In this case, that is, the terminal device performs measurement and / or reporting based on the first target subgroup and the third target subgroup.
[0312] If the terminal device is configured with a third set, and one or more subgroups are indicated for the third target resource group in the third set, but the first indication information does not indicate the third target subgroup corresponding to the third target resource group, the terminal device performs measurement and / or reporting based on the third target subgroup, and the third target subgroup is determined according to a predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the first subgroup of the first target resource group and the third subgroup of the third target resource group configured by the network (for example, the network indicates the correspondence through an RRC parameter), or the third target subgroup is the third target resource group. At this time, the first indication information does not need to indicate the third target subgroup, which can reduce the signaling overhead of the first indication information.
[0313] If the terminal device is configured with the third set, but one or more subgroups are not indicated for the third target resource group, the terminal device performs measurement and / or reporting based on the third target subgroup, and the third target subgroup is determined according to a predetermined rule (for example, a rule specified by the protocol), or is determined according to the correspondence between the first resource (or signal resource) of the first target resource group and the third resource (or signal resource) of the third target resource group configured by the network (for example, the network indicates the correspondence through an RRC parameter), or the third target subgroup is the third target resource group. At this time, there is no need to send information to indicate one or more subgroups for the third target resource group, which can reduce the total signaling overhead of the system.
[0314] It is understandable that if the terminal device is indicated with the second set and the third set, and the first indication information also indicates the second target subgroup and the third target subgroup, the terminal device performs measurement and / or reporting based on the first target subgroup, the second target subgroup and the third target subgroup.
[0315] In an embodiment of the present application, when the terminal device performs measurement and / or reporting based on the first target subgroup, the second target subgroup and the third target subgroup, the determination method of each subgroup in the first target subgroup, the second target subgroup and the third target subgroup can be independent of each other.
[0316] In some implementations, the terminal device receives fourth configuration information sent by the network device, where the fourth configuration information is used to indicate one or more third subgroups corresponding to the third target resource group, and resources included in the third subgroups belong to the third target resource group.
[0317] At this time, the network device sends fourth configuration information to the terminal device, where the fourth configuration information is used to indicate one or more third subgroups corresponding to the third target resource group, and the resources included in the third subgroups belong to the third target resource group.
[0318] In an embodiment of the present application, the fourth configuration information is used to indicate multiple corresponding subgroups for a resource group in the third set, wherein the resource group in the third set is called the third resource group, and the third resource group targeted by the fourth configuration information is called the third target resource group.
[0319] The terminal device receives fourth configuration information sent by the network device, wherein the fourth configuration information indicates one or more third subgroups (subsets) for the third target resource group, and resources in the third subgroup are referred to as third resources. The third target resource group belongs to one of the one or more third resource groups in the third set, and the third subgroup can be understood as a subgroup corresponding to the third resource group. The third resources contained in each of the one or more third subgroups belong to the third target resource group.
[0320] In the embodiment of the present application, the network device configures multiple subgroups for the third target resource group, which can effectively reduce signaling overhead.
[0321] In one example, the third set G3 is indicated with X4 = 2 resource groups, which are respectively denoted as G3_S1 and G3_S2, where G3_S1 contains resources {C1, C2, C3, C4, C5, C6, C7, C8}. The fourth configuration information may indicate K4 subgroups for resource group G3_S1. The first subgroup may include resources {C1, C2, C3, C4}. If a second subgroup is indicated, one example is that the second subgroup may include resources {C3, C4, C5, C6}, and another example is that the second subgroup may include resources {C5, C6, C7, C8}. In this case, resource group G3_S1 belongs to the third target resource group.
[0322] In some embodiments, the fourth configuration information is transmitted via RRC signaling.
[0323] In some embodiments, the fourth configuration information and the second configuration information are the same configuration information or two independent configuration information.
[0324] If the second configuration information and the fourth configuration information are the same configuration information, then the same configuration information is used to simultaneously indicate one or more first subgroups configured for the first target resource group and one or more third resource groups configured for the third target resource group, thereby reducing signaling overhead.
[0325] The second configuration information and the fourth configuration information are two independent and different configuration information, which can increase the flexibility of signaling and facilitate network optimization and implementation.
[0326] In some embodiments, if the fourth configuration information and the second configuration information are two independent configuration information, the fourth configuration information is further used to indicate the third target resource group.
[0327] When the fourth configuration information indicates the third target resource group, it can flexibly indicate for which third resource group the sub-group configuration is to be performed, thereby improving the flexibility of the system.
[0328] In the embodiment of the present application, if the fourth configuration information does not indicate the third target resource group, the third target resource group may be determined according to a predefined rule or based on the first target resource group.
[0329] In some embodiments, if the fourth configuration information and the second configuration information are two independent configuration information, the fourth configuration information and the second configuration information are transmitted in the same RRC information element.
[0330] In some embodiments, the fourth configuration information is further used to indicate a subgroup identifier of each third subgroup in one or more third subgroups corresponding to the third target resource group.
[0331] In some embodiments, the fourth configuration information indicates one or more third subgroups corresponding to the third target resource group in one of the following ways:
[0332] Indicating the resources included in the third subgroup by means of a bitmap;
[0333] For a third subgroup among the one or more third subgroups, indicating the number of the resource included in the third subgroup, where the number of the resource is the number of the resource in the third target resource group;
[0334] For a second subgroup in the one or more third subgroups, an identifier of a resource included in the third subgroup is indicated, where the identifier of the resource is an identifier in the resource configuration information of the resource.
[0335] In some embodiments, if the third set includes at least two third resource groups, the fourth configuration information is used to indicate a subgroup corresponding to each third resource group in the at least two third resource groups.
[0336] In the embodiment of the present application, the manner in which the fourth configuration information indicates the third subgroup may refer to the manner in which the second configuration information indicates the first subgroup, and will not be repeated here.
[0337] In some embodiments, the reporting type of the measurement results of the first target subgroup is applicable to one or more of the following:
[0338] Non-periodic reporting, periodic reporting and semi-continuous reporting.
[0339] In the embodiment of the present application, the reporting of the measurement result of the terminal device based on the first target subgroup is applicable to one or more of the following solutions:
[0340] Applicable Solution 1: Applicable to non-periodic reporting. Non-periodic reporting 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.
[0341] Applicable solution 2 is applicable to periodic reporting. Periodic reporting is relatively inflexible. Introducing flexible subgroup-based indications can improve system flexibility. At the same time, not using aperiodic and semi-continuous reporting can reduce network and terminal implementation complexity.
[0342] Applicable solution three is applicable to semi-continuous reporting. Compared with aperiodic reporting, semi-continuous reporting is relatively less flexible. Introducing flexible subgroup-based indication can improve system flexibility. At the same time, by not using aperiodic and periodic reporting, network and terminal implementation complexity can be reduced.
[0343] Applicable solution 4 is applicable to non-periodic reporting, periodic reporting, and semi-continuous reporting. Therefore, flexible indication based on subgroups is introduced for all reporting methods to improve system flexibility.
[0344] Applicable Solution 5 applies to periodic and semi-continuous reporting. Compared with aperiodic reporting, periodic and semi-continuous 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.
[0345] Below, the interference measurement related content in scenario 2 in which the terminal device measures and / or reports based on the first target resource group is described.
[0346] In some embodiments, the terminal device is further configured to perform the following processing:
[0347] The terminal device performs interference measurement based on the second target resource group and / or the third target resource group, the second target resource group is one of the one or more second resource groups included in the second set, the second resource in the second resource group is used to perform interference measurement on the signal corresponding to the second resource, the third target resource group is one of the one or more third resource groups included in the third set, and the third resource in the third resource group is used to perform interference measurement.
[0348] In the embodiment of the present application, when the terminal device measures and / or reports based on the first target resource:
[0349] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first target resource group and the second target resource group, and the terminal device does not receive the first indication information, the terminal device performs measurement and / or reporting based on the first target resource group and the second target resource group.
[0350] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first target resource group and the third target resource group, and the terminal device does not receive the first indication information, the terminal device performs measurement and / or reporting based on the first target resource group and the third target resource group.
[0351] Optionally, if the measurement and / or reporting of the terminal device corresponds to the first target resource group, the second target resource group and the third target resource group, and the terminal device does not receive the first indication information, the terminal device performs measurement and / or reporting based on the first target resource group, the second target resource group and the third target resource group.
[0352] In some embodiments, based on the method described in FIG3 , the method further includes:
[0353] The terminal device reports a first result to the network device, where the first result includes a measurement result of the measurement information and / or a prediction result corresponding to the measurement information, and the prediction result is determined based on the measurement result.
[0354] The measurement result may be a measurement result obtained by measuring based on the first target subgroup, or may be a measurement result obtained by measuring based on the first target resource group.
[0355] For the first result, include one or more of the following options:
[0356] Option 1: The first result includes a measurement result of the terminal device;
[0357] Option 2: The first result includes the prediction result of the terminal device;
[0358] Option 3: The first result includes the measurement result and prediction result of the terminal device.
[0359] For option 1, the terminal device performs measurements and reports the measurement results to the network device. The network device can 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 device can instruct 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.
[0360] For option 2, the terminal device performs measurements 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 device can assist the network device in better beam management and improve network performance.
[0361] Option three is a combination of options two and one. The measurement information measured by the terminal device itself may be more accurate than the predicted one. Reporting the measured information to the network can assist the network in making better beam management and improving network performance.
[0362] In the embodiment of the present application, the terminal device only determines the measurement result and reports the measurement result to the network device. When the terminal device determines the measurement result and determines the prediction result based on the measurement result, the first result reported is any one of the above options.
[0363] In some embodiments, if the terminal device determines the measurement result and the prediction result, the first result is the measurement result or the prediction result, and the method further includes:
[0364] The terminal device receives second indication information sent by the network device, where the second indication information is used to indicate that the first result is the measurement result or the prediction result.
[0365] The network device also performs the following processing:
[0366] The network device sends second indication information to the terminal device, where the second indication information is used to instruct the terminal device to determine the measurement result and the prediction result, and the first result is the measurement result or the prediction result.
[0367] The network device uses the second indication information to clarify whether the terminal device reports the prediction result or the measurement result, thereby providing greater freedom for the network.
[0368] The determination based on the second indication information may be based on the value of the second indication information. For example, when the second indication information is the second value, the first result includes the measurement result; and when the second indication information is the third value, the first result includes the prediction result.
[0369] In one example, when the second indication information is the second value, the first result includes the measured L1-RSRP corresponding to the signal or signal resource; when the second indication information is the third value, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource.
[0370] In an embodiment of the present application, the determination based on the second indication information can be based on whether the network has sent or configured the second indication information. For example, when the network device sends the second indication information, the first result includes the measurement result; when the network device does not send the second indication information, the first result includes the prediction result. For another example, when the network device sends the second indication information, the first result includes the prediction result; when the network device does not send the second indication information, the first result includes the measurement result.
[0371] In one example, when the network device does not send or indicate the second indication information, the first result includes the measured L1-RSRP corresponding to the signal or signal resource; when the network device sends or indicates the second indication information, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource.
[0372] In one example, when the network device does not send or indicate the second indication information, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource; when the network device sends or indicates the second indication information, the first result includes the measured L1-RSRP corresponding to the signal or signal resource.
[0373] In some embodiments, the measurement information includes one or more of the following:
[0374] Reference signal received power RSRP or layer 1 reference signal received power L1-RSRP;
[0375] Signal to Interference and Noise Ratio SINR or Layer 1 Signal to Interference and Noise Ratio L1-SINR.
[0376] In some embodiments, based on the method shown in FIG3 , the terminal device reports first capability information to the network device, where the first capability information is used to indicate a first terminal capability of the terminal device, and the first terminal capability is related to a subgroup.
[0377] Based on the method shown in FIG4 , the network device further performs the following processing:
[0378] The network device receives first capability information reported by the terminal device, where the first capability information is used to indicate a first terminal capability of the terminal device, and the first terminal capability is related to the subgroup.
[0379] In an embodiment of the present application, the terminal device reports a first terminal capability to the network device, where the first terminal capability indicates all or part of the subgroup-related capabilities of the first terminal device.
[0380] In some embodiments, the first capability information is transmitted via RRC signaling or MAC CE.
[0381] In some embodiments, the first terminal capability includes one or more of the following:
[0382] For a resource group, one or more corresponding subgroups are configured through RRC;
[0383] For a resource group, the MAC CE indicates the corresponding one or more subgroups;
[0384] For a resource group, the DCI indicates the corresponding one or more subgroups;
[0385] The terminal device supports subgroup-based measurement and / or reporting.
[0386] In an embodiment of the present application, the first terminal capability may include: 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.
[0387] In some embodiments, the first terminal capability is reported according to one of the following:
[0388] Frequency band, frequency band combination, frequency band in a frequency band combination, carrier on a frequency band in a frequency band combination, frequency band range, and terminal equipment.
[0389] The first terminal capability is reported per band, which can be understood as either reporting the first terminal capability for each band or reporting the corresponding capability independently for different bands. Independent reporting of different bands allows for greater flexibility in terminal device implementation. For example, a terminal device can support a feature on one or more bands but not on other bands, allowing more terminals to support this new feature.
[0390] The first terminal capability is reported per band combination, which can be understood as the first terminal capability being reported independently per band combination. Independent reporting of different band combinations allows for greater flexibility in terminal device implementation. For example, a terminal device may not support a feature under one band combination but support it under another, allowing more terminal devices to support the new feature.
[0391] The first terminal capability is reported per band per band combination, which can be understood as the first terminal capability being reported independently for each band in the band combination or for bands in different band combinations. Independent reporting of different band combinations allows terminal devices to have greater freedom in implementation. For example, a terminal device may not support a certain function under a certain CA, but may support this function on certain bands under another CA combination, thereby allowing more terminals to support this new function.
[0392] The first terminal capability is reported per carrier per CC per band per band combination (or FSPC) in the frequency band combination. This means that the first terminal capability is reported independently per carrier per frequency band in the frequency band combination, or that different carrier CCs in frequency bands in different frequency band combinations can be reported independently. Independent reporting of different frequency band combinations, and independent reporting of different carriers on a band, allows terminal devices to have greater freedom, allowing more terminal devices to support this new feature.
[0393] The first terminal capabilities are reported per frequency range, which can be understood as either reporting the first terminal capabilities per frequency range (FR), or reporting them independently for different FRs, or reporting them independently for FR1 and FR2. Independent reporting for different FRs allows greater flexibility for terminal device implementation. For example, a terminal device may not support a feature in its low frequency (FR1) but may support it in FR2 (high frequency), allowing more terminals to support this new feature.
[0394] The first terminal capability is reported per UE, which can be understood as reporting the first terminal capability for the UE. That is, if the UE reports this capability, it can be supported on all frequency bands, which can reduce the signaling overhead of terminal capability reporting.
[0395] The first configuration information is further described below.
[0396] In some embodiments, the first configuration information is associated with a first serving cell.
[0397] The first configuration information being associated with the first serving cell can be understood as the first configuration information belonging to the first serving cell, that is, the first configuration information is configuration information of the first serving cell or the first configuration information is transmitted via the first serving cell. The first serving cell can be a serving cell accessed by the terminal device.
[0398] In some embodiments, the resources in the one or more first resource groups in the first set belong to the first serving cell or the second serving cell.
[0399] If the resources in one or more first resource groups in the first set belong to the first service cell, the first configuration information and the resources configured by the first configuration information are in the same service cell, which can effectively reduce the processing complexity of the system (including UE), thereby reducing the difficulty of product implementation.
[0400] If the resources in one or more first resource groups in the first set belong to the second service cell, the first configuration information and the resources configured by the first configuration information are in different service cells, the system flexibility can be increased, that is, the terminal device can measure the resources of other cells, and then report the measurement results from another cell, thereby improving the overall performance of the system.
[0401] In some examples, one resource in the first resource group corresponds to one signal.
[0402] Each first resource in each first resource group in the one or more first resource groups in the first set corresponds to a signal, or a reference signal, or a reference signal resource.
[0403] In some embodiments, each of the one or more resource groups in the first set may indicate one or more CSI-RS resources, or may indicate one or more SSBs, or may indicate both CSI-RS resource(s) and SSB(s).
[0404] In some embodiments, for the NR system, a resource group in the first set indicates a CSI-RS resource, then the field "repetition" in the RRC signaling corresponding to the configuration of the resource group may have a value of "on" or "off", that is, performing repeated transmission or not performing repeated transmission.
[0405] In some embodiments, the first configuration information is also used to configure a second set and / or a third set, the second set includes one or more second resource groups, the third set includes one or more third resource groups, the second resources in the second resource group are used to perform interference measurement on the signal corresponding to the second resource, and the third resources in the third resource group are used to perform interference measurement.
[0406] In an embodiment of the present application, the resource group in the first set can be called the first resource group and the resources in the first set can be called the first resources, the resource group in the second set can be called the second resource group and the resources in the second set can be called the second resources, and the resource group in the third set can be called the third resource group and the resources in the third set can be called the third resources.
[0407] The second set includes one or more second resource groups. The second 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).
[0408] Each resource group in the second set is used for interference measurement (interference measurement), that is, resources in one or more resource groups in the second set, or reference signals (or reference signal resources) are used for interference measurement.
[0409] The third set includes one or more third resource groups. The third resource in the third set may correspond to a frequency domain resource, or a time domain resource, or a time domain-frequency domain resource.
[0410] In an embodiment of the present application, when the first configuration information indicates both the first set and the second set, the terminal device can, according to the network configuration information, perform channel measurement based on one or more resource groups in the first set, and perform interference measurement based on the corresponding one or more resource groups in the second set. The first terminal device then determines what to report to the network based on these measurement results. In this case, the terminal device can directly measure the beams of other interference, thereby more accurately obtaining communication quality information and improving overall system performance.
[0411] In an embodiment of the present application, when the first configuration information indicates both the first set and the third set, the terminal device can, based on the network configuration information, perform channel measurement based on one or more first resource groups in the first set, and perform interference measurement based on one or more corresponding third resource groups in the third set. The terminal device then determines what to report to the network device based on these measurement results. The terminal device can measure the overall interference situation of other cells or other beams, thereby more accurately obtaining communication quality information and improving overall system performance.
[0412] In an embodiment of the present application, 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 first resource groups in the first set, perform interference measurement based on one or more corresponding second resource groups in the second set, and perform interference measurement based on one or more corresponding third resource groups in the third set according to the network configuration information. The terminal device then determines the report to the network device based on these measurement results. The terminal device 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, thereby obtaining communication quality information more accurately and improving the overall performance of the system.
[0413] In some embodiments, the second resources in one or more second resource groups in the second set belong to the first serving cell or the second serving cell or the third serving cell.
[0414] If the second resource belongs to the first serving cell, the first configuration information configures resources in the same cell. In this case, the first resource, the second resource, and the third resource may belong to the same serving cell. If the configuration information and the resources configured by the configuration information are in the same serving cell, the processing complexity of the system (including the UE) can be effectively reduced, thereby reducing the difficulty of product implementation.
[0415] If the second resource belongs to the second or third serving cell, the first configuration information configures resources in other cells for the second set. This increases system flexibility, allowing the UE to measure resources (e.g., signal resources) in other cells and then report the measurement results from that other cell, thereby improving overall system performance. If the second resource belongs to the second serving cell, the resources used for channel / beam measurement and interference measurement belong to the same cell, which can better reflect communication quality.
[0416] In some embodiments, one second resource in the second resource group corresponds to one signal.
[0417] The second resource in the second set corresponds to a signal (or a reference signal resource or a reference signal), and the first configuration information may indicate part or all of the following corresponding information:
[0418] Type of signal / reference signal
[0419] Signal / reference signal identification or number
[0420] Resources corresponding to the signal / reference signal (e.g., frequency domain resources, time domain resources, or time-frequency domain resources)
[0421] Power information corresponding to the signal / reference signal
[0422] Scrambling information corresponding to the signal / reference signal, for example, the scrambling information is used to generate the signal / reference signal sequence

[0424] Optionally, each of the one or more second resource groups in the second set may indicate one or more CSI-RS resources. Optionally, the second resource group may indicate a group of CSI-RS resources using a SEQUENCE structure.
[0425] In some embodiments, a third resource group in the third set indicates one or more of the following: time domain resources, frequency domain resources, and time-frequency resources.
[0426] For the third resource in the third set, the first configuration information may indicate part or all of the following corresponding information:
[0427] The resource's identifier, or number;
[0428] Resources corresponding to the signal / reference signal (such as frequency domain resources, time domain resources, or time domain-frequency domain resources).
[0429] If the first configuration information indicates resources corresponding to the signal or reference signal, the first configuration information may indicate one or more of the following information: corresponding subcarrier position, corresponding symbol position, occupied PRB resources, period, and offset.
[0430] In the embodiment of the present application, the time-frequency resources may be configured by CSI interference management (IM) resources (CSI-IM resources).
[0431] In some embodiments, the third resource group in the third set and the corresponding first resource group in the first set belong to the same serving cell, and the resources for measuring channels / beams and measuring interference belong to the same cell, which can better reflect the communication quality.
[0432] In some embodiments, the first configuration information is transmitted via RRC.
[0433] In some embodiments, the first configuration information is further used to instruct reporting of one of the following measurement information:
[0434] L1-RSRP or RSRP;
[0435] L1-SINR or SINR.
[0436] In some embodiments, the first configuration information is further used to indicate whether the reporting type is aperiodic reporting, periodic reporting, or semi-continuous reporting.
[0437] The terminal device can report the first result based on the reporting type indicated by the first configuration information.
[0438] The wireless communication method provided in the embodiments of the present application can be implemented in one or more of the following scenarios, including but not limited to:

[0457] In scenario C, when the terminal device performs measurements based on the first target subgroup in scenarios A and B, the terminal device performs interference measurements based on the second target subgroup and / or the third target subgroup corresponding to the first target subgroup, thereby improving the accuracy of the measurement results obtained based on the first target subgroup.
[0458] In related technologies, a terminal device performs measurements and / or reports based on the corresponding resource group according to the configuration and / or indication information (e.g., RRC, or RRC+DCI) of a network device. The wireless communication method provided in an embodiment of the present application, on this basis, can further enable the terminal device to perform measurements and / or reports based on one or more subgroups corresponding to the corresponding resource group according to the network configuration information and / or indication information.
[0459] The following further describes the wireless communication method provided in the embodiments of the present application.
[0460] In the following description, for simplicity, the reference to RS can refer to the transmitted RS itself or the resource corresponding to the RS. For example, the reference to CSI-RS can refer to CSI-RS resource. Similarly, the reference to CSI-IM can also refer to CSI-IM resource.
[0461] The wireless communication method provided in the embodiments of the present application includes but is not limited to the following aspects:
[0462] 1. A first terminal device receives first configuration information sent by a first network device. The first configuration information indicates a first set, which includes one or more resource groups (sets), which may also be called signal resource groups (Signal Resource Sets) or interference signal resource groups (Reference Signal Resource Sets). For the first configuration information:

For serving cell B: Optionally, serving cell A and serving cell B are the same serving cell. In this case, the configuration information and the resources are in the same serving cell, which can effectively reduce the processing complexity of the system and thus reduce the difficulty of product implementation; Optionally, serving cell A and serving cell B are different serving cells. In this case, the system flexibility can be increased, that is, the UE can measure the resources (e.g., signal resources) of other cells and then report the measurement results from the other cell, thereby improving the overall system performance.
[0466] d. Optionally, each resource in one or more resource groups in the first set corresponds to a signal, or a reference signal, or a reference signal resource.
[0467] e. Optionally, each of the one or more resource groups in the first set may indicate one or more CSI-RS resources, or may indicate one or more SSBs, or may indicate both CSI-RS resource (one or more) and SSB (one or more). Optionally, each resource group is used for channel measurement, or for beam measurement, or for both channel measurement and beam measurement; optionally, for the NR system, if one of the above resource groups indicates a CSI-RS resource, the field "repetition" in the RRC signaling corresponding to the signal group configuration may have a value of "on" or "off".
[0468] f. Optionally, the first configuration information indicates reporting of L1-RSRP, or L1-SINR, or RSRP, or SINR, thereby combining with 5G system design.
[0469] i. Optionally, for the NR system, the first configuration information may carry a domain or field (field) "report quality (reportQuantity)", whose value may be cri-RSRP, or ssb-Index-RSRP, or cri-SINR, or ssb-Index-SINR.
[0470] g, Optionally, the first configuration information indicates a second set, the second set including one or more resource groups; the resource groups in the first set and the second set are different.
[0471] i. Optionally, the resources in one or more resource groups in the second set belong to serving cell C, that is, the resources in one or more resource groups in the second set are resources in serving cell C. Optionally, serving cell A and serving cell C are the same serving cell; Optionally, serving cell A and serving cell C are not the same serving cell; Optionally, serving cell B and serving cell C are the same serving cell;
[0472] ii. Optionally, each resource in one or more resource groups in the second set corresponds to a signal, or a reference signal, or a reference signal resource;
[0473] iii. Optionally, each of the one or more resource groups in the second set may indicate one or more CSI-RS resources, or may indicate one or more SSBs, or may indicate both CSI-RS resources (one or more) and SSBs (one or more);
[0474] iv. Optionally, resources in one or more resource groups in the second set are used for interference measurement.
[0475] h. Optionally, the first configuration information indicates a third set, the third set including one or more resource groups; the resources in the third set do not actually correspond to actual transmitted signals. Optionally, each of the one or more resource groups in the third set indicates one or more time-domain resources, frequency-domain resources, or time-frequency resources; optionally, the time-frequency resources may be configured as CSI-IM resources; optionally, the resources in the one or more resource groups in the third set are used for interference measurement.
[0476] i. Optionally, the first configuration information indicates that the corresponding reporting type is periodic, non-periodic, or semi-continuous.
[0477] j. Optionally, the first configuration information indicates the first set, or indicates the first set and the second set at the same time, or indicates the first set and the third set at the same time, or indicates the first set, the second set and the third set at the same time.
[0478] k. The first terminal device can receive multiple first configuration information sent by the first network device; optionally, multiple first configuration information can be transmitted in the same RRC IE.
[0479] 2. Based on 1, the first terminal device receives second configuration information sent by the first network device. The second configuration information indicates one or more subgroups (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 the resources (or signal resources) contained in each of the one or more subgroups belong to the resources in the first resource group. Here, compared with configuring multiple groups, configuring multiple subgroups for a certain group can effectively reduce the overhead of RRC signaling. For the second configuration information:
[0480] a. Optionally, the second configuration information is transmitted via RRC signaling.
[0481] b. Optionally, the first configuration information and the second configuration information are the same configuration information, thereby reducing signaling overhead.
[0482] c. Optionally, the first configuration information and the second configuration information are different configuration information, thereby increasing signaling flexibility and facilitating network optimization. i. Optionally, the second configuration information also indicates the first resource group, allowing for flexible indication of which resource group to use, thereby increasing system flexibility; ii. Optionally, the first configuration information and the second configuration information are transmitted in the same RRC IE.
[0483] d. Optionally, for a subgroup in one or more subgroups, the second configuration information indicates an identifier of the corresponding subgroup, so as to facilitate subsequent signaling to indicate the corresponding subgroup.
[0484] e. Optionally, each subgroup in one or more subgroups indicates which resources in the first resource group belong to this subgroup by means of a bitmap. Compared with f, 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.
[0485] f. Optionally, each subgroup in one or more subgroups indicates which resources in the first resource group belong to this subgroup by indicating one or more numbers, wherein the numbers are numbers of 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. Compared with e, 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.
[0486] g. Optionally, each subgroup in 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. Directly using the identifier of the CSI-RS resource itself can simplify UE processing. The disadvantage is that it may increase the overhead of RRC signaling.
[0487] h. Optionally, the second configuration information may indicate subgroups corresponding to multiple first resource groups.
[0488] In the embodiment of the present application, the configuration of the subgroup of the first resource group in the first set can be extended to the configuration of the subgroup of the second resource group in the second set and the third resource group in the third set.
[0489] For example, i, the third configuration information is used to indicate one or more subgroups for the second resource group, wherein the second resource group belongs to a 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.
[0490] For example ii, the fourth configuration information is 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, wherein the resources in the third resource group, i.e., the third resources, are not signal resources.
[0491] For the third and fourth configuration information:
[0492] Optionally, the third configuration information and the second configuration information are the same configuration information.
[0493] Optionally, the fourth configuration information and the second configuration information are the same configuration information.
[0494] Optionally, the third configuration information, the fourth configuration information and the second configuration information are the same configuration information.
[0495] 3. Optionally, based on 2, the first terminal device receives first indication information sent by the first network device, where the first indication information indicates a first subgroup corresponding to the first resource group, and the first subgroup belongs to a subgroup of one or more subgroups corresponding to the first resource group. Thus, through the first indication information, it is possible to flexibly indicate which subgroup or subgroups to use, thereby reducing signaling overhead and improving system performance. The first indication information here is transmitted via RRC or MAC CE. For the first indication information transmitted via RRC or MAC CE:
[0496] a. Optionally, the first indication information also indicates a second subgroup corresponding to the second resource group, and the second subgroup belongs to a subgroup among one or more subgroups corresponding to the second resource group, so that the corresponding interference measurement subgroup can be flexibly indicated at the same time in the same signaling, which increases the system flexibility on the one hand and does not significantly increase the signaling overhead on the other hand.
[0497] b. Optionally, the first indication information indicates a third subgroup corresponding to the third resource group, and the third subgroup belongs to a subgroup among one or more subgroups corresponding to the third resource group, so that the corresponding interference measurement subgroup can be flexibly indicated at the same time in the same signaling, which increases the system flexibility on the one hand and does not significantly increase the signaling overhead on the other hand.
[0498] c. Optionally, the first indication information is transmitted through RRC signaling. Using RRC signaling has a simple design and high reliability, but the disadvantages are large signaling overhead and long processing delay.
[0499] d. Optionally, the first indication information is transmitted through MAC CE. Compared with RRC signaling, MAC CE signaling has low overhead, low processing delay, and better reliability than DCI signaling, and can achieve a better compromise and balance among multiple system design indicators.
[0500] i. Optionally, the first indication information indicates a first serving cell or carrier, and the first indication information applies to the first serving cell or the MAC CE applies to the first serving cell or (indicates the Serving Cell for which the MAC CE applies); optionally, the first serving cell is indicated by a serving cell ID (Serving Cell ID).
[0501] ii. Optionally, the first indication information indicates a first BWP, and the first indication information applies to the first BWP or the MAC CE applies to the first serving cell (indicates the BWP for which the MAC CE applies); optionally, the first BWP is indicated by a BWP ID.
[0502] iii. Optionally, the first indication information indicates a second serving cell or carrier, and the resources (or signal resources) in the first subgroup are in the second serving cell or belong to the second serving cell, and can flexibly indicate the signals / resources measured in other cells; wherein, optionally, the second serving cell is indicated by a serving cell ID (Serving Cell ID); optionally, if the first indication information also indicates a second subgroup, the resources (or signal resources) in the second subgroup are in the second serving cell; optionally, if the first indication information also indicates a third subgroup, the resources in the third subgroup are in the second serving cell.
[0503] iv. Optionally, if the second service cell is not indicated, the resources (or signal resources) within the first subgroup are in the first service cell, thereby reducing signaling overhead, but cannot indicate the measured signals of other cells / carriers; optionally, if the first indication information also indicates a second subgroup, the resources (or signal resources) within the second subgroup are in the first service cell; optionally, if the first indication information also indicates a third subgroup, the resources within the third subgroup are in the first service cell.
[0504] v. Optionally, the first indication information indicates a second BWP, and the resources (or signal resources) within the first subgroup are in the second BWP (or belong to the second BWP), and can flexibly indicate the signals / resources measured by other BWPs; optionally, the second BWP is indicated by the BWP ID; optionally, if the first indication information also indicates a second subgroup, the resources (or signal resources) within the second subgroup are in the second BWP; optionally, if the first indication information also indicates a third subgroup, the resources within the third subgroup are in the second BWP.
[0505] vi. Optionally, if the second BWP is not indicated, the resources (or signal resources) in the first subgroup are in the first BWP, which can reduce signaling overhead. However, the measured signals of other BWPs cannot be indicated. Optionally, if the first indication information also indicates a second subgroup, the resource signals (or signal resources) in the second subgroup are in the first BWP. Optionally, if the first indication information also indicates a third subgroup, the resources in the third subgroup are in the first BWP.
[0506] vii. Optionally, the above solution applies to aperiodic reporting. Aperiodic reporting 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.
[0507] viii. Optionally, the above solution is applicable to the case of periodic reporting. Among them, periodic reporting is relatively inflexible. Introducing flexible indication based on subgroups can improve system flexibility. At the same time, if non-periodic and semi-continuous reporting are not adopted, the complexity of network and terminal implementation can be reduced.
[0508] 1x. Optional: The above solution applies to semi-continuous reporting. Compared to aperiodic reporting, semi-continuous reporting is less flexible. Introducing flexible subgroup-based indications can improve system flexibility. By omitting both aperiodic and periodic reporting, network and terminal implementation complexity can be reduced.
[0509] x. Optionally, the above solution is applicable to non-periodic reporting, periodic reporting and semi-continuous reporting. Introducing flexible sub-group-based indications for all reporting methods can improve system flexibility.
[0510] xi. Optional: The above solution applies to periodic and semi-continuous reporting. Compared with aperiodic reporting, periodic and semi-continuous reporting are less flexible. Introducing flexible subgroup-based indications can improve system flexibility. Meanwhile, not using aperiodic reporting can reduce network and terminal implementation complexity.
[0511] 4. Based on 3, optionally, if the measurement and / or reporting of the first terminal device (or a certain measurement or reporting, which are similar and not described in detail below) corresponds to the first resource group, the first terminal device performs measurement and / or reporting based on the first subgroup. In the case of measurement and reporting based on the first subgroup:
[0512] a. Optionally, if the first configuration information indicates a second set, and the first indication information also indicates a second subgroup, then based on the first subgroup, the first terminal device also performs measurements and / or reports based on the second subgroup, and can assist the system in making better beam selection by measuring the interference.
[0513] b. Optionally, if the first configuration information indicates a third set, and the first indication information also indicates a third subgroup, then based on the first subgroup, the first terminal device also performs measurements and / or reports based on the third subgroup, and can assist the system in making better beam selection by measuring the interference.
[0514] c. Optionally, if the first configuration information indicates a second set, and the third configuration information indicates one or more subgroups for the second resource group, but the first indication information does not indicate a second subgroup corresponding to the second resource group, then based on the first subgroup, the first terminal device also performs measurement and / or reporting based on the second subgroup. The second subgroup is determined according to predetermined rules (for example, rules 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 the signaling overhead of the first indication information.
[0515] d. Optionally, if the first configuration information indicates a second set, but there is no third configuration information to indicate one or more subgroups for the second resource group, then based on the first subgroup, the first terminal device also performs measurements and / or reports based on the second subgroup. The second subgroup is determined according to predetermined rules (for example, rules specified by the protocol), or determined according to the correspondence between the resources (or signal resources) of the first signal group and the resources (or signal resources) of the second signal group configured by the network (for example, the network indicates the correspondence through RRC parameters), or the second subgroup is the second resource group, so there is no need to send the third configuration information, which can reduce the total signaling overhead of the system.
[0516] e. Optionally, if the first configuration information indicates a third set, and the fourth configuration information indicates one or more subgroups for the third resource group, but the first indication information does not indicate a third subgroup corresponding to the third resource group, then based on the first subgroup, the first terminal device also performs measurement and / or reporting based on the third subgroup. The third subgroup is determined according to predetermined rules (for example, rules specified by the protocol), or is determined according to the correspondence between the subgroups of the first resource group and the subgroups 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, which can reduce the signaling overhead of the first indication information.
[0517] f. Optionally, if the first configuration information indicates a third set, but there is no fourth configuration information to indicate one or more subgroups for the third resource group, then based on the first subgroup, the first terminal device also performs measurements and / or reports based on the third subgroup. The third subgroup is determined according to predetermined rules (for example, rules specified by the protocol), or determined according to the correspondence between the resources (or signal resources) of the first resource group configured by the network and the resources of the third resource group (for example, the network indicates the correspondence through RRC parameters), or the third subgroup is the third resource group. At this time, there is no need to send the fourth configuration information, which can reduce the total signaling overhead of the system.
[0518] 5. Based on 2, optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group, and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group. Among them, the measurement and / or reporting is performed based on the first resource group itself, rather than based on its subgroup measurement and / or reporting. Thus, the default behavior when the UE does not receive the first indication information is defined, which can reduce additional signaling design. In the case of measurement and / or reporting based on the first resource group:
[0519] a. Optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group and the second resource group, and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group and the second resource group.
[0520] b. Optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group and the third resource group, and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group and the third resource group.
[0521] c. Optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group, the second resource group and the third resource group, and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group, the second resource group and the third resource group.
[0522] 6. Based on 2, optionally, the first terminal device receives first indication information sent by the first network device, where the first indication information indicates a first subgroup corresponding to the first resource group, and the first subgroup belongs to a subgroup of one or more subgroups corresponding to the first resource group, wherein the first indication information is indicated by DCI signaling. The DCI signaling processing delay is lower, allowing the UE to measure different subgroups faster. For the first indication information transmitted via DCI:
[0523] a. Optionally, if the measurement and / or reporting of the first terminal device corresponds to a first resource group, the first terminal device performs measurement and / or reporting based on the first subgroup.
[0524] b. Optionally, the first indication information indicates the first subgroup by indicating a subgroup identifier, wherein when the number of subgroups is large, the DCI signaling overhead can be reduced compared with the following scheme.
[0525] c. Optionally, the first indication information indicates the first subgroup in a bitmap manner. Compared with the above aspect, when the number of subgroups is small, the DCI signaling overhead can be reduced.
[0526] d. Optionally, the first indication information is indicated by the first field in the DCI signaling (which can be combined with the previous a and b). Among them, i. Optionally, if there are multiple resource groups (in the first set, or in the first set and the second set, or in the first set and the third set, or in the first set and the second set and the third set) with corresponding subgroups, the size of the first field is determined according to the first number, which is the maximum number of subgroups 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 M1, M2, and M3), which can reduce RRC signaling; ii. Optionally, the size of the first field is configured by the network, which can increase system flexibility.
[0527] Optionally, if the value of the first domain is greater than the number of subgroups corresponding to the first resource group, the indication of the first domain is ignored, or a subgroup is determined according to a predetermined rule (eg, RRC pre-configured, or pre-specified by the protocol).
[0528] e. Optionally, when the first indication information takes the first value, the first terminal device performs measurement and / or reporting based on the first resource group, wherein the first value may be a predetermined reserved value (Note: equivalent to a fallback mode, i.e., not using the subgroup but directly using the resource group).
[0529] f. Optionally, if the first configuration information indicates a second set, the first 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). The second subgroup is determined according to the second indication information, or the second subgroup is determined according to a 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). By measuring the interference, the system can be assisted in making a better selection of the beam.
[0530] g. Optionally, if the first configuration information indicates a third set, the first terminal device also performs measurements and / or reports based on the third subgroup, and the third subgroup is determined according to the second indication information, or the third subgroup is determined according to a 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). By measuring the interference, the system can be assisted in making a better selection of the beam.
[0531] h. Optional. The above solution is applicable to aperiodic reporting, which offers the highest flexibility. Adding flexible subgroup-based indications to this solution further enhances system flexibility. By omitting periodic and semi-continuous reporting, network and terminal implementation complexity can be reduced.
[0532] i. Optional. The above solution is applicable to periodic reporting. Periodic reporting is relatively inflexible. Introducing flexible subgroup-based indication can improve system flexibility. Meanwhile, not using aperiodic and semi-continuous reporting can reduce network and terminal implementation complexity.
[0533] j. Optional. The above solution applies to semi-continuous reporting. Compared with aperiodic reporting, semi-continuous reporting is less flexible. Introducing flexible subgroup-based indication can improve system flexibility. By not using both aperiodic and periodic reporting, network and terminal implementation complexity can be reduced.
[0534] k, optional, the above solution is applicable to non-periodic reporting, periodic reporting and semi-continuous reporting. Introducing and adding sub-group-based flexible indication to all reporting modes can improve system flexibility.
[0535] 1. Optional: The above solution is applicable to periodic and semi-continuous reporting. Compared with aperiodic reporting, periodic and semi-continuous reporting are less flexible. Introducing flexible subgroup-based indications can improve system flexibility. Meanwhile, by not using aperiodic reporting, network and terminal implementation complexity can be reduced.
[0536] 7. Based on 6, optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group. The measurement is performed based on the first resource group itself rather than its subgroup, thereby defining the default behavior when the UE does not receive the first indication information DCI, which can reduce additional signaling design.
[0537] a. Optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group and the second resource group, and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group and the second resource group.
[0538] b. Optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group and the third resource group, and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group and the third resource group.
[0539] c. Optionally, if the measurement and / or reporting of the first terminal device corresponds to the first resource group, the second resource group and the third resource group, and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group, the second resource group and the third resource group.
[0540] 8. Based on any one of 1 to 7, optionally, the first terminal device reports a first result to the network device. Optionally, the first result may include the following options:
[0541] a. 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, L1-SINR can also be used. The terminal performs measurements based on one or more subgroups and reports the measurement results to the network. The network 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 UE to perform beam measurements, or configuring some beams for the UE, or instructing the UE to use one or some beams for transmission. This improves the overall performance of the network.
[0542] b. Option 2: The first result includes the prediction result of the first terminal device, for example, the signal (or signal resource) predicted by the first terminal device. Optionally, the predicted signal / signal resource can be reported by an identifier (for convenience, we call it 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 first terminal device, wherein the predicted RSRP value corresponds to the predicted signal or signal resource. In addition to L1-RSRP, it can also be L1-SINR. Here: The terminal 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, which can assist the network in making better beam management and improving network performance.
[0543] c. Option three: It is a combination of options two and one. 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, 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 predetermined rule (the implementation method may be different methods such as protocol provisions or network 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 included. 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.
[0544] In the case where a signal or signal resource can have both corresponding measured L1-RSRP and predicted L1-RSRP:
[0545] i. 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, the L1-RSRP may be replaced with the L1-SINR to report more information to the network, thereby assisting the network in better beam management and improving network performance.
[0546] ii. 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. In other embodiments, the L1-RSRP here can also be replaced with the L1-SINR. 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 better beam management and improve network performance.
[0547] iii. 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. In other embodiments, the L1-RSRP here can also be replaced with L1-SINR. 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 perform better beam management and improve network performance.
[0548] iv. Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, it is determined based on the second 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 second indication information is sent by the first network device to the first terminal device. In other embodiments, the L1-RSRP here can also be replaced by L1-SINR. 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. Optionally, the determination based on the second indication information can be based on the value of the second indication information. Optionally, the determination based on the second indication information can be based on whether the network has sent or configured the second indication information, which can reduce signaling overhead.
[0549] 9. Based on any one of 1 to 8, optionally, before the above steps, the first terminal device reports the first terminal capability to the first network device, where the first terminal capability indicates all or part of the subgroup-related capabilities of the first 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. Reporting of the first terminal capability:
[0550] a. Optionally, the first terminal capability is transmitted via RRC signaling or MAC CE.
[0551] b. Optionally, the first terminal capability is reported per band (i.e., different frequency bands can independently report corresponding capabilities, per band). Independent reporting of different frequency bands allows terminals greater flexibility in implementation. For example, a terminal can support a feature on one or some bands but not on other bands, allowing more terminals to support this new feature.
[0552] c. Optionally, the first terminal capability is reported independently according to the frequency band combination (per band combination). Independent reporting of different frequency band combinations can allow the terminal to have greater freedom. For example, the terminal may not support this function under a certain frequency band combination, but support this function under another frequency band combination, thereby allowing more terminals to support this new function.
[0553] d. Optionally, the first terminal capability is reported independently for each band in a band combination (i.e., bands in different band combinations can be reported independently, per band per band combination). Independent reporting of different band combinations allows terminals greater flexibility in implementation. For example, a terminal may not support a feature under a certain CA, but support it on certain bands under another CA combination, allowing more terminals to support this new feature.
[0554] e. Optionally, the first terminal capability is reported independently per carrier on each band in a band combination (i.e., different carriers CCs in bands in different band combinations can be reported independently, per CC per band per band combination, or FSPC). Independent reporting of different band combinations, and independent reporting of different carriers on a band, allows terminals greater freedom of implementation, allowing more terminals to support this new feature.
[0555] f. Optionally, the first terminal capability is reported by frequency range (i.e., different FRs can be reported independently, per FR, i.e., FR1 and FR2 can each be reported independently). Independent reporting of different FRs allows terminals greater implementation flexibility. For example, a terminal may not support a certain feature in low frequency (FR1) but supports it in FR2 (high frequency), allowing more terminals to support this new feature.
[0556] g. Optionally, the first terminal capability is reported per UE (ie, per UE, meaning that if the UE reports this capability, this capability can be supported on all frequency bands), thereby reducing signaling overhead for reporting terminal capabilities.
[0557] The wireless communication methods provided in the embodiments of the present application include but are not limited to the following embodiments.
[0558] Embodiment 1: A scenario of RRC plus MAC CE, wherein RRC is used to configure a subset, and MAC CE is used to indicate which subset to activate.
[0559] Regarding the first configuration information indicating the first set
[0560] The first terminal device receives first configuration information sent by the first 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 resource may correspond to a signal (e.g., SSB), may correspond to a reference signal (e.g., CSI-RS), or may correspond to 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). For example, when the resource corresponds to a reference signal resource, or a reference signal, the first configuration information may indicate some or all of the following corresponding information (corresponding to the reference signal resource, or the reference signal information):
[0561] Type of signal / reference signal;
[0562] Signal / reference signal identification or number;
[0563] Resources corresponding to the signal / reference signal (e.g., frequency domain resources, time domain resources, or time-frequency domain resources);
[0564] Power information corresponding to the signal / reference signal;
[0565] Scrambling information corresponding to the signal / reference signal, for example, the scrambling information is used to generate a signal / reference signal sequence;
[0566] QCL information corresponding to the signal / reference signal, or TCI-state information.
[0567] Optionally, in the NR system, each resource group in the one or more resource groups in the first set may indicate one or more CSI-RS resources, or may indicate one or more SSBs, or may indicate both CSI-RS resources (one or more) and SSBs (one or more). Assuming that a resource group is marked as ResourceSet, a group of resources may be indicated by a SEQUENCE structure (a structure of RRC signaling), for example: sequence SEQUENCE (size (SIZE) of resource-related information (maximum number of resources in the group)). The resource-related information may indicate different options, for example: Option 1: the resource-related information indicates a CSI-RS resource, Option 2: the resource-related information indicates an SSB, Option 3: the resource-related information indicates an SSB or indicates a CSI-RS resource.
[0568] 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, and can simultaneously complete the precoding matrix indicator (PMI) and beam measurement, thereby reducing system overhead. It can also be said that the resources in one or more resource groups in the first set, or the reference signal (or reference signal resource) 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 group, 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 field "repetition" in the RRC signaling corresponding to the signal group configuration can have a value of "on" or "off".
[0569] 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.
[0570] 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 first 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).
[0571] About the second collection
[0572] Optionally, based on the first configuration information indicating the first set, 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).
[0573] 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.
[0574] 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):
[0575] Type of signal / reference signal
[0576] Signal / reference signal identification or number
[0577] Resources corresponding to the signal / reference signal (e.g., frequency domain resources, time domain resources, or time-frequency domain resources)
[0578] Power information corresponding to the signal / reference signal
[0579] Scrambling information corresponding to the signal / reference signal, for example, the scrambling information is used to generate the signal / reference signal sequence
[0580] QCL information corresponding to the signal / reference signal, or TCI-state information
[0581] 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).
[0582] 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 first terminal device may perform channel measurement based on one or more resource groups in the first set, and perform interference measurement based on one or more corresponding resource groups in the second set according to the network configuration information, and then the first terminal device determines to report to the network based on these measurement results (for example, an SINR result or an L1-SINR result may be reported).
[0583] About the third collection
[0584] Optionally, based on the first configuration information indicating the first set, the first configuration information may also 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.
[0585] For example, the first configuration information for the resources in the third set may indicate part or all of the following corresponding information:
[0586] The resource identifier or number
[0587] 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
[0588] 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.
[0589] Optionally, the first configuration information indicates the first set and the third set. For example, when the first configuration information indicates both the first set and the third set, the first terminal device may 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 third set, and then the first terminal device determines to report to the network based on these measurement results (for example, an SINR result or an L1-SINR result may be reported).
[0590] Optionally, the first configuration information indicates a first set, a second set, and a 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 first terminal device can, according to the network configuration information, perform channel measurement based on one or more resource groups in the first set, perform interference measurement based on one or more corresponding resource groups in the second set, and perform interference measurement based on one or more corresponding resource groups in the third set, and then the first terminal device determines to report to the network based on these measurement results (for example, it can report an SINR result or an L1-SINR result).
[0591] Other instructions about the first configuration information
[0592] Optionally, the first configuration information indicates that the corresponding reporting type is periodic (Periodic), aperiodic (Aperiodic), or semi-persistent (Semi-persistent).
[0593] Optionally, the first terminal device may receive multiple first configuration information sent by the first network device. In other words, the first network device may configure one of the following for the first terminal device:
[0594] Multiple first sets;
[0595] a plurality of first sets and a plurality of second sets;
[0596] a plurality of first sets and a second set;
[0597] Multiple first sets and multiple third sets (for example, one first configuration information indicates both a first set and a third set, and another first configuration information indicates only one first set. Other situations are similar and can be easily expanded similarly, so they are not listed one by one);
[0598] a plurality of first sets and a third set;
[0599] a plurality of first sets, a plurality of second sets, and a plurality of third sets;
[0600] Multiple first sets, one second set, and multiple third sets
[0601] Multiple first sets, multiple second sets, and one third set
[0602] A plurality of first sets, a second set, and a third set.
[0603] Optionally, the plurality of first configuration information may be transmitted in the same RRC signaling, which facilitates sharing of part of the information and reduces the overall signaling overhead.
[0604] Optionally, the plurality of first configuration information are transmitted in different RRC signalings. The signaling design is simple, and the network sends the configuration, which has better flexibility.
[0605] Optionally, the multiple first configuration information are the same configuration information. The same configuration information indicates more content, which facilitates sharing of part of the information, thereby reducing overall signaling overhead.
[0606] Optionally, the multiple first configuration information are different configuration information. Using different configuration information to indicate each can simplify the design of signaling and protocols. At the same time, when the network sends the corresponding configuration, it also has better flexibility.
[0607] Indication of a sub-group of the first resource group
[0608] Based on any of the foregoing, the first terminal device receives second configuration information sent by the first network device, and the second configuration information indicates one or more subgroups (subsets) for the first resource group (set), wherein the first resource group belongs to one of the one or more resource groups in the first set, and the resources (or reference signal resources) contained in each of the one or more subgroups belong to the resources in the first resource group.
[0609] The first configuration information and the second configuration information are the same configuration information.
[0610] In an example, the first configuration information is as follows: ResourceSetConfig {SetIndicator, SetOfResource, ListOfSubset, …}
[0611] Resource Set Configuration (ResourceSetConfig) configures a resource group (for example, a first resource group), which contains the following information (each sub-item is optional and not necessarily all included. That is, these sub-items are optional. At the same time, other sub-items can also be included. In addition, the order of these sub-items is not limited. These sub-items can also be called a field).
[0612] The group indicator (SetIndicator) indicates the identifier or number of this resource group.
[0613] The set of resources (SetOfResource) indicates the resources included in this resource group. For example, its specific content may be the configuration information of each corresponding resource, or the identifier or number of each corresponding resource.
[0614] The subgroup list (ListOfSubset) indicates one or more subgroups corresponding to this resource group. Exemplarily, each subgroup can indicate the contained resources through a bitmap. Exemplarily, each subgroup can indicate the contained resources through a resource identifier / number. Exemplarily, each subgroup can indicate the contained resources of the subgroup through the number of the resource within the resource group. Exemplarily, ListOfSubset can indicate one or more subgroups through a SEQUENCE structure. As an example, each element in the SEQUENCE structure is a subgroup. Optionally, each subgroup has its own corresponding identifier (i.e., its own corresponding subgroup identifier). As another example, each element in the SEQUENCE structure is a subgroup identifier, which is used to indicate the corresponding subgroup.
[0615] In the above example of the first configuration information, the type of each field is omitted for simplicity. For example, the full form for a field is xxx Type XXX, meaning that a field named xxx has a corresponding type of TypeXXX. In the above example and the following examples, the type is omitted for simplicity, and written directly as xxx. For example, SetIndicator Type SETINDICATOR is abbreviated to SetIndicator, and SetOfResource Type SETOFRESOURCE is abbreviated to SetOfResource.
[0616] The first network device may indicate multiple resource groups to the first terminal device. Exemplarily, this indication signaling may be implemented through a SEQUENCE structure, wherein each element in the SEQUENCE structure corresponds to the ResourceSetConfig in the above example.
[0617] Optionally, the first configuration information and the second configuration information are different configuration information. As an example, the second configuration information may also indicate the first resource group. As an example, the first configuration information and the second configuration information may be transmitted in the same RRC IE.
[0618] In an example, the first configuration information and the second configuration information are as follows: ResourceSetConfig { SetIndicator, SetOfResource, … (indicates that there may be other fields or other sub-items)} SubsetConf { ResourceSetIndicator, ListOfSubset, …}
[0619] ResourceSetConfig is used as the first configuration information to configure a resource group (for example, a first resource group), which includes the following information (each sub-item is optional and not necessarily all included. That is, these sub-items are optional. At the same time, other sub-items can also be included. In addition, the order of these sub-items is not limited.) These sub-items can also be called a field.
[0620] SetOfResource indicates the resources contained in this resource group. For example, its specific content can be the configuration information of each corresponding resource, or the identifier or number of each corresponding resource.
[0621] SubsetConf is used as the second configuration information to configure one or more subgroups corresponding to a resource group (for example, a first resource group). It contains the following information (each subitem is optional and not necessarily all subitems are included. That is, these subitems are optional. At the same time, other subitems can also be included. In addition, the order of these subitems is not limited. These subitems can also be called a field.)
[0622] ResourceSetIndicator indicates a resource group. If this sub-item does not exist, then the resource group corresponding to the sub-group indicated below is determined according to pre-set rules (such as protocol provisions, implementation agreement between the two parties, network configuration, etc.).
[0623] ListOfSubset indicates one or more subgroups corresponding to this resource group. Exemplarily, each subgroup can indicate the contained resources through a bitmap. Exemplarily, each subgroup can indicate the contained resources through a resource identifier / number. Exemplarily, each subgroup can indicate the contained resources through the number of the resource within the resource group.
[0624] Exemplarily, ListOfSubset can indicate one or more subgroups through a SEQUENCE structure. As an example, each element in the SEQUENCE structure is a subgroup. Optionally, each subgroup has its own corresponding identifier (i.e., its own corresponding subgroup identifier). As another example, each element in the SEQUENCE structure is a subgroup identifier for indicating the corresponding subgroup.
[0625] The first network device can indicate multiple resource groups and subgroups corresponding to one or more resource groups to the first terminal device. Exemplarily, this indication can be implemented by two SEQUENCE structures, where each element in one SEQUENCE structure corresponds to ResourceSetConfig in the above example, and each element in the other SEQUENCE structure corresponds to SubsetConf in the above example.
[0626] For the resource group configuration subgroups in the second and third sets, except for the following content, refer to the description of the configuration subgroups in the configuration group in the first set.
[0627] The first terminal device receives third configuration information sent by the first network device, where the third configuration information indicates one or more subgroups for a second resource group (set), where the second resource group belongs to one of the one or more resource groups in the second set, and resources (or reference signal resources) contained in each of the one or more subgroups belong to resources in the second resource group. The third configuration information, the subgroup indication of the second resource group, etc. can be obtained by similarly expanding upon the methods described above for the first configuration information and the subgroup indication of the first resource group, and are not further described herein.
[0628] The first terminal device receives fourth configuration information sent by the first network device, where the fourth configuration information indicates one or more subgroups for a third resource group (set), where the third resource group belongs to one of the one or more resource groups in the third set, and resources (or reference signal resources) contained in each of the one or more subgroups belong to resources in the third resource group. The fourth configuration information, the subgroup indication of the third resource group, etc. can be obtained by similar expansion according to the aforementioned first configuration information and the subgroup indication of the first resource group, and are not further described here.

[0630] Optionally, the first terminal device receives first indication information sent by the first network device, where the first indication information indicates a first subgroup corresponding to the first resource group, where the first subgroup belongs to a subgroup among one or more subgroups corresponding to the first resource group. Optionally, the first subgroup is activated and can be used for corresponding measurement and / or reporting on the first terminal device side.
[0631] The first indication information further indicates a second subgroup corresponding to the second resource group, where the second subgroup belongs to a subgroup of one or more subgroups corresponding to the second resource group. Optionally, the second subgroup is activated and can be used for measurement and / or reporting corresponding to the first terminal device side.
[0632] Optionally, the first indication information indicates a third subgroup corresponding to the third resource group, and the third subgroup belongs to a subgroup of one or more subgroups corresponding to the third resource group. Optionally, the third subgroup is activated and can be used for measurement and / or reporting corresponding to the first terminal device side.

[0717] Optionally, if the first configuration information indicates the second set and the third set, and the first indication information also indicates the second subgroup and the third subgroup, the first terminal device performs measurement and / or reporting based on the first subgroup, the second subgroup and the third subgroup.
[0718] Optionally, if the first configuration information indicates a second set, and the third configuration information indicates one or more subgroups for the second resource group, but the first indication information does not indicate a second subgroup corresponding to the second resource group, the first terminal device also performs measurement and / or reporting based on the second subgroup. The second subgroup is determined according to predetermined rules (for example, rules 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 resource group is the second subgroup.
[0719] Optionally, if the first configuration information indicates a second set, but there is no third configuration information to indicate one or more subgroups for the second resource group, the first terminal device also performs measurements and / or reports based on the second subgroup, and the second subgroup is determined according to predetermined rules (for example, rules specified by the protocol), or determined according to the correspondence between the resources (or signal resources) of the first signal group configured by the network and the resources (or signal resources) of the second signal group (for example, the network indicates the correspondence through RRC parameters), or the second resource group is the second subgroup.
[0720] Optionally, if the first configuration information indicates a third set, and the fourth configuration information indicates one or more subgroups for the third resource group, but the first indication information does not indicate a third subgroup corresponding to the third resource group, the first terminal device also needs to perform measurements and / or reports based on the third subgroup.

[0722] Default behavior of the first terminal device when the MAC CE does not activate the subgroup
[0723] If the measurement and / or reporting of the first terminal device corresponds to the first resource group and the first terminal device does not receive the first indication information, the first terminal device performs measurement and / or reporting based on the first resource group.

[0728] For details about the first configuration information indicating the first set, the second set, the third set, and the second configuration information, the third configuration information, and the fourth configuration information, please refer to Example 1.
[0729] Indicating the first subgroup based on the first indication information in the DCI
[0730] The first terminal device receives first indication information sent by the first network device, where the first indication information indicates a first subgroup corresponding to the first resource group, and the first subgroup belongs to a subgroup among one or more subgroups corresponding to the first resource group, wherein the first indication information is indicated through DCI signaling.
[0731] If the measurement and / or reporting (or a certain measurement and / or reporting) of the first terminal device corresponds to the first resource group, the first terminal device performs measurement and / or reporting based on the first subgroup.
[0732] Optionally, when the first indication information takes a first value, the first terminal device performs measurement and / or reporting based on the first resource group, wherein the first value may be a predetermined reserved value. Exemplarily, when the first field takes a first value, the first terminal device performs measurement and / or reporting based on the first resource group. For example, an example is a reserved value of 0 (Note: equivalent to a fallback mode, i.e., not using a subgroup but directly using a resource group)
[0733] Optionally, if the first configuration information indicates a second set, the first terminal device also performs measurements and / or reports based on the second subgroup, that is, the first terminal device performs measurements and / or reports based on the first subgroup and the second subgroup. The second subgroup is determined according to the first indication information, or the second subgroup is determined according to a 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).
[0734] Optionally, if the first configuration information indicates a third set, the first terminal device also performs measurement and / or reporting based on the third subgroup, that is, the first terminal device performs measurement and / or reporting based on the first subgroup and the third subgroup. The third subgroup is determined according to the first indication information, or the third subgroup is determined according to a 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).
[0735] Optionally, if the first configuration information indicates the second set and the third set, the first terminal device also performs measurement and / or reporting based on the second subgroup and the third subgroup, that is, the first terminal device performs measurement and / or reporting based on the first subgroup, the second subgroup and the third subgroup. The second subgroup and the third subgroup are determined according to the first indication information, or the second subgroup and the third subgroup are determined according to a predetermined rule, or the second subgroup and the third subgroup are 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).
[0736] Regarding the default behavior of the first terminal device when the first indication information is not received through DCI
[0737] If the measurement and / or reporting of the first terminal device corresponds to the first resource group, and the first terminal device does not receive the first indication information (or the first terminal device receives the first indication information with a specific value), the first terminal device performs measurement and / or reporting based on the first resource group. The specific value is a predetermined value (for example, a predetermined value of the protocol or a network configuration).
[0738] Regarding the reporting behavior of the first terminal device
[0739] The first terminal device reports a first result to the network device. Optionally, the first result may include the following options:
[0740] Option 1: The first result includes a measurement result, for example, a measured L1-RSRP, and / or a corresponding signal identifier or signal resource identifier (for example, one identifier indicates one CSI-RS resource, and for another example, the identifier indicates one SSB). For example, the first result may include K L1-RSRP measurement results. For another example, the first result may include K pairs, each of which has a signal indication information / identifier and a corresponding measured L1-RSRP. For example, the first result includes 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}. The number of pairs included in the first result may be 2, 5, 7, or other values set according to requirements.
[0741] 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 in front, or the corresponding CSI-RS resource indicator with a larger value is placed in front).
[0742] For option 1, 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 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 algorithm is not limited). For example, the network device can instruct 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.
[0743] Option 2: The first result includes the prediction result of the first terminal device, for example, the signal (or signal resource) predicted by the first terminal device. Optionally, the predicted signal / signal resource can be reported by an identifier, i.e., 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 first terminal device, wherein the predicted RSRP value corresponds to the predicted signal or signal resource.
[0744] 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). 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. In one 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}.
[0745] In one example, the first result includes 4 pairs (indicating both SSB and CSI-RS resources):
[0746] {CSI-RS resource indicator1, L1-RSRP1}, {SSB index2, L1-RSRP2}, {CSI-RS resource indicator3, L1-RSRP3}, {CSI-RS resource indicator4, L1-RSRP4}.
[0747] For option 2, the terminal device 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., with no specific restrictions) to determine which beams are most beneficial to it. Reporting these predicted beams to the network device can assist the network device in better beam management and improve network performance.
[0748] Option 3 is a combination of Option 2 and Option 1. That is, the first result includes both the measured L1-RSRP and the predicted L1-RSRP.
[0749] 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.
[0750] In one example, the first result contains four 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}. In one example, the first result contains four 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}. For flag1, flag2, flag3, and flag4, different values indicate whether it is measured L1-RSRP or predicted L1-RSRP.
[0751] Optionally, whether to report a measurement result or a prediction result is determined according to a predetermined rule (which may be implemented in a protocol or in a network configuration). For example, the position in the reported information indicates whether a certain L1-RSRP is a measurement result or a prediction result.
[0752] Optionally, in the first result, a signal or signal resource may have a corresponding measured L1-RSRP and a predicted L1-RSRP at the same time. As an example, the first result includes 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 it is a measured or predicted result. For example, the measured L1-RSRP is placed in front of the predicted L1-RSRP. For another example, the predicted L1-RSRP is placed in front of the measured L1-RSRP. For example, each L1-RSPR corresponds to an additional information to indicate whether it is measured or predicted.
[0753] 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 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 CSI-RS resource.
[0754] 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 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 CSI-RS resource.
[0755] Optionally, if a signal or signal resource has a corresponding measured L1-RSRP and a predicted L1-RSRP, determining, based on second indication information, whether the reported first result includes the measured L1-RSRP corresponding to the signal or signal resource, or includes the predicted L1-RSRP corresponding to the signal or signal resource. The second indication information is sent by the first network device to the first terminal device.
[0756] As an example, it can be determined based on the value of the second indication information. For example, when the second indication information is the second value, the first result includes the measured L1-RSRP corresponding to the one signal or signal resource. When the second indication information is the third value, the first result includes the predicted L1-RSRP corresponding to the one signal or signal resource.
[0757] As an example, determining based on the second indication information may be based on whether the network has sent or configured the second indication information. For example, when the network has not sent or indicated the second indication information, the first result includes the measured L1-RSRP corresponding to the signal or signal resource; when the network has sent or indicated the second indication information, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource. For another example, when the network has not sent or indicated the second indication information, the first result includes the predicted L1-RSRP corresponding to the signal or signal resource; when the network has sent or indicated the second indication information, the first result includes the measured L1-RSRP corresponding to the signal or signal resource.
[0758] 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.
[0759] In addition, in the first result reported by the terminal device, L1-RSRP may be further 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.
[0760] Optionally, in the first result reported by the terminal device, if the first result includes multiple L1-RSRPs (which may be measured or predicted), it may be reported in a differential manner, thereby reducing reporting overhead.
[0761] The terminal device can select appropriate algorithms or rules (such as deep learning algorithms, AI algorithms, machine learning algorithms, statistical algorithms, etc., the specific algorithms are 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.
[0762] The wireless communication method provided in the embodiments of the present application can be applied to one or more of the following situations, including but not limited to:
[0763] AI or MI (AI / ML-based) or AI-based beam management process;
[0764] AI / ML-based spatial domain beam prediction or AI-based spatial domain beam prediction; for example, using the measurement results of G wide beams to predict the best G2 narrow beams (i.e., Top-G2 narrow beams); or, for example, using the measurement results of G beams to predict the best G2 narrow beams among G3 beams (i.e., Top-G2 narrow beams), where G beams are part of G3 beams;
