[0022] Communication system

[0023] Figure 1 This is an example diagram of the system architecture of a communication system 100 applicable to embodiments of this application. The communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The terminal device 120 can access a network, such as a wireless network, through the network device 110. Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity; this application embodiment does not limit this.

[0024] It should be understood that the technical solutions of the embodiments of this application can be applied to various communication systems, such as: fifth-generation (5G) systems, new radio (NR), long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to future communication systems, such as sixth-generation mobile communication systems, satellite communication systems, and so on.

[0025] In this application embodiment, the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user apparatus. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. Terminal devices can also be mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes. Optionally, terminal devices can act as base stations. For example, a terminal device can act as a dispatching entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) systems. For instance, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.

[0026] In this embodiment, the network device can be a device used to communicate with a terminal device. The network device can be an access network device or a wireless access network device. For example, the network device can be a base station. The term "base station" can broadly encompass various names as follows, or can be replaced by names such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master station (MeNB), secondary station (SeNB), multi-standard wireless (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar entity, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. A base station can also be a mobile switching center, or an entity that performs base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or an entity that performs base station functions in future communication systems. A base station can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment. In some deployments, the network equipment may include a CU or a DU; or, the network equipment may include both a CU and a DU. Optionally, the base station may include an AAU.

[0027] Furthermore, base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0028] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0029] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform such as a cloud platform.

[0030] Channel state information (CSI) is crucial information used in wireless communication systems to describe channel conditions. Network devices can rely on CSI for optimizations such as beamforming and resource scheduling. Traditionally, CSI is obtained through reports from terminal devices. However, future CSI predictions may need to be based on AI / ML models to reduce signaling overhead. AI / ML model predictions of CSI depend on high-quality, multi-dimensional data input, requiring the acquisition of complete channel matrices (e.g., amplitude and / or phase), reference signal reception power (RSRP), delay spread, Doppler shift, and other physical layer parameters. Millimeter-wave bands require subwavelength-level spatial sampling, while large-scale multiple-input multiple-output (MIMO) scenarios require full-antenna-port measurement data. Strict time synchronization between network devices and terminal devices necessitates CSI data coverage for scenarios such as indoor environments (e.g., multipath reflections), dense urban areas (e.g., non-line-of-sight (NLOS)), and high-speed mobile environments (e.g., high-speed rail and / or vehicle-mounted). Continuous acquisition of mobile terminal trajectory, speed, and environmental change data (e.g., obstacle movement) is also necessary to capture the time-varying characteristics of the channel. Deep learning models typically require millions of CSI samples for training. It's necessary to correlate CSI data with environmental semantic labels (e.g., device location, occlusion material) to enhance model interpretability.

[0031] The 3GPP standard defines the CSI reporting format to ensure data compatibility across vendor equipment. Physical layer data collection has expanded from traditional narrowband CSI to include multi-dimensional parameters such as full-band channel response, multi-antenna ports (e.g., massive MIMO), delay spread, and Doppler shift.

[0032] When using AI / ML models for CSI prediction, the measurement results of the Channel State Information Reference Signal (CSI-RS) will be used by network devices or terminal devices. When the terminal device uses the measurement results (e.g., for model training) and the network device does not need to use the measurement results, the CSI data does not need to be reported. When the network device needs to use the CSI-RS measurement results, the terminal device needs to report the measurement results to the network device.

[0033] In 5G and future wireless communication systems, CSI prediction using AI / ML models can be categorized into terminal device-side models and network device-side models based on their deployment location. Terminal device-side models are deployed locally on the terminal device (e.g., on mobile phones or Internet of Things (IoT) terminals). Based on locally measured channel information, they directly predict future CSI (e.g., channel matrix, signal strength, etc.), reducing the frequency of CSI reporting to network devices and thus lowering uplink signaling overhead. Furthermore, local CSI prediction on the terminal device eliminates the need to wait for feedback from network devices, improving real-time performance. Additionally, sensitive data is not uploaded, enhancing privacy protection. Terminal devices can configure measurement resources (e.g., periodic CSI, P-CSI, or semi-persistent CSI, SP-CSI) using existing protocols (e.g., CSI-ReportConfig) to collect local channel data (e.g., reference signal received power, channel response, etc.). However, the data available to models on terminal devices is relatively limited, consisting only of data from the local perspective of the terminal device, which may affect prediction accuracy. Model updates still rely on data distribution from network devices.

[0034] Network-side models, deployed at base stations or the core network, can predict global or single-user CSI based on historical CSI data or environmental information (e.g., geographical location, service type) reported by multiple terminal devices. This optimizes resource allocation for multiple users, such as MIMO precoding and scheduling. Active prediction by network devices reduces the measurement frequency and burden on terminal devices, while also providing global channel information. Network devices can aggregate CSI data reported by multiple terminal devices using information such as device location, network topology, and service load, and train more complex models in the cloud or locally. Furthermore, network devices can use CSI prediction results to predict terminal channel information in large-scale MIMO beamforming to optimize the precoding matrix, and predict channel reciprocity during dynamic TDD configuration to adjust the uplink / downlink time slot ratio.

[0035] As mentioned earlier, when using AI / ML models for CSI prediction, the CSI-RS measurement results may be used by network devices or terminal devices. When a terminal device uses the measurement results and the network device does not need to use them, the CSI data does not need to be reported. However, when a network device needs to use the CSI-RS measurement results, the terminal device needs to report the CSI data to the network device. Therefore, in an AI / ML system, when a terminal device needs to train and infer the CSI prediction model, it needs to meet both the needs of model training and the needs of CSI reporting within a certain period of time.

[0036] Therefore, this application proposes that the terminal device receives first information sent by the network device. The first information is used by the terminal device to determine whether to report second information. Since the decision to report the second information is made through the configuration of the network device, unnecessary reporting by the terminal device is avoided, and the measurement operations of the terminal device for other purposes are not affected.

[0037] The following is combined with Figure 2 The embodiments of this application will be described in detail below.

[0038] Figure 2 This is a flowchart illustrating the communication method provided in an embodiment of this application. Figure 2 The method 200 shown can be performed by a terminal device and a network device. The terminal device may be, for example, a terminal device... Figure 1 The terminal device 120 shown may be, for example, a network device. Figure 1 The network device 110 shown is shown. Figure 2 The method 200 shown may include some or all of the following steps.

[0039] In step 210, the network device sends the first information to the terminal device.

[0040] In step 220, the terminal device receives the first information sent by the network device.

[0041] The first information is used by the terminal device to determine whether to report the second information, or in other words, the first information is used to instruct the terminal device whether to report the second information. Optionally, the second information includes information related to the signal (or channel) measurement results of the terminal device, such as CSI or beamforming measurement results. The second information can be generated by a model in the terminal device, such as a CSI prediction model or a beamforming prediction model.

[0042] The terminal device can determine whether to report the second information based on the first information sent by the network device. It should be noted that the terminal device's decision not to report the second information does not mean it will not perform signal measurements. The terminal device can still perform signal measurements normally and use the results to perform other internal functions, such as model training or monitoring. In other words, when the first information indicates that the terminal device does not need to report the second information, the terminal device can choose not to perform measurements and report, or it can perform measurements but not report them.

[0043] In other words, this configuration method, which uses the first information to instruct the terminal device not to report the second information, can be used in scenarios where the network device does not need to explicitly obtain CSI from the terminal device, but the terminal device still needs to utilize the signal measurement results internally. The terminal device can perform signal measurements based on the configured reference signal, but does not generate or report any related measurement results (or reports). The terminal device may need the measurement results to perform internal actions, such as model training or monitoring.

[0044] Taking CSI as an example, if the terminal device receives the first information, and the first information indicates that the terminal device should not report CSI (or, not generate a CSI report), the terminal device may still report CSI. Optionally, if the terminal device decides not to report CSI, it may still perform CSI measurements and use the CSI measurement data to perform other tasks, such as performing CSI measurements and using the CSI measurement data to train a CSI prediction model, but it may choose not to report CSI, for example, not to report the precoding matrix indicator (PMI), channel quality indicator (CQI), rank indication (RI), etc.

[0045] In some implementations, the second information includes CSI, while the first information is carried in the CSI reporting configuration (denoted as CSI-ReportConfig). For example, the first information can be carried in the first field of the CSI reporting configuration.

[0046] In some implementations, the first field can be an existing field in CSI-ReportConfig. For example, the first field can be a field in the CSI reporting configuration used to indicate the reporting parameters (denoted as `reportQuantity`). The `reportQuantity` field typically indicates the reported physical quantity (hereinafter referred to as the reporting parameter), including the type of CSI content (or physical quantity) that the terminal device needs to report. For example, this field can indicate one or more of the following reporting parameters: CQI, PMI, RI, and CSI-RS resource indicator (CRI), SSB index, Layer 1 indicator (denoted as `L1`), reference signal receiving power (RSRP), and PMI-related parameters (e.g., parameter i1, used to indicate the wideband PMI configuration for Type I codebooks). Here, the `reportQuantity` field in CSI-ReportConfig can be reused to indicate whether the terminal device needs to perform CSI reporting based on CSI-ReportConfig. In this way, once the terminal device determines that it will not report CSI based on the reportQuantity field, it can perform CSI measurement only (for example, based on the content of other fields in CSI-ReportConfig or agreed parameters) without reporting CSI.

[0047] For example, if the first field includes a first value, the first field indicates that the terminal device does not perform CSI reporting (or, in other words, disables the CSI reporting function); conversely, if the first field does not include a first value (e.g., if it includes reporting parameters configured by the network device), the first field indicates that the terminal device performs CSI reporting. The first value could be, for example, none. In this case, if the value of the reportQuantity field is none (i.e., reportQuantity = none), it means that the terminal device does not need to perform CSI reporting, but is allowed to perform CSI measurements (e.g., CSI measurements based on the parameters carried by the various fields in CSI-ReportConfig or agreed-upon parameters). The measurement results can be used, for example, to obtain training data for the model. If reportQuantity ≠ none (e.g., reportQuantity = cri-RI-PMI-CQI), it means that the terminal device needs to perform CSI reporting based on CSI-ReportConfig (e.g., based on the reporting parameters indicated by the reportQuantity field). This approach allows for better compatibility with traditional terminal devices, or lower-version terminal devices (e.g., R18 version). The system does not need to send CSI-ReportConfig separately for traditional terminal devices (e.g., lower-version terminal devices) and terminal devices supporting the technical solutions of this application, i.e., higher-version terminal devices (e.g., R19 version terminal devices). For example, when reportQuantity = none, if the terminal device is performing other tasks (e.g., in the model training phase), the terminal device may not perform CSI reporting. Furthermore, the terminal device may not perform CSI reporting and may not perform beam measurement-related reporting.

[0048] Alternatively, in some implementations, the first field can be a new field added to CSI-ReportConfig. For example, a new field added to CSI-ReportConfig for version R19 (e.g., denoted as reportQuantity-R19) indicates whether the terminal device needs to report CSI based on CSI-ReportConfig. This new field may include, for example, a 1-bit value. As an example, a 1-bit value indicates CSI reporting, and a 0-bit value indicates no CSI reporting; or, a 0-bit value indicates CSI reporting, and a 1-bit value indicates no CSI reporting. After determining that no CSI reporting is needed based on the new field, the terminal device can perform CSI measurements only (e.g., based on the contents of other fields in CSI-ReportConfig) without reporting CSI. The newly added field can clearly indicate whether the terminal device performs CSI reporting based on CSI-ReportConfig. It is applicable to terminal devices that support the technical solutions of the embodiments of this application (e.g., high-version terminal devices). When the new field indicates that the terminal device does not perform CSI reporting, the terminal device may not perform any CSI reporting.

[0049] If the first field is a field in CSI-ReportConfig used to indicate reported parameters (e.g., reportQuantity), the first information may optionally include a new value added to the field in CSI-ReportConfig used to indicate reported parameters (e.g., reportQuantity). This new value could be, for example, none-R19. For instance, the value of the reportQuantity field in CSI-ReportConfig used to indicate reported parameters may include none and reported parameters (e.g., physical quantities such as PMI, RI, CQI, RSRP, etc.), and may also include the new value none-R19. Here, reportQuantity = none can retain the same meaning as in version R18; for example, only beam-related information, such as only beam-related information (e.g., SSB / CSI-RS signal strength), is reported without reporting PMI, RI, CQI, etc. When reportQuantity = none - R19, the terminal device is instructed to report CSI. This is equivalent to giving the reportQuantity field in version R19 a new meaning by assigning a new value, that is, not reporting CSI. This includes not reporting CSI-related information (e.g., not reporting PMI, RI, CQI, etc.) and not reporting beam-related information (e.g., the signal strength of SSB / CSI-RS).

[0050] In the case where the first field is the `reportQuantity` field in `CSI-ReportConfig`, which indicates the reporting parameter, optionally, this first field is valid during the model's inference process. This model is, for example, a model used to generate CSI, i.e., a CSI prediction model. Optionally, the first field is invalid during the model's training process; that is, the terminal device can determine whether to report according to the indication of the first field based on its own operations.

[0051] For example, when a terminal device receives a CSI-ReportConfig from a network device, if the terminal device is currently performing model inference (or not model training), the reportQuantity field in the CSI-ReportConfig can be considered valid. The terminal device can perform corresponding operations based on the original meaning of the reportQuantity field in R18. For example, when reportQuantity = none, only beam-related information can be reported; when reportQuantity represents the corresponding reporting parameter (e.g., PMI, RI, CQI, etc.), CSI reporting can be performed based on that parameter. If the terminal device is currently performing model training, the reportQuantity field in the CSI-ReportConfig can be considered invalid. Optionally, when the first field is considered invalid, the terminal device does not need to report, for example, it does not need to perform CSI reporting.

[0052] When the first field is a new field added to CSI-ReportConfig, CSI-ReportConfig also includes a second field. This second field can be, for example, the field in CSI-ReportConfig used to indicate the reporting parameter, namely the `reportQuantity` field. For instance, the new field could be denoted as `reportQuantity-R19`, which differs from the original `reportQuantity` field in CSI-ReportConfig used to indicate the reporting parameter. In this embodiment, the first and second fields are valid at different times; that is, the effective time periods (or effective time windows) of the first and second fields are different. Alternatively, the first and second fields are valid simultaneously; that is, the effective time periods of the first and second fields are the same.

[0053] In the first case, where the effective time periods of the first field and the second field are different, the effective time period of the first field may optionally include the first time period during which the terminal device trains the model, which is a model used to generate the second information (e.g., a CSI prediction model or a beam prediction model); and / or the effective time period of the second field may include other time periods besides the first time period.

[0054] As an example, taking CSI as the second piece of information, when a terminal device receives CSI-ReportConfig, it can determine whether the first field (e.g., reportQuantity-R19) or the second field (e.g., reportQuantity-R18) in CSI-ReportConfig is valid at the current time based on its current status information (e.g., whether model training is in progress). That is, only one of the first and second fields is valid at the current time. Optionally, if the terminal device is currently training a model, the first field is considered valid, and the terminal device will not report CSI if the first field indicates that the terminal device will not report. If the terminal device is not training a model, the second field is considered valid, and the terminal device can report CSI based on the reporting parameters indicated by the second field.

[0055] In the second scenario, where both the first and second fields are valid, optionally, the reporting parameters indicated by the second field can also be used by the terminal device for model training. For example, when the terminal device receives CSI-ReportConfig, if it is performing model training, even if the first field in CSI-ReportConfig (e.g., reportQuantity-R19) indicates that the terminal device is not performing CSI reporting, the terminal device will still use the reporting parameters indicated by the second field as measurement parameters for CSI measurement, thereby performing CSI measurement to obtain training data for model training.

[0056] When a terminal device receives a first message instructing it not to report CSI, it may choose not to report within a specific time window. For example, during the process of performing CSI measurements and training a CSI prediction model based on the CSI measurement data, the terminal device may choose not to report CSI within the time window corresponding to the CSI measurement and / or model training. Optionally, after model training is completed, the terminal device may report CSI independently or based on instructions from the network device. The reported CSI data may be the CSI data obtained within that time window. For example, the terminal device may report the CSI data used for model training to the network device, or it may re-perform CSI measurements and report the newly obtained CSI data to the network device.

[0057] In some implementations, the network device can send third information to the terminal device. Correspondingly, the terminal device receives the third information sent by the network device. This third information, for example, is used to indicate a change in the content indicated by the first information, or in other words, the third information is used to switch the content indicated by the first information. The content indicated by the first information includes reporting second information and / or not reporting second information. For example, the third information can be used to switch the content indicated by the first information from reporting second information to not reporting second information; or, for example, the third information can be used to switch the content indicated by the first information from not reporting second information to reporting second information. Optionally, the third information is carried in media access control element (MAC CE) or downlink control information (DCI).

[0058] For example, when a terminal device receives a CSI-ReportConfig file with the field `reportQuantity` equal to `none`, it indicates that the terminal device does not need to report CSI. Later, if the network device recognizes a change in the propagation environment based on uplink measurements or other information from the terminal device (e.g., beamforming results) and requires CSI reporting, the network device can dynamically switch the value of `reportQuantity` via signaling (i.e., third information). For example, it can instruct a switch from `reportQuantity = none` to `reportQuantity = cri-RI-PMI-CQI`. After receiving the third information indicating a switch from `none` to `cri-RI-PMI-CQI`, the terminal device needs to report CSI, i.e., report CRI, RI, PMI, and CQI. Considering the signaling response time, to ensure the network device obtains CSI data as quickly as possible, it can use MAC CE or DCI signaling to indicate the switch between not reporting and reporting CSI. Optionally, the third information may include 3-4 bits to indicate the content after the switch. For example, the third information indicates that reportQuantity=none is switched to reportQuantity=reporting parameter. The reporting parameter after the switch can be indicated by 3-4 bits. For example, the following 7 reporting contents can be indicated by 3-4 bits: reportQuantity=cri-RI-PMI-CQI, reportQuantity=cri-RI-i1, reportQuantity=cri-RI-i1-CQI, reportQuantity=cri-RI-CQI, reportQuantity=cri-RSRP, reportQuantity=ssb-Index-RSRP, reportQuantity=cri-RI-LI-PMI-CQI.

[0059] Typically, CSI reporting (denoted as CSI-Report) and beam reporting (denoted as beam-Report) are two coexisting but independently operating mechanisms, each used to report different information. For example, the parameters for beam reporting are unrelated to the information indicated in the reportQuantity field of CSI-ReportConfig (e.g., CQI, PMI, RI, etc.). Beam reporting includes the reporting of beam-related metrics, and network devices can be configured to allow terminal devices to feed back beam-related information for beam management on the network side. For example, the parameters in the beam measurement results may include one or more of the following: synchronization signal block / physical broadcast channel block (SS / PBCH block, SSB) index, channel state information reference signal (CSI-RS) index, RSRP (e.g., L1-RSRP of SSB, L1-RSRP of CSI-RS), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR), best beam index (e.g., SSB beam index or CSI-RS resource indication), beam ordering related information (e.g., candidate beam information, such as top-N beam list), CQI, PMI, RI, beam failure recovery information, etc.

[0060] As an example, the fields used for beam reporting may include the following:

[0061]

[0062] When the Boolean parameter (BOOLEAN) is set to true, it means that the reporting function of the corresponding parameter is enabled, that is, the parameter needs to be reported; when BOOLEAN is set to false, it means that the reporting function of the corresponding parameter is disabled, that is, the parameter does not need to be reported.

[0063] In some implementations, different reports can be associated. Optionally, if the second information includes CSI, the first information, in addition to instructing the terminal device whether to report the second information (i.e., CSI reporting), can also be used by the terminal device to determine whether to report beam measurement results. For example, it can be used by the terminal device to determine whether to report the results of the entire beam measurement, or to determine whether to report certain types of parameters (e.g., some parameters from SSB index, CSI-RS index, beam ID, RSRP, RSRQ, SINR, etc.).

[0064] For example, if the first information indicates that the terminal device should report CSI, the beam measurement results also need to be reported; or, if the first information indicates that the terminal device should not report CSI, the beam measurement results do not need to be reported. Taking the first information as the reportQuantity field in CSI-ReportConfig or a newly added field as an example, if reportQuantity = none or reportQuantity-R19 = none (i.e., indicating that CSI reporting is not required), the terminal device can ignore beam reporting, that is, it does not report the beam measurement results.

[0065] Optionally, the network device may send a fourth message to the terminal device. Correspondingly, the terminal device receives the fourth message sent by the network device. The fourth message is used to instruct the reporting function for specific parameters in the beam measurement results to switch from enabled to disabled, or from disabled to enabled; or, in other words, the fourth message is used to switch parameters that need to be reported in the beam measurement results from being ignored, or to switch parameters that do not need to be reported to be reported. Optionally, the fourth message is carried in MACCE or DCI.

[0066] Taking SSB index, CSI-RS resource index, and RSRP as examples: For SSB index, a parameter value of `true` indicates that the SSB index needs to be reported (or that the SSB index reporting function is enabled), and a parameter value of `false` indicates that the SSB index does not need to be reported (or that the SSB index reporting function is disabled). For CSI-RS resource index, a parameter value of `true` indicates that the CSI-RS resource index needs to be reported (or that the CSI-RS resource reporting function is enabled), and a parameter value of `false` indicates that the CSI-RS resource index does not need to be reported (or that the CSI-RS resource reporting function is disabled). For RSRP, a parameter value of `true` indicates that the RSRP needs to be reported (or that the RSRP reporting function is enabled), and a parameter value of `false` indicates that the RSRP does not need to be reported (or that the RSRP reporting function is disabled). If the fourth information received by the terminal device indicates that the parameter value corresponding to the SSB index changes from true to false, the parameter value corresponding to the CSI-RS resource index changes from false to true, and the parameter value corresponding to the RSRP changes from true to false, then when the first information indicates that the terminal device does not need to report CSI, the terminal device does not need to report the SSB index and RSRP when reporting beams, but it does need to report CSI-RS.
