[0105] The specific implementation of the present application is described below with reference to the drawings in the embodiments of the present application.

[0106] The embodiments of the present application can be applied to various communication systems, such as: global system for mobile communications (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WIMAX) communication system, 5G system or new radio (NR), or applied to future communication systems or other similar communication systems (such as 6G, etc.), or ultra wide band (UWB) system, or wireless fidelity (WiFi) system.

[0107] Figure 1 shows a possible, non-limiting system diagram. As shown in Figure 1 , the communication system 1000 includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The radio access network 100 may include at least one radio access network device (such as 110a and 110b in Figure 1 ) and at least one terminal (such as 120a-120j in Figure 1 ). The terminal is wirelessly connected to the radio access network device, and the radio access network device is wirelessly or wiredly connected to the core network. The core network device and the radio access network device may be independent, distinct physical devices, or the core network device's functions and the radio access network device's logical functions may be integrated into the same physical device, or a single physical device may integrate some of the core network device's functions and some of the radio access network device's functions. Terminals and radio access network devices may be interconnected via wired or wireless connections. Figure 1 is merely a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1 .

[0108] The radio access network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5G mobile communication system, a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The radio access network device can also be an open access network (open RAN, O-RAN or ORAN) or a cloud radio access network (CRAN). The radio access network device can also be a communication system that integrates two or more of the above systems. The radio access network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, etc.

[0109] In addition, the radio access network device may also be a module or unit that performs some of the functions of the base station, for example, a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any of the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0110] The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network equipment. For the convenience of description, the following description takes the base station as an example of the wireless access network equipment. It can be understood that the base station can be called a communication device. For example, the base station can be understood as a device with the function of a base station. For example, the device for implementing the function of the base station can be a base station; or some components in the base station, such as CU, DU, etc. It can also be a device that can support the base station to implement the function, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module. The device can be installed in the base station or can be used in conjunction with the base station. In the embodiment of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices.

[0111] Terminals can also be referred to as terminal devices, user equipment (UE), mobile stations, or mobile terminals. They can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, and smart home appliances.

[0112] The embodiments of this application do not limit the specific technology and specific device form used by the terminal. It is understood that the terminal can be referred to as a communication device. For example, the terminal can be understood as a device having terminal functions. For example, the device used to implement the terminal function can be a terminal; it can also be a device that supports the terminal to implement the function, such as a chip system, hardware circuit, software module, or hardware circuit and software module, which can be installed in the terminal or can be used in conjunction with the terminal.

[0113] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0114] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, drone 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.

[0115] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0116] Unless otherwise specified herein, the description is based on the “first device” and the “second device” as the execution entities, where the “first device” can be understood as a terminal, or a device having terminal functions, or a device that implements terminal functions. For example, the first device is a terminal, or the first device can be a module in the terminal (for example, a chip or circuit, etc.). Alternatively, the “first device” can be understood as a base station, or a device having base station functions, or a device that implements base station functions. For example, the first device is a base station, or the second device can be a module in a base station (for example, a chip or circuit, etc.), or a module or unit (for example, a CU, DU, or RU), a logic module, or software that fully or partially implements base station functions.

[0117] The "second device" can be understood as a terminal, or a device having terminal functions, or a device that implements terminal functions. For example, the second device is a terminal, or the second device can be a module in the terminal (for example, a chip or circuit, etc.). Alternatively, the "second device" can be understood as a base station, or a device having base station functions, or a device that implements base station functions. For example, the second device is a base station, or the second device can be a module in a base station (for example, a chip or circuit, etc.), or a module or unit (for example, CU, DU or RU), a logic module or software that fully or partially implements the base station functions.

[0118] In addition, "first device" can also be replaced by "first equipment" or "first communication device", and "second device" can also be replaced by "second equipment" or "second communication device".

[0119] In some possible implementation scenarios, the "first device" may be a "terminal" and the "second device" may be a "base station". Alternatively, the "first device" may be a "base station" and the "second device" may be a "terminal". For example, in Figure 2A, one or more terminals may communicate with the base station respectively. The interface between the terminal and the base station is a Uu interface.

[0120] In some possible implementation scenarios, the "first device" may be a "first terminal" and the "second device" may be a "second terminal". For example, in Figure 2B, terminal 1 can communicate with terminal 3, and terminal 2 can communicate with terminal 3. Among them, terminal 3 and terminal 1 can communicate through a side link, and similarly, terminal 3 and terminal 2 can communicate through a side link. In addition, if terminal 3 sends the data received from terminal 1 and the data received from terminal 2, terminal 3 can also send the data received from terminal 1, the data received from terminal 2, and its own data (that is, the data of terminal 3) to the base station. At this time, terminal 3 can also be understood as a relay terminal. The interface between terminal 3 and the base station is the Uu interface.

[0121] In some possible implementation scenarios, the "first device" may be a "first base station" and the "second device" may be a "second base station." For example, in Figure 2C , base station 1 and base station 2 may communicate. The interface between base station 1 and base station 2 may be an X2 interface.

[0122] In this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information is XX, and "sending information" can include direct sending, and also includes indirect sending through other units or modules. "Receiving information from YY" can be understood as the source of the information is YY, and "receiving information" can include receiving directly from YY, and also includes receiving indirectly from YY through other units or modules. In addition, "sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, "sending" or "receiving" can be performed between devices, for example, the base station and the terminal send or receive respectively through the air interface, and "sending" or "receiving" can also be performed within the device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, a line or an interface.

[0123] Wireless communication application scenarios are becoming increasingly diverse. Future wireless communication systems will generate a wealth of data tailored to these new scenarios, and new requirements will arise for transmitting this data. For example, new application scenarios such as ISAC, AI-enabled wireless technologies, and terahertz communications will generate massive amounts of data and signaling. Therefore, in future 6G radio access network systems, for example, multiple data types may exist, requiring transmission of different data types for different scenarios or tasks.

[0124] In the future wireless communication process, a large amount of native data will be generated. Native data can be understood as data derived from emerging application scenarios in future wireless communication systems (such as 6G), especially RAN data that needs to be transmitted over the air interface, or local data (local traffic) generated on the RAN side. Among them, native data can be simply referred to as data. Native data can include data of various data types (and possible data subtypes), such as perception data, artificial intelligence data, or channel data. Exemplarily, native data or native data types may include at least one of the following but are not limited to the following examples:

[0125] The first type is perception data, such as 2D or 3D imaging data (e.g., acquired environmental reflection points, environmental patches), environmental reconstruction data, point cloud data, radio frequency maps, or positioning data;

[0126] The second type is artificial intelligence data or edge artificial intelligence data, such as AI model data, training data, gradient data, gradient update data, inference results, feature information extracted by neural networks, performance data, etc.

[0127] The third type is channel data, such as the channel matrix, channel information fed back by devices in a multi-antenna system, and channel state information (CSI) data.

[0128] For example, in one implementation, the native data or native data type transmitted is perception data. In another implementation, the native data or native data type transmitted is point cloud data. In another implementation, the native data or native data type transmitted is positioning data and inference results.

[0129] For future wireless communication systems, in order to effectively and flexibly support secure and reliable data transmission in different scenarios and tasks, and to support the various data types and data subtypes that may exist in the native data of the next-generation mobile communication technology RAN, the present application provides a communication method, as shown in Figure 3, which includes:

[0130] Step 300: The first device determines first information.

[0131] The first information includes native data of M data types, where M is a positive integer, and the M data types are one or more of perception data, artificial intelligence data, and channel data. It is understood that this application only uses the data types of native data including perception data, artificial intelligence data, and channel data as examples for illustration. Furthermore, native data may also include other data types, which are not limited in this application.

[0132] Step 310: The first device sends first information to the second device. Correspondingly, the second device receives the first information from the first device.

[0133] The first information may be carried by first radio resource control (RRC) signaling.

[0134] Optionally, step 320: the second device parses the first RRC signaling, obtains the first information in the first RRC signaling, and performs corresponding operations according to the native data of the M data types included in the first information.

[0135] Exemplarily, step 320 is described below in conjunction with specific scenarios:

[0136] Scenario A: The first information includes artificial intelligence data and perception data.

[0137] For example, assuming that the first device is a terminal and the second device is a base station, the terminal can perform target tracking and positioning based on the artificial intelligence model to obtain artificial intelligence data (for example, inference results, which can be specifically location or border information, etc.), and the terminal can also obtain perception data (for example, reflection points or patches). The terminal can send first information to the base station, and the first information includes the terminal's perception data and the terminal's artificial intelligence data. The base station can then combine the terminal's perception data and the terminal's artificial intelligence data to improve the accuracy of target tracking and positioning.

[0138] Scenario B: The first information includes artificial intelligence data and channel data.

[0139] Exemplarily, assuming that the first device is a terminal and the second device is a base station, the terminal can predict subsequent channels based on an artificial intelligence model to obtain artificial intelligence data (for example, the inference result of the channel prediction), and the terminal can also obtain channel data through channel measurement. Compared with the terminal only feeding back channel data, the terminal can send first information to the base station, and the first information includes the terminal's channel data and the terminal's artificial intelligence data. Then, the base station can combine the terminal's channel data and the terminal's artificial intelligence data to determine more accurate multiple-input multiple-output (MIMO) transmission parameters (for example, precoding matrix).

[0140] Scenario C: The first information includes perception data and channel data.

[0141] Exemplarily, assuming that the first device is a terminal and the second device is a base station, the terminal can obtain channel data through channel measurement, and the terminal can also obtain perception data (such as reflection points or patches, etc.). Compared with the terminal only feeding back channel data, the terminal can send first information to the base station. The first information includes the terminal's channel data and the terminal's perception data. Then, the base station can combine the terminal's channel data and the terminal's perception data to determine more accurate MIMO transmission parameters.

[0142] The above scenarios A to C are for example purposes only and are not intended to limit this application. By reporting native data of multiple data types to the second device, at least one of the following technical effects can be achieved: improving the accuracy of artificial intelligence task execution, improving perception accuracy, and improving the accuracy of communication parameters (such as MIMO transmission parameters).

[0143] The above method shown in Figure 3 utilizes the bearer of RRC signaling to ensure better security and integrity of different types of native data, and can support the transmission of larger amounts of data in new scenarios of future wireless systems. In addition, it can have good scalability and maintainability, and is convenient for supporting the various data types and data subtypes that may exist in the native data of the next generation mobile communication technology RAN, thereby effectively and flexibly supporting the secure and reliable transmission of data in different scenarios and different tasks.

[0144] The following describes possible implementations of the first information:

[0145] In one possible implementation, the first information includes native data of M data types. For example, the first information includes perception data, or the first information includes perception data and artificial intelligence data.

[0146] In another possible implementation, the first information includes native data of M data types, the first data type is any one of the M data types, the native data of the M data types include native data of the first data type, the native data of the first data type includes native data of K data subtypes, and K is a positive integer.

[0147] It is understandable that the first data type may include multiple data subtypes, and the K data subtypes may be part or all of the multiple data subtypes included in the first data type. Exemplarily, the data subtypes of the perception data may include one or more of reflection point information, patch information, environmental map information, radio frequency map information, or electromagnetic signals. The data subtypes of the artificial intelligence data may include one or more of training data, model data, inference results, or performance data. The data subtypes of the channel data may include channel matrix data and / or channel state information data. For details, please refer to Table 1 below. In addition, the data subtypes of the perception data, the data subtypes of the artificial intelligence data, or the data subtypes of the channel data may also include other data subtypes, which are not limited in this application.

[0148] Table 1

[0149] Example 1: If the first data type is perception data, the native data of the first data type may include reflection point information and environment map information.

[0150] Example 2: If the first data type is artificial intelligence data, the native data of the first data type may include performance data.

[0151] Example 3: Assume that M=2, and the M data types include sensing data and channel data, wherein the sensing data may include reflection points, and the channel data includes channel state information data.

[0152] Example 4: Assume M = 2, and the M data types include perception data and artificial intelligence data. Perception data may include reflection point information and environment map information. Artificial intelligence data includes inference results and performance data.

[0153] The above examples 1 to 4 are merely examples and are not intended to limit the present application.

[0154] Furthermore, in a possible example, the first data subtype is any one of K data subtypes, and the first information also includes status information corresponding to the first data subtype, and the status information corresponding to the first data subtype includes compression information and / or a timestamp. The compression information can be used to indicate whether the native data of the first data subtype has been compressed. The timestamp can be used to indicate the collection time of the native data of the first data subtype. The timestamp can also be called time information, or collection time information. The second device can determine the timeliness of the native data of the first data subtype based on the timestamp. For example, the second device expects to obtain the native data of data subtype A from 17:00 to 19:00 on a certain day. The first device sends the first information, and the first information includes the native data of data subtype A and the status information of data subtype A, wherein the status information of data subtype A includes a timestamp, and the timestamp indicates that the collection time of the native data of data subtype A is 15:40. Then the second device can determine that the native data of data subtype A is expired or unavailable based on the timestamp.

[0155] Exemplarily, if the first data type is perception data, and the first data subtype is one of the data subtypes included in the perception data, such as reflection point information, patch information, etc., then the status information of the first data subtype may also include physical entity information. For details, please refer to the following relevant examples.

[0156] Exemplarily, if the first data type is artificial intelligence data, and the first data subtype is one of the data subtypes included in artificial intelligence data, such as training data, model data, etc., then the status information of the first data subtype may also be version information. For details, please refer to the following relevant examples.

[0157] The signaling format of the first information is introduced below:

[0158] For example, the first information may indicate M data types and also include native data of the M data types. Alternatively, information indicating a data type may be embedded in the first information, such that the first information not only indicates a data type but also includes data of the corresponding data type.

[0159] For example, the first information may be recorded as DataInfo, which may be a newly added information element (IE) in RRC signaling. DataInfo may adopt the RRC SEQUENCE format and use a nested multi-layer representation method, and implicitly indicate the data type or data subtype of the currently transmitted data by the presence or absence of the information. The specific signaling format example is as follows:

[0160] The above DataInfo signaling format is described as follows:

[0161] 1. DataInfo can contain three optional information: sensing-DataInfo, ai-DataInfo, and channel-DataInfo. Sensing-DataInfo corresponds to SensingDataInfo, ai-DataInfo corresponds to AIDataInfo, and channel-DataInfo corresponds to ChannelDataInfo. In other words, the three optional information correspond one-to-one to the three data type IEs. Therefore, DataInfo can indicate three data types: sensing data, artificial intelligence data, and channel data.

[0162] SensingDataInfo represents the IE corresponding to the sensing data and can contain five optional information, namely pointCloud-Data, polygon-Data, environmentMap-Data, radioFreqMap-Data, and signalMatrix-Data. Among them, pointCloud-Data corresponds to PointCloud, polygon-Data corresponds to Polygon, environmentMap-Data corresponds to EnvironmentMap, radioFreqMap-Data corresponds to RadioFreqMap, and signalMatrix-Data corresponds to SignalMatrix. That is, the five optional information correspond one-to-one to the five data subtype IEs. These five optional information are used to carry the native data of the corresponding data subtype, that is, SensingDataInfo can both indicate the data subtype and carry the corresponding native data. Among them, the five data subtypes are reflection point information, patch information, environment map information, radio frequency map information, and electromagnetic signal.

[0163] AIDataInfo represents the IE corresponding to artificial intelligence data and can contain four optional information: training-Data, model-Data, inference-Data, and performance-Data. Among them, training-Data corresponds to TrainingData, model-Data corresponds to ModelData, inference-Data corresponds to InferenceResult, and performance-Data corresponds to PerformanceResult. In other words, the four optional information correspond one-to-one with the four data subtype IEs. These four optional information are used to carry the native data of the corresponding data subtype, that is, AIDataInfo can both indicate the data subtype and carry the corresponding native data. Among them, the four data subtypes are training data, model data, inference results, and performance data.

[0164] ChannelDataInfo represents the IE corresponding to the channel data and can contain two optional information, h-Data and csi-Data. h-Data corresponds to HData, and csi-Data corresponds to CSIData. That is, the two optional information correspond one-to-one with the two data subtype IEs. These two optional information are used to carry the native data of the corresponding data subtype, that is, ChannelDataInfo can both indicate the data subtype and carry the corresponding native data. Among them, the two data subtypes are channel matrix data and channel state information data.

[0165] It can be understood that the number of optional information, the number of data type IEs, and the number of data subtype IEs in the above signaling format are only examples. DataInfo can be expanded to indicate more data types and data subtypes, and carry corresponding native data.

[0166] 2. Constraints on the DataInfo format: When sending DataInfo, it is necessary to ensure that at least one of the three optional information in DataInfo is selected (that is, native data of one or more data types is sent at a time). Furthermore, for the selected information in DataInfo, it is necessary to ensure that at least one of the one or more optional information included in the data type IE corresponding to the selected information is selected.

[0167] For example, if sensing-DataInfo is the selected information in DataInfo, then at least one of the five optional information in its corresponding data type IE (ie, SensingDataInfo) is selected.

[0168] In combination with Example 4 above, assume that M = 2, and the M data types include perception data and artificial intelligence data. Among them, perception data can include reflection point information and environmental map information. Artificial intelligence data includes inference results and performance data. Then DataInfo can be expressed as:

[0169] In the above DataInfo, sensing-DataInfo and ai-DataInfo are selected, indicating that the data type of this transmission includes perception data and artificial intelligence data, or the data type of this transmission includes perception data and artificial intelligence data. In the data type IE (SensingDataInfo) corresponding to sensing-DataInfo, pointCloud-Data and environmentMap-Data are selected, indicating that perception data includes reflection point information and environment map information. Among them, pointCloud-Data is used to carry specific reflection point information, PointCloud is used to indicate that the data subtype is reflection point information, and environmentMap-Data is used to carry specific environment map information, and EnvironmentMap is used to indicate that the data subtype is environment map information. In the data type IE (AIDataInfo) corresponding to ai-DataInfo, inference-Data and performance-Data are selected, indicating that artificial intelligence data includes inference results and performance data. Among them, inference-Data is used to carry specific inference results, InferenceResult is used to indicate that the data subtype is inference result, and performance-Data is used to carry specific performance data, and PerformanceResult is used to indicate that the data subtype is performance data.

[0170] Furthermore, in one possible design, the first device may also send second information to the second device, where the second information indicates M data types. That is, the second information may indicate the data type of the native data to be transmitted. Furthermore, the second information may also indicate the data subtype included in each of the M data types. That is, the second information may indicate the data subtype of the native data to be transmitted.

[0171] The second information is carried by the first RRC signaling; or the second information is carried by the second RRC signaling. Exemplarily, the first RRC signaling includes the first information and the second information. Alternatively, the first RRC signaling includes the first information, and the second RRC signaling includes the second information, wherein the first RRC signaling is different from the second RRC signaling.

[0172] For example, the second information may be sent before the first information, that is, the second RRC signaling is sent first and the first RRC signaling is sent later. As a possible implementation, the second information may be sent periodically, or the second information may be sent semi-statically.

[0173] For example, the first device may periodically send the second information, and thereby periodically notify the second device of which data types of native data are included in the first information.

[0174] For another example, the first device determines that the data type of the native data included in the first information is adjusted from X1 data types to X2 data types, where the X1 data type is different from the X2 data types, and X1 and X2 are positive integers. Before the data type of the native data included in the first information is adjusted to X2 data types, the first device can send the second information. At this time, the second information indicates that the first information includes native data of X2 data types. When the data type of the native data included in the first information has not changed, the first device may not need to send the second information. Therefore, it is possible to promptly notify the second device of which data types of native data are included in the first information, and it is also possible to save signaling overhead.

[0175] Exemplarily, the second information may be recorded as DataType, which is another newly added IE in RRC signaling. DataType is used to configure the data type of the native data to be sent, or the data type and data subtype of the native data to be sent. DataType may adopt the RRC SEQUENCE format and use a nested multi-layer representation method, and indicate the data type, or the data type and data subtype, by the presence or absence of information. The specific signaling format example is as follows:

[0176] The specific signaling format of the above DataType is described as follows:

[0177] 1. DataType can contain three optional information, namely sensingDataSubType, aiDataSubType, and channelDataSubType. Among them, sensingDataSubType corresponds to SensingDataSubType, aiDataSubType corresponds to AIDataSubType, and channelDataSubType corresponds to ChannelDataSubType. That is, the three optional information correspond one-to-one to the three data subtype IEs. The three data types are sensing data, artificial intelligence data, and channel data. Optionally, DataType can also indicate more data types.

[0178] SensingDataSubType represents the IE corresponding to the data subtype of sensing data. It can contain five optional information: includePointCloud, includePolygon, includeEnvironmentMap, includeRadioFreqMap, and includeSignalMatrix. These five data subtypes represent reflection point information, patch information, environment map information, radio frequency map information, and electromagnetic signal information, respectively. Optionally, the data subtype of sensing data can be expanded to include more data subtypes.

[0179] AIDataSubType represents the IE corresponding to the data subtype of artificial intelligence data, which can contain four optional information, namely includeTrainingData, includeModelData, includeInferenceResult, and includePerformanceResult. These four data subtypes are training data, model data, inference results, and performance data, respectively. Optionally, the data subtype of artificial intelligence data can also be expanded to more data subtypes.

[0180] ChannelDataSubType represents the IE corresponding to the data subtype of the channel data, which can contain two optional information, namely includeHData and includeCSIData. These two data subtypes are channel matrix data and channel state information data, respectively. Optionally, the data subtype of the channel data can also be extended to more data subtypes.

[0181] The above-mentioned SensingDataSubType, AIDataSubType and ChannelDataSubType can all indicate whether the data subtype is included by enumerating the ENUMERATED variable. When the ENUMERATED variable indicates true, it means that the native data of the corresponding data subtype needs to be sent. When the native data of a certain data subtype does not need to be sent, the information corresponding to the data subtype may not be included.

[0182] 2. Constraints on the DataType format: When sending DataType, it is necessary to ensure that at least one of the three optional information in DataType is selected (that is, DataType can indicate one or more data types). Furthermore, for the selected information in DataType, it is necessary to ensure that at least one of the one or more optional information included in the data subtype IE corresponding to the selected information is selected, that is, the ENUMERATED variable corresponding to the selected information indicates true.

[0183] For example, if sensingDataSubType is the selected information in DataType, then at least one of the five optional information in the data subtype IE (ie, SensingDataSubType) corresponding to sensingDataSubType is selected.

[0184] In conjunction with Example 3 above, assuming M = 2, the M data types include sensing data and channel data, where sensing data may include reflection point information. Channel data includes channel state information data. The corresponding DataType in the above example can be expressed as:

[0185] The corresponding DataInfo in the above example can be expressed in signaling format A or signaling format B:

[0186] Among them, the signaling format A is as follows:

[0187] Signaling format B is as follows:

[0188] It can be seen from the above signaling format A and signaling format B that when sending the second information, the first information can adopt the simplified signaling format B, thereby saving signaling overhead.

[0189] For example, in one possible implementation, the second information indicates X data subtypes, each of which belongs to M data types, where each data type includes at least one data subtype, and X and M are positive integers. That is, the second information indicates the M data types and the data subtypes included in each of the M data types, where the total number of data subtypes involved in the M data types is X. In this case, the first information may include the native data corresponding to each of the X data subtypes, without further indicating the M data types. For example, if the signaling format of the second information remains unchanged and is mandatory, the first information may use the aforementioned signaling format B.

[0190] As can be seen from the above, as a possible implementation method, the first device can send the first information, but not the second information, and the first information is carried by the first RRC signaling. For the convenience of description, this possible implementation method is hereinafter referred to as Method 1. Among them, Method 1 can also be understood as a method of implicitly indicating the data type (and data subtype),

[0191] As another possible implementation, the first device may send the first information and the second information, wherein the first information and the second information may be carried by the same RRC signaling or by different RRC signaling. For the convenience of description, this possible implementation is hereinafter referred to as Method 2. Method 2 can be understood as a method for displaying the indicated data type (and data subtype). The following description will only be based on the example of the first information and the second information being carried by the same RRC signaling (i.e., the first RRC signaling).

[0192] Furthermore, the following describes possible implementations of the first RRC signaling for different application scenarios:

[0193] Possible Implementation A: The first RRC signaling is a system information block (SIB) or an RRC reconfiguration message. The SIB is a broadcast signaling.

[0199] Possible Implementation Method C: The first RRC signaling is a measurement report sidelink message, an RRC reconfiguration sidelink message, or an RRC reconfiguration complete sidelink message. Possible Implementation Method C is applied to a sidelink scenario. In addition, the first RRC signaling may also be other RRC signaling applied to a sidelink scenario, which is not limited in this application.

[0207] Furthermore, when the first information carries perception data, the first information may include but is not limited to one or more of the following fields.

[0208] 1. Reflection point (point cloud) field

[0209] The reflection point field includes a data point (scatterPoint) field. Exemplarily, the data point field includes the number of data points (pointNumber) n and the parameters corresponding to the n data points, wherein the parameters here may include one or more of coordinates, power, delay, and angle, and n is a positive integer.

In addition, n is less than or equal to the maximum number of data points (maxPointNumber), wherein the maximum number of data points is also the maximum number of data points that can be carried or recorded.

[0210] Optionally, the reflection point field may also include one or more of the following status information: a timestamp, compression information, and physical entity information. The timestamp may indicate the acquisition time of the content carried by the data point field, and the compression information may indicate whether the content carried by the data point field is compressed. The physical entity information may indicate the physical entities corresponding to the n data points. For example, the physical entity information may include at least one physical entity index, where each physical entity index corresponds to a physical entity, such as a wall or a building. The correspondence between the physical entity index and the physical entity may be configured in advance.

[0211] For example, n data points can be represented by [P0, P1, P2, ..., P n-1 ] indicates that the data point field indicates the number of data points n and P0, P1, P2, ..., P n-1 The corresponding parameters respectively. Among them, P i is any one of the n data points, and i is an integer greater than or equal to 0 and less than n-1. i The corresponding coordinates can be the coordinates in the rectangular coordinate system, for example (X i ,Y i ,Z i ), or P i The corresponding coordinates can also be coordinates in the polar coordinate system, for example, Among them, ρ i Called P i The corresponding polar diameter, θ i and Called P i The corresponding polar angle and azimuth angle.

[0212] It can be understood that the first information includes a reflection field, which can be understood as the first information including data of a reflection point subtype, that is, the first information includes the data of the reflection point.

The timestamp may indicate the acquisition time of the content carried by the patch information field, and the compression information may indicate whether the content carried by the patch field is compressed.

The specific implementation method can refer to the above-mentioned related content.

[0219] It can be understood that the first information includes the facet field, which can be understood as the first information including data of the facet subtype, that is, the first information includes facet data.

[0220] For example, the patch field can be represented by Polygon. The specific example of Polygon is as follows:

[0221] 3. Environment Map Field

[0222] The Environment Map field includes the number of environment elements (m), the information corresponding to each of the m environment elements, and the type of the environment element. The type of the environment element can be any of map base elements, map grid data, or map vector data, and m is a positive integer. The type of the environment element can also be understood as a data subtype of the environment element.

[0223] It can be understood that the specific content included in the information corresponding to the m environmental elements is determined based on the type of the environmental element.

[0224] For example, if the type of the environment element is a map base element, m environment elements are also m map base elements, which can be referred to as m base elements. The m base elements can be represented by [E0, E1, E2, ..., E m-1 ] indicates that m is a positive integer. In addition, m is less than or equal to the maximum number of base elements (maxBaseElementNumber), where the maximum number of base elements is the maximum number of base elements that can be carried or recorded. E i is any one of the m basic elements, E i The information (ie, the information corresponding to each environmental element) can represent the geometric information of the environment, and may include elements such as points, surfaces, and bodies.

[0225] For example, if the type of environmental element is map grid data, the information corresponding to each of the m environmental elements is also m map grid data. Map grid data can also be called spatial grid data, or simply grid data. For example, each grid data (i.e., the information corresponding to each environmental element) includes a number of pixels, stored as a two-dimensional array. The values ​​of the two-dimensional array are attribute values. For example, the attribute values ​​can include one or more of the three primary colors (red, green, and blue, RGB), temperature, humidity, altitude, and reflectivity.

A geographic feature object is a combination of multiple different geometric objects. The information corresponding to the geographic feature object (that is, the information corresponding to each environmental element) includes information corresponding to multiple different geometric objects. Among them, geographic vector data includes spatial data and attribute data, wherein spatial data is used to represent geometric objects and / or geographic feature objects, and attribute data includes non-geometric characteristics used to describe geometric objects and / or geographic feature objects, such as name, temperature, humidity, reflectivity, etc.

From a functional point of view, if the matrix data includes a channel signal, it can enable the artificial intelligence model to learn the characteristics of the channel, thereby assisting communication tasks (such as beamforming, beam tracking, etc.) or perception tasks (such as object recognition, target tracking, etc.), and achieving higher transmission rates or perception accuracy. If the matrix data includes an image signal, it can enable the artificial intelligence model to learn the characteristics of the communication environment, thereby assisting communication tasks or perception tasks, and achieving higher transmission rates or perception accuracy.
