[0056] The technical solution provided in this application will now be described with reference to the accompanying drawings.

[0057] The embodiments of this application can be applied to various communication systems, such as wireless local area network (WLAN) systems, narrow band internet of things (NB-IoT) systems, global system for mobile communications (GSM) systems, enhanced data rate for GSM evolution (EDGE) systems, wideband code division multiple access (WCDMA) systems, code division multiple access 2000 (CDMA2000) systems, time division-synchronization code division multiple access (TD-SCDMA) systems, long term evolution (LTE) systems, satellite communication systems, sidelink (SL) systems, 5th generation (5G) systems, or future communication network systems, etc.

[0058] Figure 1This is a schematic diagram of the architecture of a communication system applicable to embodiments of this application. The communication system includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (e.g., Figure 1 110a and 110b (collectively referred to as 110) and at least one terminal device (such as Figure 1 120a-120j, collectively referred to as 120, are included in the RAN. The RAN may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices. Figure 1 (Not shown in the image). Terminal device 120 is connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 wirelessly or via wired connection. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0059] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, non-terrestrial network (NTN) systems, or future communication network systems. RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system, or a communication system that integrates two or more of the above systems.

[0060] The terminal device 120 involved in this application embodiment can also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc.

[0061] The RAN node 110 involved in this embodiment can also be called an access network device, RAN entity, or access node, etc., and constitutes part of the communication system to help terminal devices achieve wireless access. Multiple RAN nodes 110 in the communication system 1000 can be nodes of the same type or different types. In some scenarios, the roles of the RAN node 110 and the terminal device 120 are relative, for example, Figure 1 Network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminal devices 120j that access RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal devices 120 are sometimes referred to as communication devices, for example... Figure 1 Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a-120j can be understood as communication devices with terminal functions.

[0062] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), or a base station in a future communication network system. A RAN node can also be a macro base station (such as...). Figure 1 110a), micro base stations or indoor stations (such as Figure 1In CRAN scenarios, RAN nodes can be 110b, relay nodes, donor nodes, or wireless controllers. Optionally, RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in vehicle-to-everything (V2X) technology, the access network equipment can be a roadside unit (RSU).

[0063] In another possible scenario, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, with different RAN nodes implementing some of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as the baseband unit (BBU). The CU and DU nodes separate the gNB's protocol layers; some protocol layer functions are centrally controlled by the CU, while the remaining partial or complete protocol layer functions are distributed in the DU, which is centrally controlled by the CU. As one implementation, the CU deploys the RRC layer, Packet Data Convergence Protocol (PDCP) layer, and Service Data Adaptation Protocol (SDAP) layer in the protocol stack; the DU deploys the radio link control (RLC) layer, media access control (MAC) layer, and physical layer (PHY) in the protocol stack. Thus, the CU has the processing capabilities for RRC, PDCP, and SDAP. The DU has the processing capabilities for RLC, MAC, and PHY. It is understood that the above functional division is merely an example and does not constitute a limitation on the CU and DU. The RU can be included in radio frequency equipment or radio frequency units, such as in a remote radio unit (RRU), active antenna unit (AAU), or remote radio head (RRH).

[0064] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open radio access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through a software module, a hardware module, or a combination of software and hardware modules.

[0065] The core network equipment involved in the embodiments of this application refers to the equipment in the core network (CN) that provides service support for terminal equipment. Currently, some examples of core network equipment include: access and mobility management function (AMF) entities, session management function (SMF) entities, user plane function (UPF) entities, etc., which will not be listed here. Among them, the AMF entity can be responsible for the access management and mobility management of terminal equipment; the SMF entity can be responsible for session management, such as user session establishment; the UPF entity can be a user plane functional entity, mainly responsible for connecting to external networks. It should be noted that in this application, entities can also be called network elements or functional entities. For example, an AMF entity can also be called an AMF network element or an AMF functional entity, and an SMF entity can also be called an SMF network element or an SMF functional entity, etc.

[0066] Figure 2 This is an example diagram of an O-RAN system, which may include... Figure 2 Other components besides those shown. For example... Figure 2 As shown, access network devices (such as eNB, gNB, or next-generation access network devices) communicate with the core network (CN) via backhaul links and with terminal devices via air interfaces.

[0067] Specifically, the baseband unit (BBU) in the access network equipment communicates with the core network via a backhaul link, and the radio unit (RU) in the access network equipment communicates with at least one terminal device via an air interface. The BBU communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0068] The BBU includes at least one CU and at least one DU, which can communicate via at least one midhaul link.

[0069] There is an interface between the DU and RU. Depending on the functions of the DU and RU, and / or the different switching methods, the interface between the DU and RU can be a common public radio interface (CPRI) or an enhanced common public radio interface (eCPRI).

[0070] To facilitate understanding of the embodiments of this application, the technical solutions related to the embodiments of this application will be briefly introduced below.

[0071] In 5G NR, channel state information is obtained through CSI-RS measurement. The configuration of CSI-RS mainly includes CSI-RS resource configuration and CSI report configuration. The CSI-RS transmission process consists of two parts: the CSI-RS transmission process and the channel state information (CSI) reporting process. Figure 3 This is a schematic diagram of the CSI-RS transmission process. The base station can send CSI-RS resource configuration and CSI report configuration to the terminal device via radio resource control (RRC) signaling. The base station periodically sends CSI-RS to the terminal device, and the terminal device periodically receives CSI-RS from the base station according to the CSI-RS resource configuration. The terminal device obtains the CSI report based on the received CSI-RS and periodically sends the CSI report to the base station according to the CSI report configuration. The CSI report may be carried on PUCCH.

[0072] Wireless sensing technology, as one of the electromagnetic wave sensing technologies, can be used as an important alternative technology for security inspection, hidden object detection, environmental reconstruction and monitoring due to its penetration and security.

[0073] Enabling 6G intelligent technologies requires acquiring sensory information from the environment. To conserve spectrum, hardware resources, and computing power, the integration of communication and sensing is becoming a trend. Using environmental information obtained through sensing to assist communication in achieving higher spectrum efficiency or obtaining a more robust, resilient, and easily recoverable network has become an important topic in sensing-assisted communication.

[0074] Radio frequency (RF) channel maps can be generated using methods such as sensing and prediction. Currently, many schemes have been designed for the use of RF channel map data, but there is no systematic design for the transmission and control of RF channel map data within the physical layer. The problem of how to acquire RF channel map data urgently needs to be solved. This application will refer to the CSI report configuration in 5G NR to achieve the acquisition of RF channel map data.

[0075] I. Grid data of radio frequency channel map

[0076] The generation of radio frequency (RF) channel maps begins with describing the physical world through environmental reconstruction. Then, the scene is divided into grids. After the gridding is complete, the RF channel map is solved using the reconstructed environment or the real physical world. Multipath component (MPC) is a type of RF channel map data. Multipath components include, but are not limited to, signal received power, signal transmission delay, signal angle of arrival (AoA), and signal angle of departure (AoD). Figure 4a , Figure 4b , Figure 4c and Figure 4d This is a schematic diagram illustrating the process of generating a radio frequency channel map; specifically, it first generates a map like this... Figure 4a The physical world map shown (bird's-eye view); regenerated as... Figure 4b The perceptual reconstruction map shown is an aerial view; the map is then divided into grids, as follows: Figure 4c As shown; the final output is as follows Figure 4d The radio frequency channel map shown.

[0077] Table 1 shows the grid data of the radio frequency channel map generated by sensing. It should be noted that the physical meaning of sensing quality is the difference between the channel information in the radio frequency channel map generated by sensing and the channel information obtained through measurement.

[0078] Table 1

[0079]

[0080] Among them, Power kDelay represents the received power of the signal corresponding to the k-th path in the i-th grid. k AoA represents the transmission delay of the signal corresponding to the k-th path in the i-th grid. k Angle of arrival (AoD) represents the angle of arrival of the signal corresponding to the k-th path in the i-th grid. k Let K represent the departure angle of the signal corresponding to the k-th path in the i-th grid, where K represents the number of paths in the i-th grid and n represents the number of scatterers in the i-th grid.

[0081] The perceived quality corresponding to the i-th grid can be represented by the following formula (1):

[0082]

[0083] in, This represents the received power of the actual measured signal corresponding to the k-th path in the i-th grid. This represents the angle of arrival of the actual measured signal corresponding to the k-th path in the i-th grid. This represents the departure angle of the actual measured signal corresponding to the k-th path in the i-th grid.

[0084] II. Regional Data of Radio Frequency Channel Map

[0085] In entities with sensing or sensing fusion capabilities, such as TRPs / base stations / terminal equipment, or entities with sensing capabilities such as SMFs / location management functions (LMFs), there is regional data for radio frequency channel maps. Table 2 shows the regional data for radio frequency channel maps generated through sensing.

[0089] Region boundary information is used to characterize the region extent, and the region boundary information includes the grid ID used to characterize the region extent. Figure 5 This is a schematic diagram of the area edge information of the radio frequency channel map; the grid IDs used to represent the range of this area are {4,5,11,14,18,23,26,32,35,39,43,46,51,53,60}.

[0090] The regional data for the radio frequency channel map includes the following:

[0091] 1) Area ID: The ID of the radio frequency channel map partition;

[0092] 2) Regional boundary information;

[0093] 3) Extended expressions: Extended expressions based on region-specific channel information, including but not limited to extended expressions for multipath components, power delay profile (PDP), and channel impulse response (CIR);

[0096] 6) Perceived quality: The perceived quality of a region can be understood as the accuracy of perception and the quality of service.

[0097] This application provides a communication method that enables the acquisition of radio frequency channel map data, thereby improving the ability to perform sensing-assisted communication and positioning.

Furthermore, the processing performed by a single execution entity can be divided into multiple execution entities, which can be logically and / or physically separated. For example, the processing performed by the network device can be divided into at least one execution entity among CU, DU, RU, etc.

[0099] S610, the first communication device sends first information to the second communication device, the first information being used to request second information, the second information including information from a generative model and / or radio frequency channel map data, the generative model being used to generate the radio frequency channel map data. Correspondingly, the second communication device receives the first information from the first communication device.

[0100] For example, the first information is used to request information about the generative model, and the first communication device can generate radio frequency channel map data based on the information about the generative model. For example, the first information is used to request information about the radio frequency channel map data. For example, the first information is used to request information about the generative model and radio frequency channel map data, and when the first communication device moves from the current area to another area, the generative model can be used to generate radio frequency channel map data for that other area.

[0101] Optionally, the data type of the radio frequency channel map data includes at least one of the following: multipath components, channel state information, or a channel matrix. The channel matrix can be represented as H. It should be noted that the multipath components, channel state information, and channel matrix are generated by the second communication device through sensing. These components can be interconverted; for example, the channel matrix can be generated from multipath components, and multipath components can be extracted from the channel matrix.

[0102] For example, the radio frequency channel map data corresponding to the multipath components includes at least one of the following: the transmission delay of the signal corresponding to each path, the angle of arrival of the signal, the angle of departure of the signal, the arrival power of the signal, the phase of the signal, the bounce order of the path, or the identification of the scatterer.

[0103] For example, the radio frequency channel map data corresponding to the channel state information includes at least one of the following: channel state information reference signal resource indicator (CSI-RS resource indicator, CRI), rank indicator (RI), precoding matrix indicator (PMI), channel quality indicator (CQI), or layer indicator (LI).

[0104] For example, the information in a generative model includes information about a dedicated generative model and information about a general generative model. A dedicated generative model is used only to generate a certain type of data in the radio frequency channel map data, such as generating signal transmission delay. A general generative model can be used to generate one or more types of data or even all data in the radio frequency channel map data. For example, it can be used not only to generate signal transmission delay but also to generate radio frequency channel map data such as signal departure angle, signal arrival angle, and signal arrival power. Furthermore, a dedicated generative model may only be applicable to certain specific areas, while a general generative model may be applicable to all areas within the same scene or areas in different scenes.

[0105] For example, general generative models include, but are not limited to: autoregressive model (AR) model, generative adversarial network (GAN) model, normalizing flow model, variational auto-encoder (VAE) model, or denoising diffusion probabilistic model (DDPM).

[0106] Figure 7This diagram illustrates the generation of radio frequency channel map data by processing input information using a generative model. The input information for a general generative model can be sensing information or environmental reconstruction results for the current area, a small amount of measurement data for the current area, or both sensing information and a small amount of measurement data for the current area.

[0107] For example, different data types of radio frequency channel map data correspond to different indices. Table 3 shows examples of indices corresponding to different data types of radio frequency channel map data. Here, "0" represents multipath components, "1" represents channel state information, "2" represents the channel matrix, "3" represents generative model information, and "4" represents other data types of radio frequency channel map data. It should be noted that although the generative model information is not generated through sensing, the generative model is used to generate radio frequency channel map data; therefore, the generative model information can be considered a special data type of radio frequency channel map data.

[0108] Table 3

[0109] index Data types of radio frequency channel map data 0 Multipath components 1 Channel state information 2 Channel matrix 3 Information from generative models 4 Other data types of radio frequency channel map data

[0110] For example, different radio frequency channel map data correspond to different indices. Table 3 shows examples of the indices corresponding to different radio frequency channel map data.

[0111] Table 4

[0112] index Radio frequency channel map data 0 signal transmission delay 1 Angle of arrival of the signal 2 Signal departure angle 3 signal arrival power 4 Phase of the signal 5 Number of bounces of the path 6 Identification of scatterers 7 Channel State Information Reference Signal Resource Indicator 8 Rank Indicator 9 Channel quality indication 10 Precoding matrix indication 11 Layer Indicator 12 Channel matrix 13 Information on dedicated generative models 14 Information on general generative models

[0113] For example, the first information includes an index of the generative model and an index of the radio frequency channel map data. For example, the first information includes an index of the generative model, an index of the data type, and an index of the radio frequency channel map data corresponding to the data type.

[0114] Optionally, the first information indicates at least one of the following: the format of the radio frequency channel map data, the report channel of the second information, the transmission method of the second information, or the resources used to transmit the second information. The transmission method of the second information can be understood as the report configuration type of the second information.

[0115] For example, the first information also includes an index of the format of the radio frequency channel map data, an index of the reporting channel, an index of the transmission method, and an index of the resources used to transmit the second information. The fields in the first information that indicate the format of the radio frequency channel map data, the reporting channel of the second information, the transmission method of the second information, and the resources used to transmit the second information are different.

[0116] For example, the format of radio frequency channel map data includes grid format and region format. Grid format radio frequency channel map data can be understood as the original grid-based radio frequency channel map data generated through sensing; region format radio frequency channel map data can be understood as data that has been partitioned into regions and processed or compressed based on region fitting.

[0117] Table 5 shows examples of different radio frequency channel map data formats and their corresponding indexes. "0" indicates grid format, and "1" indicates area format.

[0118] Table 5

[0119] index Format of radio frequency channel map data 0 Grid 1 area

[0120] Optionally, the reporting channels include PDSCH, PDCCH, PUSCH, PUCCH, PSSCH, PSCCH, PSFCH, or the Xn interface.

[0121] For example, the first communication device is a terminal device, the second communication device is a base station, and the reporting channel for the second information can be PDSCH or PDCCH. In this example, the terminal device requests the base station to send the second information.

[0122] For example, the first communication device is a base station, the second communication device is a terminal device, and the reporting channel for the second information can be PUSCH or PUCCH. In this example, the base station requests the terminal device to send the second information.

[0123] For example, the first communication device is a first terminal device, the second communication device is a second terminal device, and the reporting channel for the second information can be PSSCH, PSCCH, or PSFCH. In this example, the first terminal device in the sidelink communication scenario requests the second terminal device to send the second information.

[0124] For example, the first communication device is a first base station, the second communication device is a second base station, and the reporting channel for the second information can be an Xn interface.

[0125] Table 6 shows examples of different reporting channels used for transmitting radio frequency channel map data and their corresponding indexes.

[0126] Table 6

[0127] index Reporting Channel 0 PDSCH 1 PDCCH 2 PUSCH 3 PUCCH 4 PSSCH 5 PSCCH 6 PSFCH 7 Xn interface

[0128] Optionally, different reporting channels are required to transmit different second information (or radio frequency channel map data), and the reporting channels corresponding to different second information (or radio frequency channel map data) are predefined; the second communication device can know which reporting channel to use to send the second information to the first communication device based on the second information (or radio frequency channel map data) requested by the first communication device; in this optional implementation, the first information does not need to indicate the reporting channel of the second information.

[0129] Optionally, the transmission method of the second information includes a periodic transmission method, a semi-static transmission method, or an aperiodic transmission method. This can be understood as the reporting configuration type of the second information including periodic, semi-static, or aperiodic. For example, the first information indicates that the transmission method of the second information is a periodic transmission method, and the second communication device periodically sends the second information to the first communication device.

[0130] Table 7 shows examples of different sending methods (report configuration types) and their corresponding indexes. "0" represents a periodic sending method, "1" represents a semi-static sending method, and "2" represents a non-periodic sending method.

[0132] index Report configuration type (sending method) 0 Periodic 1 semi-static 2 non-periodic

[0133] Table 8 shows an example of the binding relationship between the format of radio frequency channel map data, the data type of radio frequency channel map data, the reporting channel, and the transmission method (report configuration type).

[0134] Table 8

[0135]

[0136] Optionally, the second information may also include at least one of RQI, antenna configuration information, or input information of the generative model, wherein the input information of the generative model includes sensing information and / or measurement information. For example, the first communication device may generate a channel matrix based on multipath component (MPC) and antenna configuration information; for another example, a radio frequency channel map quality indicator may indicate the quality of the current radio frequency channel map data to facilitate quality management of the radio frequency channel map data; for yet another example, the input information based on the generative model may include sensing information and actual (measured) channel information at certain locations. Based on the sensing information, a radio frequency channel map in the scenario of the sensing information can be generated using the generative model, and the actual (measured) channel information at certain locations can be used to fine-tune the parameters of the generative model to improve the accuracy of the generated radio frequency channel map data in the scenario.

[0137] For example, the antenna configuration information includes the number of antenna rows (num_rows), the number of antenna columns (num_cols), the antenna polarization mode, and the antenna pattern; wherein, the antenna polarization mode includes single polarization mode or dual polarization mode, and the antenna pattern includes omnidirectional mode or directional mode.

[0138] Optionally, the first information further indicates an RQI table, which indicates the selection of an RQI table, and the optional number of tables is T, where T≥1. Optionally, the first information further indicates whether the RQI to be acquired is the RQI corresponding to a single subband or the RQI corresponding to multiple subbands.

[0139] S620, the second communication device sends second information to the first communication device; specifically, the second communication device sends second information to the first communication device based on the first information. Correspondingly, the second communication device receives the second information from the first communication device.
