Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a method and apparatus for evaluating radio frequency data. Background Art

[0002] Currently, using the environmental information obtained by sensing to obtain higher spectral efficiency in sensing-assisted communication, or to obtain a more robust, elastic, and easily recoverable network has become the main topic of sensing-assisted communication. Sensing-assisted channel prediction, sensing-assisted positioning, etc. are important topics in sensing-assisted communication, and the environmental information obtained by sensing is used to predict radio frequency channel conditions such as communication and positioning.

[0003] However, there may be certain errors in the environmental information obtained by sensing. Such errors may be caused by the difference between the environmental information obtained by sensing and the real environmental information or electromagnetic environment, or may be losses caused by compressing the environmental information obtained by sensing for transmission and then expanding it to reduce communication pressure. Therefore, the accuracy of the environmental information obtained by sensing will affect the results of services such as sensing-assisted channel prediction and sensing-assisted positioning. Summary of the Invention

[0004] This application provides a method and apparatus for evaluating radio frequency data, in order to improve the performance of sensing-assisted communication.

[0005] In a first aspect, a method for evaluating radio frequency data is provided. This method can be executed by a first communication device, or by a chip / chip system. Among them, the first communication device can be a terminal device or a network device. Taking the execution by the first communication device as an example for illustration. In this method, the first communication device receives a quality measurement request. Based on the quality measurement request, the first communication device sends one or more of scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality. Among them, the scatterer quality characterizes the accuracy of the positions of the scatterers included in the first radio frequency channel mapping data, the radio frequency channel quality characterizes the deviation between the channel state measurement value and the channel state prediction value included in the first radio frequency channel mapping data, and the radio frequency channel mapping data application quality characterizes the usage quality of using the first radio frequency channel mapping data.

[0006] Based on the above solution, the first communication device can obtain radio frequency channel mapping data by using the environmental information obtained by sensing, and determine one or more of scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality based on the quality measurement request, so as to evaluate the accuracy of the radio frequency channel mapping data, and can evaluate whether the radio frequency channel mapping data can be applied to sensing-assisted communication such as sensing-assisted channel prediction and sensing-assisted positioning, so as to improve the performance of sensing-assisted communication.

[0007] In a possible implementation, the first communication device transmits multiple items among the scatterer mass, the radio frequency channel quality, and the radio frequency channel mapping data application quality. One or two of the multiple items among the scatterer mass, the radio frequency channel quality, and the radio frequency channel mapping data application quality satisfy the first transmission condition. For example, when the multiple items include the scatterer mass and the radio frequency channel quality, one or two of the multiple items satisfying the first transmission condition can be that one of the multiple items satisfies the first transmission condition, such as the scatterer mass meeting the first requirement. For another example, when the multiple items include the scatterer mass and the radio frequency channel mapping data application quality, one or two of the multiple items satisfying the first transmission condition can be that one of the multiple items satisfies the first transmission condition, such as the scatterer mass meeting the first requirement. For yet another example, when the multiple items include the radio frequency channel quality and the radio frequency channel mapping data application quality, one or two of the multiple items satisfying the first transmission condition can be that one of the multiple items satisfies the first transmission condition, such as the radio frequency channel quality meeting the second requirement. For yet another example, when the multiple items include the scatterer mass, the radio frequency channel quality, and the radio frequency channel mapping data application quality, one or two of the multiple items satisfying the first transmission condition can be that two of the multiple items satisfy the first transmission condition, such as the scatterer mass meeting the first requirement and the radio frequency channel quality meeting the second requirement.

[0008] Based on the above solution, the first communication device can transmit multiple items among the scatterer mass, the radio frequency channel quality, and the radio frequency channel mapping data application quality to the second communication device when one or two of the multiple items among the scatterer mass, the radio frequency channel quality, and the radio frequency channel mapping data application quality satisfy the first transmission condition. It can be understood that when one or two of the multiple items among the scatterer mass, the radio frequency channel quality, and the radio frequency channel mapping data application quality do not satisfy the first transmission condition, for example, when the multiple items include the scatterer mass and the radio frequency channel quality and the scatterer mass does not meet the first requirement, the radio frequency channel quality may not be transmitted; when the multiple items include the scatterer mass and the radio frequency channel mapping data application quality and the scatterer mass does not meet the first requirement, the radio frequency channel mapping data application quality may not be transmitted; when the multiple items include the radio frequency channel quality and the radio frequency channel mapping data application quality and the radio frequency channel quality does not meet the second requirement, the radio frequency channel quality may not be transmitted, which can reduce the system overhead.

[0009] In a possible implementation, the multiple items include the scatterer mass and the radio frequency channel quality, and satisfying the first transmission condition includes the scatterer mass meeting the first requirement.

[0010] Based on the above solution, when the mass of the scatterer meets the first requirement, it can be considered that the accuracy of the estimated position of the scatterer is relatively high. Therefore, the accuracy of the radio frequency channel mapping data generated based on the environmental reconstruction result including the scatterer will also be relatively high. Thus, the radio frequency channel quality can be evaluated with the second communication device, and accordingly, the radio frequency channel quality can be sent to the second communication device. If the mass of the scatterer does not meet the first requirement, the first communication device and the second communication device will not perform the process of radio frequency channel quality evaluation. Therefore, the first communication device will not send the radio frequency channel quality to the second communication device, which can reduce the system overhead.

[0011] In a possible implementation, multiple items include the mass of the scatterer and the application quality of the radio frequency channel mapping data. Meeting the first sending condition includes that the mass of the scatterer meets the first requirement.

[0012] Based on the above solution, when the mass of the scatterer meets the first requirement, it can be considered that the accuracy of the estimated position of the scatterer is relatively high. Therefore, the accuracy of the radio frequency channel mapping data generated based on the environmental reconstruction result including the scatterer will also be relatively high. Thus, the radio frequency channel mapping data can be used for perception-assisted communication. The first communication device can evaluate the application quality of the radio frequency channel mapping data with the second communication device, and accordingly, the application quality of the radio frequency channel mapping data can be sent to the second communication device. If the mass of the scatterer does not meet the first requirement, the first communication device and the second communication device will not perform the evaluation of the application quality of the radio frequency channel mapping data. Therefore, the first communication device will not send the application quality of the radio frequency channel mapping data to the second communication device, which can reduce the system overhead.

[0013] In a possible implementation, multiple items include the radio frequency channel quality and the application quality of the radio frequency channel mapping data. Meeting the first sending condition includes that the radio frequency channel quality meets the second requirement.

[0014] Based on the above solution, when the radio frequency channel quality meets the second requirement, it can be considered that the accuracy of the radio frequency channel mapping data is relatively high. Thus, the radio frequency channel mapping data can be used for perception-assisted communication. The first communication device can evaluate the application quality of the radio frequency channel mapping data with the second communication device, and accordingly, the application quality of the radio frequency channel mapping data can be sent to the second communication device. If the radio frequency channel quality does not meet the second requirement, the first communication device and the second communication device will not perform the evaluation of the application quality of the radio frequency channel mapping data. Therefore, the first communication device will not send the application quality of the radio frequency channel mapping data to the second communication device, which can reduce the system overhead.

[0015] In a possible implementation, multiple items include the mass of the scatterer, the radio frequency channel quality, and the application quality of the radio frequency channel mapping data. Meeting the first sending condition includes that the mass of the scatterer meets the first requirement and the radio frequency channel quality meets the second requirement.

[0016] Based on the above solution, when the scatterer mass meets the first requirement and the RF channel quality meets the second requirement, it can be considered that the accuracy of the RF channel mapping data is relatively high. Therefore, the RF channel mapping data can be used for sensing-assisted communication, and the first communication device can evaluate the application quality of the RF channel mapping data with the second communication device, so as to send the application quality of the RF channel mapping data to the second communication device. If the scatterer mass does not meet the first requirement, the first communication device and the second communication device will not evaluate the RF channel quality and the application quality of the RF channel mapping data, and the first communication device will not send the RF channel quality and the application quality of the RF channel mapping data to the second communication device, which can reduce the system overhead. If the scatterer mass meets the first requirement but the RF channel quality does not meet the second requirement, the first communication device and the second communication device will not evaluate the application quality of the RF channel mapping data, and the first communication device will not send the application quality of the RF channel mapping data to the second communication device, which can reduce the system overhead.

[0017] In a possible implementation, before the first communication device sends the RF channel quality, if the scatterer mass does not meet the first requirement, after adjusting the scatterer mass to meet the first requirement, it sends the RF channel quality.

[0018] Based on the above solution, when the scatterer mass does not meet the first requirement, the first communication device can not send the RF channel quality, thereby reducing the system overhead, and send the RF channel quality after adjusting the scatterer mass to meet the first requirement to evaluate the accuracy of the generated RF channel mapping data.

[0019] In a possible implementation, before the first communication device sends the application quality of the RF channel mapping data, if the scatterer mass does not meet the first requirement, after adjusting the scatterer mass to meet the first requirement, it sends the application quality of the RF channel mapping data. Or, before sending the application quality of the RF channel mapping data, if the RF channel quality does not meet the second requirement, after adjusting the RF channel quality to meet the second requirement, it sends the application quality of the RF channel mapping data.

[0020] Based on the above solution, when the scatterer mass does not meet the first requirement or the scatterer mass does not meet the second requirement, the first communication device can not send the application quality of the RF channel mapping data, thereby reducing the system overhead, and use the RF channel mapping data for sensing-assisted communication after adjusting the scatterer mass to meet the first requirement or adjusting the RF channel quality to meet the second requirement to evaluate the application quality of the generated RF channel mapping data.

[0021] In a possible implementation, the application quality of the radio frequency channel mapping data does not meet the third requirement. The first communication device receives the second radio frequency channel mapping data, and the parameters included in the second radio frequency channel mapping data are different from those included in the first radio frequency channel mapping data and / or the compression method of the second radio frequency channel mapping data is different from that of the first radio frequency channel mapping data.

[0022] Based on this solution, when the application quality of the radio frequency channel mapping data does not meet the third requirement, it can be considered that the accuracy of the radio frequency channel mapping data is relatively low. This problem may be caused by the second communication device compressing the radio frequency channel mapping data and sending it to the first communication device, and then the first communication device decompresses it in order to reduce the transmission pressure, or it may also be caused by the parameters selected by the second communication device when generating the radio frequency channel mapping data, such as inaccurate communication links. Therefore, the second communication device can adjust the parameters selected when generating the radio frequency channel mapping data and / or the compression method of the radio frequency channel mapping data to improve the accuracy and / or reception performance of the radio frequency channel mapping data.

Among them, the second communication device can be a terminal device or a network device. Taking the execution by the second communication device as an example for illustration. In this method, the second communication device sends a quality measurement request. The second communication device receives one or more of the scatterer quality, the radio frequency channel quality, and the application quality of the radio frequency channel mapping data. Among them, the scatterer quality characterizes the accuracy of the positions of the scatterers included in the first radio frequency channel mapping data, the radio frequency channel quality characterizes the deviation between the channel state measurement value and the channel state prediction value included in the first radio frequency channel mapping data, and the application quality of the radio frequency channel mapping data characterizes the usage quality of using the first radio frequency channel mapping data.

[0075] To facilitate the understanding of the technical solutions provided by the embodiments of the present application, the following introduces the technical terms involved in the embodiments of the present application.

[0076] 1) Sensing, also known as wireless sensing, refers to emitting electromagnetic energy into space. By receiving the radio waves reflected by the objects existing in the space, the information of the objects can be calculated. For example, parameters such as position, direction, height, speed, size, movement path, etc., and the internal and external shapes and structures of the objects can be detected. By exploring the transmission, echo, reflection, and scattering of radio waves, the physical world can be sensed and better understood. As one of the electromagnetic wave sensing technologies, due to its penetrability and security, wireless sensing technology can be an important alternative technology in aspects such as security inspection, detection of concealed objects, and environmental reconstruction, as Figure 1 shown.

[0077] 2) The communication-sensing integrated system, also known as the communication-perception integrated system, refers to the integrated use of electromagnetic signals for communication and electromagnetic signals for sensing. In the past, the main targets of active positioning were terminal devices capable of emitting electromagnetic waves. For example, mobile phones, vehicles, Internet of Things (IoT) devices, etc. The targets of virtual environment reconstruction further include passive objects, such as buildings, urban facilities (billboards, bridges, etc.), traffic conditions (vehicles, bicycles), etc. By receiving electromagnetic wave signals propagated through the spatial environment, the composition of the spatial environment is solved, and through the detection and reconstruction of the virtual environment (active and passive objects and devices), further auxiliary positioning or improvement of sensing-assisted communication performance is achieved. Network devices and terminal devices are the main devices for virtual environment reconstruction. The quality of sensing is related to communication-sensing resources, space, time, frequency band, power consumption, and stations. Among them, stations can refer to network devices, terminal devices, or wireless terminal access devices (customer premise equipment, CPE), etc.

[0078] For example, space can include the number of beams, which can affect the sensing angle range. Time includes the sensing symbol length, which can affect the sensing azimuth accuracy. The frequency band includes the sensing bandwidth, which can affect the sensing range accuracy in the distance direction. Power consumption includes the sensing signal power, which can affect the sensing distance range. The communication capacity that the station can include can affect the sensing fusion accuracy.

[0079] According to whether the transceiver ends of the sensing signals share the same station or different stations, it can be divided into monostatic, bi-static, and multi-static. Multi-static is generally a hybrid system composed of monostatic and bi-static, and two typical communication-sensing integrated system architectures Figure 2A and Figure 2B are shown. It can be understood that monostatic sensing can also be called single-station sensing, that is, sensing is performed through one station. Similarly, multi-static sensing can also be called multi-station sensing, that is, sensing is performed through two or more stations. Similarly, multi-static sensing can be called multi-station sensing.

[0080] Figure 2AA monostatic communication and sensing integrated system is shown. In the monostatic communication and sensing integrated system, the sensing transmitter and the sensing receiver are at the same location, and the sensing signal can use data payload, so this sensing function does not consume communication resources. At the same time, due to the same transceiver source, there are no problems of non-ideal factors such as synchronization. Its sensing algorithm complexity, estimation accuracy, etc. are better. In the monostatic environment reconstruction, because of the self-transmitting and self-receiving, the angle range of the signal that can be detected is strongly related to the incident angle of the environment. For the reflected signal of an object, as the incident angle increases, it undergoes rapid fading. That is, the viewing angle range of the monostatic environment reconstruction is greatly affected by the material of the target object and its placement angle. Due to the use of monostatic sensing, most of the components of its echo signal are single bounce, which satisfies the radar assumption. When solving the environmental space, the problem of ill-conditioned equations is small, and the solution accuracy of the space environment is high.

[0081] Figure 2B A bistatic sensing and communication integrated system is shown. In the bistatic sensing and communication integrated system, the sensing receiver and the sensing transmitter are at different locations, and the sensing signal needs to use a dedicated pilot or a known signal, so this sensing function consumes communication resources. At the same time, due to different transceiver sources, there are problems of non-ideal factors such as synchronization and phase noise. Its sensing algorithm complexity, estimation accuracy, etc. are poor, and a more complex calibration algorithm is required to handle them. In bistatic sensing, because of the self-transmitting and other-receiving, the environmental angle that can be detected is larger, and as the terminal moves, the sensing viewing angle has a large coverage. In addition, the components of its echo signal are rich, with a large number of multi-bounce paths (bounce greater than or equal to 2) and high power. In a richly scattering urban space, a large number of multi-bounce paths will introduce ill-conditioned equations, resulting in shadow spaces and incorrect solutions when solving the virtual environment.

[0082] The technical solution of the embodiment of the present application can be applied to New Radio (NR) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, next-generation wireless communication systems such as 6G, etc., without limitation here.

[0083] Figure 3 It is a schematic diagram of the architecture of the communication system 1000 to which the embodiment of the present application is applied. As Figure 3 shown, the communication system includes a radio access network 100. Among them, the radio access network 100 may include at least one network device (such as Figure 3in 110a and / or 110b), may further include at least one terminal device (such as Figure 3 at least one of 120a - 120j in). The terminal device is connected to the access network device wirelessly, and the access network device is connected to the core network device wirelessly or by wire. The terminal devices can be connected to each other, and the network devices can be connected to each other, either by wire or wirelessly. Figure 3 This is just a schematic diagram. The communication system may further include other network devices, such as wireless relay devices and wireless backhaul devices, which are not drawn Figure 3 in the figure.

[0084] A network device is a network - side device with wireless transceiver functions. The network device can be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices, called a RAN device. For example, the network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next - generation base station (gNB) in a 5th - generation (5G) mobile communication system, a next - generation base station in a 6th - generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it can also be a module or unit that completes some functions of the base station. For example, it can be a central unit (CU) or a distributed unit (DU). Here, the CU completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete some or all of the functions of the physical layer. For specific descriptions of the above - mentioned protocol layers, reference can be made to the relevant technical specifications of the 3rd - generation partnership project (3GPP). The network device can be a macro - base station (such as Figure 3 110a in), or a micro - base station or an indoor station (such as Figure 3In 110b), it can also be a relay node, a donor node, etc. Embodiments of the present application do not limit the specific technologies and specific device forms adopted by network devices.

[0085] In another possible scenario, multiple RAN nodes cooperate to assist a terminal in achieving wireless access, and different RAN nodes respectively implement partial functions of a base station. For example, an RAN node can be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0086] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, the CU can also be called an O-CU (open CU), the DU can also be called an O-DU, the CU-CP can also be called an O-CU-CP, the CU-UP can also be called an O-CU-UP, and the RU can also be called an O-RU. For ease of description, in the present application, the CU, the CU-CP, the CU-UP, the DU, and the RU are taken as examples for description. Any one of the CU (or CU-CP, CU-UP), the DU, and the RU in the present application can be implemented through a software module, a hardware module, or a combination of a software module and a hardware module.

[0087] The terminal device is a user-side device with wireless transceiver functions. The terminal device can also be referred to as a user equipment (UE), mobile station, mobile terminal, etc. The terminal device can be widely applied 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, remote medical treatment, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, etc. The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver functions, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0088] The network device and the terminal device can be fixed in position or movable. The network device and the terminal device can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites in the air. The embodiments of this application do not limit the application scenarios of the network device and the terminal device.

[0089] The roles of the network device and the terminal device can be relative. For example, Figure 3 the helicopter or drone 120i in can be configured as a mobile network device. For the terminal devices 120j that access the radio access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between network devices. At this time, relative to 110a, 120i is also a network device. Therefore, both the network device and the terminal device can be uniformly referred to as communication devices. Figure 3 The 110a and 110b in can be referred to as communication devices with network device functions. Figure 3 The 120a - 120j in can be referred to as communication devices with terminal device functions.

[0090] In the embodiments of the present application, the functions of the network device may also be executed by a module (such as a chip) in the network device, or may be executed by a control subsystem including the functions of the network device. The control subsystem including the functions of the network device here may be a control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device may also be executed by a module (such as a chip or a modem) in the terminal device, or may be executed by a device including the functions of the terminal device. In the following, an example is described in which the functions of the terminal device are executed by the terminal and the functions of the network device are executed by the base station.

[0091] Currently, using the environmental information obtained by sensing to obtain higher spectral efficiency through sensing-assisted communication, or to obtain a more robust, resilient, and easily recoverable network has become the main topic of sensing-assisted communication. Sensing-assisted channel prediction, sensing-assisted positioning, etc. are important topics in sensing-assisted communication, and the environmental information obtained by sensing is used to predict radio frequency channel conditions such as communication and positioning. The radio frequency channel conditions can be predicted through the obtained environmental information, and the predicted radio frequency channel conditions can be referred to as radio frequency channel mapping maps, radio frequency channel mapping data, or radio frequency data, etc.

[0092] However, there may be certain errors in the radio frequency channel mapping data. Such errors may be caused by the difference between the environmental information obtained by sensing and the real environmental information or electromagnetic environment, or may be caused by the difference between the model and the real propagation mode when generating the radio frequency channel mapping data based on the obtained environmental reconstruction results, or may be the loss caused by compressing and then transmitting the radio frequency channel mapping data to reduce communication pressure and then expanding it. Therefore, whether the radio frequency channel mapping data is accurate will affect the results of services such as sensing-assisted channel prediction and sensing-assisted positioning.

[0093] In view of this, the embodiments of the present application provide a method for evaluating radio frequency data. In this method, the first communication device receives a quality measurement request, and based on the quality measurement request, sends one or more of the scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality. Among them, the scatterer quality characterizes the accuracy of the positions of the scatterers included in the first radio frequency channel mapping data, the radio frequency channel quality characterizes the deviation between the channel state measurement value and the channel state prediction value included in the first radio frequency channel mapping data, and the radio frequency channel mapping data application quality characterizes the usage quality of using the first radio frequency channel mapping data. Based on this solution, the first communication device can determine one or more of the scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality based on the quality measurement request, so as to evaluate whether the radio frequency channel mapping data can be applied to sensing-assisted communication such as sensing-assisted channel prediction and sensing-assisted positioning, so as to improve the performance of sensing-assisted communication.

[0094] To facilitate the understanding of the technical solution provided by the embodiments of the present application, the following introduces the method for obtaining radio frequency channel mapping data in the embodiments of the present application.

[0095] In a communication system, wireless sensing technology is used to obtain environmental information to assist in channel prediction, positioning, beamforming, etc., thereby improving the quality of communication services. Among them, the process of forming a radio frequency channel mapping map through wireless sensing technology for prediction is called radio frequency mapping (RF mapping). The map obtained by RF mapping is called a radio frequency channel map. The data corresponding to the radio frequency channel map is called radio frequency channel mapping data.

[0096] Referring to Figure 4A , a physical environment map is shown. Figure 4A In, the dashed line can represent a road. In the embodiments of the present application, the radio frequency channel mapping data of the physical environment shown in Figure 4A can be obtained. In this physical environment, there can be multiple sensing communication nodes, such as base stations, terminals, transmission and receiving points (TRPs), or customer premise equipment (CPEs), etc. The sensing communication nodes can transmit electromagnetic waves, radar signals, etc. to obtain an environmental reconstruction result, as shown in Figure 4B . For example, the sensing communication nodes can transmit electromagnetic waves or radar signals and receive echo signals, so as to obtain the scatterer information in the physical environment. In a possible situation, each of the sensing communication nodes can interact the obtained scatterer information, so as to obtain a higher-precision environmental reconstruction result in a larger range, as shown in Figure 4B . Any one of the above-mentioned multiple sensing communication nodes can divide the physical environment map into multiple regions, and each region is regarded as a location. For the convenience of description, any one of the above-mentioned sensing communication nodes is referred to as a target sensing communication node. For example, the target sensing communication node can divide the physical environment map into multiple rectangular regions or grids, as shown in Figure 4C . For another example, the target sensing communication node can divide the physical environment map into different circular regions (not shown in the figure). For another example, the target sensing communication node can divide the physical environment map into different hexagonal regions or honeycomb regions (not shown in the figure), etc. The present application does not make specific limitations. It can be understood that when the target sensing communication node divides the physical environment map into multiple regions, the resolution of the regions can be predefined or preconfigured by the protocol. For example, the physical environment map can be divided into multiple regions according to a resolution of every 5m, 10m, etc. The present application does not make specific limitations.

[0097] In this article, the case where the target sensing communication node divides the physical environment map into multiple grids is taken as an example for illustration.

[0098] The target-aware communication node may assume that there is a terminal at each location and simulate the transmission paths from the base station to the terminals at each location, as Figure 4C shown. It can be understood that the transmission paths may include the direct transmission paths from the base station to the terminals, or may also include the transmission paths that reach the terminals after being reflected by the scatterers. For example, the target-aware communication node may use the mirror line-of-sight tracking algorithm to obtain the transmission paths between the base station and the terminals at each location. The target-aware communication node may calculate the predicted channel state values for each location based on the simulated transmission paths, as Figure 4D shown. Exemplarily, the target-aware communication node may calculate the predicted channel state values of the transmission paths from the base station through the environment to the terminals at each location by using ray tracing tools, electromagnetic calculation tools, or simple simulation tools based on specular reflection, etc. In addition, the target-aware communication node may obtain the scatterer information associated with each location, that is, the information of the scatterers passed by from the base station to the terminals at each location. In this way, the radio frequency channel mapping data can be obtained.

[0099] It should be noted that the above method for obtaining the radio frequency channel mapping data is only shown as an example and does not constitute a limitation on the method for obtaining the radio frequency channel mapping data.

[0100] In a possible case, the radio frequency channel mapping data involved in the embodiments of the present application may include the location information of each of the foregoing locations, the predicted channel state values of each location, and the scatterer information associated with each location. Among them, the location information may be indicated by using relative locations, such as the distance or angle relative to a certain base station, or may also be indicated by using absolute locations, such as longitude and latitude information. Alternatively, the location information may be indicated by a grid number.

[0101] Optionally, if the location information is indicated by a grid number, the radio frequency channel mapping data may further include grid setting information, and the grid setting information may indicate the starting position of the grid and / or the resolution of the grid. Among them, the starting position of the grid may indicate the starting position when dividing the grid, and may be indicated by a relative location or an absolute location. The resolution of the grid may indicate the scale used when dividing the grid. It can be understood that the resolution of the grid may also not be indicated and a default resolution may be adopted.

[0102] Among the multiple sensing communication nodes existing in the above physical environment, a base station may be included. In a possible scenario, the processing operations of the base station may be executed by the CU, and the transceiver operations of the base station may be executed by the DU or RU. For example, the CU may generate electromagnetic waves for sensing, and the CU may send the electromagnetic waves to the DU. The DU may send the electromagnetic waves, or the DU may send the electromagnetic waves to the RU for the RU to send. Similarly, the DU may receive the electromagnetic waves and send the electromagnetic waves to the CU. The CU determines the scatterer information or scatterer group information to determine the environmental reconstruction result. Optionally, the RU may receive the electromagnetic waves and send the electromagnetic waves to the DU.

[0103] In another possible scenario, the processing operations of the base station may be executed by the CU-CP, and the transceiver operations of the base station may be executed by the DU or RU. For example, the CU-CP may generate electromagnetic waves for sensing, and the CU-CP may send the electromagnetic waves to the DU. The DU may send the electromagnetic waves, or the DU may send the electromagnetic waves to the RU for the RU to send. Similarly, the DU may receive the electromagnetic waves and send the electromagnetic waves to the CU-CP. The CU-CP determines the scatterer information or scatterer group information to determine the environmental reconstruction result. Optionally, the RU may receive the electromagnetic waves and send the electromagnetic waves to the DU.

[0104] Similarly, the above target sensing communication node may be a base station, or a terminal, or a TRP. If the target sensing communication node is a base station, in a possible scenario, the processing operations of the base station may be executed by the CU, and the transceiver operations of the base station may be executed by the DU or RU. For example, the CU may divide the physical environment map into multiple regions, each region serving as a location, and determine the radio frequency channel mapping data for each location. The CU may send the radio frequency channel mapping data to the DU, and the DU may send the radio frequency channel mapping data to the terminal or the core network. Optionally, the DU may send the radio frequency channel mapping data to the RU, and the RU may send the radio frequency channel mapping data to the terminal or the core network.

[0105] In another possible scenario, the processing operations of the base station may be executed by the CU-CP, and the transceiver operations of the base station may be executed by the DU or RU. For example, the CU-CP may divide the physical environment map into multiple regions, each region serving as a location, and determine the radio frequency channel mapping data for each location. The CU-CP may send the radio frequency channel mapping data to the DU, and the DU may send the radio frequency channel mapping data to the terminal or the core network. Optionally, the DU may send the radio frequency channel mapping data to the RU, and the RU may send the radio frequency channel mapping data to the terminal or the core network.

[0106] In the O-RAN scenario, the operations performed by the above CU can be executed by the O-CU, the operations performed by the DU can be executed by the O-DU, the operations performed by the RU can be executed by the O-RU, and the operations performed by the CU-CP can be executed by the O-CU-CP.

[0107] In this application, the radio frequency channel map can indicate information in the following two aspects:

[0108] On the one hand, the radio frequency channel map corresponds to a certain geographical area and is used to indicate the geographical locations and area sizes of multiple regions divided within this geographical area.

[0109] Among them, the geographical area can be an area within a certain range in the real physical world. For example, the above geographical area can be characterized by longitude, latitude, and altitude. For instance, the starting point is denoted as (x_0, y_0, z_0), and it is an outdoor scene of 100m×100m with this starting point as the reference.

[0110] Among them, the multiple regions can be regions obtained by dividing the geographical area in a certain manner. For example, for the above geographical area of 100m×100m, it is divided in the manner of 1m×1m to obtain 100×100 regions. Among them, each region is 1m×1m.

[0111] It is easy to understand that in this application, the regions involved in the radio frequency channel map (i.e., the regions obtained by dividing the above geographical area in a certain manner) can have at least one of the following attributes: shape, size, area, geographical location, etc.

[0112] In this application, the shapes, contours, sizes, radii, and areas of different regions are the same. The geographical locations of different regions are different. There is no overlap between different regions.

[0113] In a possible implementation manner, the shape of the region can be a square, or other shapes, such as a rectangle, a trapezoid, a triangle, etc. Or, the shape of the region can also be an irregular shape, without limitation.

[0114] Exemplarily, the shape of the region can be defined by the protocol, or can be defined by the network device. The region shapes defined by different network devices can be the same or different. The same network device can also define multiple region shapes. Similarly, the size, radius, and area of the region can also be defined by the protocol, or can be defined by the network device. The region sizes, radii, and areas defined by different network devices can be the same or different. The same network device can also define multiple region sizes, multiple region radii, or multiple region areas.

[0115] In a possible implementation, multiple regions can be indexed (such as numbered) to identify different regions.

[0116] In a possible scenario, the radio frequency channel map includes multiple grids, and the multiple grids correspond to the multiple regions one by one. It is easy to understand that in this application, the grids involved in the radio frequency channel map can have at least one of the following attributes: shape, size, area, etc. Among them, the shape of the grid can be consistent with the shape of the corresponding region of the grid. The size of the grid has a certain ratio to the size of the corresponding region of the grid. The area of the grid has a certain ratio to the area size of the corresponding region of the grid. Among them, the size of the grid can also have other descriptions, such as resolution.

[0117] In a possible implementation, if the relevant results of the environmental reconstruction result obtained by the sensing communication node are inaccurate, for example, when the position accuracy of the scatterer or the scatterer group is relatively low, the accuracy of the radio frequency channel mapping data obtained based on the environmental reconstruction result will also be relatively low. Therefore, in the embodiments of this application, the quality of the scatterer can be evaluated. It can be understood that the scatterer quality can characterize the accuracy of the position of the scatterer or the scatterer group. Hereinafter, for the sake of convenience of description, the scatterer group and the scatterer are collectively referred to as the scatterer. It can be understood that the scatterer in the following text can also be replaced by the scatterer group.

[0118] Refer to Figure 5 , which shows an exemplary flowchart of a method for evaluating the quality of a scatterer, and may include the following operations. In this method, the first communication device in the aforementioned sensing communication node can initiate a scatterer quality evaluation to the second communication device in the sensing communication node. Figure 5 In, taking the first communication device as the base station and the second communication device as the terminal as an example for illustration.

[0119] S501: The base station sends a quality measurement request to the terminal.

[0120] Correspondingly, the terminal receives the quality measurement request from the base station.

[0121] For example, the base station can send a scatterer quality measurement request to the terminal. Figure 5 In the illustrated embodiment, the base station can be based on Figure 4A and Figure 4B the manner described to obtain the environmental reconstruction result.

[0122] In a possible scenario, the environmental reconstruction result or the radio frequency channel mapping data can be stored in the session management function (SMF) or the location management function (LMF) in the base station or the core network device. If the environmental reconstruction result or the radio frequency channel mapping data is stored in the LMF or SMF, the scatterer quality assessment can be initiated by the SMF or LMF. For example, the SMF or LMF can send a quality measurement request, such as a scatterer quality measurement request, to the base station, and the base station can execute S501.

[0123] It should be noted that the session management function network element and the location management function network element in the embodiments of the present application can be network elements with session management functions and location management functions respectively. For the convenience of description, the session management function network element and the location management function network element will be referred to as SMF and LMF respectively in the subsequent description of the present application. It should be noted that in future communications, the session management function network element and the location management function network element can still be referred to as SMF and LMF, or there may be other names, which are not limited in the present application.

[0124] In a possible implementation manner, the base station can determine the terminal associated with the scatterer and send a quality measurement request to the associated terminal. For example, assume that the base station wants to evaluate the quality {Q n , Q s1 , …, Q s2} of the scatterers {P1, P2, …, P sn} associated with the first location. Then the base station can determine the terminal at the first location and send a quality measurement request to the terminal at the first location.

[0125] Optionally, the quality measurement request may include scatterer information, such as the identification information of the scatterer and / or the estimated position of the scatterer, etc. It can be understood that the estimated position of the scatterer can be understood as the position of the scatterer obtained by the perception communication node based on the echo signal in Figure 4A .

[0126] S502: The terminal sends the scatterer quality to the base station.

[0127] Correspondingly, the base station receives the scatterer quality from the terminal.

[0128] In a possible scenario, the terminal can obtain the true value of the position of the scatterer. For example, the terminal can obtain information about the position of the scatterer in the map based on the map of the real physical environment and regard it as the true value of the position of the scatterer, that is, the real position. The terminal can determine the scatterer quality based on the true value of the position of the scatterer and the estimated position of the scatterer. For example, the terminal can calculate the difference, variance, or mean square difference between the true value of the position of the scatterer and the estimated position of the scatterer. The terminal can regard the obtained difference, variance, or mean square difference as the scatterer quality, or the terminal can determine the scatterer quality corresponding to the difference, variance, or mean square difference, that is, the terminal can quantify the scatterer quality based on the difference, variance, or mean square difference.

[0129] In another possible scenario, the terminal can obtain the position of the anchor point. For example, the position of a certain anchor point, such as the position of a building, the position of a street lamp, or the position of a street, can be stored in the terminal, where the building, street lamp, or street can be regarded as an anchor point. The terminal can estimate the position of the scatterer based on the position of the anchor point. The terminal can determine the scatterer quality based on the position of the scatterer estimated through the position of the anchor point and the estimated position of the scatterer. Reference can be made to the relevant descriptions above, and details will not be elaborated here.

[0130] In yet another possible scenario, the terminal can obtain the position of the scatterer obtained through long-term cumulative measurements. For example, the terminal can obtain the position of the scatterer measured over a period of time, such as one year, one month, or one week. The terminal can calculate the average value of these. The terminal can determine the quality of the scatterer based on this average value and the estimated position of the scatterer. Reference can be made to the relevant descriptions above, and details will not be elaborated here.

[0131] Optionally, in S502, the terminal can send the true value of the position of the scatterer, the position of the anchor point, or the average value of the position of the scatterer obtained through long-term cumulative measurements to the base station. The base station, or LMF, or SMF can determine the scatterer quality based on the true value of the position of the scatterer, the position of the anchor point, or the average value of the position of the scatterer obtained through long-term cumulative measurements from the terminal and the aforementioned estimated position of the scatterer.

[0132] It should be noted that through S501 and S502, multiple scatterer qualities may be obtained, such as the quality {Q n},Q s1 ,…,Q s2} of the scatterers {P1, P2, …, P sn} associated with the first position. The base station can be based on the quality {Q n ,Q s1 ,…,Q s2 ,…,Q sn}Determine the scatterer mass at the first position. For example, the base station can determine the average value of {Q s1 ,Q s2 ,…,Q sn} and use this average value as the scatterer mass at the first position. Among them, the scatterer mass Q s at the first position can satisfy the following formula (1).

[0133]

[0134] Among them, n represents the number of scatterers associated with the first position, and Q si represents the mass of the i-th scatterer among the n scatterers.

[0135] In a possible implementation, if the scatterer mass at the first position does not meet the first requirement, it can be considered that the scatterer mass at the first position is poor or the estimated position of the scatterer is inaccurate. The base station can restart the process of obtaining the environmental reconstruction result. For example, the base station can schedule sensing resources based on the scatterer mass obtained this time. The sensing communication node shown in Figure 4A emits electromagnetic waves or radar signals based on the scheduled sensing resources, receives the echo signals, obtains the environmental reconstruction result, and the base station can continue to execute S501 and S502 until the scatterer mass meets the first requirement.

[0136] It can be understood that the scatterer mass can be determined based on the aforementioned difference, variance or squared difference, or the scatterer mass can be the aforementioned difference, variance or squared difference itself. This application does not make specific limitations. Among them, if the scatterer mass does not meet the first requirement, it can be considered that the scatterer mass is greater than or equal to the scatterer mass threshold, or the scatterer mass is less than or equal to the scatterer mass threshold.

[0137] In a possible case, if the scatterer mass is determined based on the aforementioned difference, variance or squared difference, then the scatterer mass threshold can be values such as 1, 1.5 or 10%. In another possible case, if the scatterer mass is the difference, variance or squared difference itself, taking the variance as an example of the scatterer mass, the scatterer mass threshold can be values such as 0.1, 0.01 or 0.5. This application does not make specific limitations.

[0138] Based on the above solution, by Figures 4A to 4DAs shown, the radio frequency channel mapping data is obtained based on the environmental reconstruction result. If the scatterer quality meets the first requirement, it can be considered that the positions of the scatterers included in the environmental reconstruction result are relatively accurate. Therefore, the radio frequency channel mapping data obtained based on this environmental reconstruction result will also be relatively accurate, which can improve the accuracy of the radio frequency channel mapping data, and thus can improve the performance of perception-assisted communication based on the radio frequency channel mapping data. If the scatterer quality does not meet the first requirement, it can be considered that the scatterer quality does not meet the expectation. Then, the radio frequency channel mapping data obtained based on this environmental reconstruction result will not be accurate. Therefore, RF mapping can be performed without performing radio frequency channel quality assessment, and there is no need to send radio frequency channel quality to reduce the system overhead.

[0139] Optionally, when the base station re-initially obtains the environmental reconstruction result, the base station can adjust the sensing resources to improve the accuracy of the environmental reconstruction result. For example, the base station can adjust one or more of the transmission reception point (TRP), the number of antenna streams, the time-domain resources for sensing, the frequency-domain resource bandwidth, and the space.

[0140] In the embodiments of the present application, if the scatterer quality at the first position meets the first requirement, it means that the scatterer quality meets the expectation. Then, the base station can initiate an assessment of the radio frequency channel quality or an assessment of the application quality of the radio frequency channel mapping data. It can be understood that the radio frequency channel quality can represent the deviation between the channel state measurement value and the channel state prediction value included in the radio frequency channel mapping data, and the application quality of the radio frequency channel mapping data represents the usage quality of using the radio frequency channel mapping data. Hereinafter, the methods for assessing the radio frequency channel quality and the application quality of the radio frequency channel mapping data will be introduced separately through Figure 6 and Figure 7 to introduce the methods for assessing the radio frequency channel quality and the application quality of the radio frequency channel mapping data.

[0141] Refer to Figure 6 , which is an exemplary flowchart of a method for assessing radio frequency channel quality provided by the embodiments of the present application, and may include the following operations. In this method, the first communication device in the aforementioned perception communication node can initiate a radio frequency channel quality assessment to the second communication device in the perception communication node. Figure 6 In

[0142] S601: The base station sends a quality measurement request to the terminal.

[0143] Correspondingly, the terminal receives the quality measurement request from the base station. For example, the base station can send a radio frequency channel quality measurement request to the terminal.

[0144] Optionally, the quality measurement request in S601 may include radio frequency channel mapping data, such as through Figures 4A to 4DThe radio frequency channel mapping data obtained through the process shown. Alternatively, the radio frequency channel mapping data may have been sent to the terminal previously and stored in the terminal. In S601, the radio frequency channel mapping data may be stored in the base station or in the LMF or SMF in the core network device, and the base station may obtain the radio frequency channel mapping data and send it to the terminal.

[0145] In a possible scenario, the base station may send relevant data of K positions to the terminal, such as the location information of the K positions, the predicted values of the channel states of the K positions, and the scatterer information associated with the K positions, etc. The K positions include the first position where the terminal is located. Wherein, K is an integer greater than or equal to 1. For example, the base station may locate the terminal, or the terminal may send location information to the base station. In this way, the base station can determine the location where the terminal is located, and thus send the relevant data of the K positions to the terminal. Optionally, the radio frequency channel mapping data sent by the base station to the terminal may also include grid setting information.

[0146] In one example, the radio frequency channel mapping data involved in the embodiments of the present application may also include a reference radio frequency channel quality. It can be understood that the reference sensing quality may be an initial value, that is, the reference radio frequency channel quality determined based on the predicted value of the channel state, or the reference radio frequency channel quality may also be the radio frequency channel quality that has been updated through the Figure 6 embodiments shown. The radio frequency channel mapping data sent by the base station to the terminal may also include the reference radio frequency channel quality of the aforementioned K positions.

[0147] Optionally, for radio frequency channel quality assessment, the radio frequency channel mapping data sent by the base station to the terminal may also include configuration information of the measurement signal for radio frequency channel quality assessment, which may include one or more of the transceiver signal antenna port number (port), precoding information, and subcarrier configuration, etc. It can be understood that the above configuration information of the measurement signal may be Figures 4A to 4B the configuration information used by the sensing communication node to send electromagnetic waves when obtaining the environment reconstruction result shown, such as the transceiver antenna port number, precoding information, and subcarrier configuration, etc. This is to reduce the errors caused by differences in precoding information, subcarrier configuration, and transceiver antenna port number, so as to improve the accuracy of radio frequency channel quality.

[0148] In a possible implementation manner, S601 may be executed after the scatterer quality meets the first requirement. If the radio frequency channel mapping data is stored in the LMF or SMF, the LMF or SMF may send a quality measurement request to the base station, and the base station may execute S601.

[0149] S602: The base station sends a measurement signal to the terminal.

[0150] Correspondingly, the terminal receives a measurement signal from the base station.

[0151] For example, the measurement signal may be a downlink signal such as a channel state information (CSI)-reference signal (RS) or a positioning reference signal (PRS).

[0152] In a possible implementation, the terminal may obtain configuration information of the measurement signal. For example, the terminal may receive the configuration information of the measurement signal from the base station. For example, the base station may send a system message, and the terminal may receive the system message sent by the base station, and the system message may include the configuration information of the measurement signal.

[0153] It should be noted that when the base station sends a measurement signal, it may be sent according to the configuration information of the measurement signal. For example, the transceiver antenna port number, precoding information, and subcarrier configuration indicated in the configuration information of the measurement signal may be used to send the measurement signal. Similarly, when the terminal receives a measurement signal, it may receive it according to the configuration information of the measurement signal. For example, the transceiver antenna port number, precoding information, and subcarrier configuration indicated in the configuration information of the measurement signal may be used to receive the measurement signal.

[0154] The terminal may measure the measurement signal to obtain a channel state measurement value. For example, the terminal may measure the measurement signal to obtain the channel state information (CSI), power delay profile (PDP), call reference identifier (CRI), channel impulse response (CIR), rank indicator (RI), channel quality indicator (CQI), precoding matrix indicator (PMI), or layer indicator (LI) of the measurement signal, etc., which are not specifically limited in this application. The terminal may determine the radio frequency channel quality of the first location based on the channel state measurement value and the channel state prediction value of the first location. For example, the terminal may determine the correlation between the channel state measurement value and the channel state prediction value, so as to determine the radio frequency channel quality, which will be introduced below.

[0155] For example, the channel state prediction value of the first location included in the radio frequency channel mapping data is composed of R i elements, indicating at the first location (xi , y i , z i ) The multipath components predicted by the environment at a certain location are represented by formula (2):

[0156] R i = {(Power1, Delay1, AOX1), (Power2, Delay2, AOX2), …, (Power k , Delay k , AOX k )} Formula (2)

[0157] The terminal can measure the measurement signal and also determine the measurement result, which is represented by formula (3):

[0158]

[0159] Among them, the first position where the terminal is located can be represented by (x ue , y ue , z ue ). Optionally, when the positioning ability or positioning accuracy of the terminal is relatively good, for example, when the positioning quality exceeds a preset threshold, it indicates that the global positioning system (GPS) or the line of sight (LOS) condition is well evaluated. Therefore, (x ue , y ue , z ue ) and the corresponding R ue can be put into the recording stack to represent the true value information in reality.

[0160] It should be noted that the terminal can determine the correlation between R i and R ue through algorithms such as Euclidean distance, Manhattan distance, cosine similarity, Pearson correlation, and Jaccard similarity. Taking the Euclidean distance as an example for illustration.

[0161] The terminal can determine the correlation S i between R ue and R i = f(R i , R ue ), as the radio frequency channel quality, which is represented by formula (4):

[0162]

[0163] Among them, Q R can be used as the radio frequency channel quality.

[0164] S603: The terminal sends the radio frequency channel quality to the base station.

[0165] Correspondingly, the base station receives the radio frequency channel quality from the terminal.

[0166] In a possible scenario, in S603, the terminal can send the channel state measurement value to the base station. The base station, or the LMF, or the SMF can determine the radio frequency channel quality based on the channel state measurement value and the channel state prediction value. The method described in formulas (2) to (4) can be referred to, and the repeated parts will not be elaborated here.

[0167] In a possible implementation, if the radio frequency channel quality does not meet the second requirement, for example, when the radio frequency channel quality is greater than or equal to the radio frequency channel quality threshold, it means that the channel state prediction value does not meet the expectation, that is, the channel state prediction value is inaccurate. Then the base station can regenerate the radio frequency channel mapping data and restart the process of radio frequency channel quality assessment until the radio frequency channel quality meets the second requirement. Optionally, if the radio frequency channel quality does not meet the second requirement, when the base station regenerates the radio frequency channel mapping data, it can adjust the RF mapping data generation parameters to improve the accuracy of the radio frequency channel mapping data.

[0168] It can be understood that the radio frequency channel quality threshold can be set according to empirical values, such as it can be set to 10 dBM, etc. This application does not make specific limitations.

[0169] In the embodiments of this application, if the radio frequency channel quality meets the second requirement, for example, when the radio frequency channel quality is less than or equal to the radio frequency channel quality threshold, it means that the radio frequency channel quality meets the expectation. The base station can update the reference radio frequency channel quality of other positions associated with the scatterer associated with the first position, such as other positions except the first position, to the aforementioned radio frequency channel quality that meets the second requirement. Hereinafter, the other positions associated with the scatterer associated with the first position are referred to as the second position.

[0170] Refer to Figure 7 , which shows a schematic diagram of updating the perceived quality. As Figure 7 shown, the terminal can be at the first position ( Figure 7 the shaded rectangle shown in a of Figure 6 ). Through the Figure 7 embodiment shown in

[0171] In a possible scenario, assume that the scatterers associated with the first position include scatterer A and scatterer B, while the scatterers associated with the second position, such as position X, include scatterer A, scatterer B, and scatterer C. Then, the first communication device and the second communication device can determine the weights of each scatterer based on the contributions of scatterer A, scatterer B, and scatterer C to the predicted channel state value R i The radio frequency channel quality Q R at position X = the quality of scatterer A (radio frequency channel quality) * the weight of scatterer A + the quality of scatterer B (radio frequency channel quality) * the weight of scatterer B + the weight of scatterer C * the quality of scatterer C. Among them, the quality of scatterer C can be shown in the embodiment Figure 6 illustrated. The difference is that in the case of determining the quality of scatterer C, the communication device located at the position associated with scatterer C needs to execute the embodiment Figure 6 illustrated.

[0172] Based on the above solution, if the radio frequency channel quality meets the second requirement, it can be considered that the radio frequency channel quality meets the expectation. Since the radio frequency channel quality can reflect the quality of the communication link between the terminal and the base station, if the radio frequency channel quality meets the second requirement, it can be considered that the quality of the communication link between the terminal and the base station meets the expectation. As can be seen from the content Figures 4A to 4D illustrated, the communication link between the terminal and the base station can include a direct link or a transmission path after reflection by the scatterer. Therefore, when the radio frequency channel quality meets the expectation, it means that the positions of the scatterers are relatively accurate. Thus, based on the radio frequency channel quality, the radio frequency channel quality at the second position associated with the scatterer can be updated so that the radio frequency channel mapping data can be used for sensing-assisted communication, which can improve the service performance of the radio frequency channel mapping data.

[0173] In a possible implementation, if the radio frequency channel quality meets the second requirement, it means that the radio frequency channel quality meets the expectation, that is, the radio frequency channel qualities at the first position and the aforementioned second position are relatively accurate. Then, the relevant data at the first position and the aforementioned second position, such as one or more of the predicted channel state values at the first position and the aforementioned second position, the scatterer information associated with the first position and the aforementioned second position, or the radio frequency channel qualities at the first position and the aforementioned second position, can be used for sensing-assisted communication, and the protocol can enable the sensing-assisted communication of the relevant data at the first position in the radio frequency channel mapping data. For example, the base station can send the updated radio frequency channel mapping data to the terminal, such as the radio frequency channel mapping data with the reference radio frequency channel quality updated to the radio frequency channel quality in S602, and the terminal can use the relevant data at the first position and the aforementioned second position in the updated radio frequency channel mapping data for sensing-assisted communication.

[0174] In another possible implementation, if the scatterer mass meets the first requirement, it indicates that the scatterer mass meets the expectation, that is, the positions of the scatterers associated with the first position included in the environmental reconstruction result are relatively accurate. Therefore, the relevant data regarding the first position in the radio frequency channel mapping data generated based on this environmental reconstruction result is relatively accurate. Then, the relevant data of the first position and the aforementioned second position, such as one or more of the channel state prediction values of the first position and the aforementioned second position, the scatterer information associated with the first position and the aforementioned second position, or the radio frequency channel quality of the first position and the aforementioned second position, can be used for sensing-assisted communication, and the protocol can enable the sensing-assisted communication of the relevant data regarding the first position in the radio frequency channel mapping data. For example, the base station can send the updated radio frequency channel mapping data to the terminal, such as the radio frequency channel mapping data after updating the reference radio frequency channel quality to the radio frequency channel quality in S603, and the terminal can use the relevant data regarding the first position and the aforementioned second position in the updated radio frequency channel mapping data for sensing-assisted communication.

[0175] In yet another possible implementation, if the scatterer mass meets the first requirement and the radio frequency channel quality meets the second requirement, then the relevant data of the first position and the aforementioned second position, such as one or more of the channel state prediction values of the first position and the aforementioned second position, the scatterer information associated with the first position and the aforementioned second position, or the radio frequency channel quality of the first position and the aforementioned second position, can be used for sensing-assisted communication, and the protocol can enable the sensing-assisted communication of the relevant data regarding the first position and the aforementioned second position in the radio frequency channel mapping data. For example, the base station can send the updated radio frequency channel mapping data to the terminal, such as the radio frequency channel mapping data after updating the reference radio frequency channel quality to the radio frequency channel quality in S603, and the terminal can use the relevant data regarding the first position and the aforementioned second position in the updated radio frequency channel mapping data for sensing-assisted communication.

[0176] In a possible scenario, the radio frequency channel mapping data that the base station can send to the terminal may include the relevant data of M positions, and these M positions may include the first position and the aforementioned second position, where M is an integer greater than or equal to 1. For example, the radio frequency channel mapping data sent by the base station to the terminal may include the position information of M positions, the channel state prediction values of M positions, the scatterer information or scatterer group information associated with M positions. Optionally, the radio frequency channel mapping data sent by the base station to the terminal may also include the aforementioned grid setting information, indicating the starting position of the grid and / or the resolution of the grid. It can be understood that the M positions may be the same as or different from the aforementioned K positions.

[0177] In one example, the radio frequency channel mapping data sent by the base station to the terminal may also include, for example Figure 6The radio frequency channel quality shown. Optionally, the radio frequency channel mapping data sent by the base station to the terminal may further include the radio frequency channel mapping data application quality, and the radio frequency channel mapping data application quality may be based on Figure 8 The embodiment shown is determined.

[0178] Optionally, the radio frequency channel mapping data sent by the base station to the terminal may further include the configuration information of the measurement signal for evaluating the radio frequency channel quality, and may include one or more of the transceiver signal antenna port number (port), precoding information, subcarrier configuration, etc.

[0179] Exemplarily, in the embodiments of the present application, the radio frequency channel mapping data sent by the base station to the terminal may include the content shown in Table 1 below.

[0180] Table 1: An example of radio frequency channel mapping data

[0181]

[0182]

[0183] As shown in Table 1, the radio frequency channel mapping data sent by the base station to the terminal may include one or more of the configuration information of the measurement signal, grid setting information, location information, channel state prediction value, associated scatterer or scatterer group, and associated sensing quality. Hereinafter, each will be introduced.

[0184] 1. The configuration information of the measurement signal may include one or more of the transceiver signal antenna port number (port), precoding information, subcarrier configuration, etc.

[0185] It can be understood that the above configuration information of the measurement signal may be the configuration information used by the sensing communication node to send electromagnetic waves when obtaining the environmental reconstruction result, such as the transceiver antenna port number, precoding information, subcarrier configuration, etc.

[0186] 2. Location information, indicating the geographical location. Among them, the location information may use relative location, such as the distance or angle relative to a certain base station, etc., or may also use absolute location, such as longitude and latitude information. Or, the location information may be indicated by a grid number. In Table 1, the subscript i may be understood as the grid number.

[0187] 3. Grid setting information, indicating the starting position of the grid and / or the resolution of the grid.

[0188] Among them, the starting position of the grid may indicate the starting position when dividing the grid, and may be indicated by relative position or absolute position. The resolution of the grid may indicate the scale used when dividing the grid. It can be understood that the resolution of the grid may also not be indicated, and the default resolution may be adopted.

[0189] 4. The predicted value of the channel state can be indicated by multipath information, such as indicated by a power delay profile (PDP), a channel impulse response (CIR), etc. This predicted value of the channel state is Figures 4A to 4D calculated from the transmission paths of the target sensing communication node described in

[0190] to the terminals at each location through the base station. Figure 4B 5. Associated scatterer information or scatterer group information, which is the information of the scatterers or scatterer groups associated with the transmission paths when predicting the channel state of the estimated grid. In one possible case, the scatterer information may include the identifier of the scatterer and / or the position information of the scatterer. Among them, the position information of the scatterer can be indicated by the coordinate information of the grid or can also be indicated by the absolute position or relative position. Optionally, the scatterer information may further include acquisition time information, such as a timestamp, which represents

[0191] the time when the sensing communication node senses the scatterer at this timestamp. Figure 6 6. The radio frequency channel quality, which is the radio frequency channel quality corresponding to the grid and is equivalent to the quality of service of sensing accuracy. Optionally, the radio frequency channel quality corresponding to the grid may have an initial value, which can be set to a preset minimum value, or can be determined according to the acquisition time information of the scatterer information or scatterer group information. For example, the greater the time difference between the acquisition time information and the current time, the earlier the time for evaluating the radio frequency channel quality can be characterized, so the radio frequency channel quality may become inaccurate, and thus the initial value is lower. The smaller the time difference between the acquisition time information and the current time, the later the time for evaluating the radio frequency channel quality can be characterized, so the change in the radio frequency channel quality may not be significant, and thus the initial value is higher. The radio frequency channel quality can be updated through a measurement process as shown in

[0192] 7. The quality of application of radio frequency channel mapping data, which can also be called the quality of sensing-assisted communication, refers to the quality feedback of communication in the corresponding area, such as the first position, after using the current radio frequency channel mapping data, such as the radio frequency channel mapping data shown in Table 1, for sensing-assisted communication. Optionally, the quality of application of radio frequency channel mapping data can be updated through a measurement process of the quality of application of radio frequency channel mapping data as shown in Figure 8 as follows.

[0193] Refer to Figure 8, which is an exemplary flowchart of a method for evaluating the application quality of radio frequency channel mapping data provided by an embodiment of this application, may include the following operations. In this method, the first communication device in the aforementioned sensing communication node may initiate a radio frequency channel quality evaluation to the second communication device in the sensing communication node. Figure 8 Here, taking the first communication device as the base station and the second communication device as the terminal as an example for illustration.

[0194] S801: The base station sends a quality measurement request to the terminal.

[0195] Correspondingly, the terminal receives the quality measurement request from the base station.

[0196] In a possible situation, the above quality measurement request may be a radio frequency channel mapping data application request, used to request or indicate that the terminal performs sensing-assisted communication based on radio frequency channel mapping data, such as enabling the terminal to perform positioning, beamforming, or communication based on radio frequency channel mapping data.

[0197] In a possible implementation manner, S801 may be executed when the radio frequency channel quality meets the second requirement. If the radio frequency channel mapping data is stored in the LMF or SMF, then the LMF or SMF may send a quality measurement request to the base station when the radio frequency channel quality meets the second requirement, and the base station may execute S801.

[0198] Optionally, Figure 7 The following operation S802 may also be included in the illustrated embodiment.

[0199] S802: The terminal sends a quality measurement response to the base station.

[0200] Correspondingly, the base station receives the quality measurement response from the terminal.

[0201] In a possible situation, the quality measurement response may be a radio frequency channel mapping data application response, used to indicate that the terminal can perform sensing-assisted communication based on radio frequency channel mapping data, or used to indicate that the base station sends radio frequency channel mapping data. Optionally, the base station may send the quality measurement response to the LMF or SMF.

[0202] S803: The base station sends radio frequency channel mapping data to the terminal.

[0203] Correspondingly, the terminal receives the radio frequency channel mapping data from the base station.

[0204] For example, the base station may send radio frequency channel mapping data as shown in Table 1 to the terminal. The radio frequency channel mapping data may include relevant data for M positions, and the M positions may include a first position and the aforementioned second position. In a possible scenario, if the radio frequency channel mapping data is stored in the LMF or SMF, the LMF or SMF may send the radio frequency channel mapping data to the base station, and the base station may execute S803.

[0205] S804: The terminal performs sensing-assisted communication based on the radio frequency channel mapping data.

[0206] For example, the terminal may perform beamforming, positioning, or communication based on the radio frequency channel mapping data.

[0207] S805: The terminal sends the application quality of the radio frequency channel mapping data to the base station.

[0208] Correspondingly, the base station receives the application quality of the radio frequency channel mapping data from the terminal.

[0209] Among them, the terminal may determine the application quality of the radio frequency channel mapping data based on the quality of service (QoS) during the communication process, the acknowledgement (ACK) or non-acknowledgement (NACK) during the communication process, and the result of positioning as the confidence level. For example,

[0210] In a possible implementation, if the application quality of the radio frequency channel mapping data does not meet the third requirement, it can be considered that the application quality of the radio frequency channel mapping data of the radio frequency channel mapping data does not meet the expectation. This problem may be caused by the base station compressing the radio frequency channel mapping data and sending it to the terminal, and then the terminal decompressing it to reduce the transmission pressure, or it may also be caused by the parameters selected by the base station when generating the radio frequency channel mapping data, such as inaccurate communication links. Therefore, the base station can adjust the compression method of the radio frequency channel mapping data or the parameters selected when generating the radio frequency channel mapping data, such as the communication link, and send the adjusted radio frequency channel mapping data to the terminal. The terminal may perform sensing-assisted communication based on the adjusted radio frequency channel mapping data. If the application quality of the radio frequency channel mapping data meets the first requirement, it can be considered that the accuracy of the radio frequency channel mapping data is relatively high, and the terminal may continue to perform sensing-assisted communication based on the radio frequency channel mapping data.

[0211] It can be understood that the application quality of radio frequency channel mapping data can be determined based on the number of the foregoing ACKs, the number of NACKs, the positioning result, or QOS, or the application quality of radio frequency channel mapping data can be the number of ACKs, the number of NACKs, the positioning result, or QOS itself. The present application does not make specific limitations. Among them, if the application quality of radio frequency channel mapping data does not meet the third requirement, it can be considered that the application quality of radio frequency channel mapping data is greater than or equal to the radio frequency channel mapping data application quality threshold, or the application quality of radio frequency channel mapping data is less than or equal to the radio frequency channel mapping data application quality threshold.

[0212] In one possible case, if the application quality of radio frequency channel mapping data is determined based on the number of the foregoing ACKs, the number of NACKs, the positioning result, or QOS, then the application quality of radio frequency channel mapping data can be 1, or values such as 15%. In another possible case, if the application quality of radio frequency channel mapping data is the number of ACKs, the number of NACKs, the positioning result, or QOS itself, taking the application quality of radio frequency channel mapping data being the number of NACKs as an example, the radio frequency channel mapping data application quality threshold can be values such as 1, 2, or 3. The present application does not make specific limitations.

[0213] Based on the above solution, if the application quality of radio frequency channel mapping data does not meet the third requirement, it can be considered that the compression method of the radio frequency channel mapping data is incorrect, or the parameters selected when generating the radio frequency channel mapping data are inaccurate. Then, the performance of the terminal for perception-assisted communication based on the radio frequency channel mapping data is low. Therefore, the base station can adjust the compression method of the radio frequency channel mapping data or the parameters selected when generating the radio frequency channel mapping data in order to improve the performance of perception-assisted communication.

[0214] It should be noted that in the embodiments of the present application Figure 5 、 Figure 6 and Figure 8 can be implemented as separate embodiments, or any two of them can be combined, or all three embodiments can be combined as one embodiment. Hereinafter, a description will be given in combination with Figure 9 for introduction.

[0215] Referring to Figure 9 , which is an exemplary flowchart of a radio frequency data evaluation method provided by an embodiment of the present application, may include the following operations. In this method, the first communication device in the foregoing perception communication node may initiate a radio frequency channel quality assessment to the second communication device in the perception communication node. Figure 9 Here, the first communication device is taken as the base station and the second communication device is taken as the terminal for illustration.

[0216] S901: The base station sends a quality measurement request to the terminal.

[0217] Correspondingly, the terminal receives a quality measurement request from the base station.

[0218] For example, the base station sends one or more of a scatterer quality measurement request, a radio frequency channel quality measurement request, or a radio frequency channel mapping data application request to the terminal, which can be implemented with reference to S501, S601, or S801.

[0219] In a possible scenario, if the radio frequency channel mapping data is stored by the LMF or SMF, the LMF or SMF in S901 can send a quality measurement request to the base station, and the base station can send a quality measurement request to the terminal.

[0220] S902: The terminal sends one or more of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the base station.

[0221] Correspondingly, the terminal receives one or more of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality from the base station.

[0222] For example, the terminal can send one of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the base station. Also for example, the terminal can send multiple ones of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the base station. Exemplarily, the terminal can send the scatterer quality and the radio frequency channel quality to the base station; the terminal can send the scatterer quality and the radio frequency channel mapping data application quality to the base station; the terminal can send the radio frequency channel quality and the radio frequency channel mapping data application quality to the base station; the terminal can send the scatterer quality, the radio frequency channel quality, and the radio frequency channel mapping data application quality to the base station.

[0223] In a possible implementation manner, when the terminal sends multiple ones of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the base station, one or two of the multiple ones satisfy the first sending condition.

[0224] For example, when the terminal sends the scatterer quality and the radio frequency channel quality to the base station, one or two of the multiple ones satisfying the first sending condition can be that one of the multiple ones satisfies the first sending condition. For example, if the scatterer quality meets the first requirement, reference can be made to Figure 5Implement according to the illustrated embodiment. Only when the scatterer quality meets the first requirement will the terminal and the base station perform radio frequency channel quality assessment, and only then will the terminal send the radio frequency channel quality to the base station. When the scatterer quality does not meet the first requirement, the terminal and the base station will not perform radio frequency channel quality assessment. The base station will re-obtain the environmental reconstruction result and re-perform scatterer quality assessment with the terminal until the scatterer quality meets the first requirement. Only then will the terminal and the base station perform radio frequency channel quality assessment, and only then will the terminal send the radio frequency channel quality to the base station. That is to say, when the scatterer quality does not meet the first requirement, the terminal will adjust the scatterer quality to meet the first requirement and then send the radio frequency channel quality to the base station. Reference can be made to Figure 5 the illustrated embodiment.

[0225] For another example, when the terminal sends the scatterer quality and the radio frequency channel data application quality to the base station, that one or two of the multiple items meet the first sending condition can be that one of the multiple items meets the first sending condition. For example, the scatterer quality meets the first requirement. Reference can be made to Figure 5 the illustrated embodiment. When the scatterer quality meets the first requirement, the terminal and the base station will perform radio frequency channel mapping data application quality assessment, and the terminal will send the radio frequency channel mapping data application quality to the base station. When the scatterer quality does not meet the first requirement, the terminal and the base station will not perform radio frequency channel mapping data application quality assessment. The base station will re-obtain the environmental reconstruction result and re-perform scatterer quality assessment with the terminal until the scatterer quality meets the first requirement. The terminal and the base station will perform radio frequency channel mapping data application quality assessment, and the terminal can send the radio frequency channel mapping data application quality to the base station. That is to say, when the scatterer quality does not meet the first requirement, the terminal will adjust the scatterer quality to meet the first requirement and then send the radio frequency channel mapping data application quality to the base station. Reference can be made to Figure 5 the illustrated embodiment.

[0226] For another example, when the terminal sends the radio frequency channel quality and the radio frequency channel data application quality to the base station, that one or two of the multiple items meet the first sending condition can be that one of the multiple items meets the first sending condition. For example, the radio frequency channel quality meets the second requirement. Reference can be made to Figure 6Implement according to the illustrated embodiment. When the radio frequency channel quality meets the second requirement, the terminal and the base station will perform an evaluation on the quality of radio frequency channel mapping data application, and the terminal will send the quality of radio frequency channel mapping data application to the base station. When the scatterer quality does not meet the second requirement, the terminal and the base station will not perform an evaluation on the quality of radio frequency channel mapping data application. The base station will re-obtain the radio frequency channel mapping data and re-perform a radio frequency channel quality evaluation with the terminal until the radio frequency channel quality meets the second requirement. Then, the terminal and the base station will perform an evaluation on the quality of radio frequency channel mapping data application, and the terminal can send the quality of radio frequency channel mapping data application to the base station. That is to say, when the radio frequency channel quality does not meet the second requirement, the terminal will adjust the radio frequency channel quality to meet the second requirement and then send the quality of radio frequency channel mapping data application to the base station. Reference can be made to Figure 6 Implement according to the illustrated embodiment.

[0227] For another example, when the terminal sends the scatterer quality, radio frequency channel quality, and radio frequency channel application quality to the base station, that one or two of the multiple items meet the first sending condition can mean that two of the multiple items meet the first sending condition. For example, the scatterer quality meets the first requirement and the radio frequency channel direct connection further meets the second requirement. Reference can be made to Figure 5 and Figure 6 Implement according to the illustrated embodiment. When the scatterer quality meets the first requirement and the radio frequency channel quality meets the second requirement, the terminal and the base station will perform an evaluation on the quality of radio frequency channel mapping data application, and the terminal will send the quality of radio frequency channel mapping data application to the base station. When the scatterer quality does not meet the first requirement, the terminal will adjust the scatterer quality to meet the first requirement and then send the radio frequency channel quality to the base station. Reference can be made to Figure 5 Implement according to the illustrated embodiment. Similarly, when the scatterer quality does not meet the second requirement, the terminal will adjust the radio frequency channel quality to meet the second requirement and then send the quality of radio frequency channel mapping data application to the base station. Reference can be made to Figure 6 Implement according to the illustrated embodiment.

[0228] In the embodiment of the present application, if the quality of radio frequency channel mapping data application does not meet the third requirement, it can be considered that the compression method of the radio frequency channel mapping data is incorrect, or the parameters selected when generating the radio frequency channel mapping data are inaccurate. Then, the performance of the terminal for performing perception-assisted communication based on this radio frequency channel mapping data is low. Therefore, the base station can adjust the compression method of the radio frequency channel mapping data or the parameters selected when generating the radio frequency channel mapping data in order to improve the performance of perception-assisted communication.

[0229] When the application quality of the radio frequency channel mapping data meets the third requirement, the terminal can adopt the radio frequency channel mapping data, such as the first radio frequency channel mapping data, for perception-assisted communication. If the application quality of the radio frequency channel mapping data does not meet the third requirement, it can be considered that the accuracy of the radio frequency channel mapping data is low. This problem may be caused by the fact that in order to reduce the transmission pressure, the base station compresses the radio frequency channel mapping data and sends it to the terminal, and then the terminal expands it, or it may also be caused by the parameters selected by the base station when generating the radio frequency channel mapping data, such as inaccurate communication links. Therefore, when the base station determines that the application quality of the radio frequency channel mapping data does not meet the third requirement, the base station can adjust the compression method of the radio frequency channel mapping data or the parameters selected when generating the radio frequency channel mapping data, and send the adjusted radio frequency channel mapping data, such as the second radio frequency channel mapping data, to the terminal. The terminal can perform perception-assisted communication based on the adjusted radio frequency channel mapping data.

[0230] In a possible scenario, the processing operation of the base station can be performed by the CU, and the transceiver operation of the base station can be performed by the DU or RU. For example, the CU can generate a quality measurement request, and the CU can send the quality measurement request to the DU. The DU can send the quality measurement request, or the DU can send the quality measurement request to the RU, and the RU can send it.

[0231] The DU can receive one or more of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality, and send one or more of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the CU. It is determined by the CU whether it is necessary to re-obtain the environmental reconstruction result, whether it is necessary to re-generate the radio frequency channel mapping data, or whether it is necessary to re-select the parameters included in the radio frequency channel mapping data and / or the compression method of the radio frequency channel mapping data. Optionally, the RU can receive one or more of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality, and send one or more of the scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the DU.

[0232] In another possible scenario, the processing operation of the base station can be performed by the CU-CP, and the transceiver operation of the base station can be performed by the DU or RU. For example, the CU-CP can perform the above operations of the CU, the DU can perform the above operations of the DU, and the RU can perform the above operations of the RU.

[0233] In the O-RAN scenario, the operations performed by the above CU can be performed by the O-CU, the operations performed by the DU can be performed by the O-DU, the operations performed by the RU can be performed by the O-RU, and the operations performed by the CU-CP can be performed by the O-CU-CP.

[0234] by Figure 9As can be seen from the embodiments shown, in the radio frequency data evaluation method provided by the embodiments of the present application, a multi-layer evaluation method is adopted, such as scatterer quality evaluation, radio frequency channel quality evaluation, and radio frequency channel mapping data application quality evaluation, which can improve the reliability and service performance of radio frequency channel mapping data. Below, in combination with Figure 9 This paper introduces the radio frequency data evaluation method provided by the embodiments of the present application.

[0235] Such as Figure 10 As shown, sensing communication nodes, such as base stations, terminals, TRPs, etc., can obtain environmental information through sensing and determine the environmental reconstruction result, which can be implemented with reference to Figures 4A to 4B the embodiments shown. The base station and the terminal can perform scatterer quality evaluation, which can be implemented with reference to Figure 5 the embodiments shown. When the scatterer quality meets the first requirement, the terminal and the base station can generate radio frequency channel mapping data, which can be implemented with reference to Figures 4C to 4D the embodiments shown.

[0236] In a possible case, after generating the radio frequency channel mapping data, the terminal and the base station can perform radio frequency channel quality evaluation, which can be implemented with reference to Figure 6 the embodiments shown. If the radio frequency channel quality does not meet the second requirement, the base station can return to perform the operation of generating radio frequency channel mapping data. If the radio frequency channel quality meets the second requirement, the base station can determine the parameters included in the radio frequency channel mapping data and / or determine the radio frequency channel mapping data compression method, and the base station sends the radio frequency channel mapping data to the terminal. It can be understood that the radio frequency channel mapping data can be sent after compression. The terminal can recover the compressed radio frequency channel mapping data and perform sensing-assisted communication based on the radio frequency channel mapping data. The terminal can determine the radio frequency channel mapping data application quality of the sensing-assisted communication of the radio frequency channel mapping data and send the radio frequency channel mapping data application quality to the base station. If the radio frequency channel mapping data application quality meets the third requirement, the terminal continues to use the radio frequency channel mapping data for sensing-assisted communication. If the radio frequency channel mapping data application quality does not meet the third requirement, the base station returns to perform the operation of determining the parameters when generating the radio frequency channel mapping data and / or determining the radio frequency channel mapping data compression method.

[0237] In another possible situation, after generating the RF channel mapping data, the base station may determine the parameters when generating the RF channel mapping data and / or determine the compression method of the RF channel mapping data, and the base station sends the RF channel mapping data to the terminal. It is understandable that the RF channel mapping data may be sent after compression. The terminal may perform perception-assisted communication based on the restored compressed RF channel mapping data and the RF channel mapping data. The terminal may determine the application quality of the RF channel mapping data for perception-assisted communication of the RF channel mapping data, and send the application quality of the RF channel mapping data to the base station. If the application quality of the RF channel mapping data meets the third requirement, the terminal continues to use the RF channel mapping data for perception-assisted communication. If the application quality of the RF channel mapping data does not meet the third requirement, the base station returns to the operation of determining the parameters when generating the RF channel mapping data and / or determining the compression method of the RF channel mapping data.

[0238] In one possible implementation, the RF channel mapping data can be managed by various functions and modules in an ISAC (integrated sensing and communication / joint communication and sensing) system. It is understood that the ISAC system can be set in a base station, a terminal, a TRP or a CPE. Figure 11 The ISAC wireless data acquisition module can acquire the sensing data of each sensing communication node and send the sensing data to the ISAC data processing module, which generates the sensing result, that is, generates the RF channel mapping data. The ISAC data processing module can send the RF channel mapping data to the sensing result and RF mapping data storage module for storage. The ISAC management module can send a sensing result transfer request to the sensing result and RF mapping data storage module to request to obtain the sensing result, that is, the RF channel mapping data. The sensing result and RF mapping data storage module can send the RF channel mapping data to the ISAC management module. The ISAC RF mapping application module can send a RF channel data application request to the ISAC management module, and the ISAC management module sends the RF channel mapping data to the ISAC RF mapping application module for sensing-assisted communication, such as energy saving, beamforming or beamforming, positioning or multiple-input multiple-output (MIMO) data transmission.

[0239] Among them, the ISAC wireless data acquisition module can also obtain quality data, such as scatterer quality or RF channel quality, and send the quality data to the ISAC management module, and the ISAC management module determines whether it is necessary to re-perceive. If the ISAC management module determines that re-perception is required, the ISAC management module can send a re-perception request to the ISAC data processing, and the ISAC data processing module can re-perceive or regenerate the RF channel mapping data. The ISAC management module can also send scatterer quality or RF channel quality to the ISAC data processing module. The ISAC wireless data acquisition module can also obtain application data, such as RF channel mapping data application quality, ACK, NACK or QOS. The ISAC wireless data acquisition module can send application data to the ISAC RF mapping application module, and the ISAC RF mapping application module can send application data to the ISAC management module. The ISAC management module determines whether it is necessary to reselect the parameters and / or compression method contained in the RF channel mapping data. The ISAC management module can also send the RF channel mapping data application quality to the ISAC data processing module.

[0240] Understandably, Figure 11 The names of the modules shown are only shown as examples and do not limit the names of the modules in the ISAC system.
