[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on January 9, 2024, with application number 202410035381.0 and application name "A Method and Device for Radio Frequency Data Evaluation", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of wireless communication technology, and in particular to a radio frequency data evaluation method and device. Background Art

[0004] Currently, using the environmental information obtained through perception to achieve higher spectrum efficiency or a more robust, resilient and easily recoverable network through perception-assisted communication has become a major topic in perception-assisted communication. Perception-assisted channel prediction and perception-assisted positioning are important topics in perception-assisted communication. The environmental information obtained through perception is used to predict the radio frequency channel conditions such as communication and positioning.

[0005] However, environmental information obtained through sensing may contain certain errors. This error may be caused by differences between the environmental information obtained through sensing and the actual environmental information or electromagnetic environment. It may also be caused by losses caused by compressing the environmental information obtained through sensing to reduce communication pressure and then expanding it. Therefore, the accuracy of environmental information obtained through sensing will affect the results of services such as sensing-assisted channel prediction and sensing-assisted positioning. Summary of the Invention

[0006] The present application provides a radio frequency data evaluation method and apparatus to improve the performance of perception-assisted communication.

[0007] In a first aspect, a method for evaluating radio frequency data is provided. The method can be executed by a first communication device, or by a chip / chip system. The first communication device can be a terminal device or a network device. The method is described by taking the first communication device as an example. In the 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 the scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality. The scatterer quality characterizes the accuracy of the position of the scatterer 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 the first radio frequency channel mapping data.

[0008] Based on the above scheme, the first communication device can obtain the RF channel mapping data by utilizing the environmental information obtained by perception, and determine one or more of the scatterer quality, RF channel quality and RF channel mapping data application quality based on the quality measurement request, so as to evaluate the accuracy of the RF channel mapping data, and evaluate whether the RF channel mapping data can be applied to perception-assisted communications such as perception-assisted channel prediction and perception-assisted positioning, so as to improve the performance of perception-assisted communications.

[0009] In one possible implementation, a first communications device transmits multiple items of scatterer quality, RF channel quality, and RF channel mapping data application quality. One or two of the multiple items among scatterer quality, RF channel quality, and RF channel mapping data application quality satisfy a first sending condition. For example, when the multiple items include scatterer quality and RF channel quality, satisfying the first sending condition may mean that one of the multiple items satisfies the first sending condition, such as scatterer quality satisfies a first requirement. For another example, when the multiple items include scatterer quality and RF channel mapping data application quality, satisfying the first sending condition may mean that one of the multiple items satisfies the first sending condition, such as scatterer quality satisfies the first requirement. For another example, when the multiple items include RF channel quality and RF channel mapping data application quality, satisfying the first sending condition may mean that one of the multiple items satisfies the first sending condition, such as RF channel quality satisfies a second requirement. For another example, when the multiple items include scatterer quality, RF channel quality, and RF channel mapping data application quality, satisfying the first sending condition may mean that both of the multiple items satisfy the first sending condition, such as scatterer quality satisfies the first requirement and RF channel quality satisfies the second requirement.

[0010] Based on the above scheme, the first communication device can send multiple items of scatterer quality, RF channel quality and RF channel mapping data application quality to the second communication device when one or two of the multiple items of scatterer quality, RF channel quality and RF channel mapping data application quality meet the first sending condition. It can be understood that when one or two of the multiple items of scatterer quality, RF channel quality and RF channel mapping data application quality do not meet the first sending condition, such as when the multiple items include scatterer quality and RF channel quality and the scatterer quality does not meet the first requirement, the RF channel quality may not be sent; when the multiple items include scatterer quality and RF channel mapping data application quality and the scatterer quality does not meet the first requirement, the RF channel mapping data application quality may not be sent; when the multiple items include RF channel quality and RF channel mapping data application quality and the RF channel quality does not meet the second requirement, the RF channel quality may not be sent, which can reduce system overhead.

[0011] In one possible implementation, the multiple items include scatterer quality and radio frequency channel quality, and satisfying the first sending condition includes that the scatterer quality satisfies a first requirement.

[0012] Based on the above solution, if the scatterer quality meets the first requirement, the estimated position of the scatterer can be considered to be highly accurate. Therefore, the accuracy of the RF channel mapping data generated based on the environment reconstruction result including the scatterer is also relatively high. Therefore, the RF channel quality can be evaluated with the second communication device, and the RF channel quality can be sent to the second communication device. If the scatterer quality does not meet the first requirement, the first communication device and the second communication device will not perform the RF channel quality evaluation process, and the first communication device will not send the RF channel quality to the second communication device, thereby reducing system overhead.

[0013] In one possible implementation, the multiple items include scatterer quality and radio frequency channel mapping data application quality, and satisfying the first sending condition includes that the scatterer quality satisfies the first requirement.

[0014] Based on the above solution, when the quality 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 RF channel mapping data generated based on the environmental reconstruction result including the scatterer will also be relatively high. Therefore, the RF channel mapping data can be used for perception-assisted communication. The first communication device can evaluate the application quality of the RF channel mapping data with the second communication device, and thus can send the application quality of the RF channel mapping data to the second communication device. If the quality of the scatterer does not meet the first requirement, the first communication device and the second communication device will not evaluate the application quality of the RF channel mapping data. Therefore, 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.

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

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

[0017] In one possible implementation, the multiple items include scatterer quality, RF channel quality, and RF channel mapping data application quality, and satisfying the first sending condition includes that the scatterer quality satisfies the first requirement, and the RF channel quality satisfies the second requirement.

[0018] Based on the above scheme, when the scatterer quality 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 perception-assisted communication, and the first communication device can evaluate the application quality of the RF channel mapping data with the second communication device, so that the RF channel mapping data application quality can be sent to the second communication device. If the scatterer quality does not meet the first requirement, the first communication device and the second communication device will not evaluate the RF channel quality and the RF channel mapping data application quality, and the first communication device will not send the RF channel quality and the RF channel mapping data application quality to the second communication device, which can reduce the system overhead. If the scatterer quality 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 RF channel mapping data application quality to the second communication device, which can reduce the system overhead.

[0019] In a possible implementation, before the first communication device sends the radio frequency channel quality, if the scatterer quality does not meet the first requirement, the radio frequency channel quality is sent after the scatterer quality is adjusted to meet the first requirement.

[0020] Based on the above scheme, when the scatterer quality does not meet the first requirement, the first communication device may not send the RF channel quality, thereby reducing the system overhead, and send the RF channel quality after adjusting the scatterer quality to meet the first requirement to evaluate the accuracy of the generated RF channel mapping data.

[0021] In one possible implementation, before the first communication device sends the RF channel mapping data application quality, if the scatterer quality does not meet the first requirement, the scatterer quality is adjusted to meet the first requirement, and then the RF channel mapping data application quality is sent. Alternatively, before the first communication device sends the RF channel mapping data application quality, if the RF channel quality does not meet the second requirement, the RF channel quality is adjusted to meet the second requirement, and then the RF channel mapping data application quality is sent.

[0022] Based on the above scheme, when the scatterer quality does not meet the first requirement or the scatterer quality does not meet the second requirement, the first communication device may not send the RF channel mapping data application quality, thereby reducing the system overhead, and after adjusting the scatterer quality to meet the first requirement or adjusting the RF channel quality to meet the second requirement, the RF channel mapping data is used for perception-assisted communication to evaluate the application quality of the generated RF channel mapping data.

[0023] In one possible implementation, the application quality of the RF channel mapping data does not meet the third requirement, the first communication device receives second RF channel mapping data, the parameters contained in the second RF channel mapping data are different from the parameters contained in the first RF channel mapping data and / or the compression method of the second RF channel mapping data is different from the compression method of the first RF channel mapping data.

[0024] Based on this solution, if the application quality of the RF channel mapping data does not meet the third requirement, it can be considered that the accuracy of the RF channel mapping data is low. This problem may be caused by the second communication device compressing the RF channel mapping data and sending it to the first communication device in order to reduce transmission pressure, and the first communication device then expanding it. Or it may be caused by the parameters selected by the second communication device when generating the RF channel mapping data, such as an inaccurate communication link. Therefore, the second communication device can adjust the parameters selected when generating the RF channel mapping data and / or the compression method of the RF channel mapping data to improve the accuracy and / or reception performance of the RF channel mapping data.

[0025] In a second aspect, a method for evaluating radio frequency data is provided. The method can be executed by a second communication device, or by a chip / chip system. The second communication device can be a terminal device or a network device. The method is described by taking the second communication device as an example. 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 radio frequency channel mapping data application quality. The scatterer quality characterizes the accuracy of the position of the scatterer 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 the first radio frequency channel mapping data.

[0026] In one possible implementation, the second communication device receives multiple items of scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality, wherein the multiple items of scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality meet the first sending condition.

[0077] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are introduced below.

[0078] 1) Perception, also known as wireless sensing, involves emitting electromagnetic energy into space. By receiving radio waves reflected by objects in that space, information about the object can be calculated. For example, parameters such as position, direction, altitude, speed, size, and path of motion can be detected, as well as the internal and external shape and structure of the object. By exploring the transmission, echo, reflection, and scattering of radio waves, we can perceive and better understand the physical world. As one of the electromagnetic wave sensing technologies, wireless sensing technology, due to its penetrating and secure nature, can serve as an important alternative technology for security inspections, hidden object detection, and environmental reconstruction, as shown in Figure 1.

[0079] 2) Integrated communication and perception systems, also known as integrated synaesthesia systems, integrate electromagnetic signals used for communication and perception. Traditionally, active positioning targets primarily consisted of terminal devices that emit electromagnetic waves, such as mobile phones, vehicles, and Internet of Things (IoT) devices. However, virtual environment reconstruction targets further include passive objects, such as buildings, urban infrastructure (such as billboards and bridges), and traffic conditions (such as vehicles and bicycles). By receiving electromagnetic wave signals propagating through the spatial environment and determining its composition, the virtual environment (active and passive objects and devices) is detected and reconstructed to further enhance assisted positioning or perception-assisted communication performance. Network equipment and terminal devices are the primary devices involved in virtual environment reconstruction. The quality of perception is related to synaesthesia resources, space, time, frequency band, power consumption, and site. Sites can refer to network equipment, terminal devices, or customer premises equipment (CPE).

[0080] For example, spatial information includes the number of beams, which can affect the perceived angular range. Time includes the perceived symbol length, which can affect the perceived azimuth accuracy. Frequency includes the perceived bandwidth, which can affect the perceived range accuracy. Power consumption includes the perceived signal power, which can affect the perceived distance range. A station can include the communication capacity, which can affect the perceived fusion accuracy.

[0081] Based on whether the transmitting and receiving ends of the sensing signal are co-located or not, it can be divided into single-base (monostatic), dual-base (bi-static) and multi-base (multi-static). Multi-base is generally a hybrid system composed of single base and dual base, and two typical communication perception integrated system architectures are shown in Figures 2A and 2B. It can be understood that single-base perception can also be called single-station perception, that is, perception is performed through one site. Similarly, multi-base perception can also be called multi-station perception, that is, perception is performed through two or more sites. Similarly, multi-base perception can be called multi-station perception.

[0082] Figure 2A shows a single-base communication and perception integrated system. In the single-base communication and perception integrated system, the perception transmitter and the perception receiver are in the same location, and the perception signal can use data static load, so the perception function does not consume communication resources. At the same time, since the transmission and reception are from the same source, there are no non-ideal factors such as synchronization, and the complexity of its perception algorithm and estimation accuracy are better. Since the single-base environment reconstruction adopts self-transmission and self-reception, the signal angle range that can be detected is strongly related to the environmental incident angle. The reflected signal of the object decays rapidly as the incident angle increases. That is, the viewing angle range of the single-base environment reconstruction is greatly affected by the material and placement angle of the target object. Due to the use of single-base perception, most of the components of its echo signal are single bounces, which meets the radar assumption. When solving the environmental space, the problem of ill-conditioned equations is smaller, and the solution accuracy of the spatial environment is higher.

[0083] Figure 2B shows a dual-base sensing communication integrated system. In the dual-base sensing communication integrated system, the sensing receiver and the sensing transmitter are in different positions, and the sensing signal needs to use a dedicated pilot or a known signal, so the sensing function needs to consume communication resources. At the same time, due to the different sources of transmission and reception, there are non-ideal factors such as synchronization and phase noise. The complexity and estimation accuracy of its sensing algorithm are poor, and a more complex calibration algorithm is required to process it. In dual-base sensing, due to the use of spontaneous reception, the environmental angle it can detect is larger, and as the terminal moves, the sensing perspective has a larger coverage. In addition, its echo signal has rich components, a large number of multiple reflection paths (bounce is greater than or equal to 2) and high power. In urban spaces with rich scattering, a large number of multiple reflection paths will introduce ill-conditioned equations, resulting in shadow space and erroneous solutions when solving the virtual environment.

[0084] The technical solutions of the embodiments 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) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, and next-generation wireless communication systems such as 6G, without limitation.

[0085] FIG3 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in FIG3 , the communication system includes a wireless access network 100. The wireless access network 100 may include at least one network device (such as 110a and / or 110b in FIG3 ) and may also include at least one terminal device (such as at least one of 120a-120j in FIG3 ). 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. Terminal devices and network devices may be connected to each other by wire or by wireless. FIG3 is only a schematic diagram, and the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG3 .

[0086] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices, and is called a RAN device. For example, a network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. It can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU) or a distributed unit (DU). The CU here 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 the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The network device can be a macro base station (such as 110a in Figure 3), a micro base station or an indoor station (such as 110b in Figure 3), a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0087] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0088] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0089] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device may also be referred to as user equipment (UE), a mobile station, a mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home appliance, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0090] Network devices and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0091] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 3 can be configured as a mobile network device. For terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, for network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 3 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 3 can be referred to as communication devices with terminal device functionality.

[0092] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device function. The control subsystem that includes the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device function. In the following, the example in which the terminal device function is performed by the terminal and the network device function is performed by the base station is described.

[0093] Currently, leveraging environmental information acquired through sensing to achieve higher spectrum efficiency or more robust, resilient, and resilient networks through sensing-assisted communications has become a major focus in sensing-assisted communications. Key areas of sensing-assisted communications include sensing-assisted channel prediction and sensing-assisted positioning. Environmental information acquired through sensing is used to predict RF channel conditions for communication and positioning. This environmental information can be used to predict RF channel conditions, which can be referred to as RF channel maps, RF channel mapping data, or simply RF data.

[0094] However, RF channel mapping data may contain certain errors. These errors may be caused by differences between the environmental information obtained through perception and the actual environmental information or electromagnetic environment. They may also be caused by differences between the model used to generate RF channel mapping data based on the obtained environmental reconstruction results and the actual propagation mode. They may also be caused by losses caused by compressing RF channel mapping data before transmission and then expanding it to reduce communication pressure. Therefore, the accuracy of RF channel mapping data will affect the results of services such as perception-assisted channel prediction and perception-assisted positioning.

[0095] In view of this, an embodiment of the present application provides a radio frequency data evaluation method. In this method, a 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. The scatterer quality characterizes the accuracy of the position of the scatterer 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 the first radio frequency channel mapping data. Based on this scheme, 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 perception-assisted communications such as perception-assisted channel prediction and perception-assisted positioning, so as to improve the performance of perception-assisted communications.

[0096] In order to facilitate understanding of the technical solution provided in the embodiment of the present application, the method for obtaining radio frequency channel mapping data in the embodiment of the present application is introduced below.

[0097] In communication systems, wireless sensing technology is used to obtain environmental information to assist with channel prediction, positioning, beamforming, and other tasks, thereby improving communication service quality. The process of using wireless sensing technology to predict and generate a radio frequency channel mapping map is called radio frequency mapping (RF mapping). The map generated by RF mapping is called an RF channel map. The data corresponding to the RF channel map is called RF channel mapping data.

[0098] Referring to FIG4A , a physical environment map is shown. In FIG4A , the dotted line may represent a road. In an embodiment of the present application, radio frequency channel mapping data of the physical environment shown in FIG4A may be obtained. There may be multiple perception communication nodes in the physical environment, such as base stations, terminals, transmission and receiving points (TRPs) or CPEs, etc. The perception communication node may transmit electromagnetic waves or radar signals to obtain environmental reconstruction results, as shown in FIG4B . For example, the perception communication node may transmit electromagnetic waves or radar signals and receive echo signals, thereby obtaining scatterer information in the physical environment. In one possible scenario, each perception communication node may interact with the obtained scatterer information, thereby obtaining a higher-precision environmental reconstruction result within a larger range, as shown in FIG4B . Any of the above-mentioned multiple perception communication nodes may divide the physical environment map into multiple areas, and regard each area as a location. For ease of description, any of the above-mentioned perception communication nodes is referred to as a target perception communication node. For example, the target perception communication node may divide the physical environment map into multiple rectangular areas or grids, as shown in FIG4C . For another example, the target-aware communication node can divide the physical environment map into different circular areas (not shown in the figure). For another example, the target-aware communication node can divide the physical environment map into different hexagonal areas or so-called cellular areas (not shown in the figure), etc., which are not specifically limited in this application. It is understandable that when the target-aware communication node divides the physical environment map into multiple areas, the resolution of the area can be predefined or preconfigured by the protocol, such as dividing the physical environment map into multiple areas according to a resolution of 5m, 10m, etc., which is not specifically limited in this application.

[0099] This article takes the example of a target-aware communication node dividing the physical environment map into multiple grids.

[0100] The target-aware communication node can assume that there is a terminal in each location and simulate the transmission path from the base station to the terminal at each location, as shown in Figure 4C. It is understandable that the transmission path may include a direct transmission path from the base station to the terminal, or a transmission path that reaches the terminal after being reflected by a scatterer. For example, the target-aware communication node can use a mirror line-of-sight tracking algorithm to obtain the transmission path between the base station and the terminal at each location. The target-aware communication node can calculate the channel state prediction value of each location through the simulated transmission path, as shown in Figure 4D. Exemplarily, the target-aware communication node can calculate the channel state prediction value of the transmission path from the base station through the environment to the terminal at each location through a ray tracing tool, an electromagnetic calculation tool, or a simple simulation tool based on mirror reflection. In addition, the target-aware communication node can obtain the scatterer information associated with each location, that is, the information about the scatterer passed from the base station to the terminal at each location. In this way, the radio frequency channel mapping data can be obtained.

[0101] It should be noted that the above-mentioned method of obtaining radio frequency channel mapping data is only shown as an example and does not constitute a limitation on the method of obtaining radio frequency channel mapping data.

[0102] In one possible scenario, the RF channel mapping data involved in the embodiments of the present application may include the aforementioned location information of each location, the channel state prediction value of each location, and the scatterer information associated with each location. The location information may be indicated by a relative location, such as a distance or angle relative to a base station, or an absolute location, such as latitude and longitude information. Alternatively, the location information may be indicated by a grid number.

[0103] Optionally, if the location information is indicated by a grid number, the RF channel mapping data may also include grid setting information, which may indicate the grid's starting position and / or grid resolution. The grid's starting position may indicate the starting position when the grid is divided, and may be indicated by a relative position or an absolute position. The grid's resolution may indicate the scale used when dividing the grid. It is understood that the grid's resolution may not be indicated, and a default resolution may be used.

[0104] The multiple perception communication nodes existing in the above-mentioned physical environment may include a base station. In one possible scenario, the processing operation of the base station may be performed by the CU, and the transceiver operation of the base station may be performed by the DU or the RU. For example, the CU may generate electromagnetic waves for perception, 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, which may send them. Similarly, the DU may receive the electromagnetic waves and send them to the CU. The CU determines the scatterer information or the scatterer group information, thereby determining the environment reconstruction result. Optionally, the RU may receive the electromagnetic waves and send them to the DU.

[0105] In another possible scenario, the base station's processing operations can be performed by the CU-CP, and the base station's transceiver operations can be performed by the DU or RU. For example, the CU-CP can generate electromagnetic waves for sensing, and the CU-CP can send the electromagnetic waves to the DU. The DU can send the electromagnetic waves, or the DU can send the electromagnetic waves to the RU, which then sends them. Similarly, the DU can receive the electromagnetic waves and send them to the CU-CP. The CU-CP determines the scatterer information or scatterer group information, thereby determining the environment reconstruction result. Optionally, the RU can receive the electromagnetic waves and send them to the DU.

[0106] Similarly, the above-mentioned target perception communication node may be a base station, a terminal or a TRP. If the target perception communication node is a base station, in a possible scenario, the processing operation of the base station may be performed by the CU, and the sending and receiving operations of the base station may be performed by the DU or RU. For example, the CU may divide the physical environment map into multiple areas, each area as a location, and determine the RF channel mapping data for each location. The CU may send the RF channel mapping data to the DU, and the DU may send the RF channel mapping data to the terminal or the core network. Optionally, the DU may send the RF channel mapping data to the RU, and the RU may send the RF channel mapping data to the terminal or the core network.

[0107] In another possible scenario, the base station processing operations can be performed by the CU-CP, and the base station transceiver operations can be performed by the DU or RU. For example, the CU-CP can divide the physical environment map into multiple areas, each area as a location, and determine the RF channel mapping data for each location. The CU-CP can send the RF channel mapping data to the DU, and the DU can send the RF channel mapping data to the terminal or the core network. Optionally, the DU can send the RF channel mapping data to the RU, and the RU can send the RF channel mapping data to the terminal or the core network.

[0108] 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.

[0109] In this application, the radio frequency channel map can indicate the following two aspects of information:

[0110] On the one hand, the radio frequency channel map corresponds to a certain geographical area and is used to indicate the geographical locations and sizes of multiple areas divided within the geographical area.

[0111] The geographic area can be a certain range in the real physical world. For example, the geographic area can be represented by longitude, latitude, and altitude. For example, the starting point is recorded as (x_0, y_0, z_0), and a 100m×100m outdoor scene is based on this starting point.

[0112] The multiple regions may be regions obtained by dividing the geographical area in a certain manner. For example, the aforementioned 100m×100m geographical area may be divided into 1m×1m regions to obtain 100×100 regions, each of which is 1m×1m.

[0113] It is easy to understand that in this application, the area involved in the radio frequency channel map (that is, the area obtained by dividing the above-mentioned geographical area in a certain way) can have at least one of the following attributes: shape, size, area, geographical location, etc.

[0114] In this application, different regions have the same shape, outline, size, radius, and area. Different regions have different geographical locations. There is no overlap between different regions.

[0115] In a possible embodiment, the shape of the region may be a square, or other shapes, such as a rectangle, a trapezoid, a triangle, etc. Alternatively, the shape of the region may be an irregular shape, which is not limited.

[0116] For example, the shape of a region can be defined by a protocol or by a 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 ​​a region can be defined by a protocol or by a network device. The size, radius, and area of ​​a region 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.

[0117] In a possible implementation, multiple regions may be indexed (eg, numbered) to identify different regions.

[0118] In one possible scenario, the RF channel map includes multiple grids, and the multiple grids correspond one-to-one to multiple areas. It is easy to understand that in this application, the grids involved in the RF 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 area corresponding to the grid. The size of the grid is in a certain ratio to the size of the area corresponding to the grid. The area of ​​the grid is in a certain ratio to the area size of the area corresponding to the grid. Among them, the size of the grid can also be described in other ways, such as resolution.

[0119] In one possible implementation, if the relevant result of the environmental reconstruction result obtained by the sensing communication node is inaccurate, for example, if the position accuracy of the scatterer or scatterer group is low, the accuracy of the radio frequency channel mapping data obtained based on the environmental reconstruction result will also be relatively low. Therefore, in an embodiment of the present application, the quality of the scatterer can be evaluated. It is understandable that the quality of the scatterer can characterize the accuracy of the position of the scatterer or scatterer group. In the following, for the sake of convenience of description, the scatterer group and the scatterer are collectively referred to as scatterers. It is understandable that the scatterer in the following text can also be replaced by the scatterer group.

[0120] Referring to Figure 5, an exemplary flowchart of a scatterer quality assessment method is shown, which may include the following operations. In this method, a first communication device in the aforementioned perception communication node may initiate a scatterer quality assessment to a second communication device in the perception communication node. Figure 5 illustrates this using an example where the first communication device is a base station and the second communication device is a terminal.

[0121] S501: The base station sends a quality measurement request to the terminal.

[0122] Correspondingly, the terminal receives a quality measurement request from the base station.

[0123] For example, the base station may send a scatterer quality measurement request to the terminal. In the embodiment shown in Figure 5 , the base station may obtain the environment reconstruction result based on the method described in Figures 4A and 4B .

[0124] In one possible scenario, the environment reconstruction result or RF channel mapping data may be stored in a session management function (SMF) or a location management function (LMF) in a base station or a core network device. If the environment reconstruction result or RF channel mapping data is stored in the LMF or SMF, the SMF or LMF may initiate scatterer quality assessment. For example, the SMF or LMF may send a quality measurement request, such as a scatterer quality measurement request, to the base station, and the base station may execute S501.

[0125] It should be noted that the session management function network element and the positioning management function network element in the embodiments of the present application may be network elements having session management functions and positioning management functions, respectively. For ease of explanation, the session management function network element and the positioning management function network element are referred to as SMF and LMF, respectively, in the subsequent description of this application. It should be noted that in future communications, the session management function network element and the positioning management function network element may still be referred to as SMF and LMF, or may have other names, which are not limited by this application.

[0126] In one possible implementation, the base station may determine the terminal associated with the scatterer and send a quality measurement request to the associated terminal. For example, assuming that the base station wants to evaluate the scatterers {P1, P2, ..., P n The quality of {Q s1, Q s2, …,Q sn}, the base station may determine the terminal at the first position and send a quality measurement request to the terminal at the first position.

[0127] Optionally, the quality measurement request may include scatterer information, such as identification information of the scatterer and / or an estimated position of the scatterer, etc. It is understandable that the estimated position of the scatterer can be understood as the position of the scatterer obtained by the sensing communication node based on the echo signal in Figure 4A.

[0128] S502: The terminal sends the scatterer mass to the base station.

[0129] Correspondingly, the base station receives the scatterer mass from the terminal.

[0130] In one possible scenario, the terminal may obtain the true value of the position of the scatterer. For example, based on a map of the real physical environment, the terminal may obtain information on the position of the scatterer in the map, and regard it as the true value of the position of the scatterer, that is, the actual position. The terminal may determine the quality of the scatterer based on the true value of the position of the scatterer and the estimated position of the scatterer. For example, the terminal may calculate the difference, variance, or square difference between the true value of the position of the scatterer and the estimated position of the scatterer. The terminal may regard the obtained difference, variance, or square difference as the quality of the scatterer, or the terminal may determine the quality of the scatterer corresponding to the difference, variance, or square difference, that is, the terminal may quantify the quality of the scatterer based on the difference, variance, or square difference.

[0131] In another possible scenario, the terminal can obtain the location of an anchor point. For example, the terminal may store the location of a particular anchor point, such as a building, streetlight, or street. The building, streetlight, or street can be considered an anchor point. The terminal can estimate the location of the scatterer based on the location of the anchor point. The terminal can determine the scatterer quality based on the scatterer position estimated from the anchor point position and the estimated scatterer position. For details, refer to the previous description and will not be repeated here.

[0132] In another possible scenario, the terminal may obtain the position of the scatterer obtained through long-term cumulative measurements. For example, the terminal may obtain the position of the scatterer measured over a period of time, such as a year, a month, or a week. The terminal may calculate the average of these measurements. Based on this average and the estimated position of the scatterer, the terminal may determine the quality of the scatterer. Please refer to the previous description for details and will not be repeated here.

[0133] Optionally, in S502, the terminal may send the true value of the position of the scatterer obtained above, the position of the anchor point, or the average value of the position of the scatterer obtained by long-term accumulated measurement to the base station. The base station, LMF, or SMF may determine the quality of the scatterer based on the true value of the position of the scatterer from the terminal, the position of the anchor point, or the position of the scatterer obtained by long-term accumulated measurement, and the estimated position of the scatterer.

[0134] It should be noted that, through S501 and S502, it is possible to obtain the masses of multiple scatterers, such as the masses of the scatterers {P1, P2, ..., P n The quality of {Q s1, Q s2, …,Q sn The base station can be based on scatterers {P1, P2, ..., P n The quality of {Q s1, Q s2, …,Q sn}Determine the scatterer quality at the first location. For example, the base station may determine {Q s1, Q s2, …,Q sn The average value of} is used as the scatterer mass at the first position. s The following formula (1) can be satisfied.

[0135] Where n represents the number of scatterers associated with the first position, Q si Represents the mass of the i-th scatterer among n scatterers.

[0136] In one possible implementation, if the scatterer quality at the first position does not meet the first requirement, it can be considered that the scatterer quality at the first position is poor or the estimated scatterer position is inaccurate, and the base station can re-initiate the process of obtaining the environment reconstruction result. For example, the base station can schedule sensing resources based on the scatterer quality obtained this time, and the sensing communication node shown in Figure 4A can transmit electromagnetic waves or radar signals based on the scheduled sensing resources and receive echo signals to obtain the environment reconstruction result. The base station can also continue to execute S501 and S502 until the scatterer quality meets the first requirement.

[0137] It is 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, and this application does not impose any specific limitations. Where 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.

[0138] In one possible scenario, if the scatterer quality is determined based on the aforementioned difference, variance, or squared difference, then the scatterer quality threshold may be 1, 1.5, or 10%. In another possible scenario, if the scatterer quality is the difference, variance, or squared difference itself, then, for example, if the scatterer quality is the variance, the scatterer quality threshold may be 0.1, 0.01, or 0.5, etc., which is not specifically limited in this application.

[0139] Based on the above scheme, as shown in Figures 4A to 4D, the RF 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 scatterer position included in the environmental reconstruction result is relatively accurate. Therefore, the RF channel mapping data obtained based on the environmental reconstruction result will also be relatively accurate, which can improve the accuracy of the RF channel mapping data, thereby improving the performance of perception-assisted communication based on the RF channel mapping data. If the scatterer quality does not meet the first requirement, it can be considered that the scatterer quality does not meet expectations, and the RF channel mapping data obtained based on the environmental reconstruction result will also be inaccurate. Therefore, RF mapping can be performed without performing RF channel quality evaluation, and there is no need to send RF channel quality, so as to reduce system overhead.

[0140] Optionally, when the base station re-initiates acquisition of the environment reconstruction result, the base station can adjust the perception resources to improve the accuracy of the environment reconstruction result, such as the base station can adjust the transmission reception point (TRP), the number of antenna streams, the time domain resources used for perception, the frequency domain resource bandwidth and one or more of the space.

[0141] In an embodiment of the present application, if the scatterer quality at the first position meets the first requirement, it means that the scatterer quality meets expectations, and then the base station can initiate an evaluation of the RF channel quality or an evaluation of the application quality of the RF channel mapping data. It can be understood that the RF channel quality can characterize the deviation between the channel state measurement value and the channel state prediction value included in the RF channel mapping data, and the application quality of the RF channel mapping data characterizes the quality of use of the RF channel mapping data. Below, the methods of evaluating the RF channel quality and evaluating the application quality of the RF channel mapping data are introduced respectively through Figures 6 and 7.

[0142] Referring to Figure 6, an exemplary flow chart of a radio frequency channel quality assessment method provided in an embodiment of the present application may include the following operations. In this method, a first communication device in the aforementioned perception communication node may initiate a radio frequency channel quality assessment on a second communication device in the perception communication node. Figure 6 illustrates this using an example where the first communication device is a base station and the second communication device is a terminal.

[0143] S601: The base station sends a quality measurement request to the terminal.

[0144] Correspondingly, the terminal receives a quality measurement request from the base station. For example, the base station may send a radio frequency channel quality measurement request to the terminal.

[0145] Optionally, the quality measurement request in S601 may include RF channel mapping data, such as the RF channel mapping data obtained through the process shown in Figures 4A to 4D. Alternatively, the RF channel mapping data may have been previously sent to the terminal and stored in the terminal. In S601, the RF channel mapping data may be stored in the LMF or SMF in the base station or the core network device, and the base station may obtain the RF channel mapping data and send it to the terminal.

[0146] In one possible scenario, the base station may send relevant data for K locations to the terminal, such as location information for the K locations, channel state prediction values ​​for the K locations, and scatterer information associated with the K locations. The K locations include the first location where the terminal is located. 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 of the terminal and send relevant data for the K locations to the terminal. Optionally, the RF channel mapping data sent by the base station to the terminal may also include grid setting information.

[0147] In one example, the RF channel mapping data involved in the embodiments of the present application may further include a reference RF channel quality. It is understood that the reference perceived quality may be an initial value, that is, a reference RF channel quality determined based on a channel state estimate, or the reference RF channel quality may be an RF channel quality that has been updated through the embodiment shown in FIG6 . The RF channel mapping data sent by the base station to the terminal may further include the reference RF channel qualities of the aforementioned K positions.

[0148] Optionally, in order to perform RF channel quality assessment, the RF channel mapping data sent by the base station to the terminal may also include configuration information of the measurement signal for performing RF channel quality assessment, which may include one or more of the transceiver signal antenna port number (port), precoding information, and subcarrier configuration. It is understandable that the configuration information of the above-mentioned measurement signal may be the configuration information used by the sensing communication node to send electromagnetic waves when obtaining the environment reconstruction results shown in Figures 4A to 4B, such as the transceiver antenna port number, precoding information, and subcarrier configuration. This is to reduce the error caused by the difference in precoding information, subcarrier configuration, and transceiver antenna port number, so as to improve the accuracy of the RF channel quality.

[0149] In a possible implementation, S601 may be executed after the scatterer quality meets the first requirement. If the RF 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.

[0150] S602: The base station sends a measurement signal to the terminal.

[0151] Correspondingly, the terminal receives the measurement signal from the base station.

[0152] 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).

[0153] In one possible implementation, the terminal may obtain configuration information for the measurement signal. For example, the terminal may receive the configuration information for the measurement signal from a 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. The system message may include the configuration information for the measurement signal.

[0154] It should be noted that when a base station sends a measurement signal, it may send it according to the configuration information of the measurement signal. For example, the measurement signal may be sent using the transmit and receive antenna port number, precoding information, and subcarrier configuration indicated in the configuration information of the measurement signal. Similarly, when a terminal receives a measurement signal, it may receive it according to the configuration information of the measurement signal. For example, the measurement signal may be received using the transmit and receive antenna port number, precoding information, and subcarrier configuration indicated in the configuration information of the measurement signal.

[0155] The terminal can measure the measurement signal to obtain a channel state measurement value. For example, the terminal can 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), etc. of the measurement signal, which is not specifically limited in this application. The terminal can determine the RF channel quality of the first position based on the channel state measurement value and the channel state prediction value of the first position. For example, the terminal determines the RF channel quality by determining the correlation between the channel state measurement value and the channel state prediction value, which is introduced below.

[0156] For example, the channel state prediction value of the first position included in the radio frequency channel mapping data is R iElement composition, indicated in the first position (x i ,y i, z i ) is the multipath component predicted by the environment, which is expressed by formula (2): 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 determine the measurement result, which is expressed by formula (3):

[0158] The first location of the terminal can be determined by (x ue ,y ue, z ue ) represents. Optionally, when the positioning capability 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 line of sight (LOS) condition is well evaluated, so (x ue ,y ue, z ue ) and the corresponding R ue It can be put into the record stack to represent the real-world truth information.

[0159] It should be noted that the terminal can determine R using algorithms such as Euclidean distance, Manhattan distance, cosine similarity, Pearson correlation, and Jaccard similarity. i and R ue The correlation between the two is shown in Figure 2. This is explained using the Euclidean distance as an example.

[0160] The terminal can determine R i and R ue Correlation S i =f(R i ,R ue ), as the RF channel quality, is expressed by formula (4):

[0161] Among them, Q R Can be used as the RF channel quality.

[0162] S603: The terminal sends the radio frequency channel quality to the base station.

[0163] Correspondingly, the base station receives radio frequency channel quality from the terminal.

[0164] In one possible scenario, in S603, the terminal may send a channel state measurement value to the base station. The base station, LMF, or SMF may determine the RF channel quality based on the channel state measurement value and the channel state prediction value. The methods described in formulas (2) to (4) may be referred to, and the repetitions are not repeated here.

[0165] In one possible implementation, if the RF channel quality does not meet the second requirement, such as when the RF channel quality is greater than or equal to the RF channel quality threshold, indicating that the channel state prediction value does not meet expectations, that is, the channel state prediction value is inaccurate, the base station may regenerate the RF channel mapping data and re-initiate the RF channel quality assessment process until the RF channel quality meets the second requirement. Optionally, if the RF channel quality does not meet the second requirement, the base station may adjust the RF mapping data generation parameters when regenerating the RF channel mapping data to improve the accuracy of the RF channel mapping data.

[0166] It is understandable that the radio frequency channel quality threshold may be set based on an empirical value, such as 10 dBM, etc., and this application does not impose any specific limitation.

[0167] In an embodiment of the present application, if the RF channel quality meets the second requirement, such as if the RF channel quality is less than or equal to the RF channel quality threshold, it indicates that the RF channel quality meets expectations, and the base station may update the reference RF channel quality of other locations associated with the scatterer associated with the first position, such as locations other than the first position, to the aforementioned RF channel quality that meets the second requirement. Hereinafter, the other locations associated with the scatterer associated with the first position are referred to as second positions.

[0168] Refer to Figure 7, which shows a schematic diagram of updating perceived quality. As shown in Figure 7, the terminal can be in a first position (the shaded rectangle shown in Figure 7a). Through the embodiment shown in Figure 6, the RF channel quality of the first position can be determined. The terminal or base station can determine the second position associated with the scatterer associated with the first position through the RF channel mapping data (the black rectangle shown in Figure 7b). The terminal or base station can also update the reference RF channel quality of the second position to the RF channel quality. In other words, the positions of the scatterers associated with the first position can uniformly update the RF channel quality.

[0169] In one possible scenario, assuming that the scatterers associated with the first position include scatterers A and B, and the scatterers associated with the second position, such as position X, include scatterers A, B, and C, then the first communication device and the second communication device can use scatterers A, B, and C to predict the channel state value R. iThe contribution of each scatterer is used to determine the weight of each scatterer. Then the RF channel quality Q at position X is R = mass of scatterer A (RF channel quality) * weight of scatterer A + mass of scatterer B (RF channel quality) * weight of scatterer B + weight of scatterer C * mass of scatterer C. The mass of scatterer C can be represented by the embodiment shown in FIG6 , except that, when determining the mass of scatterer C, the communication device located at a position associated with scatterer C needs to execute the embodiment shown in FIG6 .

[0170] Based on the above scheme, if the RF channel quality meets the second requirement, it can be considered that the RF channel quality meets expectations, and the RF channel quality can feedback the quality of the communication link between the terminal and the base station. Therefore, if the RF 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 expectations. As shown in Figures 4A to 4D, the communication link between the terminal and the base station can include a direct link or a transmission path after reflection from a scatterer. Therefore, if the RF channel quality meets expectations, it means that the position of the scatterer is relatively accurate. Therefore, the RF channel quality of the second position associated with the scatterer can be updated based on the RF channel quality, so that the RF channel mapping data can be used for perception-assisted communication, which can improve the service performance of the RF channel mapping data.

[0171] In one possible implementation, if the RF channel quality meets the second requirement, it means that the RF channel quality meets expectations, that is, the RF channel quality of the first position and the aforementioned second position is relatively accurate, then the relevant data of the first position and the aforementioned second position, such as the channel state prediction value of the first position and the aforementioned second position, the scatterer information associated with the first position and the aforementioned second position, or one or more of the RF channel qualities of the first position and the aforementioned second position can be used for perception-assisted communication, and the protocol can enable perception-assisted communication of the relevant data about the first position in the RF channel mapping data. For example, the base station can send updated RF channel mapping data to the terminal, such as the RF channel mapping data after updating the reference RF channel quality to the RF channel quality in S602, and the terminal can use the relevant data about the first position and the aforementioned second position in the updated RF channel mapping data for perception-assisted communication.

[0172] In another possible implementation, if the scatterer quality meets the first requirement, it means that the scatterer quality meets expectations, that is, the position of the scatterer associated with the first position included in the environment reconstruction result is relatively accurate, so the relevant data about the first position in the RF channel mapping data generated based on the environment reconstruction result is relatively accurate. Then the relevant data of the first position and the aforementioned second position, such as the channel state prediction value of the first position and the aforementioned second position, the scatterer information associated with the first position and the aforementioned second position, or one or more of the RF channel qualities of the first position and the aforementioned second position can be used for perception-assisted communication, and the protocol can enable perception-assisted communication of the relevant data about the first position in the RF channel mapping data. For example, the base station can send updated RF channel mapping data to the terminal, such as the RF channel mapping data after updating the reference RF channel quality to the RF channel quality in S603, and the terminal can use the relevant data about the first position and the aforementioned second position in the updated RF channel mapping data for perception-assisted communication.

[0173] In another possible implementation, if the scatterer quality meets the first requirement and the RF channel quality meets the second requirement, then the relevant data of the first position and the aforementioned second position, such as the channel state prediction value of the first position and the aforementioned second position, the scatterer information associated with the first position and the aforementioned second position, or one or more of the RF channel qualities of the first position and the aforementioned second position can be used for perception-assisted communication, and the protocol can enable perception-assisted communication of the relevant data of the first position and the aforementioned second position in the RF channel mapping data. For example, the base station can send updated RF channel mapping data to the terminal, such as the RF channel mapping data after updating the reference RF channel quality to the RF channel quality in S603, and the terminal can use the relevant data of the first position and the aforementioned second position in the updated RF channel mapping data for perception-assisted communication.

[0174] In one possible scenario, the RF channel mapping data that the base station may send to the terminal may include relevant data of M positions, where the M positions may include a first position and the aforementioned second position, and M is an integer greater than or equal to 1. For example, the RF channel mapping data sent by the base station to the terminal may include position information of M positions, channel state prediction values ​​of the M positions, and scatterer information or scatterer group information associated with the M positions. Optionally, the RF 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 K positions mentioned above.

[0175] In one example, the RF channel mapping data sent by the base station to the terminal may also include the RF channel quality as shown in Figure 6. Optionally, the RF channel mapping data sent by the base station to the terminal may also include RF channel mapping data application quality, which may be determined based on the embodiment shown in Figure 8.

[0176] Optionally, the RF channel mapping data sent by the base station to the terminal may also include configuration information of the measurement signal for performing RF channel quality assessment, which may include one or more of the transmit and receive signal antenna port number (port), precoding information, and subcarrier configuration.

[0177] Exemplarily, in an embodiment of the present application, the radio frequency channel mapping data sent by the base station to the terminal may include the content shown in the following Table 1.

[0178] Table 1: Example of RF channel mapping data

[0179] As shown in Table 1, the RF channel mapping data sent by the base station to the terminal may include one or more of the following: measurement signal configuration information, grid setting information, location information, channel state prediction value, associated scatterer or scatterer group, and associated perceived quality. Each of these is described below.

[0180] 1. The configuration information of the measurement signal may include one or more of the antenna port number for transmitting and receiving signals, precoding information, and subcarrier configuration.

[0181] It is understandable that the configuration information of the above-mentioned measurement signal may be the configuration information used by the perception communication node to send electromagnetic waves when obtaining the environment reconstruction result, such as the transceiver antenna port number, precoding information and subcarrier configuration.

[0182] 2. Location information, indicating geographic location. Location information can be relative, such as distance or angle relative to a base station, or absolute, such as latitude and longitude. Alternatively, location information can be indicated by a grid number. In Table 1, the subscript i can be understood as the grid number.

[0183] 3. Grid setting information, indicating the starting position of the grid and / or the resolution of the grid.

[0184] The grid start position may indicate the starting position when dividing the grid, and may be indicated by a relative position or an absolute position. The grid resolution may indicate the scale used when dividing the grid. It is understood that the grid resolution may not be indicated, and a default resolution may be used.

[0185] 4. Channel state prediction values ​​can be indicated by multipath information, such as power delay profile (PDP) and channel impulse response (CIR). This channel state prediction value is calculated by the target-aware communication node described in Figures 4A to 4D along the transmission path from the base station to the terminal at each location.

[0186] 5. Associated scatterer information or scatterer group information, information about the scatterer or scatterer group associated with the transmission path when estimating the channel state prediction value of the grid. In one possible scenario, the scatterer information may include the identifier of the scatterer and / or the location information of the scatterer. The location information of the scatterer may be indicated by the coordinate information of the grid or by an absolute position or a relative position. Optionally, the scatterer information may also include acquisition time information, such as a timestamp, indicating that the sensing communication node in FIG4B sensed the scatterer at the timestamp.

[0187] 6. RF channel quality, the RF channel quality corresponding to the grid is equivalent to the perceived accuracy service quality. Optionally, the RF channel quality corresponding to the grid may have an initial value, which may be set to a preset minimum value, or may be determined based on the acquisition time information of the scatterer information or the scatterer group information. For example, the greater the time difference between the acquisition time information and the current time, the earlier the time of evaluating the RF channel quality is, and thus the RF channel quality may become inaccurate. Therefore, the lower the initial value, the smaller the time difference between the acquisition time information and the current time, the later the time of evaluating the RF channel quality is, and thus the RF channel quality may not change much. Therefore, the higher the initial value. The RF channel quality can be updated through the measurement process shown in FIG6 .

[0188] 7. RF channel mapping data application quality, also known as perception-assisted communication quality, refers to the quality feedback of communication in a corresponding area, such as the first location, after using the current RF channel mapping data, such as the RF channel mapping data perception-assisted communication shown in Table 1. Optionally, the RF channel mapping data application quality can be updated through the RF channel mapping data application quality measurement process shown in Figure 8, which is described below.

[0189] Referring to Figure 8, an exemplary flow chart of a method for assessing the application quality of radio frequency channel mapping data provided in an embodiment of the present application may include the following operations. In this method, a first communication device in the aforementioned perception communication node may initiate a radio frequency channel quality assessment to a second communication device in the perception communication node. Figure 8 illustrates this using an example in which the first communication device is a base station and the second communication device is a terminal.

[0190] S801: The base station sends a quality measurement request to the terminal.

[0191] Correspondingly, the terminal receives a quality measurement request from the base station.

[0192] In one possible scenario, the quality measurement request may be a radio frequency channel mapping data application request, which is used to request or instruct the terminal to perceive auxiliary communication based on the radio frequency channel mapping data, such as allowing the terminal to perform positioning, beamforming or communication based on the radio frequency channel mapping data.

[0193] In one possible implementation, S801 may be performed when the RF channel quality meets the second requirement. If the RF channel mapping data is stored in the LMF or SMF, the LMF or SMF may send a quality measurement request to the base station when the RF channel quality meets the second requirement, and the base station may perform S801.

[0194] [Corrected 20.02.2025 according to Rule 91] Optionally, the embodiment shown in FIG8 may further include the following operation S802.

[0195] S802: The terminal sends a quality measurement response to the base station.

[0196] Correspondingly, the base station receives a quality measurement response from the terminal.

[0197] In one possible scenario, the quality measurement response may be a radio frequency channel mapping data application response, used to indicate that the terminal can perceive auxiliary communication based on the radio frequency channel mapping data, or used to instruct the base station to send radio frequency channel mapping data. Optionally, the base station may send a quality measurement response to the LMF or SMF.

[0198] S803: The base station sends radio frequency channel mapping data to the terminal.

[0199] Correspondingly, the terminal receives radio frequency channel mapping data from the base station.

[0200] For example, the base station may send the radio frequency channel mapping data shown in Table 1 to the terminal, where the radio frequency channel mapping data may include relevant data of M positions, where the M positions may include the first position and the aforementioned second position. In one possible scenario, if the radio frequency channel mapping data is stored in an LMF or an SMF, the LMF or the SMF may send the radio frequency channel mapping data to the base station, and the base station may execute S803.

[0201] S804: The terminal perceives auxiliary communication based on the radio frequency channel mapping data.

[0202] For example, the terminal can perform beamforming, positioning, or communication based on the radio frequency channel mapping data.

[0203] S805: The terminal sends the radio frequency channel mapping data application quality to the base station.

[0204] Correspondingly, the base station receives the application quality of the radio frequency channel mapping data from the terminal.

[0205] The terminal can determine the application quality of the RF channel mapping data based on the quality of service (QOS) during the communication process, the confirmation response (ACK) or non-acknowledgement response (NACK) during the communication process, and the positioning result as the confidence level. For example,

[0206] In one possible implementation, if the application quality of the RF channel mapping data does not meet the third requirement, it can be considered that the application quality of the RF channel mapping data does not meet expectations, and this problem may be caused by the base station compressing the RF channel mapping data and sending it to the terminal in order to reduce transmission pressure, and the terminal then expands it, or it may be caused by the parameters selected by the base station when generating the RF channel mapping data, such as the communication link is inaccurate. Therefore, the base station can adjust the compression method of the RF channel mapping data or the parameters selected when generating the RF channel mapping data, such as the communication link, and send the adjusted RF channel mapping data to the terminal. The terminal can perform perception-assisted communication based on the adjusted RF channel mapping data. If the application quality of the RF channel mapping data meets the first requirement, it can be considered that the accuracy of the RF channel mapping data is high, and the terminal can continue to perform perception-assisted communication based on the RF channel mapping data.

[0207] It is understandable that the RF channel mapping data application quality can be determined based on the number of ACKs, the number of NACKs, the positioning results, or QOS, or the RF channel mapping data application quality can be the number of ACKs, the number of NACKs, the positioning results, or QOS itself, which is not specifically limited in this application. Among them, if the RF channel mapping data application quality does not meet the third requirement, it can be considered that the RF channel mapping data application quality is greater than or equal to the RF channel mapping data application quality threshold, or the RF channel mapping data application quality is less than or equal to the RF channel mapping data application quality threshold.

[0208] In one possible scenario, if the RF channel mapping data application quality is determined based on the number of ACKs, the number of NACKs, the positioning result, or the QOS, then the RF channel mapping data application quality can be 1%, 15%, or the like. In another possible scenario, if the RF channel mapping data application quality is the number of ACKs, the number of NACKs, the positioning result, or the QOS itself, taking the case where the RF channel mapping data application quality is the number of NACKs as an example, the RF channel mapping data application quality threshold can be 1, 2, or 3, etc., which is not specifically limited in this application.

[0209] Based on the above scheme, if the application quality of the RF channel mapping data does not meet the third requirement, it can be considered that the compression method of the RF channel mapping data is incorrect, or the parameters selected when generating the RF channel mapping data are inaccurate, then the performance of the terminal for perception-assisted communication based on the RF channel mapping data is low. Therefore, the base station can adjust the compression method of the RF channel mapping data or the parameters selected when generating the RF channel mapping data, in order to improve the performance of perception-assisted communication.

[0210] It should be noted that, in the embodiments of the present application, FIG5, FIG6 and FIG8 can be implemented as separate embodiments, or any two or three embodiments can be combined to form one embodiment.

[0211] Referring to Figure 9, an exemplary flow chart of a radio frequency data assessment method provided in an embodiment of the present application may include the following operations. In this method, a first communication device in the aforementioned perceptual communication node may initiate a radio frequency channel quality assessment to a second communication device in the perceptual communication node. Figure 9 illustrates this using an example where the first communication device is a base station and the second communication device is a terminal.

[0212] S901: The base station sends a quality measurement request to the terminal.

[0213] Correspondingly, the terminal receives a quality measurement request from the base station.

[0214] 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.

[0215] In one possible scenario, if the radio frequency channel mapping data is stored by the LMF or SMF, then in S901 the LMF or SMF may send a quality measurement request to the base station, and the base station may send a quality measurement request to the terminal.

[0216] S902: The terminal sends one or more of scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the base station.

[0217] Accordingly, the terminal receives one or more of the scatterer quality, the radio frequency channel quality, or the radio frequency channel mapping data application quality from the base station.

[0218] For example, the terminal may send one of the scatterer quality, the RF channel quality, or the RF channel mapping data application quality to the base station. For another example, the terminal may send multiple of the scatterer quality, the RF channel quality, or the RF channel mapping data application quality to the base station. Exemplarily, the terminal may send the scatterer quality and the RF channel quality to the base station; the terminal may send the scatterer quality and the RF channel mapping data application quality to the base station; the terminal may send the RF channel quality and the RF channel mapping data application quality to the base station; the terminal may send the scatterer quality, the RF channel quality, and the RF channel mapping data application quality to the base station.

[0219] In a possible implementation, when the terminal sends multiple items of scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the base station, one or two of the multiple items meet the first sending condition.

[0220] For example, when the terminal sends the scatterer quality and the RF channel quality to the base station, one or two of the multiple items may satisfy the first sending condition. For example, the scatterer quality satisfies the first requirement. For example, the terminal and the base station will perform RF channel quality evaluation only when the scatterer quality satisfies the first requirement, and the terminal will send the RF 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 RF channel quality evaluation. The base station will re-acquire the environment reconstruction result and re-evaluate the scatterer quality with the terminal until the scatterer quality meets the first requirement. The terminal and the base station will perform RF channel quality evaluation and the terminal will send the RF 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 RF channel quality to the base station. For example ...

[0221] For another example, when the terminal sends the scatterer quality and the RF channel data application quality to the base station, one or two of the multiple items satisfying the first sending condition may be one of the multiple items satisfying the first sending condition, such as the scatterer quality satisfying the first requirement. This can be implemented with reference to the embodiment shown in FIG5 . When the scatterer quality satisfies the first requirement, the terminal and the base station will perform an evaluation of the RF channel mapping data application quality, and the terminal will send the RF 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 an evaluation of the RF channel mapping data application quality. The base station will re-acquire the environment reconstruction result and re-evaluate the scatterer quality with the terminal until the scatterer quality meets the first requirement. The terminal and the base station will perform an evaluation of the RF channel mapping data application quality, and the terminal can send the RF 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 RF channel mapping data application quality to the base station. This can be implemented with reference to the embodiment shown in FIG5 .

[0222] For another example, when the terminal sends the RF channel quality and the RF channel data application quality to the base station, one or two of the multiple items satisfying the first sending condition may be one of the multiple items satisfying the first sending condition, such as the RF channel quality meeting the second requirement. This can be implemented with reference to the embodiment shown in FIG6 . When the RF channel quality meets the second requirement, the terminal and the base station will perform an evaluation of the RF channel mapping data application quality, and the terminal will send the RF channel mapping data application quality 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 of the RF channel mapping data application quality. The base station will reacquire the RF channel mapping data and re-evaluate the RF channel quality with the terminal until the RF channel quality meets the second requirement. The terminal and the base station will perform an evaluation of the RF channel mapping data application quality, and the terminal can send the RF channel mapping data application quality to the base station. That is to say, when the RF channel quality does not meet the second requirement, the terminal will adjust the RF channel quality to meet the second requirement and then send the RF channel mapping data application quality to the base station. This can be implemented with reference to the embodiment shown in FIG6 .

[0223] For another example, when the terminal sends the scatterer quality, RF channel quality and RF channel application quality to the base station, one or two of the multiple items may meet the first sending condition. For example, the scatterer quality meets the first requirement, and the RF channel direct connection meets the second requirement. This can be implemented with reference to the embodiments shown in Figures 5 and 6. Only when the scatterer quality meets the first requirement and the RF channel quality meets the second requirement will the terminal and the base station evaluate the application quality of the RF channel mapping data, and only then will the terminal send the application quality of the RF channel mapping data to the base station. In the case that 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 RF channel quality to the base station. This can be implemented with reference to the embodiment shown in Figure 5. Similarly, in the case that the scatterer quality does not meet the second requirement, the terminal will adjust the RF channel quality to meet the second requirement and then send the application quality of the RF channel mapping data to the base station. This can be implemented with reference to the embodiment shown in Figure 6.

[0224] In an embodiment of the present application, if the application quality of the RF channel mapping data does not meet the third requirement, it can be considered that the compression method of the RF channel mapping data is incorrect, or the parameters selected when generating the RF channel mapping data are inaccurate, then the performance of the terminal for perception-assisted communication based on the RF channel mapping data is low, so the base station can adjust the compression method of the RF channel mapping data or the parameters selected when generating the RF channel mapping data, in order to improve the performance of perception-assisted communication.

[0225] When the application quality of the RF channel mapping data meets the third requirement, the terminal can use the RF channel mapping data, such as the first RF channel mapping data, to perform perception-assisted communication. If the application quality of the RF channel mapping data does not meet the third requirement, it can be considered that the accuracy of the RF 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 RF channel mapping data and sends it to the terminal, and the terminal then expands it, or it may be caused by the parameters selected by the base station when generating the RF channel mapping data, such as inaccurate communication links. Therefore, when the base station determines that the application quality of the RF channel mapping data does not meet the third requirement, the base station can adjust the compression method of the RF channel mapping data or the parameters selected when generating the RF channel mapping data, and send the adjusted RF channel mapping data, such as the second RF channel mapping data, to the terminal. The terminal can perform perception-assisted communication based on the adjusted RF channel mapping data.

[0226] In one possible scenario, base station processing operations may be performed by the CU, and base station transceiver operations may be performed by the DU or RU. For example, the CU may generate a quality measurement request and send it to the DU. The DU may send the quality measurement request, or the DU may send the quality measurement request to the RU, which then sends it.

[0227] The DU may receive one or more of the scatterer quality, the RF channel quality, or the RF channel mapping data application quality, and send the scatterer quality, the RF channel quality, or the RF channel mapping data application quality to the CU. The CU determines whether it is necessary to reacquire the environment reconstruction result, whether it is necessary to regenerate the RF channel mapping data, or whether it is necessary to reselect the parameters contained in the RF channel mapping data and / or the compression method of the RF channel mapping data. Optionally, the RU may receive one or more of the scatterer quality, the RF channel quality, or the RF channel mapping data application quality, and send the scatterer quality, the RF channel quality, or the RF channel mapping data application quality to the DU.

[0228] In another possible scenario, the base station's processing operations can be performed by the CU-CP, and the base station's transceiver operations can be performed by the DU or RU. For example, the CU-CP can perform the above-mentioned CU operations, the DU can perform the above-mentioned DU operations, and the RU can perform the above-mentioned RU operations.

[0229] 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.

[0230] As can be seen from the embodiment shown in FIG9 , the RF data evaluation method provided in the embodiment of the present application employs a multi-layered evaluation approach, such as scatterer quality assessment, RF channel quality assessment, and RF channel mapping data application quality assessment, which can improve the reliability and service performance of RF channel mapping data. The following describes the RF data evaluation method provided in the embodiment of the present application in conjunction with FIG9 .

[0231] As shown in Figure 10, perceptual communication nodes, such as base stations, terminals, and TRPs, can acquire environmental information through perception and determine environmental reconstruction results. This can be implemented with reference to the embodiments shown in Figures 4A and 4B. Base stations and terminals can perform scatterer quality assessments, which can be implemented with reference to the embodiment shown in Figure 5. If the scatterer quality meets the first requirement, the terminal and base station can generate RF channel mapping data, which can be implemented with reference to the embodiments shown in Figures 4C and 4D.

[0232] In one possible scenario, after generating the RF channel mapping data, the terminal and the base station may perform an RF channel quality assessment, which may be implemented with reference to the embodiment shown in FIG6 . If the RF channel quality does not meet the second requirement, the base station may return to the process of generating the RF channel mapping data. If the RF channel quality meets the second requirement, the base station may determine the parameters included in the RF channel mapping data and / or determine a compression method for the RF channel mapping data, and then send the RF channel mapping data to the terminal. It is understood that the RF channel mapping data may be sent compressed. The terminal may recover the compressed RF channel mapping data and perceive the supplementary communication based on the RF channel mapping data. The terminal may determine the application quality of the RF channel mapping data for perceiving the supplementary communication based on 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 perceiving the supplementary communication. If the application quality of the RF channel mapping data does not meet the third requirement, the base station returns to the process of determining the parameters used to generate the RF channel mapping data and / or determining the compression method for the RF channel mapping data.

[0233] In another possible scenario, 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. 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 executing 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.

[0234] In one possible implementation, the RF channel mapping data can be managed by various functions and modules in the integrated sensing and communication / joint communication and sensing (ISAC) system. It is understandable that the ISAC system can be set in a base station, terminal, TRP or CPE. Referring to Figure 11, the ISAC wireless data acquisition module can obtain 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 transferring request to the sensing result and RF mapping data storage module, requesting 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.
