[0002] This application claims priority to Chinese Patent Application No. 202410035381.0, filed on January 9, 2024, entitled "A Radio Frequency Data Evaluation Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of wireless communication technology, and in particular to a radio frequency data evaluation method and apparatus. Background Technology

[0004] Currently, leveraging environmental information obtained through sensing to achieve higher spectral efficiency or to obtain more robust, resilient, and easily recoverable networks has become a major research topic in sensing-assisted communication (SAM). Sensing-assisted channel prediction and sensing-assisted localization are important topics in SAM, using environmental information obtained through sensing to predict radio frequency channel conditions for communication and localization.

[0005] However, environmental information obtained through sensing may contain certain errors. These errors may arise from differences between the perceived environmental information and the actual environmental information or electromagnetic environment, or from losses due to compression of the perceived environmental information before transmission and subsequent unpacking to reduce communication load. Therefore, the accuracy of the 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] This application provides a radio frequency data evaluation method and apparatus to improve the performance of sensing-assisted communication.

[0007] Firstly, a radio frequency (RF) data evaluation method is provided. This method can be executed by a first communication device or a chip / chip system. The first communication device can be a terminal device or a network device. The method is illustrated using an example executed by a first communication device. In this method, the first communication device receives a quality measurement request. Based on the quality measurement request, the first communication device sends one or more of the following: scatterer quality, RF channel quality, and RF channel mapping data application quality. The scatterer quality characterizes the accuracy of the location of the scatterers included in the first RF channel mapping data; the RF channel quality characterizes the deviation between the channel state measurement value and the channel state prediction value included in the first RF channel mapping data; and the RF channel mapping data application quality characterizes the quality of use of the first RF channel mapping data.

[0008] Based on the above scheme, the first communication device can obtain radio frequency channel mapping data by utilizing the environmental information obtained through sensing, and 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. In this way, the accuracy of the radio frequency channel mapping data can be evaluated, and whether the radio frequency channel mapping data can be applied to sensing-assisted communication such as sensing-assisted channel prediction and sensing-assisted positioning can be evaluated to improve the performance of sensing-assisted communication.

[0009] In one possible implementation, the first communication device transmits multiple factors including scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality. One or two of these factors satisfy a first transmission condition. For example, if the multiple factors include scatterer quality and radio frequency channel quality, one or two of the factors satisfying the first transmission condition could mean that only one factor satisfies the first transmission condition, such as the scatterer quality satisfying a first requirement. Another example: if the multiple factors include scatterer quality and radio frequency channel mapping data application quality, one or two of the factors satisfying the first transmission condition could mean that only one factor satisfies the first transmission condition, such as the scatterer quality satisfying a first requirement. Yet another example: if the multiple factors include radio frequency channel quality and radio frequency channel mapping data application quality, one or two of the factors satisfying the first transmission condition could mean that only one factor satisfies the first transmission condition, such as the radio frequency channel quality satisfying a second requirement. Finally, if the multiple factors include scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality, one or two of the factors satisfying the first transmission condition could mean that both factors satisfy the first transmission condition, such as the scatterer quality satisfying the first requirement and the radio frequency channel quality satisfying the second requirement.

[0010] Based on the above scheme, the first communication device can transmit multiple aspects of the scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality to the second communication device when one or two of these aspects meet the first transmission condition. It is understood that if one or two of these aspects do not meet the first transmission condition, such as if the multiple aspects include scatterer quality and radio frequency channel quality, and the scatterer quality does not meet the first requirement, then the radio frequency channel quality may not be transmitted; if the multiple aspects include scatterer quality and radio frequency channel mapping data application quality, and the scatterer quality does not meet the first requirement, then the radio frequency channel quality may not be transmitted; if the multiple aspects include scatterer quality and radio frequency channel mapping data application quality, and the scatterer quality does not meet the first requirement, then the radio frequency channel quality may not be transmitted; if the multiple aspects include scatterer quality and radio frequency channel mapping data application quality, and the radio frequency channel quality does not meet the second requirement, then the radio frequency channel quality may not be transmitted, thus reducing system overhead.

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

[0012] Based on the above scheme, if the scatterer quality meets the first requirement, the accuracy of the estimated position of the scatterer can be considered high. Therefore, the accuracy of the radio frequency channel mapping data generated based on the environmental reconstruction results including the scatterer will also be relatively high. Thus, radio frequency channel quality can be evaluated with the second communication device, and the radio frequency channel quality can be sent to the second communication device. If the scatterer quality does not meet the first requirement, the first and second communication devices will not perform the radio frequency channel quality evaluation process. Therefore, the first communication device will not send the radio frequency channel quality to the second communication device, which can reduce system overhead.

[0013] In one possible implementation, multiple factors, including scatterer quality and radio frequency channel mapping data application quality, satisfy the first transmission condition, including scatterer quality satisfying the first requirement.

[0014] Based on the above scheme, if the scatterer quality meets the first requirement, the accuracy of the estimated position of the scatterer can be considered high. Therefore, the accuracy of the radio frequency channel mapping data generated based on the environmental reconstruction results including the scatterer will also be relatively high. Thus, the radio frequency channel mapping data can be used for sensing-assisted communication. The first communication device can evaluate the application quality of the radio frequency channel mapping data with the second communication device, and can then send the application quality information to the second communication device. If the scatterer quality does not meet the first requirement, neither the first nor the second communication device will evaluate the application quality of the radio frequency channel mapping data. Therefore, the first communication device will not send the application quality information to the second communication device, which can reduce system overhead.

[0015] In one possible implementation, multiple factors, including radio frequency channel quality and radio frequency channel mapped data application quality, satisfy the first transmission condition, including radio frequency channel quality satisfying the second requirement.

[0016] Based on the above scheme, if the radio frequency channel quality meets the second requirement, the accuracy of the radio frequency channel mapping data can be considered high. Therefore, the radio frequency channel mapping data can be used for sensing-assisted communication. The first communication device can evaluate the application quality of the radio frequency channel mapping data with the second communication device, and thus send the application quality information of the radio frequency channel mapping data to the second communication device. If the radio frequency channel quality does not meet the second requirement, the first and second communication devices will not evaluate the application quality of the radio frequency channel mapping data. Therefore, the first communication device will not send the application quality information of the radio frequency channel mapping data to the second communication device, which can reduce system overhead.

[0017] In one possible implementation, multiple factors, including scatterer quality, radio frequency channel quality, and radio frequency channel mapped data application quality, satisfy the first transmission condition, which includes scatterer quality satisfying a first requirement and radio frequency channel quality satisfying a second requirement.

[0018] Based on the above scheme, if the scatterer quality meets the first requirement and the radio frequency channel quality meets the second requirement, the accuracy of the radio frequency channel mapping data can be considered high. Therefore, the radio frequency channel mapping data can be used for sensing-assisted communication. The first communication device can evaluate the application quality of the radio frequency channel mapping data with the second communication device, and thus send the application quality of the radio frequency channel mapping data to the second communication device. If the scatterer quality does not meet the first requirement, the first and second communication devices will not evaluate the radio frequency channel quality or the application quality of the radio frequency channel mapping data. The first communication device will not send the radio frequency channel quality and the application quality of the radio frequency channel mapping data to the second communication device, which can reduce system overhead. If the scatterer quality meets the first requirement, but the radio frequency channel quality does not meet the second requirement, the first and second communication devices will not evaluate the application quality of the radio frequency channel mapping data, and the first communication device will not send the application quality of the radio frequency channel mapping data to the second communication device, which can reduce system overhead.

[0019] In one possible implementation, before the first communication device transmits the radio frequency channel quality, if the scatterer quality does not meet the first requirement, the scatterer quality is adjusted to meet the first requirement before transmitting the radio frequency channel quality.

[0020] Based on the above scheme, if the scatterer quality does not meet the first requirement, the first communication device may not transmit the radio frequency channel quality, thereby reducing the system overhead. After adjusting the scatterer quality to meet the first requirement, the radio frequency channel quality is transmitted to evaluate the accuracy of the generated radio frequency channel mapping data.

[0021] In one possible implementation, before the first communication device transmits the radio frequency channel mapping data application quality, if the scatterer quality does not meet a first requirement, the scatterer quality is adjusted to meet the first requirement before transmitting the radio frequency channel mapping data application quality. Alternatively, before transmitting the radio frequency channel mapping data application quality, if the radio frequency channel quality does not meet a second requirement, the radio frequency channel quality is adjusted to meet the second requirement before transmitting the radio frequency channel mapping data application quality.

[0022] Based on the above scheme, if 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 radio frequency channel mapping data to apply the quality, thereby reducing the system overhead. After adjusting the scatterer quality to meet the first requirement or adjusting the radio frequency channel quality to meet the second requirement, the radio frequency channel mapping data is used for sensing-assisted communication to evaluate the application quality of the generated radio frequency channel mapping data.

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

[0024] Based on this scheme, if the application quality of the RF channel mapping data does not meet the third requirement, the accuracy of the RF channel mapping data can be considered low. This problem may be due to the second communication device compressing the RF channel mapping data before sending it to the first communication device to reduce transmission load, and then the first communication device re-unpacking it. Alternatively, it may be due to the parameters selected by the second communication device when generating the RF channel mapping data, such as inaccurate communication links. 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] Secondly, a radio frequency (RF) data evaluation method is provided. This method can be executed by a second communication device or a chip / chip system. The second communication device can be a terminal device or a network device. The method is illustrated using an example executed by a second communication device. In this method, the second communication device sends a quality measurement request. The second communication device receives one or more of the following: scatterer quality, RF channel quality, and RF channel mapping data application quality. The scatterer quality characterizes the accuracy of the scatterer's position included in the first RF channel mapping data; the RF channel quality characterizes the deviation between the channel state measurement value and the channel state prediction value included in the first RF channel mapping data; and the RF channel mapping data application quality characterizes the quality of use of the first RF channel mapping data.

[0026] In one possible implementation, the second communication device receives multiple factors including scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality. These factors satisfy a first transmission condition.

[0027] In one possible implementation, multiple factors include scatterer quality and radio frequency channel quality, and satisfying the first transmission condition includes scatterer quality satisfying a first requirement.

[0028] In one possible implementation, multiple factors, including scatterer quality and radio frequency channel mapping data application quality, satisfy the first transmission condition, including scatterer quality satisfying the first requirement.

[0029] In one possible implementation, multiple factors, including radio frequency channel quality and radio frequency channel mapped data application quality, satisfy the first transmission condition, including radio frequency channel quality satisfying the second requirement.

[0030] In one possible implementation, multiple factors, including scatterer quality, radio frequency channel quality, and radio frequency channel mapped data application quality, satisfy the first transmission condition, which includes scatterer quality satisfying a first requirement and radio frequency channel quality satisfying a second requirement.

[0031] In one possible implementation, if the application quality of the radio frequency channel mapping data does not meet the third requirement, the second communication device sends second radio frequency channel mapping data. The parameters contained in the second radio frequency channel mapping data are different from those contained in the first radio frequency channel mapping data, and / or the compression method of the second radio frequency channel mapping data is different from that of the first radio frequency channel mapping data.

[0032] Thirdly, a communication device is provided, comprising: a processing unit and a transceiver unit.

[0033] The transceiver unit is used to receive quality measurement requests. The processing unit is used to determine one or more of the following based on the quality measurement requests: scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality. The scatterer quality characterizes the accuracy of the location 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 quality of use of the first radio frequency channel mapping data.

Alternatively, the transceiver unit is further configured to, before transmitting the radio frequency channel mapping data application quality, adjust the radio frequency channel quality to meet the second requirement if the radio frequency channel quality does not meet the second requirement, and then transmit the radio frequency channel mapping data application quality.

[0041] In one possible implementation, if the application quality of the radio frequency channel mapping data does not meet the third requirement, the transceiver unit is also used to receive second radio frequency channel mapping data, wherein the parameters contained in the second radio frequency channel mapping data are different from those contained in the first radio frequency channel mapping data and / or the compression method of the second radio frequency channel mapping data is different from that of the first radio frequency channel mapping data.

[0042] Fourthly, a communication device is provided, including a processing unit and a transceiver unit.

[0043] The processing unit generates a quality measurement request. The transceiver unit sends the quality measurement request. The transceiver unit also receives one or more of the following: scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality.

[0077] To facilitate understanding of the technical solutions provided in the embodiments of this application, the following describes the technical terms involved in the embodiments of this application.

[0078] 1) Sensing, also known as wireless sensing, refers to emitting electromagnetic energy into space and calculating information about objects by receiving the reflected electromagnetic waves. This includes parameters such as position, direction, height, speed, size, and path of motion, as well as detecting the object's internal and external shape and structure. 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 penetrability and security, can serve as an important alternative technology for security inspection, concealed object detection, and environmental reconstruction, as shown in Figure 1.

[0079] 2) Integrated communication and sensing systems, also known as integrated sensing and sensing systems, refer to the fusion of electromagnetic signals used for communication and electromagnetic signals used for sensing. Traditionally, active positioning targets primarily consisted of terminal devices capable of emitting electromagnetic waves, such as mobile phones, vehicles, and Internet of Things (IoT) devices. Virtual environment reconstruction targets further include passive objects, such as buildings, urban infrastructure (billboards, bridges, etc.), and traffic conditions (vehicles, bicycles). By receiving electromagnetic wave signals propagating through the spatial environment, the composition of the spatial environment is determined. Through the detection and reconstruction of the virtual environment (active and passive objects and devices), further assisted positioning or sensing-assisted communication performance enhancement can be achieved. Network devices and terminal devices are the main devices for virtual environment reconstruction. The quality of sensing is related to sensing resources, space, time, frequency band, power consumption, and site. The site can refer to network devices, terminal devices, or wireless terminal access equipment (customer premise equipment, CPE), etc.

[0080] For example, spatial parameters can include the number of beams, which can affect the sensing angular range. Temporal parameters include the sensing symbol length, which can affect the sensing azimuth accuracy. Frequency band includes the sensing bandwidth, which can affect the sensing range accuracy. Power consumption includes the sensing signal power, which can affect the sensing range. The communication capacity that a site can include can affect the sensing fusion accuracy.

[0081] Based on whether the transmitting and receiving ends of the sensing signal are co-located or disparate, sensing can be categorized into monostatic, bistatic, and multistatic systems. Multistatic systems are generally hybrid systems composed of monostatic and bistatic components, and two typical integrated communication and sensing system architectures are shown in Figures 2A and 2B. It can be understood that monostatic sensing can also be called single-site sensing, meaning sensing is performed through a single station. Similarly, multistatic sensing can also be called multi-site sensing, meaning sensing is performed through two or more stations.

[0082] Figure 2A illustrates a single-base communication and sensing integrated system. In this system, the sensing transmitter and receiver are located in the same position, and the sensing signal can be represented by data payload, thus the sensing function does not consume communication resources. Furthermore, since the transmission and reception originate from the same source, there are no synchronization or other non-ideal factors, resulting in good sensing algorithm complexity and estimation accuracy. Because single-base environment reconstruction uses self-transmission and self-reception, the range of detectable signal angles is strongly correlated with the environmental incident angle; the reflected signal from objects attenuates rapidly as the incident angle increases. That is, the viewing angle range of single-base environment reconstruction is significantly affected by the material and placement angle of the target object. Due to the use of single-base sensing, most components of the echo signal are single bounces, satisfying radar assumptions. When solving for the environmental space, the ill-conditioned equation problem is smaller, resulting in higher accuracy in solving for the spatial environment.

[0083] Figure 2B illustrates a dual-base sensing and communication integrated system. In this system, the sensing receiver and transmitter are located in different positions, and the sensing signal requires a dedicated pilot or a known signal, thus consuming communication resources. Furthermore, due to the different sources of transmission and reception, there are non-ideal factors such as synchronization and phase noise, resulting in poor complexity and estimation accuracy of the sensing algorithm, necessitating complex calibration algorithms. In dual-base sensing, the use of self-transmission and external reception allows for a wider detection angle, and the sensing viewpoint coverage expands as the terminal moves. Additionally, the echo signal is rich in components, possessing numerous multiple reflection paths (bounce ≥ 2) and high power. In scattering-rich urban spaces, these numerous multiple reflection paths introduce ill-conditioned equations, leading to shadow spaces and erroneous solutions when solving for the virtual environment.

[0084] The technical solutions of this 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, etc., without limitation.

[0085] Figure 3 is a schematic diagram of the architecture of the communication system 1000 applied in an embodiment of this application. As shown in Figure 3, the communication system includes a wireless access network 100. The wireless access network 100 may include at least one network device (110a and / or 110b in Figure 3) and at least one terminal device (at least one of 120a-120j in Figure 3). The terminal device is wirelessly connected to the access network device, and the access network device is wirelessly or wiredly connected to the core network device. Terminal devices and network devices can be interconnected via wired or wireless means. Figure 3 is only a schematic diagram; the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 3.

[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 functions for terminal devices; it is called RAN equipment. 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 5G mobile communication system, a next-generation base station in a 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, for example, it can be a central unit (CU) or a distributed unit (DU). The CU here performs the functions of the radio resource control protocol and packet data convergence protocol (PDCP) of the base station, and can also perform the functions of the service data adaptation protocol (SDAP). The DU performs the functions of the radio link control layer and medium access control (MAC) layer of the base station, and can also perform some or all of the physical layer functions. For specific descriptions of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The network equipment can be a macro base station (as shown in Figure 3, 110a), a micro base station or an indoor station (as shown in Figure 3, 110b), or a relay node or donor node, etc. The embodiments of this application do not limit the specific technology or specific equipment form used in the network equipment.

[0087] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0088] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open radio access network (ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0089] A terminal device is a user-side device with wireless transceiver capabilities. Terminal devices can also be called user equipment (UE), mobile station, mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.

[0090] Network devices and terminal devices can be fixed in location or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of the 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 that access the wireless access network 100 via 120i, terminal device 120i is a network device; however, for network device 110a, 120i is a terminal device. That is, 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a network device-to-network device interface protocol. In this case, relative to 110a, 120i is also a network device. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 3 can be called communication devices with network device functions, and 120a-120j in Figure 3 can be called communication devices with terminal device functions.

[0092] In the embodiments of this application, the functions of the network device can be executed by modules (such as chips) within the network device, or by a control subsystem that includes network device functions. This control subsystem, including network device functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal device, or by a device that includes terminal device functions. In the following description, the terminal device functions are executed by the terminal, and the network device functions are executed by the base station.

[0093] Currently, leveraging environmental information obtained through sensing to achieve higher spectral efficiency or a more robust, resilient, and easily recoverable network has become a major research topic in sensing-assisted communication (SAM). Sensing-assisted channel prediction and sensing-assisted localization are important topics in SAM, where environmental information obtained through sensing is used to predict radio frequency (RF) channel conditions for communication and localization. The predicted RF channel conditions, derived from the obtained environmental information, can be referred to as RF channel mapping maps, RF channel mapping data, or RF data.

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

[0095] In view of this, embodiments of this application provide a radio frequency (RF) 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 following: scatterer quality, RF channel quality, and RF channel mapping data application quality. The scatterer quality characterizes the accuracy of the scatterer's position included in the first RF channel mapping data; the RF channel quality characterizes the deviation between the channel state measurement value and the channel state prediction value included in the first RF channel mapping data; and the RF channel mapping data application quality characterizes the quality of use of the first RF channel mapping data. Based on this scheme, the first communication device can determine one or more of the scatterer quality, RF channel quality, and RF channel mapping data application quality based on the quality measurement request, thereby evaluating whether the RF channel mapping data can be applied to sensing-assisted communication such as sensing-assisted channel prediction and sensing-assisted positioning, to improve the performance of sensing-assisted communication.

[0096] To facilitate understanding of the technical solutions provided in the embodiments of this application, the following describes the method for obtaining radio frequency channel mapping data in the embodiments of this application.

[0097] In communication systems, wireless sensing technology is used to obtain environmental information to assist in channel prediction, localization, beamforming, and other functions, thereby improving the quality of communication services. The process of using wireless sensing technology to predict and create a radio frequency (RF) channel map is called radio frequency mapping (RF mapping). The map obtained through RF mapping is called the RF channel map. The data corresponding to the RF channel map is called RF channel mapping data.

[0098] Referring to Figure 4A, a physical environment map is shown. In Figure 4A, dashed lines can represent roads. In this embodiment, radio frequency channel mapping data of the physical environment shown in Figure 4A can be obtained. Multiple sensing communication nodes, such as base stations, terminals, transmission and receiving points (TRPs), or CPEs, can exist in this physical environment. The sensing communication nodes can transmit electromagnetic waves or radar signals to obtain environmental reconstruction results, as shown in Figure 4B. For example, the sensing communication nodes can transmit electromagnetic waves or radar signals and receive echo signals, thereby obtaining scattering information in the physical environment. In one possible scenario, the various sensing communication nodes can interact with the acquired scattering information to obtain a higher-precision environmental reconstruction result over a larger area, as shown in Figure 4B. Any one of the aforementioned sensing communication nodes can divide the physical environment map into multiple regions, treating each region as a location. For ease of description, any one of the aforementioned sensing communication nodes is referred to as a target sensing communication node. For example, the target sensing communication node can divide the physical environment map into multiple rectangular regions or grids, as shown in Figure 4C. For example, a target-aware communication node can divide the physical environment map into different circular areas (not shown in the figure). Alternatively, it can divide the physical environment map into different hexagonal areas or cellular areas (not shown in the figure), etc., without specific limitations in this application. It is understood that when a target-aware communication node divides the physical environment map into multiple areas, the resolution of the areas can be predefined or preconfigured by the protocol, such as dividing the physical environment map into multiple areas at resolutions of 5m, 10m, etc., without specific limitations in this application.

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

[0100] A target-aware communication node can assume the presence of a terminal at each location and simulate the transmission path from the base station to the terminal at each location, as shown in Figure 4C. It is understood that the transmission path can include the direct transmission path from the base station to the terminal, or it can include the transmission path after reflection from a scattering object. 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 then calculate the predicted channel state value for each location using the simulated transmission path, as shown in Figure 4D. Exemplarily, the target-aware communication node can use ray tracing tools, electromagnetic calculation tools, or simple mirror reflection-based simulation tools to calculate the predicted channel state value of the transmission path from the base station through the environment to the terminals at each location. Furthermore, the target-aware communication node can obtain the scattering object information associated with each location, that is, the information of the scattering objects traversed from the base station to the terminals at each location. In this way, radio frequency channel mapping data can be obtained.

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

[0102] In one possible scenario, the radio frequency channel mapping data involved in this application embodiment may include the 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 use relative positions, such as distance or angle relative to a base station, or absolute positions, such as latitude and longitude information. Alternatively, the location information may be indicated by grid numbers.

[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 starting position of the grid and / or the grid resolution. The starting position of the grid may indicate the initial position when dividing the grid, and can be indicated by a relative or absolute position. The grid resolution may indicate the scale used when dividing the grid. It is understood that the grid resolution may also be omitted, and a default resolution may be used.

[0104] The multiple sensing and communication nodes existing in the aforementioned physical environment may include a base station. In one possible scenario, the base station's processing operations can be performed by the CU (Control Unit), and its transmit / receive operations can be performed by the DU (Distribution Unit) or RU (Receiving Unit). For example, the CU can generate electromagnetic waves for sensing, and the CU can send these electromagnetic waves to the DU. The DU can then transmit the electromagnetic waves, or the DU can send the electromagnetic waves to the RU, which will then transmit them. Similarly, the DU can receive electromagnetic waves and send them back to the CU. The CU determines the scatterer information or scatterer group information to determine the environmental reconstruction result. Optionally, the RU can receive electromagnetic waves and send them back to the DU.

[0105] In another possible scenario, the base station's processing operations can be performed by the CU-CP, while the base station's transmit and receive operations can be performed by the DU or RU. For example, the CU-CP can generate electromagnetic waves for sensing and send these waves to the DU. The DU can then transmit the electromagnetic waves, or it can send them to the RU for transmission. Similarly, the DU can receive electromagnetic waves and send them to the CU-CP. The CU-CP determines the scatterer information or scatterer group information to determine the environmental reconstruction result. Optionally, the RU can receive electromagnetic waves and send them to the DU.

[0106] Similarly, the target-aware communication node mentioned above could be a base station, a terminal, or a TRP. If the target-aware communication node is a base station, in one possible scenario, the base station's processing operations can be performed by the CU, and the base station's transmit and receive operations can be performed by the DU or RU. For example, the CU can divide the physical environment map into multiple areas, each area as a location, and determine the radio frequency channel mapping data for each location. The CU can send the radio frequency channel mapping data to the DU, and the DU can send the radio frequency channel mapping data to the terminal or core network. Optionally, the DU can send the radio frequency channel mapping data to the RU, and the RU can send the radio frequency channel mapping data to the terminal or core network.

[0107] In another possible scenario, the base station's processing operations can be performed by the CU-CP, while the base station's transmit and receive 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 representing a location, and determine the radio frequency channel mapping data for each location. The CU-CP can send the radio frequency channel mapping data to the DU, which can then send it to the terminal or the core network. Optionally, the DU can send the radio frequency channel mapping data to the RU, which in turn sends it to the terminal or the core network.

[0108] In the O-RAN scenario, the operations performed by the 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, radio frequency channel maps correspond to certain geographical areas and are used to indicate the geographical location and size of multiple areas within that geographical area.

[0111] The geographical region can be a certain area in the real physical world. For example, the geographical region can be represented by longitude, latitude, and altitude. For example, the starting point can be denoted as (x_0, y_0, z_0), and the outdoor scene can be 100m × 100m with this starting point as the reference.

[0112] The multiple regions mentioned above can be regions obtained by dividing the geographical area in a certain way. For example, the above-mentioned 100m×100m geographical area can be divided into 1m×1m regions, resulting in 100×100 regions. Each region is 1m×1m.

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

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

[0115] In one possible implementation, the shape of the region can be a square, or other shapes such as a rectangle, trapezoid, triangle, etc. Alternatively, the shape of the region can also be irregular, without limitation.

[0116] For example, the shape of a region can be defined by a protocol or by a network device. 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. Region sizes, radii, and areas defined by different network devices can be the same or different. The same network device can also define multiple region sizes, multiple region radii, or multiple region areas.

[0117] In one possible implementation, multiple regions can be indexed (e.g., numbered) to identify different regions.

[0118] In one possible scenario, the radio frequency channel map comprises multiple grids, each corresponding to a specific region. It is readily understood that, in this application, the grids involved in the radio frequency channel map may possess at least one of the following attributes: shape, size, area, etc. Specifically, the shape of the grid may be consistent with the shape of the region corresponding to that grid. The size of the grid is proportional to the size of the region corresponding to that grid. The area of ​​the grid is proportional to the area of ​​the region corresponding to that grid. The size of the grid may also be described in other ways, such as resolution.

[0119] In one possible implementation, if the environmental reconstruction results obtained by the sensing communication node are inaccurate—for example, if the location accuracy of the scatterer or scatterer group is low—the accuracy of the radio frequency channel mapping data obtained based on the environmental reconstruction results will also be relatively low. Therefore, in this embodiment, the scatterer quality can be evaluated. It is understood that scatterer quality can characterize the accuracy of the location of the scatterer or scatterer group. Hereinafter, for ease of description, both the scatterer group and the scatterer will be referred to as scatterers. It is understood that the term "scatterer" can also be replaced by "scatterer group" in the following text.

[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 sensing communication node can initiate a scatterer quality assessment to a second communication device in the sensing communication node. Figure 5 illustrates this using the first communication device as a base station and the second communication device as a terminal as an example.

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

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

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

[0124] In one possible scenario, the environmental reconstruction results or RF channel mapping data can be stored in the session management function (SMF) or location management function (LMF) of the base station or core network equipment. If the environmental reconstruction results or RF channel mapping data are stored in the LMF or SMF, the SMF or LMF can initiate a scatterer quality assessment. For example, the SMF or LMF can send a quality measurement request, such as a scatterer quality measurement request, to the base station, which can then execute S501.

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

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

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

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

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

[0130] In one possible scenario, the terminal can obtain the true location of the scatterer. For example, the terminal can obtain the location information of the scatterer on a map of the real physical environment and regard it as the true location of the scatterer. The terminal can determine the mass of the scatterer based on the true location of the scatterer and the estimated location of the scatterer. For example, the terminal can calculate the difference, variance, or squared difference between the true location of the scatterer and the estimated location of the scatterer. The terminal can regard the obtained difference, variance, or squared difference as the mass of the scatterer, or the terminal can determine the mass of the scatterer based on the difference, variance, or squared difference; that is, the terminal can quantify the mass of the scatterer based on the difference, variance, or squared difference.

[0131] In another possible scenario, the terminal can obtain the location of the anchor point. For example, the terminal can store the location of a specific anchor point, such as the location of a building, a streetlight, or a street, where buildings, streetlights, or streets can be considered anchor points. The terminal can estimate the location of the scatterer based on the location of this anchor point. The terminal can determine the mass of the scatterer based on the estimated location of the scatterer obtained from the anchor point location and the predicted location of the scatterer, as described in the preceding descriptions, which will not be repeated here.

[0132] In another possible scenario, the terminal can acquire the location of the scatterer obtained from long-term cumulative measurements. For example, the terminal can acquire the location of the scatterer measured over a period of time, such as a year, a month, or a week. The terminal can calculate the average value of these measurements. Based on this average value and the estimated location of the scatterer, the terminal can determine the mass of the scatterer, as described in the preceding descriptions, which will not be repeated here.

[0133] Optionally, in S502, the terminal may send to the base station the true value of the scatterer's position, the position of the anchor point, or the average value of the scatterer's position obtained from long-term accumulated measurements. The base station, the LMF, or the SMF may determine the scatterer quality based on the true value of the scatterer's position from the terminal, the position of the anchor point, or the scatterer's position obtained from long-term accumulated measurements, as well as the aforementioned estimated scatterer position.

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

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

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

[0137] It is understood that the scatterer quality can be determined based on the aforementioned difference, variance, or squared difference, or the scatterer quality can be the aforementioned difference, variance, or squared difference itself; this application does not impose specific limitations. Wherein, if the scatterer quality does not meet the first requirement, it can be considered that the scatterer quality is greater than or equal to the scatterer quality threshold, or the scatterer quality is less than or equal to the scatterer quality 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 could be 1, 1.5, or 10%, etc. In another possible scenario, if the scatterer quality is the difference, variance, or squared difference itself, then taking the variance as an example, the scatterer quality threshold could be 0.1, 0.01, or 0.5, etc., without specific limitations 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 results. If the scatterer quality meets the first requirement, the scatterer positions contained in the environmental reconstruction results can be considered relatively accurate. Therefore, the RF channel mapping data obtained based on this environmental reconstruction result will also be relatively accurate, improving the accuracy of the RF channel mapping data and thus enhancing the performance of sensing-assisted communication based on 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. In this case, the RF channel mapping data obtained based on the environmental reconstruction results will also be inaccurate. Therefore, RF mapping can be performed without RF channel quality assessment, and there is no need to transmit RF channel quality data to reduce system overhead.

[0140] Optionally, if the base station re-initiates the acquisition of environmental reconstruction results, the base station may adjust sensing resources to improve the accuracy of the environmental reconstruction results. For example, the base station may adjust one or more of the following: transmission reception point (TRP), number of antenna streams, time-domain resources used for sensing, frequency-domain resource bandwidth, and spatial resources.

[0141] In this embodiment, if the scatterer quality at the first location meets the first requirement, it indicates that the scatterer quality meets expectations. Then, the base station can initiate an assessment of the radio frequency (RF) channel quality or an assessment of the RF channel mapping data application quality. It is understood that RF channel quality characterizes the deviation between the channel state measurement value and the channel state prediction value included in the RF channel mapping data, while RF channel mapping data application quality characterizes the quality of use of the RF channel mapping data. The methods for assessing RF channel quality and evaluating the RF channel mapping data application quality are described below with reference to Figures 6 and 7, respectively.

[0142] Referring to Figure 6, an exemplary flowchart of a radio frequency channel quality assessment method provided in an embodiment of this application is shown, which may include the following operations. In this method, the first communication device in the aforementioned sensing communication node can initiate a radio frequency channel quality assessment to the second communication device in the sensing communication node. In Figure 6, the first communication device is used as a base station and the second communication device is used as a terminal for illustration.

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

[0144] Accordingly, 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 radio frequency channel mapping data, such as the radio frequency channel mapping data obtained through the processes shown in Figures 4A to 4D. Alternatively, the radio frequency channel mapping data may have been previously sent to the terminal and stored in the terminal. In S601, the radio frequency channel mapping data may be stored in the base station or in the LMF or SMF in the core network equipment, and the base station may obtain the radio frequency channel mapping data and send it to the terminal.

[0146] In one possible scenario, the base station can send K location-related data to the terminal, such as location information for the K locations, predicted channel states for the K locations, and scatterer information associated with the K locations, including the terminal's initial location. Here, K is an integer greater than or equal to 1. For example, the base station can locate the terminal, or the terminal can send location information to the base station. In this way, the base station can determine the terminal's location and send the K location-related data to the terminal. Optionally, the radio frequency channel mapping data sent by the base station to the terminal may also include grid setting information.

[0147] In one example, the radio frequency channel mapping data involved in this application embodiment may further include reference radio frequency channel quality. It is understood that the reference perceived quality may be an initial value, that is, a reference radio frequency channel quality determined based on the channel state prediction, or the reference radio frequency channel quality may be a radio frequency channel quality that has been updated through the embodiment shown in Figure 6. The radio frequency channel mapping data sent by the base station to the terminal may further include the reference radio frequency channel quality at the aforementioned K locations.

[0148] Optionally, for radio frequency (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 signals used for RF channel quality assessment. This may include one or more of the following: transceiver antenna port number, precoding information, and subcarrier configuration. It is understood that the configuration information of the aforementioned measurement signals may be the configuration information used by the sensing communication node to transmit electromagnetic waves when obtaining the environmental reconstruction results, as shown in Figures 4A and 4B, such as the transceiver antenna port number, precoding information, and subcarrier configuration. This is to reduce errors caused by differences in precoding information, subcarrier configuration, and transceiver antenna port number, thereby improving the accuracy of RF channel quality assessment.

[0149] In one possible implementation, S601 can be executed after the scatterer quality meets the first requirement. If the RF channel mapping data is stored in an LMF or SMF, the LMF or SMF can send a quality measurement request to the base station, and the base station can execute S601.

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

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

[0152] For example, the measurement signal can be a downlink signal such as channel state information (CSI) reference signal (RS) or positioning reference signal (PRS).

[0153] In one possible implementation, the terminal can obtain configuration information of the measurement signal. For example, the terminal can receive configuration information of the measurement signal from a base station. For instance, the base station can send a system message, and the terminal can receive the system message sent by the base station, which may contain the configuration information of the measurement signal.

[0154] It should be noted that when a base station transmits measurement signals, it can do so according to the configuration information of the measurement signal. For example, it can use the transmit / receive antenna port number, precoding information, and subcarrier configuration indicated in the measurement signal configuration information to transmit the measurement signal. Similarly, when a terminal receives measurement signals, it can receive them according to the configuration information of the measurement signal. For example, it can use the transmit / receive antenna port number, precoding information, and subcarrier configuration indicated in the measurement signal configuration information to receive the measurement signal.

[0155] The terminal can measure the measurement signal to obtain channel state measurement values. For example, the terminal can measure the measurement signal to obtain 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., without specific limitations in this application. The terminal can determine the radio frequency channel quality at a first location based on the channel state measurement values ​​and the channel state prediction values ​​at a first location. For example, the terminal determines the radio frequency channel quality by determining the correlation between the channel state measurement values ​​and the channel state prediction values, as described below.

[0156] For example, the channel state prediction value for the first location contained in the radio frequency channel mapping data is determined by R. iThe elements are composed of, indicating the first position (x) i ,y i, z i The multipath component predicted by the environment at point R is expressed by formula (2): 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 (x) indicates that when the terminal's positioning capability or accuracy is good, for example, when the positioning quality exceeds a preset threshold, the global positioning system (GPS) or line-of-sight (LOS) conditions are well evaluated, and therefore (x) can be used to represent (x). ue ,y ue, z ue ) and the corresponding R ue It can be placed in the record stack to represent the truth information in reality.

[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. Let's take Euclidean distance as an example.

[0160] The terminal can determine R i and R ue Correlation S i =f(R) i ,R ue The quality of the radio frequency channel is represented by formula (4):

[0161] Among them, Q R It can be used as a measure of radio frequency channel quality.

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

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

[0164] In one possible scenario, the terminal in S603 can send channel state measurement values ​​to the base station. The base station, LMF, or SMF can determine the radio frequency channel quality based on the channel state measurement values ​​and channel state prediction values, referring to the methods described in formulas (2) to (4). Repeated descriptions will not be repeated.

[0165] In one possible implementation, if the radio frequency (RF) channel quality does not meet the second requirement (e.g., if the RF channel quality is greater than or equal to the RF channel quality threshold), it indicates that the channel state prediction value does not meet expectations, meaning the channel state prediction value is inaccurate. In this case, the base station can 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 can 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 can be set based on empirical values, such as 10 dBM, and this application does not impose any specific limitations.

[0167] In this embodiment, if the radio frequency channel quality meets the second requirement, such as the radio frequency channel quality being less than or equal to the radio frequency channel quality threshold, it indicates that the radio frequency channel quality meets expectations. The base station can update the reference radio frequency channel quality of other locations associated with the scatterer associated with the first location, such as other locations besides the first location, to the aforementioned radio frequency channel quality that meets the second requirement. Hereinafter, the other locations associated with the scatterer associated with the first location are referred to as the second location.

[0168] Referring to Figure 7, a schematic diagram of updating perceived quality is shown. As shown in Figure 7, the terminal can be in a first position (the shaded rectangle shown in Figure 7a). Using the embodiment shown in Figure 6, the radio frequency channel quality at 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 (the black rectangle shown in Figure 7b) through radio frequency channel mapping data. The terminal or base station can then update the reference radio frequency channel quality at the second position to the radio frequency channel quality as well. In other words, the radio frequency channel quality can be updated uniformly by sharing the position of the scatterer associated with the first position.

[0169] In one possible scenario, assuming the scatterers associated with the first location include scatterer A and scatterer B, and the scatterers associated with the second location, such as location X, include scatterer A, scatterer B, and scatterer C, then the first and second communication devices can predict the channel state value R using scatterer A, scatterer B, and scatterer C. iThe contribution of each scatterer is used to determine its weight. Then the radio frequency channel quality Q at position X is determined. R = The mass of scatterer A (RF channel quality) * the weight of scatterer A + the mass of scatterer B (RF channel quality) * the weight of scatterer B + the weight of scatterer C * the mass of scatterer C. The mass of scatterer C can be illustrated by the embodiment shown in Figure 6, except that, in determining the mass of scatterer C, the communication device located at the position associated with scatterer C needs to execute the embodiment shown in Figure 6.

[0170] Based on the above scheme, if the radio frequency (RF) channel quality meets the second requirement, it can be considered that the RF channel quality meets expectations. The RF channel quality can reflect 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 assumed 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 indicates that the location of the scatterer is relatively accurate. Thus, the RF channel quality of the second location associated with the scatterer can be updated based on the RF channel quality, so that the RF channel mapping data can be used for sensing-assisted communication, thereby improving the service performance of the RF channel mapping data.

[0171] In one possible implementation, if the radio frequency channel quality meets the second requirement, it indicates that the radio frequency channel quality meets expectations, meaning the radio frequency channel quality at the first and second positions is relatively accurate. Then, one or more of the relevant data for the first and second positions, such as the predicted channel state values ​​for the first and second positions, the scatterer information associated with the first and second positions, or the radio frequency channel quality at the first and second positions, can be used for sensing-assisted communication. The protocol can enable sensing-assisted communication using the relevant data for the first position in the radio frequency channel mapping data. For example, the base station can send updated radio frequency channel mapping data to the terminal, such as updating the reference radio frequency channel quality to the radio frequency channel quality in S602. The terminal can then use the relevant data for the first and second positions in the updated radio frequency channel mapping data for sensing-assisted communication.

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

[0173] In another possible implementation, if the scatterer quality meets the first requirement and the radio frequency channel quality meets the second requirement, then one or more of the following data related to the first and second positions—such as the channel state prediction values ​​of the first and second positions, the scatterer information associated with the first and second positions, or the radio frequency channel quality of the first and second positions—can be used for sensing-assisted communication. The protocol can enable sensing-assisted communication using the relevant data about the first and second positions in the radio frequency channel mapping data. For example, the base station can send updated radio frequency channel mapping data to the terminal, such as radio frequency channel mapping data updated with the radio frequency channel quality in S603. The terminal can then use the relevant data about the first and second positions in the updated radio frequency channel mapping data for sensing-assisted communication.

[0174] In one possible scenario, the radio frequency channel mapping data sent by the base station to the terminal may include relevant data for M locations. These M locations may include a first location and the aforementioned second location, where M is an integer greater than or equal to 1. For example, the radio frequency channel mapping data sent by the base station to the terminal may include location information for the M locations, channel state prediction values ​​for the M locations, and scatterer information or scatterer group information associated with the M locations. Optionally, the radio frequency channel mapping data sent by the base station to the terminal may also include the aforementioned grid setting information, indicating the starting position of the grid and / or the grid resolution. It is understood that the M locations may be the same as or different from the previously mentioned K locations.

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

[0176] Optionally, the radio frequency channel mapping data sent by the base station to the terminal may also include configuration information of measurement signals used for radio frequency channel quality assessment, which may include one or more of the following: transmit and receive signal antenna port number, precoding information, and subcarrier configuration.

[0177] For example, in this embodiment of the application, the radio frequency channel mapping data sent by the base station to the terminal may include the contents shown in Table 1 below.

[0178] Table 1: An example of radio frequency channel mapping data

[0179] As shown in Table 1, the radio frequency channel mapping data sent by the base station to the terminal may include one or more of the following: configuration information of the measurement signal, grid setting information, location information, channel state prediction values, associated scatterers or scatterer groups, and associated sensing quality. These will be described in detail below.

[0180] 1. The configuration information of the measurement signal may include one or more of the following: transmit and receive antenna port number, precoding information, and subcarrier configuration.

[0181] It is understandable that the configuration information of the above-mentioned measurement signals may be the configuration information used by the sensing communication node to send electromagnetic waves when obtaining the environmental reconstruction results, such as the transmit and receive antenna port number, precoding information, and subcarrier configuration.

[0182] 2. Location information, indicating geographical 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 grid number. In Table 1, the subscript i can be understood as the grid number.

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

[0184] The grid's starting position indicates the initial location from which the grid was created, and can be indicated using either a relative or absolute position. The grid's resolution indicates the scale used when creating the grid. It's understandable that the grid resolution can be left unspecified, with the default resolution used.

[0185] 4. Channel state prediction values ​​can be indicated using multipath information, such as power delay profile (PDP) and channel impulse response (CIR). These channel state prediction values ​​are calculated from the transmission paths taken by the target-aware communication node through the base station to the terminal at each location, as shown in Figures 4A to 4D.

[0186] 5. Associated scatterer information or scatterer group information: Information on the scatterers or scatterer groups associated with the transmission path when estimating the channel state prediction value of the grid. In one possible case, the scatterer information may include the identifier of the scatterer and / or the location information of the scatterer. The location information of the scatterer can be indicated by the grid coordinate information or by absolute or relative position. Optionally, the scatterer information may also include acquisition time information, such as a timestamp, indicating that the sensing communication node in Figure 4B sensed the scatterer at that timestamp.

[0187] 6. Radio Frequency Channel Quality: The radio frequency channel quality corresponding to the grid is equivalent to the perceived accuracy service quality. Optionally, the radio frequency channel quality corresponding to the grid can have an initial value. This initial value can be set to a preset minimum value, or it can be determined based on the acquisition time information of the scatterer information or scatterer group information. For example, a larger time difference between the acquisition time information and the current time indicates that the radio frequency channel quality was evaluated earlier, and therefore the radio frequency 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, indicating that the radio frequency channel quality was evaluated later, and therefore the radio frequency channel quality may not change much; therefore, the higher the initial value. The radio frequency channel quality can be updated through the measurement process shown in Figure 6.

[0188] 7. RF channel mapping data application quality, also known as sensing-assisted communication quality, refers to the communication quality feedback in the corresponding area, such as the first location, after using the current RF channel mapping data (as shown in Table 1) for sensing-assisted communication. 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 will be described below.

[0189] Referring to Figure 8, an exemplary flowchart of a radio frequency channel mapping data application quality assessment method provided in an embodiment of this application is shown, which may include the following operations. In this method, the first communication device in the aforementioned sensing communication node can initiate a radio frequency channel quality assessment to the second communication device in the sensing communication node. In Figure 8, the first communication device is used as a base station and the second communication device is used as a terminal for illustration.

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

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

[0192] In one possible scenario, the aforementioned quality measurement request could be a radio frequency channel mapping data application request, used to request or instruct the terminal to sense 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 can be executed if the radio frequency channel quality meets the second requirement. If the radio frequency channel mapping data is stored in an LMF or SMF, the LMF or SMF can send a quality measurement request to the base station if the radio frequency channel quality meets the second requirement, and the base station can execute S801.

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

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

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

[0197] In one possible scenario, the quality measurement response could be an RF channel mapping data application response, used to indicate that the terminal can sense auxiliary communication based on the RF channel mapping data, or in other words, to instruct the base station to send RF channel mapping data. Optionally, the base station could 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 can send radio frequency channel mapping data as shown in Table 1 to the terminal. This radio frequency channel mapping data may include relevant data for M locations, which may include a first location and the aforementioned second location. In one possible scenario, if the radio frequency channel mapping data is stored in an LMF or SMF, the LMF or SMF can send the radio frequency channel mapping data to the base station, and the base station can execute S803.

[0201] S804: Terminal-based radio frequency channel mapping data sensing-assisted communication.

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

[0203] S805: Application quality of radio frequency channel mapping data sent by the terminal to the base station.

[0204] Correspondingly, the quality of the radio frequency channel mapping data received by the base station from the terminal is improved.

[0205] The terminal can determine the application quality of RF channel mapping data based on the Quality of Service (QoS) during communication, the acknowledgment (ACK) or non-acknowledgment (NACK) during communication, and the location results as confidence levels. 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 is unsatisfactory. This problem may be due to the base station compressing the RF channel mapping data before sending it to the terminal to reduce transmission pressure, and then the terminal re-unpacking it. Alternatively, it may be due to the parameters selected by the base station when generating the RF channel mapping data, such as inaccurate communication links. 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 then perform sensing-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 sensing-assisted communication based on this RF channel mapping data.

[0207] It is understood that the application quality of radio frequency channel mapping data can be determined based on the aforementioned number of ACKs, number of NACKs, location results, or QoS, or the application quality of radio frequency channel mapping data can be the number of ACKs, number of NACKs, location results, or QoS itself; this application does not impose specific limitations. Wherein, if the application quality of radio frequency channel mapping data does not meet the third requirement, it can be considered that the application quality of radio frequency channel mapping data is greater than or equal to the application quality threshold of radio frequency channel mapping data, or the application quality of radio frequency channel mapping data is less than or equal to the application quality threshold of radio frequency channel mapping data.

[0208] In one possible scenario, if the application quality of RF channel mapping data is determined based on the aforementioned number of ACKs, number of NACKs, location results, or QoS, then the application quality of RF channel mapping data can be a value of 1% or 15%, etc. In another possible scenario, if the application quality of RF channel mapping data is determined by the number of ACKs, number of NACKs, location results, or QoS itself, taking the number of NACKs as an example, the application quality threshold of RF channel mapping data can be a value of 1, 2, or 3, etc., without specific limitation in this application.

[0209] Based on the above scheme, if the application quality of the radio frequency channel mapping data does not meet the third requirement, it can be assumed that the compression method of the radio frequency channel mapping data is incorrect, or the parameters selected when generating the radio frequency channel mapping data are inaccurate. In this case, the performance of the terminal in performing sensing-assisted communication based on the radio frequency channel mapping data will be low. Therefore, the base station can adjust the compression method of the radio frequency channel mapping data or the parameters selected when generating the radio frequency channel mapping data in order to improve the performance of sensing-assisted communication.

[0210] It should be noted that Figures 5, 6, and 8 in the embodiments of this application can be implemented as individual embodiments, or any two or three embodiments can be combined as one embodiment. The following description is in conjunction with Figure 9.

[0211] Referring to Figure 9, an exemplary flowchart of a radio frequency data evaluation method provided in an embodiment of this application is shown, which may include the following operations. In this method, the first communication device in the aforementioned sensing communication node can initiate a radio frequency channel quality evaluation to the second communication device in the sensing communication node. In Figure 9, the first communication device is used as a base station and the second communication device is used as a terminal for illustration.

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

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

[0214] For example, the base station may send one or more of the following to the terminal: a scatterer quality measurement request, a radio frequency channel quality measurement request, or a radio frequency channel mapping data application request, in accordance with S501, S601, or S801.

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

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

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

[0218] For example, the terminal may send to the base station one of the following: scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality. Alternatively, the terminal may send to the base station multiple of the following: scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality. For instance, the terminal may send to the base station scatterer quality and radio frequency channel quality; the terminal may send to the base station scatterer quality and radio frequency channel mapping data application quality; the terminal may send to the base station radio frequency channel quality and radio frequency channel mapping data application quality; the terminal may send to the base station scatterer quality, radio frequency channel quality, and radio frequency channel mapping data application quality.

[0219] In one possible implementation, when the terminal sends multiple factors including scatterer quality, radio frequency channel quality, or radio frequency channel mapping data application quality to the base station, one or two of these factors satisfy a first transmission condition.

[0220] For example, when a terminal sends scatterer quality and radio frequency channel quality data to a base station, one or both of the multiple conditions must satisfy the first transmission condition. For instance, if the scatterer quality meets the first requirement, the implementation can be referenced in the embodiment shown in Figure 5. Only when the scatterer quality meets the first requirement will the terminal and the base station perform a radio frequency channel quality assessment, and only then will the terminal send the radio frequency channel quality data to the base station. If the scatterer quality does not meet the first requirement, the terminal and the base station will not perform a radio frequency channel quality assessment. The base station will re-acquire the environmental reconstruction results and re-perform a scatterer quality assessment with the terminal until the scatterer quality meets the first requirement. Only then will the terminal and the base station perform a radio frequency channel quality assessment, and only then will the terminal send the radio frequency channel quality data to the base station. In other words, if the scatterer quality does not meet the first requirement, the terminal will adjust the scatterer quality to meet the first requirement before sending the radio frequency channel quality data to the base station, as shown in the embodiment in Figure 5.

[0221] For example, when a terminal sends scatterer quality and radio frequency channel data application quality to a base station, one or both of the multiple conditions must satisfy the first transmission condition. For instance, if the scatterer quality meets the first requirement, the implementation can be referenced in the embodiment shown in Figure 5. When the scatterer quality meets the first requirement, the terminal and the base station will perform a radio frequency channel mapping data application quality assessment, and the terminal will send the radio frequency channel mapping data application quality to the base station. If the scatterer quality does not meet the first requirement, the terminal and the base station will not perform a radio frequency channel mapping data application quality assessment. The base station will re-acquire the environmental reconstruction results and re-evaluate the scatterer quality with the terminal until the scatterer quality meets the first requirement. Then, the terminal and the base station will perform a radio frequency channel mapping data application quality assessment, and the terminal can send the radio frequency channel mapping data application quality to the base station. In other words, if the scatterer quality does not meet the first requirement, the terminal will adjust the scatterer quality to meet the first requirement before sending the radio frequency channel mapping data application quality to the base station. This can be referenced in the embodiment shown in Figure 5.

[0222] For example, when a terminal sends radio frequency channel quality and radio frequency channel data application quality to a base station, one or both of the multiple conditions must satisfy the first transmission condition. For instance, if the radio frequency channel quality meets the second requirement, the implementation can be referred to the embodiment shown in Figure 6. When the radio frequency channel quality meets the second requirement, the terminal and the base station will perform a radio frequency channel mapping data application quality assessment, and the terminal will send the radio frequency channel mapping data application quality to the base station. If the scatterer quality does not meet the second requirement, the terminal and the base station will not perform a radio frequency channel mapping data application quality assessment. The base station will reacquire the radio frequency channel mapping data and re-evaluate the radio frequency channel quality with the terminal until the radio frequency channel quality meets the second requirement. Then, the terminal and the base station will perform a radio frequency channel mapping data application quality assessment, and the terminal can send the radio frequency channel mapping data application quality to the base station. In other words, if the radio frequency channel quality does not meet the second requirement, the terminal will adjust the radio frequency channel quality to meet the second requirement before sending the radio frequency channel mapping data application quality to the base station. The implementation can be referred to the embodiment shown in Figure 6.

[0223] For example, when a terminal sends scatterer quality, RF channel quality, and RF channel application quality to a base station, one or two of these conditions must satisfy the first transmission condition. For instance, the scatterer quality must satisfy the first requirement, and the RF channel direct connection must satisfy the second requirement. This can be implemented using the embodiments shown in Figures 5 and 6. Only when the scatterer quality satisfies the first requirement and the RF channel quality satisfies the second requirement will the terminal and base station evaluate the RF channel mapping data application quality, and only then will the terminal send the RF channel mapping data application quality to the base station. If the scatterer quality does not meet the first requirement, the terminal will adjust the scatterer quality to meet the first requirement before sending the RF channel quality to the base station. This can be implemented using the embodiment shown in Figure 5. Similarly, if the scatterer quality does not meet the second requirement, the terminal will adjust the RF channel quality to meet the second requirement before sending the RF channel mapping data application quality to the base station. This can be implemented using the embodiment shown in Figure 6.

[0224] In this embodiment of the application, if the application quality of the radio frequency channel mapping data does not meet the third requirement, it can be considered that the compression method of the radio frequency channel mapping data is incorrect, or the parameters selected when generating the radio frequency channel mapping data are inaccurate. In this case, the performance of the terminal performing sensing-assisted communication based on the radio frequency channel mapping data is low. Therefore, the base station can adjust the compression method of the radio frequency channel mapping data or the parameters selected when generating the radio frequency channel mapping data in order to improve the performance of sensing-assisted communication.

[0225] If the application quality of the radio frequency channel mapping data meets the third requirement, the terminal can use this radio frequency channel mapping data, such as the first radio frequency channel mapping data, for sensing-assisted communication. If the application quality of the radio frequency channel mapping data does not meet the third requirement, the accuracy of the radio frequency channel mapping data can be considered low. This problem may be due to the base station compressing the radio frequency channel mapping data before sending it to the terminal to reduce transmission pressure, and then the terminal re-unpacking it. Alternatively, it may be due to the parameters selected by the base station when generating the radio frequency channel mapping data, such as inaccurate communication links. Therefore, if the base station determines that the application quality of the radio frequency channel mapping data does not meet the third requirement, the base station can adjust the compression method of the radio frequency channel mapping data or the parameters selected when generating the radio frequency channel mapping data, and send the adjusted radio frequency channel mapping data, such as the second radio frequency channel mapping data, to the terminal. The terminal can then perform sensing-assisted communication based on the adjusted radio frequency channel mapping data.

[0226] In one possible scenario, base station processing operations can be performed by the CU (Core Unit), while base station transmit and receive operations can be performed by the DU (Distribution Unit) or RU (Receiving Unit). For example, the CU can generate a quality measurement request, which it can then send to the DU. The DU can then transmit the quality measurement request, or the DU can send the quality measurement request to the RU, which will then transmit it.

[0227] The DU can receive one or more of the following: scatterer quality, RF channel quality, or RF channel mapping data application quality, and send one or more of these qualities to the CU. The CU determines whether it is necessary to reacquire the environment reconstruction results, regenerate the RF channel mapping data, or reselect the parameters and / or compression method of the RF channel mapping data. Optionally, the RU can receive one or more of the following: scatterer quality, RF channel quality, or RF channel mapping data application quality, and send one or more of these qualities 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 transmit and receive operations can be performed by the DU or RU. For example, the CU-CP can perform the operations of the CU, the DU can perform the operations of the DU, and the RU can perform the operations of the RU.

[0229] In the O-RAN scenario, the operations performed by the 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 embodiments shown in Figure 9, the radio frequency data evaluation method provided in this application adopts a multi-layered evaluation approach, such as scatterer quality evaluation, radio frequency channel quality evaluation, and radio frequency channel mapping data application quality evaluation, which can improve the reliability and service performance of radio frequency channel mapping data. The radio frequency data evaluation method provided in this application will be described below with reference to Figure 9.

[0231] As shown in Figure 10, sensing communication nodes, such as base stations, terminals, and TRPs, can acquire environmental information through sensing and determine the environmental reconstruction result, as illustrated in the embodiments shown in Figures 4A and 4B. Base stations and terminals can perform scatterer quality assessment, as illustrated in the embodiment shown in Figure 5. If the scatterer quality meets the first requirement, the terminal and base station can generate radio frequency channel mapping data, as illustrated in 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 can perform an RF channel quality assessment, as illustrated in the embodiment shown in Figure 6. If the RF channel quality does not meet the second requirement, the base station can return to the operation of generating the RF channel mapping data. If the RF channel quality meets the second requirement, the base station can determine the parameters included in the RF channel mapping data and / or determine the RF channel mapping data compression method, and then send the RF channel mapping data to the terminal. It is understood that the RF channel mapping data can be compressed before transmission. The terminal can restore the compressed RF channel mapping data and use it for assisted communication. The terminal can determine the RF channel mapping data application quality for assisted communication and send this quality information to the base station. If the RF channel mapping data application quality meets the third requirement, the terminal continues to use the RF channel mapping data for assisted communication. If the RF channel mapping data application quality does not meet the third requirement, the base station returns to the operation of determining the parameters used when generating the RF channel mapping data and / or determining the RF channel mapping data compression method.

[0233] In another possible scenario, after generating the RF channel mapping data, the base station can determine the parameters used to generate the RF channel mapping data and / or determine the compression method of the RF channel mapping data. The base station then sends the RF channel mapping data to the terminal. It is understood that this RF channel mapping data can be sent after compression. The terminal can recover the compressed RF channel mapping data and perform sense-assisted communication based on it. The terminal can determine the application quality of the RF channel mapping data for sense-assisted communication and send the application quality information 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 sense-assisted communication. If the application quality of the RF channel mapping data does not meet the third requirement, the base station returns to the operation of determining the parameters used to generate the RF channel mapping data and / or determining the compression method of the RF channel mapping data.

[0234] In one possible implementation, RF channel mapping data can be managed through various functions and modules within an integrated sensing and communication (ISAC) system. It is understood that the ISAC system can be located in a base station, terminal, TRP, or CPE. Referring to Figure 11, the ISAC wireless data acquisition module can acquire sensing data from various sensing communication nodes and send the sensing data to the ISAC data processing module, which generates sensing results, i.e., RF channel mapping data. The ISAC data processing module can then send the RF channel mapping data to the sensing results and RF mapping data storage module for storage. The ISAC management module can send a sensing result transferring request to the sensing results and RF mapping data storage module to request the sensing results, i.e., the RF channel mapping data. The sensing results and RF mapping data storage module can then send the RF channel mapping data to the ISAC management module. The ISAC RF mapping application module can send RF channel data application requests to the ISAC management module. The ISAC management module then sends the RF channel mapping data to the ISAC RF mapping application module for sensing-assisted communication, such as energy saving, beamforming or beamforming, positioning, or multiple-input multiple-output (MIMO) data transmission.

[0235] The ISAC wireless data acquisition module can also acquire quality data, such as scatterer quality or RF channel quality, and send this data to the ISAC management module. The ISAC management module then determines whether re-sensing is required. If the ISAC management module determines that re-sensing is necessary, it can send a re-sensing request to the ISAC data processing module, which can then re-sensor or regenerate the RF channel mapping data. The ISAC management module can also send scatterer quality or RF channel quality data to the ISAC data processing module. The ISAC wireless data acquisition module can also acquire application data, such as RF channel mapping data application quality, ACK, NACK, or QoS. The ISAC wireless data acquisition module can send this application data to the ISAC RF mapping application module, which in turn can send it to the ISAC management module. The ISAC management module then determines whether the parameters and / or compression method of the RF channel mapping data need to be reselected. The ISAC management module can also send the RF channel mapping data application quality data to the ISAC data processing module.

[0236] It is understood that the names of the modules shown in Figure 11 are merely illustrative and do not constitute a limitation on the names of the modules in the ISAC system.

[0237] Based on the following embodiments, a communication device provided in this application is described. Figure 12 is a schematic block diagram of a communication device 1200 provided in an embodiment of this application. This communication device 1200 can correspondingly implement the functions or steps implemented by the first or second communication device in the various method embodiments described above. The communication device may include a processing unit 1210 and a transceiver unit 1220.
