Summary of the invention

[0004] The present application provides a communication method and a communication device, which can ensure that the transmission of radio frequency channel mapping data is more flexible, thereby ensuring that the radio frequency channel mapping data is transmitted efficiently.

[0008] In an embodiment of the present application, the terminal device can send a first indication information to the network device, which can facilitate the network device to send the first data information to the terminal device after learning that the terminal device has the ability to expand the RF channel mapping data. When the first data information includes the first RF channel mapping data, the terminal device can use the first RF channel mapping data for communication or positioning. When the first data information includes: scatterer information and / or virtual transmission point information, the terminal device can determine the second RF channel mapping data based on the above information, and use the second RF channel mapping data for positioning or communication. When the first data information includes: the first RF channel mapping data, the scatterer information and the virtual transmission point information, the terminal device can determine the second RF channel mapping data based on the scatterer information and the virtual transmission point information, and use the first RF channel mapping data and the second RF channel mapping data for positioning or communication. In this way, the transmission of the RF channel mapping data can be guaranteed to be more flexible, and by introducing the scatterer information and / or the virtual transmission point information, the compression quality and size of the first data information can be guaranteed, thereby ensuring efficient transmission of the RF channel mapping data.

[0085] In order to facilitate understanding of the embodiments of the present application, first, a brief introduction is given to the concepts and technologies involved in the embodiments of the application.

[0086] (1) Perception, also known as wireless perception, refers to the emission of electromagnetic energy into space. By receiving the radio waves reflected by the objects in the space, the information of the object can be calculated. For example, parameters such as position, direction, height, speed, size, trajectory, etc., and the internal and external shape and structure of the object can be detected. 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 can be used as an important alternative technology in security inspection, hidden object detection, environmental reconstruction and monitoring due to its penetration and safety.

[0087] (2) Sensing reference unit (SRU): describes the situation where there is correlation or cooperation between different scattering points when the signal is scattered or reflected. In communication systems, correlated scatterers may also affect the characteristics of the channel. Therefore, understanding the correlation of signals between scatterers is very important for optimizing communication links and system design.

[0088] (3) Virtual transmit point (VTP): A wireless network may include multiple transmit points (TPs) that span a coverage area and may be divided into one or more coordination sets, which may be referred to as VTPs.

[0089] (4) RF channel mapping map, RF channel mapping data

[0090] In a communication system, wireless sensing technology can be used to obtain environmental information to assist in channel prediction, positioning, beamforming, etc., thereby improving the quality of communication services. Among them, the process of using wireless sensing technology to predict and form a radio frequency channel mapping map is called radio frequency mapping (RF mapping). The map obtained by RF mapping is called a radio frequency channel map. The data corresponding to the radio frequency channel map is called radio frequency channel data.

[0091] In the present application, the radio frequency channel map may correspond to a certain geographical area, and is used to indicate the geographical location and size of multiple areas divided in the geographical area. The geographical area may be an area of ​​a certain range in the real physical world. For example, the geographical area may be characterized by longitude, latitude and altitude. For example, the starting point is recorded as (x0, y0, z0), and the outdoor scene of 100m×100m is based on the starting point. The multiple areas may be areas obtained by dividing the geographical area in a certain way. For example, the above-mentioned 100m×100m geographical area is divided in a 1m×1m manner to obtain 100×100 areas. Each area is 1m×1m.

[0092] It should be understood 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) can have at least one of the following attributes: shape, size, area, geographical location, etc. In this application, different areas have the same shape, outline, size, radius, and area. Different areas have different geographical locations. There is no overlap between different areas.

[0093] In a possible implementation, the shape of the area involved in the radio frequency channel map may be a square, or other shapes, such as a rectangle, a trapezoid, a triangle, etc. Alternatively, the shape of the area may also be an irregular shape, which is not limited.

[0094] Exemplarily, the shape of the area may be defined by a protocol or may be defined by a network device. The shapes of the areas defined by different network devices may be the same or different. The same network device may also define multiple shapes of areas. Similarly, the size, radius, and area of ​​the area may be defined by a protocol or may be defined by a network device. The size, radius, and area of ​​the areas defined by different network devices may be the same or different. The same network device may also define multiple area sizes, multiple area radii, or multiple area areas.

[0095] In a possible implementation, multiple regions may be indexed (eg, numbered) to identify different regions.

[0096] In the present application, the radio frequency channel map may include a plurality of grids, and the plurality of grids correspond one-to-one to a plurality of areas.

[0097] It should be understood that in the present application, the grid involved in the RF channel map may have at least one of the following attributes: shape, size, area, etc. Among them, the shape of the grid may be consistent with the shape of the area corresponding to the grid. The size of the grid is in a certain ratio to the size of the area corresponding to the grid. The area of ​​the grid is in a certain ratio to the area size of the area corresponding to the grid. Among them, the size of the grid may also have other descriptions, such as resolution.

[0098] The following introduces the technical problems to be solved by this application and the technical solutions adopted.

[0099] With the continuous development of wireless sensing technology, wireless sensing technology has a wide range of applications in various fields. Wireless sensing technology can refer to the device emitting electromagnetic energy into space. With the help of the radio waves reflected by objects in space, the processing unit of the device (for example, terminal device or network device) can calculate the information of the object (for example, the object's position, direction, height, speed, size and trajectory parameters) and detect the external shape and structure of the object to better understand the physical world where the device is located.

[0100] By applying wireless sensing technology in the field of communication, the electromagnetic signals used for communication and the electromagnetic signals used for perception can be integrated to form a communication and perception integrated system. In the communication and perception integrated system, the network device and the terminal device are the main devices for reconstructing the virtual environment. The quality of perception by the network device and the terminal device can be related to factors such as synaesthesia resources, space, time, frequency band, power consumption and site. Among them, space can include the number of beams, which can affect the perception angle range. Time can include the perception symbol length, which can affect the perception azimuth accuracy. The frequency band can include the perception bandwidth, which can affect the perception distance accuracy. Power consumption can include the perception signal power, which can affect the perception distance range. The site can refer to the type of equipment, for example, a network device, a terminal device or a wireless terminal access equipment (customer premises equipment, CPE), etc. The site can include the communication capacity, which can affect the perception fusion accuracy.

[0101] In the perception and communication integrated system, according to the co-station or easy-station situation of the transmitting and receiving ends of the perception signal, it can be divided into single-base (monostatic), dual-base (bi-static) and multi-base (multi-static) communication perception integrated systems, among which the multi-base communication perception integrated system can refer to a hybrid system composed of a single base and a dual base. It can be understood that the single-base communication perception integrated system can also be called single-station perception, that is, perception is performed through one site. Similarly, the multi-base communication perception integrated system can also be called multi-station perception, that is, perception is performed through two or more sites. Similarly, the multi-base communication perception integrated system can be called multi-station perception.

[0102] Below Figure 1 and Figure 2 Take the single-base and dual-base communication perception integrated system as an example.

[0103] like Figure 1 As shown in the figure, the transmitter and receiver of the single-base communication perception integrated system can be in the same position (for example, located inside the same device), and the perception signal can use data static load, so that the transmitter and receiver do not consume communication resources. At the same time, since the perception signal is sent and received from the same source, there is no influence of non-ideal factors such as synchronization in the single-base communication perception integrated system, and its perception algorithm complexity and estimation accuracy are better. In addition, since the perception signal of the single-base communication perception integrated system adopts a self-transmitting and self-receiving mode, the signal angle range that can be detected is strongly related to the environmental incident angle. The reflected signal of the object decays rapidly as the incident angle increases. That is, the viewing angle range of the single-base environment reconstruction is greatly affected by the material and placement angle of the target object. In the single-base communication perception integrated system, most of the components of the echo signal are single bounces, which meet the radar assumption. When solving the environmental space, the problem of ill-conditioned equations is small, and the accuracy of solving the spatial environment is high.

[0104] in, Figure 1 The scenario shown in (a) is an uplink scenario, that is, the UE may include a receiver and a transmitter, and after sensing the target, the UE may exchange information with the BS; Figure 1 The scenario shown in (b) is a downlink scenario, that is, the BS may include a receiver and a transmitter, and the BS may interact with the UE after sensing the target.

[0105] like Figure 2 As shown, the transmitter and receiver of the dual-base communication perception integration system are in different locations (for example, in the UE and the base station, respectively), and the perception signal can use a dedicated pilot or a known signal, which requires the perception function to consume communication resources. At the same time, since the perception signal is sent and received from different sources, it may be affected by non-ideal factors such as synchronization and phase noise in the dual-base communication perception integration system, and its perception algorithm complexity and estimation accuracy are poor, requiring a more complex calibration algorithm to process. In addition, in the dual-base perception communication integration architecture, since the echo signal has rich components, the echo signal has a large number of multiple reflection paths or the power of the reflection path is high. In urban spaces where scattering is prone to occur, a large number of multiple reflection paths may introduce ill-conditioned equations, resulting in shadow space and erroneous solutions when solving the virtual environment, which has a great impact on the accuracy of perception.

[0106] in, Figure 2The scenario shown in (a) is an uplink scenario, the UE may include a transmitter, and the BS may include a receiver, that is, the UE may send a perception signal, and the BS may receive the perception signal to achieve perception of the target; Figure 2 The scenario shown in (b) is a downlink scenario, the BS may include a transmitter, and the UE may include a receiver, that is, the BS may send a perception signal, and the UE receives the perception signal to achieve perception of the target.

[0107] Whether in a single-base communication perception integrated system or a dual-base communication perception integrated system, both involve interaction between the terminal device and the base station. Currently, the base station can use image compression to send RF channel mapping data to the terminal device. Such data compression method cannot guarantee the quality and size of data compression, making the efficiency of transmitting RF channel mapping data low.

[0108] The embodiments of the present application provide a communication method and a communication device, which can ensure that the transmission of radio frequency channel mapping data is more flexible, thereby ensuring that the radio frequency channel mapping data is efficiently transmitted.

[0109] It should be understood that in the embodiments of the present application, BS and network device may refer to the same concept and may be used interchangeably.

[0110] Below Figure 3 Take the following as an example to introduce how to obtain and transmit RF channel mapping data.

[0111] exist Figure 3 In (a), the dotted line may represent a road. Figure 3 In the physical environment shown in (a), there may be multiple sensing communication nodes, such as base stations, terminal devices, transmission and receiving points (TRPs) or CPEs. The sensing communication nodes can emit electromagnetic waves or radar signals to obtain the reconstructed map, such as Figure 3 As shown in (b) in the figure. For example, the sensing communication node can transmit electromagnetic waves or radar signals and receive echo signals, so as to obtain scatterer information in the physical environment. In one possible scenario, each sensing communication node can interact with the acquired scatterer information, so as to obtain a higher-precision environment reconstruction result in a larger range. Figure 3 As shown in (b), any one of the plurality of sensing communication nodes may divide the physical environment map into a plurality of grids, and each grid is regarded as a location. For the convenience of description, any one of the plurality of sensing communication nodes is referred to as a target sensing communication node.

[0112] For example, the target-aware communication node can divide the physical environment map into multiple rectangular areas or grids, such as Figure 3 As shown in (c) in the figure. For another example, the target-aware communication node may divide the physical environment map into different circular areas (not shown in the figure). For another example, the target-aware communication node may divide the physical environment map into different hexagonal areas or so-called cellular areas (not shown in the figure), etc., which are not specifically limited in this application. It is understandable that when the target-aware communication node divides the physical environment map into multiple areas, the resolution of the area may be predefined or preconfigured by the protocol, such as dividing the physical environment map into multiple areas at a resolution of 5m, 10m, etc., which is not specifically limited in this application. This article takes the example of the target-aware communication node dividing the physical environment map into multiple grids for explanation.

[0113] The target-aware communication node can assume that there is a terminal device in each location and simulate the device transmission path from the base station to the terminal device at each location, such as Figure 3 As shown in (c) in FIG. 1 . It is understandable that the transmission path may include a direct transmission path from the base station to the terminal device, or may include a transmission path from the base station to the terminal device after being reflected by a scatterer. For example, the target sensing communication node may use a mirror line of sight tracking algorithm to obtain the transmission path from the base station to the terminal device at each position. The target sensing communication node may calculate the channel state prediction value of each position through the simulated transmission path, such as Figure 3 As shown in (d) in the figure. Exemplarily, the target-aware communication node can calculate the channel state prediction value of the transmission path from the base station through the environment to the terminal devices at various locations through ray tracing tools, electromagnetic calculation tools, or simple simulation tools based on mirror reflection. In addition, the target-aware communication node can obtain the scatterer information associated with each location, that is, the information of the scatterer passed by the terminal devices at various locations from the base station. In this way, the RF channel mapping data can be obtained.

[0114] It should be noted that the above-mentioned method of obtaining radio frequency channel mapping data is only shown as an example and does not constitute a limitation on the method of obtaining radio frequency channel mapping data.

[0115] The content of the RF channel mapping data in the embodiment of the present application can be referred to as shown in Table 1. It can be understood that the RF channel mapping data can be stored in an entity with a perception function or a perception fusion function, such as a SMF entity or a location management function (LMF) entity in a TRP, a terminal device, a base station or a core network device. That is to say, after obtaining the RF channel mapping data, the above-mentioned target perception communication node can send the RF channel mapping data to the SMF entity or LMF entity in the TRP, the terminal device, the base station or the core network device.

[0116] Table 1: An example of RF channel mapping data

[0117]

[0118] As shown in Table 1, the radio frequency channel mapping data may include one or more of configuration information of the measurement signal, grid setting information, location information, channel state prediction value, associated scatterer or scatterer group, and associated perceived quality.

[0119] 1. The configuration information of the measurement signal may include one or more of the antenna port number for transmitting and receiving signals, precoding information, subcarrier configuration, etc.

[0120] It can be understood that the configuration information of the above-mentioned measurement signal can be the configuration information used by the sensing communication node to send electromagnetic waves when obtaining the reconstructed map, such as the transceiver antenna port number, precoding information and subcarrier configuration.

[0121] 2. Location information, indicating the geographic location. The location information may be indicated by a relative location, such as a distance or angle relative to a certain base station, or an absolute location, such as latitude and longitude information. Alternatively, the location information may be indicated by a grid number. In Table 1, the subscript i may be understood as a grid number.

[0122] 3. Grid setting information, indicating the starting position of the grid and / or the resolution of the grid.

[0123] The starting position of the grid may indicate the starting position when dividing the grid, and may be indicated by a relative position or an absolute position. The resolution of the grid may indicate the scale used when dividing the grid. It is understandable that the resolution of the grid may not be indicated, and a default resolution may be used.

[0124] 4. The channel state prediction value can be indicated by multipath information, such as power delay profile (PDP), channel impulse response (CIR), etc. The channel state prediction value is calculated by the transmission path from the target sensing communication node to the terminal device at each location through the base station.

[0125] 5. Associated scatterer information or scatterer group information, information about the scatterer or scatterer group associated with the transmission path when estimating the channel state prediction value of the grid. In one possible scenario, the scatterer information or scatterer group information may include one or more of the scatterer identification and the scatterer location information. The location information of the scatterer may be indicated by the coordinate information of the grid or by the absolute position or relative position. Optionally, the scatterer information or scatterer group information may also include acquisition time information, such as a timestamp, which represents Figure 3 (b) The sensing communication node senses the scatterer or scatterer group at this timestamp.

[0126] 6. Associated perceived quality, perceived quality corresponding to the grid, equivalent perceived accuracy service quality. Optionally, the perceived quality corresponding to the grid may have an initial value, which may be set to a preset minimum value, or may be determined based on the acquisition time information of the scatterer information or the scatterer group information. For example, the greater the time difference between the acquisition time information and the current time, the lower the initial value, and the smaller the time difference between the acquisition time information and the current time, the higher the initial value. The associated perceived quality may be updated in subsequent measurements.

[0127] Combine the following Figures 4 to 8 The communication method provided in the embodiment of the present application is introduced.

[0128] Figure 4 A communication method provided in an embodiment of the present application, method 400 can be applied to Figure 2 or Figure 3 In the communication-awareness integrated system shown, method 400 may include steps S401 to S407.

[0129] S401: The terminal device sends first request information to the network device.

[0130] Exemplarily, the first request information is used to request the network device to send at least one of the following to the terminal device: first RF channel mapping data, scatterer information and virtual transmission point information, and the scatterer information and / or virtual transmission point information are used by the terminal device to determine the second RF channel mapping data.

[0131] Optionally, the first RF channel mapping data and the second RF channel mapping data may be composed of elements R i composition, which shows the grid (x i ,y i ,z i ) is the multipath component predicted by the environment, where i is a positive integer.

[0132] Optionally, the contents of the first RF channel mapping data and the second RF channel mapping data may be as shown in Table 1. For example, the first RF channel mapping data and the second RF channel mapping data may include at least one of the following: configuration information of the measurement signal, geographic location information, area starting position, channel state prediction value or perceived quality information.

[0133] In one implementation, the first RF channel mapping data and the second RF channel mapping data correspond to different geographical areas.

[0134] Optionally, the different geographical areas corresponding to the first RF channel mapping data and the second RF channel mapping data can be understood as: the grid areas corresponding to the first RF channel mapping data and the second RF channel mapping data are different. Figure 5 As shown, the radio frequency channel map is divided into a plurality of grid areas, the grid area corresponding to the first radio frequency channel mapping data is the area occupied by elements R1 to R6, and the grid area corresponding to the second radio frequency channel mapping data is the area occupied by elements R7 to R8. 12 The area occupied by Figure 5 It can be seen that the positions (coordinates) of the grid areas corresponding to the first RF channel mapping data and the second RF channel mapping data are different.

[0135] S402: The network device sends second request information to the first network element according to the first request information.

[0136] Exemplarily, the second request information is used to request the first network element to determine at least one of the following: first radio frequency channel mapping data, scatterer information, or the virtual transmission point information. In this way, a multi-level feedback mechanism is created so that the network device can determine the response result to the first request information based on the response result of the first network element to the second request information to meet the needs of the terminal device.

[0137] Optionally, the first network element may be an SMF.

[0138] Optionally, the scatterer information can be used to indicate N independent scatterer information, where N is a positive integer. Further, the scatterer information can be used to indicate at least one of the following contents corresponding to the N scatterer information: site information (for example, perception link number, sending or receiving site number, site configuration, etc.), scatterer number, coordinates (x, y, z), angle (for example, arrival angle and / or emission angle of the perception signal), reliability of the measured scatterer, and received power and speed of the perception signal.

[0139] Optionally, the above-mentioned scatterer information can be used to indicate P independent scatterer group information, each scatterer group can be composed of K scatterers with high parameter correlation, P and K are positive integers, for example, when the correlation (for example, difference, covariance or Euclidean distance) between scatterer 1 and scatterer 2 is greater than a threshold value, scatterer 1 and scatterer 2 can be considered to belong to the same scatterer group. Further, the scatterer information can be used to indicate at least one of the following contents corresponding to the P scatterer group information: site information, scatterer group number, center position coordinates (x, y, z), scatterer group size, normal direction, vertex center position coordinates (x, y, z), attributes, classification or speed. Among them, for a scatterer group, there is only one center position, and there may be multiple vertex center positions. The approximate outline of the scatterer group can be determined by multiple vertex positions.

[0140] S403: The first network element determines at least one of the following contents according to the second request information: first radio frequency channel mapping data, scatterer information, or virtual transmission point information.

[0141] S404: The first network element sends second response information to the network device.

[0142] Exemplarily, the second response information includes at least one of the following: first radio frequency channel mapping data, scatterer information, or virtual transmission point information.

[0143] S405: The terminal device sends first indication information to the network device.

[0144] Exemplarily, the first indication information is used to indicate that the terminal device has the capability of extending the RF channel mapping data. The capability of the terminal device to extend the RF channel mapping data includes: the terminal device determines the second RF channel mapping data based on the scatterer information and / or the virtual transmission point information.

[0145] Optionally, step S405 and step S401 are performed together, that is, the terminal device may send the first request information and the first indication information in step S401, and in this case, step S405 may no longer be performed.

[0146] Optionally, the terminal device may send first indication information to the network device when receiving the first response information sent by the network device, and the first response information is used to indicate that the network device accepts the first request information. In this way, by using the first response information, it is possible to avoid the terminal device still reporting the first indication information to the network device when the network device rejects the first request information, thereby avoiding the waste of communication resources.

[0147] Optionally, the first indication information can also be used to indicate at least one of the following: a channel state prediction value corresponding to the first RF channel mapping data and a channel state prediction value corresponding to the second RF channel mapping data, an area starting position corresponding to the first RF channel mapping data and an area starting position corresponding to the second RF channel mapping data, an area position interval between the first RF channel mapping data and the second RF channel mapping data, or available coordinates corresponding to the second RF channel mapping data.

[0148] Among them, the channel state prediction value can also be used to indicate the data type of the RF channel mapping data, which can specifically include at least one of the following information: angles delay spread (ADP), PDP, CIR, channel state information (SCI) information and pilot measurement results. Further, SCI can be, for example: CSI-RS resource indicator (CRI), rank indicator (RI), channel quality indicator (CQI), precoding matrix indicator (PMI) or layer indicator (LI); the regional starting position can refer to the starting position corresponding to the grid number; the regional position interval between the first RF channel mapping data and the second RF channel mapping data can refer to the position interval between the first RF channel mapping data and the second RF channel mapping data on the grid area; the available coordinates corresponding to the second RF channel mapping data can refer to the available grid coordinates or grid codes.

[0149] For example, Figure 5 As shown, the first indication information can also be used to indicate the starting position of element R1 in the first RF channel mapping data in the grid (first row and first column) and the starting position of element R7 in the second RF channel mapping data in the grid (third row and fourth column).

[0150] For example, Figure 5 As shown, the first indication information may also indicate that the position interval between the first RF channel mapping data and the second RF channel mapping data in the grid is 15.

[0151] For example, Figure 5 As shown, the first indication information may also indicate that the available coordinates corresponding to the second RF channel mapping data are the 4th to 9th columns in the third row in the grid.

[0152] S406: The network device determines the first data information according to the second response information.

[0153] In a possible implementation manner, the content indicated by the first data information and the content of the second response information may be completely identical, that is, at this time the network device plays a role of information forwarding.

[0154] For example, when the second response information includes: first radio frequency channel mapping data, the first data information may include: first radio frequency channel mapping data.

[0155] For another example, when the second response information includes: scatterer information and / or virtual transmission point information, the first data information may include: scatterer information and / or virtual transmission point information.

[0156] For another example, when the second response information includes: first RF channel mapping data, and the second response information also includes scatterer information and / or virtual transmission point information, the first data information may include: first RF channel mapping data, and scatterer information and / or virtual transmission point information.

[0157] In a possible implementation, the content indicated by the first data information and the content of the second response information may be different, that is, the network device may independently determine the content of the first data information. This helps to provide more accurate, efficient and personalized communication services to the terminal device, while helping to save network resources.

[0158] For example, when the second response information includes: scatterer information and / or virtual transmission point information, the first data information may include: first RF channel mapping data, as well as scatterer information and / or virtual transmission point information; that is, the first RF channel mapping data is determined by the network device at this time.

[0159] For another example, when the second response information includes: first RF channel mapping data, and the second response information also includes scatterer information and / or virtual transmission point information, the first data information may only include: scatterer information and / or virtual transmission point information; that is, at this time the network device can independently decide not to send the first RF channel mapping data to the terminal device.

[0160] S407: The network device sends first data information to the terminal device according to the first indication information.

[0161] After receiving the first data information, the terminal device may perform different processing according to the content of the first data information.

[0162] In one implementation, when the first data information includes first radio frequency channel mapping data, the terminal device may use the first radio frequency channel mapping data for communication or positioning.

[0163] In one implementation, when the first data information includes: scatterer information and / or virtual transmission point information, the terminal device can determine the second RF channel mapping data according to the above information, and use the second RF channel mapping data for communication or positioning.

[0164] In one implementation, when the first data information includes first RF channel mapping data, and the first data information also includes: scatterer information and / or virtual transmission point information, the terminal device can determine the second RF channel mapping data based on the scatterer information and / or virtual transmission point information, and use the first RF channel mapping data and the second RF channel mapping data for communication or positioning.

[0165] In an embodiment of the present application, the terminal device can send a first indication information to the network device, which can facilitate the network device to send the first data information to the terminal device after learning that the terminal device has the ability to expand the RF channel mapping data. When the first data information includes the first RF channel mapping data, the terminal device can use the first RF channel mapping data for communication or positioning. When the first data information includes: scatterer information and / or virtual transmission point information, the terminal device can determine the second RF channel mapping data based on the above information, and use the second RF channel mapping data for positioning or communication. When the first data information includes: the first RF channel mapping data, the scatterer information and the virtual transmission point information, the terminal device can determine the second RF channel mapping data based on the scatterer information and the virtual transmission point information, and use the first RF channel mapping data and the second RF channel mapping data for positioning or communication. In this way, the transmission of the RF channel mapping data can be guaranteed to be more flexible, and by introducing the scatterer information and / or the virtual transmission point information, the compression quality and size of the first data information can be guaranteed, thereby ensuring efficient transmission of the RF channel mapping data.

[0166] It should be understood that in the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem including the network device functions. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device including the terminal device functions.

[0194] In a possible implementation, when the communication system includes multiple terminal devices, and the multiple terminal devices have the ability to expand the radio frequency channel mapping data, each terminal device can self-expand and generate corresponding second radio frequency channel mapping data according to the SRU and / or VTP information sent by the network device.

At this time, the terminal device may only use the first RF channel mapping data for communication or positioning.

[0196] In a possible implementation, considering the balance between computational overhead and transmission overhead, the network device may transmit the R corresponding to the first RF channel mapping data in a partial grid area. a, transmit the SRU information and / or VTP information in another part of the grid area to ensure that the terminal device can generate the R corresponding to the second RF channel mapping data based on the SRU information and / or VTP information extension in another part of the grid area. b , where a and b are both positive integers, and the values ​​of a and b are different.
