Description

Communication methods and related devices

[0001] This application claims priority to Chinese Patent Application No. 202411577843.8, filed on November 5, 2024, entitled "Communication Method and Related Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0003] In communication systems, when multiple sensing nodes exist, they can be combined to improve sensing accuracy. Currently, for a given sensing area, multiple sensing nodes obtain corresponding sensing data. Then, the sensing network element averages the sensing data from multiple nodes to obtain merged sensing data, which is used to achieve sensing of the area. However, different sensing nodes have different sensing resolutions; in other words, different sensing nodes have different sensing capabilities. Furthermore, the sensing data contains noise, meaning each sensing data point has a corresponding signal-to-noise ratio (SNR). The SNR of the sensing data is related to the transmission power of the sensing signals sent by the sensing nodes.

[0004] Therefore, how to configure the transmission power of sensing signals to improve sensing performance for sensing nodes with different sensing capabilities is a question worth considering. Summary of the Invention

[0005] This application provides a communication method and related apparatus for a first communication device to receive first information from a second communication device. This is beneficial for improving sensing performance, or avoiding the waste of sensing resources.

[0006] This application provides a communication method, which is applied to a first communication device, or to a component (e.g., a processor, apparatus, circuit, chip, or chip system) within the first communication device, or to a logic module or software capable of implementing all or part of the functions of the first communication device; this application does not limit the scope of the method. The following describes the solution of this application using a first communication device as an example. The method includes: the first communication device receiving first information from a second communication device, the first information including sensing resolution information supported by the second communication device; the first communication device sending second information to the second communication device, the second information being determined based on the first information, the second information used to determine the transmission power of the second communication device, the transmission power of the second communication device being used to transmit sensing signals, or the second information used to indicate that the second communication device does not participate in sensing.

[0007] In the above technical solution, the first communication device receives first information from the second communication device. The first information includes sensing resolution information supported by the second communication device. The first communication device determines second information based on the first information and sends the second information to the second communication device. The second information is used to determine the transmission power of the second communication device. This allows for configuring the second communication device with an appropriate transmission power, which is beneficial for improving sensing performance. For example, the first communication device allocates appropriate transmission power to each sensing node based on the sensing resolution information supported by each sensing node. This helps optimize the signal-to-noise ratio of the merged sensing data (obtained by merging sensing data from multiple sensing nodes), thereby improving sensing performance. Alternatively, the second information can be used to instruct the second communication device not to participate in sensing, avoiding waste of sensing resources.

[0008] Based on the first aspect, in one possible implementation, the perceived resolution information includes at least one of the following: a first resolution vector, a second resolution vector, or a third resolution vector; wherein the first resolution vector is used to characterize the range resolution supported by the second communication device, the second resolution vector is used to characterize the azimuth resolution supported by the second communication device, and the third resolution vector is used to characterize the pitch resolution supported by the second communication device. In this implementation, the perceived resolution information supported by the second communication device is characterized by the resolution vector. This is beneficial for the first communication device to measure the resolution capability of the second communication device through the resolution vector and to allocate appropriate transmission power to the second communication device.

[0009] Based on the first aspect, in one possible implementation, the first information further includes at least one of the following: the path loss corresponding to the second communication device, or the maximum transmission power information supported by the second communication device. Enabling the first communication device to further combine the path loss and maximum transmission power information to reasonably allocate transmission power is beneficial in scenarios involving multiple sensing nodes, maximizing the signal-to-noise ratio of the sensing data, and improving sensing performance.

This implementation provides another form of the second information, facilitating the second communication device to determine its own transmission power by combining the second information. This is beneficial for scenarios where the target to be sensed is moving, where the second communication device combines the second information and the path loss corresponding to the second communication device to determine an appropriate transmission power. It also helps improve sensing performance.

Optionally, the second weighting coefficient is the product of the square of the first weighting coefficient and the reference power. This implementation provides another form of the second information, facilitating the second communication device to determine its own transmission power in conjunction with the second information. This is beneficial for scenarios where the target to be sensed is moving, where the second communication device combines the second information and the path loss corresponding to the second communication device to determine an appropriate transmission power. Enriching the implementation of the scheme also helps to improve sensing performance.

In a sensing scenario where the second communication device acts as the transmitter of the sensing signal and the third communication device acts as the receiver of the sensing signal, the first communication device should also combine the location information of the second and third communication devices to determine the distance resolution, and then combine the distance resolution to determine the second information.

[0107] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0108] The term "and / or" appearing in this application can describe the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "or" relationship.

[0109] Wireless communication sensing fusion can be widely applied in typical scenarios such as intelligent transportation, intelligent low-altitude airspace, and intelligent networks. It achieves unified design of communication and sensing functions through joint signal design and hardware sharing. Sensing in wireless communication sensing fusion can be understood as wireless sensing technology based on a communication system. For example, a base station transmits wireless signals to a target object and receives the echo signals reflected by the object. The base station analyzes the echo signals to obtain corresponding sensing data, such as the number, location, speed, and identification of the target object.

[0110] Currently, sensing methods mainly include base station-side sensing, terminal device-assisted sensing, and terminal device-side sensing, which can be further divided into six sensing modes. These six sensing modes are described below with reference to Figures 1a to 1f.

[0111] Figure 1a is a schematic diagram of a scenario for base station-side sensing according to an embodiment of this application. As shown in Figure 1a, the access network device transmits a sensing signal. This sensing signal is reflected by a target object to obtain a reflected signal (or echo signal). The access network device receives the reflected signal and measures it to obtain sensing data. The access network device can send this sensing data to the sensing management function.

[0112] Figure 1b is a schematic diagram of another scenario for base station-side sensing according to an embodiment of this application. As shown in Figure 1b, access network device #1 transmits a sensing signal. This sensing signal is reflected by the target object to obtain a reflected signal. Access network device #2 receives the reflected signal and measures it to obtain sensing data. Access network device #2 can send this sensing data to the sensing management function.

[0113] Figure 1c is a schematic diagram of a scenario for terminal device-assisted sensing according to an embodiment of this application. As shown in Figure 1c, the access network device transmits a sensing signal. This sensing signal is reflected by a target object to obtain a reflected signal. The terminal device receives the reflected signal and measures it to obtain sensing data. The terminal device can report this sensing data to the sensing management function.

[0114] Figure 1d is a schematic diagram of another scenario for terminal device-assisted sensing according to an embodiment of this application. As shown in Figure 1d, the terminal device transmits a sensing signal. This sensing signal is reflected by the target object to obtain a reflected signal. The access network device receives the reflected signal and measures the reflected signal to obtain sensing data. The access network device can send this sensing data to the sensing management function.

[0115] Figure 1e is a schematic diagram of a scenario for sensing on the terminal device side according to an embodiment of this application. As shown in Figure 1e, the terminal device emits a sensing signal. This sensing signal is reflected by the target object to obtain a reflected signal. The terminal device receives the reflected signal and measures it to obtain sensing data. The terminal device can report this sensing data to the sensing management function.

[0116] Figure 1f is a schematic diagram of another scenario for sensing on the terminal device side according to an embodiment of this application. As shown in Figure 1f, terminal device #1 transmits a sensing signal. This sensing signal is reflected by the target object to obtain a reflected signal. Terminal device #2 receives the reflected signal and measures the reflected signal to obtain sensing data. Terminal device #2 can report the sensing data to the sensing management function.

[0117] This application applies to the perception scenarios shown in Figures 1a to 1f above. It should be noted that Figures 1a to 1f are merely example scenarios, and this application does not limit the perception scenarios.

[0118] When a communication system has multiple sensing nodes, they can work together to improve sensing performance. For a given sensing area, multiple sensing nodes obtain corresponding sensing data. Then, the sensing management function averages the sensing data from multiple nodes to obtain merged sensing data, which is used to achieve sensing of the sensing area. However, different sensing nodes have different sensing resolutions; in other words, different sensing nodes have different sensing capabilities. For example, as shown in Figure 2, for the sensing area, sensing nodes 1 and 2 are allocated larger bandwidths for transmitting sensing signals, thus providing strong distance resolution. However, sensing nodes 1 and 2 are relatively far from the sensing area, resulting in weaker lateral resolution. Sensing node 3, on the other hand, is closer to the sensing area, thus exhibiting strong lateral resolution. Since sensing data contains noise, each sensing data point has a corresponding signal-to-noise ratio (SNR). Maximizing the SNR of the sensing data from multiple sensing nodes aims to improve sensing accuracy and thus enhance sensing performance. The SNR of the sensing data is related to the transmission power of the sensing signals transmitted by the sensing nodes. Therefore, how to configure the transmission power of sensing signals to improve sensing performance for sensing nodes with different sensing capabilities is a question worth considering. Please refer to the relevant descriptions in the embodiments below for details.

[0119] The technical solution of this application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP). For example, 4th generation (4G) communication systems, 5th generation (5G) communication systems, and future communication systems. For instance, 4th generation communication systems may include Long Term Evolution (LTE) communication systems, LTE Frequency Division Duplex (FDD) systems, or LTE Time Division Duplex (TDD) systems. 5th generation communication systems may include New Radio (NR) communication systems. The technical solution of this application can also be applied to Wireless Fidelity (WiFi) systems, communication systems supporting the convergence of multiple wireless technologies, device-to-device (D2D) systems, Internet of Things (IoT) communication systems, Industrial Internet (IIoT) communication systems, Vehicle-to-Everything (V2X) communication systems, or satellite communication systems, etc.

[0120] The following describes a possible communication system applicable to this application, with reference to Figure 3A.

[0121] Figure 3A is a schematic diagram of a communication system according to an embodiment of this application. Referring to Figure 3A, the communication system includes sensing node 1, sensing node 2, sensing node 3, and a sensing management function. Sensing node 1, sensing node 2, and sensing node 3 jointly sense the sensing area and report the obtained sensing data to the sensing management function. The sensing management function can fuse the sensing data reported by sensing node 1, sensing node 2, and sensing node 3 respectively, and realize the sensing of the sensing area through the fused sensing data.

[0122] It should be noted that the communication system shown in Figure 3A above is merely an example. In practical applications, the communication system provided in this application includes multiple sensing nodes and sensing management functions.

[0123] It should be noted that the sensing node in the communication system shown in Figure 3A above is an example of an access network device using a self-transmitting and self-receiving sensing mode. In practical applications, the sensing node can also be a terminal device using a self-transmitting and self-receiving sensing mode. Alternatively, the sensing node can include both access network devices and terminal devices, with the access network devices and terminal devices performing the sensing process. This application does not impose any specific limitations on this.

[0124] The following describes the terminal equipment, access network equipment, and sensing management functions involved in this application.

[0125] Terminal equipment, also known as UE, mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises equipment (CPE), etc., is a device that includes wireless communication functions (providing voice / data connectivity to users) and / or sensing functions.

For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in vehicle-to-everything (V2X) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, or set-top boxes. The terminal device can also be a device or module that is connected to the communication system shown above and has corresponding communication and / or sensing functions; or the terminal device is a device with a communication function module and / or a sensing function module. The terminal device is usually equipped with a communication module, circuit or chip that performs the corresponding communication and / or sensing functions, and the terminal device is also equipped with program instructions for performing the corresponding communication and / or sensing functions.

[0126] Optionally, the terminal device may also include a module for implementing sensing functions (hereinafter referred to as the sensing module). This module can be a new module or an existing module with functional (e.g., sensing function) extensions. For example, the communication module may be extended so that it can process both communication signals and sensing signals. Optionally, a module that has both communication and sensing functions can be called a communication-sensing integrated module. The sensing module is used to support and / or implement the sensing function. Optionally, the sensing module can also be called a sensing function processor, etc., which is not limited in this application.

[0127] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, control unit, or circuit in the device or apparatus shown above; this application does not impose any specific limitation. It should also be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or to the chip, module, control unit, or circuit within the terminal device that performs the method provided in this application; this application does not impose any specific limitation.

[0128] Access network equipment is a device deployed in a radio access network that provides wireless communication, sensing, and / or integrated communication and sensing functions for terminal devices. Access network equipment can also be referred to as an access network (RAN) entity, access node, network node, or communication device, etc.

[0129] Specifically, access network equipment can be access network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, fourth-generation (4G) mobile communication systems, 5G mobile communication systems, or future mobile communication systems. Access network equipment can also be access network equipment in open RAN (O-RAN or ORAN) or cloud radio access network (CRAN). Alternatively, access network equipment can also be access network equipment in a communication system resulting from the integration of two or more of the above communication systems.

[0130] Access network equipment includes, but is not limited to: evolved Node B (eNB), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP) in a wireless fidelity (Wi-Fi) system, macro base station, micro base station, wireless relay node, donor node, radio controller in a CRAN scenario, wireless backhaul node, transmission point (TP), or transmission reception point (TRP). Network equipment can also be access network equipment in a 5G mobile communication system. For example, next-generation Node B (gNB) in a new radio (NR) system, transmission reception point (TRP), TP, or one or more antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, network equipment can also be network nodes constituting a gNB or transmission point. Examples include centralized units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), and radio units (RUs). CUs and DUs can be separate entities or included within the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). Alternatively, network equipment can be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, network equipment can be roadside units (RSUs).

[0131] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), centralized unit control plane (CU-CP) can also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, centralized unit user plane (CU-UP) can also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0132] Optionally, the access network equipment may also include a module for implementing sensing functions (i.e., a sensing module). This module can be a new module or an existing module with functional extensions (e.g., sensing functions). The sensing module supports and / or implements sensing functions. For example, it processes sensing signals and / or enables inter-site coordination under sensing functions.

[0133] The communication system provided in this application can incorporate a sensing module to implement some or all sensing-related operations. The sensing module can also be called a sensing unit, sensing processing unit, sensing function module, sensing processor, etc., and this application does not specifically limit its name. The sensing module can be built into a network element of the communication system. For example, the sensing module can be built into: access network equipment, core network equipment, cloud server, or network management (OAM) to implement sensing-related functions. The OAM can be the network management of the core network equipment and / or the network management of the access network equipment. Alternatively, the sensing module can also be an independently configured network element in the communication system. Optionally, the terminal equipment or the chip built into the terminal equipment can also include a sensing module to implement sensing-related functions.

[0134] Figure 3B is another schematic diagram of a communication system according to an embodiment of this application. As shown in Figure 3B, network elements in the communication system are connected via interfaces (e.g., NG interfaces or Xn interfaces) or air interfaces. These network element nodes, such as core network equipment, access network equipment, terminal equipment, or one or more OAM devices, are equipped with one or more sensing modules (only one is shown in Figure 3B for clarity). Access network equipment can be a single access network node or can include multiple access network nodes. For example, access network equipment includes CU and DU. One or more sensing modules can also be provided in the CU and the DU, respectively.

[0135] Optionally, the access network device can be a single access network node or can include multiple access network nodes. For example, it can include CU and DU. One or more sensing modules can be configured in each of the CU and / or DU. Optionally, the CU can also be divided into CU-CP and CU-UP. One or more sensing modules can be configured in each of the CU-CP and / or CU-UP. The sensing modules are used to implement corresponding sensing functions. The sensing modules deployed in different network elements can be the same or different.

[0136] Figure 4 is a schematic diagram of an ORAN system according to an embodiment of this application. The ORAN system includes a core network, access network equipment, and UE. Optionally, the ORAN system may also include other components besides those shown in Figure 4; this application does not limit the specific components included.

[0137] Access network devices can communicate with the core network (CN) via a backhaul link. Access network devices can also communicate with the UE via an air interface. Specifically, the BBU in the access network device communicates with the core network via a backhaul link. The RU in the access network device communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located.

[0138] A BBU consists of at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.

[0139] In one possible implementation, as shown in Figure 5, the CU is a logical node carrying the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. Optionally, the CU can have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0140] Optionally, as shown in Figure 5, the CU can be split into CU-CP and CU-UP. CU-CP is a logical node carrying the RRC layer and the Packet Data Convergence Protocol layer (PDCP-C) control plane layer, used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the AMF network element in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the SDAP layer and the Packet Data Convergence Protocol layer (PDCP-U) user plane layer, used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. In the core network, network elements used to implement user plane functions, such as the user plane function (UPF) network element in a 5G system, are responsible for forwarding and receiving data in terminal devices. The above configuration of CU and DU is merely an example; in practical applications, the functions of CU and DU can be configured as needed. For example, CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For instance, some functions of the RLC layer and protocol layer functions above the RLC layer can be placed in the CU, while the remaining functions of the RLC layer and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of CU or DU can be divided according to service type or other system requirements, such as by latency, placing functions that need to meet low latency requirements in the DU and functions that do not need to meet such latency requirements in the CU.

[0141] In one possible implementation, as shown in Figure 5, the DU is a logical node carrying the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0142] In one possible implementation, as shown in Figure 5, the RU is a logical node carrying both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU may be a 3GPP Transmit Receive Point (TRP), a Remote Radio Header (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0143] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include a Lower-Layer Split control (LLS-C) interface and a Lower-Layer Split user (LLS-U) interface, providing the control plane (C-Plane) and user plane (U-Plane) respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0144] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0145] 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 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.

[0146] Optionally, in the ORAN system, one or more sensing modules can be configured in the CU and / or DU respectively. Optionally, the CU can also be divided into CU-CP and CU-UP. One or more sensing modules can be configured in the CU-CP and / or CU-UP respectively. The sensing modules are used to implement corresponding sensing functions.

[0147] Optionally, in the ORAN system, the sensing module can be a new module set in the CU, or CU-CP, or CU-UP, or DU, or RU. Alternatively, the sensing module can be integrated with existing modules in the CU, or CU-CP, or CU-UP, or DU, or RU, that is, the existing functional modules can be functionally extended to enable them to realize sensing functions.

[0148] It should be noted that the access network equipment can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, control unit, or circuit in the device or apparatus shown above; this application does not impose any specific limitation. It should also be noted that in this application, the term "access network equipment" can refer to either the access network equipment itself or the chip, module, control unit, or circuit within the access network equipment that performs the method provided in this application; this application does not impose any specific limitation.

[0149] The sensing network element possesses sensing management functions. For example, it can select one or more sensing nodes and collect sensing data from those nodes. The sensing network element also fuses sensing data from multiple sensing nodes and uses the fused data to sense the sensing area. It should be noted that the name of the sensing network element may change as the communication system evolves. Any other functional network element with a similar name can be understood as the sensing network element of this application. The name of the sensing network element is not limited. For example, it can also be called a first network element, a sensing functional entity, a sensing measurement network element, or a sensing measurement entity, etc.

[0155] In this application, optionally, "characterize" can be replaced with "indicate".

[0156] Affected by factors such as distance and perspective, the sensing ability of the sensing node is usually limited. As shown in FIG. 6, the sensing node 1 obtains the lateral resolution through the angle measurement ability of the array antenna. According to the form of the antenna array, the lateral resolution can be the azimuth resolution or the elevation resolution. In FIG. 6, the angle resolution provided by the array antenna is Δθ. When the distance between the sensing area and the sensing node is R1, the corresponding lateral resolution is Δa1. When the distance between the sensing area and the sensing node is R2, the corresponding lateral resolution is Δa2. Among them, R1 < R2, Δa1 < Δa2. That is, the lateral resolution increases as the distance between the sensing area and the antenna array increases. The smaller the lateral resolution, the stronger the lateral resolution ability. The larger the lateral resolution, the weaker the lateral resolution ability. Therefore, it can be seen that for a sensing node far from the sensing area, the lateral resolution ability provided by this sensing node is weak.

[0157] In addition, the lateral resolution ability provided by the sensing node is also related to the perspective. The perspective is defined as the direction of the line connecting the positions of the sensing node and the sensing target. In a two-dimensional space, the perspective can be represented by the azimuth angle corresponding to the foregoing line. In a three-dimensional space, the perspective can be represented by the azimuth angle and the elevation angle corresponding to the foregoing line. For different perspectives, the equivalent aperture corresponding to the antenna aperture is different, so the angle resolution of the sensing node is different, and thus the lateral resolution is different. As shown in FIG. 7, the angle resolution of the sensing node at perspective 1 is Δθ1. When the distance between the sensing node and the sensing area is R, the corresponding lateral resolution is Δa1. The angle resolution of the sensing node at perspective 2 is Δθ2. When the distance between the sensing node and the sensing area is R, the corresponding lateral resolution is Δa2. Among them, Δθ1 < Δθ2, Δa1 < Δa2. That is, the larger the angle between the perspective and the normal direction of the antenna aperture, the larger the angle resolution of the sensing node, and the corresponding larger the lateral resolution. Therefore, for the sensing area at certain perspectives, the lateral resolution ability of the sensing node is weak.

[0158] The sensing resolution of a sensing node in various dimensions can include range resolution and lateral resolution. Lateral resolution includes azimuth resolution and pitch resolution. Range resolution, also known as radial resolution, is typically determined by the bandwidth used to transmit sensing signals. Optionally, when a sensing node performs sensing with other sensing nodes, the range resolution is also related to the distance between that sensing node and other sensing nodes. Higher range resolution results in weaker range resolution capability. Lower range resolution results in stronger range resolution. The lateral resolution of a sensing node is related to the distance between the sensing area and the antenna, as well as the viewing angle. Lower lateral resolution results in stronger lateral resolution capability. Higher lateral resolution results in weaker lateral resolution capability.

[0159] In this application, the perception resolution of a sensing node in each dimension is represented by a resolution vector. The resolution vector has various representations, one typical form being: a vector formed by the projections of the spatial resolution of the sensing node in each dimension (distance, azimuth, and pitch) onto the coordinate axes of a global coordinate system, specifically including the vector's length and direction.

[0160] For a sensing node with two-dimensional resolution capability, its lateral resolution can be either azimuth resolution or elevation resolution. When the sensing node's antenna array provides azimuth resolution, its lateral resolution corresponds to the azimuth resolution. When the sensing node's antenna array provides elevation resolution, its lateral resolution corresponds to the elevation resolution.

[0161] The direction of the distance resolution vector is the gradient direction of the longitudinal distance of the sensing node to the target in two-dimensional space. The distance resolution vector characterizes the distance resolution of the sensing node. The length of the distance resolution vector is the value of the distance resolution. Therefore, each component of the distance resolution vector is a projection of the distance resolution vector along the x-axis and y-axis of the global coordinate system.

[0162] The direction of the lateral resolution vector is the gradient direction of the lateral distance of the sensing node to the sensing target in two-dimensional space. The length of the lateral resolution vector is the value of the lateral resolution. Therefore, each component of the lateral resolution vector is a projection of the lateral resolution vector along the x-axis and y-axis of the global coordinate system. Here, the lateral resolution vector can be either the azimuth resolution or the pitch resolution.

[0163] For example, as shown in Figure 8, the distance resolution vector Δr and the azimuth resolution vector Δa of sensing node 1 within the sensing area. Correspondingly, the distance resolution vector can be expressed as Δr = [Δr...]. x ,Δr y The azimuth resolution vector can be represented as Δa = [Δa] x ,Δay ]. Δr x and Δr y Let Δa and Δr represent the components of the distance resolution vector Δr on the x-axis and y-axis, respectively. x and Δa y These represent the x- and y-axis components of the azimuth resolution vector Δa, respectively. The distance resolution vector and the azimuth resolution vector together determine the two-dimensional resolution unit. Please refer to the relevant introduction later for details on resolution units. It should be noted that, typically, the range of the sensing area is relatively small compared to the distance from the sensing area to the sensing node. In this case, the resolution units at different locations within the sensing area are approximate and can be described using the same set of resolution vectors. However, when the sensing area is large, it can be divided into multiple smaller sub-regions. The resolution units at different locations within each sub-region are approximate; that is, the resolution units at different locations within each sub-region can be described using the same set of resolution vectors.

[0164] For a sensing node with three-dimensional resolution, its lateral resolution can include azimuth resolution and pitch resolution. Similarly, the range resolution vector, azimuth resolution vector, and pitch resolution vector of this sensing node can be expressed as Δr = [Δr...]. x ,Δr y ,Δr z ], Δa=[Δa x ,Δa y ,Δa z ], Δe=[Δe x ,Δe y ,Δe z These three factors together determine the resolution unit of a three-dimensional object.

[0165] Therefore, the size of a resolution cell is defined as the size of the region enclosed by a closed contour line or a closed contour surface of the amplitude response of the sensed target. For two-dimensional sensing, the resolution cell is the region enclosed by a contour line. The amplitude value at any point on the contour line is the peak value of the amplitude response of the sensed target minus 3 dB. For a sensing node with three-dimensional resolution capability, the resolution cell is the region enclosed by a contour surface. The amplitude value at any point on the contour surface is the peak value of the amplitude response of the sensed target minus 3 dB. The amplitude response of the sensed target refers to the signal obtained by matched filtering of the echo signal and the transmitted signal. The echo signal is the signal reflected, refracted, or diffracted back from the sensed target by the transmitted signal.

[0166] The amplitude response of a sensed target along various resolution vector directions can typically be represented by a sinc function, the specific parameters of which may differ for different resolution vector directions. For ease of analysis, a quadratic function is used to approximate the sinc function. For a sensing node with two-dimensional resolution capability, assuming it possesses range and lateral resolution capabilities, we will use azimuth resolution as an example. In the range-azimuth coordinate system (ra coordinate system), the target's amplitude response is expressed as:

[0167] The peak value of the amplitude response of the perceived target is normalized to 1. When or g(r,a) = 0.75, meaning the peak attenuation of the target's amplitude response is 3 dB. The power of the target's amplitude response is defined by the closed contour line corresponding to the 3 dB peak attenuation, which determines the resolution cell. This closed contour line can be represented as follows:

[0168] It can be seen that the closed contour line is an elliptic curve in the distance-azimuth coordinate system. Representing the above formula (2) using matrices and vectors,

[0169] Furthermore, based on the distance resolution vector Δr=[Δr x ,Δr y ] and azimuth resolution vector Δa=[Δa x ,Δa y The distance coordinate r and the azimuth coordinate a are transformed into coordinates x and y (xy coordinate system), respectively. The specific formula is as follows (4):

[0170] Formula (4) above can be simplified to:

[0171] in,

[0172] It can be seen that the contour lines of a resolution unit are elliptic curves in the xy coordinate system. Let A... a Defined as the transformation matrix corresponding to the resolution unit. A a Given a positive definite matrix, we perform eigenvalue decomposition to obtain eigenvalues ​​[λ1, λ2]. The square root of the reciprocal of each eigenvalue is the length of the principal axis of the ellipse. Assuming λ1 ≥ λ2, then... It is the length of the shorter principal axis of the ellipse. This is the length of the longer principal axis of the ellipse. Therefore, the size of the resolution unit, which is also the area of ​​the ellipse, is...

[0173] Figure 9 is a schematic diagram of transforming the contour ellipse of a resolution cell from the ra coordinate system to the xy coordinate system. In Figure 9, the range resolution vector and the azimuth resolution vector are orthogonal in the xy coordinate system. Therefore, after transforming from the ra coordinate system to the xy coordinate system, the shape of the contour ellipse of the resolution cell does not change; only its orientation is rotated. In the xy coordinate system, the principal axis of the ellipse remains perpendicular to either the range resolution vector or the azimuth resolution vector.

[0174] Figure 10 is another schematic diagram of transforming the contour ellipse of a resolution cell from the ra coordinate system to the xy coordinate system. In Figure 10, the range resolution vector and the azimuth resolution vector are not orthogonal in the xy coordinate system. Therefore, after transforming from the ra coordinate system to the xy coordinate system, the contour lines of the resolution cell not only rotate in direction but also change in shape. In Figure 10, the principal axes of the contour ellipse are no longer perpendicular to the range resolution vector or the azimuth resolution vector. In Figure 10, the two principal axes of the contour ellipse are... and

[0175] Similarly, for 3D perception, the resolution unit is an ellipsoid in the xyz coordinate system. The size of the resolution unit is the volume of the ellipsoid. Furthermore, based on the distance resolution vector Δr = [Δr x ,Δr y ], Azimuth resolution vector Δa=[Δa x ,Δa y ] and pitch resolution vector Δe=[Δe x ,Δe y ,Δe z The transformation matrix A can be obtained from this. b The specific formula is as follows (6):

[0176] For transformation matrix A b Performing eigenvalue decomposition yields eigenvalues ​​[λ1, λ2, λ3], then the size of the resolution cell is the volume of the ellipsoid.

[0177] Therefore, the size of a resolution cell is defined as the area of ​​the contour ellipse or the volume of the contour ellipsoid corresponding to that cell. The area of ​​the contour ellipse or the volume of the contour ellipsoid can both be calculated using the resolution vector.

[0178] For scenarios involving joint sensing by multiple sensing nodes, assuming that the joint sensing measurement of the sensing management function involves weighting the sensing data generated by each sensing node, as shown in Figure 11, different weight coefficients are assigned to the sensing data generated by different sensing nodes. The weight coefficients of multiple sensing nodes satisfy a normalization condition, which yields the following:

[0179] Where, α i Let be the weight coefficient of sensing node i, and N be the number of sensing nodes. The transformation matrix A corresponding to the resolution unit of the merged sensing data is a weighted sum of the transformation matrices corresponding to the resolution units of each sensing node, which can be obtained as follows:

[0180] Among them, A i Let be the transformation matrix of the sensing node.

[0181] Therefore, it can be seen that the merged transformation matrix A is different under different weighting coefficients, that is, the resolution unit size of the merged sensing data is different. Thus, the weighting coefficients of multiple sensing nodes are optimized with the goal of minimizing the resolution unit size of the merged sensing data. Combining the previous analysis regarding resolution unit size, minimizing the resolution unit size is equivalent to maximizing the product of the eigenvalues ​​of the merged transformation matrix A, which is further equivalent to maximizing the determinant of the transformation matrix A, i.e., solving the following optimization problem:

[0182] in,

[0183] A i >0

[0184] Specifically, Newton's method can be used to solve the above problem, thereby obtaining a set of optimal weight coefficients. This set of optimal weight coefficients includes the weight coefficients of multiple sensing nodes.

[0185] Sensing data contains noise, and each sensing node's sensing data has a corresponding signal-to-noise ratio (SNR). Given the transmission power of the sensing signal from a sensing node and the path loss in the sensing area of ​​that node (represented by a linear coefficient greater than 0), the SNR of the sensing data from that node is directly proportional to the product of the node's transmission power (the power of the transmitted sensing signal) and the path loss. For example, the SNR of the sensing data from sensing node i is γ. i The path loss of sensing node i is β. i The transmit power of sensing node i is p i Satisfying γ i ∝β i p i .

[0186] By combining sensing data according to the maximum ratio combining (MRC) criterion, the signal-to-noise ratio (SNR) of the combined sensing data can be maximized. Therefore, given a set of optimal weighting coefficients, the transmit power (power of the transmitted sensing signal) of the sensing nodes should be adjusted to conform to the MRC criterion. This avoids power waste and improves sensing performance. In the MRC criterion, the weighting coefficients are proportional to the square root of the SNR. For example, the weighting coefficient of sensing node i is α. i ,satisfy Therefore, the transmit power p of the sensing signal sent by sensing node i i It should meet the following requirements: Where P ref This is used as a reference power. The same principle applies to other sensing nodes; here, we take sensing node i as an example to introduce the technical solution of this application.

[0187] Therefore, in one possible example, as shown in Figure 12, the perception management function can acquire the resolution vectors (distance, azimuth, and pitch) of multiple sensing nodes in various dimensions. Then, the perception management function combines the resolution vectors of each sensing node to determine the transformation matrix corresponding to the resolution unit of each sensing node. The perception management function then uses the transformation matrix corresponding to the resolution unit of each sensing node to determine the weight coefficients of each sensing node, and based on these weight coefficients, determines the transmission power of the sensing signal transmitted by each sensing node.

For details on the representation of the resolution vectors, please refer to the previous introduction; they will not be repeated here.

[0197] In one possible implementation, if the second communication device has two-dimensional resolution capability, then the sensing resolution information supported by the second communication device includes a first resolution vector and a second resolution vector, or includes a first resolution vector and a third resolution vector.

[0198] In another possible implementation, if the second communication device has three-dimensional resolution capability, then the perception resolution information supported by the second communication device includes a first resolution vector, a second resolution vector, and a third resolution vector.

[0199] Specifically, the second communication device determines the sensing resolution information it supports based on the sensing area.

Optionally, the path loss corresponding to the second communication device is related to the signal frequency used by the second communication device during sensing, the distance from the transmitting end of the sensing signal to the sensing area, and the distance from the receiving end of the sensing signal to the sensing area.

[0207] In one possible implementation, the second communication device transmits a wireless signal and receives the echo signal of that wireless signal. Then, the second communication device estimates the power loss of the wireless signal during propagation based on the wireless signal and the echo signal, thereby obtaining the path loss of the second communication device.

This scaling factor is used to adjust the transmit power of the reference signal, thereby achieving purposes such as controlling the signal-to-noise ratio and coordinating interference between devices. Similarly, the amplitude scaling factor of the sensed channel refers to the scaling factor applied to the physical layer channel when the sensed signal is carried on the corresponding physical layer channel.

For example, the transmission power of the second communication device is used by the second communication device to transmit sensing signals. For example, the second information includes the transmission power of the second communication device. It should be noted that when the transmission power of the second communication device is zero, it indicates that the first communication device has instructed the second communication device not to participate in sensing.

[0492] When data needs to be transmitted, the processor performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency (RF) circuit. The RF circuit then processes the baseband signal and transmits it outwards as electromagnetic waves via an antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna. The RF circuit converts the RF signal back into a baseband signal and outputs it to the processor. The processor converts the baseband signal back into data and processes the data. For ease of explanation, Figure 20 only shows one memory, processor, and transceiver.
