[0001] This application claims priority to Chinese Patent Application No. 202411730314.7, filed with the China National Intellectual Property Administration on November 28, 2024, entitled "Communication Method, Communication Device and System", 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 communication methods, communication devices, and systems. Background Technology

[0003] With the development and advancement of communication technology, in future cellular networks, base stations will not only be able to interconnect people and things, but will also have sensing capabilities. For example, transmitting nodes (such as base stations) can send sensing signals, and receiving nodes (such as terminals) can receive the echo signals of these sensing signals to detect targets and estimate the speed, distance, angle, trajectory, shape, and size of the detected targets.

[0004] Currently, in sensing scenarios, network devices and terminal devices need to interact to exchange sensing-related information (or sensing auxiliary data), such as the configuration information of sensing signals and the sensing area. How to transmit sensing auxiliary data flexibly and efficiently is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application discloses a communication method, communication device, and system that can transmit sensing auxiliary data flexibly and efficiently.

[0006] The present application is described below from different aspects. It should be understood that the different implementation methods and beneficial effects described below can be referenced from each other.

[0007] In a first aspect, this application provides a communication method that can be executed by a first device. The first device may be the first device itself (such as a network device or a terminal device) or a module (e.g., a chip, a chip system, an integrated circuit, or a control unit) in the first device, or a software and / or hardware module for implementing the functions of the first device. Taking the execution of the method by the first device itself as an example, the method may include: the first device sending first information, the first information being scheduling information for indicating second information, the second information being sensing auxiliary data; the first device sending second information, wherein the first information and / or the second information are sent via broadcast.

[0008] In this embodiment of the application, the first device can indicate the scheduling information of the second information (or sensing auxiliary data) to the second device, and the second device can determine on its own whether to receive the sensing auxiliary data and which sensing auxiliary data to receive, which can improve the flexibility of sensing auxiliary data transmission between the first device and the second device.

[0009] In this embodiment, if the first device broadcasts sensing auxiliary data, multiple second devices can simultaneously receive the sensing auxiliary data, thereby improving the transmission efficiency of sensing auxiliary data between the first and second devices and reducing the communication pressure between the first device and the multiple second devices. The first device does not need to send different sensing auxiliary data to different second devices individually, which reduces the complexity of the first device sending sensing auxiliary data and improves the transmission efficiency of sensing auxiliary data between the first and second devices. If the first device broadcasts first information (i.e., sensing auxiliary data scheduling information), multiple second devices can simultaneously receive the first information. The second devices can determine whether to receive sensing auxiliary data and which sensing auxiliary data to receive based on the first information. The first device does not need to send different sensing auxiliary data to different second devices individually, which reduces the complexity of the first device sending sensing auxiliary data and improves the transmission efficiency of sensing auxiliary data between the first and second devices.

For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one item", "one or more of the following", or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent: a, b, c; a and b; a and c; b and c; or a and b and c. Here, a, b, and c can be single or multiple.

[0074] In the description of this application, the words "exemplary" or "for example" are used to indicate that something is an example, illustration, or illustration. Any embodiment or design that is described as "exemplary," "for example," or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of the words "exemplary," "for example," or "for example" is intended to present the relevant concepts in a specific manner.

[0075] It is understood that in the description of this application, "when," "if," and "if" all refer to the device performing a corresponding action under certain objective circumstances, and are not time-limited, nor do they require the device to perform a judgment action when it is implemented, nor do they imply any other limitations. The device performing a corresponding action under certain objective circumstances includes: satisfying the objective circumstances, i.e., being able to perform the corresponding action; or satisfying both the objective circumstances and other circumstances, in order to perform the corresponding action.

[0076] In this application, the use of singular designations for elements is intended to represent "one or more" rather than "one and only one," unless otherwise specified.

[0077] In addition, the terms “system” and “network” are often used interchangeably in this article.

[0078] It is understood that in the various embodiments of this application, expressions such as "A corresponds to B", "A and B correspond", "A corresponds to B" or similar expressions indicate that B is associated with A, and B can be determined based on A. Determining B based on A does not mean that B is determined solely based on A; B can also be determined based on A and / or other information.

[0079] Please refer to Figure 1A, which is a schematic diagram of the architecture of the communication system applied in the embodiments of this application. It should be noted that Figure 1A is a possible, non-limiting system schematic diagram. As shown in Figure 1A, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system may also include an Internet 300. RAN 100 includes at least one RAN node (110a and 110b in Figure 1A, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1A, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1A). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is connected to core network 200 wirelessly or via a wired connection. The core network elements in core network 200 and RAN nodes 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions, or a single physical device integrating some core network element functions and some RAN node 110 functions. Terminals can be interconnected with each other, and RAN nodes 110 can be interconnected with each other via wired or wireless means. Figure 1A is only a schematic diagram; this communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices. Each device may also include different functional units, which are not shown in Figure 1A.

[0080] In this embodiment of the application, the first device can be RAN 100 in FIG1A, and the second device can be terminal 120 in FIG1A; or, the first device and the second device can both be terminals, for example, the first device and the second device can be any two terminals in terminal 120 in FIG1A.

[0081] In this application, the network device can be RAN node 110.

[0082] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems. RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0083] RAN node 110, sometimes also referred to as a radio access network device, access network apparatus, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in the communication system can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, in Figure 1A, network element 120i can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 100 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, in Figure 1A, network elements 110a and 110b can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0084] In one possible scenario, RAN node 110 can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system. RAN node 110 can be a macro base station (as shown in Figure 1A, 110a), a micro base station or indoor station (as shown in Figure 1A, 110b), a relay node or donor node, or a radio controller in a CRAN scenario. Optionally, RAN node 110 can also be a server, a wearable device, a vehicle, or in-vehicle equipment. For example, the access network device in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). All or part of the functions of RAN node 110 in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). In this application, RAN node 110 can also be a logical node, logical module, or software that can implement all or part of the functions of RAN node 110.

[0085] In another possible scenario, multiple RAN nodes 110 collaborate to assist the terminal in achieving wireless access, with each RAN node 110 implementing a portion of the base station's functions. For example, a RAN node 110 can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0086] 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. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0087] For example, please refer to Figure 1B, which is a schematic diagram of the architecture of the O-RAN system provided in this application. Figure 1B is only a schematic diagram, and the O-RAN system may also include other components besides those shown in Figure 1B. As shown in Figure 1B, the access network device (e.g., it may be an eNB, gNB, or next-generation access network device) communicates with the core network elements in the CN through a backhaul link and communicates with the terminal through the air interface.

[0088] Specifically, the BBU in the access network device communicates with the core network elements in the CN via a backhaul link, and the RU in the access network device communicates with at least one terminal 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. The BBU includes at least one CU and at least one DU, which can communicate via at least one midhaul link.

[0089] Figure 1C illustrates a schematic diagram of the network element function division and protocol layer structure of an O-RAN device. In some examples, the CU is a logical node carrying the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU connects to network nodes such as the core network through interfaces, which can be interfaces such as E2 interfaces. Optionally, the CU may have some of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) connects to the DU (e.g., the radio link control (RLC) layer and lower layers) through interfaces, which can be interfaces such as F1 interfaces. In some examples, these interfaces (e.g., 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.). The F1 application (AP) protocol is the application protocol of the F1 interface, and in some examples, it defines the signaling procedures of F1. The F1 interface supports the control plane F1-C and the user plane F1-U.

[0090] In some examples, the CU can be split into CU-CP (control unit-control plane) and CU-UP (control unit-user plane). CU-CP is a logical node carrying the RRC layer and PDCP-C (control plane part of PDCP) 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 access and mobility management function (AMF) in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal location updates, terminal registration with the network, and terminal handover. CU-UP is a logical node carrying the SDAP layer and PDCP-U (user plane part of PDCP) 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. These network elements in the core network, such as the user plane function (UPF) in a 5G system, are responsible for data forwarding and receiving in the terminal. The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0091] In some examples, a DU is a logical node that carries the radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a 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.

[0092] In some examples, the RU is a logical node that carries both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP TRP, a remote radio head (RRH), or other similar entity. 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 terminals via a wireless link.

[0093] 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 LLS-C and LLS-U interfaces 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 an LLS-M interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0094] 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.

[0095] A terminal is a device or module that connects to the aforementioned communication system and possesses corresponding communication functions. Terminals can also be referred to as terminal equipment, user equipment (UE), user devices, access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, terminal units, terminal stations, terminal devices, wireless communication equipment, user agents, or user devices, etc. Terminals typically contain communication modules, circuits, or chips that perform the corresponding communication functions. They can also be configured with program instructions for performing these functions. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, transportation vehicle with wireless communication function, communication module, roadside unit (RSU) with terminal function, etc. The embodiments of this application do not limit the device form of the terminal.

[0096] For ease of description, the following description uses a base station as an example of RAN node 110. Base stations and terminals can be fixed or mobile. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0097] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1A can be configured as a mobile base station. For terminals 120j that access the wireless access network 100 through 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol. In this case, relative to 110a, 120i is also a base station. Therefore, both base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1A can be called communication devices with base station functions, and 120a-120j in Figure 1A can be called communication devices with terminal functions.

[0098] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0099] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0100] In this application, the base station sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, with the uplink information carried on the uplink channel. To communicate with the base station, the terminal needs to establish a radio connection on a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the terminal's serving cell. When the terminal communicates with this serving cell, it is also susceptible to interference from signals from neighboring cells.

[0101] In this application, "sending information" can be understood as one device sending information to another device, or it can also be understood as one logical module within a device sending information to another logical module. For example, "base station sending information" can be understood as the base station sending information to another device (such as a terminal), or it can be understood as logical module 1 in the base station sending information to logical module 2 in the base station.

[0102] In this application, "receiving information" can be understood as one device receiving information from another device, or it can also be understood as a logical module within a device receiving information from another logical module. For example, "base station receiving information" can be understood as the base station receiving information from another device (such as a terminal), or it can be understood as logical module 1 in the base station receiving information from logical module 2 in the base station.

[0103] The communication between different devices involved in this application can refer to direct communication between different devices (i.e., without the need for relaying or forwarding by other devices), or communication between different devices through other devices (i.e., requiring relaying or forwarding by other devices), or communication between a functional unit within a device and other devices through another functional unit. In other words, "sending information to… (e.g., a terminal)" or the relevant illustrations in the accompanying drawings can be understood as the destination of the information being the terminal. This can include sending information directly or indirectly to the terminal. "Receiving information from… (e.g., a terminal)" or "receiving information from… (e.g., a terminal)" or "receiving information sent (e.g., by a terminal)" or the relevant illustrations in the accompanying drawings can be understood as the source of the information being the terminal. This can include receiving information directly or indirectly from the terminal. Information may undergo necessary processing between the source and destination, such as format changes, analog-to-digital conversion, amplification, filtering, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be elaborated further here.

[0104] The technical terms and related technologies involved in this application are described below.

[0105] I. Perception

[0106] 1. Wireless sensing (or perception)

[0107] Wireless sensing uses wireless signals for perception. Sensing is the process of collecting, processing, and generating sensing results from data. For example, data can be used to determine the distance, shape, and type of surrounding obstacles, or to determine the breathing rate and heart rate of a monitored object. The collected data can be obtained through sensors or through wireless signals.

[0108] 2. Perception Mode

[0109] The sensing modes can be divided into sensing modes based on access network devices, sensing modes based on both access network devices and terminal devices, and sensing modes based on terminal devices. Figure 2 is a schematic diagram of the sensing modes provided in an embodiment of this application.

[0110] The sensing mode 1 shown in Figure 2 is a sensing mode based on access network equipment. The access network equipment acts as both the transmitting (TX) and receiving (RX) end of the sensing signal. For example, when the sensing signal 1 transmitted by the access network equipment reaches the target object (e.g., a person), after the sensing signal 1 is reflected, scattered, and diffracted by the target object, the access network equipment can receive the sensing signal 2, and then process the sensing signal 2 to obtain the sensing result.

[0111] Taking the access network equipment as a base station (BS) as an example, the sensing mode 1 can be a single base station (BS Monostatic). BS Monostatic means that the base station acts as both a transmitter and a receiver. The signal is directly transmitted from the base station and received by the same base station. The base station calculates the sensing result based on the received signal.

[0112] The sensing mode 2 shown in Figure 2 is also a sensing mode based on access network devices. One access network device acts as the sensing signal transmitter (TX), and the other access network device acts as the sensing signal receiver (RX). For example, when the sensing signal 1 transmitted by the access network device acting as TX reaches the target object, the sensing signal 1 is reflected, scattered, and diffracted by the target object. The access network device acting as RX can then receive the sensing signal 2, and process the sensing signal 2 to obtain the sensing result.

[0113] Taking the access network equipment as a base station as an example, sensing mode 2 can be a base station-to-base station bistatic (BS-BS Bistatic) mode. In this bistatic mode, one base station acts as a transmitter to transmit signals, while the other base station acts as a receiver to receive signals. The base station receiving the signals calculates the sensing results based on the received signals. In both BS Monostatic and BS-BS Bistatic modes, the BS can place information related to the sensing results in the sensing system information and provide it to the UE. Specifically, the sensing information types of the base station can include: whether sensing is supported, whether sensing results already exist; it can also describe in more detail auxiliary data related to sensing AOI, target ID, sensing results, sensing quality, etc.

[0114] The sensing mode 3 shown in Figure 2 is a sensing mode based on access network equipment and terminal equipment. The access network equipment acts as the sensing signal transmitter, and the terminal equipment acts as the sensing signal receiver. For example, when sensing signal 1 sent by the access network equipment reaches the target object, after the sensing signal 1 is reflected, scattered, and diffracted by the target object, the terminal equipment can receive sensing signal 2. The terminal equipment can then process sensing signal 2 to obtain the sensing result.

[0115] Taking the access network equipment as the base station and the terminal equipment as the user equipment (UE) as an example, perception mode 3 can be a base station-UE bistatic (BS-UE Bistatic) mode, where the base station acts as the transmitter and the UE acts as the receiver. In this mode, the signal transmitted by the base station is received by the UE. The UE calculates the perception result based on the received signal. At this time, the BS needs to send the perception signal configuration information, base station location information, base station beam information, time synchronization information between the base station and the UE, and phase synchronization information between the base station and the UE to the UE. Compared with the positioning scenario, the newly added system information types include: perception signal configuration information and phase synchronization information between the base station and the UE.

[0116] The sensing mode 4 shown in Figure 2 is also a sensing mode based on access network equipment and terminal equipment. The terminal equipment acts as the sensing signal transmitter, and the access network equipment acts as the sensing signal receiver. For example, when the sensing signal 1 sent by the terminal equipment reaches the target object, after the sensing signal 1 is reflected, scattered, and diffracted by the target object, the access network equipment can receive the sensing signal 2. The access network equipment can then process the sensing signal 2 to obtain the sensing result.

[0117] Taking the access network equipment as the base station and the terminal equipment as the UE as an example, perception mode 4 can be UE-BS Bistatic, where the UE acts as the transmitter and the base station as the receiver. The base station calculates the perception result based on the received signal. In this case, the BS needs to inform the UE of the configuration for transmitting the reference signal, the beam information used by the UE, the antenna mode used by the UE (such as which elements are used, the polarization and spacing of the elements, and the orientation of the antenna plane), the time synchronization information between the base station and the UE, and the phase synchronization information between the base station and the UE.

[0118] The sensing mode 5 shown in Figure 2 is a terminal device-based sensing mode, where the terminal device acts as both the transmitter and receiver of sensing signals. For example, when sensing signal 1 sent by the terminal device reaches the target object, after the sensing signal 1 is reflected, scattered, and diffracted by the target object, the terminal device can receive sensing signal 2, and then process sensing signal 2 to obtain the sensing result.

[0119] Taking the UE as an example, perception mode 5 can be UE Monostatic, meaning the UE acts as both a transmitter and a receiver. In this mode, the signal emitted by the UE is received by itself.

[0120] The sensing mode 6 shown in Figure 2 is also a terminal device-based sensing mode, where one terminal device acts as the sensing signal transmitter and the other terminal device acts as the sensing signal receiver. For example, sensing signal 1 sent by the terminal device acting as TX reaches the target object. After being reflected, scattered, and diffracted by the target object, sensing signal 1 can be received by the terminal device acting as RX, which can then process sensing signal 2 to obtain the sensing result.

[0121] Taking the UE as an example, perception mode 6 can be UE-UE bistatic, where one UE acts as a transmitter and the other as a receiver. The UE that receives the signal calculates the perception result based on the received signal. In this case, the base station can control the perception parameters. The base station needs to inform the UE of the configuration for sending reference signals, the BS needs to inform the UE of the antenna mode used, and the priority of the UE's perception service (used to determine the priority of the UE's perception through the sidelink method).

[0122] The aforementioned sensing signal 2 can be understood as the echo signal of the aforementioned sensing signal 1. The sensing signal 2 carries more information than the sensing signal 1. For example, the sensing signal 2 can carry source information and environmental information.

[0123] It should be noted that the perception mode can also be called the perception scene or other names. For example, "perception mode" can also be replaced with "perception scene". This application does not limit this.

[0124] Currently, network devices and terminal devices often transmit sensing auxiliary data in a one-to-one manner. This sensing auxiliary data includes auxiliary data, information on reference signals used for sensing, and sensing result information. For example, auxiliary data includes TRP information, the sensed area of ​​interest (AOI), and the tracking target ID; sensing result information includes the position, distance, angle, speed, intensity, and material of the sensed target.

[0125] In this application, the first device can indicate the scheduling information of the sensing auxiliary data to the second device, and the second device can determine whether to receive the sensing auxiliary data and which sensing auxiliary data to receive, thereby improving the flexibility of sensing auxiliary data transmission between the first device and the second device; the first device can uniformly transmit the configuration data (i.e., the aforementioned sensing auxiliary data) shared by the second device (such as the UE in the base station) through broadcasting, which can reduce the communication pressure between the first device and the second device.

[0126] Based on the above system architecture, a communication method provided by an embodiment of this application will be described below.

[0127] Please refer to Figure 3, which is a flowchart illustrating a communication method provided in an embodiment of this application.

[0128] In this application embodiment, the steps performed by the first device can also be performed by a module (e.g., a chip, chip system, integrated circuit, or control unit) in the first device; in this application embodiment, the steps performed by the second device can also be performed by a module (e.g., a chip, chip system, integrated circuit, or control unit) in the second device.

[0129] As shown in Figure 3, the communication method may include steps S301-S302:

[0130] Step S301: The first device sends first information to the second device. The first information is used to indicate the scheduling information of the second information, and the second information is sensing auxiliary data.

[0131] Correspondingly, the second device receives the first information sent from the first device.

[0132] In one implementation, the first device can send a first message, which includes first information, and the first message is a broadcast message. That is to say, the aforementioned first information can be carried in the broadcast message, or in other words, the first device broadcasts the first information. For example, the broadcast message can be a system information block (SIB) message.

[0133] Optionally, the first device (such as a network device) may send the first information after receiving a request from the second device (such as a terminal device). For example, the request may be used to request the second information; or the request may also carry the type or identifier of the second information.

[0134] For example, the second information may be a separate information block (also referred to as a sensing system information block) or an information block in a broadcast message (such as an SIB). This application does not limit the name of the second information.

[0135] Optionally, the first information is used to indicate at least one of the scheduling period of the second information, the broadcast status of the second information, or the type of the second information, wherein the broadcast status of the second information includes the second information being broadcast and / or the second information being provided when requested by the second device.

[0136] Optionally, the second information includes N pieces of sensory information, where N is a positive integer. For example, the N pieces of sensory information may include at least one of the following: first indication information, second indication information, third indication information, fourth indication information, fifth indication information, sixth indication information, seventh indication information, eighth indication information, ninth indication information, tenth indication information, eleventh indication information, twelfth indication information, thirteenth indication information, fourteenth indication information, or fifteenth indication information.

[0137] The first indication information indicates whether the first device supports sensing or not; the second indication information indicates whether the first device has sensing results or not; the third indication information indicates a first area, such as a region of interest (AOI) or a sensing area; the fourth indication information indicates the sensing target, such as the target's ID; the fifth indication information indicates the sensing result information of the target, such as the target's position, distance, angle, speed, intensity, or material; the sixth indication information indicates the quality of service (QS), such as angle measurement capability, distance measurement capability, speed measurement capability, reconstruction accuracy, positioning accuracy, or velocity measurement accuracy; and the seventh indication information indicates the configuration information of the sensing signal, such as the time and frequency resources occupied by the sensing signal transmission. The following information is provided: the eighth indication information indicates the phase synchronization information between the sensing signal transmitter and the sensing signal receiver; the ninth indication information indicates the method by which the sensing signal transmitter transmits sensing signals (such as reference signals RS); the tenth indication information indicates the antenna information used by the sensing signal transmitter to transmit sensing signals, for example, the antenna information may include at least one of the following: array information, polarization, spacing, or antenna panel orientation; the eleventh indication information indicates the priority information of sensing by the sensing signal transmitter through the side link, for example, this priority may be used to indicate whether sensing through the side link has a higher priority than other services (such as communication) through other links; the twelfth indication information indicates the location information of the first device; the thirteenth indication information indicates the beam information of the first device; the fourteenth indication information indicates the time synchronization information between the sensing signal transmitter and the sensing signal receiver; and the fifteenth indication information indicates the beam information of the second device.

[0138] Optionally, if the second information includes N perceptual information items, then the type of the second information includes N types, with each of the N types corresponding one-to-one with one of the N perceptual information items, where N is a positive integer. That is, each perceptual information item corresponds to one type. When the second information includes multiple perceptual information items, the type of the second information can refer to the type corresponding to each of the multiple perceptual information items.

[0139] Optionally, the type of perceived information is related to the content of the perceived information. This can mean that the type of perceived information is categorized based on its content.

[0140] For example, the type of the first indication information is used to indicate whether the first device supports sensing, or in other words, the type of the first indication information is used to indicate whether the first indication information is related to whether the first device supports sensing; the type of the second indication information is used to indicate whether the first device has already achieved sensing results, or in other words, the type of the second indication information is used to indicate whether the second indication information is related to whether the first device has already achieved sensing results; the type of the third indication information is used to indicate that the third indication information is related to the first area, but the type of the third indication information does not indicate the specific content of the first area; the type of the fourth indication information is used to indicate that the fourth indication information is related to the sensing target, but the type of the fourth indication information does not indicate the specific content of the sensing target; the type of the fifth indication information is used to indicate that the fifth indication information is related to the sensing result information of the sensing target, or in other words, the type of the fifth indication information is used to indicate that the content indicated by the fifth indication information is the sensing result information of the sensing target, but the type of the fifth indication information does not indicate the specific content of the sensing result information of the sensing target; the type of the sixth indication information is used to indicate the quality of sensing service, or in other words, the type of the sixth indication information is used to indicate that the content indicated by the sixth indication information is the quality of sensing service, but the type of the fifth indication information does not indicate the specific content of the quality of sensing service; the type of the seventh indication information is used to indicate the configuration information of the sensing signal, or The seventh indication information type indicates that the content indicated by the seventh indication information is configuration information of the sensing signal, but the type of the seventh indication information does not indicate the specific content of the configuration information of the sensing signal; the eighth indication information type indicates the phase synchronization information between the sensing signal transmitter and the sensing signal receiver, or in other words, the type of the eighth indication information indicates that the content indicated by the eighth indication information is phase synchronization information between the sensing signal transmitter and the sensing signal receiver, but the type of the eighth indication information does not indicate the specific content of the phase synchronization information between the sensing signal transmitter and the sensing signal receiver; the ninth indication information type indicates the method by which the sensing signal transmitter transmits the sensing signal, or in other words, the type of the ninth indication information indicates that the content indicated by the ninth indication information is the method by which the sensing signal transmitter transmits the sensing signal, but the type of the ninth indication information does not indicate the specific content of the method by which the sensing signal transmitter transmits the sensing signal; the tenth indication information type indicates the information of the antenna used by the sensing signal transmitter to transmit the sensing signal, or in other words, the type of the tenth indication information indicates that the content indicated by the tenth indication information is the information of the antenna used by the sensing signal transmitter to transmit the sensing signal, but the type of the tenth indication information does not indicate the specific content of the information of the antenna used by the sensing signal transmitter to transmit the sensing signal.The type of the eleventh indication information is used to indicate the priority information sensed by the sensing signal transmitter through the side link. In other words, the type of the eleventh indication information indicates that the content indicated by the eleventh indication information is priority information sensed by the sensing signal transmitter through the side link, but the type of the eleventh indication information does not indicate the specific content of the priority information sensed by the sensing signal transmitter through the side link. The type of the twelfth indication information is used to indicate the location information of the first device. In other words, the type of the twelfth indication information indicates that the content indicated by the twelfth indication information is the location information of the first device, but the type of the twelfth indication information does not indicate the specific content of the location information of the first device. The type of the thirteenth indication information is used to indicate the beam information of the first device. In other words, the type of the thirteenth indication information indicates the beam information indicated by the thirteenth indication information. The content is the beam information of the first device, but the type of the thirteenth indication information does not indicate the specific content of the beam information of the first device; the type of the fourteenth indication information is used to indicate the time synchronization information between the sensing signal transmitter and the sensing signal receiver, or in other words, the type of the fourteenth indication information is used to indicate that the content indicated by the fourteenth indication information is the time synchronization information between the sensing signal transmitter and the sensing signal receiver, but the type of the fourteenth indication information does not indicate the specific content of the time synchronization information between the sensing signal transmitter and the sensing signal receiver; the type of the fifteenth indication information is used to indicate the beam information of the second device, or in other words, the type of the fifteenth indication information is used to indicate that the content indicated by the fifteenth indication information is the beam information of the second device, but the type of the fifteenth indication information does not indicate the specific content of the beam information of the second device.

[0141] In one implementation, the second information is associated with a sensing mode. For example, the association of the second information with a sensing mode can mean that each sensing mode corresponds to at least one piece of second information; or, each piece of second information corresponds to at least one sensing mode; or, the first device sends the second information based on the sensing mode. It should be noted that the second information corresponding to different sensing modes can be the same or different; the second information sent by the first device for different sensing modes can be the same or different, and this application does not limit this. Wherein, the second information corresponding to multiple sensing modes can mean that the second information applies to multiple sensing modes, or, the second information sent by the first device for multiple sensing modes is the same.

[0142] The sensing modes in this application include a first sensing mode, a second sensing mode, a third sensing mode, a fourth sensing mode, a fifth sensing mode, and a sixth sensing mode. In the first sensing mode, the sensing signal transmitter and the sensing signal receiver are both first devices, as exemplified by the description of sensing mode 1 in Figure 2. In the second sensing mode, the sensing signal transmitter and the sensing signal receiver are different first devices, as exemplified by the description of sensing mode 2 in Figure 2. In the third sensing mode, the sensing signal transmitter is a first device and the sensing signal receiver is a second device, as exemplified by the description of sensing mode 3 in Figure 2. In the fourth sensing mode, the sensing signal transmitter is a second device and the sensing signal receiver is a first device, as exemplified by the description of sensing mode 4 in Figure 2. In the fifth sensing mode, the sensing signal transmitter and the sensing signal receiver are the same second device, as exemplified by the description of sensing mode 5 in Figure 2. In the sixth sensing mode, the sensing signal transmitter and the sensing signal receiver are different second devices, as exemplified by the description of sensing mode 6 in Figure 2.

[0143] For example, if the second information corresponds to the first sensing mode or the second sensing mode, then the second information may include at least one of the following: first indication information, second indication information, third indication information, fourth indication information, fifth indication information, or sixth indication information. That is to say, the second information sent by the first device for the first sensing mode and the second sensing mode may include at least one of the following: first indication information, second indication information, third indication information, fourth indication information, fifth indication information, or sixth indication information.

[0144] For example, if the second information corresponds to the third sensing mode, then the second information may include at least one of the seventh, eighth, twelfth, thirteenth, or fourteenth indication information. That is to say, the second information sent by the first device for the third sensing mode may include at least one of the seventh, eighth, twelfth, thirteenth, or fourteenth indication information.

[0145] For example, the second information corresponds to the fourth sensing mode, and the second information includes at least one of the eighth, ninth, tenth, eleventh, fourteenth, or fifteenth indication information. That is to say, the second information sent by the first device for the fourth sensing mode may include at least one of the eighth, ninth, tenth, eleventh, fourteenth, or fifteenth indication information.

[0146] For example, if the second information corresponds to the fifth or sixth sensing mode, then the second information may include at least one of the ninth, tenth, or eleventh indication information. That is to say, the second information sent by the first device for the fifth or sixth sensing mode may include at least one of the ninth, tenth, or eleventh indication information.

[0147] It should be noted that the second information corresponding to the different perception modes mentioned above is only an example. Perception modes may also correspond to more or less second information, and should not be construed as limiting the relationship between perception modes and second information.

[0148] This application does not limit the number of sensing modes. For example, if the first device is a network device and the second device is a terminal, the sensing modes corresponding to the first device and the second device can be any one of the above-mentioned first sensing modes to the sixth sensing mode. For another example, when both the first device and the second device are terminals, the sensing modes corresponding to the first device and the second device can be the above-mentioned fifth sensing mode and / or the sixth sensing mode.

[0149] Optionally, the type of the second information is also used to indicate the perception mode corresponding to the second information, which includes one of the first perception mode, the second perception mode, the third perception mode, the fourth perception mode, the fifth perception mode, and the sixth perception mode.

[0150] In one implementation, the second information is related to a sensing method. For example, the sensing method may include at least one of ranging, angle measurement, or velocity measurement. For instance, the second information being related to a sensing method could mean that each sensing method corresponds to at least one piece of second information; or that each piece of second information corresponds to at least one sensing method; or that the first device transmits the second information based on the sensing method. It should be noted that the second information corresponding to different sensing methods may be the same or different; the second information transmitted by the first device for different sensing methods may be the same or different, and this application does not limit this.

[0151] For example, if the second information is used for distance measurement, the second information may include at least one of the third, seventh, twelfth, or fourteenth indication information.

[0152] For example, if the second information is used for angle measurement, then the second information includes at least one of the third, seventh, tenth, twelfth, or thirteenth indication information.

[0153] For example, if the second information is used for speed measurement, then the second information includes at least one of the fourth, eighth, twelfth, or fourteenth indication information.

[0154] In this application, "second information used for distance measurement" can mean that the second information is related to distance measurement, or that the sensing method corresponding to the second information is distance measurement, or that the second information is data used by the sensing signal receiver and the sensing signal transmitter when performing distance measurement. "Second information used for angle measurement" can mean that the second information is related to angle measurement, or that the sensing method corresponding to the second information is angle measurement, or that the second information is data used by the sensing signal receiver and the sensing signal transmitter when performing angle measurement. "Second information used for speed measurement" can mean that the second information is related to speed measurement, or that the sensing method corresponding to the second information is speed measurement, or that the second information is data used by the sensing signal receiver and the sensing signal transmitter when performing speed measurement.

[0155] Optionally, if the second information is related to a sensing method, the type of the second information can also be used to indicate the sensing method associated with the second information. For example, if the second information is used for ranging (i.e., the second information is related to ranging), the type of the second information is used to indicate that the sensing method is ranging; or, if the second information is used for angle measurement (i.e., the second information is related to angle measurement), the type of the second information is used to indicate that the sensing method is angle measurement; or, if the second information is used for speed measurement (i.e., the second information is related to speed measurement), the type of the second information is used to indicate that the sensing method is speed measurement.

[0156] Step S302: The first device sends second information to the second device, wherein the first information and / or the second information are sent via broadcast.

[0157] Correspondingly, the second device receives the second information sent from the first device.

[0158] In one implementation, the first device can send a second message, which includes second information, and this second message is a broadcast message. That is, the aforementioned second information can be carried within the broadcast message, or in other words, the first device broadcasts the second information. It should be understood that the first message and the second message are two different broadcast messages.

[0159] For example, the first device broadcasts first information via the aforementioned first message and sends second information to the second device (non-broadcast transmission). In another example, the first device sends first information to the second device (non-broadcast transmission) and broadcasts second information via the aforementioned second message. Yet another example, the first device broadcasts first information via the aforementioned first message and broadcasts second information via the aforementioned second message. It should be noted that this application does not limit the method by which the first device determines whether to broadcast the first information or / or the second information.

[0160] For example, the second information can be a separate information block or an information block in an SIB message. This application does not limit the location or name of the second information.

[0161] Optionally, the first device may broadcast the second information, or the second device may send the second information to the first device upon request. For example, the second device may send a fourth information to the first device, which is used to request the second information. The first device sends the second information based on the fourth information. This application does not limit this.

[0162] In one implementation, the second device receives the second information based on the scheduling information of the second information.

[0163] For example, taking the scheduling information of the second information as including the type of the first indication information and the broadcast status of the first indication information, assuming that the broadcast status of the first indication information is "broadcasting", then the second device can obtain the broadcast message of the first device and obtain the first indication information from the broadcast message; assuming that the broadcast status of the first indication information is "provided when requested by the second device", then the second device can send a first request to the first device, the first request being used to request the provision of the first indication information, and then the second device can receive the first indication information from the first device.

[0164] The first and second information are described below by way of example using Tables 1 to 3. For ease of understanding, the second information will be referred to as sensing system information, the first information as sensing system information scheduling information, the scheduling period of the second information as sensing system information transmission information, the broadcast status of the second information as sensing system information transmission period, and the type of the second information as sensing system information type.

[0165] In this application, the aforementioned sensing system information can be carried in a broadcast message (such as system information). For ease of description, this application refers to the system information used to broadcast the aforementioned sensing system information as a position system information block (sensingSIB).

[0166] It should be understood that the sensing system information block is used to transmit actual sensing system information, such as sensing signal configuration information (e.g., the sensing system information indicated by sensingSibType2-1 and sensingSibType3-1 in Table 2), sensing target area configuration information (e.g., the sensing system information indicated by sensingSibType1-1 in Table 2), and TRP parameter information (e.g., the sensing system information indicated by sensingSibType2-2 and sensingSibType2-3 in Table 2), etc. For example, the sensing system information contained in each sensing system information block may correspond to the sensing information types in Table 1, and each sensing system information block may contain Table 2 and / or Table 3.

[0167] Table 1 provides an example of the scheduling information for the sensing system.

[0168] Table 1: Scheduling Information for Sensing System

[0169] As shown in Table 1, the scheduling information for sensing system information can include three fields, which indicate the transmission period, broadcast status, and type of sensing system information, respectively. For example, the scheduling information for sensing system information can be SIB.

[0170] The transmission period of the sensing system information defines the transmission cycle of the sensing system information. For example, the transmission period of the sensing system information can be in units of radio frames. For instance, rf8 means transmission once every 8 radio frames, rf16 means transmission once every 16 radio frames, and so on. This periodicity determines how often the UE needs to receive sensing system information.

[0171] The broadcast status of the sensing system information is used to indicate whether the sensing system information is being broadcast. For example, if the broadcast status of the sensing system information is set to broadcasting, it means that the sensing system information is being broadcast; if the broadcast status of the sensing system information is set to notBroadcasting, it means that the sensing system information is not provided through periodic broadcasting, but only when requested by the UE. Here, the broadcast status of the sensing system information being set to broadcasting (or status 1) is an example of the second information being broadcast, and the broadcast status of the sensing system information being set to notBroadcasting (or status 2) is an example of the second information being provided when requested by the second device.

[0172] The types of sensing system information include the types of sensing system information contained in the current system message (or sensing information types).

[0173] Optionally, the types of information in the sensing system can be classified according to sensing modes and sensing methods, or in other ways, such as specifically according to sensing services. Sensing services may include environmental reconstruction, target tracking, etc. This application does not limit this.

[0174] Optionally, the sensing system information type can also be used to indicate the sensing mode. For example, the sensing system information type can be represented by sensingSibType ij, where i indicates the sensing mode. In Table 2, i = 0 indicates BS Monostatic, and i = 1 indicates BS-BS Bistatic.

[0175] Referring to Table 2, which exemplarily illustrates the types of sensing system information based on sensing modes, the sensing modes include BS Monostatic, BS-BS Bistatic, BS-UE Bistatic, UE-BS Bistatic, UE Monostatic, and UE-UE Bistatic. The first column of Table 2 represents the sensing mode, the second column represents the type of sensing system information corresponding to that sensing mode, and the third column indicates the specific content of the sensing system information indicated by the type of sensing system information.

[0176] Table 2: Types of Perceptual Information Based on Perceptual Pattern Classification

[0177] Table 2 provides an example showing that: the type of the first indication information can be sensingSibType0-1, the type of the second indication information can be sensingSibType0-2, the type of the third indication information can be sensingSibType1-1, the type of the fourth indication information can be sensingSibType1-2, the type of the fifth indication information can be sensingSibType1-3, the type of the sixth indication information can be sensingSibType1-4, the type of the seventh indication information can be sensingSibType2-1, and the type of the eighth indication information can be sensingSibType2-5. Alternatively, the type of the ninth indication information can be sensingSibType3-4, the type of the tenth indication information can be sensingSibType3-3 or sensingSibType4-2, the type of the eleventh indication information can be sensingSibType4-3, the type of the twelfth indication information can be sensingSibType2-2, the type of the thirteenth indication information can be sensingSibType2-3, the type of the fourteenth indication information can be sensingSibType2-4, and the type of the fifteenth indication information can be sensingSibType3-2.

[0178] Optionally, the types of sensing system information in Table 2 can also be used to indicate sensing modes. For example, sensingSibType0-1 to sensingSibType0-2 and sensingSibType1-1 to sensingSibType1-4 can also be used to indicate that the sensing mode corresponding to their respective sensing system information is BS Monostatic or BS-BS Bistatic; as another example, sensingSibType2-1 to sensingSibType2-5 can also be used to indicate that the sensing mode corresponding to their respective sensing system information is BS-UE Bistatic; as another example, sensingSibType3-1 to sensingSibType3-5 can also be used to indicate that the sensing mode corresponding to their respective sensing system information is UE-BS Bistatic; as another example, sensingSibType4-1 to sensingSibType4-3 can also be used to indicate that the sensing mode corresponding to their respective sensing system information is UE Monostatic or UE-UE Bistatic.

[0179] It should be noted that this application can also use a separate instruction to indicate the perception mode; that is, the first to fifteenth instruction information mentioned above do not indicate the perception mode.

[0180] Optionally, the sensing system information type can also be used to indicate the sensing method. For example, the sensing system information type can be represented by sensingSibType ab, where a indicates the sensing method and b indicates the sensing system information type.

[0181] Referring to Table 3, which exemplarily illustrates the types of sensing system information categorized by sensing method, the sensing methods include ranging, angle measurement, and velocity measurement. Understandably, the system information differs depending on the sensing method. For example, ranging requires providing the sensing AOI (Area of ​​Interest), while velocity measurement requires providing the tracking target ID. Furthermore, different sensing methods have different requirements for time and phase synchronization. For instance, ranging (Range-based) requires time synchronization to measure signal propagation time, angle measurement (Angle-based) requires phase synchronization to measure phase difference, and velocity measurement (Velocity-based) requires both time and phase synchronization. For example, angle measurement can refer to measuring the angle information of the sensing target relative to the sensing node; ranging can refer to measuring the distance information of the sensing target from the sensing node; and velocity measurement can refer to measuring the velocity information of the sensing target.

[0182] Table 3: Types of Perceptual Information Classified by Perception Methods

[0183] For a detailed explanation of each indicator in the third column of Table 3, please refer to Table 2.

[0184] Table 3 illustrates, for example, that the type of the third indication information can be sensingSibType1-1 or sensingSibType2-1, the type of the fourth indication information can be sensingSibType3-1, the type of the seventh indication information can be sensingSibType1-2, the type of the twelfth indication information can be sensingSibType1-3, the type of the fourteenth indication information can be sensingSibType1-4 or sensingSibType2-3, the type of the seventh indication information can be sensingSibType2-2, the type of the eighth indication information can be sensingSibType2-6 or sensingSibType3-4, the type of the tenth indication can be sensingSibType2-5, the type of the twelfth indication information can be sensingSibType1-3 or sensingSibType2-3 or sensingSibType3-2, the type of the thirteenth indication information can be sensingSibType2-4, and the type of the fourteenth indication information can be sensingSibType3-3 or sensingSibType3-4.

[0185] Optionally, the types of sensing system information in Table 3 can also be used to indicate sensing methods. For example, sensingSibType1-1 to sensingSibType1-4 can also be used to indicate that the sensing method corresponding to their respective sensing system information is Range-based; sensingSibType2-1 to sensingSibType2-6 can also be used to indicate that the sensing method corresponding to their respective sensing system information is Angle-based; and sensingSibType3-1 to sensingSibType3-4 can also be used to indicate that the sensing method corresponding to their respective sensing system information is Velocity-based.

[0186] It should be noted that this application may also indicate the sensing method through independent indication information; that is, the first to fifteenth indication information mentioned above do not indicate the sensing method.

[0187] The method embodiments shown in Figure 3 above include many possible implementation schemes. Some of these implementation schemes will be illustrated below with reference to Figures 4 to 6. It should be noted that related concepts, operations or logical relationships not explained in Figures 4 to 6 can be referred to the corresponding descriptions in the embodiments shown in Figure 3.

[0188] In this application, the embodiments shown in Figures 4 to 6 can be used as a single embodiment, and the embodiments shown in Figures 4 to 6 can all be independent of the technical solution in Figure 3; some steps in the embodiments shown in Figures 4 to 6 can also be used as a single embodiment.

[0189] Figure 4 is a flowchart illustrating another communication method provided in an embodiment of this application.

[0190] This application uses an example where the first device is a base station and the second device is a UE to provide a detailed description of the communication method provided in this application. It should be noted that this application embodiment is also applicable to sidelink scenarios, where the first device and the second device are different UEs. For a specific implementation, please refer to Figure 4; further details will not be provided here.

[0191] In the embodiments of this application, dashed arrows represent optional steps, such as step S403, which is an optional step.

[0192] As shown in Figure 4, the method may include steps S401-S405:

[0193] S401: The base station sends a broadcast message.

[0194] For example, the broadcast message can be an SIB message.

[0195] S402: The UE obtains scheduling information of the sensing system based on broadcast messages.

[0196] In one implementation, the UE can retrieve whether the broadcast message contains scheduling information for the sensing system. If the broadcast message does not contain scheduling information for the sensing system, the process is stopped; if the broadcast message contains scheduling information for the sensing system, step S402 or S403 is executed.

[0197] Optionally, the UE can determine whether to execute step S403 or S404 based on the scheduling information of the sensing system information. For example, when the scheduling information of the sensing system information includes the broadcast status of the sensing system information, if the broadcast status of the sensing system information is "provided upon request", the UE can execute step S403; if the broadcast status of the sensing system information is "broadcasting", the UE can execute step S404 to obtain the sensing system information from the broadcast message.

[0198] S403: The UE requests sensing system information from the base station.

[0199] S404: The base station sends sensing system information to the UE.

[0200] S405: The UE performs perception based on information from the perception system.

[0201] In one implementation, the UE can first determine whether the received sensing system information is available. If it is available, the UE performs sensing based on the sensing system information.

[0202] For example, in both BS Monostatic and BS-BS Bistatic modes, if the sensing system information in step S404 is auxiliary data related to information such as the sensing AOI and / or target ID, sensing result, and sensing quality, then in step S405, the UE can determine whether the aforementioned auxiliary data is available based on the received sensing system message. If it is available, the UE can directly use the auxiliary data provided in the BS system message. This application does not limit the method by which the UE determines whether the aforementioned auxiliary data is available. For example, if the aforementioned auxiliary data includes the sensing AOI, then the UE determines whether the sensing AOI contains the area that the UE wants to sense. If the sensing AOI contains the area that the UE wants to sense, then the UE determines that the aforementioned auxiliary data is available; otherwise, it considers the auxiliary data unavailable.

[0203] Figure 5 is a flowchart illustrating another communication method provided in an embodiment of this application. It should be noted that this embodiment is also applicable to sidelink scenarios, where the first device and the second device are different UEs. For specific implementation details, please refer to Figure 5; further details will not be provided here.

[0204] This application uses an example where the first device is a base station, the second device is a UE, and the sensing mode is BS Monostatic or BS-BS Bistatic to provide a detailed description of the communication method provided in this application.

[0205] In the embodiments of this application, dashed arrows represent optional steps, such as step S503, which is an optional step.

[0206] As shown in Figure 5, the method may include steps S501-S508:

[0207] S501: The base station sends a broadcast message.

[0208] S502: The UE obtains scheduling information for the sensing system based on broadcast messages. S503: The UE requests sensing system information from the base station.

[0209] S504: The base station sends sensing system information to the UE.

[0210] The specific content of steps S501 to S504 can also be exemplified by referring to steps S401 to S404 above.

[0211] S505: The UE determines whether the base station supports sensing based on the sensing system information.

[0212] For example, the sensing system information includes first indication information, and the scheduling information of the sensing system information includes the type, broadcast status and transmission period of the first indication information. Then, the UE can obtain the first indication information based on the scheduling information. If the first indication information is used to indicate that the base station supports sensing, the UE determines that the base station supports sensing and the UE executes step S506. If the first indication information is used to indicate that the base station does not support sensing, the UE determines that the base station does not support sensing and the UE stops the process.

[0213] In another example, the sensing system information includes first indication information and second indication information. If the first indication information indicates that the base station supports sensing and the second indication information indicates that the base station has a sensing result, or if the first indication information indicates that the base station does not support sensing and the second indication information indicates that the base station has a sensing result, or if the first indication information indicates that the base station supports sensing and the second indication information indicates that the base station has no sensing result, then the UE can execute step S506. If the first indication information indicates that the base station does not support sensing and the second indication information indicates that the base station has no sensing result, then the UE can stop the process.

[0214] S506: The UE sends a first request to the base station, which is used to request the base station to provide sensing services.

[0215] The first request is used to indicate the sensing requirements, such as sensing AOI / target ID, sensing performance requirements, etc.

[0216] S507: The base station performs sensing based on the first request and obtains the first sensing result.

[0217] For example, the first request is used to indicate the sensing requirement, and the base station performs sensing based on the sensing requirement to obtain the first sensing result.

[0218] S508: The base station sends the first sensing result to the UE.

[0219] It should be noted that the execution steps of step S507 are not limited in this embodiment. For example, if the base station has generated a first sensing result before step S506, then step S507 is performed before step S506; or, for example, step S507 is performed after step S506. For instance, the sensing system information includes second indication information. If the second indication information is used to indicate that the base station has a sensing result, then the UE can execute step S506, and correspondingly, the base station executes step S508; if the second indication information is used to indicate that the base station has no sensing result, then step S506 is executed, and correspondingly, the base station executes step S507.

[0220] Figure 6 is a flowchart illustrating another communication method provided in an embodiment of this application. It should be noted that this embodiment is also applicable to sidelink scenarios, where the first device and the second device are different UEs. For specific implementation details, please refer to Figure 6; further elaboration is not provided here.

[0221] This application uses a first device as a base station and a second device as a UE as an example to provide a detailed description of the communication method provided in this application.

[0222] As shown in Figure 6, the method may include steps S601-S604:

[0223] S601: The base station determines whether the sensing system information has changed.

[0224] Optionally, the base station can periodically or in real time detect whether the sensing system information has changed.

[0225] S602: The base station sends a change indication to the UE, which is used to indicate that the sensing system information has changed.

[0226] In one implementation, the base station sends sensing system information to the UE, and when it determines that the sensing system information has changed, it can send the aforementioned change indication to the UE. For example, the base station can broadcast the change indication.

[0227] Step S602 can be an optional step. For example, when the base station determines that the sensing system information has changed, it may not send the above-mentioned change indication, but directly send the changed sensing system information to the UE.

[0228] S603: The base station sends the modified sensing system information to the UE.

[0229] In one implementation, the base station can send the modified sensing system information to the UE after sending the aforementioned change instruction.

[0230] In other embodiments of this application, the base station may also send the above-mentioned change instruction and the changed perception system information to the UE at the same time, such as the change instruction and the changed perception system information being carried in the same message (such as a broadcast message).

[0231] S604: The UE performs perception based on the modified perception system information.

[0232] In some embodiments of this application, the base station can broadcast the aforementioned change instruction and the scheduling information of the sensing system information, and then broadcast the changed sensing system information. The UE can then obtain the changed sensing system information based on the change instruction and the scheduling information of the sensing system information.

[0233] The foregoing details the method provided in this application. To facilitate the implementation of the above-described solutions in the embodiments of this application, corresponding apparatus or devices are also provided in the embodiments of this application.

[0234] This application divides the first device and the second device into functional modules according to the above method embodiments. For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing module. The integrated modules can be implemented in hardware or as software functional modules. It should be noted that the module division in this application is illustrative and only represents one logical functional division; other division methods may be used in actual implementation. The communication device of the embodiment of this application will be described in detail below with reference to Figures 7 to 9.

[0235] Referring to Figure 7, which is a schematic diagram of a communication device provided in an embodiment of this application, the communication device may include a transceiver unit 10 and a processing unit 20.

[0236] In some embodiments of this application, the communication device may be the second device shown above, or a chip or circuit disposed in the second device. That is, the communication device may be used to perform the steps or functions performed by the second device in the method embodiments described above.

[0237] In one design, the transceiver unit 10 is used to: send first information, the first information being scheduling information for indicating second information, the second information being sensing auxiliary data; and send second information, wherein the first information and / or the second information are sent via broadcast.

[0238] In one possible implementation, the second information is perception assistance data, which includes perception configuration information and / or the perception capabilities of the first device.

[0239] In one possible implementation, the transceiver unit 10 is specifically used to: send a first message, the first message including first information, and the first message being a broadcast message.
