Description

A communication method and related apparatus

[0001] This application claims priority to Chinese Patent Application No. 202411522497.3, filed on October 28, 2024, entitled "A Communication Method and Related Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more particularly to a communication method and related apparatus. Background Technology

[0003] In the evolution of communication technology, integrated sensing and communication (ISAC) technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. ISAC technology can also be called sensing technology. The core idea of ​​this technology is to add sensing capabilities to mobile communication networks, building the ability to detect, track, and image targets, thus integrating communication and sensing capabilities into a single network.

[0004] In sensing technology, sensing modes are generally divided into two types: monostatic sensing and bistatic sensing. Monostatic sensing, also known as single-station sensing, refers to a single device that transmits and receives the measurement signal. In terms of signal transmission, the sensing station both sends and receives the signal reflected from the obstacle surface (also known as the echo signal). Therefore, monostatic sensing is also called the self-transmitting and self-receiving mode. Bistatic sensing, on the other hand, involves two different devices that transmit and receive the measurement signal. In terms of signal transmission, sensing station A sends the measurement signal, and the signal reflected from the obstacle surface is received by sensing station B. Therefore, bistatic sensing is also called the A-transmitting and B-receiving mode.

[0005] As described above regarding the sensing modes, the transmitting and receiving ends of the measurement signals differ under different sensing modes. Each sensing mode requires separate configuration of the measurement signals. Therefore, it is impossible to uniformly control and flexibly schedule the measurement signals, thus limiting the accuracy of sensing measurements and increasing communication overhead. Furthermore, the reporting method for measurement signals under different sensing modes also requires separate configuration. Therefore, it is impossible to uniformly control the reporting of measurement signals, further limiting the accuracy of sensing measurements and increasing communication overhead. Summary of the Invention

[0082] References to "one embodiment" or "some embodiments" as described in this application mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0083] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. "At least one 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. Where a, b, and c can be single or multiple.

[0084] First, the communication system involved in the embodiments of this application is introduced. This application can be applied to long-term evolution (LTE) systems, new radio (NR) systems, or future communication systems after 5G. The communication system includes at least one network device and / or at least one terminal device.

[0085] Figure 1 is a schematic diagram of the architecture of the communication system 1000 used in the embodiments of this application.

[0086] As shown in Figure 1, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one network-side device (the network-side device in this embodiment can also be understood as a network device, such as 110a and 110b in Figure 1, which can also be called an access network device), and at least one terminal (which can also be understood as the terminal device described above, such as 120a-120j in Figure 1). Furthermore, the network device (or wireless network device) can be a macro base station (as shown in Figure 1, 110a), a micro base station or an indoor station (as shown in Figure 1, 110b), a relay node or a donor node, etc. It is understood that all or part of the functions of the network device 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). The embodiments of this application do not limit the specific technology or specific device form adopted by the wireless network device.

[0087] For ease of description, the communication system illustrated in Figure 1 is described using the network device as a base station and the terminal device as a terminal. It is understood that if the communication system includes an integrated access and backhaul (IAB) network, the base station can be an IAB node. It should be noted that in the embodiments of this application, the base station and the network device can be interchanged.

[0088] In this application, the base station and the terminal can be fixed or mobile. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted, on water, or in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base station and the terminal.

[0089] The roles of base station and terminal can be relative. For example, the helicopter or drone 120i in Figure 1 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. Alternatively, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base station and terminal can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with base station functions, and 120a-120j in Figure 1 can be called communication devices with terminal functions.

[0090] 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 achieved 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.

[0091] Figure 2a is a schematic diagram of a communication system in an embodiment of this application. Referring to Figure 2a, the communication system includes user equipment (UE), radio access network (RAN) equipment (or simply network equipment), access and mobility management function (AMF), user plane function (UPF), unified data management (UDM), network data analytics function (NWDAF), location management function (LMF), policy control function (PCF), or network function (NEF).

[0092] The communication system also includes a sensing function (SF), which can establish connections with other core network functions, such as UPF, AMF, UDM, NWDAF, LMF, PCF, or NEF. The sensing function is responsible for configuring how sensing devices perform sensing measurements or interact with sensing requirements. It can also process sensing data. The sensing device can be either a RAN or a UE, and the sensing data can be, for example, data or information related to sensing measurements.

[0093] In one example, the LMF is used to calculate the location of the terminal device. The SF can store an environmental map, enabling environmental map reconstruction, and it interacts with the LMF to exchange environmental, measurement, and other information.

[0094] The name of the sensing function may change as the communication system evolves. Any functional network element with a name similar to SF can be understood as the SF of this application and is applicable to the methods provided in this application. For example, SF can also be a communication sensing function, sensing management function entity, sensing function network element, sensing network element, sensing server, or other names. This application does not limit the name of SF. The following embodiments mainly use the description of SF to introduce the execution operation of this functional network element. The interaction between SF and RAN or UE can be transmitted through AMF or directly. For example, sensing data acquired by RAN or UE can be transmitted to SF via control plane or user plane. Specifically, user plane can be forwarded from RAN or UE to SF via UPF, or RAN or UE can transmit directly to SF.

[0095] Figure 2b is another schematic diagram of the communication system in an embodiment of this application. Referring to Figure 2b, a sensing unit (SU) is added to the network device side of the communication system. This SU can be used to perform sensing-related functions, including but not limited to: the SU interacting with the SF to sense requirements, and the SU interacting with the core network equipment, RAN, or UE to sense data. The core network equipment is, for example, an AMF or UPF. For example, the RAN includes a centralized unit (CU) or a distributed unit (DU).

[0096] In one example, the UE outputs a measurement signal report to the RAN. The measurement signal report can be passed from the UE to the DU, then from the DU to the CU, and finally from the CU to the SU on the RAN side; or the measurement signal report can be passed from the UE to the DU and then directly from the DU to the SU; or the UE can directly pass the measurement signal report to the SU.

[0097] In another example, the RAN outputs configuration information to the UE. The configuration information can be passed from the SU on the RAN side to the CU, then from the CU to the DU, and finally from the DU to the UE; or the configuration information can be passed from the SU to the DU and then directly from the DU to the UE; or the SU can directly pass the configuration information to the UE.

[0098] The name of the sensing unit may change as the communication system evolves. Any functional network element with a name similar to SU can be understood as SU in this application and is applicable to the method provided in this application. For example, SU can also be a sensing computing unit, sensing computing module, sensing module, sensing computing board, computing device, or other names. This application does not limit the name of SU.

[0099] The sensing unit can be independent of the network device; for example, it can be deployed in an edge computing device, or it can be an external service board of the network device. Alternatively, the sensing unit can be co-located with the network device, for example, it can be a functional unit or module within the network device.

[0100] 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, 5G communication systems, and communication systems beyond the 5th generation. For example, future communication systems. For example, 4th generation communication systems may include Long Term Evolution (LTE) communication 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, or vehicle-to-everything (V2X) communication systems.

[0101] The following describes the terminal equipment, network equipment, sensing management function, and positioning management function involved in this application.

[0102] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises equipment (CPE), etc., refers to devices that include wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. 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 functions. The terminal device usually contains a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0103] 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, or control unit in the device or apparatus shown above; this application does not limit the specific application. It should also be noted that in this application, the term "terminal device" can refer to the terminal device itself, or to the chip, functional module, or integrated circuit within the terminal device that performs the method provided in this application; this application does not limit the specific application. A network device is an apparatus deployed in a wireless access network to provide wireless communication functions for terminal devices. A network device can connect a terminal device to a radio access network (RAN) node in a wireless network, and can also be referred to as a network device, RAN entity, access node, network node, or communication device, etc.

[0104] Specifically, network equipment can be network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, 4G communication systems, 5G communication systems, or future communication systems. Network equipment can also be network equipment in Open RAN (ORAN) or Cloud Radio Access Network (CRAN). Alternatively, network equipment can also be network equipment in a communication system resulting from the integration of two or more of the above communication systems.

[0105] Network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), access point (AP) in wireless fidelity (WIFI) systems, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenarios, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), etc., and can also be network equipment in 5G mobile communication systems. For example, next-generation base station (gNB) in NR systems, TRP, TP; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or, network equipment can also be network nodes constituting a gNB or transmission point. Examples include centralized unit (CU), distributed unit (DU), centralized unit control plane (CU-CP), centralized unit user plane (CU-UP), or radio unit (RU). CUs and DUs can be separate entities or included in 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, network equipment in V2X technology can be roadside units (RSUs). It should be understood that the aforementioned TRP can be a device or module located on the network side of the communication system and possessing corresponding communication functions. The TRP typically contains communication modules, circuits, or chips that perform the corresponding communication functions. The TRP can also be configured with program instructions for the corresponding communication functions.

[0106] 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 Open Access Network (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), CU-CP can also be called an open centralized unit control plane (O-CU-CP), CU-UP can also be called an open centralized unit user plane (O-CU-UP), and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations on these details. 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.

[0107] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 below.

[0108] Table 1

[0109] It should be noted that in the ORAN system, the network device in this application can be one or more network elements listed in Table 1 above.

[0110] The architecture of the CU and DU of a network device is described below. A network device includes at least one CU and at least one DU. Optionally, the network device may also include at least one RU.

[0111] The following example uses a network device consisting of a CU and a DU. The CU has some core network functions and can include CU-CP and CU-UP. The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU may be configured to implement the Packet Data Convergence Protocol (PDCP) layer and above (e.g., RRC and / or SDAP layers). The DU may be configured to implement protocol layers below the PDCP layer (e.g., RLC, MAC, and / or physical (PHY) layers). Alternatively, the CU may be configured to implement protocol layers above the PDCP layer (e.g., RRC and / or SDAP layers), and the DU may be configured to implement protocol layers below the PDCP layer (e.g., RLC, MAC, and / or PHY layers).

[0112] If a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, if a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0113] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF in a 5G system. The AMF 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.

[0114] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and inputting data in terminal devices.

[0115] Optionally, the ORAN architecture also includes a RAN Intelligent Controller (RIC) module.

[0116] It should be noted that 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, or control unit in the aforementioned device or apparatus; this application does not impose any specific limitation. It should also be noted that in this application, the term "network equipment" can refer to the network equipment itself, or to the chip, functional module, or integrated circuit within the network equipment that performs the methods provided in this application; this application does not impose any specific limitation.

[0117] Secondly, some technical concepts involved in the embodiments of this application will be introduced.

[0118] 1. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority, or importance of multiple objects.

[0119] 2. In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly via the air interface or sending indirectly via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY via the air interface or receiving indirectly from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0120] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0121] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0122] In this application embodiment, "send" can be replaced with "output" and "receive" can be replaced with "input". This application embodiment does not limit this.

[0123] 3. In the embodiments of this application, "instruction" can include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the output party of the instruction information, the instruction information can be used to indicate the information to be instructed; for the input party of the instruction information, the instruction information can be used to determine the information to be instructed.

[0124] 4. Environment and environmental information.

[0125] The environment can also be referred to as the scene. In the embodiments of this application, the environment refers to the environment in which the transmitter or receiver is located (or situated). The environment in which the transmitter is located can be an environment determined with the transmitter's position as a reference point; similarly, the environment in which the receiver is located can be understood as an environment determined with the receiver's position as a reference point. In fact, both the environment in which the transmitter and the environment in which the receiver are located can include the transmitter and the receiver. The environment can be used to assist in locating the transmitter and the receiver. In addition to the transmitter and the receiver, the scene can also include obstacles.

[0126] Information used to indicate the environment is called environmental information. Environmental information can also be called environmental parameter information, or environmental parameter set information, etc. Environmental information indicates the environment in which the transmitter or receiver is located. Environmental information indicates obstacles in the environment. Environmental information includes at least one of the following: the number of obstacles, their location, shape, or material properties. The content of obstacles can refer to the obstacle content discussed above; repeated descriptions will not be listed again. Optionally, environmental information indicates at least one of the following: the outline and material of buildings and vegetation, the outline and location of vehicles, the location of pedestrians, or the distribution of crowds.

[0127] Environmental information can take the form of environmental map information or environmental point cloud information (such as two-dimensional, three-dimensional, or higher-dimensional point cloud information). Map information, such as a building map, can contain the coordinates of multiple edges of buildings, thus indicating the location, shape, and size of obstacles in the environment. Three-dimensional point cloud information includes, for example, a large number of points, each containing a three-dimensional coordinate and other attributes, such as point cloud intensity information or point cloud type information, indicating the object type (or material) corresponding to the point cloud.

[0128] 5. Environmental perception.

[0129] With the rapid development of wireless communication technology, base stations, as core components of networks, are constantly expanding their functions and application scenarios. In recent years, the technology of using base stations for environmental sensing has gradually attracted attention. This technology is based on the interaction between the base station and its surrounding environment, and achieves the perception and monitoring of the surrounding environment by collecting and analyzing the signals received by the base station.

[0130] In the field of environmental sensing, traditional methods typically rely on specialized sensors and equipment, such as cameras, radar, or infrared detectors. However, these methods have several drawbacks, including high cost, difficult deployment, and susceptibility to weather conditions. In contrast, utilizing base stations for environmental sensing offers numerous advantages.

[0131] Base stations offer extensive coverage. As the infrastructure of wireless communication networks, base stations typically cover entire cities or specific areas. This means that using base stations for environmental sensing enables real-time monitoring of large areas, providing valuable data support for urban planning, traffic management, disaster early warning, and other fields. Secondly, base stations are continuously online. They need to provide communication services to users 24 hours a day, so they are always operational. This allows for real-time, continuous data collection and analysis for environmental sensing, enabling timely detection and handling of environmental problems. Furthermore, using base stations for environmental sensing can reduce costs. Since base stations are already widely deployed in cities, there is no need to install a large number of additional sensors and equipment. Simply upgrading and modifying existing base stations is sufficient to achieve environmental sensing and monitoring. This not only saves significant investment costs but also avoids redundant construction and resource waste.

[0132] 6. Sensing technology.

[0133] Sensing technology refers to the use of communication networks to detect, track, and image obstacles. The underlying principles of sensing technology differ somewhat from those of communication technology. Communication technology involves the transmitter modulating information onto radio waves and sending it to the receiver, which then demodulates the signal to obtain the information. Sensing technology, however, requires the transmitter to send radio waves in a specific direction. When these radio waves strike the surface of an obstacle, they are reflected, and the receiver receives and processes these reflected waves to obtain information such as the obstacle's shape, size, location, material, speed, and type.

[0134] Sensing technologies can generally be divided into two types based on their modes: single-base sensing and dual-base sensing. In single-base sensing, the transmitting and receiving ends of the measurement signal are the same device. In terms of the measurement signal flow, the sensing station must both send the measurement signal and receive the signal reflected from the surface of the obstacle (also known as the echo signal). Therefore, the single-base sensing mode is also called the self-transmitting and self-receiving mode.

[0135] As shown in Figure 3a, which is a schematic diagram of a single-base sensing scenario, dual-base sensing involves two different devices that transmit and receive the measurement signal. In terms of the signal flow, after sensing station A transmits the measurement signal, the signal reflected from the obstacle surface is received by sensing station B. Therefore, dual-base sensing is also called the A-transmit B-receive mode, as shown in Figure 3b, which is a schematic diagram of a dual-base sensing scenario.

[0136] For ease of understanding, please refer to Figure 3c, which is a schematic diagram of a sensing scenario in an embodiment of this application. During the communication between the network device and the terminal device in Figure 3c, the network device can also sense objects that do not have communication capabilities, such as the car and the user in Figure 3c.

[0137] Furthermore, the sensing scenario illustrated in Figure 3c can be further subdivided into various sub-scenarios. For example, the sensing scenario illustrated in Figure 3d takes a network device as a base station and a terminal device as a user equipment (UE). Figure 3d is a schematic diagram of another sensing scenario in this application embodiment. The sensing scenario can specifically include: (1) The base station sends a measurement signal and receives the echo signal of the measurement signal itself; this scenario is also called the base station's self-transmission and self-reception scenario; (2) The UE sends a measurement signal and receives the echo signal of the measurement signal itself; this scenario is also called the UE's self-transmission and self-reception scenario; (3) Base station A sends a measurement signal, and base station B receives the echo signal of the measurement signal; base station A and base station B are different base stations; (4) UE A sends a measurement signal, and UE B receives the echo signal of the measurement signal; UE A and UE B are different UEs; (5) The base station sends a measurement signal, and the UE receives the echo signal of the measurement signal; (6) The UE sends a measurement signal, and the base station receives the echo signal of the measurement signal. The above scenarios (3) to (6) can also be called self-transmission and self-reception scenarios.

[0138] As described above, the transmitting and receiving ends of the measurement signals differ under different sensing modes. Each sensing mode requires its own measurement signal configuration. Therefore, it is impossible to uniformly control and flexibly schedule the measurement signals, which limits the accuracy of sensing measurements and increases communication overhead.

[0139] Based on this, embodiments of this application propose a communication method and related apparatus. A first apparatus acquires configuration information, which indicates a sensing mode and the resources of the measurement signal corresponding to that sensing mode. The first apparatus outputs a measurement signal, which is carried on the resources of the measurement signal corresponding to the sensing mode. Through the configuration information, measurement signals suitable for different sensing modes can be flexibly configured, enabling unified scheduling of measurement signals under different sensing modes, thereby improving the accuracy of sensing measurements and reducing the communication overhead of sensing measurements.

[0140] First, the communication system involved in the embodiments of this application is introduced. Please refer to Figure 4a, which is a schematic diagram of the structure of a communication system involved in the embodiments of this application. The communication system proposed in this application includes: a first device, a second device, and a third device. The second device outputs configuration information to the first and third devices. The first device outputs a measurement signal to the third device according to the configuration information. The third device inputs the measurement signal from the first device according to the configuration information. The first device, second device, and third device described above have various possible implementations, which will be further explained below with reference to the accompanying drawings.

[0177] It should be noted that the measurement signal input to the aforementioned network device or terminal device can be the measurement signal itself, or it can be the echo signal after the measurement signal has been scattered, reflected, refracted and / or diffracted by an obstacle. This application embodiment does not limit this.

[0178] Based on the aforementioned communication system and sensing mode, the method embodiment of this application will be described next. Please refer to Figure 6a, which is a schematic flowchart of an embodiment of the communication method in this application. The communication method proposed in this application includes:

[0179] 601. The second device sends configuration information to the first device, indicating the sensing mode and the resources for the report corresponding to the sensing mode.

[0180] In step 601, the first device determines the resources of the report and the sensing mode corresponding to the report based on the configuration information. The report refers to a measurement signal report, and the configuration information can also be called measurement signal report configuration information (e.g., "CSRS-ReportConfig"). The first device can also obtain the configuration information of the measurement signal (which can also be called measurement signal resource configuration information). The configuration information of the measurement signal indicates the sensing mode and the resources of the measurement signal corresponding to the sensing mode. Then, the first device performs the sensing measurement corresponding to the sensing mode based on the configuration information of the measurement signal. Specifically, the first device outputs the measurement signal based on the resources of the measurement signal. Exemplarily, the measurement signal in this embodiment can be a cooperative sensing reference signal (CS-RS). It should be noted that the measurement signal in this embodiment can also be other types of reference signals, and this embodiment does not limit this. Then, the first device determines the resources of the report based on the configuration information of the report, and then the first device receives the report on the resources of the report. The report corresponds to the measurement signal and includes the measurement result of the measurement signal.

[0181] Optionally, the configuration information indicating the perception mode and the resources of the report corresponding to the perception mode can be replaced with: the configuration information indicating the resources of the report and the perception mode to which the report applies; or, the configuration information indicating the resources of the report and the perception mode corresponding to the report.

[0182] It should be noted that the sensing mode indicated by the configuration information of the measurement signal is consistent with the sensing mode indicated by the configuration information of the corresponding report.

Non-periodic report sending means: sending the report once or more after sending a second activation command. Fixed-number repeated report sending means: repeatedly sending the report K times, where K is an integer greater than or equal to 1. For example, the relationship between the value of the report type information and the report sending method indicated by the report type information is shown in Table 4.

[0198] Table 5

[0199] Optionally, the sensed measurements included in the report (e.g., "reportQuantityForSensing") can also be indicated by flags to specify the exact measurements included in the report (e.g., "reportQuantity"). For example, a flag of 0 for "reportQuantityForSensing" indicates that "reportQuantity" does not include the measurement; a flag of 1 for "reportQuantityForSensing" indicates that "reportQuantity" includes SQI; and a flag of 2 for "reportQuantityForSensing" indicates that "reportQuantity" includes the measurements delay, doppler, and SQI.

[0201] 7. SQI Calculation Rules (e.g., "SQI-Table"): This information indicates the calculation rule number used to calculate the sensing quality indicator (SQI). This SQI calculation rule can also be called an SQI table. The third device sending the report determines the SQI of the measured signal according to the SQI calculation rule and reports the SQI of the measured signal in the report. The SQI calculation rule indicates that the first communication device supports W SQI calculation rules, where W is an integer greater than or equal to 1.

This time-domain resource configuration information is used to configure these resources, and the report is carried within them. These resources include, but are not limited to: frames, subframes, time slots, or orthogonal frequency division multiplexing (OFDM) symbols. Specifically, the report's time-domain resource configuration information includes one or more of the following:

[0208] 9-4. Fixed-number repetition parameter (e.g., "reportRepetitionNumber"), which indicates that the report will be resent K times when the report is sent in a fixed-number repetition mode. For example, the relationship between the value of the fixed-number repetition parameter and the number of times the report is resent is shown in Table 6.

[0214] 13. Frequency domain resource configuration information for the report (e.g., "reportFreqConfiguration"). The report's resources include its frequency domain resources. This information is used to configure the report's frequency domain resources, which are used to carry the report. These frequency domain resources include, but are not limited to, Physical Resource Blocks (PRBs), Resource Blocks (RBs), or frequency bands. Specifically, the report's frequency domain resource configuration information includes one or more of the following:

[0218] 13-4. Frequency domain resource information corresponding to the SQI (e.g., "SQI-FormatIndicator"), which indicates whether the reported SQI is a single-band SQI or a multi-subband SQI. For example, the relationship between the value of the fixed-number repetition parameter and the number of repetitions in the report is shown in Table 7.

[0220] For example, the length of the frequency domain resource information corresponding to SQI is 1 bit.

[0221] 14. Resource identification information for the measurement signal (e.g., "resouseForSensingMeasurement"), which indicates the resource of the measurement signal corresponding to this report. This information is used to associate the configuration information of the report with the configuration information of the measurement signal.

[0222] 15. A time series for sensing measurements (e.g., "timeRsetrictionForSensingMeasurement") that indicates the time-domain limitations of the measurement signal for sensing measurements.

[0223] 16. Antenna port indication information corresponding to the perceived quality indicator (SQI), wherein the antenna port indication information corresponding to the SQI is used to indicate the antenna port corresponding to the SQI, and the antenna port corresponding to the SQI is used to carry the measurement signal.

[0224] Second, the constraints between the above-mentioned types of information (or information elements) are introduced.

[0225] For ease of description, the following examples will be used to illustrate the following physical channels: Physical Downlink Shared Channel (PDSCH), Physical Channel 1: Physical Downlink Control Channel (PDCCH), Physical Channel 2: Physical Uplink Shared Channel (PUSCH), Physical Channel 3: Physical Uplink Control Channel (PUCCH), Physical Channel 4: Physical Side Link Shared Channel (PSSCH), Physical Channel 5: Physical Side Link Control Channel (PSCCH), Physical Channel 6: Physical Side Link Feedback Channel (PSFCH), Physical Channel 7: Independent RS on Crosslink, Physical Channel 8: Independent RS on Backhaul link, and Physical Channel 9: Xn interface.

[0226] In one example, the constraint relationships between perception mode type information, physical channel type information, and report type information are shown in Table 8.

[0227] Table 8

[0228] In one example, when the perception mode type information in the configuration information indicates perception mode 0, the physical channel type information in the configuration information is empty; the report type information in the configuration information indicates that the report transmission method is empty. In other words, when the configuration information indicates that the perception mode of the report is perception mode 0, the report is determined by the network device sending the measurement signal itself, so the network device does not need to transmit the report to other devices.

[0229] In another example, when the perception mode type information of the configuration information indicates perception mode 1, the physical channel type information of the configuration information indicates that the physical channel carrying the report includes one or more of the following: physical channel 7, physical channel 8, or physical channel 9; the report type information of the configuration information indicates that the output method of the report includes any one of the following: periodic report sending, semi-static report sending, non-periodic report sending, or report sending repeatedly a fixed number of times.

[0230] In another example, when the perception mode type information of the configuration information indicates perception mode 2, the physical channel type information of the configuration information indicates that the physical channel carrying the report includes one or more of the following: physical channel 0, or physical channel 1; the report type information of the configuration information indicates that the output method of the report includes any one of the following: periodic report sending, semi-static report sending, non-periodic report sending, or report sending a fixed number of times.

[0231] In another example, when the perception mode type information of the configuration information indicates perception mode 3, the physical channel type information of the configuration information indicates that the physical channel carrying the report includes one or more of the following: physical channel 2, or physical channel 3; the report type information of the configuration information indicates that the output method of the report includes any one of the following: periodic report sending, semi-static report sending, non-periodic report sending, or report sending repeatedly a fixed number of times.

[0232] In another example, when the perception mode type information of the configuration information indicates perception mode 4, the physical channel type information of the configuration information indicates that the physical channel carrying the report includes one or more of the following: physical channel 2, or physical channel 3; the report type information of the configuration information indicates that the output method of the report includes any one of the following: periodic report sending, semi-static report sending, non-periodic report sending, or report sending repeatedly a fixed number of times.

[0233] In another example, when the perception mode type information of the configuration information indicates perception mode 5, the physical channel type information of the configuration information indicates that the physical channel carrying the report includes one or more of the following: physical channel 2, physical channel 3, physical channel 4, physical channel 5, or physical channel 6; the report type information of the configuration information indicates that the output method of the report includes any one of the following: periodic report sending, semi-static report sending, non-periodic report sending, or report sending repeatedly a fixed number of times.

[0234] In one example, the constraint relationship between the resource type information in the measurement signal resource configuration information and the report type information in the report configuration information is shown in Table 9.

[0235] Table 9

[0236] In one example, if the resource type information indicates that the measurement signal is sent periodically, then the report type information can indicate that the report is sent in any of the following ways: periodic report sending, semi-static report sending, report sending a fixed number of times, or non-periodic report sending.

[0237] In another example, if the resource type information indicates that the measurement signal is sent in a semi-static manner, then the report type information can indicate that the report is sent in any of the following manner: semi-static report sending, fixed number of repeated report sending, or non-periodic report sending.

[0238] In another example, if the resource type information indicates that the measurement signal is sent repeatedly a fixed number of times, then the report type information can indicate that the report is sent in any of the following ways: the report is sent repeatedly a fixed number of times, or the report is sent non-periodically.

[0239] In another example, if the resource type information indicates that the measurement signal is sent in an aperiodic manner, then the report type information can indicate that the report is sent in an aperiodic manner.

[0240] In one example, the constraint relationship between the value of the resource type information and the transmission method of the measurement signal is shown in Table 10.

[0241] Table 10

[0242] In one example, the constraint relationship between report type information and the time-domain resource configuration information of the report is shown in Table 11.

[0243] Table 11

[0244] In Table 11, in one example, if the report type information indicates that the report is sent periodically, the time-domain resource configuration information of the report may include one or more of the following: the time-domain resource configuration information of the report, or the time-domain resource offset information of the report. In another example, if the report type information indicates that the report is sent semi-statically, the time-domain resource configuration information of the report may include one or more of the following: the time-domain resource configuration information of the report, the time-domain resource offset information of the report, or the power control information of the report. In yet another example, if the report type information indicates that the report is sent a non-periodicly, the time-domain resource configuration information of the report may include one or more of the following: the time-domain resource offset information of the report. In yet another example, if the report type information indicates that the report is sent repeatedly a fixed number of times, the time-domain resource configuration information of the report may include one or more of the following: the time-domain resource configuration information of the report, the time-domain resource offset information of the report, or the fixed-number repetition parameter.

[0245] It should be noted that in Table 9 or Table 11, " / " indicates that the configuration information does not include the information (or information element) corresponding to " / ", or " / " indicates that the corresponding information (or information element) in the configuration information is configured as empty.

[0246] 602. The second device sends configuration information to the third device, indicating the sensing mode and the resources for the corresponding report.

[0247] In step 602, after obtaining the configuration information from the second device, the third device determines the resources for sending the report based on the configuration information. For details regarding the configuration information, please refer to the description of step 601; it will not be repeated here.

[0248] 603. The first device sends a measurement signal to the third device.

[0249] Optionally, the first device acquires the configuration information of the measurement signal, and then sends the measurement signal to the third device based on the configuration information. For details regarding the configuration information of the measurement signal, please refer to step 601; it will not be elaborated upon here.

[0250] 604. The third device sends a report to the first device, which is carried on the resources of the report corresponding to the perception mode.

[0251] In step 604, the third device receives the measurement signal and obtains a measurement result based on the measurement signal. Then, the third device sends a report to the first device, which includes the measurement result of the measurement signal and carries the resources of the report corresponding to the sensing mode.

[0252] The following are several example scenarios:

[0253] In one example scenario, if both the first device and the third device are first network devices, and the value of the sensing mode type information in the configuration information is 0, the configuration information indicates that the sensing mode is sensing mode 0, meaning the direction of the measurement signal transmission is self-transmission and self-reception by the base station. Then, the first network device determines the report of the measurement signal based on the received measurement signal.

[0254] In another example scenario, if the first device is a first network device and the third device is a second network device, and the first and second network devices are different, the value of the perception mode type information in the configuration information is 1, indicating that the perception mode is perception mode 1, that is, the direction of the measurement signal transmission is from base station A to base station B. Accordingly, the second network device sends a report of the measurement signal to the first network device.

[0255] In another example scenario, if the first device is a first network device and the third device is a terminal device, and the value of the perception mode type information in the configuration information is 2, the configuration information indicates that the perception mode is perception mode 2, meaning that the direction of the measurement signal transmission is base station transmission and UE reception. Accordingly, the terminal device sends a report of the measurement signal to the first network device.

[0256] In another example scenario, if the first device is a terminal device and the third device is a network device, and the value of the perception mode type information in the configuration information is 3, the configuration information indicates that the perception mode is perception mode 3, meaning that the direction of the measurement signal transmission is UE-to-base-to-receive. Accordingly, the network device determines the report of the measurement signal based on the received measurement signal.

[0257] In another example scenario, if both the first device and the third device are first terminal devices, and the value of the perception mode type information in the configuration information is 4, the configuration information indicates that the perception mode is perception mode 4, meaning that the direction of the measurement signal transmission is UE self-transmission and self-reception. After the first terminal device determines the report of the measurement signal based on the received measurement signal, optionally, the first terminal device can send the report to the network device. The first terminal device can send the report to the network device according to the configuration information of the report.

[0258] In another example scenario, if the first device is a first terminal device and the third device is a second terminal device, and the value of the perception mode type information in the configuration information is 5, the configuration information indicates that the perception mode is perception mode 5, meaning the direction of the measurement signal transmission is UE A sending and UE B receiving. After the second terminal device determines the report of the received measurement signal, it can optionally send the report to the network device or the first terminal device. The second terminal device can send the report to the network device or the first terminal device according to the configuration information of the report.

[0259] In another example scenario, if the report type information in the configuration information is 0, and the third device determines that the report is sent periodically based on this report type information, then the third device determines that no additional activation command (or trigger signal) needs to be sent before sending the report.

[0260] In another example scenario, if the report type information in the configuration is set to 1 or 2, and the third device determines whether the report is sent in a semi-static or non-periodic manner based on this information, then the third device needs to send an activation command (or trigger signal) before sending the report. Only after the third device sends the activation command (or trigger signal) can the first device receive the report, so that the first device can receive the report in response to the activation command (or trigger signal).

[0261] In another example scenario, if the report type information in the configuration information is 3, and the third device determines that the report is sent repeatedly a fixed number of times based on this report type information, then the third device can send an activation command (or trigger signal) before sending the report, or the third device does not need to send an activation command (or trigger signal) before sending the report.

[0262] Optionally, the third device can also determine the time slot offset of the report as Y and the number of repeated transmissions of the report as K based on reportSlotConfig, reportSlotOffsetList, and reportRepetitionNumber, where Y is a positive integer greater than or equal to 1 and K is a positive integer greater than or equal to 1. Then, the third device sends a report of the measurement signal based on the time slot offset of the report as Y and the number of repeated transmissions of the report as K.

[0263] Through the above technical solutions, the integrated sensing and communication (ISAC) network can achieve unified control and flexible scheduling of multiple sensing modes. By configuring information, it enables sensing and measurement of signals under multiple sensing modes, and reports of measurement signals are reported back under various sensing modes. This leverages the advantages of different sensing modes and compensates for the shortcomings of a single sensing mode, ultimately allowing the ISAC network to increase sensing range, improve sensing accuracy, and optimize sensing overhead. Furthermore, the configuration information allows for flexible configuration of measurement signal reports suitable for different sensing modes, enabling unified scheduling of measurement signal reports across different sensing modes. This improves the accuracy of sensing measurements and reduces communication overhead.
