Description

A communication method and related apparatus

[0001] This application claims priority to Chinese Patent Application No. 202410517688.4, filed on April 26, 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 communication technology, and in particular to a communication method and related apparatus. Background Technology

[0003] Wireless communication can be a transmission communication between two or more communication nodes that does not propagate through conductors or cables. These communication nodes can generally include network devices and terminal devices.

[0004] Currently, in wireless communication systems, network devices can calculate and determine signal transmission resources, which may include time-domain resources, frequency-domain resources, etc., used to carry the signal. Correspondingly, terminal devices can transmit and receive signals on these transmission resources. In this way, network devices can provide wireless access communication services for network access to at least one terminal device.

[0005] With the development of communication technology, in addition to transmitting service data related to wireless access communication services, different communication nodes may also be involved in transmitting data from other services. However, how to transmit this service data is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] This application provides a communication method and related apparatus for transmitting sensing service data through a first wireless bearer to realize data transmission for sensing tasks.

[0007] The first aspect of this application provides a communication method, which is executed by a network device, or implemented by some components (e.g., processors, circuits, chips, or chip systems) of the network device, or implemented by a logic module or software that implements all or part of the functions of the network device. In this method, the network device determines first information for configuring a first radio bearer for transmitting data related to sensing services between a terminal device and the network device; the network device then transmits the first information.

[0008] Based on the above scheme, the first information sent by the network device is used to configure the first radio bearer, enabling the network device and the terminal device to transmit sensing service data based on the first radio bearer. In this way, in addition to transmitting data for wireless access communication services, the terminal device and the network device can also transmit sensing service data through the first radio bearer to achieve data transmission for sensing tasks.

[0009] Furthermore, the service data of wireless access communication services can be carried on a radio bearer between the terminal device and the network device. For example, if the service data is control signaling, it can be transmitted via a signaling radio bearer (SRB); if the service data is application data, it can be transmitted via a data radio bearer (DRB). In the above scheme, the first radio bearer can be different from the SRB and / or DRB. That is, the terminal device and the network device can realize the data transmission of the sensing task through a first radio bearer independent of the SRB and / or DRB, which can achieve isolation between the data transmission of the sensing task and the data transmission of the wireless access communication task, and avoid affecting the data transmission of the SRB and / or DRB.

[0010] As an example, the first radio bearer can be different from the SRB. Generally, the SRB is used to transmit air interface signaling with a small data volume, while the data of sensing tasks is generally characterized by a large data volume. Therefore, the implementation method of transmitting sensing service data through a first radio bearer that is different from the SRB can meet the service requirements of transmitting sensing data with a large data volume.

[0011] As another example, the first radio bearer can be different from the DRB. Generally, the DRB is used to transmit service data between terminal equipment and the data network (DN), while the data for sensing tasks is likely to be generated and terminated at terminal equipment and network equipment (e.g., access network equipment). Therefore, by using a first radio bearer that is different from the DRB to transmit the data for sensing services, the service requirements that the data generation node or termination node of the sensing data transmission is located in the network equipment can be met.

[0012] In this application, sensing technology can refer to the use of wireless signals to sense targets or states in the surrounding environment. For example, a terminal device or network device can use sensing technology to measure wireless signals and obtain measurement information such as the strength, delay, phase change, and Doppler shift of the wireless signals. After processing, the measurement information is output as measurement results, such as one or more of the following: geographical location, distance, speed, angle, map, attitude, scale, imaging, or material.

[0013] Furthermore, perception services can be services implemented based on perception technologies. For example, perception services may include one or more of the following: presence detection services, imaging services of the environment or target objects, target recognition services, environmental perception, target localization and tracking, or target imaging.

[0014] In this application, the data of the sensing service may include one or more of the following: signal-level measurement results (i.e., sensing results obtained based on the sensing signal), spectral information corresponding to the signal, point cloud information, and target-level sensing information (i.e., sensing results for the sensing target).

[0015] In one possible implementation of the first aspect, the method further includes: the network device receiving capability information from the terminal device, the capability information being used to determine the first information.

[0016] Optionally, this capability information is used to trigger, indicate, or request the first information.

[0017] Based on the above scheme, the network device can determine and send the first information for configuring the first radio bearer based on the capability information sent by the terminal device, so that the network device can configure the corresponding radio bearer based on the capabilities of the terminal device to realize the data transmission of sensing services.

[0018] Optionally, the capability information is used to indicate at least one of the following: the terminal device supports transmitting data of the sensing service, the terminal device supports establishing the first radio bearer, or the terminal device supports transmitting data of the sensing service in a first state; wherein the first state includes at least one of radio resource control (RRC) connected state, RRC inactive state, or RRC idle state.

[0019] In one possible implementation of the first aspect, the method further includes: the network device receiving request information from the terminal device, the request information being used to request the first information.

[0020] Optionally, the request information is used to trigger (or indicate, or determine) the first information.

[0021] Based on the above scheme, the network device can determine and send the first information for configuring the first radio bearer based on the request information sent by the terminal device, so that the network device can configure the corresponding radio bearer based on the request of the terminal device to realize the data transmission of the sensing service.

[0022] Optionally, the request information is used to indicate at least one of the following: the requested service type is a sensing service, the reason value for the request is, the amount of data requested to be transmitted for the sensing service is, or the data type of the data requested to be transmitted for the sensing service is.

[0023] For example, the reason value of the request can indicate that the reason for the request is to request the reporting of sensing data, or to request the establishment of a sensing dedicated bearer (i.e., the first radio bearer).

[0024] In one possible implementation of the first aspect, the method further includes: the network device receiving second information from an entity for sensing (e.g., a first entity), the second information being used to determine the first information.

[0025] Optionally, the second information is used to trigger (or indicate, or request) the first information.

[0026] Based on the above scheme, the network device can determine and send first information for configuring the first radio bearer based on the second information sent by the first entity. The first entity can be used for sensing, so that the network device can configure the corresponding radio bearer based on the indication of the sensing entity to realize the data transmission of sensing services.

[0027] Optionally, the second information is used to indicate at least one of the following: transmitting the data of the sensing service between the terminal device and the network device, establishing the first radio bearer, the quality of service (QoS) information of the data transmission of the sensing service, the data volume of the sensing service, or the data type of the sensing service.

[0028] In one possible implementation of the first aspect, the data of the sensing service is contained in a message of the first protocol layer; the method further includes: the network device sending third information for configuring the first protocol layer.

[0029] Based on the above scheme, the network device can also send third information for configuring the first protocol layer to the terminal device, so that the terminal device can realize the data transmission of sensing services based on the first protocol layer.

[0030] Optionally, the third information is used to indicate at least one of the following: whether the first protocol layer supports segmentation, the maximum segmentation size supported by the first protocol layer, or the mapping relationship between the QoS and transmission priority of the data transmission of the first protocol layer.

[0031] Optionally, since sensing services differ from radio access communication services, the first protocol layer used to transmit data for sensing services may differ from the second protocol layer used to transmit data for radio access communication services. For example, the second protocol layer may include a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer, etc.

[0032] In one possible implementation of the first aspect, the first information includes at least one of the following: index information of the first radio bearer, indication information indicating that the service corresponding to the first radio bearer is a sensing service, indication information indicating that the data of the sensing service is transmitted through the first radio bearer, indication information indicating the mapping relationship between the quality of service (QoS) and transmission priority of the sensing service, PCDP layer configuration information, RLC layer configuration information, MAC layer configuration information, PHY layer configuration information, or compression parameters of the data of the sensing service.

[0033] Based on the above scheme, the first information can be configured for the first wireless bearer through at least one of the above methods.

[0034] Optionally, the data of sensing services generally has the characteristic of large data volume. Therefore, when the first information includes the compression parameters of the sensing service data, the data of the sensing service can be compressed through the compression parameters of the sensing service data, so that the first wireless bearer can transmit the compressed data, which can meet the data transmission requirements of the sensing service, while also reducing the overhead through the data compression process.

[0035] Optionally, the MAC layer configuration information included in the first information may include the configuration of logical channels, which may include dedicated control channels (DCCH) or dedicated traffic channels (DTCH), etc. Wherein, when the first radio bearer is used to transmit data for sensing services and other data / signaling (e.g., data carried by DRB / SRB bearers), configuring logical channels can allocate a lower logical channel priority for data transmitting sensing services, thereby minimizing the impact on other data / signaling.

[0036] A second aspect of this application provides a communication method, which is executed by a terminal device, or implemented by some components (e.g., processor, circuit, chip, or chip system) in the terminal device, or implemented by a logic module or software that implements all or part of the functions of the terminal device. In this method, the terminal device receives first information for configuring a first radio bearer, the first radio bearer being used to transmit data of a sensing service between the terminal device and a network device; the terminal device transmits the sensing service data based on the first radio bearer.

[0037] Based on the above scheme, the first information received by the terminal device is used to configure the first wireless bearer, enabling the network device and the terminal device to transmit sensing service data based on the first wireless bearer. In this way, in addition to transmitting wireless access communication service data, the terminal device and the network device can also transmit sensing service data through the first wireless bearer to realize the data transmission of sensing tasks.

[0038] Furthermore, the service data of wireless access communication services can be carried on a wireless bearer between terminal devices and network devices. For example, if the service data is control signaling, it can be transmitted via an SRB; if the service data is application data, it can be transmitted via a DRB. In the above scheme, the first wireless bearer can be different from the SRB and / or DRB. That is, the terminal device and network device can achieve data transmission of sensing tasks through a first wireless bearer independent of the SRB and / or DRB, which can isolate the data transmission of sensing tasks from the data transmission of wireless access communication tasks and avoid affecting the data transmission of SRB and / or DRB.

[0039] As an example, the first radio bearer can be different from the SRB. Generally, the SRB is used to transmit air interface signaling with a small data volume, while the data of sensing tasks is generally characterized by a large data volume. Therefore, the implementation method of transmitting sensing service data through a first radio bearer that is different from the SRB can meet the service requirements of transmitting sensing data with a large data volume.

[0040] As another example, the first radio bearer can be different from the DRB. Generally, the DRB is used to transmit service data between terminal equipment and the data network (DN), while the data for sensing tasks is likely to be generated and terminated at terminal equipment and network equipment (e.g., access network equipment). Therefore, by using a first radio bearer that is different from the DRB to transmit the data for sensing services, the service requirements that the data generation node or termination node of the sensing data transmission is located in the network equipment can be met.

[0041] In one possible implementation of the second aspect, the method further includes: the terminal device sending capability information of the terminal device, the capability information being used to determine the first information.

[0042] Based on the above scheme, the network device can determine and send the first information for configuring the first radio bearer based on the capability information sent by the terminal device, so that the network device can configure the corresponding radio bearer based on the capabilities of the terminal device to realize the data transmission of sensing services.

[0043] Optionally, the capability information is used to indicate at least one of the following: the terminal device supports transmitting data of the sensing service, the terminal device supports establishing the first radio bearer, or the terminal device supports transmitting data of the sensing service in a first state; wherein the first state includes at least one of Radio Resource Control (RRC) connected state, RRC inactive state, or RRC idle state.

[0044] In one possible implementation of the second aspect, the method further includes: the terminal device sending request information for requesting the first information.

[0045] Based on the above scheme, the network device can determine and send the first information for configuring the first radio bearer based on the request information sent by the terminal device, so that the network device can configure the corresponding radio bearer based on the request of the terminal device to realize the data transmission of the sensing service.

[0046] Optionally, the request information is used to indicate at least one of the following: the requested service type is a sensing service, the reason value for the request is, the amount of data requested to be transmitted for the sensing service is, or the data type of the data requested to be transmitted for the sensing service is.

[0047] In one possible implementation of the second aspect, the data of the sensing service is contained in a message of the first protocol layer; the method further includes: the terminal device receiving third information, the third information being used to configure the first protocol layer.

[0048] Based on the above scheme, the network device can also send third information for configuring the first protocol layer to the terminal device, so that the terminal device can realize the data transmission of sensing services based on the first protocol layer.

[0049] Optionally, the third information is used to indicate at least one of the following: whether the first protocol layer supports segmentation, the maximum segmentation size supported by the first protocol layer, or the mapping relationship between the QoS and transmission priority of the data transmission of the first protocol layer.

[0050] In one possible implementation of the second aspect, the first information includes at least one of the following: index information of the first radio bearer, indication information indicating that the service corresponding to the first radio bearer is a sensing service, indication information indicating that the data of the sensing service is transmitted through the first radio bearer, indication information indicating the mapping relationship between the quality of service (QoS) and transmission priority of the sensing service, PCDP layer configuration information, RLC layer configuration information, MAC layer configuration information, PHY layer configuration information, or compression parameters of the data of the sensing service.

[0051] Based on the above scheme, the first information can be configured for the first wireless bearer through at least one of the above methods.

[0052] A third aspect of this application provides a communication method, which is executed by a first entity, or by some components of the first entity (e.g., a processor, circuit, chip, or chip system), or may be implemented by a logic module or software capable of implementing all or part of the functions of the first entity. In this third aspect and its possible implementations, the method is described as being executed by a first entity. In this method, the first entity determines second information, which is used to determine first information; wherein the first information is used to configure a first radio bearer, which is used to transmit data for sensing services between a terminal device and a network device; the first entity sends the second information to the network device.

[0053] Based on the above scheme, the second information sent by the first entity to the network device can be used to determine the first information, wherein the first information is used to configure the first radio bearer, which is used to transmit data of sensing services between the terminal device and the network device. In this way, in addition to transmitting data of wireless access communication services, the terminal device and the network device can also transmit data of sensing services through the first radio bearer to realize the data transmission of sensing tasks.

[0054] Furthermore, the service data of wireless access communication services can be carried on a wireless bearer between terminal devices and network devices. For example, if the service data is control signaling, it can be transmitted via an SRB; if the service data is application data, it can be transmitted via a DRB. In the above scheme, the first wireless bearer can be different from the SRB and / or DRB. That is, the terminal device and network device can achieve data transmission of sensing tasks through a first wireless bearer independent of the SRB and / or DRB, which can isolate the data transmission of sensing tasks from the data transmission of wireless access communication tasks and avoid affecting the data transmission of SRB and / or DRB.

[0055] As an example, the first radio bearer can be different from the SRB. Generally, the SRB is used to transmit air interface signaling with a small data volume, while the data of sensing tasks is generally characterized by a large data volume. Therefore, the implementation method of transmitting sensing service data through a first radio bearer that is different from the SRB can meet the service requirements of transmitting sensing data with a large data volume.

[0056] As another example, the first radio bearer can be different from the DRB. Generally, the DRB is used to transmit service data between terminal equipment and the data network (DN), while the data for sensing tasks is likely to be generated and terminated at terminal equipment and network equipment (e.g., access network equipment). Therefore, by using a first radio bearer that is different from the DRB to transmit the data for sensing services, the service requirements that the data generation node or termination node of the sensing data transmission is located in the network equipment can be met.

[0057] It should be understood that the first entity can be an entity used for sensing. This first entity can be an entity integrated into network devices (such as access network devices, core network devices, etc.) or a stand-alone device; there is no limitation here. As an example, when the first entity is used for sensing, it can be a sensing function (SF) entity / network element, a sensing control (SC) entity / network element, or other entities / network elements in the communication network that possess sensing functions.

[0058] Optionally, the second information is used to indicate at least one of the following: transmitting the data of the sensing service between the terminal device and the network device, establishing the first radio bearer, the quality of service (QoS) information of the data transmission of the sensing service, the data volume of the sensing service, or the data type of the sensing service.

[0078] First, some terms used in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0079] (1) Terminal device: can be a wireless terminal device that can receive network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0080] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN.

Currently, some examples of RAN equipment include: base station, evolved NodeB (eNodeB), gNB (gNodeB) in 5G communication systems, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc. In addition, in a network structure, network equipment can include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including CU nodes and DU nodes.

[0083] Optionally, RAN nodes can also be macro base stations, micro base stations, indoor stations, relay nodes, donor nodes, or radio controllers in cloud radio access network (CRAN) scenarios. RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, the access network equipment in V2X technology can be a roadside unit (RSU).

[0084] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be separate entities or included in the same network element, such as a baseband unit (BBU).

[0085] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or 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.

[0089] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or form of the network device. For ease of description, the embodiments of this application are not limited.

Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0091] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0092] (3) Configuration and Pre-configuration: In this application, both configuration and pre-configuration are used. Configuration refers to the network device sending configuration information or parameter values ​​of some parameters to the terminal device through messages or signaling, so that the terminal device can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​that the network device and the terminal device have negotiated in advance, or it can be parameter information or parameter values ​​that the network device or the terminal device uses as specified by the standard protocol, or it can be parameter information or parameter values ​​that are pre-stored in the network device or the terminal device. This application does not limit this.

[0093] Furthermore, these values ​​and parameters can be changed or updated.

[0094] (4) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more" means 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 mean: A exists alone, A and B exist simultaneously, or B exists 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.

[0095] (5) 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 through the air interface or sending indirectly through the air interface by 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 through the air interface or receiving indirectly from YY through the air interface by 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.

[0096] 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.

[0097] 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.

[0098] (6) In the embodiments of this application, "instruction" may 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 an association 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 of the information to be instructed are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement order 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 sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0099] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The embodiments described below do not constitute a limitation on the scope of protection of this application.

[0100] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0101] Please refer to Figure 1a, which is a schematic diagram of the architecture of the communication system 1000 used in the embodiments of this application. As shown in Figure 1a, the communication system includes a RAN 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (110a and 110b in Figure 1a, collectively referred to as 110), and may also include at least one terminal (120a-120j in Figure 1a, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1a). The terminal 120 is wirelessly connected to the RAN node 110, and the RAN node 110 is wirelessly or wiredly connected to the core network 200. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or they can be the same physical device integrating the logical functions of the core network equipment and the logical functions of the RAN node. Terminals can be connected to each other, as can RAN nodes, via wired or wireless means.

[0102] The core network equipment that may be involved in this application includes:

[0103] Access and mobility management function (AMF) devices / network elements / entities are deployed in the wireless core network to manage the access and mobility of terminal devices, performing registration, connection, reachability, and mobility management. AMF can also provide a session management message transmission channel for terminal devices and session management function (SMF) network elements, providing authentication and authorization functions for user access, and serving as an access point for the terminal and the wireless core network control plane.

[0104] User plane function (UPF) devices / network elements / entities refer to the user plane, which carries data traffic and is responsible for forwarding traffic between the radio access network and the Internet, reporting traffic usage, and enforcing quality of service (QoS) policies.

[0105] Figure 1b is a schematic diagram of the application framework involving the RIC module under the O-RAN architecture. As shown in Figure 1b, the communication system includes a RAN intelligent controller (RIC). The RIC includes near-real-time RIC (near-RT RIC) and non-real-time RIC (non-RT RIC).

[0106] As an example, the near real-time RIC in Figure 1b is used for model training and inference. For instance, it can be used to train an AI model, which is then used for inference. The near real-time RIC can obtain network-side and / or terminal-side information from RAN nodes (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or terminals. This information can be used as training data or inference data. Optionally, the near real-time RIC can deliver the inference results to the RAN nodes and / or terminals. Optionally, inference results can be exchanged between CU and DU, and / or between DU and RU. For example, the near real-time RIC delivers the inference results to the DU, and the DU sends them to the RU.

[0107] As another example, the non-real-time RIC in Figure 1b is used for model training and inference. For example, it can be used to train an AI model and then use that AI model for inference. The non-real-time RIC can obtain network-side and / or terminal-side information from RAN nodes (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or terminals. This information can be used as training data or inference data, and the inference results can be delivered to the RAN nodes and / or terminals. Optionally, inference results can be exchanged between CU and DU, and / or between DU and RU; for example, the non-real-time RIC delivers the inference results to the DU, which then forwards them to the RU.

[0108] As another example, the near real-time RIC and non-real-time RIC in Figure 1b can also be set up as separate network elements. Optionally, the near real-time RIC and non-real-time RIC can also be part of other devices. For example, the near real-time RIC can be set in the RAN node (e.g., in the CU or DU), while the non-real-time RIC can be set in the operation, administration and maintenance (OAM) system, cloud server, core network device, or other network device.

[0109] Figure 1c shows an example diagram of an O-RAN system, which may include other components besides those shown in the figure. As shown, the access network device (RAN, such as an eNB, gNB, or next-generation access network device) communicates with the core network (CN) via a backhaul link and with the UE via an air interface.

[0110] In one possible implementation, this application can be applied to LTE wireless communication systems, NR wireless communication systems, and future evolved NR wireless communication systems. For example, this application can be applied to orthogonal frequency division multiplexing (OFDM) systems in LTE, OFDM systems in NR, future OFDM systems, and OFDM-like systems.

[0111] In wireless communication systems (such as those shown in Figures 1a, 1b, or 1c), wireless communication sensing fusion is one of the key technologies in current communication network research, and it can be widely used in typical application scenarios such as intelligent transportation, intelligent low-altitude airspace, and intelligent networks. Communication sensing fusion achieves unified design of communication and sensing functions through signal joint design and hardware sharing. Sensing in communication sensing fusion can be understood as wireless sensing technology based on the communication system. For example, a base station transmits wireless signals to a target area or object and receives the echo signals reflected by the object. By analyzing the received signals, corresponding sensing measurements are obtained, such as the number, location, speed, and identification of the target object.

[0112] Generally, based on whether the perception requirement is area-oriented or target-oriented, perception can be divided into per-area and per-object synesthetic scenarios.

[0113] As an example, area-oriented perception targets a specific area, such as urban low-altitude areas, roads, factories, etc. Typical applications include: locating and tracking drones that intrude into the monitored area in urban low-altitude areas, thereby achieving drone intrusion detection for fixed areas; detecting the movement trajectory and speed of vehicles on urban roads in real time and uploading the sensing data to the positioning processing center to perceive the operating status of highways; performing breathing detection, fitness monitoring, gesture / posture recognition, etc., by sensing changes in the sensing channel; and analyzing the relationship between signal attenuation in the communication link and weather indicators to obtain corresponding weather indicators and perform weather detection, etc.

[0114] As another example, target-oriented detection uses sensing technology to perceive and track target objects when the target has an identifier (e.g., the target has a subscriber identification module (SIM) card that can establish an air interface connection with the network) in order to obtain the scenario of dynamic detection of the perceived object.

[0115] The sensing signal may be transmitted between access network devices and terminal devices, between terminal devices, and between access network devices. The process shown in Figure 2 will be described below as an example.

[0116] As shown in Figure 2, the sensing signal can have the following six modes:

[0117] (a) The access network device sends a sensing signal, and the access network device receives the sensing signal.

[0118] (b) The terminal device sends a sensing signal, and the terminal device receives the sensing signal.

[0119] (c) One access network device sends a sensing signal, and another access network device receives the sensing signal.

[0120] (d) One terminal device sends a sensing signal, and another terminal device receives the sensing signal.

[0121] (e) The access network device sends a sensing signal, and the terminal device receives the sensing signal.

[0122] (f) The terminal device sends a sensing signal, and the access network device receives the sensing signal.

[0123] Furthermore, to enable the communication network to possess sensing function (SF), it may be necessary to deploy network elements with sensing capabilities in the network equipment. The following will introduce some possible deployment methods for network elements with sensing capabilities.

[0124] As shown in Figure 3a, devices / network elements / entities with sensing capabilities can be deployed in the core network, i.e., the SF shown in Figure 3a. The SF can be a network element in the core network that provides sensing-related functions, including: management of sensing nodes, coordination of sensing resources, processing of sensing measurements, and sharing of sensing results, etc., i.e., possible sensing-related functions.

[0125] In Figure 3a, access network devices can communicate with UPF network elements through the NG-U interface; access network devices can communicate with AMF network elements through the NG-C interface; access network devices can communicate with each other through the Xn interface; and terminal devices can communicate with access network devices through the Uu interface.

[0126] Optionally, SF is a network element deployed on the network side that can provide sensing-related services. The name is merely an example and can be other names, such as sensing function network element, sensing requirement network element, sensing management network element, etc. Access network devices can connect to SF through AMF or UPF. In a special case, SF and LMF are co-located, or the LMF is extended to implement the functions of SF.

[0127] For example, as shown in Figure 3a, the SF can be divided into SF control plane (SF-C) network elements and SF user plane (SF-U) network elements. In this case, the access network equipment communicates with the SF-U network elements through the UPF network element and with the SF-C network elements through the AMF network element.

[0128] For example, access network devices can also connect directly to the SF, meaning they do not need to communicate with the SF through the UPF and AMF. In this case, the SF can also be divided into SF-C and SF-U.

[0129] It should be understood that the sensing functions deployed in the core network can have other names besides SF, such as sensing function network element, sensing requirement network element, sensing management network element, etc., and there is no limitation here.

[0130] As shown in Figures 3b and 3c, devices / network elements / entities with sensing capabilities can be deployed in the core network, specifically the sensing control (SC) devices / network elements / entities shown in Figure 3b. In Figure 3b, the SC can be a device / network element / entity independently set up in the access network equipment; in Figure 3c, the SC can be a device / network element / entity integrated into the access network equipment. In Figures 3b and 3c, the SF is optional. That is, the SC can exist independently, or the SC and SF can be deployed simultaneously. When deployed simultaneously, the functions between the SC and SF network elements are not limited.

[0131] Here, SC represents a sensing-related network element set up on the RAN side. This network element can be a base station, a network element deployed on a base station, or a network element deployed independently of the base station. This network element may have at least one of the following capabilities:

[0132] It receives sensing requests from SF, manages sensing nodes, coordinates sensing resources within the region, processes sensing measurement results, and directly receives sensing requests (possessing all the functions of SF).

[0133] Optionally, the sensing function deployed in the access network can have other names besides SC, such as sensing control network element, control network element, sensing control node, edge sensing function, edge control network element, edge control node, etc., without limitation here.

[0134] As shown in Figures 3d and 3e, these are examples of scenarios where both the core network and the access network are equipped with sensing devices / network elements / entities.

[0135] For example, in Figure 3d, the devices / network elements / entities with sensing capabilities deployed in the access network may include SC network element #1 and SC network element #2, which are independent of the access network devices. Optionally, the relationship between the access network element and the SC network element can be one-to-one as shown in Figure 3d, or it can be one-to-many, or many-to-one; no limitation is made here.

[0136] For example, in Figure 3e, the devices / network elements / entities with sensing capabilities deployed in the access network may include SC network element #1 and SC network element #2 integrated into the access network devices.

[0137] For example, in Figures 3d and 3e, the sensing-enabled devices / network elements / entities deployed in the core network may include SF network elements.

[0138] In a wireless communication system (such as the systems shown in Figures 1a, 1b, or 1c), the network device can calculate and determine the transmission resources for signals. These transmission resources may include time-domain resources, frequency-domain resources, etc., used to carry the signals. Correspondingly, the terminal device can transmit and receive signals on these transmission resources. In this way, the network device can provide wireless access communication services for network access to at least one terminal device. The service data of the wireless access communication service can be transmitted via a signaling radio bearer (SRB) or a data radio bearer (DRB), which will be described below.

[0139] SRB is used to transmit control plane signaling. SRB includes several possible implementations, as described below.

[0140] SRB0: Transmits RRC messages, such as RRC connection establishment requests and RRC connection re-establishment requests. Optionally, SRB0 does not need to be configured.

[0141] SRB1: Transmits RRC messages and NAS messages, such as RRC reconfiguration and RRC release. Optionally, SRB1 is configured via Msg3.

[0142] SRB2: Transmits non-access stratum (NAS) messages and RRC messages carrying recorded measurement information. It has lower priority than SRB1 and is typically configured after access stratum (AS) security activation. Optionally, SRB2 is configured via Radio Resource Control Reconfiguration (RRC Reconfiguration) messages.

[0143] SRB3: Transmits special RRC messages in scenarios of Universal Mobile Telecommunications System (UMTS) terrestrial radio access network and EUTRA-NR dual connective (ENDC) or NR dual connective (ENDC).

[0144] SRB4: Used for transmitting application layer measurement report information, with a lower priority than SRB1.

[0145] SRB5: Used for transmitting application layer measurement report information in EN-DC or NR-DC scenarios, with a lower priority than SRB1 and SRB3.

[0146] Optionally, under shared spectrum channel access, SRB0, SRB1, and SRB3 are assigned the highest priority, while the priorities of SRB2 / 4 / 5 are configurable.

[0147] DRBs are used to transmit user data. For example, DRBs can be configured via RRC Reconfiguration, and there can be a one-to-many relationship between DRBs and Quality of Service (QoS) flows.

[0148] Furthermore, with the development of communication technology, in addition to transmitting service data related to wireless access communication services, different communication nodes may also be involved in the transmission of data for other services. As described above, future communication networks may possess sensing capabilities. However, the wireless bearers currently used for data transmission in wireless access communication services may not be suitable for transmitting data for sensing services.

[0149] For example, during the transmission process corresponding to SRBs, such as SRB0, SRB1, SRB2, and SRB3, the control plane signaling transmitted is generally in small-sized messages, while the data volume of sensing services (such as point cloud, map, etc.) is large, which may cause these SRBs to be unable to realize the data transmission of sensing services.

[0150] For example, in the transmission process corresponding to DRB, the user plane data carried by DRB comes from or terminates in the data network, while the data of sensing services is likely to come from or terminate in network devices. This makes DRB unsuitable for the data transmission of sensing services.

[0151] Therefore, how to transmit sensing service data between network devices and terminal devices is a technical problem that urgently needs to be solved.

[0152] Please refer to Figure 4, which is a schematic diagram of the communication method provided in this application. The method includes the following steps.

[0153] It should be understood that Figure 4 illustrates the method by using different communication devices (e.g., the first entity, network device, terminal device, etc.) as the executing entities of the interaction steps, but this application does not limit the executing entity of the interaction steps. For example, in the implementation process of Figure 4, the interaction steps can be executed by the communication device, or by a chip, chip system, processor, logic module, or software that supports the communication device to implement the interaction steps.

[0154] Optionally, in Figure 4 below, the network device can be an access network device, which can be an ORAN network element. For example, the network device may include an O-CU, an O-DU, and an O-RU. In step S401 below, the first information can be determined by the O-CU and / or the O-DU, and the first information can be sent to the terminal device through the O-RU. In step S402 below, the data of the sensing service based on the first radio bearer transmission can be determined by the O-CU and / or the O-DU.

[0155] S401. The network device sends first information, and correspondingly, the terminal device receives the first information. The first information is used to configure a first radio bearer, which is used to transmit data for sensing services between the terminal device and the network device.

[0156] Optionally, the data for sensing business can be replaced with other data, such as sensing data, sensing-related data, etc.

[0157] In one possible implementation, the first information includes at least one of the following information 1 to information 9:

[0158] Information 1. Indicates the index information of the first radio bearer.

[0159] Information 2 indicates that the service corresponding to the first radio bearer is a sensing service.

[0160] Information 3. Indicates that the data for the sensing service is transmitted through the first wireless bearer.

[0161] Information 4 includes PDCP layer configuration information.

[0162] Information 5 includes RLC layer configuration information.

[0163] Information 6 includes MAC layer configuration information.

[0164] Information 7 includes PHY layer configuration information.

[0165] Information 8. Includes compression parameters for data related to sensing services.

[0166] Information 9. Indications include information indicating the mapping relationship between QoS and transmission priority of perceived services.

[0167] Therefore, the first information can be used to configure the first wireless bearer through at least one of the above methods.

[0168] For example, when there are one or more wireless bearers between a network device and a terminal device, the network device can distinguish between different wireless bearers through information 1, and subsequently process the first wireless bearer (e.g., update, release, etc.) through the index of the first wireless operation.

[0169] For example, the wireless bearer between the network device and the terminal device may be used to transmit data for one or more services. Accordingly, the network device can indicate through information 2 or information 3 that the first wireless bearer is used to transmit data for sensing services. Subsequently, the network device and the terminal device can realize the data transmission of sensing services based on the first wireless bearer in step S402.

[0170] For example, service data between network devices and terminal devices may need to be processed through one or more protocol layers (such as PDCP layer, MAC layer, physical layer or more). Accordingly, the terminal device can configure these protocol layers through at least one of information 4, information 5, information 6, and information 7, so as to realize the data processing of the perceived service based on the configuration of these protocol layers.

[0171] Optionally, the first information, including information 6 (i.e., MAC layer configuration information), may include the configuration of logical channels. These logical channels may include dedicated control channels (DCCH) or dedicated traffic channels (DTCH), etc. Specifically, when the first radio bearer is used to transmit data for sensing services and other data / signaling (e.g., data carried by DRB / SRB bearers), configuring logical channels can allocate a lower logical channel priority for the data transmitting sensing services, thereby minimizing the impact on other data / signaling.

[0172] For example, network devices can configure compression parameters through information 8. Subsequently, network devices and terminal devices can transmit data for sensing services based on these compression parameters, which can reduce the overhead of air interface transmission and reduce air interface transmission latency, thereby improving data transmission efficiency.

[0173] Optionally, the data of sensing services generally has the characteristic of large data volume. Therefore, when the first information includes information 8 (i.e. the compression parameters of the sensing service data), the data of sensing services can be compressed through the compression parameters of the sensing service data, so that the first wireless bearer can transmit the compressed data, which can meet the data transmission requirements of sensing services, while also reducing overhead through the data compression process.

[0174] For example, network devices can use information 9 to determine the priority of different sensing services. This facilitates differentiated processing of sensing services with different QoS requirements when transmitting data for sensing services.

[0175] Furthermore, the first wireless bearer of the first information configuration can be implemented in the following ways.

[0176] Case 1. The first radio bearer is SRB4 or SRB5.

[0177] In scenario 1, the first radio bearer can be configured via an RRC message, meaning the first information can be an RRC message. For example, taking an RRC Reconfiguration message as an example, in the RRC Reconfiguration message, the data indicating that the service type (serviveType) in the MeasConfigAppLayer-r17 field is a sensing service (i.e., the information carried by the MeasConfigAppLayer-r17 field can be the aforementioned information 2 or information 3), such as integrated sensing and communication (ISAC), sensing, etc., is transmitted via SRB4 or SRB5.

[0178] Case 2. The first radio bearer is a new SRB (e.g., SRBx, where x is a positive integer or x is an integer greater than 5).

[0179] In scenario 2, the first information may include one or more of the following:

[0180] The indication sensing data is reported via SRBx, as can be found in information 2 or information 3 above;

[0181] The configuration information for SRBx, including the configuration information for protocol layers such as PDCP, RLC, MAC, and PHY, can be found in Information 4 to Information 7 above. Optionally, the configuration information for the MAC layer may include the configuration of logical channels, which may include dedicated control channels (DCCH) or dedicated traffic channels (DTCH), etc. As described in Information 6 above, in cases 1 and 2, the first radio bearer can be used to transmit data for sensing services as well as other data / signaling (e.g., data from DRB / SRB bearers). Therefore, by configuring logical channels, a lower logical channel priority can be configured for transmitting data for sensing services, thereby minimizing the impact on other data / signaling.

[0182] Optionally, SRB4 and SRB5 were introduced for quality of experience (QoE) measurement (e.g., QoE data volume is in the range of 1000–8000 bytes). However, the data transmission requirements for sensing data may be much higher than this. Taking point cloud data as an example, the data transmission requirement for each sensing cycle may reach hundreds of gigabits per second (Gbps). As shown in Case 1, if sensing service data is transmitted via SRB4 or SRB5, it may affect the transmission of QoE reports. Therefore, introducing a new SRB (i.e., SRBx) can effectively avoid the impact on the current data transmission of SRBs.

[0183] Case 3. The first radio bearer is different from the currently defined SRB and DRB.

[0184] In case 3, the first information used to configure the first radio bearer can be an RRC message, for example, the RRC message can be an RRC Reconfiguration message.

[0185] Optionally, in case 3, the RRC Reconfiguration message may include MAC layer configuration information (refer to the implementation of information 6 above), which may include the configuration of logical channels, such as DCCH or DTCH.

[0186] Optionally, the signaling bearer may have the capability to compress sensing data. For example, for point cloud data, it may indicate one or more of the following compression parameters or information: whether compression of sensing data is supported, and information about the sensing compression algorithm (see the implementation of information 8 above). This can reduce the overhead of air interface transmission and lower the air interface transmission latency.

[0187] Optionally, the first radio bearer configured in the RRC Reconfiguration message may also include information 9 as shown above (i.e., the mapping between QoS and transmission priority of the sensed service). This enables differentiated transmission for different types of sensed services.

[0188] In case 3, the name of the first radio bearer is not limited; for example, it can be called xRB, DRB, SRB, local data radio bearer (local DRB), etc.

[0189] Furthermore, in scenario 3, the first radio bearer can be different from the SRB. Generally, SRBs are used to transmit air interface signaling with relatively small data volumes, while sensing task data typically has a large data volume. Therefore, using a first radio bearer different from the SRB to transmit sensing service data can meet the service requirements of transmitting larger amounts of sensing data, without affecting the transmission of existing SRBs.

[0190] And / or, in case 3, the first radio bearer may be different from the DRB. Generally, the DRB is used to transmit service data between the terminal device and the data network, while the data of the sensing task is likely to be generated and terminated at the terminal device and network device (e.g., access network device). Therefore, the implementation method of transmitting sensing service data through a first radio bearer different from the DRB can meet the service requirements of the sensing data transmission data generation node or termination node being located in the network device.

[0191] Optionally, the first information is also used to configure the first protocol layer. In other words, the network device can also send configuration information of the first protocol layer to the terminal device, enabling the terminal device to transmit data for sensing services based on the first protocol layer.

[0192] Optionally, the compression information of the aforementioned sensed data (e.g., information 8), the mapping between the sensed service QoS and transmission priority (e.g., information 9), can also be functions of the first protocol layer. The configuration information of the first protocol layer may also include at least one of the following: whether the first protocol layer supports segmentation, or the maximum segmentation size supported by the first protocol layer.

[0193] The first protocol layer can be RRC or SDAP, or it can be a new protocol layer different from RRC and SDAP.

[0194] S402. Network devices and terminal devices transmit sensing service data based on a first radio bearer. For example, network devices send sensing service data to terminal devices through the first radio bearer, and / or, terminal devices send sensing service data to network devices through the first radio bearer.

[0195] In this application, sensing technology refers to the use of wireless signals to sense targets or states in the surrounding environment. For example, a terminal device or network device can use sensing technology to measure wireless signals and obtain measurement information such as the strength, delay, phase change, and Doppler shift of the wireless signals. After processing, the measurement information is output as measurement results, such as one or more of the following: geographical location, distance, speed, angle, map, attitude, scale, imaging, or material.

[0196] Furthermore, perception services can be services implemented based on perception technologies. For example, perception services may include one or more of the following: presence detection services, imaging services of the environment or target objects, target recognition services, environmental perception, target localization and tracking, or target imaging.

[0197] In this application, the data for sensing services can be implemented in one or more of the following ways, depending on the type of service:

[0198] 1. Signal-level measurement results, such as the raw received signal obtained by measuring the sensing reference signal.

[0199] 2. FFT processing of the received signal can obtain spectral information, namely the RV spectrum, or RD map. R represents range information, V represents velocity information, and D represents Doppler information. That is, the spectral information obtained by sensing includes the range, velocity, and Doppler information corresponding to the target object.

[0200] 3. Point cloud information: Further processing of the received signal can yield point cloud information. Point cloud information can also be understood as a set of points in space. Perceptual point cloud information contains perception-related information. For any point cloud data in the first point cloud, the feature information of the point cloud includes position information, Doppler information, velocity information, distance information, angle information, etc.

[0201] 4. Target-level perceptual information, such as information about the perceived object, including the object's characteristics, such as speed, position, type, material, trajectory, etc.

[0202] Based on the scheme shown in Figure 4, the first information sent by the network device in step S401 is used to configure the first radio bearer, enabling the network device and the terminal device to transmit sensing service data based on the first radio bearer in step S402. In this way, in addition to transmitting data for wireless access communication services, the terminal device and the network device can also transmit sensing service data through the first radio bearer to realize the data transmission of sensing tasks.

[0203] Furthermore, the service data of wireless access communication services can be carried on a wireless bearer between terminal devices and network devices. For example, if the service data is control signaling, it can be transmitted via an SRB; if the service data is application data, it can be transmitted via a DRB. In the above scheme, the first wireless bearer can be different from the SRB and / or DRB. That is, the terminal device and network device can achieve data transmission of sensing tasks through a first wireless bearer independent of the SRB and / or DRB, which can isolate the data transmission of sensing tasks from the data transmission of wireless access communication tasks and avoid affecting the data transmission of SRB and / or DRB.

[0204] Optionally, in addition to transmitting data for wireless communication access services and sensing services, the network device and the terminal device may also be used to transmit data for other services. For example, these other services may include: AI services, large-scale model services, computing services, etc. Accordingly, in the method shown in Figure 4, the first wireless bearer can be used to transmit data for these other services, that is, the aforementioned sensing services can be replaced with AI services, large-scale model services, computing services, etc.

[0205] In the method shown in Figure 4, the network device may trigger the transmission of the first information in step S401 in a variety of ways. For example, the network device may send the first information to the terminal device based on a pre-configured period, or the network device may trigger the transmission of the first information to the terminal device based on an instruction from another device. The latter will be used as an example for illustration below.

[0206] Example 1: The network device sends the first information based on the capabilities of the terminal device.

[0207] In Example 1, the method shown in Figure 4 further includes: the network device receiving capability information from the terminal device, which is used to determine the first information. In other words, the network device can determine and send the first information for configuring the first radio bearer based on the capability information sent by the terminal device, enabling the network device to configure the corresponding radio bearer based on the capabilities of the terminal device to realize the data transmission of the sensing service.

[0208] Optionally, this capability information is used to trigger, indicate, or request the first information.

[0209] Optionally, the capability information is used to indicate at least one of the following: the terminal device supports transmitting data of the sensing service, the terminal device supports establishing the first radio bearer, or the terminal device supports transmitting data of the sensing service in a first state; wherein the first state includes at least one of radio resource control (RRC) connected state, RRC inactive state, or RRC idle state.

[0210] Example 2: The network device sends the first information based on the request from the terminal device.

[0211] In Example 2, the method shown in Figure 4 further includes: the network device receiving request information from the terminal device, the request information being used to request the first information. In other words, the network device can determine and send the first information for configuring the first radio bearer based on the request information sent by the terminal device, enabling the network device to configure the corresponding radio bearer based on the request from the terminal device, thereby realizing the data transmission of the sensing service.

[0212] Optionally, the request information is used to trigger (or indicate, or determine) the first information.

[0213] Optionally, the request information is used to indicate at least one of the following: the requested service type is a sensing service, the reason value for the request is, the amount of data requested to be transmitted for the sensing service is, or the data type of the data requested to be transmitted for the sensing service is.

[0214] For example, the reason value of the request can indicate that the reason for the request is to request the reporting of sensing data, or to request the establishment of a sensing dedicated bearer (i.e., the first radio bearer).

[0215] In Example 3, the network device sends the first information based on the request / instruction / configuration of the first entity.

[0216] Optionally, in the following implementation process, the first entity can be an entity integrated into a network device (e.g., access network device, core network device, etc.) or a separately configured device. When the first entity is an access network device, it can be an ORAN network element, such as an O-CU, O-DU, or O-RU. In step S401 below, second information can be generated through the O-CU and / or O-DU, and then sent through the O-RU. Alternatively, the first entity can be deployed in the O-CU, O-DU, or O-RU.

[0217] In implementing Example 3, as shown in Figure 4, the method also includes:

[0218] In step S400, the first entity sends second information, and the network device receives the second information accordingly. The second information is used to determine the first information.

[0219] In other words, the network device can determine and send first information for configuring the first radio bearer based on the second information sent by the first entity, wherein the first entity can be used for sensing, so that the network device can configure the corresponding radio bearer based on the indication of the sensing entity to realize the data transmission of sensing services.

[0220] Optionally, the second information is used to trigger (or indicate, or request) the first information.

[0221] Optionally, the second information is used to indicate at least one of the following: transmitting the data of the sensing service between the terminal device and the network device, establishing the first radio bearer, the quality of service (QoS) information of the data transmission of the sensing service, the data volume of the sensing service, or the data type of the sensing service.

[0222] It should be understood that the first entity can be an entity used for sensing. This first entity can be an entity integrated into network devices (such as access network devices, core network devices, etc.) or a stand-alone device; there is no limitation here. As an example, when the first entity is used for sensing, it can be a sensing function (SF) entity / network element, a sensing control (SC) entity / network element, or other entities / network elements in the communication network that possess sensing functions.

[0223] For example, in the above process, the network device may not have sensing capabilities, and the first entity may be either SF or SC. Alternatively, the network device may have sensing capabilities (e.g., SC is integrated into the network device), and the first entity may be SF.
