[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202410895908.7, filed on July 4, 2024, and entitled “A communication method and apparatus”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a communication method and apparatus. BACKGROUND

[0004] Integrated sensing and communication (ISAC) is one of the important application scenarios in mobile communication systems. ISAC has multi-capabilities such as high-precision positioning, environment reconstruction, imaging and identification, which can greatly promote the application demand of ultra-high resolution and precision. In addition, ISAC also helps to improve the performance and efficiency of communication.

[0005] Currently, in the ISAC system, the sensing function (SF) of the core network device is mainly used to manage sensing tasks and process sensing data. For example, the SF can provide configuration for sensing to the access network device according to the sensing requirement from the application function (AF). After obtaining the sensing data from the access network device, the SF can process the sensing data and send the processed sensing result to the AF.

[0006] How to improve the efficiency of sensing management needs further research. SUMMARY

[0007] The present application provides a communication method and apparatus to improve the efficiency of sensing management.

[0008] In a first aspect, an embodiment of the present application provides a communication method, which can be applied to a first device at an access network side. The first device can be a first logical unit in an access network or a device (e.g., a module, a communication module, a circuit, a chip (such as a modem chip, a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core), a chip system, or a processor) in the first logical unit; or the first device can be a first access network device or a device (e.g., a module, a communication module, a circuit, a chip (such as a modem chip, a SoC chip or a SIP chip containing a modem core), a chip system, or a processor) in the first access network device. The first logical unit can be used for sensing. Optionally, the first access network device can include the first logical unit.

[0009] The method includes: receiving, by the first device, first information, the first information being used to indicate a first sensing requirement; and sending, by the first device, second information, the second information being used to determine a first sensing resource. The first sensing resource is used for receiving and / or sending of a sensing signal at the access network side, the receiving and / or sending of the sensing signal corresponding to a second sensing requirement, the second sensing requirement being determined according to the first sensing requirement.

[0010] In the method, after receiving the first information indicating the first sensing requirement, the first device at the access network side can send the second information used to determine the first sensing resource. In this way, the first sensing resource can be determined at the access network side. Since the device at the access network side can conveniently obtain the condition of the resource at the access network side, a sensing resource that is suitable for the condition at the access network side can be determined, and thus the sensing requirement can be met, the sensing performance can be improved, and the efficiency of sensing management can be improved.

[0011] In addition, since the device at the access network side can quickly obtain the condition of the resource at the access network side, the time delay for determining the sensing resource can be reduced, and thus the sensing performance can be improved, and the efficiency of sensing management can be improved.

[0012] In addition, in the method, the first device can be used for sensing, and the first device can be independent of a second device and / or a third device used for communication, and thus the expansibility of the first device can be improved, and thus the first device can be upgraded to meet a higher sensing requirement and better support evolution of future sensing functions.

The technical solutions in the embodiments of the present application can be applied to various communication systems, for example, a fourth generation (4th generation, 4G) mobile communication system (such as a long term evolution (long term evolution, LTE) system), a fifth generation (the 5th generation, 5G) mobile communication system (such as a new radio (new radio, NR) system), or a future communication system. The method provided by the embodiments of the present application can be applied to a terrestrial network communication system, or applied to a non-terrestrial network (non-terrestrial network, NTN) communication system. The NTN communication system may, for example, be a satellite communication system, or may include unmanned aerial vehicles, high altitude platform stations (high altitude platform station, HAPS), and other aerial access network devices, which are not limited by the present application.

[0099] The present application will present various aspects, embodiments or features around systems that can include a plurality of devices, components, modules, etc. It should be understood and appreciated that various systems can include additional devices, components, modules etc., and / or can not include all of the devices, components, modules etc. discussed in connection with the figures. Additionally, a combination of these approaches can be used.

[0100] To facilitate understanding of embodiments of the present application, FIG. 1A shows a possible, non-limiting system diagram. As shown in FIG. 1A, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 10 can also include the Internet 300.

[0101] The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1A, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1A, collectively referred to as 120). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1A), etc., can also be included in the RAN 100. The terminals 120 are connected to the RAN nodes 110 in a wireless manner. The RAN nodes 110 are connected to the core network 200 in a wireless or wired manner. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0102] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, such as a 4G, 5G mobile communication system, or a future communication system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (Wi-Fi or WiFi) system. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0103] The RAN node 110, which can also be referred to as a RAN entity or an access node, etc., forms part of the communication system 10 and can be configured to facilitate wireless access by the terminals. The RAN nodes 110 in the communication system 10 can be of the same type or of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, e.g., the network element 120i in Figure 1A can be a helicopter or a drone, which can be configured to move as a mobile base station, to the terminal 120j accessing the RAN 100 via the network element 120i, the network element 120i is a base station; but to the base station 110a, the network element 120i is a terminal. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication devices, e.g., the network elements 110a and 110b in Figure 1A can be understood as communication devices with base station functionalities, and the network elements 120a-120j can be understood as communication devices with terminal functionalities.

[0104] The RAN node can also be referred to as an access network device. In the following, the access network device is used unless specified otherwise.

[0105] In a possible scenario, the access network device can be a base station, an evolved NodeB (eNodeB), a transmission point (TP), an access point (AP), a transmission reception point (TRP), a mobile switching center, a next generation NodeB (gNB), a next generation NodeB in a future communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The access network device can be a macro base station (e.g., 110a in Figure 1A), a micro base station or an indoor station (e.g., 110b in Figure 1A), a relay node or a donor node, or a wireless controller in a CRAN scenario, a satellite, a drone, a balloon, or an airplane, etc. Optionally, the access network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle-to-everything (V2X) technology can be a road side unit (RSU). The access network device in the present application can also be implemented by software functions running on hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). The access network device in the present application can also be a logical node, a logical module or software that can implement all or part of the functions of the access network device.

[0106] In another possible scenario, a terminal implements wireless access with assistance of multiple access network devices, and different access network devices implement part of functions of a base station. For example, an access network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately configured, or can be included in a same network element, for example, a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). For example, as shown in FIG. 1B, a terminal implements wireless access with assistance of multiple access network devices, and the multiple access network devices can include a CU, a DU, and an RU. The CU can include a CU-CP and a CU-UP.

[0107] In different systems, the CU (or the CU-CP and the CU-UP), the DU, or the RU can also have different names, but a person skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an open CU (O-CU), the DU can also be referred to as an open DU (O-DU), the CU-CP can also be referred to as an open CU-CP (O-CU-CP), the CU-UP can also be referred to as an open CU-UP (O-CU-UP), and the RU can also be referred to as an open RU (O-RU). Any of the CU (or the CU-CP, the CU-UP), the DU, and the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0108] Optionally, when a terminal implements wireless access with assistance of multiple access network devices, different access network devices implement functions of part of protocol layers in a base station.

[0109] In some examples, as shown in (a) of FIG. 1C, the CU can implement the functions of a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer, and the DU can implement the functions of a radio link control (RLC) layer, a media access control (MAC) layer, and a physical (PHY) layer. The CU and the DU communicate through an F1 interface.

[0110] In other examples, as shown in (b) of FIG. 1C, the CU-CP can implement the functions of an RRC layer, a PDCP-control plane (PDCP-C), the CU-UP can implement the functions of an SDAP layer and a PDCP-user plane (PDCP-U), and the DU can implement the functions of an RLC layer, a MAC layer, and a PHY layer. The CU-CP and the DU communicate through an F1-C interface, the CU-UP and the DU communicate through an F1-U interface, and the CU-CP and the CU-UP communicate through an E1 interface.

[0111] In yet other examples, for the correspondence between network elements in an ORAN system and the protocol layer functions that they can implement, refer to Table 1 below.

[0112] Table 1

[0113] In the table, the PHY-high function can include at least one of forward error correction (FEC) encoding / decoding, scrambling / descrambling, or modulation / demodulation, and the PHY-low function can include at least one of fast Fourier transform (FFT) transform / inverse fast Fourier transform (iFFT) transform, digital beamforming, or extraction and filtering of a physical random access channel (PRACH).

[0114] A terminal can also be referred to as terminal device, user equipment (UE), mobile station, mobile terminal, wireless terminal device, subscriber unit, subscriber station, mobile station (mobile station), remote station, user terminal device, user agent, or user device, etc. The terminal can be widely applied to various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart traffic, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, unmanned aerial vehicle, helicopter, airplane, ship, robot, mechanical arm, smart home device, etc. Among them, the wearable device can also be referred to as wearable smart device or smart wearable device, etc., which is a general term of devices that can be worn by applying wearable technology to the intelligent design and development of daily wear. The terminal applied to the vehicle can be referred to as vehicle-mounted terminal device, which is also referred to as on-board unit (OBU), for example.

[0115] For example, the terminal can include a mobile phone (also referred to as a "cellular" phone), a computer with mobile terminal device, or a portable, pocket, handheld, computer-embedded mobile device, etc. For example, the terminal can be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. The terminal can also include a limited device, such as a device with limited power consumption, or a device with limited storage capacity, or a device with limited computing capacity, etc. For example, the terminal can be a bar code, radio frequency identification (RFID), sensor, global positioning system (GPS), or laser scanner, etc. The embodiments of the present application do not limit the device form of the terminal.

[0116] In this application, the core network device refers to a device in the core network that provides service support for the terminal. Currently, some examples of core network devices are: access and mobility management function (AMF) entity, session management function (SMF) entity, user plane function (UPF) entity, etc., which are not listed one by one here. Among them, the AMF entity can be responsible for access management and mobility management of the terminal; the SMF entity can be responsible for session management, such as session establishment of users, etc.; the UPF entity can be a functional entity of the user plane, mainly responsible for connecting external networks. It should be noted that the entity in this application can also be referred to as a network element or a functional entity, for example, the AMF entity can also be referred to as an AMF network element or an AMF functional entity, and for example, the SMF entity can also be referred to as an SMF network element or an SMF functional entity, etc.

[0117] The present application can be applicable to scenario 1 and / or scenario 2.

[0118] Scenario 1: The communication system in scenario 1 can include a perception management network element, a first device on the access network side, and a second device on the access network side. Optionally, the communication system further includes a third device on the access network side. Among them, the first device can be a first logical unit in the access network or a device (for example, a module, a communication module, a circuit, a chip (such as a modem chip, or a SoC chip or SIP chip containing a modem core), a chip system, or a processor) in the first logical unit. Among them, the first logical unit can be used for perception, or the first logical unit can be used for managing perception. The second device can be a second logical unit in the access network or a device (for example, a module, a communication module, a circuit, a chip (such as a modem chip, or a SoC chip or SIP chip containing a modem core), a chip system, or a processor) in the second logical unit. Optionally, the second logical unit can be used for communication, or the second logical unit can be used for managing communication. The third device can be a third logical unit in the access network or a device (for example, a module, a communication module, a circuit, a chip (such as a modem chip, or a SoC chip or SIP chip containing a modem core), a chip system, or a processor) in the third logical unit. The third device can be used for receiving and / or sending signals (for example, communication signals and / or perception signals).

[0119] For example, the first logical unit can be a sensing unit (SU) which can implement part of the functions of the base station. The second logical unit can include the CU and / or the DU. The third logical unit can be the RU. It should be understood that the SU can also have other names as long as it has the same function and is within the protection scope of the present application.

[0120] Optionally, in scenario 1, the first device and the sensing management network element can interact in various ways, for example, at least one of mode a1 to mode a8. Among them, the interaction mode of the control plane information between the first device and the sensing management network element and the interaction mode of the user plane (or data plane) information (such as sensing data) can be the same or different. The following takes the first device as an example to illustrate the SU.

[0121] Mode a1: The sensing management network element is an independent network element (for example, SF) in the core network. For example, as shown in (a) of FIG. 2, the sensing management network element is an SF. As shown in (a) of FIG. 2, the SU can directly interact with the SF; or, there is a direct connection between the SU and the SF, and the SU and the SF can interact through the direct connection. Optionally, in this mode, the control plane information and the user plane information between the SF and the SU can be transmitted through the direct connection.

[0122] Mode a2: The sensing management network element is an independent network element (for example, SF) in the core network. For example, as shown in (b) of FIG. 2, the sensing management network element is an SF. As shown in (b) of FIG. 2, the SU can interact with the SF through the core network device (for example, the AMF and / or the UPF in (b) of FIG. 2) and the second device (for example, the CU and / or the DU in (b) of FIG. 2) other than the SF. For example, the control plane information between the SU and the SF can be forwarded through the CU and the AMF; and / or, the user plane information between the SU and the SF can be forwarded through the CU and the UPF. For another example, the control plane information between the SU and the SF can be forwarded through the DU, the CU and the AMF; and / or, the user plane information between the SU and the SF can be forwarded through the DU, the CU and the UPF. For another example, the control plane information between the SU and the SF can be forwarded through the DU and the AMF; and / or, the user plane information between the SU and the SF can be forwarded through the DU and the UPF.

[0123] The manner a3: the perception management network element is an independent network element (for example, an SF) in the core network. The (c) in FIG. 2 illustrates the case that the perception management network element is an SF. As shown in the (c) in FIG. 2, the SU can interact with the SF through a second device (for example, the CU and / or the DU in the (c) in FIG. 2). For example, there is a direct connection between the SU and the CU; that is, the SU can be directly connected to the CU. The SU can interact with the SF through the CU. For another example, there is a direct connection between the SU and the DU; that is, the SU can be directly connected to the DU. The SU can interact with the SF through the DU. For yet another example, there is a direct connection between the SU and the DU; that is, the SU can be directly connected to the DU. The SU can interact with the SF through the DU and the CU. Optionally, in this manner, the interaction manner of the control plane information and the user plane information between the SU and the SF can be the same.

Optionally, in this manner, the control plane information and the user plane information between the SU and the perception server can be transmitted through the direct connection.

[0125] The manner a5: the perception management network element is a third-party server (referred to as a perception server in the (e) in FIG. 2). As shown in the (e) in FIG. 2, the SU can interact with the perception server through a core network device (for example, the AMF and / or the UPF in the (e) in FIG. 2) and a second device (for example, the CU and / or the DU in the (e) in FIG. 2). The core network device and the perception server can interact through an application programming interface (API). For example, the control plane information between the SU and the perception server can be forwarded through the CU and the AMF; and / or the user plane information between the SU and the perception server can be forwarded through the CU and the UPF. For another example, the control plane information between the SU and the perception server can be forwarded through the DU, the CU and the AMF; and / or the user plane information between the SU and the perception server can be forwarded through the DU, the CU and the UPF.

As shown in (f) in FIG. 2, the SU can interact with the perception server through a second device (exemplified by the CU and / or DU in (f) in FIG. 2). For example, there is a direct connection between the SU and the CU; that is, the SU can be directly connected to the CU. The SU can interact with the perception server through the CU. For another example, there is a direct connection between the SU and the DU; that is, the SU can be directly connected to the DU. The SU can interact with the perception server through the DU. For yet another example, there is a direct connection between the SU and the DU; that is, the SU can be directly connected to the DU. The SU can interact with the perception server through the DU and the CU. Optionally, in this manner, the interaction mode of the control plane information and the user plane information between the SU and the perception server can be the same.

[0127] The manner a7: the perception management network element can be a perception function device integrated in a core network device.

The following takes the first device as an SU and the third device as an RU as an example for description.

[0132] Mode b1: There is a direct connection between the SU and the CU; or in other words, the SU can be directly connected to the CU.

Optionally, in this option, both control plane information and user plane information between NodeC and the SF can be transmitted through the direct connection.

[0146] Option d2: The awareness management network element is a standalone network element in the core network (e.g., an SF). An example is shown in (b) of FIG. 5.

Optionally, in this option, the interaction mode of the control plane information and the user plane information between Node C and the awareness server can be the same.

[0151] Option d7: the awareness management network element can be an awareness function device integrated in a core network device. (g) of FIG. 5 illustrates an example in which the awareness management network element is an awareness function device integrated in an AMF and / or a UPF. As shown in (g) of FIG. 5, Node C can directly interact with the AMF and / or the UPF; or there is a direct connection between Node C and the AMF and / or the UPF, and Node C and the AMF and / or the UPF can interact through the direct connection. For example, the awareness-related control plane information between Node C and the AMF can be transmitted through the direct connection between Node C and the AMF; and / or the awareness-related user plane information (e.g., awareness data) between Node C and the UPF can be transmitted through the direct connection between Node C and the UPF.

[0152] Option d8: the awareness management network element can be an awareness function device integrated in a core network device.

As shown in (h) of FIG. 5, Node C can interact with the AMF and / or the UPF through a second device (illustrated as Node B in (h) of FIG. 5). For example, the awareness-related control plane information between Node C and the AMF can be forwarded through Node B; and / or the awareness-related user plane information (e.g., awareness data) between Node C and the UPF can be forwarded through Node B.

[0153] Optionally, in the case where Node C and the awareness management network element interact through option d2, option d5 or option d8, the second device and the AMF can include two types of interfaces, one type of interface can be used for communication, and the other type of interface can be used for awareness; or the second device and the AMF can include one interface, a part of the logical links on the interface can be used for communication, and the other part of the logical links can be used for awareness; or the second device and the AMF include one interface, and the data packets transmitted on the interface can contain or be associated with information indicating the type of data included in the data packets, such as awareness data, communication data or other data in addition to awareness data and communication data.

[0154] Optionally, in the case that the Node C and the awareness management network element interact through the manner d2, the manner d5 or the manner d8, the second device and the UPF can include two types of interfaces, one type of interface can be used for communication, and the other type of interface can be used for awareness; or, the second device and the UPF can include one interface, and a part of logical links on the interface can be used for communication, and the other part of logical links can be used for awareness; or, the second device and the UPF include one interface, and the data packets transmitted on the interface can contain or be associated with information used for indicating the type of data included in the data packets, the type of data including, for example, awareness data, communication data or other data than the awareness data and the communication data.

[0155] Optionally, in the scenario 2, the interaction manner between the second device and the awareness management network element can be various, for example, at least one of the manner e1 to the manner e5. Among them, the interaction manner of the control plane information and the interaction manner of the user plane (or referred to as the data plane) information (for example, awareness data) between the second device and the awareness management network element can be the same or different.

[0156] The manner e1: the awareness management network element is an independent network element (for example, an SF) in the core network. The (a) in FIG. 6 takes the SF as an example of the awareness management network element. As shown in the (a) in FIG. 6, the second device (taking the Node B as an example in the (a) in FIG. 6) can directly interact with the SF; or, there is a direct connection between the second device and the SF, and the second device and the SF can interact through the direct connection.

The (b) in FIG. 6 takes the SF as an example of the awareness management network element. As shown in the (b) in FIG. 6, the second device (taking the Node B as an example in the (b) in FIG. 6) can interact with the SF through the core network equipment (taking the AMF and / or the UPF as an example in the (b) in FIG. 6) other than the SF. For example, the control plane information between the Node B and the SF can be forwarded through the AMF; and / or, the user plane information between the Node B and the SF can be forwarded through the UPF.

[0158] The manner e3: the awareness management network element is a third-party server (referred to as an awareness server in the (c) in FIG. 6).

Optionally, in this manner, the interaction manner of the control plane information and the user plane information between the second device and the awareness server can be the same.

[0159] Way e4: The perception management network element can be a third party server (referred to as a perception server in (d) of FIG. 6). As shown in (d) of FIG. 6, the second device (exemplified by a NodeB in (d) of FIG. 6) can interact with the perception server through core network equipment (exemplified by an AMF and / or a UPF in (d) of FIG. 6). For example, control plane information between the NodeB and the perception server can be forwarded through the AMF; and / or, user plane information between the NodeB and the perception server can be forwarded through the UPF.

For example, control plane information related to perception between the NodeB and the AMF can be transmitted through the direct connection between the AMFs; and / or, user plane information (for example, perception data) related to perception between the NodeB and the UPF can be transmitted through the direct connection between the UPFs.

[0161] The communication system and service scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It can be known by those skilled in the art that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0162] The related terms involved in the embodiments of the present application will be explained first. It should be noted that these explanations are for the purpose of making the embodiments of the present application easier to understand, and should not be regarded as a limitation on the scope of protection required by the present application.

[0163] 1. Communication and perception integration:

[0164] The communication and perception integration technology is considered as one of the key technologies capable of expanding the service capability of a mobile communication network. The core idea of the communication and perception integration technology is to add perception capability on a mobile communication network, to build the capability of detecting, tracking and imaging a target, so as to make the communication and perception two capabilities coexist in a network, and to realize mutual benefit. Please refer to FIG. 7, which is a schematic diagram of a communication and perception integration scenario. In FIG. 7, the solid lines represent communication, and the dashed lines represent perception as an example. As shown in FIG. 7, the access network device can perceive other objects through self-transmission and self-reception, or can perceive other objects while communicating with the terminal. In FIG. 7, the terminal is an intelligent phone, the perception target is a drone, a pedestrian, and a vehicle as an example.

[0165] The perception technology can be generally divided into two modes: single-station perception and double-station perception. In the single-station perception mode, the transmitting device of the perception signal and the receiving device of the echo signal of the perception signal are the same device. In other words, in the single-station perception mode, the transmitting device not only transmits the perception signal, but also receives the echo signal of the perception signal reflected on the surface of the perception target. Therefore, the single-station perception mode can also be called the self-transmission and self-reception mode, without limitation. In the double-station perception mode, the transmitting device of the perception signal and the receiving device of the echo signal of the perception signal are different devices. In other words, the perception station A transmits the perception signal, and the echo signal of the perception signal reflected on the surface of the perception target is received by the perception station B. Therefore, the double-station perception mode can also be called the A-transmission and B-reception mode. The echo signal of the perception signal is obtained by the perception signal after the action (for example, reflection, diffraction or scattering, etc.) of the perception target, and therefore, the echo signal can still be called the perception signal, and the received perception signal can be replaced by the received echo signal of the perception signal.

[0166] Optionally, the single-station perception mode can be combined with the double-station perception mode. For example, a part of nodes adopt the single-station perception mode, and another part of nodes adopt the double-station perception mode. For another example, a certain node adopts the single-station perception mode in a period of time, and adopts the double-station perception mode in another period of time. For another example, in a period of time, a certain node adopts both the single-station perception mode and the double-station perception mode. The combination of the single-station perception mode and the double-station perception mode can also be called the hybrid transmission and reception mode; or the combination of the self-transmission and self-reception mode and the A-transmission and B-reception mode can also be called the hybrid transmission and reception mode.

[0167] FIG. 8 shows a schematic diagram of a sensing scenario to which embodiments of the present application can be applied. Eight sensing scenarios to which embodiments of the present application can be applied are provided in FIG. 8, which are respectively: a scenario in which an access network device A self-transmits and self-receives, i.e., a scenario in which the access network device A transmits a sensing signal and receives a return signal, as shown in (1) of FIG. 8; a scenario in which a terminal A self-transmits and self-receives, i.e., a scenario in which the terminal A transmits a sensing signal and receives a return signal, as shown in (2) of FIG. 8; a scenario in which the access network device A transmits a sensing signal and the access network device B receives a return signal, as shown in (3) of FIG. 8; a scenario in which the terminal A transmits a sensing signal and the terminal B receives a return signal, as shown in (4) of FIG. 8; a scenario in which the access network device A transmits a sensing signal and the terminal A receives a return signal, as shown in (5) of FIG. 8; a scenario in which the terminal A transmits a sensing signal and the access network device A receives a return signal, as shown in (6) of FIG. 8; a scenario in which the access network device A transmits a sensing signal and the access network device B receives a return signal under control of an access network device C, as shown in (7) of FIG. 8; and a scenario in which the terminal A transmits a sensing signal and the terminal B receives a return signal under control of the access network device A, as shown in (8) of FIG. 8. In FIG. 8, a vehicle is taken as an example of a sensing target, and a smartphone is taken as an example of a terminal.

[0168] The sensing target can also be referred to as a target, a detected target, a sensed object, a detected object, or a sensed device, without limitation. The sensing target can be various tangible objects in an environment that can reflect, diffract, or scatter electromagnetic waves. For example, the sensing target can be a stationary object such as a mountain, a forest, or a building. For another example, the sensing target can also be a movable object such as a vehicle, a drone, a pedestrian, or a terminal. Embodiments of the present application do not limit the specific implementation form of the sensing target.

[0169] The sensing result can also be referred to as a detected result, a detected data, or a sensed data, without limitation. The sensing result can be a result obtained by processing, by a receiving end device, a return signal. For example, the sensing result can include at least one of a position of the sensing target, a speed of the sensing target, a distance from the sensing target to the receiving end device, a distance from the sensing target to a transmitting end device, a direction or an angle of the sensing target, or a strength of the return signal.

[0170] 2. In the present application, a time unit can be an absolute time, or can be a unit of a time domain resource. For example, the time unit can include at least one of a system frame, a subframe, a millisecond (ms), a slot, or a symbol.

[0171] The frequency unit can be an absolute frequency or a unit of frequency domain resource. For example, the frequency unit can include at least one of a subcarrier, a resource element (RE), a resource block (RB), a resource block group (RBG), etc.

[0172] 3. In the present application, "indicate" or "for indicating" can include explicit indication (or direct indication) and implicit indication (or indirect indication). When describing that a certain information is for indicating A, it can include that the information explicitly indicates A or implicitly indicates A, and does not mean that A must be carried in the information.

[0173] The indication manner involved in the embodiments of the present application should be understood as covering various methods that can enable the to-be-indicated party to know the to-be-indicated information. The to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending occasion of the sub-information can be the same or different, which is not limited.

[0174] The "information" in the embodiments of the present application can be explicitly indicated, i.e., directly indicated through signaling, or obtained according to the parameters indicated by the signaling, in combination with other rules or in combination with other parameters or through derivation. Or it can be implicitly indicated, i.e., obtained according to rules or relationships, or according to other parameters, or through derivation. It is not limited.

[0175] 4. In the present application, the communication between different devices can mean direct communication between different devices (i.e., without the need for other devices to transfer or forward), or can mean communication between different devices through other devices (i.e., with the need for other devices to transfer or forward), or can mean that a functional unit inside a device communicates with other devices through another functional unit. For example, "sending information to (a terminal)" can be understood as that the destination of the information is the terminal, which can include directly or indirectly sending information to the terminal. "Receiving information from (a terminal)" can be understood as that the source of the information is the terminal, which can include directly or indirectly receiving information from the terminal. The information can be processed between the source and the destination of the information sending, such as format conversion, digital-to-analog conversion, amplification, filtering, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly, which will not be repeated here.

[0176] 5. In the present application, the words "exemplarily", "such as", "for example", and "examples of" are used to represent examples, illustrations or descriptions, and are not used to limit the protection scope of the present application, and it should be understood that the examples in the present application can also be implemented in other ways.

[0177] 6、In this application, any two of the programs, instructions and codes can be replaced with each other.

[0178] Currently, in the ISAC system, the core network device SF mainly manages the sensing task and processes the sensing data. For example, the SF can provide the access network device with the configuration for sensing according to the sensing requirement from the AF. For example, the SF can configure the sensing resource for the access network device according to the sensing requirement from the AF. After the SF obtains the sensing data from the access network device, the SF can process the sensing data and send the processed sensing result to the AF.

[0179] However, by this method, the efficiency of sensing management is low. On the one hand, it is difficult for the SF to obtain the state of the access network side, for example, the SF cannot obtain the usage of the resource of the access network side in real time. In this way, the sensing resource configured by the SF for the access network device can not be suitable, thereby resulting in that the sensing requirement is not met, for example, the sensing QoS or SLA in the sensing requirement is not met. On the other hand, the communication function and the sensing function of the access network side are integrated together, resulting in poor expansibility, for example, if the sensing function needs to be upgraded, the communication function also needs to be upgraded together, thereby it is difficult to meet higher sensing requirement.

[0180] How to improve the efficiency of sensing management needs further research.

[0181] Embodiments of the present application provide a communication method. FIG. 9 is a flowchart of the communication method provided by the embodiments of the present application.

[0182] In FIG. 9, the sensing management network element, the first device of the access network side and the second device of the access network side are taken as an example to illustrate the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, the sensing management network element can be replaced by a device (for example, a module, a communication module, a circuit, a chip (such as a modem chip, or a SoC chip or a SIP chip containing a modem core), a chip system or a processor) in the sensing management network element, or can be replaced by a logical node, a logical module or software which can realize all or part of the function of the sensing management network element.

[0183] In some examples, the awareness management network element can be a core network device. For example, the awareness management network element is a standalone network element in the core network, such as an SF. In this case, the SF can also be referred to as other names, such as an awareness management function, as long as it has the same function, which is within the protection scope of the present application. For another example, the awareness management network element can be integrated in a device with the core network device, such as the awareness management network element can be an integrated awareness function device in the core network device, or the awareness management network element and the core network device can be different devices in one device. The core network device can be, for example, an AMF and / or a UPF. In other examples, the awareness management network element can be a third-party server. Optionally, the third-party server can be outside the core network, or the third-party server can not be a core network device. It should be understood that the awareness management network element can have other names, such as an awareness network element, an awareness server, or an awareness network element / server, as long as it has the same function, which is within the protection scope of the present application.

[0184] As shown in FIG. 9, the method includes:

[0185] S901: The first device can receive first information.

[0186] The first information can indicate a first awareness requirement. The present application does not limit the specific manner in which the first information indicates the first awareness requirement.

[0187] In some possible manners, the awareness management network element can send the first information, and accordingly, the first device can receive the first information from the awareness management network element, as shown in S901a. In this way, the first device can obtain the first awareness requirement from the awareness management network element.

[0188] In other possible manners, the second device can send the first information, and accordingly, the first device can receive the first information from the second device, as shown in S901b. For example, in the scenario 1 in the above, in the case that the first device is the first logical unit and the second device is the second logical unit, the first logical unit can receive the first information from the second logical unit. For another example, in the scenario 2 in the above, in the case that the first device is the first access network device and the second device is the second access network device, the first access network device can receive the first information from the second access network device. In this way, the first device can obtain the first awareness requirement from the second device on the access network side, thereby improving the management efficiency of the access network for awareness and reducing the time delay of obtaining the first awareness requirement.

[0189] Optionally, the first awareness requirement includes at least one of the following information, or in other words, the first information indicates at least one of the following information: awareness QoS or SLA; type of awareness data; time of awareness; or, area of awareness. The specific content is as follows:

[0190] 1. Sensing QoS or SLA: can be used to indicate the required QoS or SLA for sensing. For example, the sensing QoS or SLA can include at least one of the following information: coverage, accuracy, resolution, detection / false alarm probability, service latency, or refresh rate. The coverage can be a limit on the distance and / or range that can be detected; the accuracy can be the difference between the sensing result and the actual data, e.g., one or more of the distance difference, angle difference, or speed difference; the resolution can be the minimum difference of different sensing results in one or more of the dimensions of distance, angle, or speed; the detection / false alarm probability refers to the probability of detecting the presence or absence of a target; the service latency refers to the time interval between the occurrence or triggering of sensing and the output of the sensing result; and the refresh rate can be the rate of refreshing of the sensing data (e.g., positioning data).

[0191] 2. Type of sensing data: can be used to indicate the type of data to be sensed. For example, the type of sensing data can include at least one of the following: I / Q signal, RAV spectrum information, CFR information, point cloud information, or sensing target information. Various possible ways of indicating the type of sensing data are provided herein, so that the type of sensing data can be flexibly configured.

[0192] 3. Time of sensing: can be used to indicate the time of sensing. For example, if the time of sensing included in the first sensing requirement is a first time period, it means that sensing is to be performed within the first time period. The time of sensing can be an absolute time, or a relative time with respect to a reference time, without limitation.

[0193] 4. Area of sensing: can be used to indicate the area of sensing. For example, if the area of sensing indicated by the first information is a first area, it means that sensing is to be performed in the first area, or that targets in the first area are to be sensed. Optionally, the area of sensing can be indicated in various ways. In some examples, the area of sensing can be indicated by the coordinates of the area. In other examples, the area of sensing can be indicated by an administrative region, e.g., if the administrative region is City A, it means that sensing is to be performed within the scope of City A. In yet other examples, the area of sensing can be indicated by the identity of one or more cells, e.g., if the identity of the one or more cells includes the identity of Cell #1 and Cell #2, it means that sensing is to be performed within the coverage (or service range) of Cell #1 and Cell #2. The area of sensing can be replaced by at least one of the following: range of sensing or location of sensing.

[0194] The method provides various possible ways of indicating the sensing requirement, so that the sensing requirement can be flexibly configured.

[0195] The first information can also have other names, such as sensing service information or sensing requirement information, as long as it has the same function and is within the protection scope of the present application.

[0196] S902: The first device can send the second information.

[0197] In some possible manners, the second device can receive the second information, as shown in S902a. For example, in scenario 1 in the above, in the case that the first device is the first logical unit and the second device is the second logical unit, the first logical unit can send the second information to the second logical unit. For another example, in scenario 2 in the above, in the case that the first device is the first access network device and the second device is the second access network device, the first access network device can send the second information to the second access network device.

[0198] The second information can be used to determine the first sensing resource. The first sensing resource can be used for receiving and / or sending, by the access network side, the sensing signal. For example, in scenario 1 in the above, the first sensing resource can be used for, or be, a resource for receiving and / or sending, by the third device (e.g., the third logical unit (such as a RU)), the sensing signal. For another example, in scenario 2 in the above, the first sensing resource can be used for, or be, a resource for receiving and / or sending, by the second device (e.g., the second access network device (such as a NodeB)), the sensing signal.

[0199] Optionally, the receiving and / or sending of the sensing signal can correspond to (or be related to or associated with) the second sensing requirement; or the receiving and / or sending of the sensing signal can be used to implement the second sensing requirement. The second sensing requirement is determined according to the first sensing requirement; or the second sensing requirement corresponds to (or is related to or associated with) the first sensing requirement.

[0200] In some examples, the second sensing requirement can be the first sensing requirement.

[0201] In some examples, the second awareness requirement can include part of the first awareness requirement; or, the second awareness requirement can be a sub-requirement of the first awareness requirement; or, the second awareness requirement can be a result of the first awareness requirement being split (or divided) by the first device. For example, in the first awareness requirement, the area to be sensed includes the coverage of cell #1 and the coverage of cell #2. Cell #1 is a cell of CU #1, and cell #2 is a cell of CU #2. The first awareness requirement can be split into a second awareness requirement #1 and a second awareness requirement #2. In the second awareness requirement #1, the area to be sensed includes the coverage of cell #1; and in the second awareness requirement #2, the area to be sensed includes the coverage of cell #2. For another example, in the first awareness requirement, the area to be sensed includes the coverage of cell #1 and the coverage of cell #2. Cell #1 is a cell of NodeB #1, and cell #2 is a cell of NodeB #2. The first awareness requirement can be split into a second awareness requirement #1 and a second awareness requirement #2. In the second awareness requirement #1, the area to be sensed includes the coverage of cell #1; and in the second awareness requirement #2, the area to be sensed includes the coverage of cell #2. For yet another example, in the first awareness requirement, the time to be sensed includes time period #1 and time period #2. The traffic volume of cell #1 in time period #1 is less than (or less than or equal to) a traffic volume threshold, and the traffic volume of cell #2 in time period #2 is less than (or less than or equal to) the traffic volume threshold. The first awareness requirement can be split into a second awareness requirement #3 and a second awareness requirement #4. In the second awareness requirement #3, the time to be sensed includes time period #1, and the area to be sensed includes the coverage of cell #1; and in the second awareness requirement #4, the time to be sensed includes time period #2, and the area to be sensed includes the coverage of cell #2. The traffic volume threshold can be pre-set, e.g., specified by a protocol; or determined by the first device; or notified to the first device by another device (e.g., a core network device).

[0202] The specific content of the second awareness requirement can refer to the description of the first awareness requirement in S901, except that the first awareness requirement is replaced by the second awareness requirement, which will not be repeated here.

[0203] In the method shown in FIG. 9, after receiving the first information indicating the first awareness requirement, the first device at the access network side can send second information for determining the first awareness resource. In this way, the first awareness resource can be determined at the access network side. Since the device at the access network side can conveniently obtain the condition of the resource at the access network side, the awareness resource that is suitable for the condition at the access network side can be determined, and thus the awareness requirement can be met, the awareness performance can be improved, and the efficiency of awareness management can be improved.

[0204] In addition, the device at the access network side can quickly acquire the resource status at the access network side, thereby reducing the time delay for determining the sensing resource, and improving the sensing performance and the efficiency of the sensing management.

[0205] In addition, in the method, the first device can be used for sensing, and the first device can be independent of the second device and / or the third device used for communication, thereby improving the scalability of the first device, and thereby meeting higher sensing requirements by upgrading the first device.

[0206] As described above, the second information can be used to determine the first sensing resource, and there are various ways to determine, for example, the way f1 or the way f2.

[0207] Way f1: The second information can indicate the first sensing resource. The present application does not limit the specific content of the second information indicating the first sensing resource.

[0208] For example, the first sensing resource can include at least one of the following: time domain resource, frequency domain resource, space domain resource, code domain resource, or power domain resource.

[0209] Optionally, in this way, the first sensing resource can be determined by the first device. For example, the first sensing resource can be determined by the first device according to the second sensing requirement. The present application does not limit the specific way of determining the first sensing resource by the first device according to the second sensing requirement.

[0210] The second information can also have other names, such as sensing resource configuration information, etc., as long as it has the same function, which is within the protection scope of the present application.

[0211] In this way, the second device can accurately determine the first sensing resource according to the second information. In this way, the sensing resource can be determined by the first device at the access network side, thereby improving the flexibility of the first device for sensing management, and thereby improving the efficiency of the sensing management.

[0212] In some implementations, in the way f1, the method shown in FIG. 9 can further include step A1:

[0213] Step A1: The second device can send third information; correspondingly, the first device can receive the third information.

[0214] The third information can indicate the recommended and / or non-recommended (preferred and / or non-preferred) sensing resource. Optionally, the recommended and / or non-recommended sensing resource can be the sensing resource recommended and / or not recommended by the second device. For example, the recommended and / or non-recommended sensing resource can include at least one of the following: time domain resource, frequency domain resource, space domain resource, code domain resource, or power domain resource.

[0215] Optionally, the third information can be used to determine the first sensing resource; or the first device can determine the first sensing resource according to the third information.

[0216] In some examples, the third information indicates recommended sensing resources; the first resource can belong to the recommended sensing resources, or the first device can select the first sensing resource from the recommended sensing resources. For example, if the recommended sensing resources indicated by the third information are time-domain resources on time unit #1 and time unit #2, the first sensing resource can include time-domain resources on time unit #1 and / or time unit #2. For another example, if the recommended sensing resources indicated by the third information are frequency-domain resources on frequency unit #1 and frequency unit #2, the first sensing resource can include frequency-domain resources on frequency unit #1 and / or frequency unit #2.

[0217] In other examples, the third information indicates non-recommended sensing resources; the first sensing resource can be a resource other than the non-recommended sensing resources, or the first sensing resource can be a resource other than the non-recommended sensing resources from resources supported by the second device, or the first device can select the first sensing resource from the resources other than the non-recommended sensing resources, or the first device can select the first sensing resource from the resources other than the non-recommended sensing resources from the resources supported by the second device. For example, if the non-recommended sensing resources indicated by the third information are time-domain resources on time unit #1 and time unit #2, the first sensing resource can include part or all of the time-domain resources other than the time-domain resources on time unit #1 and time unit #2. For another example, if the non-recommended sensing resources indicated by the third information are frequency-domain resources on frequency unit #1 and frequency unit #2, the first sensing resource can include part or all of the frequency-domain resources other than the frequency-domain resources on frequency unit #1 and frequency unit #2. For another example, if the non-recommended sensing resources indicated by the third information are time-domain resources on time unit #1 and time unit #2, and the resources supported by the second device include time-domain resources on time unit #1 to time unit #4, the first sensing resource can include time-domain resources on time unit #3 and / or time unit #4. For another example, if the non-recommended sensing resources indicated by the third information are frequency-domain resources on frequency unit #1 and frequency unit #2, and the resources supported by the second device include frequency-domain resources on frequency unit #1 to frequency unit #4, the first sensing resource can include frequency-domain resources on frequency unit #3 and / or frequency unit #4.

[0218] In yet some examples, the third information indicates recommended sensing resources and non-recommended sensing resources. The first sensing resource can belong to the recommended sensing resources and not belong to the non-recommended sensing resources. For example, if the third information indicates that the recommended sensing resources are time-domain resources on time unit #1 and time unit #2, and the non-recommended sensing resources are time-domain resources on time unit #3 and time unit #4, the first sensing resource can include time-domain resources on time unit #1 and / or time unit #2. For another example, if the third information indicates that the recommended sensing resources are frequency-domain resources on frequency unit #1 and frequency unit #2, and the non-recommended sensing resources are frequency-domain resources on frequency unit #3 and frequency unit #4, the first sensing resource can include frequency-domain resources on frequency unit #1 and / or frequency unit #2.

[0219] The third information can also have other names as long as it has the same function and is within the scope of the present application.

[0220] Optionally, step A1 can be before S902. The present application does not limit the execution order of step A1 and S901. In S901, in the case that the first device receives the first information from the second device, the first information and the third information can be carried in the same message or in different messages.

[0221] Through the implementation, the first device can learn the recommended and / or non-recommended sensing resources, so as to select appropriate sensing resources accordingly, and thus better meet the sensing requirements and improve the efficiency of sensing management.

[0222] In other implementations, in mode f1, the method shown in FIG. 9 can further include step A2:

[0223] Step A2: The second device can send first response information; correspondingly, the first device can receive the first response information.

[0224] The first response information can indicate acceptance or rejection of the first sensing resource for implementing the second sensing requirement. Optionally, “the first sensing resource for implementing the second sensing requirement” can be replaced by at least one of the following: configuration (or scheduling or indication) of the first sensing resource; configuration (or scheduling or indication) of the second information; or, the first sensing resource for receiving and / or sending of the sensing signal on the access network side. “Acceptance or rejection” can be replaced by at least one of the following: whether to accept, whether to agree or whether to reject. Through the method, the first device can accurately determine whether the second device accepts or rejects the first sensing resource for implementing the second sensing requirement according to the first response information.

[0225] Optionally, in case the first response information indicates that the first sensing resource is rejected for implementing the second sensing demand, the first response information can further indicate at least one of: a reason for the rejection, or recommended and / or non-recommended sensing resource. This is explained in detail as follows.

[0226] 1. The reason for the rejection: used to indicate the reason for rejecting the first sensing resource for implementing the second sensing demand. Optionally, the reason can be indicated by a cause value.

[0227] For example, the reason can include at least one of the following reasons a1 to a5:

[0228] Reason a1: Insufficient sensing time domain resource. For example, in the scenario 1 above, the first device can be a first logical unit (e.g., a SU) in an access network or a device in the first logical unit, the second device can be a second logical unit (e.g., a CU and / or a DU) in the access network or a device in the second logical unit, and the third device can be a third logical unit (e.g., an RU) in the access network or a device in the third logical unit. The available sensing time domain resource of the second device and / or the third device is less than the time domain resource in the first sensing resource. For another example, in the scenario 2 above, the first device can be a first access network equipment (e.g., a NodeC) or a device in the first access network equipment, and the second device can be a second access network equipment (e.g., a NodeB) or a device in the second access network equipment. The available sensing time domain resource of the second device is less than the time domain resource in the first sensing resource.

[0229] Reason a2: Insufficient sensing frequency domain resource. For example, in the scenario 1 above, the available sensing frequency domain resource of the second device and / or the third device is less than the frequency domain resource in the first sensing resource. For another example, in the scenario 2 above, the available sensing frequency domain resource of the second device is less than the frequency domain resource in the first sensing resource.

[0230] Reason a3: Insufficient sensing spatial domain resource. For example, in the scenario 1 above, the available sensing spatial domain resource of the second device and / or the third device is less than the spatial domain resource in the first sensing resource. For another example, in the scenario 2 above, the available sensing spatial domain resource of the second device is less than the spatial domain resource in the first sensing resource.

[0231] Reason a4: Insufficient sensing code domain resource. For example, in the scenario 1 above, the available sensing code domain resource of the second device and / or the third device is less than the code domain resource in the first sensing resource. For another example, in the scenario 2 above, the available sensing code domain resource of the second device is less than the code domain resource in the first sensing resource.

[0232] Cause a5: insufficient available sensing power domain resources. For example, in scenario 1 above, the available sensing power domain resources of the second device and / or the third device are less than the power domain resources in the first sensing resource. For another example, in scenario 2 above, the available sensing power domain resources of the second device are less than the power domain resources in the first sensing resource.

[0233] 2. Recommended and / or non-recommended sensing resource: the specific content can refer to the description of the recommended and / or non-recommended sensing resource in step A1, which will not be repeated here.

[0234] Through the method, the first device can obtain the cause of rejecting the first sensing resource for implementing the second sensing requirement and / or the recommended and / or non-recommended sensing resource, so as to adjust the second information accordingly, for example, the sensing requirement indicated by the second information and / or the sensing resource configured for the second device can be adjusted, so that the adjusted second information (or the sensing resource determined according to the adjusted second information) is adapted to the resource situation on the second device side, and then the sensing requirement can be met, the sensing performance can be improved, and the efficiency of sensing management can be improved.

[0235] Optionally, in the case where the first response information indicates that the first sensing resource is rejected for implementing the second sensing requirement, the first device can re-execute S902.

[0236] In some implementations, the first device can send the second information to another second device. For example, the first device is a first logical unit. The first logical unit receives the first response information #1 from CU#1 after sending the second information to CU#1, and the first response information #1 indicates that the first sensing resource is rejected for implementing the second sensing requirement. The first logical unit can send the second information to CU#2, and the RU managed by CU#2 can implement the second sensing requirement. For another example, the first device is a first access network device. The first access network device receives the first response information #1 from NodeB#1 after sending the second information to NodeB#1, and the first response information #1 indicates that the first sensing resource is rejected for implementing the second sensing requirement. The first access network device can send the second information to NodeB#2, and NodeB#2 can implement the second sensing requirement.

[0237] In some other implementations, the first device can send the updated second information to the second device. The updated second information can be determined according to the reason for rejection, and / or the recommended and / or un-recommended sensing resources; or the updated second information can correspond to (or be related to or associated with) the reason for rejection, and / or the recommended and / or un-recommended sensing resources. The following is an example in which the sensing resources indicated by the updated second information are first sensing resources #1, and the sensing resources indicated by the second information before being updated are first sensing resources #2. For example, in the case where the reason for rejection includes insufficient time domain resources for sensing, the time domain resources in the first sensing resources #1 can be less than the time domain resources in the first sensing resources #2; or in the case where the reason for rejection includes insufficient time domain resources for sensing, the first device can reduce the time domain resources in the first sensing resources. For another example, the first sensing resources #2 include un-recommended sensing resources, and the first sensing resources #1 do not include un-recommended sensing resources. For yet another example, the first sensing resources #2 do not belong to recommended sensing resources, and the first sensing resources #1 belong to recommended sensing resources.

[0238] The first response information can have other names, such as first feedback information, sensing resource configuration response message, sensing resource configuration completion / success message (in the case of indicating acceptance of the first sensing resources for implementing the second sensing requirement), or sensing resource configuration failure / rejection message (in the case of indicating rejection of the first sensing resources for implementing the second sensing requirement). As long as they have the same function, they are within the protection scope of the present application.

[0239] Optionally, the step A2 can be after S902.

[0240] Optionally, the step A1 and the step A2 can be independent or combined.

[0241] Optionally, in the manner f1, the second information can further indicate at least one of the following: a transceiving mode for sensing; or a sensing area. The following is a specific description.

[0242] 1. The transceiving mode for sensing: for example, the transceiving mode can be one of the following: self-transceiving mode, A-transceiving-B mode, or hybrid transceiving mode. For specific content, reference can be made to the description of the self-transceiving mode, the A-transceiving-B mode, and the hybrid transceiving mode in the above term explanation part, which will not be repeated here.

[0243] 2. The sensing area: for specific content, reference can be made to the description of the “sensing area” in the first sensing requirement in S901, which will not be repeated here. In some examples, the sensing area indicated by the second information can be the same as the sensing area in the first sensing requirement. In some other examples, the sensing area indicated by the second information can be different from the sensing area in the first sensing requirement. For example, the sensing area indicated by the second information can belong to the sensing area in the first sensing requirement.

[0244] In this way, the second device can accurately determine the sensing mode and / or the sensing area according to the second information, so as to improve the sensing performance. In addition, in this way, the sensing mode and / or the sensing area can be indicated by the first device, so as to improve the flexibility of the first device in sensing management.

[0245] Optionally, the second information can indicate a second sensing requirement.

[0246] The specific content of the second sensing requirement can refer to the description of the second sensing requirement in S902, and will not be repeated here.

[0247] Optionally, the second sensing requirement can be used to determine the first sensing resource; or, the second device can determine the first sensing resource according to the second sensing requirement; or, the second sensing requirement corresponds to (or is related to or associated with) the first sensing resource.

[0248] In some possible manners, the second information can further indicate the sensing mode. The specific content of the sensing mode can refer to the description of the sensing mode in manner f1, and will not be repeated here.

[0249] In this way, the second device can determine the first sensing resource matched with the second sensing requirement according to the second sensing requirement indicated by the second information. In addition, in this way, the sensing resource can be determined by the second device on the access network side, so as to improve the flexibility of the second device in sensing management, and further improve the efficiency of the sensing management.

[0250] In some implementations, in manner f2, the method shown in FIG. 9 can further include step B1:

[0251] Step B1: The second device can send second response information; correspondingly, the first device can receive the second response information.

[0252] In some implementations, the second response information can indicate the first sensing resource. For example, the first sensing resource can include at least one of the following: a time domain resource, a frequency domain resource, a space domain resource, a code domain resource, or a power domain resource. In this way, the first device can accurately determine the first sensing resource according to the second response information.

[0253] Optionally, in this implementation, the second response information can further indicate at least one of the following: the sensing mode; or, the sensing position. The specific content will be described below.

[0254] 1. The sensing transceiving mode: details can be referred to the description of the sensing transceiving mode in the manner f1, and will not be repeated. In some examples, the sensing transceiving mode indicated by the second response information can be the same as the sensing transceiving mode indicated by the second information. In other examples, the sensing transceiving mode indicated by the second response information can be different from the sensing transceiving mode indicated by the second information. For example, the sensing transceiving mode indicated by the second response information can belong to the sensing transceiving mode indicated by the second information. For example, the sensing transceiving mode indicated by the second information includes the self-transmitting and self-receiving mode and the A-transmitting and B-receiving mode, and the sensing transceiving mode indicated by the second response information can include the self-transmitting and self-receiving mode and / or the A-transmitting and B-receiving mode.

[0255] 2. The sensing area: details can be referred to the description of the "sensing area" in the first sensing requirement in S901, and will not be repeated. In some examples, the sensing area indicated by the second response information can be the same as the sensing area in the second sensing requirement. In other examples, the sensing area indicated by the second response information can be different from the sensing area in the second sensing requirement. For example, the sensing area indicated by the second response information can belong to the sensing area in the second sensing requirement.

[0256] Optionally, the step B1 can be after S902.

[0257] Through the method, the second response information can accurately indicate the sensing transceiving mode and / or the sensing area, so as to improve the efficiency of sensing management and improve the sensing performance.

[0258] In other implementations, the second response information can indicate that the second sensing requirement is refused (or disagreed or not accepted). Through the implementation, the first device can accurately determine that the second device refuses to implement the second sensing requirement according to the second response information.

[0259] Optionally, in the implementation, the second response information can further indicate at least one of the following: a reason for refusal; recommended and / or non-recommended sensing resources; or, implementable sensing requirements. Details are described below.

[0260] 1. The reason for refusal: used to indicate the reason for refusing to implement the second sensing requirement. Optionally, the reason can be indicated by a cause value.

[0261] For example, the reason can include at least one of the following reasons b1 to b6:

[0262] Cause b1: insufficient sensing time-domain resources. For example, in scenario 1 above, the first device can be a first logical unit (e.g., a SU) in an access network or a device in the first logical unit, the second device can be a second logical unit (e.g., a CU and / or a DU) in the access network or a device in the second logical unit, and the third device can be a third logical unit (e.g., a RU) in the access network or a device in the third logical unit. The available sensing time-domain resources of the second device and / or the third device do not satisfy the second sensing requirement. Also for example, in scenario 2 above, the first device can be a first access network equipment (e.g., a Node C) or a device in the first access network equipment, and the second device can be a second access network equipment (e.g., a Node B) or a device in the second access network equipment. The available sensing time-domain resources of the second device do not satisfy the second sensing requirement.

[0263] Cause b2: insufficient sensing frequency-domain resources. For example, in scenario 1 above, the available sensing frequency-domain resources of the second device and / or the third device do not satisfy the second sensing requirement. Also for example, in scenario 2 above, the available sensing frequency-domain resources of the second device do not satisfy the second sensing requirement.

[0264] Cause b3: insufficient sensing space-domain resources. For example, in scenario 1 above, the available sensing space-domain resources of the second device and / or the third device do not satisfy the second sensing requirement. Also for example, in scenario 2 above, the available sensing space-domain resources of the second device do not satisfy the second sensing requirement.

[0265] Cause b4: insufficient sensing code-domain resources. For example, in scenario 1 above, the available sensing code-domain resources of the second device and / or the third device do not satisfy the second sensing requirement. Also for example, in scenario 2 above, the available sensing code-domain resources of the second device do not satisfy the second sensing requirement.

[0266] Cause b5: insufficient sensing power-domain resources. For example, in scenario 1 above, the available sensing power-domain resources of the second device and / or the third device do not satisfy the second sensing requirement. Also for example, in scenario 2 above, the available sensing power-domain resources of the second device do not satisfy the second sensing requirement.

[0267] Cause b6: the second device does not satisfy a sensing QoS or SLA in the second sensing requirement.

[0268] 2. Recommended and / or non-recommended sensing resources: the specific content can refer to the description of the recommended and / or non-recommended sensing resources in step A1, which will not be repeated here.

[0269] 3. Achievable sensing requirement: or called satisfied sensing requirement. Optionally, the achievable sensing requirement can be a sensing requirement that can be achieved by the second device, for example, a sensing QoS or SLA that can be satisfied by the second device.

[0270] Through the method, the first device can learn the reason for the rejection of the second sensing requirement, the recommended and / or non-recommended sensing resource, or one or more of the implementable sensing requirements, so as to adjust the sensing requirement for the second device accordingly, so that the adjusted sensing requirement is adapted to the resource condition on the second device side, and thus the sensing requirement can be met, the sensing performance is improved, and the efficiency of sensing management is improved.

[0271] Optionally, in the case where the second response information indicates that the second sensing requirement is rejected, the first device can re-execute S902.

[0272] In some implementations, the first device can send the second information to another second device. For example, the first device is a first logical unit. The first logical unit receives the second response information #1 from the CU#1 after sending the second information to the CU#1, and the second response information #1 indicates that the second sensing requirement is rejected. The first logical unit can send the second information to the CU#2, and the RU managed by the CU#2 can implement the second sensing requirement. For another example, the first device is a first access network device. The first access network device receives the second response information #1 from the NodeB#1 after sending the second information to the NodeB#1, and the second response information #1 indicates that the second sensing requirement is rejected. The first access network device can send the second information to the NodeB#2, and the NodeB#2 can implement the second sensing requirement.

[0273] In other implementations, the first device can send the updated second information to the second device. The updated second information can be determined according to or correspond to (or be related to or associated with) at least one of the following: the reason for the rejection; the recommended and / or non-recommended sensing resource; or the implementable sensing requirement. The following is an example in which the sensing requirement indicated by the updated second information is the second sensing requirement #1, and the sensing requirement indicated by the second information before the update is the second sensing requirement #2. For example, in the case where the reason for the rejection includes insufficient sensing time domain resources, the sensing time domain resources required by the second sensing requirement #1 can be less than the sensing time domain resources required by the second sensing requirement #2; or in the case where the reason for the rejection includes insufficient sensing time domain resources, the first device can reduce the time domain resources required by the second sensing requirement. For another example, the sensing resources required by the second sensing requirement #2 include non-recommended sensing resources, and the sensing resources required by the second sensing requirement #1 do not include non-recommended sensing resources. For another example, the sensing resources required by the second sensing requirement #2 do not belong to the recommended sensing resources, and the sensing resources required by the second sensing requirement #1 belong to the recommended sensing resources. For another example, the second sensing requirement #2 does not belong to the implementable sensing requirements of the second device, and the second sensing requirement #1 belongs to the implementable sensing requirements of the second device.

[0274] The second response information can have other names, such as second feedback information, a sensing resource configuration response message, a sensing resource configuration completion / success message (in the case of indicating the first sensing resource), or a sensing resource configuration failure / rejection message (in the case of indicating rejection of implementing the second sensing requirement). As long as they have the same function, they are within the protection scope of the present application.

[0275] In some possible manners, the first sensing resource can be used for the third device to receive and / or transmit the sensing signal, which can be applicable to the above scenario 1. In this case, the third device can determine the first sensing resource in various manners, such as manner g1 or manner g2.

[0276] Manner g1: The third device can receive the second information, as shown in S902b. For example, in the above scenario 1, in the case where the first device is the first logical unit and the third device is the third logical unit, the first logical unit can send the second information to the third logical unit.

[0277] The second information can indicate the first sensing resource, and details can be referred to manner f1, which will not be repeated here.

[0278] Optionally, after receiving the second information, the third device can receive and / or transmit the sensing signal according to the first sensing resource.

[0279] In this manner, the third device can accurately determine the first sensing resource according to the second information. Moreover, in this manner, the sensing resource can be notified to the third device by the first device on the access network side, thereby improving the flexibility of the first device in sensing management, and further improving the efficiency of the sensing management.

[0280] Optionally, S902a and S902b can coexist. In the case where S902a and S902b coexist, S902a and S902b can occur at the same time, or S902b can be after S902a; the second information in S902a and the second information in S902b can be carried in the same message or in different messages.

[0281] Optionally, in manner g1, the second information can further indicate at least one of the following: a transceiving mode for sensing; or a sensing area. Details are as follows.

[0282] 1. Transceiving mode for sensing: details can be referred to the description of the transceiving mode for sensing in manner f1, which will not be repeated here.

[0283] Exemplarily, the third device can receive and / or transmit the sensing signal according to the sensing mode indicated by the second information. For example, in the case that the sensing mode is the self-transmitting and self-receiving mode, the third device can transmit the sensing signal according to the first sensing resource, and receive the sensing signal. For another example, in the case that the sensing mode is the A-transmitting and B-receiving mode, the third device can transmit the sensing signal according to the first sensing resource, or the third device can receive the sensing signal according to the first sensing resource. For yet another example, in the case that the sensing mode is the hybrid sensing mode, the third device can transmit the sensing signal #1 according to the first sensing resource, receive the sensing signal #1, and receive the sensing signal #2 transmitted by other devices (e.g., other RUs).

[0284] 2. The sensing area: details can be referred to the description of the “sensing area” in the first sensing requirement in S901, and will not be repeated here.

[0285] Exemplarily, the third device can receive and / or transmit the sensing signal according to the sensing area indicated by the second information. For example, the third device can receive and / or transmit the sensing signal in the sensing area indicated by the second information. For another example, the third device can transmit the sensing signal to the sensing area indicated by the second information; and / or, the third device can receive the sensing signal from the sensing area indicated by the second information.

[0286] Mode g2: the second device transmits the fourth information; correspondingly, the third device can receive the fourth information. For example, in the scenario 1 in the above, in the case that the second device is the second logical unit and the third device is the third logical unit, the second logical unit can transmit the fourth information to the third logical unit.

[0287] The fourth information can indicate the first sensing resource. The present application does not limit the specific content of the fourth information indicating the first sensing resource.

[0288] Exemplarily, the first sensing resource can include at least one of the following: a time domain resource, a frequency domain resource, a space domain resource, a code domain resource, or a power domain resource.

[0289] In this way, the third device can accurately determine the first sensing resource according to the fourth information.

[0290] Optionally, in mode g2, the fourth information can further indicate at least one of the following: the sensing mode; or, the sensing area. Details can be referred to the description of the second information in mode g1, and will not be repeated here.

[0291] In other possible modes, the first sensing resource can be used for the second device to receive and / or transmit the sensing signal, which can be applicable to the scenario 2 in the above. Optionally, in this mode, the second device can receive and / or transmit the sensing signal according to the first sensing resource.

[0292] Optionally, the second device can receive and / or transmit the sensing signal according to the sensing transceiving mode and / or the sensed area, and details can be referred to the description of the sensing transceiving mode and the sensed area in the manner g1, except that the third device is replaced by the second device, and details are not described herein.

[0293] In some possible manners, the method shown in FIG. 9 can further include steps C1 to C2:

[0294] Step C1: The first device can receive first sensing data. The first sensing data corresponds to the transmission and / or reception of the sensing signal.

[0295] In some implementations, in the above scenario 1, the third device can transmit the first sensing data; correspondingly, the first device can receive the first sensing data. Optionally, the first sensing data can be obtained by the third device according to the received and / or transmitted sensing signal. For example, the first sensing data can be raw data sensed by the third device, or can be data obtained by processing (for example, one or more of dimension alignment, up-sampling, down-sampling) the raw data sensed by the third device, or can be features obtained by processing the raw data sensed by the third device through a neural network, or can be sensing data obtained by performing fusion operation by the third device. The first sensing data can include at least one of the following types of data: I / Q signal, RAV spectrum information or CFR information.

[0296] In some implementations, in the above scenario 2, the second device can transmit the first sensing data; correspondingly, the first device can receive the first sensing data. Optionally, the first sensing data can be obtained by the second device according to the received and / or transmitted sensing signal. For example, the first sensing data can be raw data sensed by the second device, or can be data obtained by processing (for example, one or more of dimension alignment, up-sampling, down-sampling) the raw data sensed by the second device, or can be features obtained by processing the raw data sensed by the second device through a neural network, or can be sensing data obtained by performing fusion operation by the second device. The first sensing data can include at least one of the following types of data: I / Q signal, RAV spectrum information or CFR information.

[0297] Step C2: The first device can transmit second sensing data.

[0298] In some implementations, the first device can transmit the second sensing data to the sensing management network element; correspondingly, the sensing management network element can receive the second sensing data.

[0299] Optionally, in this implementation, in the case where the first device sends the second sensing data to the sensing management network element via the second device and the core network device (e.g., AMF or UPF), the second sensing data and the communication data can be transmitted on different interfaces between the second device and the core network device, or can be transmitted on different logical links on the same interface, or can be contained in different data packets. For example, in scenario 1 above, the second sensing data and the communication data can be transmitted on different interfaces between the CU and the UPF, or can be transmitted on different logical links on the same interface between the CU and the UPF, or can be transmitted in different data packets on the same interface between the CU and the UPF. For another example, in scenario 2 above, the second sensing data and the communication data can be transmitted on different interfaces between the NodeB and the UPF, or can be transmitted on different logical links on the same interface between the NodeB and the UPF, or can be transmitted in different data packets on the same interface between the NodeB and the UPF.

[0300] In some other implementations, the first device can send the second sensing data to the second device. In some examples, in scenario 1 above, in the case where the first device is a first logical unit and the second device is a second logical unit, the first logical unit can send the second sensing data to the second logical unit. In some other examples, in scenario 2 above, in the case where the first device is a first access network device and the second device is a second access network device, the first access network device can send the second sensing data to the second access network device.

[0301] The above implementations can be used independently or in combination. For example, the first device can send the second sensing data to the sensing management network element and the second device.

[0302] In some possible manners, the second sensing data can be the first sensing data; or the first device can transparently transmit the first sensing data.

[0303] In some other possible manners, the second sensing data is obtained by processing the first sensing data; or the first device can process the first sensing data to obtain the second sensing data.

[0304] In some examples, the first device can process the first perception data of the first type to obtain second perception data of a second type. For example, the first perception data is of the type of I / Q signals, and the first device processes the first perception data to obtain the second perception data of the type of CFR information or RAV spectrum information. For another example, the first perception data is of the type of I / Q signals, and the first device processes the first perception data to obtain perception data of the type of CFR information or RAV spectrum information, and processes the perception data of the type of CFR information or RAV spectrum information to obtain the second perception data of the type of point cloud information. For another example, the first perception data is of the type of I / Q signals, and the first device processes the first perception data to obtain perception data of the type of CFR information or RAV spectrum information, processes the perception data of the type of CFR information or RAV spectrum information to obtain perception data of the type of point cloud information, and processes the perception data of the type of point cloud information to obtain the second perception data of the type of perception target information. For another example, the first perception data is of the type of CFR information or RAV spectrum information, and the first device processes the first perception data of the type of CFR information or RAV spectrum information to obtain the second perception data of the type of point cloud information. For another example, the first perception data is of the type of CFR information or RAV spectrum information, and the first device processes the first perception data of the type of CFR information or RAV spectrum information to obtain perception data of the type of point cloud information, and processes the perception data of the type of point cloud information to obtain the second perception data of the type of perception target information.

[0305] In other examples, the first device can perform fusion processing on perception data from multiple devices to obtain the second perception data. The types of the perception data from the multiple devices and the type of the second perception data can be the same or different. The fusion processing is, for example, at least one of fusion processing of I / Q signals from the multiple devices, fusion processing of CFR information from the multiple devices, fusion processing of RAV spectrum information from the multiple devices, and fusion processing of point cloud information from the multiple devices.

[0306] For example, the types of the perception data from the multiple devices received by the first device are of I / Q signals. The first device can perform fusion processing on the perception data from the multiple devices to obtain fused perception data of the type of I / Q signals. The second perception data can be the fused perception data of the type of I / Q signals, or can be a result of processing the fused perception data of the type of I / Q signals, for example, perception data of the type of CFR information or point cloud information.

[0307] For another example, the type of the sensing data received by the first device from the plurality of devices is I / Q signal. The first device can process the sensing data from the plurality of devices to obtain sensing data of the plurality of devices in the type of CFR information, and process the sensing data of the plurality of devices in the type of CFR information to obtain sensing data of the plurality of devices in the type of point cloud information. Then, the first device can fuse the sensing data of the plurality of devices in the type of point cloud information to obtain fused sensing data in the type of point cloud information. The second sensing data can be the fused sensing data in the type of point cloud information, or can be a result of processing the fused sensing data in the type of point cloud information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0308] For another example, the type of the sensing data received by the first device from the plurality of devices is I / Q signal. The first device can process the sensing data from the plurality of devices to obtain sensing data of the plurality of devices in the type of CFR information, and process the sensing data of the plurality of devices in the type of CFR information to obtain sensing data of the plurality of devices in the type of point cloud information. Then, the first device can fuse the sensing data of the plurality of devices in the type of point cloud information to obtain fused sensing data in the type of point cloud information. The second sensing data can be the fused sensing data in the type of point cloud information, or can be a result of processing the fused sensing data in the type of point cloud information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0309] For another example, the type of the sensing data received by the first device from the plurality of devices is CFR information. The first device can fuse the sensing data from the plurality of devices in the type of CFR information to obtain fused sensing data in the type of CFR information. The second sensing data can be the fused sensing data in the type of CFR information, or can be a result of processing the fused sensing data in the type of CFR information, for example, sensing data in the type of point cloud information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0310] For another example, the type of the sensing data received by the first device from the plurality of devices is CFR information. The first device can process the sensing data from the plurality of devices in the type of CFR information to obtain sensing data of the plurality of devices in the type of point cloud information, and fuse the sensing data of the plurality of devices in the type of point cloud information to obtain fused sensing data in the type of point cloud information. The second sensing data can be the fused sensing data in the type of point cloud information, or can be a result of processing the fused sensing data in the type of point cloud information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0311] For example, the type of the perception data received by the first device from the plurality of devices is point cloud information. The first device can perform fusion processing on the perception data from the plurality of devices of the type of point cloud information to obtain fused perception data of the type of point cloud information. The second perception data can be the fused perception data of the type of point cloud information, or can be a result of processing the fused perception data of the type of point cloud information.

[0312] Optionally, in the above example, the plurality of devices are the plurality of second devices, in which case the above example can be applicable to the scenario 2 above; or the plurality of devices are the plurality of third devices, in which case the above example can be applicable to the scenario 1 above.

[0313] For example, the second perception data can include at least one of the following types of data: I / Q signal, RAV spectrum information, CFR information, point cloud information, or perception target information.

[0314] Optionally, the step C1 and the step C2 can be after the S902.

[0315] In this way, the first device at the access network side can process the received first perception data to obtain the second perception data, so that the perception data can be processed without the core network device, improving the processing speed of the perception data and reducing the processing delay of the perception data.

[0316] In some possible manners, the method shown in FIG. 9 can further include a step D1:

[0317] The step D1: The first device receives first indication information.

[0318] In the scenario 1 above, the third device can send the first indication information, and correspondingly, the first device can receive the first indication information. For example, the first device can be a first logical unit, and the third device can be a third logical unit. The first logical unit can receive the first indication information from the third logical unit.

[0319] In the scenario 2 above, the second device can send the first indication information, and correspondingly, the first device can receive the first indication information. For example, the first device can be a first access network device, and the second device can be a second access network device. The first access network device can receive the indication information from the second access network device.

[0320] The first indication information can indicate that the first perception data is for a perception requirement of a perception management network element, or for a perception requirement of the second device. The second device can be a second logical unit in the access network or a device in the second logical unit; or the second device can be a second access network device or a device in the second access network device.

[0321] The first indication information and the first sensing data can be sent together, or the first indication information and the first sensing data can be sent separately. For example, the first indication information and the first sensing data can be carried in the same message or in different messages. The sending sequence of the first indication information and the first sensing data is not limited.

[0322] Optionally, the step D1 can be after the S902.

[0323] In this way, the first device can accurately determine, according to the first indication information, whether the first sensing data is for the sensing requirement of the sensing management network element or for the sensing requirement of the second device.

[0324] Correspondingly, the step C2 can include: in the case that the first sensing data is for the sensing requirement of the sensing management network element, the first device sends the second sensing data to the sensing management network element; and / or in the case that the first sensing data is for the sensing requirement of the second device, the first device sends the second sensing data to the second device.

[0325] In this way, the first device can send the sensing data to the sensing requirement party according to the first indication information, thereby reducing the overhead and saving the transmission resource.

[0326] The methods shown in FIGS. 10-14 are possible examples of the method shown in FIG. 9. In the methods shown in FIGS. 10-12, the first device is taken as an SU, the second device is taken as a CU, and the third device is taken as an RU. In the methods shown in FIGS. 13-14, the first device is taken as a NodeC, and the second device is taken as a NodeB.

[0336] Optionally, before sending the second information, the SU can select a node for sensing, for example, can select the CU and / or the RU. For example, the SU can select the CU and / or the DU that support sensing, and the selection is based on the capability of the CU and / or the RU. For example, the CU can send information indicating the capability of the CU to the SU, and in the case that the information indicating the capability of the CU indicates that the CU supports sensing, the SU can select the CU. For example, the CU can send information indicating the capability of the CU and information indicating the capability of the RU managed by the CU to the SU, and in the case that the information indicating the capability of the CU indicates that the CU supports sensing and the information indicating the capability of the RU managed by the CU indicates that the RU managed by the CU supports sensing, the SU can select the CU and the RU. For example, the CU can send information indicating the capability of the RU managed by the CU to the SU, and in the case that the information indicating the capability of the RU managed by the CU indicates that the RU managed by the CU supports sensing, the SU can select the CU and the RU. For example, the RU can send information indicating the capability of the RU to the SU, and in the case that the information indicating the capability of the RU indicates that the RU supports sensing, the SU can select the RU.

[0365] The specific content of S1009 can refer to the description of "the first device can process the first perception data to obtain the second perception data" in step C2 of the method shown in FIG. 9, and will not be repeated here.

[0366] Through the method shown in FIG. 10, the SU on the access network side can make a decision on the perception resource. Since the device on the access network side can conveniently obtain the condition of the resource on the access network side, the device can determine the perception resource that is suitable for the condition on the access network side, and thus can meet the perception requirement, better guarantee the QoS or SLA of the perception service, improve the perception performance, and improve the efficiency of the perception management.

[0367] And, in the method, the SU can be used for sensing, the SU is independent of the CU and / or the RU used for communication, so that the scalability of the SU can be improved, and in turn, higher sensing requirements can be met by upgrading the SU, and better support for evolution of future sensing functions can be provided.
