[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202410896337.9, 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 needs 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, a terminal can provide sensing data. How to process the sensing data of the terminal still needs further research. SUMMARY

[0006] The present application provides a communication method and apparatus for processing the sensing data of a terminal.

[0007] In a first aspect, an embodiment of the present application provides a communication method, which can be applied to a first apparatus at an access network side. The first apparatus can be a first logical unit in the access network or an apparatus (e.g., a module, a communication module, a circuit, a chip (such as a modem chip, also known as 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 apparatus can be a first access network device or an apparatus (e.g., 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 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.

[0008] The method includes: receiving, by the first apparatus, sensing data of at least one terminal; and processing the sensing data of the at least one terminal according to whether the position of the at least one terminal is obtained.

[0009] In the method, the first device can process the perception data of the at least one terminal according to whether the position of the at least one terminal is acquired. In one case, the first device can acquire the position of the at least one terminal, and thus can process the perception data of the at least one terminal according to the position of the at least one terminal. In this case, the position of the at least one terminal can be a reference position of the at least one terminal, instead of an actual position of the at least one terminal. Since the position of the terminal is the privacy of the terminal, the method can improve the performance of the perception processing while ensuring the privacy of the terminal.

[0010] In addition, in the method, the first device can be used for perception, and the device used for communication by the access network side is independent of the first device, so that the scalability of the first device can be improved, and thus the first device can be upgraded to meet higher perception requirements.

[0011] In one possible design, in the case where the position of the at least one terminal is acquired, the first device processes the perception data of the at least one terminal according to the position of the at least one terminal. With this design, the access network side can process the perception data of the terminal. Compared with processing the perception data of the terminal by a core network device or a third-party server, this design can reduce the processing delay of the perception data of the terminal. In addition, in this design, the position of the at least one terminal acquired by the first device can be a reference position of the at least one terminal, instead of an actual position of the at least one terminal. The actual position of the terminal belongs to the privacy of the terminal. Therefore, with this design, the processing delay of the perception data of the terminal can be reduced, and the performance of the perception processing can be improved while ensuring the privacy of the at least one terminal.

[0012] And / or, in the case where the position of the at least one terminal is not acquired, the first device sends the perception data of the at least one terminal, and receives first perception data, which is obtained by processing the perception data of the at least one terminal according to the position of the at least one terminal. With this design, the first device of the access network side can acquire the first perception data, which is obtained by processing the perception data of the at least one terminal according to the position of the at least one terminal. In this design, the access network side can not acquire the position of the at least one terminal. The actual position of the terminal belongs to the privacy of the terminal. Therefore, this method can process the perception data of the at least one terminal while ensuring the privacy of the at least one terminal.

[0013] In a possible design, the first device can further receive first indication information, where the first indication information indicates whether there is terminal participation in sensing. With this design, the first device can accurately determine whether there is terminal participation in sensing according to the first indication information. In this design, whether there is terminal participation in sensing is indicated by the first indication information, and the first device can not calculate whether there is terminal participation in sensing, thereby reducing the calculation complexity of the first device and reducing the power consumption of the first device.

[0014] In a possible design, in a case where the first indication information indicates that there is terminal participation in sensing, the first device sends a first request, where the first request is used to request the position of the at least one terminal. With this design, the first device can request the position of the at least one terminal on demand, avoiding unnecessary transmission of information indicating the position of the at least one terminal, thereby saving transmission resources.

[0015] In a possible design, in a case where the first indication information indicates that there is terminal participation in sensing and the position of the at least one terminal is not acquired, the first device sends a second request, where the second request is used to request first sensing data, and the first sensing data is obtained by processing sensing data of the at least one terminal according to the position of the at least one terminal. With this design, the first device can request the first sensing data on demand, avoiding unnecessary transmission of the first sensing data, thereby saving transmission resources.

[0016] In a possible design, the first device further acquires second sensing data. In a case where the position of the at least one terminal is acquired, the second sensing data is obtained by fusing the sensing data of the at least one terminal and third sensing data obtained by access network side sensing; and / or in a case where the position of the at least one terminal is not acquired, the second sensing data is obtained by fusing the first sensing data and the third sensing data obtained by access network side sensing, where the first sensing data is obtained by processing the sensing data of the at least one terminal according to the position of the at least one terminal. In this design, the first device can obtain the second sensing data according to sensing data from multiple devices, thereby performing sensing processing according to more comprehensive sensing data and improving sensing performance.

[0017] In a possible design, the sensing data of the at least one terminal and the third sensing data are transmitted on different interfaces, or transmitted on different logical links on the same interface, or contained in different data packets. With this design, each device can accurately determine whether the received sensing data is the sensing data of the at least one terminal or the third sensing data obtained by access network side sensing.

[0018] In one possible design, the first apparatus further transmits second awareness data, which corresponds to the awareness data of the at least one terminal. For example, the first apparatus can transmit the second awareness data to the awareness management network element, which can accurately obtain the second awareness data, and thus can perform more effective awareness management based on the second awareness data. For another example, the first apparatus can transmit the second awareness data to the second apparatus, which can perform communication based on the second awareness data, or the second awareness data can be used to assist communication.

[0019] In one possible design, the first apparatus further receives first information, which indicates a first awareness requirement. The first apparatus transmits second information, which is used to determine a first awareness resource. The first awareness resource is used by the at least one terminal to transmit and / or receive an awareness signal, which corresponds to a second awareness requirement determined based on the first awareness requirement.

[0020] With this design, the first apparatus at the access network side can transmit the second information used to determine the first awareness resource after receiving the first information indicating the first awareness requirement. In this way, the first awareness resource can be determined at the access network side. Since the apparatus at the access network side can conveniently obtain the condition of the resources at the access network side, the apparatus can determine an awareness resource that is suitable for the condition at the access network side, and thus can satisfy the awareness requirement, improve awareness performance, and improve the efficiency of awareness management.

[0021] In addition, since the apparatus at the access network side can quickly obtain the condition of the resources at the access network side, the apparatus can reduce the latency of determining the awareness resource, and thus can improve awareness performance and improve the efficiency of awareness management.

[0022] In one possible design, the second information indicates the first awareness resource. With this design, the first apparatus can accurately indicate the first awareness resource through the second information. In this approach, the awareness resource can be determined by the first apparatus at the access network side, and thus the first apparatus can have improved flexibility in awareness management, and thus the efficiency of awareness management can be improved. Alternatively, the second information indicates a second awareness requirement, which is used to determine the first awareness resource. In this way, the second apparatus can determine the first awareness resource that matches the second awareness requirement based on the second awareness requirement indicated by the second information. In this approach, the awareness resource can be determined by the second apparatus, and thus the second apparatus can have improved flexibility in awareness management, and thus the efficiency of awareness management can be improved.

[0023] In one possible design, the first apparatus further receives third information in the case where the second information indicates the first sensing resource, where the third information indicates recommended and / or non-recommended sensing resources, and where the third information is used to determine the first sensing resource. With this design, the first apparatus can learn the recommended and / or non-recommended sensing resources, and thus can select appropriate sensing resources accordingly, which can better satisfy the sensing requirement and improve the efficiency of sensing management.

[0024] In one possible design, the first apparatus further receives first response information in the case where the second information indicates the first sensing resource, where the first response information indicates acceptance or rejection of the first sensing resource for implementing the second sensing requirement. In this way, the first apparatus can accurately determine whether the second apparatus accepts or rejects the first sensing resource for implementing the second sensing requirement based on the first response information.

[0025] In one possible design, the first response information further indicates at least one of the following in the case where the first response information indicates rejection of the first sensing resource for implementing the second sensing requirement: a rejection reason; or, recommended and / or non-recommended sensing resources. In this way, the first apparatus can learn the rejection reason of the first sensing resource for implementing the second sensing requirement and / or the recommended and / or non-recommended sensing resources, and thus can adjust the second information accordingly, e.g., can adjust the sensing requirement for the second apparatus and / or the sensing resources configured for the at least one terminal, such that the adjusted second information (or the sensing resources determined based on the adjusted second information) is adapted to the resource situation at the terminal side, which can satisfy the sensing requirement, improve the sensing performance, and improve the efficiency of sensing management.

[0026] In one possible design, the second information further indicates at least one of the following in the case where the second information indicates the first sensing resource: a transceiving mode for sensing by the at least one terminal; or, a sensing region for sensing by the at least one terminal. With this design, the second apparatus can accurately determine the transceiving mode for sensing and / or the sensing region based on the second information, which can improve the sensing performance. In this design, the transceiving mode for sensing and / or the sensing region can be indicated by the first apparatus, which can improve the flexibility of sensing management by the first apparatus.

[0027] In one possible design, the first apparatus receives second response information in the case where the second information indicates the second sensing requirement. In this case, the second response information indicates the first sensing resource, which can enable the first apparatus to accurately determine the first sensing resource based on the second response information; or the second response information indicates rejection of the second sensing requirement, which can enable the first apparatus to accurately determine that the second apparatus rejects the second sensing requirement based on the second response information.

[0028] In a possible design, in a case where the second response information indicates the first sensing resource, the second response information further indicates at least one of: a transceiving mode in which the at least one terminal performs sensing; or, a region in which the at least one terminal performs sensing. With this design, the second response information can accurately indicate the transceiving mode in which sensing is performed and / or the region in which sensing is performed, thereby improving the efficiency of sensing management and improving sensing performance.

[0029] In a possible design, in a case where the second response information indicates that the second sensing requirement is rejected, the second response information further indicates at least one of: a rejection reason; recommended and / or non-recommended sensing resource; or, implementable sensing requirement. In this way, the first apparatus can learn one or more of the rejection reason for rejecting the second sensing requirement, the recommended and / or non-recommended sensing resource, or the implementable sensing requirement, and can adjust the sensing requirement for the second apparatus accordingly, so that the adjusted sensing requirement is adapted to the resource situation on the terminal side served by the second apparatus, thereby meeting the sensing requirement, improving sensing performance, and improving the efficiency of sensing management.

[0030] In a possible design, the rejection reason includes at least one of: insufficient time-domain resource; insufficient frequency-domain resource; insufficient spatial-domain resource; insufficient code-domain resource; insufficient power-domain resource; no terminal available for sensing; or, the terminal does not meet the second sensing requirement. This design provides multiple forms of rejection reason, which is more flexible and easy to implement.

[0031] In a possible design, the first apparatus receives the first information from a sensing management network element; or, the first apparatus receives the first information from the second logical unit or the second access network device. This design provides multiple ways of obtaining the first information used to indicate the first sensing requirement, which is more flexible. In addition, in a case where the first apparatus can receive the first information from the second logical unit or the second access network device, the first apparatus can obtain the first sensing requirement from the second logical unit or the second access network device on the access network side, thereby improving the efficiency of access network management of sensing and reducing the time delay of obtaining the first sensing requirement.

[0032] In a possible design, the first sensing requirement includes at least one of the following information: sensing quality of service (QoS) or service level agreement (SLA); type of sensing data; time of sensing; or, region of sensing. This design provides multiple possible ways of sensing requirement, thereby enabling flexible configuration of the sensing requirement.

[0033] In one possible design, the type of the perception data includes at least one of: in-phase / quadrature (I / Q) signals, range-angle-velocity (RAV) spectrum information, channel frequency response (CFR) information, point cloud information, or perception target information. This design provides multiple possible ways for the type of the perception data, and thus the type of the perception data can be flexibly configured.

[0078] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. 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.

[0079] The present application will present various aspects, embodiments or features around a system that can include a plurality of devices, components, modules, etc. It should be understood and appreciated that each system can include additional devices, components, modules, etc., and / or can not include all of the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. In addition, combinations of these solutions can also be used.

[0080] In order to facilitate understanding of the embodiments of the present application, FIG. 1A shows a possible, non-limiting system schematic diagram. As shown in FIG. 1A, the communication system 10 includes a radio access network (radio access network, RAN) 100 and a core network (core network, CN) 200. Optionally, the communication system 10 can also include the Internet 300.

[0081] 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 wirelessly connected to the RAN nodes 110. The RAN nodes 110 are connected to a core network 200 through wireless or wired means. 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 wireless access network.

[0082] 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.

[0083] The RAN nodes 110, which can also be referred to as RAN entities or access nodes, etc., form part of the communication system and help terminals to access wirelessly. 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 nodes 110 and the terminals 120 are relative, e.g., the network element 120i in FIG. 1A can be a helicopter or a drone, which can be configured as a mobile base station. For a terminal 120j that accesses the RAN 100 through the network element 120i, the network element 120i is a base station; but for 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 apparatuses, e.g., the network elements 110a and 110b in FIG. 1A can be understood as communication apparatuses with base station functions, and the network elements 120a-120j can be understood as communication apparatuses with terminal functions.

[0084] The RAN nodes can also be referred to as access network devices. In the following, the RAN nodes are referred to as access network devices unless otherwise specified.

[0085] 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 base station 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 (such as 110a in FIG. 1A), a micro base station or an indoor station (such as 110b in FIG. 1A), a relay node or a donor node, or a wireless controller in a CRAN scenario, a satellite, a drone, a balloon, an airplane, etc. Alternatively, 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). All or part of the functions of the access network device in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The access network device in this application can also be a logical node, a logical module or software capable of implementing all or part of the functions of the access network device.

[0086] 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 the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as 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.

[0087] In different systems, the CU (or the CU-CP and the CU-UP), the DU, or the RU can also have different names, but those 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] Table 1

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] The present application can be applicable to scenario 1 and / or scenario 2.

[0098] 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).

[0099] Exemplarily, 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.

[0100] Optionally, in the scenario 1, the interaction between the first device and the sensing management network element can be in various manners, for example, at least one of the manner a1 to the manner a8. 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, sensing data) between the first device and the sensing management network element can be the same or different. The following takes the first device as the SU for example to illustrate.

[0101] The manner a1: the sensing management network element is an independent network element (for example, the SF) in the core network.

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 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.

[0132] Option d8: the awareness management network element can be an awareness function device integrated in a core network device. (h) 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 (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.

[0133] 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.

[0134] Optionally, in the case that the Node C and the awareness management network element interact through the way d2, the way d5 or the way 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 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 UPF include one interface, and the data packets transmitted on the interface can contain or be associated with information 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 awareness data and communication data.

[0135] Optionally, in this scenario 2, the interaction between the second device and the awareness management network element can be in various ways, for example, at least one of the ways e1 to e5. Among them, the interaction of the control plane information and the interaction of the user plane (or called data plane) information (such as awareness data) between the second device and the awareness management network element can be the same or different.

[0136] Way e1: the awareness management network element is an independent network element (for example, SF) in the core network. For example, the awareness management network element is SF, which is illustrated in (a) of FIG. 6. As shown in (a) of FIG. 6, the second device (for example, Node B is illustrated in (a) of 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. Optionally, in this way, the interaction of the control plane information and the user plane information between the second device and the SF can be the same.

[0137] Way e2: the awareness management network element is an independent network element (for example, SF) in the core network. For example, the awareness management network element is SF, which is illustrated in (b) of FIG. 6. As shown in (b) of FIG. 6, the second device (for example, Node B is illustrated in (b) of FIG. 6) can interact with the SF through the core network equipment (for example, AMF and / or UPF is illustrated in (b) of 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.

[0138] Way e3: the awareness management network element is a third-party server (referred to as an awareness server in (c) 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.

[0141] 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.

[0142] 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.

[0143] 1. Communication and perception integration:

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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 static 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.

[0149] 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.

[0150] 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.

[0151] The frequency unit can be an absolute frequency or can be a unit of a frequency domain resource. Exemplarily, the frequency unit can include at least one of a subcarrier, a resource element (RE), a resource block (RB), a resource block group (RBG), and the like.

[0152] 3、In this application, the perception data of a certain device can be the original data perceived by the device, or can be the data after the device processes the original perceived data (for example, one or more of dimension alignment, upsampling, downsampling), or can be the features obtained after the original perceived data is processed by a neural network, or can be the perception data obtained by the device after fusion operation.

[0153] 4、In this 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 used to indicate 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.

[0154] The indication manner involved in the embodiments of this 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.

[0155] The "information" in the embodiments of this application can be explicitly indicated, that is, 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. It can also be implicitly indicated, that is, obtained according to rules or relationships, or according to other parameters, or through derivation. It is not limited.

[0156] 5、In this 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. the need for other devices to transfer or forward), or can mean that the functional units inside the device communicate with other devices through another functional unit. For example, "sending information to (terminal)" can be understood as the destination of the information is the terminal, which can include direct or indirect sending information to the terminal. "Receiving information from (terminal)" can be understood as the source of the information is the terminal, which can include direct or indirect receiving information from the terminal. The information between the source and the destination of the information sending may be processed as necessary, such as format change, digital to analog conversion, amplification, filtering and other processing, but the destination can understand the effective information from the source. Similar expressions in this application can be similarly understood, and will not be repeated here.

[0157] 6、In this application, the words "exemplarily", "such as", "for example" and "an example of" are used to represent examples, illustrations or descriptions, and are not used to limit the protection scope of the application. It should be understood that the examples in this application can also be implemented in other ways.

[0158] 7、In this application, any two of the program, instruction and code can be replaced with each other.

[0159] 8、In this application, the processing of perception data can include but not limited to at least one of the following: fusion processing, or perception data calculation.

[0160] Currently, in the ISAC system, the terminal participates in perception, which can improve the perception performance. For example, if the terminal sends and / or receives the perception signal, the range of perception can be expanded. Also for example, the terminal can provide perception data. If the perception data of the terminal is fused, for example, the perception data of the terminal and the perception data of the access network side are fused, or the perception data of multiple terminals are fused, the perception accuracy can be improved, so as to better guarantee the perception QoS or SLA.

[0161] In the case of terminal participating in perception, how to process the perception data of the terminal also needs further research.

[0162] Embodiments of the present application provide a communication method. Figure 9 is a flowchart of the communication method provided by the embodiments of the present application.

[0163] The method is schematically shown in FIG. 9 with the perception management network element, the first device on the access network side, and the second device on the access network side as the execution subject of the interaction, but the application does not limit the execution subject of the interaction. For example, the perception 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 perception management network element, or can be replaced by a logical node, a logical module, or software that can implement all or part of the functions of the perception management network element.

[0164] In some examples, the perception management network element can be a core network device. For example, the perception management network element is a standalone network element (such as an SF) in the core network. The SF can also have other names, such as a perception management function, as long as it has the same function and is within the protection scope of the application. For another example, the perception management network element can be integrated with the core network device in one device, such as the perception management network element can be a perception function device integrated in the core network device, or the perception management network element and the core network device can be different devices in one device. The core network device is, for example, an AMF and / or a UPF. In other examples, the perception 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 perception management network element can have other names, such as a perception network element, a perception server, or a perception network element / server, as long as it has the same function and is within the protection scope of the application.

[0165] As shown in FIG. 9, the method includes:

[0166] S901: At least one terminal sends perception data of the at least one terminal; correspondingly, the first device receives the perception data of the at least one terminal.

[0167] The first terminal can be any terminal in the at least one terminal. The following takes the first terminal as an example to illustrate S901.

[0168] In some possible manners, in the above scenario 1, the first terminal can send the perception data of the first terminal to the first device through the third device and the second device in sequence. For example, the third device is an RU, the second device includes a CU and a DU, and the first device is an SU. The first terminal can send the perception data of the first terminal to the SU through the RU, the DU, and the CU in sequence. For another example, the third device is an RU, the second device includes a CU, and the first device is an SU. The first terminal can send the perception data of the first terminal to the SU through the RU and the CU in sequence. For another example, the third device is an RU, the second device includes a DU, and the first device is an SU. The first terminal can send the perception data of the first terminal to the SU through the RU and the DU in sequence.

[0169] In some other possible manners, in scenario 1 above, the first terminal can send the sensing data of the first terminal to the first device via a third device. For example, the third device is a RU, and the first device is a SU. The first terminal can send the sensing data of the first terminal to the SU via the RU.

[0170] In some other possible manners, in scenario 2 above, the first terminal can send the sensing data of the first terminal to the first device via a second device. For example, the second device is a NodeB, and the first device is a NodeC. The first terminal can send the sensing data of the first terminal to the NodeC via the NodeB.

[0171] It should be understood that the time when different terminals of the at least one terminal send the sensing data can be the same or different.

[0172] For example, the type of the sensing data of the at least one terminal can include at least one of the following: I / Q signal, CFR information, RAV spectrum information, or point cloud information. It should be understood that the type of the sensing data of different terminals of the at least one terminal can be the same or different.

[0173] S902: The first device can process the sensing data of the at least one terminal according to whether the position of the at least one terminal is acquired.

[0174] In some examples, the position of the at least one terminal can be the actual position of the at least one terminal.

[0175] In some other examples, the position of the at least one terminal can be a reference position of the at least one terminal. The reference position of the at least one terminal is different from the actual position of the at least one terminal, and corresponds to (or is related to or associated with) the actual position of the at least one terminal. For example, the distance between the reference position of the at least one terminal and the actual position of the at least one terminal is a first offset value, or the distance between the reference position of the at least one terminal and the actual position of the at least one terminal is less than (or less than or equal to) the first offset value. The first offset value can be pre-set, for example, specified by a protocol, or determined by the first device, or notified to the first device by another device (for example, a core network device). The reference position and / or the first offset value can also have other names as long as they have the same function and are within the protection scope of the present application.

[0176] S902 can have various implementation manners, for example, manner f1 and / or manner f2.

[0177] Manner f1: In the case where the position of the at least one terminal is acquired, the first device can process the sensing data of the at least one terminal according to the position of the at least one terminal.

[0178] In some implementations, the first device can fuse the perception data of the at least one terminal according to the locations of the at least one terminal. The fusion processing is, for example, at least one of: I / Q signal fusion processing, CFR information fusion processing, RAV spectrum information fusion processing, or point cloud information fusion processing.

[0179] For example (hereinafter referred to as Example One), the type of the perception data of the at least one terminal received by the first device is I / Q signal. The first device can fuse the perception data of the at least one terminal according to the locations of the at least one terminal to obtain fused perception data of the at least one terminal of the type of I / Q signal.

[0180] For example (hereinafter referred to as Example Two), the type of the perception data of the at least one terminal received by the first device is I / Q signal. The first device can process the perception data of the at least one terminal to obtain perception data of the at least one terminal of the type of CFR information. Then, the first device can fuse the perception data of the at least one terminal of the type of CFR information according to the locations of the at least one terminal to obtain fused perception data of the at least one terminal of the type of CFR information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0181] For example, the type of the perception data of the at least one terminal received by the first device is I / Q signal. The first device can process the perception data of the at least one terminal to obtain perception data of the at least one terminal of the type of CFR information, and process the perception data of the at least one terminal of the type of CFR information to obtain perception data of the at least one terminal of the type of point cloud information. Then, the first device can fuse the perception data of the at least one terminal of the type of point cloud information according to the locations of the at least one terminal to obtain fused perception data of the at least one terminal of the type of point cloud information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0182] For example, the type of the perception data of the at least one terminal received by the first device is CFR information. The first device can fuse the perception data of the at least one terminal according to the locations of the at least one terminal to obtain fused perception data of the at least one terminal of the type of CFR information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0183] For another example, the type of the perception data of the at least one terminal received by the first device is CFR information. The first device can process the perception data of the at least one terminal of the type of CFR information to obtain perception data of the at least one terminal of the type of point cloud information, and then perform fusion processing on the perception data of the at least one terminal of the type of point cloud information according to the positions of the at least one terminal to obtain fused perception data of the type of point cloud information. Optionally, the CFR information in this example can be replaced by RAV spectrum information.

[0184] For another example, the type of the perception data of the at least one terminal received by the first device is point cloud information. The first device can perform fusion processing on the perception data of the at least one terminal of the type of point cloud information according to the positions of the at least one terminal to obtain fused perception data of the type of point cloud information.

[0185] It should be understood that the implementation is described by taking fusion processing on the perception data of the at least one terminal as an example. In actual application, the first device can also perform other processing on the perception data of the at least one terminal in addition to fusion processing, which is not limited.

[0186] In other implementations, the first device can perform fusion processing on the perception data of the at least one terminal and third perception data sensed by the access network side according to the positions of the at least one terminal, and the specific content can refer to the description of “the first device can perform fusion processing on the perception data of the at least one terminal” above, except that “the perception data of the at least one terminal” is replaced by “the perception data of the at least one terminal and the third perception data sensed by the access network side”, which is not described herein again.

[0187] In some examples, in scenario 1 above, the third perception data sensed by the access network side can be third perception data sensed by a third device. The third device can send the third perception data, and accordingly, the first device can receive the third perception data from the third device, so as to fuse the perception data of the at least one terminal and the third perception data.

[0188] In other examples, in scenario 2 above, the third perception data sensed by the access network side can be third perception data sensed by a second device. The second device can send the third perception data, and accordingly, the first device can receive the third perception data from the second device, so as to fuse the perception data of the at least one terminal and the third perception data.

[0189] Optionally, the types of the perception data of the at least one terminal and the third perception data received by the first device can be the same or different.

[0190] In some examples, in a case that the first type of the perception data of the at least one terminal and the third perception data received by the first device are of a same type, the first device can directly fuse the perception data of the at least one terminal and the third perception data according to the location of the at least one terminal, or the first device can process the first type of the perception data of the at least one terminal and the third perception data into a second type of perception data, and fuse the second type of the perception data of the at least one terminal and the third perception data, the first type and the second type can be different. For example (hereinafter referred to as example three), the first type of the perception data of the at least one terminal and the third perception data received by the first device are both I / Q signals. The first device can directly fuse the perception data of the at least one terminal and the third perception data of the at least one terminal according to the location of the at least one terminal, to obtain fused perception data of the at least one terminal of the type of I / Q signals. For another example (hereinafter referred to as example four), the first type of the perception data of the at least one terminal and the third perception data received by the first device are both I / Q signals. The first device can process the perception data of the at least one terminal of the type of I / Q signals, to obtain perception data of the at least one terminal of the type of CFR information, and process the third perception data of the type of I / Q signals, to obtain third perception data of the type of CFR information. Then, the first device can fuse the perception data of the at least one terminal of the type of CFR information and the third perception data of the type of CFR information according to the location of the at least one terminal, to obtain fused fusion data of the type of CFR information.

[0191] In some examples, the first device can process the perception data of the at least one terminal and / or the third perception data, so that the type of the perception data of the at least one terminal and the type of the third perception data are the same, in the case that the type of the perception data of the at least one terminal received by the first device and the type of the third perception data are different. Then, the first device can perform fusion processing on the perception data of the at least one terminal and the third perception data according to the location of the at least one terminal. For example, the type of the perception data of the at least one terminal received by the first device is I / Q signal, and the type of the third perception data received by the first device is CFR information. The first device can process the perception data of the at least one terminal of the type of I / Q signal to obtain the perception data of the at least one terminal of the type of CFR information. Then, the first device can perform fusion processing on the perception data of the at least one terminal of the type of CFR information and the third perception data of the type of CFR information according to the location of the at least one terminal to obtain the fused fusion data of the type of CFR information. For another example (hereinafter referred to as Example Five), the type of the perception data of the at least one terminal received by the first device is I / Q signal, and the type of the third perception data received by the first device is CFR information. The first device can process the perception data of the at least one terminal of the type of I / Q signal to obtain the perception data of the at least one terminal of the type of point cloud information, and process the third perception data of the type of CFR information to obtain the third perception data of the type of point cloud information. Then, the first device can perform fusion processing on the perception data of the at least one terminal of the type of point cloud information and the third perception data of the type of point cloud information according to the location of the at least one terminal to obtain the fused fusion data of the type of point cloud information. For another example, the type of the perception data of the at least one terminal received by the first device is CFR information, and the type of the third perception data received by the first device is I / Q signal. The first device can process the third perception data of the type of I / Q signal to obtain the third perception data of the type of CFR information. Then, the first device can perform fusion processing on the perception data of the at least one terminal of the type of CFR information and the third perception data of the type of CFR information according to the location of the at least one terminal to obtain the fused fusion data of the type of CFR information.

[0192] It should be understood that the implementation is described by taking fusion processing on the perception data of the at least one terminal and the third perception data as an example. In actual application, the first device can also perform other processing on the perception data of the at least one terminal and the third perception data according to the location of the at least one terminal, without limitation.

[0193] In the manner f1, the first device at the access network side can process the perception data of the at least one terminal according to the position of the at least one terminal, so that the processing of the perception data of the terminal at the access network side can be realized. Compared with the processing of the perception data of the terminal by the core network device or the third party server, the processing delay of the perception data of the terminal can be reduced.

[0194] In addition, in the manner, the position of the at least one terminal acquired by the first device can be the reference position of the at least one terminal, instead of the actual position of the at least one terminal. The actual position of the terminal belongs to the privacy of the terminal. Therefore, by the manner, the processing delay of the perception data of the terminal can be reduced and the performance of the perception processing can be improved while ensuring the privacy of the at least one terminal.

[0195] The manner f2 can include steps A1 to A2.

[0196] The manner f2 can include steps A1 to A2.

[0197] In step A1, when the position of the at least one terminal is not acquired, the first device can send the perception data of the at least one terminal; correspondingly, the perception management network element can receive the perception data of the at least one terminal.

[0198] In some implementations, in the scenario 1 above, the first device can send the perception data of the at least one terminal to the perception management network element by at least one of the manners a1 to a8.

[0199] In some implementations, in the scenario 2 above, the first device can send the perception data of the at least one terminal to the perception management network element by at least one of the manners d1 to d8.

[0200] Optionally, in step A1, the first device can further send information indicating the type of the perception data of the at least one terminal to the perception management network element. In this way, the perception management network element can accurately determine the type of the perception data of the at least one terminal.

[0201] For example, in this step A1, the type of the perception data of the at least one terminal can include at least one of the following: RAV spectrum information or point cloud information.

[0202] In step A2, the perception management network element can send the first perception data; correspondingly, the first device can receive the first perception data.

[0203] In some implementations, in the scenario 1 above, the perception management network element can send the first perception data to the first device by at least one of the manners a1 to a8.

[0204] In some other implementations, in scenario 2 above, the perception management network element can send the first perception data to the first device through at least one of the following manners d1-d8.

[0205] The first perception data is obtained by processing the perception data of the at least one terminal according to the location of the at least one terminal. Optionally, the first perception data can be obtained by the perception management network element processing the perception data of the at least one terminal according to the location of the at least one terminal; or the perception management network element can process the perception data of the at least one terminal according to the location of the at least one terminal to obtain the first perception data. For details, refer to the description of "the first device can process the perception data of the at least one terminal according to the location of the at least one terminal" in manner f1, except that the first device is replaced by the perception management network element, which will not be repeated here.

[0206] Optionally, in step A2, the perception management network element can also send information indicating the type of the first perception data to the first device. In this way, the first device can accurately determine the type of the first perception data.

[0207] For example, in this step A2, the type of the first perception data can include at least one of the following: RAV spectrum information or point cloud information.

[0208] In manner f2, the first device on the access network side can obtain the first perception data, which is obtained by processing the perception data of the at least one terminal according to the location of the at least one terminal. In this manner, the access network side can not obtain the location of the at least one terminal. The actual location of the terminal belongs to the privacy of the terminal. Therefore, this manner can realize the processing of the perception data of the at least one terminal while ensuring the privacy of the at least one terminal.

[0209] Optionally, in manner f2, the method shown in FIG. 9 can further include step A3:

[0210] Step A3: The first device processes the first perception data.

[0211] In some implementations, the first device can process the first perception data of the first type to obtain perception data of a second type. For example (hereinafter referred to as Example Six), the first type of the first perception data received by the first device is an I / Q signal. The first device processes the first perception data to obtain perception data of a type of CFR information or RAV spectrum information. For another example (hereinafter referred to as Example Seven), the first type of the first perception data received by the first device is an I / Q signal. The first device processes the first perception data to obtain perception data of a 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 perception data of a type of point cloud information. For yet another example, the first type of the first perception data received by the first device is an I / Q signal. The first device processes the first perception data to obtain perception data of a 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 a type of point cloud information, and processes the perception data of the type of point cloud information to obtain perception data of a type of perception target information. For yet another example, the first type of the first perception data received by the first device is a type of CFR information or RAV spectrum information. The first device processes the first perception data of the type of CFR information or RAV spectrum information to obtain perception data of a type of point cloud information. For yet another example, the first type of the first perception data received by the first device is a type of CFR information or RAV spectrum information. The first device processes the first perception data of the type of CFR information or RAV spectrum information to obtain perception data of a type of point cloud information, and processes the perception data of the type of point cloud information to obtain perception data of a type of perception target information.

[0212] In some other examples, the first device can perform fusion processing on the first perception data and third perception data of access network side sensing. Details can be referred to the description of the “the first device can perform fusion processing on the perception data of at least one terminal and third perception data of access network side sensing according to the position of the at least one terminal” in the manner f1 above, except that the perception data of at least one terminal is replaced by the first perception data, and the “according to the position of the at least one terminal” is deleted, and details are not repeated here.

[0213] In some possible manners, the method shown in FIG. 9 can further include S903:

[0214] S903: The first device receives first indication information, and the first indication information indicates whether there is a terminal participating in perception.

[0215] In some implementations, the first apparatus can receive the first indication information from the perception management network element, as shown in S903a. Optionally, the first indication information is determined by the perception management network element according to a first perception requirement (e.g., the first perception requirement in S906 or S908 below). The details of the first perception requirement will be described below in S906, which will not be elaborated here. For example, in a case where the area of perception in the first perception requirement includes the area where the terminal is located, the perception management network element can determine that the first indication information indicates that the terminal participates in the perception; and / or in a case where the area of perception in the first perception requirement does not include the area where the terminal is located, the perception management network element can determine that the first indication information indicates that the terminal does not participate in the perception.

[0216] In some implementations, the first apparatus can receive the first indication information from the perception management network element, as shown in S903a. Optionally, the first indication information is determined by the perception management network element according to a first perception requirement (e.g., the first perception requirement in S906 or S908 below). The details of the first perception requirement will be described below in S906, which will not be elaborated here. For example, in a case where the area of perception in the first perception requirement includes the area where the terminal is located, the perception management network element can determine that the first indication information indicates that the terminal participates in the perception; and / or in a case where the area of perception in the first perception requirement does not include the area where the terminal is located, the perception management network element can determine that the first indication information indicates that the terminal does not participate in the perception.

[0217] Optionally, S903 can be performed before S902, and the execution order of S903 and S901 is not limited in the present application.

[0218] In this way, the first apparatus can accurately determine whether the terminal participates in the perception according to the first indication information. In this way, whether the terminal participates in the perception is indicated by the first indication information, and the first apparatus can not calculate whether the terminal participates in the perception, thereby reducing the calculation complexity of the first apparatus and reducing the power consumption of the first apparatus.

[0219] In some other possible manners, the first apparatus can determine whether there is terminal participating in the sensing by itself. Alternatively, the first apparatus can determine whether there is terminal participating in the sensing according to a sensing requirement (e.g., the first sensing requirement in S906). The first sensing requirement can be informed to the first apparatus by the sensing management network element or the second apparatus. For example, in a case that the sensing area in the first sensing requirement includes the area where the terminal is located, the first apparatus can determine that there is terminal participating in the sensing; and / or in a case that the sensing area in the first sensing requirement does not include the area where the terminal is located, the first apparatus can determine that there is no terminal participating in the sensing. In this way, the first apparatus can accurately determine whether there is terminal participating in the sensing according to the sensing requirement. Moreover, in this manner, whether there is terminal participating in the sensing is determined by the first apparatus, and the first apparatus and other apparatuses can not transmit indication information for indicating whether there is terminal participating in the sensing, thereby reducing signaling overhead and saving transmission resources.

[0220] In some implementations, in a case that there is terminal participating in the sensing, the first apparatus can send a first request; correspondingly, the sensing management network element can receive the first request. The first request can be used to request the position of the at least one terminal. For example, in a case that the first indication information indicates that there is terminal participating in the sensing, the first apparatus can send the first request to the sensing management network element. For another example, in a case that the first apparatus determines by itself that there is terminal participating in the sensing, the first apparatus can send the first request to the sensing management network element.

[0221] Alternatively, after receiving the first request, the sensing management network element can send information for indicating the position of the at least one terminal; correspondingly, the first apparatus can receive the information for indicating the position of the at least one terminal. It should be understood that, in a case that the at least one terminal includes a plurality of terminals, the information for indicating the position of different terminals in the at least one terminal can be carried in a same message or can be carried in different messages, which is not limited. In this way, the first apparatus can accurately determine the position of the at least one terminal, thereby performing the manner f1 described above.

[0222] For example, the first request can include indication information of the at least one terminal, e.g., the first request can include an identifier of the at least one terminal. In this way, the sensing management network element can send the information for indicating the position of the at least one terminal according to the indication information of the at least one terminal, thereby avoiding unnecessary sending of the information for indicating the position of the at least one terminal, and further saving transmission resources.

[0223] In some other implementations, in a case that there is terminal participating in the sensing, the first apparatus can obtain the position of the at least one terminal saved locally, thereby performing the manner f1 described above.

[0224] It should be understood that the above implementations can be independent or combined with each other. For example, in the case where the terminal participates in the sensing, the first device can obtain the positions of the first part of the terminals in the at least one terminal stored locally, and request the positions of the terminals other than the first part of the terminals in the at least one terminal through the first request.

[0225] In yet another implementation, in the case where the terminal participates in the sensing and the positions of the at least one terminal are not obtained, the first device can send a second request; correspondingly, the sensing management network element can receive the second request. The second request can be used to request the first sensing data, and the specific content of the first sensing data can refer to the description of the first sensing data in step A2 above, and will not be described herein again. For example, in the case where the first indication information indicates that the terminal participates in the sensing and the positions of the at least one terminal are not obtained, the first device can send the second request to the sensing management network element. For another example, in the case where the first device determines by itself that the terminal participates in the sensing and the positions of the at least one terminal are not obtained, the first device can send the second request to the sensing management network element.

[0226] The positions of the at least one terminal not obtained can include, but are not limited to, one or more of the following cases: the first device does not store the positions of the at least one terminal locally; the sensing management network element does not send information indicating the positions of the at least one terminal after the first device sends the first request; although the sensing management network element sends information indicating the positions of the at least one terminal after the first device sends the first request, the first device does not receive the information indicating the positions of the at least one terminal. The reason why the first device does not receive the information indicating the positions of the at least one terminal can include, for example, that the link between the first device and the sensing management network element is interrupted.

[0227] Optionally, after receiving the second request, the sensing management network element can perform step A2 above. In this way, the sensing management network element can send the first sensing data to the first device in a targeted manner based on the request of the first device, so as to avoid unnecessary sending of the first sensing data, and thus transmission resources can be saved.

[0228] In some possible manners, the method shown in FIG. 9 can further include S904:

[0229] S904: The first device obtains second sensing data.

[0230] In some implementations, in the case where the positions of the at least one terminal are obtained, the second sensing data can be a result of processing the sensing data of the at least one terminal in manner f1; or the second sensing data is obtained according to the sensing data of the at least one terminal; or the second sensing data corresponds to (or is related to or associated with) the sensing data of the at least one terminal.

[0231] Optionally, the second perception data can be obtained by fusing perception data of the at least one terminal according to the position of the at least one terminal; or the first device can fuse the perception data of the at least one terminal according to the position of the at least one terminal to obtain the second perception data. For details, refer to the description of "the first device can fuse the perception data of the at least one terminal according to the position of the at least one terminal" in the manner f1, which will not be repeated herein. The type of the perception data obtained by fusing the perception data of the at least one terminal and the type of the second perception data can be the same or different. For example, in the first example in the manner f1 above, the perception data obtained by fusing the perception data of the at least one terminal is fused perception data of type I / Q signal; the second perception data can be fused perception data of type I / Q signal, or can be a result obtained by processing the fused perception data of type I / Q signal (for example, perception data of type CFR information or point cloud information). For another example, in the second example in the manner f1 above, the perception data obtained by fusing the perception data of the at least one terminal is fused perception data of type CFR information; the second perception data can be fused perception data of type CFR information, or can be a result obtained by processing the fused perception data of type CFR information (for example, perception data of type point cloud information).

[0232] For example, the second perception data can be obtained by fusing the perception data of the at least one terminal and the third perception data obtained by the access network side perception according to the position of the at least one terminal; or the first device can fuse the perception data of the at least one terminal and the third perception data obtained by the access network side perception according to the position of the at least one terminal to obtain the second perception data. The specific content can refer to the description of "the first device can fuse the perception data of the at least one terminal and the third perception data obtained by the access network side perception according to the position of the at least one terminal" in the manner f1, and will not be described here. The type of the perception data obtained by fusing the perception data of the at least one terminal and the third perception data can be the same as or different from the type of the second perception data. For example, in the third example in the manner f1 above, the perception data obtained by fusing the perception data of the at least one terminal and the third perception data is the fused perception data of the type of I / Q signal; the second perception data can be the fused perception data of the type of I / Q signal, or can be the result obtained by processing the fused perception data of the type of I / Q signal (for example, the perception data of the type of CFR information or point cloud information). For another example, in the fourth example in the manner f1 above, the perception data obtained by fusing the perception data of the at least one terminal and the third perception data is the fused perception data of the type of CFR information; the second perception data can be the fused perception data of the type of CFR information, or can be the result obtained by processing the fused perception data of the type of CFR information (for example, the perception data of the type of point cloud information). For another example, in the fifth example in the manner f1 above, the perception data obtained by fusing the perception data of the at least one terminal and the third perception data is the 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 the result obtained by processing the fused perception data of the type of point cloud information. In this example, the first device can obtain the second perception data according to the perception data from multiple devices, so that the perception processing can be performed according to more comprehensive perception data, and the perception performance can be improved.

[0233] Optionally, in this implementation, the perception data of the at least one terminal and the third perception data can be transmitted on different interfaces, 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 third perception data can be the perception data of a third device. The third device can send the perception data of the at least one terminal to the first device and can also send the third perception data to the first device. As described above, the interface between the first device and the third device can include two types of interfaces, one type of interface can be used to transmit the perception data of the terminal, and the other type of interface can be used to transmit the perception data of the access network side, in which case the perception data of the at least one terminal and the third perception data can be transmitted on different interfaces; or the interface between the first device and the third device can include one interface, a part of the logical links on the interface can be used to transmit the perception data of the terminal, and another part of the logical links can be used to transmit the perception data of the access network side, in which case the perception data of the at least one terminal and the third perception data can be transmitted on different logical links on the same interface; or the interface between the first device and the third device includes one interface, the data packets transmitted on the interface can contain or be associated with information indicating the type of data contained in the data packets, in which case the perception data of the at least one terminal and the third perception data can be contained in different data packets. For another example, in scenario 2 above, the third perception data can be the perception data of a second device. The second device can send the perception data of the at least one terminal to the first device and can also send the third perception data to the first device. As described above, the interface between the first device and the second device can include two types of interfaces, one type of interface can be used to transmit the perception data of the terminal, and the other type of interface can be used to transmit the perception data of the access network side, in which case the perception data of the at least one terminal and the third perception data can be transmitted on different interfaces; or the interface between the first device and the second device can include one interface, a part of the logical links on the interface can be used to transmit the perception data of the terminal, and another part of the logical links can be used to transmit the perception data of the access network side, in which case the perception data of the at least one terminal and the third perception data can be transmitted on different logical links on the same interface; or the interface between the first device and the second device includes one interface, the data packets transmitted on the interface can contain or be associated with information indicating the type of data contained in the data packets, in which case the perception data of the at least one terminal and the third perception data can be contained in different data packets. In this way, the first device can accurately determine whether the received perception data is the perception data of the at least one terminal or the third perception data sensed by the access network side.

[0234] In some implementations, the second perception data can be the first perception data. Optionally, in the case that the position of the at least one terminal is not acquired, the second perception data can be the first perception data. The specific content of the first perception data can refer to the description of the first perception data in step A2, and will not be repeated here.

[0235] In yet some implementations, the second perception data can be the result of processing the first perception data in step A3 above; or, the second perception data can be obtained according to the first perception data; or, the second perception data corresponds to (or is related to or associated with) the first perception data. The specific content of the first perception data can refer to the description of the first perception data in step A2, and will not be repeated here. Optionally, this implementation can be applicable to the case that the position of the at least one terminal is not acquired.

[0236] In some examples, the second perception data can be the second type of perception data obtained by processing the first type of first perception data; or, the first device can process the first type of first perception data to obtain the second type of second perception data, and the specific content can refer to the description of “the first device can process the first type of first perception data to obtain the second type of perception data” in step A3, and will not be repeated here. For example, in example six in step A3 above, the second perception data can be the perception data of the type of CFR information or RAV spectrum information. For another example, in example seven in step A3 above, the second perception data can be the perception data of the type of point cloud information.

[0237] In some examples, the second perception data can be obtained by fusing the first perception data and third perception data obtained by the access network side. In some examples, the first device can fuse the first perception data and third perception data obtained by the access network side to obtain the second perception data. The details can be referred to the description of the first device fusing the first perception data and third perception data obtained by the access network side in step A3, and will not be repeated here. The type of the perception data obtained by fusing the first perception data and third perception data can be the same as or different from the type of the second perception data. For example, the perception data obtained by fusing the first perception data and third perception data can be fused perception data of type I / Q signal; the second perception data can be fused perception data of type I / Q signal, or can be a result obtained by processing the fused perception data of type I / Q signal (for example, perception data of type CFR information or point cloud information). For another example, the perception data obtained by fusing the first perception data and third perception data can be fused perception data of type CFR information; the second perception data can be fused perception data of type CFR information, or can be a result obtained by processing the fused perception data of type CFR information (for example, perception data of type point cloud information). For another example, the perception data obtained by fusing the first perception data and third perception data can be fused perception data of type point cloud information; the second perception data can be fused perception data of type point cloud information, or can be a result obtained by processing the fused perception data of type point cloud information. In this example, the first device can obtain the second perception data according to the perception data from multiple devices, so that the perception processing can be performed according to more comprehensive perception data, and the perception performance can be improved.

[0238] In some possible manners, the method shown in FIG. 9 can further include S905:

[0239] S905: The first device sends the second perception data.

[0240] The second perception data can correspond to (or be related to or associated with) the perception data of the at least one terminal. The specific content of the second perception data can be referred to the description of the second perception data in S904, and will not be repeated here.

[0241] In some implementations, the first device can send the second sensing data to the perception management network element; correspondingly, the perception management network element can receive the second sensing data from the first device, as shown in S905a. For example, in scenario 1 above, the first device can send the second sensing data to the perception management network element by at least one of the manners a1-a8. Also for example, in scenario 2 above, the first device can send the second sensing data to the perception management network element by at least one of the manners d1-d8. With this implementation, the perception management network element can accurately obtain the second sensing data, and thus can perform more effective perception management according to the second sensing data.

[0242] Optionally, in this implementation, in the case that the first device sends the second sensing data to the perception management network element through 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. Also for 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.

[0243] In other implementations, the first device can send the second sensing data to the second device; correspondingly, the second device can receive the second sensing data from the first device, as shown in S905b. The second sensing data can be used to assist communication. For example, in scenario 1 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 sensing data to the second logical unit, and the second logical unit can perform communication according to the second sensing data. Also for example, in scenario 2 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 sensing data to the second access network device, and the second access network device can perform communication according to the second sensing data.

[0244] Optionally, the first device can further send information indicating the type of the second sensing data to the second device. In this way, the second device can accurately determine the type of the second sensing data. Exemplarily, the type of the second sensing data can include at least one of the following: point cloud information or perception target information.

[0245] In yet some implementations, the first apparatus can send the second sensing data to a third-party server; correspondingly, the third-party server can receive the second sensing data from the first apparatus. Through this implementation, the third-party server can accurately obtain the second sensing data. The present application does not limit the manner in which the third-party server uses the second sensing data, for example, the third-party server can use the second sensing data in artificial intelligence (AI) and / or digital twin.

[0246] It should be understood that the above implementations can be independent or can also be combined. In the case of combining the above implementations, the first apparatus can send the second sensing data to multiple apparatuses together, or can send the second sensing data to multiple apparatuses respectively. For example, the time instants at which the second sensing data is sent to different apparatuses can be the same or different, for example, the time instant at which the second sensing data is sent to the sensing management network element can be the same or different from the time instant at which the second sensing data is sent to the second apparatus; and / or, the second sensing data sent to different apparatuses can be carried in the same message or can be carried in different messages, for example, the second sensing data sent to the sensing management network element and the second sensing data sent to the second apparatus can be carried in the same message or can be carried in different messages.

[0247] In some possible manners, the method shown in FIG. 9 can further include S906-S907:

[0248] S906: The first apparatus can receive first information, the first information can indicate the first sensing requirement.

[0249] In some possible manners, the sensing management network element can send the first information, and correspondingly, the first apparatus can receive the first information from the sensing management network element, as shown in S906a. Through this manner, the first apparatus can obtain the first sensing requirement from the sensing management network element.

[0250] In other possible manners, the second apparatus can send the first information; correspondingly, the first apparatus can receive the first information from the second apparatus, as shown in S906b. For example, in the above scenario 1, in the case that the first apparatus is the first logical unit and the second apparatus is the second logical unit, the first logical unit can receive the first information from the second logical unit. For another example, in the above scenario 2, in the case that the first apparatus is the first access network device and the second apparatus is the second access network device, the first access network device can receive the first information from the second access network device. Through this manner, the first apparatus can obtain the first sensing requirement from the second apparatus on the access network side, thereby improving the management efficiency of the access network for sensing and reducing the time delay of obtaining the first sensing requirement.

[0251] Optionally, the first awareness requirement comprises at least one of the following information, or the first information indicates at least one of the following information: an awareness QoS or SLA; a type of awareness data; a time of awareness; or, an area of awareness. Details are as follows.

[0252] 1. An awareness QoS or SLA: can be used to indicate a required QoS or SLA for awareness. Exemplarily, the awareness QoS or SLA can comprise 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 a distance and / or range that can be detected; the accuracy can be a difference between an awareness result and actual data, e.g., one or more of a distance difference, an angle difference, or a speed difference; the resolution can be a minimum difference of different awareness results in one or more of a distance, an angle, or a speed dimension; the detection / false alarm probability refers to a probability of detecting a presence or absence of a target; the service latency refers to a time interval between an event occurrence or triggering awareness and outputting an awareness result; and the refresh rate can be a rate of refreshing awareness data, e.g., positioning data.

[0253] 2. A type of awareness data: can be used to indicate a type of data to be aware of. Exemplarily, the type of awareness data can comprise at least one of the following: an I / Q signal, RAV spectrum information, CFR information, point cloud information, or awareness target information. Here, multiple possible manners of the type of awareness data are provided, so that the type of awareness data can be flexibly configured.

[0254] 3. A time of awareness: can be used to indicate a time of awareness. For example, if the time of awareness comprised in the first awareness requirement is a first time period, it means that awareness is to be performed in the first time period. The time of awareness can be an absolute time, or can be a relative time with respect to a reference time, without limitation.

[0255] 4. An area of awareness: can be used to indicate an area of awareness. For example, if the area of awareness indicated by the first information is a first area, it means that awareness is to be performed in the first area, or means that targets in the first area are to be aware of. Optionally, the area of awareness can be indicated in multiple manners. In some examples, the area of awareness can be indicated by coordinates of the area. In other examples, the area of awareness can be indicated by an administrative area, e.g., if the administrative area is A city, it means that awareness is to be performed in the A city. In yet other examples, the area of awareness can be indicated by an identifier of one or more cells, e.g., if the identifier of the one or more cells comprises identifiers of cell #1 and cell #2, it means that awareness is to be performed in a coverage (or service) range of the cell #1 and the cell #2. The area of awareness can be replaced by at least one of the following: a range of awareness or a location of awareness.

[0256] The method provides multiple possible ways for the first awareness requirement, so that the first awareness requirement can be flexibly configured.

[0257] The first information can also have other names, such as awareness service information or awareness requirement information, as long as it has the same function and is within the protection scope of the present application.

[0258] Optionally, S906 is before S901.

[0259] In some examples, when S906 is S906a and S903 is S903a, the execution order of S906a and S903a is not limited; the first information in S906a and the first indication information in S903a can be carried in the same message or in a new message, without limitation. In other examples, when S906 is S906b and S903 is S903b, the execution order of S906b and S903b is not limited; the first information in S906b and the first indication information in S903b can be carried in the same message or in a new message, without limitation.

[0260] S907: The first device can send second information; correspondingly, the second device can receive the second information.

[0261] For example, in scenario 1 above, when 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 information to the second logical unit. For another example, in scenario 2 above, when 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 information to the second access network device.

[0262] The second information can be used to determine the first awareness resource. The first awareness resource can be used for at least one terminal to send and / or receive an awareness signal; or the first awareness resource can be a resource for the at least one terminal to send and / or receive the awareness signal. The sending and / or receiving of the awareness signal corresponds to (or is related to or associated with) the second awareness requirement; or the sending and / or receiving of the awareness signal can be used to implement the second awareness requirement. The second awareness requirement is determined according to the first awareness requirement.

[0263] In some examples, the second awareness requirement can be the first awareness requirement.

[0264] In some examples, the second sensing requirement can include part of the first sensing requirement; or, the second sensing requirement can be a sub-requirement of the first sensing requirement; or, the second sensing requirement can be a result of the first sensing requirement being split (or divided) by the first device. For example, in the first sensing requirement, the sensed area includes area #1 in cell #1 and area #1 in cell #2. Cell #1 is a cell of CU #1, and cell #2 is a cell of CU #2. The first sensing requirement can be divided into second sensing requirement #1 and second sensing requirement #2. In the second sensing requirement #1, the sensed area includes area #1 in cell #1; and in the second sensing requirement #2, the sensed area includes area #1 in cell #2. For another example, in the first sensing requirement, the sensed area includes area #1 in cell #1 and area #1 in cell #2. Cell #1 is a cell of NodeB #1, and cell #2 is a cell of NodeB #2. The first sensing requirement can be divided into second sensing requirement #1 and second sensing requirement #2. In the second sensing requirement #1, the sensed area includes area #1 in cell #1; and in the second sensing requirement #2, the sensed area includes area #1 in cell #2. For yet another example, in the first sensing requirement, the sensed time 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 sensing requirement can be divided into second sensing requirement #3 and second sensing requirement #4. In the second sensing requirement #3, the sensed time includes time period #1, and the sensed area includes the coverage of cell #1; and in the second sensing requirement #4, the sensed time includes time period #2, and the sensed area includes the coverage of cell #2. The traffic volume threshold can be pre-set, for example, specified by a protocol; or determined by the first device; or notified to the first device by another device (for example, a core network device).

[0265] The specific content of the second sensing requirement can refer to the description of the first sensing requirement in S901, except that the first sensing requirement is replaced by the second sensing requirement, which will not be repeated here.

[0266] Optionally, S907 is before S901.

[0267] In this way, after receiving the first information indicating the first sensing requirement, the first device at the access network side can send the second information for determining 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 easily obtain the condition of the resource at the access network side, the 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.

[0268] 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.

[0269] As described above, the second information is used to determine the first sensing resource, and the determination manner can be various, for example, the manner g1 or the manner g2.

[0270] Manner g1: the second information indicates the first sensing resource. The present application does not limit the specific content of the second information indicating the first sensing resource.

[0271] 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.

[0272] Optionally, in this manner, 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 manner of determining the first sensing resource by the first device according to the second sensing requirement.

[0273] The second information can also have other names, for example, sensing resource configuration information, etc., as long as it has the same function, which is within the protection scope of the present application.

[0274] Through this manner, the second device can accurately determine the first sensing resource according to the second information. In this manner, the sensing resource can be determined by the first device at the access network side, thereby improving the flexibility of the first device for the sensing management, and further improving the efficiency of the sensing management.

[0275] Optionally, in the manner g1, the second information can further include first indication information, which indicates whether there is a terminal participating in sensing. The specific content of the first indication information can refer to the description of the first indication information in S903, and will not be repeated. In this way, the second device can accurately determine whether there is a terminal participating in sensing according to the first indication information.

[0276] In some implementations, in the manner g1, the method shown in FIG. 9 can further include the following step B1:

[0277] Step B1: the second device can send third information; correspondingly, the first device can receive the third information.

[0278] The third information can indicate a recommended and / or non-recommended sensing resource. Optionally, the recommended and / or non-recommended sensing resource can be a recommended and / or non-recommended sensing resource for the second device. For example, the recommended and / or non-recommended sensing resource can include at least one of a time domain resource, a frequency domain resource, a spatial domain resource, a code domain resource, or a power domain resource.

[0279] 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.

[0280] In some examples, the third information indicates a recommended sensing resource; and the first resource can belong to the recommended sensing resource, or the first device can select the first sensing resource from the recommended sensing resource. For example, if the recommended sensing resource indicated by the third information is a time domain resource on time unit #1 and time unit #2, the first sensing resource can include a time domain resource on time unit #1 and / or time unit #2. For another example, if the recommended sensing resource indicated by the third information is a frequency domain resource on frequency unit #1 and frequency unit #2, the first sensing resource can include a frequency domain resource on frequency unit #1 and / or frequency unit #2.

[0281] In 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.

[0282] In 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.

[0283] The third information can also have other names as long as it has the same function, which is within the protection scope of the present application.

[0284] Optionally, step B1 can be performed before S907. The present application does not limit the execution order of step B1 and S906. In S906, 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.

[0285] By this implementation, the first device can learn the recommended and / or non-recommended sensing resources, and thus can select appropriate sensing resources accordingly, and further can better satisfy the sensing requirement and improve the efficiency of sensing management.

[0286] In some other implementations, in the manner g1, the method shown in FIG. 9 can further include step B2:

[0287] Step B2: The second device can send first response information; correspondingly, the first device can receive the first response information.

[0288] 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, reception and / or transmission of the sensing signal of the first sensing resource for at least one terminal. “Acceptance or rejection” can be replaced by at least one of the following: whether to accept, whether to agree or whether to reject. By this 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.

[0289] Optionally, in the case that the first response information indicates rejection of the first sensing resource for implementing the second sensing requirement, the first response information can further indicate at least one of the following: the reason for rejection, or the CU-recommended and / or non-recommended sensing resource. This is described in detail below.

[0290] 1. The reason for rejection: used to indicate the reason for rejecting the first sensing resource for implementing the second sensing requirement. Optionally, the reason can be indicated by a cause value.

[0291] For example, the reason can include at least one of the following reasons a1 to a7:

[0292] Reason a1: Insufficient sensing time domain resources. For example, the available sensing time domain resources of the terminal served by the second device are less than the time domain resources in the first sensing resource.

[0293] Reason a2: Insufficient sensing frequency domain resources. For example, the available sensing frequency domain resources of the terminal served by the second device are less than the frequency domain resources in the first sensing resource.

[0294] Cause a3: Insufficient available sensing spatial domain resources. For example, the available sensing spatial domain resources of the terminals served by the second device are less than the spatial domain resources in the first sensing resources.

[0295] Cause a4: Insufficient available sensing code domain resources. For example, the available sensing code domain resources of the terminals served by the second device are less than the code domain resources in the first sensing resources.

[0296] Cause a5: Insufficient available sensing power domain resources. For example, the available sensing power domain resources of the terminals served by the second device are less than the power domain resources in the first sensing resources.

[0297] Cause a6: No terminal for sensing. For example, among the terminals served by the second device, there is no terminal for sensing; or, among the terminals served by the second device, there is no terminal with sensing function.

[0298] Cause a7: The terminal cannot meet the sensing QoS or SLA in the second sensing requirement. For example, the terminal served by the second device cannot meet the second sensing requirement.

[0299] 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 B1, which will not be repeated here.

[0300] Through the method, the first device can know the reason for refusing the first sensing resources to implement the second sensing requirement, and / or the recommended and / or non-recommended sensing resources, so as to adjust the second information accordingly, for example, the sensing requirement for the second device and / or the sensing resources configured for at least one terminal indicated by the second information can be adjusted, so that the adjusted second information (or the sensing resources determined according to the adjusted second information) is adapted to the resource situation on the terminal side, and then the sensing requirement can be met, the sensing performance is improved, and the efficiency of sensing management is improved.

[0301] Optionally, in the case that the first response information indicates that the first sensing resources are refused to implement the second sensing requirement, the first device can re-execute S907.

[0302] 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 the CU#1 after sending the second information to the CU#1, 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 the CU#2, the terminals served 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 first response information #1 from the NodeB#1 after sending the second information to the NodeB#1, 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 the NodeB#2, the terminals served by the NodeB#2 can implement the second sensing requirement.

[0303] 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 of rejection, and / or the recommended and / or un-recommended sensing resource; or the updated second information can correspond to (or be related to or associated with) the reason of rejection, and / or the recommended and / or un-recommended sensing resource. The following is an example in which the sensing resource indicated by the updated second information is the first sensing resource #1, and the sensing resource indicated by the second information before updating is the first sensing resource #2. For example, in the case where the reason of rejection includes insufficient sensing time domain resource, the time domain resource in the first sensing resource #1 can be less than the time domain resource in the first sensing resource #2; or in the case where the reason of rejection includes insufficient sensing time domain resource, the first device can reduce the time domain resource in the first sensing resource. For another example, the first sensing resource #2 includes un-recommended sensing resource, and the first sensing resource #1 does not include un-recommended sensing resource. For another example, the first sensing resource #2 does not belong to the recommended sensing resource, and the first sensing resource #1 belongs to the recommended sensing resource.

[0304] 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 resource for implementing the second sensing requirement), or sensing resource configuration failure / rejection message (in the case of indicating rejection of the first sensing resource for implementing the second sensing requirement). As long as they have the same function, they are within the protection scope of the present application.

[0305] Optionally, the step B1 and the step B2 can be independent or combined.

[0306] Optionally, the step B1 and / or the step B2 can be before the S901; and / or, the step B2 can be after the S907.

[0307] Optionally, in the manner g1, the second information can further indicate at least one of: a sensing transceiving mode; or, a sensing area. Details are as follows.

[0308] 1. The sensing transceiving mode: optionally, the sensing transceiving mode can be a sensing transceiving mode of at least one terminal. Exemplarily, the transceiving mode can be one of: a self-transceiving mode, an A-to-B transceiving mode, or a hybrid transceiving mode. Details can be referred to the description of the self-transceiving mode, the A-to-B transceiving mode, and the hybrid transceiving mode in the term explanation part, and will not be repeated here.

[0309] 2. The sensing area: optionally, the sensing area can be a sensing area of at least one terminal. Details can be referred to the description of the “sensing area” in the first sensing requirement in S906, and 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 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.

[0310] In this way, the second device can accurately determine the sensing transceiving mode and / or the sensing area according to the second information, thereby improving the sensing performance. Moreover, in this manner, the sensing transceiving mode and / or the sensing area can be indicated by the first device, thereby improving the flexibility of the first device in sensing management.

[0311] Manner g2: the second information indicates a second sensing requirement, and the second sensing requirement is used to determine the first sensing resource.

[0312] Details of the second sensing requirement can be referred to the description of the second sensing requirement in S907, and will not be repeated here.

[0313] 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.

[0314] In some possible manners, the second information can further indicate a sensing transceiving mode, and details can be referred to the description of the sensing transceiving mode in the manner g1, and will not be repeated here.

[0315] 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. Moreover, in this manner, the sensing resource can be determined by the second device on the access network side, thereby improving the flexibility of the second device in sensing management, and further improving the efficiency of the sensing management.

[0316] In some implementations, in the manner g2, the method shown in FIG. 9 can further include step C1:

[0317] Step C1: The second device can send the second response information; correspondingly, the first device can receive the second response information.

[0318] 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.

[0319] Optionally, in this implementation, the second response information can further indicate at least one of the following: a transceiving mode for sensing; or, a location for sensing. Details are described below.

[0320] 1. The transceiving mode for sensing: details can refer to the description of the transceiving mode for sensing in the manner g1, which will not be repeated here. In some examples, the transceiving mode for sensing indicated by the second response information can be the same as the transceiving mode for sensing indicated by the second information. In other examples, the transceiving mode for sensing indicated by the second response information can be different from the transceiving mode for sensing indicated by the second information. For example, the transceiving mode for sensing indicated by the second response information can belong to the transceiving mode for sensing indicated by the second information. For example, the transceiving mode for sensing indicated by the second information includes: self-transmitting and self-receiving mode and A-transmitting and B-receiving mode, and the transceiving mode for sensing indicated by the second response information can include: self-transmitting and self-receiving mode and / or A-transmitting and B-receiving mode.

[0321] 2. The sensing area: details can refer 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 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.

[0322] Optionally, step C1 can be before S901; and / or, step C1 can be after S907.

[0323] Through this method, the second response information can accurately indicate the transceiving mode for sensing and / or the sensing area, thereby improving the efficiency of sensing management and improving the sensing performance.

[0324] Optionally, in this implementation, the second device can send the second response information to the first device and send the first indication information to the first device; that is, step C1 can be combined with S903b in S903. In this case, the time at which the second device sends the second response information can be the same as or different from the time at which the second device sends the first indication information; and / or, the first indication information and the second response information can be carried in the same message or can be carried in different messages.

[0325] In other implementations, the second response information can indicate rejection (or disagreement or non-acceptance) of implementing the second sensing requirement. Through this implementation, the first device can accurately determine that the second device rejects implementing the second sensing requirement according to the second response information.

[0326] Optionally, in this implementation, the second response information can further indicate at least one of the following: a reason for rejection; recommended and / or non-recommended sensing resources; or, an implementable sensing requirement. This is described in detail below.

[0327] 1. A reason for rejection: used to indicate a reason for rejecting implementation of the second sensing requirement. Optionally, the reason can be indicated by a cause value.

[0328] For example, the reason can include at least one of the following reasons a1 to a7: reason a1: insufficient sensing time domain resources; reason a2: insufficient sensing frequency domain resources; reason a3: insufficient sensing space domain resources; reason a4: insufficient sensing code domain resources; reason a5: insufficient sensing power domain resources; reason a6: no terminal for sensing; and reason a7: the terminal does not meet the sensing QoS or SLA in the second sensing requirement. The specific content of reasons a1 to a7 can refer to the description of reasons a1 to a7 in step B2, and will not be described again.

[0329] 2. Recommended and / or non-recommended sensing resources: the specific content can refer to the description of recommended and / or non-recommended sensing resources in step B1, and will not be described again.

[0330] 3. Implementable sensing requirement: or called satisfied sensing requirement. Optionally, the implementable sensing requirement can be a sensing requirement that can be implemented by a terminal served by the second device, for example, a sensing QoS or SLA that can be met by a terminal served by the second device.

[0331] Through this method, the first device can learn one or more of the reason for rejecting implementation of the second sensing requirement, the recommended and / or non-recommended sensing resources, or the implementable sensing requirement, so as to adjust the sensing requirement for the second device accordingly, so that the adjusted sensing requirement is adapted to the resource situation on the terminal side served by the second device, and thus the sensing requirement can be met, the sensing performance can be improved, and the efficiency of sensing management can be improved.

[0332] Optionally, in case that the second response information indicates that the second awareness requirement is rejected, the first apparatus can re-perform S907.

[0333] In some implementations, the first apparatus can send the second information to another second apparatus. For example, the first apparatus 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, the second response information #1 indicates that the second awareness requirement is rejected. The first logical unit can send the second information to the CU#2, the terminals served by the CU#2 can implement the second awareness requirement. For another example, the first apparatus 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, the second response information #1 indicates that the second awareness requirement is rejected. The first access network device can send the second information to the NodeB#2, the terminals served by the NodeB#2 can implement the second awareness requirement.

[0334] In some other implementations, the first apparatus can send the updated second information to the second apparatus. 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 of rejection; the recommended and / or non-recommended awareness resource; or the implementable awareness requirement. The following is an example in which the awareness requirement indicated by the updated second information is the second awareness requirement #1, and the awareness requirement indicated by the second information before updating is the second awareness requirement #2. For example, in case that the reason of rejection includes the lack of awareness time domain resource, the awareness time domain resource required by the second awareness requirement #1 can be less than the awareness time domain resource required by the second awareness requirement #2; or in case that the reason of rejection includes the lack of awareness time domain resource, the first apparatus can reduce the time domain resource required by the second awareness requirement. For another example, the awareness resource required by the second awareness requirement #2 includes the non-recommended awareness resource, and the awareness resource required by the second awareness requirement #1 does not include the non-recommended awareness resource. For another example, the awareness resource required by the second awareness requirement #2 does not belong to the recommended awareness resource, and the awareness resource required by the second awareness requirement #1 belongs to the recommended awareness resource. For another example, the second awareness requirement #2 does not belong to the awareness requirement that can be implemented by the terminals served by the second apparatus, and the second awareness requirement #1 belongs to the awareness requirement that can be implemented by the terminals served by the second apparatus.

[0335] The second response information can have other names, such as the second feedback information, the awareness resource configuration response message, the awareness resource configuration completion / success message (in case of indicating the first awareness resource), or the awareness resource configuration failure / rejection message (in case of indicating that the second awareness requirement is rejected). As long as they have the same function, they are within the protection scope of the present application.

[0336] Optionally, in this mode, after determining the first sensing resource, the first device or the second device can notify the at least one terminal of the sensing resource. The first terminal can be any one of the at least one terminal. The following takes the first terminal as an example to describe the mode of obtaining the sensing resource by the at least one terminal.

[0337] In some implementations, the first device can send fourth information; correspondingly, the first terminal can receive the fourth information. The fourth information can indicate the second sensing resource, and the second sensing resource can be part or all of the first sensing resource. In some examples, in scenario 1 above, the first device can send the fourth information to the first terminal through the second device and the third device in sequence. For example, the first device is a SU, the second device includes a CU and a DU, and the third device is a RU. The SU can send the fourth information to the first terminal through the CU, the DU and the RU in sequence. For another example, the first device is a SU, the second device includes a CU, and the third device is a RU. The SU can send the fourth information to the first terminal through the CU and the RU in sequence. For another example, the first device is a SU, the second device includes a DU, and the third device is a RU. The SU can send the fourth information to the first terminal through the DU and the RU in sequence. In other examples, in scenario 1 above, the first device can send the fourth information to the first terminal through the third device. For example, the first device is a SU, and the third device is a RU. The SU can send the fourth information to the first terminal through the RU. In yet other examples, in scenario 2 above, the first device can send the fourth information to the first terminal through the second device. For example, the first device is a NodeC, and the second device is a NodeB. The NodeC can send the fourth information to the first terminal through the NodeB.

[0338] In other implementations, the second device can send the fourth information; correspondingly, the first terminal can receive the fourth information. The fourth information can indicate the second sensing resource, and the second sensing resource can be part or all of the first sensing resource. In some examples, in scenario 1 above, the second device can send the fourth information to the at least one terminal through the third device. For example, the second device includes a CU, and the third device is a RU. The CU can send the fourth information to the first terminal through the DU and the RU in sequence. For another example, the second device includes a DU, and the third device is a RU. The DU can send the fourth information to the first terminal through the RU. In other examples, in scenario 2 above, the second device can send the fourth information to the first terminal. For example, the second device is a NodeB. The NodeB can send the fourth information to the first terminal.

[0339] In this way, the first terminal can determine the second sensing resource for sensing, so that the second sensing resource can be used to transmit and / or receive the sensing signal, and further, the sensing data corresponding to the sensing signal can be obtained. In a similar way, each terminal of the at least one terminal can transmit and / or receive the sensing signal according to the corresponding sensing resource, so as to obtain the sensing data of the at least one terminal, and further, S901 can be executed.

[0340] Optionally, the fourth information can further indicate at least one of: a transceiving mode for sensing; or, a sensing area. Details are as follows.

[0341] 1. The transceiving mode for sensing: details can be referred to the description of the transceiving mode for sensing in g1, and will not be repeated here. In some examples, the transceiving mode for sensing indicated by the fourth information can be the same as the transceiving mode for sensing indicated by the second information. In other examples, the transceiving mode for sensing indicated by the fourth information can be different from the transceiving mode for sensing indicated by the second information. For example, the transceiving mode for sensing indicated by the fourth information can belong to the transceiving mode for sensing indicated by the second information. For example, the transceiving mode for sensing indicated by the second information includes: self-transmitting and self-receiving mode and A-transmitting and B-receiving mode, and the transceiving mode for sensing indicated by the fourth information can include: self-transmitting and self-receiving mode and / or A-transmitting and B-receiving mode.

[0342] For example, if the transceiving mode is self-transmitting and self-receiving mode, the first terminal can transmit the sensing signal according to the second sensing resource, and receive the sensing signal. For example, if the transceiving mode is A-transmitting and B-receiving mode, the first terminal can transmit the sensing signal according to the second sensing resource, or the first terminal can receive the sensing signal according to the second sensing resource. For example, if the transceiving mode is a hybrid transceiving mode, the first terminal can transmit sensing signal #1 according to the second sensing resource, receive sensing signal #1, and receive sensing signal #2 transmitted by other devices (e.g., RUs or other terminals).

[0343] 2. The sensing area: details can be referred to the description of the sensing area in the first sensing requirement in S906, and will not be repeated here. In some examples, the sensing area indicated by the fourth information can be the same as the sensing area in the second sensing requirement. In other examples, the sensing area indicated by the fourth information can be different from the sensing area in the second sensing requirement. For example, the sensing area indicated by the fourth information can belong to the sensing area in the second sensing requirement.

[0344] For example, the first terminal can receive and / or transmit the sensing signal in the sensed area indicated by the fourth information. For another example, the first terminal can transmit the sensing signal to the sensed area indicated by the fourth information; and / or, the first terminal can receive the sensing signal from the sensed area indicated by the fourth information.

[0345] In some other possible manners, the method shown in FIG. 9 can further include S908-S909.

[0346] S908: The sensing management network element obtains the first sensing requirement.

[0347] Optionally, the sensing management network element can obtain the first sensing requirement from the AF; or, the sensing management network element can receive the first sensing requirement from the AF.

[0348] The specific content of the first sensing requirement can refer to the description of the first sensing requirement in S906, and will not be repeated here.

[0349] S909: The sensing management network element can send the second information; correspondingly, the second device can receive the second information.

[0350] The second information can be used to determine the first sensing resource, which is used for at least one terminal to send and / or receive the sensing signal corresponding to the second sensing requirement determined according to the first sensing requirement. The specific content of the second information can refer to the description of the second information in S907, except that the first device is replaced by the sensing management network element, and will not be repeated here.

[0351] Optionally, in this manner, after determining the first sensing resource, the second device can notify the at least one terminal of the sensing resource, and the notification manner can refer to the description of “the second device can notify the at least one terminal of the sensing resource” in S907, and will not be repeated here. In this way, each terminal in the at least one terminal can send and / or receive the sensing signal according to the corresponding sensing resource, so as to obtain the sensing data of the at least one terminal, and then S901 can be executed.

[0352] Optionally, S908 and S909 are before S901.

[0353] Through this manner, the second device on the access network side can negotiate the first sensing resource with the sensing management network element. Since the second device on the access network side can conveniently obtain the condition of the resource on the access network side, the sensing resource that is suitable for the condition of the access network side can be determined, and then the sensing requirement can be met, the sensing performance can be improved, and the efficiency of the sensing management can be improved.

[0354] In the method shown in FIG. 9, the first device can process the sensing data of the at least one terminal according to whether the position of the at least one terminal is acquired. In one case, the first device can acquire the position of the at least one terminal, and thus can process the sensing data of the at least one terminal according to the position of the at least one terminal. In this case, the position of the at least one terminal can be a reference position of the at least one terminal, instead of an actual position of the at least one terminal. Since the position of the terminal is the privacy of the terminal, the method can improve the performance of the sensing processing while ensuring the privacy of the terminal.

[0355] In addition, in the method, the first device can be used for sensing, and the first device can be independent of the device (e.g., the second device and / or the third device) used for communication by the access network side, so that the scalability of the first device can be improved, and thus the first device can be upgraded to meet higher sensing requirements.

[0356] Embodiments of the present application provide another communication method. FIG. 10 is a flowchart of a communication method provided by an embodiment of the present application. The specific content of the execution subject of the method shown in FIG. 10 can be referred to the description of the execution subject of the method shown in FIG. 9, and will not be repeated here. In the method shown in FIG. 10, the first device can process the sensing data of the at least one terminal according to the position of the at least one terminal. As shown in FIG. 10, the method includes:

[0357] S1001: The at least one terminal sends the sensing data of the at least one terminal; and correspondingly, the first device receives the sensing data of the at least one terminal.

[0358] The specific content of S1001 can be referred to S901, and will not be repeated here.

[0359] S1002: The first device can process the sensing data of the at least one terminal according to the position of the at least one terminal.

[0360] The specific content of S1002 can be referred to the manner f1 in S902, and will not be repeated here.

[0361] In some possible manners, the method shown in FIG. 10 can further include:

[0362] S1003: The first device receives first indication information, and the first indication information indicates whether there is a terminal participating in sensing.

[0363] The specific content of S1003 can be referred to S903, and will not be repeated here.

[0364] In other possible manners, the first device can determine whether there is a terminal participating in sensing by itself, and the specific content can be referred to the description of “the first device can determine whether there is a terminal participating in sensing by itself” in the method shown in FIG. 9, and will not be repeated here.

[0365] In some implementations, the first apparatus can send the first request in a case that the terminal participates in the sensing; correspondingly, the sensing management network element can receive the first request. The first request can be used to request the position of the at least one terminal. For details, refer to the description of "the first apparatus can send the first request in a case that the terminal participates in the sensing" in the method shown in FIG. 9, which will not be repeated here.

[0366] Optionally, after receiving the first request, the sensing management network element can send information indicating the position of the at least one terminal; correspondingly, the first apparatus can receive the information indicating the position of the at least one terminal. For details, refer to the description of "the sensing management network element can send information indicating the position of the at least one terminal" in the method shown in FIG. 9, which will not be repeated here. After receiving the information indicating the position of the at least one terminal, the first apparatus can perform S1002.

[0367] In some other implementations, the first apparatus can obtain the locally saved position of the at least one terminal in a case that the terminal participates in the sensing, thereby performing S1002.

[0368] It should be understood that the above implementations can be independent or combined with each other. For example, in a case that the terminal participates in the sensing, the first apparatus can obtain the position of a first part of the at least one terminal locally saved, and request the position of the terminal other than the first part of the at least one terminal through the first request.

[0369] In some possible manners, the method shown in FIG. 10 can further include:

[0370] S1004: The first apparatus obtains second sensing data.

[0371] The second sensing data can be a result of processing the sensing data of the at least one terminal in S1002. For details of the second sensing data, refer to the description of "the second sensing data can be a result of processing the sensing data of the at least one terminal in manner f1" in S904, which will not be repeated here.

[0372] In some possible manners, the method shown in FIG. 10 can further include S1005:

[0373] S1005: The first apparatus sends the second sensing data.

[0374] For details of S1005, refer to S905, which will not be repeated here.

[0375] In some possible manners, the method shown in FIG. 10 can further include S1006 to S1007:

[0376] S1006: The first device can receive first information, which can indicate the first sensing requirement.

[0377] S1007: The first device can send second information; correspondingly, the second device can receive the second information. The second information can be used to determine the first sensing resource.

[0378] The specific contents of S1006 to S1007 can refer to S906 to S907, and will not be described herein again.

[0379] In some other possible manners, the method shown in FIG. 10 can further include S1008 to S1009:

[0380] S1008: The sensing management network element obtains the first sensing requirement.

[0381] S1009: The sensing management network element can send second information; correspondingly, the second device can receive the second information. The second information can be used to determine the first sensing resource.

[0382] The specific contents of S1008 to S1009 can refer to S908 to S909, and will not be described herein again.

[0383] Through the method shown in FIG. 10, the first device on the access network side can process the sensing data of the at least one terminal according to the position of the at least one terminal, so that the processing of the sensing data of the terminal by the access network side can be realized. Compared with the processing of the sensing data of the terminal by the core network device or the third-party server, the method can reduce the processing delay of the sensing data of the terminal.

[0384] In addition, in the method, the position of the at least one terminal obtained by the first device can be the reference position of the at least one terminal, rather than the actual position of the at least one terminal. The actual position of the terminal belongs to the privacy of the terminal. Therefore, through the method, the processing delay of the sensing data of the terminal is reduced and the performance of the sensing processing is improved while ensuring the privacy of the at least one terminal.

[0385] In addition, in the method, the first device can be used for sensing, and the device used for communication on the access network side is independent, so that the scalability of the first device can be improved, and the first device can be upgraded to meet higher sensing requirements.

[0386] Embodiments of the present application provide another communication method. FIG. 11 is a flowchart of a communication method provided by an embodiment of the present application. The specific contents of the execution subject of the method shown in FIG. 11 can refer to the description of the execution subject of the method shown in FIG. 9, and will not be described herein again. In the method shown in FIG. 11, the first device can receive first sensing data, which is obtained by processing the sensing data of at least one terminal according to the position of the at least one terminal. As shown in FIG. 11, the method includes:

[0387] S1101: The perception management network element sends first perception data; correspondingly, the first device receives the first perception data.

[0388] The first perception data is obtained by processing perception data of at least one terminal according to a position of the at least one terminal.

[0389] The specific content of S1101 can refer to step A2, and repeated parts will not be described herein.

[0390] Optionally, before sending the first perception data, the perception management network element can obtain perception data of at least one terminal, and the obtaining manner can be various, for example, at least one of the manners h1 to h3.

[0391] The manner h1: The at least one terminal can sequentially send perception data of the at least one terminal to the perception management network element through the third device and the second device. Optionally, the manner h1 can be applicable to the above scenario 1.

[0392] The first terminal can be any terminal in the at least one terminal. The manner h1 is described below by taking the first terminal as an example.

[0393] For example, the second device includes a CU and a DU, and the third device is an RU. The first terminal can sequentially send perception data of the first terminal to the perception management network element through the RU, the DU and the CU.

[0394] For another example, the second device includes a CU, and the third device is an RU. The first terminal can sequentially send perception data of the first terminal to the perception management network element through the RU and the CU.

[0395] For another example, the second device includes a DU, and the third device is an RU. The first terminal can sequentially send perception data of the first terminal to the perception management network element through the RU and the DU.

[0396] Optionally, in this manner, the perception data received by the second device can be perception data of the at least one terminal or third perception data sensed by the access network side (for example, the third device). In the case where the perception data received by the second device is the perception data of the at least one terminal, the second device can send the perception data of the at least one terminal to the perception management network element; and / or in the case where the perception data received by the second device is the third perception data sensed by the access network side, the second device can send the third perception data to the first device. In this way, the second device can determine a suitable transmission path for the received perception data, so as to reduce the transmission delay of the perception data.

[0397] Optionally, in this way, the perception data of the at least one terminal and the third perception data can be transmitted on different interfaces, or can be transmitted on different logical links on the same interface, or can be contained in different data packets. For details, refer to the description of "the perception data of the at least one terminal and the third perception data can be transmitted on different interfaces, or can be transmitted on different logical links on the same interface, or can be contained in different data packets" in S904. In this way, the second device can accurately determine whether the received perception data is the perception data of the at least one terminal or the third perception data sensed by the access network side.

[0398] Way h2: The at least one terminal can send the perception data of the at least one terminal to the perception management network element through the second device. Optionally, this way h2 can be applied to the above scenario 2.

[0399] The first terminal can be any terminal of the at least one terminal. The following describes way h2 by taking the first terminal as an example. For example, the second device includes a NodeB. The first terminal can send the perception data of the first terminal to the perception management network element through the NodeB.

[0400] Optionally, in this way, the perception data obtained by the second device can be the perception data of the at least one terminal or the third perception data sensed by the access network side (for example, the second device). In the case where the perception data obtained by the second device is the perception data of the at least one terminal, the second device can send the perception data of the at least one terminal to the perception management network element; and / or, in the case where the perception data obtained by the second device is the third perception data sensed by the access network side, the second device can send the third perception data to the first device. In this way, the second device can determine a suitable transmission path for the received perception data, so as to reduce the transmission delay of the perception data.

[0401] Way h3: The at least one terminal can send the perception data of the at least one terminal to the perception management network element through the first device. Optionally, this way h3 can be applied to the above scenario 1 and scenario 2.

[0402] Way h3 can include steps D1 to D2:

[0403] Step D1: The at least one terminal sends the perception data of the at least one terminal; correspondingly, the first device receives the perception data of the at least one terminal.

[0404] The specific content of step D1 can refer to S901, which will not be described here.

[0405] Step D2: The first device can send the perception data of the at least one terminal; correspondingly, the perception management network element can receive the perception data of the at least one terminal.

[0406] The specific content of step D2 can refer to the description of "the first device can send the perception data of the at least one terminal; correspondingly, the perception management network element can receive the perception data of the at least one terminal" in step A1 in S902, and will not be repeated here.

[0407] S1102: The first device communicates according to the second perception data.

[0408] In some implementations, the second perception data is the first perception data.

[0409] In other implementations, the second perception data corresponds to (or is related to or associated with) the first perception data; or, the second perception data is obtained according to the first perception data; or, the second perception data is a result of processing the first perception data.

[0410] In some examples, the specific content of the second perception data can refer to the description of the second perception data in "the second perception data can be a result of processing the first perception data in step A3 above" in S904, and will not be repeated here.

[0411] In other examples, the second perception data can be obtained by processing the first perception data according to the position of the at least one terminal; or, the first device can process the first perception data according to the position of the at least one terminal to obtain the second perception data. There are various ways for the first device to obtain the position of the at least one terminal. For example, in the case where the terminal participates in perception, the first device can send a first request; correspondingly, the perception management network element can receive the first request, and the first request can be used to request the position of the at least one terminal. The specific content can refer to the description of "in the case where the terminal participates in perception, the first device can send a first request; correspondingly, the perception management network element can receive the first request" in the method shown in FIG. 9, and will not be repeated here. After receiving the first request, the perception management network element can send information indicating the position of the at least one terminal; correspondingly, the first device can receive the information indicating the position of the at least one terminal. Also for example, in the case where the terminal participates in perception, the first device can obtain the locally saved position of the at least one terminal. It should be understood that the above examples can be independent or combined with each other. For example, in the case where the terminal participates in perception, the first device can obtain the position of a first part of the at least one terminal locally saved, and request the position of the terminals other than the first part of the at least one terminal through the first request.

[0412] Optionally, S1102 can include step E1:

[0413] Step E1: The first device can send the second perception data.

[0414] For details on step E1, please refer to S905, which will not be repeated here.

[0415] Among some possible approaches, the method shown in Figure 11 may also include:

[0416] S1103: The first device receives first instruction information, which indicates whether a terminal is involved in sensing.

[0417] For details of S1103, please refer to S903; further details will not be provided here.

[0418] In some other possible approaches, the first device can determine on its own whether a terminal is involved in sensing. For details, please refer to the explanation of "the first device can determine on its own whether a terminal is involved in sensing" in the method shown in Figure 9, which will not be repeated here.

[0419] In some implementations, when a terminal is involved in sensing, the first device can send a second request; correspondingly, the sensing management network element can receive the second request. The second request can be used to request the first sensing data. For details, please refer to the explanation of "the first device can send a second request; correspondingly, the sensing management network element can receive the second request" in the method shown in Figure 9, which will not be repeated here.

[0420] Optionally, after receiving the second request, the sensing management network element may execute S1101. In this way, the sensing management network element can send the first sensing data to the first device in a targeted manner based on the request of the first device, thereby avoiding unnecessary transmission of the first sensing data and thus saving transmission resources.

[0421] In some possible embodiments, the method shown in Figure 11 may also include S1104 to S1105:

[0422] S1104: The first device can receive first information, and the first information can indicate a first sensing need.

[0428] The specific content of S1106 to S1107 can refer to S908 to S909, and will not be described here.

[0429] By the method shown in FIG. 11, the first device at the access network side can obtain the first sensing data, which is obtained by processing the sensing data of the at least one terminal according to the position of the at least one terminal. In the method, the access network side can not obtain the position of the at least one terminal. The actual position of the terminal belongs to the privacy of the terminal. Therefore, the method can realize the processing of the sensing data of the at least one terminal while ensuring the privacy of the at least one terminal.

[0430] In addition, in the method, the first device can be used for sensing, and the device used for communication at the access network side is independent of the first device, so that the scalability of the first device can be improved, and higher sensing requirements can be met by upgrading the first device.

The method shown in FIG. 16 or FIG. 17 is a possible example of the method shown in FIG. 9 and FIG. 11. In the method shown in FIG. 16 or FIG. 17, the first device can receive the first sensing data, which is obtained by processing the sensing data of the at least one terminal according to the position of the at least one terminal.

Optionally, in the method shown in FIG. 12, FIG. 14, and FIG. 16, the CU can directly communicate with the SU, or the CU can communicate with the SU through the DU.

[0433] In some implementations, in the method shown in FIG. 12, FIG. 14, and FIG. 16, the CU can be replaced by the DU. Optionally, the DU can directly communicate with the SU, or the DU can communicate with the SU through the CU.

[0434] In the method shown in FIG. 13, FIG. 15, and FIG. 17, the first device is taken as an example of NodeC, and the second device is taken as an example of NodeB.

[0435] As shown in FIG. 12, the method comprises:

[0440] The third request is used to request information of at least one terminal. The information of the at least one terminal can include an identifier of the at least one terminal. Optionally, the information of the at least one terminal further includes information indicating a location of the at least one terminal, or the information of the at least one terminal further indicates the location of the at least one terminal.

[0451] The specific content of step F1 can refer to the manner g2 in S907 above, and will not be repeated.

[0452] Optionally, before sending the second information, the SU can select a terminal for sensing. For example, the SU can select a terminal supporting sensing, the selection being based on, for example, the capability of the terminal. For example, the terminal can send information indicating the capability of the terminal to the SU through one or more of the RU, the DU and the CU; in the case where the information indicating the capability of the terminal indicates that the terminal supports sensing, the SU can select the terminal.

[0453] Step F2: the SU sends first indication information to the CU, the first indication information indicating whether there is a terminal participating in sensing.
