Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, and in particular to a terminal device selection method, an information sending method and related devices. BACKGROUND

[0002] Wireless communication and perception fusion is one of the key technologies of the 5th generation (5G) mobile communication, which can be widely applied in typical application scenarios such as intelligent transportation, intelligent low-altitude, and intelligent network. Wireless communication and perception fusion realizes unified design of communication function and perception function through signal joint design and hardware sharing. Perception in wireless communication and perception fusion can be understood as wireless perception technology based on a communication system. For example, a base station transmits a wireless signal to a target object and receives a reflected echo signal of the target object. The base station obtains corresponding perception measurement quantities by analyzing the echo signal. For example, the number, position, and moving speed of the target object, and identity recognition of the target object.

[0003] Currently, there are mainly two kinds of perception scenarios, specifically, a per-area perception scenario and a per-object perception scenario. The per-area perception scenario is introduced as follows. A perception network element can receive a perception request. The perception request includes area information or position information of a target perception area. The perception network element can select a corresponding terminal device, and the terminal device can jointly implement a perception process with a base station or other terminal devices.

[0004] For area perception services, the participation and assistance of terminal devices are required in some scenarios. However, how to select appropriate terminal devices to participate in the perception process is a problem worth considering. SUMMARY

[0005] The present application provides a terminal device selection method, an information sending method and related devices, which are used to realize that a perception network element or an access network device selects appropriate terminal devices to participate in a perception process based on first information, and improve perception accuracy.

[0006] The first aspect of the present application provides a terminal device selection method, which can be executed by a sensing network element or an access network device, or implemented by a component (for example, a processor, a chip, or a chip system or a chip module, etc.) corresponding to the sensing network element or the access network device respectively, or implemented by a logic module or software capable of implementing all or part of the functions of the sensing network element or the access network device, or implemented by a logic module or software capable of implementing all or part of the sensing network element or the access network device. The method comprises: the sensing network element or the access network device receives first information, the first information being used to indicate information of at least one candidate terminal device, the at least one candidate terminal device being a candidate terminal device used to execute a sensing process; and the sensing network element or the access network device selects at least one target terminal device according to the first information, the at least one target terminal device being used to execute the sensing process. Thus, the sensing network element or the access network device selects a suitable terminal device to participate in the sensing process based on the first information, and the sensing accuracy is improved. Optionally, the at least one candidate terminal device can also be described as: the at least one candidate terminal device is a terminal device that can be used to execute the sensing process; or the at least one candidate terminal device is a terminal device that is expected or desired to execute the sensing process.

[0007] Based on the first aspect, in a possible implementation, the method is applied to a sensing network element; and the sensing network element receives the first information, comprising: the sensing network element receives the first information from an access network device, a core network device, or a positioning network element; or the method is applied to an access network device; and the access network device receives the first information, comprising: the access network device receives the first information from a core network device or a positioning network element. Thus, the sensing network element or the access network device acquires the information of the at least one candidate terminal device.

[0008] Based on the first aspect, in a possible implementation, before the sensing network element or the access network device receives the first information, the method further comprises: the sensing network element or the access network device sends a first request, the first request being used to request information of a candidate terminal device used to execute the sensing process. Thus, the sensing network element or the access network device actively requests the information of the candidate terminal device, so as to select a suitable terminal device to participate in the sensing process, and improve the sensing performance and the sensing accuracy.

[0009] Based on the first aspect, in a possible implementation, the method is applied to a sensing network element, and the sensing network element sends the first request, comprising: the sensing network element sends the first request to an access network device, a core network device, or a positioning network element; or the method is applied to an access network device, and the access network device sends the first request, comprising: the access network device sends the first request to a core network device or a positioning network element. In this implementation, some possible schemes for the sensing network element or the access network device to request the information of the candidate terminal device are provided, and the implementation of the schemes is enriched.

[0010] The second aspect of the present application provides an information sending method, which can be executed by an access network device, a core network device or a positioning network element, or realized by a component (for example, a processor, a chip, or a chip system or a chip module, etc.) corresponding to the access network device, the core network device or the positioning network element respectively, or realized by a logic module or software capable of realizing all or part of the functions of the access network device, the core network device or the positioning network element, or realized by a logic module or software capable of realizing all or part of the access network device, the core network device or the positioning network element.

Thus, the sensing network element or the access network device is assisted to select a suitable terminal device to participate in the sensing process based on the first information, and the sensing accuracy is improved.

[0070] The embodiments of the present application provide a terminal device selection method, an information sending method and related devices, which are used to enable a perception network element or access network device to select a suitable terminal device based on first information to participate in the perception process, thereby improving perception accuracy.

[0071] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0072] The term "and / or" as used in this application can be used to describe an association relationship between related objects, indicating that three possible relationships exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0073] Wireless communication perception fusion is widely applicable in typical application scenarios such as smart transportation, smart low-altitude areas, and smart networks. Through joint signal design and hardware sharing, wireless communication perception fusion achieves unified design of communication and perception functions. The perception in wireless notification perception fusion can be understood as wireless perception technology based on the communication system. For example, a base station transmits a wireless signal to a target object and receives an echo signal reflected by the target object. The base station analyzes the echo signal to obtain corresponding perception measurements, such as the number, location, movement speed, and identity of target objects.

[0074] Currently, there are two main perception scenarios: area-based and target-based. Area-based perception involves sensing a specific area, such as low-altitude areas in cities, roads, and factories. Typical application scenarios include: locating and detecting drones intruding into regulatory areas at low altitudes in cities, thereby enabling drone intrusion detection in fixed areas; real-time detection of vehicle movement paths and speeds on urban roads to perceive the operating status of highways; sensing channel changes for breathing detection, fitness monitoring, gesture or posture recognition, etc.; and analyzing the relationship between signal attenuation in communication links and weather indicators to obtain corresponding weather indicators and perform weather detection. Target-based perception involves using synaesthesia technology to perceive and track targets with identification, enabling dynamic detection of targets.

[0075] The sensing methods mainly include base station side sensing, terminal device assisted sensing and terminal device side sensing, which can be divided into six sensing modes. Figures 1a to 1f Introducing the six perception modes.

The access network device receives the reflected signal and measures the reflected signal to obtain a sensing measurement result. The access network device can send the sensing measurement result to the sensing network element.

Figure 1dAs shown, the terminal device transmits a sensing reference signal. The sensing reference signal is reflected by a target object to generate a reflected signal. The access network device receives the reflected signal and measures the reflected signal to obtain a sensing measurement result.

Terminal device #2 receives the reflected signal and measures it to obtain a sensing measurement result. Terminal device #2 can report the sensing measurement result to the sensing network element.

[0082] This application applies to the above Figures 1c to 1f The terminal device shown in the figure participates in the perception scenario. Figures 1c to 1f These are just some example scenarios, and this application does not limit the scenarios in which terminal devices participate in perception. As long as the selection and perception of terminal devices are involved, they are all application scenarios applicable to this application, and this application does not make specific restrictions.

[0083] It should be noted that this application takes the problem of selecting terminal devices in the perception process as an example to introduce the technical solution of this application.

Optionally, the access network device realizes communication with the SF-U through the UPF 205, and realizes communication with the SF-C through the AMF 204. Figure 2 It should be noted that the above-mentioned communication system, the access network device can also be directly connected with the SF 206, that is, it does not need to realize communication with the SF 206 through the UPF 205 and the AMF 204. Optionally, the SF 206 belongs to the core network.

The SC 304 is connected to the access network device 302 and the access network device 303 through the interface respectively. The access network device 302 and the access network device 303 can also be connected to different SCs respectively. Optionally, the communication system further comprises a SF 305. When the communication system comprises S305, the SF 305 is connected to the SC 304. Figure 3 The SF 305 shown is an example of implementation without separation of user plane and control plane. In actual applications, the user plane and the control plane of the SF 305 can also be separated, for example, the SC 304 comprises SC-C and SC-U, and the SF 305 comprises SF-C and SF-U. Among them, the SC-C is connected to the SF-C, and the SC-U is connected to the SF-U; or only the SC-C and the SF-C are connected, which is not limited in the present application.

[0095] It should be noted that the above Figure 3 In the communication system shown, the SC 304 is directly connected to the SF 305, and the SC 304 can also be connected to the SF 305 through the UPF and the AMF, which is not limited in the present application. Optionally, the SC 304 belongs to the access network.

[0096] Figure 4 Another schematic diagram of the communication system of the embodiment of the present application is shown. As Figure 4As shown, the communication system includes terminal device 401, access network device 402, access network device 403, UPF 404, and AMF 405. The access network device 401 and the access network device 402 communicate through the Xn interface. The SC is deployed or integrated on the access network device 402. The access network device 402 is connected with the UPF 404 through the NG-U interface, and the access network device 402 is connected with the AMF 405 through the NG-C interface. The access network device 403 is connected with the UPF 404 through the NG-U interface, and the access network device 403 is connected with the AMF 405 through the NG-C interface. Optionally, the communication system further includes SF 406. The access network device 402 is connected with the SF 406 through the UPF 404 and the AMF 405.

[0097] Figure 4 The SF 406 shown is an example of a perception function in a user plane and a control plane separation implementation. In actual application, the user plane and the control plane of the SF 406 can also be separated, and the specific application is not limited.

[0098] It should be noted that when the access network device 402 adopts the separation architecture of CU and DU, the SC can be deployed or integrated on the CU or the DU, and the specific application is not limited.

[0099] It should be noted that the above Figures 2 to 4 The name of the SF involved in the communication system shown is not limited, for example, it can also be called a perception network element, a perception demand network element, a perception management network element, or a perception function entity, and the specific application is not limited. The above Figure 3 and Figure 4 The name of the SC involved in the communication system shown is not limited. For example, it can also be called a control network element, an edge perception function network element, an edge control network element, or an edge control node, and the specific application is not limited.

[0100] The SF can be a network element in the core network that provides perception-related functions. The functions of the SF include management of perception nodes, coordination of perception resources, processing of perception measurement quantities, opening of perception results, etc., that is, functions related to perception. The SC can be a network element in the access network that provides perception-related functions. The SC can have functions related to perception, for example, the SC receives perception demands from the SF; perception node management; coordination of perception resources within the region; processing of perception measurement results; or receiving perception requests from application function network elements, etc.

[0101] The technical solutions of the present application can be applied to a cellular communication system related to the 3rd generation partnership project (3GPP). For example, a fourth generation (4G) communication system, a fifth generation (5G) communication system, a communication system after the fifth generation communication system. For example, a sixth generation communication system. For example, the fourth generation communication system can include a long term evolution (LTE) communication system, an LTE frequency division duplex (FDD) system, or an LTE time division duplex (TDD) system. The fifth generation communication system can include a new radio (NR) communication system. The technical solutions of the present application can also be applied to a wireless fidelity (WiFi) system, a communication system supporting multiple wireless technology fusion, a device-to-device (D2D) system, an Internet of Things communication system, an industrial Internet communication system, a vehicle to everything (V2X) communication system, or a satellite communication system, etc.

[0102] The terminal device, the access network device, the core network device and the sensing network element related to the present application are introduced as follows.

[0103] A terminal device, also referred to as a user equipment (UE), a mobile station (MS), a mobile terminal (MT), a customer premise equipment (CPE), etc. A terminal device is a device that includes a wireless communication function (providing voice / data connectivity to a user). For example, a handheld device with wireless connectivity, in-vehicle device, machine type communication (MTC) terminal, etc. Currently, a terminal device can include a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, or a wireless terminal in smart home, etc. For example, a wireless terminal in self driving can be a drone, a helicopter, or an airplane, etc. For example, a wireless terminal in vehicle-to-everything (V2X) can be a vehicle-mounted device, a whole vehicle device, a vehicle-mounted module, a vehicle, or a ship, etc. A wireless terminal in industrial control can be a camera, a robot, or a mechanical arm, etc. A wireless terminal in smart home can be a television, an air conditioner, a sweeping machine, a sound box, or a set-top box, etc. A terminal device can also be a transport vehicle with a wireless communication function, a communication module, a road side unit (RSU) with terminal device function.

[0104] It should be noted that a terminal device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, a module, or a control unit in the above-mentioned devices or apparatus, and the specific application is not limited. For example, a chip can be a chip responsible for communication function in a terminal device, for example, 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.

[0105] An access network device is a device deployed in a wireless access network to provide wireless communication functions for terminal devices. The access network device can also be referred to as a radio access network (RAN) entity, an access node, a network node, a network device, or a communication apparatus, etc.

[0106] Specifically, the access network device can be an access network device for a 3rd generation partnership project (3GPP) related cellular system. For example, a fourth-generation (4G) mobile communication system, a 5G mobile communication system, or a 6G mobile communication system. The access network device can also be an access network device in an open RAN (O-RAN or ORAN) or a cloud radio access network (CRAN). Alternatively, the access network device can also be an access network device in a communication system obtained by fusing two or more of the above communication systems.

[0107] The access network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WiFi) system, a macro base station, a micro base station, a wireless relay node, a donor node, a wireless controller in a CRAN scenario, a wireless backhaul node, a transmission point (TP), or a transmission and receiving point (TRP). The access network device can also be an access network device in a 5G mobile communication system. For example, a next generation NodeB (gNB), a TRP, a TP, or one or a group (including multiple antenna panels) of antenna panels of a base station in a new radio (NR) system, or a base station in a 5G mobile communication system. Alternatively, the access network device can also be a network node constituting a gNB or a transmission point. For example, a centralized 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 arranged, or can be included in the same network element. For example, a BBU. The RU can be included in a radio frequency device or a radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the access network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, in a V2X technology, the access network device can be a road side unit (RSU).

[0108] It should be noted that the CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as an open centralized unit (O-CU) or an open CU, the DU can also be referred to as an open distributed unit (O-DU), the centralized unit control plane (CU-CP) can also be referred to as an open centralized unit control plane (O-CU-CP) or an open CU-CP, the centralized unit user plane (CU-UP) can also be referred to as an open centralized unit user plane (O-CU-UP) or an open CU-UP, and the RU can also be referred to as an open radio unit (O-RU). The specific application is not limited. Any one of the CU, CU-CP, CU-UP, DU and RU in the present application can be realized by a software module, a hardware module, or a combination of a software module and a hardware module.

[0109] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 as follows.

[0110] Table 1

[0111]

[0112] It should be noted that the access network device can be one network element or multiple network elements shown in Table 1 above, and the specific application is not limited.

[0113] It should be noted that Table 1 above is only an example. In actual applications, the protocol layer functions supported by each network element are not limited. For example, each network element can support more protocol layer functions, or the protocol layer functions supported by each network element can be configured in combination with the actual application. The specific application is not limited.

[0114] The architecture of the CU and the DU of the access network device will be introduced below. The access network device includes at least one CU and at least one DU. Optionally, the access network device also includes at least one RU.

[0115] The following is an example of an access network device including a CU and a DU. The CU has part of the function of the core network, and the CU can include a CU-CP and a CU-UP. The CU and the DU can be configured according to the protocol layer function of the wireless network they implement. For example, the CU is configured to implement the function of the PDCP layer and the protocol layer above (for example, the function of the RRC layer and / or the SDAP layer). The DU is configured to implement the function of the protocol layer below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the PHY layer). For another example, the CU is configured to implement the function of the PDCP layer and the protocol layer above (for example, the RRC layer and / or the SDAP layer), and the DU is configured to implement the function of the protocol layer below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0116] When the CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane function of the CU, and the CU-UP is used to implement the user plane function of the CU. For example, when the CU is configured to implement the function of the PDCP layer, the RRC layer and the SDAP layer, the CU-CP is used to implement the function of the RRC layer and the control plane function of the PDCP layer, and the CU-UP is used to implement the function of the SDAP layer and the user plane function of the PDCP layer.

[0117] The CU-CP can interact with a network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function can be an access and mobility function network element, such as an AMF in a 5G mobile communication system. The AMF is used to be responsible for mobility management in the mobile network, such as location update of the terminal device, registration network of the terminal device, handover of the terminal device, etc. The CU-UP can interact with a network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, a user function (user plane function, UPF) in a 5G mobile communication system, is used to be responsible for forwarding and receiving data in the terminal device.

[0118] The above configuration of the CU and the DU is only an example, and the CU and the DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have part of the processing function of the protocol layer. For example, part of the function of the RLC layer and the function of the protocol layer above the RLC layer are arranged in the CU, and the remaining function of the RLC layer and the function of the protocol layer below the RLC layer are arranged in the DU. For another example, the function of the CU or the DU can be divided according to the service type or other system requirements. For example, according to the delay, the function that needs to meet the delay requirement is arranged in the DU, and the function that does not need to meet the delay requirement is arranged in the CU.

[0119] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0120] It should be noted that the access network device can be the device or apparatus shown above, or it can be a component (for example, a chip), module, or unit in the device or apparatus shown above, and this application does not limit it specifically.

[0121] Optionally, the ORAN architecture also involves a RIC module. Figure 5 As shown, Figure 5 This is a schematic diagram of the application architecture involving the RIC module under the ORAN architecture. Figure 5 As shown, the communication system includes an RIC module, which is specifically divided into a near-realtime RIC (near-realtime RIC, near-RT RIC) module and a non-real-time RIC (non-real time RIC, Non-RT RIC) module. The near-real-time RIC module is used for model training and reasoning. For example, the near-real-time RIC module is used to train an artificial intelligence (AI) model and use the AI ​​model for reasoning. The near-real-time RIC module can also obtain information for training or reasoning the AI ​​model from the access network node (for example, CU, CU-CP, CU-UP, DU, and / or RU), and can also obtain information for training or reasoning the AI ​​model from the terminal device. Optionally, the near-real-time RIC module can transmit the results obtained by training or reasoning the AI ​​model to the access network node and / or the terminal device. Optionally, the results can be exchanged between the CU, DU, and RU. For example, the near-real-time RIC transmits the results to the DU, and the DU sends the results to the RU, thereby realizing near-real-time intelligent management of the access network.

[0122] The non-near real-time RIC module is configured to perform AI model training and inference. For example, the non-near real-time RIC module is configured to train an AI model and perform inference using the AI model. The non-near real-time RIC module can obtain data from the access network node (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or the terminal device, and perform AI model training or inference using the data as training data or inference data to obtain a corresponding result. Then, the non-near real-time RIC module delivers the result to the access network node and / or the terminal device. Optionally, the CU, DU, and / or RU can exchange the result. For example, the non-near real-time RIC module delivers the result to the DU, and the DU transmits the result to the RU.

[0123] It should be understood that the near real-time RIC module and the non-near real-time RIC module can be deployed as independent network elements or as part of other network devices. For example, the near real-time RIC module is deployed in the access network node. For example, the near real-time RIC module can be deployed in the CU and the DU, and the non-near real-time RIC module is deployed in the OAM, the cloud server, the core network device, or other network devices.

[0124] An example of a structure of an access network device including a CU and a DU is described below. Figure 6 An example of a structure of an access network device according to an embodiment of the present application is described below. For example, the access network device is a gNB. Please refer to Figure 6 In the 5G communication system, gNBs are connected through an Xn interface, and a gNB is connected to a 5th generation mobile communication technology core network (5GC) through an NG interface. As shown in Figure 6 gNB1 and gNB2 are connected through an Xn interface. gNB1 is connected to the 5GC through an NG interface 1, and gNB2 is connected to the 5GC through an NG interface 2.

[0125] A gNB can include a CU and a DU. That is, the functions of the base station are divided, and part of the functions of the base station are deployed in a gNB-CU, and the remaining functions are deployed in a gNB-DU. Multiple gNB-DUs share one gNB-CU, which can save costs and facilitate network expansion. For example, as shown in Figure 6 gNB1 includes a gNB-CU1, a gNB-DU1, and a gNB-DU2. The gNB-CU1 is connected to the gNB-DU1 through an F1 interface 1 and to the gNB-DU2 through an F1 interface 2. The structure of gNB2 is similar to that of gNB1, which will not be described one by one.

[0126] The above Figure 6Just as an example, one gNB-CU can connect one or more gNB-DU, which is not limited in the present application.

[0127] The split of gNB-CU and gNB-DU can be according to the protocol stack. For example, the RRC layer, the SDAP layer and the PDCP layer are respectively deployed in the gNB-CU corresponding to the protocol stack. The radio link control (RLC) layer, the MAC layer and the PHY layer are respectively deployed in the gNB-DU corresponding to the protocol stack. The gNB-CU and the gNB-DU are connected through the F1 interface. The above example is only for introducing the gNB-CU and the gNB-DU, and the protocol stack deployed in the gNB-CU and the gNB-DU is not limited in the present application.

[0128] In the present application, in the following scheme in which the access network device adopts the structure of CU and DU, the gNB-CU is referred to as CU, and the gNB-DU is referred to as DU.

[0129] It should be noted that the CU and the DU are an implementation manner in which the access network device is divided into network units, and the functions contained in the CU and the DU can be divided according to evolution or requirements, and the present application does not limit the functions contained in the CU and the DU. The names corresponding to the CU and the DU are also not limited in the present application.

[0130] The core network device can be responsible for access control, registration management, service management, mobility management and the like of terminal devices accessing the network. For example, the core network device is the access and mobility management function. In the present application, the names of the access and mobility management function can change with the evolution of the communication system. In the current communication system or the future communication system, as long as the function network element with other names similar to the function of the access and mobility management function, it can be understood as the access and mobility management function in the present application, and is applicable to the method provided in the present application.

[0131] The perception network element can obtain the information of the candidate terminal device, and select at least one target terminal device. Then, the perception network element can send a request to the access network device or the at least one target terminal device, so as to realize the perception process of terminal device assisted perception. Or, the perception network element can send a request to at least one terminal device to request the access network device to perform the perception process with the at least one target terminal device, so as to realize the perception process of terminal device side perception. In the present application, the perception network element in the following embodiments can be understood as the above Figures 2 to 4The SF or SC in the illustrated communication system. The name of the sensing network element can change as the communication system evolves. As long as other functional network elements with similar functions to the sensing network element are understood as the sensing network element of the present application. The name of the sensing network element is not limited. For example, the sensing network element can also be referred to as a sensing function network element, a first network element, a sensing function entity, a sensing measurement network element, or a sensing measurement entity. Hereinafter, the technical solutions of the present application are mainly introduced in the description of the sensing network element.

[0132] The technical solutions of the present application will be described below in conjunction with specific embodiments.

[0133] Figure 7 An embodiment of the terminal device selection method and information sending method of the present application is shown. Please refer to Figure 7 , the method comprises the following steps.

[0134] It should be noted that Figure 7 The embodiment shown takes the sensing network element, the access network device, the first terminal device and the second terminal device as the interactive execution subject for example to illustrate the method, but the present application does not limit the interactive execution subject. For example, Figure 7 The execution subject in steps 701a to 703, step 707, step 708, step 711, step 712, step 716, step 717, step 720, step 721, step 724 in the embodiment shown is the sensing network element, and the execution subject can also be a chip, a chip system or a processor supporting the sensing network element to implement the method, and can also be a logic module or software capable of implementing all or part of the functions of the sensing network element.

[0135] 701、The access network device sends first information to the sensing network element. Correspondingly, the sensing network element receives the first information from the access network device.

[0136] The first information is used to indicate information of at least one candidate terminal device. The at least one candidate terminal device is a candidate terminal device for performing a sensing procedure. Alternatively, the at least one candidate terminal device is a terminal device available for performing a sensing procedure. Alternatively, the at least one candidate terminal device is a desired or expected terminal device for performing a sensing procedure.

[0137] Optionally, the first information comprises at least one of the following: identification information of the at least one candidate terminal device, cell information where the at least one candidate terminal device is located, direction information, location information, motion information, connection state information, capability information, terminal type, or information about whether there is a LOS path or a NLOS path between the at least one candidate terminal device and the access network device.

[0138] Optionally, the identification information comprises a first identification of the at least one candidate terminal device. Optionally, the first identification of the at least one candidate terminal device is allocated by the access network device, the core network device, or the sensing network element.

[0139] Optionally, the first identification of the at least one candidate terminal device can be an identification allocated by the access network device. For example, a radio network temporary identity (RNTI), a RAN UE NGAP ID, or other identification allocated by the access network device for sensing, etc. For example, the RNTI can be a cell radio network temporary identifier (C-RNTI), or an inactive radio network temporary identifier (I-RNTI).

[0140] Optionally, the first identification of the at least one candidate terminal device can be allocated by the core network device. For example, a 5G S-temporary mobile subscription identifier (5G-S-TMSI), or an AMF UE NGAP ID. Optionally, the identification information of the at least one candidate terminal device further carries a gNB ID. Alternatively, the identification information of the at least one candidate terminal device further carries an AMF ID, or other identification allocated by the AMF for sensing, etc.

[0141] Optionally, the first identifier of the at least one candidate terminal device can be assigned by the perception network element, e.g., a perception procedure related identifier assigned by the perception network element. Optionally, the identifier information of the at least one candidate terminal device further carries an identifier of the perception network element.

[0142] Optionally, the first identifier of the at least one candidate terminal device can also be assigned by an application layer. For example, for V2X, proximity based services (ProSe), ranging and sidelink positioning, extended reality (XR), etc., the application layer assigns an application layer identifier for the at least one candidate terminal device. For example, the first identifier of the at least one candidate terminal device is a UE application layer identifier or a sidelink identifier of the at least one candidate terminal device.

[0143] Optionally, the cell information of the at least one candidate terminal device includes an identifier of a cell where the at least one candidate terminal device is located.

[0144] Optionally, the direction information includes at least one of the following: a reference signal index, a reference signal resource identifier, or an azimuth angle where the at least one candidate terminal device is located. The reference signal index or the reference signal resource identifier is used to indicate the direction where the at least one candidate terminal device is located. For example, the reference signal index is a synchronization signal / physical broadcast channel block (SSB) index. The reference signal resource identifier is a positioning reference signal (PRS) resource identifier or a channel state information reference signal (CSI-RS) resource identifier.

[0145] Optionally, the location information includes at least one of the following: an absolute coordinate position where the terminal device is located, or a relative coordinate position where the terminal device is located.

[0146] Optionally, the motion information includes at least one of the following: information about whether the at least one candidate terminal device is stationary, or motion trajectory information of the at least one candidate terminal device.

[0147] Optionally, the connection state information includes an RRC state of the at least one candidate terminal device. The RRC state is an RRC connected state, an RRC inactive state, or an RRC idle state.

[0148] Optionally, the terminal type comprises any one of the following: a vehicle-mounted device type or a handheld terminal type.

[0149] Optionally, the capability information comprises at least one of the following: whether at least one candidate terminal device supports a self-initiated self-receiving mode or a supported sensing mode.

[0150] Optionally, Figure 7 The illustrated embodiment also includes step 701a, which can be performed before step 701.

[0151] 701a. The sensing network element sends a first request to the access network device. Correspondingly, the access network device receives the first request from the sensing network element.

[0152] The first request is used to request information of a candidate terminal device for performing a sensing process. Alternatively, the first request is used to request information of a terminal device available for performing a sensing process. Alternatively, the first request is used to request information of a desired or expected terminal device for performing a sensing process.

[0153] Optionally, the first request comprises at least one of the following: sensing area information corresponding to the sensing process or a sensing identifier associated with the sensing process. For example, the sensing area information comprises at least one of the following: a coordinate range of the sensing area or a cell list. Thus, the location of the sensing area is represented by the cell list. For another example, the sensing process can be monitoring vehicles on a certain road or monitoring whether a drone has intruded into a certain sensing area. The application can define an associated identifier, i.e., a sensing identifier, for each sensing process. One sensing process corresponds to one sensing service request and one associated identifier, which can be used to indirectly indicate the sensing area corresponding to the sensing process. Thus, the access network device can select at least one candidate terminal device with a suitable location for the sensing process.

[0154] Optionally, Figure 7 The illustrated embodiment also includes step 702, which can be performed after step 701.

[0155] 702. The sensing network element selects at least one target terminal device according to the first information.

[0156] Optionally, the at least one target terminal device belongs to the at least one candidate terminal device.

[0157] For example, the first information includes location information of the at least one candidate terminal device. The perception network element selects a terminal device at a suitable location as the at least one target terminal device according to the location information of the at least one candidate terminal device. For another example, the first information includes whether there is a LOS path or a NLOS path between the at least one candidate terminal device and the access network device. The perception network element preferentially selects one or more terminal devices having a LOS path with the access network device as the at least one target terminal device. In the present application, the LOS path can be understood as a reflected echo signal of the perception reference signal in the propagation process only undergoing one reflection. For another example, the first information includes connection state information of the at least one candidate terminal device. The perception network element preferentially selects one or more terminal devices in an RRC connected state as the at least one target terminal device according to the first information. For another example, the first information includes motion information of the at least one candidate terminal device. The perception network element preferentially selects a stationary terminal device or a terminal device moving at a low speed as the at least one target terminal device according to the first information. For another example, the first information includes a terminal type of the at least one candidate terminal device. The perception network element preferentially selects a terminal device of a suitable terminal type as the at least one target terminal device according to the first information. For example, in a V2X scenario, the perception network element can preferentially select a terminal device of a vehicle type as the at least one target terminal device. For another example, the perception network element can select an RSU as the at least one target terminal device.

For example, the one or more propagation paths can comprise a first path, a strongest path, and / or a second strongest path between the access network device and the first terminal device.

[0175] Optionally, the first perception measurement result is point cloud data obtained by the first terminal device through the first perception reference signal.

[0201] Scenario three: The first terminal device performs the sensing procedure in a self-initiated and self-received mode. That is, the sensing network element selects the sensing mode of terminal device side sensing. For example, as shown in the sensing mode. Figure 1e

[0202] Some possible operation procedures in scenario three will be introduced below in steps 717 to 720. For scenario three, other operation procedures can also be used, which are not limited in the present application.

[0203] Optionally, Figure 7 As shown in the embodiment, the method further includes step 717, which can be performed after step 701.

[0204] 717、The sensing network element sends a fifth request to the first terminal device. Correspondingly, the first terminal device receives the fifth request from the sensing network element.

[0205] The fifth request is used to instruct to perform the sensing procedure. The first terminal device can be understood as a target terminal device selected by the sensing network element based on the first information. That is, the first terminal device is the at least one target terminal device. Optionally, the first terminal device is one of the at least one candidate terminal device. Optionally, the fifth request is also used to indicate a sensing mode used to perform the sensing procedure, for example, the fifth request indicates the sensing mode as shown in the above Figure 1e

[0206] Optionally, if Figure 7 ​​The illustrated embodiment also includes step 702, and step 717 can be performed after step 702.

[0207] 718. The first terminal device transmits a third sensing reference signal.

[0211] Scenario four: The first terminal device and the second terminal device perform a sensing process. The first terminal device is the transmitter of a fourth sensing reference signal, and the second terminal device is the receiver of the fourth sensing reference signal. That is, the sensing network element selects the sensing mode of terminal device side sensing. For example, as shown in the sensing mode. Figure 1f

[0212] Some possible operation processes in scenario four will be introduced below in combination with steps 721 to 724. For scenario four, other operation processes can also be used, and the specific application is not limited.

[0213] Optionally, Figure 7 The illustrated embodiment also includes step 721, and step 721 can be performed after step 701.

[0214] 721. The sensing network element transmits a sixth request to the first terminal device. Correspondingly, the first terminal device receives the sixth request from the sensing network element.

[0215] The sixth request is used to request to perform a sensing process. Optionally, the sixth request includes a second identifier of a second terminal device. The second identifier of the second terminal device is used to identify the second terminal device between the sensing network element and the second terminal device. For example, the second identifier of the second terminal device is a UE application layer identifier or a sidelink identifier of the second terminal device. Thus, the first terminal device and the second terminal device are instructed to perform a sensing process.

[0216] The first terminal device and the second terminal device can be understood as target terminal devices selected by the sensing network element based on the first information. That is, the first terminal device and the second terminal device are the at least one target terminal device. Optionally, the first terminal device and the second terminal device are two of the at least one candidate terminal device.

[0217] ​In a possible implementation, the first information includes a first identifier of the first terminal device and a first identifier of the second terminal device. The first identifier of the first terminal device is the same as the second identifier of the first terminal device, and the first identifier of the second terminal device is the same as the second identifier of the second terminal device. Therefore, the perception network element can send a sixth request to the first terminal device, where the sixth request carries the second identifier of the second terminal device. Thus, the first terminal device is instructed to perform the perception procedure with the second terminal device.

[0218] In another possible implementation, the first information includes a first identifier of the first terminal device and a first identifier of the second terminal device. The first identifier of the first terminal device is different from the second identifier of the first terminal device, and the first identifier of the second terminal device is different from the second identifier of the second terminal device. Therefore, if the perception network element selects the first terminal device and the second terminal device according to the first information, the perception network element can obtain the second identifier of the second terminal device. Then, the perception network element can send a sixth request to the first terminal device, where the sixth request carries the second identifier of the second terminal device. Optionally, the perception network element can request the second identifier of the second terminal device from the core network device or the gateway device. Alternatively, the second terminal device can actively report the second identifier of the second terminal device.

[0219] Optionally, Figure 7 The illustrated embodiment also includes steps 722 to 724, which can be executed after step 721.

[0220] 722. The first terminal device sends a fourth perception reference signal to the second terminal device. Correspondingly, the second terminal device receives the fourth perception reference signal from the first terminal device.

[0221] 723. The second terminal device measures the fourth perception reference signal to obtain a fourth perception measurement result.

[0222] The fourth perception measurement result is similar to the first perception measurement result, and details can be referred to the description of the first perception measurement result.

[0223] 724. The second terminal device sends the fourth perception measurement result to the perception network element. Correspondingly, the perception network element receives the fourth perception measurement result from the second terminal device.

[0224] Therefore, the sensing network element selects at least one target terminal device according to the first information. Thus, better execution of the sensing process is achieved, and sensing accuracy is improved. For example, if the sensing network element has no motion information of the terminal device and is unaware of the real-time channel condition of the air interface, the terminal device selected by the sensing network element can not be able to effectively perform the sensing task. For example, the position of the terminal device is not suitable, causing the terminal device to be unable to receive the sensing reference signal or the signal quality of the sensing reference signal received by the terminal device to be poor, which can result in low sensing accuracy. In the present application, the access network device provides the first information to the sensing network element, so that the sensing network element can select a suitable terminal device and enable different sensing modes, so that the sensing network element can select a suitable sensing mode according to the sensing task, thereby improving sensing performance.

[0225] In the present embodiment, the description of the identifier is exemplified by the sensing network element sending a request message to the access network device, and can also be applied to other messages exchanged between the sensing network element and the access network device.

[0226] It should be noted that, optionally, in the separation architecture of the CU and the DU, the above Figure 7 In the embodiment shown in the above

[0227] It should be noted that, in the embodiment shown in the above Figure 7 In the embodiment shown in the above, the sensing network element can be directly connected with the access network device, or can be connected with the access network device through the core network device. For the case that the sensing network element is connected with the access network device through the core network device, the sensing network element can first send a corresponding request to the core network device, and then the core network device sends a UE association message to the access network device using an NGAP interface. Alternatively, the sensing network element can first send a corresponding request to the core network device, and then the core network device sends the request to the first terminal device through a NAS layer message.

[0228] In the embodiment of the present application, the sensing network element receives the first information from the access network device, and the first information is used to indicate information of at least one candidate terminal device, which is a candidate terminal device for performing the sensing process. Then, the sensing network element selects at least one target terminal device according to the first information, and the at least one target terminal device is used to perform the sensing process. Thus, the sensing network element selects a suitable terminal device to participate in the sensing process based on the first information, and sensing accuracy is improved.
