Description

A sensing and measurement method, device, chip, and system

[0001] This application claims priority to Chinese Patent Application No. 202410524872.1, filed with the State Intellectual Property Office of China on April 28, 2024, entitled "A Sensing Measurement Method, Apparatus, Chip and System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of communication technology, specifically relating to a sensing and measurement method, device, chip, and system. Background Technology

[0003] Sensing services are one of the key services of 6G. In applications such as environmental imaging or reconstruction, signals transmitted by sensing devices (e.g., terminals or base stations) can be used to perceive the position or shape of surrounding objects through reflection, scattering, and diffraction on target objects as they propagate through space. Specifically, the base station or terminal measures information such as the time delay, Doppler effect, and angle of the multipath signal and reports the measurement results to the sensing network elements. Multipath signals correspond to signals reflected, scattered, and diffracted through reflection / scattering / diffraction points on the target object.

[0004] Typically, sensing devices can perform multiple sensing measurements on the same reflection point / scattering point / diffraction point on a target object, or on some key points of interest, and report them to the sensing network element. Alternatively, multiple sensing devices can perform sensing measurements on some key points on the target object to obtain multiple measurement results, and report them to the sensing network element.

[0005] For sensing network elements, they can improve sensing accuracy or resolution by fusing multiple measurement results or measurements of reflection / scattering / diffraction points observed at multiple times. However, in practice, the sensing network element cannot determine which measurement results can be fused or correlated. Therefore, how the sensing network element can identify the received multiple measurement results is a technical problem that urgently needs to be solved. Summary of the Invention

[0008] In the sensing measurement method provided in this application embodiment, the first device obtains a first measurement result corresponding to a point on the sensing target by measuring a first signal. Then, the first device sends a measurement report to the sensing network element. Since the reported measurement report includes not only the first measurement result but also first information, and the first information is used to identify the point on the sensing target, the receiving party (i.e., the sensing network element) can determine the identifier of the point on the sensing target corresponding to the first measurement result based on the first information in the measurement report after receiving the measurement report. This is beneficial for the sensing network element to perform association or fusion processing on multiple measurement results of the same point identifier on the sensing target.

[0087] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0088] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0089] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0090] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner to facilitate understanding.

[0091] It should be understood that in this application, "at least one (item)" means one or more. "More than one" means two or more. "At least two (items)" means two or three or more. "And / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural.

[0092] The character " / " generally indicates that the preceding and following objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any single or multiple items. For example, "at least one of a, b, or c" can be expressed as: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0093] Both "...when" and "if" indicate that a corresponding action will be taken under certain objective circumstances. They are not time limits, nor do they require a judgment action to be taken when the action is taken, nor do they imply any other limitations.

[0094] Before introducing the embodiments of this application, the relevant terms involved in this application are explained as follows:

[0095] Line-of-sight (LOS): A wireless transmission line where there are no obstructions along the straight line from the transmitter to the receiver.

[0096] Non-line-of-sight (NLOS): Wireless propagation occurs beyond the typical line-of-sight (LOS) between the transmitter and receiver, such as in ground reflections.

[0097] Virtual base station (VBS): A virtual base station that is spatially mirror-symmetric to the physical base station about the reflecting surface. For a reflection path occurring on the reflecting surface, the time delay of the reflection path is equivalent to the LOS path from the virtual base station to the terminal.

[0098] Figure 1 illustrates the terminal location process in wireless positioning services. As shown, the positioning network element (LMF) sends a location information request to the serving base station providing services to the terminal. This request requests the serving base station to locate the terminal's position. It is understood that this location information request includes the UE ID, which the serving base station uses to determine the terminal identified by the UE ID. Upon receiving the location information request, the serving base station sends a location information response to the LMF, configuring the Sounding Reference Signal (SRS) configuration information for the terminal. Subsequently, the Location Management Function (LMF) sends measurement requests to multiple transmission reception points (TRPs) (i.e., one or more neighboring base stations and the serving base station) to request them to measure the angle of arrival or time of arrival of the reference signal sent by the terminal. The terminal sends an uplink SRS signal based on the SRS configuration information sent by the serving base station, and each TRP reports its measurement results of the uplink SRS signal sent by the terminal to the LMF.

[0099] As mentioned above, in existing technologies, terminal positioning is based on the terminal's UE ID. The LMF can interact with the base station or UE to exchange positioning requests and measurement results based on the UE ID. Commonly used wireless positioning methods in NR cellular positioning mainly include downlink time difference of arrival (DL-TDOA), downlink angle of departure (DL-AOD), uplink time difference of arrival (UL-TDOA), uplink angle of arrival (UL-AOA), and multi-round trip time (multi-RTT).

[0100] DL-TDOA, UL-TDOA, and multi-RTT algorithms are time-of-arrival (TOA) based positioning technologies. This requires the receiver to measure the arrival time of the signal sent by the transmitter, convert it into distance information, and finally determine the location of the target. DL-AOD and UL-AOA are angle-based positioning technologies. The receiver measures the angle of arrival of a reference signal sent by the transmitter and then infers the receiver's location based on the angle information between the receiver and multiple transmitters at known locations. The following is a brief introduction to the positioning process using UL-TDOA technology as an example:

[0101] UL-TDOA positioning involves the UE sending an uplink SRS signal. Multiple transmission reception points (TRPs) receive the uplink SRS signal sent by the UE and send the time of arrival (TOA) of the SRS signal to the LMF. The LMF calculates the terminal location using a geometric solution method based on the TOA between each pair of TRPs and the known TRP locations.

[0102] Similar to UE ID, when a sensed target has an identifier, the sensed device (such as a base station or terminal) and the sensed network element can perform sensed measurements on the sensed target based on the identifier to obtain the measurement results.

[0103] For example, the identifier of the perceived target can be an identifier provided by the application, or an identifier temporarily assigned by the network.

[0104] Currently, for sensing services, such as environmental imaging or reconstruction applications, the position or shape of a target object (i.e., the sensing target) can be perceived by using reference signals sent by terminals or base stations as they propagate in space through reflection, scattering, and diffraction on the target object.

[0105] Specifically, base stations or terminals measure information such as time delay, Doppler, and angle of multipath signals and report the measurement results to the sensing network element. Multipath signals correspond to signals reflected / scattered / diffracted through reflection points / scattering points / diffraction points. Currently, for the same reflection point / scattering point / diffraction point, or for some key points of interest, the same sensing device can be used to measure the target object multiple times to obtain multiple sensing measurement results. Alternatively, multiple sensing devices (such as base stations) can be used to measure the target object from different perspectives to obtain multiple measurement results. To improve measurement accuracy, SF can fuse multiple measurement results of the same key point provided by different base stations or multiple measurement results provided by the same base station. As shown in Figure 2, terminal A and terminal B respectively send reference signals. The reference signals sent by terminal A and terminal B are reflected by key point A on the sensing target (reflection is used as an example here, but it could also be diffraction or scattering) and then received by base station A and base station B respectively. Then, base station A measures the reference signal sent by terminal A to obtain measurement result A and reports it to the sensing network element. Base station B measures the reference signal sent by terminal B and reports the measurement result B to the sensing network element. In this way, the sensing network element can obtain the measurement results of key points on the sensing target from different base stations from different perspectives.

[0106] While it's currently possible to perform sensing measurements based on the target's identifier, a sensing target typically has multiple points. Different sensing devices (such as base stations or terminals, or different terminals or base stations) can provide measurement results from different perspectives for the same point, or the same sensing device can provide measurement results at different times / locations for the same point. To improve sensing accuracy or resolution, sensing network elements need to fuse the measurement results of multiple measurements or observations of reflection / scattering / diffraction points at different times / locations. However, in practice, the measurement reports submitted by the sensing devices usually only carry the target's identifier. This makes it impossible for the sensing network elements to know which measurement results are suitable for fusion.

[0107] Based on this, the present application provides a sensing measurement method that can solve the technical problem in the prior art of how sensing network elements can identify which measurement results among multiple results can be fused.

[0108] The technical solution of this application can be applied to various communication systems, such as: Long Time Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, Public Land Mobile Network (PLMN) systems, Device to Device (D2D) network systems, Machine to Machine (M2M) network systems, and the 5th generation (5G) mobile communication technology systems, etc.

[0109] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0110] As shown in Figure 3, Figure 3 is an architecture diagram of a sensing system in a self-transmitting and self-receiving scenario provided by an embodiment of this application. As shown in Figure 3, the sensing system includes: a wireless access network device 100 and a sensing network element 200.

[0111] The wireless access network device 100 communicates with the sensing network element 200. For example, the wireless access network device 100 can send configuration information of sensing reference signal resources for transmitting reference signals to the sensing network element 200. The sensing network element 200 can send sensing signaling to the wireless access network device 100 to instruct the wireless access network device 100 to perform sensing measurements.

[0112] The wireless access network device 100 is used to transmit a reference signal on a sensing reference signal resource. This reference signal is transmitted through points on the sensing target and received by the access network device 100. For ease of understanding, the signal transmitted by the transmitting end through points on the sensing target is referred to as the first signal.

[0113] The wireless access network device 100 measures the received first signal to obtain a first measurement result corresponding to a point on the sensing target. Then, the wireless access network device 100 can report a measurement report to the sensing network element 200. This measurement report may include the first measurement result and first information, which indicates the identifier of the point on the sensing target. This facilitates the sensing network element 200 in determining the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0114] As shown in Figure 4, the sensing system in the self-transmitting and self-receiving scenario of the terminal provided in the embodiment of this application includes: terminal 300 and sensing network element 200.

[0115] The terminal 300 communicates with the sensing network element 200. For example, the terminal 300 can send configuration information of sensing reference signal resources for transmitting reference signals to the sensing network element 200. The sensing network element 200 can send sensing signaling to the terminal 300 to instruct the terminal 300 to perform sensing measurements.

[0116] The terminal 300 transmits a reference signal on the sensing reference signal resource. This reference signal is transmitted through points on the sensing target and received by the terminal 300. The terminal 300 then measures the received first signal to obtain a first measurement result corresponding to a point on the sensing target. Afterward, the terminal 300 can report a measurement report to the sensing network element 200. This measurement report may include the first measurement result and first information. The first information indicates the identifier of the point on the sensing target, thus facilitating the sensing network element 200 to determine the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0117] Optionally, the scenario in Figure 4 may also include a wireless access network device, which is used to allocate configuration information of sensing reference signal resources to the terminal 300.

[0118] It is understandable that the scenario architectures shown in Figures 3 and 4 are scenarios where the terminal / access network device transmits and receives signals on its own, that is, the reference signal sent by the terminal / access network device is reflected / diffracted / scattered by a point on the sensing target and then received by the terminal / access network device.

[0119] As shown in Figure 5, Figure 5 is an architecture diagram of another sensing system provided in an embodiment of this application. As shown in Figure 5, the sensing system includes: a terminal 300, a wireless access network device 100, and a sensing network element 200.

[0120] In one possible scenario, as shown in Figure 5(a), the radio access network device 100 communicates with the sensing network element 200. For example, the radio access network device 100 can send configuration information of sensing reference signal resources for the terminal 300 to transmit reference signals to the sensing network element 200. The sensing network element 200 can send sensing signaling to the terminal 300 to instruct the radio access network device 100 to perform sensing measurements.

[0121] For example, terminal 300 acts as a transmitter to send a reference signal, and wireless access network device 100 acts as a receiver to receive the first signal and measure it to obtain a first measurement result corresponding to a point on the sensing target. Afterward, wireless access network device 100 can report a measurement report to sensing network element 200. This measurement report may include the first measurement result and first information, which indicates the identifier of the point on the sensing target. This facilitates sensing network element 200 in determining the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0122] In another possible scenario, as shown in Figure 5(b), the terminal 300 communicates with the sensing network element 200. For example, the sensing network element 200 can send sensing signaling to the terminal 300 to instruct the terminal 300 to perform sensing measurements.

[0123] For example, terminal 300 acts as a receiver, and wireless access network device 100 acts as a transmitter. Specifically, wireless access network device 100 transmits a reference signal, and terminal 300, as the receiver, receives the first signal and performs measurements to obtain a first measurement result corresponding to a point on the sensing target. Afterward, terminal 300 can report a measurement report to sensing network element 200. This measurement report may include the first measurement result and first information. The first information indicates the identifier of the point on the sensing target, thus facilitating sensing network element 200 to determine the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0124] As shown in Figure 6, which is an architecture diagram of another sensing system provided in an embodiment of this application, the sensing system includes: wireless access network device 100, wireless access network device 400, and sensing network element 200.

[0125] In one possible scenario, as shown in Figure 6(a), the wireless access network device 400 and the sensing network element 200 can communicate with each other.

[0126] For example, wireless access network device 400 acts as a transmitter to send a reference signal, and wireless access network device 100 acts as a receiver to receive the first signal and perform measurements to obtain a first measurement result corresponding to a point on the sensing target. Afterwards, wireless access network device 100 can report a measurement report to sensing network element 200. This measurement report may include the first measurement result and first information, which indicates the identifier of the point on the sensing target. This facilitates sensing network element 200 in determining the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0127] In another possible scenario, as shown in Figure 6(b), the wireless access network device 100 and the sensing network element 200 can communicate. The wireless access network device 400 acts as a receiver, and the wireless access network device 100 acts as a transmitter. Specifically, the wireless access network device 100 transmits a reference signal, and the wireless access network device 400, as the receiver, receives the first signal transmitted through a point on the sensing target, and performs measurements to obtain a first measurement result corresponding to the point on the sensing target. Afterward, the wireless access network device 400 can report a measurement report to the sensing network element 200. This measurement report may include the first measurement result and first information, which indicates the identifier of the point on the sensing target. This facilitates the sensing network element 200 in determining the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0128] As shown in Figure 7, Figure 7 is an architecture diagram of a sensing system between different terminals provided in an embodiment of this application. As shown in Figure 7, the sensing system includes: terminal 300, terminal 500 and sensing network element 200.

[0129] In one possible scenario, as shown in Figure 7(a), terminal 500 acts as a transmitter to send a reference signal, and terminal 300 acts as a receiver to receive the reference signal transmitted through a point on the sensing target as a first signal, and performs measurements to obtain a first measurement result corresponding to the point on the sensing target. Afterwards, terminal 300 can report a measurement report to sensing network element 200. This measurement report may include the first measurement result and first information, which indicates the identifier of the point on the sensing target. This facilitates sensing network element 200 in determining the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0130] In another possible scenario, as shown in Figure 7(b), terminal 500 acts as a receiver and terminal 300 acts as a transmitter. Terminal 300 transmits a reference signal, and terminal 500, as the receiver, receives the first signal transmitted through a point on the sensing target, and performs measurements to obtain a first measurement result corresponding to that point on the sensing target. Afterward, terminal 500 can report a measurement report to sensing network element 200. This report may include the first measurement result and first information, which indicates the identifier of the point on the sensing target. This facilitates sensing network element 200 in determining the identifier of the point on the sensing target corresponding to the first measurement result based on the first information.

[0131] In the architecture shown in Figures 3 to 7, the sensing network element 300 is a device or component deployed in the core network or wireless access network to provide sensing functions for the network. It can also be called SMF (Sensing Management Function), or other names, which are not limited in this application embodiment.

[0132] Terminals can have sensing capabilities. For example, terminals include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication capabilities. A terminal can refer to user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. Terminals can also be cellular phones, cordless phones, session initiation protocol (SIP) phones, machine type communication (MTC) terminals, tags, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, in-vehicle devices, handheld devices, wearable devices, computing devices, portable devices, or in-vehicle devices, etc., as well as smartphones, smart glasses, terminal devices in 5G networks, or terminals in future evolved public land mobile networks (PLMNs), etc. This application embodiment does not limit these categories.

[0133] Furthermore, terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water (such as ships); and they can be deployed in the air (e.g., on airplanes, balloons, and satellites). Specifically, these terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, wireless terminals in self-driving vehicles, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. Terminal devices can also be communication chips with communication modules, vehicles with communication capabilities, or in-vehicle equipment (such as in-vehicle communication devices and chips).

[0134] Radio access network equipment: A device deployed in a radio access network that meets 4G standards and provides wireless communication functions for terminals, such as an evolved node B (eNB) in a long term evolution (LTE) system. eNBs can include various forms of macro base stations, micro base stations (also called small cells), relay stations, access points, wearable devices, and vehicle-mounted equipment. An eNB can also be a transmission and reception point (TRP).

[0135] Wireless access network equipment: A device deployed in a wireless access network that meets 5G standards and provides wireless communication functions for terminals, such as a next-generation base station (g nodeB, gNB). gNBs can include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, wearable devices, and vehicle-mounted equipment. gNBs can also be transmission and reception points (TRPs) or transmission measurement functions (TMFs). gNBs can include central units (CUs) and distributed units (DUs) integrated on them.

[0136] In addition, wireless access network equipment can also be a radio network controller (RNC), a radio controller in a cloud radio access network (CRAN) system, a base station controller (BSC), a home base station (e.g., home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), a mobile switching center, a base transceiver station (BTS) in a global system for mobile communication (GSM) or code division multiple access (CDMA) network, a node base station (NB) in a wideband code division multiple access (WCDMA) network, an evolved NB (eNB or eNodeB) in LTE, a base station in a future 5G network, or an access network device in a future evolved PLMN network, or a wearable device or vehicle-mounted device.

[0137] Figure 8A illustrates the overall system architecture of O-RAN. Compared to traditional RAN architecture, O-RAN can be understood as follows: RAN can be composed of a series of modules, such as antennas, radio remote units (RRUs), and building base band units (BBUs). Traditional RAN architecture does not concern itself with the transmission and communication between internal modules, only with the overall reception and output. Therefore, for traditional RAN equipment, all modules in the RAN come from the same manufacturer. O-RAN defines the architectural connections and standardized interfaces between the various modules within the RAN. Thus, a RAN can be decomposed into multiple modules. Because of the standardized interfaces, it can be assembled from modules from different equipment vendors. For example, for O-RAN, antennas from company A, RRUs from company B, and BBUs from company C can be purchased and finally assembled into a RAN device. Based on the O-RAN architecture diagram in Figure 8A and the ETSI TS103 859 protocol, the included network elements are described as follows:

[0138] Service Management and Orchestration Framework (SMO): Its function is similar to that of a network management system.

[0139] Non-Real Time RAN Intelligent Controller (Non-RT RIC): Used for non-real-time intelligent management of RAN functions. It enables AI / ML workflows including model training and updates, and guides applications / functions within the Near-RT RIC based on policies. The Non-RT RIC is located within the SMO module.

[0140] Near-Real-Time RAN Intelligent Controller (Near-RT RIC): Used to achieve near-real-time intelligent management of the RAN. Through data collection and related operations on the E2 interface, it enables near-real-time control and optimization of O-RAN modules and resources.

[0141] O-RAN Central Unit (O-CU): Used to implement the Radio Resource Control (RRC) layer, Packet Data Convergence Protocol (PDCP) layer, Service Data Adaptation Protocol (SDAP) layer, and other control functions in the 3GPP standard.

[0142] O-RAN Central Unit Control Plane (O-CU-CP): Similar to the CU-CP in the NR system, it is used to implement the functions of the RRC layer and the control plane functions of the PDCP layer. It is part of the O-CU.

[0143] O-RAN Central Unit User Plane (O-CU-UP): Similar to the CU-UP in the NR system, it is used to implement the functions of the SDAP layer and the user plane functions of the PDCP layer. It is part of the O-CU.

[0144] O-RAN Distributed Unit (O-DU): Based on low-layer function partitioning, it is used to implement the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and Higher Physical Layer (Higher PHY) layer in the 3GPP standard. The Higher Physical Layer functions include one or more of the following: Forward Error Correction (FEC) encoding / decoding, scrambling / descrambling, or modulation / demodulation.

[0145] The O-RAN Radio Unit (O-RU) is based on low-layer function partitioning and is used to implement the lower physical layer (Lower PHY) functions and radio frequency (RF) functions in the 3GPP standard. The lower physical layer functions include one or more of the following: Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (iFFT) transformation, digital beamforming, or extraction and filtering of the Physical Random Access Channel (PRACH). It is similar to the Transmission Reception Point (TRP) or Remote Radio Head (RRH) in 3GPP, but includes lower physical layer functions such as FFT / iFFT or PRACH extraction.

[0146] O-RAN Cloud (O-Cloud): As a cloud computing platform, it includes physical infrastructure nodes for hosting O-RAN functions such as RIC and O-DU; it supports software components (such as operating systems, virtual machine monitoring, container runtimes), management and orchestration functions.

[0147] Based on the O-RAN architecture diagram in Figure 8A and in accordance with the ETSI TS103 859 protocol, the included interfaces are described as follows:

[0148] A1 Interface: The interface between Non-RT RIC and Near-RT RIC, used for intelligent and dynamic control of radio resources within the O-RAN. Non-RT RIC provides policies, rich information, and ML model updates to Near-RT RIC through the A1 interface, while Near-RT RIC provides policy feedback to Non-RT RIC through the A1 interface.

[0149] E2 Interface: The E2 interface is an open interface between two endpoints used to connect the Near-RT RIC and the RAN node. RAN nodes include, for example, CU and DU in 5G, O-RAN compatible eNB in ​​4G, O-CU (O-CU-CP and / or O-CU-UP) in O-RAN, and / or O-DU, etc. The RIC can obtain data collection and feedback from the RAN node through the E2 node, and the RAN node can obtain control feedback from the Near-RT RIC through the E2 node.

[0150] O1 Interface: The interface between the management entity in the SMO and the O-RAN module, used for operation management. FCAPS management, software management, and file management are implemented through this interface.

[0151] O2 Interface: The interface between the SMO and the infrastructure management framework that supports O-RAN virtual network functionality.

[0152] The Open Fronthaul CUS-Plane interface includes the control plane (C-Plane), user plane (U-Plane), and synchronization plane (S-Plane). The control plane is used for real-time control between the O-DU and O-RU, such as transmitting beamforming weights from the O-DU to the O-RU or performing power control from the O-DU to the O-RU. The user plane is used to transmit communication data between the DU and RU for access network devices and terminals. The synchronization plane is used by the O-DU to provide clock synchronization for the O-RU.

[0153] Other 3GPP interfaces: (Refer to the 3GPP TS 38.401 protocol description).

[0154] NG interface: The interface between NR RAN equipment (such as base stations, CUs, CU-CPs, or CU-UPs) and the NR core network; among them, NG-u is the user plane NG interface, and NG-c is the control plane NG interface.

[0155] Xn interface: The interface between NR RAN devices (such as base stations, CUs, CU-CPs, or CU-UPs); where Xn-u is the user plane Xn interface and Xn-c is the control plane Xn interface.

[0156] X2 Interface: The interface between LTE RAN devices; X2-u is the user plane X2 interface, and X2-c is the control plane X2 interface. In NR, the X2 interface is mainly used in E-UTRA-NR dual connectivity (EN-DC) scenarios, where the master station is an LTE RAN device that connects to the LTE core network through the X2 interface.

[0157] E1 interface: The interface between CU-CP and CU-UP.

[0158] F1-C interface: The interface between CU-CP and DU.

[0159] F1-U interface: The interface between CU-UP and DU.

[0160] In the O-RAN architecture, a network element with sensing capabilities may be an RT RIC, where the O-DU performs multipath measurement and reports the measurement results to the RT RIC. A network element with sensing capabilities may also be an O-CU, which receives the multipath measurement results reported by the O-DU and performs sensing calculations.

[0161] As shown in Figure 8B, taking the communication system shown in Figures 3 to 7 as an example applicable to the 5G network architecture, in addition to the aforementioned sensing network elements, terminals, and radio access network equipment, the 5G network architecture may also include: access and mobility management function (AMF) network elements, application function (AF) network elements, network exposure function (NEF) network elements, network data analysis function (NWDAF) network elements, unified data management (UDM) network elements, policy control function (PCF) network elements, data network (DN), and location management function (LMF) network elements.

[0162] In this architecture, the SF can reuse the interfaces between the LMF and 5GC (5G Core Network) elements such as AMF (Access and Mobility Management Function), NEF (Network Exposure Function), UDM (Unified Data Management), NWDAF (Network Data Analytics Function), and PCF (Policy Control Function) for perception interaction. Perception control signaling between the LMF (including the SF) and RAN (Radio Access Network) or UE is transmitted through the AMF. Perception measurement data acquired by the RAN / UE can be transmitted to the LMF (including the SF) via the control plane, using the reused LPP (LTE Positioning Protocol) or NRPPa (NR Positioning Protocol Annex), or it can be transmitted via the user plane, using UPF (User Plane Function) for forwarding or direct transmission to the LMF (including the SF).

[0163] The newly added SF network element in this architecture can be deployed independently or co-located with 5GC network elements (such as AMF or LMF) according to sensing requirements. This network element can realize basic sensing functions, such as sensing authorization, sensing control, sensing measurement data processing, and result output. If the sensing function is co-located with the LMF, the LMF and GMLC (Gateway Mobile Location Center) need to be functionally enhanced to support the basic sensing functions. The GMLC is the first network element in the operator's network to process sensing requests, performing privacy checks or authorization functions, routing sensing requests to the AMF, and selecting the LMF, etc.

[0164] The sensing network element sets up interfaces and interacts with 5GC network elements such as AMF, NEF, UDM, NWDAF, PCF, LMF, and UPF. The specific interface definitions are as follows:

[0165] NS1 Interface: A new interface between sensing network elements and the AMF (Awareness and Detection Function). The NS1 interface can transmit sensing control signaling; for scenarios where sensing measurement data is uploaded from the control plane, this interface can also transmit sensing measurement data.

[0166] NS2 Interface: A new interface between the sensing network element and NEF. The NS2 interface can transmit signaling messages between the sensing network element and the service-side application function (AF) relayed through NEF, and at the same time open the sensing results to the AF.

[0167] NS3 interface: A new interface between the sensing network element and the UDM. Authentication or authorization can be achieved through the NS3 interface, and the terminal's sensing subscription information, service AMF information or other information can be obtained.

[0168] NS4 Interface: A new interface between the sensing network element and the NWDAF. Through the NS4 interface, the sensing network element and the NWDAF can jointly complete artificial intelligence (AI) processing related to sensing services.

[0169] NS5 Interface: A new interface between the sensing network element and the PCF. Through the NS5 interface, the sensing network element can transmit information such as the sensing requirements, QoS requirements or sensing results of the sensing service to the PCF, and the PCF will make decisions to generate PCC policies related to the sensing service.

[0170] NS6 Interface: A new NS6 interface is added between the sensing network element and the LMF. Through the NS6 interface, the sensing network element can obtain location-related information, such as the sensing area, the RAN information of the sensing target, and the location information of the sensed UE.

[0171] NS7 Interface: A new interface for the sensing network element and the user plane function. Sensing measurement data can be directly transmitted from (R)AN to the sensing network element via the user plane function, or it can be indirectly forwarded to the sensing network element via UPF. If the sensing is performed by (R)AN and forwarded via UPF, the UPF needs to be modified to support data transmission at the (R)AN granularity.

[0172] In addition to the newly added interfaces mentioned above, existing interfaces (such as N1, N2, N5, N8, N33, etc.) must support the transmission of information related to sensing services, such as authentication information, sensing service type, sensing service quality requirements, sensing measurement data, and sensing results.

[0173] If the sensing function is shared with the LMF, a new interface needs to be added between the LMF and GMLC to transmit sensing service-related information. Interfaces related to the LMF and GMLC (such as the NL1 interface between AMF and LMF, the NL2 interface between AMF and GMLC, the NL5 interface between NEF and GMLC, and the NL6 interface between UDM and GMLC) also need to support the transmission of sensing service-related information. A new NL9 interface needs to be added between the LMF and GMLC. Specific details are as follows:

[0174] N33 Interface: This is the interface between AF and NEF. Through this interface, the sensing service type, service requirements, sensing results, etc. can be transmitted.

[0175] NL5 interface: This is the interface between NEF and GMLC. Information such as sensing service type, service requirements, and sensing results can be transmitted through this interface.

[0176] NL6 interface: This is the interface between GMLC and UDM, through which privacy inspection data can be transmitted;

[0177] NL2 interface: This is the interface between NEF and AMF. Through this interface, information such as the type of sensing service, service requirements, and sensing results can be transmitted.

[0178] NL1 interface: This is the interface between AMF and LMF. Information such as the type of sensing service, service requirements, and sensing results can be transmitted through this interface.

[0179] The new interface NL9 is the interface between GMLC and LMF. Through this interface, the sensing service type, service requirements, sensing results, etc. can be transmitted.

[0180] As shown in Figure 8C, which is another network deployment architecture, the sensing network element is relatively independent from the 5G core network (5G Core, 5GC).

[0181] In the architecture shown in Figure 8C, the Sensing Function (SF) requires little or no interaction with the 5GC. For scenarios where sensing needs exist only within a specific area, this architecture can provide sensing services without requiring 5GC control or only requiring partial network element participation. Furthermore, localized deployment of the sensing network element ensures that sensing measurement data or results do not leave the campus, thus meeting enterprise requirements for the security and privacy of sensing measurement data or results, and reducing sensing latency. This architecture is simple, flexible, efficient, has few transmission nodes, is easy to deploy, and can optionally support terminal-related sensing needs, with implementation schemes for authorization, mobility management, and billing functions considered on demand.

[0182] In this architecture, the sensing network elements directly connect to the RAN nodes, and both sensing control plane signaling messages and sensing measurement data are transmitted via interface NS1. When a terminal participates in sensing, the control plane signaling messages are forwarded to the SF through the AMF, and the sensing measurement data is transmitted via NS1. In addition, the SF may also have interfaces with the 5GC network elements AMF, NEF, or NWDAF to ensure that the AF must provide sensing service requirements to the SF through core network functions.

[0183] For example, the NS1 interface: the interface between the sensing network element and the (R)AN, the NS1 interface is used to transmit sensing control signaling or sensing measurement data; in one deployment implementation, the sensing function can also be deployed at the base station;

[0184] NS2 interface: The interface between the sensing network element and the AMF. The NS2 interface is used to receive sensing service requests from the terminal or to transmit signaling messages between the sensing network element and other network elements in the core network, such as interaction messages with the UDM.

[0185] NS3 Interface: The interface between the sensing network element and NEF. The NS3 interface is used to transmit signaling messages between the sensing network element and the service-side AF via NEF, and at the same time, it exposes the sensing results to the AF. The interaction between the sensing function and the AF may not go through NEF.

[0186] In actual deployment, either the NS2 interface or the NS3 interface can be deployed. That is, the AF sends sensing service requests to the SF indirectly or directly to the SF (without NEF) through the NS2 (NEF) interface; or, the AF sends sensing service requests to the SF through the NS3 (NEF) interface and the NS2 (AMF) interface.

[0187] NS4 Interface: The interface between the sensing network element and the NWDAF. Through this NS4 interface, the sensing network element and the NWDAF jointly perform intelligent analysis and prediction to generate sensing results.

[0188] Figure 9 illustrates a scenario where a UE assists a base station in object perception. Taking the base station's coordinates as (x, y), two terminals with known locations (e.g., UE1 and UE2) participate in perceiving a target object. UE1 is located at (x1, y1), and UE2 is located at (x2, y2). UE1 and UE2 each send perception signals, which are reflected, scattered, or diffracted by the target object to reach the base station. Figure 9 uses reflection as an example, with the reflection point represented as (x0, y0). Furthermore, each UE's perception signal also has a direct path to the base station. Where d... UE1,BS and d UE2,BS d represents the distances of the direct paths from UE1 and UE2 to the base station, respectively. UE1,S +d BS,S and d UE2,S +d BS,S Let α0-α1 and α0-α2 represent the distances from UE1 to UE2 reflected by the sensing target to the base station, respectively. Let α0-α1 and α0-α2 represent the angles between the reflected distances from UE1 to UE2 reflected by the sensing target to the base station and their respective direct paths. The base station can obtain d using ranging technology. UE1,BS and d UE2,BS and d UE1,S +d BS,S and d UE2,S +dBS,S Alternatively, calculate the distance difference Δd1 = d between the reflected path and the direct path. UE1,S +d BS,S -d UE1,BS Δd2=d UE2,S +d BS,S -d UE2,BS The angle α0-α1 between the reflection path and the direct path is obtained through angle estimation techniques. 和 α0-α2. According to the Law of Cosines, we have (d UE1,BS +Δd1-d BS,S ) 2 =d 2 BS,S +d 2 UE1,BS -2d BS,S d UE1,BS cos(α0-α1),

[0189] Or, (d) UE2,BS +Δd2-d BS,S ) 2 =d 2 BS,S +d 2 UE2,BS -2d BS,S d UE2,BS cos(α0-α2) then according to the measured quantity d UE1,BS、 Δd1, α0-α1, can be used to calculate d BS,S ,

[0190] Alternatively, based on the measured quantity d UE2,BS Δd1, α0-α2, can be used to calculate d BS,S , Furthermore, the location of the reflection point (x0, y0) can be obtained by solving the following equation: (x-x0) 2 +(y-y0) 2 =d 2 BS,S (x1-x0) 2 +(y1-y0) 2 =(d 2 UE1,BS +Δd1-d BS,S ) 2 (x2-x0) 2 +(y2-y0) 2 =(d 2 UE2,BS +Δd2-d BS,S ) 2

[0191] The sensing signal sent by the terminal is reflected from the sensing target and reaches the base station. The reflection / scattering / diffraction points of the sensing signal on the object differ depending on the terminal's location. Therefore, the base station can measure reference signals sent by different terminals or the same terminal at different times / locations to obtain measurement results. The base station reports the measurement results to the sensing network element (SF), which can then calculate the positions of the different reflection points. Multiple reflection points can simulate the approximate position or shape of the sensing target object.

[0192] Alternatively, the terminal can send multiple reference signals to the base station from the same location. The base station measures the multipath signals transmitted through points on the sensing target by these multiple reference signals, obtaining multiple measurement results for the same reflection point. The base station reports these multiple measurement results to the sensing network element (SF) for this same reflection point. The sensing network element (SF) can then fuse these multiple measurement results to calculate the location of the reflection point, improving sensing accuracy.

[0193] It should be noted that the above is only an example of a reflection point. A reflection point can also be replaced by a scattering point or a diffraction point; the technical principle is the same. Hereafter, "point" will be used to represent the point. Furthermore, the above is only an example of a UE transmitting a reference signal and a base station receiving a reference signal. Other sensing methods are also possible, such as a base station transmitting a reference signal and a UE receiving a reference signal, a base station transmitting and receiving its own reference signal, base station A transmitting a reference signal and base station B receiving a reference signal, a UE transmitting and receiving its own reference signal, and UE-A transmitting a reference signal and UE-B receiving a reference signal. The technical principle is the same. In actual sensing implementation, one or more of the above six sensing methods can be used in combination, depending on the different sensing scenarios, sensing environments, and sensing service requirements.

[0194] In this application embodiment, the specific structure of the execution entity of the sensing and measurement method is not particularly limited, as long as it can communicate according to the sensing and measurement method of this application embodiment by running a program that records the code of the sensing and measurement method of this application embodiment. For example, the execution entity of the sensing and measurement method provided in this application embodiment can be a functional module in the first device that can call and execute the program, or it can be a communication device applied in the first device, such as a chip, chip system, integrated circuit, etc. These chips, chip systems, and integrated circuits can be disposed inside the first device or can be independent of the first device, and this application embodiment does not impose any restrictions.

[0195] As shown in Figure 10, Figure 10 illustrates a sensing measurement method provided in an embodiment of this application. The method includes:

[0196] Step 1001: The first device measures the first signal and obtains the first measurement result.

[0197] For example, the first signal is the transmission signal of the reference signal through a point on the sensing target, and the first measurement result corresponds to a point on the sensing target.

[0198] As an example, the reference signal can be sent by the first device, that is, the first device sends the reference signal itself, and then the reference signal sent by the first device is transmitted after passing through the point on the sensing target, is received by the first device and measured to obtain the first measurement result.

[0199] For example, the reference signal can be sent by a second device. In this scenario, the reference signal sent by the second device is transmitted after passing through a point on the sensing target, and is received and measured by the first device to obtain the first measurement result.

[0200] As an example, a point on a sensing target can refer to a reflection point, scattering point, or diffraction point on the sensing target.

[0201] For example, referring to Figure 3, the first device can be a wireless access network device 100. Or referring to Figure 4, the first device can be a terminal 300. For example, referring to Figure 5, the first device can be a wireless access network device 100, and the second device can be a terminal 300. Or referring to Figure 5, the first device can be a terminal 300, and the second device can be a wireless access network device 100.

[0202] For example, referring to Figure 6, the first device can be one of the wireless access network device 100 and the wireless access network device 400, while the second device can be the other of the wireless access network device 400 and the wireless access network device 100.

[0203] For example, referring to Figure 7, the first device can be one of the terminals 300 and 500, while the second device can be the other terminal of the terminals 300 and 500.

[0204] For example, taking a reflection point as an example, the sensing reference signal sent by the second device / first device is reflected after passing through the reflection point on the sensing target and then received by the first device. For example, taking a scattering point as an example, the sensing reference signal sent by the second device / first device is scattered after passing through the scattering point on the sensing target and then received by the first device. For example, taking a diffraction point as an example, the sensing reference signal sent by the second device / first device is diffracted after passing through the scattering point on the sensing target and then received by the first device.

[0205] As an example, the second device / first device may transmit a reference signal on the sensing reference signal resource according to the sensing reference signal resource configuration.

[0206] For example, the sensing reference signal resource configuration is used to indicate the time-frequency location and / or transmission period of the sensing reference signal resource. This sensing reference signal resource configuration may be pre-configured / specifically configured for the second / first device to transmit sensing reference signals.

[0207] Understandably, in a self-transmitting and self-receiving scenario, the first signal can also be called the echo signal.

[0208] Step 1002: The first device sends a measurement report to the sensing network element, and the sensing network element receives the measurement report from the first device.

[0209] For example, a measurement report includes a first measurement result and first information, which is used to identify points on the perceived target.

[0210] For example, the sensing target may have one or more points. After the reference signal is transmitted to the first device through the points on the sensing target, the first device can calculate the coordinates of the points that the reference signal passes through on the sensing target based on the scheme shown in Figure 9, and then determine the position of the point on the sensing target based on the coordinates of the point, and then determine the identifier of the point.

[0211] Step 1003: The sensing network element processes the first measurement result of the point on the sensing target based on the first information.

[0212] In the sensing measurement method provided in this application embodiment, a first measurement result corresponding to a point on the sensing target can be obtained by measuring the first signal propagated from the first device reference signal through a point on the sensing target. Then, the first device reports a measurement report to the sensing network element. Since the measurement report includes the first measurement result and first information for identifying the point on the sensing target, the sensing network element can determine the identifier of the point on the sensing target corresponding to the first measurement result based on the first information. Thus, multiple measurement results with the same point identifier can be associated or fused in subsequent processes.

[0213] In one possible embodiment of this application, the sensing network element further acquires at least one second measurement report, each second measurement report including a second measurement result and first information. The first information is used to indicate the identifier of a point on the sensing target corresponding to the second measurement result. Accordingly, step 1003 can be implemented in the following way:

[0214] Based on the first information, the sensing network element associates or fuses the measurement results from at least one second measurement report that correspond to the same point identifier as the first measurement result.

[0215] For example, the first information in the measurement report indicates that the first measurement result corresponds to the identifier of a point on the sensing target as reflection point 1, and the sensing network element also acquires multiple second measurement reports. For example, measurement report A and measurement report B, where the first information in measurement report A indicates that the second measurement result corresponds to the identifier of a point on the sensing target as scattering point 2. The first information in measurement report B indicates that the second measurement result corresponds to the identifier of a point on the sensing target as reflection point 1. Since the second measurement result and the first measurement result in measurement report B both correspond to the same identifier on the sensing target, namely reflection point 1, the sensing network element can associate or fuse the first measurement result and the second measurement result in measurement report B to calculate the position of reflection point 1.

[0216] Another example is that the sensing target may include multiple points, each with a point identifier, and different points correspond to different point identifiers. The multiple points include reflection point A and reflection point B. Then the first device can use the first information to indicate that the point identifier on the sensing target is reflection point A. This makes it easier for the sensing network element to determine that the point identifier on the sensing target corresponding to the first measurement result is reflection point A.

[0217] In one possible embodiment of this application, the first information indication includes: a first-level identifier and a second-level identifier, wherein points on the sensing target are identified by the first-level identifier and the second-level identifier. Thus, the sensing network element can not only determine the identifier of the sensing target corresponding to the first measurement result based on the first-level identifier (i.e., which sensing target the first device senses), but also determine the identifier of the points on the sensing target corresponding to the first measurement result based on the first-level identifier and the second-level identifier.

[0218] For example, the perceived target is identified by the first-level identifier (i.e., the first-level identifier is the identifier of the perceived target), or the first-level identifier and the identifier of the perceived target have a corresponding relationship.

[0219] For example, the second-level identifier corresponds to the identifier of the reflection point / scattering point / diffraction point. The second-level identifier can be either the identifier of a reflection point / scattering point / diffraction point, or it can have a corresponding relationship with the identifier of a reflection point / scattering point / diffraction point. This facilitates the identification of points on the sensing target by the sensing network element. By carrying the first-level and second-level identifiers in the measurement report, the receiver, i.e., the sensing network element, can determine which sensing target the measurement report belongs to based on the first-level identifier, and determine the identifier of the point on the sensing target corresponding to the first measurement result based on the first-level and second-level identifiers.

[0220] In this embodiment, by utilizing first information indicating / including: a first-level identifier and a second-level identifier, the SF can determine the identifier of the sensing target and the identifier of the point on the sensing target corresponding to the first measurement result. This is beneficial for sensing network elements to distinguish sensing targets in scenarios with multiple sensing targets. Furthermore, this application combines the first-level identifier and the second-level identifier to jointly identify the points on the sensing target. When the identifiers of points on multiple sensing targets are the same, it is beneficial for the SF to combine the first-level identifier to determine the sensing target corresponding to the point identified by the second-level identifier.

[0221] It is understandable that a sensing target can typically include multiple points, such as multiple reflection points, multiple diffraction points, or multiple scattering points, or multiple points can include one or more of the following: at least one reflection point, at least one diffraction point, and at least one scattering point. Therefore, in order for the sensing network element to clearly identify which point on the sensing target the first measurement result reported corresponds to, each point on the sensing target can have an identifier, so that the first device can add the identifier of that point as a second-level identifier in the measurement report.

[0222] For example, the sensing target includes a scattering point A and a reflection point B. Scattering point A and reflection point B each have a second-level identifier. If a reference signal sent by a first device or a second device is reflected by reflection point B on the sensing target, and then the first device receives the first signal reflected by reflection point B, the first device can measure the first signal and obtain a first measurement result. Subsequently, the first device can include the first-level identifier, the second-level identifier, and the first measurement result in its measurement report.

[0223] In one possible embodiment of this application, the method provided in this application may further include, before step 1201: the sensing network element sending information about a sensing target to the first device. Correspondingly, the first device receives the sensing target information from the sensing network element. The sensing target information includes at least an identifier of the sensing target. By receiving the sensing target information, the first device can easily determine which sensing target is being sensed and measured.

[0224] In one possible embodiment of this application, the method provided in this application further includes, before step 1201: the sensing network element sends information about its sensing target and second information to the first device. Accordingly, the first device receives the sensing target information and the second information from the sensing network element. The sensing target information includes at least an identifier of the sensing target, and the second information is used to indicate the identifiers of one or more points on the sensing target. Accordingly, the first device determines the identifiers of the points on the sensing target based on the second information.

[0225] As an example, the second information includes the identification of one or more points on the perceived target, or includes the range of identification or the set of identifications;

[0226] Accordingly, the second-level identifier is one of the identifiers of one or more points, or the second-level identifier is one of the identifiers within the identifier range or identifier set indicated by the sensing network element.

[0227] In one possible implementation of this application, the second information is used to indicate the identifiers of multiple points on the sensing target. For example, the second information includes the identifiers of multiple points on the sensing target or the second information includes the identifier range. Accordingly, the method provided in the embodiments of this application may further include: a first device determining the identifiers of the points on the sensing target from the identifiers of the multiple points.

[0228] In one possible implementation of this application, the first information indicates the identifiers of one or more boundary points of the sensing target and the identifiers of points on the sensing target. Alternatively, the first information identifies or indicates one or more boundary points of the sensing target and points on the sensing target.

[0229] In one possible implementation of this application, the method provided in this embodiment further includes: a sensing network element sending sensing target information to a first device; correspondingly, the first device receiving the sensing target information from the sensing network element; the sensing target information indicating the identifiers of one or more boundary points of the sensing target. The identifiers of the one or more boundary points are used to indicate the sensing target.

[0230] For example, the identifier of one or more boundary points includes any one or more of the following: the coordinates of one or more boundary points, or the latitude and longitude information of one or more said boundary points, or the angle information of one or more said boundary points relative to a reference point on the sensing target, or the distance information of one or more boundary points relative to a reference point on the sensing target.

[0231] As an example, the first device is a wireless access network device, which includes a distributed unit (DU) and a central unit (CU). The first device measures a first signal and obtains a first measurement result, including: the DU measuring the first signal, obtaining the first measurement result, and sending a first measurement report to the CU, the first measurement report including the first measurement result; the first device sends a measurement report to a sensing network element, including: the CU sending the measurement report to the sensing network element based on the first measurement report.

[0232] As an example, the first measurement report may include first information in addition to the first measurement result. As an example, after receiving the first measurement report, the CU may directly send the first measurement report as a measurement report to the sensing network element. Or, as another example, after receiving the first measurement report, the CU may process the first measurement report and then send the processed measurement report to the sensing network element.

[0233] As an example, the sensing network element is deployed on the radio access network (RAN) side or in the core network.

[0234] The following will describe the specific process of a perception measurement method provided in the embodiments of this application in different scenarios.

[0235] As shown in Figure 11, Figure 11 illustrates the specific flow of the sensing measurement method provided in this application embodiment, taking the terminal transmitting a reference signal gNB receiving a reference signal as an example. The method includes:

[0236] Step 1101: The sensing network element SF interacts with the gNB or terminal to exchange sensing capability information, and identifies whether the gNB or terminal has sensing capability based on the sensing capability information.

[0237] It is understandable that when the terminal or gNB has sensing capability, the sensing network element SF performs the following step 1302. When the sensing network element SF does not have sensing capability, the following steps 1102 to 1108 are omitted.

[0238] As an example, step 1101 can be implemented as follows: The sensing network element (SF) sends a request message to the gNB or terminal, which requests the gNB or terminal to report whether it has sensing capabilities, or the request message queries whether the gNB or terminal has sensing capabilities. The gNB or terminal responds to the request message by sending a response message to the sensing network element (SF), which includes indication information about whether the gNB or terminal has sensing capabilities. This allows the sensing network element (SF) to determine whether the gNB or terminal has sensing capabilities based on the indication information.

[0239] Step 1102: The sensing network element (SF) sends a sensing request signaling to the gNB. Correspondingly, the gNB receives the sensing request signaling from the sensing network element (SF).

[0240] For example, the perception request signaling is used to request the gNB to configure perception reference signal resources for the terminal or to request the gNB to report the terminal's perception reference signal configuration information.

[0241] For example, the perception request signaling includes a first field, which is used to instruct the gNB to configure perception reference signal resources for the terminal or to request the gNB to report the perception reference signal configuration information of the target terminal.

[0242] Step 1103: The gNB configures sensing reference signal resources or a set of sensing reference signal resources for the terminal. Correspondingly, the terminal receives the sensing reference signal resources or set of sensing reference signal resources configured by the gNB.

[0243] For example, the reference signal can be a channel sounding reference signal (SRS) or a dedicated sensing reference signal.

[0244] Step 1104: The gNB sends a sensing request response to the sensing network element SF. Correspondingly, the sensing network element SF receives the sensing request response from the gNB.

[0245] The sensing request response includes configuration information for the reference signal. This allows the sensing network element (SF) to determine the location of the sensing reference signal resources used to carry the reference signal based on the configuration information.

[0246] By providing reference signal configuration information to sensing network elements, the gNB can help the SF determine whether the reference signal configuration information configured by the gNB for the terminal meets the sensing requirements. For example, if the sensing process requires several measurements, the gNB can determine whether the reference signal configuration information configured by the gNB for the terminal can achieve those measurements.

[0247] Step 1105: The sensing network element (SF) sends a sensing measurement request to the gNB. Correspondingly, the gNB receives the sensing measurement request from the sensing network element (SF).

[0248] The perception measurement request includes information about the perceived target. This information includes at least its identifier. The perceived target is identified by a first-level identifier; that is, the identifier of the perceived target can be a first-level identifier. This perception measurement request is used to request the gNB to perform perception measurements on the perceived target identified by the first-level identifier.

[0249] Step 1106: The terminal sends a reference signal according to the sensing reference signal resource configuration.

[0250] For example, the terminal sends a reference signal on the sensing reference signal resource as indicated by the sensing reference signal resource configuration.

[0251] It is understandable that after the terminal sends the reference signal, the reference signal is transmitted through the reflection points / scattering points / diffraction points on the sensing target. The signal transmitted through the reflection points / scattering points / diffraction points on the sensing target will be referred to as the first signal.

[0252] Step 1107: gNB measures the first signal and obtains the first measurement result corresponding to the point on the sensing target.

[0253] Step 1108: The gNB reports a measurement report to the sensing network element SF, and the sensing network element SF receives the measurement report from the gNB.

[0254] For example, the measurement report includes first-level and second-level identifiers. The first-level and second-level identifiers are used to indicate the identifiers of points on the perceived target.

[0255] Step 1109: The sensing network element processes the first measurement results of the points on the sensing target based on the first-level identifier and the second-level identifier.

[0256] For example, step 1109 can be achieved in the following way: the sensing network element associates or fuses the measurement results (including the first measurement result) that correspond to the same first-level identifier and second-level identifier.

[0257] For example, the first-level identifier includes at least one first bit, and the second-level identifier uses at least one second bit. For instance, if the identifier of a sensing target is represented by two bits, the first-level identifier of sensing target A can be 11, and the first-level identifier of sensing target B can be 00. Reflection points A and B on sensing target A are represented by 0101 and 1010 respectively, and reflection point A on sensing target B is represented by 0101. Assuming multiple measurement results include measurement result 1, measurement result 2, and measurement result 3, where the identifier of the point on the sensing target corresponding to measurement result 1 is 110101, the identifier of the point on the sensing target corresponding to measurement result 2 is 110101, and the identifier of the point on the sensing target corresponding to measurement result 3 is 000101, the sensing device can then associate or fuse measurement result 1 and measurement result 2.

[0258] As shown in Figure 12, Figure 12 illustrates the specific flow of the sensing measurement method provided in this application embodiment, taking the gNB transmitting reference signal terminal receiving reference signal as an example. The method includes:

[0259] Step 1201: The sensing network element SF interacts with the gNB or terminal to exchange sensing capability information and identify whether the gNB or terminal has sensing capability.

[0260] Step 1202: The gNB sends sensing reference signal configuration information to the sensing network element SF. Correspondingly, the sensing network element SF receives the sensing reference signal configuration information from the gNB.

[0261] Step 1203: The sensing network element (SF) sends a sensing request signaling to the terminal, and the terminal receives the sensing request signaling from the sensing network element (SF).

[0262] The perception request signaling is used to request the terminal to report the measurement results of the perceived target. For example, the perception request signaling may include first indication information, which instructs the terminal to report the measurement results of the perceived target.

[0263] Step 1204: The terminal sends a sensing information request to the sensing network element SF, and the sensing network element SF receives the sensing information request from the terminal.

[0264] For example, the perception information request is used to request the perception network element (SF) to send perception auxiliary information.

[0265] As an example, perception assistance information is used by the terminal to determine the location of the gNB or to determine the angle at which it receives a reference signal transmitted by the gNB.

[0266] Step 1205: The sensing network element (SF) sends a sensing information request response message to the terminal. Correspondingly, the sensing network element (SF) receives the sensing information request response message from the terminal.

[0267] For example, the location information of the gNB is included in the perception information request response message.

[0268] Step 1206: The sensing network element SF sends a sensing measurement request to the terminal. The sensing measurement request contains information about the sensing target, which is identified by the first-level identifier.

[0269] As an example, if the sensing measurement request sent by the sensing network element includes the location information of the gNB, step 1205 can be omitted.

[0270] Step 1207: gNB sends a reference signal, and correspondingly, the terminal receives the first signal transmitted by the reference signal through the point on the sensing target.

[0271] For example, the reference signal can be a PRS (Positioning Reference Signal) or a dedicated sensing reference signal.

[0272] Step 1208: The terminal measures the first signal and obtains the first measurement result.

[0273] Step 1209: The terminal sends a measurement report to the sensing network element SF, and the sensing network element SF receives the measurement report from the terminal.

[0274] The measurement report includes a first measurement result, a first-level identifier, and a second-level identifier. For example, the first-level identifier and the second-level identifier are used to indicate the identifier of the point on the sensing target corresponding to the reported first measurement result.

[0275] Step 1210: The sensing network element processes the first measurement results of the points on the sensing target based on the first-level identifier and the second-level identifier.

[0276] As shown in Figure 13, taking the transmission and reception of reference signals by a gNB as an example, a sensing measurement method provided in this application embodiment is described. The method includes:

[0277] Step 1301: The sensing network element SF interacts with the gNB to exchange sensing capability information and identify whether the gNB has sensing capability.

[0278] Step 1302: The sensing network element SF sends a sensing information request to the gNB, and the gNB receives the sensing information request from the sensing network element SF.

[0279] Among them, the perception information request is used to request the gNB to report perception-related system configuration information.

[0280] Step 1303: In response to the sensing information request, the gNB sends a sensing information request response to the sensing network element SF. Correspondingly, the sensing network element SF receives the sensing information request response from the gNB.

[0281] The sensing information request response includes the gNB's location information, etc. Optionally, the sensing information request response may also include: information about a sensing reference signal, which is used to determine the type of the sensing signal.

[0282] Step 1304: The sensing network element SF sends a sensing measurement request to the gNB, and the gNB receives the sensing measurement request from the sensing network element SF.

[0283] For example, a perception measurement request contains information about the perception target, which is identified by a first-level identifier.

[0284] Step 1305: gNB sends a reference signal.

[0285] Step 1306: gNB measures the first signal to obtain the first measurement result.

[0286] The first signal is the reference signal sent by the gNB and transmitted through a point on the sensing target.

[0287] Step 1307: The gNB sends a measurement report to the sensing network element SF, and the sensing network element receives the measurement report from the gNB.

[0288] For example, a measurement report includes: the first measurement result, and a first-level identifier and a second-level identifier. The first-level identifier and the second-level identifier indicate the identifier of the point on the sensing target corresponding to the reported first measurement result.

[0289] Step 1308: The sensing network element processes the first measurement results of the points on the sensing target based on the first-level identifier and the second-level identifier.

[0290] As shown in Figure 14, taking inter-base station transceiver (base station A transmitting to base station B) as an example, the flow of a sensing method provided in this application embodiment is described. The method includes:

[0291] Step 1401: The sensing network element SF interacts with gNB1 and gNB2 to exchange sensing capability information and identify whether gNB1 and gNB2 have sensing capabilities.

[0292] Step 1402: The sensing network element SF sends a sensing information request to gNB1, and gNB1 receives the sensing information request from the sensing network element SF.

[0293] For example, the perception information request is used to request gNB1 to report perception-related system configuration information.

[0294] Step 1403: gNB1 sends a sensing information request response to the sensing network element SF, and the sensing network element SF receives the sensing information request response from gNB1.

[0295] For example, the sensing information request response may contain information about the sensing reference signal, or the location information of gNB1, etc.

[0296] Step 1404: The sensing network element SF sends a sensing measurement request to gNB2, and gNB2 receives the sensing measurement request from the sensing network element SF.

[0297] For example, a perception measurement request contains information about the perception target, which is identified by a first-level identifier.

[0298] Step 1405: gNB1 sends a reference signal.

[0299] Step 1406: gNB2 measures the first signal transmitted from the reference signal sent by gNB1 to gNB2 via the point on the sensing target, and obtains the first measurement result.

[0300] Step 1407: gNB2 will report a measurement report to the sensing network element SF, and the corresponding sensing network element SF will receive the measurement report from gNB2. For example, the measurement report includes a first measurement result, a first-level identifier, and a second-level identifier. The first-level identifier and the second-level identifier indicate the identifier of the point on the sensing target corresponding to the reported first measurement result.

[0301] Step 1408: The sensing network element processes the first measurement results of the points on the sensing target based on the first-level identifier and the second-level identifier.

[0302] As shown in Figure 15, taking the terminal transmitting and receiving reference signals as an example, Figure 15 describes a sensing measurement method provided by an embodiment of this application. The method includes:

[0303] Step 1501: The sensing network element SF interacts with the terminal to obtain sensing capability information and identify whether the terminal has sensing capability.

[0304] Step 1502: The sensing network element (SF) sends a sensing information request to the terminal, and the terminal receives the sensing information request from the sensing network element (SF).

[0305] For example, the perception information request is used to request the terminal to report perception-related system configuration information.

[0306] Step 1503: The terminal sends a sensing information request response to the sensing network element SF, and the sensing network element SF receives the sensing information request response from the terminal.

[0307] For example, an information request response may contain information about a sensing reference signal, or the location information of the terminal.

[0308] Step 1504: The sensing network element (SF) sends a sensing measurement request to the terminal, and the terminal receives the sensing measurement request from the SF.

[0309] For example, a perception measurement request contains information about the perception target, which is identified by a first-level identifier.

[0310] Step 1505: The terminal sends a reference signal.

[0311] Step 1506: The terminal measures the reference signal it sends and obtains the first measurement result.

[0312] Step 1507: The terminal reports a measurement report to the sensing network element SF, and the sensing network element receives the measurement report from the terminal.

[0313] For example, a measurement report includes a first measurement result, as well as a first-level identifier and a second-level identifier. The first-level identifier and the second-level identifier indicate the identifier of the point on the sensing target corresponding to the reported first measurement result.

[0314] Step 1508: The sensing network element processes the first measurement results of the points on the sensing target based on the first-level identifier and the second-level identifier.

[0315] As shown in Figure 16, taking terminal A sending a reference signal and terminal B receiving the reference signal as an example, Figure 16 describes the sensing process provided by the embodiments of this application:

[0316] Step 1601: The sensing network element SF interacts with terminal A and terminal B to exchange sensing capability information and identify whether terminal A and terminal B have sensing capabilities.

[0317] Step 1602: The sensing network element SF sends a sensing information request to terminal A, and correspondingly, terminal A receives the sensing information request from the sensing network element SF. For example, the sensing information request is used to request terminal A to report sensing-related system configuration information.

[0318] Step 1603: Terminal A sends a sensing information request response to the sensing network element SF, and correspondingly, the sensing network element SF receives the sensing information request response from Terminal A.

[0319] For example, the perception information request response may include: the location information of terminal A, etc. Optionally, the perception information request response may also include: information about the reference signal.

[0320] Step 1604: The sensing network element SF sends a sensing measurement request to the terminal B, and the terminal B receives the sensing measurement request from the sensing network element SF.

[0321] For example, a perception measurement request contains information about the perception target, which is identified by a first-level identifier.

[0322] Step 1605: Terminal A sends a reference signal.

[0323] Step 1606: Terminal B receives the reference signal sent by Terminal A and performs measurement to obtain the first measurement result.

[0324] Step 1607: Terminal B reports a measurement report to the sensing network element SF, and the corresponding sensing network element SF receives the measurement report from Terminal B.

[0325] For example, a measurement report includes a first measurement result, a first-level identifier, and a second-level identifier. The first-level identifier and the second-level identifier indicate the identifiers of the points on the sensing target corresponding to the reported measurement results.

[0326] Step 1608: The sensing network element processes the first measurement results of the points on the sensing target based on the first-level identifier and the second-level identifier.

[0327] It should be noted that the sensing network element SF, which involves interacting with the base station or terminal, can be deployed on the RAN side or in the core network. The sensing network element SF can be the same network element as the LMF, or they can be different network elements. The measurement report also includes measurement data obtained from receiving signals or channel processing. This measurement data can include one or more of the following: delay, distance, angle, intensity, Doppler information, etc. The first-level identifier sent by the sensing network element SF can be included in the sensing measurement request message or in the interaction messages between other sensing network elements and the base station or terminal. The first-level identifier reported by the sensing device (base station or terminal) reporting the first measurement result can be the same as or correspond to the identifier of the sensing target sent by the sensing network element SF. The second-level identifier can be generated by the sensing device (base station or terminal) reporting the first measurement result.

[0328] In the above embodiments, when the sensing device (base station or terminal) reports the measurement results to the sensing network element SF, the identification of the reported point is introduced with two levels of identification to identify the point on the sensing target. The first level of identification corresponds to the identification of the sensing target, and the second level of identification corresponds to the identification of the reflection point / scattering point / diffraction point. The sensing network element can then identify and associate or fuse the same point in multiple measurement results or measurement results from multiple base stations to improve the sensing accuracy or resolution.

[0329] As shown in Figure 17, taking the terminal transmitting a reference signal and the gNB receiving the reference signal as an example, Figure 17 describes a sensing measurement method provided by an embodiment of this application. The method includes:

[0330] Step 1701: The sensing network element SF interacts with the gNB or terminal to exchange sensing capability information and identify whether the gNB or terminal has sensing capability.

[0331] Step 1702: The sensing network element SF sends a sensing request signaling to the gNB, and the gNB receives the sensing request signaling from the sensing network element SF.

[0332] For example, the perception request signaling is used to request the gNB to configure perception reference signal resources for the terminal or to request the gNB to report the configuration information of the terminal's perception reference signals.

[0333] As an example, the perception request signaling includes the terminal's identifier and indication information, which helps the gNB determine which terminal to configure perception reference signal resources for, or which terminal's perception reference signal configuration information to report.

[0334] Step 1703: The gNB configures sensing reference signal resources or a set of sensing reference signal resources for the terminal. The sensing reference signal can be an SRS (Sounding Reference Signal) or a dedicated sensing reference signal.

[0335] As an example, if the gNB has already configured sensing reference signal resources or a set of sensing reference signal resources for the terminal after receiving the sensing request signaling, then step 1703 can be omitted; if the gNB has not yet configured sensing reference signal resources or a set of sensing reference signal resources for the terminal, then the gNB executes step 1703.

[0336] Step 1704: The gNB sends a sensing request response to the sensing network element, and correspondingly, the gNB receives the sensing request response from the sensing network element. For example, the sensing request response contains configuration information of the sensing reference signal.

[0337] Step 1705: The sensing network element SF sends a sensing measurement request to the gNB, and the gNB receives the sensing measurement request from the SF.

[0338] For example, a sensing measurement request may contain information about the sensing target. This information may include the identifiers of one or more boundary points on the sensing target, such as the coordinates of one or more boundary points, or the latitude and longitude information of one or more boundary points, or the angle information of one or more boundary points relative to a reference point, or the distance information of one or more boundary points relative to a reference point.

[0339] Step 1706: The terminal sends a reference signal according to the sensing reference signal resource configuration.

[0340] Step 1707: The gNB measures the first signal and obtains the first measurement result. The first signal is the signal transmitted after the reference signal sent by the terminal passes through a point on the sensing target.

[0341] Step 1708: gNB reports the measurement report, and correspondingly, SF receives the measurement report from gNB.

[0342] The measurement report includes a first measurement result, identifiers of one or more boundary points, and identifiers of points on the sensing target. This measurement report indicates the identifiers of the points corresponding to the reported first measurement result. The identifiers of one or more boundary points are used to identify the sensing target.

[0343] Step 1709: SF processes the first measurement result based on the identification of one or more boundary points and the identification of points on the perceived target.

[0344] As shown in Figure 18, taking the gNB transmitting a reference signal and the terminal receiving the reference signal as an example, Figure 18 describes a sensing measurement method provided by an embodiment of this application. The method includes:

[0345] Step 1801: The sensing network element SF interacts with the gNB or terminal to exchange sensing capability information and identify whether the gNB or terminal has sensing capability.

[0346] It is worth noting that if the sensing network element (SF) is configured to determine whether the gNB or terminal has sensing capabilities, then step 1801 can be omitted. Alternatively, the sensing network element (SF) can obtain information about the terminal's sensing capabilities and the gNB's sensing capabilities by interacting with the terminal. Or, the sensing network element (SF) can obtain information about the terminal's sensing capabilities and the gNB's sensing capabilities by interacting with the gNB. Alternatively, the sensing network element (SF) can determine whether the terminal has sensing capabilities by interacting with the terminal and whether the gNB has sensing capabilities by interacting with the gNB.

[0347] Step 1802: gNB sends sensing reference signal configuration information to sensing network element SF.

[0348] Step 1803: The sensing network element (SF) sends a sensing request signaling to the terminal, and the terminal receives the sensing request signaling from the sensing network element (SF).

[0349] Among them, the perception request signaling is used to request the terminal to report perception-related measurement results.

[0350] Step 1804: The terminal sends a sensing information request to the sensing network element SF, and the sensing network element SF receives the sensing information request from the terminal. The sensing information request is used to request the sensing network element SF to send sensing auxiliary information.

[0351] Step 1805: The sensing network element (SF) sends a sensing information request response to the terminal, and the terminal receives the sensing information request response from the sensing network element (SF).

[0352] For example, the perception information request response message contains information about the perception target, which is identified by a first-level identifier.

[0353] Step 1806: The sensing network element (SF) sends a sensing measurement request to the terminal, and the terminal receives the sensing measurement request from the sensing network element (SF).

[0354] For example, a perception measurement request may contain information about the perceived target. This information may include identifiers of one or more boundary points.

[0355] Step 1807: gNB sends a reference signal to the terminal.

[0356] For example, the sensing reference signal can be a PRS (Positioning Reference Signal) or a dedicated sensing reference signal.

[0357] It is understandable that the reference signal sent by the gNB to the terminal is transmitted back to the gNB after passing through a point on the sensing target. For ease of understanding, the signal transmitted by the gNB to the terminal after passing through a point on the sensing target can be considered the first signal.

[0358] Step 1808: The terminal measures the first signal and obtains the first measurement result.

[0359] Step 1809: The terminal sends a measurement report to the sensing network element SF. The measurement report includes a first measurement result, the identifiers of one or more boundary points, and the identifiers of points on the sensing target, indicating the identifiers of the points on the sensing target corresponding to the reported first measurement result.

[0360] Step 1810: SF processes the first measurement result based on the identification of one or more boundary points and the identification of points on the perceived target.

[0361] As shown in Figure 19, Figure 19 illustrates a sensing measurement method provided by an embodiment of this application in a gNB self-transmitting and self-receiving reference signal scenario. The method includes:

[0362] Step 1901: The sensing network element SF interacts with the gNB to exchange sensing capability information and identify whether the gNB has sensing capability.

[0363] Step 1902: The sensing network element SF sends a sensing information request to the gNB, and the gNB receives the sensing information request from the sensing network element SF.

[0364] For example, the perception information request is used to request the gNB to report perception-related system configuration information.

[0365] Step 1903: The gNB sends a sensing information request response to the sensing network element SF, and the sensing network element SF receives the sensing information request response from the gNB.

[0366] For example, the perception information request response may include information from reference signals, or the location information of the gNB, etc.

[0367] By carrying the location information of the gNB, the SF can process the measurement results based on the location information of the gNB.

[0368] Step 1904: The sensing network element (SF) sends a sensing measurement request to the gNB, and the gNB receives the sensing measurement request from the sensing network element (SF). For example, the sensing measurement request contains relevant information about the sensing target, which may include the identifiers of one or more boundary points on the sensing target.

[0369] Step 1905: gNB sends a reference signal.

[0370] It is understandable that the reference signal sent by the gNB is retransmitted to the gNB after passing through a point on the sensing target. For ease of understanding, the signal that is the reference signal sent by the gNB and then transmitted to the gNB after passing through a point on the sensing target can be considered the first signal.

[0371] Step 1906: gNB measures the first signal and obtains the first measurement result.

[0372] Step 1907: The gNB reports a measurement report to the sensing network element SF, and the sensing network element SF receives the measurement report from the gNB.

[0373] For example, a measurement report includes a first measurement result, identifiers of one or more boundary points on the sensing target, and identifiers of points on the sensing target, to indicate the identifiers of points on the sensing target corresponding to the reported first measurement result.

[0374] Step 1908: SF processes the first measurement result based on the identification of one or more boundary points and the identification of points on the perceived target.

[0375] As shown in Figure 20, this is a flowchart illustrating a sensing measurement method in a scenario where reference signals are transmitted and received between different base stations (gNB1 transmits, gNB2 receives). The method includes:

[0376] Step 2001: The sensing network element SF interacts with gNB1 and gNB2 to exchange sensing capability information and identify whether gNB1 and gNB2 have sensing capabilities.

[0377] Step 2002: The sensing network element SF sends a sensing information request to gNB1, and gNB1 receives the sensing information request from the sensing network element SF.

[0378] For example, the perception information request is used to request gNB1 to report perception-related system configuration information.

[0379] Step 2003: gNB1 sends a sensing information request response to the sensing network element SF, and the sensing network element SF receives the sensing information request response from gNB1.

[0380] For example, the sensing information request response may contain information about the sensing reference signal, or the location information of gNB1, etc.

[0381] Step 2004: The sensing network element SF sends a sensing measurement request to gNB2. gNB2 receives the sensing measurement request from the sensing network element SF.

[0382] For example, a perception measurement request may contain information about the perceived target, which may include the identifiers of one or more boundary points on the perceived target.

[0383] Step 2005: gNB1 sends a reference signal in the configuration of the sensing reference signal resources.

[0384] It is understood that in this embodiment, the reference signal sent by gNB1 is transmitted to gNB2 after passing through a point on the sensing target. For ease of understanding, the signal transmitted by gNB1 to gNB2 after passing through a point on the sensing target can be considered as the first signal.

[0385] Step 2006: gNB2 receives the first signal and performs measurement to obtain the first measurement result.

[0386] Step 2007: gNB2 sends a measurement report to the sensing network element SF, and the sensing network element SF receives the measurement report from gNB2.

[0387] For example, the measurement report includes the first measurement result, the identifiers of one or more boundary points on the sensing target, and the identifiers of points on the sensing target, indicating the identifiers of the points corresponding to the first measurement result reported.

[0388] Step 2008: SF processes the first measurement result based on the identification of one or more boundary points and the identification of points on the perceived target.

[0389] As shown in Figure 21, Figure 21 illustrates a sensing measurement method provided by an embodiment of this application in a scenario where the terminal transmits and receives reference signals independently. The method includes:

[0390] Step 2101: The sensing network element SF interacts with the terminal to obtain sensing capability information and identify whether the terminal has sensing capability.

[0391] Step 2102: The sensing network element (SF) sends a sensing information request to the terminal. Correspondingly, the terminal receives the sensing information request sent by the sensing network element (SF). For example, the sensing information request is used to request the terminal to report sensing-related auxiliary information.

[0392] Step 2103: The terminal sends a sensing information request response to the sensing network element SF, and the sensing network element SF receives the sensing information request response from the terminal.

[0393] For example, a perception information request response may contain information about a perception reference signal, or the location information of the terminal.

[0394] Step 2104: The sensing network element (SF) sends a sensing measurement request to the terminal, and the terminal receives the sensing measurement request from the sensing network element (SF).

[0395] For example, a perception measurement request may contain information about the perceived target, which may include the identifiers of one or more boundary points on the perceived target.

[0396] Step 2105: The terminal sends a reference signal.

[0397] Step 2106: The terminal measures the first signal and obtains the first measurement result.

[0398] Step 2107: The terminal reports a measurement report to the sensing network element SF, and the sensing network element SF receives the measurement report from the terminal.

[0399] For example, the measurement report includes the first measurement result, the identifiers of one or more boundary points on the sensing target and the identifiers of points on the sensing target, and the identifiers of the points on the sensing target corresponding to the first measurement result reported.

[0400] Step 2108: SF processes the first measurement result based on the identification of one or more boundary points and the identification of points on the perceived target.

[0401] As shown in Figure 22, this is a flowchart of a sensing measurement method provided in an embodiment of this application in a scenario where different terminals transmit and receive reference signals. The method includes:

[0402] Step 2201: The sensing network element SF interacts with terminal A and terminal B to exchange sensing capability information and identify whether terminal A and terminal B have sensing capabilities.

[0403] Step 2202: The sensing network element SF sends a sensing information request to terminal A, and correspondingly, terminal A receives the sensing information request from the sensing network element SF. For example, the sensing information request is used to request terminal A to report sensing-related system configuration information.

[0404] Step 2203: Terminal A sends a sensing information request response to the sensing network element SF, and the sensing network element SF receives the sensing information request response from Terminal A.

[0405] For example, the perception information request response may contain information about the perception reference signal, or the location information of terminal A, etc.

[0406] Step 2204: The sensing network element SF sends a sensing measurement request to the terminal B, and the terminal B receives the sensing measurement request from the sensing network element SF.

[0407] For example, a perception measurement request may contain information related to the perception target, which may include the identifiers of one or more boundary points on the perception target.

[0408] Step 2205 Terminal A sends a reference signal.

[0409] Step 2206: Terminal B measures the first signal to obtain the first measurement result. The first signal is the reference signal sent by Terminal A transmitted through a point on the sensing target.

[0410] Step 2207: Terminal B sends a measurement report to the sensing network element SF, and the sensing network element SF receives the measurement report accordingly.

[0411] For example, a measurement report may include the first measurement result, the identifiers of one or more boundary points on the sensing target, and the identifiers of points on the sensing target, to indicate the identifiers of the points on the sensing target corresponding to the reported first measurement result.

[0412] For example, the measurement report may also include measurement data obtained from the first signal or channel processing. The measurement data may include one or more of the following: time delay, distance, angle, intensity, Doppler information, etc.

[0413] Step 2208: SF processes the first measurement result based on the identification of one or more boundary points and the identification of points on the perceived target.

[0414] It should be noted that the sensing network element SF, which involves interacting with the base station or terminal, can be deployed on the RAN side or in the core network. The sensing network element SF can be the same network element as the LMF, or they can be different network elements. The boundary point identifiers sent by the sensing network element SF can be included in the sensing measurement request or in other interaction messages between the sensing network element and the base station or terminal. The boundary point identifiers reported by the sensing device (base station or terminal) reporting the measurement results can be the same as or correspond to the boundary point identifiers sent by the sensing network element SF. The point identifiers can be generated by the sensing device (base station or terminal) reporting the measurement results.

[0415] In the embodiments shown in Figures 16-18, when the sensing device (base station or terminal) reports the first measurement result to the sensing network element SF, it also reports the identifiers of one or more boundary points and the identifiers of points on the sensing target. Accordingly, the sensing network element can determine the sensing target based on the reported identifiers of one or more boundary points, and determine which point on the sensing target the first measurement result refers to based on the point identifiers. This allows it to subsequently correlate or fuse multiple measurement results corresponding to the same point on the sensing target, improving sensing accuracy or resolution.

[0416] Figure 23 illustrates the specific flow of a sensing measurement method provided in this application embodiment, where the terminal transmits a reference signal and the gNB receives a reference signal. The method includes:

[0417] Steps 2301 to 2304 are the same as steps 1101 to 1104, and will not be repeated here.

[0418] Step 2305: The sensing network element SF sends a sensing measurement request to the gNB, and the gNB receives the sensing measurement request from the sensing network element SF.

[0419] The perception measurement request includes information about the perception target and indication information of the point identifiers in the measurement report. The perception target is identified by the first-level identifier, and the indication information of the point identifiers in the measurement report can be the identifiers of multiple points or the identifier range of a single point.

[0420] Steps 2306 and 2307 are the same as steps 1106 and 1107, and will not be repeated here.

[0421] Step 2308: The gNB reports a measurement report to the sensing network element SF, and the sensing network element SF receives the measurement report from the gNB.

[0422] For example, the measurement report includes first-level and second-level identifiers. The first-level and second-level identifiers are used to indicate the identifiers of points on the perceived target.

[0423] The first-level identifier is the same as or corresponds to the identifier of the perceived target, and the second-level identifier is one of the multiple point identifiers in the perception measurement request or one of the point identifier ranges.

[0424] Step 2309: The sensing network element processes the first measurement results of the points on the sensing target based on the first-level identifier and the second-level identifier.

[0425] As shown in Figure 24, Figure 24 illustrates the specific flow of the sensing measurement method provided in this application embodiment under the scenario of gNB transmitting reference signal and terminal receiving reference signal. The method includes:

[0426] Steps 2401 to 2404 are the same as steps 1201 to 1204, and will not be repeated here.

[0427] Step 2405: The sensing network element SF sends a sensing measurement request to the gNB, and the gNB receives the sensing measurement request from the sensing network element SF.

[0428] The perception measurement request includes information about the perception target and indication information of the point identifiers in the measurement report. The perception target is identified by the first-level identifier, and the indication information of the point identifiers in the measurement report can be the identifiers of multiple points or the identifier range of a single point.

[0429] Steps 2406 to 2410 are the same as steps 1206 to 1210, and will not be repeated here.

[0430] The difference is that in step 2409, the first-level identifier in the measurement report sent by the terminal to the SF is the same as or corresponds to the identifier of the perceived target, and the second-level identifier is one of the multiple point identifiers in the perception measurement request or one of the point identifier ranges.

[0431] As shown in Figure 25, Figure 25 illustrates a sensing measurement method provided by an embodiment of this application in a scenario where a gNB transmits and receives a reference signal. The method includes:

[0432] Steps 2501 to 2507 are the same as steps 1301 to 1307, and will not be repeated here.

[0433] The difference is that, in the embodiment shown in Figure 25, the sensing measurement request sent by the sensing network element SF to the gNB in ​​step 2504 includes not only the information of the sensing target, but also the indication information of the point identifier in the measurement report. The sensing target is identified by the first-level identifier, and the indication information of the point identifier in the measurement report can be the identifier of multiple points or the identifier range of a single point.

[0434] In step 2507, the first-level identifier in the measurement report sent by the gNB to the sensing network element SF is the same as or corresponds to the identifier of the sensing target, and the second-level identifier is one of the multiple point identifiers in the sensing measurement request or one of the point identifier ranges.

[0435] As shown in Figure 26, which uses inter-base station transceiver (base station A transmitting to base station B) as an example, Figure 26 describes the flow of a sensing method provided in an embodiment of this application. The method includes:

[0436] Steps 2601 to 2607 are the same as steps 1401 to 1407, except that in the embodiment shown in Figure 26, the sensing measurement request sent by the sensing network element SF to the gNB in ​​step 2604 includes not only the information of the sensing target, but also the indication information of the point identifier in the measurement report. The sensing target is identified by the first-level identifier, and the indication information of the point identifier in the measurement report can be the identifier of multiple points or the identifier range of a point.

[0437] In step 2607, the first-level identifier in the measurement report sent by the gNB to the sensing network element SF is the same as or corresponds to the identifier of the sensing target, and the second-level identifier is one of the multiple point identifiers in the sensing measurement request or one of the point identifier ranges.

[0438] As shown in Figure 27, taking the transmission and reception of reference signals by a terminal as an example, Figure 27 describes a sensing measurement method provided by an embodiment of this application. The method includes:

[0439] Steps 2701 to 2707 are the same as steps 1501 to 1507, except that in the embodiment shown in Figure 27, the sensing measurement request sent by the sensing network element SF to the gNB in ​​step 1504 includes not only the information of the sensing target, but also the indication information of the point identifier in the measurement report. The sensing target is identified by the first-level identifier, and the indication information of the point identifier in the measurement report can be the identifier of multiple points or the identifier range of a single point.

[0440] In step 2707, the first-level identifier in the measurement report sent by the gNB to the sensing network element SF is the same as or corresponds to the identifier of the sensing target, and the second-level identifier is one of the multiple point identifiers in the sensing measurement request or one of the point identifier ranges.

[0441] As shown in Figure 28, taking terminal A sending a reference signal and terminal B receiving the reference signal as an example, Figure 28 describes the sensing process provided by the embodiments of this application:

[0442] Steps 2801 to 2807 are the same as steps 1601 to 1607, except that in the embodiment shown in Figure 28, the sensing measurement request sent by the sensing network element SF to the gNB in ​​step 1604 includes not only the information of the sensing target, but also the indication information of the point identifier in the measurement report. The sensing target is identified by the first-level identifier, and the indication information of the point identifier in the measurement report can be the identifier of multiple points or the identifier range of a point.

[0443] In step 2807, the first-level identifier in the measurement report sent by the gNB to the sensing network element SF is the same as or corresponds to the identifier of the sensing target, and the second-level identifier is one of the multiple point identifiers in the sensing measurement request or one of the point identifier ranges.

[0444] As shown in Figure 29, this embodiment corresponds to the O-RAN architecture. DU is the network element that performs signal reception and processing, and CU is responsible for measurement and control. Its implementation process is as follows:

[0445] Step 2901: Configuration information for the exchange of reference signals between SF, terminal and DU.

[0446] Step 2902: The sensing network element SF sends a sensing measurement request to the DU, and correspondingly, the DU in the wireless access network device receives the sensing measurement request.

[0447] For example, a perception measurement request contains information about the perception target, which is identified by a first-level identifier.

[0448] Step 2903: The terminal sends a reference signal to the DU on the configured reference signal resources.

[0449] Step 2904: The reference signal sent by the DU measurement terminal is used to obtain the first measurement result.

[0450] Step 2905: The DU sends a measurement report to the CU. The corresponding CU receives the measurement report from the DU. For example, the measurement report includes a first measurement result, a first-level identifier, and a second-level identifier. The first-level identifier and the second-level identifier indicate the identifier of the sensing target point corresponding to the reported first measurement result.

[0451] Step 2906: The CU sends a measurement report to the sensing network element SF. Correspondingly, the sensing network element SF receives the measurement report from the CU.

[0452] As an example, step 2905 can be replaced by: the DU sending a first measurement report to the CU, the first measurement report including a first measurement result, a first-level identifier, and a second-level identifier; then step 2906 can be replaced by: the CU processing the first measurement report to obtain a second measurement report, and sending the second measurement report as the measurement report to the SF. The CU processing of the first measurement report could involve the CU adding a header to the first measurement report, etc.

[0453] As an example, step 2905 can be replaced by: DU sending the first measurement result and the first-level identifier to CU, and then step 2906 can be replaced by: CU generating a measurement report based on the first measurement result and the first-level identifier, and sending the measurement report to SF. For example, CU can add the first-level identifier and packet header to the measurement report.

[0454] The wireless access network device (DU or CU) reports the measurement results to the sensing network element (SF). The measurement report contains a first-level identifier and a second-level identifier, indicating the identifier of the point on the sensing target corresponding to the reported measurement result. The sensing network element can identify and associate or fuse measurement results corresponding to the same point identifier from multiple measurement results or measurement results from multiple base stations to improve sensing accuracy or resolution.
