Description

Method and communication device for transmitting measurement information

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 8, 2023, with application number 202311688874.6 and application name “Method and communication device for sending measurement information”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more particularly, to a method and a communication device for sending measurement information. Background Art

[0003] The basic principle of deformation detection is that a measuring station continuously transmits a fixed-phase signal, collects echo signals at different times, and then correlates the signals to determine the phase variation pattern. This phase variation can be converted into deformation. However, current cellular network architectures do not support the detection and reporting of deformation information. Therefore, how to implement deformation detection of passive targets within the cellular network positioning framework and combine the characteristics of positioning has become an urgent problem. Summary of the Invention

[0004] The present application provides a method and a communication device for sending measurement information, which can detect and report deformation of a target within the positioning framework of a cellular network.

[0005] In a first aspect, a method for sending measurement information is provided. The method can be performed by a first device, or by a module (such as a processor, chip, or chip system) applied to the first device, or by a logical node, logic module, or software that can implement all or part of the functions of the first device, without limitation.

[0006] The method includes: obtaining first measurement information based on a first reference signal, the first measurement information including information of N coordinates, the N coordinates being associated with a first path, and N being a positive integer; obtaining second measurement information based on a second reference signal, the second measurement information including information of M coordinates, the M coordinates being associated with the first path, and M being a positive integer; and sending the first measurement information and the second measurement information.

[0007] For example, the first device is a network device or a terminal device.

[0008] It can be understood that since the N coordinates are associated with the first path, and information about the N coordinates is obtained based on the first reference signal, the first reference signal can also be considered to be associated with the first path. For example, the first reference signal being associated with the first path can specifically be transmitted on the first path.

[0009] Optionally, the first path is associated with the first target. For example, the association between the first path and the first target may specifically be that the first target is located in the first path.

[0010] In this application, the first device acquiring the first measurement information based on the first reference signal can be understood as the first device acquiring the first measurement information based on the echo signal of the first reference signal. For example, the first reference signal encounters a first target during transmission along a first path, and generates an echo signal after refraction, reflection, or scattering on the surface of the first target. The first device receives the echo signal and acquires the first measurement information based on the echo signal.

[0011] In the above technical solution, the first device can obtain corresponding measurement information based on different reference signals, and then report the obtained measurement information to the device that initiates the deformation measurement, so that the device that initiates the deformation measurement can determine the deformation of the target based on the received measurement information. This method enables deformation detection and reporting of passive targets within the positioning framework of the cellular network. In addition, the traditional deformation detection principle can only solve the deformation detection of a single point, and cannot solve the deformation detection of an extended target. The measurement information obtained based on the reference signal of the present application includes information on multiple coordinates, thereby enabling deformation detection and reporting of a target (i.e., multiple points).

[0012] In certain implementations of the first aspect, N is equal to M.

[0013] In certain implementations of the first aspect, information on L coordinates in the information on M coordinates is related to information on L coordinates in the information on N coordinates, where L is a positive integer.

[0014] For example, the information of L coordinates in the information of M coordinates is correlated with the information of L coordinates in the information of N coordinates, and the information of L coordinates in the information of M coordinates is correlated with the information of L coordinates in the information of N coordinates in a one-to-one manner.

[0015] In certain implementations of the first aspect, the information of N coordinates indicates N coordinates, and the information of M coordinates indicates M coordinates.

[0016] In certain implementations of the first aspect, the information of N coordinates indicates N coordinates, and the information of M coordinates includes differential information of the M coordinates.

[0017] In certain implementations of the first aspect, the differential information of the M coordinates indicates M differential coordinates corresponding to the M coordinates or M differential distances corresponding to the M coordinates.

[0018] In certain implementations of the first aspect, the coordinate types corresponding to the N coordinates and the M coordinates are Cartesian coordinates or polar coordinates.

[0019] In certain implementations of the first aspect, the first reference signal and the second reference signal are one of the following reference signals: positioning reference signal PRS, sounding reference signal SRS, channel state information-reference signal CSI-RS, primary synchronization signal PSS, secondary synchronization signal SSS, demodulation reference signal DMRS, perception signal, and detection signal.

[0020] In a second aspect, a communication device is provided, which is configured to execute the method provided in the first aspect. Specifically, the communication device may include units and / or modules configured to execute the method provided in the first aspect or any one of the above implementations of the first aspect.

[0021] In one implementation, the communication apparatus is a first device. When the communication apparatus is the first device, the transceiver unit may be a transceiver or an input / output interface; and the processing unit may be at least one processor. Alternatively, the transceiver may be a transceiver circuit. Alternatively, the input / output interface may be an input / output circuit.

[0022] In another implementation, the communication device is a chip, chip system, or circuit used in the first device. When the communication device is a chip, chip system, or circuit used in the first device, the transceiver unit may be an input / output interface, interface circuit, output circuit, input circuit, pin, or related circuit on the chip, chip system, or circuit; and the processing unit may be at least one processor, processing circuit, or logic circuit.

[0023] For example, the first device is a terminal device or a network device.

[0024] In a third aspect, a communication device is provided, comprising: a memory for storing programs; and at least one processor for executing computer programs or instructions stored in the memory to execute the method provided in the first aspect or any one of the above-mentioned implementations of the first aspect.

[0025] In one implementation, the communication apparatus is a first device. For example, the first device is a terminal device or a network device.

[0026] In another implementation, the apparatus is a chip, a chip system, or a circuit used in the first device.

[0027] In a fourth aspect, a computer-readable storage medium is provided, which stores a computer program. When the computer program is run on a computer, the method provided by the first aspect or any one of the above-mentioned implementations of the first aspect is executed.

[0028] In a fifth aspect, a computer program product comprising instructions is provided. When the computer program product is run on a computer, the computer is caused to execute the method provided by the first aspect or any one of the above-mentioned implementations of the first aspect.

[0029] In a sixth aspect, a chip is provided, which includes a processor and a communication interface. The processor reads instructions stored in a memory through the communication interface and executes the method provided by the first aspect or any one of the above-mentioned implementation methods of the first aspect.

When the computer program or instructions are executed, the processor is used to execute the method provided by the above-mentioned first aspect or any one of the above-mentioned implementation methods of the first aspect.

For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Wherein a, b and c can be single or multiple, respectively.

[0043] Third, throughout this application, the terms "first," "second," and various numerical references are used for descriptive purposes only and are not intended to limit the scope of the embodiments of this application. For example, they are used to distinguish between different messages, rather than to describe a specific order or precedence. It should be understood that these references are interchangeable, where appropriate, to allow for the description of scenarios beyond the embodiments of this application.

[0044] Fourth, in this application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions.

[0045] Fifth, in this application, "indication" can include direct indications and indirect indications. When describing that a certain indication information indicates A, it can include that the indication information directly indicates A or indirectly indicates A, but it does not mean that the indication information must contain A.

[0046] Sixth, in this application, "sending information to ... (e.g., a device)" can be understood as the destination of the information being the device. This can include sending information to the device directly or indirectly. "Receiving information from ... (e.g., a device) or receiving information from ...

[0049] Seventh, the arrows or boxes shown by dotted lines in the schematic diagrams of the accompanying drawings in the specification of this application represent optional steps or optional modules.

[0050] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) system or new radio (NR) and future communication systems, vehicle-to-other devices (V2X), where V2X may include vehicle to network (V2N), vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to pedestrian (V2P), etc., long term evolution-vehicle (LTE-V), Internet of Vehicles, machine type communication (MTC), Internet of Things (IoT), etc. things, IoT), long term evolution-machine (LTE-M), machine to machine (M2M), etc.

[0051] The terminal device in the embodiments of the present application may refer to user equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, an audio device, a terminal device in a future 5G network or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0052] The terminal device in this application can also be a road side unit (RSU). RSU is a facility deployed on the roadside for auxiliary communication in the vehicle-mounted delay-tolerant network. It is directly connected to the backbone network and can communicate wirelessly with the vehicle. Compared with the vehicles in the vehicle-mounted delay-tolerant network, RSU has better communication capabilities, coverage and transmission speed, and can communicate with multiple vehicles at the same time. In addition, RSU has a large storage space that can store information and increase the probability of communication. Therefore, by deploying relevant RSU in the road traffic system, on the one hand, it can effectively solve the existing vehicle-mounted Internet access problem, and on the other hand, it can greatly increase the communication opportunities between vehicles. By caching messages through RSU, efficient transmission of messages between vehicles can be achieved.

[0053] Exemplarily, the terminal device may include: a radio resource control (RRC) signaling interaction module, a media access control (MAC) signaling interaction module, and a physical (PHY) signaling interaction module. Among them, the RRC signaling interaction module may be: a module used by the network device and the terminal device to send and receive RRC signaling. The MAC signaling interaction module may be: a module used by the network device and the terminal device to send and receive MAC control element (CE) (MAC-CE) signaling. PHY signaling and data may be: a module used by the network device and the terminal device to send and receive uplink control signaling or downlink control signaling, uplink and downlink data, or downlink data.

[0054] The network device in the embodiment of the present application can be a device for communicating with a terminal device, and the network device includes but is not limited to: an evolved nodeB (eNB or eNodeB) in an LTE system, a wireless controller in a cloud radio access network (CRAN) scenario, a radio network controller (RNC), a base station controller (BSC), a home base station (for example, home evolved nodeB, or home nodeB, HNB), a baseband unit (BBU), or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN network, etc., and can be an access point (AP) in a wireless local area network (WLAN), a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., and can be a new wireless system (new The gNB or transmission point (TRP or TP) in a 5G radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, is not limited in the embodiments of the present application. All or part of the functions of the network device in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The network device in this application may also be a logical node, logical module or software that can implement all or part of the functions of the network device.

[0055] In some deployments, the gNB may include a centralized unit (CU) and a distributed unit (DU). The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. The AAU implements some physical layer processing functions, RF processing, and active antenna-related functions. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by a combination of the DU and the AAU. It is understood that the network device may include one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be classified as a network device in an access network (RAN) or a network device in a core network (CN), which is not limited in this application.

[0056] The network device in the embodiment of the present application may also be an open radio access network (O-RAN) device, which may also be referred to as a RAN node. Multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, and different RAN nodes respectively implement part of the functions of the network device. As an example, the RAN node may be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). Among them, the CU and DU may be set separately, or may also be included in the same network element, such as a BBU. The RU may be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). For example, in some deployments, the network device may include a centralized unit (CU) and a DU. In different systems, CU (or CU-CP and CU-UP), DU, or RU may also have different names, but those skilled in the art will understand their meanings. For example, in the ORAN system, CU may also be referred to as O-CU (Open CU), DU may also be referred to as O-DU (Open DU), CU-CP may also be referred to as O-CU-CP (Open CU-CP), CU-UP may also be referred to as O-CU-UP (Open CU-UP), and RU may also be referred to as O-RU (Open RU). For convenience of description, this application uses CU, CU-CP, CU-UP, DU and / or RU as examples for description. Any unit in the CU (or CU-CP, CU-UP), DU and / or RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0057] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0058] Table 1

[0059] It should be noted that, in the ORAN system, the network device in this application may be one or more network elements in Table 1 above.

[0060] The following describes the architecture of the CU and DU of an access network device. The access network device includes at least one CU and at least one DU. Optionally, the access network device also includes at least one RU.

[0061] The following is an introduction using the example of an access network device including a CU and a DU. The CU has some functions of the core network, and the CU may include a CU-CP and a CU-UP. The CU and the DU may be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (for example, the RRC layer and / or the SDAP layer). The DU is configured to implement the functions of the protocol layers below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the physical (PHY) layer). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0062] When a CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane functions of the CU, and the CU-UP is used to implement the user plane functions of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, the CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0063] The CU-CP can interact with network elements in the core network that implement control plane functions. The network elements in the core network that implement control plane functions can be access and mobility function network elements, such as the access and mobility management function (AMF) in the 5G system. The access and mobility function network element is responsible for mobility management in the mobile network, such as location update of terminal devices, registration network of terminal devices, and switching of terminal devices.

[0064] The CU-UP can interact with network elements in the core network that implement user plane functions. Network elements in the core network that implement user plane functions, such as the User Plane Function (UPF) in the 5G system, are responsible for forwarding and receiving data in terminal devices.

[0065] The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements. For example, according to the delay, the functions whose processing time needs to meet the smaller delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.

[0066] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0067] It should be noted that the network device can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the aforementioned device or apparatus, and this application does not limit this. It should be noted that in this application, when referring to a network device, it can refer to the network device itself, or it can refer to a chip, functional module or integrated circuit in the network device that performs the method provided in this application, and this application does not limit this.

[0068] To facilitate understanding of the embodiments of the present application, a communication system to which the embodiments of the present application may be applied is first described.

[0069] FIG1 is a schematic diagram of a wireless communication system 100 applicable to an embodiment of the present application. The communication system 100 includes a terminal device (represented as a UE in FIG1 ), a radio access network (represented as a next generation radio access network (NG-RAN) in FIG1 ), and a core network.

[0070] The radio access network includes one or more next-generation evolved node Bs (ng-eNBs) and gNBs. An ng-eNB represents an LTE base station connected to the 5G core network, and a gNB represents a 5G base station connected to the 5G core network. Communication between ng-eNBs, between two ng-eNBs, or between two gNBs occurs over the Xn interface. The Xn interface is also called the XnAP interface. The radio access network connects to the core network via the NG-C interface.

[0071] The core network includes other functions such as access and mobility management function (AMF) and location management function (LMF).

[0072] LMF is responsible for supporting different types of location services related to UE, including positioning of UE and transmission of auxiliary data to UE. LMF may exchange signals with RAN, such as ng-eNB or gNB, and UE. For example, LMF and ng-eNB or gNB exchange information through new radio positioning protocol annex (NRPPa) messages, such as obtaining configuration information of positioning reference signal (PRS), sounding reference signal (SRS), cell timing, cell location information, etc. For another example, LMF and UE transmit UE capability information, auxiliary information, measurement information, etc. through LTE positioning protocol (LPP) messages.

[0073] The AMF entity can receive location service requests related to the UE from the location services (LCS) entity of the 5G core network (5G core, 5GC), or the AMF itself can start some location services on behalf of a specific UE and forward the location service request to the LMF.

[0074] The terminal device connects to the radio access network via the ng-eNB via the LTE-Uu interface. The terminal device can also connect to the radio access network via the gNB via the NR-Uu interface.

[0075] It should also be understood that the communication system 100 may include one or more terminal devices, for example, one or more terminal device groups (such as the UE set shown in FIG1 ). A gNB may send data or control signaling to one or more terminal devices. Multiple gNBs may also simultaneously send data or control signaling to a single terminal device.

[0076] Optionally, the ng-eNB and gNB in ​​Figure 1 can also be replaced by TRP, TP, reception point (RP), cell, etc.

[0077] At present, deformation detection of objects is widely used in many fields, such as industrial safety, bridge and dam safety, construction, etc. Through deformation detection, potential safety issues can be discovered in a timely manner, maintenance can be carried out in a timely manner, and safety accidents can be avoided. Now, wireless base stations are widely deployed outdoors. Through the perception capabilities of wireless base stations, deformation detection can be achieved. Unlike traditional perception target detection, traditional perception capabilities detect unknown targets and obtain information such as the location and size of the target, while deformation detection is a long-term detection of specific targets to obtain information about the target's slight shape changes or displacement. For example, in this application, deformation can also be replaced by descriptions such as micro-deformation and displacement.

[0078] The basic principle of deformation detection is that a measuring station (base station or user end user) continuously transmits a fixed-phase signal, collects echo signals at different times, and then correlates the signals to determine the phase variation pattern. This phase variation can be converted into deformation. However, cellular network architectures do not support the detection and reporting of deformation information. Therefore, how to implement deformation detection of passive targets within the cellular network positioning framework and combine the characteristics of positioning has become an urgent problem.

[0079] In view of this, the present application proposes a method for sending measurement information, which can effectively solve the above technical problems. The method for sending measurement information proposed in the present application is described in detail below.

[0080] It is understandable that this application uses the first device and the second device as examples to illustrate the execution subjects of the interaction diagram, but this application does not limit the execution subjects of the interaction diagram. For example, the method executed by the first device in this application can also be executed by a module (such as a chip, a chip system, or a processor) applied to the first device, and can also be implemented by a logical node, a logical module or software that can realize all or part of the functions of the first device; the method executed by the second device in this application can also be executed by a module (such as a chip, a chip system, or a processor) applied to the second device, and can also be implemented by a logical node, a logical module or software that can realize all or part of the functions of the second device.

[0081] Fig. 2 is a schematic diagram of a method 200 for sending measurement information proposed in this application. The method 200 includes the following steps.

[0082] S210: The first device obtains first measurement information based on a first reference signal, where the first measurement information includes information of N coordinates, where the N coordinates are associated with a first path, and N is a positive integer.

[0083] It can be understood that since the N coordinates are associated with the first path, and information about the N coordinates is obtained based on the first reference signal, the first reference signal can also be considered to be associated with the first path. For example, the first reference signal being associated with the first path can specifically be transmitted on the first path.

[0084] Optionally, the first measurement information may also include one or more of the following other measurement information: delay-related measurement information, such as time of arrival (TOA), relative time of arrival (RTOA), reference signal time difference (RSTD), round-trip time (RTT), or Rx-Tx time difference, etc.; angle-related measurement information, such as angle of arrival (AoA) / direction of arrival (DoA), angle of departure (AoD), vertical angle of arrival (ZoA), vertical angle of departure (ZoD), etc.; phase-related measurement information, such as reference signal carrier phase (RSCP), reference signal carrier phase difference (RSCPD), phase, etc.; energy-related measurement information, such as reference signal received power (RSPD), reference signal carrier phase difference (RSTD), reference signal carrier phase difference (RSPD), phase, etc. power, RSRP), Reference signal received path power (RSRPP).

[0085] Optionally, the first path is associated with the first target. For example, the association between the first path and the first target may specifically be that the first target is located in the first path.

[0086] Optionally, the first measurement information is associated with the first path. For example, the first measurement information is measurement information of the first path measured based on the first reference signal.

[0087] Optionally, the N coordinates are associated with the first target. For example, the N coordinates are coordinate information of the first target obtained based on the first reference signal.

[0088] In this application, the first device acquiring the first measurement information based on the first reference signal can be understood as the first device acquiring the first measurement information based on the echo signal of the first reference signal. For example, the first reference signal encounters a first target during transmission along a first path, and generates an echo signal after refraction, reflection, or scattering on the surface of the first target. The first device receives the echo signal and acquires the first measurement information based on the echo signal.

[0089] S220: The first device obtains second measurement information based on the second reference signal, where the second measurement information includes information of M coordinates, where the M coordinates are associated with the first path, and M is a positive integer.

[0090] Similarly, since the M coordinates are associated with the first path, and information about the M coordinates is obtained based on the second reference signal, the second reference signal can also be considered to be associated with the first path. For example, the second reference signal being associated with the first path can specifically be transmitted on the first path.

[0091] Optionally, the second measurement information is associated with the first path. For example, the second measurement information is measurement information of the first path measured based on the first reference signal.

[0092] Optionally, the M coordinates are associated with the first target. For example, the M coordinates are coordinate information of the first target obtained based on the first reference signal.

[0093] Similarly, the first device obtains the second measurement information based on the second reference signal, which can also be understood as the first device obtaining the second measurement information based on the echo signal of the second reference signal.

[0094] For example, the first reference signal and the second reference signal can be one of reference signals such as a positioning reference signal (PRS), a sounding reference signal (SRS), a channel state information-reference signal (CSI-RS), a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a demodulation reference signal (DMRS), a perception signal, and a sounding signal. It should be understood that the above is only an example of the first reference signal and the second reference signal. The first reference signal and the second reference signal may also be other reference signals. This application does not specifically limit the first reference signal and the second reference signal.

[0095] It should be noted that in this application, the echo signals of the first reference signal and the second reference signal are received by the first device, but the first reference signal and the second reference signal can be sent by the first device or by other devices, and this application does not specifically limit this. For example, the first device can be a terminal device or a network device. The following example illustrates the reception and transmission of reference signal #1 (for example, the first reference signal or the second reference signal) and the sensing mode applicable to the embodiment of the present application.

[0096] As shown in Figure 3(a) and Figure 3(b), the transmitter of reference signal #1 and the receiver of its echo signal are the same device. Therefore, the corresponding sensing mode for this scenario is monostatic sensing mode. In Figure 3(a), the transmitter of reference signal #1 and the receiver of its echo signal are both base stations, while in Figure 3(b), the transmitter of reference signal #1 and the receiver of its echo signal are both terminal devices.

[0097] As shown in Figure 3(b), if the reference signal transmitter and the reference signal echo receiver are different devices, the corresponding sensing mode is called bistatic sensing mode. In Figure 3(c), the device transmitting reference signal #1 can be either terminal device #1 or base station #1, and the device receiving the reference signal echo can be either terminal device #2 or base station #2.

[0098] Optionally, before S210 and S220, the method further includes: the second device sending a request message to the first device, the request message requesting measurement, the measurement request associated with the first path. Correspondingly, the first device receives the request message from the second device. Furthermore, the measurement request associated with the first path indicates a request to measure a target associated with the first path (i.e., the first target).

[0099] Optionally, M may be equal to N, or M may not be equal to N.

[0100] Optionally, information on L coordinates in the M coordinate information is related to information on L coordinates in the N coordinate information, where L is a positive integer and is less than or equal to the minimum of N and M. For example, N=M=L, which means that the information on the M coordinates is related to the information on the N coordinates.

[0101] For example, the information of L coordinates in the information of M coordinates is correlated with the information of L coordinates in the information of N coordinates, which can be a one-to-one correspondence between the information of L coordinates in the information of M coordinates and the information of L coordinates in the information of N coordinates. For another example, the information of M coordinates is correlated with the information of N coordinates, which can be a one-to-one correspondence between the information of M coordinates and the information of N coordinates. It can be understood that the ultimate goal of this application is to characterize the deformation of the first target. Therefore, the following specifically describes how to characterize the deformation of the first target in combination with the information of N coordinates and the information of M coordinates. Two implementation methods of characterizing the deformation of the first target are given below as examples.

[0102] Implementation method 1: The information about N coordinates indicates N coordinates, and the information about M coordinates indicates M coordinates. For example, the coordinate types corresponding to the N coordinates and the M coordinates are Cartesian coordinates or polar coordinates. Examples are provided for different coordinate types.

[0103] In Example 1, N coordinates and M coordinates are three-dimensional Cartesian coordinates. Each of the N coordinates and the M coordinates consists of three real numbers (x, y, z), where (x, y, z) represents the distance of the point corresponding to the coordinate from the x-axis, y-axis, and z-axis, respectively.

[0104] In Example 1, the information of N coordinates can also be called the first point cloud information, and the information of M coordinates can also be called the second point cloud information. Here, the point cloud refers to a data set of points in a certain coordinate system. For example, the point cloud information includes the locations of multiple points, that is, the x, y, and z coordinates of multiple points in three-dimensional space. This is necessary information. Secondly, there can also be information such as color, light intensity, category label, normal vector, grayscale value, etc. This information is non-essential information and can be determined based on actual needs.

[0105] Based on Example 1, as shown in FIG4 , in the single-station sensing mode of the base station, the base station transmits a first reference signal. The first reference signal generates an echo signal after being refracted, reflected, or scattered on the surface of the first target. The first device receives the echo signal. At time #1, the base station obtains first point cloud information based on the echo signal. The coordinates corresponding to the first point cloud information are shown in FIG4 . Similarly, the base station transmits a second reference signal. The second reference signal generates an echo signal after being refracted, reflected, or scattered on the surface of the first target. The first device receives the echo signal. At time #2, the base station obtains second point cloud information based on the echo signal. The coordinates corresponding to the second point cloud information are shown in FIG4 . The first point cloud information and the second point cloud information include the same number of coordinates (i.e., M=N), and the coordinates included in the first point cloud information and the second point cloud information are correlated (e.g., the coordinates included in the first point cloud information and the second point cloud information correspond one-to-one). Therefore, after the first device transmits the first measurement information and the second measurement information to the second device in S230 , the second device can determine the deformation of the first target based on the N coordinates of the first point cloud information and the M coordinates of the second point cloud information. For example, the second device may obtain the deformation size of the first target by subtracting coordinate A from among the M coordinates and coordinate B from among the N coordinates, where coordinate A and coordinate B are corresponding coordinates.

[0106] Based on Example 1, the first point cloud information and the second point cloud information include different numbers of coordinates (i.e., M is not equal to N), and the L coordinates included in the first point cloud information and the L coordinates included in the second point cloud information are related (for example, the L coordinates included in the first point cloud information and the L coordinates included in the second point cloud information correspond one to one). Then, after the first device sends the first measurement information and the second measurement information to the second device in S230, the second device can determine the deformation amount of the first target based on the L coordinates included in the first point cloud information and the L coordinates included in the second point cloud information. For example, the second device can obtain the deformation size of the first target by subtracting coordinate A from the L coordinates of the first point cloud information from coordinate B from the L coordinates of the second point cloud information, where coordinate A and coordinate B are related coordinates.

[0107] Example 2: N coordinates and M coordinates are polar coordinates, then any coordinate among the N coordinates and the M coordinates consists of two real numbers (R, A), where R represents the distance between the point corresponding to the coordinate and the first device, and A represents the angle between the line between the point corresponding to the coordinate and the first device and the first reference line.

[0108] Optionally, in Example 2, R may also represent a distance-related measurement value, such as a time information measurement value, and the distance may be determined based on the distance-related measurement value. For example, R may represent round trip-time (RTT), Rx-Tx time difference, or arrival time.

[0109] In Example 2, the information of N coordinates can also be called the first set of range angle (RA) information, and the first set of RA information includes N RA information. The information of M coordinates can also be called the second set of RA information, and the second set of RA information includes N RA information. One RA information includes the distance information and angle information corresponding to one polar coordinate.

[0110] Optionally, the distance information and angle information in one RA message may be carried in different information or in the same information, which is not limited in this application.

[0111] Based on Example 2, as shown in Figure 5, in a single-station sensing mode, the base station transmits a first reference signal. The first reference signal generates an echo signal after refraction, reflection, or scattering on the surface of a first target. The first device receives the echo signal and, at time #1, obtains a first set of RA information based on the echo signal. The angle and distance in RA information #1 included in the first set of RA information are θ1 and d1, as shown in Figure 5. Similarly, the base station transmits a second reference signal to the first target and then receives the echo signal of the second reference signal. At time #2, the base station determines a second set of RA information based on the echo signal of the second reference signal. The angle and distance in RA information #2 included in the second set of RA information are θ2 and d2, as shown in Figure 5. Then, after the first device transmits the first measurement information and the second measurement information to the second device in S230, the second device can determine the deformation of the first target based on the N coordinates and the M coordinates. For example, the second device can obtain the deformation magnitude of the first target by subtracting coordinate A from the M coordinates from coordinate B from the N coordinates, where coordinates A and B are corresponding coordinates.

[0112] In a second implementation, the information about the N coordinates indicates the N coordinates, and the information about the M coordinates includes differential information about the M coordinates. Optionally, the coordinate types corresponding to the N coordinates and the M coordinates are Cartesian coordinates or polar coordinates. Examples are provided for different coordinate types.

[0113] Optionally, the differential information of the M coordinates is determined by the first device based on the first reference signal and the second reference signal. For example, the differential information of the M coordinates is obtained based on phase differential information between the first reference signal and the second reference signal.

[0114] It can be understood that in this implementation, N coordinates are used to describe the first target, and the differential information of the M coordinates is used to describe the deformation generated based on the first target described by the N coordinates.

[0115] Optionally, in the second implementation, the information of N coordinates indicates N coordinates, and the information of M coordinates indicates M differential coordinates corresponding to the M coordinates.

[0116] It can be understood that if M is equal to N, the N coordinates are related to the M differential coordinates; if M is not equal to N, the L coordinates in the N coordinates are related to the L differential coordinates in the M differential coordinates. Example 1, N coordinates are three-dimensional Cartesian coordinates, then any coordinate in the N coordinates consists of three real numbers (x, y, z), (x, y, z) respectively represent the distance of the point corresponding to the coordinate from the x-axis, y-axis and z-axis. The differential coordinate #i in the M differential coordinates is composed of three real numbers (Δxi, Δyi, Δzi), 1≤i≤M, where (Δxi, Δyi, Δzi) represents the offset relative to coordinate #i on the x-axis, y-axis and z-axis, and coordinate #i is the coordinate in the N coordinates corresponding to the differential coordinate #i.

[0117] In Example 1, the information of N coordinates may also be referred to as first point cloud information, and the information of M coordinates may also be referred to as differential point cloud information.

[0118] In Example 2, N coordinates are polar coordinates. Each of the N coordinates consists of two real numbers (R, A), where R represents the distance between the point corresponding to the coordinate and the first device, and A represents the angle between the line connecting the point corresponding to the coordinate and the first device and the first reference line. Among the M differential coordinates, differential coordinate #i consists of two real numbers (ΔRi, ΔAi), where 1≤i≤M, where (ΔRi, ΔAi) represents the offset in distance and angle relative to coordinate #i, and coordinate #i is the coordinate among the N coordinates corresponding to differential coordinate #i.

[0119] Optionally, in this implementation, the information of N coordinates indicates N coordinates, and the difference information of M coordinates indicates M difference distances corresponding to the M coordinates.

[0120] It can be understood that if M is equal to N, the N coordinates are associated with the M differential distances; if M is not equal to N, L coordinates out of the N coordinates are associated with L differential distances out of the M differential distances.

[0121] In Example 1, N coordinates are three-dimensional Cartesian coordinates. Each of these N coordinates consists of three real numbers (x, y, z), where (x, y, z) represents the distance from the corresponding point to the x-axis, y-axis, and z-axis, respectively. Among the M differential distances, differential distance #i is Δdi, where 1 ≤ i ≤ M. Δdi represents the distance offset relative to coordinate #i, and coordinate #i is the coordinate in the N coordinates associated with differential distance #i.

[0122] In Example 2, N coordinates are polar coordinates. Each of the N coordinates consists of two real numbers (R, A), where R represents the distance between the point corresponding to the coordinate and the first device, and A represents the angle between the line connecting the point corresponding to the coordinate and the first device and the first reference line. The value of differential distance #i among the M differential distances is Δdi, where 1≤i≤M. Δdi represents the distance offset relative to coordinate #i, and coordinate #i is the coordinate among the N coordinates associated with differential coordinate #i.

[0123] S230: The first device sends first measurement information and second measurement information to the second device. Correspondingly, the second device receives the first measurement information and the second measurement information from the first device, and the second device can determine the deformation of the target object based on the first measurement information and the second measurement information.

[0124] Optionally, the second device may be a network element related to positioning, for example, a LMF.

[0125] Optionally, the second device may be a network element related to perception. For example, the second device may be a sensing function (SF) network element.

[0126] Optionally, when the first device is an O-RAN device, this step may be performed by a first module in the first device. For example, the first module may directly send the first measurement information and the second measurement information to the second device, or may send the first measurement information and the second measurement information to a second module of the first device, which may then be directly or indirectly sent to the second device. The application does not impose any restrictions on this.

[0127] For example, when the first device is an O-RAN device, S210 and S220 can be implemented by RU, DU or CU, and S230 can be implemented by RU, DU or CU.

[0128] It should be noted that this application only uses the first measurement information and the second measurement information as an example for illustration. In actual applications, multiple measurement information can be obtained, and the deformation of the first target can be jointly characterized based on multiple sets of measurement information. This will not be repeated here.

[0129] It should be understood that the size of the serial numbers of the above processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
