[0003] In the field of environmental sensing, traditional methods typically rely on specialized sensors and equipment, such as cameras, radar, and infrared detectors. However, traditional methods have several drawbacks, including high cost, difficult deployment, and susceptibility to weather conditions.

[0004] With the continuous development of wireless communication technology, base stations, as core components of networks, are constantly expanding their functions and application scenarios. The technology of using base stations for environmental sensing is gradually gaining attention. This technology is based on the interaction between the base station and its surrounding environment, and achieves the perception and monitoring of the surrounding environment by collecting and analyzing signals received by the base station.

[0005] Among these applications, utilizing base stations to sense building deformation—for example, monitoring changes in buildings and historical structures within protected heritage sites—is of great significance in promptly identifying safety hazards caused by structural deformation. However, traditional object deformation detection requires the installation of targets (corner reflectors), which affects the structure and appearance of the object itself. Summary of the Invention

[0062] To facilitate understanding of the technical solutions provided in this application, the technical background involved in this application will be explained below.

[0063] Research has revealed the following advantages of using base stations for environmental sensing:

[0064] First, base stations have extensive coverage. As the infrastructure of wireless communication networks, base stations typically cover an entire city or a specific area. This means that using base stations for environmental sensing can enable real-time monitoring of large areas, providing valuable data support for urban planning, traffic management, disaster early warning, and other fields.

[0065] Secondly, base stations are characterized by continuous online operation. They need to provide communication services to users 24 hours a day, so they are always operational. This enables real-time, continuous data collection and analysis using base stations for environmental sensing, allowing for the timely detection and handling of environmental problems.

[0066] Furthermore, utilizing base stations for environmental sensing can reduce costs. Since base stations are already widely deployed in cities, there's no need to install a large number of additional sensors and equipment. Simply upgrading and modifying existing base stations is sufficient to achieve environmental sensing and monitoring. This not only saves significant investment costs but also avoids redundant construction and resource waste.

[0067] [Corrected from Detail 91, 02.07.2025] Currently, integrated sensing and communication (ISAC) technology based on the 5G-Advanced air interface achieves deep integration of communication and sensing services. Research on the application scenarios and potential needs of ISAC technology has been initiated within the 3rd generation partnership project (3GPP). Future application scenarios for ISAC systems in 6th generation (6G) mobile communication systems are likely to include ultra-high precision positioning, synchronous imaging, map building, and human sensory enhancement. In synchronous imaging, map building, and positioning application scenarios, these three sensing capabilities can mutually enhance each other. For example, imaging can capture images of the surrounding environment, positioning can obtain the locations of surrounding objects, and these images and locations can be used to build a map, which in turn improves location reasoning capabilities.

[0068] ISAC will leverage advanced algorithms, edge computing, and AI technologies to generate super-resolution, high-recognition images and maps. Vehicles, base stations, and other elements within these maps form a vast network, effectively utilizing sensors to significantly expand the imaging range. Furthermore, the imaging results can be easily fused and shared across the entire network via cloud services, significantly improving imaging performance. The 6G super-resolution and high-precision sensing capabilities support 3D indoor imaging and map building, enabling applications such as indoor scene reconstruction, spatial positioning, and indoor navigation, while providing the latest environmental information to the network and terminals. Object surfaces reflect signals like mirrors; precise map information can be used to determine multipath reflection points and reconstruct images of non-line-of-sight objects using mirroring technology. Therefore, after environmental reconstruction, the geometric prior information of the scene can be used for the localization and imaging of non-line-of-sight targets, enabling more accurate target location detection.

[0069] [Correction based on Rule 91, 02.07.2025] For a long time, wireless sensing has been an independently developed technology with little overlap with the development of mobile communication systems. Sensing services are provided by various specialized sensing devices, such as ordinary radar, lidar, computed tomography, and magnetic resonance imaging. In 5G and earlier communication systems, positioning was the only sensing service that mobile communication systems could provide. In 6G mobile communication systems, general sensing beyond positioning will be integrated into the communication system as a completely new function, thereby opening up entirely new services, such as high-precision positioning, environmental reconstruction, and gesture and action recognition.

[0070] Among these methods, the target area environment can be reconstructed using lasers, radar, base stations, and other means, which is to perceive and reconstruct the real physical environment. For example, based on measurement information, methods such as scattering polygons can be used to reconstruct the environment between the terminal and the base station, characterizing scattering objects such as walls and furniture within that area. However, current methods for detecting building deformation mainly rely on installing targets, which affects the building's structure and appearance.

[0071] Based on this, this application provides an object deformation sensing method, which senses whether a target object has undergone deformation through a base station and / or terminal, and reports the deformation indication without relying on a target.

[0072] In this application embodiment, a first device, a second device, and a third device are involved. The first device can be an access network device deployed in a radio access network to provide wireless communication functions for terminal devices; the second device is a core network device with sensing capabilities; and the third device can be a terminal device. Alternatively, the first device can be a terminal device, and the third device can be a device deployed in a radio access network to provide wireless communication functions for terminal devices.

[0073] Terminal equipment, also known as UE, mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises equipment (CPE), etc., refers to devices that include wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in vehicle-to-everything (V2X) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, or set-top boxes. The terminal device can also be a device or module that is connected to the communication system shown above and has corresponding communication functions. The terminal device usually contains a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0074] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the device or apparatus shown above; the specific application is not limited to any particular type.

[0075] Access network equipment is a device deployed in a radio access network to provide wireless communication functions for terminal devices. It can be referred to as an access network (RAN) entity, access node, network node, access network equipment, or communication device, etc.

[0076] Specifically, access network equipment can be access network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, fourth-generation (4G) mobile communication systems, 5G mobile communication systems, or 6G mobile communication systems.

For example, a next-generation Node B (gNB) in a new radio (NR) system, a transmission and reception point (TRP), a transmission and reception point (TP), or one or more antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, access network equipment can also be network nodes constituting a gNB or transmission point.

For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, access network equipment can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, in V2X technology, the access network equipment can be a roadside unit (RSU).

[0078] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), centralized unit control plane (CU-CP) can also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, centralized unit user plane (CU-UP) can also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations.

[0084] Figure 3 is a schematic diagram of a RAN chip structure provided in an embodiment of this application. As shown in Figure 3, a common RAN chip architecture is divided into CU, DU, and RU. The CU is a platform that performs upper-layer L2 and L3 functions. The Midhaul and Backhaul interfaces are used to carry traffic between the CU and DU, as well as between the CU and the core network. The DU performs L1 and some L2 functions, and the RU performs L1 calculation and RF digital part functions; the Fronthaul and Backhaul interfaces are used to carry traffic between the RU and DU, as well as between the CU and DU.

Similarly, the accelerator has a multi-channel high-speed serial computer expansion bus (PCIe) interface pointing to the CPU and external connections via Gigabit Ethernet (GbE) connectivity.

[0087] The RU comprises three parts: the OPU (O-RAN Processing Unit), which receives eCPRI frames from the O-RAN fronthaul and performs fronthaul interface, lowest-level L1 (encoding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The OPU can be implemented as a CPU, FPGA, or ASIC. The DPU (O-RU Digital Processing Unit) performs synchronization, DDC (digital downconversion in UL), DUC (digital upconversion in DL), CFR, and DPD, improving power amplifier efficiency by reducing PAPR / ACLR at the RF front-end; the DPU can be implemented as an FPGA or ASIC. The O-RU's RF processing unit includes a transceiver module, up / downconverters, power amplifiers (PA), low-noise amplifiers (LNA), and Tx / Rx filters. All conversions between the analog and digital domains (DAC and ADC) (e.g., RF sampling, frequency conversion using RF, IF, and LO mixing in upconversion and downconversion) are performed within the transceiver module. Note that physical and logical partitions within the RF processing unit do not require specific boundaries.

[0088] Referring to Figure 4, which is a schematic diagram of a baseband unit structure provided in an embodiment of this application, the baseband unit can be implemented using a processing system including one or more processors.

In other words, the processor used in the baseband can be used to implement the processes described below and any one or more of those processes.

[0089] A processing system can be implemented using a bus architecture, typically represented by a bus. A bus can include any number of interconnect buses and bridges, depending on the specific application and overall design constraints of the processing system. The bus communicatively couples various circuits together, including one or more processors (typically represented by a processor), memory, and computer-readable media (typically represented by a computer-readable media). The bus can also link various other circuits, such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further. The bus interface provides the interface between the bus and transceivers, and between the bus and the interface.

[0090] A transceiver provides a communication interface or means for communicating with various other devices via a wireless transmission medium. The transceiver may be coupled to an antenna array, and the transceiver and antenna array may be used together for communication with a corresponding network type. At least one interface (e.g., a network interface and / or a user interface) provides a communication interface or means for communication via an internal bus or via an external transmission medium.

[0091] The processor is responsible for managing the bus and general processing, including executing software stored on a computer-readable medium.

[0095] Referring to Figure 5a, which is a schematic diagram of a sensing network system architecture provided in an embodiment of this application, this architecture considers the addition of a sensing function (SF). The SF or location management function (LMF) can be combined, meaning sensing and positioning are handled by the same network element. The LMF is a core network element in the 5G core network (5GC) that provides control plane positioning. It completes the calculation and feedback of location information in the 5G network, providing functions such as positioning process management, terminal capability acquisition, auxiliary data provision, and terminal location estimation. Specifically, it provides the following functions: supporting UE location calculation; obtaining downlink location measurements or location estimates from the UE; and obtaining uplink location measurements from the NG RAN.

[0096] In this architecture, the SF can reuse the interfaces between the LMF and other 5GC network elements such as the Access and Mobility Management Function (AMF), Network Exposure Function (NEF), Unified Data Management (UDM), Network Data Analytics Function (NWDAF), and Policy Control Function (PCF) for perception interaction. Perception control signaling between the LMF (including the SF) and the Radio Access Network (RAN) 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 LTE Positioning Protocol (LPP) or NR Positioning Protocol Annex (NRPPa) protocols, or it can be transmitted via the user plane, using the User Plane Function (UPF) for forwarding or direct transmission to the LMF (including the SF).

[0097] 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 the Gateway Mobile Location Center (GMLC) 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 performing LMF selection, etc.

[0098] The sensing network element SF sets up interfaces and interacts with 5GC network elements such as AMF, NEF, UDM, NWDAF, PCF, LMF, and UPF. The specific definitions are as follows:

[0099] NS1: A new NS1 interface is added between the sensing network element and the AMF. This 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.

[0100] NS2: A new NS2 interface is added between the sensing network element and NEF. This interface can transmit signaling messages between the sensing network element and the service-side application function (AF) through NEF, and at the same time open the sensing results to the AF.

[0101] NS3: A new NS3 interface is added between the sensing network element and the UDM. Through this interface, authentication or authorization can be achieved, and UE sensing subscription information, service AMF information or other information can be obtained.

[0102] NS4: A new NS4 interface is added between the sensing network element and the NWDAF. Through this interface, the sensing network element and the NWDAF can jointly complete artificial intelligence (AI) processing related to sensing services.

[0103] NS5: A new NS5 interface is added between the sensing network element and the PCF. Through this 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. The PCF then makes decisions to generate PCC policies related to the sensing service.

[0104] NS6: A new NS6 interface is added between the sensing network element and the LMF. Through this 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.

[0105] NS7: The NS7 interface is added to the sensing network element and user plane function. Sensing measurement data can be directly transmitted to the sensing network element via the (R)AN through the user plane function, or it can be indirectly forwarded to the sensing network element via the UPF. If the (R)AN performs sensing in the scenario and forwards the data via the UPF, the UPF needs to be modified to support the data transmission at the (R)AN granularity.

[0106] 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.

[0107] 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:

[0108] N33: This is the interface between AF and NEF. Through this interface, the sensing business type, business requirements, sensing results, etc. can be transmitted.

[0109] NL5: This is the interface between NEF and GMLC. Information such as the type of sensing service, service requirements, and sensing results can be transmitted through this interface.

[0110] NL6: This is the interface between GMLC and UDM, through which privacy inspection data can be transmitted;

[0111] NL2: This is the interface between NEF and AMF. Through this interface, information such as the type of sensing business, business requirements, and sensing results can be transmitted.

[0112] NL1: This is the interface between AMF and LMF, through which the sensing service type, service requirements, sensing results, etc. can be transmitted.

[0113] 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.

[0114] Referring to Figure 5b, this figure is a schematic diagram of another sensing network architecture provided by an embodiment of this application. In this architecture, the sensing function is relatively independent from the existing 5GC, and the sensing network elements do not need to interact with the 5GC or only perform minimal interaction. For scenarios where there is only a sensing need in a specific area or only a sensing need, this architecture can provide sensing services without the need for 5GC control or with only some network elements participating in control. It can also achieve sensing measurement data or sensing results not leaving the campus through SF localization deployment, thereby meeting the enterprise's needs for the security and privacy of sensing measurement data or sensing results, and reducing sensing latency. This architecture is simple, flexible, efficient, has few transmission nodes, is easy to deploy, and can optionally support UE-related sensing needs, considering the implementation schemes of functions such as authorization, mobility management, and billing as needed.

[0115] In this architecture, the SF directly connects to the RAN node, and both sensing control plane signaling messages and sensing measurement data are transmitted via the newly defined interface NS1. When the UE participates in sensing, control plane signaling messages are forwarded to the SF through the AMF, and sensing measurement data is transmitted via NS1. In addition, the SF may also have interfaces with 5GC network elements AMF, NEF, or NWDAF to ensure that the AF must provide sensing service requirements to the SF through core network functions.

[0116] NS1: An NS1 interface is added between the sensing network element and the (R)AN. This interface transmits sensing control signaling or sensing measurement data. In one deployment implementation, the sensing function can also be deployed at the base station.

[0117] NS2: A new NS2 interface may be added between the sensing network element and the AMF. This interface receives sensing service requests from the UE or transmits signaling messages between the sensing network element and other core network elements, such as interaction messages with the UDM.

[0118] NS3: A new NS3 interface may be added between the sensing network element and NEF. This interface transmits signaling messages that the sensing network element interacts with the service-side AF through NEF, and at the same time exposes the sensing results to the AF. The interaction between the sensing function and the AF may not go through NEF. In actual deployment, NS2 and NS3 will be selected. That is, the AF sends sensing service requests to the SF indirectly or directly to the SF (without NEF) through NS2 (NEF); or, the AF sends sensing service requests to the SF through N33 (NEF) and NS2 (AMF).

[0119] NS4: A new NS4 interface may be added between the sensing network element and the NWDAF. Through this interface, the sensing network element and the NWDAF will jointly perform intelligent analysis and prediction to generate sensing results.

[0120] In the embodiments of this application, the second device is a device with sensing function, such as an SF, an AMF (including SF), or an LMF (including SF). In this application, the specific form of the second device is not limited.

[0121] The technical solution provided in this application will be described below with reference to specific embodiments. For ease of understanding, the description will be based on either the first device being a base station and the third device being a terminal device, or the first device being a terminal device and the third device being a base station.

[0122] Referring to Figure 6, which is an interactive diagram of an object deformation detection method provided in an embodiment of this application, as shown in Figure 6, the method includes:

[0123] S601: The second device sends a measurement request to the first device.

[0124] In this application, a second device with sensing capabilities sends a measurement request to a sensing device (i.e., the first device) to determine whether a target object has deformed. This measurement request includes reference shape information of the target object. The target object can be any object with a three-dimensional structure, such as a building. The reference shape information can include information about different dimensions of the target object, such as height, width, and length, and can also include the target object's position information. Specifically, this position information can be the world coordinates or latitude and longitude coordinates of each vertex of the target object in three-dimensional space.

[0125] When the first device is an access network device and the second device is a core network device, the second device can directly send a measurement request to the first device via the backhaul link. When the first device is a UE (User Equipment) and the second device is a core network device, the core network device can send a measurement request to the UE through the access network device. For example, as shown in Figure 1, the core network device sends a measurement request to the access network device via the backhaul link, which is processed by the access network device's baseband unit (BBU). In the BBU, the control unit (CU) sends the measurement request to the distributed unit (DU) via the midhaul link, and then the DU sends it to the radio frequency unit (RU) via the forward pass link. The RU sends the measurement request to the UE via the air interface. The DU and RU can be co-located or non-co-located. Specifically, in the RAN chip, as shown in Figure 3, the DU sends the measurement request to the RU via the eCPRI interface, and then the RU sends it to the UE via the air interface.

[0126] It should be noted that, in this embodiment, the first device refers to the device that needs to sense the reference signal and then determine whether the target object has undergone deformation based on the sensed signal. The device sending the reference signal can be either the first device or a third device. Based on this, possible sensing methods in this application include base station transmission / reception, UE transmission / reception, base station transmission / UE reception, and UE transmission / UE reception; each sensing method will be described subsequently.

[0127] S602: The first device acquires the sensing result based on the reference shape information and the sensing signal.

[0128] The sensed signal refers to the signal that is reflected, diffracted, or scattered by the target object after a reference signal is sent by the first or third device. For ease of understanding, reflection will be used as an example in the following explanation.

[0129] In this application, after the first device or the third device sends a reference signal, the first device can receive signals reflected by each object. In this case, the first device can determine the sensing signal reflected by the target object from the received signals based on the reference shape information, so as to use the sensing signal to determine whether the target object has changed, i.e., to obtain the sensing result.

[0130] The first device obtains the sensing result based on the reference shape information and the sensing signal, which may include the following implementation methods:

[0131] One method involves the first device determining a first sensing signal from the received signals based on reference shape information, and using this first sensing signal to reconstruct the target object, obtaining reconstructed shape information. The reference shape information and the reconstructed shape information are then compared to determine whether the target object has deformed. In other words, it determines whether the reference shape and the actual reconstructed shape are the same; if they are the same, no deformation has occurred; if they are different, deformation has occurred. The first sensing signal refers to the signal reflected by the target object and sensed by the first device after the first or third device sends a first reference signal. Using this method, if the target object deforms, the deformation amount in certain dimensions can also be determined, such as changes in height or width.

[0132] Another approach involves, after acquiring the reconstructed shape information, if it's a self-transmitting and self-receiving system, the first device can determine the parameter values ​​for transmitting a specific beam (second reference signal) based on the reconstructed shape information. The first device then transmits the second reference signal according to these parameter values ​​and receives the second sensing signal, determining the sensing result based on the second sensing signal. If it's not a self-transmitting and self-receiving system, the first device can send either the reconstructed shape information or the parameter values ​​of the second reference signal to the third device. If the third device receives the reconstructed shape information, it determines the parameter values ​​for transmitting the second reference signal based on that information and then transmits the second reference signal. If the third device receives the parameter values ​​of the second reference signal, it directly transmits the second reference signal based on those parameter values.

[0133] The specific implementation of the first device determining the sensing result based on the second sensing signal will be described in subsequent embodiments.

[0134] S603: The first device sends the sensing results to the second device.

[0135] Specifically, when the perception result indicates that the target object has undergone deformation, the perception result may also include the target dimension, which indicates that the target object has undergone deformation along that target dimension. Furthermore, to determine the scale of change in the target dimension, the perception result may also include the deformation amount corresponding to that target dimension.

[0136] In practical implementation, the perception result can be a 1-bit indication information, which is used to indicate that the target object has undergone deformation.

[0137] When the first device is an access network device and the second device is a core network device, the first device can directly send the sensing results to the second device. When the first device is a UE and the second device is a core network device, the first device can send the sensing results to the second device through the access network device. For example, in the application scenario shown in Figure 1, the UE transmits the data to the radio frequency unit RU through the air interface, and then the RU sends it to the DU through the fronthaul link. The DU transmits it to the CU through the midhaul link, and then the CU sends it to the core network device CN through the backhaul link. The transmission of the sensing results is performed at layer 3, and the DU and RU can cooperate to implement the functions of the PHY layer. One DU can be connected to one or more RUs, and the functions of the DU and RU can be configured according to the actual application scenario. Specifically, in the RAN chip, as shown in Figure 3, the RU sends the sensing results to the DU through the eCPRI interface, and then sends them to the core network CN through the CU.

[0138] As can be seen, base stations or terminals can sense the deformation of target objects based on reference shape information sent by sensing network elements and signals reflected by the target objects, without the need to install targets, thus avoiding the impact on the appearance and structure of target objects.

[0139] Based on the above method embodiments, to further illustrate the process of sensing object deformation, please refer to Figure 7. This figure is an interactive diagram of an object deformation detection method provided in this application embodiment. As shown in Figure 7, the method includes:

[0140] S701: The second device sends a measurement request to the first device.

[0141] S702: The first device determines the first sensing signal based on the reference shape information in the measurement request, and uses the first sensing signal to reconstruct the target object to obtain the reconstructed shape information.

[0142] In this embodiment, if it is a self-transmitting and self-receiving sensing method, the first device will send a first reference signal and simultaneously receive a sensing signal after receiving a measurement request. This sensing signal may include signals arriving via direct transmission, or signals arriving after reflection, scattering, or other means by the target object. Since this application aims to detect whether the target object has undergone deformation, it is necessary to determine the sensing signal related to the target object from the acquired sensing signal, i.e., the signal after reflection, diffraction, or scattering by the target object.

[0143] Based on this, the first device determines a first sensing signal from the received sensing signals according to the reference shape information, so as to reconstruct the target object using the first sensing signal and obtain the reconstructed shape information. The transmission path corresponding to the first sensing signal is the transmission path related to the target object, i.e., the target transmission path.

[0144] Specifically, after determining the target transmission path, the target object can be reconstructed based on the target transmission path and the reference point location to obtain the reconstructed shape information. The reference point location can be the location of the first device or the location of the third device. For example, in a scenario where the base station transmits and receives data independently, for areas that the base station cannot perceive, given some prior knowledge of the target object's horizontal position (i.e., obtaining reference shape information), the approximate shape of the target object can be reconstructed by combining the fuzzy position of the terminal device (which contains a certain positional error).

[0145] The process of reconstructing the target object based on the target transmission path and the location of the first or third device includes:

[0146] The channel estimate of the target transmission path is obtained based on the first sensing signal. Point cloud data of the target object is determined based on this channel estimate and the location of the reference point. The target object is then reconstructed based on this point cloud data to obtain reconstructed shape information. This reconstructed shape information may include different dimensions of the target object, such as height, width, and length, and may also include the target object's position information.

[0147] S703: The first device receives the second sensing signal and determines the sensing result based on the second sensing signal.

[0148] In this embodiment, after obtaining the reconstructed shape information, the parameter values ​​of the second reference signal to be transmitted can be determined based on the reconstructed shape information, and then the second reference signal is transmitted according to the parameter values. Subsequently, the first device receives the second sensing signal corresponding to the second reference signal and determines the sensing result based on the second sensing signal. This sensing result is used to indicate whether the target object has undergone deformation. The second sensing signal refers to the signal perceived by the first device after reflection, scattering, and diffraction by the target object following the transmission of the second reference signal by the first device or the third device. That is, the second sensing signal is also a signal related to the target object. The second reference signal is used for detecting the deformation of the target object.

[0149] In this embodiment, after receiving the sensing signal, the first device can determine the second sensing signal from the received sensing signal based on the reconstructed shape information. That is, it determines which of the received sensing signals are signals reflected, scattered, or diffracted by the target object based on the reconstructed shape information.

[0150] In a self-receiving sensing scenario, after obtaining the reconstructed shape information, the first device determines the parameter value of the second reference signal to be sent based on the reconstructed shape information, and then sends the second reference signal according to the parameter value.

[0151] In non-spontaneous sensing scenarios, after obtaining the reconstructed shape information, the first device determines the parameter values ​​of the second reference signal to be transmitted based on the reconstructed shape information, and sends these parameter values ​​to the third device so that the third device can transmit the second reference signal according to the parameter values. Alternatively, the first device sends the reconstructed shape information to the third device, which then determines the parameter values ​​of the second reference signal to be transmitted based on the reconstructed shape information and transmits the second reference signal according to the parameter values.

[0152] The second reference signal can be used to detect deformation in a certain dimension of the target object, such as detecting the height of the target object. Therefore, when determining parameter values ​​based on the reconstructed shape information, the second reference signal corresponding to that parameter value is a reference signal capable of detecting deformation in that dimension. For example, if deformation detection is performed on the height of the target object, the vertical angle of the second reference signal is related to that height (the height in the reconstructed shape information); if deformation detection is performed on the width of the target object, the horizontal angle of the second reference signal is related to that width (the width in the reconstructed shape information).

[0153] Specifically, determining the perception result based on the second sensing signal includes: determining the signal energy corresponding to the second sensing signal; determining whether the signal energy is greater than a threshold; if it is greater than the threshold, then determining that the target object has undergone deformation. Specifically, if the second reference signal is a reference signal for the target dimension of the target object, determining the signal energy of the second sensing signal in the target dimension; if the signal energy is greater than the threshold, then determining that the target object has undergone deformation in that target dimension.

[0154] For example, to detect whether the height of a target object has changed, the base station or terminal forms a beam (vertical beam) targeting that height. If the energy of the beam reflected by the target object in the vertical direction is greater than a threshold, then the target object is considered to have a height deformation. As another example, to detect whether the width of a target object has changed, the base station or terminal forms a beam (horizontal beam) of a specific width. If the energy of the beam reflected by the target object in the horizontal direction is greater than a threshold, then the target object is considered to have a width deformation.

[0155] S704: The first device sends the sensing results to the second device.

[0156] As can be seen, the first device sends a measurement request to the second device, requesting the second device to sense the deformation of the target object. This measurement request includes reference shape information of the target object, such as its height. The second device determines a first sensing signal from multiple received sensing signals based on the reference shape information, and reconstructs the target object based on this first sensing signal to obtain reconstructed shape information. This first sensing signal refers to the signal sensed by the first device after a reference signal is sent by the first device itself or a third device, and is reflected, scattered, or diffracted by the target object. That is, the first sensing signal is a signal related to the target object. The first device or the third device sends a reference signal for the target object in a certain dimension. After sensing a second sensing signal, which is a reflection, scattering, or diffracted by the target object, the first device determines a sensing result based on the second sensing signal. This sensing result indicates whether the target object has deformed. The parameter value of the reference signal corresponding to the second sensing signal is determined based on the reconstructed shape information. In other words, the technical solution provided in this application allows for deformation detection of the target object based on the reference shape information sent by the second device, eliminating the need for a target and avoiding any impact on the appearance and structure of the target object.

[0157] To facilitate understanding of the technical solution of this application, please refer to the application scenario diagrams shown in Figures 8a and 8b. The specific implementation for this application scenario includes:

[0158] (1) SF sends a measurement request to the base station, which includes reference shape information of the target building, such as height information.

[0159] (2) The base station determines the transmission path related to the target building based on the reference shape information, and determines certain faces of the target building that cannot be perceived by the base station (such as the right facade in Figure 8a) based on the terminal location (which has some errors) and the parameters of the transmission path, thereby reconstructing the shape of the target building.

[0160] (3) When performing height deformation detection on a target building, beam scanning at a specific height is performed using reconstructed shape information to detect changes in the target building's height. Specifically, a beam targeting a specific height of the target building is formed based on the reconstructed shape information, and the corresponding height is detected. If the height of the reflected beam (which refers to the energy of the beam in the vertical direction) is greater than a threshold, it is determined that the target building has undergone height deformation. For example, as shown in Figure 8b, the horizontal axis represents time and the vertical axis represents the signal energy value. The energy of the sensed signal received at time t4 is relatively large, exceeding the threshold, thus determining that height deformation has occurred.

[0161] The following will explain the different sensing methods in conjunction with the accompanying drawings.

[0162] Referring to Figure 9, which is a flowchart of the base station's self-transmitting and self-receiving deformation detection of a target object, this detection method is illustrated using the base station as the first device and the SF as the second device as an example, as shown in Figure 9:

[0163] S901: SF interacts with the base station to obtain sensing capability information in order to determine whether the base station has sensing capabilities.

[0164] S902: SF sends a measurement request to the base station to request the base station to perform deformation detection on the target object.

[0165] The measurement request includes reference shape information of the target object, such as the height, length, width, and position information of the target object.

[0166] S903: The base station sends a reference signal and receives the sensing signal corresponding to the reference signal, and determines the signal energy on the reference signal reflected by the target object based on the reference shape information and the sensing signal.

[0167] In a scenario where the base station transmits and receives signals independently, the base station first transmits a first reference signal. Based on the reference shape information, it determines the first sensing signal from the received sensing signals and reconstructs the target object using this first sensing signal to obtain reconstructed shape information. Then, based on the reconstructed shape information, it transmits a specific beam targeting the target object, i.e., a second reference signal, and determines the signal energy based on the received second sensing signal. The second sensing signal is the reference signal reflected by the target object and received by the base station.

[0168] It should be noted that when the specific beam transmitted is used to detect the deformation of a target object in a certain latitude, the determined signal energy is the signal energy for that dimension.

[0169] S904: The base station determines whether the target object has deformed based on the signal energy and obtains the sensing results.

[0170] After acquiring the signal energy, the base station determines whether the signal energy is greater than a threshold. If it is, it determines that the target object has deformed; otherwise, it determines that the target object has not deformed.

[0171] If the second reference signal is used to detect whether the target object has deformed in a certain dimension, if the energy value of the signal reflected by the target object is greater than the threshold, it is determined that the target object has deformed in that dimension.

[0172] The specific implementation of the base station for target object deformation detection can be found in the relevant descriptions in the embodiments shown in Figure 6 or Figure 7 above, and will not be repeated here.

[0173] S905: The base station sends the sensing results to SF.

[0174] The perception result is used to indicate whether the target object has undergone deformation. For a detailed description of the specific manifestation of the perception result, please refer to the relevant description in the embodiment shown in Figure 7.

[0175] Referring to Figure 10, which is a flowchart of the UE's self-transmitting and self-receiving deformation detection of the target object, as shown in Figure 10, this detection method is illustrated using the UE as the first device and the SF as the second device as an example.

[0176] S1001: SF interacts with UE to obtain perception capability information in order to determine whether UE has perception capability.

[0177] S1002: SF sends a measurement request to UE to request UE to perform deformation detection on the target object.

[0178] The measurement request includes reference shape information of the target object, such as the height, length, width, and position information of the target object.

[0179] S1003: The UE sends a reference signal and receives a sensing signal corresponding to the reference signal, and determines the signal energy of the reference signal reflected by the target object based on the reference shape information and the sensing signal.

[0180] In a scenario where the UE transmits and receives signals independently, the UE first transmits a first reference signal and determines the first sensing signal from the received sensing signals based on the reference shape information. It then reconstructs the target object based on this first sensing signal to obtain the reconstructed shape information. Next, based on the reconstructed shape information, it transmits a specific beam targeting the target object, namely a second reference signal, and determines the signal energy based on the received second sensing signal.

[0181] It should be noted that when the specific beam transmitted is used to detect the deformation of a target object in a certain latitude, the determined signal energy is the signal energy for that dimension.

[0182] S1004: The UE determines whether the target object has deformed based on the signal energy and obtains the perception result.

[0183] After obtaining the parameter value of the signal energy, the UE determines whether the signal energy is greater than the threshold. If it is, it determines that the target object has deformed; otherwise, it determines that the target object has not deformed.

[0184] If the second reference signal is used to detect whether the target object has deformed in a certain dimension, if the energy value of the signal reflected by the target object is greater than the threshold, it is determined that the target object has deformed in that dimension.

[0185] The specific implementation of the UE for target object deformation detection can be found in the relevant descriptions in the embodiments shown in Figure 6 or Figure 7 above, and will not be repeated here.

[0186] S1005: The UE sends the sensing results to the SF.

[0187] The perception result is used to indicate whether the target object has undergone deformation. For details on the specific manifestation of the perception result, please refer to the relevant descriptions in the embodiments shown in Figure 6 or Figure 7.

[0188] Referring to Figure 11, this figure is a flowchart of the deformation detection of a target object by the base station transmitting and the UE receiving data. As shown in Figure 11, this detection method is illustrated using the UE as the first device, the SF as the second device, and the base station as the third device as an example.

[0189] S1101: SF interacts with the base station and UE to obtain sensing capability information in order to determine whether the base station and UE have sensing capabilities.

[0190] S1102: SF sends a measurement request to UE to request UE to detect the deformation of the target object.

[0191] The SF can send a measurement request to the UE via the base station, or the SF can send the measurement request directly to the UE. This measurement request includes reference shape information of the target object, such as the object's height, length, width, and location.

[0192] S1103: The base station sends a reference signal to the UE.

[0193] S1104: The UE receives the sensing signal corresponding to the reference signal and determines the signal energy of the reference signal reflected by the target object based on the reference shape and the sensing signal.

[0194] The process of the base station sending a reference signal to the UE includes the base station sending a first reference signal to the UE, enabling the UE to determine a first sensing signal based on reference shape information, and to reconstruct the target object based on the first sensing signal to obtain reconstructed shape information. It may also include the base station sending a second reference signal to the UE, and the UE determining the signal energy based on the received second sensing signal.

[0195] Since the parameter values ​​of the second reference signal are determined based on the reconstructed shape information, after the UE determines the reconstructed shape information of the target object, it can send the reconstructed shape information to the base station, which will then send a specific beam, i.e., the second reference signal, to detect the deformation of the target object based on the reconstructed shape information.

[0196] S1105: The UE determines whether the target object has deformed based on the signal energy and obtains the perception result.

[0197] After acquiring the signal energy, the UE determines whether the signal energy is greater than a threshold. If it is, it determines that the target object has deformed; otherwise, it determines that the target object has not deformed.

[0198] The specific implementation of the UE for target object deformation detection can be found in the relevant descriptions in the embodiments shown in Figure 6 or Figure 7 above, and will not be repeated here.

[0199] S1106: The UE sends the sensing results to the SF.

[0200] The perception result is used to indicate whether the target object has undergone deformation. For details on the specific manifestation of the perception result, please refer to the relevant descriptions in the embodiments shown in Figure 6 or Figure 7.

[0201] Referring to Figure 12, this figure is a flowchart of the deformation detection of a target object by the UE transmitting and receiving base station. As shown in Figure 12, this detection method is illustrated using the base station as the first device, the SF as the second device, and the UE as the third device as an example.

[0202] S1201: SF interacts with the base station and UE to exchange sensing capability information in order to determine whether the base station and UE have sensing capabilities.

[0203] S1202: SF sends a measurement request to the base station to request the base station to detect the deformation of the target object.

[0204] The measurement request includes reference shape information of the target object, such as the height, length, width, and position information of the target object.

[0205] S1203: The base station sends relevant configuration information about the reference signal to the UE so that the UE can send the reference signal.

[0206] S1204: The base station receives the sensing signal corresponding to the reference signal, and determines the signal energy of the reference signal reflected by the target object based on the reference shape information and the sensing signal.

[0207] In this embodiment, upon receiving a measurement request from the SF, the base station configures relevant parameters for the reference signal for the UE, enabling the UE to transmit the reference signal based on these parameters. During this process, the UE transmits a first reference signal. The base station determines a first sensing signal based on the reference shape information and reconstructs the target object using the first sensing signal to obtain the reconstructed shape information.

[0208] The base station determines the relevant parameter values ​​of the second reference signal to be transmitted based on the reconstructed shape information, and sends these parameter values ​​to the UE so that the UE can transmit the second reference signal according to these parameter values. The base station receives the second sensing signal reflected, scattered, or diffracted by the target object, and determines the signal energy of the reference signal reflected by the target object based on the second sensing signal.

[0209] S1205: The base station determines whether the target object has deformed based on the signal energy and obtains the sensing result.

[0210] After acquiring the signal energy, the base station determines whether the signal energy is greater than a threshold. If it is, it determines that the target object has deformed; otherwise, it determines that the target object has not deformed.

[0211] The specific implementation of the base station for target object deformation detection can be found in the relevant descriptions in the embodiments shown in Figure 6 or Figure 7 above, and will not be repeated here.

[0212] S1206: The base station sends the sensing results to SF.
