[0033] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0034] Communication system architecture

[0035] Figure 1 is a system architecture example diagram of a wireless communication system 100 to which embodiments of this application can be applied. The system architecture shown in Figure 1 may include terminal equipment, access network (AN) equipment, and network elements in the core network.

[0036] It should be understood that the technical solutions of the embodiments of this application can be applied to various communication systems, such as: 5th generation (5G) systems or new radio (NR), long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to future communication systems, such as 6th generation mobile communication systems, satellite communication systems, and so on.

[0037] The terminal device in this application embodiment can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), MT, remote station, remote terminal, mobile device, user terminal, terminal, wireless terminal, user agent, or user device. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. The terminal devices in the embodiments of this application can be 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, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a dispatching entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) communications. For example, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.

[0038] Access network equipment refers to devices that allow terminal devices to wirelessly access the network architecture. They are primarily responsible for air interface-side radio resource management, Quality of Service (QoS) management, data compression, and encryption. Access network equipment can also be called radio access network (RAN) equipment, such as base stations. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master eNB (MeNB), secondary eNB (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar entities, or combinations thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. A base station can also be a mobile switching center, a device that performs base station functions in D2D, V2X, and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. A base station can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the access network equipment.

[0039] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0040] In some deployments, the access network device in this application embodiment may refer to a CU or a DU, or the access network device may include both a CU and a DU. The gNB may also include an AAU.

[0041] The types of network elements in the core network can include user plane function (UPF) network elements, access and mobility management function (AMF) network elements, session management function (SMF) network elements, policy control function (PCF) network elements, data network (DN), network slice selection function (NSSF), authentication server function (AUSF), unified data management (UDM), network exposure function (NEF), network repository function (NRF), and network slice-specific authentication and authorization function (NSSAAF). Among these, UPF network elements are primarily responsible for user data transmission. The other network elements, which can be referred to as control plane function network elements, are mainly responsible for authentication, authorization, registration management, session management, mobility management, and policy control to ensure reliable and stable transmission of user data.

[0042] UPF network elements can be used to forward and receive data from terminal devices. For example, a UPF network element can receive service data from the data network and transmit it to the terminal device through the access network equipment; a UPF network element can also receive user data from the terminal device through the access network equipment and forward it to the data network. The transmission resources allocated and scheduled by the UPF network element for the terminal device are managed and controlled by the SMF network element. The bearer between the terminal device and the UPF network element can include: the user plane connection between the UPF network element and the access network equipment, and the channel established between the access network equipment and the terminal device. The user plane connection is a QoS flow that can be established between the UPF network element and the access network equipment for transmitting data.

[0043] AMF network elements can be used to manage terminal device access to the core network, such as: terminal device location updates, network registration, access control, terminal device mobility management, and terminal device attachment and detachment. When providing services for a terminal device's session, AMF network elements can also provide control plane storage resources for that session to store session identifiers and the associated SMF network element identifiers.

[0044] SMF network elements can be used to select user plane network elements for terminal devices, redirect user plane network elements for terminal devices, assign Internet Protocol (IP) addresses to terminal devices, establish bearers (also known as sessions) between terminal devices and UPF network elements, modify and release sessions, and perform QoS control.

[0045] PCF network elements are used to provide policies to AMF and SMF network elements, such as QoS policies and slice selection policies.

[0046] DN (Network Node) can provide data services to users for networks such as IP Multimedia Service (IMS) and the Internet. Within a DN, there can be various application servers (AS) providing different application services, such as carrier services, Internet access, or third-party services. AS can implement application functions (AFs). AF elements are used to interact with network elements in the 3GPP core network to support application-affected data routing, access network exposure functions, and interact with PCF (Policy Control Function) elements for policy control, etc.

[0047] NSSF is used for network slice selection and supports the following functions: selecting a set of network slice instance examples to serve the end device; determining allowed network slice selection assistance information (NSSAI), and, when necessary, determining the mapping to the subscribed single-network slice selection assistance information (S-NSSAI); determining the configured NSSAI, and, when necessary, determining the mapping to the subscribed S-NSSAI; determining the set of AMFs that may be used to query the end device, or determining a list of candidate AMFs based on the configuration.

[0048] AUSF is used to receive AMF requests for authentication of terminal devices. It requests a key from UDM and then forwards the issued key to AMF for authentication processing.

[0049] UDM includes functions such as generating and storing user subscription data and managing authentication data, and supports interaction with external third-party servers.

[0050] NEF is used for capability exposure, meaning that based on NEF, network capabilities can be exported to external networks. Untrusted external applications can access core network data through NEF to ensure network security. NEF can provide functions such as QoS capability exposure for external applications, event subscription, and AF request distribution.

[0051] The Network Request Forwarder (NRF) is used for the registration, management, and status detection of network elements in the core network, thereby achieving automated management of these elements. When a network element in the core network starts up, it must register with the NRF before it can provide services. Registration information may include, for example, the network element's type, address, and service list.

[0052] In addition, some networks (such as 5G networks) have added network data analytics function (NWDAF) to the core network. Based on NWDAF, data can be collected from various network elements and network management systems in the core network, and big data statistics, analysis or intelligent data analysis can be performed to obtain network-side analysis or prediction data, thereby assisting various network elements to more effectively control terminal device access based on the data analysis results.

[0053] In some communication systems (such as 5G and 6G systems), network elements in the core network can also be called network functions (NFs).

[0054] It should be noted that each network element in Figure 1 can be a network component in a hardware device, a software function running on dedicated hardware, or a virtualization function implemented on a platform (e.g., a cloud platform). It should also be noted that the network architecture shown in Figure 1 is merely an illustrative representation of the network elements included in the overall network architecture. In this embodiment, the network elements included in the overall network architecture are not limited.

[0055] Those skilled in the art will understand that the network architecture shown in Figure 1 does not constitute a limitation on the network architecture. In specific implementations, the network architecture may include more or fewer network elements than shown in the figure, or combine certain network elements, etc. It should be understood that AN or RAN is represented in Figure 1 as (R)AN.

[0056] In some scenarios, network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenarios in which the network devices and terminal devices are located.

[0057] By way of example and not limitation, in the embodiments of this application, the network device may have mobility characteristics; for example, the network device may be a mobile device. In some embodiments of this application, the network device may be a satellite or a balloon station. For example, the satellite may be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of this application, the network device may also be a base station located on land, water, or other similar locations.

[0058] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0059] Synesthesia

[0060] Current cellular networks (including 5G networks) are used solely for communication. However, the radio electromagnetic signals used by cellular networks can be used not only for wireless data transmission and communication, but also for environmental sensing capabilities, such as user motion or gesture recognition, respiratory monitoring, measurement of terminal device movement speed, environmental imaging, and weather monitoring. Therefore, future cellular networks could be considered for use not only for communication and data transmission, but also for acquiring sensory information.

[0061] Therefore, in future communication systems, cellular networks can support sensing capabilities. As one possible implementation, a sensing control element (SF) and corresponding procedures can be added to the system architecture shown in Figure 1 to support sensing functions in 3GPP networks. Figure 2 shows another example of a communication system architecture applicable to the embodiments of this application. As shown in Figure 2, this system architecture adds an SF, which includes a control plane portion (see SF-C in Figure 2) and a user plane portion (see SF-U in Figure 2). SF-C can interact with other network elements in the control plane. For example, SF-C can interact with AMF through interface NS1, and with UDM through interface NS3, etc. SF-U can interact with other network elements in the user plane. For example, SF-U can interact with UPF through interface NS7, etc.

[0062] It should be noted that the names of SF-C and / or SF-U are not limited in this application embodiment, and they can also be other names. It should also be noted that the implementation of SF-U is not limited in this application embodiment. As one possible implementation, SF-U can be deployed as a standalone hardware device. As another possible implementation, SF-U can be centrally deployed (i.e., co-located) with other network elements; for example, SF-U can be centrally deployed with a location management function (LMF).

[0063] In some embodiments, considering the large amount of data exchanged between the terminal device and the SF, the terminal device and the SF can complete the necessary interactions for sensing services through user plane data transmission. The terminal device can establish a special PDU session and send sensing data to the SF-U via the UPF.

[0064] In some embodiments, in order to save network resources, some sensing tasks may be partially processed by sensing nodes. In this case, sensing nodes (such as terminal devices) may transmit only a small amount of data to the SF for processing through the control plane.

[0065] In some embodiments, considering the possibility that multiple terminal devices may be needed to assist in sensing, the communication system may allow terminal devices to discover and select other terminal devices as sensing nodes through the PC5 interface to complete the sensing task.

[0066] In the system architecture shown in Figure 2, the application can send a sensing request for the target terminal device to the core network. After the application sends the sensing request for the target terminal device to the core network, the core network can select the correct access network device or auxiliary terminal device through the sensing control network element or AMF, and trigger the access network device or auxiliary terminal device to perform sensing-related wireless measurement capabilities, start the measurement of sensing signals and generate sensing results.

[0067] Currently, the main wireless sensing scenarios for integrated sensing and communication include the following six types.

[0068] Scenario 1: Base station echo sensing link (single gNB sensing): The base station sends sensing signals and receives echo signals.

[0069] Scenario 2: Inter-base station sensing link (gNB-gNB sensing): Base station B receives sensing signals sent by base station A.

[0070] Scenario 3: Air Interface Uplink Sensing Link (UE-gNB Uplink Sensing): The base station receives sensing signals sent by the terminal equipment.

[0071] Scenario 4: Air Interface Downlink Sensing Link (UE-gNB Downlink Sensing): The terminal device receives sensing signals sent by the base station.

[0072] Scenario 5: Terminal device echo sensing link (single UE sensing): The terminal device sends sensing signals and receives echo signals.

[0073] Scenario 6: Perception Link between Terminal Devices (UE-UE Perception): Terminal device B receives perception signals sent by terminal device A.

[0074] The sensing task requires identifying the corresponding sensing target. When the sensing target is a terminal device, the corresponding terminal device can be found directly through its identifier (ID) or IP address information. This terminal device can then be used as the sender or receiver of the sensing signal, and other surrounding sensing nodes can be selected to complete the sensing task.

[0075] However, in scenarios such as health monitoring and exercise monitoring, the focus is on monitoring the user wearing the phone, not the phone itself. In these scenarios, if the user carries the phone, its proximity to the target can cause signal obstruction, rendering it unusable as a sensing node. However, it can be used to locate the target to be measured (i.e., the user wearing the phone). As shown in Figure 3, assuming the target to be sensed is the user in the middle, who is wearing terminal device 0 (not shown in the figure), this sensing task requires nearby base stations 1 and 2, as well as terminal device 1, to send sensing information. Terminal devices 2 and 3 need to receive the sensing signals to complete the sensing process.

[0076] AIoT

[0077] AIoT communication employs energy harvesting and backscatter communication technologies. AIoT devices refer to Internet of Things (IoT) devices that use various environmental energy sources, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy, to power themselves. These devices may have no energy storage capacity or very limited energy storage capacity (e.g., using capacitors with a capacitance of tens of microfarads (µF)). Compared to traditional IoT devices, AIoT devices offer numerous advantages, including no need for conventional batteries, no maintenance, small size, low complexity, low cost, and long lifespan.

[0078] In the embodiments of this application, the AIoT device may also be referred to as a zero-power device or an electronic tag, etc.

[0079] The system architecture of the AIoT system is described below with reference to Figures 4 and 5. As shown in Figure 4, the AIoT system 400 may include a network device 410 and an AIoT device 420. The network device 410 is used to send wireless power signals and downlink communication signals to the AIoT device 420, and to receive backscattered signals from the AIoT device. In some implementations, the network device 410 may also be called an AIoT reader. A basic AIoT device 420 includes an energy harvesting module and a backscattered communication module. In some embodiments, the AIoT device may also include a low-power computing module. In addition, the AIoT device 420 may also have a memory or sensors for storing basic information (such as item identification) or acquiring sensor data such as ambient temperature and humidity.

[0080] It should be noted that Figure 4 exemplarily illustrates a network device 410 and an AIoT device 420. Optionally, the communication system 400 may include multiple network devices, and each network device may include other numbers of AIoT devices within its coverage area; this embodiment of the application does not limit this.

[0081] In addition, in some implementations, the communication system 400 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this application embodiment.

[0082] As shown in Figure 5, the system architecture of the AIoT system can be divided into topology 1 and topology 2. In topology 1, the base station acts as an AIoT reader (i.e., the network device shown in Figure 4 is the base station). The base station, as an AIoT reader, can directly interact with the AIoT controller (also known as an AIoT network function, AIoT network element, etc.). The architecture of the base station interacting with the AIoT controller as an AIoT reader is shown in Figure 6. In topology 2, the terminal device acts as an AIoT reader (i.e., the network device shown in Figure 4 is the terminal device). As shown in Figure 7, in some embodiments, the terminal device, as an AIoT reader, can interact with the AIoT controller through the control plane (e.g., through the AMF). As shown in Figure 8, in some embodiments, the terminal device, as an AIoT reader, can interact with the AIoT controller through the user plane (e.g., through the UPF).

[0083] In some embodiments, the AIoT controller can query the AIoT reader based on area information and obtain information about all AIoT devices in that area. As one implementation, in the current AIoT management architecture, the AIoT reader can send a signal to an AIoT device to activate the device's feedback echo, which may contain information such as the AIoT device's ID. In some embodiments, after determining the AIoT device's ID, the AIoT controller can read or write data to the specified AIoT device through the AIoT reader. In other words, the current AIoT management architecture can be used to read information from and query AIoT devices.

[0084] As mentioned above, the main application scenarios of the integrated sensing architecture currently include sending sensing signals to objects that are not terminal devices and sensing them by receiving their echoes (such as health monitoring and motion monitoring). However, objects that are not terminal devices do not have communication capabilities, and the received echo signals do not carry specific object information. In sensing scenarios involving objects that are not terminal devices, the sensing node may not be able to distinguish the source of the echo signal, thus failing to accurately determine the state of the sensing target. In complex environments, it is difficult to achieve good sensing performance. Therefore, how to distinguish the source of the echo signal (i.e., how to determine whether the received echo signal is reflected back from the object to be sensed) is an urgent problem to be solved.

[0085] To address the aforementioned issues, this application proposes that an AIoT device can be attached to an object that is not a terminal device. Multiple measurements (such as phase and frequency offset) from the echo signal of the AIoT device can be used to assist in the sensing of the object. In other words, this application can use the ID information fed back by the AIoT device to identify the sensing signal of the object, while simultaneously using the echo signal of the AIoT device to estimate the sensing result. In this way, this application can effectively distinguish the source of the echo signal and expand the application scenarios of the AIoT management architecture to sensing applications.

[0086] It should be understood that the embodiments of this application are not limited to attaching AIoT devices to objects that are not terminal devices to distinguish echo signals, but rather can be any device capable of communication. For example, in addition to AIoT devices, other low-power devices, such as RedCap devices or zero-power devices, can also be attached. Furthermore, in addition to AIoT devices, terminal devices with normal power consumption, such as mobile phones, can also be attached.

[0087] In sensing scenarios, sensing nodes may need to measure the response signals (such as the echo signals mentioned above) sent by the sensing target to obtain sensing data. However, some sensing nodes (such as AIoT readers, zero-power devices, etc.) may not have the ability to measure the response signals sent by the sensing target, leading to sensing failure.

[0088] Based on this, embodiments of this application propose that a first network element can determine whether to request first sensing information or second sensing information from the first device based on the sensing and measurement capabilities of the first device (i.e., the first information hereinafter). The first sensing information is used to determine the sensing result of the sensing service, and the second sensing information is used to determine the sensing node of the sensing service. In this way, the first device can perform sensing or assist in the normal operation of sensing based on its sensing and measurement capabilities, thereby improving the sensing success rate.

[0089] The method embodiments of this application will be described below.

[0090] Figure 9 is a schematic flowchart of a wireless communication method provided in an embodiment of this application. The method shown in Figure 9 is described from the perspective of the interaction between a first device and a first network element. For ease of understanding, the first device and the first network element will be described first below.

[0091] In the embodiments of this application, the first device can act as a sensing node or a sensing auxiliary node. For example, the first device can act as a sensing node to execute a sensing process. As an example, the first device can send a sensing signal to a sensing target and receive a response signal sent by the sensing target. As another example, the first device can act as a sensing auxiliary node. As an example, the first device can assist the first network element in determining the sensing node.

[0092] It should be noted that, in the embodiments of this application, for the sensing scenario of an object that is not a terminal device, the response signal sent by the sensing target can refer to the response signal sent by the device attached to the sensing target (i.e., the object that is not a terminal device). Taking the device attached to the object that is not a terminal device as an AIoT device as an example, the response signal sent by the sensing target refers to the response signal sent by the AIoT device attached to the object that is not a terminal device. The response signal sent by the sensing target mentioned below can refer to the response signal sent by the device attached to the sensing target (such as an AIoT device), and will not be elaborated further below.

[0093] It should also be noted that, for the perception scenario of objects that are not terminal devices, the perception target can refer to the object that is not a terminal device, or it can refer to the device attached to the object that is not a terminal device (such as an AIoT device). This application embodiment does not distinguish between them.

[0094] In some embodiments, the first device can measure the response signal sent by the sensing target. For example, when the first device supports sensing measurement (or has sensing measurement capability), the first device can measure the response signal sent by the sensing target.

[0095] In some embodiments, the first device may be an AIoT reader. For example, in a scenario where a non-terminal device is sensing an object, if an AIoT device is attached to the non-terminal device object (i.e., the sensing target), then the first device in this embodiment may be an AIoT reader. However, this embodiment is not limited to this; the first device may also be other devices that can serve as sensing nodes or sensing auxiliary nodes, such as a RedCap device.

[0096] In some embodiments, the first device may be a radio frequency identification (RFID) reader.

[0097] In some embodiments, the first device may be a terminal device or a base station with low-power device (such as an AIoT device) reading function.

[0098] In the embodiments of this application, the first network element can be used to request the first device to execute a sensing process (or sensing task) or to request the first device to assist in executing a sensing process.

[0099] In some embodiments, the first network element can be a network element in the core network.

[0100] In some embodiments, the first network element can serve as a control node in the sensing process. For example, the first network element can be an SF (Signal Transfer Unit).

[0101] In some embodiments, the first network element can serve as a control node for an AIoT device. For example, the first network element can be an AIoT controller.

[0102] However, the embodiments of this application are not limited to this. For example, the first network element can be other nodes in the core network besides the SF or AIoT controller. For example, the first network element can be a node introduced in a future communication system. This node can request the first device to execute the sensing process (or sensing task) or request the first device to assist in executing the sensing process.

[0103] The method shown in Figure 9 may include step S910, which will be described below.

[0104] In step S910, the first network element sends a message to the first device. Correspondingly, the first device receives the message sent by the first network element.

[0105] In some embodiments, the message sent by the first network element to the first device may be a first message. The first message may be used to request first sensing information.

[0106] In some embodiments, the first sensing information can be used to determine the sensing result of the first sensing service. For example, the first sensing information may include sensing data, so that the first network element can process the requested sensing data to obtain the sensing result of the first sensing service. Therefore, in some embodiments, the first message used to request the first sensing information can also be understood or replaced as: the first message used to request sensing data.

[0107] The embodiments of this application do not limit the first sensing service, which can be any type of sensing service. As an example, the first sensing service can be a respiratory monitoring sensing service. As another example, the first sensing service can be a motion recognition or gesture recognition sensing service. As yet another example, the first sensing service can be an environmental imaging sensing service. As yet another example, the first sensing service can be a weather monitoring sensing service.

[0108] In some embodiments, the first sensing service may be a sensing service for objects that are not terminal devices. Alternatively, the sensing target associated with the first sensing service may be an object that is not a terminal device or a device attached to an object that is not a terminal device.

[0109] This application does not specifically limit the first sensing information, as long as it can be used to determine the sensing result of the first sensing service. Alternatively, this application does not limit the sensing data requested by the first network element. For example, the first sensing information may include one or more of the following: an identifier of the sensing target associated with the first sensing service, a measurement result of the response signal associated with the first sensing service, and a timestamp corresponding to the measurement result of the response signal associated with the first sensing service.

[0110] In some embodiments, the first sensing information may include one of the information described above. As an example, the first sensing information may include an identifier of the sensing target associated with the first sensing service. As another example, the first sensing information may include a measurement result of a response signal associated with the first sensing service. As yet another example, the first sensing information may include a timestamp corresponding to the measurement result of the response signal associated with the first sensing service.

[0111] In some embodiments, the first sensing information may include multiple types of the information described above. As an example, the first sensing information may include the identifier of a sensing target associated with the first sensing service and the measurement result of a response signal associated with the first sensing service. As another example, the first sensing information may include the identifier of a sensing target associated with the first sensing service and the timestamp corresponding to the measurement result of the response signal associated with the first sensing service. As yet another example, the first sensing information may include the measurement result of the response signal associated with the first sensing service and the timestamp corresponding to the measurement result of the response signal associated with the first sensing service. As yet another example, the first sensing information may include the identifier of a sensing target associated with the first sensing service, the measurement result of the response signal associated with the first sensing service, and the timestamp corresponding to the measurement result of the response signal associated with the first sensing service.

[0112] In some embodiments, the identifier of the sensing target associated with the first sensing service can be used to identify the sensing target associated with the first sensing service. For example, in a sensing scenario of an object that is not a terminal device, the identifier of the sensing target associated with the first sensing service can be used to identify a device (such as an AIoT device) attached to the object that is not a terminal device. That is, the identifier of the sensing target associated with the first sensing service may include the identifier of the device (such as an AIoT device) attached to the object that is not a terminal device.

[0113] In some embodiments, the identifier of the sensing target associated with the first sensing service can be used to identify the sender of the response signal associated with the first sensing service. That is, the identifier of the sensing target associated with the first sensing service can be used to indicate who sent the response signal corresponding to that identifier. In this way, the first device can distinguish the source of the response signal based on the identifier, i.e., the first device can determine whether the response signal is reflected back from the desired sensing target based on the identifier.

[0114] In some embodiments, the measurement results of the response signal associated with the first sensing service are used to determine the sensing result of the first sensing service. In some embodiments, the measurement results of the response signal associated with the first sensing service can also be understood or referred to as the sensing data of the first sensing service. This application embodiment does not limit the measurement results of the response signal associated with the first sensing service. Exemplarily, the measurement results of the response signal associated with the first sensing service may include one or more of the following: phase information, Doppler frequency shift information, received signal strength (RSS), phase amplitude information, spectral information, etc.

[0115] In some embodiments, the phase amplitude information described above may include in-phase / quadrature (I / Q) information. For example, the phase amplitude information may include the I / Q information of the response signal (i.e., the received signal) and / or the I / Q information of the channel estimation.

[0116] This application does not limit the implementation method of the first message for requesting first sensing information. As one possible implementation, the first message may include first indication information, which can be used to indicate a request for first sensing information. As another possible implementation, the message type of the first message can be used to indicate a request for first sensing information.

[0117] This application embodiment does not limit the aforementioned first indication information. In some embodiments, the first indication information may be explicit indication information. For example, the first indication information may include the type of requested sensing information. In some embodiments, the first indication information may be implicit indication information. For example, the first indication information may include the type of the first sensing service and / or the type of the first sensing information. That is, this application embodiment can implicitly request the first sensing information through the type of the first sensing service and / or the type of the first sensing information.

[0118] In some embodiments, the implicit request for first sensing information through the type of the first sensing service can also be understood as the implicit request for first sensing information through the sensing type. This application does not limit the type of the first sensing service. For example, the type of the first sensing service may include one or more of the following: respiratory monitoring, gesture recognition, action recognition, weather monitoring, environmental imaging, location sensing, etc.

[0119] In some embodiments, the implicit request for first sensing information based on the type of first sensing information can also be understood as the implicit request for first sensing information based on the sensing data type. This application does not limit the type of first sensing information. For example, the type of first sensing information may include one or more of the following: respiratory monitoring data, gesture recognition data, motion recognition data, weather monitoring data, environmental imaging data, location sensing data, etc.

[0120] As an example, the first network element may carry explicit indication information in the message sent to the first device to indicate a request for first sensing information.

[0121] As another example, the first network element can carry the type of the first sensing service in the message sent to the first device. In this way, if the first device supports the sensing measurement of the first sensing service, the first device considers the message to be used to request the first sensing information, that is, the message is the first message; if the first device does not support the sensing measurement of the first sensing service, the first device considers the message to be used to request the second sensing information, that is, the message is the second message.

[0122] As another example, the first network element can carry the type of first sensing information in the message sent to the first device. In this way, the first device can determine that the message is for requesting first sensing information, i.e., that the message is the first message, based on the type of first sensing information requested.

[0123] In some embodiments, the message sent by the first network element to the first device can be a second message. The second message can be used to request second sensing information.

[0124] In some embodiments, the second sensing information can be used to determine the sensing node of the first sensing service; that is, the second sensing information can assist the first network element in determining the sensing node of the first sensing service. In this way, the first network element can determine the sensing node based on the second sensing information, so as to send a sensing request to the determined sensing node and execute subsequent sensing procedures. Therefore, in some embodiments, the second sensing information can also be called or understood as sensing auxiliary information.

[0125] This application does not specifically limit the second sensing information, as long as it can be used to determine the sensing node of the first sensing service. Alternatively, this application does not limit the sensing auxiliary information requested by the first network element. For example, the second sensing information may include one or more of the following: the identifier of the sensing target associated with the first sensing service, the group information to which the sensing target belongs, and the category information to which the sensing target belongs.

[0126] In some embodiments, the second sensing information may include one of the information described above. As an example, the second sensing information may include the identifier of the sensing target associated with the first sensing service. As another example, the second sensing information may include group information to which the sensing target belongs. As yet another example, the second sensing information may include category information to which the sensing target belongs.

[0127] In some embodiments, the second sensing information may include multiple types of the information described above. As an example, the second sensing information may include the identifier of the sensing target associated with the first sensing service and the group information to which the sensing target belongs. As another example, the second sensing information may include the identifier of the sensing target and the category information to which the sensing target belongs. As yet another example, the second sensing information may include the group information to which the sensing target belongs and the category information to which the sensing target belongs. As yet yet another example, the second sensing information may include the identifier of the sensing target, the group information to which the sensing target belongs, and the category information to which the sensing target belongs.

[0128] For details regarding the identification of perception targets associated with the first perception service, please refer to the above text, which will not be repeated here.

[0129] The group information and / or category information to which the sensing target belongs can be used to identify (or select) a specific set of devices. For example, the group information and / or category information to which the sensing target belongs can be used to identify a specific set of AIoT devices. This application does not specifically limit the group information and / or category information to which the sensing target belongs. As an example, the group information to which the sensing target belongs may include the device group ID to which the sensing target belongs. As another example, the category information to which the sensing target belongs may include the category ID to which the sensing target belongs.

[0130] In some embodiments, the group information and / or category information to which the sensing target belongs can be treated as separate attribute information (e.g., as a separate information element (IE)). That is, the group information and / or category information can belong to a different IE than the identifier of the sensing target associated with the first sensing service. In some embodiments, the group information and / or category information to which the sensing target belongs can be included in the identifier of the sensing target associated with the first sensing service. For example, the group information and / or category information to which the sensing target belongs is a field in the identifier of the sensing target associated with the first sensing service.

[0131] This application does not limit the implementation method of the second message for requesting second sensing information. As one possible implementation, the second message may include second indication information, which can be used to indicate a request for second sensing information. As another possible implementation, the message type of the second message can be used to indicate a request for second sensing information.

[0132] This application embodiment does not limit the aforementioned second indication information. In some embodiments, the second indication information may be explicit indication information. For example, the second indication information may include the type of requested sensing information. In some embodiments, the second indication information may be implicit indication information. For example, the second indication information may include the type of the first sensing service and / or the type of the second sensing information. That is, this application embodiment can implicitly request the second sensing information through the type of the first sensing service and / or the type of the second sensing information.

[0133] In some embodiments, the implicit request for second sensing information by the type of the first sensing service can also be understood as the implicit request for second sensing information by the sensing type.

[0134] This application does not limit the type of the second sensing information in its embodiments. For example, the type of the second sensing information may include one or more of the following: the identifier of the sensing target associated with the first sensing service, the group information to which the sensing target belongs, and the category information to which the sensing target belongs. That is, this application embodiment can request the first device to report one or more of the following: the identifier of the sensing target associated with the first sensing service, the group information to which the sensing target belongs, and the category information to which the sensing target belongs. When this message is used to request one or more of the above information, it means that the message is used to implicitly request the second sensing information (i.e., the message is the second message).

[0135] As an example, the first network element may carry explicit indication information in the message sent to the first device to indicate a request for second sensing information.

[0136] As another example, the first network element can carry the type of the first sensing service in the message sent to the first device. In this way, if the first device supports the sensing measurement of the first sensing service, the first device considers the message to be used to request the first sensing information, that is, the message is the first message; if the first device does not support the sensing measurement of the first sensing service, the first device considers the message to be used to request the second sensing information, that is, the message is the second message.

[0137] As another example, the first network element can carry the type of second sensing information in the message sent to the first device. In this way, the first device can determine that the message is for requesting second sensing information, i.e., that the message is a second message, based on the type of the requested second sensing information.

[0138] In some embodiments, the first message and the second message have the same message type, or in other words, the first message and the second message are the same message, but the information carried in their fields is different. This different information is used to indicate whether the first sensing information or the second sensing information is requested.

[0139] In some embodiments, the first message and the second message have different message types, or in other words, the first message and the second message are different messages.

[0140] In this embodiment, whether the message sent by the first network element to the first device is a first message or a second message is determined based on first information. The first information can be used to indicate the sensing and measurement capabilities of the first device. That is, in this embodiment, the first network element can determine whether to request the first device to report sensing data or sensing assistance information based on the first device's sensing and measurement capabilities, thereby helping to ensure the normal operation of the first device's assisted sensing. The first information is described below.

[0141] In some embodiments, the first information used to indicate the sensing measurement capability of the first device can be understood as the first information being used to determine whether the first device supports sensing measurement, and / or which sensing measurements the first device supports.

[0142] In some embodiments, the first information may be used to indicate one or more of the following: whether the first device supports sensing measurement, whether the first device supports sensing measurement of the first sensing service, whether the first device supports discovering sensing targets associated with the first sensing service, and whether the first device supports interaction with sensing targets associated with the first sensing service.

[0143] In some embodiments, the first information may be used to indicate one of the aforementioned capabilities. As an example, the first information may be used to indicate whether the first device supports sensing measurement. As another example, the first information may be used to indicate whether the first device supports sensing measurement for a first sensing service. As yet another example, the first information may be used to indicate whether the first device supports discovering sensing targets associated with the first sensing service. As yet another example, the first information may be used to indicate whether interaction with sensing targets associated with the first sensing service is supported.

[0144] In some embodiments, the first information can be used to indicate multiple of the aforementioned capabilities. As an example, the first information can be used to indicate whether the first device supports sensing measurement and whether the first device supports sensing measurement for a first sensing service. As another example, the first information can be used to indicate whether the first device supports sensing measurement and whether the first device supports discovering sensing targets associated with the first sensing service and supports interaction with the sensing targets. As yet another example, the first information can be used to indicate whether the first device supports sensing measurement for the first sensing service and whether the first device supports discovering sensing targets associated with the first sensing service and supports interaction with the sensing targets. As yet another example, the first information can be used to indicate whether the first device supports sensing measurement, whether the first device supports sensing measurement for the first sensing service, and whether the first device supports discovering sensing targets associated with the first sensing service and supports interaction with the sensing targets.

[0145] In some embodiments, whether the first device supports sensing measurement can be understood as whether the first device supports all types of sensing measurement, or whether the first device supports sensing measurement for all sensing services. For example, "the first device supports sensing measurement" can be understood as the first device supporting all types of sensing measurement or the first device supporting sensing measurement for all sensing services. Conversely, "the first device does not support sensing measurement" can be understood as the first device not supporting any type of sensing measurement or the first device not supporting sensing measurement for any sensing service.

[0146] In some embodiments, whether the first device supports the sensing measurement of the first sensing service can be understood as whether the first device supports a certain type of sensing measurement, or in other words, whether the first device supports the sensing measurement of a certain sensing service. For example, the first device supporting the sensing measurement of the first sensing service can be understood as the first device supporting the sensing measurement of the first sensing service and supporting the sensing measurement of other sensing services, or the first device supporting the sensing measurement of the first sensing service but not supporting the sensing measurement of other sensing services. As another example, the first device not supporting the sensing measurement of the first sensing service can be understood as the first device not supporting the sensing measurement of the first sensing service and not supporting the sensing measurement of other sensing services, or the first device not supporting the sensing measurement of the first sensing service but supporting the sensing measurement of other sensing services.

[0147] In some embodiments, where the first device supports discovering sensing targets associated with the first sensing service and supports interaction with the sensing targets, the first device can interact with the sensing targets. For example, the first device can receive response signals sent by the sensing targets. As another example, the first device can receive second sensing information sent by the sensing targets.

[0148] In some embodiments, if the first device supports sensing measurement and / or the first device supports sensing measurement for the first sensing service, the message sent by the first network element to the first device can be a first message (i.e., the message in step S910 is a first message). That is, if the first information indicates that the first device supports sensing measurement and / or supports sensing measurement for the first sensing service, the message sent by the first network element to the first device can be a first message.

[0149] In some embodiments, if the first device does not support sensing measurement and / or does not support sensing measurement for the first sensing service, the message sent by the first network element to the first device can be a second message (i.e., the message in step S910 is a second message). In other words, if the first information indicates that the first device does not support sensing measurement and / or does not support sensing measurement for the first sensing service, the message sent by the first network element to the first device can be a second message.

[0150] In some embodiments, if the first device does not support sensing measurement and / or does not support sensing measurement of the first sensing service, but supports discovering sensing targets associated with the first sensing service and supports interaction with the sensing targets, then the message sent by the first network element to the first device can be a second message. That is, if the first information indicates that the first device does not support sensing measurement and / or does not support sensing measurement of the first sensing service, but supports discovering sensing targets associated with the first sensing service and supports interaction with the sensing targets, then the message sent by the first network element to the first device can be a second message.

[0151] In some embodiments, if the message sent by the first network element to the first device is a first message, after receiving the first message, the first device may perform one or more of the following operations: receive a response signal sent by a sensing target associated with the first sensing service; measure the response signal sent by the sensing target to obtain first sensing information; and send the first sensing information to the first network element. That is, in a scenario where the first device supports sensing measurement for the first sensing service, after receiving the first message, the first device can act as a sensing node to sense the sensing target, obtain sensing data, and report the sensing data to the first network element.

[0152] In some embodiments, if the message sent by the first network element to the first device is a second message, after receiving the second message, the first device may perform one or more of the following operations: request second sensing information from the sensing target associated with the first sensing service; receive the second sensing information sent by the sensing target; and send the second sensing information to the first network element. That is, in scenarios where the first device does not support sensing measurement for the first sensing service, after receiving the second message, the first device can assist the first network element in obtaining the second sensing information, so that the first network element can determine the sensing node based on the second sensing information and request the sensing node to execute subsequent sensing procedures.

[0153] In some embodiments, if the message sent by the first network element to the first device is a second message, the first network element, after receiving the second sensing information sent by the first device, can determine the sensing node that performs the first sensing service based on the second sensing information and request the sensing node to perform the first sensing service.

[0154] In some embodiments, the first device can register first information at a second network element. In this way, the first network element can subsequently obtain the first information from the second network element to determine whether to send a first message or a second message to the first device. The process of the first device registering first information is described below with reference to Figure 10.

[0155] Figure 10 is a schematic flowchart of a wireless communication method provided in another embodiment of this application. The method shown in Figure 10 is described from the perspective of the interaction between a first device, a first network element, and a second network element. For details regarding the first device and the first network element, please refer to the above text; they will not be repeated here.

[0156] The second network element has data storage and / or data query functions. In this way, after the first device registers the first information with the second network element, other network elements (such as the first network element) can query the first information. This application embodiment does not specifically limit the second network element. Exemplarily, the second network element may include one or more of the following network elements: mobility management network element, unified data management network element, network repository network element, sensing network element, and AIoT controller. Wherein, the mobility management network element can be an AMF or a network element in a future communication system with the same or similar functions as the AMF. The unified data management network element can be a UDM or a network element in a future communication system with the same or similar functions as the UDM. The network repository network element can be an NRF or a network element in a future communication system with the same or similar functions as the NRF. The sensing network element can be an SF or a network element in a future communication system with the same or similar functions as the SF. The AIoT controller can be an AIoT NF or a network element in a future communication system with the same or similar functions as the AIoT NF.

[0157] In some embodiments, the second network element may be a network element in the core network.

[0158] As an example, the second network element can be a mobility management network element.

[0159] As another example, the second network element can be a unified data management network element.

[0160] As another example, the second network element can be a network warehouse network element.

[0161] As another network element, the second network element can be a sensing network element.

[0162] As another network element, the second network element can be an AIoT controller.

[0163] In some embodiments, if the second network element is a sensing network element or an AIoT controller, the second network element may be deployed centrally with the first network element (i.e., co-located). That is, if the second network element is a sensing network element or an AIoT controller, the second network element and the first network element may be the same network element.

[0164] The method shown in Figure 10 includes steps S1010 to S1030. In step S1010, the first device sends a third message to the second network element. The third message can be used to request the registration of the first information, that is, the third message can be used to request the registration of the first device's sensing and measurement capabilities.

[0165] As an example, a first device can register that it supports sensing measurement via a third message. Alternatively, a first device can register that it does not support sensing measurement via a third message. For instance, a first device can register that it supports sensing measurement for all sensing services via a third message.

[0166] As another example, the first device can register via a third message that it supports sensing measurements for the first sensing service. Alternatively, the first device can register via a third message that it does not support sensing measurements for the first sensing service. For instance, the first device can register via a third message that it supports sensing measurements for respiratory monitoring services but does not support sensing measurements for motion recognition services.

[0167] As another example, the first device can register via a third message that it supports sensing measurement, specifying which types of sensing services it supports. Alternatively, the first device can register via a third message that it does not support sensing measurement, specifying which types of sensing services it does not support. For example, the first device can register via a third message that it supports sensing measurement, including respiratory monitoring and environmental imaging services, but not motion recognition services.

[0168] As another example, the first device can register via a third message that it does not support sensing measurement, but supports discovering sensing targets associated with the first sensing service and supports interacting with the sensing targets.

[0169] As another example, the first device can register via a third message that it does not support the sensing measurement of the first sensing service, but supports the discovery of sensing targets associated with the first sensing service and supports interaction with the sensing targets.

[0170] In step S1020, the second network element sends first information to the first network element. In this way, the first network element can determine whether to send a first message or a second message to the first device based on the first information.

[0171] This application does not limit the implementation method of the second network element sending the first information to the first network element. As one possible implementation, after receiving the first information registered (or updated) by the first device, the second network element may proactively send the first information to the first network element. As another possible implementation, the first network element may send a fourth message to the second network element. The fourth message can be used to query the first information. In this way, the first network element can determine whether to send the first message or the second message to the first device based on the query result.

[0172] In some embodiments, before the first network element sends the fourth message to the second network element, the first network element may receive the fifth message sent by the third network element. That is, in some embodiments, the first network element sending the fourth message to the second network element is triggered by the first network element receiving a request to execute the first sensing service. In other words, the first network element may send the fourth message to the second network element based on the fifth message after receiving it from the third network element.

[0173] In some embodiments, the fifth message can be used to request the execution of a first sensing service, that is, the fifth message is used to request the first network element to execute the first sensing service. Therefore, in some embodiments, the fifth message can also be called or understood as a sensing request message.

[0174] This application embodiment does not limit the information contained in the fifth message. For example, the fifth message may include one or more of the following information: the identifier of the first device, and the identifier of the sensing target associated with the first sensing service.

[0175] As an example, the fifth message may include the identifier of the first device. In this way, the first network element can query the second network element for the first information corresponding to the first device based on the identifier of the first device. Taking the first device as an AIoT reader as an example, the fifth message may include the identifier of the AIoT reader (such as the identifier of a terminal device) to indicate a request to perform the first sensing service through the AIoT reader.

[0176] As another example, the fifth message may include the identifier of the sensing target associated with the first sensing service. In this case, the first network element can determine the corresponding first device based on the identifier of the sensing target associated with the first sensing service, and query the second network element for the first information corresponding to the first device.

[0177] This application does not limit the third network element. As an example, the third network element can be an application server, for example, an AF. As another example, the third network element can be a network element in the core network, for example, an SMF or a network element in a future communication system with the same or similar functions as an SMF.

[0178] This application does not limit the method by which the second network element stores and / or queries the first information. As one possible implementation, the second network element may store the identifier of the first device and the corresponding first information. As another possible implementation, the second network element may store the identifier of the first device, the type of sensing service, and the first information corresponding to that sensing service type. When the second network element stores the identifier of the first device and the first information corresponding to that identifier, the first network element can subsequently query the first information corresponding to that identifier based on the identifier of the first device.

[0179] In step S1030, the first network element sends a message to the first device based on the first information. Alternatively, the first network element determines whether to send a first message or a second message to the first device based on the first information.

[0180] For details regarding step S1030, please refer to the above description of step S910; it will not be repeated here.

[0181] For ease of understanding, the following description uses an AIoT reader as the first device and an AIoT device as the sensing target as an example to illustrate the process of the method of this application. It should be noted that the embodiments described below are for illustrative purposes only, and in actual execution, fewer or more steps may be included than those in the embodiments. This application does not limit the scope of the embodiments.

[0182] Example 1: The first device supports sensing measurement or sensing measurement for the first sensing service.

[0183] In Example 1, the AIoT reader can register first information with the second network element. Afterwards, upon receiving a sensing request, the first network element can first query the first information from the second network element. When the AIoT reader supports sensing measurement for the first sensing service, the first network element can directly request the first sensing information (i.e., sensing data) from the AIoT reader, and the AIoT reader will then report the first sensing information. This process will be described below with reference to Figure 11.

[0184] Figure 11 is a flowchart illustrating a wireless communication method according to another embodiment of this application. The method shown in Figure 11 may include steps S1101 to S1108.

[0185] In step S1101, the AIoT reader sends a third message to the second network element to register the first information.

[0186] For example, the AIoT reader registers first information with the second network element, indicating that the AIoT reader supports sensing measurement and / or supports sensing measurement for the first sensing service.

[0187] In step S1102, the second network element sends a response message of the third message to the AIoT reader. That is, the second network element can send a registration response to the AIoT reader, such as registration success or registration failure.

[0188] In step S1103, the third network element sends a fifth message (i.e., a sensing request) to the first network element to request the first network element to execute the sensing process.

[0189] In some embodiments, the fifth message may carry the identifier of the AIoT reader (such as a terminal device).

[0190] In step S1104, the first network element sends a fourth message to the second network element to query the first information (i.e., sensing and measurement capabilities) of the AIoT reader. It should be noted that Embodiment 1 is not limited to this; for example, the second network element may actively send the first information of the AIoT reader to the first network element.

[0191] In this embodiment, the first network element learns that the AIoT reader supports sensing measurement and / or supports sensing measurement for the first sensing service.

[0192] In step S1105, the first network element sends a first message to the AIoT reader to request the first sensing information.

[0193] In some embodiments, the first message may carry first indication information (explicit or implicit) to indicate that the first message is used to request first sensing information. Alternatively, the message type of the first message may indicate that the first message is used to request first sensing information.

[0194] In step S1106, the AIoT reader interacts with the AIoT device and performs estimation processing on the received response signal to obtain first sensing information.

[0195] For example, an AIoT reader can obtain the measurement results of the response signals sent by an AIoT device, the timestamp corresponding to the measurement results, and the identifier of the AIoT device.

[0196] As one implementation, the AIoT reader can measure and estimate the response signal sent by the AIoT to obtain the measurement result of the response signal.

[0197] In step S1107, the AIoT reader sends the first sensing information to the first network element.

[0198] In step S1108, the first network element and other network elements continue to execute the subsequent sensing process.

[0199] For example, the first network element can process the received first sensing information to obtain the sensing result, and then send the sensing result to the third network element.

[0200] For example, the first network element can send the received first sensing information to other network elements so that the other network elements can process the first sensing information to obtain the sensing result.

[0201] Example 2: The first device does not support sensing measurement or does not support sensing measurement for the first sensing service.

[0202] In Example 2, after the third network element initiates a sensing request through an AIoT reader that does not support AIoT sensing, the first network element can ensure that AIoT-assisted sensing proceeds normally through an additional capability negotiation process.

[0203] In Example 2, the AIoT reader can register first information with the second network element. Afterwards, upon receiving a sensing request, the first network element can first query the first information from the second network element. When the AIoT reader does not support the sensing measurement of the first sensing service, the first network element can request second sensing information (such as sensing auxiliary information) from the AIoT reader, and the AIoT reader will report the second sensing information. Afterwards, the first network element can use the second sensing information to search for an AIoT reader that supports the sensing measurement of the first sensing service and obtain the first sensing information from the new AIoT reader. This process will be described below with reference to Figure 12.

[0204] Figure 12 is a schematic flowchart of a wireless communication method according to another embodiment of this application. The method shown in Figure 12 may include steps S1201 to S1208.

[0205] In step S1201, the AIoT reader sends a third message to the second network element to register the first information.

[0206] For example, the AIoT reader registers first information with the second network element, indicating that the AIoT reader does not support sensing measurement and / or does not support sensing measurement of the first sensing service.

[0207] In step S1202, the second network element sends a response message of the third message to the AIoT reader. That is, the second network element can send a registration response to the AIoT reader, such as registration success or registration failure.

[0208] In step S1203, the third network element sends a fifth message to the first network element to request the first network element to execute the sensing process.

[0209] In some embodiments, the fifth message may carry the identifier of the AIoT reader (such as a terminal device).

[0210] In step S1204, the first network element sends a fourth message to the second network element to query the first information (i.e., sensing and measurement capabilities) of the AIoT reader. It should be noted that Embodiment 2 is not limited to this; for example, the second network element may actively send the first information of the AIoT reader to the first network element.

[0211] In this embodiment, the first network element learns that the AIoT reader does not support sensing measurement and / or does not support sensing measurement for the first sensing service.

[0212] In step S1205, the first network element sends a second message to the AIoT reader to request second sensing information.

[0213] In some embodiments, the second message may carry second indication information (explicit or implicit) to indicate that the second message is used to request second sensing information. Alternatively, the message type of the second message may indicate that the second message is used to request second sensing information.

[0214] In step S1206, the AIoT reader interacts with the AIoT device and obtains the second sensing information.

[0215] For example, an AIoT reader can obtain group information and / or category information of AIoT devices to select a specific set of AIoT devices. Another example is that an AIoT reader can also obtain other information such as the identifier of the AIoT devices.

[0216] As one implementation method, an AIoT reader can discover and select AIoT devices, thereby obtaining information such as group information, category information, and identifier of the AIoT device from that device.

[0217] In step S1207, the AIoT reader sends the second sensing information to the first network element.

[0218] In step S1208, the first network element and other network elements continue to execute the subsequent sensing process.

[0219] For example, the first network element can re-find the AIoT reader that supports the first sensing service based on the second sensing information, and obtain the first sensing information from the new AIoT reader.

[0220] Subsequently, the first network element can process the first sensing information to obtain a sensing result and send the sensing result to the third network element. Alternatively, the first network element can send the first sensing information to other network elements so that the other network elements can process the first sensing information to obtain a sensing result.

[0221] It should be noted that the above description uses the method of this application applied to a perception scenario. However, the embodiments of this application are not limited to this. For example, the method of this application can also be applied to a positioning scenario. That is, in a positioning scenario, the first network element can also query the positioning measurement capabilities of the first device (e.g., whether it supports positioning measurement, whether it supports positioning measurement for certain services, whether it supports interaction with the positioning target, etc.). Other content is similar to that in the perception scenario, and for the sake of brevity, this application will not repeat it.
