The network devices and terminal devices can be specific devices in this application embodiment, which will not be described in detail here. The communication device may also include other devices in the communication system, such as network controllers, mobility management entities, and other network entities.

[0074] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0075] Figure 2 is a schematic diagram of the 5G network architecture. The UE connects to the Access Network (AN) via the Uu interface to establish an access layer connection, exchanging access layer messages and radio data. The UE connects to the Access and Mobility Management Function (AMF) via the N1 interface to establish a non-access layer (NAS) connection, exchanging NAS messages. The AMF is the mobility management function in the core network, and the SMF is the session management function in the core network. In addition to managing the UE's mobility, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The PCF is the policy control function in the core network, responsible for formulating policies related to UE mobility management, session management, and charging. The UPF is the user plane function in the core network, transmitting data with the external data network via the N6 interface and with the AN via the N3 interface.

[0076] 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 action or gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, and weather monitoring. Therefore, future cellular networks could be considered not only for communication and data transmission, but also for acquiring sensory information.

[0077] Currently, there is discussion about supporting sensing capabilities in post-5G (B5G, Beyond 5G) networks. This is achieved by adding a Sensing Function (AMF) and corresponding procedures to support sensing functions in 3GPP networks. When an application sends a sensing request for a target UE to the 3GPP core network, the core network selects the correct access network device or auxiliary UE through the Sensing Function or AMF, triggering the ability to perform sensing-related radio measurements, initiating the measurement of sensing information, and generating sensing results.

[0078] The main wireless sensing scenarios for integrated sensing are as follows:

[0079] 1) Base station echo sensing link (single gNB sensing): The base station sends sensing signals and receives echo signals;

[0080] 2) Inter-base station sensing link (gNB-gNB sensing): Base station B receives sensing signals sent by base station A;

[0081] 3) Air interface uplink sensing link (UE-gNB uplink sensing): The base station receives sensing signals sent by the terminal;

[0082] 4) Air interface downlink sensing link (UE-gNB downlink sensing): The terminal receives sensing signals sent by the base station;

[0083] 5) Terminal echo sensing link (single UE sensing): The terminal sends sensing signals and receives echo signals;

[0084] 6) Inter-terminal sensing link (UE-UE sensing): Terminal B receives sensing signals sent by Terminal A.

[0085] The perception task requires identifying the corresponding perception target. When the perception target is a UE, the corresponding UE can be found directly through the UE's ID or UE IP address information, and the UE can be used as the sender or receiver of the perception signal. Then, other surrounding perception nodes can be selected to complete the perception task.

[0086] In one possible scenario, the application sends a sensing request for the target UE to the core network of the 3GPP network. The core network selects the correct access network device or auxiliary UE through the sensing control network element or AMF, and triggers the ability to perform sensing-related radio measurements, initiating the measurement of sensing information and generating sensing results. In the initial stage of B5G communication sensing integration, the specific architecture can be referenced in Figure 3.

[0087] Currently, considering the large amount of data exchanged between the UE and the sensing network element, the UE can complete the necessary interaction for sensing services through user plane data transmission. The UE can establish a special PDU session to send sensing data to the SF-U (the user plane part of the sensing network element, which may also have other names, or may be shared with the LMF; this is not limited here, the above diagram is only an example architecture) via the UPF. Simultaneously, for some sensing tasks, to conserve network resources, the sensing node may be allowed to perform partial processing, transmitting only a small amount of data to the SF for processing via the control plane. Furthermore, considering the possibility of multiple UEs assisting in sensing, the UE is allowed to discover and select other UEs as sensing nodes through the PC5 interface to complete the sensing task.

[0088] A primary scenario for the current integrated sensing architecture is sending sensing signals to non-UE objects and sensing them by receiving their echoes. However, because non-UE objects lack communication capabilities and the received echo signals do not carry specific object information, it is impossible to distinguish whether the received echo signals are reflected back from the object to be sensed.

[0089] The current Ambient Internet of Things (AIoT) management architecture can manage low-power AIoT devices. The AIoT controller queries a specific AIoT reader based on area information to obtain information on all AIoT devices in that area. It can also read or write data to a designated AIoT device through its corresponding AIoT reader using a specific AIoT device ID. However, it currently does not support locating or sensing AIoT devices through the AIoT reader.

[0090] Combining the two existing technologies mentioned above, AIoT devices can be attached to non-UE objects. Multiple measurements (such as phase and frequency offset) from the echo signals of the AIoT devices can be used to assist in the perception of these non-UE objects. Specifically, the ID information fed back by the AIoT devices is used to identify the non-UE objects and the sensing signals, while the echo signals from the AIoT devices are used to estimate the perception results. This effectively addresses the technical challenges in non-UE object perception scenarios.

[0091] Based on this, this application proposes a method for sensing using passive IoT devices. The sensing network element directly or through an AIoT control network element obtains signal measurement information from an AIoT reader for AIoT-assisted sensing. Specifically, the method also includes the sensing network element obtaining AIoT device-related information from the AIoT control network element or the AIoT reader / UE, and obtaining measurement information from a sensing-capable AIoT reader for AIoT-assisted sensing.

[0092] Figure 4 is a schematic flowchart of a sensing method 400 according to an embodiment of this application. This method can optionally be applied to any of the systems shown in Figures 1 to 3, but is not limited thereto. The method includes at least a portion of the following:

[0093] S410, The reading device receives a first message sent by the first network element, the first message being used to request sensing data;

[0094] S420. The reading device sends a second message to the first network element, the second message carrying measurement information.

[0095] The reading device may include at least one of a device with low-power tag reading capability and a radio frequency identification (RFID) reading device. For example, the device with low-power tag reading capability may be a UE terminal device or a radio access network (RAN) base station device with low-power tag reading capability. In one example, the reading device includes an AIoT reader.

[0096] Through the above process, the reading device receives a first message from the first network element requesting sensing data, and sends a second message carrying measurement information (which can be sensing / positioning measurement information) to the first network element, thereby enabling the reading device to locate or sense terminal devices (such as AIoT devices).

[0097] The first network element may include at least one of the following: a sensing function (SF), a network element for processing sensing data, and a network element for managing AIoT devices (such as an AIoT controller).

[0098] In some examples, the reading device can obtain the measurement information by sending a signal to the first terminal, receiving a response signal from the first terminal, and performing estimation processing on the response signal.

[0099] In some examples, the reading device estimates the response signal by measuring its phase, Doppler shift, channel estimation results, and / or spectral information, and may perform further processing. For instance, the reading device first acquires phase amplitude (I / Q) information (which may be channel estimation results or I / Q information of the received signal), and then performs further processing based on this I / Q information, using algorithms to acquire phase, Doppler shift, and / or spectral information. Furthermore, it may further process and acquire other information, such as integrating information from multiple terminal devices to generate point cloud information.

[0100] In some implementations, step S410 is followed by:

[0101] The reading device sends a first signal to the first terminal;

[0102] The reading device receives a response signal sent by the first terminal, the response signal carrying the ID information of the first terminal;

[0103] The reading device performs estimation processing on the response signal to obtain the measurement information.

[0104] Since the response signal received by the reading device carries the ID information of the first terminal, the reading device can distinguish whether the response signal is reflected back from the object to be sensed, thereby realizing the sensing of the first terminal.

[0105] The first terminal may include at least one of AIoT devices, passive IoT devices, low-power devices, and RFID devices.

[0106] In some implementations, the measurement information includes at least one of phase, Doppler shift, received signal strength (RSS), phase amplitude information, and spectral information.

[0107] In some implementations, the first signal sent by the reading device to the first terminal may include a sensing signal or a control signal. For example, the first signal may be a dedicated sensing signal or a reused AIoT device control signal.

[0108] In some implementations, the second message also carries at least one of the first terminal's ID information, group information, type information, and location information.

[0109] In some implementations, the reading device may also acquire sensing-related information based on instructions from the second network element and send the acquired sensing-related information to the second network element. For example, this may include the following steps:

[0110] The device receives sensing indication information sent by the second network element;

[0111] Read the device to obtain sensing-related information;

[0112] The reading device sends the sensing-related information to the second network element.

[0113] The perception-related information may include at least one of the following: ID information, group information, type information, and location information of one or more first terminals.

[0114] The second network element may include a sensing network element (such as SF) or a network element used to process sensing data.

[0115] In some implementations, the reading device may acquire sensing-related information in the following ways:

[0116] The reading device interacts with the first terminal to obtain the sensing-related information; or...

[0117] Read the device query local context to obtain relevant information about this perception.

[0118] In the above manner, the reading device can obtain perception-related information by interacting with the first terminal or querying information stored locally, and then provide the obtained perception-related information to the second network element for selection of the reading device.

[0119] Figure 5 is a schematic flowchart of a sensing method 500 according to an embodiment of this application. This method can optionally be applied to any of the systems shown in Figures 1 to 3, but is not limited thereto. The method includes at least a portion of the following:

[0120] S510, The first terminal receives the first signal sent by the reading device;

[0121] S520, the first terminal sends a response signal to the reading device, the response signal carrying the identification (ID) information of the first terminal.

[0122] The reading device may include at least one of a device with low-power tag reading capability and an RFID reading device. For example, the device with low-power tag reading capability may be a UE terminal device or a RAN base station device with low-power tag reading capability. In one example, the reading device includes an AIoT reader.

[0123] The first terminal may include at least one of AIoT devices, passive IoT devices, low-power devices, and RFID devices.

[0124] The first terminal sends a response signal containing its ID information back to the reading device. This enables the reading device to determine that the received response signal is reflected from the sensed object. The device then performs estimation processing on the response signal to obtain measurement information, i.e., sensed data. This response signal can be used by the reading device for estimation processing to obtain measurement information.

[0125] In some implementations, the first signal received by the first terminal may include a sensing signal or a control signal. For example, the first signal may be a dedicated sensing signal or a reused AIoT device control signal.

[0126] For a specific example of the first terminal execution method 500 in this embodiment, please refer to the relevant description of the first terminal in the above method 500. For the sake of brevity, it will not be repeated here.

[0127] Figure 6 is a schematic flowchart of a sensing method 600 according to an embodiment of this application. This method can optionally be applied to any of the systems shown in Figures 1 to 3, but is not limited thereto. The method includes at least a portion of the following:

[0128] S610, The first network element sends a first message to the reading device, which is used to request sensing data;

[0129] S620, the first network element receives a second message sent by the reading device, the second message carrying measurement information.

[0130] Through the above process, the first network element sends a first message to the reading device to request sensing data, and receives a second message carrying measurement information (which can be sensing / positioning measurement information) from the reading device, thus enabling the reading device to locate or sense terminal devices (such as AIoT devices).

[0131] The first network element may include at least one of the following: a sensing network element (such as SF), a network element for processing sensing data, and a network element for managing AIoT devices (such as an AIoT controller).

[0132] The reading device may include at least one of a device with low-power tag reading capability and an RFID reading device. For example, the device with low-power tag reading capability may be a UE terminal device or a RAN base station device with low-power tag reading capability.

[0133] The first message sent by the first network element to the reading device may carry at least one of sensing indication information, sensing service type, and sensing data type. The sensing indication information may be explicit or implicit. For example, the sensing indication information may be explicit, indicating that the first message is a message requesting AIoT sensing data. Alternatively, the sensing indication information may be implicit, such as carrying a sensing service type or sensing data type, or the message itself may be a specific request message representing a request for AIoT sensing data.

[0134] In some implementations, the measurement information includes at least one of phase, Doppler shift, RSS, phase amplitude information, and spectral information.

[0135] In some implementations, the second message may also carry at least one of the first terminal's ID information, group information, type information, and location information, thereby indicating the first terminal corresponding to the measurement information carried in the second message.

[0136] The first terminal may include at least one of AIoT devices, passive IoT devices, low-power devices, and RFID devices.

[0137] In some implementations, before step S610, the following steps are also included:

[0138] The first network element receives a sensing request sent by the second network element. The sensing request carries at least one of the following: ID information, group information, type information, location information of one or more first terminals, and ID information of the reading device.

[0139] In some implementations, after step S620, the following may also be included:

[0140] The first network element processes the measurement information to obtain the sensing result;

[0141] The first network element sends a sensing response to the second network element, and the sensing response carries the sensing result.

[0142] Through the above process, the first network element can perform the positioning and sensing process based on the request of the second network element, and feed back the obtained sensing results to the second network element.

[0143] In some implementations, before step S610, the following may also be included:

[0144] The first network element sends a read device query request to the third network element. The read device query request carries the ID information, group information, type information, and location information of one or more first terminals.

[0145] The first network element receives the reading device query response sent by the third network element, and the reading device query response carries the information of the reading device.
