[0061] It should be understood that the terms "system" and "network" are often used interchangeably in this document.

[0064] 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.

[0065] Figure 2 is a schematic diagram of the 5G 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 (Access and Mobility Management Function) is the mobility management function in the core network, and the SMF (Session Management Function) 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 (Policy Control Function) is the policy management function in the core network, responsible for formulating policies related to UE mobility management, session management, and charging. The UPF (User Plane Function) 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.

[0066] 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.

[0067] 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. In one possible scenario, the application sends a sensing request for the 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. In the initial stage of B5G communication and sensing integration, the specific architecture can be referenced in Figure 3.

[0068] 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.

[0069] The current Ambient Internet of Things (AIoT) management architecture can manage low-power AIoT devices. It can send signals to AIoT devices via an AIoT reader to activate the device's feedback echo, which may contain the AIoT device's ID information. However, currently, this system is only used for reading information from and querying AIoT devices; it is not used for sensing.

[0070] Therefore, how to acquire sensing data using passive IoT devices is a technical problem that needs to be solved.

[0071] This application proposes a method for acquiring sensing data using passive IoT devices. A core network element (which may be an AIoT management network element or a sensing network element) sends a sensing request to an AIoT reading device (which may be a UE or RAN). The AIoT reading device sends a sensing signal to the AIoT device and collects the signals fed back by the AIoT device. The collected AIoT device feedback signals are sent to the core network element in the form of sensing data (which may specifically include phase, Doppler frequency shift, received signal strength (RSS), I / Q data (phase amplitude information, which may be the received signal or channel estimation I / Q information), spectral information, etc., and may also include timestamps, AIoT device IDs, etc.) for AIoT-assisted sensing.

[0072] 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:

[0073] S410, The reading device sends a first signal to the first terminal;

[0074] S420. The reading device receives a response signal sent by the first terminal, the response signal carrying the identification (ID) information of the first terminal;

[0075] S430. The reading device performs estimation processing on the response signal to obtain measurement information.

[0076] 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.

[0077] The first terminal may include at least one of AIoT devices, passive IoT devices, low-power devices, and RFID devices.

[0078] The reading device receives a response signal containing the first terminal's ID information from a first terminal. It can then determine that the received response signal is reflected from a sensed object, and perform estimation processing on the response signal to obtain measurement information, i.e., sensed data. In some examples, the AIoT device is attached to the surface of the sensed object; therefore, the response signal from the AIoT device can be used by the reading device to sense the object. Multiple AIoT devices can be attached to or bound to the sensed object. The reading device can send a first signal to one or more AIoT devices attached to / bound to the sensed object and receive response signals from those devices, thereby sensing the object.

[0079] 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.

[0080] In some examples, the measurement information includes at least one of phase, Doppler shift, RSS, phase amplitude information, and spectral information.

[0081] 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.

[0082] In some implementations, before step S410, the method may further include: the reading device receiving a first message sent by a first network element, the first message being used to request sensing data.

[0083] The first network element may include at least one of the following: a sensing network element / sensing control network element (SF), a network element for processing sensing data, and a network element for managing AIoT devices (such as an AIoT controller).

[0084] Accordingly, after step S430, the process may further include: the reading device sending a second message to the first network element, the second message carrying the measurement information.

[0085] Through the above process, the reading device can send measurement information to the first network element according to the request of the first network element, so that the first network element can obtain the sensing data of the terminal device.

[0086] The first message received by 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.

[0087] In some examples, the first message may also carry at least one of the following: ID information, group information, type information, and location information of one or more first terminals; this information is used to instruct the first network element to request which first terminals' perception information to obtain.

[0088] Accordingly, the reading device can select a first terminal based on the above information, and in step S410, send first information to the selected first terminal. The method by which the reading device selects the first terminal may include selecting the first terminal based on at least one of the group information, type information, and location information of the one or more first terminals.

[0089] In the above example, the reading device selects a first terminal before sending the first signal and sends a first signal to the selected first terminal. In other examples, after receiving response signals from multiple first terminals, the reading device may select these first terminals based on at least one of the ID information, group information, type information, and location information of one or more first terminals carried in the first message, and perform estimation processing on the response signal of the selected first terminal to obtain measurement information. In this case, the response signal sent by the first terminal also carries at least one of the group information, type information, and location information of the first terminal; the reading device performs estimation processing on the response signal, including: the reading device determines whether to select a first terminal based on at least one of the group information, type information, and location information of the first terminal; if selected, the reading device performs estimation processing on the response signal.

[0090] The second message sent by the reading device to the first network element may also carry at least one of the ID information, group information, type information, and location information of the first terminal.

[0091] In other examples, the first request received by the reading device does not carry any indication for the first terminal, i.e., it does not carry the first terminal's ID information, group information, type information, or location information. In this case, the reading device can select the first terminal based on its capabilities (such as whether it supports the corresponding sensing service), selecting only the first terminals that meet the conditions, and sending a first signal to the first terminals that meet the conditions.

[0092] 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:

[0093] S510, The first terminal receives the first signal sent by the reading device;

[0094] S520, the first terminal sends a response signal to the reading device, the response signal carrying the ID information of the first terminal.

[0095] The first terminal may include at least one of AIoT devices, passive IoT devices, low-power devices, and RFID devices.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] In some implementations, the response signal also carries at least one of the group information, type information, and location information of the first terminal.

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.

[0107] In some examples, the first message may also carry at least one of the following: ID information, group information, type information, and location information of one or more first terminals. This information may instruct the reading device to acquire the sensing and / or measurement information of which first terminals. The first terminals may include at least one of AIoT devices, passive IoT devices, low-power devices, and RFID devices.

[0108] In some implementations, the measurement information includes at least one of phase, Doppler shift, RSS, phase amplitude information, and spectral information.

[0111] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0112] Example 1:

[0113] In this embodiment, a first network element (which may be a sensing network element (SF), a network element for processing sensing data, or a network element for managing AIoT devices, such as an AIoT Network Function (AIoT NF) or an AIoT controller) sends a first message to the AIoT reader, carrying one or more specific AIoT device IDs (e.g., AIoT tag IDs) and explicit or implicit sensing indication information. The AIoT reader sends AIoT signals (which may be dedicated sensing signals or reused AIoT device control signals) to the AIoT devices and receives signal responses from the AIoT devices, performing measurement estimation on the signals. The AIoT reader then sends a second message to the first network element, carrying AIoT sensing / positioning measurement information and the corresponding AIoT device ID.

[0114] As shown in Figure 7, the specific implementation process of this embodiment includes the following steps:

[0115] S701, the first network element (which may be a sensing network element, i.e., SF, or an AIoT device control network element, such as an AIoT NF or AIoT controller) sends a first message to the AIoT reading device, which carries one or more specific AIoT device IDs (e.g., AIoT tag IDs) and explicit or implicit sensing indication information. Specifically, it may be explicit sensing indication information, used to indicate that this request is for AIoT sensing data; it may also be implicit indication information, such as carrying the sensing service type or sensing data type, or the message itself may be a special request message, representing a request for AIoT sensing data.

[0116] AIoT reading devices can be dedicated AIoT reading devices (such as RFID readers), or UE terminal devices or RAN base station devices with low-power tag reading capabilities.

[0117] S702, The AIoT reading device sends an AIoT signal to the AIoT device. This AIoT signal may be a dedicated sensing signal or a reused AIoT device control signal.

[0118] S703, the AIoT reading device receives signal responses from AIoT devices, wherein the response signal of each AIoT device carries the device's ID information.

[0119] The S704 AIoT reading device performs estimation processing on the received response signal to obtain various measurement information of the signal sent by the corresponding AIoT device, such as phase, Doppler frequency shift, RSS, I / Q data (phase amplitude information, which may be the I / Q information of the received signal or channel estimation), spectrum information, etc. It may also include the timestamp corresponding to the measurement information, AIoT device ID, etc.

[0120] The S705 and AIoT reading devices send a second message to the first network element, which includes sensing / positioning measurement information and the corresponding AIoT device ID information, and may also include the corresponding timestamp information. Specifically, the measurement information may include phase, Doppler frequency shift, RSS, I / Q data (phase amplitude information, which may be the received signal or channel estimation I / Q information), spectral information, etc.

[0121] S706, Subsequent positioning and sensing process. Specifically, the measurement information may be processed by the first network element, or it may be further sent to other network elements for processing to obtain the sensing results.

[0122] Example 2:

The request may use group information, type information, or location information, or a combination of multiple restrictive information may be used.

[0124] Specifically, the first network element (which may be a sensing network element, i.e., SF, or an AIoT device control network element, such as an AIoT NF or AIoT controller) sends a first message to the AIoT reading device. This message carries group / type information of the AIoT devices (this information can be used to select a specific group of AIoT devices; specifically, it can use, for example, an AIoT group / type ID, which can be a separate attribute or included in the AIoT device's ID information as a field; there are no restrictions here). It may also carry specified location information, requesting only measurement information from AIoT devices at the corresponding location. The first message may also carry explicit or implicit sensing indication information. The AIoT reading device sends AIoT signals to the AIoT devices (which may be dedicated sensing signals or reused AIoT device control signals) and receives the signal responses from the AIoT devices, performing measurement estimation on the signals. The AIoT reading device then sends a second message to the first network element, carrying AIoT sensing / positioning measurement information and the corresponding AIoT device ID.

[0125] As shown in Figure 8, the specific implementation process of this embodiment includes the following steps:

[0126] S801, the first network element (which may be a sensing network element, i.e., SF, or an AIoT device control network element, such as an AIoT NF or AIoT controller) sends a first message to the AIoT reading device, carrying the group / type information of the AIoT devices and explicit or implicit sensing indication information. The group / type information of the AIoT devices can be used to select a specific group of AIoT devices. Specifically, it can use, for example, an AIoT group / type ID (this information can be a separate attribute or included in the ID information of the AIoT devices as a field; no restriction is placed here). The explicit or implicit sensing indication information may be explicit, indicating that this request is for AIoT sensing data; it may also be implicit, such as carrying the sensing service type or sensing data type, or the message itself may be a special request message representing a request for AIoT sensing data.

[0127] AIoT reading devices can be dedicated AIoT reading devices (such as RFID readers), or UE terminal devices or RAN base station devices with low-power tag reading capabilities.

[0128] In step S802, the AIoT reader may first select AIoT devices, for example, based on group information, device type information, or location information, and only select AIoT devices that meet the criteria for subsequent interaction. This step may involve first interacting with connectable AIoT devices to obtain their corresponding device information before selection, with subsequent steps only interacting with the selected AIoT devices; alternatively, this step may not involve interaction, and specific information may be added in step S803 to determine whether to interact only with the selected AIoT devices.

[0129] S803, the AIoT reader sends an AIoT signal to the AIoT device. This AIoT signal may be a dedicated sensing signal or a reused AIoT device control signal.

[0130] S804: The AIoT reader receives signal responses from AIoT devices, where each AIoT device's response signal carries its ID information. It may also carry corresponding AIoT device group information and AIoT device type information.

[0131] S805, the AIoT reading device performs estimation processing on the received response signal to obtain various measurement information of the signal sent by the corresponding AIoT device, such as phase, Doppler shift, RSS, I / Q data (phase amplitude information, which may be the I / Q information of the received signal or channel estimation), spectral information, etc., and may also include the timestamp corresponding to the measurement information, AIoT device ID, etc. Furthermore, if the AIoT device was not selected in step S802, it may be selected in this step based on the AIoT device's group / type information and location information.

[0132] S806: The AIoT reading device sends a second message to the first network element, which includes sensing / positioning measurement information and the corresponding AIoT device ID information, and may also include the corresponding timestamp information. Specifically, the measurement information may include phase, Doppler shift, RSS, I / Q data (phase amplitude information, which may be the received signal or channel-estimated I / Q information), spectral information, etc. It may also include the group / type information of the corresponding AIoT device, and may also include the location information of the AIoT device.

[0133] S807, Subsequent positioning and sensing process. Specifically, the measurement information may be processed by the first network element, or it may be further sent to other network elements for processing to obtain the sensing results.

[0134] Example 3:

[0135] In this embodiment, the request sent by the first network element to the AIoT reading device only carries sensing indication information.

[0136] Specifically, the first network element (which may be a sensing network element, i.e., SF, or an AIoT device control network element, such as an AIoT NF or AIoT controller) sends a first message to the AIoT reading device, carrying explicit or implicit sensing indication information. The AIoT reading device sends an AIoT signal to the AIoT device (which may be a dedicated sensing signal or a reused AIoT device control signal) and receives the signal response from the AIoT device, performing measurement estimation on the signal. The AIoT reading device then sends a second message to the first network element, carrying AIoT sensing / positioning measurement information and the corresponding AIoT device ID.

[0137] As shown in Figure 9, the specific implementation process of this embodiment includes the following steps:

[0138] S901, the first network element (which may be a sensing network element, i.e., SF, or an AIoT device control network element, such as an AIoT NF or AIoT controller) sends a first message to the AIoT reading device, carrying explicit or implicit sensing indication information. This explicit indication information may indicate that the request is for AIoT sensing data; it may also be implicit, for example, carrying the sensing service type or sensing data type, or the message itself may be a special request message representing a request for AIoT sensing data. The AIoT reading device can be a dedicated AIoT reading device (such as an RFID reader), a UE terminal device with low-power tag reading capabilities, or a RAN base station device.

[0139] S902. Optionally, the AIoT reader may first select AIoT devices, for example, based on the capabilities of the AIoT devices (whether they support the corresponding sensing services), and only select AIoT devices that meet the conditions for subsequent interaction. This step may involve first interacting with connectable AIoT devices to obtain their corresponding device information before selection, with subsequent steps only interacting with the selected AIoT devices; alternatively, this step may not involve interaction, and specific information may be added in step S903 to determine whether to interact only with the selected AIoT devices.

[0140] S903, the AIoT reader sends an AIoT signal to the AIoT device. This AIoT signal may be a dedicated sensing signal or a reused AIoT device control signal.

[0141] S904, the AIoT reading device receives signal responses from AIoT devices, wherein the response signal of each AIoT device carries the device's ID information.

[0142] The S905 and AIoT reading devices perform estimation processing on the received response signals to obtain various measurement information of the signals sent by the corresponding AIoT devices, such as phase, Doppler frequency shift, RSS, I / Q data (phase amplitude information, which may be the I / Q information of the received signal or channel estimation), spectrum information, etc. It may also include the timestamp corresponding to the measurement information, AIoT device ID, and other information.

[0143] The S906 AIoT reading device sends a second message to the first network element, which includes sensing / positioning measurement information and the corresponding AIoT device ID information, and may also include the corresponding timestamp information.
