[0001] This application relates to the field of communications, and more particularly to a communication method and apparatus. Background Technology

[0002] Wireless sensing technology analyzes changes in wireless signals during propagation to obtain the characteristics of the signal propagation space, thereby enabling scene perception. The perceived target (also called the sensing target or measurement target) can be a vehicle, tree, animal, etc., which are only illustrative examples and not specific limitations.

[0003] Wireless sensing typically encompasses both traditional and intelligent wireless sensing technologies. The process of intelligent wireless sensing generally includes the following parts: data collection, training an artificial intelligence (AI) / machine learning (ML) model based on the collected data, and analysis and reasoning based on the collected data and the results of the model training. It is evident that wireless sensing technology relies heavily on collected data, which plays a crucial role in various scenarios. How to effectively collect data in intelligent wireless sensing technology remains an unresolved issue. Summary of the Invention

[0004] This application provides a communication method and apparatus for data collection in intelligent wireless sensing technology.

[0005] Firstly, this application provides a communication method applied to a first data collector, or a component (such as a processor, chip, chip system, circuit, or other component) or software module within the first data collector. Taking the application of this method to a first data collector as an example, the method may include: the first data collector acquiring a first sensing parameter and a second sensing parameter; the first sensing parameter indicating measurement information between a sensing node and a measurement target; the second sensing parameter indicating attribute information of the measurement target; in model processing within an intelligent wireless sensing scenario, the first data collector uses the first sensing parameter as input information for the model and the second sensing parameter as ground-truth label information for the model.

[0006] Using this method, the first data collector can obtain the first perception parameter and the second perception parameter, and use the obtained first perception parameter and the second perception parameter for the model processing process in the intelligent wireless sensing scenario (such as AI / ML training and inference process). In other words, the aforementioned communication method can realize data acquisition in intelligent wireless sensing technology and provide reliable input data for model processing, thereby supporting data collection and model processing in intelligent wireless sensing scenarios.

[0007] In one possible design, the method by which the first data collector obtains the second sensing parameter may include: the first data collector sending first configuration information to the measurement target, the first configuration information being used to instruct the measurement target to configure the attribute information of the measurement target according to the first configuration information; the first data collector receiving first confirmation information from the measurement target, the first confirmation information being used to indicate that the measurement target has configured the attribute information of the measurement target according to the first configuration information; and the first data collector using the first configuration information as the second sensing parameter.

[0008] With this design, the first data collector can configure the attribute information of the measurement target through the first configuration information. Therefore, this attribute information can also be directly used as the second sensing parameter, thereby improving the efficiency of the first data collector in obtaining the second sensing parameter.

[0009] In one possible design, the method by which the first data collector acquires the second sensing parameter may include: the first data collector receiving the second sensing parameter from the measurement target.

[0010] With this design, the target object can actively report attribute information (i.e., the second sensing parameter) to the first data collector, and the first data collector can then obtain the second sensing parameter, thereby simplifying the complexity of the first data collector in obtaining the second sensing parameter.

[0011] In one possible design, the method by which the first data collector obtains the second sensing parameter may include: the first data collector determining the second sensing parameter based on the first sensing parameter.

[0012] With this design, the first data collector can estimate (indirectly) the second sensing parameter based on the first sensing parameter, thereby enabling the first data collector to achieve linkage in acquiring the first and second sensing parameters and improve the efficiency of acquiring the second sensing parameter.

[0013] In one possible design, the method by which the first data collector obtains the second perception parameter may include: the first data collector receiving a first message from a network-side node, the first message including a ground-truth label field, the ground-truth label field being used to indicate the second perception parameter.

[0014] With this design, the first data collector can obtain the second perception parameter through the network side node, and the second perception parameter is indicated by the ground-truth label field of the first message, which can simplify the complexity of the first data collector obtaining the second perception parameter.

[0015] In one possible design, the first message further includes a first auxiliary information field, which is used to indicate first auxiliary information related to the second sensing parameter.

[0016] By adopting this design, the first data collector can also obtain first auxiliary information related to the second sensing parameters. Thus, the first data collector can also use the first auxiliary information as model input in the model processing process under the intelligent wireless sensing scenario, which can further improve the accuracy and precision of model processing.

[0017] For example, the first auxiliary information may include at least one of first quality information, first timestamp, or first related information; the first quality information is used to evaluate the quality of the second sensing parameter, the first timestamp is used to indicate the time when the second sensing parameter was generated, and the first related information is used to indicate configuration information related to the second sensing parameter.

[0018] In one possible design, the method by which the first data collector obtains the first sensing parameter may include: the first data collector receiving a second message sent by the sensing node, the second message including a measurement field field used to indicate the first sensing parameter; the first sensing parameter being determined by the sensing node based on a first echo signal, the first echo signal being fed back by the measurement target based on a first sensing reference signal sent by the sensing node.

[0019] With this design, the first data collector can obtain the first sensing parameters through the sensing node, and the first sensing parameters are indicated by the measurement field field of the second message. Therefore, the first data collector can use the first sensing parameters indicated by the measurement field field to support model processing in intelligent wireless sensing scenarios, simplifying the complexity of obtaining the first sensing parameters.

[0020] In one possible design, the second message further includes a second auxiliary information field, which is used to indicate second auxiliary information related to the first perception parameter.

[0021] By adopting this design, the first data collector can also obtain second auxiliary information related to the first sensing parameters. Thus, the first data collector can also use the second auxiliary information as model input in the model processing process under the intelligent wireless sensing scenario, which can further improve the accuracy and precision of model processing.

[0022] For example, the second auxiliary information may include at least one of second quality information, a second timestamp, and second related information; the second quality information is used to evaluate the quality of the first sensing parameter, the second timestamp is used to indicate the time when the first sensing parameter was generated, and the second related information is used to indicate configuration information related to the first sensing parameter.

[0023] In one possible design, the method by which the first data collector acquires the first sensing parameter may include: the first data collector sending a second sensing reference signal; the first data collector receiving a second echo signal; the second echo signal being fed back by the measurement target based on the second sensing reference signal; and the first data collector determining the first sensing parameter based on the second echo signal.

[0024] Using this design, the first data collector can determine the first sensing reference signal by sending a sensing reference signal and receiving the echo, thereby simplifying the complexity of the first data collector in obtaining the first sensing parameters. In the aforementioned design, the first data collector can also be a sensing node.

[0025] In one possible design, the first data collector may also receive a first request from the second data collector; the first data collector may also send a first response message to the second data collector in response to the first request, the first response message including at least one of the following: the first sensing parameter and the second sensing parameter;

[0026] Alternatively, the method by which the first data collector obtains the first sensing parameter and the second sensing parameter includes: the first data collector sending a second request to the second data collector; the first data collector receiving a second response message from the second data collector in response to the second request, the second response message including at least one of the following: the first sensing parameter and the second sensing parameter.

[0027] With this design, the first data collector and the second data collector can transmit the sensing data they have acquired (including the first sensing parameters and the second sensing parameters) to each other. In this way, even if one data collector has not collected enough sensing data, it can obtain the required or missing sensing data from other data collectors.

[0028] In one possible design, the first response message and the second response message may each include a ground-truth label field and / or a measurement field, wherein the measurement field is used to indicate the first sensing parameter and the ground-truth label field is used to indicate the second sensing parameter.

[0029] With this design, the first sensing parameter and the second sensing parameter can be indicated by the measurement field and the ground-truth label field, respectively. Thus, the first data collector can use the first sensing parameter indicated by the measurement field as the input information of the model, and use the second sensing parameter indicated by the ground-truth label field as the ground-truth label information of the model, thereby improving the efficiency and accuracy of model processing in intelligent wireless sensing scenarios.

[0030] In one possible design, the first response message and the second response message may further include a first auxiliary information field and / or a second auxiliary information field, respectively. The first auxiliary information field is used to indicate first auxiliary information related to the second sensing parameter, and the second auxiliary information field is used to indicate second auxiliary information related to the first sensing parameter.

[0031] With this design, the first auxiliary information and the second auxiliary information are indicated by the first auxiliary information field and the second auxiliary information field, respectively. Thus, the first data collector can also use the first auxiliary information and the second auxiliary information to support model processing in intelligent wireless sensing scenarios, thereby improving the accuracy of model processing.

[0067] To make the objectives, technical solutions, and beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0068] In the description of this application, unless otherwise stated, " / " signifies "or," for example, A / B can mean A or B. "And / or" in this application merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, in the description of this application, "at least one" refers to one or more items, and "multiple" refers to two or more items. In the description of this application, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0069] The technical solutions provided in this application can be applied to 5G systems, or to future communication systems (such as 6G) or other similar communication systems. Furthermore, the technical solutions provided in this application can be applied to cellular links, public land mobile networks (PLMNs), machine-to-machine (M2M) networks, Internet of Things (IoT) networks, or other networks. They can also be applied to links between devices, such as device-to-device (D2D) links. D2D links can also be called sidelinks, which are also referred to as secondary links or auxiliary links. In this application, the above terms all refer to links established between devices of the same type, and their meanings are the same. The so-called "same type of devices" can be links between terminal devices, links between base stations, links between relay nodes, etc., and this application does not limit this.

[0070] To better illustrate the solution of this application, the technical terms involved in this application are explained below:

[0071] 1. A sensing node, also known as an induction node, signal detection node, or sensing device, is not specifically limited here. A sensing node can be a terminal device or a network device, without further limitation. Sensing nodes assist operating nodes in locating the sensed target.

[0072] 2. The measurement target is the device to be sensed. The measurement target can be an active device (e.g., an active reflector) or a passive device. An active reflector can receive signals and transmit signals according to a predetermined method (predefined scattering coefficients, shapes, and time delays between transmitted and received signals, etc.). Active reflectors have controllable characteristics such as scattering coefficients, shapes, and time delays between transmitted and received signals. Passive devices cannot transmit or receive signals, but can reflect, diffract, or scatter signals.

[0073] 3. A range image is a one-dimensional distribution image of the target's scattering points within a specific viewing angle. In this embodiment, the range image can be the result obtained by the sensing node after pulse compression of the echo signal. For example, the sensing node sends a sensing reference signal, and the area where the sensing target is located (or the sensing range) is divided into multiple range cells along the line of sight. The echo signal within each range cell is used to determine the range image corresponding to that range cell; for example, the sum of the echo signals within each range cell is the range image corresponding to that range cell.

[0074] Figure 1 This is a schematic diagram of an architecture for a communication system applicable to embodiments of this application. For example... Figure 1 As shown, the communication system may include at least one network device (or network-side node), such as network device 110. Figure 1 As shown, the communication system may also include at least one terminal device (referred to as a sensing node in some examples) (the example in the figure is vehicle 120, which may also be referred to as terminal device 120 below). In this communication system, both the network device and the terminal device can act as data collectors, collecting and storing the data required for model training in intelligent wireless sensing technology. In this application, the terms "data" and "sensing data" may be used interchangeably. Figure 1 As shown, the communication system also includes at least one measurement target 130, which may be an active device (e.g., an active reflector) or a passive device.

[0075] like Figure 1 As shown, when the measurement target 130 is an active reflector, the network device 110 can send signals to the measurement target 130 (indicated by solid arrows in the figure) to configure some or all attribute information (such as the scattering coefficient and shape of the active reflector) for the active reflector. Optionally, the measurement target 130 can also actively report some or all attribute information to the network device 110 (not shown in the figure). Optionally, the measurement target 130 can send signals to the vehicle 120 in a predetermined manner (indicated by dashed arrows in the figure).

[0076] In some examples, the communication system may also include radar, wireless routers, smart speakers, electronic door locks, and IoT devices (not shown in the figure), all of which can act as data collectors to acquire sensing data.

[0077] Terminal equipment can be a device capable of receiving network device scheduling and instruction information, providing voice and / or data connectivity to users, or a handheld device with wireless connectivity, or other processing devices connected to a wireless modem, or a station (STA) device. Terminal equipment can communicate with one or more core networks or the Internet via a radio access network (RAN). For example, terminal equipment can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices. Terminal equipment can also be referred to as a subscriber unit (SS), subscriber station (MS), mobile station (MS), remote station (AP), access point (AP), remote terminal, access terminal, user agent, customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc. Terminal equipment can also be wearable devices. Terminal equipment can also be equipment in next-generation communication systems. For example, terminal devices in 5G networks or terminal devices in future PLMN networks, and terminal devices in next-generation radio (NR) communication systems.Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, desktop computers, customer-premises equipment (CPE), mobile internet devices (MID), wearable devices (such as smartwatches, smart bracelets, pedometers, etc.), in-vehicle equipment (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electricity meters, etc.), intelligent robots, workshop equipment, 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, or wireless terminals in smart homes, and flying equipment (such as intelligent robots, hot air balloons, drones, airplanes), etc. Terminal devices can also be other devices with terminal functions. For example, a terminal device can also be a device that performs terminal functions in D2D communication.

[0078] Network equipment is an entity on the network side used to transmit or receive signals. Examples include transmission reception points (TRPs) and gNBs. Network equipment can be an access point (AP) in a wireless local area network (WLAN), a global system for mobile communication (GSM), or a base station (BS). A base station can be a base transceiver station (BTS) in code division multiple access (CDMA), a node B (NB) in wideband code division multiple access (WCDMA), or an evolved node B (eNB or eNodeB) in long term evolution (LTE). Network equipment can also be a relay station or access point, or in-vehicle equipment, wearable devices, and network equipment in 5G networks, or in future evolved PLMNs, or gNodeB / gNB devices in NR systems. In some deployments, a gNB may include a centralized unit (CU) and a distributed unit (DU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU is responsible for handling non-real-time protocols and services. This includes implementing radio resource control (RRC), service data adaptation protocol (SDAP) functions, and packet data convergence protocol (PDCP) layer functions. The DU is responsible for handling physical layer protocols and real-time services. This includes implementing radio link control (RLC), medium access control (MAC), and physical (PHY) layer functions. The gNB may also include an active antenna unit (AAU). The AAU implements some physical layer processing functions, radio frequency processing, and active antenna-related functions. Since information from the RRC layer ultimately becomes information from the PHY layer, or is derived from information from the PHY layer...Therefore, under this architecture, higher-layer signaling (e.g., RRC layer signaling) can also be considered to be sent by the DU, or by the DU and AAU. It is understood that the network device can be one or more of the following: CU node, DU node, and AAU node. Furthermore, the CU can be a network device in the radio access network (RAN), or a network device in the core network (CN); this application does not limit this. Additionally, in the embodiments of this application, the network device provides services to a cell, and 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. For example, a small cell can include: a metro cell, a micro cell, a pico cell, a femto cell, etc. Because small cells have small coverage areas and low transmission power, they can provide high-speed data transmission services. Furthermore, in other possible cases, the network device can be any other device that provides wireless communication functionality to the terminal device. The embodiments of this application do not limit the specific technology or device form used in the network device. For example, in an open radio access network (ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through a software module, a hardware module, or a combination of software and hardware modules.

[0079] like Figure 2 As shown, in intelligent wireless sensing technology, the AI ​​framework includes: a data collection module, a model training module, a model inference module, a model management module, and a model storage module. The sensing data collected by the data collection module can include training data, monitoring data, and inference data; the data collection module can be one of the aforementioned modules. Figure 1 The system comprises two modules: a data collection module and a model training module. The model training module trains an AI / ML model using the sensory data collected by the data collection module in a data-driven manner (by learning the input / output relationship) and then uses the trained AI / ML model for subsequent inference. The module inference module uses the trained AI / ML model to generate a set of outputs based on a set of inputs. The model management module monitors the inference performance of the AI / ML model. The module storage module is responsible for storing the trained or updated model. Data can be transferred between the modules, thus realizing the entire process of intelligent wireless sensing technology.

[0080] To achieve data collection in intelligent wireless sensing technology, embodiments of this application provide a communication method. This communication method can be implemented as described above. Figure 1 Implemented in the communication system shown, Figure 1 The sensing data collected by the data collector can be used for Figure 2 The intelligent wireless sensing technology shown.

[0081] The communication method provided in the embodiments of this application will now be described in conjunction with the accompanying drawings. Figure 3 A communication method provided in this application embodiment may include the following steps:

[0083] Optionally, the first sensing parameter, used to indicate the measurement information between the sensing node and the measurement target, may include, but is not limited to, the sampling results of the echo signal and / or range image of the measurement target.

For example, the first auxiliary information related to the second sensing parameter may include, but is not limited to, at least one of the following: first quality information describing the quality of the second sensing parameter, a first timestamp indicating the generation of the second sensing parameter, and first related information about the second sensing parameter. Specifically, the first quality information can be used to evaluate the quality of the second sensing parameter, the first timestamp can be used to indicate the time when the second sensing parameter was generated, and the first related information can be used to indicate various configuration information related to the second sensing parameter. In some examples, this configuration information may be the location of the transceiver antenna, the number of transceiver antennas, the imaging area, bandwidth, frequency band, etc.

[0085] In one possible design, the first data collector may also acquire second auxiliary information related to the first sensing parameter. For example, the second auxiliary information related to the first sensing parameter may include, but is not limited to, at least one of the following: second quality information describing the quality of the first sensing parameter, a second timestamp indicating the generation of the first sensing parameter, and second related information concerning the first sensing parameter. Specifically, the second quality information can be used to evaluate the quality of the first sensing parameter, the second timestamp can be used to indicate the time when the first sensing parameter was generated, and the second related information can be used to indicate various configuration information related to the first sensing parameter.

[0086] In some examples, the first data collector may only acquire the first perceived parameters. For example, in Figure 2 During the perception data collection process corresponding to the model inference module shown, the collection and calculation of the second perception parameter are not involved, so it is not necessary to obtain the second perception parameter.

[0087] It should be understood that in model processing within intelligent wireless sensing scenarios, the sensing data may include the aforementioned first sensing parameters and / or second sensing parameters, and may also include at least one of first auxiliary information and second auxiliary information. In some examples, Figure 4 This application provides a data structure for perceptual data, namely a perceptual data mapping format for AI / ML training and inference processes. Figure 4 The left-middle column lists the machine learning parameters required by the AI / ML model: {model input; ground-truth label and other information}.

Figure 4 The right-middle column shows the actual perceived data corresponding to each machine learning parameter. Specifically, as follows... Figure 4 As shown, the measurement results can correspond to the first perception parameter (i.e., model input) mentioned above; the ground-truth label information can correspond to the second perception parameter mentioned above; the quality information can correspond to the first quality information and the second quality information mentioned above; the timestamp can correspond to the first timestamp and the second timestamp mentioned above; and the related information can correspond to the first related information and the second related information mentioned above.

[0088] The following describes a method provided by embodiments of this application for the first data collector to acquire the second sensing parameter in S301 under four different circumstances.

[0089] Scenario 1 (Network-side configuration): Assuming the measurement target is an active reflector and the first data collector is a network-side node, the method by which the first data collector obtains the second sensing parameter may include the following steps:

[0090] Step A1: The first data collection direction sends first configuration information to the measurement target. The first configuration information is used to instruct the measurement target to configure the attribute information of the measurement target according to the first configuration information.

[0091] Step A2: The first data collector receives a first confirmation message from the measurement target, which indicates that the measurement target has configured its attribute information according to the first configuration information.

[0092] Step A3: The first data collector uses the first configuration information as the second sensing parameter.

[0093] In some examples, assuming the first data collector is a network-side node, and the first data collector is different from the sensing node (e.g., UE or BS), and the measurement target is an active reflector, the aforementioned steps A1 to A3 can be... Figure 5a The implementation is shown in S5a-1 and S5a-2, which will be introduced later. Figure 5a Please provide a detailed description.

[0094] Scenario 2 (Active Reporting from Measurement Target): Assuming the measurement target is an active reflector and the first data collector is a network-side node, the method by which the first data collector obtains the second sensing parameter may include the following steps:

[0095] Step B1: The measurement target sends the second sensing parameters to the first data collector; correspondingly, the first data collector receives the second sensing parameters from the measurement target.

[0096] In some examples, assuming the first data collector is a network-side node, and the first data collector is different from the sensing node (e.g., UE or BS), and the measurement target is an active reflector, the aforementioned step B1 can be performed by... Figure 5a The implementations shown in S5a-3 and S5a-4 will be discussed later. Figure 5a Please provide a detailed description.

[0097] Scenario 3: Assuming the first data collector is a network-side node or terminal device, the method by which the first data collector obtains the second sensing parameter may include the following steps:

[0098] Step C1: The first data collector determines the second sensing parameters based on the first sensing parameters. For example, the first data collector can obtain the imaging result by performing algorithms such as compressed sensing and back projection on the first sensing parameters. This imaging result is the second sensing parameter estimated by the first data collector based on the first sensing parameters.

[0099] Optionally, based on the aforementioned scenario one, two, or three, the first data collector can determine the first auxiliary information according to the second sensing parameters. For example, the first data collector can calculate / analyze the aforementioned first auxiliary information according to the second sensing parameters and a preset algorithm.

[0100] In some examples, assuming the first data collector is a network-side node, and the network-side node is different from the sensing node (e.g., UE or BS), the aforementioned step C1 can be achieved through... Figure 5c The S5c-4 shown is used for implementation, which will be introduced later. Figure 5c Please provide a detailed description.

[0101] Scenario 4: Assume the first data collector is the sensing node (e.g.) Figure 1 The method by which the first data collector obtains the second sensing parameter (as shown in the terminal device) may include the following steps:

[0102] Step D1: The network-side node determines the second sensing parameter; the second sensing parameter is used to indicate the attribute information of the measurement target.

[0103] Step D2: The network-side node sends a first message to the first data collector; correspondingly, the first data collector receives the first message from the network-side node. The first message includes a ground-truth label field, which indicates a second sensing parameter, enabling the first data collector to use the first sensing parameter as the model's ground-truth label information during model processing in an intelligent wireless sensing scenario.

[0104] In the embodiments of this application, the method of indicating the second perception parameter through the ground-truth label field can refer to conventional methods, and this application does not limit it. For example, the second perception parameter can be directly stored in the current ground-truth label field; or, the second perception parameter can be stored in other field fields, and the current ground-truth label field field can indicate the field field used to store the second perception parameter.

[0105] Optionally, before executing step D2, the first data collector may send a fourth request to the network-side node; correspondingly, the network-side node may also receive the fourth request from the first data collector. The fourth request is used to request the acquisition of the first message.

[0106] In some examples, it is assumed that the first data collector is the sensing node (e.g., UE or BS), which is different from the network-side node, and the measurement target is an active reflector. The aforementioned steps D1 and D2 can be... Figure 5bThis is achieved using S5b-1 to S5b-6 as shown, which will be introduced later. Figure 5b Please provide a detailed description.

[0107] In one possible design of the above-described scenario four, the network-side node in step D1 can determine the second sensing parameter through the following methods a and b.

[0108] Method a (network-side configuration) includes:

[0109] Step E1: The network-side node sends second configuration information to the measurement target. The second configuration information is used to instruct the measurement target to configure its attribute information according to the second configuration information.

[0110] Step E2: The network-side node receives a second confirmation message from the measurement target, which indicates that the measurement target has configured its attribute information according to the second configuration information.

[0111] In some examples, the aforementioned method a can be achieved through Figure 5b The implementation is shown in S5b-1 and S5b-2, which will be introduced later. Figure 5b Please provide a detailed description.

[0112] Method b (active reporting by the measurement target) includes:

[0113] Step F1: The target being measured sends the second sensing parameters to the network-side node; correspondingly, the network-side node receives the second sensing parameters from the target being measured.

[0114] In some examples, the aforementioned method b can be achieved through Figure 5b The implementation is shown in S5b-3 and S5b-4, which will be introduced later. Figure 5b Please provide a detailed description.

[0115] Optionally, based on the aforementioned situation four, the first message may further include a first auxiliary information field, which is used to indicate first auxiliary information related to the second sensing parameter. In the embodiments of this application, the method of indicating the first auxiliary information through the first auxiliary information field can refer to conventional methods, and this application does not limit it.

[0116] The following describes two methods for the first data collector to acquire the first sensing parameter in S301 provided in the embodiments of this application.

[0117] Method 1: The first data collector can obtain the first sensing parameters through the sensing node. This includes the following steps:

[0118] Step G1: The sensing node sends the first sensing reference signal.

[0119] Step G2: The sensing node receives the first echo signal; the first echo signal is the feedback from the measurement target based on the first sensing reference signal.

[0120] In the embodiments of this application, the first echo signal is fed back by the measurement target based on the first sensing reference signal. It can also be understood that the first echo information is the signal after the sensing reference signal sent by the sensing node is transmitted, reflected or scattered by the measurement target.

[0121] Step G3: The sensing node sends a second message to the first data collector; correspondingly, the first data collector receives the second message sent by the sensing node. The second message includes a measurement field, which indicates the first sensing parameters, enabling the first data collector to use these parameters as input information for the model in the intelligent wireless sensing scenario. The first sensing parameters are determined by the sensing node based on the first echo signal, which is fed back from the measurement target based on the first sensing reference signal sent by the sensing node.

[0122] In the embodiments of this application, the method of indicating the first sensing parameter through the measurement field can refer to conventional methods, and this application does not limit it. For example, the first sensing parameter can be directly stored in the current measurement field; or the first sensing parameter can be stored in other field fields, and the current measurement field field can indicate the field field used to store the first sensing parameter.

[0123] Optionally, before executing step G3, the first data collector may send a third request to the sensing node; correspondingly, the sensing node may also receive a third request from the first data collector. The third request is used to request the acquisition of the second message.

[0124] In some examples, assuming the first data collector is a network-side node, and the first data collector is different from the sensing node (e.g., UE or BS), the aforementioned steps G1 to G3 can be... Figure 5a This can be achieved through steps S5a-7 to S5a-9 as shown; or, the aforementioned steps G1 to G3 can be achieved through... Figure 5c The implementations shown are S5c-1 to S5c-3, which will be introduced later. Figure 5a and Figure 5c Detailed description

[0125] Based on the aforementioned method one, the second message may further include a second auxiliary information field, which is used to indicate second auxiliary information related to the first sensing parameter. In the embodiments of this application, the method of indicating the second auxiliary information through the second auxiliary information field can refer to conventional methods, and this application does not limit it.

[0126] Method 2: The first data collector directly acts as a sensing node to acquire the first sensing parameters. This includes the following steps:

[0127] Step H1: The first data collector sends a second sensing reference signal.

[0128] Step H2: The first data collector receives the second echo signal; the second echo signal is fed back from the measurement target based on the second sensing reference signal.

[0129] Step H3: The first data collector determines the first sensing parameters based on the second echo signal.

[0130] In some examples, it is assumed that the first data collector is the sensing node (e.g., UE or BS), which is different from the network-side node, and the measurement target is an active reflector. Steps H1 to H3 can then be performed... Figure 5b This is achieved using S5b-7 to S5b-9 as shown, which will be introduced later. Figure 5b Please provide a detailed description.

[0131] Based on the aforementioned method two, the first data collector can determine the second auxiliary information based on the first sensing parameters. For example, the first data collector can calculate / analyze the aforementioned second auxiliary information based on the first sensing parameters and a preset algorithm.

[0132] Continue to refer to Figure 3 S302: In the model processing of the intelligent wireless sensing scenario, the first data collector uses the first sensing parameter as the input information of the model and the second sensing parameter as the ground-truth label information of the model.

[0133] In some examples, combined Figure 2 and Figure 4 The first data collector can Figure 4 The first sensing parameter corresponding to the measurement result is used as Figure 2 The input information of the model, and Figure 4 The second perceptual parameter corresponding to the ground-truth label information is used as Figure 2 The ground-truth label information of the model. Optionally, the first data collector can also use the first auxiliary information and the second auxiliary information in model processing in intelligent wireless sensing scenarios. For example, the first data collector can use the first quality information in the first auxiliary information and the second quality information in the second auxiliary information as the input value corresponding to the quality indicator of the model; or, the first data collector can use the first timestamp in the first auxiliary information and the second timestamp in the second auxiliary information as the input value corresponding to the timestamp of the model.

[0134] In one possible design, different data collectors can also transmit or share their acquired sensing data with each other (e.g., via a side link). This allows for the acquisition of supplementary sensing data when a collector's sensing data is insufficient, thereby improving the comprehensiveness of data collection in intelligent wireless sensing technology.

[0135] For example, the first data collector can provide perceived data to other data collectors (such as the second data collector), specifically including the following steps:

[0136] Step I1: The first data collector can also receive a first request from the second data collector.

[0137] Step I2: The first data collector may also send a first response message to the second data collector in response to the aforementioned first request. The first response message includes at least one of the following: the first sensing parameter and the second sensing parameter.

[0138] In the aforementioned example, the first data collector is the provider of the perceived data (e.g., Figure 6a As shown in UE 2), the second data collector is the requester of the perceived data (e.g., Figure 6a As shown in UE 1), the aforementioned steps I1 to I2 can be achieved through... Figure 6a This is achieved using S6a-1 to S6a-3 as shown. Assuming the first data collector is a sensing node (e.g., a UE) and the second data collector is a network-side node, the aforementioned steps I1 to I2 can be implemented through... Figure 6b This is achieved through S6b-1 to S6b-3 as shown, and will be discussed later. Figure 6a and Figure 6b Please provide a detailed description.

[0139] For example, the first data collector can also obtain the first and second sensing parameters through other data collectors (such as the second data collector), specifically including the following steps:

[0140] Step J1: The first data collector sends a second request to the second data collector.

[0141] Step J2: The first data collector receives a second response message from the second data collector in response to the aforementioned second request. The second response message includes at least one of the following: the first perception parameter and the second perception parameter.

[0142] In the aforementioned example, the first data collector is the party requesting the perceived data (e.g., Figure 6a As shown in UE 1), the second data collector is the provider of the sensed data (e.g., Figure 6aAs shown in UE 2); the aforementioned steps J1 to J2 can be achieved through Figure 6a This is achieved through S6a-1 to S6a-3 as shown, and will be discussed later. Figure 6a Please provide a detailed description.

[0143] It should be understood that the aforementioned second data collector can be a sensing node or a network-side node, and this application does not limit it.

[0144] Optionally, the first response message and the second response message each include a ground-truth label field and / or a measurement field, wherein the measurement field indicates the first sensing parameter, and the ground-truth label field indicates the second sensing parameter. The indication method of the ground-truth label field and / or measurement field in the first response message can be as described in the preceding first message and / or second message. The first response message and the second response message may also each include a first auxiliary information field and / or a second auxiliary information field, wherein the first auxiliary information field indicates first auxiliary information related to the second sensing parameter, and the second auxiliary information field indicates second auxiliary information related to the first sensing parameter.

[0145] Based on the communication methods shown in S301 and S302 above, when the first data collector and the measurement target are different, this application can use different communication methods to realize data collection in intelligent wireless sensing technology. Some application scenarios are illustrated below.

[0146] Figure 5a This is a communication example diagram provided for an embodiment of this application. Figure 5a This method is applicable to scenarios where the first data collector is a network-side node, the first data collector is different from the sensing node (e.g., UE or BS), and the measurement target is an active reflector. The specific steps include:

[0147] S5a-1: The network-side node sends the configuration information corresponding to the second sensing parameter (i.e., the first configuration information in step A1 above) to the active reflector.

[0148] S5a-2: The active reflector sends an acknowledgment character (ACK) 1 to the network-side node. ACK 1 is used to indicate that the active reflector has completed configuration.

[0149] S5a-3: The active reflector sends the second sensing parameter to the network-side node.

[0150] S5a-4: The network-side node sends ACK 2 to the active reflector. ACK 2 is used to indicate that the network-side node has received the second sensing parameter.

[0151] It should be understood that, Figure 5a In the communication method shown, only S5a-1 and S5a-2, or only S5a-3 and S5a-4, need to be executed; it is not necessary to execute all of them.

[0152] S5a-5: The network-side node calculates the first auxiliary information corresponding to the second sensing parameter; the first auxiliary information may include at least one of the following: the quality indicator corresponding to the second sensing parameter, the timestamp corresponding to the second sensing parameter, and the relevant information corresponding to the second sensing parameter.

[0153] S5a-6: The network-side node sends help information (such as a preset algorithm for the second auxiliary information) to the sensing node. This help information can be used to calculate the second auxiliary information (such as the quality indication corresponding to the first sensing parameter).

[0154] It should be understood that, Figure 5a In the communication method shown, S5a-5 and S5a-6 are both optional actions.

[0155] S5a-7: The sensing node sends a sensing reference signal.

[0156] S5a-8: The sensing node receives the echo signal and calculates the first sensing parameter. Optionally, the sensing node may also calculate the second auxiliary information corresponding to the first sensing parameter; the second auxiliary information includes at least one of the following: the quality indicator corresponding to the first sensing parameter, the timestamp corresponding to the first sensing parameter, and the relevant information corresponding to the first sensing parameter.

[0157] S5a-9: The sensing node sends the first sensing parameters to the network-side node. Optionally, the sensing node may also send the aforementioned second auxiliary information to the network-side node.

[0158] In some examples, in addition to sending the first sensing parameters to the network-side node, the sensing node can also send the first indication information to the network-side node. The first indication information is used to indicate that the first sensing parameters can be used as input information for the model in the model processing under the intelligent wireless sensing scenario.

[0159] S5a-10: Network-side nodes store sensing data. The sensing parameters include a first sensing parameter and / or a second sensing parameter, and may also include at least one of the following: a quality indicator corresponding to the first sensing parameter, a timestamp corresponding to the first sensing parameter, relevant information corresponding to the first sensing parameter, a quality indicator corresponding to the second sensing parameter, a timestamp corresponding to the second sensing parameter, and relevant information corresponding to the second sensing parameter.

[0160] Figure 5b This is another communication example diagram provided for an embodiment of this application. Figure 5b This applies to scenarios where the primary data collector is the sensing node (e.g., UE or BS), the sensing node differs from the network-side node, and the measurement target is an active reflector. Specifically, it includes the following steps:

[0161] S5b-1: The network-side node sends the configuration information corresponding to the second sensing parameter (i.e., the first configuration information in step A1 above) to the active reflector.

[0162] S5b-2: The active reflector sends ACK 3 to the network-side node. ACK 3 is used to indicate that the active reflector has been configured.

[0163] S5b-3: The active reflector sends the second sensing parameter to the network-side node.

[0164] S5b-4: The network-side node sends ACK 4 to the active reflector. ACK 4 is used to indicate that the network-side node has received the second sensing parameter.

[0165] It should be understood that, Figure 5b In the communication method shown, only S5b-1 and S5b-2, or only S5b-3 and S5b-4, need to be executed; it is not necessary to execute all of them.

[0166] S5b-5: The network-side node calculates the first auxiliary information corresponding to the second sensing parameter; the first auxiliary information may include at least one of the following: the quality indicator corresponding to the second sensing parameter, the timestamp corresponding to the second sensing parameter, and the relevant information corresponding to the second sensing parameter.

[0167] S5b-6: The network-side node sends the second sensing parameters to the sensing node. Optionally, the network-side node may also send the aforementioned first auxiliary information to the network node.

[0168] In some examples, in addition to sending the second sensing parameters to the sensing node, the network-side node can also send a second indication message to the sensing node. The second indication message is used to indicate that the second sensing parameters can be used as the ground-truth label information of the model in the model processing under the intelligent wireless sensing scenario.

[0169] S5b-7: Network-side nodes send help information (such as a preset algorithm for second auxiliary information) to sensing nodes. This help information can be used for the calculation of second auxiliary information (such as the quality indication corresponding to the first sensing parameter).

[0170] It should be understood that, Figure 5b In the communication method shown, S5b-5 and S5b-7 are both optional actions.

[0171] S5b-8: The sensing node sends a sensing reference signal.

[0172] S5b-9: The sensing node receives the echo signal and calculates the first sensing parameter. Optionally, the sensing node can also calculate the second auxiliary information corresponding to the first sensing parameter; the second auxiliary information includes at least one of the following: the quality indicator corresponding to the first sensing parameter, the timestamp corresponding to the first sensing parameter, and the relevant information corresponding to the first sensing parameter.

[0173] S5b-10: The sensing node stores sensing data. The sensing parameters include a first sensing parameter and / or a second sensing parameter, and may also include at least one of the following: a quality indicator corresponding to the first sensing parameter, a timestamp corresponding to the first sensing parameter, relevant information corresponding to the first sensing parameter, a quality indicator corresponding to the second sensing parameter, a timestamp corresponding to the second sensing parameter, and relevant information corresponding to the second sensing parameter.

[0174] Figure 5c This is another communication example diagram provided for an embodiment of this application. Figure 5c This applies to scenarios where the first data collector is a network-side node, and the network-side node is different from the sensing node (e.g., UE or BS); in this scenario, the measurement target can be an active device or a passive device; specifically, it includes the following steps:

[0175] S5c-1: The sensing node sends a sensing reference signal.

[0176] S5c-2: The sensing node receives the echo signal and calculates the first sensing parameter. Optionally, the sensing node can also calculate the second auxiliary information corresponding to the first sensing parameter; the second auxiliary information includes at least one of the following: the quality indicator corresponding to the first sensing parameter, the timestamp corresponding to the first sensing parameter, and the relevant information corresponding to the first sensing parameter.

[0177] Optionally, before executing S5c-2, the network-side node can also send help information (such as a preset algorithm for the second auxiliary information) to the sensing node. This help information can be used by the sensing node to calculate the second auxiliary information (such as the quality indication corresponding to the first sensing parameter).

[0178] S5c-3: The sensing node sends the first sensing parameters to the network-side node. Optionally, the sensing node may also send the aforementioned second auxiliary information to the network-side node.

[0179] In some examples, in addition to sending the first sensing parameters to the network-side node, the sensing node can also send a third indication message to the network-side node. The third indication message is used to indicate that the first sensing parameters can be used as input information for the model in the model processing under the intelligent wireless sensing scenario.

[0180] S5c-4: The network-side node calculates the second sensing parameter based on the traditional sensing algorithm and the first sensing parameter. Optionally, the network-side node can also calculate the first auxiliary information corresponding to the second sensing parameter based on the second sensing parameter; the first auxiliary information may include at least one of the following: the quality indicator corresponding to the second sensing parameter, the timestamp corresponding to the second sensing parameter, and the relevant information corresponding to the second sensing parameter.

[0181] S5c-5: Network-side nodes store sensing data. The sensing parameters include a first sensing parameter and / or a second sensing parameter, and may also include at least one of the following: a quality indicator corresponding to the first sensing parameter, a timestamp corresponding to the first sensing parameter, relevant information corresponding to the first sensing parameter, a quality indicator corresponding to the second sensing parameter, a timestamp corresponding to the second sensing parameter, and relevant information corresponding to the second sensing parameter.

[0182] Based on the communication methods shown in S301 and S302 above, when the data collection party has insufficient sensing data, different data collection parties can transmit sensing data. The following are examples of some application scenarios.

[0183] Figure 6a This is another communication example diagram provided for an embodiment of this application. Figure 6a This applies to scenarios where both the first and second data collectors are sensing nodes (e.g., UEs), assuming UE 1 is the requester of sensing data and UE 2 is the provider of sensing data; specifically, it includes the following steps:

[0184] S6a-1: UE 1 sends a first sensing data request to UE 2. This first sensing data request may refer to the aforementioned first request or second request. The first sensing data request may include descriptive information about the sensing area (e.g., the extent of the sensing area). In some examples, any sensing area includes at least one sensing target.

[0185] Optionally, the first perception data request may also include fourth indication information, which is used to indicate whether UE1 needs to obtain the second perception parameters.

[0186] S6a-2: UE 2 filters the perception data stored by UE 2 according to the first perception data request to obtain perception data that meets the conditions.

[0187] S6a-3: UE 2 sends the aforementioned sensing data that meets the conditions to UE 1.

[0188] For example, when the fourth indication information is used to indicate that UE 1 does not need the second sensing parameter, the sensing data that meets the conditions includes the first sensing parameter but does not include the second sensing parameter. Optionally, the sensing data that meets the conditions may also include first auxiliary information; the first auxiliary information may include at least one of the following: a quality indication corresponding to the second sensing parameter, a timestamp corresponding to the second sensing parameter, and relevant information corresponding to the second sensing parameter.

[0189] For example, when the fourth indication information is used to indicate that UE 1 needs a second sensing parameter, the sensing data that meets the conditions includes the first sensing parameter and the second sensing parameter. Optionally, the sensing parameters that meet the conditions may also include first auxiliary information. Optionally, the sensing parameters that meet the conditions may also include second auxiliary information; the second auxiliary information includes at least one of the following: a quality indication corresponding to the first sensing parameter, a timestamp corresponding to the first sensing parameter, and relevant information corresponding to the first sensing parameter.

[0190] For example, when the first sensing data request does not include the fourth indication information, UE 2 can decide whether to send the second sensing parameter. Therefore, the sensing data that meets the conditions can include only: the first sensing parameter and the second auxiliary information; or it can include: the first sensing parameter, the second sensing parameter, the first auxiliary information, and the second auxiliary information. In other words, UE 2 sends multiple sensing data, and this example does not make a uniform provision on whether the sensing data includes the second sensing parameter.

[0191] In some examples, the qualified sensing data is carried in a third message. This third message may include a measurement field field indicating the first sensing parameter; a ground-truth label field indicating the second sensing parameter; a first auxiliary information field indicating first auxiliary information related to the second sensing parameter; and a second auxiliary information field indicating second auxiliary information related to the first sensing parameter.

[0192] S6a-4: UE 1 stores perceived data.

[0193] Figure 6b This is another communication example diagram provided for an embodiment of this application. Figure 6b This applies to scenarios where the first data collector and the second data collector are a sensing node (e.g., a UE) and a network-side node, respectively, and specifically includes the following steps:

[0194] S6b-1: The sensing node sends a second sensing data request to the network-side node. This second sensing data request may refer to either the first or second request mentioned above. The second sensing data request may include descriptive information about the sensing area (e.g., the extent of the sensing area). In some examples, any sensing area includes at least one sensing target.

[0195] Optionally, the second sensing data request may also include a fifth indication, which indicates whether the sensing node needs to acquire the second sensing parameters.

[0196] S6b-2: The network-side node filters the sensing data stored by the network-side node according to the second sensing data request to obtain sensing data that meets the conditions.

[0197] S6b-3: Network-side nodes send sensing data that meets the conditions to sensing nodes.

[0198] For example, when the fifth indication information is used to indicate that the sensing node does not need the second sensing parameter, the sensing data that meets the conditions includes the first sensing parameter but does not include the second sensing parameter. Optionally, the sensing data that meets the conditions may also include first auxiliary information; the first auxiliary information may include at least one of the following: a quality indication corresponding to the second sensing parameter, a timestamp corresponding to the second sensing parameter, and relevant information corresponding to the second sensing parameter.

[0199] For example, when the fifth indication information is used to indicate that the sensing node needs a second sensing parameter, the sensing data that meets the conditions includes both the first and second sensing parameters. Optionally, the sensing parameters that meet the conditions may also include first auxiliary information. Optionally, the sensing parameters that meet the conditions may also include second auxiliary information; the second auxiliary information includes at least one of the following: a quality indication corresponding to the first sensing parameter, a timestamp corresponding to the first sensing parameter, and relevant information corresponding to the first sensing parameter.

[0200] For example, when the second sensing data request does not include the fifth indication information, the network-side node can decide whether to send the second sensing parameter information. Therefore, the sensing data that meets the conditions can include only: the first sensing parameter and the second auxiliary information; or it can include: the first sensing parameter, the second sensing parameter, the first auxiliary information, and the second auxiliary information. In other words, the network-side node sends multiple sensing data, and this example does not make a uniform rule on whether the sensing data includes the second sensing parameter.

[0201] In some examples, the qualified sensing data is carried in a fourth message.
