[0002] The present application relates to the field of communication technology, in particular to a wireless sensing method and a communication device. BACKGROUND

[0003] In a sensing system, a sensing node utilizes a wireless sensing technology to sense a target in an environment, so as to realize human body existence detection, distance detection, position monitoring, activity recognition and health monitoring, etc.

[0004] However, the above sensing process has the problem of low sensing efficiency. How to improve the sensing efficiency is a problem to be solved. SUMMARY

[0005] In order to solve the above technical problems, the present application provides a wireless sensing method and a communication device, which can improve the sensing efficiency. In order to achieve the above purpose, the present application adopts the following technical solutions:

[0006] In a first aspect, a wireless sensing method is provided. The method can be executed by a first sensing node. The first sensing node can be the first sensing node itself, a component (such as a processor, a chip, or a chip system, etc.) in the first sensing node, or a logic module or software capable of realizing all or part of the functions of the first sensing node. In the following, the execution subject is taken as the first sensing node for example. The method comprises:

[0007] The first sensing node receives first range information, the first range information indicating a range where a first target is located. The first sensing node performs sensing measurement on the first target according to the first range information.

[0008] That is, the first sensing node first acquires a rough range where the first target is located, i.e. the first range information, and then performs accurate sensing measurement on the first target based on the first range information. Compared with the way of directly performing sensing measurement on the first target without acquiring the first range information, the sensing measurement of the present application is more targeted, the sensing measurement accuracy is higher, and the invalid range coverage of the signal and the interference of the invalid range reflection signal can be reduced, thereby improving the sensing efficiency.

[0009] In one possible design, the first range information is carried in a first frame, and the first frame is used to transmit a sensing measurement request.

[0010] For example, the first frame is a sensing measurement request frame. That is, the first sensing node receives the first range information in a sensing measurement session setup phase.

[0011] For example, the first frame is a sensing configuration frame. That is, the first sensing node receives the first range information in a sensing configuration phase.

[0012] In one possible design, the first frame includes a first field, and the first field includes the first range information.

[0013] For example, the first frame is a sensing configuration frame. The first field is a sensing target range information field.

[0014] In one possible design, the first frame includes a second field, and the second field includes the first range information.

[0015] For example, the first frame is a sensing measurement request frame. The second field is a sensing measurement parameter subfield in a sensing measurement parameter element field. Alternatively, the second field is a trigger-based TB sensing specific subelement subfield in a sensing subelement field. Alternatively, the second field is a non-TB sensing specific subelement subfield in the sensing subelement field.

[0016] In one possible design, the first frame further includes at least one of the following fields: a category, a public action, a dialog token, sensing answer information, or a measurement session identification indication.

[0017] In one possible design, the first sensing node performs sensing measurement on the first target according to the first range information, including that the first sensing node transmits and / or receives a first signal for sensing measurement on the first target according to the first range information.

[0018] That is, the first sensing node performs transceiving parameter adjustment according to the first range information, and then transceives the first signal using the adjusted transceiving parameter, so that the first signal is more suitable for sensing measurement on the first target, which helps to improve sensing accuracy and sensing efficiency.

[0019] In one possible design, the first sensing node transmits the first signal according to the first range information, including that the first sensing node determines a transmission parameter of the first signal according to the first range information, and transmits the first signal according to the transmission parameter of the first signal.

[0020] In a possible design, the first awareness node receives the first signal according to the first range information, including: determining a reception parameter of the first signal according to the first range information, and receiving the first signal according to the reception parameter of the first signal.

[0021] In a possible design, corresponding to the first awareness node transmitting the first signal according to the first range information, the method further includes: the first awareness node transmitting a reception parameter of the first signal, where the reception parameter of the first signal is determined according to the first range information, to enable other awareness nodes to receive the first signal according to the reception parameter of the first signal.

[0022] In a possible design, corresponding to the first awareness node receiving the first signal according to the first range information, the method further includes: the first awareness node transmitting a transmission parameter of the first signal, where the transmission parameter of the first signal is determined according to the first range information, to enable other awareness nodes to transmit the first signal according to the transmission parameter of the first signal.

[0023] In a possible design, the transmission parameter of the first signal includes at least one of: a transmission bandwidth of the first signal, a frequency range of the first signal, a transmission power of the first signal, a duration of continuous transmission of the first signal, a transmission period of the first signal, or a transmission beam angle of the first signal.

[0024] In a possible design, the reception parameter of the first signal includes at least one of: automatic gain control (AGC) or a reception beam angle of the first signal.

[0025] In a possible design, the method further includes: the first awareness node transmitting a first awareness result, where the first awareness result is determined according to the first signal, and the first awareness result indicates a location of the first target.

[0026] That is, after the first awareness node performs the awareness measurement on the first target, the first awareness node can further report the first awareness result, thereby implementing cooperative awareness.

[0027] In a possible design, the method further includes: the first awareness node receiving first information, where the first information indicates a type of an awareness task of performing the awareness measurement on the first target.

[0028] The first awareness node performs the awareness measurement on the first target according to the first range information, including: the first awareness node performing the awareness measurement on the first target according to the first range information and the type of the awareness task.

[0029] For example, the sensing task type includes a first task type. The first task type can include a large-magnitude disturbance task such as fall detection, large motion recognition, and the like, and the first range information indicates that the first target is located in a relatively close range. In this case, the first sensing node can use a smaller transmission power to transmit the first signal or use a smaller AGC to receive the first signal, to implement sensing measurement of the first target and prevent saturation of a receiver, thereby improving sensing performance.

[0030] For another example, the sensing task type includes a second task type. The second task type can include a small-magnitude disturbance task such as breathing and heartbeat monitoring, weak signal presence detection, and the like, and the first range information indicates that the first target is located in a relatively far range. In this case, the first sensing node can use a larger transmission power to transmit the first signal or use a larger AGC to receive the first signal, to implement sensing measurement of the first target and improve signal-to-noise ratio, thereby improving sensing performance.

[0031] In a possible design, the first range information is based on location information of a first reference point, and the method further includes: receiving, by the first sensing node, the location information of the first reference point.

[0032] The first sensing node performs sensing measurement on the first target according to the first range information, including: the first sensing node performs sensing measurement on the first target according to the first range information and the location information of the first reference point.

[0033] For example, the first sensing node adjusts a transmission parameter such as transmission power and transmission beam angle of the first signal according to the first range information and the location information of the first reference point, to improve signal-to-noise ratio of the first signal and achieve better sensing performance.

[0034] For another example, the first sensing node adjusts a reception parameter such as AGC and reception beam angle of the first signal according to the first range information and the location information of the first reference point, to achieve better sensing performance.

[0035] In a possible design, the method further includes: receiving, by the first sensing node, movement speed information of the first target.

[0036] The first sensing node performs sensing measurement on the first target according to the first range information, including: the first sensing node performs sensing measurement on the first target according to the first range information and the movement speed information of the first target.

[0037] For example, the first awareness node adjusts a transceiving parameter of the first signal, such as a transmitting beam angle or a receiving beam angle, according to the first range information and the moving speed information of the first target, so as to continuously perform the awareness measurement on the first target and achieve better awareness performance.

[0038] In a possible design, the method further includes: the first awareness node receiving first confidence information, the first confidence information indicating a probability that the range where the first target is located is the first range information.

[0039] The first awareness node performing the awareness measurement on the first target according to the first range information includes: the first awareness node performing the awareness measurement on the first target according to the first range information and the first confidence information.

[0040] For example, in a case where the first confidence information is greater than a first threshold, the first awareness node performs the awareness measurement on the first target according to the first range information, so as to improve target awareness efficiency.

[0041] For another example, in a case where the first confidence information is less than or equal to the first threshold, the first awareness node does not need to perform the awareness measurement on the first target according to the first range information, i.e., the first awareness node does not perform the awareness measurement process on the first target, so as to reduce unnecessary signal resource overhead.

[0042] The first threshold can be 0.6, 0.6 or 0.75, etc.

[0043] In a second aspect, a wireless awareness method is provided. The method can be performed by a second awareness node. The second awareness node can be the second awareness node itself, a component (for example, a processor, a chip, or a chip system, etc.) in the second awareness node, or a logic module or software that can realize all or part of the functions of the second awareness node. Hereinafter, the execution subject is taken as the second awareness node for example. The method includes:

[0044] The second awareness node receives first range information, the first range information indicating a range where a first target is located. The second awareness node obtains a second awareness result. The second awareness node selects a third awareness result from the second awareness result according to the first range information, the third awareness result indicating an awareness result corresponding to the first range information. The second awareness node sends the third awareness result.

[0045] That is, the second perception node first acquires a rough range where the first target is located, i.e., the first range information, and then selects and feeds back the third perception result based on the first range information. Since the third perception result includes the perception result corresponding to the first range information, the application can not only accurately feed back the target perception result and improve the perception feedback efficiency, but also help reduce the complexity of subsequent perception data association or perception fusion and improve the perception efficiency.

[0046] In addition, since the third perception result is selected from the second perception result, the application can also reduce the feedback amount and save resource overhead.

[0047] In a possible design, the first range information is carried in a first frame, and the first frame is used to transmit a perception measurement request.

[0048] For example, the first frame is a perception measurement request frame. That is, the first perception node receives the first range information in a perception measurement session establishment stage.

[0049] For another example, the first frame is a perception configuration frame. That is, the first perception node receives the first range information in a perception configuration stage.

[0050] In a possible design, the second perception node acquires the second perception result, including that the second perception node performs perception measurement to obtain the second perception result.

[0051] That is, the second perception result is obtained by the second perception node performing perception measurement.

[0052] In a possible design, the method further includes that the second perception node receives first information, and the first information indicates a perception task type of performing perception measurement on the first target.

[0053] The second perception node selects the third perception result from the second perception result according to the first range information, including that the second perception node selects the third perception result from the second perception result according to the first range information and the perception task type.

[0054] For example, the perception task type includes a first task type. The first task type can include a large-magnitude disturbance task such as fall detection and large-motion recognition. In this case, the second perception node selects measurement data with a larger signal amplitude from the second perception result as the third perception result according to the first range information, thereby helping to improve the accuracy of the perception result.

[0055] For another example, the perception task type includes a second task type. The second task type can include a small-amplitude perturbation task such as respiration heartbeat monitoring, weak signal existence detection, etc. In this case, the second perception node selects, as the third perception result, measurement data with a smaller signal amplitude from the second perception result according to the first range information, thereby helping to improve the accuracy of the perception result.

[0056] In a possible design, the first range information is based on position information of a first reference point, and the method further includes: receiving, by the second perception node, the position information of the first reference point.

[0057] The second perception node selects the third perception result from the second perception result according to the first range information, including: the second perception node selects the third perception result from the second perception result according to the first range information and position information of the first reference point.

[0058] For example, the second perception node determines a range between the second perception node and the first target according to the position information of the first reference point and the first range information, and selects, as the third perception result, measurement data corresponding to the range between the second perception node and the first target from the second perception result according to the range between the second perception node and the first target, thereby helping to improve the accuracy of the perception result.

[0059] In a possible design, the method further includes: receiving, by the second perception node, movement speed information of the first target.

[0060] The second perception node selects the third perception result from the second perception result according to the first range information, including: the second perception node selects the third perception result from the second perception result according to the first range information and movement speed information of the first target.

[0061] For example, the second perception node determines a range between the second perception node and the first target according to the movement speed information of the first target and the first range information, and selects, as the third perception result, measurement data corresponding to the range between the second perception node and the first target from the second perception result according to the range between the second perception node and the first target, thereby helping to improve the accuracy of the perception result.

[0062] In a possible design, the method further includes: receiving, by the second perception node, first confidence information, where the first confidence information indicates a probability that the range in which the first target is located is the first range information.

[0063] The second perception node selects a third perception result from the second perception result according to the first range information, including: the second perception node selects the third perception result from the second perception result according to the first range information and the first confidence information.

[0064] For example, in the case that the first confidence information is greater than the first threshold, the second perception node selects the third perception result from the second perception result according to the first range information, so as to improve the target perception efficiency.

[0065] For another example, in the case that the first confidence information is less than or equal to the first threshold, the second perception node does not need to select the third perception result from the second perception result according to the first range information, that is, the second perception node does not perform the selection and feedback process of the third perception result, so as to reduce unnecessary resource overhead.

[0066] The first threshold can be 0.6, 0.6, or 0.75, etc.

[0067] In a third aspect, a wireless perception method is provided. The method can be performed by a third perception node. The third perception node can be the third perception node itself, a component (for example, a processor, a chip, or a chip system, etc.) in the third perception node, or a logic module or software that can realize all or part of the functions of the third perception node. In the following, the execution subject is taken as an example for description. The method includes:

The third perception node sends the first range information, and the first range information is used for perception measurement of the first target.

[0069] In a possible design, the first range information is carried in a first frame, and the first frame is used for transmission of a perception measurement request.

[0074] In a possible design, the reception parameter of the first signal includes at least one of the following: automatic gain control (AGC) or a reception beam angle of the first signal.

[0075] In a possible design, the method further includes: the third sensing node transmitting first information, movement speed information of the first target, location information of a first reference point, or first confidence information.

[0076] The first information indicates a sensing task type of a sensing measurement on the first target, the first confidence information indicates a probability that a range in which the first target is located is the first range information, and the first range information is based on the location information of the first reference point.

[0078] That is, the first range information can be obtained through autonomous sensing measurement by the third sensing node, or can be obtained from another device, for example, an image acquisition device.

[0079] The technical effects brought by any design in the third aspect can be referred to the technical effects brought by different designs in the first aspect, the second aspect or the fourth aspect, which will not be repeated here.

[0080] In a fourth aspect, a wireless sensing method is provided. The method can be performed by a sensing center. The sensing center can be the sensing center itself, a component (for example, a processor, a chip, or a chip system) in the sensing center, or a logic module or software that can realize all or part of the functions of the sensing center. In the following, the sensing center is taken as an example for description. The method includes:

[0081] The perception center receives first range information, the first range information indicating a range where a first target is located. The perception center determines a second parameter according to the first range information, the second parameter including a transmission parameter and / or a reception parameter of a first signal, the first signal being used for perception measurement of the first target. The perception center transmits the second parameter.

[0082] That is, the perception center first acquires a rough range where the first target is located, i.e., the first range information, and then performs parameter adjustment based on the first range information to obtain the second parameter. The second parameter is a parameter for accurate perception measurement of the first target, so that other perception nodes can perform accurate perception measurement of the first target based on the second parameter, thereby reducing the computation amount of the perception nodes. In terms of the node performing the perception measurement of the first target, compared with the way of directly performing perception measurement on the first target without acquiring the first range information and the second parameter, the application can make the perception measurement more targeted and more accurate, and can also reduce the invalid range coverage of the signal and the interference of the invalid range reflection signal, thereby improving the perception efficiency.

[0083] In a possible design, the first range information is carried in a first frame, and / or the second parameter is carried in the first frame, the first frame being used for transmission of a perception measurement request.

[0084] For example, the first frame is a perception measurement request frame. That is, the perception center receives the first range information and / or transmits the second parameter in a perception measurement session establishment stage.

[0085] For another example, the first frame is a perception configuration frame. That is, the perception center receives the first range information and / or transmits the second parameter in a perception configuration stage.

[0086] In a possible design, the method further includes: the perception center receiving first information, the first information indicating a perception task type of the perception measurement on the first target.

[0087] The perception center determining the second parameter according to the first range information includes: the perception center determining the second parameter according to the first range information and the perception task type.

[0088] For example, the sensing task type includes a first task type. The first task type can include a large-magnitude disturbance task such as fall detection, large motion recognition, and the like, and the first range information indicates that the first target is located in a relatively close range. In this case, the sensing center can adjust the second parameter, for example, in the second parameter, the first signal has a smaller transmission power, or the first signal has a smaller automatic gain control (AGC), so that other sensing nodes can perform sensing measurement on the first target, and receiver saturation can be prevented, thereby improving sensing performance.

[0089] For another example, the sensing task type includes a second task type. The second task type can include a small-magnitude disturbance task such as breathing and heartbeat monitoring, weak signal presence detection, and the like, and the first range information indicates that the first target is located in a relatively far range. In this case, the sensing center can adjust the second parameter, for example, in the second parameter, the first signal has a larger transmission power, or the first signal has a larger AGC, so that other sensing nodes can perform sensing measurement on the first target, and signal-to-noise ratio can be improved, thereby improving sensing performance.

[0090] In a possible design, the method further includes: receiving, by the sensing center, a first sensing result, the first sensing result being determined according to the first signal, and the first sensing result indicating a position of the first target.

[0091] That is, the sensing center can also obtain sensing results of other sensing nodes, thereby realizing cooperative sensing.

[0092] In a possible design, the first range information is based on position information of a first reference point, and the method further includes: receiving, by the sensing center, the position information of the first reference point.

[0093] The sensing center determines the second parameter according to the first range information, including: the sensing center determines the second parameter according to the first range information and the position information of the first reference point.

[0094] For example, the sensing center adjusts the second parameter according to the first range information and the position information of the first reference point.

[0095] The adjusted second parameter can include transmission power and / or transmission beam angle, thereby improving signal-to-noise ratio of the first signal and realizing better sensing performance.

[0096] Or, the adjusted second parameter can include AGC and / or reception beam angle, thereby enabling other sensing nodes to more accurately detect the first signal and realizing better sensing performance.

[0097] In a possible design, the method further includes: receiving, by the perception center, movement speed information of the first target.

[0098] Determining, by the perception center, the second parameter according to the first range information includes: determining, by the perception center, the second parameter according to the first range information and movement speed of the first target.

[0099] For example, the perception center adjusts a transceiving parameter of the first signal, such as a transmission beam angle or a reception beam angle, according to the first range information and the movement speed information of the first target, so that other perception nodes can continuously perform perception measurement on the first target based on the second parameter, and better perception performance is achieved.

[0100] In a possible design, the method further includes: receiving, by the perception center, first confidence information, the first confidence information indicating a probability that a range in which the first target is located is the first range.

[0101] Determining, by the perception center, the second parameter according to the first range information includes: determining, by the perception center, the second parameter according to the first range information and the first confidence information.

[0102] For example, in a case where the first confidence information is greater than a first threshold, the perception center determines the second parameter according to the first range information, so as to improve target perception efficiency.

[0103] For another example, in a case where the first confidence information is less than or equal to the first threshold, the perception center does not need to determine the second parameter according to the first range information, that is, the perception center does not perform a process of determining and sending the second parameter, so as to reduce unnecessary signal resource overhead.

[0104] In a fifth aspect, a wireless perception method is provided. The method can be performed by a fourth perception node. The fourth perception node can be the fourth perception node itself, a component (for example, a processor, a chip, or a chip system) in the fourth perception node, or a logic module or software that can implement all or part of the functions of the fourth perception node. In the following, the execution subject is taken as the fourth perception node for example. The method includes:

[0105] The fourth perception node receives a second parameter, the second parameter being determined according to first range information, the first range information indicating a range in which a first target is located. The fourth perception node transmits or receives a first signal according to the second parameter, the first signal being used for perception measurement on the first target.

[0106] That is, the fourth sensing node first acquires the second parameter, and then performs accurate sensing measurement on the first target based on the second parameter. Since the second parameter is determined based on the first range information, and the first range information indicates the rough range where the first target is located, the sensing measurement performed by the fourth sensing node is more accurate. Compared with the way of directly performing sensing measurement on the first target without acquiring the first range information and the second parameter, the sensing measurement of the present application is more targeted, the sensing measurement accuracy is higher, and the invalid range coverage of the signal and the interference of the invalid range reflection signal can be reduced, thereby improving the sensing efficiency.

[0107] In addition, the fourth sensing node performs sensing measurement based on the received second parameter, so that the operation amount of the fourth sensing node is low.

[0108] In a possible design, the second parameter is carried in a first frame, and the first frame is used to transmit a sensing measurement request.

[0109] For example, the first frame is a sensing measurement request frame. That is, the fourth sensing node receives the second parameter in a sensing measurement session establishment stage.

[0110] For another example, the first frame is a sensing configuration frame. That is, the fourth sensing node receives the second parameter in a sensing configuration stage.

[0111] In a possible design, the method further includes: the fourth sensing node sends a first sensing result, the first sensing result being determined according to the first signal, and the first sensing result indicating the position of the first target.

[0112] That is, after the fourth sensing node performs sensing measurement on the first target, the fourth sensing node can further report the first sensing result, thereby realizing cooperative sensing.

[0165] The above-mentioned communication systems applicable to the present application are only illustrative, and the communication systems applicable to the present application are not limited thereto. It is uniformly described here that the following will not be described again.

[0166] Fig. 1 is a schematic diagram of an architecture of a communication system to which embodiments of the present application are applied. As shown in Fig. 1, the communication system includes two communication nodes. The two communication nodes can communicate with each other through wired or wireless means.

[0167] In the present application, the communication nodes can be mobile nodes or fixed nodes. The communication device in the present application is a device with short-range wireless communication function. Some examples of short-range wireless communication are as follows: WiFi, Bluetooth, ZigBee, UWB, infrared radiation, etc.

[0168] By way of example, the communication nodes in the present application can be, but are not limited to, a mobile phone, a tablet computer, a notebook computer, a sound box, a wearable device, a mouse, a keyboard, a socket, a table lamp, a smart screen, a television, a smart home appliance, an internet of things (IoT) device, a camera device, etc.

[0170] The present application does not specifically limit the form of the communication nodes. It is easy to understand that a fixed node can be understood as a node whose position cannot be moved or a node whose position is not convenient to move, for example, a television can be understood as a fixed node.

[0171] Taking Fig. 1 as an example, the two communication nodes are denoted as a first communication node and a second communication node. The first communication node can be a perception center, and the second communication node can be a perception node. Alternatively, the first communication node can be one perception node, and the second communication node can be another perception node. Alternatively, the first communication node can be one perception center, and the second communication node can be another perception center.

[0172] The perception center is mainly responsible for the aggregation, storage, and calling of perception data. In addition, in the present application, the perception center can be described in other ways, such as a controller, a control center, etc. Hereinafter, the perception center is taken as an example for introduction.

[0173] The perception node mainly uses perception technology for perception.

[0174] In addition, taking the sensing measurement in the Starlink communication system as an example, the sensing center can be a grant node in the Starlink communication system, and the sensing node can be a terminal node in the Starlink communication system or a grant node.

[0175] In order to facilitate the understanding of the embodiments of the present application, the terms involved in the embodiments of the present application will be briefly described first. It should be understood that these descriptions are only for the purpose of facilitating the understanding of the embodiments of the present application, and should not constitute any limitation on the present application.

[0176] 1. Integrated sensing and communications (ISAC)

[0177] Integrated sensing and communications has gradually become one of the hotspots in the industry and academia. Based on the signal propagation characteristics between communication nodes, target (such as human body) can be effectively sensed by analyzing channel change information. Among them, the application scenarios of integrated sensing and communications are various, such as smart home, consumer electronics, industrial industry, intelligent manufacturing and other fields have broad prospects. And human existence detection, distance detection, position monitoring, activity recognition and health monitoring are all typical scenarios of integrated sensing and communications. With the popularization of the concept of integrated sensing and communications and the wide deployment of nodes, the mode of human sensing is also extended from single pair of nodes sensing by sensing nodes self-receiving and separating receiving and transmitting to multiple sensing nodes cooperating to sense targets. Different information observed by different sensing nodes can be effectively utilized to improve sensing diversity gain and sensing efficiency.

[0178] It should be pointed out that in the present application, the signal can be understood as the signal of the target in the sensing environment. The signal can be a communication signal, such as an orthogonal frequency division multiplexing (OFDM) signal. The signal can also be described as a sensing signal, a measurement signal, a sensing measurement signal, a sensing signal, an observation signal, a communication signal, a wireless signal, a radio signal, a radio frequency signal, a radio frequency signal, etc. In the present application, the signal is taken as an example for introduction.

[0179] 2. Sensing process

[0180] First, the roles in the sensing process are introduced:

[0181] A sensing initiator is a node that initiates sensing; a sensing responder is a node that responds to sensing initiated by the sensing initiator; a sensing transmitter is a node that transmits a sensing signal; and a sensing receiver is a node that receives the sensing signal transmitted by the sensing transmitter and performs sensing measurement.

[0182] For example, in FIG. 2a, the sensing initiator can be sensing node A, and the sensing responder can be sensing node B. Alternatively, the sensing initiator can be sensing node B, and the sensing responder can be sensing node A.

[0183] For example, in FIG. 2a, the sensing transmitter can be sensing node A, and the sensing receiver can be sensing node B. Alternatively, the sensing transmitter can be sensing node B, and the sensing receiver can be sensing node A.

[0184] Then, as shown in FIG. 2a, the sensing process involves the following stages:

[0185] 2-1, a sensing capabilities exchange stage: exchange of sensing capabilities of both parties is completed.

[0186] In this stage, the sensing capabilities of the opposite end are requested through a sensing capabilities request frame, and the sensing capabilities of the local end are fed back through a sensing capabilities response frame.

[0187] For example, the sensing initiator sends a sensing capabilities request frame to the sensing responder. The sensing capabilities request frame is used to request the sensing capabilities of the sensing responder. The sensing responder sends a sensing capabilities response frame to the sensing initiator. The sensing capabilities response frame indicates the sensing capabilities of the sensing responder.

[0188] 2-2, sensing measurement session establishment phase: sensing measurement parameters are negotiated by the sensing initiator and the sensing responder, and a sensing measurement session is established.

[0189] In this phase, sensing measurement is requested by a sensing measurement request frame, and sensing measurement request frame reception success is fed back by a sensing measurement response frame.

[0190] For example, the sensing initiator sends a sensing measurement request frame to the sensing responder. The sensing measurement request frame is used to request the sensing responder to perform sensing measurement. The sensing responder sends a sensing measurement response frame to the sensing initiator. The sensing measurement response frame indicates that the sensing measurement request frame is received successfully.

[0191] In addition, the sensing measurement request frame can also have other names, such as a sensing configuration frame. Similarly, the sensing measurement response frame can also have other names, such as a sensing configuration feedback frame.

[0192] 2-3, sensing measurement exchange phase: the actual measurement part of sensing, which is completed by the sensing transmitter sending a sensing signal to the sensing receiver to perform sensing measurement.

[0193] In this phase, sensing results are reported by a sensing result reporting frame. For example, the sensing receiver sends a sensing result reporting frame to the sensing transmitter. The sensing result reporting frame is used to report sensing results.

[0194] In addition, the sensing result reporting frame can also have other names, such as a sensing information reporting frame.

[0195] 2-4, sensing measurement session termination phase: used to terminate the sensing measurement session.

[0196] In this phase, the sensing measurement session is terminated by a sensing measurement termination frame. For example, the sensing initiator sends a sensing measurement termination frame to the sensing responder. The sensing measurement termination frame is used to indicate that the sensing measurement session is terminated.

[0197] In addition, the perception measurement closing frame can also have other names, such as a perception termination frame.

[0198] 3. Perception mode

[0199] In this application, the perception mode can include at least one of the following: self-transmitting and self-receiving, transmitting and receiving separation, or cooperative perception.

[0200] 3-1. Self-transmitting and self-receiving

[0201] Self-transmitting and self-receiving is a perception mode in perception technology. The self-transmitting and self-receiving perception mode, which can also be referred to as single-base perception or single-station perception, can be denoted as Mono-static sensing. In this application, self-transmitting and self-receiving is taken as an example for introduction.

[0202] Exemplarily, the processing procedure of the self-transmitting and self-receiving perception mode is introduced as follows:

[0203] As shown in FIG. 2b, the perception node transmits a signal, the signal encounters a target (such as a human body) in the environment and is reflected, the perception node receives the reflected signal, and the position of the target is determined based on the reflected signal.

[0204] 3-2. Transmitting and receiving separation

[0205] Transmitting and receiving separation is another perception mode in perception technology. Taking two perception nodes as an example, the transmitting and receiving separation perception mode, which can also be referred to as A transmitting and B receiving or bi-static sensing, can be denoted as Bi-static sensing. In this application, transmitting and receiving separation is taken as an example for introduction.

[0206] Exemplarily, the processing procedure of the transmitting and receiving separation perception mode is introduced as follows:

[0207] At the transmitting end, the perception node transmits a signal, the signal encounters a target (such as a human body) in the environment and is reflected. At the receiving end, the perception node receives the reflected signal, and the position of the target is determined based on the reflected signal. The transmitting end and the receiving end correspond to different perception nodes, or the transmitting end is a perception node and the receiving end is a perception center, or the transmitting end is a perception center and the receiving end is a perception node.

[0208] For example, in the smart home scenario, electronic devices (such as mobile phones, tablets, laptops, sound boxes, sockets, table lamps, televisions, smart home appliances, cameras, etc.) in the room can serve as sensing nodes to monitor the presence, location, motion activity, vital signs, and health status of the human body, and provide all-round intelligent sensing for the human body. In FIG. 2b and FIG. 2c, taking the sensing nodes in the room monitoring the respiration, body movement, and sleep state of the human body during sleep at night as an example, an introduction is made. Among them, the sensing nodes in the room can perform sensing based on the self-transmitting and self-receiving sensing mode, or can perform sensing based on the transmitting-receiving separation sensing mode.

[0209] 3-3, Cooperative sensing

[0210] Cooperative sensing is another sensing mode in sensing technology. Cooperative sensing refers to multiple sensing nodes cooperating to perform target sensing. By scheduling multiple sensing nodes for cooperative sensing, not only the sensing information of a single pair or a single sensing node can be utilized, but also the observation diversity gain of multiple sensing nodes can be combined to improve the overall sensing performance. For example, multiple sensing nodes are deployed in a region, and multiple sensing nodes jointly monitor the activity of a target, each node monitors the target from a different angle and direction, and the monitored data is associated and / or fused, thereby improving the sensing effect.

[0211] For example, for a human body monitoring application scenario, each sensing node measures the distance information between itself and the human body, and multiple sensing nodes cooperate to perform two-dimensional or even three-dimensional positioning and tracking of the human body, thereby improving the accuracy of positioning and tracking.

[0212] For example, for a human body respiration monitoring application scenario, multiple sensing nodes monitor the respiration of the human body, and the respiration information measured by each sensing node is fused, thereby improving the respiration monitoring accuracy.

[0213] It should be noted that in this application, in the cooperative sensing mode, a certain sensing node can act as a central node for scheduling, that is, a certain sensing node plays the role of a sensing center, thereby realizing cooperative sensing.

[0214] It should be noted that in this application, cooperative sensing can include the self-transmitting and self-receiving sensing mode, or can include the transmitting-receiving separation sensing mode, as shown in FIG. 2d and FIG. 2e.

[0215] In FIG. 2d, three sensing nodes are deployed in a region, denoted as sensing node A, sensing node B, and sensing node C. Each node transmits and receives signals through the self-transmitting and self-receiving mode to realize human body monitoring and positioning.

[0216] In FIG. 2e, three sensing nodes are deployed in a region, denoted as sensing node A, sensing node B, and sensing node C. Each node transmits and receives signals in a transceiver separation mode, achieving human body monitoring and positioning. For example, the signal transmitted by sensing node A is reflected by the human body and received by sensing node B. The signal transmitted by sensing node B is reflected by the human body and received by sensing node C. The signal transmitted by sensing node C is reflected by the human body and received by sensing node A.

[0217] 4-1, Data association

[0218] In this application, data association can be understood as the same target sensed by different sensing nodes is labeled.

[0219] For example, two sensing nodes are deployed in a room, denoted as sensing node 1 and sensing node 2, and the two sensing nodes sense respectively. Among them, sensing node 1 senses three targets in the room, namely human body 1, human body 2 and human body 3 in the room, denoted as target A1, target A2 and target A3. Sensing node 2 senses two targets in the room, namely human body 1 and human body 2 in the room, denoted as target B1 and target B2. That is, target A1 and target B1 correspond to the same target in the real environment, namely human body 1 in the room. Target A1 and target B1 can be labeled as the same target. Target A2 and target B2 correspond to the same target in the real environment, namely human body 2 in the room. Target A2 and target B2 can be labeled as the same target.

[0220] In addition, data association can also be described as data association processing, association processing, or association. In this application, data association is taken as an example for introduction.

[0221] 4-2, Data fusion

[0222] In this application, data fusion can be understood as integrating different information of the same target sensed by different sensing nodes.

[0223] The data fusion can include at least one of data level fusion, feature level fusion, or result level fusion. The data level refers to original perception data, such as channel state information (CSI) obtained by a perception node through perception measurement, channel impulse response (CIR) information, and the like. The feature level refers to statistical results used to describe features of a perception target in original perception data, such as a peak value in CIR, a number of peaks in CIR, and the like. The result level refers to a perception result of a perception target, such as a position, an angle, and the like. The data level fusion, the feature level fusion, and the result level fusion can be referred to related technical specifications, and will not be described herein.

[0224] For the result level fusion, two perception nodes are taken as examples, which are referred to as perception node 1 and perception node 2, and the two perception nodes perform perception respectively. The perception node 1 perceives a position of a target A1. The perception node 2 perceives a moving speed of the target A1. Different information of the target A1 can be fused, and the fused information includes the position and the moving speed of the target A1.

[0225] In addition, the data fusion can also be described as data fusion processing, fusion processing, perception fusion, or fusion, and the like. In this application, the data fusion is taken as an example for description.

[0226] For example, in the smart home scenario, a perception center and perception nodes can be deployed, as shown in FIG. 2f. The perception center can be one, and the perception nodes can be multiple. At time 2, the perception node A, the perception node B, and the perception node C perform perception measurement on a human body to obtain perception measurement data. Then, the perception node A, the perception node B, and the perception node C send the obtained perception measurement to the perception center, so that the perception center processes the perception measurement data from different perception nodes, such as performing data association or data fusion, to obtain a perception result of the human body.

[0227] That is, in the related art, a target in an environment can be perceived through perception measurement based on the above perception modes, such as self-receiving, receiving and transmitting separation, or cooperative perception, to obtain perception measurement data. The perception measurement data can be processed based on the above data processing modes, such as data association, data fusion, and the like, to obtain a perception result of the target in the environment.

[0228] However, in the above perception process, there is a problem of low perception efficiency.

[0229] Therefore, the application provides a wireless sensing method. The method can be applied to the system shown in FIG. 1, etc. In the following, the wireless sensing method proposed by the embodiment of the application is described in detail in combination with FIG. 3. The wireless sensing method 300 proposed by the embodiment of the application includes the following operations:

[0230] S301, the sensing node 1 determines the first range information.

[0231] The sensing node 1 can be a communication node in FIG. 1, such as a first communication node, and the first communication node serves as the sensing node.

[0232] The first range information indicates the range where the first target exists. Exemplarily, the first target can be a human body in a monitored environment. Exemplarily, the first range information includes the identification of the first target and the range where the first target exists.

[0233] Optionally, the first range information indicates the distance range where the first target exists.

[0234] Exemplarily, the first range information includes a first distance value and a second distance value, which indicate the distance range where the first target exists. The first distance value is the minimum value of the distance range, and the second distance value is the maximum value of the distance range. It can be understood that the first distance value and the second distance value are the endpoint values of the above distance range (i.e. the distance range where the first target exists). Alternatively, the first distance value is the center value of the distance range, and the second distance value is the difference between the center value of the distance range and the endpoint value of the distance range.

[0235] It should be pointed out that in the present application, the distance range where the first target exists is determined based on a relative coordinate system. The origin of the relative coordinate system can be described as the first reference point. The first reference point can be a position known by both the sensing node 1 and the sensing node 2. For example, the first reference point can be the position of the sensing node 1, the position of the sensing node 2, or a position in the environment, which is not limited. The x-axis of the relative coordinate system can be the positive east direction, the y-axis of the relative coordinate system can be the positive north direction, and the z-axis of the relative coordinate system can be the direction perpendicular to the earth ellipsoid. That is, the first range information is based on the position information of the first reference point.

[0236] Based on this, in some embodiments, the first distance value can be understood as the closest distance of the first target relative to the first reference point. The second distance value can be understood as the farthest distance of the first target relative to the first reference point. For example, as shown in FIG. 4a, the first range information is denoted as [a, b]. Wherein a represents the closest distance of the first target relative to the first reference point, and b represents the farthest distance of the first target relative to the first reference point.

[0237] Based on this, in some embodiments, the first distance value can be understood as a distance between the center point of the first target and the first reference point. The second distance value can be understood as a distance between the edge of the first target and the center point of the first target. For example, as shown in FIG. 4a, the first range information is denoted as [c, Δ]. Wherein, c represents a distance between the center point of the first target and the first reference point, and Δ represents a distance between the edge of the first target and the center point of the first target.

[0238] Optionally, the first range information indicates an angle range in which the first target is located.

[0239] For example, the first range information includes a first angle and a second angle, and the first angle and the second angle indicate an angle range in which the first target is located. Wherein, the first angle is a minimum value of the angle range, and the second angle is a maximum value of the angle range. It can be understood that the first angle and the second angle are end point values of the angle range (i.e. the angle range in which the first target is located). Alternatively, the first angle is a central value of the angle range, and the second angle is a difference value between the central value of the angle range and an end point value of the angle range.

[0240] It should be noted that, in this application, the first angle includes an angle of the first direction and / or an angle of the second direction. Wherein, the first direction can be a horizontal direction, and correspondingly, the first angle can be understood as an azimuth angle. The second direction can be a vertical direction, and correspondingly, the first angle can be understood as a pitch angle.

[0241] It should be noted that, in this application, the angle range in which the first target is located is determined based on a relative coordinate system, which can be referred to in the foregoing paragraphs and will not be described again. That is, the first range information is based on the position information of the first reference point.

[0242] Based on this, in some embodiments, taking the horizontal direction as an example, the first angle can be understood as a minimum azimuth angle of the first target relative to the first reference point. The second angle can be understood as a maximum azimuth angle of the first target relative to the first reference point. For example, as shown in FIG. 4b, the first range information is denoted as [α, β]. Wherein, α represents a minimum azimuth angle of the first target relative to the first reference point, and β represents a maximum azimuth angle of the first target relative to the first reference point.

[0243] Based on this, in some embodiments, taking the horizontal direction as an example, the first angle can be understood as a minimum azimuth angle of the first target relative to the first reference point. The second angle can be understood as a maximum azimuth angle of the first target relative to the first reference point. For example, as shown in FIG. 4b, the first range information is denoted as [α, β]. Wherein, α represents a minimum azimuth angle of the first target relative to the first reference point, and β represents a maximum azimuth angle of the first target relative to the first reference point.

[0244] Based on this, in some embodiments, taking the vertical direction as an example, the first angle can be understood as the minimum pitch angle of the first target relative to the first reference point. The second angle can be understood as the maximum pitch angle of the first target relative to the first reference point. For example, the first range information is recorded as [a, b]. Wherein a represents the minimum pitch angle of the first target relative to the first reference point, and b represents the maximum pitch angle of the first target relative to the first reference point.

[0245] Based on this, in some other embodiments, taking the vertical direction as an example, the first angle can be understood as the pitch angle of the center point of the first target relative to the first reference point. The second angle can be understood as the angle of the edge of the first target relative to the center point of the first target. For example, the first range information is recorded as [g, D]. Wherein g represents the pitch angle of the center point of the first target relative to the first reference point, and D represents the angle of the edge of the first target relative to the center point of the first target.

[0246] Optionally, the first range information indicates one or more of the longitude range, the latitude range and the height range where the first target is located.

[0247] It should be pointed out that in the present application, the longitude range, the latitude range and the height range where the first target is located are determined based on the absolute coordinate system.

[0248] Exemplarily, taking the Beidou coordinate system as an example, for the field of the longitude range, the field is positive east longitude, and the field is negative west longitude. For the field of the latitude range, the field is positive north latitude, and the field is negative south latitude. For the field of the altitude range, the field is positive above the reference plane, and the field is negative below the reference plane.

[0249] It should be pointed out that in the present application, taking the relative coordinate system as an example, the first range information can indicate the distance range and / or the angle range where the first target is located. Taking the absolute coordinate system as an example, the first range information can indicate at least one of the longitude range, the latitude range and the height range where the first target is located.

[0250] Optionally, the implementation process of S301 comprises: the perception node 1 determines the first range information through perception measurement. That is, the perception node 1 autonomously acquires the first range information. In the process of acquiring the first range information, the perception mode of the perception measurement performed by the perception node 1 can be one of the following: self-receiving, receiving and transmitting separation, or cooperative perception. The perception measurement in the receiving and transmitting separation mode can be performed by the perception node 1 and the perception node 2, or by the perception node 1 and other perception nodes (nodes other than the perception node 1 and the perception node 2), and the perception node 2 can be seen in the introduction of S302, which will not be described here. Similarly, the perception measurement in the cooperative perception mode can be performed by the perception node 1 and the perception node 2, or by the perception node 1 and other perception nodes (nodes other than the perception node 1 and the perception node 2), which is not limited.

[0251] Taking FIG. 2f as an example, the perception node 1 can be the perception node A in FIG. 2f, and the first target is a human body. At time 2, the human body is located 0.2 meters in front of the perception node A, and the perception node A performs perception measurement on the human body to obtain the first range information. The first range information indicates the position of the human body, such as being located 0.2 meters in front of the perception node A.

[0252] Optionally, the implementation process of S301 comprises: the perception node 1 receives the first range information.

[0253] For example, the perception node 1 acquires the first range information from other nodes. For example, the perception node 1 acquires the first range information from an image acquisition device. The image acquisition device can include a camera, etc., and the image acquisition device can acquire images in the environment and determine the first range information based on the images. The image acquisition device sends the first range information to the perception node 1. Correspondingly, the perception node 1 receives the first range information from the image acquisition device. Alternatively, an infrared sensor sends the first range information to the perception node 1. Correspondingly, the perception node 1 receives the first range information from the infrared sensor.

[0254] In addition, the image acquisition device and the infrared sensor can also be arranged on the perception node 1, such as the perception node 1 being a mobile phone, the image acquisition device being a camera on the mobile phone, and the infrared sensor being a sensor on the mobile phone. In this case, it can be understood that the perception node 1 acquires the first range information through the image acquisition device, or the perception node 1 acquires the first range information through the infrared sensor, which is not limited in the present application.

[0255] For another example, the perception node 1 acquires the first range information from a positioning device. The positioning device can be a global positioning system (GPS) or the like. The positioning device collects the first range information of the first target and then sends the first range information to the perception node 1. Correspondingly, the perception node 1 receives the first range information from the positioning device. In addition, the positioning device can also be arranged on the perception node 1. In this case, it can be understood that the perception node 1 acquires the first range information through the positioning device.

[0256] For another example, the perception node 1 includes an input device. The input device includes a touch screen, a keyboard or the like. The user can input the first range information through the touch screen, the keyboard or the like to make the perception node 1 acquire the first range information.

[0257] It can be easily understood that in the present application, S301 can be understood as a rough range acquisition stage. That is, the rough range where the first target is located is acquired, thereby laying a foundation for accurate measurement.

[0258] For the perception node 1, after the perception node 1 determines the first range information, S302 is performed:

[0259] S302, the perception node 1 sends the first range information to the perception node 2. Correspondingly, the perception node 2 receives the first range information from the perception node 1.

[0260] The perception node 1 can refer to the introduction of S301 and will not be repeated here.

[0261] The perception node 2 can be another communication node in FIG. 1, such as a second communication node, and the second communication node serves as a perception node.

[0262] For example, the perception node 1 can be the perception node A in FIG. 2f, the perception node 2 can be the perception node B in FIG. 2f, and the first target is a human body. The perception node B receives the first range information from the perception node A. The first range information indicates the position of the human body, such as being located in the living room or being located 0.2 meters in front of the perception node A.

[0263] It can be understood that in the case that the perception node 1 and the perception node 2 are different perception nodes, S302 can include that the perception node 1 sends the first range information to the perception node 2 through the perception center 1. Correspondingly, the perception node 2 receives the first range information from the perception node 1 through the perception center 1.

[0264] For example, in FIG. 2f, the perception node 1 can be the perception node A in FIG. 2f, the perception node 2 can be the perception node B in FIG. 2f, the perception center 1 can be the perception center in FIG. 2f, and the first target can be a human body. For example, at time 2, the perception node A sends the first range information to the perception center. After receiving the first range information from the perception node A, the perception center sends the first range information to the perception node B. The first range information indicates the position of the human body, such as being in the living room or being 0.2 meters in front of the perception node A.

[0265] For example, the first frame is a perception configuration frame, such as shown in FIG. 5a or FIG. 5b. That is, in the perception configuration phase, the perception node 1 performs S302.

[0266] For example, the first frame is a perception configuration frame, such as shown in FIG. 5a or FIG. 5b. That is, in the perception configuration phase, the perception node 1 performs S302.

[0267] For example, the first frame is a perception configuration frame, such as shown in FIG. 5a or FIG. 5b. That is, in the perception configuration phase, the perception node 1 performs S302.

[0268] For example, the first frame is a perception configuration frame, such as shown in FIG. 5a or FIG. 5b. That is, in the perception configuration phase, the perception node 1 performs S302.

[0269] Table 1

[0270] Table 2

[0271] As shown in Table 1 or FIG. 5a, the first frame includes field 1, and field 1 carries the first range information. Field 1 can also have other names, such as a perception target range information field. The present application takes field 1 as an example for introduction.

[0272] As shown in Table 2 or FIG. 5b, the first frame includes field 1 and field 2. Field 1 carries the first range information, which can be referred to the introduction of Table 1 and will not be repeated. Field 2 carries the identification of the first target. Field 2 can also have other names, such as a perception target information field. The present application takes field 2 as an example for introduction.

[0273] Optionally, as shown in Table 1 or Table 2, the first frame further includes one or more of the following fields: field 3, field 4, field 5, field 6, field 7, and field 8.

[0274] Field 3 carries first information, and the first information indicates a perception task type for perceiving the first target, which can be referred to the introduction of S341 and will not be repeated. Field 3 can also have other names, such as a perception task type field. The present application takes field 3 as an example for introduction.

[0275] The field 4 carries an index of the sensing signal configuration. It can be understood that the first range information is associated with the sensing signal configuration, or the first range information is configured by the sensing signal configuration. The field 4 can also be named as a sensing signal configuration index field. The field 4 is taken as an example for description.

[0276] The field 5 carries a parameter of the first signal, such as a transmission parameter of the first signal, or a reception parameter of the first signal. The parameter of the first signal can include at least one of a transmission bandwidth of the first signal, or a frequency range of the first signal. The parameter carried by the field 5 in the first frame can be determined based on the first range information, or can be determined by referring to other factors. The field 5 can also be named as a sensing measurement parameter field. The field 5 is taken as an example for description.

[0277] The field 6 is used to indicate a sensing report feedback type. The sensing report feedback type can be one of sensing measurement data, a range-doppler map, or a position of a sensing target. The sensing measurement data can include CIR or CSI, etc. The field 6 can also be named as a sensing report feedback type field. The field 6 is taken as an example for description.

[0278] The field 7 indicates a sensing role supported by the peer node as a participating device in the sensing process. For example, taking that the sensing node 1 sends the first frame to the sensing node 2 as an example, the field 7 indicates whether the sensing node 2 is a sensing sender or a sensing receiver. The sensing sender is used to send a signal, and the sent signal is used to sense a first target. The sensing receiver is used to receive a signal, and the received signal is used to sense a first target. Please refer to the introduction of FIG. 2a, which will not be described here. The field 7 can also be named as a sensing interaction attribute field. The field 7 is taken as an example for description.

[0279] The field 8 indicates sensing node position information. For example, taking that the sensing node 1 sends the first frame to the sensing node 2 as an example, the field 8 is used to indicate the position of the sensing node 1. The field 8 can also be named as a sensing node position information field. The field 8 is taken as an example for description.

[0280] It is easy to understand that the first frame can also include other fields. Alternatively, the first range information can also be transmitted by other frames in the sensing configuration stage, which is not limited.

[0281] Exemplarily, taking that the first frame is a sensing measurement request frame as an example, the first frame includes a plurality of fields, and each field carries a parameter as shown in FIG. 5c, FIG. 5d or FIG. 5e:

[0282] As shown in FIG. 5c, the first frame includes the following fields: category, public action, dialog token, sensing comeback info, measure session ID indication, and sensing measurement Parameters element.

[0283] The sensing measurement Parameters element field includes the following subfields: element ID, length, element ID Extension, sensing measurement Parameters, and sensing subelements.

[0284] The sensing measurement Parameters subfield includes the following fields:

[0285] sensing transmitter, sensing receiver, sensing measurement report Requested, measurement session expiry exponent, bandwidth (BW), TX HE-LTF repetition, RX HE-LTF repetition, TX STS, RX STS, number of RX antennas, Report timestamp, subcarrier grouping (I Ng ), BSS color Information, and Reserved field.

[0286] For example, in FIG. 5c, the first range information can be carried in the sensing measurement Parameters subfield, such as, after the BSS color Information, before the Reserved field.

[0287] For example, in FIG. 5d and FIG. 5e, the sensing subelements subfield carries different sensing subelements according to different sensing measurement types, including TB Sensing Specific subelement, Non-TB Sensing Specific subelement. Wherein, TB is trigger based, which can be understood as based on trigger. Non-TB can be understood as non-trigger.

[0288] For example, in FIG. 5d, the TB Sensing Specific subelement includes the following fields: subelement ID, length, AID, CSI variation threshold, SR2SR, poll assigned, Reserved, and availability window.

[0289] For example, in FIG. 5d, the first range information can be carried in the TB Sensing Specific subelement subfield, such as, after the poll assigned, before the Reserved field.

[0290] For example, in FIG. 5e, the Non-TB Sensing Specific subelement includes the following fields: subelement ID, length, min measurement interval.

[0291] For example, in FIG. 5d, the first range information can be carried in the Non-TB Sensing Specific subelement subfield, such as, after the min measurement interval.

[0292] It is easy to understand that the first frame can also include other fields. Alternatively, the first range information can also be transmitted through other frames in the perception measurement session establishment stage, without limitation.

[0293] It is easy to understand that when the perception node 1 and the perception node 2 are different perception nodes, the processing process is as introduced in S301-S302. For the perception node 2, it can be understood that the perception node 2 acquires the first range information.

[0294] For the perception node 2, after the perception node 2 acquires the first range information, S303 is performed:

[0295] S303, the perception node 2 performs perception measurement on the first target according to the first range information.

[0296] Exemplarily, S303 includes that the perception node 2 transmits or receives a first signal according to the first range information. The first signal is used for the perception measurement on the first target.

[0297] Taking FIG. 2f as an example, the perception node 2 can be the perception node B in FIG. 2f, and the first target is a human body. After the perception node B receives the first range information, the perception node B performs perception measurement on the human body according to the first range information.

[0298] For example, the perception node 2 is a perception transmitter. Correspondingly, the perception node 2 determines transmission parameters of the first signal according to the first range information, and transmits the first signal according to the transmission parameters of the first signal. The transmission parameters of the first signal include at least one of the following: a transmission bandwidth of the first signal, a frequency range of the first signal, a transmission power of the first signal, a continuous transmission time length of the first signal, a transmission period of the first signal, or a transmission beam angle of the first signal.

[0299] It is pointed out that, in the present application, regarding the transmission bandwidth of the first signal: the greater the transmission bandwidth, the higher the distance resolution. In a scene where the target distribution is relatively sparse, a smaller transmission bandwidth can be used, thereby saving signal transmission resources. In a scene where the target distribution is relatively dense, a larger transmission bandwidth can be used, thereby achieving better recognition effect.

[0300] It is pointed out that, in the present application, regarding the frequency range of the first signal, which can also be referred to as the frequency point of the first signal, it can include one of the following: 2.4G, 5G, 7.9G, or 60G. The lower the frequency point, the stronger the penetration. In a scene where the distribution of obstacles (such as walls) is relatively dense, a lower frequency point can be used, thereby achieving better signal penetration effect. In a scene where the distribution of obstacles is relatively sparse, a higher frequency point can be used.

[0301] It should be noted that in this application, the transmission power of the first signal can also be described as the transmission power of the first signal, or the signal transmission power, etc. In this application, the transmission power of the first signal is taken as an example for introduction.

[0302] It should be noted that in this application, the duration of the continuous transmission of the first signal can also be described as the duration of the first signal.

[0303] It should be noted that in this application, the following cases (cases 1-3) can exist:

[0304] Case 1, the first frame carries the sensing measurement parameter. In this case, the transmission parameter of the first signal determined by the sensing node 2 according to the first range information refers to other parameters in addition to the above-mentioned sensing measurement parameter. For example, if the sensing measurement parameter carried by the first frame includes the transmission bandwidth and frequency range of the first signal, the transmission parameter (i.e. the transmission parameter of the first signal) determined by the sensing node 2 according to the first range information includes at least one of the following: the transmission power of the first signal, the duration of the continuous transmission of the first signal, the transmission period of the first signal, or the transmission beam angle of the first signal, but does not include the transmission bandwidth and frequency range of the first signal. Wherein, the sensing measurement parameter carried by the first frame can refer to the introduction of Table 1 or Table 2, and will not be repeated here.

[0305] Case 2, the first frame carries the sensing measurement parameter, but the sensing node 2 refuses the sensing measurement parameter carried in the first frame, and the sensing node 2 determines the transmission parameter of the first signal according to the first range information. For example, if the sensing measurement parameter carried by the first frame includes the transmission bandwidth and frequency range of the first signal, but the sensing node 2 refuses the parameter (i.e. the sensing measurement parameter carried in the first frame). And the sensing node 2 also determines the transmission parameter of the first signal according to the first range information. Wherein, the transmission parameter (i.e. the transmission parameter of the first signal) determined by the sensing node 2 according to the first range information includes the transmission bandwidth and frequency range of the first signal, and optionally includes at least one of the following: the transmission power of the first signal, the duration of the continuous transmission of the first signal, the transmission period of the first signal, or the transmission beam angle of the first signal.

[0306] Case 3, the first frame does not carry the sensing measurement parameter. In this case, the sensing node 2 determines the transmission parameter of the first signal according to the first range information. Wherein, the transmission parameter of the first signal includes at least one of the following: the transmission bandwidth of the first signal, the frequency range of the first signal, the transmission power of the first signal, the duration of the continuous transmission of the first signal, the transmission period of the first signal, or the transmission beam angle of the first signal, etc.

[0307] For another example, the perception node 2 is a perception receiver. Accordingly, the perception node 2 determines the reception parameter of the first signal according to the first range information, and receives the first signal according to the reception parameter of the first signal. The reception parameter of the first signal includes at least one of the following: a frequency range of the first signal, an automatic gain control (AGC), or a reception beam angle of the first signal.

[0308] It should be noted that in the present application, the following cases (Cases 4-6) can exist:

[0309] Case 4, the first frame carries the perception measurement parameter. In this case, the reception parameter of the first signal determined by the perception node 2 according to the first range information refers to other parameters except the above-mentioned perception measurement parameter. For example, if the perception measurement parameter carried by the first frame includes the bandwidth and the frequency range of the first signal, the reception parameter (i.e., the reception parameter of the first signal) determined by the perception node 2 according to the first range information includes at least one of the following: the AGC, or the reception beam angle of the first signal, but does not include the bandwidth and the frequency range of the first signal. The perception measurement parameter carried by the first frame can refer to the introduction of Table 1 or Table 2, and will not be described again.

[0310] Case 5, the first frame carries the perception measurement parameter, but the perception node 2 refuses the perception measurement parameter carried in the first frame, and the perception node 2 determines the reception parameter of the first signal according to the first range information. For example, if the perception measurement parameter carried by the first frame includes the bandwidth and the frequency range of the first signal, but the perception node 2 refuses the parameter (i.e., the perception measurement parameter carried in the first frame). And the perception node 2 also determines the reception parameter of the first signal according to the first range information. The reception parameter (i.e., the reception parameter of the first signal) determined by the perception node 2 according to the first range information includes the bandwidth and the frequency range of the first signal, and optionally includes at least one of the following: the AGC, or the reception beam angle of the first signal.

[0311] Case 6, the first frame does not carry the perception measurement parameter. In this case, the perception node 2 determines the reception parameter of the first signal according to the first range information. The reception parameter of the first signal includes at least one of the following: the bandwidth of the first signal, the frequency range of the first signal, the AGC, or the reception beam angle of the first signal, etc.

[0312] It is to be noted that, in the present application, for the above case 1-case 6, further, the sensing node 2 also sends a third frame to the sensing node 1. Wherein, the third frame is used to indicate that the first frame is received successfully. Exemplarily, the third frame can be a sensing measurement response frame, or a sensing configuration feedback frame. Optionally, corresponding to case 2 and case 5, the third frame can also indicate rejection, i.e. indicate rejection of the sensing measurement parameter in the first frame. Optionally, the third frame can also indicate a suggested parameter. Wherein, the suggested parameter refers to a parameter suggested to be used when performing sensing measurement on the first target, or a parameter recommended to be used when performing sensing measurement on the first target. The suggested parameter can also have other names, such as recommended parameter.

[0313] Based on the above introduction, the sensing node 2 adjusts the sending parameter and / or receiving parameter of the first signal according to the first range information, and sends or receives the first signal based on the adjusted parameter, so as to sense the first target according to the first signal.

[0314] It is to be noted that, in S303, for the first target sensing process performed by the sensing node 2, the sensing mode can be one of the following: self-sending and self-receiving, receiving and sending separation, or cooperative sensing.

[0315] Wherein, the first target sensing process in the self-sending and self-receiving mode can be performed by the sensing node 2. For example, the sensing node 2 sends the first signal according to the sending parameter of the first signal. After the first signal passes through the first target, the sensing node 2 receives the first signal according to the receiving parameter of the first signal, as shown in FIG. 6.

[0316] Wherein, the first target sensing process in the receiving and sending separation mode can be performed by the sensing node 2 and the sensing node 3. Wherein, the sensing node 3 and the sensing node 2 are both sensing nodes.

[0317] For example, the sensing node 2 is a sensing sender, and the sensing node 3 is a sensing receiver, i.e. the sensing node 2 sends the first signal to the sensing node 3 according to the sending parameter of the first signal. Correspondingly, the sensing node 3 receives the first signal from the sensing node 2, as shown in FIG. 6.

[0318] For another example, the sensing node 3 is a sensing sender, and the sensing node 2 is a sensing receiver, i.e. the sensing node 3 sends the first signal to the sensing node 2. Correspondingly, the sensing node 2 receives the first signal from the sensing node 3 according to the receiving parameter of the first signal, as shown in FIG. 6.

[0319] It is to be noted that, in the present application, whether the sensing node 2 is a sensing sender or a sensing receiver can be determined based on the first frame, which will be described in detail in the introduction of Table 1, and will not be described again.

[0320] It should be noted that in the present application, the perception node 3 can be the perception node 1 described above, and can also be other nodes in addition to the perception node 1 and the perception node 2, and is not limited.

[0321] The first target perception process of the cooperative perception mode can be performed by the perception node 2, that is, cooperative perception is achieved through self-reception or transmission-reception separation, which is described in detail in the foregoing paragraphs and will not be repeated.

[0322] Further, in the first target perception process of the transmission-reception separation or cooperative perception mode, the present application further includes a parameter negotiation process. For example, for the perception node 2, as shown in FIG. 6, the perception node 2 also performs S304a when sending the first signal. Alternatively, the perception node 2 also performs S304b when receiving the first signal. The descriptions of S304a and S304b are as follows:

[0323] S304a, the perception node 2 sends the reception parameter of the first signal to the perception node 3. Correspondingly, the perception node 3 receives the reception parameter of the first signal from the perception node 1.

[0324] The reception parameter of the first signal is determined by the perception node 2 according to the first range information.

[0325] For the perception node 3, the perception node 3 receives the first signal from the perception node 2, including: the perception node 3 receives the first signal from the perception node 2 according to the reception parameter of the first signal.

[0326] For example, taking FIG. 2f as an example, the perception node 2 can be the perception node B in FIG. 2f, the perception node 3 can be the perception node C in FIG. 2f, and the first target is a human body. In the case that the perception node B and the perception node C perform perception measurement on the human body through the transmission-reception separation or cooperative perception mode, the perception node B sends the reception parameter of the first signal to the perception node C, so that the perception node C receives the first signal according to the reception parameter, and achieves the perception measurement on the human body.

[0327] S304b, the perception node 2 sends the transmission parameter of the first signal to the perception node 3. Correspondingly, the perception node 3 receives the transmission parameter of the first signal from the perception node 1.

[0328] The transmission parameter of the first signal is determined by the perception node 2 according to the first range information.

[0329] For the perception node 3, the perception node 3 sends the first signal to the perception node 2, including: the perception node 3 sends the first signal to the perception node 2 according to the transmission parameter of the first signal.

[0330] For example, in FIG. 2f, the sensing node 2 can be the sensing node B in FIG. 2f, and the sensing node 3 can be the sensing node C in FIG. 2f. The first target is a human body. In the case where the sensing node B and the sensing node C perform sensing measurement on the human body through the transceiving separation or cooperative sensing mode, the sensing node B sends the sending parameter of the first signal to the sensing node C, so that the sensing node C sends the first signal according to the sending parameter, and the sensing measurement on the human body is realized.

[0331] It should be noted that in the present application, the first signal can be described as a first communication signal, a first sensing signal, or a first measurement signal, etc. For details, please refer to the introduction in the glossary section, which will not be repeated here.

[0332] It is easy to understand that in the present application, S303 can be understood as a precise measurement stage. That is, based on the range where the first target is located, the position of the first target is obtained, so that the target is precisely sensed.

[0333] That is, the rough range where the first target is located, i.e. the first range information, is obtained first, and then the first target is precisely sensed based on the first range information, so that the sensing result of the first target is obtained. In the present application, since the sensing of the first target based on the first range information, such as the adjustment of the first signal based on the first range information, the coverage range of the first signal is small. Compared with the sensing of the first target without obtaining the first range information, the present application can reduce the invalid range coverage of the signal and the interference of the invalid range reflection signal, thereby improving the sensing precision and enhancing the sensing performance.

[0334] For example, the processing mode of sensing the first target without obtaining the first range information is as follows:

[0335] Mode 1: The detection device sends a first detection signal, and the signal transmission device sends a second detection signal based on the first detection signal. The detection area of the second detection signal covers the detection blind area of the first detection signal. The second detection signal is the transmission signal of the first detection signal after the signal transmission device. Moreover, the signal transmission device receives a first echo signal of the second detection signal and sends a second echo signal to the detection device based on the first echo signal. The detection device detects the target in the first detection blind area based on the second echo signal. That is, based on the second echo signal, the target in the detection blind area can be detected, including the distance, speed, direction angle and radar cross section of the target. Combined with the distance between the detection device and the signal transmission device and the distance between the detection target and the detection device, the distance between the detection target and the signal transmission device can be obtained.

[0336] In the manner 1, the detection blind area of the first detection signal is supplemented by the second detection signal to realize the blind area compensation of the detection blind area, thereby improving the sensing performance of the detection device under the non-line-of-sight condition. However, the manner 1 only relates to the detection range and the blind area of the detection device, the blind area is related to the range that can be detected by the detection device itself, and other devices are used to expand the coverage range, but does not relate to the range where the first target is located (i.e., the above-mentioned first range information). In the sensing application scenario, the range where the first target is located (i.e., the above-mentioned first range information) can be a relatively small range, and the detection device does not need to further expand the coverage range, as long as the first target can be accurately sensed. If the detection range is simply expanded without adjusting the signal transmission parameter according to the first range information, the detection signal resource can be wasted, and other interference in the space can also be included, which affects the sensing accuracy.

[0337] In the manner 2, the first signal and the second signal are respectively received according to the first transmission parameter set and the second transmission parameter set, and the sensing result is obtained according to the first signal and the second signal. The first transmission parameter set corresponds to the first signal, and at least one parameter in the first transmission parameter set satisfies the first condition, the first condition is related to the target ranging range, the second transmission parameter set corresponds to the second signal, and at least one parameter in the second transmission parameter set satisfies the second condition, the second condition is related to the target sensing accuracy, so that the sensing result based on the sensing of the first signal and the second signal can meet the sensing demand, and the signal transmission resource is flexibly allocated according to the sensing demand.

[0338] In the manner 2, the first result is obtained according to the first signal, the second result is obtained according to the second signal, and the sensing result is determined according to the first result and the second result. The first signal satisfies the target ranging range, and the second signal satisfies the target ranging accuracy. Based on the first result, the measurement value closest to the actual value is selected from the multiple measurement values of the second result as the sensing result, so as to improve the ranging accuracy while ensuring that the ranging is not ambiguous. In the manner 2, the problem of large invalid coverage range of the signal and the interference of the invalid coverage range reflection signal still exists.

[0339] In the present application, the first range information is obtained first, and then the first target is sensed based on the first range information. Compared with the way of sensing the first target without obtaining the first range information, the present application can reduce the signal resource consumption, reduce the invalid range coverage of the signal and the interference of the invalid range reflection signal, thereby improving the sensing accuracy and efficiency.

[0340] It should be pointed out that the present application can reduce the invalid range coverage of the signal and the interference of the invalid range reflection signal, and the specific analysis and examples are as follows:

[0341] For example, when the perception node 2 performs human sleep monitoring, the signal coverage range of the perception node 2 may reach the entire room without using the technical solution of the present application, but the effective perception data comes from the reflection signal of the position where the human body is located. At this time, the reflection signal in other ranges is not only invalid signal, but also may bring interference, which is difficult to distinguish from the human target when the algorithm is processed. In the present application, the perception node 2 can obtain the first range information, such as the position range of the human body lying on the bed to sleep, so as to reduce the perception coverage range and optimize and adjust the perception parameters for the area where the human body is located. Then, the signal is received and transmitted based on the optimized and adjusted parameters, so as to improve the monitoring pertinence and avoid the interference of the signal in other ranges. In addition, when the perception node 2 feeds back the first perception result, the signal corresponding to the human body can be locked for feedback, so as to save the amount of perception report feedback.

[0342] It should be noted that if the first range information is determined based on the relative coordinate system. As shown in FIG. 7, the perception node 1 also provides the position of the first reference point to the perception node 2, that is, the present application also includes S311:

[0343] S311, the perception node 1 sends the position information of the first reference point to the perception node 2. Correspondingly, the perception node 2 receives the position information of the first reference point from the perception node 1.

[0344] The position information of the first reference point is determined based on the absolute coordinate system. For example, the position information of the first reference point includes the longitude and latitude of the first reference point.

[0345] For example, the first range information indicates the position of the human body, such as being located 0.2 meters in front of the perception node A. That is, the position information of the first reference point is the position of the perception node A. The perception node A sends its own position information to the perception node B, so that the perception node B determines the human body position range based on the position of the perception node A.

[0346] Optionally, the position information of the first reference point is carried in the first frame, such as a perception measurement request frame or a perception configuration frame.

[0347] In the case where S311 is performed, for the perception node 2, S303 includes: the perception node 2 performs perception measurement on the first target according to the first range information and the position of the first reference point, so as to adapt to the current perception range.

[0348] Exemplarily, the perception node 2 determines the range between itself and the first target according to the position of the first reference point and the first range information, and then determines the transmission parameter or the reception parameter of the first signal according to the range between itself and the first target.

[0349] For example, in the case that the distance between the first target and the perception node 2 is short, the perception node 2 determines the transmission parameter or the reception parameter of the first signal. For example, in the transmission parameter of the first signal, the transmission power of the first signal is small, and in the reception parameter of the first signal, the AGC of the first signal is small, so as to prevent the receiver from being saturated.

[0350] For another example, in the case that the distance between the first target and the perception node 2 is long, the perception node 2 determines the transmission parameter or the reception parameter of the first signal. For example, in the transmission parameter of the first signal, the transmission power of the first signal is large, and in the reception parameter of the first signal, the AGC of the first signal is large, so as to improve the signal-to-noise ratio of the signal.

[0351] It is easy to understand that in the present application, S311 is an optional step. The perception node 1 can perform S311 or not perform S311. For example, if the first range information is determined based on the relative coordinate system or the perception node 1 is pre-configured with the position information of the first reference point, the perception node 1 can perform S311. For another example, if the first range information is determined based on the absolute coordinate system or the perception node 2 is pre-configured with the position information of the first reference point or the position information of the first reference point is pre-defined by the protocol, the perception node 1 can not perform S311.

[0352] Further, when the perception node 1 performs S311, the perception node 1 can perform S302 first and then perform S311, or perform S311 first and then perform S302, or perform S302 and S311 at the same time, which is not limited.

[0353] It is necessary to supplement that if the first target is a moving target, as shown in FIG. 7, the perception node 1 further provides the moving speed information of the first target to the perception node 2, that is, the present application further includes S321:

[0354] S321, the perception node 1 sends the moving speed information of the first target to the perception node 2. Correspondingly, the perception node 2 receives the moving speed information of the first target from the perception node 1.

[0355] For example, the moving speed information of the first target can be understood as the moving speed of the first target relative to the first reference point.

[0356] For example, as shown in FIG. 2f, the sensing node 1 can be the sensing node A in FIG. 2f, and the sensing node 2 can be the sensing node B in FIG. 2f. The first target can be a human body. For example, at time 1, the human body is located near the door of the room, the sensing node A performs sensing measurement on the human body, and obtains the first range information and the moving speed information of the first target. The first range information indicates the position of the human body, such as 0.2 meters in front of the door of the room. The moving speed information of the first target indicates the moving speed of the human body. In this case, the sensing node A sends the first range information and the moving speed information of the first target to the sensing node B, so that the sensing node B performs sensing on the human body based on the first range information and the moving speed information of the first target.

[0357] Optionally, the moving speed of the first target is carried in the first frame, such as a sensing measurement request frame or a sensing configuration frame.

[0358] In the case where S321 is performed, for the sensing node 2, S303 includes: the sensing node 2 performs sensing measurement on the first target according to the first range information and the moving speed information of the first target, so as to achieve continuous monitoring.

[0359] For example, in the case where the moving speed of the first target is large, the sensing node 2 determines the sending parameters of the first signal according to the first range information and the moving speed information of the first target. The sending period of the first signal is small, so as to prevent the target from being lost.

[0360] For another example, in the case where the moving speed of the first target is small, the sensing node 2 determines the sending parameters of the first signal according to the first range information and the moving speed information of the first target. The sending period of the first signal is large, so as to save signal resources.

[0361] It is easy to understand that, in the present application, S321 is an optional step. The sensing node 1 can perform S321, or can not perform S321. For example, if the first target is a moving target, the sensing node 1 can perform S321. For another example, if the first target is a stationary target, the sensing node 1 can not perform S321. In the present application, the stationary target can be understood as that the position of the first target does not change, or the position of the first target changes little, such as below a certain threshold. For example, the first target is a human body. For example, in the sleep state, the human body can be considered as not changing position.

[0362] Further, when the sensing node 1 performs S321, S302 can be performed first, or S321 can be performed first, or S302 and S321 can be performed simultaneously, which is not limited.

[0363] In some embodiments, as shown in FIG. 7, the sensing node 1 further provides the first confidence information to the sensing node 2, i.e., the present application further comprises S331:

[0364] S331, the sensing node 1 sends the first confidence information to the sensing node 2. Correspondingly, the sensing node 2 receives the first confidence information from the sensing node 1.

[0365] The first confidence information indicates a probability that the range where the first target is located is the first range information. That is, the higher the value of the first confidence information, the greater the probability that the range where the first target is located is the first range information. The lower the value of the first confidence information, the smaller the probability that the range where the first target is located is the first range information. For example, the first confidence information is 0.8.

[0366] Optionally, the first confidence information is carried in the first frame, such as a sensing measurement request frame or a sensing configuration frame.

[0367] In the case where S331 is performed, for the sensing node 2, S303 comprises: the sensing node 2 performs sensing measurement on the first target according to the first range information and the first confidence information, so as to improve the target sensing efficiency.

[0368] For example, the sensing node 2 determines the transmission parameter or the reception parameter of the first signal according to the first confidence information and the first range information.

[0369] For example, in the case where the first confidence is greater than a first threshold, the sensing node 2 determines the transmission parameter or the reception parameter of the first signal, so as to improve the target sensing efficiency. Conversely, in the case where the first confidence is less than or equal to the first threshold, the sensing node 2 does not need to determine the transmission parameter or the reception parameter of the first signal, does not perform the sensing process of the first target, and reduces unnecessary signal resource overhead. The first threshold can be 0.6, 0.6 or 0.75, etc. The first threshold can be determined according to historical experience value, which is not limited.

[0370] It is easy to understand that in the present application, S331 is an optional step. The sensing node 1 can perform S331 or not perform S331. For example, if the current data transmission amount is small and the communication resource is relatively idle, the sensing node 1 can perform S331. For another example, if the current data transmission amount is large and the communication resource is relatively tight, the sensing node 1 can not perform S331.

[0371] Further, when the sensing node 1 performs S331, S302 can be performed first, or S331 can be performed first, or S302 and S331 can be performed simultaneously, which is not limited.

[0372] In some embodiments, as shown in FIG. 7, the sensing node 1 also provides the sensing task type to the sensing node 2, i.e., the present application also includes S341:

[0373] S341, the sensing node 1 sends the first information to the sensing node 2. Correspondingly, the sensing node 2 receives the first information from the sensing node 1.

[0374] The first information indicates the sensing task type of sensing the first target.

[0375] Exemplarily, the sensing task type includes a first task type and a second task type.

[0376] The first task type can include fall detection, large motion recognition, and other large disturbance tasks. In the present application, the first task type is exemplified by the human body movement in FIG. 2f.

[0377] The second task type can include breathing and heartbeat monitoring, weak signal detection, and other small disturbance tasks. In the present application, the second task type is exemplified by the breathing and heartbeat monitoring when the human body is sleeping in FIG. 2b or FIG. 2c.

[0378] Optionally, the first information is carried in a first frame. As shown in Table 1 or Table 2, the first frame also includes a field 3, and the field 3 carries the first information. The field 3 can have other names, such as a sensing task type field.

[0379] In the case where S341 is performed, for the sensing node 2, S303 includes: the sensing node 2 performs sensing measurement on the first target according to the first range information and the sensing task type, to adapt to the current sensing task and the sensing range.

[0380] For example, in the case where the sensing task type is the first task type, the sensing node 2 determines the transmission parameter or the reception parameter of the first signal. In the transmission parameter of the first signal, the transmission power of the first signal is small, and in the reception parameter of the first signal, the AGC of the first signal is small, to prevent the receiver from being saturated.

[0381] For another example, in the case where the sensing task type is the second task type, the sensing node 2 determines the transmission parameter or the reception parameter of the first signal. In the transmission parameter of the first signal, the transmission power of the first signal is large, and in the reception parameter of the first signal, the AGC of the first signal is large, to improve the signal-to-noise ratio of the signal.

[0382] It is easy to understand that in this application, S341 is an optional step. The perception node 1 can perform S341 or not perform S341. For example, in the case that the perception node 1 is pre-configured with the perception task type, the perception node 1 can perform S341. For another example, in the case that the perception node 2 is pre-configured with the perception task type, or the protocol is pre-defined with the perception task type, the perception node 1 can not perform S341.

[0383] Further, when the perception node 1 performs S341, the perception node 1 can perform S302 first and then perform S341, or perform S341 first and then perform S302, or perform S302 and S341 at the same time, which is not limited.

[0384] In some embodiments, as shown in FIG. 8, the perception node 2 further performs a perception result reporting process, that is, the present application further includes S351:

[0385] S351, the perception node 2 sends the first perception result to the perception center 1. Correspondingly, the perception center 1 receives the first perception result from the perception node 2.

[0386] Wherein, the perception center 1 can refer to the introduction of the perception center in FIG. 1, which will not be repeated.

[0387] Wherein, the first perception result is determined according to the first signal. For example, the first perception result is determined by the perception node 2 according to the perception process of the first signal.

[0388] Wherein, the first perception result indicates the position of the first target. Illustratively, the first perception result is based on the position information of the first reference point, and it can be understood that the first perception result indicates the position of the first target relative to the first reference point. For example, the first perception result indicates that the distance between the first target and the first reference point is 5 meters, the azimuth angle between the first target and the first reference point is 30°, and the pitch angle between the first target and the first reference point is 0°.

[0389] Taking FIG. 2f as an example, the perception node 2 can be the perception node B in FIG. 2f, the perception center 1 can be the perception center in FIG. 2f, and the first target is a human body. For example, at time 2, the human body is located in the living room, such as being located 0.2 meters in front of the perception node A, the perception node B performs perception measurement on the human body and obtains the first perception result. Wherein, the first perception result indicates the position of the human body. The perception node B sends the first perception result to the perception center of the living room.

[0390] Optionally, the first perception result is carried in a second frame. Wherein, the second frame is used for reporting the perception result. For example, the second frame is a perception result reporting frame, or the second frame is a perception information reporting frame.

[0391] Exemplarily, the second frame includes one or more fields, and each field carries parameters as shown in Table 3:

[0392] Table 3

[0393] As shown in Table 3, the second frame includes a target feedback field, and the target feedback field carries the first sensing result. The first sensing result can be understood in the foregoing paragraphs, and will not be described herein.

[0394] Optionally, as shown in Table 3, the second frame further includes one or more of the following fields: a sensing signal configuration index field, or a sensing signal parameter field.

[0395] The sensing signal configuration index field is used to indicate the index of the sensing signal configuration, which can be understood in Table 1 or Table 2, and will not be described herein.

[0396] The sensing signal parameter field is used to indicate the parameter of the first signal, which can be understood as the parameter actually used when the first target is measured. The parameter indicated by the sensing signal parameter field can include at least one of the following: the transmission bandwidth of the first signal, the frequency range of the first signal, or the transmission period of the first signal, etc.

[0397] It is easy to understand that the second frame can also include other fields, which are not limited.

[0398] It should be added that in the present application, the target feedback field can also be replaced by a CSI feedback field. The CSI feedback field carries CSI data, and the CSI data is used to determine the first sensing result. That is, the sensing node 2 performs sensing measurement to obtain CSI data, and reports the CSI data through the CSI feedback field in the second frame, so that the sensing center 1 determines the first sensing result based on the CSI data.

[0399] That is, if the first target sensing process is in the cooperative sensing mode, the sensing node 2 can also report the first sensing result to the sensing center 1, so that the sensing center 1 performs data association or fusion processing on different sensing results, thereby improving the sensing accuracy and efficiency.

[0400] The above is described by taking the sensing node 2 adjusting the signal transmission and reception parameters according to the first range information as an example.

[0401] The following is described by taking the sensing center adjusting the signal transmission and reception parameters according to the first range information as an example:

[0402] As shown in FIG. 9, the wireless sensing method 900 of the present application includes the following operations:

[0403] S901, the sensing node 4 determines the first range information.

[0404] The perception node 4 can refer to the introduction of the perception node in FIG. 1, and will not be repeated here.

[0405] The first range information indicates a range where the first target exists. S901 can refer to the introduction of S301, and will not be repeated here.

[0406] S902, the perception node 4 sends the first range information to the perception center 2. Correspondingly, the perception center 2 receives the first range information from the perception node 4.

[0407] The perception center 2 can refer to the introduction of the perception center in FIG. 1, and will not be repeated here.

[0408] Taking FIG. 2f as an example, the perception node 4 can be the perception node A in FIG. 2f, the perception center 2 can be the perception center in FIG. 2f, and the first target is a human body. For example, at time 2, the perception node A sends the first range information to the perception center. The perception center receives the first range information from the perception node A. The first range information indicates the position of the human body, such as being located in the living room or being located 0.2 meters in front of the perception node A.

[0409] Optionally, in the perception measurement session establishment phase, the perception node 4 performs S902. Exemplarily, the first range information is carried in a first frame, such as a perception measurement request frame.

[0410] Optionally, in the perception configuration phase, the perception node 4 performs S902. Exemplarily, the first range information is carried in a first frame, such as a perception configuration frame.

[0411] S902 can refer to the introduction of S302, and will not be repeated here.

[0412] For the perception center 2, after receiving the first range information, the perception center 2 performs S903:

[0413] S903, the perception center 2 determines a second parameter according to the first range information.

[0414] The second parameter includes a transmission parameter and / or a reception parameter of the first signal, which can refer to the introduction of S303, and will not be repeated here.

[0415] For example, the perception center 2 determines the range between the perception node 5 and the first target according to the first range information, and then determines the transmission parameter of the first signal according to the range between the perception node 5 and the first target. The transmission parameter of the first signal includes at least one of the following: a transmission bandwidth of the first signal, a frequency range of the first signal, a transmission power of the first signal, a continuous transmission time length of the first signal, a transmission period of the first signal, or a transmission beam angle of the first signal.

[0416] For example, the sensing node 5 can be the sensing node B in FIG. 2f, and the sensing center 2 can be the sensing center in FIG. 2f. For example, at time 2, the sensing center determines the receiving parameter of the first signal according to the first range information.

[0417] For example, the sensing center 2 determines the range between the sensing node 5 and the first target according to the first range information, and determines the receiving parameter of the first signal according to the range between the sensing node 5 and the first target. The receiving parameter of the first signal includes at least one of the following: AGC, or the receiving beam angle of the first signal.

[0418] For example, the sensing node 5 can be the sensing node B in FIG. 2f, and the sensing center 2 can be the sensing center in FIG. 2f. For example, at time 2, the sensing center determines the receiving parameter of the first signal according to the first range information.

[0419] For the sensing center 2, after the sensing center 2 determines the second parameter, the sensing center 2 performs S904:

[0420] S904: The sensing center 2 sends the second parameter to the sensing node 5. Correspondingly, the sensing node 5 receives the second parameter from the sensing center 2.

[0421] For example, the sensing node 5 can be the sensing node B in FIG. 2f, and the sensing center 2 can be the sensing center in FIG. 2f. For example, the sensing center in the living room sends the second parameter to the sensing node B.

[0422] Optionally, the sensing center 2 performs S904 in the sensing measurement session establishment stage. Exemplarily, the second parameter is carried in the first frame, such as the sensing measurement request frame.

[0423] Optionally, the sensing center 2 performs S904 in the sensing configuration stage. Exemplarily, the second parameter is carried in the first frame, such as the sensing configuration frame.

[0424] For the sensing node 5, after the sensing node 5 receives the second parameter, the sensing node 5 performs S905:

[0425] S905: The sensing node 5 performs sensing measurement on the first target according to the second parameter.

[0426] Exemplarily, the sensing node 5 sends or receives the first signal according to the second parameter.

[0427] For example, the second parameter includes the sending parameter of the first signal. S905 includes: the sensing node 5 sends the first signal according to the sending parameter of the first signal.

[0428] For example, the sensing node 5 can be the sensing node B in FIG. 2f, and the first target is a human body. For example, the sensing node B sends the first signal to the position near the human body according to the second parameter to perform the sensing measurement on the human body.

[0429] For example, the second parameter includes a receiving parameter of the first signal. The S905 includes: receiving, by the sensing node 5, the first signal according to the receiving parameter of the first signal.

[0430] For example, the sensing node 5 can be the sensing node B in FIG. 2f, and the first target is a human body. For example, the sensing node B receives the first signal reflected near the position of the human body according to the second parameter to perform the sensing measurement on the human body.

[0431] The first signal is used for sensing the first target.

[0432] The S905 can refer to the introduction of the S303, and details are not repeated.

[0433] That is, the sensing center 2 first acquires the rough range of the first target, that is, the first range information, and then determines the second parameter based on the first range information and provides the second parameter to the sensing node 5, so that the sensing node 5 performs accurate sensing on the first target based on the second parameter, thereby obtaining the sensing result of the first target, which helps to reduce the operation amount of the sensing node 5. In this application, since the sensing on the first target is based on the first range information, the coverage range of the first signal is small. Compared with the sensing on the first target without acquiring the first range information, the application can reduce the invalid range coverage of the signal and the interference of the invalid range reflected signal, thereby improving the sensing accuracy and improving the sensing performance.

[0434] It should be noted that if the first range information is determined based on the relative coordinate system. As shown in FIG. 10, the sensing node 4 also provides the position information of the first reference point to the sensing center 2, that is, the application also includes S911:

[0435] The S911 includes: sending, by the sensing node 4, the position information of the first reference point to the sensing center 2. Correspondingly, the sensing center 2 receives the position information of the first reference point from the sensing node 4.

[0436] The position information of the first reference point is determined based on the absolute coordinate system. For example, the position information of the first reference point includes the longitude and latitude of the first reference point.

[0437] For example, as shown in FIG. 2f, the perception node 4 can be the perception node A in FIG. 2f, and the perception center 2 can be the perception center in FIG. 2f. The first target can be a human body. For example, the first range information indicates the position of the human body, such as 0.2 meters in front of the perception node A. That is, the position information of the first reference point is the position of the perception node A. The perception node A sends its position information to the perception center of the living room, so that the perception center determines the range of the human body position based on the position of the perception node A.

[0438] Optionally, the position information of the first reference point is carried in the first frame, such as a perception measurement request frame or a perception configuration frame.

[0439] In the case where S911 is performed, for the perception center 2, S903 includes: determining, by the perception center 2, the second parameter according to the first range information and the position information of the first reference point, to adapt to the current perception range.

[0440] For example, the perception center 2 determines the range between the perception node 5 and the first target according to the position information of the first reference point and the first range information, and determines the transmission parameter or the reception parameter of the first signal according to the range between the perception node 5 and the first target.

[0441] It is easy to understand that in the present application, S911 is an optional step. The perception node 4 can perform S911 or not perform S911. For example, if the first range information is determined based on a relative coordinate system, or the perception node 4 pre-configures the position information of the first reference point, the perception node 4 can perform S911. For another example, if the first range information is determined based on an absolute coordinate system, or the perception center 2 pre-configures the position information of the first reference point, or the protocol pre-defines the position information of the first reference point, the perception node 4 can not perform S911.

[0442] Further, when the perception node 4 performs S911, the perception node 4 can first perform S902 and then perform S911, or first perform S911 and then perform S902, or simultaneously perform S902 and S911, without limitation.

[0443] It should be noted that if the first target is a moving target, as shown in FIG. 10, the perception node 4 further provides the moving speed information of the first target to the perception center 2, that is, the present application further includes S921:

[0444] S921, the perception node 4 sends the moving speed information of the first target to the perception center 2. Correspondingly, the perception center 2 receives the moving speed information of the first target from the perception node 4.

[0445] For example, the moving speed information of the first target can be understood as the moving speed of the first target relative to the first reference point.

[0446] For example, in FIG. 2f, the perception node 4 can be the perception node A in FIG. 2f, and the perception center 2 can be the perception center in FIG. 2f. The first target can be a human body. For example, at time 1, the human body is located near the door of the room, the perception node A performs the perception measurement on the human body, and obtains the first range information and the moving speed information of the first target. The first range information indicates the position of the human body, such as 0.2 meters in front of the door of the room. The moving speed information of the first target indicates the moving speed of the human body. In this case, the perception node A sends the first range information and the moving speed information of the first target to the perception center in the living room, so that the perception center obtains the first range information and the moving speed information of the first target.

[0447] Optionally, the moving speed information of the first target is carried in the first frame, such as the perception measurement request frame or the perception configuration frame.

[0448] In the case where S921 is performed, for the perception center 2, S903 includes: determining, by the perception center 2, the second parameter according to the first range information and the moving speed information of the first target, so as to realize the continuous monitoring.

[0449] For example, the perception center 2 determines the sending parameter or the receiving parameter of the first signal according to the moving speed information of the first target and the first range information.

[0450] It is easy to understand that in the present application, S921 is an optional step. The perception node 4 can perform S921 or can not perform S921. For example, if the first target is a moving target, the perception node 4 can perform S921. For another example, if the first target is a stationary target, the perception node 4 can not perform S921.

[0451] Further, when the perception node 4 performs S921, S921 can be performed first and then S902 can be performed, or S921 can be performed first and then S902 can be performed, or S902 and S921 can be performed at the same time, which is not limited.

[0452] In some embodiments, as shown in FIG. 10, the perception node 4 also provides the first confidence information to the perception center 2, that is, the present application also includes S931:

[0453] S931, the perception node 4 sends the first confidence information to the perception center 2. Correspondingly, the perception center 2 receives the first confidence information from the perception node 4.

[0454] The first confidence information indicates a probability that the range where the first target is located is the first range information. That is, the higher the value of the first confidence information, the greater the probability that the range where the first target is located is the first range information. The lower the value of the first confidence information, the smaller the probability that the range where the first target is located is the first range information. For example, the first confidence information is 0.8.

[0455] Optionally, the first confidence information is carried in the first frame, such as a perception measurement request frame or a perception configuration frame.

[0456] In the case where S931 is performed, for the perception center 2, S903 includes: the perception center 2 determines the second parameter according to the first range information and the first confidence information, to improve the target perception efficiency.

[0457] For example, in the case where the first confidence information is greater than a first threshold, the perception center 2 determines the transmission parameter or the reception parameter of the first signal, so as to improve the target perception efficiency. Conversely, in the case where the first confidence information is less than or equal to the first threshold, the perception center 2 does not need to determine the transmission parameter or the reception parameter of the first signal, does not perform the perception process of the first target, and reduces unnecessary signal resource overhead. The first threshold can be 0.6, 0.6, or 0.75, etc. The first threshold can be determined according to historical experience value, and is not limited.

[0458] It is easy to understand that in the present application, S931 is an optional step. The perception node 4 can perform S931, or can not perform S931. For example, if the current data transmission amount is small and the communication resource is relatively idle, the perception node 4 can perform S931. For another example, if the current data transmission amount is large and the communication resource is relatively nervous, the perception node 4 can not perform S931.

[0459] Further, when the perception node 4 performs S931, S902 can be performed first, or S931 can be performed first, or S902 and S931 can be performed simultaneously, and is not limited.

[0460] In some embodiments, as shown in FIG. 10, the perception node 4 also provides the perception task type to the perception center 2, that is, the present application also includes S941:

[0461] S941, the perception node 4 sends the first information to the perception center 2. Correspondingly, the perception center 2 receives the first information from the perception node 4.

[0462] The first information indicates the perception task type of the perception on the first target, which can be referred to the introduction of S341, and will not be repeated here.

[0463] Optionally, the first information is carried in a first frame, such as a perception measurement request frame or a perception configuration frame.

[0464] In the case where S941 is performed, for the perception center 2, S903 comprises: the perception center 2 determines the second parameter according to the first range information and the perception task type, to adapt the current perception task and the perception range.

[0465] For example, in the case where the perception task type is a first task type, the perception center 2 determines the transmission parameter or the reception parameter of the first signal. In the transmission parameter of the first signal, the transmission power of the first signal is small, and in the reception parameter of the first signal, the AGC of the first signal is small, to prevent the receiver from being saturated.

[0466] For another example, in the case where the perception task type is a second task type, the perception center 2 determines the transmission parameter or the reception parameter of the first signal. In the transmission parameter of the first signal, the transmission power of the first signal is large, and in the reception parameter of the first signal, the AGC of the first signal is large, to improve the signal-to-noise ratio of the signal.

[0467] It is easy to understand that in the present application, S941 is an optional step. The perception node 4 can perform S941, or can not perform S941. For example, in the case where the perception node 4 pre-configures the perception task type, the perception node 4 can perform S941. For another example, in the case where the perception center 2 pre-configures the perception task type, or the protocol pre-defines the perception task type, the perception node 4 can not perform S941.

[0468] Further, when the perception node 4 performs S941, it can first perform S902, and then perform S941, or first perform S941, and then perform S902, or simultaneously perform S902 and S941, without limitation.

[0469] In some embodiments, the perception node 5 also performs the perception result reporting process, as introduced in S351, which will not be described herein.

[0470] The above is introduced taking the perception center 2 adjusting the transmission and reception parameters of the signal according to the first range information as an example.

[0471] The present application provides another wireless perception method. The method can be applied to the system shown in FIG. 1, etc. Next, the wireless perception method proposed by the embodiments of the present application will be introduced in detail in combination with FIG. 11a. The wireless perception method 1100 proposed by the embodiments of the present application comprises the following operations:

[0472] S1101, the perception node 7 acquires the second perception result.

[0473] The perception node 7 can refer to the introduction of the perception node in FIG. 1, and will not be repeated here.

[0474] The second range information indicates a range including the range indicated by the first range information, and the first range information indicates a range where the first target exists. Therefore, the second perception result includes the perception result of the first target.

[0475] For example, the first range information is denoted as [20, 25], and the second range information is denoted as [10, 35]. The second perception result can be CIR data corresponding to [10, 35], or a range-doppler graph corresponding to [10, 35].

[0476] For example, the perception node 7 can be the perception node B in FIG. 2f, and the second range information can be the entire living room in FIG. 2f. The second perception result indicates the perception result of the entire living room.

[0477] For example, as shown in FIG. 11b, S1101 includes S11011-S11013:

[0478] S11011, the perception node 6 determines a first parameter.

[0479] The perception node 6 can refer to the introduction of the perception node in FIG. 1, and will not be repeated here.

[0480] The first parameter includes a transmission parameter or a reception parameter of the second signal.

[0481] For example, the transmission parameter of the second signal includes at least one of the following: a transmission bandwidth of the second signal, a frequency range of the second signal, a transmission power of the second signal, a continuous transmission duration of the second signal, a transmission period of the second signal, or a transmission beam angle of the second signal.

[0482] For example, the reception parameter of the second signal includes at least one of the following: AGC or a reception beam angle of the second signal.

[0483] The coverage range of the second signal can be denoted as a second range, and the second range includes the range indicated by the first range information. The first range information can refer to the introduction of the wireless perception method 300, and will not be repeated here. For example, the first range information is denoted as [20, 25], which can be understood as a distance range of 20 meters to 25 meters from the first reference point. The second range information is denoted as [10, 35], which can be understood as a distance range of 10 meters to 35 meters from the first reference point.

[0484] For the perception node 6, after the perception node 6 determines the first parameter, S11012 is performed:

[0485] S11012, the sensing node 6 sends the first parameter to the sensing node 7. Correspondingly, the sensing node 7 receives the first parameter from the sensing node 6.

[0486] Taking FIG. 2f as an example, the sensing node 6 can be the sensing node A in FIG. 2f, and the sensing node 7 can be the sensing node B in FIG. 2f. In the case that the sensing node A and the sensing node B perform sensing measurement through the transceiving separation or cooperative sensing mode, the sensing node A can determine and provide the first parameter to the sensing node B, so that the sensing node A and the sensing node B jointly perform sensing measurement.

[0487] Optionally, the sensing node 6 performs S11012 in the sensing measurement session establishment phase. For example, the first parameter is carried in the first frame, such as the sensing measurement request frame.

[0488] Optionally, the sensing node 6 performs S11012 in the sensing configuration phase. For example, the first parameter is carried in the first frame, such as the sensing configuration frame.

[0489] For the sensing node 7, after receiving the first parameter, the sensing node 7 performs S11013:

[0490] S11013, the sensing node 7 performs sensing measurement according to the first parameter, and obtains a second sensing result.

[0491] Exemplarily, the first parameter includes the transmission parameter of the second signal, and S11013 includes: the sensing node 7 transmits the second signal according to the transmission parameter of the second signal, and obtains the second sensing result according to the second signal.

[0492] Or, the first parameter includes the reception parameter of the second signal, and S11013 includes: the sensing node 7 receives the second signal according to the reception parameter of the second signal, and obtains the second sensing result according to the second signal.

[0493] It should be noted that, based on S1101, the sensing node 7 obtains the second sensing result. That is, the sensing node 7 can perform sensing measurement on a relatively large range (such as the second range information), so as to obtain the second sensing result. Of course, the sensing node 7 can also obtain the second sensing result through other manners, which is not limited by the present application.

[0494] The above introduces the obtaining process of the second sensing result.

[0495] The following introduces the third sensing result in combination with S1102-S1105:

[0496] S1102, the sensing node 6 determines first range information.

[0497] S1103. The sensing node 6 sends the first range information to the sensing node 7. Correspondingly, the sensing node 7 receives the first range information from the sensing node 6.

[0498] S11012-S1103 can refer to the description of S301-S302, and will not be repeated here.

[0499] S1104. The sensing node 7 selects a third sensing result from the second sensing result according to the first range information.

[0500] The third sensing result indicates the sensing result corresponding to the first range information, and the sensing result of the first range information includes the sensing result of the first target.

[0501] For example, the sensing node 7 selects a third sensing result from the second sensing result according to the first range information.

[0502] For example, the sensing node 7 selects a third sensing result from the second sensing result according to the first range information.

[0503] For the sensing node 7, after obtaining the third sensing result, the sensing node 7 performs S1105:

[0504] S1105. The sensing node 7 sends the third sensing result to the sensing center 3. Correspondingly, the sensing center 3 receives the third sensing result from the sensing node 7.

[0505] The sensing center 3 can refer to the description of the sensing center in FIG. 1, and will not be repeated here.

[0506] For example, the sensing node 7 can be the sensing node B in FIG. 2f, the sensing center 3 can be the sensing center of the living room in FIG. 2f, and the first target includes a human body. The third sensing result includes the sensing result of the human body. The sensing node B sends the third sensing result to the sensing center of the living room.

[0507] Optionally, the third sensing result is carried in a second frame. The second frame is used to report the sensing result. For example, the second frame is a sensing result reporting frame, or the second frame is a sensing information reporting frame.

[0508] For example, the second frame includes one or more fields, and each field carries parameters as shown in Table 4 or Table 5:

[0509] Table 4

[0510] Table 5

[0511] As shown in Table 4, the second frame includes a CIR feedback field, and the CIR feedback field carries the third sensing result. The third sensing result is CIR data, which is selected by the sensing node 7 according to the first range information.

[0512] As shown in Table 5, the second frame includes a range-doppler feedback field, and the range-doppler feedback field carries the third sensing result. The third sensing result is a range-doppler map, which is selected by the sensing node 7 according to the first range information.

[0513] Optionally, as shown in Table 4 or Table 5, the second frame further includes one or more of the following fields: a sensing signal configuration index field, or a sensing signal parameter field, which can be referred to the introduction of Table 3 and will not be described again.

[0514] It should be pointed out that in the present application, the range-doppler map can also be described as a range-doppler-angle map, range-doppler-angle data, or range-doppler data. The range-doppler field can also be described as a range-doppler feedback field, or a range-doppler-angle feedback field, etc.

[0515] For the sensing center 3, the sensing center 3 acquires the third sensing result, and the sensing center 3 can also acquire the sensing result provided by other sensing nodes, such as the fourth sensing result. In the cooperative sensing mode, the sensing center 3 can perform data association or sensing fusion processing on the third sensing result and the fourth sensing result, thereby obtaining more sensing information of the first target and improving the sensing accuracy and efficiency.

[0516] That is, the rough range where the first target is located, i.e., the above-mentioned first range information, is acquired first, and then the third sensing result is selected and fed back based on the first range information. Since the third sensing result includes the sensing result of the first target, the present application can not only accurately feed back the target sensing result, but also reduce the feedback amount, save resource overhead, improve the sensing feedback efficiency, and also help to reduce the complexity of subsequent data association or sensing fusion and improve the sensing performance.

[0517] It should be supplemented that if the first range information is determined based on a relative coordinate system. As shown in FIG. 13, the sensing node 6 also provides the sensing node 7 with the position information of the first reference point, i.e., the present application also includes S1111:

[0518] S1111, the sensing node 6 sends the position information of the first reference point to the sensing node 7. Correspondingly, the sensing node 7 receives the position information of the first reference point from the sensing node 6.

[0519] The position information of the first reference point is determined based on an absolute coordinate system. For example, the position information of the first reference point includes longitude and latitude of the first reference point.

[0520] Optionally, the position information of the first reference point is carried in the first frame, such as a perception measurement request frame or a perception configuration frame.

[0521] In the case where S1111 is performed, for the perception node 7, S1104 includes: the perception node 7 selects the third perception result according to the first range information and the position information of the first reference point, to adapt to the current perception range.

[0522] For example, the perception node 7 determines the range between the perception node 7 and the first target according to the position information of the first reference point and the first range information, and then selects the third perception result according to the range between the perception node 7 and the first target.

[0523] It is easy to understand that in the present application, S1111 is an optional step. The perception node 6 can perform S1111, or can not perform S1111. For example, if the first range information is determined based on a relative coordinate system, or the perception node 6 pre-configures the position information of the first reference point, the perception node 6 can perform S1111. For another example, if the first range information is determined based on an absolute coordinate system, or the perception node 7 pre-configures the position information of the first reference point, or the protocol pre-defines the position information of the first reference point, the perception node 6 can not perform S1111.

[0524] Further, when the perception node 6 performs S1111, the perception node 6 can first perform S11012, and then perform S1111, or first perform S1111, and then perform S11012, or simultaneously perform S11012 and S1111, without limitation.

[0525] It needs to be supplemented that if the first target is a moving target, as shown in FIG. 13, the perception node 6 further provides the perception node 7 with the moving speed information of the first target, that is, the present application further includes S1121:

[0526] S1121, the perception node 6 sends the moving speed information of the first target to the perception node 7. Correspondingly, the perception node 7 receives the moving speed information of the first target from the perception node 6.

[0527] For example, the moving speed information of the first target can be understood as the moving speed of the first target relative to the first reference point.

[0528] Optionally, the moving speed information of the first target is carried in the first frame, such as a perception measurement request frame or a perception configuration frame.

[0529] In the case where S1121 is performed, for the perception node 7, S1104 comprises: the perception node 7 selects the third perception result according to the first range information and the moving speed information of the first target, to realize the continuous monitoring.

[0530] It is easy to understand that in the present application, S1121 is an optional step. The perception node 6 can perform S1121 or not perform S1121. For example, if the first target is a moving target, the perception node 6 can perform S1121. For another example, if the first target is a stationary target, the perception node 6 can not perform S1121.

[0531] Further, when the perception node 6 performs S1121, the perception node 6 can perform S11012 first and then perform S1121, or perform S1121 first and then perform S11012, or perform S11012 and S1121 at the same time, which is not limited.

[0532] In some embodiments, as shown in FIG. 13, the perception node 6 also provides the first confidence information to the perception node 7, that is, the present application also comprises S1131:

[0533] S1131, the perception node 6 sends the first confidence information to the perception node 7. Correspondingly, the perception node 7 receives the first confidence information from the perception node 6.

[0534] The first confidence information indicates the probability that the range where the first target is located is the first range information.

[0535] Optionally, the first confidence information is carried in the first frame, such as the perception measurement request frame or the perception configuration frame.

[0536] In the case where S1131 is performed, for the perception node 7, S1104 comprises: the perception node 7 selects the third perception result according to the first range information and the first confidence information, to improve the target perception efficiency.

[0537] For example, in the case where the first confidence information is greater than a first threshold, the perception node 7 selects the third perception result according to the first range information. On the contrary, in the case where the first confidence information is less than or equal to the first threshold, the perception node 7 does not need to select the third perception result according to the first range information, does not perform the selection process of the third perception result, and reduces unnecessary processing. The first threshold can be 0.6, 0.6 or 0.75, etc. The first threshold can be determined according to historical experience value, which is not limited.

[0538] It is easy to understand that in the present application, S1131 is an optional step. The perception node 6 can perform S1131 or not. For example, if the current data transmission amount is small and the communication resource is relatively idle, the perception node 6 can perform S1131. For another example, if the current data transmission amount is large and the communication resource is relatively tight, the perception node 6 can not perform S1131.

[0539] Further, when the perception node 6 performs S1131, it can first perform S11012 and then perform S1131, or first perform S1131 and then perform S11012, or perform S11012 and S1131 at the same time, which is not limited.

[0540] In some embodiments, as shown in FIG. 13, the perception node 6 also provides the perception task type to the perception node 7, that is, the present application also includes S1141:

[0541] S1141, the perception node 6 sends the first information to the perception node 7. Correspondingly, the perception node 7 receives the first information from the perception node 6.

[0542] The first information indicates the perception task type of the first target perception.

[0543] Optionally, the first information is carried in a first frame, such as a perception measurement request frame or a perception configuration frame.

[0544] In the case where S1141 is performed, for the perception node 7, S1104 includes: the perception node 7 selects a third perception result according to the first range information and the perception task type to adapt to the current perception task and the perception range.

[0545] For example, in the case where the perception task type is a first task type, the perception node 7 selects measurement data with a larger signal amplitude as the third perception result according to the first range information.

[0546] For another example, in the case where the perception task type is a second task type, the perception node 7 selects measurement data with a smaller signal amplitude as the third perception result according to the first range information.

[0547] It is easy to understand that in the present application, S1141 is an optional step. The perception node 6 can perform S1141 or not. For example, in the case where the perception node 6 pre-configures the perception task type, the perception node 6 can perform S1141. For another example, in the case where the perception node 7 pre-configures the perception task type or the protocol pre-defines the perception task type, the perception node 6 can not perform S1141.

[0548] Further, when the perception node 6 performs S1141, S11012 can be performed first, then S1141 is performed, S11012 can be performed first, then S1141 is performed, S11012 and S1141 can be performed at the same time, and no limitation is given.

[0549] It should be noted that in the present application, taking FIGS. 3-13 as an example, the processing procedures of different perception nodes of the perception system are described. Of course, the above processing procedures can also be used in the WiFi system. For example, the perception center can be replaced by an access point (AP), and the perception perception node can be replaced by a station (STA). In addition, in the WiFi system, there is also a sensing by proxy (SBP) STA, which can be denoted as SBP STA. Among them, the SBP STA does not have sensing capability. In this case, proxy sensing can be implemented based on the AP and the STA, and the specific process is as follows:

[0550] Step 1, the AP sends information A to the SBP STA. Correspondingly, the SBP STA receives the information A from the AP.

[0551] Among them, the information A includes the first range information. Optionally, the information A also includes the sensing task type corresponding to the first range information.

[0552] Step 2, the SBP STA confirms to sense the first range information.

[0553] Step 3, the SBP STA sends a sensing request to the AP. Correspondingly, the AP receives the sensing request from the SBP STA.

[0554] Among them, the sensing request includes the first range information to request sensing the first range information.

[0555] Step 4, in response to the sensing request, the AP and the STA perform sensing measurement to obtain sensing result A.

[0556] Step 5, the AP sends the sensing result A to the SBP STA. Correspondingly, the SBP STA receives the sensing result A from the AP, thereby realizing proxy sensing.

[0557] It can be understood that, in the above various embodiments, the methods and / or steps implemented by different sensing nodes (such as sensing node 1-sensing node 5) can also be implemented by components (for example, processors, chips, chip systems, circuits, logic modules, or software) available to the sensing nodes; the methods and / or steps implemented by the sensing centers (such as sensing center 1-sensing center 2) can also be implemented by components (for example, processors, chips, chip systems, circuits, logic modules, or software) available to the sensing centers. Among them, the chip system can be composed of a chip, or the chip system can include a chip and other discrete devices.

[0558] It can be understood that, in order to implement the above functions, the communication device includes hardware structures and / or software modules corresponding to the implementation of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of the examples described in the embodiments disclosed in the present application, the present application can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is driven by hardware or computer software to drive hardware depends on the specific application and design constraints of the technical solution. Professional technicians can use different methods for each specific application to implement the described functions, but such implementation should not be considered beyond the scope of the present application.

[0559] The embodiments of the present application can divide the functional modules of the communication device according to the method embodiments described above, for example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The integrated module can be realized in the form of hardware or software function module. It should be pointed out that the division of modules in the embodiments of the present application is illustrative, and is only a logical function division. Actual implementation can have another division method.

[0560] FIG. 14 shows a structural schematic diagram of a communication device 1400. The communication device 1400 includes a processing module 1401 and a transceiver module 1402. The communication device 1400 can be used to implement the functions of the sensing nodes or sensing centers described above.
