To enhance the service capabilities in these scenarios, the concept of integrated sensing and communication (ISAC) has been proposed.

[0007] Based on the method provided in the first aspect above, the perception management device can predict the position of the first target at the second moment and obtain the first perception information. Among them, the first perception information is obtained for the second moment and the aforementioned predicted position, which is more targeted, so it can increase the probability of detecting the first target and make the obtained first perception information more accurate. Subsequently, the perception management device can determine the actual position of the first target at the second moment based on the first perception information. Since the first perception information is more accurate, the actual position of the first target at the second moment obtained based on the first perception information is also more accurate. Therefore, the method provided in the first aspect above can improve the probability of detecting the first target and the positioning accuracy.

[0008] In a possible implementation, obtaining the first perception information includes: sending the first position information to a first perception device; and receiving the first perception information from the first perception device.

[0106] Before introducing the technical solution of this application, the relevant technical terms involved in this application are explained. It is understood that these explanations are intended to make this application easier to understand and should not be regarded as limiting the scope of protection claimed in this application.

[0107] 1. Sensing device

[0108] The sensing devices in this application, such as sensing device 202, sensing device 205, the first sensing device, or the second sensing device in the following embodiments, have sensing and communication capabilities and can sense a target by transmitting signals. For example, the sensing device can transmit a signal and receive a reflected signal (or echo signal) of the signal, and sense the target based on the reflected signal to obtain sensing information of the target. Exemplarily, the sensing device is a network device or a terminal.

[0109] The network device in this application may also be referred to as a radio access network (RAN) device or RAN node, etc. The network device includes, but is not limited to, an evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in long term evolution (LTE), an evolved base station (next generation eNB, ng-eNB) in next generation LTE, a base station (gNodeB or gNB) in new radio (NR), a transmitting point (TP) or a transmission receiving point (TRP), a base station in subsequent evolution of 3GPP, a next generation base station (next generation NodeB, gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, an access node in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, an integrated access and backhaul (IAB) node, etc. Among them, the base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. Multiple base stations can support networks of the same technology mentioned above, or they can support networks of different technologies mentioned above. The base station can include one or more co-sited or non-co-sited TRPs. The network device can also be a device that acts as a base station in device-to-device (D2D) communication, vehicle-to-vehicle communication, drone communication, and machine communication. The network device can also be a wireless controller in a cloud radio access network (CRAN) scenario. The RAN node can also be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), a radio unit (RU), a road side unit (RSU) with base station function, a wired access gateway, or a core network element, etc. The network device can also be a server, a wearable device, a machine communication device, or an in-vehicle device, etc. For example, a network device in vehicle to everything (V2X) technology may be a road side unit (RSU).

[0110] In this application, the CU and DU may be separately configured or may be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understood that the CU may be classified as a network device in an access network, or as a network device in a core network, without limitation herein.

[0111] It is understandable that in different systems, CU (or CU-CP and CU-UP), DU or RU may have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be referred to as O-CU (open CU), DU may also be referred to as O-DU, CU-CP may also be referred to as O-CU-CP, CU-UP may also be referred to as O-CU-UP, and RU may also be referred to as O-RU. In addition, any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0112] The terminal in this application can be deployed on land, including indoors, outdoors, handheld or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal can also be called a terminal device, and the terminal device can be a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., or a device for providing voice or data connectivity to users. Among them, UE includes a handheld device with wireless communication function, a vehicle-mounted device (for example, a device set in a car, bicycle, electric car, airplane, ship, train, high-speed rail, etc.), a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.) or a computing device. Exemplarily, the UE can be a mobile phone, a mobile internet device (MID) or a computer with wireless transceiver function. A UE may also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless modem, a smart point of sale (POS) machine, customer-premises equipment (CPE), an intelligent robot, a robotic arm, workshop equipment, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, an on-board terminal, a roadside unit (RSU) with terminal functions, or an aerial device (e.g., an intelligent robot, a hot air balloon, a drone, an airplane), etc. A terminal may also be other devices with terminal functions, for example, a terminal may also be a device that functions as a terminal in D2D communication.

[0113] The terminal of the present application can be an on-board module, on-board module, on-board component, on-board chip or on-board unit built into a vehicle as one or more components or units, and the vehicle can implement the method of the present application through the built-in on-board module, on-board module, on-board component, on-board chip or on-board unit. Therefore, the present application can be applied to vehicle networking, such as vehicle to everything (V2X), long-term evolution vehicle (LTE-V), vehicle to vehicle (V2V), etc.

[0114] It is understandable that in some scenarios, the roles of network devices and terminals are relative. For example, a helicopter or drone, which is usually configured as a terminal, can also be configured as a mobile base station, and the device that accesses the network device via the helicopter or drone is configured as a terminal.

[0115] In this application, the sensing device can be set as needed. For example, in some scenarios, in order to ensure that the sensing device has a sufficient direct line of sight, the sensing device can be set on a roadside object such as a street lamp or a roadside tree.

[0116] 2. Array orientation of the sensing device (hereinafter referred to as array orientation)

[0117] In this application, the array face direction refers to the direction of the antenna array face of the sensing device (hereinafter referred to as the antenna array face). It is understandable that the array face direction can be expressed in various ways. This application uses the horizontal azimuth angle, downtilt angle, and tilt angle shown in Figure 1A as an example for explanation.

[0118] As an example, the array face orientation is represented by the horizontal azimuth angle α, downtilt angle β, and tilt angle γ of the local coordinate system where the antenna array face is located relative to the three-dimensional global coordinate system. For example, in Figure 1A, the global coordinate system o-xyz is transformed to the local coordinate system where the antenna array face 101 is located The process includes: first rotating the global coordinate system o-xyz around the z axis by an angle α to obtain the coordinate system o- Then the coordinate system by The axis is rotated by an angle β to obtain the coordinate system Then the coordinate system by The axis is rotated by an angle γ to obtain the coordinate system That is the local coordinate system where the antenna array surface 101 is located. In the figure, the normal direction of the antenna array 101 points to In the positive direction of the axis, the two edges of the antenna array 101 are located Axis and On axis.

[0119] 3. Goal

[0120] The targets in this application, such as target 203, the first target, or the second target in the following embodiments, are people or objects that can be sensed by a sensing device and are mobile. The targets may or may not have communication capabilities. For example, targets include, but are not limited to, people, various vehicles, or the various terminals described above. Vehicles can be used to transport people or goods, such as vehicles, trains, high-speed trains, airplanes, or drones.

[0121] 4. Target azimuth

[0122] In this application, the azimuth angle of the target is the angle between the target's orientation and the antenna array of the sensing device. It is understandable that the azimuth angle of the target can be expressed in many ways. This application uses the zenith angle and horizontal azimuth angle shown in Figure 1B as an example for explanation.

[0123] As an example, the azimuth angle of the target can be represented by the zenith angle and the horizontal azimuth angle. For example, in Figure 1B, the target is located at point A, the antenna array surface 111 is located in the yoz plane, and the positive direction of the x-axis is the normal direction of the antenna array surface 111. The azimuth angle of the target is the angle between oA and the antenna array surface 111, which can be obtained by the angle θ between oA and the z-axis (i.e., the zenith angle corresponding to point A or oA), and the angle between the projection oa of oA on the xoy plane and the x-axis. (i.e. the horizontal azimuth angle corresponding to point A or oA). That is, the azimuth angle of the target can be expressed as (θ, ).

[0124] 5. Beamforming

[0125] In this application, the sensing device includes a multi-antenna array capable of beamforming, focusing transmission power in the direction of the beam. Consequently, compared to a non-beamforming beam, the transmission power in the direction of the beam can be higher. For example, the sensing device can adjust antenna weights to form one or more transmit beams and / or one or more receive beams in space. Transmit beams are used to transmit signals, while receive beams are used to receive signals. It will be appreciated that the directions of the transmit and receive beams can be the same or different.

[0126] For example, in Figure 1C , the sensing device transmits four beams, namely beams 121 to 124. Beams 121 to 124 are either transmit beams or receive beams; alternatively, beams 121 and 122 are transmit beams, and beams 123 and 124 are receive beams; alternatively, beams 121 to 123 are transmit beams, and beam 124 is a receive beam; alternatively, at time 1, beam 121 is a receive beam, and at time 2, beam 121 is a transmit beam, without limitation.

[0127] In this application, beamforming may also be referred to as beamforming or spatial filtering.

[0128] 6. Perception Mode

[0129] In this application, a sensing mode refers to the mode in which a sensing device senses a target, including single-station sensing mode, dual-station sensing mode, or multi-station sensing mode. Single-station sensing mode, dual-station sensing mode, and multi-station sensing mode are distinguished based on the number of sensing devices and whether the devices transmitting and receiving signals are the same. This is explained in detail below.

[0130] Single-station sensing mode refers to a mode in which a single sensing device senses a target. In single-station sensing mode, the same device transmits and receives signals. For example, in Figure 1D, the sensing device transmits a signal and receives a reflection of that signal, sensing the target based on the received reflection.

[0131] Bistatic sensing mode involves sensing a target using two sensing devices. In bistatic sensing mode, the transmitting and receiving devices are different. For example, in Figure 1E , sensing device 1 transmits a signal, while sensing device 2 receives a reflection of that signal and senses the target based on the reflection.

[0132] Multi-station sensing mode refers to a mode in which three or more sensing devices are used to sense targets. Some of these sensing devices are used to transmit signals, while others are used to receive reflected signals from these signals and sense targets based on these reflected signals. For example, in the case of three sensing devices, one sensing device transmits a signal, while the other two receive reflected signals from this signal and sense targets based on these reflected signals. Alternatively, two sensing devices transmit a signal, while another receives reflected signals from each of the two previously transmitted signals and senses targets based on these reflected signals.

[0133] This application primarily uses single-station sensing mode and dual-station sensing mode sensing targets as examples to illustrate. The logic of multi-station sensing mode sensing targets is similar to that of dual-station sensing mode sensing targets, differing in the number of sensing devices that transmit signals and / or the number of sensing devices that receive signals. Therefore, the introduction to multi-station sensing mode sensing targets can refer to the description of dual-station sensing mode sensing targets in this application and will not be repeated here.

[0134] As mentioned above, the sensing device can sense the target, and therefore, the target can be detected based on the sensing device. For example, the position of the target can be detected by the following three methods.

[0135] Method 1: Referring to Figure 1F , at least two sensing devices, such as Sensing Device 1 and Sensing Device 2, transmit signals to a target. Upon receiving the signals, the target determines the transmission delay of each signal and transmits the delay to a positioning device. The positioning device then determines the target's location based on the received delays and the positions of the at least two sensing devices.

[0136] In Method 1, the positioning device can determine the target's location. However, the target must have communication capabilities, so Method 1 is only applicable in scenarios where the target has communication capabilities. Furthermore, the sensing device typically transmits signals via broadcast, resulting in lower power at the target and a lower signal-to-noise ratio. Consequently, the target's estimated transmission delay is less accurate, which in turn affects the positioning device's accuracy.

[0137] Method 2: Referring to Figure 1G , the sensing device transmits a signal and receives its reflection, determining the signal's transmission delay and the target's azimuth. The sensing device then sends this information to the sensing management device. The sensing management device then determines the target's location based on the transmission delay, the target's azimuth, and the sensing device's position.

[0138] In method 2, the sensing management device can determine the location of the target, and the target may not have communication capabilities, so method 2 is applicable not only to scenarios where the target has communication capabilities, but also to scenarios where the target does not have communication capabilities. However, when the target does not have communication capabilities or the radar cross section of the target is small, for example, when the target is a person or a drone, the signal power reflected back to the sensing device is weak, resulting in a low received power of the reflected signal and a low received signal-to-noise ratio of the reflected signal, which results in inaccurate information perceived by the sensing device (such as the signal transmission delay and the azimuth of the target), which in turn has a certain impact on the probability of the sensing management device detecting the target and the positioning accuracy of the target.

[0139] Method 3: The perception management device predicts the location of the target at time 1 (hereinafter referred to as the predicted location), obtains first perception information, and determines the actual location of the target at time 1 based on the first perception information. The first perception information is information about the target perceived at time 1 based on the predicted location.

[0140] In method 3, the perception management device can determine the actual position of the target at time 1, and the target may not have communication capabilities, so method 3 is applicable not only to scenarios where the target has communication capabilities, but also to scenarios where the target does not have communication capabilities. In addition, the first perception information is perceived at time 1 based on the predicted position, that is, the first perception information is obtained for a specific time and a specific position, which is more targeted, so the first perception information is more accurate. Therefore, the perception management device determines the actual position of the target at time 1 based on the first perception information, which can improve the probability of detecting the target and the positioning accuracy. The specific implementation of method 3 will be specifically described in the methods shown in Figures 5 and 6 below, and will not be repeated here.

[0141] It can be understood that the method provided in the present application can be used in various communication systems. For example, the communication system can be an LTE system, a fifth generation (5G) communication system, a wireless fidelity (WiFi) system, a third generation partnership project (3GPP) related communication system, a future evolutionary communication system (such as a sixth generation (6G) communication system, etc.), or a system integrating multiple systems, etc., without limitation. Among them, 5G can also be referred to as NR. The method provided in the present application is described below using the communication system 20 shown in Figure 2 as an example. Figure 2 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in the present application.

[0142] As shown in Figure 2, it is a schematic diagram of the architecture of the communication system 20 provided in this application. In Figure 2, the communication system 20 includes at least one perception management device 201 (Figure 2 shows only one), a perception device 202 in communication with the perception management device 201, and a target 203 located within the perception area of ​​the perception device 202. Optionally, the communication system 20 also includes a perception device 204 in communication with the perception management device 201. Optionally, the target 203 is also located within the perception area of ​​the perception device 204. Optionally, the perception device 202 and the perception device 204 are in communication with each other.

[0143] The perception management device in this application, such as perception management device 201, is a device with communication and computing capabilities, such as a server, cloud server, core network element, access network element, cloud, or computing device with communication capabilities, without limitation. The introduction of perception device 202, perception device 205, and target 203 can refer to the description of perception devices and targets above and will not be repeated here.

[0144] Optionally, the communication system 20 further includes a positioning device 205 for determining the location of the sensing device 202 and / or the sensing device 205, and indicating the location to the sensing management device 201. Exemplarily, the positioning device 205 is a device with communication and computing capabilities, such as a server, a cloud server, a core network element, an access network element, a cloud, or a computing device with communication capabilities, without limitation.

[0145] In Figure 2, the perception management device, the positioning device, and the perception device are different physical devices. However, in specific applications, at least two of the logical functions of the perception management device, the logical functions of the positioning device, and the logical functions of the perception device can be integrated into the same physical device. For example, the logical functions of the perception management device 201 are integrated into the perception device 202 or the perception device 205. In this case, the perception device 202 or the perception device 205 has the logical functions of the perception management device 201 and can perform the operations of the perception management device 201, such as determining the position of the target based on the perception information of the target. Similarly, the logical functions of the positioning device 205 can be integrated into the perception device 202 or the perception device 205, or both the logical functions of the perception management device 201 and the logical functions of the positioning device 205 can be integrated into the perception device 202 or the perception device 205.

[0146] It is understandable that the communication system 20 shown in FIG2 is for example only and is not intended to limit the technical solution of the present application. Those skilled in the art should understand that, in the specific implementation process, the communication system 20 may also include other devices, and the number of sensing management devices, sensing devices, targets or positioning devices may also be determined according to specific needs without limitation. For example, the communication system 20 may also include sensing devices other than the sensing device 202 and the sensing device 205, such as the sensing device 206 (not shown in FIG2 , but shown in FIG3E below).

[0147] It is understandable that the communication system 20 can be applied to a variety of different communication scenarios. This application uses the communication scenarios shown in Figures 3A to 3E as examples for explanation.

[0148] Based on the above introduction, we can understand that the sensing device can be a terminal or a network device, etc., and the sensing mode includes a single-station sensing mode or a dual-station sensing mode, etc. Therefore, the communication scenarios can be divided based on the type of sensing device and the sensing mode.

[0149] Communication scenario 31: Communication system 20 includes a sensing management device 201, a sensing device 202, and a target 203. The sensing device 202 is a network device, and the sensing mode includes a single-station sensing mode.

[0150] Exemplarily, the communication system 20 can be applied to the communication scenario 31 shown in Figure 3A. In Figure 3A, the sensing device 202 can obtain sensing information of the target 203 through the single-station sensing mode and send the sensing information to the sensing management device 201 so that the sensing management device 201 can locate the target 203.

[0151] Communication scenario 32: Communication system 20 includes a sensing management device 201, a sensing device 202, a sensing device 204, and a target 203. Sensing device 202 is a network device, sensing device 204 is a terminal, and the sensing mode includes a single-station sensing mode.

[0152] For example, communication system 20 can be applied to communication scenario 32 shown in Figure 3B . In Figure 3B , sensing device 202 can configure communication resources for sensing device 204, so that sensing device 204 uses the communication resources to acquire sensing information of target 203 using a single-station sensing mode. Subsequently, sensing device 204 can transmit this sensing information to sensing management device 201, allowing sensing management device 201 to locate target 203.

[0153] Communication scenario 33: Communication system 20 includes a sensing management device 201, a sensing device 202, a sensing device 204, and a target 203. Sensing device 202 and sensing device 204 are network devices, and the sensing mode includes a dual-station sensing mode.

[0154] For example, communication system 20 can be applied to communication scenario 33 shown in FIG3C . In FIG3C , sensing device 202 and sensing device 204 sense target 203 using a dual-station sensing mode. Sensing device 202 or sensing device 204 can obtain sensing information about target 203 and transmit this sensing information to sensing management device 201, enabling sensing management device 201 to locate target 203. It will be appreciated that in FIG3C , sensing device 202 transmits a signal and sensing device 204 receives a reflected signal of the signal; alternatively, sensing device 204 transmits a signal and sensing device 202 receives a reflected signal of the signal.

[0155] Communication scenario 34: Communication system 20 includes a sensing management device 201, a sensing device 202, a sensing device 204, and a target 203. Sensing device 202 is a network device, sensing device 204 is a terminal, and the sensing mode includes a dual-station sensing mode.

[0156] For example, communication system 20 can be applied to communication scenario 34 shown in FIG3D . In FIG3D , sensing device 202 configures communication resources for sensing device 204, so that sensing device 204 uses the communication resources and sensing device 202 to perceive target 203 using a dual-station sensing mode. Sensing device 202 or sensing device 204 can obtain sensing information about target 203 and transmit this sensing information to sensing management device 201, so that sensing management device 201 can locate target 203. It will be appreciated that in FIG3D , sensing device 202 transmits a signal and sensing device 204 receives a reflection of the signal; alternatively, sensing device 204 transmits a signal and sensing device 202 receives a reflection of the signal.

[0157] Communication scenario 35: Communication system 20 includes a sensing management device 201, a sensing device 202, a sensing device 204, a sensing device 206, and a target 203. Sensing device 202 is a network device, sensing devices 204 and 206 are terminals, and the sensing mode includes a dual-station sensing mode.

[0158] For example, communication system 20 can be applied to communication scenario 35 shown in FIG3E . In FIG3E , sensing device 202 configures communication resources for sensing device 204 and sensing device 206, respectively, so that sensing device 204 and sensing device 206 perceive target 203 using a dual-station sensing mode based on the configured communication resources. Sensing device 204 or 206 can obtain sensing information of target 203 and transmit this sensing information to sensing management device 201, so that sensing management device 201 can locate target 203. It will be appreciated that in FIG3E , sensing device 204 transmits a signal and sensing device 206 receives a reflected signal of the signal; alternatively, sensing device 206 transmits a signal and sensing device 204 receives a reflected signal of the signal.

[0159] Optionally, the above-mentioned communication scenario 31, communication scenario 32, communication scenario 33, communication scenario 34 or communication scenario 35 further includes a positioning device 205.

[0160] It can be understood that the above-mentioned communication scenarios 31 to 35 are only examples of communication scenarios. In specific applications, the communication system 20 can also be applied to other communication scenarios without limitation.

[0188] It can be understood that the method provided below in this application uses the perception management device and the perception device as an example of the execution subject of the interaction diagram to illustrate the method, but this application does not limit the execution subject of the interaction diagram. For example, the perception management device in the method provided in the following embodiment of this application can also be a chip, chip system, or processor that supports the perception management device to implement the method, or a logical node, logical module, or software that can implement all or part of the functions of the perception management device; the perception device in the method provided below in this application can also be a chip, chip system, or processor that supports the perception device to implement the method, or a logical node, logical module, or software that can implement all or part of the functions of the perception device.

[0189] As shown in FIG5 , a target detection method provided by the present application may include the following steps:

[0190] S501: The perception management device obtains first location information of a first target at a first moment.

[0191] The perception management device may be the perception management device 201 in the communication system 20 shown in FIG. 2 , and the first target may be the target 203 in the communication system 20 .

[0192] In this application, the first location information can be used to indicate the location of the first target at a second moment. The second moment is later than the first moment. That is, the perception management device can predict the location of the first target at a second moment after the first moment at the first moment. The specific process of the perception management device predicting the location of the first target at a second moment after the first moment at the first moment will be described in S5011-S5012 below and will not be repeated here.

[0193] In one possible design, the first position information includes the predicted coordinates of the first target's position at the second moment, or the predicted azimuth of the first target at the second moment. The coordinates are two-dimensional or three-dimensional coordinates, and the representation of the predicted azimuth of the first target at the second moment can refer to the description of the target's azimuth above.

[0194] Exemplarily, the first position information includes (x1, y1), wherein x1 represents the horizontal coordinate of the predicted position of the first target at the second moment in the two-dimensional coordinate system, and y1 represents the vertical coordinate of the predicted position of the first target at the second moment in the two-dimensional coordinate system. Alternatively, the first position information includes (x1, y1, z1), wherein x1 represents the horizontal coordinate of the predicted position of the first target at the second moment in the three-dimensional coordinate system, y1 represents the vertical coordinate of the predicted position of the first target at the second moment in the three-dimensional coordinate system, and z1 represents the vertical coordinate of the predicted position of the first target at the second moment in the three-dimensional coordinate system. Alternatively, the first position information includes (θ1, ), where θ1 represents the zenith angle corresponding to the predicted position of the first target at the second moment, Indicates the horizontal azimuth angle corresponding to the predicted position of the first target at the second moment. Alternatively, the first position information includes (θ1, D1), where D1 represents the distance between the predicted position of the first target at the second moment and the first sensing device, or represents the distance between the predicted position of the first target at the second moment and the sensing management device, or represents the distance between the predicted position of the first target at the second moment and the coordinate system where the first target is located (such as θ1 and The distance between the origins in the coordinate system where the

[0195] In a possible implementation manner, the perception management device obtains the first location information periodically or aperiodically.

[0196] It is understandable that if the perception management device periodically obtains the first location information, the period for obtaining the first location information may be protocol-defined or pre-defined, and the period is related to the business and / or the moving speed of the first target. For example, when other conditions are fixed, the business has higher real-time requirements for the location of the first target, and the shorter the period; the business has lower real-time requirements for the location of the first target, and the longer the period. For another example, when other conditions are fixed, the faster the moving speed of the first target, the shorter the period; and the slower the moving speed of the first target, the longer the period.

[0197] S502: The perception management device obtains first perception information.

[0198] In this application, the first perception information is used to indicate information about the first target perceived at the second moment based on the first position information. In other words, the first perception information is obtained by perceiving the first target at a specific moment (i.e., the second moment) and a specific position (i.e., the position indicated by the first position information), so the first perception information is relatively accurate.

[0199] In one possible design, the first perception information includes first angle information or second position information.

[0200] In the present application, the first angle information is used to indicate the azimuth between the first target and the first sensing device at the second moment, and the azimuth can represent the position of the first target relative to the first sensing device at the second moment. Therefore, the first angle information can be used by the sensing management device to determine the actual position of the first target at the second moment. The second position information can be used to indicate the position of the first target at the second moment. The representation method of the second position information can refer to the above introduction to the first position information and will not be repeated here. The second position information can be used by the sensing management device to determine the actual position of the first target at the second moment. It should be understood that the position indicated by the second position information is the same as or different from the actual position. In other words, after the sensing management device obtains the second position information, it can determine the position indicated by the second position information as the actual position of the first target at the second moment, or further process the second position information to obtain the above actual position, such as combining the information perceived by the sensing device other than the sensing device that perceives the first sensing information, and / or the position of the first target at a historical moment to determine the above actual position, without limitation.

[0201] Exemplarily, the first angle information includes the angle between the reflected signal of the first sensing signal and the antenna array of the first sensing device. The first sensing signal is a signal used to sense the first target (such as a signal for sensing the first target at the second moment), and the reflected signal of the first sensing signal is a signal after the first sensing signal reaches the first target and is reflected by the first target. It can be understood that for the single-station sensing mode, the first sensing signal is sent by the first sensing device, and the reflected signal of the first sensing signal is a signal after the first sensing signal reaches the first target and is reflected by the first target and reaches the first sensing device. For the dual-station sensing mode, the first sensing signal is sent by the third sensing device, and the reflected signal of the first sensing signal is a signal after the first sensing signal reaches the first target and is reflected by the first target and reaches the first sensing device.

[0202] For example, the first angle information includes (θ2, ). Wherein, θ2 represents the zenith angle corresponding to the reflected signal of the first perception signal, Indicates the horizontal azimuth angle corresponding to the reflected signal of the first perception signal. Taking the coordinate system shown in FIG1B as an example, if the direction from A to o is the transmission direction of the reflected signal of the first perception signal, the zenith angle corresponding to the reflected signal of the first perception signal is θ in FIG1B, and the horizontal azimuth angle corresponding to the reflected signal of the first perception signal is Alternatively, the first angle information includes (θ2, D2), where D2 represents the distance between the position of the first target at the second moment and the first sensing device.

[0203] Optionally, the first perception information further includes at least one of the following: information at the second moment, first indication information, first delay information, or first Doppler information. The above information is introduced below respectively.

[0204] In the present application, the information of the second moment is used to indicate the second moment. For example, the information of the second moment includes the second moment, or includes the difference between the second moment and the reference moment, or includes information about the time domain resources where the second moment is located. Among them, the reference moment is a moment defined in the protocol or a pre-set moment. The information about the time domain resources where the second moment is located includes an identifier of the time slot where the second moment is located, or includes an identifier of the symbol where the second moment is located and an identifier of the time slot where the symbol is located, or includes an identifier of the symbol where the second moment is located, an identifier of the time slot where the symbol is located, and an identifier of the subframe where the time slot is located, or includes an identifier of the symbol where the second moment is located, an identifier of the time slot where the symbol is located, an identifier of the subframe where the time slot is located, and an identifier of the frame where the subframe is located. Optionally, the second moment is determined by the perception management device as needed.

[0205] In this application, the first indication information is used to indicate whether the first target is detected at the second moment. For example, the first indication information includes 1 bit. When the value of the 1 bit is "0", it indicates that the first target is not detected at the second moment. When the value of the 1 bit is "1", it indicates that the first target is detected at the second moment, and vice versa.

[0206] In this application, the first delay information is used to indicate the transmission delay of the first sensing signal. For example, in a single-station sensing mode, the transmission delay of the first sensing signal is the duration between the first sensing device transmitting the first sensing signal and receiving the reflected signal of the first sensing signal. In a multi-station sensing mode, the transmission delay of the first sensing signal is the duration between the third sensing device transmitting the first sensing signal and the first sensing device receiving the reflected signal of the first sensing signal.

[0207] In one possible design, the first delay information includes the transmission delay of the first perception signal, or includes the time when the first perception device sends the first perception signal and the time when the reflected signal of the first perception signal is received, or includes the time when the third perception device sends the first perception signal and the time when the first perception device receives the reflected signal of the first perception signal.

[0208] In the present application, the first Doppler information is used to indicate the Doppler frequency shift of the first sensing signal. For example, the first Doppler information includes the Doppler frequency shift.

[0209] It can be understood that the information at the second moment can be used by the perception management device to determine the second moment, thereby knowing that the position of the first target at the second moment is determined. The first indication information can be used by the perception management device to determine whether the first target is detected at the second moment. The first delay information can be used by the perception management device to determine the transmission delay of the first perception signal, thereby assisting in determining the position information of the first target at the second moment to improve positioning accuracy. The first Doppler information can be used by the perception management device to determine the Doppler frequency shift of the first perception signal, thereby determining the movement speed of the first target at the second moment based on the Doppler frequency shift. Optionally, the perception management device can also determine the movement direction of the first target at the second moment based on the Doppler frequency shift.

[0210] The specific process of the perception management device obtaining the first perception information will be introduced in the following S5021-S5022 and will not be repeated here.

[0211] S503: The perception management device determines the location information of the first target at the second moment based on the first perception information.

[0212] In the present application, the position information of the first target at the second moment is used to indicate the actual position of the first target at the second moment.

[0213] In one possible design, the location information includes the coordinates of the actual position of the first target at the second moment, or the actual azimuth of the first target at the second moment. The coordinates are two-dimensional coordinates or three-dimensional coordinates. The coordinate system corresponding to the location information in S503 and the coordinate system corresponding to the first location information in S501 can be the same or different. The method for expressing the actual azimuth of the first target at the second moment can refer to the description of the target's azimuth above.

[0214] Exemplarily, the position information includes (x2, y2), wherein x2 represents the horizontal coordinate of the actual position of the first target at the second moment in the two-dimensional coordinate system, and y2 represents the vertical coordinate of the actual position of the first target at the second moment in the two-dimensional coordinate system. Alternatively, the position information includes (x2, y2, z2), wherein x2 represents the horizontal coordinate of the actual position of the first target at the second moment in the three-dimensional coordinate system, y2 represents the vertical coordinate of the actual position of the first target at the second moment in the three-dimensional coordinate system, and z2 represents the vertical coordinate of the actual position of the first target at the second moment in the three-dimensional coordinate system. Alternatively, the position information includes (θ3, D2), where θ3 represents the zenith angle corresponding to the actual position of the first target at the second moment, represents the horizontal azimuth angle corresponding to the actual position of the first target at the second moment, D2 represents the distance between the actual position of the first target at the second moment and the first sensing device, or represents the distance between the actual position of the first target at the second moment and the sensing management device, or represents the distance between the actual position of the first target at the second moment and the coordinate system where the first target is located (such as θ3 and The distance between the origins in the coordinate system where the

[0215] In one possible implementation, the perception management device determines the location information of the first target at the second moment based on the second location information included in the first perception information.

[0216] In another possible implementation, the perception management device determines the position information of the first target at the second moment based on the first perception information, the position information of the first perception device, and the array orientation information of the first perception device.

[0217] For example, the perception management device determines the position of the first perception device based on the position information of the first perception device, determines the array orientation of the first perception device based on the array orientation information of the first perception device, and determines the position information of the first target at the second moment based on the position, the first perception information (such as the first angle information included therein, or the first angle information and first time delay information included therein) and the array orientation of the first perception device.

[0218] Optionally, before S503, the perception management device obtains the array orientation information of the first perception device. For example, the first perception device sends the array orientation information to the perception management device, and the perception management device receives the array orientation information, thereby obtaining the array orientation information. Alternatively, the perception management device stores the array orientation information and can obtain the array orientation information locally.

[0219] Optionally, before S503, the perception management device obtains the location information of the first perception device. For example, a positioning device (such as positioning device 205 in Figure 2) sends the location information of the first perception device to the perception management device, and the perception management device receives the location information, i.e., obtains the location information. Alternatively, the perception management device stores the location information and can obtain the location information locally.

[0220] Optionally, the perception management device may further determine the velocity of the first target at the second moment based on the first perception information. For example, when the first perception information includes first angle information and first Doppler information, the perception management device may determine the position information of the first target at the second moment based on the first angle information, and determine the velocity of the first target at the second moment based on the first Doppler information.

[0221] Optionally, when determining the location information of the first target at the second moment, the perception management device may also refer to the location information of the first target at a moment before the second moment (i.e., a historical moment), so that the determined location information is more accurate. For example, if the perception management device determines the location of the first target at 8:00 according to S501-S503 above, when determining the location of the first target again at 8:05, the perception management device may refer to the location of the first target determined at 8:00.

[0222] It is understood that the above steps S501-S503 are the specific process by which the perception management device determines the location information of the first target at the second moment. In a specific application, in addition to the first target, there are other targets, such as the second target. The perception management device can use a method similar to the above steps S501-S503 to determine the location of the second target.

[0223] It is understandable that the perception management device may repeatedly execute the above S501-S503 to achieve tracking of the first target.

[0224] It can be understood that the actions of the perception management device in the above S501-S503 can be executed by the processor 401 in the communication device 40 shown in Figure 4 calling the application code stored in the memory 403, and this application does not impose any restrictions on this.

[0225] Based on the method shown in Figure 5, the perception management device can predict the position of the first target at the second moment and obtain the first perception information. Among them, the first perception information is obtained for the second moment and the predicted position, which is more targeted, so it can increase the probability of detecting the first target and make the obtained first perception information more accurate. Subsequently, the perception management device can determine the actual position of the first target at the second moment based on the first perception information. Since the first perception information is more accurate, the actual position of the first target at the second moment obtained based on the first perception information is also more accurate. Therefore, the method shown in Figure 5 can improve the probability of detecting the first target and the positioning accuracy. In addition, in the method shown in Figure 5, the first target may or may not have communication capabilities, so the method shown in Figure 5 is not only applicable to scenarios where the target has communication capabilities, but also to scenarios where the target does not have communication capabilities, and has a wide range of application scenarios.

[0226] Optionally, in one possible implementation of the method shown in FIG5 , the perception management device may obtain second perception information and predict the location of the first target at a second moment based on the second perception information. The second perception information may be used to indicate information about the first target perceived at a third moment before the first moment. For example, as shown in FIG6 , the above-mentioned S501 may include the following steps:

[0227] S5011: The perception management device obtains second perception information.

[0228] In one possible design, the second perception information includes second angle information or third position information. In this application, the second angle information is used to indicate the azimuth between the first target and the second perception device at a third moment. This azimuth can represent the position of the first target relative to the second perception device at the third moment. The second angle information can be used by the perception management device to predict the position of the first target at the second moment.

[0229] Exemplarily, the second angle information includes the angle between the reflected signal of the second sensing signal and the antenna array of the second sensing device. The second sensing signal is a signal used to sense the first target (such as a signal sensing the first target at the third moment), and the reflected signal of the second sensing signal is a signal after the second sensing signal reaches the first target and is reflected by the first target. It is understandable that for the single-station sensing mode, the second sensing signal is sent by the second sensing device, and the reflected signal of the second sensing signal is a signal after the second sensing signal reaches the first target and is reflected by the first target and reaches the second sensing device. For the dual-station sensing mode, the second sensing signal is sent by the fourth sensing device, and the reflected signal of the second sensing signal is a signal after the second sensing signal reaches the first target and is reflected by the first target and reaches the second sensing device. The fourth sensing device and the third sensing device are the same or different. It should be understood that the content included in the second angle information is similar to that included in the first angle information. For details, please refer to the description of the first angle information above and will not be repeated here.

[0230] In this application, the second sensing device is the same as or different from the first sensing device. It is understandable that the second sensing device is a sensing device that is currently closer to the first target, so that the second sensing device senses the first target and obtains the second sensing information.

[0231] In the present application, the third position information can be used to indicate the position of the first target at the third moment. The representation of the third position information can refer to the above introduction to the first position information and will not be repeated here. The third position information can be used by the perception management device to predict the position of the first target at the second moment. It should be understood that the position indicated by the third position information is the same as or different from the position predicted by the perception management device. In other words, after the perception management device obtains the third position information, it can determine the position indicated by the third position information as the predicted position of the first target at the second moment, or further process the third position information to obtain the above-mentioned predicted position of the first target at the second moment, such as combining the information perceived by the perception device other than the perception device that perceives the second perception information, and / or the position of the first target at a historical moment, to predict the position of the first target at the second moment, without limitation.

[0232] Optionally, the second perception information further includes at least one of the following: information at the third moment, fifth indication information, second time delay information, or second Doppler information. The above information is introduced below respectively.

[0233] In this application, the information of the third moment is used to indicate the third moment. For example, the information of the third moment includes the third moment, or includes the difference between the third moment and the reference moment, or includes information about the time domain resource where the third moment is located. For details, please refer to the description of the information of the second moment above.

[0234] In the present application, the fifth indication information is used to indicate whether the first target is detected at the third moment. For example, the fifth indication information includes one bit. When the value of the one bit is "0", it indicates that the first target is not detected at the third moment. When the value of the one bit is "1", it indicates that the first target is detected at the third moment, and vice versa.

[0235] In this application, the second delay information is used to indicate the transmission delay of the second sensing signal. For example, in a single-station sensing mode, the transmission delay of the second sensing signal is the duration between the second sensing device transmitting the second sensing signal and receiving the reflected signal of the second sensing signal. In a multi-station sensing mode, the transmission delay of the second sensing signal is the duration between the fourth sensing device transmitting the second sensing signal and the second sensing device receiving the reflected signal of the second sensing signal.

[0236] In one possible design, the second delay information includes the transmission delay of the second perception signal, or includes the time when the second perception device sends the second perception signal and the time when the reflected signal of the second perception signal is received, or includes the time when the fourth perception device sends the second perception signal and the time when the second perception device receives the reflected signal of the second perception signal.

[0237] In the present application, the second Doppler information is used to indicate the Doppler frequency shift of the second sensing signal. For example, the second Doppler information includes the Doppler frequency shift.

[0238] It can be understood that the information at the third moment can be used by the perception management device to determine the third moment, and then know that the second perception device perceives the information of the first target at the third moment. The fifth indication information can be used by the perception management device to determine whether the first target is detected at the third moment. The second delay information can be used by the perception management device to determine the transmission delay of the second perception signal, and then predict the position information of the first target at the second moment to improve the accuracy of the predicted position. The second Doppler information can be used by the perception management device to determine the Doppler frequency shift of the second perception signal, and then determine the movement speed of the first target at the third moment based on the Doppler frequency shift. Optionally, the perception management device can also determine the movement direction of the first target at the third moment based on the Doppler frequency shift. The above-mentioned movement speed and direction can be used to predict the position information of the first target at the second moment.

[0239] In a possible implementation, the second sensing device acquires the second sensing information and sends the second sensing information to the sensing management device. Correspondingly, the sensing management device receives the second sensing information.

[0240] It is understandable that in different communication scenarios, the second sensing device obtains the second sensing information in different ways. The following describes how the second sensing device obtains the first sensing information in conjunction with the aforementioned communication scenarios 31 to 35.

[0241] Method 1: The second sensing device transmits a second sensing signal at a third moment, receives a reflection signal of the second sensing signal, and determines the second sensing information based on the reflection signal. For example, the second sensing device is sensing device 202 in communication scenario 31 shown in FIG. 3A , or the second sensing device is sensing device 204 in communication scenario 32 shown in FIG. 3B .

[0242] One possible implementation method is that if the second perception device is the perception device 204 in Figure 3B, that is, the second perception device is a terminal, the second perception device can perceive the first target based on the network device to which it is connected (such as the sixth perception device) or the communication resources configured by the perception management device. For example, the sixth perception device sends information about the first time-frequency resource to the second perception device. After the second perception device receives the information about the first time-frequency resource, it perceives the first target at the third moment based on the information about the first time-frequency resource and obtains the second perception information. The information about the first time-frequency resource is used to indicate the time-frequency resource of the perception signal used to perceive the first target at the third moment. In other words, the second perception device sends the second perception signal on the time-frequency resource indicated by the information about the first time-frequency resource.

[0243] Optionally, after the second perception device obtains the second perception information, it sends the second perception information to the perception management device through the sixth perception device.

[0244] Optionally, the second sensing device obtains the second sensing information based on an instruction from the sensing management device. For example, the sensing management device sends fourth instruction information to the second sensing device. The fourth instruction information indicates a sensing target. After receiving the fourth instruction information, the second sensing device scans its sensing area and senses the first target at the third moment, thereby obtaining the second sensing information.

[0245] It can be understood that in order to cover the perception area of ​​the second perception device, the second perception device can send perception signals in different directions. When the second perception device detects that the receiving power of the reflected signal of the perception signal in a certain direction is greater than a certain threshold value, it can be determined that there is a target in that direction, and the corresponding perception information can be determined based on the reflected signal of the perception signal in that direction.

[0246] Optionally, the perception management device sends sixth indication information to the second perception device. The sixth indication information is used to indicate that the perception mode of the second perception information is a single-station perception mode or a dual-station perception mode. After receiving the sixth indication information, the second perception device can perceive the first target according to the perception mode indicated by the sixth indication information to obtain the second perception information. Alternatively, the perception management device sends the sixth indication information to the sixth perception device so that the sixth perception device indicates the perception mode of the second perception information to the second perception device, so that the second perception device perceives the first target according to the perception mode and obtains the second perception information.

[0247] Exemplarily, the sixth indication information includes 1 bit. If the value of the 1 bit is "0", the sixth indication information indicates a single-station sensing mode. If the value of the 1 bit is "1", the sixth indication information indicates a dual-station sensing mode, and vice versa.

[0248] Optionally, if the perception mode of the second perception information is a dual-station perception mode, the perception management device sends seventh indication information to the second perception device. The seventh indication information is used to indicate the device that sends the perception signal and / or the device that receives the perception signal in the dual-station perception mode. After the second perception device receives the seventh indication information, it can determine whether it sends the second perception signal or receives the reflected signal of the second perception signal based on the seventh indication information. Alternatively, the perception management device sends the seventh indication information to the sixth perception device so that the sixth perception device indicates to the second perception device whether the second perception device sends the second perception signal or receives the reflected signal of the second perception signal.

[0249] Exemplarily, if the second sensing device is a device that sends a sensing signal, the seventh indication information includes the identifier of the second sensing device. After receiving the seventh indication information, the second sensing device can determine that it has sent the second sensing signal. Alternatively, if the second sensing device is a device that receives a sensing signal, the seventh indication information includes the identifier of the second sensing device. After receiving the seventh indication information, the second sensing device can determine that it has received the second sensing signal. Alternatively, the seventh indication information includes the identifier of the device that sends the sensing signal and the identifier of the device that receives the sensing signal, and the two identifiers are arranged in the order of the identifier of the device that sends the sensing signal first and the identifier of the device that receives the sensing signal second, or the two identifiers are arranged in the order of the identifier of the device that sends the sensing signal first and the identifier of the device that receives the sensing signal second.

[0250] It can be understood that the above are merely examples of the sixth indication information and the seventh indication information. In specific applications, the sixth indication information and the seventh indication information may also indicate corresponding information in other ways, which are not limited.

[0251] The above describes the perception management device instructing the second perception device to perceive the first target at the third moment. In a specific application, in addition to the second perception device, the perception management device can also instruct other perception devices to perceive the first target at the third moment, and combine the second perception information and the perception information obtained by other perception devices (such as the fifth perception information) to predict the position of the first target at the second moment, so as to further improve the positioning accuracy. It should be understood that other perception devices can obtain perception information through method 1, the following method 2, or the multi-station perception mode, without limitation.

[0252] Method 2: The fourth sensing device sends a second sensing signal at a third moment, the second sensing device receives a reflection signal of the second sensing signal, and determines the second sensing information based on the reflection signal. For example, taking communication scenario 33 shown in FIG. 3C or communication scenario 34 shown in FIG. 3D as an example, the second sensing device is sensing device 202 and the fourth sensing device is sensing device 204, or the second sensing device is sensing device 204 and the fourth sensing device is sensing device 202. Taking communication scenario 35 shown in FIG. 3E as an example, the second sensing device is sensing device 204 and the fourth sensing device is sensing device 206, or the second sensing device is sensing device 206 and the fourth sensing device is sensing device 204.

[0253] It can be understood that, similar to the logic of method 1, if the second perception device or the fourth perception device is a terminal, the two can perceive the first target based on the communication resources configured by the network device (such as the sixth perception device) or the perception management device to which they are connected. For example, the sixth perception device sends information about the first time-frequency resource to the second perception device (or the fourth perception device). After the second perception device (or the fourth perception device) receives the information about the first time-frequency resource, it perceives the first target at the third moment based on the information about the first time-frequency resource and obtains the second perception information. In other words, the fourth perception device sends the second perception signal on the time-frequency resource indicated by the information about the first time-frequency resource, and the second perception device receives the reflected signal on the time-frequency resource indicated by the information about the first time-frequency resource.

[0254] Optionally, after the second perception device obtains the second perception information, it sends the second perception information to the perception management device through the sixth perception device.

[0255] It is understood that if the second sensing device is a terminal and the fourth sensing device is a network device, the sixth sensing device and the fourth sensing device may be the same or different. Similarly, if the fourth sensing device is a terminal and the second sensing device is a network device, the sixth sensing device and the second sensing device may be the same or different.

[0256] It can be understood that in method 2, the fourth perception device can obtain the fourth indication information in a similar manner to the second perception device to send perception signals, and / or, sixth indication information, and / or, seventh indication information in different directions.

[0257] The above describes that the perception management device instructs the second perception device and the fourth perception device to perceive the first target at the third moment using the dual-station perception mode. In a specific application, in addition to the second perception device and the fourth perception device, the perception management device can also instruct other perception devices to perceive the first target at the third moment, and combine the second perception information and the perception information obtained by other perception devices (such as the sixth perception information) to predict the position of the first target at the third moment, so as to further improve the accuracy of the predicted position. It should be understood that other perception devices can obtain perception information through the above-mentioned method 1, method 2 or multi-station perception mode without limitation.

[0258] S5012: The perception management device determines the first location information based on the second perception information at the first moment.

[0259] In a possible implementation, the perception management device determines the first location information based on the third location information included in the second perception information.

[0260] In another possible implementation, the perception management device determines the position of the first target at the third moment based on the second perception information, the position information of the second perception device, and the array orientation information of the second perception device, and determines the first position information based on the position.

[0261] For example, if the second perception information includes second angle information, the perception management device determines the position of the first target at the third moment based on the second angle information, the position information of the second perception device, and the array orientation information of the second perception device, and determines the first position information based on the position.

[0262] For another example, if the second perception information includes second angle information and second delay information, the perception management device determines the position of the first target at the third moment based on the second angle information, the second delay information, the position information of the second perception device, and the array orientation information of the second perception device, and determines the first position information based on the position.

[0263] For another example, if the second perception information includes second angle information and second Doppler information, the perception management device determines the position of the first target at the third moment based on the second angle information, the position information of the second perception device, and the array orientation information of the second perception device, determines the movement speed and movement direction of the first target at the third moment based on the second Doppler information, and determines the first position information based on the position, the movement speed, and the movement direction.

[0264] Optionally, the perception management device obtains the array orientation information of the second perception device. For example, the second perception device sends the array orientation information to the perception management device, and the perception management device receives the array orientation information, thereby obtaining the array orientation information. Alternatively, the perception management device stores the array orientation information and can obtain the array orientation information locally.

[0265] Optionally, the perception management device obtains the location information of the second perception device. For example, a positioning device (such as positioning device 205 in Figure 2) sends the location information of the second perception device to the perception management device, and the perception management device receives the location information, thereby obtaining the location information. Alternatively, the perception management device stores the location information and can obtain the location information locally.

[0266] Optionally, when determining the first location information, the perception management device may also refer to the location information of the first target at a moment before the third moment, so that the predicted location information is more accurate.

[0267] Optionally, in one possible implementation of the method shown in FIG5 , the perception management device may send the first location information to the first perception device, so that the first perception device transmits a beam using a beamforming technique based on the first location information, so that the transmitted beam has a higher transmission power in the direction of the location indicated by the first location information, thereby better perceiving the first target and obtaining more accurate first perception information. For example, as shown in FIG6 , the above-mentioned S502 may include the following steps:

[0268] S5021: The first sensing device obtains the first position information at the fourth moment.

[0269] It can be understood that the first perception device can obtain the first location information directly from the perception management device, or the first perception device can obtain the first location information from the perception management device through other perception devices, such as the fifth perception device. For example, in the above-mentioned communication scenario 31 or communication scenario 33, the first perception device obtains the first location information directly from the perception management device. In the above-mentioned communication scenario 32 or communication scenario 35, the first perception device obtains the first location information from the perception management device through the fifth perception device. In the above-mentioned communication scenario 34, the first perception device obtains the first location information directly from the perception management device, or the first perception device obtains the first location information from the perception management device through the fifth perception device. This will be explained in detail below.

[0270] Exemplarily, for the above-mentioned communication scenario 31, the first perception device is the perception device 202, the perception management device sends the first location information to the first perception device, and the first perception device receives the first location information at the fourth moment, that is, obtains the first location information.

[0271] Exemplarily, for the above-mentioned communication scenario 32, the fifth sensing device is the sensing device 202, the first sensing device is the sensing device 204, and the sensing management device sends the first location information to the fifth sensing device. After receiving the first location information, the fifth sensing device sends the first information to the first sensing device. The first information is used to determine the first location information. For example, the first information includes the first location information, or includes the angle between the position indicated by the first location information and the antenna array surface of the first sensing device. If the first information includes the first location information, the first sensing device receives the first information at the fourth moment, that is, obtains the first location information. If the first information includes the above-mentioned angle, after the first sensing device receives the first information, it determines the first location information at the fourth moment based on the first information, the position of the first sensing device, and the direction of the antenna array surface of the first sensing device.

[0272] Exemplarily, for the above-mentioned communication scenario 33, the first sensing device is sensing device 202 or sensing device 204, and the sensing management device sends the first location information to the first sensing device. The first sensing device receives the first location information at the fourth moment, i.e., the first location information is obtained. It is understandable that if the first sensing device is sensing device 202, after sensing device 202 receives the first location information, it sends the first information to sensing device 204 so that sensing device 204 can determine the first location information. Similarly, if the first sensing device is sensing device 204, after sensing device 204 receives the first location information, it sends the first information to sensing device 202 so that sensing device 202 can determine the first location information.

[0273] Exemplarily, for the above-mentioned communication scenario 34, the first sensing device is sensing device 202, the sensing management device sends the first location information to the first sensing device, and the first sensing device receives the first location information at the fourth moment, that is, the first location information is obtained. After the first sensing device obtains the first location information, it sends the first information to sensing device 204. Alternatively, the first sensing device is sensing device 204, and the fifth sensing device is sensing device 202, and the sensing management device sends the first location information to the fifth sensing device. After the fifth sensing device receives the first location information, it sends the first information to the first sensing device. If the first information includes the first location information, the first sensing device receives the first information at the fourth moment, that is, the first location information is obtained. If the first information includes the above-mentioned angle, after the first sensing device receives the first information, it determines the first location information at the fourth moment based on the first information, the position of the first sensing device, and the antenna array direction of the first sensing device.

[0274] Exemplarily, for the above-mentioned communication scenario 35, the first sensing device is sensing device 204 and sensing device 206, the fifth sensing device is sensing device 202, and the sensing management device sends the first location information to the fifth sensing device. After receiving the first location information, the fifth sensing device sends the first information to the first sensing device. If the first information includes the first location information, the first sensing device receives the first information at the fourth moment, and thus obtains the first location information. If the first information includes the above-mentioned angle, after receiving the first information, the first sensing device determines the first location information at the fourth moment based on the first information, the position of the first sensing device, and the antenna array orientation of the first sensing device.

[0275] In this application, the second moment is later than the fourth moment. For example, the relationship between the first moment, the second moment, and the fourth moment can be shown in Figure 7. As can be understood from Figure 7, the perception management device first obtains the first location information at the first moment and then sends the first location information. After the first perception device obtains the first location information at the fourth moment, it perceives the first target based on the first location information at the second moment.

[0276] In a possible implementation manner, the perception management device may send the first location information when the configuration of the perception signal used to perceive the first target changes.

[0277] Exemplarily, the perception management device sends the first location information when the beam corresponding to the perception signal used to perceive the first target is switched, or when the first target moves from one cell to another. Taking the first perception device as the perception device shown in Figure 1C as an example, when the beam corresponding to the perception signal used to perceive the first target is switched from beam 121 to beam 122, the perception management device sends the first location information to the first perception device. Alternatively, when the first target moves from one cell of the first perception device to another cell, the perception management device sends the first location information to the first perception device. Alternatively, when the first target moves from a cell of a perception device other than the first perception device to the cell of the first perception device, the perception management device sends the first location information to the first perception device.

[0278] Optionally, the first sensing device is a sensing device near the location indicated by the first location information. For example, the distance between the first sensing device and the location indicated by the first location information is less than or equal to the first value. In this way, the first target can be accurately sensed, making the obtained first sensing information more accurate.

[0279] Optionally, the perception management device sends information about the second time to the first perception device, so that the first perception device determines the second time and perceives the first target at the second time. Alternatively, the perception management device sends information about the second time to the fifth perception device, so that the fifth perception device indicates the second time to the first perception device, so that the first perception device determines the second time and perceives the first target at the second time.

[0280] Optionally, the perception management device sends a second indication message to the first perception device. The second indication message is used to indicate that the perception mode of the first perception information is a single-station perception mode or a dual-station perception mode. After receiving the second indication message, the first perception device can perceive the first target according to the perception mode indicated by the second indication message to obtain the first perception information. Alternatively, the perception management device sends the second indication message to the fifth perception device so that the fifth perception device indicates the perception mode of the first perception information to the first perception device, so that the first perception device perceives the first target according to the perception mode and obtains the first perception information.

[0281] Exemplarily, the second indication information includes 1 bit. If the value of the 1 bit is "0", the second indication information indicates a single-station sensing mode; if the value of the 1 bit is "1", the second indication information indicates a dual-station sensing mode, and vice versa.

[0282] Optionally, if the perception mode of the first perception information is a dual-station perception mode, the perception management device sends third indication information to the first perception device. The third indication information is used to indicate the device that sends the perception signal and / or the device that receives the perception signal in the dual-station perception mode. After the first perception device receives the third indication information, it can determine whether it sends the first perception signal or receives the reflected signal of the first perception signal based on the third indication information. Alternatively, the perception management device sends the third indication information to the fifth perception device so that the fifth perception device indicates to the first perception device whether the first perception device sends the first perception signal or receives the reflected signal of the first perception signal.

[0283] Exemplarily, if the first sensing device is a device that sends a sensing signal, the third indication information includes the identifier of the first sensing device. After receiving the third indication information, the first sensing device can determine that it has sent the first sensing signal. Alternatively, if the first sensing device is a device that receives a sensing signal, the third indication information includes the identifier of the first sensing device. After receiving the third indication information, the first sensing device can determine that it has received the first sensing signal. Alternatively, the third indication information includes the identifier of the device that sends the sensing signal and the identifier of the device that receives the sensing signal, and the two identifiers are arranged in the order of the identifier of the device that sends the sensing signal first and the identifier of the device that receives the sensing signal later, or the two identifiers are arranged in the order of the identifier of the device that sends the sensing signal first and the identifier of the device that receives the sensing signal later.

[0284] It can be understood that the above are merely examples of the second indication information and the third indication information. In specific applications, the second indication information and the third indication information may also indicate corresponding information in other ways without limitation.

[0285] S5022: The first sensing device sends first sensing information to the sensing management device. Correspondingly, the sensing management device receives the first sensing information from the first sensing device.

[0286] It can be understood that after the first perception device obtains the first location information, it can obtain first perception information based on the first location information and send the first perception information to the perception management device so that the perception management device can determine the position of the first target at the second moment based on the first perception information.

[0287] It is understandable that in different communication scenarios, the first perception device obtains the first perception information in different ways. The following describes the ways in which the first perception device obtains the first perception information in conjunction with the aforementioned communication scenarios 31 to 35.

[0288] Method 3: The first sensing device transmits a first sensing signal at a second moment based on the first location information, receives a reflection signal of the first sensing signal, and determines the first sensing information based on the reflection signal. For example, the first sensing device is sensing device 202 in communication scenario 31 shown in FIG. 3A , or the first sensing device is sensing device 204 in communication scenario 32 shown in FIG. 3B .

[0289] One possible implementation method is that if the first perception device is the perception device 204 in Figure 3B, that is, the first perception device is a terminal, the first perception device can perceive the first target based on the network device (such as the fifth perception device) to which it is connected or the communication resources configured by the perception management device. For example, the fifth perception device sends information about the second time-frequency resource to the first perception device. After the first perception device receives the information about the second time-frequency resource, it perceives the first target at the second moment based on the first position information and the information about the second time-frequency resource, and obtains the first perception information. The information about the second time-frequency resource is used to indicate the time-frequency resource of the perception signal used to perceive the first target at the second moment. In other words, the first perception device sends the first perception signal on the time-frequency resource indicated by the information about the second time-frequency resource.

[0290] Optionally, after the first perception device obtains the first perception information, it sends the first perception information to the perception management device through the fifth perception device.

[0291] It can be understood that in method 3, the first sensing device obtains the first position information before sending the first sensing signal, so the beamforming technology can be used to transmit a transmit beam in the direction of the position indicated by the first position information, and the first sensing signal is sent through the transmit beam to increase the transmit power of the first sensing signal, thereby increasing the receive power of the reflected signal of the first sensing signal and the receive signal-to-noise ratio of the reflected signal. Subsequently, the first sensing device uses the beamforming technology to transmit a receive beam in the direction of the position indicated by the first position information, and receives the above-mentioned reflected signal through the receive beam to increase the receive power and receive signal-to-noise ratio of the reflected signal, making the obtained first sensing information more accurate, thereby increasing the probability of detecting the first target and the positioning accuracy.

[0292] The above describes how the perception management device instructs the first perception device to perceive the first target at the second moment. In a specific application, in addition to the first perception device, the perception management device may also instruct other perception devices to perceive the first target at the second moment, and determine the position of the first target at the second moment by combining the first perception information with the perception information obtained by the other perception devices (such as third perception information) to further improve positioning accuracy. It should be understood that other perception devices can obtain perception information through method 3, the following method 4, or a multi-station perception mode, without limitation.

[0293] Method 4: The third sensing device sends a first sensing signal at the second moment based on the first location information, and the first sensing device receives a reflection signal of the first sensing signal and determines the first sensing information based on the reflection signal. For example, taking communication scenario 33 shown in FIG3C or communication scenario 34 shown in FIG3D as an example, the first sensing device is sensing device 202 and the third sensing device is sensing device 204, or the first sensing device is sensing device 204 and the third sensing device is sensing device 202. Taking communication scenario 35 shown in FIG3E as an example, the first sensing device is sensing device 204 and the third sensing device is sensing device 206, or the first sensing device is sensing device 206 and the third sensing device is sensing device 204.

[0294] It can be understood that, similar to the logic of method 3, if the first sensing device or the third sensing device is a terminal, the two can perceive the first target based on the communication resources configured by the network device (such as the fifth sensing device) or the sensing management device to which they are connected. For example, the fifth sensing device sends information about the second time-frequency resource to the first sensing device (or the third sensing device). After the first sensing device (or the third sensing device) receives the information about the second time-frequency resource, it perceives the first target at the second moment based on the first position information and the information about the second time-frequency resource, and obtains the first sensing information. In other words, the third sensing device sends the first sensing signal on the time-frequency resource indicated by the information about the second time-frequency resource, and the first sensing device receives the reflected signal on the time-frequency resource indicated by the information about the second time-frequency resource.

[0295] Optionally, after the first perception device obtains the first perception information, it sends the first perception information to the perception management device through the fifth perception device.

[0296] It is understood that if the first sensing device is a terminal and the third sensing device is a network device, the fifth sensing device and the third sensing device may be the same or different. Similarly, if the third sensing device is a terminal and the first sensing device is a network device, the fifth sensing device and the first sensing device may be the same or different.

[0297] It can be understood that in mode 4, the third sensing device obtains the first position information before sending the first sensing signal, so it can use beamforming technology to transmit a transmit beam in the direction of the position indicated by the first position information, and send the first sensing signal through the transmit beam to increase the transmit power of the first sensing signal, thereby increasing the receive power of the reflected signal of the first sensing signal and the receive signal-to-noise ratio of the reflected signal. The first sensing device obtains the first position information before receiving the reflected signal of the first sensing signal, so it can use beamforming technology to transmit a receive beam in the direction of the position indicated by the first position information, and receive the reflected signal through the receive beam to increase the receive power and receive signal-to-noise ratio of the reflected signal, thereby making the obtained first sensing information more accurate, thereby increasing the probability of detecting the first target and the positioning accuracy.

[0298] The above describes that the perception management device instructs the first perception device and the third perception device to use the dual-station perception mode to perceive the first target at the second moment. In a specific application, in addition to the first perception device and the third perception device, the perception management device can also instruct other perception devices to perceive the first target at the second moment, and combine the first perception information and the perception information obtained by the other perception devices (such as the fourth perception information) to determine the position of the first target at the second moment, so as to further improve the positioning accuracy. It should be understood that other perception devices can obtain perception information through the above-mentioned method 3, method 4 or multi-station perception mode without limitation.

[0299] It can be understood that in method 4, the third sensing device can obtain the first position information, and / or the information at the second moment, and / or the second indication information, and / or the third indication information in a similar manner to the first sensing device.

[0300] It can be understood that the actions of the perception management device, the first perception device, the second perception device, the third perception device or the fourth perception device in the above S5011-S5012 and S5021-S5022 can be executed by the processor 401 in the communication device 40 shown in Figure 4 calling the application code stored in the memory 403, and this application does not impose any restrictions on this.

[0301] It can be understood that the method shown in Figure 5 or Figure 6 can accurately locate the first target. Therefore, the method described in Figure 5 or Figure 6 can be used for vehicle tracking, drone tracking and navigation in intelligent traffic scenarios, and detection and positioning of people, animals, vehicles or drones on the road.

[0302] The above mainly introduces the solution provided by this application from the perspective of interaction between various devices. Accordingly, this application also provides a communication device, which can be the perception management device in the above method embodiment, or a device including the above perception management device, or a component that can be used for the perception management device; or, the communication device can be the perception device (such as the first perception device, the second perception device, the third perception device, the fourth perception device, the fifth perception device or the sixth perception device, etc.) in the above method embodiment, or a device including the above perception device, or a component that can be used for the perception device. It is understandable that in order to implement the above functions, the above perception management device or perception device, etc., includes hardware structures and / or software modules corresponding to the execution of each function. It should be easy for those skilled in the art to appreciate that, in combination with the units and algorithm operations of the various examples described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in hardware or in a computer software-driven hardware manner depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0303] The present application can divide the perception management device or perception device into functional modules according to the above method examples. 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 above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It is understandable that the division of modules in this application is schematic and is only a logical functional division. There may be other division methods in actual implementation.

[0304] For example, FIG8 shows a schematic diagram of the structure of a communication device 80, where the functional modules are divided in an integrated manner. Communication device 80 includes a processing module 801. Optionally, communication device 80 also includes an interface module 802. Processing module 801, also known as a processing unit, is configured to perform operations other than transceiver operations and may be, for example, a processing circuit or processor. Interface module 802, also known as an interface unit, is configured to perform transceiver operations and may be, for example, an interface circuit, a transceiver, a transceiver, or a communication interface.

[0305] In some embodiments, the communication device 80 may further include a storage module (not shown in FIG. 8 ) for storing program instructions and data.

[0306] Exemplarily, the communication device 80 is used to implement the functions of the perception management device. The communication device 80 is, for example, the perception management device described in the embodiment shown in FIG5 or the embodiment shown in FIG6.

[0307] The processing module 801 is configured to obtain first location information of a first target at a first moment. The first location information indicates the location of the first target at a second moment, where the second moment is later than the first moment. For example, the processing module 801 may be configured to execute S501.

[0308] The processing module 801 is further configured to obtain first perception information, wherein the first perception information is used to indicate information about the first target perceived at the second moment based on the first location information. For example, the processing module 801 may be configured to execute S802.

[0309] The processing module 801 is further configured to determine the position information of the first target at the second moment according to the first perception information. For example, the processing module 801 can be configured to execute S803.

[0310] In one possible implementation, the processing module 801 is specifically used to send the first location information to the first perception device through the interface module 802; the processing module 801 is also specifically used to receive the first perception information from the first perception device through the interface module 802.

[0311] In one possible implementation, the first perception information includes first angle information or second position information, the first angle information is used to indicate the azimuth between the first target and the first perception device at the second moment, and the second position information is used to indicate the position of the first target at the second moment.

[0312] In one possible implementation, the first perception information also includes at least one of the following: information at the second moment, first indication information, first delay information, or first Doppler information; wherein the first indication information is used to indicate whether the first target is detected at the second moment, the first delay information is used to indicate the transmission delay of the first perception signal, the first Doppler information is used to indicate the Doppler frequency shift of the first perception signal, and the first perception signal is a signal used to perceive the first target.

[0313] In one possible implementation, the interface module 802 is used to send second indication information to the first perception device, where the second indication information is used to indicate whether the perception mode of the first perception information is a single-station perception mode or a dual-station perception mode.

[0314] In one possible implementation, the perception mode of the first perception information is a dual-station perception mode, and the interface module 802 is also used to send third indication information to the first perception device, and the third indication information is used to indicate the device for sending the perception signal and / or the device for receiving the perception signal in the dual-station perception mode.

[0315] In a possible implementation, the interface module 802 is further configured to send information at the second moment to the first sensing device.

[0316] In one possible implementation, the processing module 801 is specifically used to obtain second perception information, where the second perception information is used to indicate information about the first target perceived at a third moment before the first moment; the processing module 801 is also specifically used to determine the first position information based on the second perception information at the first moment.

[0317] In a possible implementation, the processing module 801 is specifically configured to receive second perception information from a second perception device through the interface module 802 .
