[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202411370537.7, filed on September 27, 2024, and entitled “A Communication Method and Apparatus”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a communication method and apparatus. BACKGROUND

[0004] Wireless sensing technology can obtain the characteristics of the signal propagation space by analyzing the changes of wireless signals in the propagation process, thereby achieving the perception of the scene. Taking radar as an example, the basic principle is that the transmitter transmits a specific waveform signal, which can be transmitted to the receiver through the wireless channel. By combining the transmitted signal and the received signal, the target of interest in the wireless channel can be extracted, thereby achieving wireless sensing.

[0005] Wireless communication can be used to exchange information between the transmitting and receiving ends, and the basic principle includes that the transmitter transmits a specific waveform signal, which is received by the receiver after passing through the wireless channel. After signal processing by the receiver, the signal transmitted by the transmitter is demodulated.

[0006] From the process of transmitting signals, transmitting signals, and receiving signals, it can be seen that the processes of wireless communication and wireless sensing are very similar. Therefore, the combination of wireless communication and wireless sensing can be used to communicate between the transmitting and receiving ends while sensing the surrounding environment. Specifically, the sensing signal can be transmitted on the frequency domain resource, which can be used to carry the information exchanged between the transmitting and receiving ends, and also can be used to sense the objects in the surrounding environment.

[0007] How to feed back the sensing measurement result needs further research. SUMMARY

[0008] The present application provides a communication method and apparatus for feeding back the sensing measurement result.

[0009] In a first aspect, an embodiment of the present application provides a communication method, which can be applied to a first device. The first device can be a terminal or an access network device, or can be a device (e.g., a module, a communication module, a circuit or a chip responsible for communication functions and / or sensing functions (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core), a chip system or a processor) of a terminal or an access network device, or can be a logic node, a logic module or software capable of realizing all or part of the functions of a terminal or an access network device. For ease of description, the following describes the first device as an example. The method can include: the first device obtaining a first sensing measurement result corresponding to a sampling point in a sampling window, the sampling window being associated with a region of interest; and the first device sending first information. The first information indicates the first sensing measurement result and a sensing measurement result corresponding to one or more sampling points outside the sampling window, or the first information indicates a second sensing measurement result obtained by processing the first sensing measurement result based on a sensing measurement result corresponding to part or all of the one or more sampling points.

[0010] Through the method, the first device can send the first information to a second device. If the first information indicates the first sensing measurement result and the sensing measurement result corresponding to the one or more sampling points outside the sampling window, the second device can process the first sensing measurement result based on the sensing measurement result corresponding to the one or more sampling points, so as to reduce or avoid the influence of interference caused by the sensing measurement result corresponding to the sampling point outside the sampling window on the sensing measurement result corresponding to the sampling point in the sampling window. If the first information indicates the second sensing measurement result obtained by processing the first sensing measurement result based on the sensing measurement result corresponding to part or all of the one or more sampling points outside the sampling window, the influence of interference caused by the sensing measurement result corresponding to the sampling point outside the sampling window on the sensing measurement result corresponding to the sampling point in the sampling window can be reduced or avoided.

[0011] In a second aspect, an embodiment of the present application provides a communication method, which can be applied to a second device. The second device can be a sensing management function or a device comprising a sensing management function. The device comprising a sensing management function can be a terminal or an access network device, or a module, a communication module, a circuit or a chip (such as a modem chip, or a SoC chip or a SIP chip comprising a modem core) responsible for communication functions and / or sensing functions in the terminal or the access network device, or a chip system or a processor, or a logic node, a logic module or software capable of realizing all or part of the functions of the terminal or the access network device, or a device independent of the terminal or the access network device. For ease of description, the following describes the second device as an example. The method can comprise: receiving, by the second device, first information. The first information indicates: first sensing measurement results corresponding to sampling points in a sampling window, and sensing measurement results corresponding to one or more sampling points outside the sampling window; or the first information indicates second sensing measurement results obtained by processing the first sensing measurement results according to sensing measurement results corresponding to part or all of the one or more sampling points. The sampling window is associated with a region of interest. The second device performs sensing processing according to the first information.

[0012] By the method, the second device can receive the first information from the first device. If the first information indicates the first sensing measurement results and the sensing measurement results corresponding to the one or more sampling points outside the sampling window, the second device can process the first sensing measurement results according to the sensing measurement results corresponding to the one or more sampling points, so as to reduce or avoid the influence of interference caused by the sensing measurement results corresponding to the sampling points outside the sampling window on the sensing measurement results corresponding to the sampling points in the sampling window. If the first information indicates the second sensing measurement results obtained by processing the first sensing measurement results according to the sensing measurement results corresponding to part or all of the one or more sampling points outside the sampling window, the influence of interference caused by the sensing measurement results corresponding to the sampling points outside the sampling window on the sensing measurement results corresponding to the sampling points in the sampling window can be reduced or avoided.

[0013] Based on the first aspect or the second aspect, in a possible design, the region of interest is a region where an object to be measured is located; and / or, the region of interest is a region to be measured. This design can be used to accurately determine the region of interest.

[0014] Based on the first aspect or the second aspect, in a possible design, the one or more sampling points comprise a first sampling point, which can satisfy at least one of the following conditions:

[0015] The amplitude of the main lobe corresponding to the first sampling point is greater than or equal to a first amplitude threshold.

[0016] the amplitude of the sidelobe corresponding to the first sampling point is greater than or equal to a second amplitude threshold;

[0017] the interval from the first sampling point to the sampling window is less than or equal to an interval threshold;

[0018] the absolute value of the difference between a first transmission delay and a second transmission delay is less than or equal to a delay threshold, the first transmission delay being the transmission delay of the perception signal corresponding to the first sampling point, and the second transmission delay being the transmission delay of the perception signal corresponding to a sampling point located at the edge of the sampling window; or

[0019] the absolute value of the difference between a first transmission distance and a second transmission distance is less than or equal to a distance threshold, the first transmission distance being the transmission distance of the perception signal corresponding to the first sampling point, and the second transmission distance being the transmission distance of the perception signal corresponding to a sampling point located at the edge of the sampling window.

[0020] Through the design, the first device can accurately select the one or more sampling points outside the sampling window. In addition, in the design, the first device can feed back the perception measurement result for the sampling point satisfying the above conditions, and can not feed back the perception measurement result corresponding to all sampling points outside the sampling window, so that the overhead of feeding back the perception measurement result can be reduced.

[0021] Based on the first aspect or the second aspect, in a possible design, the method further includes: the second device sending second information; and correspondingly, the first device receiving the second information, the second information indicating at least one of the following: the first amplitude threshold, the second amplitude threshold, the interval threshold, the delay threshold, or the distance threshold. In this way, the first device can accurately determine at least one of the above thresholds according to the second information, so that the one or more sampling points can be accurately selected according to at least one of the above thresholds.

[0022] Based on the first aspect or the second aspect, in a possible design, the method further includes: the second device sending third information; and correspondingly, the second device receiving the third information. The third information indicates a mode of feeding back the perception measurement result. In a case where the third information indicates that the mode of feeding back the perception measurement result is a first mode, the first information indicates the first perception measurement result and the perception measurement result corresponding to the one or more sampling points; and in a case where the third information indicates that the mode of feeding back the perception measurement result is a second mode, the first information indicates the second perception measurement result. In this way, the first device can accurately determine the mode of feeding back the perception measurement result according to the third information.

[0023] In a possible design based on the first aspect or the second aspect, in the case that the first information indicates the first sensing measurement result and the sensing measurement result corresponding to the one or more sampling points outside the sampling window, the first information further indicates channel impulse response information of the point target. In this way, in the case that the channel impulse response information corresponding to the sampling point in the sampling window is multi-target channel impulse response information, the second device can decompose the channel impulse response information corresponding to the sampling point in the sampling window according to the channel impulse response information of the point target and the channel impulse response information corresponding to the one or more sampling points outside the sampling window, to obtain the channel impulse response information of the point target corresponding to the sampling point.

[0024] In a possible design based on the first aspect or the second aspect, the first information indicates the channel impulse response information of the point target, including at least one of the following:

[0025] 1. The first information includes the channel impulse response information of the actual point target. In this way, the second device can accurately determine the channel impulse response information of the actual point target according to the first information. In addition, in this design, the second device does not need to determine the channel impulse response information of the actual point target through additional calculation, thereby reducing the complexity of the second device.

[0026] 2. The first information indicates a difference between the channel impulse response information of the actual point target and the channel impulse response information of the ideal point target, and the difference is used to determine the channel impulse response information of the actual point target. In this way, the second device can accurately determine the channel impulse response information of the actual point target according to the first information. In addition, in this design, the first information can indicate the difference between the channel impulse response information of the actual point target and the channel impulse response information of the ideal point target, which can reduce signaling overhead compared with indicating the channel impulse response information of the actual point target.

[0027] 3. The first information indicates the channel impulse response information of the ideal point target. In this way, the second device can accurately determine the channel impulse response information of the actual point target according to the first information. In addition, in this design, the first information can indicate the channel impulse response information of the ideal point target, which can reduce signaling overhead compared with indicating the channel impulse response information of the actual point target.

[0028] In a possible design based on the first aspect or the second aspect, the method further includes: the second device sends fourth information; and correspondingly, the first device receives the fourth information, and the fourth information indicates a mode of feeding back the channel impulse response information of the point target. Through this design, the first device can accurately determine the mode of feeding back the channel impulse response information of the point target according to the fourth information.

[0029] In a possible design based on the first aspect or the second aspect, in a case where the first information indicates the second perception measurement result, the first information further indicates that the second perception measurement result is obtained by processing the perception measurement result corresponding to part or all of the one or more sampling points. In this way, the second device can accurately determine that the second perception measurement result is a processed result according to the first information.

[0030] In a possible design based on the first aspect or the second aspect, the method further includes: the first device sending capability information; and correspondingly, the second device receiving the capability information. The capability information indicates whether the first device has at least one of the following capabilities: a sidelobe cancellation capability, a capability of feeding back the perception measurement result corresponding to a sampling point outside the sampling window, or a capability of feeding back the channel impulse response information of the target. The first device can be the first device or a device in which the first device is located. With this design, the second device can accurately determine the capability of the first device according to the capability information, and accordingly, can configure a feedback manner of the perception measurement result for the first device according to the capability of the first device.

[0031] In a possible design based on the first aspect or the second aspect, the method further includes: the first device sending fifth information; and correspondingly, the second device receiving the fifth information. The fifth information indicates the third perception measurement result, and the third perception measurement result is the perception measurement result corresponding to a sampling point in the sampling window, and the time corresponding to the third perception measurement result is different from the time corresponding to the first perception measurement result. With this design, for the perception measurement result corresponding to a sampling point in the sampling window at a part of time, the first device can send only the perception measurement result corresponding to the sampling point in the sampling window to the second device, and accordingly, the transmission overhead of the perception measurement result can be reduced.

[0032] In a possible design based on the first aspect or the second aspect, in a case where the first condition is met, the first device sends the first information; and correspondingly, the second device receives the first information. The first condition includes at least one of the following: a time for periodically sending the perception measurement result arrives; or a change of the perception measurement result corresponding to one or more sampling points is greater than or equal to a first threshold. With this design, the first device sends the first information for indicating the perception measurement result only in a case where the first condition is met. Compared with always sending the perception measurement result, this manner can reduce the transmission overhead of the perception measurement result.

[0033] In a third aspect, the present disclosure provides a communication apparatus. The communication apparatus can be a terminal or an access network device, or a module, a communication module, a circuit or a chip (e.g., a modem chip, or a SoC chip or a SIP chip including a modem core) responsible for communication functions and / or sensing functions in a terminal or an access network device, or a chip system or a processor, or a logic node, a logic module or software capable of implementing all or part of the functions of a terminal or an access network device, or a sensing management function or a device including a sensing management function.

[0059] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings. The technical solutions in the embodiments of the present application can be applied to various communication systems, such as a wireless local area network (WLAN), a wireless fidelity (Wi-Fi or WiFi) system, a 4th generation (4G) mobile communication system (such as a long term evolution (LTE) system), a 5th generation (5G) mobile communication system (such as a new radio (NR) system), or a future communication system. The method provided by the present application can be applied to a terrestrial network communication system or a non-terrestrial network (NTN) communication system. The NTN communication system may, for example, be a satellite communication system, or may include a drone, a high altitude platform station (HAPS), and other aerial access network devices, which are not limited by the present application.

[0060] Various aspects, embodiments or features described herein can be presented in terms of systems that can include a number of devices, components, modules, and the like. It should be appreciated that various systems can include additional devices, components, modules, etc. and / or can not include all of the devices, components, modules etc. discussed in connection with the figures. Additionally, a combination of these approaches can be used.

[0061] FIG. 1A illustrates a schematic diagram of a communication system according to an embodiment of the present application. As shown in FIG. 1A, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system can also include an Internet 300.

[0062] The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1A, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1A, collectively referred to as 120). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1A), etc., can also be included in the RAN 100. The terminals 120 are connected to the RAN nodes 110 in a wireless manner. The RAN nodes 110 are connected to the core network 200 in a wireless or wired manner. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0063] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, such as a 4G, 5G mobile communication system, or a future evolution system. The RAN 100 can also be an open RAN (ORAN or O-RAN), a cloud radio access network (CRAN), or a WiFi system. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0064] The RAN nodes 110, which can also be referred to as RAN entities or access nodes, etc., form part of the communication system and are configured to facilitate wireless access for terminals. The RAN nodes 110 in the communication system can be of the same type or of different types. In some scenarios, the roles of the RAN nodes 110 and the terminals 120 are relative, e.g., the network element 120i in Figure 1A can be a helicopter or a drone, which can be configured to move as a mobile base station. For a terminal 120j accessing the RAN 100 via the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b in Figure 1A can be understood as communication apparatuses with base station functionalities, and the network elements 120a-120j can be understood as communication apparatuses with terminal functionalities.

[0065] The RAN nodes can also be referred to as access network devices. In the following, the access network devices are used for description, unless specifically stated otherwise.

[0066] The access network devices can be devices or modules located at the network side of the above-mentioned communication system and having corresponding communication functions. The access network devices usually have communication modules, circuits or chips configured to perform corresponding communication functions. The access network devices also have programs or instructions configured to perform corresponding communication functions and the corresponding programs or instructions.

[0067] In a possible scenario, the access network device can be a base station (BS), an evolved NodeB (eNodeB), a transmission point (TP), an access point (AP), a transmission reception point (TRP), a mobile switching center, a next generation NodeB (gNB), a next generation NodeB in a future communication system, or an access node in a WiFi system, etc. The access network device can be a macro base station (such as 110a in FIG. 1A), a micro base station or an indoor station (such as 110b in FIG. 1A), a relay node or a donor node, a wireless controller in a CRAN scenario, a satellite, a drone, a balloon or an airplane, etc. Optionally, the access network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU). All or part of the functions of the access network device in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0068] In another possible scenario, multiple access network devices cooperate to assist a terminal to implement wireless access, and different access network devices respectively implement part of the functions of a base station. For example, the access network device can be a central unit (CU) or a control unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU) or a remote radio head (RRH).

[0069] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as an open CU (O-CU), the DU can also be referred to as an open DU (O-DU), the CU-CP can also be referred to as an open CU-CP (O-CU-CP), the CU-UP can also be referred to as an open CU-UP (O-CU-UP), and the RU can also be referred to as an open RU (O-RU). Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0070] For ease of description, the concepts of "access network device" and "station" will be mentioned in this application. The access network device can be understood as the general term of all devices (including stations) on the access network side, for example, one or more stations can be collectively referred to as an access network device. The station can refer to a transmission node that is specifically located at a physical location. In other words, the access network device conceptually includes the station.

[0071] The terminal can be a device or module with corresponding communication functions for accessing the above communication system. The terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, a wireless terminal device, a subscriber unit, a subscriber station, a mobile station, a remote station, a user terminal device, a user agent, or a user device, etc. The terminal is usually provided with a communication module, circuit or chip for executing corresponding communication functions. The terminal can also be configured with programs or instructions for executing corresponding communication functions.

[0072] The terminal can be widely applied to various scenarios, for example, device-to-device (D2D), V2X communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. Among them, the wearable device can also be called a wearable smart device or a smart wearable device, etc., which is a general term of devices that can be worn by applying wearable technology to the intelligent design of daily wear. The terminal applied to the vehicle can be called a vehicle terminal device, for example, a transportation vehicle with wireless communication function, a communication module or an on-board unit (OBU).

[0073] For example, the terminal can include a mobile phone (or called "cellular" phone), a computer with mobile terminal device, or a portable, pocket-sized, handheld, computer-embedded mobile device, etc. For example, the terminal can be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. The terminal can also include a limited device, for example, a device with limited power consumption, or a device with limited storage capacity, or a device with limited computing capacity, etc. For example, the terminal can be a bar code, a radio frequency identification (RFID), a sensor, a global positioning system (GPS), or a laser scanner, etc. The embodiments of the present application do not limit the device form of the terminal.

[0074] In this application, the core network device refers to a device in the core network that provides service support for the terminal. For example, in the case of CN 200 as the core network in the future communication system, or the 5G core network, or the evolved 5G core network, some examples of the core network device are: access and mobility management function (AMF) entity, session management function (SMF) entity, user plane function (UPF) entity, policy control function (PCF) entity, location management function (LMF) entity, and the like, which are not listed one by one here. Among them, the AMF entity can be responsible for access management and mobility management of the terminal; the SMF entity can be responsible for session management, such as session establishment of the user, etc.; the UPF entity can be a functional entity of the user plane, mainly responsible for connecting external networks; the LMF entity can be responsible for managing the location of the terminal. For another example, in the case of CN 200 as the 4G core network, some examples of the core network device are: mobility management entity (MME) entity, home subscriber server (HSS) entity, serving gateway (S-GW) entity, policy and charging rules function (PCRF) entity, public data network gateway (PDN gateway, P-GW) entity, and the like, which are not listed one by one here. It should be noted that the entity in this application can also be referred to as a network element or a functional entity, for example, the AMF entity can also be referred to as an AMF network element or an AMF functional entity, for another example, the SMF entity can also be referred to as an SMF network element or an SMF functional entity, and for another example, the LMF entity can also be referred to as an LMF network element or an LMF functional entity. The above-mentioned core network device can work independently, or can be combined together to realize certain control functions, such as: AMF, SMF and PCF can be combined together as a core network device.

[0075] FIG. 1B illustrates another communication system provided by the embodiments of the present application. As shown in FIG. 1B, the communication system includes: a terminal, an access network device and a core network device.

[0076] The specific content of the terminal, the access network device and the core network device can refer to the description of the terminal, the access network device and the core network device in the description of the communication system shown in FIG. 1A respectively, and the repeated parts will not be described herein. The following describes the part entities included in the communication system.

[0077] The network exposure function (NEF) entity, which can also be referred to as an NEF network element or an NEF functional entity. The NEF entity can be located between the core network and a third-party application (or referred to as a core network external application or an external application) functional entity, and the third-party application needs to access the data inside the core network through the NEF entity. The NEF entity can open an interface to the third-party application in a secure manner, thereby ensuring the security of the third-party application to the 3GPP network.

[0080] The AF can refer to various services of the application layer. The AF can be an application inside the operator, for example, a voice over LTE (VoLTE) AF (for example, a VoLTE application server (AS) of 4G); or the AF can be a third-party AF, for example, a video server or a game server and the like.

[0083] A sensing reference unit (SRU) can be located at a known location, used to perform sensing measurements (e.g., one or more of measuring reference signal time difference (RSTD), reference signal receiving power (RSRP), or terminal received transmission time difference (UE Rx-Tx Time Difference)), and report the measurement results to a sensing server. In addition, the SRU can send a sensing reference signal, enabling an access network device to measure the sensing reference signal sent from the SRU located at a fixed location, and report the uplink sensing measurement results (one or more of relative time of arrival (RTOA), uplink angle of arrival (UL-AOA), or access network device received transmission time difference (gNB Rx-Tx Time Difference)). The sensing server can compare the measurement results of the SRU with the expected measurement results at the location of the SRU, and derive correction terms for other objects near the SRU. The downlink and / or uplink sensing measurement results of the other objects can be corrected according to the correction terms. From the perspective of the sensing server, the SRU can be regarded as a terminal with a known location.

[0084] A sensing management function can be used to manage sensing. The sensing management function can be located in a terminal or an access network device, or the sensing management function can be a network element independent of the terminal or the access network device.

The sensing service client can be an entity within a public land mobile network (PLMN), such as an operation and management (O&M) tool, or an entity outside the PLMN, such as a third-party positioning server deployed by a non-operator. The sensing service client initiates a sensing request carrying parameters such as QoS to request location information of one or more sensing targets.

[0087] The communication system and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0088] The related terms involved in the embodiments of the present application will be explained first. It should be noted that these explanations are used to make the embodiments of the present application easier to understand, and should not be regarded as a limitation on the scope of protection required by the present application.

[0089] I. ISAC:

[0090] The communication-sensing integrated technology is considered as one of the key technologies for expanding the service capabilities of mobile communication networks. The core idea of the communication-sensing integrated technology is to add sensing capabilities to mobile communication networks to build the ability to detect, track, and image targets, so that the two capabilities of communication and sensing can coexist in harmony and benefit each other in one network. Please refer to FIG. 2, which is a schematic diagram of a communication-sensing integrated scenario. In FIG. 2, the solid lines represent communication, and the dashed lines represent sensing as an example. As shown in FIG. 2, the access network device can sense other objects through self-transmission and self-reception, or can sense other objects while communicating with the terminal. In FIG. 2, the terminal is an example of a smartphone, and the sensing targets are an unmanned aerial vehicle, a pedestrian, and a vehicle.

[0091] The perception technology can be generally divided into two modes: mono-static perception and bi-static perception. In the mono-static perception mode, the transmitting device and the receiving device of the echo signal of the perception signal are the same device. In other words, in the mono-static perception mode, the transmitting device transmits the perception signal and receives the echo signal of the perception signal after the action (for example, reflection, diffraction or scattering) of the perception target. Therefore, the mono-static perception mode can also be called self-transmitting and self-receiving mode, without limitation. In the bi-static perception mode, the transmitting device and the receiving device of the echo signal of the perception signal are different devices. In other words, the perception station A transmits the perception signal, and the perception station B receives the echo signal of the perception signal after the action of the perception target.

[0092] FIG. 3 exemplarily shows a schematic diagram of a perception scene to which the embodiments of the present application are applicable. Eight perception scenes to which the embodiments of the present application are applicable are provided in FIG. 3, which are respectively: a self-transmitting and self-receiving scene of the access network device A, i.e., a scene in which the access network device A transmits the perception signal and receives the echo signal, as shown in (1) of FIG. 3; a self-transmitting and self-receiving scene of the terminal A, i.e., a scene in which the terminal A transmits the perception signal and receives the echo signal, as shown in (2) of FIG. 3; a scene in which the access network device A transmits the perception signal and the access network device B receives the echo signal, as shown in (3) of FIG. 3; a scene in which the terminal A transmits the perception signal and the terminal B receives the echo signal, as shown in (4) of FIG. 3; a scene in which the access network device A transmits the perception signal and the terminal A receives the echo signal, as shown in (5) of FIG. 3; a scene in which the terminal A transmits the perception signal and the access network device A receives the echo signal, as shown in (6) of FIG. 3; a scene in which the access network device A transmits the perception signal and the access network device B receives the echo signal under the control of the access network device C, as shown in (7) of FIG. 3; and a scene in which the terminal A transmits the perception signal and the terminal B receives the echo signal under the control of the access network device A, as shown in (8) of FIG. 3. In FIG. 3, the perception target is taken as a vehicle, and the terminal is taken as a smart phone as an example.

[0093] Optionally, the scenes shown in FIG. 3 can include one or more regions of interest, and one region of interest is taken as an example for illustration in the figure, without limitation. The perception target can be located in the region of interest. In the present application, the region of interest can have multiple possible English translations, for example, region of interest (ROI), area of interest (AOI), or field of interest (FOI).

[0094] Optionally, in the sensing scenario to which the embodiments of the present application are applicable, there can be one or more transmitting devices for transmitting the sensing signal, and one or more receiving devices for receiving the echo signal of the sensing signal. FIG. 3 illustrates one transmitting device and one receiving device by way of example, without limitation.

[0095] When there are multiple transmitting devices and one receiving device, the sensing scenario can be referred to as a multi-transmitting-single-receiving scenario. For example, sensing station A and sensing node C transmit sensing signals respectively, and the echo signal of the sensing signals resulting from the action of the sensing target is received by sensing station B. For another example, sensing station A and sensing node B transmit sensing signals respectively, and the echo signal of the sensing signals resulting from the action of the sensing target is received by sensing station B.

[0096] When there is one transmitting device and multiple receiving devices, the scenario can be referred to as a single-transmitting-multi-receiving scenario. For example, sensing station A transmits a sensing signal, and the echo signal of the sensing signal resulting from the action of the sensing target is received by sensing station B and sensing node C. For another example, sensing station A transmits a sensing signal, and the echo signal of the sensing signal resulting from the action of the sensing target is received by sensing station A and sensing node B.

[0097] The sensing target can also be referred to as a target, a detected target, a sensed object, a detected object, or a sensed device, without limitation. The sensing target can be various tangible objects in the environment that can reflect, diffract, or scatter electromagnetic waves. For example, the sensing target can be a static object such as a mountain, a forest, or a building. For another example, the sensing target can also be a movable object such as a vehicle, a drone, a pedestrian, or a terminal. The embodiments of the present application do not limit the specific implementation form of the sensing target.

[0098] The sensing measurement result can also be referred to as a sensing result, a detected result, a detected result, a detected data, or a detected data, without limitation. The sensing measurement result can be a result obtained by processing the echo signal by the receiving device. For example, the sensing measurement result can include at least one of the following: the position of the sensing target, the speed of the sensing target, the distance from the sensing target to the receiving device, the distance from the sensing target to the transmitting device, the direction of the sensing target, the angle of the sensing target, the intensity of the echo signal from the sensing target, and the like.

[0099] II. Sensing signal

[0100] In the present application, the sensing signal can include a reference signal and / or a communication signal other than the reference signal.

[0101] Among them, the reference signal is also called pilot signal. In a communication system, it is necessary to estimate the uplink channel or the downlink channel in order to send and receive data, obtain system synchronization and feedback channel information. Channel estimation refers to the process of reconstructing or recovering the received signal in order to compensate for signal distortion caused by channel fading and noise-induced fading. It uses the reference signal known by the transmitter and the receiver to determine the time domain and frequency domain variation of the channel. The above-mentioned reference signal is also called reference signal, which is distributed in one or more resource elements (REs) in the time-frequency two-dimensional space within the orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol, and has a known amplitude and phase.

[0102] For example, the reference signal can include uplink reference signals and downlink reference signals. The uplink reference signal can include but is not limited to at least one of the following: sounding reference signal (SRS), uplink demodulation reference signal (DMRS), uplink phase noise tracking signal (PTRS), or uplink positioning signal (uplink positioning RS), etc. The downlink reference signal can include but is not limited to at least one of the following: positioning reference signal (PRS), downlink DMRS, PTRS, channel state information reference signal (CSI-RS), or cell reference signal (CRS), etc.

[0103] It should be understood that the reference signals listed above are only examples and should not constitute any limitation on the present application. The present application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0104] III. Positioning method in cellular network

[0105] Positioning methods in a cellular network can include an uplink time difference of arrival (UL-TDOA) positioning method, a downlink time difference of arrival (DL-TDOA) positioning method, and a multi-round trip time (Multi-RTT) positioning method. This is described below respectively.

[0106] (1) UL-TDOA positioning method:

[0107] The UL-TDOA positioning method can be based on the time of arrival (TOA) of an uplink reference signal. Optionally, in the UL-TDOA positioning method, a terminal can send an uplink reference signal (e.g., SRS), and correspondingly, multiple access network devices can respectively receive the uplink reference signal. Each of the multiple access network devices can send the time of arrival (TOA) information of receiving the uplink reference signal to the LMF. The LMF can determine the position of the terminal according to the time difference of arrival (TDOA) between the access network devices and the positions of the multiple access network devices.

[0108] For example, as shown in (1) of FIG. 4A, the time when the uplink reference signal arrives at the base station 1 is T1, and the time when the uplink reference signal arrives at the base station 2 is T2, so the distance difference R21 between the distance R1 from the target UE to the base station 1 and the distance R2 from the target UE to the base station 2 is R21 = R2 - R1 = (T2 - T1) * c, c is the speed of light. Similarly, the time when the uplink reference signal arrives at the base station 1 is T1, and the time when the uplink reference signal arrives at the base station 3 is T3, so the distance difference R31 between the distance R1 from the target UE to the base station 1 and the distance R3 from the target UE to the base station 3 is R31 = R3 - R1 = (T3 - T1) * c. Then, the target UE is located on the hyperbola 1 with the base station 1 and the base station 2 as the foci, and the distance difference between the two foci is constant R21, and is also located on the hyperbola 2 with the base station 1 and the base station 3 as the foci, and the distance difference between the two foci is constant R31. That is, the target UE is located at the intersection of the hyperbola 1 and the hyperbola 2.

[0109] (2) DL-TDOA positioning method:

[0110] The DL-TDOA positioning method can be based on the time of arrival of downlink reference signals. For example, in the DL-TDOA positioning method, multiple access network devices can respectively send downlink reference signals (e.g., PRSs), and correspondingly, a terminal can respectively receive the downlink reference signals from the multiple access network devices. The terminal performs a downlink reference signal time difference (DL RSTD) measurement on the downlink reference signal from each access network device, and reports the DL RSTD measurement information to the LMF. The LMF can determine the position of the terminal according to the DL RSTD measurement information and the positions of the multiple access network devices.

[0111] For example, as shown in (2) of FIG. 4A, the time at which the downlink reference signal of base station 1 arrives at the target UE is T1, and the time at which the downlink reference signal of base station 2 arrives at the target UE is T2. Therefore, the distance difference R21 between the distance R1 from the target UE to base station 1 and the distance R2 from the target UE to base station 2 is R21 = R2 - R1 = (T2 - T1) * c, where c is the speed of light. Similarly, the time at which the downlink reference signal of base station 1 arrives at the target UE is T1, and the time at which the downlink reference signal of base station 3 arrives at the target UE is T3. Therefore, the distance difference R31 between the distance R1 from the target UE to base station 1 and the distance R3 from the target UE to base station 3 is R31 = R3 - R1 = (T3 - T1) * c. Then, the target UE is located on the hyperbola 1 with base station 1 and base station 2 as foci and with the distance difference between the two foci being R21, and the target UE is also located on the hyperbola 2 with base station 1 and base station 3 as foci and with the distance difference between the two foci being R31. That is, the target UE is located at the intersection of the hyperbola 1 and the hyperbola 2.

[0112] (3) Multi-RTT positioning method:

[0113] The Multi-RTT positioning method can use the relative distances between the terminal and multiple access network devices for positioning. In this method, the terminal can send an uplink reference signal (e.g., SRS), and multiple access network devices can respectively send downlink reference signals (e.g., PRSs). The uplink reference signal and the downlink reference signal can be used to determine the RTT between the terminal and each of the multiple access network devices. The LMF can determine the distance between the terminal and each of the multiple access network devices according to the RTT between the terminal and each of the multiple access network devices, and thus can determine the position of the terminal.

[0114] The following takes base station 1 as an example to explain that "the uplink reference signal and the downlink reference signal can be used to determine the RTT between the terminal and each of the multiple access network devices".

[0115] As shown in FIG. 4B, the terminal transmits the uplink reference signal at time T4, and the base station 1 receives the uplink reference signal at time T5. The base station 1 transmits the downlink reference signal at time T6, and the terminal receives the downlink reference signal at time T7. The RTT of the signals between the terminal and the base station 1 is (T7-T4)-(T6-T5).

[0116] As shown in FIG. 4C, the target UE is at the intersection of the sphere 1, the sphere 2 and the sphere 3. The sphere 1 is a sphere with the base station 1 as the center and R1 as the radius. The sphere 2 is a sphere with the base station 2 as the center and R2 as the radius. The sphere 3 is a sphere with the base station 3 as the center and R3 as the radius.

[0117] Optionally, in the above positioning method, the plurality of access network devices can be three or more access network devices.

[0118] Four, sample point:

[0119] The sample point can be a discrete data point obtained when a continuous signal (such as a channel impulse response (CIR)) is sampled. The sample point data can include the position corresponding to the sample point and the value of the sample point at the position. In this application, the sample point can also have other names, such as tap, time sample point, sampling node or perception sample point, as long as it has the same meaning and is not limited.

[0120] Five, perception measurement result:

[0121] In this application, the perception measurement result can include at least one of the following: channel impulse response information, information of the perception target, or indication information of the sample point corresponding to the perception measurement result. This will be described below.

[0122] 1. Channel impulse response information:

[0123] Optionally, the channel impulse response information includes at least one of the following: in-phase component (I component) information and quadrature-phase component (Q component) information of the channel impulse response; or amplitude information and phase information of the channel impulse response. The channel impulse response information can be used to determine the modulation signal corresponding to the sample point.

[0124] In some examples, the channel impulse response information includes I component information and Q component information of the channel impulse response. For example, there are three sampling points, which are sampling point #1 to sampling point #3. The sensing measurement result can include: I component information and Q component information of the channel impulse response corresponding to the sampling point #1; I component information and Q component information of the channel impulse response corresponding to the sampling point #2; I component information and Q component information of the channel impulse response corresponding to the sampling point #3.

[0125] In other examples, the channel impulse response information includes amplitude information and phase information of the channel impulse response. For example, there are three sampling points, which are sampling point #1 to sampling point #3. The sensing measurement result can include: amplitude information and phase information of the channel impulse response corresponding to the sampling point #1; amplitude information and phase information of the channel impulse response corresponding to the sampling point #2; amplitude information and phase information of the channel impulse response corresponding to the sampling point #3.

[0126] 2. Information of the sensing target:

[0127] For example, the information of the sensing target can include at least one of: position information of the sensing target, speed information of the sensing target, direction information of the sensing target, angle information of the sensing target, intensity information of the echo signal of the sensing target, distance information of the sensing target to the receiving device, and distance information of the sensing target to the sending device.

[0128] Optionally, the information of the sensing target can be obtained by processing the channel impulse response information, and the specific processing manner is not limited in the application.

[0129] 3. Indication information of the sampling point corresponding to the sensing measurement result:

[0130] For example, the indication information of the sampling point corresponding to the sensing measurement result can be a time stamp of the sampling point or an index of the sampling point. For example, there are three sampling points, which are sampling point #1 to sampling point #3. The sensing measurement result can include: an index of the sampling point #1, an index of the sampling point #2, and an index of the sampling point #3.

[0131] In some examples, the sensing measurement result can include: the channel impulse response information, the information of the sensing target, and the indication information of the sampling point corresponding to the sensing measurement result.

[0132] In other examples, the sensing measurement result can include: the channel impulse response information, and the indication information of the sampling point corresponding to the sensing measurement result.

[0133] Six, sensing service:

[0134] In this application, the perception service can be a service with certain service requirements. Exemplarily, the perception service can include at least one of the following: static environment reconstruction, dynamic target detection, dynamic vehicle target detection, target tracking, target identification, etc.

[0135] Optionally, the perception service can be replaced by (or understood as) a perception corresponding application type or a perception quality of service (QoS), etc.

[0136] Seven, in this application, "indicate" or "for indicating" can include explicit indication (or direct indication) and implicit indication (or indirect indication). When describing that a certain information is used to indicate A, it can include that the information explicitly indicates A or implicitly indicates A, and does not mean that A must be carried in the information.

[0137] The indication mode involved in the embodiments of this application should be understood as covering various methods that can enable the to-be-indicated party to know the to-be-indicated information. The to-be-indicated information can be sent as a whole, or can be sent separately in multiple sub-information, and the sending period and / or sending occasion of the sub-information can be the same or different, which is not limited.

[0138] The "information" in the embodiments of this application can be explicitly indicated, that is, directly indicated through signaling, or obtained according to the parameters indicated by the signaling, in combination with other rules or in combination with other parameters or through derivation. It can also be implicitly indicated, that is, obtained according to rules or relationships, or according to other parameters, or through derivation. It is not limited.

[0139] Eight, in this application, the communication between different devices can mean direct communication between different devices (that is, without the need for other devices to transfer or forward), or can mean communication between different devices through other devices (that is, with the need for other devices to transfer or forward), or can mean that a functional unit inside a device communicates with other devices through another functional unit. Exemplarily, "sending information to a (terminal)" can be understood as that the destination of the information is the terminal, which can include directly or indirectly sending information to the terminal. "Receiving information from a (terminal)" can be understood as that the source of the information is the terminal, which can include directly or indirectly receiving information from the terminal. The information can be processed as necessary between the source and the destination of the information, such as format conversion, digital-to-analog conversion, amplification, filtering, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly, which will not be repeated here.

[0140] Nine, in this application, the words "exemplarily", "such as", "for example" and "examples of" are used to represent examples, illustrations or descriptions, and are not used to limit the protection scope of this application. It should be understood that the examples in this application can also be implemented in other ways.

[0141] Ten, in this application, any two of the program, instruction and code can be replaced with each other.

[0142] Eleven, in this application, “greater than or equal to” and “greater than” can be replaced with each other, for example, “A is greater than threshold 1” and “A is greater than or equal to threshold 1” can be replaced with each other. “Less than or equal to” and “less than” can be replaced with each other, for example, “B is less than threshold 2” and “B is less than or equal to threshold 2” can be replaced with each other.

[0143] Twelve, in this application, the sampling window can have other names, such as channel impulse response window, feedback window, etc., which are not limited. The size of the sampling window can also have other names, such as the length of the sampling window, the size of the sampling window, or the time corresponding to the sampling window, etc., which are not limited.

[0144] Thirteen, in this application, “in the case of”, “when”, “if”, and “if” can represent the same meaning, and can be replaced with each other.

[0145] Fourteen, in the following FIG. 5 and FIG. 9A to FIG. 9L, the horizontal coordinate can be the transmission delay of the sensing signal, the unit of the transmission delay is, for example, nanosecond (ns), and t0 is the transmission delay corresponding to the reference sampling point; or, the horizontal coordinate can be the transmission distance of the sensing signal, the unit of the transmission distance is, for example, meter (m), and t0 is the transmission distance corresponding to the reference sampling point; or, the horizontal coordinate can be the index of the sampling point, the time interval between adjacent sampling points is Δt, and the position of t0 is the position of the index of the reference sampling point, t0 is the transmission delay or transmission distance corresponding to the reference sampling point. The specific content of the reference sampling point will be described in the following mode b1, which is not expanded here. The vertical coordinate can be the sensing measurement result (for example, channel impulse response information).

[0146] In the following FIG. 6B and FIG. 6C, the horizontal coordinate can be the transmission distance of the sensing signal, and the unit of the transmission distance is, for example, meter. The vertical coordinate can be the channel impulse response.

[0147] Among them, the sensing measurement result (for example, channel impulse response information) can be a complex number, which can be expressed as I+jQ, or can be expressed as amplitude+phase. When the complex number is expressed as I+jQ, I can represent the real part of the complex number, and Q can represent the imaginary part of the complex number. I and Q are both real numbers. I and Q can be expressed in linear or in decibels (dB). When the complex number is expressed as amplitude+phase, the complex number can be expressed as Ae jθwherein A can represent an amplitude, and 0 can represent a phase. The amplitude A can be represented in linear, or can be represented in dB. The phase 0 can be represented in radian, with a range of 0~2π, or can be represented in degree, with a range of 0~360°. Optionally, the value of the ordinate can be a linear value of the perception measurement result. Alternatively, the value of the ordinate can be a quantized value of the perception measurement result, for example, can be a value quantized from the perception measurement result in 16 bits. Wherein the quantized range can be 0 to CIRmax, and CIRmax can be 2 16 Correspondingly, for example, CIRmax can be 2 16 -1.

[0148] In the present application, the transmission delay can be replaced by the propagation delay; and the transmission distance can be replaced by the propagation distance.

[0149] At present, the receiving device of the perception signal can obtain and feed back the perception measurement result corresponding to the sampling point in the sampling window. Wherein the sampling window can be associated with the region of interest. For example, the region of interest is shown in (1) of FIG. 5, and the associated sampling window is shown in (2) of FIG. 5. In this way, the perception measurement result corresponding to the sampling point in the sampling window can be used to locate the object to be measured in the region of interest. It should be understood that FIG. 5 takes one region of interest and one sampling window as an example for illustration, and the number of regions of interest and / or sampling windows can be greater than 1, which is not limited.

[0150] The perception measurement result corresponding to the sampling point outside the sampling window can interfere with the perception measurement result corresponding to the sampling point in the sampling window.

[0151] For example, as shown in FIG. 6A, the action point 1 is located outside the region of interest; the sensing measurement result of the sensing signal passing through the action point 1 is the sensing measurement result corresponding to the sampling point outside the sampling window. The action point 2 is located inside the region of interest; the sensing measurement result of the sensing signal passing through the action point 2 is the sensing measurement result corresponding to the sampling point in the sampling window. Taking the channel impulse response information as an example, FIG. 6B shows the channel impulse response information of the sensing signal passing through the action point 1 and the channel impulse response information of the sensing signal passing through the action point 2. If the main lobe amplitude of the channel impulse response information of the sensing signal passing through the action point 1 is high, the channel impulse response information of the sensing signal passing through the action point 2 will be affected by the side lobe leakage. For example, the channel impulse response information of the sensing signal passing through the action point 1 and the channel impulse response information of the sensing signal passing through the action point 2 are superimposed to obtain the channel impulse response information shown in FIG. 6C. Assuming that the transmission distance of the sensing signal passing through the action point 1 is 300 meters, that is, the sum of the distances from the action point 1 to the access network device and the terminal is 300 meters. The transmission distance of the sensing signal passing through the action point 2 is 310 meters, that is, the sum of the distances from the action point 2 to the access network device and the terminal is 310 meters. In this case, the peak position of the channel impulse response information of the sensing signal passing through the action point 2 can be shifted by 0.3 meters, and the amplitude can be changed by 20%.

[0152] Therefore, the sensing measurement result corresponding to the sampling point outside the sampling window can interfere with the sensing measurement result corresponding to the sampling point in the sampling window. How to reduce or avoid the influence of the interference on the sensing processing needs further research.

[0153] Next, the execution subject involved in the embodiments of the present application is introduced.

[0154] The first device can be used for sensing (or performing sensing); or in other words, the first device can be a sensing node. The first device can be a terminal or an access network device, or a device (such as a module, a communication module, a circuit, a chip (such as a modem chip, or a SoC chip or a SIP chip containing a modem core), a chip system or a processor) applied to a terminal or an access network device, or a logic node, a logic module or software capable of realizing all or part of the functions of a terminal or an access network device.

[0155] For example, the first device can be the access network device A or a device in the access network device A shown in (1) or (6) in FIG. 3; or the first device can be the terminal A or a device in the terminal A shown in (2) or (5) in FIG. 3; or the first device can be the access network device B or a device in the access network device B shown in (3) or (7) in FIG. 3; or the first device can be the terminal B or a device in the terminal B shown in (4) or (8) in FIG. 3.

[0156] Optionally, the device sending the sensing signal can be the access network device A or a device in the access network device A shown in any of (1), (3), (5) or (7) in FIG. 3; or the device sending the sensing signal can be the terminal A or a device in the terminal A shown in any of (2), (4), (6) or (8) in FIG. 3.

[0157] In some implementations, the first device can be a receiving device or a device in a receiving device in a multi-to-one scenario; in other words, the first device can receive the echo signal of the sensing signal from multiple devices. For example, a terminal receives the echo signal of the sensing signal from multiple access network devices, and the first device can be the terminal or a device in the terminal.

[0158] In some other implementations, the first device can be a receiving device or a device in a receiving device in a one-to-multi scenario; in other words, the first device can receive the echo signal of the sensing signal from one device. For example, a terminal sends the sensing signal to multiple access network devices, and the first device can be any of the multiple access network devices or a device in any of the multiple access network devices.

[0159] The second device can be configured to manage the sensing; in other words, the second device can be a node managing the sensing. Optionally, the second device can be or include a sensing management function. The details of the sensing management function can refer to the description of the sensing management function in the description of the communication system shown in FIG. 1B, and will not be repeated here.

[0160] In some possible manners, the first device and the second device are located in the same device (e.g., a terminal or an access network device). For example, the first device can implement the function of the second device; or the first device and the second device are the same device. For another example, the first device and the second device can be devices in the same device implementing different functions. In this manner, the step of transmitting information (or a message) between the first device and the second device is an optional step.

[0161] In some other possible manners, the first device and the second device are located in different apparatuses. For example, the first device can be the access network apparatus A in (1) of FIG. 3, or a device in the access network apparatus A; the second device can be a perception management function independent of the access network apparatus A. For another example, the first device can be the terminal A in (2) of FIG. 3, or a device in the terminal A; the second device can be an access network apparatus or a device in the access network apparatus accessed by the terminal A, or the second device can be a perception management function independent of the terminal A and the access network apparatus accessed by the terminal A. For yet another example, the first device can be the access network apparatus B in (3) of FIG. 3, or a device in the access network apparatus B; the second device can be a perception management function independent of the access network apparatus B. For yet another example, the first device can be the terminal B in (4) of FIG. 3, or a device in the terminal B; the second device can be an access network apparatus or a device in the access network apparatus accessed by the terminal B, or the second device can be a perception management function independent of the terminal B and the access network apparatus accessed by the terminal B. For yet another example, the first device can be the terminal A in (5) of FIG. 3, or a device in the terminal A; the second device can be an access network apparatus (for example, the access network apparatus A in (5) of FIG. 3) or a device in the access network apparatus accessed by the terminal A, or the second device can be a perception management function independent of the terminal A and the access network apparatus accessed by the terminal A. For yet another example, the first device can be the access network apparatus A in (6) of FIG. 3, or a device in the access network apparatus A; the second device can be a perception management function independent of the access network apparatus A. For example, the first device can be the access network apparatus B in (7) of FIG. 3, or a device in the access network apparatus B; the second device can be the access network apparatus C in (7) of FIG. 3, or a device in the access network apparatus C. For another example, the first device can be the terminal B in (8) of FIG. 3, or a device in the terminal B; the second device can be the access network apparatus A in (8) of FIG. 3, or a device in the access network apparatus A.

[0162] Embodiments of the present application provide a communication method. FIG. 7 is a flowchart of the communication method provided by embodiments of the present application. Optionally, the method can be applied to a cellular network. In FIG. 7, the method is exemplified by taking a first device and a second device as the execution subjects of the interaction. The first device can be a terminal or a device (e.g., a module, a communication module, a circuit, a chip (such as a modem chip, or a SoC chip or a SIP chip containing a modem core), a chip system, or a processor) in the terminal, or a logic node, a logic module, or software for implementing all or part of the functions of the terminal. The second device can be an access network device or a device (e.g., a module, a communication module, a circuit, a chip (such as a modem chip, or a SoC chip or a SIP chip containing a modem core), a chip system, or a processor) in the access network device, or a logic node, a logic module, or software for implementing all or part of the functions of the access network device.

[0163] As shown in FIG. 7, the method includes the following steps.

[0164] S701: The first device obtains a first perception measurement result corresponding to a sampling point in a sampling window.

[0165] Exemplarily, the first device can measure a perception signal at the sampling point in the sampling window to obtain the first perception measurement result corresponding to the sampling point in the sampling window. The first perception measurement result can be raw data of the perception, or data obtained by processing (e.g., one or more of dimension alignment, up-sampling, or down-sampling) the raw data of the perception, or features obtained by processing the raw data of the perception through a neural network, or perception data obtained by performing a fusion operation on the raw data of the perception.

[0166] Optionally, the first perception measurement result can correspond to at least one sampling point, which can be part or all of the sampling points in the sampling window. The at least one sampling point can be determined according to information #1 from the second device; in other words, the second device sends information #1, and the first device receives the information #1, which can be used to determine the at least one sampling point. The specific content of the determination will be described below in modes b1 to b5, which will not be expanded here.

[0167] The sampling window is associated with a region of interest; in other words, the sampling window can be determined according to the region of interest. Optionally, the number of sampling windows can be one or more; and the number of regions of interest can be one or more. Optionally, the region of interest can include at least one of the following: a region where an object to be measured is located, a region to be measured, a target measurement region, or a field of view (FOV). The object to be measured can be replaced by at least one of the following: a target to be measured, a perception target, or a perception target to be measured, etc.

[0168] The way of associating the sampling window with the region of interest can be various, for example, way a1 or way a2.

[0169] Way a1: the sampling window can be one sampling window (hereinafter referred to as the first sampling window), and the first sampling window is associated with one or more regions of interest.

[0170] For example, as shown in FIG. 8, the one or more regions of interest include region of interest #1 and region of interest #2. The region of interest #1 and the region of interest #2 are associated with the first sampling window. The first sampling window can be the sampling window shown in FIG. 9A. The first 4 sampling points in the sampling window can be associated with the region of interest #1 for measuring the perception signal passing through the perception target in the region of interest #1. The last 4 sampling points in the sampling window can be associated with the region of interest #2 for measuring the perception signal passing through the perception target in the region of interest #2.

[0171] It should be understood that the example takes two regions of interest as an example for illustration, and in actual application, there can be more or less regions of interest, which are not limited.

[0172] It should be understood that in FIG. 9A and FIG. 9B to FIG. 9J below, the sampling points associated with two regions of interest are taken as an example for illustration. In actual application, there can be more or less regions of interest; the sampling points associated with different regions of interest can be partially or totally overlapped, or the sampling points associated with different regions of interest can not be overlapped, which are not limited.

[0173] The first sampling window associated with the one or more regions of interest can be replaced by at least one of the following: the parameters of the first sampling window are associated with the one or more regions of interest; or, the parameters of the first sampling window are determined according to the one or more regions of interest.

[0174] Optionally, the parameters of the first sampling window can include at least one of the following: the size of the first sampling window, or the offset of the starting position of the first sampling window relative to the reference sampling point. This will be described respectively below.

[0175] 1. The size of the first sampling window:

[0176] The size of the first sampling window can be associated with d max1 and d min1 . The size of the first sampling window can be associated with d max1 and d min1 , which can be replaced by: the size of the first sampling window is determined according to d max1 and d min1 .

[0177] wherein, dmax1 is a maximum value of d i min1 is a minimum value of d i . is a distance between point P i and a transmitting device of the perception signal, is a distance between point P i and a receiving device of the perception signal. In other words, d max1 is a sum of a distance from the first point to the transmitting device and a distance from the first point to the receiving device, the first point being a point in the one or more regions of interest with a maximum sum of the distance to the transmitting device and the distance to the receiving device; d min1 is a sum of a distance from the second point to the transmitting device and a distance from the second point to the receiving device, the second point being a point in the one or more regions of interest with a minimum sum of the distance to the transmitting device and the distance to the receiving device. The receiving device can be the first device or a device where the first device is located.

[0178] Still taking FIG. 8 as an example, for the region of interest #1, d i ranges from 120 to 150 meters; for the region of interest #2, d i ranges from 180 to 210 meters. In this case, d max1 is 210 meters, and d min1 is 120 meters. The size of the first sampling window is determined according to 210 meters and 120 meters. For example, the size of the first sampling window can be W length1 in FIG. 9A.

[0179] It should be understood that the example takes two regions of interest as an example, and in actual applications, there can be more or fewer regions of interest; the value ranges of d i corresponding to different regions of interest can partially or wholly overlap, or the value ranges of d i corresponding to different regions of interest can not overlap, which is not limited.

[0180] In this way, d max1 and d min1 can be used to accurately determine the size of the first sampling window.

[0181] Alternatively, the size of the first sampling window can be represented as W length1 , and the association of W length1 with d max1 and d min1 may be as shown in one of formulas (1) to (4); in other words, W length1 satisfies one of formulas (1) to (4): ​

[0182] wherein c is the speed of light, and Δt is the time interval between adjacent sample points of the channel impulse response, denotes a rounding up operation, denotes a rounding down operation, and round() denotes a rounding operation.

[0183] There can be multiple manners to determine Δt. For example, Δt can be preconfigured, e.g., specified by a protocol; or Δt can be determined by the second device, and optionally, after determining Δt, the second device can send information indicating Δt to the first device; or Δt can be indicated by another device, e.g., the first device or a core network device, to the second device, e.g., the other device can send information indicating Δt to the second device.

[0184] The application does not limit the manner of indicating the information indicating Δt. In some examples, the information indicating Δt can explicitly indicate Δt. In other examples, the information indicating Δt can implicitly indicate Δt. For example, the information indicating Δt can indicate a sampling frequency of the channel impulse response, and Δt = 1 / sampling frequency. For another example, the information indicating Δt can indicate a distance interval corresponding to adjacent sample points of the channel impulse response, and Δt = distance interval / c.

[0185] The time interval between adjacent sample points of the channel impulse response can also be referred to as a sampling time interval, or a sampling interval, as long as it has the same function, which is within the protection scope of the application.

[0186] By the method, the above formula can be used to accurately determine the size of the first sampling window. In addition, by any one of the formulas (2) to (4), the size of the first sampling window can be an integer multiple of the time interval between adjacent sample points of the channel impulse response; currently, the communication device performs signal processing at the baseband, and the signal processing at the baseband is discrete sampling according to the sampling frequency of the channel impulse response, which is the inverse of the time interval between adjacent sample points of the channel impulse response, therefore, the size of the first sampling window obtained by any one of the formulas (2) to (4) can be matched with the signal processing operation at the baseband.

[0187] It should be understood that the above formulas (1) to (4) are only examples, and W length1 The association manner of d max1 and d min1 is not limited thereto.

[0188] 2. Offset of the start position of the first sampling window relative to the reference sample point:

[0189] The offset of the start position of the first sampling window relative to the reference sampling point can be associated with d min1 . The offset of the start position of the first sampling window relative to the reference sampling point can be associated with d ref . The offset of the start position of the first sampling window relative to the reference sampling point can be associated with d min1 . The offset of the start position of the first sampling window relative to the reference sampling point can be associated with d ref . The offset of the start position of the first sampling window relative to the reference sampling point can be determined according to d min1 . The offset of the start position of the first sampling window relative to the reference sampling point can be determined according to d ref .

[0190] The specific content of d min1 may refer to the description of d min1 in the above "1, size of the first sampling window", which will not be repeated here. d ref is the distance between the sending device and the receiving device of the perception signal. The receiving device can be the first device or the device where the first device is located. The specific content of the reference sampling point will be described in the following mode b1, which will not be expanded here.

[0191] Still taking FIG. 8 as an example, for the region of interest #1, the value range of d i is 120-150 meters; for the region of interest #2, the value range of d i is 180-210 meters. The distance between the sending device and the receiving device of the perception signal is 100 meters. In this case, d min1 is 120 meters, and d ref is 100 meters. The offset of the start position of the first sampling window relative to the reference sampling point is determined according to 120 meters and 100 meters. For example, the offset of the start position of the first sampling window relative to the reference sampling point can be W offset1 in FIG. 9A.

[0192] It should be understood that this example takes two regions of interest as an example, and in actual application, there can be more or fewer regions of interest; the value range of d i corresponding to different regions of interest can partially or completely overlap, or the value range of d i corresponding to different regions of interest can not overlap, which is not limited.

[0193] In this way, d min1 and d ref can be used to accurately determine the offset of the start position of the first sampling window relative to the reference sampling point.

[0194] Alternatively, the offset of the start position of the first sampling window relative to the reference sampling point can be represented as W offset1 , W offset1 , d min1 and d refThe association manner of d offset1 satisfies one of formulas (5) to (8):

[0195] The content of each parameter and operator symbol in formulas (5) to (8) can refer to the description of each parameter and operator symbol in formulas (1) to (4) and will not be repeated here.

[0196] Through the method, the above formulas can be used to accurately determine the offset of the starting position of the first sampling window relative to the reference sampling point. In addition, through any one of formulas (6) to (8), the offset of the starting position of the first sampling window relative to the reference sampling point can be an integer multiple of the time interval between adjacent sampling points of the channel impulse response. At present, the communication device performs signal processing in the baseband, and the signal processing in the baseband is discrete sampling according to the sampling frequency of the channel impulse response, which is the inverse of the time interval between adjacent sampling points of the channel impulse response. Therefore, the offset of the starting position of the first sampling window relative to the reference sampling point obtained through any one of formulas (6) to (8) can match the signal processing operation in the baseband.

[0197] It should be understood that the above formulas (5) to (8) are only examples, and the association manner of d offset1 and d min1 and d ref is not limited thereto.

[0198] Optionally, in the case where the distance (i.e., d ref ) between the sending device and the receiving device of the perception signal is 0, the offset of the starting position of the first sampling window relative to the reference sampling point can be associated with d min1 and d ref , which can be replaced by (or can be understood as) that the offset of the starting position of the first sampling window relative to the reference sampling point can be associated with d min1 ; and / or, in the above formulas (5) to (8), “-d ref ” can be excluded, for example, formula (5) can be changed to and / or, in FIG. 9A, the value of t0 is 0.

[0199] Through mode a1, the first sampling window is associated with one or more regions of interest, so that the first device can obtain and feed back the perception measurement result related to the one or more regions of interest according to the first sampling window.

[0200] In addition, in the manner, the first sampling window is associated with one or more regions of interest. In this way, for the one or more regions of interest, the indication of the sampling window between the first device and the second device can be only one sampling window, without the need to indicate the sampling window corresponding to each region of interest respectively, thereby reducing the signaling overhead.

[0201] Manner a2: the sampling window is at least one sampling window, and each sampling window in the at least one sampling window is associated with one region of interest in the one or more regions of interest.

[0202] In addition, in the manner, the first sampling window is associated with one or more regions of interest. In this way, for the one or more regions of interest, the indication of the sampling window between the first device and the second device can be only one sampling window, without the need to indicate the sampling window corresponding to each region of interest respectively, thereby reducing the signaling overhead.

[0203] For example, as shown in FIG. 8, the one or more regions of interest include a region of interest #1 and a region of interest #2. As shown in FIG. 9B, the at least one sampling window can include a sampling window #1 and a sampling window #2. The sampling window #1 can be associated with the region of interest #1, and used to measure the perception signal passing through the perception target in the region of interest #1. The sampling window #2 can be associated with the region of interest #2, and used to measure the perception signal passing through the perception target in the region of interest #2.

[0204] It should be understood that the example is described by taking two regions of interest as an example, and in actual application, there can be more or less regions of interest, which is not limited.

[0205] The at least one sampling window includes a second sampling window, which is taken as an example below. The other sampling windows in the at least one sampling window can refer to the second sampling window, and will not be described herein.

[0206] In some implementations, the second sampling window is associated with a first region of interest in the one or more regions of interest. In this way, the association of the second sampling window with the first region of interest can be replaced by at least one of the following: the parameters of the second sampling window are associated with the first region of interest; or, the parameters of the second sampling window are determined according to the first region of interest.

[0207] Optionally, the parameters of the second sampling window can include at least one of the following: the size of the second sampling window, or the offset of the starting position of the second sampling window relative to the reference sampling point. This will be described respectively below.

[0208] 1. The size of the second sampling window:

[0209] The size of the second sampling window is d max2 and d min2correlation. The size of the second sampling window is determined according to d max2 and d min2 correlation, the size of the second sampling window can be replaced by: the size of the second sampling window is determined according to d max2 and d min2 .

[0210] where d max2 is the maximum value of d j , and d min2 is the minimum value of d j . is the distance between the point P j in the first region of interest and the sending device of the perception signal, is the distance between the point P j and the receiving device of the perception signal. In other words, d max2 is the sum of the distance from the third point to the sending device and the distance from the third point to the receiving device, the third point being the point in the first region of interest with the maximum sum of the distance to the sending device and the distance to the receiving device; d min2 is the sum of the distance from the fourth point to the sending device and the distance from the fourth point to the receiving device, the fourth point being the point in the first region of interest with the minimum sum of the distance to the sending device and the distance to the receiving device. The receiving device can be the first device or the device where the first device is located.

[0211] Still taking FIG. 8 as an example, for the region of interest #1, the value range of d j is 120-150 meters; for the region of interest #2, the value range of d j is 180-210 meters. In the case where the first region of interest is the region of interest #1, d max2 is 150 meters, and d min2 is 120 meters; the size of the second sampling window is determined according to 150 meters and 120 meters, for example, the size of the second sampling window is W length2 1 in FIG. 9B. In the case where the first region of interest is the region of interest #2, d max2 is 210 meters, and d min2 is 180 meters; the size of the second sampling window is determined according to 210 meters and 180 meters, for example, the size of the second sampling window is W length2 2 .

[0212] It should be understood that the example takes two regions of interest as an example, and in actual application, there can be more or fewer regions of interest; the value ranges of d j corresponding to different regions of interest can partially or wholly overlap, or the value ranges of d jThe value range of d

[0213] In this way, d max2 and d min2 may be used to accurately determine the size of the second sampling window.

[0214] Alternatively, the size of the second sampling window can be expressed as W length2 , W length2 is associated with d max2 and d min2 may be as shown in one of formulas (9) to (12), in other words, W length2 satisfies one of formulas (9) to (12):

[0215] The content of each parameter and operator symbol in formulas (9) to (12) can be referred to the description of each parameter and operator symbol in formulas (1) to (4), and will not be repeated here.

[0216] In this way, the above formulas can be used to accurately determine the size of the second sampling window. In addition, according to any one of formulas (10) to (12), the size of the second sampling window can be an integer multiple of the time interval between adjacent sampling points of the channel impulse response; at present, the communication device performs signal processing in the baseband, and the signal processing in the baseband is discrete sampling according to the sampling frequency of the channel impulse response, which is the inverse of the time interval between adjacent sampling points of the channel impulse response. Therefore, the size of the second sampling window obtained by any one of formulas (10) to (12) can be matched with the signal processing operation in the baseband.

[0217] It should be understood that the above formulas (9) to (12) are only examples, and the association between W length2 and d max2 and d min2 is not limited thereto.

[0218] 2. The offset of the starting position of the second sampling window relative to the reference sampling point:

[0219] The offset of the starting position of the second sampling window relative to the reference sampling point can be associated with d min2 and d ref . The offset of the starting position of the second sampling window relative to the reference sampling point can be associated with d min2 and d ref , which can be replaced by: the offset of the starting position of the second sampling window relative to the reference sampling point is determined according to d min2 and d ref .

[0220] where dThe specific content of d min2 may refer to the description of d min2 in the above "1, size of the second sampling window", which will not be repeated here. ref is the distance between the sending device and the receiving device of the awareness signal. The receiving device can be the first device or the device where the first device is located. The specific content of the reference sampling point will be described in the following mode b1, which will not be expanded here.

[0221] Still taking FIG. 8 as an example, for the region of interest #1, the value range of d j is 120-150 meters; for the region of interest #2, the value range of d j is 180-210 meters. The distance between the sending device and the receiving device of the awareness signal is 100 meters. In the case where the first region of interest is the region of interest #1, d min2 is 120 meters, d ref is 100 meters; the offset of the starting position of the second sampling window relative to the reference sampling point is determined according to 120 meters and 100 meters, for example, the offset of the starting position of the second sampling window relative to the reference sampling point is W offset2 1 In the case where the first region of interest is the region of interest #2, d min2 is 180 meters, d ref is 100 meters; the offset of the starting position of the second sampling window relative to the reference sampling point is determined according to 180 meters and 100 meters, for example, the offset of the starting position of the second sampling window relative to the reference sampling point is W offset2 2 .

[0222] It should be understood that this example takes two regions of interest as an example, and in actual application, there can be more or fewer regions of interest; the value range of d j corresponding to different regions of interest can partially or totally overlap, or the value range of d j corresponding to different regions of interest can not overlap, which is not limited.

[0223] Through this method, d min2 and d ref can be used to accurately determine the offset of the starting position of the second sampling window relative to the reference sampling point.

[0224] Alternatively, the offset of the starting position of the second sampling window relative to the reference sampling point can be represented as W offset2 , W offset2 and the association mode of d min2 and d ref may be as shown in one of formulas (13)-(16); in other words, W offset2satisfying one of the following equations (13) to (16):

[0225] The content of each parameter and operator symbol in the equations (13) to (16) can refer to the description of each parameter and operator symbol in the equations (1) to (4), and will not be repeated here.

[0226] Through the method, the above equations can be used to accurately determine the offset of the starting position of the second sampling window relative to the reference sampling point. In addition, through any one of the equations (14) to (16), the offset of the starting position of the second sampling window relative to the reference sampling point can be an integer multiple of the time interval between adjacent sampling points of the channel impulse response; at present, the communication device performs signal processing in the baseband, and the signal processing in the baseband is discrete sampling according to the sampling frequency of the channel impulse response, which is the inverse of the time interval between adjacent sampling points of the channel impulse response, therefore, the offset of the starting position of the second sampling window relative to the reference sampling point obtained through any one of the equations (14) to (16) can match the signal processing operation in the baseband.

[0227] It should be understood that the above equations (13) to (16) are only examples, and W offset2 The association manner of d min2 and d ref is not limited thereto.

[0228] Optionally, in the case that the distance (i.e. d ref ) between the sending device and the receiving device of the perception signal is 0, the offset of the starting position of the second sampling window relative to the reference sampling point can be associated with d min2 and d ref , and can be replaced by (or can be understood as) that the offset of the starting position of the second sampling window relative to the reference sampling point can be associated with d min2 ; and / or, in the above equations (13) to (16), “-d ref ” can be removed, for example, the equation (13) can be changed to and / or, in the figure 9B, the value of t0 is 0.

[0229] Through the manner a2, each sampling window in the at least one sampling window is associated with one of the one or more regions of interest, so that the first device can obtain and feed back the perception measurement result related to the one or more regions of interest according to the at least one sampling window.

[0230] In addition, in this manner, each region of interest can be associated with a sampling window, such that each sampling point within the sampling window is associated with the region of interest. The first device can only report the perception measurement result corresponding to the sampling point associated with the region of interest, and can not report the perception measurement result corresponding to the sampling point not associated with the region of interest, thereby saving the transmission overhead of the perception measurement result.

[0231] Optionally, the sampling window can be determined by the second device according to the region of interest. For example, the second device can determine the sampling window according to the region of interest by using the manner a1 or the manner a2.

[0232] Before determining the sampling window, the second device can determine the region of interest. The region of interest can be determined in various manners, which will be exemplarily described below. In some implementations, the region of interest can be determined by the second device itself. For example, the second device can determine the region of interest according to the perception service. For example, in the case that the perception service is dynamic vehicle target detection, the second device can determine that the region of interest includes the region where the road is located. For another example, in the case that the perception service is static environment reconstruction, the second device can determine that the region of interest includes the region beside the road. In other implementations, the region of interest can be indicated to the second device by another device (e.g., the first device or a core network device). In yet other implementations, the region of interest can be preset, for example, specified by a protocol. For example, the region of interest can include the region where the electronic fence is located. It should be understood that the region of interest can also be determined in other manners, which are not limited.

[0233] The region of interest can be represented in various manners, which will be exemplarily described below. In some examples, the region of interest can be represented by the coordinates of the region. In other examples, the region of interest can be represented by a geographical region, for example, if the geographical region is A park, it means that the region of interest includes the range of A park. In yet other examples, the region of interest can be indicated by the identity of one or more cells, for example, if the identity of one or more cells includes the identity of cell #1 and cell #2, it means that the region of interest includes the coverage (or service range) of cell #1 and cell #2. It should be understood that the region of interest can also be represented in other manners, which are not limited.

[0234] As described above, the information #1 can be used to determine the at least one sampling point; accordingly, the first device can determine the at least one sampling point according to the information #1. The determination can be performed in various manners, for example, at least one of the manner b1 to the manner b5. In the manner b1 to the manner b5, the at least one sampling point can belong to at least one sampling window.

[0235] In some examples, the information #1 indicates the at least one sampling window, and the at least one sampling point includes all sampling points in the at least one sampling window. Accordingly, the first device can determine the at least one sampling window according to the information #1, and determine that the at least one sampling point includes all sampling points in the at least one sampling window.

[0236] In some examples, the information #1 indicates the at least one sampling window can be the first sampling window in the manner a1, and the at least one sampling point can include all sampling points in the first sampling window. For example, the first sampling window is the sampling window shown in FIG. 9A, and the at least one sampling point can include all sampling points in the sampling window shown in FIG. 9A.

[0237] In other examples, the information #1 indicates the at least one sampling window can be the at least one sampling window in the manner a2, and the at least one sampling point can include all sampling points in the at least one sampling window. For example, the at least one sampling window includes the sampling window #1 and the sampling window #2 shown in FIG. 9B. The at least one sampling point can include all sampling points in the sampling window #1 and all sampling points in the sampling window #2.

[0238] The following describes the manner in which the information #1 indicates the at least one sampling window.

[0239] In some implementations, the information #1 can indicate at least one of the following: an offset of a reference position of each sampling window in the at least one sampling window relative to a reference sampling point, a size of each sampling window in the at least one sampling window, or a period of each sampling window in the at least one sampling window. The reference position can be, for example, a start position, an end position, a center position, or a position specified by a protocol or convention. The period of a sampling window can be understood as a duration of sampling performed by the sampling window.

[0240] In some examples, the information #1 can indicate the offset of the reference position of each sampling window in the at least one sampling window relative to the reference sampling point, the size of each sampling window in the at least one sampling window, and the period of each sampling window in the at least one sampling window.

[0241] For example, the at least one sampling window is the sampling window shown in FIG. 9A; the information #1 can indicate the offset W offset1 of the start position of the sampling window relative to the reference sampling point, the size W length1 of the sampling window, and the period #1 of the sampling window. As shown in FIG. 9C, within the period #1, there can be at least one sampling window shown in FIG. 9A. The first device can determine the offset W offset1 , the size W length1determining at least one sampling window in the period #1 according to the t0, W

[0242] For example, the at least one sampling window can include the sampling window #1 and the sampling window #2 shown in FIG. 9B; the information #1 can indicate that the offset of the start position of the sampling window #1 relative to the reference sampling point is W offset2 1 , the size of the sampling window #1 is W length2 1 , the period #2 of the sampling window #1, the offset of the start position of the sampling window #2 relative to the reference sampling point is W offset2 2 , the size of the sampling window #2 is W length2 2 , and the period #3 of the sampling window #2. As shown in FIG. 9D, in the period #2, there can be at least one sampling window #1; in the period #3, there can be at least one sampling window #2. The first device can determine the sampling window #1 in the period #2 according to the t0, W offset2 1 , and W length2 1 ; and determine the sampling window #2 in the period #3 according to the t0, W offset2 2 , and W length2 2 . It should be understood that the periods of different sampling windows in the at least one sampling window can be the same or different, and FIG. 9D illustrates the case where the periods of different sampling windows are different.

[0243] In some other examples, the information #1 can indicate the offset of the reference position of each sampling window in the at least one sampling window relative to the reference sampling point, and the size of each sampling window in the at least one sampling window.

[0244] For example, the at least one sampling window can be the sampling window shown in FIG. 9A; the information #1 can indicate that the offset of the start position of the sampling window relative to the reference sampling point is W offset1 , and the size of the sampling window is W length1 . In this way, the first device can determine the sampling window shown in FIG. 9A according to the t0, W offset1 , and W length1 .

[0245] For example, the at least one sampling window can include sampling window #1 and sampling window #2 shown in FIG. 9B; information #1 can indicate: offset W of the start position of sampling window #1 relative to the reference sampling point offset2 1 , size W of sampling window #1 length2 1 , offset W of the start position of sampling window #2 relative to the reference sampling point offset2 2 , and size W of sampling window #2 length2 2 . In this way, the first device can determine sampling window #1 according to t0, W offset2 1 , and W length2 1 ; determine sampling window #2 according to t0, W offset2 2 , and W length2 2 .

[0246] It should be understood that the manner in which information #1 indicates the at least one sampling window is not limited to this. For example, information #1 can indicate the first sampling point or the last sampling point in each sampling window, and the number of sampling points contained in each sampling window. For another example, information #1 can indicate the first sampling point and the last sampling point in each sampling window.

[0247] In the above manner, information #1 can accurately indicate the at least one sampling window; accordingly, the first device can accurately determine the at least one sampling window according to information #1.

[0248] In some implementations, information #1 can also indicate the type of the reference sampling point. The type of the reference sampling point can include at least one of: a sampling point corresponding to a direct path, a sampling point corresponding to the strongest perception measurement result, or a sampling point agreed by a common clock. The sampling point corresponding to the direct path can be replaced by at least one of: a sampling point at which a perception measurement result (or a perception signal) is first detected, a sampling point corresponding to a first detected path, or a sampling point corresponding to an earlist tap. The sampling point corresponding to the strongest perception measurement result can be replaced by at least one of: a sampling point at which a signal strength of a perception signal is strongest, or a sampling point corresponding to a strongest tap. With this implementation, the first device can accurately determine the type of the reference sampling point according to information #1.

[0249] In some examples, the type of the reference sampling point can be pre-configured, e.g., specified in a protocol. For example, the type of the reference sampling point can be pre-configured as at least one of: a sampling point corresponding to a direct path, a sampling point corresponding to a strongest measurement result, or a sampling point agreed by a common clock. With this implementation, the first device can accurately determine the type of the reference sampling point.

[0250] The type of the reference sampling point can be used to determine the reference sampling point; accordingly, the first device can determine the reference sampling point according to the type of the reference sampling point, so as to determine the at least one sampling window according to t0 corresponding to the reference sampling point.

[0251] In some examples, the reference sampling point can be determined by the first device according to the measurement. For example, in the case that the reference sampling point is a sampling point corresponding to a direct path or a sampling point corresponding to a strongest measurement result, the first device can determine the reference sampling point according to the measurement result of the perception signal.

[0252] In some other examples, the reference sampling point can be agreed by the first device and the second device, or can be indicated by the second device to the first device. For example, in the case that the reference sampling point is a sampling point agreed by a common clock, the reference sampling point can be agreed by the first device and the second device, or can be indicated by the second device to the first device.

[0253] Optionally, the reference sampling point can satisfy at least one of conditions #a1 to #a2:

[0254] Condition #a1: the transmission delay corresponding to the reference sampling point is known (or fixed or unchanged).

[0255] For example, the reference sampling point is a sampling point corresponding to a direct path. In the case that the transmitting device and the receiving device of the perception signal are fixed, the direct path is known. Therefore, the transmission delay corresponding to the direct path is known, and accordingly, the transmission delay corresponding to the reference sampling point is known, and condition #a1 is satisfied.

[0256] For another example, the reference sampling point is a sampling point corresponding to a time when a synchronization reference signal is received by the receiving device, the synchronization reference signal is transmitted by the transmitting device to the receiving device through a wired connection, and the transmission time of the synchronization reference signal is the same as the transmission time of the perception signal. In the case that the transmitting device and the receiving device of the perception signal are fixed, the arrival path of the synchronization signal is known. Therefore, the transmission delay corresponding to the arrival path of the synchronization signal is known, and accordingly, the transmission delay corresponding to the reference sampling point is known, and condition #a1 is satisfied.

[0257] For the reference sampling point satisfying condition #a1, the relative transmission time delay of any sampling point relative to the reference sampling point can be used to determine the transmission time delay and / or transmission distance corresponding to the sampling point; in this way, the perception measurement results corresponding to different sampling points can be aligned, facilitating subsequent multi-antenna angle measurement and / or velocity measurement based on the perception measurement results (e.g., channel impulse response) of different sampling points (corresponding to different times).

[0258] Condition #a2: the Doppler (or Doppler frequency offset) corresponding to the reference sampling point is 0.

[0259] Optionally, condition #a2 can be replaced by (or can be understood as) at least one of the following: the Doppler corresponding to the reference sampling point is known, fixed, and does not change over time; the range corresponding to the reference sampling point does not change during Doppler measurement; or, the Doppler corresponding to the range corresponding to the reference sampling point is known, fixed, and does not change over time.

[0260] For example, the reference sampling point is the sampling point corresponding to the direct path. In the case where the transmitting device and the receiving device of the perception signal are fixed, the Doppler corresponding to the direct path does not change over time, i.e., the Doppler corresponding to the direct path is 0, and accordingly, the Doppler corresponding to the reference sampling point is 0, condition #a2 is satisfied.

[0261] For another example, the reference sampling point is the sampling point corresponding to the time when the receiving device receives the synchronization reference signal, which is transmitted by the transmitting device to the receiving device through a wired connection, and the transmission time of the synchronization reference signal is the same as the transmission time of the perception signal. In the case where the transmitting device and the receiving device of the perception signal are fixed, the arrival path of the synchronization signal does not change over time, and accordingly, the Doppler corresponding to the reference sampling point is 0, condition #a2 is satisfied.

[0262] When performing Doppler measurement, the dynamic change of the sampling point is to be measured. Since the dynamic change is relative, for the reference sampling point satisfying condition #a2, the Doppler corresponding to any sampling point can be obtained based on the Doppler corresponding to the reference sampling point, thereby improving the accuracy of the Doppler corresponding to the sampling point.

[0263] Through mode b1, the first device can accurately determine at least one sampling window based on information #1, and accordingly, can accurately determine at least one sampling point based on the at least one sampling window.

[0264] Optionally, the first bit bitmap can be arranged in a time order of the sampling points corresponding to the at least one bit. For example, the at least one sampling window is shown in FIG. 9E, the first value is 1, and the second value is 0. If the value of the first bit bitmap is 1111001011, it indicates that the perception measurement results corresponding to the 1stto 4th, 7th, 9thto 10thsampling points in the sampling window are fed back, and the perception measurement results corresponding to the 5th, 6thand 8thsampling points in the sampling window are not fed back; in other words, the 1stto 4th, 7th, 9thto 10thsampling points in the sampling window belong to the at least one sampling point. For another example, the at least one sampling window is shown in FIG. 9F, the first value is 1, and the second value is 0. If the value of the first bit bitmap is 11111011, it indicates that the perception measurement results corresponding to the 1stto 4thsampling points in the sampling window #1 are fed back, the perception measurement results corresponding to the 1st, 3rdand 4thsampling points in the sampling window #2 are fed back, and the perception measurement result corresponding to the 2ndsampling point in the sampling window #2 is not fed back; in other words, the 1stto 4thsampling points in the sampling window #1, and the 1st, 3rdand 4thsampling points in the sampling window #2 belong to the at least one sampling point.

[0265] The specific content of the information #1 indicating the at least one sampling window can refer to the description of the “information #1 indicating the at least one sampling window” in the manner b1, and will not be described herein again. The specific manner of the information #1 indicating the first bit bitmap is not limited, for example, the information #1 can include the first bit bitmap.

[0266] In some implementations, at least one bit in the first bit bitmap can correspond to one sampling point in the at least one sampling window in a one-to-one manner. The at least one bit can be part or all of the bits in the first bit bitmap. Each bit in the at least one bit can be used to indicate whether to feed back the perception measurement result corresponding to the sampling point corresponding to the bit. For example, if the value of a certain bit in the at least one bit is a first value (for example, 1 or 0), it indicates that the perception measurement result corresponding to the sampling point corresponding to the bit is fed back; if the value of a certain bit in the at least one bit is a second value (for example, 0 or 1), it indicates that the perception measurement result corresponding to the sampling point corresponding to the bit is not fed back. The first value and the second value are different.

[0267] Optionally, the at least one bit can be arranged in a time order of the sampling points corresponding to the at least one bit. For example, the at least one sampling window is shown in FIG. 9E, the first value is 1, and the second value is 0. If the value of the first bit bitmap is 1111001011, it indicates that the perception measurement results corresponding to the 1stto 4th, 7th, 9thto 10thsampling points in the sampling window are fed back, and the perception measurement results corresponding to the 5th, 6thand 8thsampling points in the sampling window are not fed back; in other words, the 1stto 4th, 7th, 9thto 10thsampling points in the sampling window belong to the at least one sampling point. For another example, the at least one sampling window is shown in FIG. 9F, the first value is 1, and the second value is 0. If the value of the first bit bitmap is 11111011, it indicates that the perception measurement results corresponding to the 1stto 4thsampling points in the sampling window #1 are fed back, the perception measurement results corresponding to the 1st, 3rdand 4thsampling points in the sampling window #2 are fed back, and the perception measurement result corresponding to the 2ndsampling point in the sampling window #2 is not fed back; in other words, the 1stto 4thsampling points in the sampling window #1, and the 1st, 3rdand 4thsampling points in the sampling window #2 belong to the at least one sampling point.

[0268] Optionally, the number of bits in the first bitmap is greater than or equal to the number of sampling points in the at least one sampling window. For example, as shown in FIG. 9E, if the number of sampling points in the at least one sampling window is 10, the number of bits in the first bitmap is greater than or equal to 10. For another example, as shown in FIG. 9F, if the number of sampling points in the at least one sampling window is 8, the number of bits in the first bitmap is greater than or equal to 8.

[0269] According to the information #1, the first device can accurately determine the at least one sampling window and the first bitmap, and accurately determine the at least one sampling point according to the at least one sampling window and the first bitmap.

[0270] In addition, in this way, the first bitmap can indicate whether to feed back the perception measurement result corresponding to the sampling point in the at least one sampling window, so that the first device can not feed back the perception measurement result corresponding to all sampling points in the at least one sampling window, thereby reducing the feedback overhead of the perception measurement result.

[0271] In addition, in the case that the at least one sampling window is the first sampling window in the way a1, the first bitmap can indicate to feed back the perception measurement result corresponding to the sampling point associated with the one or more regions of interest in the first sampling window, and not to feed back the perception measurement result corresponding to the sampling point not associated with the one or more regions of interest in the first sampling window, so that the feedback perception measurement result is related to the one or more regions of interest.

[0272] Way b3: The information #1 indicates the at least one sampling window. The at least one sampling point includes: the sampling point in the at least one sampling window whose corresponding perception measurement result is greater than a first threshold. Correspondingly, the first device can determine the at least one sampling window according to the information #1, and determine the at least one sampling point according to the at least one sampling window and the first threshold.

[0273] The specific content of the information #1 indicating the at least one sampling window can refer to the description of "the information #1 indicates the at least one sampling window" in the way b1, and will not be repeated here. The first threshold can be pre-set, for example, specified by a protocol; or can be determined by the first device; or can be indicated to the first device by another device (for example, the second device or the core network equipment), for example, the information #1 can indicate the first threshold.

[0274] For example, the at least one sampling window is shown in FIG. 9G. If the first to fourth, seventh, ninth to tenth sampling points in the sampling window correspond to the perception measurement result greater than the first threshold, the at least one sampling point includes: the first to fourth, seventh, ninth to tenth sampling points in the sampling window.

[0275] For example, the at least one sampling window is shown in FIG. 9H. If the perception measurement corresponding to the 1stto 4thsampling points in sampling window #1 is greater than the first threshold, and the perception measurement corresponding to the 1st, 3rdto 4thsampling points in sampling window #2 is greater than the first threshold, the at least one sampling point includes the 1stto 4thsampling points in sampling window #1, and the 1st, 3rdto 4thsampling points in sampling window #2.

[0276] According to the information #1, the first device can accurately determine the at least one sampling window, and accurately determine the at least one sampling point according to the at least one sampling window and the first threshold.

[0277] In addition, in this way, the at least one sampling point includes the sampling points in the at least one sampling window whose corresponding perception measurement is greater than the first threshold. Thus, the first device can not feed back the perception measurement corresponding to all the sampling points in the at least one sampling window, thereby reducing the feedback overhead of the perception measurement.

[0278] Way b4: The information #1 indicates the at least one sampling window and a second bit map. The second bit map indicates whether to feed back the perception measurement corresponding to each group of sampling points in the at least one group of sampling points; in other words, the second bit map indicates whether each group of sampling points in the at least one group of sampling points contains the sampling points belonging to the at least one sampling point. The at least one group of sampling points belongs to the at least one sampling window. Correspondingly, the first device can determine the at least one sampling window and the second bit map according to the information #1, and determine the at least one sampling point according to the at least one sampling window and the second bit map.

[0279] The specific content of the information #1 indicating the at least one sampling window can refer to the description of the information #1 indicating the at least one sampling window in way b1, and will not be described herein. The specific way of the information #1 indicating the second bit map is not limited. For example, the information #1 can include the second bit map.

[0280] In some implementations, one or more bits in the second bit map can correspond to the at least one group of sampling points one by one. The one or more bits can be part or all of the bits in the second bit map. Each bit in the one or more bits can be used to indicate whether to feed back the perception measurement corresponding to the sampling points in the group corresponding to the bit. For example, if the value of a certain bit in the one or more bits is a third value (for example, 1 or 0), it indicates to feed back the perception measurement of the sampling points in the group corresponding to the bit; if the value of a certain bit in the one or more bits is a fourth value (for example, 0 or 1), it indicates not to feed back the perception measurement of the sampling points in the group corresponding to the bit. The third value and the fourth value are different.

[0281] For example, the one or more bits can be arranged in the order of time from front to back of the sampling points in their corresponding groups. For example, the at least one sampling window is shown in FIG. 91, the third value is 1, and the fourth value is 0. If the value of the second bit map is 10011, it indicates that the perception measurement results corresponding to the sampling points in the first, fourth and fifth groups in the feedback sampling window are fed back, and the perception measurement results corresponding to the sampling points in the second and third groups in the non-feedback sampling window are not fed back. For another example, the at least one sampling window is shown in FIG. 9J, the third value is 1, and the fourth value is 0. If the value of the second bit map is 1011, it indicates that the perception measurement result corresponding to the sampling points in the first group in the feedback sampling window #1 is fed back, the perception measurement results corresponding to the sampling points in the first and second groups in the feedback sampling window #2 are fed back, and the perception measurement result corresponding to the sampling points in the second group in the non-feedback sampling window #1 is not fed back.

[0282] Optionally, the number of bits in the second bit map can be greater than or equal to the number of groups of the at least one group of sampling points. For example, as shown in FIG. 91, if the number of groups of sampling points in the at least one sampling window is 5, the number of bits in the second bit map is greater than or equal to 5. For another example, as shown in FIG. 9J, if the number of groups of sampling points in the at least one sampling window is 4, the number of bits in the second bit map is greater than or equal to 4.

[0283] According to the manner b4, the first device can accurately determine the at least one sampling window and the second bit map according to the information #1, and accurately determine the at least one sampling point according to the at least one sampling window and the second bit map.

[0284] In addition, in this manner, the second bit map indicates whether the perception measurement result corresponding to each group of sampling points in the at least one group of sampling points is fed back, so that the first device can not feed back the perception measurement results corresponding to all the sampling points in the at least one sampling window, thereby reducing the feedback overhead of the perception measurement results.

[0285] In addition, this manner can group-indicate whether the perception measurement result corresponding to each group of sampling points is fed back, so that in the case that the sampling points whose perception measurement results are to be fed back are sparse, this manner does not need to explicitly indicate whether the perception measurement result corresponding to each sampling point is fed back, thereby reducing the signaling overhead.

[0286] In some implementations, in a case where the second bitmap indicates to feed back the perceptual measurement result corresponding to a first group of sampling points in the at least one group of sampling points, the at least one sampling point can include all sampling points in the first group of sampling points. For example, taking FIG. 9I as an example, in a case where the second bitmap indicates to feed back the perceptual measurement result corresponding to the 1st, 4th and 5th groups of sampling points in the sampling window, the at least one sampling point can include the 1st to 2nd, 7th to 10th sampling points in the sampling window. For another example, taking FIG. 9J as an example, in a case where the second bitmap indicates to feed back the perceptual measurement result corresponding to the 1st group of sampling points in the sampling window #1 and the perceptual measurement result corresponding to the 1st to 2nd groups of sampling points in the sampling window #2, the at least one sampling point can include the 1st to 2nd sampling points in the sampling window #1 and the 1st to 4th sampling points in the sampling window #2.

[0287] In some other implementations, in a case where the second bitmap indicates to feed back the perceptual measurement result corresponding to a first group of sampling points in the at least one group of sampling points, the information #1 can further indicate a third bitmap, the third bitmap indicating whether to feed back the perceptual measurement result corresponding to each sampling point in the first group of sampling points; in other words, the third bitmap indicates whether each sampling point in the first group of sampling points belongs to the at least one sampling point. Correspondingly, the first device can determine the at least one sampling point according to the at least one sampling window, the second bitmap and the third bitmap.

[0288] In some examples, in a case where the second bitmap indicates to feed back the perceptual measurement result corresponding to R groups of sampling points in the at least one group of sampling points, M bits in the third bitmap can correspond to the R groups of sampling points one by one. M and R are positive integers. The M bits can be part or all of the bits in the third bitmap. Each bit in the M bits can be used to indicate whether to feed back the perceptual measurement result corresponding to the sampling point corresponding to the bit. For example, if a value of a certain bit in the M bits is a fifth value (e.g., 1 or 0), it indicates to feed back the perceptual measurement result of the sampling point corresponding to the bit; if a value of a certain bit in the M bits is a sixth value (e.g., 0 or 1), it indicates not to feed back the perceptual measurement result of the sampling point corresponding to the bit. The fifth value and the sixth value are different.

[0289] Optionally, the M bits can be arranged in a time sequence from front to back of the corresponding sampling points. For example, the at least one sampling window is shown in FIG. 9I, the fifth value is 1, and the sixth value is 0. The second bit map indicates the perception measurement results of the 1st, 4th and 5th groups of sampling points in the feedback sampling window. If the third bit map has a value of 111011, the third bit map indicates that the 1st to 2nd sampling points in the 1st group of sampling points in the feedback sampling window, the 1st sampling point in the 4th group of sampling points in the feedback sampling window, and the 1st to 2nd sampling points in the 5th group of sampling points in the feedback sampling window. Correspondingly, the at least one sampling point includes the 1st to 2nd, 7th, 9th to 10th sampling points in the sampling window. For another example, the at least one sampling window is shown in FIG. 9J, the fifth value is 1, and the sixth value is 0. The second bit map indicates the perception measurement results of the 1st group of sampling points in the feedback sampling window #1 and the 1st to 2nd groups of sampling points in the feedback sampling window #2. If the third bit map has a value of 111011, the third bit map indicates that the 1st to 2nd sampling points in the 1st group of sampling points in the feedback sampling window #1, the 1st sampling point in the 1st group of sampling points in the feedback sampling window #2, and the 1st to 2nd sampling points in the 2nd group of sampling points in the feedback sampling window #2. Correspondingly, the at least one sampling point includes the 1st to 2nd sampling points in the sampling window #1 and the 1st, 3rd to 4th sampling points in the sampling window #2.

[0290] Through the implementation, the first device can accurately determine the at least one sampling window, the second bit map and the third bit map according to the information #1, and accurately determine the at least one sampling point according to the at least one sampling window, the second bit map and the third bit map.

[0291] In addition, in the implementation, the second bit map indicates whether the perception measurement results of each group of sampling points in the at least one group of sampling points are fed back, and in the case where the second bit map indicates that the perception measurement results of the first group of sampling points in the at least one group of sampling points are fed back, the third bit map indicates whether the perception measurement results of each sampling point in the first group of sampling points are fed back. In this way, the first device can not feed back the perception measurement results of all the sampling points in the at least one sampling window, thereby reducing the feedback overhead of the perception measurement results.

[0292] Mode b5: The information #1 includes an index of the at least one sampling point.

[0293] Through the mode, the first device can accurately determine the at least one sampling point according to the information #1. In addition, in the case where the sampling points of which the perception measurement results are to be fed back are sparse, the mode can not indicate whether the perception measurement results of each sampling point are fed back respectively, thereby saving the signaling overhead.

[0294] Optionally, any two of the above manner b1 to manner b5 can be independent or combined with each other.

[0295] In some examples, the manner b2 and the manner b3 can be combined. For example, the information #1 indicates the at least one sampling window and a first bit map. The first bit map indicates whether to feed back the corresponding perception measurement result of the sampling point in the at least one sampling window. The at least one sampling point can include: the sampling point in the sampling point indicated by the first bit map to feed back, the corresponding perception measurement result of which is greater than the first threshold.

[0296] In other examples, the manner b3 and the manner b4 can be combined. For example, the information #1 indicates the at least one sampling window and a second bit map. The second bit map indicates whether to feed back the corresponding perception measurement result of each group of sampling points in the at least one group of sampling points. The at least one sampling point can include: the sampling point in each group of sampling points indicated by the second bit map to feed back, the corresponding perception measurement result of which is greater than the first threshold. For another example, the information #1 indicates the at least one sampling window, the second bit map and a third bit map. The second bit map indicates whether to feed back the corresponding perception measurement result of each group of sampling points in the at least one group of sampling points. In the case that the second bit map indicates to feed back the corresponding perception measurement result of the first group of sampling points in the at least one group of sampling points, the third bit map indicates whether to feed back the corresponding perception measurement result of each sampling point in the first group of sampling points. The at least one sampling point can include: the sampling point in the sampling point indicated by the second bit map and the third bit map to feed back, the corresponding perception measurement result of which is greater than the first threshold.

[0297] In some examples, the manner b2 and the manner b4 can be combined. For example, the second device can determine whether to use the manner b2 or the manner b4 according to a ratio of a number of sampling points for which the sensing measurement result is to be fed back to a number of sampling points in the at least one sampling window and a ratio threshold. In a case that the ratio is less than the ratio threshold, the second device can determine to use the manner b4; and / or in a case that the ratio is greater than or equal to the ratio threshold, the second device can determine to use the manner b2. The number threshold and / or the ratio threshold can be pre-configured, e.g., configured by a protocol, determined by the second device, or indicated by another device, e.g., the first device or a core network device, to the second device. Through the example, the second device can determine whether to use the manner b2 or the manner b4 according to a sparsity of the sampling points for which the sensing measurement result is to be fed back. In a case that the sampling points for which the sensing measurement result is to be fed back are sparse, the second device can determine to use the manner b4; and / or in a case that the sampling points for which the sensing measurement result is to be fed back are dense, the second device can determine to use the manner b2.

[0298] Optionally, in a case that the manner b2 and the manner b4 are combined, the information #1 can further indicate whether to use the manner b2 or the manner b4; or the information #1 can indicate whether to use one-layer bitmap or two-layer bitmap to indicate whether to feed back the sensing measurement result corresponding to the sampling point in the at least one sampling window; or the information #1 can indicate whether the bitmap type is one-layer or two-layer, when the bitmap type is one-layer, the manner b2 is used, and when the bitmap type is two-layer, the manner b4 is used.

[0299] In some possible manners, the information #1 further indicates a sampling frequency of the channel impulse response. The sampling frequency can be related to a bandwidth, e.g., the sampling frequency can be greater than or equal to the bandwidth. The bandwidth can be a bandwidth of the sensing resource. The sensing resource can be a part or all of a bandwidth in a full band, e.g., a bandwidth part (BWP). The sensing resource can overlap with or be independent of a bandwidth of the communication resource.

[0300] Since the sampling frequency of the channel impulse response is related to a time interval between adjacent sampling points of the channel impulse response, the information #1 further indicating the sampling frequency of the channel impulse response can be replaced by (or can be understood as) the information #1 further indicating the time interval between adjacent sampling points of the channel impulse response.

[0301] The manner in which the information #1 indicates the sampling frequency of the channel impulse response can be various, without limitation. In some examples, the information #1 can explicitly indicate the sampling frequency of the channel impulse response. In other examples, the information #1 can implicitly indicate the sampling frequency of the channel impulse response. For example, the information #1 can indicate a time interval between adjacent sampling points of the channel impulse response, and the inverse of the time interval can be the sampling frequency of the channel impulse response. For another example, the information #1 can indicate a distance interval corresponding to adjacent sampling points of the channel impulse response. The distance interval can be used to determine the time interval between adjacent sampling points of the channel impulse response, and thus the sampling frequency of the channel impulse response can be determined. For instance, the time interval between adjacent sampling points of the channel impulse response can be the distance interval divided by the speed of light.

[0302] In this way, the first device can accurately determine the time interval between adjacent sampling points of the channel impulse response according to the sampling frequency of the channel impulse response indicated by the information #1, and thus can accurately determine the time information of the at least one sampling point according to the information #1.

[0303] In other possible manners, the time interval between adjacent sampling points of the channel impulse response can be determined by the first device in a manner without limitation, or can be preset, e.g., specified by a protocol. In this way, the first device can accurately determine the time interval between adjacent sampling points of the channel impulse response, and thus can accurately determine the time information of the at least one sampling point according to the information #1.

[0304] S702: The first device sends the first information; correspondingly, the second device receives the first information.

[0305] The first information can be used to indicate the sensing measurement result, and the indication manner can be various, e.g., one of the manner c1 to the manner c3.

[0306] The manner c1: The first information indicates the first sensing measurement result and the sensing measurement result corresponding to the one or more sampling points outside the sampling window; correspondingly, the second device can determine the first sensing measurement result and the sensing measurement result corresponding to the one or more sampling points according to the first information.

[0307] For example, as shown in FIG. 9K, the sampling point #1 to the sampling point #4 are outside the sampling window, and the sensing measurement results corresponding to the sampling point #1 to the sampling point #4 are the sensing measurement result #1 to the sensing measurement result #4, respectively. The first information can indicate the first sensing measurement result and the sensing measurement result #1 to the sensing measurement result #4.

[0308] It should be understood that FIG. 9K illustrates the one or more sampling points as four sampling points as an example. In actual application, the one or more sampling points can include more or fewer sampling points, without limitation.

[0309] It should also be understood that FIG. 9K illustrates an example in which the first perception measurement corresponds to one sampling window. In actual applications, the first perception measurement can correspond to multiple sampling windows, without limitation.

[0310] The one or more sampling points outside the sampling window include a first sampling point. The specific content of other sampling points in the one or more sampling points can be referred to the description of the first sampling point, and will not be described here.

[0311] The first sampling point can satisfy a second condition, and the second condition includes at least one of the following conditions #b1 to condition #b5:

[0312] Condition #b1: The amplitude of the main lobe corresponding to the first sampling point is greater than or equal to a first amplitude threshold.

[0313] The amplitude of the main lobe corresponding to the first sampling point can be the amplitude of the main lobe of the fourth perception measurement, where the fourth perception measurement is the perception measurement (for example, the channel impulse response) corresponding to the first sampling point; in other words, the amplitude of the main lobe corresponding to the first sampling point can be the amplitude of the peak of the fourth perception measurement. Wherein, the amplitude can be replaced by the intensity.

[0314] The first amplitude threshold can have various forms. For example, the perception measurement can be represented as I+jQ, that is, the perception measurement includes I component information and Q component information; the first amplitude threshold can include an amplitude threshold for the I component information and / or an amplitude threshold for the Q component information. For another example, the perception measurement can be represented as I+jQ, that is, the perception measurement includes I component information and Q component information; the first amplitude threshold can be a common threshold for the I component information and the Q component information. For another example, the perception measurement can be represented as Ae jθ , that is, the perception measurement includes amplitude information and phase information; the first amplitude threshold can be a threshold for the amplitude information.

[0315] Optionally, the first amplitude threshold can be associated with the perception measurement (for example, the channel impulse response information) corresponding to the sampling points in the sampling window; or in other words, the first amplitude threshold can be determined according to the perception measurement (for example, the channel impulse response information) corresponding to the sampling points in the sampling window. For example, the first amplitude threshold can be the average of the peak amplitudes of the channel impulse response information corresponding to the sampling points in the sampling window. For another example, the first amplitude threshold can be the sum of the average of the peak amplitudes of the channel impulse response information corresponding to the sampling points in the sampling window and a first offset. Wherein, the first offset is a positive number, 0 or a negative number. The first offset can be pre-set, for example, specified by a protocol; or can be indicated by another device (for example, a second device or a core network device) to the first device; or can be determined by the first device.

[0316] Still taking FIG. 9K as an example, the sampling point #1 to the sampling point #4 are located outside the sampling window. If the amplitudes of the main lobe corresponding to the sampling point #1 and the sampling point #3 are greater than or equal to the first amplitude threshold, the sampling point #1 and the sampling point #3 satisfy the condition #b1.

[0317] Condition #b2: The interval of the first sampling point to the sampling window is less than or equal to the interval threshold.

[0318] Still taking FIG. 9K as an example, the sampling point #1 to the sampling point #4 are located outside the sampling window. If the intervals of the sampling point #2 and the sampling point #3 to the sampling window are less than or equal to the interval threshold, the sampling point #2 and the sampling point #3 satisfy the condition #b2.

[0319] Condition #b3: The absolute value of the difference between the first transmission delay and the second transmission delay is less than or equal to the delay threshold.

[0320] The first transmission delay is the transmission delay of the perception signal corresponding to the first sampling point. The second transmission delay is the transmission delay of the perception signal corresponding to the sampling point located at the edge of the sampling window. Optionally, the second transmission delay is the transmission delay of the perception signal corresponding to the second sampling point, the second sampling point is located at the edge of the sampling window, and the second sampling point is located at the side of the sampling window close to the first sampling point. For example, as shown in FIG. 9K, if the first sampling point is the sampling point #1 or the sampling point #2, the second sampling point is the first sampling point (hereinafter referred to as the sampling point #5) in the sampling window; if the first sampling point is the sampling point #3 or the sampling point #4, the second sampling point is the last sampling point (hereinafter referred to as the sampling point #6) in the sampling window. Optionally, the edge can also be referred to as the boundary or the margin, etc., and its English translation can also have multiple forms, such as boundary, margin or edge, etc.

[0321] Still taking FIG. 9K as an example, the sampling point #1 to the sampling point #4 are located outside the sampling window. If the absolute value of the difference between the transmission delay of the perception signal corresponding to the sampling point #2 and the transmission delay of the perception signal corresponding to the sampling point #5 is less than or equal to the delay threshold, and the absolute value of the difference between the transmission delay of the perception signal corresponding to the sampling point #3 and the transmission delay of the perception signal corresponding to the sampling point #6 is less than or equal to the delay threshold, the sampling point #2 and the sampling point #3 satisfy the condition #b3.

[0322] Condition #b4: The absolute value of the difference between the first transmission distance and the second transmission distance is less than or equal to the distance threshold.

[0323] The first transmission distance is a transmission distance of the sensing signal corresponding to the first sampling point. The second transmission distance is a transmission distance of the sensing signal corresponding to a sampling point located at an edge of the sampling window. For example, the second transmission distance is a transmission distance of the sensing signal corresponding to a second sampling point, the second sampling point is located at the edge of the sampling window, and the second sampling point is located on a side of the sampling window close to the first sampling point.

[0324] The specific content of condition #b4 can refer to the description of condition #b3, except that the time delay is replaced by the distance, and details are not repeated.

[0325] Condition #b5: the amplitude of the sidelobe corresponding to the first sampling point is greater than or equal to a second amplitude threshold.

[0326] Optionally, the amplitude of the sidelobe corresponding to the first sampling point can be: after superimposing the fourth sensing measurement result and the first sensing measurement result, the amplitude corresponding to the first sampling point, the fourth sensing measurement result is the sensing measurement result (for example, channel impulse response) corresponding to the first sampling point.

[0327] For example, the amplitude of the sidelobe corresponding to the first sampling point can be associated with Asinc(Bτ1), such as the amplitude of the sidelobe corresponding to the first sampling point can be A1sinc(Bτ1); or the amplitude of the sidelobe corresponding to the first sampling point can be the sum of A1sinc(Bτ1) and a second offset. Wherein A1 is the peak amplitude of the main lobe of the fourth sensing measurement result, in other words, A1 is the peak amplitude of the fourth sensing measurement result. The sinc() can be a sinc function, and the expression of the sinc function is sinc(x) = sin(π*x) / π*x, and the sin() can be a sine operator. For example, sinc(Bτ1) = sin(π*Bτ1) / *Bτ1. B is a bandwidth, which can be a bandwidth of a sensing resource. The sensing resource can be part or all of the bandwidth in the full band, for example, it can be a BWP. The sensing resource can overlap or be independent of the bandwidth of the communication resource. τ1 can represent the interval of the first sampling point to the sampling window. Optionally, if the transmission distance of the sensing signal corresponding to the first sampling point is d1, the transmission distance of the sensing signal corresponding to the second sampling point is d2, the second sampling point is located at the edge of the sampling window, and the second sampling point is located on a side of the sampling window close to the first sampling point, then τ1 can be (|d2-d1|) / c, || represents the absolute value operation, and c is the speed of light. The second offset is a positive number, 0 or a negative number. The second offset can be pre-set, for example, specified by a protocol; or can be indicated by another device (for example, a second device or a core network device) to the first device; or can be determined by the first device.

[0328] The second amplitude threshold can have various forms. For example, the sensing measurement result can be expressed as I+jQ, i.e., the sensing measurement result includes I component information and Q component information; the second amplitude threshold can include an amplitude threshold for the I component information and / or an amplitude threshold for the Q component information. For another example, the sensing measurement result can be expressed as I+jQ, i.e., the sensing measurement result includes I component information and Q component information; the second amplitude threshold can be a common threshold for the I component information and the Q component information. For yet another example, the sensing measurement result can be expressed as Ae jθ i.e., the sensing measurement result includes amplitude information and phase information; the second amplitude threshold can be a threshold for the amplitude information.

[0329] Still taking FIG. 9K as an example, the sampling point #1 to the sampling point #4 are located outside the sampling window. If the amplitude of the sidelobe corresponding to the sampling point #3 is greater than or equal to the second amplitude threshold, the sampling point #3 satisfies the condition #b5.

[0330] The second amplitude threshold can have other names, such as a sidelobe threshold, as long as it has the same function, which is within the protection scope of the present application.

[0331] At least one threshold (at least one of the first amplitude threshold, the second amplitude threshold, the interval threshold, the time delay threshold, or the distance threshold) in the condition #b1 to the condition #b5 can be pre-set, for example, specified by a protocol, or indicated to the first device by another device (for example, the second device or a core network device), or determined by the first device.

[0332] For example, the second device can send second information; correspondingly, the first device can receive the second information. The second information can indicate at least one of the first amplitude threshold, the second amplitude threshold, the interval threshold, the time delay threshold, or the distance threshold. In this way, the first device can accurately determine at least one of the above thresholds according to the second information, so as to accurately select the one or more sampling points according to at least one of the above thresholds.

[0333] The second information can be carried in a conventional message (for example, a measurement request or a request sensing information) or in a new message. For example, the second information can be carried in a radio resource control (RRC) message, a medium access control-control element (MAC CE), or downlink control information (DCI).

[0334] The name of the second information can be various, for example, control information, configuration information, indication information, request information, measurement request information, request awareness information, or request positioning information, as long as it has the same function, which is within the protection scope of the present application.

[0335] It should be understood that the second condition can include a combination of one or more of the above-mentioned conditions #b1 to condition #b5, and examples of several combinations are shown below.

[0336] In some examples, the second condition includes condition #b1 and condition #b2. Still taking FIG. 9K as an example, sampling points #1 to #4 are located outside the sampling window. If the amplitudes of the main lobes corresponding to sampling points #1 and #3 are greater than or equal to the first amplitude threshold, and the intervals of sampling points #2 and #3 to the sampling window are less than or equal to the interval threshold, then sampling point #3 satisfies condition #b1 and condition #b2, sampling point #3 can be the first sampling point, or in other words, sampling point #3 can belong to the one or more sampling points.

[0337] In other examples, the second condition includes condition #b1 and condition #b3. Still taking FIG. 9K as an example, sampling points #1 to #4 are located outside the sampling window. If the amplitudes of the main lobes corresponding to sampling points #1 and #3 are greater than or equal to the first amplitude threshold, the absolute value of the difference between the transmission time delay of the awareness signal corresponding to sampling point #2 and the transmission time delay of the awareness signal corresponding to sampling point #5 is less than or equal to the time delay threshold, and the absolute value of the difference between the transmission time delay of the awareness signal corresponding to sampling point #3 and the transmission time delay of the awareness signal corresponding to sampling point #6 is less than or equal to the time delay threshold, then sampling point #3 satisfies condition #b1 and condition #b3, sampling point #3 can be the first sampling point, or in other words, sampling point #3 can belong to the one or more sampling points.

[0338] In yet other examples, the second condition includes condition #b1 and condition #b4. Still taking FIG. 9K as an example, sampling points #1 to #4 are located outside the sampling window. If the amplitudes of the main lobes corresponding to sampling points #1 and #3 are greater than or equal to the first amplitude threshold, the absolute value of the difference between the transmission distance of the awareness signal corresponding to sampling point #2 and the transmission distance of the awareness signal corresponding to sampling point #5 is less than or equal to the distance threshold, and the absolute value of the difference between the transmission distance of the awareness signal corresponding to sampling point #3 and the transmission distance of the awareness signal corresponding to sampling point #6 is less than or equal to the distance threshold, then sampling point #3 satisfies condition #b1 and condition #b4, sampling point #3 can be the first sampling point, or in other words, sampling point #3 can belong to the one or more sampling points.

[0339] In some implementations, the second condition includes which of the conditions #b1 to #b5, can be pre-set, e.g., specified by a protocol; or can be indicated by another device (e.g., the second device or a core network device) to the first device; or can be determined by the first device.

[0340] Optionally, when the second device indicates the second condition to the first device, the indication can be explicit or implicit. For example, the second device can implicitly indicate the second condition by indicating a threshold value. For instance, if the second device sends the second information to the first device, the second information indicating a first amplitude threshold value, it means the second condition includes the condition #b1. For another instance, if the second device sends the second information to the first device, the second information indicating a first amplitude threshold value and a time delay threshold value, it means the second condition includes the condition #b1 and the condition #b3. For yet another instance, if the second device sends the second information to the first device, the second information indicating a first amplitude threshold value and a distance threshold value, it means the second condition includes the condition #b1 and the condition #b4. For yet another instance, if the second device sends the second information to the first device, the second information indicating a second amplitude threshold value, it means the second condition includes the condition #b5.

[0341] In this way, the first device can accurately select the one or more sampling points according to at least one of the conditions #b1 to #b5.

[0342] As mentioned above, the first information can indicate the perception measurement result corresponding to the one or more sampling points outside the sampling window. In some examples, the first information can include the perception measurement result corresponding to the one or more sampling points. In other examples, the first information can indicate a change amount of the perception measurement result corresponding to the one or more sampling points; in other words, the first information can indicate the differential perception measurement result corresponding to the one or more sampling points. For example, the perception measurement result corresponding to the one or more sampling points reported by the first device last time is the perception measurement result #1, and the perception measurement result corresponding to the one or more sampling points to be reported by the first device this time is the perception measurement result #2, the first information can indicate the difference between the perception measurement result #2 and the perception measurement result #1. This example can reduce the transmission overhead of the perception measurement result.

[0343] Optionally, after receiving the first information, the second device can process the first perception measurement result according to the perception measurement result corresponding to one or more sampling points outside the sampling window. For example, the second device can perform a sidelobe interference cancellation processing on the first perception measurement result according to the perception measurement result corresponding to the one or more sampling points. The algorithm of the sidelobe interference cancellation processing is not limited, for example, CLEAN algorithm, space-alternating generalized expectation-maximization (SAGE) algorithm, or compressed sensing algorithm, etc. The sidelobe interference cancellation processing can be replaced by at least one of the following: sidelobe cancellation processing or interference cancellation processing.

[0344] In this way c1, the first information not only indicates the first perception measurement result, but also indicates the perception measurement result corresponding to one or more sampling points outside the sampling window. In this way, the second device can process the first perception measurement result corresponding to the sampling points in the sampling window according to the perception measurement result corresponding to the one or more sampling points, so as to reduce or avoid the influence of the interference on the perception processing in the case that the perception measurement result corresponding to the sampling points outside the sampling window interferes with the perception measurement result corresponding to the sampling points in the sampling window.

[0345] In some possible ways, in the way c1, the first information further indicates point target CIR (channel impulse response) information; that is, in the case that the first information indicates the first perception measurement result and the perception measurement result corresponding to one or more sampling points outside the sampling window, the first information further indicates the point target CIR information. The point target CIR information can also have other names, for example, point target PSF (point spread function) information, etc.

[0346] Optionally, the channel impulse response information of the point target can be a basic unit of channel impulse response information; any multi-target channel impulse response information can be decomposed into superposition of multiple point-target channel impulse response information. For example, FIG. 6B respectively shows channel impulse response information of a sensing signal affected by point 1 and channel impulse response information of a sensing signal affected by point 2, and the two channel impulse response information are point-target channel impulse response information; the multi-target channel impulse response information shown in FIG. 6C can be superposition of the two point-target channel impulse response information shown in FIG. 6B. In this way, in the case that the channel impulse response information corresponding to the sampling point in the sampling window is multi-target channel impulse response information, the second device can decompose the channel impulse response information corresponding to the sampling point in the sampling window according to the channel impulse response information of the point target and the channel impulse response information corresponding to one or more sampling points outside the sampling window, to obtain the point-target channel impulse response information corresponding to the sampling point.

[0347] The first information can indicate the channel impulse response information of the point target in various ways, for example, at least one of the following ways d1 to d3:

[0348] Way d1: the first information includes the channel impulse response information of the actual point target; correspondingly, the second device can determine the channel impulse response information of the actual point target according to the first information.

[0349] For example, the channel impulse response information of the actual point target can include I component information and Q component information of the channel impulse response of the actual point target.

[0350] For another example, the channel impulse response information of the actual point target can include amplitude information and phase information of the channel impulse response of the actual point target.

[0351] Optionally, the channel impulse response information of the actual point target can be understood as Q times oversampled feedback channel impulse response information, where Q is a positive integer.

[0352] In this way d1, the first information can directly include the channel impulse response information of the actual point target. In this way, the second device can accurately determine the channel impulse response information of the actual point target according to the first information. In addition, in this way, the second device does not need to determine the channel impulse response information of the actual point target through additional calculation, thereby reducing the complexity of the second device.

[0353] Way d2: the first information indicates a difference (hereinafter referred to as difference #1) between the channel impulse response information of the actual point target and the channel impulse response information of the ideal point target, and the difference #1 can be used to determine the channel impulse response information of the actual point target; correspondingly, the second device can determine the channel impulse response information of the actual point target according to the difference #1.

[0354] For example, the difference #1 can include a difference between an I component information of the channel impulse response of the actual point target and an I component information of the channel impulse response of the ideal point target, and / or a difference between a Q component information of the channel impulse response of the actual point target and a Q component information of the channel impulse response of the ideal point target.

[0355] For another example, the difference #1 can include a difference between an amplitude information of the channel impulse response of the actual point target and an amplitude information of the channel impulse response of the ideal point target, and / or a difference between a phase information of the channel impulse response of the actual point target and a phase information of the channel impulse response of the ideal point target.

[0356] The form of the channel impulse response information of the ideal point target can be various. The following is an example.

[0357] In some examples, the channel impulse response information of the ideal point target can be expressed by sinc(Bτ2). The sinc() can be a sinc function, and the specific content of the sinc function and B can be referred to the description of the sinc function and B in the condition #b5, which will not be repeated here. When determining the channel impulse response information of a point target corresponding to a sampling point, the sampling point is a center sampling point; τ2 can represent an interval between any sampling point corresponding to the channel impulse response information of the point target and the center sampling point. Optionally, if the transmission distance of the perception signal corresponding to any sampling point is d3, and the transmission distance of the perception signal corresponding to the center sampling point is d4, then τ2 can be (d4-d3) / c, and c is the speed of light.

[0358] In other examples, the channel impulse response information of the ideal point target can be expressed by . Wherein, ∑ represents a continuous addition operation, N represents the number of subcarriers used for perception, exp() represents an exponential function with the natural constant e as the base, and f n The specific content of τ2 can be referred to the description of τ2 in the above paragraph, which will not be repeated here.

[0359] Optionally, before determining the channel impulse response information of the actual point target according to the difference #1, the second device can determine the channel impulse response information of the ideal point target. The channel impulse response information of the ideal point target can be pre-set, for example, specified by a protocol; or can be indicated by another device (for example, the first device or a core network device) to the second device; or can be determined by the second device.

[0360] Through the manner d2, the second device can accurately determine the channel impulse response information of the actual point target according to the first information. In addition, in the manner, the first information can indicate the difference between the channel impulse response information of the actual point target and the channel impulse response information of the ideal point target, and compared with indicating the channel impulse response information of the actual point target, the signaling overhead can be reduced.

[0361] Manner d3: The first information indicates the channel impulse response information of the ideal point target. Correspondingly, the second device can determine the channel impulse response information of the ideal point target as the channel impulse response information of the point target.

[0362] The specific content of the channel impulse response information of the ideal point target can be referred to the description of the channel impulse response information of the ideal point target in the manner d2, and will not be repeated here.

[0363] In some examples, the channel impulse response information of the ideal point target can be represented by sinc(Bτ2). The first information can indicate B. The specific content of sinc(Bτ2) can be referred to the description of sinc(Bτ2) in the manner d2, and will not be repeated here. In this way, the second device can determine the channel impulse response information of the ideal point target according to the first information.

[0364] Through the manner d3, the second device can accurately determine the channel impulse response information of the actual point target according to the first information. In addition, in the manner, the first information can indicate the channel impulse response information of the ideal point target, and compared with indicating the channel impulse response information of the actual point target, the signaling overhead can be reduced.

[0365] The manner in which the first information indicates the channel impulse response information of the point target can be pre-set, for example, specified by a protocol, or indicated by another device (for example, the second device or a core network device) to the first device, or determined by the first device. The manner in which the first information indicates the channel impulse response information of the point target can be understood as (or can be replaced by) at least one of the following: a manner in which the first device feeds back the channel impulse response information of the point target, a mode (or manner) of feeding back the channel impulse response information of the point target, or a mode (or manner) of the channel impulse response information of the point target.

[0366] For example, the second device sends the fourth information; and correspondingly, the first device receives the fourth information. The fourth information can indicate a mode of the channel impulse response information of the feedback point target. The mode of the channel impulse response information of the feedback point target can include at least one of the above-mentioned mode d1 to mode d3. For example, if the fourth information has a value #1 (e.g., 0), it means that the mode of the channel impulse response information of the feedback point target is mode d1; and / or, if the fourth information has a value #2 (e.g., 1), it means that the mode of the channel impulse response information of the feedback point target is mode d2; and / or, if the fourth information has a value #3 (e.g., 2), it means that the mode of the channel impulse response information of the feedback point target is mode d3. The value #1, the value #2 and the value #3 are different from each other.

[0367] The fourth information can be carried in a conventional message (e.g., a measurement request or a request for positioning information) or in a new message. For example, the fourth information can be carried in an RRC message, a MAC CE or a DCI.

[0368] The fourth information can be named in various ways, such as control information, configuration information, indication information, request information, measurement request information, request for awareness information, or request for positioning information, as long as it has the same function, which is within the protection scope of the present application.

[0369] Through this example, the first device can accurately determine the mode of the channel impulse response information of the feedback point target according to the fourth information.

[0370] Mode c2: The first information indicates the second awareness measurement result. Correspondingly, the second device can determine the second awareness measurement result according to the first information.

[0371] The second awareness measurement result can be obtained by processing (e.g., sidelobe interference cancellation processing) the first awareness measurement result according to the awareness measurement result corresponding to part or all of the one or more sampling points outside the sampling window; correspondingly, the first device can process (e.g., sidelobe interference cancellation processing) the first awareness measurement result according to the awareness measurement result corresponding to part or all of the one or more sampling points outside the sampling window to obtain the second measurement result. Alternatively, the second awareness measurement result is obtained by performing sidelobe interference cancellation processing on the first awareness measurement result; correspondingly, the first device can perform sidelobe interference cancellation processing on the first awareness measurement result to obtain the second awareness measurement result. The specific content of the sidelobe interference cancellation processing can be referred to the description of the sidelobe interference cancellation processing in mode c1, which will not be repeated here.

[0372] In this way c2, the first device can indicate the second sensing measurement result to the second device, the second sensing measurement result being obtained by processing the first sensing measurement result according to the sensing measurement results corresponding to part or all of the one or more sampling points outside the sampling window, so that in the case that the sensing measurement results corresponding to the sampling points outside the sampling window interfere with the sensing measurement results corresponding to the sampling points in the sampling window, the influence of the interference on the sensing processing can be reduced or avoided.

[0373] In addition, in this way, the first device can process the first sensing measurement result according to the sensing measurement results corresponding to part or all of the one or more sampling points, and transmit the processed sensing measurement result, so that the processing complexity of the second device can be reduced.

[0374] Optionally, in the way c2, the first information further indicates that the second sensing measurement result is obtained by processing the first sensing measurement result according to the sensing measurement results corresponding to part or all of the one or more sampling points; that is, in the case that the first information indicates the second sensing measurement result, the first information further indicates that the second sensing measurement result is obtained by processing the first sensing measurement result according to the sensing measurement results corresponding to part or all of the one or more sampling points. Or, in the case that the second sensing measurement result is obtained by performing sidelobe interference cancellation processing on the first sensing measurement result, the first information can indicate that the second sensing measurement result is obtained by performing sidelobe interference cancellation processing on the first sensing measurement result. In this way, the second device can accurately determine that the second sensing measurement result is a processed result according to the first information.

[0375] Way c3: the first information indicates the first sensing measurement result. Correspondingly, the second device can determine the first sensing measurement result according to the first information.

[0376] The way in which the first information indicates the sensing measurement result can be pre-set, for example, specified by a protocol, or indicated to the first device by another device (for example, the second device or a core network device), or determined by the first device. Wherein, the way in which the first information indicates the sensing measurement result can be understood as (or replaced by) at least one of the following: the way in which the first device feeds back the sensing measurement result, or the mode (or way) of feeding back the sensing measurement result. Wherein, the mode of feeding back the sensing measurement result can be replaced by at least one of the following: the mode of feeding back the channel impulse response information, or the channel impulse response mode.

[0377] Optionally, the second device transmits third information; and correspondingly, the first device receives the third information. Wherein, the third information indicates the mode (or way) of feeding back the sensing measurement result.

[0378] In some examples, in a case that the third information indicates that the mode of feeding back the awareness measurement result is the first mode, the first information can indicate the first awareness measurement result and the awareness measurement result corresponding to the one or more sampling points, i.e., the first device can feed back the awareness measurement result by the manner c1. For example, if the value of the third information is value #4 (e.g., 2), it indicates that the mode of feeding back the awareness measurement result is the first mode, and the first device feeds back the awareness measurement result by the manner c1.

[0379] In some other examples, in a case that the third information indicates that the mode of feeding back the awareness measurement result is the second mode, the first information indicates the second awareness measurement result, i.e., the first device can feed back the awareness measurement result by the manner c2. For example, if the value of the third information is value #5 (e.g., 1), it indicates that the mode of feeding back the awareness measurement result is the second mode, and the first device can feed back the awareness measurement result by the manner c2.

[0380] In some further examples, in a case that the third information indicates that the mode of feeding back the awareness measurement result is the third mode, the first information indicates the first awareness measurement result, i.e., the first device can feed back the awareness measurement result by the manner c3. For example, if the value of the third information is value #6 (e.g., 0), it indicates that the mode of feeding back the awareness measurement result is the third mode, and the first device can feed back the awareness measurement result by the manner c3.

[0381] In some examples, the value #4, the value #5 and the value #6 are different from each other.

[0382] In some examples, the third information can be carried in a conventional message (e.g., a measurement request or a request positioning information), or can be carried in a new message. For example, the third information can be carried in an RRC message, a MAC CE or a DCI. Any two of the third information, the fourth information and the second information can be carried in the same message, or can be carried in different messages. In a case that any two of the third information, the fourth information and the second information are carried in different messages, the transmission order of the two information is not limited.

[0383] The third information can have various names, such as control information, configuration information, indication information, request information, measurement request information, request awareness information, or request positioning information, as long as it has the same function, which is within the protection scope of the present application.

[0384] By the method, the first device can accurately determine the mode of feeding back the awareness measurement result according to the third information.

[0385] Optionally, in a case that the first condition is met, the first device can send the first information, and correspondingly, the second device receives the first information. The first condition includes at least one of the following conditions #c1 to #c2:

[0386] Condition #c1: the time for periodically sending the perception measurement result arrives.

[0387] Condition #c1 can be understood as: the first device can periodically send the perception measurement result. The sending period can be pre-set, e.g., specified by a protocol; or can be indicated to the first device by another device (e.g., the second device or the core network device); or can be determined by the first device.

[0388] For example, if the period for the first device to send the perception measurement result is 20 milliseconds (ms), and the time for the first device to send the perception measurement result last time is the 5th ms, then at the 25th ms, condition #c1 is satisfied.

[0389] Condition #c2: the change of the perception measurement result corresponding to one or more sampling points outside the sampling window is greater than or equal to a first threshold.

[0390] Optionally, condition #c2 can be understood as at least one of: the differential perception measurement result corresponding to one or more sampling points outside the sampling window is greater than or equal to the first threshold; or the change of the perception measurement result corresponding to one or more sampling points outside the sampling window measured by the first device currently is greater than or equal to the first threshold, compared with the perception measurement result corresponding to one or more sampling points outside the sampling window measured or sent by the first device last time.

[0391] The first threshold can be pre-set, e.g., specified by a protocol; or can be indicated to the first device by another device (e.g., the second device or the core network device); or can be determined by the first device.

[0392] Still taking FIG. 9K as an example, sampling point #1 to sampling point #4 are outside the sampling window. The perception measurement result sent by the first device last time includes the perception measurement result #1 of sampling point #3. The perception measurement result of sampling point #3 measured by the first device currently is the perception measurement result #2. If the difference between the perception measurement result #2 and the perception measurement result #1 is greater than or equal to the first threshold, then condition #c2 is satisfied.

[0393] The first condition is exemplified below.

[0394] In some examples, the first condition includes condition #c1. For example, if the period for the first device to send the perception measurement result is 20 ms, and the time for the first device to send the perception measurement result last time is the 5th ms, then at the 25th ms, the first device can send the first information.

[0395] In some examples, the first condition comprises condition #c2. For example, still taking FIG. 9K as an example, sampling point #1 to sampling point #4 are located outside the sampling window. The last time the first device transmits the perception measurement result comprises the perception measurement result #1 of sampling point #3. The perception measurement result of sampling point #3 currently measured by the first device is the perception measurement result #2. If the difference between the perception measurement result #2 and the perception measurement result #1 is greater than or equal to the first threshold, the first device can transmit the first information.

[0396] In yet some examples, the first condition comprises condition #c1 and condition #c2. For example, the period of the first device transmitting the perception measurement result is 20 ms. The last time the first device transmits the perception measurement result is the 5th ms, and the last time the first device transmits the perception measurement result comprises the perception measurement result #1 of sampling point #3. If at the 25th ms, the perception measurement result of sampling point #3 currently measured by the first device is the perception measurement result #2, and the difference between the perception measurement result #2 and the perception measurement result #1 is greater than or equal to the first threshold, at the 25th ms, the first device can transmit the first information.

[0397] It should be understood that the above-mentioned condition #c1 and condition #c2 are only examples, and the first condition can also comprise other conditions, which are not limited.

[0398] In this way, the first device transmits the first information indicating the perception measurement result only when the first condition is met. Compared with always transmitting the perception measurement result, this way can reduce the transmission overhead of the perception measurement result.

[0399] The first information can be carried in a conventional message (for example, measurement response or provide location information), or can be carried in a new message. For example, the first information can be carried in an RRC message, a MAC CE or uplink control information (UCI).

[0400] The name of the first information can be various, for example, feedback information, response information, measurement response information, provide perception information, or provide location information, as long as it has the same function, it is within the protection scope of the present application.

[0401] S703: The second device performs perception processing according to the first information.

[0402] Optionally, the second device can determine the information of the sensing target in the region of interest according to the sensing measurement result indicated by the first information, and the specific manner of determination is not limited. For example, the information of the sensing target can include at least one of the following: the position of the sensing target, the speed of the sensing target, the distance from the sensing target to the receiving device, the distance from the sensing target to the sending device, the direction of the sensing target, the angle of the sensing target, the strength of the echo signal from the sensing target, etc.

[0403] Through the method shown in FIG. 7, the first device can send the first information to the second device. If the first information indicates the first sensing measurement result and the sensing measurement result corresponding to one or more sampling points outside the sampling window, the second device can process the first sensing measurement result according to the sensing measurement result corresponding to the one or more sampling points, so as to reduce or avoid the influence of the interference caused by the sensing measurement result corresponding to the sampling point outside the sampling window on the sensing measurement result corresponding to the sampling point in the sampling window. If the first information indicates the second sensing measurement result, which is obtained by processing the first sensing measurement result according to the sensing measurement result corresponding to part or all of the one or more sampling points outside the sampling window, the influence of the interference caused by the sensing measurement result corresponding to the sampling point outside the sampling window on the sensing measurement result corresponding to the sampling point in the sampling window can be reduced or avoided.

[0404] In some possible manners, the method shown in FIG. 7 further includes S704:

[0405] S704: The first device sends the capability information; correspondingly, the second device receives the capability information.

[0406] The capability information can indicate whether the first device has at least one of the following capabilities: sidelobe cancelation capability, the capability of feeding back the sensing measurement result corresponding to the sampling point outside the sampling window, or the capability of feeding back the channel impulse response information of the sensing target; or in other words, the capability information can indicate whether the first device can perform at least one of the following operations (or processes): sidelobe cancelation, feeding back the sensing measurement result corresponding to the sampling point outside the sampling window, or feeding back the channel impulse response information of the sensing target.

[0407] The capability information can be referred to as sixth information, capability indication information, operation indication information, or the like, as long as it has the same function and is within the scope of the present application. The first device can be a first apparatus or a device in which the first apparatus is located. The sidelobe cancellation capability can be referred to as a sidelobe interference cancellation capability, an interference cancellation capability, a sidelobe cancellation processing capability, or the like, as long as it has the same function and is within the scope of the present application. The capability of the sensing measurement result corresponding to the sampling point outside the feedback sampling window can be referred to as an additional path feedback capability, as long as it has the same function and is within the scope of the present application. The capability of the channel impulse response information of the feedback point target can be referred to as a point target CIR feedback capability, as long as it has the same function and is within the scope of the present application.

[0408] Optionally, S704 can be performed before S701 and / or S702.

[0409] Optionally, after receiving the capability information, the second apparatus can configure (or indicate) the first apparatus with the mode of feeding back the sensing measurement result according to the capability information.

[0410] In some examples, the capability information indicates that the first device has the sidelobe cancellation capability, in other words, the capability information indicates that the first device is capable of performing the sidelobe cancellation operation. The second apparatus sends third information; correspondingly, the first apparatus receives the third information. The third information indicates that the mode of feeding back the sensing measurement result is the second mode; correspondingly, in S702, the first information can indicate the second sensing measurement result, that is, the first apparatus can feed back the sensing measurement result in the above manner c2.

[0411] In other examples, the capability information indicates that the first device has the capability of feeding back the sensing measurement result corresponding to the sampling point outside the feedback sampling window and the capability of feeding back the channel impulse response information of the feedback point target, in other words, the capability information can indicate that the first device is capable of performing the following operations (or processes): feeding back the sensing measurement result corresponding to the sampling point outside the feedback sampling window and feeding back the channel impulse response information of the feedback point target. The second apparatus sends third information; correspondingly, the first apparatus receives the third information. The third information indicates that the mode of feeding back the sensing measurement result is the first mode; correspondingly, in S702, the first information can indicate the first sensing measurement result and the sensing measurement result corresponding to one or more sampling points, that is, the first apparatus can feed back the sensing measurement result in the above manner c1.

[0412] In some examples, the capability information can indicate that the first device does not have the following capabilities: a capability of sidelobe cancellation, a capability of sensing measurement results corresponding to sampling points outside a feedback sampling window, and a capability of feeding back channel impulse response information of a target of a feedback point; or in other words, the capability information can indicate that the first device is incapable of performing (or processing) the following: sidelobe cancellation, sensing measurement results corresponding to sampling points outside a feedback sampling window, and feeding back channel impulse response information of a target of a feedback point. The second device sends third information; and correspondingly, the first device receives the third information. The third information indicates that the mode of feeding back the sensing measurement results is a third mode; and correspondingly, in S702, the first information can indicate the first sensing measurement result, i.e., the first device can feed back the sensing measurement result in the mode c3.

[0413] In this way, the second device can accurately determine the capability of the first device according to the capability information, and thus can configure the first device with a mode of feeding back the sensing measurement result that is suitable for the capability of the first device.

[0414] Optionally, in the method shown in FIG. 7, the first sensing measurement result can be sensing measurement results corresponding to sampling points in a sampling window obtained by the first device in a time period. For example, in a time period #1, the sampling points in the sampling window include sampling point #1-1 to sampling point #1-3. The sensing measurement results corresponding to the sampling point #1-1 to the sampling point #1-3 are respectively: sensing measurement result #1-1 to sensing measurement result #1-3; and the first sensing measurement result can include the sensing measurement result #1-1 to the sensing measurement result #1-3.

[0415] It should be understood that the first device can obtain sensing measurement results corresponding to sampling points in a sampling window in at least one time period, and feed back the sensing measurement results obtained in each time period by the method shown in FIG. 7. The following will be described in detail.

[0416] In S701, the first device can obtain sensing measurement results corresponding to sampling points in a sampling window in P time periods, respectively, and obtain P sensing measurement results in total. P is a positive integer. The P sensing measurement results can include the first sensing measurement result, and any sensing measurement result other than the first sensing measurement result in the P sensing measurement results can be referred to the first sensing measurement result.

[0417] For example, as shown in FIG. 9L, the i-th time period in the P time periods can be denoted as time period #i, i is an integer taking values from 1 to P. In the time period #i, the sampling points in the sampling window include sampling point #i-1 to sampling point #i-3. The sampling point #i-1 to sampling point #i-3 correspond to the perception measurement results #i-1 to #i-3, respectively. The i-th perception measurement result in the P perception measurement results can include the perception measurement results #i-1 to #i-3.

[0418] It should be understood that the number of sampling points in the sampling window in different time periods can be the same or different. The above example is described by taking the same number as an example.

[0419] In S702, the first device can send P information; correspondingly, the second device can receive the P information. The P information can include the first information in S702. Any information in the P information other than the first information can refer to the first information.

[0420] For example, the i-th information in the P information can indicate the perception measurement result by one of the above manners c1 to c3. In other words, the relationship between the i-th information in the P information and the i-th perception measurement result in the P perception measurement results can refer to one of the manners c1 to c3, with the first information being replaced by the i-th information and the first perception measurement result being replaced by the i-th perception measurement result. The repeated parts will not be described again.

[0421] In this application, at least one information in the P information can indicate the perception measurement result by the manner c1 or the manner c2. Optionally, part of the information in the P information can indicate the perception measurement result by the manner c3.

[0422] For example, the P information can include the first information and the fifth information. In other words, the method shown in FIG. 7 further includes that the first device sends the fifth information; correspondingly, the second device receives the fifth information.

[0423] The fifth information indicates the third perception measurement result. The third perception measurement result is the perception measurement result corresponding to the sampling point in the sampling window, and the time corresponding to the third perception measurement result is different from the time corresponding to the first perception measurement result.

[0424] The time corresponding to the third perception measurement result is different from the time corresponding to the first perception measurement result, which can be understood as at least one of the following: the measurement time corresponding to the third perception measurement result is different from the measurement time corresponding to the first perception measurement result; the sending time of the perception signal corresponding to the third perception measurement result is different from the sending time of the perception signal corresponding to the first perception measurement result; or, the sending time of the third perception measurement result is different from the sending time of the first perception measurement result.

[0425] Optionally, the third perception measurement result corresponds to a time different from the time corresponding to the first perception measurement result, which can be replaced by: the third perception measurement result corresponds to a time period different from the time period corresponding to the first perception measurement result.

[0426] For example, in time period #1, the sending device sends perception signal #1; the sampling points in the sampling window include sampling point #1-1 to sampling point #1-3. The perception measurement results corresponding to sampling point #1-1 to sampling point #1-3 are perception measurement result #1-1 to perception measurement result #1-3, respectively; the first perception measurement result can include perception measurement result #1-1 to perception measurement result #1-3. In time period #2, the sending device sends perception signal #2; the sampling points in the sampling window include sampling point #2-1 to sampling point #2-3. The perception measurement results corresponding to sampling point #2-1 to sampling point #2-3 are perception measurement result #2-1 to perception measurement result #2-3, respectively; the third perception measurement result can include perception measurement result #2-1 to perception measurement result #2-3. In different time periods, the sampling points in the sampling window correspond to different times.

[0427] The fifth information can be carried in a conventional message (for example, a measurement response or a message for providing positioning information) or in a new message. For example, the fifth information can be carried in an RRC message, a MAC CE or UCI. The fifth information and the first information can be carried in the same message or in different messages. In the case where the fifth information and the first information are carried in different messages, the order of S705 and S702 is not limited.

[0428] The fifth information can have various names, for example, feedback information, response information, measurement response information, perception information or positioning information, as long as it has the same function, which is within the protection scope of the present application.

[0429] In this way, the second device can accurately determine the third perception measurement result according to the fifth information.

[0430] In a case that at least one of the P pieces of information indicates the perception measurement result by the manner c1 or the manner c2, the i-th piece of information in the P pieces of information can indicate the perception measurement result by a manner determined according to at least one of the following: 1, whether there is a sampling point outside the sampling window in the time period #i that satisfies the second condition, and specific content of the second condition can refer to the description of the second condition in the manner c1, and will not be described herein again; or 2, whether a change of the perception measurement result corresponding to the sampling point outside the sampling window in the time period #i that satisfies the second condition is greater than or equal to a second threshold. The second threshold can be pre-set, for example, specified by a protocol, or indicated by another device (for example, the second device or a core network device), or determined by the first device.

[0431] In some implementations, in a case that there is a sampling point outside the sampling window in the time period #i that satisfies the second condition, the i-th piece of information in the P pieces of information can indicate the perception measurement result by the manner c1 or the manner c2; and / or, in a case that there is no sampling point outside the sampling window in the time period #i that satisfies the second condition, the i-th piece of information in the P pieces of information can indicate the perception measurement result by the manner c3.

[0432] In some implementations, in a case that there is a sampling point outside the sampling window in the time period #i that satisfies the second condition, the i-th piece of information in the P pieces of information can indicate the perception measurement result by the manner c1 or the manner c2; and / or, in a case that there is no sampling point outside the sampling window in the time period #i that satisfies the second condition, the i-th piece of information in the P pieces of information can indicate the perception measurement result by the manner c3.

[0433] As mentioned before, at least one of the P pieces of information can indicate the perception measurement result by means of c1; in other words, any one of the at least one piece of information can indicate the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window. In this case, the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window can be contained in the same or different messages. In the case that the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window are contained in the same message, after receiving the message, the second device can process the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window, without waiting for other messages, so as to improve the speed of perception processing, and reduce the probability of pairing errors of the perception measurement result corresponding to the sampling point in the sampling window and the perception measurement result corresponding to the sampling point outside the sampling window.

[0434] In some examples, when the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window are contained in the same message, the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window can be indicated by adjacent bits. Table 1 shows a possible example of the P pieces of information.

[0435] Table 1

[0436] It should be understood that Table 1 is only an example, and the new table contents obtained by reasonable deformation or supplement or deletion of the contents in Table 1 all belong to the protection scope of the present application. For example, the P pieces of information can indicate the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window in each time period. For another example, for more or fewer time periods in the P time periods, the P pieces of information can indicate the perception measurement result corresponding to the sampling point in the sampling window, and do not indicate the perception measurement result corresponding to the sampling point outside the sampling window.

[0437] In other examples, when the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window are contained in the same message, the P pieces of information can further indicate a first correspondence relationship, which can be the correspondence relationship between the perception measurement result corresponding to the sampling point in the sampling window, and the perception measurement result corresponding to the sampling point outside the sampling window corresponding to the sampling window.

[0438] For example, the P information can include P bits, where each bit of the P bits is used to indicate whether the P information indicates the perception measurement result corresponding to the sampling point outside the sampling window for the time period corresponding to the bit. For example, if a bit of the P bits has a value #7 (e.g., 1 or 0), it means that the P information indicates the perception measurement result corresponding to the sampling point outside the sampling window for the time period corresponding to the bit; if the bit has a value #8 (e.g., 0 or 1), it means that the P information does not indicate the perception measurement result corresponding to the sampling point outside the sampling window for the time period corresponding to the bit.

[0439] Table 2 shows a possible example of the P information. In Table 2, P is 8, value #7 is 1, and value #8 is 0. For time period #1, time period #3, time period #6, and time period #8 of the P time periods, the P information can indicate the perception measurement result corresponding to the sampling point in the sampling window and the perception measurement result corresponding to the sampling point outside the sampling window; for time period #2, time period #4, time period #5, and time period #7 of the P time periods, the P information can indicate the perception measurement result corresponding to the sampling point in the sampling window.

[0440] Table 2

[0441] It should be understood that Table 2 is only an example, and any new table content obtained by reasonable modification, supplement, or deletion of the content in Table 2 is within the scope of the present application. For example, the value of P can be larger or smaller. For another example, the P information can indicate the perception measurement result corresponding to the sampling point in the sampling window and the perception measurement result corresponding to the sampling point outside the sampling window for each time period. For another example, the P information can indicate the perception measurement result corresponding to the sampling point in the sampling window for more or fewer time periods of the P time periods, and not indicate the perception measurement result corresponding to the sampling point outside the sampling window.

[0442] In some examples, the P pieces of information can further indicate a first correspondence relationship between the perception measurement results corresponding to the sampling points in the sampling window and the perception measurement results corresponding to the sampling points outside the sampling window. For example, for each of the P time periods, the P pieces of information can include, in the perception measurement results corresponding to the sampling points in the sampling window, an index or a timestamp of the time period, and include, in the perception measurement results corresponding to the sampling points outside the sampling window, the index or the timestamp of the time period. In this way, after receiving the P pieces of information, the second device can determine the first correspondence relationship according to the index or the timestamp of the time period.

[0443] The methods shown in FIGS. 10-12 are possible examples of the method shown in FIG. 7, respectively.

[0444] In the method shown in FIG. 10, the terminal can perform the operation of the first device in the method shown in FIG. 7, and the perception management network element can perform the operation of the second device in the method shown in FIG. 7. Optionally, in the method, the perception management network element can perform positioning on the perception target in the region of interest by using a DL-TDOA positioning method.

[0445] In the method shown in FIG. 11, the TRP (including the serving TRP and / or the neighboring TRP) can perform the operation of the first device in the method shown in FIG. 7, and the perception management network element can perform the operation of the second device in the method shown in FIG. 7. Optionally, in the method, the perception management network element can perform positioning on the perception target in the region of interest by using a UL-TDOA positioning method.

[0446] In the method shown in FIG. 12, the terminal and the TRP (including the serving TRP and / or the neighboring TRP) can perform the operation of the first device in the method shown in FIG. 7, and the perception management network element can perform the operation of the second device in the method shown in FIG. 7. Optionally, in the method, the perception management network element can perform positioning on the perception target in the region of interest by using a Multi-RTT positioning method.

[0447] Optionally, in the methods shown in FIGS. 10-12, the TRP can be replaced by other access network devices, for example, can be replaced by a gNB; and / or, the uplink perception signal is, for example, an uplink SRS (UL-SRS) or SRS; and / or, the downlink perception signal is, for example, a downlink PRS (DL-PRS) or PRS.

[0448] Optionally, in the methods shown in FIGS. 10-12, the number of terminals can be one or more, and each terminal can perform the operation of the terminal in the methods shown in FIGS. 10-12.

[0449] As shown in FIG. 10, the method comprises:

[0450] S1001: The awareness management network element and the plurality of TRPs perform TRP information exchange.

[0451] The plurality of TRPs can comprise a serving TRP and a neighbor TRP of the terminal.

[0452] Optionally, the TRP information exchange can be NR Positioning Protocol A (NRPPa) TRP information exchange.

For another example, if the value corresponding to the sidelobe cancellation capability is 0, the value corresponding to the capability of feeding back the sensing measurement result of the sampling point outside the sampling window is 0, and the value corresponding to the capability of feeding back the channel impulse response information of the point target is 0, it indicates that the terminal does not have the sidelobe cancellation capability, does not have the capability of feeding back the sensing measurement result of the sampling point outside the sampling window, and does not have the capability of feeding back the channel impulse response information of the point target.
