[0215] Figure 1a is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1a, the communication system 1100 includes a first device 1101, a second device 1102, a third device 1103, and a fourth device 1104.

[0216] In some embodiments, the first device 1101 is a core network device, such as a core network element, a sensing function element, etc.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0221] In some embodiments, the access network device may consist of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. The CU-DU structure allows the protocol layers of the access network device to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining partial or complete protocol layer functions are distributed in the DU, which is centrally controlled by the CU. However, this is not a limitation. In some embodiments, the access network device may be, for example, a base station or a TRP.

[0226] Sensing technology is a technology that integrates sensing capabilities into communication systems. It can obtain rich environmental information based on the basic network architecture and air interface enhancement design, and realize basic sensing applications by utilizing the characteristics of wireless channels.

[0227] In sensing technology, targets or states in the surrounding environment can be sensed based on radio waves. These radio waves can also be called wireless signals, sensing signals, etc. Specifically, a wireless signal transmitter emits radio waves. During transmission, these waves may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase changes, Doppler shift, and signal strength changes. The wireless signal receiver receives the radio waves and compares them with those emitted by the transmitter, or records historical changes in the radio waves, thereby obtaining information about the reflectors. For example, information such as signal strength, delay, phase changes, and Doppler shift can be collected, processed, and the reflector information can be output. During this process, sensing services can be triggered, modified, or terminated according to business needs, wireless resources can be scheduled for data processing, and reflector information can be made available, etc. Reflectors can also be called targets, such as sensing targets.

[0228] In some embodiments, the information of the reflector may include, for example, coordinate information, such as the coordinates of the reflector relative to the wireless signal transmitter / receiver; speed information, such as the moving speed and direction of the reflector relative to the wireless signal transmitter / receiver; and behavior pattern information, such as the motion information of the reflector (e.g., running, walking, approaching, falling, swinging, etc.), weather information (e.g., rain, snow, etc.), and traffic information (e.g., congestion, accidents, etc.).

[0229] In some embodiments, the wireless signal transmitter may be at least one of the following: a network device (e.g., a base station), a wireless access point, or a terminal device; in some embodiments, the wireless signal receiver may be at least one of the following: a network device (e.g., a base station), a wireless access point, or a terminal device. In some embodiments, the wireless access point may be, for example, a Wi-Fi access point (AP).

[0230] In some embodiments, the wireless signal transmitter and the wireless signal receiver may be the same device or different devices, thus resulting in a variety of different sensing modes.

[0231] Figure 1b is a schematic diagram of the sensing modes provided according to an embodiment of the present disclosure. As shown in Figure 1b, taking the wireless signal transmitter as a terminal device or base station and the wireless signal receiver as a terminal device or base station as an example, the following sensing modes can be included:

[0232] Sensing mode 1: Terminal device A sends a sensing signal and receives the sensing signal. For details, please refer to example (1) in Figure 1b.

[0233] Sensing mode 2: Base station A sends a sensing signal and base station A receives the sensing signal. For details, please refer to example (2) in Figure 1b.

[0234] Sensing mode 3: Base station A sends a sensing signal and terminal device A receives the sensing signal. For details, please refer to example (3) in Figure 1b.

[0235] Sensing mode 4: Base station A sends a sensing signal and base station B receives the sensing signal. For details, please refer to example (4) in Figure 1b.

[0236] Sensing mode 5: Terminal device A sends a sensing signal and base station A receives the sensing signal. For details, please refer to example (5) in Figure 1b.

[0237] Sensing mode 6: Terminal device A sends a sensing signal and terminal device B receives the sensing signal. For details, please refer to example (6) in Figure 1b.

[0238] In some embodiments, if the wireless signal transmitter and the wireless signal receiver are the same device, the corresponding sensing mode belongs to the mono-static sensing mode. For example, in Figure 1b, for sensing mode 1, both the wireless signal transmitter and the wireless signal receiver are terminal device A, and for sensing mode 2, both the wireless signal transmitter and the wireless signal receiver are base station A. Therefore, both sensing mode 1 and sensing mode 2 belong to the mono-static sensing mode.

[0239] In some embodiments, if the wireless signal transmitter and the wireless signal receiver are not the same device, the corresponding sensing mode belongs to a bi-static or multi-static sensing mode. In the example of Figure 1b, sensing modes 3, 4, 5, and 6 all belong to bi-static or multi-static sensing modes.

[0240] In sensing technology, a sensing element (SF) can be introduced to provide sensing services. In some embodiments, the SF can be a core network element; in other embodiments, the functionality of the SF can also be integrated into the access network device. If the SF is a core network element independent of the access network device, the SF and the access network device can communicate in a certain way.

[0241] Figure 1c is a schematic diagram of communication between the SF and the access network device according to an embodiment of the present disclosure. As shown in Figure 1c, the network architecture includes multiple different network elements, such as Policy Control Function (PCF) network elements, Network Exposure Function (NEF) network elements, Application Function (AF) network elements, Access and Mobility Management Function (AMF) network elements, Unified Data Management (UDM) network elements, Network Data Analytics Function (NWDAF) network elements, Location Management Function (LMF) network elements, etc. The terminal device accesses the data network (DN) through the access network device. The architectural relationship between the network elements can be seen in the example of Figure 1c.

[0242] Figure 1c illustrates communication interfaces between different devices, such as interfaces N1, N2, N5, N8, N33, and NS1 to NS6. In the example in Figure 1c, the SF communicates with the access network device through the AMF network element. The data exchanged between the SF and the access network device through the AMF network element can include control plane data and data plane data.

[0243] Figure 1d is a second schematic diagram of communication between SF and access network equipment according to an embodiment of the present disclosure. The network elements included in this network architecture can be seen in the example in Figure 1c, and will not be described again here.

[0244] Figure 1d illustrates communication interfaces between different devices, such as the N1, N2, N5, N8, N33, NS1 to NS8 interfaces, etc. in Figure 1d.

[0245] Figure 1d illustrates a network architecture that separates the control plane and data plane. In this architecture, the SF communicates with the access network devices through the AMF network element to achieve the interaction of control plane data; the SF communicates with the access network devices through the UPF network element to achieve the interaction of data plane data.

[0246] Figure 1e is a schematic diagram of communication between SF and access network equipment according to an embodiment of the present disclosure. The network elements included in this network architecture can be seen in the example in Figure 1c, and will not be described again here.

[0247] Figure 1e illustrates the communication interfaces between different devices, such as the Uu interface, N2 interface, N33 interface, and NS1 to NS4 interfaces. As shown in Figure 1e, the SF can communicate directly with access network devices to exchange control plane and data plane data. In other words, in this network architecture, the SF can communicate with access network devices without going through core network elements.

[0248] In the above embodiments, Figures 1c to 1e illustrate different communication methods between the SF and the access network equipment. In some embodiments, the SF can communicate with the terminal equipment through the access network equipment, thereby realizing data interaction between the SF and the terminal equipment. It is understood that different communication methods between the SF and the access network equipment will result in different communication methods between the SF and the terminal equipment.

[0249] In some embodiments, the SF (Sensitive Detection System) has the following functions: triggering sensing services; terminating sensing services; performing sensing quality of service (QoS) parameter conversion in sensing services; controlling corresponding devices to perform sensing according to the needs of sensing services; efficiently processing sensing measurement data; and providing or distributing sensing results. The sensing QoS parameters may include, for example, information such as sensing service type, sensing service identifier, QoS requirements, and sensing measurement data reporting cycle. In some embodiments, QoS parameter conversion is required to meet the QoS requirements of sensing services. For example, in some cases, it is necessary to send information such as sensing service type, sensing service identifier, QoS requirements, and sensing measurement data reporting cycle to the device performing sensing. If the needs of the sensing service change (e.g., sensing area, data reporting time, QoS requirements), the SF can trigger a modification process to convert the sensing QoS parameters.

[0250] Sensing services refer to services related to sensing targets in the surrounding environment, such as buildings, vehicles, people, etc. The process of performing sensing services may include one or more of the following: the SF selects node devices (e.g., wireless signal transmitters and receivers) to perform the sensing services; the wireless signal transmitter sends a sensing signal; upon encountering a target, the target reflects the sensing signal to obtain an echo signal, which is then received by the wireless signal receiver; the wireless signal receiver measures the sensing signal and / or the echo signal to obtain measurement results; the wireless signal receiver reports the measurement results to the SF; and the SF calculates relevant information about the target based on the measurement results (e.g., the target's location, speed, type, etc.).

[0251] During the execution of sensing services, certain factors may cause the services to be suspended. For example, the target to be sensed may move out of the coverage area of ​​the sensing signal due to a change in location, thus preventing the sensing signal from reaching the target.

[0252] Figure 1f is a schematic diagram of an application scenario provided by an embodiment of this disclosure. Referring to Figure 1f, the node device selected by SF for performing the sensing service includes a wireless signal transmitter and a wireless signal receiver, and the target to be sensed is a vehicle. The example in Figure 1f is an access network device (i.e., TRP1 in Figure 1f) acting as a wireless signal receiver.

[0253] The wireless signal transmitter can be a terminal device, such as the UE in the example in Figure 1f. The UE sends a sensing signal, which is reflected by the vehicle to obtain an echo signal, which is then received by TRP1. The sensing mode corresponding to this scenario is UE-TRP bistatic (UE sends a sensing signal, and TRP1 receives the echo signal of the sensing signal).

[0254] The wireless signal transmitter can be an access network device, such as TRP1 in the example of Figure 1f. TRP1 sends a sensing signal, which is reflected by the vehicle to obtain an echo signal, which is then received by TRP1. The sensing mode corresponding to this scenario is TRP monostatic (TRP1 sends a sensing signal, and TRP1 receives the echo signal of the sensing signal).

[0255] The wireless signal transmitter can be an access network device, such as TRP2 in the example of Figure 1f. TRP2 sends a sensing signal, which is reflected by the vehicle to obtain an echo signal, which is then received by TRP1. The sensing mode corresponding to this scenario is TRP-TRP bistatic (TRP2 sends a sensing signal, and TRP1 receives the echo signal of the sensing signal).

[0256] In some embodiments, if TRP1 is unable to continue performing the sensing service, it is necessary to reselect a node device to perform the sensing service, which may involve a switching of the sensing mode. For example, if the reselected node device to perform the sensing service is TRP2, and TRP2 sends a sensing signal and receives the echo signal of the sensing signal, then the new sensing mode is TRP-TRP bistatic.

[0257] Figure 1g is a schematic diagram of an application scenario provided by an embodiment of this disclosure. Referring to Figure 1g, the node device selected by SF for performing the sensing service includes a wireless signal transmitter and a wireless signal receiver, and the target to be sensed is a vehicle. The example in Figure 1g is a scenario in which the terminal device (i.e., UE1 in Figure 1g) acts as the wireless signal receiver.

[0258] The wireless signal transmitter can be a terminal device, such as the UE in the example in Figure 1g. In this case, UE1 sends a sensing signal, which is reflected by the vehicle to obtain an echo signal, which is then received by UE1. The sensing mode corresponding to this scenario is UE monostatic (UE sends a sensing signal, and UE1 receives the echo signal of the sensing signal).

[0259] The wireless signal transmitter can be an access network device, such as TRP1 in the example of Figure 1g. TRP1 sends a sensing signal, which is reflected by the vehicle to obtain an echo signal, which is then received by UE1. The sensing mode corresponding to this scenario is TRP-UE bistatic (TRP1 sends a sensing signal, and UE1 receives the echo signal of the sensing signal).

[0260] The wireless signal transmitter can be a terminal device, such as UE2 in the example of Figure 1g. UE2 sends a sensing signal, which is reflected by the vehicle to obtain an echo signal, which is then received by UE1. The sensing mode corresponding to this scenario is UE-UE bistatic (UE2 sends a sensing signal, and UE1 receives the echo signal).

[0261] In some embodiments, if UE1 is unable to continue performing the sensing service, it is necessary to reselect a node device to perform the sensing service, which may involve a switching of the sensing mode. For example, if the reselected node devices to perform the sensing service are TRP2 and UE2, and TRP2 sends a sensing signal and UE2 receives the echo signal of the sensing signal, then the new sensing mode is TRP-UE bistatic.

[0262] In some cases, terminal devices or access network devices may be unable to continue performing sensing services. Therefore, embodiments of this disclosure provide a communication method to stop sensing services in a timely manner.

[0263] Figure 2a is an exemplary interactive schematic diagram of a communication method provided in this embodiment of the present disclosure. As shown in Figure 2a, the communication method includes the following steps:

[0264] In step S2101, the second device sends third indication information to the first device, the third indication information indicating at least one device recommended by the second device, the at least one device being a device for performing sensing services; or, the third indication information indicating a device for performing sensing services.

[0265] In some embodiments, the first device may be a sensing network element or a sensing device, such as the SF in the example of FIG2a. The second device is the device currently performing the sensing service, and the second device may be, for example, a terminal device (e.g., UE1 in the example of FIG2a) or an access network device (e.g., TRP1 in the example of FIG2a).

[0266] In some embodiments, the sensing service may be to sense a first target within a certain sensing area, thereby identifying the first target, or to sense information such as the position and speed of the first target.

[0267] In some embodiments, the process of performing a sensing service may include, for example, a wireless signal transmitter sending a first sensing signal; a wireless signal receiver receiving a first echo signal of the first sensing signal, wherein the first echo signal may include, for example, a signal obtained by a first target reflecting the first sensing signal; the wireless signal receiver performing a measurement based on the first echo signal to obtain sensing information of the first target, and so on.

[0268] In some embodiments, the second device is a functional node for performing sensing services. For example, the second device is a device for receiving a first sensing signal and / or a first echo signal, i.e., a wireless signal receiver. For example, in single-site sensing mode, the second device is also used to transmit the first sensing signal.

[0269] In some embodiments, the second device may be unable to continue performing the sensing service. Taking TRP1 as an example, if the first target to be sensed is initially within the signal coverage area of ​​TRP1, and as the first target moves away from the signal coverage area of ​​TRP1, then TRP1 cannot continue performing the sensing service.

[0270] In some embodiments, if the second device needs to stop performing the sensing service, the second device may send a third indication message to the first device. The third indication message indicates at least one device recommended by the second device, which is a device used to perform the sensing service. Accordingly, the first device receives the third indication message sent by the second device and determines the at least one device recommended by the second device based on the third indication message.

[0271] In some embodiments, if the second device needs to stop performing the sensing service, the second device may send a third indication message to the first device, the third indication message indicating the device used to perform the sensing service. Accordingly, the first device receives the third indication message sent by the second device and determines the device used to perform the sensing service based on the third indication message.

[0272] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0273] In step S2102, the first device sends a first instruction message to the second device.

[0274] In some embodiments, after receiving a third indication message, the first device can determine, based on the third indication message, that the second device needs to stop performing the sensing service. Therefore, the first device sends a first indication message to the second device, which instructs the second device to stop performing the sensing service. Correspondingly, the second device receives the first indication message sent by the first device and stops performing the sensing service accordingly.

[0275] In some embodiments, the first device determines to send first instruction information to the second device based on the perception result of the first target.

[0276] In some embodiments, the first device may send the first instruction information to the second device even without the third instruction information.

[0277] In step S2103, the second device stops performing the sensing service according to the first instruction information.

[0278] In some embodiments, the second device stops performing sensing services or stops sensing.

[0279] In some embodiments, stopping the execution of sensing services or stopping sensing includes at least one of the following in 1.1 to 1.5 (the following 1.1 to 1.5 are described using the example of a second device stopping the execution of sensing services or stopping sensing, and do not limit the device that stops the execution of sensing services or stops sensing to a second device):

[0280] 1.1 Stop sending the first sensing signal.

[0281] In some embodiments, if the sensing mode corresponding to the sensing service is a single-site sensing mode, the second device is both a wireless signal transmitter for transmitting the first sensing signal and a wireless signal receiver for receiving the first sensing signal and / or the echo signal of the first sensing signal.

[0282] If the second device is used to send the first sensing signal, then after the second device receives the first instruction information sent by the first device, it stops sending the first sensing signal according to the first instruction information, thereby saving system overhead.

[0283] 1.2 Stop receiving the first sensing signal.

[0284] In some embodiments, the second device acts as a wireless signal receiver to receive the first sensing signal. After receiving the first instruction information sent by the first device, the second device stops receiving the first sensing signal according to the first instruction information.

[0285] 1.3 Stop measuring the first sensing signal.

[0286] In some embodiments, the second device acts as a wireless signal receiver to receive the first sensing signal. The second device can also measure the first sensing signal to obtain measurement results, which may include, for example, the channel impulse response, received power, etc., of the first sensing signal, and may include, for example, the position and velocity of the first target, etc. After receiving a first indication message from the first device, the second device can stop measuring the first sensing signal according to the first indication message.

[0287] 1.4. Stop receiving the first echo signal of the first sensing signal.

[0288] This sensing service is used to sense a first target. During propagation, the first sensing signal may encounter the first target, which can reflect the signal, resulting in a first echo signal. This echo signal is received by a second device. After receiving a first instruction from the first device, the second device can stop receiving the first echo signal based on the instruction.

[0289] 1.5 Stop measuring the first echo signal of the first sensing signal.

[0290] In some embodiments, the second device acts as a wireless signal receiver to receive the first echo signal. The second device can also measure the first echo signal to obtain measurement results, which may include, for example, the channel impulse response, received power, etc., of the first echo signal, and may also include, for example, the position and velocity of the first target. After receiving a first indication message from the first device, the second device can stop measuring the first echo signal according to the first indication message.

[0291] In step S2104, the first device sends a first instruction message to the third device.

[0292] In some embodiments, the third device is the device currently performing the sensing service. The third device may be, for example, a terminal device (e.g., UE2 in the example of FIG. 2a) or an access network device (e.g., TRP2 in the example of FIG. 2a). The third device is used to transmit a first sensing signal. During the execution of the sensing service, the third device transmits the first sensing signal. The first sensing signal encounters a first target during propagation. The first target reflects the first sensing signal to obtain a first echo signal. The second device may receive the first sensing signal and / or the first echo signal.

[0293] In some embodiments, the second device and the third device may be the same device, in which case the sensing mode corresponding to the sensing service is a single-site sensing mode. For example, if both the second device and the third device are UE1, then the sensing mode corresponding to the sensing service is UE monostatic; if both the second device and the third device are TRP1, then the sensing mode corresponding to the sensing service is TRP monostatic.

[0294] In some embodiments, the second device and the third device may be different devices, and the sensing mode corresponding to the sensing service is a multi-site sensing mode. In some embodiments, the third device is the device that performs sensing with the second device. For example, the third device sends a first sensing signal, and the second device receives the first sensing signal sent by the third device or the first echo signal of the first sensing signal. For example, if the second device is UE1 and the third device is UE2 (UE1 and UE2 are two different UEs), then the sensing mode corresponding to this sensing service is UE-UE bistatic, that is, UE1 and UE2 perform sensing; if the second device is UE1 and the third device is TRP1, then the sensing mode corresponding to this sensing service is TRP-UE bistatic, that is, TRP1 sends a first sensing signal, and UE1 receives the first sensing signal sent by TRP1 or the echo signal of the first sensing signal; if the second device is TRP1 and the third device is UE2, then the sensing mode corresponding to this sensing service is UE-TRP bistatic; if the second device is TRP1 and the third device is TRP2, then the sensing mode corresponding to this sensing service is TRP-TRP bistatic, that is, UE2 sends a first sensing signal, and TRP2 receives the first sensing signal sent by UE2 or the first echo signal of the first sensing signal.

[0295] In some embodiments, step S2104 is optional. For example, if the second device and the third device are the same device, then step S2104 does not need to be performed.

[0296] In some embodiments, the first device sends a first instruction message to the third device, the first instruction message being used to instruct the third device to stop performing the sensing service.

[0297] In some embodiments, after receiving a third indication message, the first device can determine, based on the third indication message, that the second device needs to stop performing the sensing service. Therefore, the first device sends a first indication message to the third device, which instructs the third device to stop sending the first sensing signal.

[0298] In step S2105, the third device stops sending the first sensing signal according to the first instruction information.

[0299] Correspondingly, the third device receives the first instruction information sent by the first device and stops sending the first sensing signal according to the first instruction information.

[0300] In step S2106, the second device sends auxiliary information to the fourth device, which is used to assist the fourth device in performing sensing services.

[0301] The fourth device is a new device for performing the sensing service. The fourth device can be, for example, a terminal device (e.g., UE3 in the example of Figure 2a) and / or an access network device (e.g., TRP3 in the example of Figure 2a). During the process of sensing the first target, the fourth device can act as a wireless signal transmitter to send a second sensing signal, and it can also act as a wireless signal receiver to receive the second sensing signal and / or the second echo signal of the second sensing signal. Exemplarily, after the second device and / or the third device stop sensing the first target, the fourth device begins sensing the first target.

[0302] In some embodiments, the fourth device may be selected by the first device. For example, the first device may select the fourth device based on the location of the first target, wherein the first target is within the signal coverage area of ​​the fourth device; for example, the first device may estimate the location that the first target will reach based on the speed and location of the first target, and then select the fourth device based on the location that the first target will reach, and so on.

[0303] In some embodiments, the first device may also receive third indication information sent by the second device and select a fourth device in combination with the third indication information.

[0304] In some embodiments, the third indication information is used to indicate at least one device recommended by the second device, and after receiving the third indication information, the first device may select one of the at least one devices as the fourth device. In some embodiments, the fourth device may be one of the at least one devices recommended by the second device, or it may not be one of the at least one devices recommended by the second device.

[0305] In some embodiments, the third indication information is used to indicate the device performing the sensing service. After receiving the third indication information, the first device can designate the device indicated by the third indication information as the fourth device. In some embodiments, the fourth device may be the device indicated by the third indication information for performing the sensing service, or it may not be the device indicated by the third indication information for performing the sensing service.

[0306] In some embodiments, the first device determines the fourth device based on the perception result of the first target.

[0307] After the first device identifies the fourth device, it can instruct the second device to identify the fourth device. The second device then sends auxiliary information to the fourth device, and the fourth device receives the auxiliary information sent by the second device.

[0308] In some embodiments, the second device may select the fourth device based on the perception results of the first target, such as the location of the first target.

[0309] In some embodiments, the auxiliary information is used for at least one of the following 2.1 to 2.3:

[0310] 2.1 Indicates first configuration information, which is used to configure the fourth device to send the second sensing signal.

[0311] This sensing service is used to sense a first target. During the execution of the sensing service by the fourth device, if the fourth device acts as a wireless signal transmitter, it needs to send a second sensing signal. The second device can send auxiliary information to the fourth device, which instructs the fourth device to send the second sensing signal.

[0312] In some embodiments, the first configuration information may include one or more of the following: the power of the fourth device transmitting the second sensing signal, the transmission direction of the fourth device transmitting the second sensing signal, the resources used by the fourth device to transmit the second sensing signal, the beam direction of the fourth device transmitting the second sensing signal, etc.

[0313] 2.2 Indicates second configuration information, which is used to configure the fourth device to receive the second sensing signal and / or the second echo signal, wherein the second echo signal is the echo signal obtained by the first target reflecting the second sensing signal.

[0314] This sensing service is used to sense a first target. During the execution of the sensing service by the fourth device, if the fourth device acts as a wireless signal receiver, it needs to receive a second sensing signal and / or a second echo signal. The second device can send auxiliary information to the fourth device, which instructs the fourth device to receive second configuration information. This second configuration information is used to configure the fourth device to receive the second sensing signal and / or the second echo signal.

[0315] In some embodiments, the second configuration information may include one or more of the following: the power of the fourth device receiving the second sensing signal, the receiving direction of the fourth device receiving the second sensing signal, the resources used by the fourth device to receive the second sensing signal, the beam direction of the fourth device to receive the second sensing signal, the power of the fourth device receiving the second echo signal, the receiving direction of the fourth device to receive the second echo signal, the resources used by the fourth device to receive the second echo signal, the beam direction of the fourth device to receive the second echo signal, etc.

[0316] 2.3 Detect the first target.

[0317] Since this sensing service is used to sense the first target, the fourth device also needs to detect the first target. In some embodiments, the second device can send auxiliary information to the fourth device, which is used to detect the first target. For example, the auxiliary information includes information such as the size, type, speed, and position of the first target, and the fourth device can be assisted in detecting the first target based on this auxiliary information.

[0318] In some embodiments, the auxiliary information includes at least one of the following 3.1 to 3.6:

[0319] 3.1 The movement speed of the first target.

[0320] The movement speed of the first target can be its speed relative to a reference point, or it can be the absolute speed of the first target. This reference point could be, for example, a second device, a third device, etc. The movement speed of the first target can be its real-time speed or its average speed over a period of time.

[0321] Before the second device needs to cease performing sensing operations, it can obtain the moving speed of the first target by receiving the first echo signal and combining the first echo signal. For example, the second device can determine the flight time by the time the third device sends the first sensing signal and the time it receives the first echo signal, and then determine the position of the first target by combining the flight time. By obtaining the position of the first target at multiple different times using the above method, the moving distance of the first target can be obtained by combining the positions of the first target at multiple times, and then the moving speed of the first target can be obtained by combining the moving distance of the first target with the corresponding moving time.

[0322] 3.2 The direction of movement of the first target.

[0323] The direction of movement of the first target can be the direction of movement of the first target relative to a reference point, or it can be the absolute direction of the first target. The reference point can be any fixed direction. The direction of movement of the first target can be the real-time direction of movement, or it can be the approximate direction of movement of the first target over a period of time.

[0324] Before the second device needs to cease performing sensing services, it can obtain the movement direction of the first target by receiving the first echo signal and combining the transmission direction of the first sensing signal and the reception direction of the first echo signal. Alternatively, the second device can determine the position of the first target at multiple different times by measuring the first sensing signal and / or the first echo signal, thereby determining the movement direction of the first target based on its position at those different times.

[0325] 3.3 The location of the first target.

[0326] The location of the first target can be its position relative to a reference point, or its absolute position. This reference point could be, for example, a second device, a third device, etc. The location of the first target can also be the area where it is located, its latitude and longitude, its coordinates, etc.

[0327] Before the second device needs to cease performing sensing operations, it can determine the location of the first target by receiving the first echo signal and combining the first echo signal. For example, the second device can determine the flight time by the time the third device sends the first sensing signal and the time it receives the first echo signal, and then determine the location of the first target by combining the flight time.

[0328] 3.4. Types of the primary objective.

[0329] The first target is the object to be sensed, which may be, for example, a building, vehicle, person, or other object. In some embodiments, the second device may receive a first echo signal of the first sensing signal, then measure the first echo signal of the first sensing signal, and identify the first target based on the measured data to determine the type of the first target.

[0330] 3.5 The direction in which the fourth device sends the second sensing signal.

[0331] The fourth device is a device subsequently used to perform the sensing service. In some embodiments, the fourth device can act as a wireless signal transmitter to send the second sensing signal.

[0332] For example, the second device can obtain the position of the fourth device and determine the transmission direction of the second sensing signal by combining the position of the fourth device and the position of the first target. For example, the second device can also determine the transmission direction of the second sensing signal by combining the receiving direction of the first echo signal received by the second device and the position of the fourth device. For example, the second device can also determine the transmission direction of the second sensing signal by combining the position of the fourth device and the movement direction of the first target.

[0333] 3.6 The receiving direction of the fourth device for receiving the second echo signal.

[0334] The fourth device is a device subsequently used to perform the sensing service. In some embodiments, the fourth device can be used as a wireless signal transmitter to receive the second echo signal, which is the echo signal obtained by the first target reflecting the second sensing signal.

[0335] For example, the second device can obtain the position of the fourth device and determine the receiving direction of the second echo signal of the fourth device by combining the position of the fourth device with the position of the first target. For example, the second device can also determine the receiving direction of the second echo signal of the fourth device by combining the receiving direction of the first echo signal of the second device with the position of the fourth device. For example, the second device can also determine the receiving direction of the second echo signal of the fourth device by combining the position of the fourth device with the movement direction of the first target.

[0336] In some embodiments, auxiliary information may be used to indicate first configuration information. For example, the auxiliary information may include the movement direction of the first target, which may be used to indicate the transmission direction of the second sensing signal transmitted by the fourth device, the beam direction of the second sensing signal transmitted by the fourth device, and so on. For example, the auxiliary information may include the position of the first target, which may be used to indicate the transmission direction of the second sensing signal transmitted by the fourth device, the beam direction of the second sensing signal transmitted by the fourth device, and so on. For example, the auxiliary information may include the transmission direction of the second sensing signal transmitted by the fourth device, which may be used to indicate the beam direction of the second sensing signal transmitted by the fourth device, and so on.

[0337] In some embodiments, auxiliary information may be used to indicate second configuration information. For example, the auxiliary information may include the movement direction of the first target, which may be used to indicate the receiving direction of the fourth device receiving the second sensing signal and / or the second echo signal, the beam direction of the fourth device receiving the second sensing signal and / or the second echo signal, and so on. For example, the auxiliary information may include the position of the first target, which may be used to indicate the receiving direction of the fourth device receiving the second sensing signal and / or the second echo signal, the beam direction of the fourth device receiving the second sensing signal and / or the second echo signal, and so on. For example, the auxiliary information may include the receiving direction of the fourth device receiving the second echo signal, which may be used to indicate the beam direction of the fourth device receiving the second echo signal, and so on.

[0338] In some embodiments, auxiliary information can be used to detect the first target. For example, the auxiliary information includes the position of the first target, the type of the first target, the moving speed of the first target, the moving direction of the first target, etc., and the fourth device can detect the first target based on the above information.

[0339] Step S2107: The fourth device performs sensing services based on the auxiliary information.

[0340] The fourth device is used subsequently to perform the sensing service. In some embodiments, the fourth device can act as a wireless signal transmitter to send the second sensing signal. The fourth device receives the auxiliary information and sends the second sensing signal according to the first configuration information indicated by the auxiliary information.

[0341] In some embodiments, the fourth device can function as a wireless signal transmitter to receive a second echo signal, which is an echo signal reflected by the first target from the second sensing signal. The fourth device receives the auxiliary information and, according to the second configuration information indicated by the auxiliary information, receives the second sensing signal and / or the second echo signal.

[0342] In some embodiments, the fourth device can detect the first target based on auxiliary information and obtain relevant information about the first target, such as the speed, position, type, etc. of the first target.

[0363] In some embodiments, steps S2202, S2204, and S2206 may be performed in an alternate order or simultaneously. Steps S2201, S2204, S2205, S2206, and S2207 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0364] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0365] Figure 2c is an exemplary interactive schematic diagram of the communication method provided in this embodiment of the present disclosure. As shown in Figure 2c, the communication method includes the following steps:

[0366] Step S2301: The second device sends sensing data to the first device.

[0367] In some embodiments, the first device may be a sensing network element or a sensing device, such as the SF in the example of FIG2c. The second device is the device currently performing the sensing service, and the second device may be, for example, a terminal device (e.g., UE1 in the example of FIG2c) or an access network device (e.g., TRP1 in the example of FIG2c).

[0368] In some embodiments, the sensing service may be to sense a first target within a certain sensing area, thereby identifying the first target, or to sense information such as the position and speed of the first target.

[0369] In some embodiments, the second device is a functional node for performing sensing services. For example, the second device is a device for receiving a first sensing signal and / or a first echo signal, i.e., a wireless signal receiver. For example, in single-site sensing mode, the second device is also used to transmit the first sensing signal.

[0370] In some embodiments, the second device may be unable to continue performing the sensing service. Taking TRP1 as an example, if the first target to be sensed is initially within the signal coverage area of ​​TRP1, and as the first target moves away from the signal coverage area of ​​TRP1, then TRP1 cannot continue performing the sensing service.

[0371] In some embodiments, the second device may send sensing data to the first device, the sensing data including the measurement results of the second device on the first sensing signal, and / or the measurement results of the second device on the first echo signal, wherein the first echo signal is the echo signal of the first sensing signal.

[0372] In some embodiments, the measurement results of the second device on the first sensing signal may include one or more of the following: the channel impulse response of the first sensing signal, the received power of the first sensing signal, the signal strength of the first sensing signal, etc.

[0373] In some embodiments, the measurement results of the second device on the first echo signal may include one or more of the following: the channel impulse response of the first echo signal, the received power of the first echo signal, the signal strength of the first echo signal, the position of the first target, the velocity of the first target, etc.

[0374] In step S2302, the first device sends a first instruction message to the second device.

[0375] In some embodiments, after receiving sensing data, the first device can determine, based on the sensing data, that the second device needs to stop performing the sensing service. For example, if the received power of the first sensing signal is less than or equal to a preset power threshold, or the signal strength of the first sensing signal is less than or equal to a preset strength threshold, then the second device needs to stop performing the sensing service. Similarly, if the received power of the first echo signal is less than or equal to a preset power threshold, or the signal strength of the first echo signal is less than or equal to a preset strength threshold, then the second device needs to stop performing the sensing service.

[0376] Therefore, the first device sends a first instruction message to the second device, which instructs the second device to stop performing the sensing service. Correspondingly, the second device receives the first instruction message from the first device and stops performing the sensing service accordingly.

[0377] In step S2303, the second device stops performing the sensing service according to the first instruction information.

[0378] In some embodiments, optional implementations of step S2303 can be found in optional implementations of step S2103 in FIG2a, and other related parts in the embodiments involved in FIG2a, which will not be repeated here.

[0379] Step S2304: The first device sends a first instruction message to the third device.

[0380] In some embodiments, optional implementations of step S2304 can be found in optional implementations of step S2104 in FIG2a, and other related parts in the embodiments involved in FIG2a, which will not be repeated here.

[0381] In step S2305, the third device stops sending the first sensing signal according to the first instruction information.

[0382] In some embodiments, optional implementations of step S2305 can be found in optional implementations of step S2105 in FIG2a, and other related parts in the embodiments involved in FIG2a, which will not be repeated here.

[0383] In step S2306, the second device sends auxiliary information to the fourth device. The auxiliary information is used to assist the fourth device in performing sensing services.

[0384] In some embodiments, optional implementations of step S2306 can be found in optional implementations of step S2106 in FIG2a, and other related parts in the embodiments involved in FIG2a, which will not be repeated here.

[0385] Step S2307: The fourth device performs sensing services based on the auxiliary information.

[0386] In some embodiments, optional implementations of step S2307 can be found in optional implementations of step S2107 in FIG2a, and other related parts in the embodiments involved in FIG2a, which will not be repeated here.

[0387] The communication method involved in the embodiments of this disclosure may include at least one of steps S2301 to S2307. For example, steps S2301+2302+2303 may be implemented as an independent embodiment, and steps S2301+2302+2303+S2304+S2305 may be implemented as an independent embodiment, but are not limited thereto.

[0388] In some embodiments, steps S2302, S2304, and S2306 may be performed in an alternate order or simultaneously. Steps S2301, S2304, S2305, S2306, and S2307 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0389] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0391] Step S2401: The second device sends sensing data to the first device.

[0441] Figure 2g is an exemplary interactive schematic diagram of a communication method provided in this disclosure. As shown in Figure 2g, the communication method includes the following steps:

[0442] In step S2701, the second device determines that the measurement result of the second device on the first sensing signal is less than or equal to the first threshold; and / or, the measurement result of the second device on the first echo signal is less than or equal to the second threshold, and the first echo signal is the echo signal of the first sensing signal.

[0443] The second device is the device currently performing the sensing service. The second device can be, for example, a terminal device (e.g., UE1 in the example of Figure 2g) or an access network device (e.g., TRP1 in the example of Figure 2g).

[0444] In some embodiments, the sensing service may be to sense a first target within a certain sensing area, thereby identifying the first target, or to sense information such as the position and speed of the first target.

[0445] In some embodiments, the third device is a wireless signal transmitter used to send a first sensing signal. The first sensing signal is reflected by the first target after encountering the first target during transmission, resulting in a first echo signal. The second device can receive the first sensing signal and / or the first echo signal.

[0446] In some embodiments, the second device may measure the received first sensing signal to obtain a measurement result of the second device on the first sensing signal. Then, the second device compares the measurement result of the second device on the first sensing signal with a first threshold. If the measurement result of the second device on the first sensing signal is less than or equal to the first threshold, the second device determines that the sensing service needs to be stopped.

[0447] In some embodiments, the measurement result of the first sensing signal by the second device may include, for example, the signal strength and / or the received signal power of the first sensing signal received by the second device. Correspondingly, the first threshold may include a first signal strength threshold and / or a first received signal power threshold. For example, if the signal strength of the first sensing signal received by the second device is less than or equal to the first signal strength threshold, the second device determines that it needs to stop performing the sensing service. For example, if the received signal power of the first sensing signal received by the second device is less than or equal to the first received signal power threshold, the second device determines that it needs to stop performing the sensing service.

[0448] In some embodiments, the second device may measure the received first echo signal to obtain a measurement result of the second device on the first echo signal. Then, the second device compares the measurement result of the second device on the first echo signal with a second threshold. If the measurement result of the second device on the first echo signal is less than or equal to the second threshold, the second device determines that the sensing service needs to be stopped.

[0449] In some embodiments, the measurement result of the first echo signal by the second device may include, for example, the signal strength and / or the received signal power of the first echo signal received by the second device. Correspondingly, the second threshold may include a second signal strength threshold and / or a second received signal power threshold. For example, if the signal strength of the first echo signal received by the second device is less than or equal to the second signal strength threshold, the second device determines that it needs to stop performing the sensing service. For example, if the received signal power of the first echo signal received by the second device is less than or equal to the second received signal power threshold, the second device determines that it needs to stop performing the sensing service.

[0450] In some embodiments, the first threshold and / or the second threshold are configured by the first device; in some embodiments, the first threshold and / or the second threshold may also be preset thresholds.

[0451] In step S2702, the second device sends a second indication message to the first device, which indicates that the second device has stopped performing the sensing service.

[0452] If the measurement result of the first sensing signal by the second device is less than or equal to the first threshold, the second device determines that the sensing service needs to be stopped.

[0453] If the measurement result of the first echo signal by the second device is less than or equal to the second threshold, the second device determines that the sensing service needs to be stopped.

[0454] Then, the second device sends a second instruction message to the first device. Accordingly, the first device receives the second instruction message sent by the second device, and can determine from the second instruction message that the second device has stopped performing the sensing service.

[0455] In step S2703, the second device sends a second instruction message to the third device. The second instruction message is used to indicate that the second device has stopped performing the sensing service or to indicate that the third device has stopped performing the sensing service.

[0456] If the measurement result of the first sensing signal by the second device is less than or equal to the first threshold, the second device determines that the sensing service needs to be stopped.

[0457] If the measurement result of the first echo signal by the second device is less than or equal to the second threshold, the second device determines that the sensing service needs to be stopped.

[0458] Then, the second device sends a second instruction message to the third device. Accordingly, the third device receives the second instruction message sent by the second device, and can determine from the second instruction message that the second device has stopped performing the sensing service.

[0459] For a description of the third device, please refer to the relevant description of step S2104 in Figure 2a, which will not be repeated here. In some embodiments, step S2703 is optional.

[0504] Option 1: A service continuity sensing method, comprising any one of the following 1-14 (in Option 1, the second device is an access network device, and the first device is a sensing network element):

[0505] 1. The access network device stops sensing, and the stopping of sensing includes:

[0506] The access network device stops sensing based on a signal quality threshold of the received sensing signal or the echo signal of the sensing signal. For example, if the signal quality of the sensing signal or the echo signal of the sensing signal is lower than a certain signal quality threshold, the access network device will stop sensing.

[0507] Access network devices are based on the implementation of stop sensing.

[0508] Stop sensing means stopping receiving / measuring sensing signals, or sensing echo signals.

[0509] 2. Based on 1, the access network device (TRP / gNB / RAN) sends indication information (such as the second indication information in the above embodiment) to the sensing network element. The indication information is used to instruct the access network device to stop sensing.

[0510] 3. The instruction information may also include:

[0511] Error indications may include, for example, an error cause (e.g., the cause in the above embodiment), such as the target moving away from the target or the target not being detected (e.g., the position of the first target in the above embodiment changes, and / or the second device fails to detect the first target).

[0512] 4. Based on 1, the access network device sends a stop instruction to the terminal device. This stop instruction is used to instruct the terminal device to stop sending sensing signals (assuming the current access network device is TRP1, this applies to the terminal device sending sensing signals received by TRP1).

[0513] 5. Based on step 2, the access network device sends a stop indication to the other access network device it is paired with. This stop indication is used to instruct the other access network device to stop sending sensing signals (assuming the current access network device is TRP1 and the other access network device is TRP2, then this step applies to the sensing mode that TRP2 sends and TRP1 receives).

[0514] 6. In contrast to option 2, the sensing network element sends a stop sensing instruction to the access network device, the stop sensing instruction being used by the access network device to stop measuring sensing signals or sensing echo signals.

[0515] 7. Based on 6, the sensing network element also instructs the access network device to stop sending sensing signals (TRP self-transmission and self-reception mode).

[0516] 8. Based on 6, the sensing network element also instructs another TRP paired with the access network device to stop sending sensing signals (assuming the current access network device is TRP1 and the other access network device is TRP2, then this clause applies to the sensing mode in which TRP2 sends and TRP1 receives).

[0517] 9. Based on 6, the sensing network element sends a stop transmitting sensing signal indication to the terminal device; assuming the current access network device is TRP1, this rule applies to the sensing mode transmitted by the terminal device in the TRP1 receiving mode.

[0518] 10. The access network device sends auxiliary information to the sensing network element, the auxiliary information being used by the sensing network element to determine the sensing node;

[0519] 11. Based on 10, the auxiliary information includes:

[0520] Recommended sensing nodes for access network equipment, such as recommended access network equipment (TRP / RAN / gNB);

[0521] The sensing node identified by the access network device, for example, the access network device is identified as a sensing node.

[0522] 12. The access network device sends auxiliary information to the next sensing node, the auxiliary information being used by the sensing node to determine the sensing signal configuration (e.g., the beam direction of the sensing reference signal) and / or to detect the target.

[0523] 13. Compared to 12, the sensing network element sends auxiliary information to the next sensing node, which includes access network equipment and / or terminal equipment. The auxiliary information is used by the next sensing node to determine the configuration of the sensing signal (e.g., the beam direction of the sensing signal) and / or to detect the target.

[0524] 14. The auxiliary information includes any one of the following:

[0525] The target's speed;

[0526] The direction of the target's movement;

[0527] The location of the target;

[0528] Type of target;

[0529] Recommended direction for transmitting sensing signals, such as the direction of the transmission beam;

[0530] Recommended sensing signal, or direction of receiving sensing signal echo, such as the direction of receiving beam.

[0531] The following example illustrates Scheme 1.

Taking SF as the first device, TRP1 as the second device, UE1 or TRP3 as the third device, and TRP2 or UE2 as the fourth device in Figure 3c, the communication method includes the following steps:

[0533] Step 1. TRP1 receives the sensing signal.

[0534] TRP1 is a wireless signal receiver. TRP1 is currently performing sensing, such as receiving sensing signals.

[0535] Step 2. TRP1 sends sensing data (e.g., sensing signal measurement results and / or echo signal measurement results) to SF.

[0536] Measurement results of the sensed signal may include, for example, the received power of the TRP1 and the signal strength of the sensed signal. Measurement results of the echo signal may include, for example, the received power of the TRP1 and the signal strength of the echo signal.

[0537] Step 3. TRP1 sends the sensing node (TRP or UE) recommended by TRP1 to SF.

[0538] The sensing node recommended by TRP1 is at least one device recommended by the second device in the above embodiments.

[0539] Step 4. TRP1 sends the sensing node (TRP or UE) determined by TRP1 to SF.

[0540] The sensing node determined by TRP1 is the device used to perform sensing services as indicated by the third indication information in the above embodiment.

[0541] Step 5. SF sends a stop sensing instruction (i.e., the first instruction information) to TRP1.

[0542] Step 6. SF sends a stop sensing instruction to UE1 (the stop sensing instruction is the first instruction information, and step 6 is for the case where the third device is UE1).

[0543] Step 7. SF sends a stop sensing instruction to TRP3 (the stop sensing instruction is the first instruction information, and step 7 is for the case where the third device is TRP3).

[0544] Step 8. TRP1 stops sensing based on the stop sensing instruction from SF or TRP1 itself.

[0545] For example, TRP1 can stop sensing based on its own implementation, such as by stopping sensing based on the measurement results of the sensing signal and / or the echo signal by TRP1.

[0546] Step 9. TRP1 sends an indication message (i.e., the second indication message) to SF, which indicates that TRP1 has stopped sensing.

[0547] Step 10. TRP1 sends a stop sensing instruction to UE1 (the stop sensing instruction is the second instruction information, and step 10 is for the case where the third device is UE1).

[0548] Step 11. TRP1 sends a stop sensing instruction to TRP3 (the stop sensing instruction is the second instruction information, and step 11 is for the case where the third device is TRP3).

[0549] Step 12. TRP1 sends auxiliary information to TRP2 (Step 12 applies to the case where the fourth device includes TRP2).

[0550] Step 13. TRP1 sends auxiliary information to UE2 (Step 13 is for the case where the fourth device includes UE2).

[0551] Step 14. SF sends auxiliary information to TRP2 (Step 14 applies to the case where the fourth device includes TRP2).

[0552] Step 15. SF sends auxiliary information to UE2 (Step 15 is for the case where the fourth device includes UE2).

[0553] Step 16. TRP2 performs perception based on auxiliary information.

[0554] Step 17. UE2 performs perception based on auxiliary information.

[0556] 1. The terminal device stops sensing, and the stopping of sensing includes:

[0557] Sensing stops based on a signal quality threshold for the received sensing signal or the echo signal of the sensing signal. For example, if the signal quality of the sensing signal or the echo signal of the sensing signal is lower than a certain signal quality threshold, the terminal device will stop sensing.

[0558] Terminal devices are based on the ability to detect stops.

[0559] Stop sensing means stopping receiving / measuring sensing signals, or sensing echo signals.

[0560] 2. Based on 1, the terminal device sends an instruction message (such as the second instruction message in the above embodiment) to the sensing network element. The instruction message is used to instruct the terminal device to stop sensing.

[0561] 3. The instruction information may also include:

[0562] Error indications may include, for example, an error cause (e.g., the cause in the above embodiment), such as the target moving away from the target or the target not being detected (e.g., the position of the first target in the above embodiment changes, and / or the second device fails to detect the first target).

[0563] 4. Based on step 1, the terminal device sends a stop instruction to the access network device. This stop instruction is used to instruct the access network device to stop sending sensing signals (assuming the current terminal device is UE1 and the access network device is TRP1, then this step applies to the sensing mode sent by TRP1 and received by UE1).

[0564] 5. Based on step 2, the terminal device sends a stop instruction to the other terminal device it is paired with. This stop instruction is used to instruct the other terminal device to stop sending sensing signals (assuming the current terminal device is UE1 and the other terminal device is UE2, then this step applies to the sensing mode that UE2 sends to UE1).

[0565] 6. In contrast to option 2, the sensing network element sends a stop sensing instruction to the terminal device, the stop sensing instruction being used by the terminal device to stop measuring the sensing signal or sensing echo signal.

[0566] 7. Based on 6, the sensing network element also instructs the terminal device to stop sending sensing signals (terminal device self-transmission and self-reception mode).

[0567] 8. Based on 6, the sensing network element also instructs another terminal device paired with this terminal device to stop sending sensing signals (assuming the current terminal device is UE1 and the other terminal device is UE2, then this clause applies to the sensing mode sent by UE2 and received by UE1).

[0568] 9. Based on 6, the sensing network element sends a stop transmitting sensing signal indication to the access network device; assuming the access network device is TRP1, this rule applies to the sensing mode received by the TRP1 transmitting terminal device.

[0569] 10. The terminal device sends auxiliary information to the sensing network element, and the auxiliary information is used by the sensing network element to determine the sensing node.

[0570] 11. Based on 10, the auxiliary information includes:

[0571] Recommended sensing nodes for terminal devices, such as recommended access network devices (TRP / RAN / gNB);

[0572] The sensing node identified by the terminal device, for example, the access network device is identified as the sensing node.

[0573] 12. The terminal device sends auxiliary information to the next sensing node, the auxiliary information being used by the sensing node to determine the sensing signal configuration (e.g., the beam direction of the sensing reference signal) and / or to detect the target.

[0574] 13. Compared to 12, the sensing network element sends auxiliary information to the next sensing node, which includes access network equipment and / or terminal equipment. The auxiliary information is used by the next sensing node to determine the configuration of the sensing signal (e.g., the beam direction of the sensing signal) and / or to detect the target.

[0575] 14. The auxiliary information includes any one of the following:

[0576] The target's speed;

[0577] The direction of the target's movement;

[0578] The location of the target;

[0579] Type of target;

[0580] Recommended direction for transmitting sensing signals, such as the direction of the transmission beam;

[0592] Step 5. SF sends a stop sensing instruction (i.e., the first instruction information) to UE1.

[0593] Step 6. SF sends a stop sensing instruction to TRP1 (the stop sensing instruction is the first instruction information, and step 6 is for the case where the third device is TRP1).

[0594] Step 7. SF sends a stop sensing instruction to UE3 (the stop sensing instruction is the first instruction information, and step 7 is for the case where the third device is UE3).

[0595] Step 8. UE1 stops sensing based on the stop sensing instruction from SF or by UE1 itself.

[0596] For example, UE1 can stop sensing based on its own implementation, such as by stopping sensing based on the measurement results of the sensing signal and / or the echo signal.

[0597] Step 9. UE1 sends an indication message (i.e., the second indication message) to SF. The indication message is used to indicate that UE1 has stopped sensing.

[0598] Step 10. UE1 sends a stop sensing instruction to TRP1 (the stop sensing instruction is the second instruction information, and step 10 is for the case where the third device is TRP1).

For example, an apparatus is proposed, which includes units or modules for implementing the steps performed by the terminal device in any of the above methods.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits.

In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
