[0214] The following is an introduction to Integrated Sensing and Communications (ISAC).

[0215] A wireless signal transmitter (hereinafter referred to as the transmitter) emits radio waves, and a wireless signal receiver (hereinafter referred to as the receiver) receives the radio waves. During the transmission of radio waves, the transmission may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and signal strength change. The wireless signal receiver receives the radio waves and compares the transmitted and received signals, or records the historical changes of the received signal, thereby obtaining information about the reflectors (e.g., coordinate information, velocity information, signal strength, and behavioral pattern information). In a wireless network (e.g., a cellular network), the wireless signal transmitter can be at least one of the following: a base station; a wireless access point, such as a Wi-Fi (WiFi) access point (AP); or a terminal.

[0216] The receiver of a wireless signal can be at least one of the following: a base station; a wireless access point; or a terminal.

[0217] The transmitting end of the wireless signal and the receiving end of the wireless signal can be from the same device or different devices.

When the transmitting end of the wireless signal and the receiving end of the wireless signal are not co-sited, this kind of perception mode can be a bi-static sensing mode.

[0219] Generally, wireless perception controlled by a core network element (e.g., SF-C) increases the latency of ISAC services, for example, the latency of ISAC service establishment, the latency of application of ISAC perception results, etc.

[0220] FIG. 2A is an interaction diagram I of a wireless perception method according to an exemplary embodiment. As shown in FIG. 2A, the embodiments of the present disclosure relate to a wireless perception method for a communication system 100, the method comprising:

[0221] S2101: The first terminal sends first information to the first node.

[0222] The communication system can be the communication system shown in FIG. 1. The first terminal is the terminal 101 shown in FIG. 1. The first node can be one of the network devices 102 shown in FIG. 1. In some embodiments, the first node can be an access network node.

Illustratively, the first node can be a current serving base station of the first terminal. Illustratively, the first node can be a node that generates a perception result based on perception data. Illustratively, the first node can be a node that creates a perception task. In some embodiments, the first node can also be a node that currently has an RRC connection established with the first terminal. Illustratively, the first node can be an access network node that currently controls the execution of the perception task.

[0223] In some embodiments, the first terminal sends an access stratum (AS) message to the first node. Illustratively, the AS message can include but is not limited to an RRC message, a MAC layer message, or a physical layer message. The physical layer message includes but is not limited to uplink control information (UCI). Illustratively, the first terminal sends a first perception task request to the first node through RRC dedicated signaling.

[0224] In some embodiments, the first information is used by the first terminal to request the first node to perform a sensing task. The sensing task can be any of the sensing tasks corresponding to the aforementioned wireless technologies. In the embodiments of the present disclosure, the first terminal requests the access network node to perform the sensing task (i.e., sensing service) instead of requesting the core network SF to perform the sensing task, so that the connection setup delay of the sensing task and the delay of obtaining the sensing result can be shortened. Exemplarily, the sensing task can be an ISAC sensing task.

[0225] In some embodiments, the first sensing task request comprises at least one of:

[0226] first information used to indicate a task parameter of the sensing task;

[0227] second information used to indicate a location of the first terminal.

[0228] In some embodiments, the task parameter can be any parameter related to the sensing task requested by the first terminal to perform. If the first node determines to perform the sensing task, the sensing task can be performed according to the task parameter or a task parameter similar to the task parameter.

[0229] In some embodiments, the sensing task is a task related to the location of the first terminal. In this case, the first sensing task request can carry the location information of the first terminal. The location information of the first terminal can be the location information determined by the first terminal through a satellite positioning system or an inertial positioning system. Exemplarily, the location information of the first terminal can comprise latitude and longitude information. Exemplarily, the location information of the first terminal can comprise relative location information of the first terminal with respect to the first node. Exemplarily, the location information of the first terminal can also comprise an area in which the first terminal is currently located in the cell of the first node. For example, the area of a cell can comprise an edge area and / or a center area.

[0230] In some embodiments, the sensing area of the sensing task can be determined according to the location of the first terminal. Exemplarily, the sensing area is centered at the first terminal, and the sensing of the environment in which the first terminal is located is performed. For example, the sensing task can be obstacle sensing, and the sensing is performed on the obstacles around the first terminal when the first terminal moves. For another example, the sensing area can be the first terminal itself, and the sensing is performed on the speed at which the first terminal moves. Of course, the above are only examples, and the specific implementation is not limited to the above examples.

[0231] In some embodiments, the task parameter comprises at least one of:

[0232] a first parameter used to indicate a mode of performing the sensing task;

[0233] a second parameter used to indicate a quality of service (QoS) requirement of the sensing task.

The first sensing data can be sensing data sent by the first node to the first terminal. The first sensing result can be a sensing result sent by the first node to the first terminal.

[0235] In some embodiments, the first sensing data is acquired by performing the sensing task; and the first sensing result is generated according to the first sensing data.

[0236] In some embodiments, the first parameter indicates a sensing mode, which can be any one of the aforementioned mode 1 to mode 6. Illustratively, the sensing mode indicated by the first parameter can be sensing mode 1, sensing mode 2, sensing mode 5 or sensing mode 6 participated by the access network node, to take advantage of the dense deployment feature of the access network node and the capability of the access network node, to provide high-quality sensing service for the first terminal. And wireless sensing is performed by the access network, especially in the case that the first terminal itself does not support wireless sensing, or the current condition of the first terminal is not suitable for wireless sensing. For example, the first terminal supports wireless sensing but the current load rate is high, which can not be suitable for wireless sensing. For another example, the first terminal supports wireless sensing but the current remaining power is low or the power consumption of the current execution of other tasks is greater than a power consumption threshold, in which case the first terminal is not suitable for wireless sensing.

[0237] In some embodiments, the sensing mode indicated by the first parameter can be sensing mode 3, sensing mode 4, sensing mode 5 and sensing mode 6 participated by the first terminal, for example, the first terminal supports wireless sensing and / or the current condition of the first terminal is suitable for wireless sensing, then the first terminal can use the sensing mode participated by the first terminal itself according to the indication of the first parameter.

[0238] In some embodiments, the second parameter can be a QoS requirement of the sensing task. Illustratively, the QoS requirement can include but is not limited to at least one of the following: a latency requirement; a sensing accuracy; a feedback period or a feedback condition of the sensing data; a feedback period or a feedback condition of the sensing result, etc.

[0239] In some embodiments, the third parameter can also be referred to as a feedback parameter. The feedback parameter can indicate a feedback type. For example, the feedback type can be used to indicate that the first terminal requests feedback of the first sensing data or the first sensing result.

[0240] In some embodiments, the third parameter can also indicate a feedback period, which can include a feedback period of the first sensing data and / or a feedback period of the first sensing result.

[0241] In some embodiments, the third parameter can further indicate a feedback event, e.g., the feedback data or feedback result is sent to the first terminal upon detecting the feedback event. For example, for the obstacle detection of a vehicle, the feedback data or feedback result is sent to the first terminal upon detecting an obstacle within a preset distance on the travel route of the vehicle, otherwise, the feedback data or feedback result can not be sent, thereby saving signaling overhead and / or radio resource overhead.

[0242] In some embodiments, the first perception result is generated according to the first perception data. The first perception data is measurement data for wireless perception. Exemplarily, the first perception data can include but is not limited to at least one of the following: delay spread spectrum, Doppler spectrum, micro-Doppler spectrum, angle spectrum, signal strength information, multipath delay, transmission parameter of the perception signal, arrival parameter of the feedback signal generated based on the perception signal, point cloud data, etc. The transmission parameter can include but is not limited to at least one of the following: transmission angle, transmission time, transmission power. The arrival parameter can include but is not limited to at least one of the following: reception angle, reception time, reception power, etc.

[0243] In some embodiments, the task parameter contained in the first perception task request can further include but is not limited to at least one of the following:

[0244] The fourth parameter is used to indicate a perception area, so that the first node does not need to determine the perception area according to the location of the first terminal;

[0245] The fifth parameter is used to indicate a perception target, e.g., if the first terminal is a vehicle-mounted first terminal, the perception target can be a pedestrian, a vehicle, or an obstacle on the road within the perception area; for another example, if the first terminal is a flight first terminal, the flight first terminal needs to perform nutrient spraying for crops, at this time, the perception target can be the coverage area of the crops on the ground.

[0246] S2102: The first node sends a first perception task response to the first terminal.

[0247] In some embodiments, the first node sends the first perception task response to the first terminal according to whether to respond to the perception task requested by the first terminal.

[0248] In some embodiments, the first node determines to respond to the perception task requested by the first terminal, and sends a first perception task response indicating acceptance of the perception task to the first terminal.

[0249] In some embodiments, the first node determines not to respond to the perception task requested by the first terminal, and sends a first perception task response indicating rejection of the perception task to the first terminal.

[0250] In some embodiments, the first node determines whether to respond to the sensing task requested by the first terminal after receiving the first sensing task request without requesting the core network to determine whether to respond to the sensing task requested by the first terminal.

[0251] For example, the first terminal can be subscribed to a sensing service, and the first terminal can obtain authorization information in advance. The first terminal can carry the authorization information in the first sensing task request. The first node determines that the first terminal is authorized to request a sensing task related to the sensing service. The first node sends the first sensing task response to the first terminal without requesting authorization verification from the core network after receiving the first sensing task request.

[0252] In some embodiments, the authorization information of whether the first terminal is authorized to request a sensing task can be carried in the context of the first terminal. In this way, when the first terminal switches to or reselects to the first node, the first node can obtain whether the first terminal is authorized to request a sensing task by obtaining the context of the first terminal. In this case, the first node can determine whether to respond to the sensing task requested by the first terminal according to the authorization information of the first terminal.

[0253] In some other embodiments, the first node can also determine whether to respond to the sensing task requested by the first terminal according to the load status of the first node, the current wireless environment, and / or the importance of the sensing task requested by the first terminal.

[0254] In some other embodiments, the first node can also determine whether to execute the sensing task requested by the first terminal according to the local configuration of the first node.

[0255] In some embodiments, in the case that the first sensing task response indicates to execute the sensing task, the first sensing task response includes at least one of the following:

[0256] a task identifier, used to indicate the sensing task;

[0260] In some embodiments, the task identifier can be temporarily generated by the first node.

[0267] In some embodiments, the task identifier may be generated by sorting one or more of the above identifiers in a certain order. In this embodiment of the disclosure, the task identifier for the sensing task may be a unique identifier, and the method of generating the task identifier is not limited to any of the above methods.

[0268] In some embodiments, the task identifier is a first type identifier or a second type identifier;

[0269] The first type of identifier is generated based on the node identifier of the first node and the task number of the sensing task;

[0270] The second type of identifier is generated based on the node identifier of the first node, the Public Land Mobile Network (PLMN) identifier of the network to which the first node is located, and the task number of the sensing task.

[0271] In this way, upon receiving the task identifier, the first node, PLMN, or the first terminal requesting to execute the sensing task can be identified.

[0272] The perception mode indicated by the mode information is the perception mode determined by the first node.

[0273] In some embodiments, the first node determines the perception mode for performing the perception task based on a first perception task request, its own status information, and / or local policies.

[0275] In some embodiments, the first configuration can comprise one or more of a resource configuration, a trigger event configuration, a feedback type configuration, a data format configuration, etc.

[0276] Illustratively, the resource configuration comprised in the first configuration can be a periodic configuration, a semi-persistent scheduling (SPS) configuration, or a dynamic configuration. Illustratively, the resource configuration can be a SPS configuration or a configured grant (CG) configuration.

[0277] In some embodiments, the resource configuration of the first configuration can be a downlink resource configuration. Illustratively, the downlink resource configuration can be a downlink frequency domain resource configuration and / or a downlink time domain resource configuration.

Illustratively, the second configuration is preferably a CG configuration, such that when the first terminal needs to report its location information, the first terminal can timely send the location information to the first node according to the CG configuration.

[0279] In some embodiments, the second configuration can comprise at least one of the following: a resource configuration for indicating the resource used by the first terminal to send the location information of the first terminal to the first node; a reporting configuration for indicating the period for the first terminal to send the location information of the first terminal to the first node, or the reporting configuration for indicating a trigger event for triggering the first terminal to send the location information of the first terminal to the first node.

Illustratively, the resource configuration can comprise a configuration of a frequency domain location and / or a time domain location for the first terminal to send the location information. Illustratively, the reporting configuration can be used to trigger the first terminal to report the location information. For example, the reporting configuration can configure the first terminal to periodically report the location information of the first terminal. Alternatively, when a change of a location of the first terminal satisfies a first condition, the first terminal reports the changed location information to the first node. Alternatively, when a change of a signal quality between the first terminal and the first node satisfies a second condition, the first terminal reports the changed location information to the first node.

[0284] In some embodiments, the triggering event comprises at least one of:

[0285] The first terminal enters a cell edge area of a first cell, the first cell being a serving cell of the first node accessed by the first terminal;

[0287] A signal quality of the first terminal in the first cell is less than a first threshold;

For another example, it can be determined whether the first terminal is located in the cell edge area of the first cell according to the received signal strength of the signal transmitted by the first node.

[0290] In some embodiments, the cell edge area of the second cell can also be pre-configured, for example, the cell center area or the cell edge area of the second cell can be distinguished according to the distance between the second node.

[0293] Of course, the above examples are merely illustrative, and the specific implementation is not limited to the above examples.

[0294] In some embodiments, S2102 is an optional step. For example, after the first node receives the first sensing task request of the first terminal, it can determine to perform the sensing task and directly start to perform the sensing task. Subsequently, it can inform the first terminal that the sensing task has been started to be performed or has been completed to be performed through the sending of the sensing data or the sensing result.

[0295] S2103: The first node performs the sensing task.

[0296] In some embodiments, the first node performing the sensing task can include, but is not limited to, at least one of the following:

[0297] The first node completely performs the sensing task by itself;

[0298] The first node requests the second node to perform the sensing task;

[0299] The first node schedules at least one second terminal to perform the sensing task.

[0300] Exemplarily, the second node can be a neighboring access network node of the first node. Exemplarily, the second terminal can be a terminal which has established an RRC connection with the first node. The second terminal can be a terminal which is located within the coverage of the first cell of the first node. The second terminal is different from the first terminal. Exemplarily, in some cases, the first terminal can also belong to the second terminal.

[0301] In some embodiments, the first node determines to perform the sensing task requested by the first terminal, and the first node initiates the performance of the sensing task.

[0302] In some embodiments, the first node performing the sensing task can include creating the sensing task, and exemplarily, the creating the sensing task can include: determining a task identifier, allocating sensing resources of the sensing task; and determining a device for performing the sensing task.

[0303] In some embodiments, if the first sensing task response is only used to indicate to the first terminal whether the first node responds to the sensing task requested by the first terminal, S2102 can be performed before S2103 or synchronously with S2103, and if the first sensing task response needs to include the first configuration and / or the second configuration, S2102 can be performed after S2103.

[0304] In some embodiments, the first node performing the sensing task has three ways, and they are as follows respectively:

[0305] The first way is that the first node acts as a signal transmitting end and a signal receiving end of the sensing task;

[0306] The second way is that the second node participates in the performance of the sensing task, and exemplarily, the second node acts as a signal transmitting end and / or a signal receiving end of the sensing task;

[0307] The third way is that at least one second terminal participates in the performance of the sensing task, and exemplarily, the at least one second terminal acts as a signal transmitting end and / or a signal receiving end of the sensing task.

[0308] The first way can be a single sensing way of the first node. The second way can be a single sensing way of the second node, or a joint sensing way of the second node and the first node. The third way can be a joint sensing way of the first node and the second terminal, or a single sensing way of the second terminal.

[0309] In some embodiments,

[0310] The second way indicates that the second node acts as a signal transmitting end and a signal receiving end of the sensing task, or

[0311] The second way indicates that the first node and the second node can both act as a signal transmitting end and a signal receiving end of the sensing task, or

[0312] The second mode indicates that the first node is a signal transmitting end of the sensing task and the second node is a signal receiving end of the sensing task, or

[0313] The second mode indicates that the second node is a signal transmitting end of the sensing task and the first node is a signal receiving end of the sensing task.

[0314] In some embodiments, the first node further comprises, before performing the sensing task, determining a mode of performing the sensing task.

[0315] The first node determines the mode of performing the sensing task comprises:

[0316] The first node determines the mode of performing the sensing task according to at least one of the location information of the first terminal, the QoS indicated by the first sensing task request, the signal quality between the first terminal and the first node, the local configuration of the first node, the load status of the first node, and the load status of the second node.

[0317] For example, the first terminal is located at the edge area of the cell 1 of the first node and is about to enter the edge area of the cell 2 of the second node, and it is determined to adopt the second mode or the third mode.

[0318] For another example, the first terminal is located at the edge area of the cell of the first node and the first node is busy or the second node is idle, and it is determined to adopt the second mode.

[0319] For still another example, the first terminal is located at the central area of the cell 1 of the first node, and it is determined to adopt the first mode.

[0320] For yet another example, the first sensing task request of the first terminal indicates that the accuracy requirement of the sensing result is higher than the first accuracy, and it is determined to adopt the third mode.

[0321] Of course, the above is only an example of determining the mode of performing the sensing task, and the specific implementation is not limited to the above example.

[0322] In some embodiments, if the first mode is adopted to perform the sensing task, S2103 can comprise:

[0323] The first node transmits the sensing signal;

[0324] The first node receives the feedback signal; the feedback signal is generated based on the sensing signal. For example, the feedback signal is a reflected signal, a diffracted signal, or a Doppler frequency shift signal generated by the sensing signal acting on the sensing area or the sensing target.

[0325] As shown in FIG. 2B, the first node performs the sensing task for the first terminal on the vehicle alone. Illustratively, the first node determines a sensing area according to the position of the first terminal on the vehicle. The sensing area can be a certain area in the direction of the first terminal on the vehicle. The first node determines whether there are pedestrians and / or other vehicles in a preset range in the direction of the vehicle by performing the sensing task.

[0326] In this way, the first node obtains the sensing data by sending the sensing signal and receiving the feedback signal. In the first mode, the first sensing data measured by the first node is the first sensing data sent to the first terminal. The sensing result generated by the first node according to the first sensing data is the first sensing result sent to the first terminal.

[0327] In some embodiments, the first node also generates the first sensing result according to the first sensing data. In other embodiments, the first node directly sends the sensing data to the first terminal, and the first terminal generates the sensing result based on its own processing capability.

[0328] In some embodiments, if the second mode is used to perform the sensing task, S2103 can include:

[0329] The first node sends a second sensing task request to the second node.

[0330] The first node receives the second sensing data or the second sensing result returned by the second node, i.e., the first node receives the second sensing task response sent by the second node; illustratively, the second sensing task response can include the second sensing data or the second sensing result of the second node.

[0331] In some embodiments, the second sensing task request is used to request the second node to perform the sensing task, and in the second mode, the second node acts as the signal transmitting end and the signal receiving end of the sensing task.

[0332] In some embodiments, if the second node sends the second sensing data to the first node, the first node can generate the first sensing result according to the second sensing data, or the first node sends the second sensing data to the first terminal as part or all of the first sensing data, and the first terminal generates the third sensing result by itself.

[0333] In some embodiments, the second perception task request can include a fourth configuration, which is configured by the first node and used to configure the perception task execution of the second node. For example, the fourth configuration can include resource configuration, signal configuration, and the like. The resource configuration can be used to configure the time domain resource and / or frequency domain resource of the second node for sending the perception signal and receiving the feedback signal formed based on the perception signal. The signal configuration can be used to configure the period of sending the perception signal by the second node, the duration of one sending, the signal sequence corresponding to the perception signal, and the like.

[0334] As shown in FIG. 2C, the second node performs the perception of the pedestrian or other vehicle as the signal transmitting end and the signal receiving end for the vehicle-mounted first terminal.

[0335] In some embodiments, if the second mode is used to perform the perception task, S2103 can include:

[0336] The first node sends a second perception task request to the second node;

[0337] The first node receives the second perception task response sent by the second node; for example, the second perception task response can include the second perception data or the second perception result of the second node;

[0338] The first node sends the perception signal;

[0339] The first node receives the feedback signal to obtain the perception data of the first node and the perception result of the first node.

[0340] In some embodiments, the first node generates the first perception result in combination with the perception data of the first node and the second perception data of the second node. Alternatively, the first node generates the first perception result provided to the first terminal based on the second perception result of the second node and the perception data of the first node itself. Alternatively, the first node provides the perception data of the first node and the second perception data of the second node as a whole to the first terminal as the first perception data, and the first terminal generates the third perception result according to the first perception data.

[0341] As shown in FIG. 2D, the first node and the second node perform the perception of the pedestrian or other vehicle as the signal transmitting end and the signal receiving end for the vehicle-mounted first terminal.

[0342] In some embodiments, the second perception task request is used to request the second node to perform the perception task.

[0343] In some embodiments, the second perception task request includes at least one of the following:

[0344] The first information is used to indicate the task parameter of the perception task;

[0345] The second information is used to indicate the location information of the first terminal;

[0346] The task identifier is used to identify the sensing task;

[0347] The first indication information is used to indicate that the second node performs the sensing task as a signal transmitter or as a signal receiver.

[0348] In some embodiments, the second sensing task request can further comprise mode information, which is used to indicate the sensing mode of the sensing task selected by the first node. The sensing mode selected by the first node can be one of the sensing modes requested by the first terminal, or a sensing mode selected according to more QoS provided by the first terminal. The first information included in the second sensing task request can be used for the second node to know the task parameters of the sensing task. Exemplarily, the task parameters can include but are not limited to the first parameter, the second parameter and / or the third parameter.

[0349] In some embodiments, the second sensing task request further comprises fourth information.

[0350] The fourth information can be used to indicate the spectrum, time interval and / or sensing area of the wireless sensing performed by the second node, so as to facilitate the second node to easily perform the sensing task.

[0351] In some embodiments, the task identifier can be a task identifier generated or assigned by the aforementioned first node.

[0352] In some embodiments, the second sensing task request can further comprise the location information of the first terminal. If the second sensing task request comprises the location information of the first terminal, the sensing area can be determined by the second node according to the location information of the first terminal.

[0353] In some embodiments, the second sensing task request can further comprise a movement parameter of the first terminal, which can indicate the moving direction and / or moving speed of the first terminal, so as to facilitate the second node to determine the sensing area by itself.

[0354] In some embodiments, the second node can further comprise a first terminal identifier of the first terminal, so as to facilitate the second node to determine which first terminal requests the current sensing task.

[0355] In some embodiments, when the second sensing task response indicates that the second node performs the sensing task, the second sensing task response comprises at least one of:

[0356] The task identifier is used to identify the sensing task;

[0357] The mode information is used to indicate the mode of performing the sensing task;

[0358] a third configuration for configuring transmission of the second sensing data or the second sensing result; the second sensing data is obtained by the second node performing the sensing task, and the second sensing data or the second sensing result is used by the first node to generate the first sensing result sent to the first terminal; or the second sensing data is used by the first node to obtain the first sensing data sent to the first terminal.

[0359] In some embodiments, the second sensing data and / or the second sensing result can be sent by the second node to the first node as a component of the second sensing task response, or the second sensing data and / or the second sensing result can not be included in the second sensing task response. For example, after receiving the second sensing task request, the second node sends the second sensing task response to the first node according to whether the sensing task is performed. If the second node determines to perform the sensing task, the second node sends the second sensing data and / or the second sensing result to the first node according to the execution status of the sensing task after sending the second sensing task response.

[0360] In some embodiments, the second sensing task response includes a task identifier, which can facilitate the first node to distinguish different sensing tasks when there are multiple sensing tasks.

[0361] In some embodiments, the mode of performing the sensing task by the second node can be determined by the first node or the second node. For example, the first node can indicate the mode of performing the sensing task in the second sensing task request according to the alternative sensing mode suggested by the first terminal, the alternative sensing mode suggested by the first node itself, or the like. For another example, the second sensing task request can not indicate the mode of performing the sensing task, and the mode of performing the sensing task can be determined by the second node according to the location information of the first terminal, the QoS requirement, the local configuration of the second node, or the current status of the second node, or the like.

[0362] In some embodiments, the second sensing task response can further include a third configuration.

[0363] In some embodiments, the third configuration is used for configuring transmission of the second sensing data or the second sensing result. For example, the sensing data of the second node is obtained by the second node performing the sensing task. For another example, the sensing result is generated by the second node according to the sensing data of the second node.

[0364] In some embodiments, the third configuration can include but is not limited to at least one of the following:

[0365] a resource configuration for the second node to send the second sensing data or the second sensing result to the first node;

[0366] The event configuration triggers the second node to send the second sensing data or the second sensing result to the first node. Exemplarily, the target object is detected, and the second sensing data or the second sensing result is sent to the first node.

[0367] In some embodiments, when the wireless sensing is performed in the second mode, the first node can also send a second sensing task request to the second node, requesting the second node to be a signal transmitting end of the sensing task and the first node to be a signal receiving end of the sensing task. Alternatively, when the wireless sensing is performed in the second mode, the first node can also send a second sensing task request to the second node, requesting the second node to be a signal receiving end of the sensing task and the first node to be a signal transmitting end of the sensing task.

[0368] As shown in FIG. 2E, the wireless sensing in the second mode is exemplarily shown. At this time, the second node can be a signal transmitting end and a signal receiving end of the sensing task, or the second node is a signal receiving end of the sensing task and the first node is a signal transmitting end of the sensing task. The second node obtains the second sensing data by sensing itself, and performs compression and other related processing on the second sensing data, so as to return the compressed second sensing data or the second sensing result to the first node.

[0369] In some embodiments, the third mode indicates that the first node is a signal transmitting end of the sensing task and the at least one second terminal is a signal receiving end of the sensing task; or,

[0390] Of course, the above is only an example, and the specific implementation is not limited to the above example.

[0391] S2104: The first node sends the first sensing data or the first sensing result to the first terminal.

[0392] In some embodiments, the first node determines to send the first sensing data or the first sensing result to the first terminal according to the first sensing task request.

[0393] In some embodiments, the first node determines to send the first sensing data or the first sensing result to the first terminal according to the capability of the first terminal. For example, the first terminal has the capability of processing the sensing data, and it is determined to send the first sensing data or the first sensing result to the first terminal. For another example, the first terminal does not have the capability of processing the sensing data or the current state of the first terminal does not meet the condition of processing the sensing data, and it is determined to send the first sensing result to the first terminal.

[0394] In other embodiments, the first node can also determine to send the sensing data or the sensing result to the first terminal according to the status of the first node and / or the local configuration.

[0395] In some embodiments, the first node periodically sends the first sensing data or the first sensing result to the first terminal according to the first sensing task request.

[0398] In some embodiments, the first node sends the third information to the third node after the end of the execution of the perception task.

[0399] In some embodiments, the first node sends the third information to the third node after the end of the execution of the perception task by itself. For example, taking the vehicle-mounted first terminal as an example, the vehicle-mounted first terminal moves quickly between different cells, the execution of the perception task is controlled by the first node when the vehicle-mounted first terminal is located in the first cell, the execution of the perception task is controlled by the second node when the vehicle-mounted first terminal moves to the second cell, and then the first node controls the end of the execution of the perception task.

[0400] In some embodiments, the third node can be an SF or a Charging Data Function (CDF).

[0401] In some embodiments, the third information is used for charging of the perception task by the third node.

[0402] In some embodiments, the third information can include any information that can be used by the third node for charging.

[0403] In some embodiments, the third information can be referred to as Charging Assitance Information.

[0404] In some embodiments, as shown in FIG. 2B, FIG. 2C or FIG. 2D, the first node is the control node of the perception task, the creation node or the node that establishes an RRC connection with the vehicle-mounted first terminal, and the first node sends the third information to the SF-C of the core network, regardless of the first mode, the second mode or the third mode for executing the perception task.

[0405] In some embodiments, the third information can include but is not limited to at least one of the following:

[0406] The first terminal identifier is used to indicate the first terminal.

[0407] The task execution information is used to indicate the execution status related to charging of the perception task.

[0408] The first terminal identifier is included in the third information, which facilitates the third node to know the charging object.

[0409] In some embodiments, the task execution information is used for the third node to determine the charging parameter.

[0410] In some embodiments, the task execution information at least includes time length information used to indicate the execution time length of the perception task.

[0411] For example, when the charging is based on the execution duration, the task execution information can comprise at least duration information. For another example, when the charging is related to the sensing mode, the task execution information can comprise mode information indicating the sensing mode used for executing the current sensing task. For yet another example, when the charging is related to the number of access network nodes participating in the sensing or the traffic, the task execution information can further comprise the number of access network nodes participating in the wireless sensing and / or the traffic data, etc.

[0412] S2106: The third node sends fourth information to the first node.

[0413] In some embodiments, the third node sends the fourth information to the first node after receiving the third information.

[0414] In some embodiments, the fourth information is used to indicate that the third node receives the third information.

[0415] In some embodiments, the fourth information can further comprise charging information. Exemplarily, the charging information can indicate charging condition and / or charging result.

[0416] In some embodiments, the term “information” can be mutually replaced with the terms “message”, “signal”, “signaling”, “report”, “configuration”, “indication”, “instruction”, “command”, “channel”, “parameter”, “field”, “data”, etc.

[0417] In some embodiments, “acquire”, “obtain”, “get”, “receive”, “transmit”, “bidirectional transmission”, “send and / or receive” can be mutually replaced, which can be interpreted as receiving from other subjects, acquiring from protocols, acquiring from higher layers, obtaining by self-processing, autonomously implementing, etc. Protocols, for example, include at least one of 3GPP protocols, Wi-Fi protocols, audio and / or video protocols.

[0418] In some embodiments, the term “send” can be mutually replaced with the terms “transmit”, “report”, “transmit”, etc.

[0419] The wireless sensing method related to the embodiments of the present disclosure can include at least one of S2101-S2106. For example, any one of S2101-S2106 can be implemented as an independent embodiment. For example, after the first terminal sends the first sensing task request to the first node, the first node can not respond to the first terminal, and at this time, S2101 will be implemented as a separate embodiment. For example, S2102 is an optional step. For example, after the first node receives the first sensing task request, the first node can directly start the execution of the sensing task without specifically returning the first sensing task response to the first terminal. For example, the duration of the sensing task is very short, and there is immediate sensing data or sensing result, and at this time, the first sensing task response is not sent, unnecessary signaling overhead is reduced, and the sensing data or sensing result is directly sent to the first terminal.

[0420] In some embodiments, S2103 can be performed in various ways. For example, the first node performs the sensing task alone, the second node performs the sensing task alone, or the first node and the second node jointly perform the sensing task. It is worth noting that S2103 is also an optional step. For example, if the first node refuses to perform the sensing task, S2103 does not need to be performed.

[0421] In some embodiments, the first node can determine whether the first terminal has the capability of wireless sensing according to the type of the first terminal. At this time, the first terminal does not need to report the fourth information, and the first node will know whether the first terminal supports wireless sensing, so S2101 is also an optional step.

[0422] In some embodiments, S2103 and S2104 are also optional steps. For example, after the first core network node receives the fifth information, there is no need for wireless sensing, or there is no need for the first terminal to participate in wireless sensing, and at this time, S2103 and S2104 can be omitted.

[0423] In some embodiments, S2105 can also be an optional step. For example, some types of first terminals have a monthly sensing task fee, and at this time, the core network can inform the first node of the subscription information through the context of the first terminal. At this time, the first node does not need to send the third information for charging to the third node even if it needs to perform the sensing task, thereby saving unnecessary signaling overhead, and therefore S2105 is also an optional step.

[0424] As shown in FIG. 3, the embodiments of the present disclosure provide a wireless sensing method, which is performed by a first node, and the method can include:

[0425] S3101: receiving a first sensing task request.

[0426] In some embodiments, the first node receives the first sensing task request sent by the first terminal.

[0427] In some embodiments, the related description of the first perception task request can be referred to the related description of the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0433] It is worth noting that S3102 and S3103 can have no certain sequence, S3102 can be executed first and then S3103 can be executed, S3102 and S3103 can be executed synchronously, or S3103 can be executed first and then S3102 can be executed.

[0434] S3104: sending the first perception data or the first perception result.

[0435] In some embodiments, the related description of the first perception data or the first perception result can be referred to the corresponding embodiments of FIG. 2A.

[0438] In some embodiments, the first node sends the third information to the third node.

[0439] In some embodiments, the related description of the third information can be referred to the corresponding embodiments of FIG. 2A.

[0440] In some embodiments, the term "information" can be mutually replaced with the terms "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", and the like.

[0441] In some embodiments, "acquire", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be mutually replaced, which can be interpreted as receiving from other subjects, acquiring from protocols, acquiring from higher layers, obtaining by self-processing, autonomously implementing, and the like. The protocols include at least one of 3GPP protocols, Wi-Fi protocols, audio and / or video protocols.

[0442] In some embodiments, the term "send" can be mutually replaced with the terms "transmit", "report", "transmit", and the like.

[0443] The wireless sensing method related to the embodiments of the present disclosure can include at least one of S3101-S2104. For example, any one of S3101 to S3104 can be implemented as an independent embodiment. For example, after the first terminal sends the first sensing task request to the first node, the first node can not respond to the first terminal, and at this time S3101 will be an independent embodiment. Exemplarily, S3102 is an optional step, for example, after the first node receives the first sensing task request, the first node directly starts the execution of the sensing task without specifically returning the first sensing task response to the first terminal. For example, the duration of the sensing task is very short, and there will be sensing data or sensing results immediately, at this time, the first sensing task response is not sent, unnecessary signaling overhead is reduced, and the sensing data or sensing result is directly sent to the first terminal.

[0444] In some embodiments, S3103 can be performed in various ways, for example, the first node performs the sensing task alone, the second node performs the sensing task alone, or the first node and the second node jointly perform the sensing task. It is worth noting that S3103 is also an optional step, for example, in the case where the first node refuses to perform the sensing task, S3103 does not need to be performed.

[0445] In some embodiments, the first node can determine whether the first terminal has the capability of wireless sensing according to the type of the first terminal, at this time the first terminal does not need to report the fourth information, and the first node will also know whether the first terminal supports wireless sensing, so S2101 is also an optional step.

[0446] In some embodiments, S3103 and S3104 are also optional steps, for example, after the first core network node receives the fifth information, but there is no need for wireless sensing, or there is no need for wireless sensing that requires the participation of the first terminal, at this time S3103 and S3104 can be omitted.

[0447] In some embodiments, S3105 can also be an optional step, for example, some types of first terminals have a monthly subscription sensing task fee, at this time the core network can inform the first node of this subscription information through the context of the first terminal and the like. At this time, even if the first node needs to perform a sensing task, it does not need to send the third information for charging to the third node, thereby saving unnecessary signaling overhead, so S3105 is also an optional step.

[0448] As shown in FIG. 4, the embodiments of the present disclosure provide a wireless sensing method, which can be executed by a second node, and the method can include:

[0449] S4101: receiving a second sensing task request.

[0450] In some embodiments, the second node receives the second sensing task request sent by the first node.

[0451] In some embodiments, the second sensing task request is used for the second node to perform a sensing task.

[0452] In some embodiments, the second sensing task request includes at least one of the following:

[0453] The first information is used to indicate the task parameters of the sensing task;

[0454] The second information is used to indicate the location information of the user equipment first terminal;

[0455] The task identifier is used to identify the sensing task.

[0456] In some example embodiments, the related description of the second sensing task request can refer to the corresponding description of FIG. 2A.

[0457] S4102: sending a second sensing task response.

[0458] In some embodiments, the second node sends the second sensing task response to the first node.

[0459] In some embodiments, the second sensing task response is used to indicate whether the second node performs the sensing task.

[0460] In some embodiments, the second perception task response indicates the second node to perform the perception task, and the second perception task response comprises at least one of the following: a task identifier for indicating the perception task; mode information for indicating a mode of performing the perception task.

[0461] In some embodiments, the second perception task response can refer to the description of FIG. 2A.

[0462] S4103: sending the second perception data or the second perception result.

[0463] In some embodiments, the second node sends the second perception data or the second perception result to the first node.

[0464] In some embodiments, the second perception data is generated by the second node performing the perception task.

[0465] In some embodiments, the second perception result is generated according to the second perception data.

[0466] In some embodiments, before sending the second perception data or the second perception result, the second node sends a perception signal according to the second perception task request and / or receives a feedback signal generated based on the perception signal. For example, the feedback signal can be based on the perception signal sent by the first node and / or the feedback signal formed based on the perception signal sent by the second node.

[0467] Exemplarily, the first node and the second node can interact information based on an air interface between base stations, a backhaul link, a tunnel, or a service base interface (SBI), for example, to transmit one or more of the second perception task request, the second perception task response, the second perception data, and the second perception result.

[0468] In some embodiments, the second perception data and / or the second perception result can be carried in the second perception task response and sent to the first node. Alternatively, the second node sending the second perception task response is an optional operation. After receiving the second perception task request, since the first node and the second node both belong to access network nodes, they can be considered as mutually trusted nodes. The second node can start to perform the perception task after receiving the second perception task request, and send the second perception data and / or the second perception result to the first node when the second perception data and / or the second perception result are obtained, and thus the reception of the first perception task response can be omitted.

[0469] In some embodiments, the term “information” can be mutually replaceable with the terms “message”, “signal”, “signaling”, “report”, “configuration”, “indication”, “instruction”, “command”, “channel”, “parameter”, “field”, “data”, and the like.

[0470] In some embodiments, “acquire”, “obtain”, “get”, “receive”, “transmit”, “bidirectional transmission”, “send and / or receive” can be mutually replaceable, which can be interpreted as receiving from other subjects, acquiring from protocols, acquiring from higher layers, obtaining by self-processing, autonomously implementing, and the like. The protocols include at least one of 3GPP protocols, Wi-Fi protocols, audio and / or video protocols, and the like.

[0471] In some embodiments, the term “send” can be mutually replaceable with the terms “transmit”, “report”, “transmit”, and the like.

[0472] The wireless sensing method related to the embodiments of the present disclosure can include at least one of S4101-S4103. For example, any one of S4101-S4103 can be implemented as an independent embodiment. For example, the second node receives the second sensing task request but refuses to perform the sensing task, and S4102 and S4103 are not executed. For another example, the second node receives the second sensing task request to start the execution of the sensing task, directly returns the second sensing data and / or the second sensing result to the first node, and can skip the sending of the second sensing task response, that is, S4102 is an optional step.

[0473] As shown in FIG. 5, the embodiments of the present disclosure provide a wireless sensing method, which is executed by a first terminal, and the method can include:

[0474] S5101: sending a first sensing task request.

[0475] In some embodiments, the first terminal sends the first sensing task request to the first node.

[0476] In some embodiments, the first terminal, the first node, and the related description of the first sensing task request can refer to the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0477] S5102: receiving a first sensing task response.

[0478] In some embodiments, the first sensing task response sent by the first node is received.

[0479] In some embodiments, the related description of the first perception task response can refer to the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0480] It is worth noting that in some embodiments, receiving the first perception task response is an optional operation. For example, after the first node receives the first perception task request of the first terminal, the execution of the perception task is started. After completing the execution of the perception task, the first perception data or the first perception result is sent to the first terminal, and the sending of the first perception task response is omitted during this period, thereby saving the signaling overhead.

[0481] S5103: sending the location information.

[0482] In some embodiments, the first terminal sends the location information to the first node.

[0483] In some embodiments, the first terminal sends the location information to the first node during the execution of the perception task.

[0484] In some embodiments, the first terminal sends the location information to the first node during the execution of the perception task, which is used by the first node to update the task parameters of the perception task. For example, the perception area is updated according to the location information of the first terminal, and / or the signal strength of the perception signal is updated according to the location information of the first terminal, etc.

[0485] In some embodiments, the first terminal can send the location information of the first terminal to the first node according to the second configuration contained in the first perception task response. For example, the first terminal reports its own location information on the resource indicated by the resource configuration according to the resource location in the second configuration. For another example, the first terminal sends the location information of the first terminal to the first node when detecting a trigger event corresponding to the packet sending configuration or when the current time reaches the period specified by the reporting configuration. The location information of the first terminal can be the location information determined by the first terminal based on satellite positioning, or the location information determined by the first terminal based on inertial sensors.

[0486] S5104: receiving the first perception data or the first perception result.

[0487] In some embodiments, the first terminal receives the first perception data or the first perception result sent by the first node.

[0488] In some embodiments, if the first terminal receives the first perception data from the first node, the third perception result is generated according to the first perception data.

[0489] In some embodiments, the term "information" can be mutually replaced with the terms "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", and the like.

[0490] In some embodiments, "acquire", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be mutually replaced, which can be interpreted as receiving from other subjects, acquiring from protocols, acquiring from higher layers, obtaining by self-processing, autonomously implementing, and the like. The protocols include at least one of 3GPP protocols, Wi-Fi protocols, audio and / or video protocols.

[0491] In some embodiments, the term "send" can be mutually replaced with the terms "transmit", "report", "transmit", and the like.

[0492] The wireless sensing method related to the embodiments of the present disclosure can include at least one of S5101-S5104. For example, any one of S5101-S5104 can be implemented as an independent embodiment. For example, after the first terminal sends the first sensing task request to the first node, the first node can not respond to the first terminal, and at this time S5101 will be an independent embodiment. Exemplarily, S5102 is an optional step, for example, after the first node receives the first sensing task request, the first node directly starts the execution of the sensing task without specifically returning the first sensing task response to the first terminal. For example, the duration of the sensing task is very short, and there will be sensing data or sensing results immediately. At this time, the first sensing task response is not sent, unnecessary signaling overhead is reduced, and the sensing data or sensing result is directly sent to the first terminal.

[0493] In some embodiments, S5103 is an optional step, for example, the first terminal can be a stationary first terminal or a quasi-stationary first terminal, at this time the position of the first terminal will not change much, so there is no need to send the position information of the first terminal to the first node. For another example, the first terminal requests a short-time sensing task, even if the first terminal is moving, the position of the first terminal will not change much during the execution of the sensing task, so the first terminal does not need to send the position information to the first node. In some other cases, the first terminal does not receive the first sensing task response or the first sensing task response does not contain the second configuration, in this case, the first terminal also does not need to send the position information to the first node.

[0494] In some embodiments, S5104 is an optional step. For example, if the first sensing task request of the first terminal is rejected, the first terminal also cannot receive the first sensing data and / or the first sensing result sent by the first node, and thus S5104 is also an optional step.

[0495] As shown in FIG. 6, the embodiments of the present disclosure provide a wireless sensing method, which is performed by a third node. The method can include:

[0496] S6101: receiving third information.

[0497] In some embodiments, the third node receives the third information sent by the first node.

[0498] In some embodiments, the third information is used for charging of the sensing task by the third node.

[0499] In some embodiments, the third node can be a core network node. For example, the third node can be an SF-C.

[0500] In some embodiments, the third node and the related description of the third information can refer to the corresponding embodiments of FIG. 2A.

[0501] S6102: sending fourth information.

[0502] In some embodiments, the third node sends the fourth information to the first node.

[0503] In some embodiments, the related description of the fourth information can refer to the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0504] In some embodiments, the third node sending the fourth information is an optional step. For example, the first node and the third node both belong to the nodes on the network side, and the communication security and reliability are high. In order to save signaling overhead, it can be defaulted that the third node will receive the third information, and the third node does not need to return the fourth information to the first node.

[0505] As shown in FIG. 7A, the embodiments of the present disclosure provide a sensing method, which is performed by a second terminal. The method can include:

[0506] S7101: receiving a third sensing task request.

[0507] In some embodiments, the second terminal receives the third sensing task request sent by the first node.

[0508] In some embodiments, the second terminal receives an RRC message, a MAC message, or downlink control information (DCI) information carrying the third sensing task request.

[0509] In some embodiments, the first node can be a serving node of the second terminal.

[0510] In some embodiments, the related description of the third perception task request can refer to the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0511] S7102: Perform the perception task.

[0512] In some embodiments, the second terminal transmits a perception signal according to the third perception task request and / or receives a feedback signal formed based on the perception signal.

[0513] In some embodiments, the second terminal can also obtain fourth perception data according to the transmission parameter of the perception signal and / or the reception parameter of the feedback signal. In still other embodiments, the second terminal will also generate a fourth perception result according to the fourth perception data.

[0514] As shown in FIG. 7B, it is an example of a vehicle-mounted first terminal. The vehicle-mounted first terminal is moving from cell 1 of gNB1 to cell 2 of gNB2. During the movement, the environment around the vehicle can be wirelessly perceived by gNB1 and gNB2.

[0515] For the case where the vehicle has no self-perception and self-reception capability, it can only request a perception service (or a perception service). For example, it relies on the base station or other first terminal or roadside unit to perform perception to obtain perception data or perception results. In order to reduce the service establishment and perception result application delay, the vehicle can directly request the base station to perform the self-perception and self-reception mode of the base station, the A-to-B reception mode of the base station, and the A-to-B reception mode of the first terminal, etc.

[0516] The scheme here takes the vehicle as an example to explain the initiation and response of the ISAC task request of the first terminal. During the movement of the vehicle, the serving base station and the base station participating in the perception task can be the same or different. The following provides the processing of the perception task in several different scenarios.

[0517] As shown in FIG. 2B, the wireless perception method provided by the embodiments of the present disclosure can include:

[0518] Step 1: The vehicle generates an ISAC perception request.

[0519] Step 2: The first terminal sends the ISAC perception request to the base station. For example, the first terminal sends the ISAC perception task request to the base station through RRC dedicated signaling to the serving base station, and the perception task request includes one or more of the following information: the mode of the perception task, the Qos requirement such as the delay, the perception accuracy, the feedback period of the perception result or the perception data, etc.; and the location information of the first terminal at this moment.

[0520] Step 3: The base station performs the sensing probe. Exemplarily, after receiving the request, the base station can reject the request or accept the request. If the base station accepts the request, the base station creates a sensing task and sends a response message to the first terminal to confirm the request. At this time, the response message includes one or more of the following information:

[0521] Task ID of the sensing task; the task ID is used to uniquely identify a sensing task at the base station or in the network. Exemplarily, the task ID can be: base station ID + serial number (SN) of the sensing task or PLMN + base station ID + SN of the sensing task.

[0522] Mode of the sensing task: the base station A sends the sensing signal and receives the feedback signal formed based on the sensing signal, or the base station A sends the sensing signal and the base station B receives the feedback signal formed based on the sensing signal, or the base station sends the sensing signal and the terminal receives the feedback signal, etc. Of course, the mode of the sensing task is only exemplified here, and the specific implementation is not limited to the example.

[0523] SPS configuration, which is used to periodically send the sensing data or the sensing result; here, the sensing data refers to the measured data, and the sensing result refers to the result after processing the sensing data.

[0524] CG configuration, which is used to periodically report the resource of the first terminal position information, the period of the position report, the trigger event of the position report, such as the distance change greater than a certain threshold relative to the last position report, etc.

[0525] The base station creates a sensing task of sending the sensing signal by itself and receiving the feedback signal by itself, and sends the sensing signal on the air interface and receives the returned feedback signal to obtain the sensing data.

[0526] Step 4: The base station processes the sensing data. Exemplarily, after obtaining the sensing data, the base station can process the sensing data to obtain the sensing result.

[0527] Step 5: The base station feeds back the sensing result to the first terminal.

[0528] The base station can also send the sensing data to the first terminal after obtaining the sensing data, and the first terminal is responsible for processing the sensing data to obtain the sensing result.

[0529] Step 6: The base station sends the charging assistance information to the SF-C.

[0530] Step 7: SF-C sends charging confirmation to the base station. Illustratively, after the sensing task is completed, the base station provides assistance information to the CN to assist charging, for example, charging can be based on the duration of the sensing task (that is, not dependent on traffic), the base station can forward the identification information of the first terminal and the sensing task duration and other information to the CN. For the service continuity scenario and the scenario of joint sensing of multiple base stations, the base station node responsible for processing sensing data processing is responsible for forwarding the charging assistance parameters to the CN.

[0531] As shown in FIG. 2C, the wireless sensing method provided by the embodiments of the present disclosure can include:

[0532] Step 1: The vehicle generates an ISAC sensing request.

[0533] Step 2: The first terminal sends an ISAC sensing request to the base station. Illustratively, at this time, the first terminal (for example, the first terminal can be a car) is located within the coverage range of the A base station, and initiates an ISAC sensing task.

[0534] The first terminal sends an ISAC sensing task request to the base station through RRC dedicated signaling, and the sensing task request includes one or more of the following information:

[0535] The mode of the sensing task; the sensing mode can be any one of the aforementioned sensing mode 1 to sensing mode 6; illustratively, the A base station self-initiated and self-received sensing mode, that is, the A base station sends a sensing signal and the A base station receives a feedback signal formed based on the sensing signal sent by itself. Illustratively, the sensing mode in which the A base station sends a sensing signal and the B base station receives a feedback signal. Illustratively, the A base station sends a sensing signal, and the first terminal or the second terminal receives a feedback signal. Illustratively, the first terminal or the second terminal sends a sensing signal, and the A base station receives a feedback signal.

[0536] Qos requirements, such as latency, sensing accuracy, feedback period of sensing results or sensing data, etc.

[0537] The current location information of the first terminal;

[0538] After receiving the request, the A base station can reject the request or accept the request. When accepting the request, a sensing task is created. A response message is sent to the first terminal to confirm the request, and the response message includes one or more of the following information:

[0539] The task ID of the sensing task; used to uniquely identify a sensing task under the base station or within the network, the task ID can be: base station ID + sensing task SN or PLMN + base station ID + sensing task SN;

[0540] The mode of the sensing task: the base station sends the sensing signal and receives the feedback signal, the base station A sends the sensing signal and the base station B receives the feedback signal, or the base station sends the sensing signal and the first terminal receives the feedback signal, etc.

[0541] SPS configuration, which is used for periodically sending the sensing data or the sensing result; here the sensing data refers to the measured data, and the sensing result refers to the result after processing the sensing data;

[0542] CG configuration, which is used for the resource for periodically reporting the position information of the first terminal, the period of the position reporting, the triggering event of the position reporting, such as triggering the position reporting when the distance change is greater than a certain threshold relative to the last position reporting, etc.

[0543] Step 3: The base station A sends the sensing request and / or the sensing configuration to the base station B.

[0544] Step 4: The base station B performs the sensing detection;

[0545] Step 5: The base station B sends the sensing data and / or the sensing result to the base station A. The base station A requests the base station B to initiate the sensing based on the self-sending and self-receiving mode of the base station, such as the car requesting to initiate, at this time the car is in the coverage of the base station A, and the front area is in the coverage of the base station B. The self-sending and self-receiving mode is that a device sends the sensing signal by itself and receives the feedback signal based on the sensing signal.

[0546] If the position information reported by the first terminal or the RSRP measurement result of the current serving cell is lower than a certain threshold, it indicates that the first terminal has been at the edge of the cell, or the position where the first terminal is located makes the current serving base station unable to meet the needs of the first terminal in the sensing area, i.e. the signal range of the current serving base station is limited, the current serving base station initiates the sensing task request to the neighboring base station B, and the content contained in the request information is the same as that contained in the request information sent by the first terminal to the base station A.

[0547] The base station B can refuse the request or accept the request. When accepting the request, a confirmation is replied. The base station B creates the self-sending and self-receiving sensing task mode, and sends the sensing signal on the air interface and receives the returned signal to obtain the sensing data.

[0548] Step 6: The base station A performs the sensing data processing.

[0549] After the base station obtains the sensing data, the sensing data is fed back to the serving base station (the base station A). The sensing data can be processed by the serving base station (the base station A) to obtain the sensing result.

[0550] In some other embodiments, after the base station A obtains the sensing data, the sensing data is sent to the first terminal, and the first terminal is responsible for processing the sensing data to obtain the sensing result.

[0551] Step 7: The base station A sends the sensing data and / or sensing result to the first terminal.

[0552] Step 8: The base station A sends the charging assistance information to the SF-C. Exemplarily, after the sensing task is completed, the base station provides the assistance information to the CN to assist charging. For example, the charging can be based on the duration of the sensing task (that is, not dependent on the traffic). The base station can forward the identification information of the first terminal, the duration of the sensing task, and the like to the CN. For the service continuity scenario and the scenario of joint sensing of multiple base stations, the base station node responsible for processing the sensing data is responsible for forwarding the charging assistance parameters to the CN.

[0553] Step 9: The SF-C returns the charging confirmation to the base station A.

[0554] As shown in FIG. 2D, the wireless sensing method provided by the embodiments of the present disclosure can include the following steps:

[0555] Step 1: The vehicle generates an ISAC sensing request.

[0556] Step 2: The first terminal sends the ISAC sensing request to the base station. Exemplarily, the base station A requests the base station B to initiate the sensing based on the base station self-initiated and self-received mode. The base station A and the base station B jointly sense, for example, the automobile requests to initiate. At this time, the automobile is in the coverage of the base station A, and the front area is in the coverage of the base station B.

[0557] At this time, the first terminal (automobile) is located in the coverage of the base station A, and initiates the ISAC sensing task:

[0558] Through the RRC dedicated signaling, the first terminal sends the ISAC sensing task request to the base station. The sensing task request includes the following information: the mode of the sensing task, the Qos requirement, for example, the delay, the sensing accuracy, the feedback period of the sensing result or the sensing data, and the like.

[0559] The current position information of the first terminal. After receiving the request, the base station can reject the request or accept the request and create the sensing task. A response message is sent to the first terminal to confirm the request. The response message includes one or more of the following information:

[0560] The task ID of the sensing task: used to uniquely identify a sensing task in the base station or in the network. The sensing task identification can be: base station ID + sensing task SN or PLMN + base station ID + sensing task SN.

[0561] The mode of the sensing task: the base station sends the sensing signal and receives the feedback signal, the base station A sends the sensing signal and the base station B receives the feedback signal, or the base station sends the sensing signal and the first terminal receives the feedback signal, and the like.

[0562] SPS configuration, which can be used for periodic transmission of sensing data or sensing results; here the sensing data refers to measured data, and the sensing results refer to results after processing of the sensing data;

[0563] CG configuration, which can be used for periodic reporting of resources of the first terminal position information, a position reporting period, a trigger event of position reporting, such as a distance change greater than a certain threshold relative to the last position reporting, triggering position reporting, and the like.

[0564] If the position information reported by the first terminal or the RSRP measurement result of the current serving cell is lower than a certain threshold, it indicates that the first terminal has reached the edge of the cell, or the position of the first terminal makes the current serving base station unable to meet the needs of the first terminal in the sensing area, i.e., the signal range of the current serving base station is limited, and the current serving base station initiates a sensing task request to the B base station, and the request information contains the same content and steps (1); there is also an ID of the sensing task and a sensing task mode. A base station and B base station perform joint sensing.

[0565] Step 3: A base station performs sensing detection.

[0566] Step 4: A base station performs sensing data processing.

[0567] Step 5: A base station sends a sensing response to the first terminal, which can include the current sensing result.

[0568] Step 6: A base station sends a sensing request or configuration to B base station.

[0569] Step 7: B base station performs sensing detection;

[0570] Step 8: B base station sends a sensing response or sensing result to A base station.

[0571] Step 9: A base station sends a current sensing response to the first terminal, for example, the sensing response can include the sensing result.

[0572] In some embodiments, the B base station can refuse the request, or can receive the request and reply to confirm. The response contains the same information and steps (2);

[0573] B base station creates a self-initiated and self-received sensing task mode, and sends a sensing signal on the air interface, receives the returned signal, and measures to obtain sensing data.

[0574] After the base station obtains the sensing data, the base station feeds back the sensing data to the serving base station (A base station). The serving base station (A base station) can process the sensing data to obtain the sensing result; and the sensing task SN is also included.

[0575] The A base station can also send the sensing data to the first terminal, which is responsible for processing the sensing data and obtaining the sensing result. The A base station also includes a sensing task SN.

[0576] Step 10: The A base station sends charging assistance information to the SF-C.

[0577] Step 11: The SF-C sends charging confirmation to the A base station.

[0578] After the sensing task is completed, the A base station provides assistance information to the CN to assist charging. For example, the charging can be based on the duration of the sensing task (i.e., not dependent on traffic). The A base station can forward the identification information of the first terminal, the duration of the sensing task, and other information to the CN. For the scenario of service continuity and the scenario of joint sensing of multiple base stations, the base station node responsible for processing the sensing data is responsible for forwarding the charging assistance parameters to the CN.

[0579] In some embodiments, the base station that maintains a connection with the first terminal is referred to as an anchor base station of the sensing task, and / or the anchor base station is also responsible for charging processing, sensing data processing, and / or sensing result feedback, etc.

[0580] Step 12: The first terminal obtains a sensing service response.

[0581] As shown in FIG. 2E, a sensing method can include:

[0582] The A base station requests the B base station to initiate sensing based on the A base station sending and the B base station receiving mode, for example, a vehicle requests to initiate a sensing task.

[0583] At this time, the terminal (vehicle) is located in the coverage of the A base station, initiates an ISAC sensing task, and the A base station configures the B base station as a receiving node of the sensing task and itself as a sending node, or the A base station configures the B base station as a sending node of the sensing task and itself as a receiving node.

[0584] At this time, the terminal (vehicle) is located in the coverage of the A base station, initiates an ISAC sensing task:

[0585] Through RRC dedicated signaling, the terminal sends an ISAC sensing task request to the base station, and the sensing task request includes the following information:

[0586] The mode of the sensing task (for example, base station self-sending and self-receiving, base station A sending and base station B receiving, base station sending and UE receiving, UE sending and base station receiving, UE self-sending and self-receiving, etc.), Qos requirements, such as latency, sensing accuracy, feedback period of sensing result or sensing data, etc.

[0587] The current location information of the terminal;

[0588] After the base station receives the request, it can reject the request or accept the request and create a sensing task. A response message is sent to the terminal to confirm the request, and the response message includes the following information:

[0589] An identifier of the sensing task, which is used to uniquely identify a sensing task at the base station or within the network. The sensing task identifier can be a base station ID + sensing task ID or a PLMN + base station ID + sensing task ID.

[0590] A mode of the sensing task: base station self-initiated and self-received, base station A initiated and base station B received, base station initiated and UE received, UE initiated and base station received, UE self-initiated and self-received, etc.

[0591] SPS configuration for periodic transmission of sensing data or sensing results; here, the sensing data refers to measured data, and the sensing result refers to the result after processing the sensing data.

[0592] CG configuration for periodic reporting of terminal location information, including resources for periodic reporting of location information, a period for reporting location information, and a trigger event for reporting location information, such as a change in distance greater than a certain threshold relative to the last location reporting.

[0593] A base station initiates a sensing task request to a B base station. The A base station can determine the role of the B base station in the sensing task, such as whether the B base station is the transmitter or the receiver in the base station A initiated and base station B received mode.

[0594] If the B base station is the receiver in the base station A initiated and base station B received mode, the B base station receives the measurement signal according to the configuration information. The B base station sends the sensing data measured by the B base station to the A base station.

[0595] If the B base station is the transmitter in the base station A initiated and base station B received mode, the B base station sends the signal according to the configuration information, or the B base station determines the measurement configuration information of the signal to be sent and notifies the A base station of the measurement configuration of the signal. Then, the A base station receives the measurement signal according to the measurement configuration information.

[0596] After the A base station obtains the sensing data, the A base station can process the sensing data to obtain the sensing result. The A base station sends the sensing result to the terminal.

[0597] The A base station can also send the sensing data to the terminal after obtaining the sensing data. The terminal is responsible for processing the sensing data to obtain the sensing result.

[0598] After the sensing task is finished, the base station provides assistance information to the CN to assist charging. For example, the charging can be based on the duration of the sensing task (that is, not dependent on traffic). The base station can forward the identification information of the terminal, the duration of the sensing task, and the like to the CN. For the service continuity scenario and the scenario in which multiple base stations jointly perform sensing, the base station node responsible for processing the sensing data forwards the charging assistance parameters to the CN.

[0605] Step 5: The B base station performs sensing detection and sends compressed sensing data to the A base station;

[0606] Step 6: The A base station performs sensing data processing;

[0607] Step 7: The B base station or the A base station sends sensing data or sensing results to the UE.

[0608] Step 8: The A base station sends charging assistance information to the SF-C.

[0609] Step 9: The SF-C sends charging information to the A base station.

[0610] A wireless sensing method is provided below. In the method, as shown in FIG. 2F, the base station instructs other terminals to perform a sensing task in a sensing mode in which the base station sends a sensing signal and the other terminals receive a feedback signal. Alternatively, as shown in FIG. 2G, the base station instructs other terminals to perform a sensing task in a sensing mode in which the terminal sends a sensing signal and the base station receives a feedback signal.

[0611] The terminal (automobile) is located in the coverage of the A base station and initiates an ISAC sensing task:

[0624] The A base station can also send the sensing data to the terminal after obtaining the sensing data, and the terminal processes the sensing data to obtain a sensing result.

[0625] After the sensing task is finished, the base station provides assistance information to the CN to assist charging. For example, the charging can be based on the duration of the sensing task (i.e., not dependent on traffic). The base station can forward the identification information of the terminal, the duration of the sensing task, and the like to the CN. For the service continuity scenario and the scenario in which multiple base stations jointly perform sensing, the base station node responsible for processing the sensing data processes forwards the charging assistance parameters to the CN.
