Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] Figure 1 is a schematic diagram of an application scenario of an embodiment of this application.

[0035] As shown in Figure 1, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0036] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto. That is to say, the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), 6G communication system, or future communication systems, etc.

[0037] In the communication system 100 shown in Figure 1, network device 120 may be an access network device that communicates with terminal device 110.

[0039] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0043] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. It should also be understood that "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a related relationship.

[0047] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0048] 1. Integrated communication and sensing technology

[0049] Wireless communication and sensing are two major applications of modern radio frequency (RF) technology. Sensing utilizes radio waves to detect parameters of the physical environment to achieve environmental perception such as target localization, action recognition, and imaging. Traditionally, sensing and wireless communication exist independently, and this separate design leads to a waste of wireless spectrum and hardware resources. With the advent of B5G and 6G, communication spectrum is moving towards millimeter waves, terahertz, and visible light communication; in the future, the spectrum of wireless communication will overlap with the spectrum of traditional sensing. Integrated communication and sensing technology merges these two functions. It can utilize the wireless resources of wireless communication to achieve sensing capabilities; it can leverage widely deployed cellular networks to achieve sensing services over larger areas; it can utilize base stations and multiple terminals for joint sensing to achieve higher sensing accuracy; and it can reuse wireless communication hardware modules to achieve sensing functions, reducing costs. In short, integrated communication and sensing technology enables future wireless communication systems to possess sensing capabilities, providing a foundation for the development of future smart transportation, smart cities, smart factories, drones, and other related businesses.

[0050] 2. Scenarios involving multiple sensing nodes

[0051] The nodes that transmit and receive sensing signals can be collectively referred to as sensing nodes. In wireless communication systems, the number of terminal devices (such as mobile phones, Internet of Things (IoT) devices, etc.) is large. When multiple sensing nodes (such as base stations, mobile phones, IoT devices, etc. that can transmit and / or receive sensing signals) exist around a sensed object, the joint participation of multiple sensing nodes can improve the accuracy of sensing and meet more complex sensing service requirements, providing richer sensing services. When multiple sensing nodes exist in the system, there may be a sensing control node to control and manage the entire sensing service to improve efficiency. This sensing control node can be a base station, a terminal, or a core network element. An example of multiple sensing nodes participating in sensing is shown in Figure 2.

[0052] The above provides a brief explanation of the relevant technologies / terms involved in this application, which will not be repeated in the following embodiments.

[0053] Wireless communication and sensing are two major applications of modern radio frequency technology. In sensing scenarios, environmental perception, such as target localization, action recognition, and imaging, can be achieved by using radio waves to detect parameters of the physical environment. However, the specific signaling procedures for executing sensing services are currently unclear.

[0054] In view of this, this application provides a method, apparatus, device, chip, and storage medium for executing sensing services. In this method, a first node can receive first information sent by a second node, the first information being used to request the execution of a sensing service. This method clarifies the relevant signaling flow for executing the sensing service.

[0055] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0056] Figure 3 is a flowchart illustrating the perception service execution method provided in an embodiment of this application. As shown in Figure 3, the method may include the following steps:

[0057] S301, the first node receives the first information sent by the second node, the first information is used to request the execution of the sensing service.

[0058] In this embodiment, the second node can send first information to the first node. Correspondingly, the first node can receive the first information sent by the second node. The first information can be used to request the execution of a sensing service.

[0059] In some scenarios, the phrase "request to execute sensing services" mentioned in the embodiments of this application can also be understood as "request sensing services" or "request to initiate / establish sensing services".

[0060] In some embodiments, the first node may be a node with sensing and management functions. The first node can be any entity. For example, the first node may be a base station, terminal equipment, core network element, or dedicated equipment.

[0061] In some embodiments, the second node (or a unit within the second node) can serve as an interface with a third-party application (APP) or application layer. In other words, the second node (or a unit within the second node) can send and receive information with the third-party application or application layer. In some embodiments, the second node can be a network-side node (such as a base station / core network). For example, the second node can be an AMF (Application-Based Function).

[0062] According to the method of this embodiment, the second node can request the execution of sensing services by sending first information to the first node, thereby clarifying the signaling process of how to request the execution of sensing services.

[0063] In some embodiments, the first information may be used to indicate one or more of the following 11) to 14):

[0064] 11) The third node that sends sensing signals for sensing services.

[0065] In one implementation, the first information may indicate a third node that sends a sensing signal for the sensing service, thereby allowing the first node to determine, based on the first information, that the node sending the sensing signal for the sensing service is the third node. As an example, the first information may include an identifier (ID) of the third node, which can then be used to indicate the third node.

[0066] In some embodiments, the third node may be a base station, terminal equipment, core network element, or dedicated equipment.

[0067] 12) The fourth node for receiving sensing signals for sensing services.

[0068] In one implementation, the first information may indicate a fourth node that receives sensing signals for the sensing service, thereby allowing the first node to determine, based on the first information, that the node receiving sensing signals for the sensing service is the fourth node. As an example, the first information may include an identifier for the fourth node, which can then be used to indicate the fourth node.

[0069] In some embodiments, the fourth node may be a base station, a terminal device, a core network element, or a dedicated device.

[0070] It should be noted that the third node and the fourth node in the embodiments of this application can be the same node or different nodes. When the third node and the fourth node are the same node, a mode in which the same node transmits and receives sensing signals can be supported; when the third node and the fourth node are different nodes, a mode in which node A (such as the third node) transmits sensing signals and node B (such as the fourth node) receives sensing signals can be supported.

[0071] 13) Perceive the type of business.

[0072] In one implementation, the first information may indicate the type of sensing service (such as speed measurement service, distance measurement service, angle measurement service, etc.), so that the first node can know the type of sensing service requested by the second node based on the first information.

[0073] 14) The types of perception results required for perception business.

[0074] In one implementation, the first information may indicate the type of sensing result required by the sensing service (such as channel information, received power, received signal-to-noise ratio, speed, distance, angle, delay, Doppler frequency, received signal (sensing signal) delay power spectrum, received signal (sensing signal) Doppler domain spectrum, etc.), so that the first node can know the type of sensing result required by the sensing service requested by the second node based on the first information.

[0075] In some embodiments, the method may further include: the first node sending second information to a third node and / or a fourth node. Accordingly, the third node and / or the fourth node may receive the second information sent by the first node. The second information may be used to configure sensing signals.

[0076] For example, after receiving the first information from the second node, the first node may send the second information to the third node and / or the fourth node.

[0077] In some embodiments, the second information can be carried via broadcast signaling. That is, the first node can send the second information to the third and / or fourth nodes via broadcast.

[0078] In some embodiments, the second information may be carried via dedicated signaling.

[0079] In some embodiments, the second information may be used to configure one or more of the following: time-domain resources for transmitting sensing signals; frequency-domain resources for transmitting sensing signals; antennas for transmitting sensing signals; and sensing signal sequence generation parameters.

[0080] In the embodiments of this application, the time-domain resources for transmitting sensing signals, the frequency-domain resources for transmitting sensing signals, and the antennas for transmitting sensing signals can all be collectively referred to as the transmission resources of sensing signals. That is to say, the transmission resources of sensing signals mentioned in the embodiments of this application can refer to one or more of the time-domain resources for transmitting sensing signals, the frequency-domain resources for transmitting sensing signals, and the antennas for transmitting sensing signals.

[0081] In the embodiments of this application, the sensing signal sequence can also be understood as the sequence used to transmit the sensing signal; the sensing signal sequence generation parameters can also be understood as parameters used to generate or determine the sensing signal sequence, or as parameters used to generate or determine the sensing signal.

[0082] In some embodiments, the sensing signal sequence generation parameters may include a random sequence initialization factor, or the sensing signal sequence generation parameters may be used to indicate a method for determining the random sequence initialization factor.

[0083] In some embodiments, the sensing signal sequence generation parameters can be used to indicate the type of sensing signal. As an example, the type of sensing signal can be a Sounding Reference Signal (SRS), a Channel State Information Reference Signal (CSI-RS), a Positioning Reference Signal (PRS), or a Phase Tracking Reference Signal (PTRS), etc.

[0084] According to the method of this embodiment, the first node can configure the sensing signal by sending the second information (such as configuring the transmission resources of the sensing signal and / or the parameters for generating the sensing signal sequence), thereby the third node can send the sensing signal based on the second information, and / or the fourth node can receive and measure the sensing signal based on the second information.

[0085] In some embodiments, the method may further include: a third node and / or a fourth node sending third information to a first node. Accordingly, the first node may receive the third information sent by the third node and / or the fourth node. The third information is confirmation information regarding the second information.

[0086] For example, if the first node sends a second message to the third node, and the third node confirms that it has successfully received the second message, it can send an acknowledgment message (i.e., the third message) back to the first node. Similarly, if the first node sends a second message to the fourth node, and the fourth node confirms that it has successfully received the second message, it can send an acknowledgment message (i.e., the third message) back to the first node.

[0087] In some embodiments, the third information may be a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK), or the third information may be an acknowledgment carried by Radio Resource Control (RRC) signaling.

[0088] In some embodiments, the method may further include: the first node sending fourth information to the third node and / or the fourth node. Accordingly, the third node and / or the fourth node may receive the fourth information sent by the first node. The fourth information may be used to request sensing results for a sensing service, and / or to request the execution of sensing signal measurements for the sensing service.

[0089] In this way, after receiving the fourth information, the third node can send a sensing signal in response to the fourth information; and / or, after receiving the fourth information, the fourth node can receive and measure the sensing signal in response to the fourth information to obtain the sensing results for the sensing service.

[0090] In some embodiments, the fourth information may be used to configure one or more of the following: time-domain resources for transmitting sensing signals; frequency-domain resources for transmitting sensing signals; antennas for transmitting sensing signals; sensing signal sequence generation parameters; and the type of sensing results required by the sensing service.

[0091] In one implementation, the transmission resources of the sensing signals configured in the fourth information can be the same as the transmission resources of the sensing signals configured in the third information. In another implementation, the transmission resources of the sensing signals configured in the fourth information can be a subset of the transmission resources of the sensing signals configured in the third information.

[0092] In some embodiments, the time-domain resources for transmitting sensing signals can be continuous, equally spaced, or transmitted all at once. That is, in the time domain, the sensing signals can be transmitted continuously, equally spaced, or transmitted all at once.

[0093] In some embodiments, the frequency domain resources for transmitting sensing signals can be continuous, equally spaced, or fixedly spaced frequency domain resources within the entire bandwidth, or they can be continuous, equally spaced, or fixedly spaced frequency domain resources within a portion of the bandwidth. That is, in the frequency domain, sensing signals can be transmitted continuously, equally spaced, or at fixed intervals within the entire bandwidth or a portion of the bandwidth.

[0094] In some scenarios, the spacing between adjacent frequency domain resource units in a fixed-interval frequency domain resource may not be equal. For example, a sensing signal can be transmitted on frequency domain resource units #1, #2, and #3, where frequency domain resource unit #1 is adjacent to frequency domain resource unit #2, and there is a spacing of X resource units between them; frequency domain resource unit #2 is adjacent to frequency domain resource unit #3, and there is a spacing of Y resource units between them. Here, X and Y may not be equal.

[0095] In some embodiments, the number of antennas transmitting sensing signals can be one or more. For example, the transmitting end (such as a third node) can use a single antenna to transmit sensing signals, or it can use multiple antennas to transmit sensing signals.

[0096] As one implementation method, when the transmitting end (such as a third node) uses multiple antennas to transmit sensing signals, the transmitting end can simultaneously transmit sensing signals on these multiple antennas. In some scenarios, when transmitting sensing signals simultaneously on multiple antennas, a precoding matrix can also be configured to form a beam for transmitting sensing signals.

[0097] As another implementation, when the transmitting end (such as the third node) uses multiple antennas to transmit sensing signals, within a certain time unit, the transmitting end can only transmit sensing signals on one antenna; within different time units, the transmitting end can transmit sensing signals on different antennas. For example, within time unit #1, the transmitting end can transmit sensing signals on antenna #1, and within time unit #2, the transmitting end can transmit sensing signals on antenna #2.

[0098] In some embodiments, the fourth information can be carried via broadcast signaling. That is, the first node can send the fourth information to the third and / or fourth nodes via broadcast.

[0099] In some embodiments, the fourth information can be carried via dedicated signaling. In this case, the first node can send the same third information to both the third and fourth nodes, or it can send different third information to both nodes. For example, the third information sent by the first node to the fourth node may indicate the type of sensing result required for the sensing service, but the third information sent to the third node does not need to indicate the type of sensing result required for the sensing service.

[0100] In some embodiments, the method may further include: the first node sending fifth information to the third node and / or the fourth node. Accordingly, the third node and / or the fourth node may receive the fifth information sent by the first node. The fifth information may be used to configure a measurement window, which can be used for measuring the sensed signal.

[0101] In some scenarios, this measurement window can also be understood as the time period used to measure the sensed signal.

[0102] In some embodiments, the fifth information can be used to configure the length of the measurement window and / or the occurrence period of the measurement window.

[0103] In some embodiments, the method may further include: a sixth message sent by a third node and / or a fourth node to a first node. Accordingly, the first node may receive the sixth message sent by the third node and / or the fourth node. The sixth message is an acknowledgment of the fifth message.

[0104] In some embodiments, the sixth information may be HARQ-ACK, or the sixth information may be acknowledgment information carried by RRC signaling.

[0105] In some embodiments, the method may further include: the first node sending seventh information to the third node and / or the fourth node. Accordingly, the third node and / or the fourth node may receive the seventh information sent by the first node. The seventh information may be used to activate or deactivate the measurement window.

[0106] According to the method of this embodiment, the first node can configure a dedicated measurement window for the measurement of the sensing signal by sending the fifth message, and can activate or deactivate the measurement window by sending the seventh message. This helps ensure that the measurement process of the sensing signal is not affected by other services.

[0107] In some embodiments, the method may further include: the third node transmitting a sensing signal based on one or more of the following: time-domain resources for transmitting the sensing signal; frequency-domain resources for transmitting the sensing signal; an antenna for transmitting the sensing signal; sensing signal sequence generation parameters; and a measurement window (i.e., the measurement window configured in the fifth information).

[0108] For example, after receiving the fourth information from the first node, the third node can respond to the fourth information by sending a sensing signal so that the node receiving the sensing signal (such as the fourth node) can obtain the sensing result for the sensing service based on the sensing signal.

[0109] In one implementation, the third node may transmit the sensing signal based on the transmission resources of the sensing signal configured in the fourth information (such as time-domain resources, frequency-domain resources, antennas, or one or more of these).

[0110] In one implementation, the third node can transmit the sensing signal based on the transmission resources (such as time-domain resources, frequency-domain resources, or antennas) configured in the third information. For example, if the fourth information does not configure the transmission resources for the sensing signal, the third node can transmit the sensing signal based on the transmission resources configured in the third information.

[0111] In one implementation, the third node can send sensing signals based on the measurement window. For example, the third node can send sensing signals to the fourth node within the measurement window. This reduces the time spent sending sensing signals outside the measurement window, thus helping to lower energy consumption.

[0112] It should be noted that in some scenarios, the third node may not need to consider the measurement window when sending sensing signals. In other words, the third node can send sensing signals outside of the measurement window.

[0113] In some embodiments, the method may further include: the fourth node receiving a sensing signal based on one or more of the following: time-domain resources for transmitting the sensing signal; frequency-domain resources for transmitting the sensing signal; an antenna for transmitting the sensing signal; sensing signal sequence generation parameters; and a measurement window (i.e., the measurement window configured in the fifth information).

[0114] For example, after receiving the fourth information from the first node, the fourth node can respond to the fourth information by receiving and measuring sensing signals to obtain sensing results for sensing services.

[0115] In one implementation, the fourth node may receive the sensing signal based on the transmission resources of the sensing signal configured in the fourth information (such as time-domain resources, frequency-domain resources, antennas, or one or more of these).

[0116] In one implementation, the fourth node can receive the sensing signal based on the transmission resources (such as time-domain resources, frequency-domain resources, or antennas) configured in the third information. For example, if the fourth information does not configure the transmission resources for the sensing signal, the fourth node can receive the sensing signal based on the transmission resources configured in the third information.

[0117] In one implementation, the fourth node can receive the sensing signal based on the measurement window. For example, the fourth node can receive and measure the sensing signal from the third node within this measurement window. This helps ensure that the measurement process of the sensing signal is not affected by other services.

[0118] In some embodiments, the method may further include: the fourth node sending a first sensing result for the sensing service to the first node. Accordingly, the first node may receive the first sensing result for the sensing service sent by the fourth node.

[0119] In some embodiments, the first sensing result is the sensing result obtained by the fourth node based on the received sensing signal. For example, the fourth node can obtain the first sensing result for the sensing service by receiving and measuring the sensing signal sent by the third node, and then send the first sensing result to the first node.

[0120] In some embodiments, the first sensing result may include measurement results obtained by the fourth node measuring the sensed signal. As an example, the measurement result may include, but is not limited to, one or more of the following: channel information, received power, and received signal-to-noise ratio. For instance, the measurement result may include one or more of the following: Channel State Information (CSI), Reference Signal Receiving Power (RSRP), and Received Signal Strength Indicator (RSSI).

[0121] In some embodiments, the first sensing result may include the result obtained by the fourth node after further processing of the above measurement results. As an example, the result obtained after further processing of the above measurement results may include, but is not limited to, one or more of the following: distance, speed, angle, time delay, Doppler frequency, received signal (sensing signal) time delay power spectrum, and received signal (sensing signal) Doppler domain spectrum.

[0122] In some embodiments, the type of the first sensing result is related to the type of sensing result required for the sensing service.

[0123] In one implementation, after receiving the fourth information from the first node, the fourth node can determine the type of sensing result required by the sensing service based on the fourth information. Therefore, the fourth node can send a first sensing result to the first node according to the type of sensing result required by the sensing service. That is, the type of the first sensing result sent by the fourth node to the first node is related to the type of sensing result required by the sensing service indicated in the fourth information.

[0124] For example, if the fourth information indicates that the type of sensing result required for the sensing service is speed, then the fourth node can obtain information about speed (such as speed value) based on the sensing signal and send this information about speed as the first sensing result to the first node.

[0125] According to the method of this embodiment, the fourth node can send a first sensing result to the first node based on the type of sensing result required by the sensing service. This avoids including unnecessary sensing results in the first sensing result, thereby improving signaling transmission efficiency. For example, for speed measurement services, the required sensing result type is speed. Therefore, the first sensing result sent by the fourth node can include sensing results related to speed (such as speed values) without including other types of sensing results, thus reducing the amount of information that needs to be sent and improving signaling transmission efficiency.

[0126] In some embodiments, the method may further include: the first node sending a second sensing result for the sensing service to the second node. Accordingly, the second node may receive the second sensing result for the sensing service sent by the first node.

[0127] For example, after receiving the first perception result from the fourth node, the first node can send the second perception result to the second node.

[0128] In some embodiments, the second perception result is related to the first perception result.

[0129] For example, the second perception result is related to the first perception result, and may include one or more of the following situations: the second perception result is the same as the first perception result; the second perception result includes the first perception result; the second perception result is determined based on the first perception result (or, the second perception result is obtained after further processing of the first perception result).

[0130] In some embodiments, the type of the second sensing result is related to the type of sensing result required for the sensing service.

[0131] In one implementation, after receiving first information from the second node, the first node can determine the type of sensing result required by the sensing service based on the first information. Therefore, the first node can send a second sensing result to the second node according to the type of sensing result required by the sensing service. That is, the type of the second sensing result sent by the first node to the second node is related to the type of sensing result required by the sensing service indicated in the first information.

[0132] According to the method of this embodiment, the first node can send the second perception result to the second node according to the type of perception result required by the perception service. In this way, unnecessary perception results can be avoided in the second perception result, which is conducive to improving the signaling transmission efficiency.

[0133] In this embodiment of the application, the second node may send first information to the first node to request the execution of a sensing service.

[0134] In one implementation, the method of this application embodiment can be applied to a scenario where the network side requests the execution of a sensing service (denoted as scenario #1). For example, the second node can be a network-side node (such as a base station / core network), so that the network-side node can request the execution of the sensing service, or in other words, the network-side node can initiate / establish the sensing service.

[0135] In one implementation, the method of this application embodiment can be applied to a scenario where a third node (or a third-party APP or application layer in the third node) requests to perform a perception service (denoted as scenario #2).

[0136] In one implementation, the method of this application embodiment can be applied to a scenario where a fourth node (or a third-party APP or application layer in the fourth node) requests to perform a perception service (denoted as scenario #3).

[0137] The implementation methods for scenarios #2 and #3 are explained below.

[0138] In some embodiments, for scenario #2, the method may include: a third node sending an eighth message to a second node. Correspondingly, the second node may receive the eighth message sent by the third node. The eighth message is used to request the execution of a sensing service.

[0139] In some embodiments, for scenario #3, the method may include: the fourth node sending an eighth message to the second node. Correspondingly, the second node may receive the eighth message sent by the fourth node. The eighth message is used to request the execution of a sensing service.

[0140] In some embodiments, the first information is sent by the second node upon receiving the eighth information. That is, the second node may receive the eighth information sent by the third or fourth node before sending the first information to the first node. Furthermore, the second node may send the first information to the first node in response to the eighth information.

[0141] According to the method of this embodiment, the third node or the fourth node can request the execution of sensing services by sending first information to the second node, thereby clarifying the signaling process of how to request the execution of sensing services.

[0142] In some embodiments, the eighth information may be used to indicate one or more of the following 21) to 24):

[0143] 21) The third node that sends sensing signals for sensing services.

[0144] In one implementation, the eighth information may indicate a third node that sends a sensing signal for the sensing service, thereby allowing the second node to determine, based on the eighth information, that the node sending the sensing signal for the sensing service is the third node. As an example, the eighth information may include an identifier (ID) of the third node, which can then be used to indicate the third node.

[0145] 22) The fourth node that receives sensing signals for sensing services.

[0146] In one implementation, the eighth information may indicate a fourth node receiving the sensing signal for the sensing service, thereby allowing the second node to determine, based on the eighth information, that the node receiving the sensing signal for the sensing service is the fourth node. As an example, the eighth information may include an identifier for the fourth node, which can then be used to indicate the fourth node.

[0147] 23) The type of perception service.

[0148] In one implementation, the eighth information can indicate the type of sensing service (such as speed measurement service, distance measurement service, angle measurement service, etc.), so that the second node can know the type of sensing service requested by the third or fourth node based on the eighth information.

[0149] 24) The types of perception results required for perception business.

[0150] In one implementation, the eighth information may indicate the type of sensing result required by the sensing service (such as channel information, received power, received signal-to-noise ratio, speed, distance, angle, delay, Doppler frequency, received signal (sensing signal) delay power spectrum, received signal (sensing signal) Doppler domain spectrum, etc.), so that the second node can know the type of sensing result required by the sensing service requested by the third or fourth node based on the eighth information.

[0151] In some embodiments, the type of sensing result required by the sensing service indicated in the eighth information may be the same as or different from the type of sensing result required by the sensing service indicated in the first information. For example, the type of sensing result required by the sensing service indicated in the eighth information may include speed, distance, etc.; the type of sensing result required by the sensing service indicated in the first information may include channel information, received power, etc.

[0152] In some embodiments, the first information is sent by the second node upon receiving the eighth information. In this case, the method may further include: the second node sending a third sensing result for the sensing service to the node that sent the eighth information.

[0153] For example, after receiving the second perception result from the first node, the second node can send the third perception result to the node that sent the eighth information.

[0154] In one example, the eighth piece of information is sent by the third node. Then, after receiving the second sensing result from the first node, the second node can send a third sensing result for the sensing service to the third node. Correspondingly, the third node can receive the third sensing result for the sensing service sent by the second node.

[0155] In another example, the eighth piece of information is sent by the fourth node. Then, after receiving the second sensing result from the first node, the second node can send a third sensing result for the sensing service to the fourth node. Correspondingly, the fourth node can receive the third sensing result for the sensing service sent by the second node.

[0156] It should be noted that in some scenarios, if the first perception result obtained by the fourth node based on the perception signal is the final perception result required by the fourth node, then the fourth node does not need to send the first perception result to the first node. In this case, the first node also does not need to send the second perception result to the second node, and therefore the second node does not need to send the third perception result to the fourth node.

[0157] In some embodiments, the third perception result is related to the first perception result and / or the second perception result.

[0158] For example, the third perception result is related to the first perception result, and may include one or more of the following situations: the third perception result is the same as the first perception result; the third perception result includes the first perception result; the third perception result is determined based on the first perception result (or, the third perception result is obtained after further processing of the first perception result).

[0159] For example, the third perception result is related to the second perception result, and may include one or more of the following situations: the third perception result is the same as the second perception result; the third perception result includes the second perception result; the third perception result is determined based on the second perception result (or, the third perception result is obtained after further processing of the second perception result).

[0160] In some embodiments, the type of the third sensing result is related to the type of sensing result required by the sensing service.

[0161] In one implementation, when the eighth information is sent by the third node, after receiving the eighth information, the second node can determine the type of sensing result required by the sensing service requested by the third node based on the eighth information. Therefore, the second node can send a third sensing result to the third node according to the type of sensing result required by the sensing service. That is, the type of the third sensing result sent by the second node to the third node is related to the type of sensing result required by the sensing service indicated in the eighth information sent by the third node.

[0162] In one implementation, when the eighth information is sent by the fourth node, after receiving the eighth information, the second node can determine the type of sensing result required for the sensing service requested by the fourth node. Therefore, the second node can send a third sensing result to the fourth node based on the type of sensing result required for the sensing service. That is, the type of the third sensing result sent by the second node to the fourth node is related to the type of sensing result required for the sensing service indicated in the eighth information sent by the fourth node.

[0163] According to the method of this embodiment, the second node can send the third perception result to the third or fourth node according to the type of perception result required by the perception service. In this way, unnecessary perception results can be avoided in the third perception result, which is conducive to improving the signaling transmission efficiency.

[0164] The above technical solutions in the embodiments of this application clarify the relevant signaling processes involved in the execution of sensing services.

[0165] The following describes in detail the perception service execution method provided in the embodiments of this application, combined with specific application scenarios.

[0166] For example, the perception service execution method provided in this application involves the following nodes and / or units: a perception service management node (corresponding to the aforementioned first node), a perception signal receiving node (corresponding to the aforementioned fourth node), a perception signal sending node (corresponding to the aforementioned third node), and a service management unit. In some scenarios, the service management unit may be a node (such as the aforementioned second node), or it may be a unit within a node (such as a unit within the aforementioned second node).

[0167] The nodes and / or units mentioned above are briefly described below.

[0168] The sensing service management node is used to initiate sensing signal configuration, initiate sensing signal measurement, collect sensing signal measurement results, and process the sensing signal measurement results into sensing results. In this embodiment, the sensing service management node may include a processing module with independent sensing-related functions. This module can independently complete the initiation of sensing services and data collection. For example, when there is a sensing requirement, this module can be activated. This module can exclusively serve the sensing service, thus remaining unaffected by other services (such as communication services) and without adversely affecting the entire system.

[0169] Sensing signal receiving node: Used to measure sensing signals according to the sensing signal configuration and feed back the measurement results to the sensing service management node. In the embodiments of this application, the sensing signal receiving node can be a communication base station, a terminal, or a dedicated device, thereby enabling flexible networking and efficient utilization of existing network equipment.

[0170] Sensing signal transmitting node: Used to transmit sensing signals according to the sensing signal configuration. In the embodiments of this application, the sensing signal transmitting node can be a communication base station, a terminal, or a dedicated device, thereby enabling flexible network configuration and efficient utilization of existing network equipment.

[0171] Service Management Unit: Serves as an interface with third-party applications (APPs) or the application layer, used to receive service awareness requests. One possible approach is to implement the service management unit's functionality by adding a service awareness interface to the existing system's AMF (Application Function Framework). This allows the system to support service awareness without affecting existing system functionality.

[0172] In some embodiments, sensing services can be initiated by a third-party app or application layer, and a sensing service request can be sent to the sensing service management node through the service management unit. The sensing service management node can control the sensing signal sending node and sensing signal receiving node to perform sensing signal measurement, and feed back the measurement results or sensing results to the service management unit, thereby enabling the service management unit to complete the service request initiated by the upper layer (third-party app or application layer).

[0173] In some embodiments, the sensing signal transmitting node and the sensing signal receiving node may be the same node or different nodes. For example, the same node refers to a node that is geographically similar and shares the same signal processing hardware module; different nodes refer to nodes that do not share the same signal processing hardware module.

[0174] In some embodiments, sensing services can be initiated by the network side (such as base stations / core networks) or by sensing nodes, thus supporting flexible and varied sensing service requirements.

[0175] For example, when a sensing signal transmitting node needs to sense the quality of the signal it transmits or the surrounding environment of the node, the sensing signal transmitting node can initiate a sensing service. In this way, the sensing signal transmitting node can determine the quality of the signal received by different sensing signal receiving nodes when it transmits the signal based on the received sensing data.

[0176] For example, when a sensing signal receiving node needs to sense the quality of signals sent by different sensing signal sending nodes, the sensing signal receiving node can initiate a sensing service.

[0177] For example, when the network needs to know the environment or the status of the target being sensed within the coverage area or a specific area, the network can initiate a sensing service to measure sensing signals and collect data within the coverage area or a specific area in order to determine the environmental quality (such as channel quality) or the parameters of the target being sensed.

[0178] As examples, the following describes two implementation schemes (referred to as Scheme 1 and Scheme 2) of the perception service execution method provided in the embodiments of this application.

[0179] Option 1

[0180] Option 1 can be applied to scenarios where the network side initiates sensing services. For example, when the network side needs to know the environmental conditions or sensing targets within its coverage area or a specific region, it can initiate sensing services to measure sensing signals and collect data within the coverage area or a specific region to determine environmental quality or sensing target parameters.

[0181] In Option 1, the sensing service can be initiated by the network side. For example, a service management unit can be deployed on the network side, which can send a first request to the sensing service management node to request the sensing service. Further, the sensing service management node can respond to the first request by initiating a sensing signal processing procedure and further processing the received sensing data before reporting it back to the service management unit, or directly reporting the received sensing data back to the service management unit.

[0182] Figure 4 illustrates a possible implementation flow diagram of Scheme 1. As shown in Figure 4, this implementation flow may include the following steps:

[0183] S401, the service management unit sends a first request (corresponding to the aforementioned first information) to the sensing service management node.

[0184] In this step, the service management unit may send a first request to the sensing service management node. This first request can be used to request a sensing service, or in other words, to request the execution / establishment / initiation of a sensing service.

[0185] In some embodiments, the first request may include one or more of the following information: the type of sensing service; information about the sensing signal transmitting node (such as the identifier of the sensing signal transmitting node); information about the sensing signal receiving node (such as the identifier of the sensing signal receiving node); and sensing data report type information.

[0186] The sensing data report type information can be used to indicate the type of sensing data (sensing results) required for sensing services, or in other words, to indicate the type of sensing data (sensing results) expected to be collected. This allows for the customization of corresponding data report types according to different service requirements, thereby improving signaling transmission efficiency. For example, for ranging services, the sensing data report type can be set to distance. Thus, when reporting sensing data, distance information can be transmitted without transmitting sensing data such as channel information and received power, thereby improving signaling transmission efficiency.

[0187] In some embodiments, the sensing signal transmitting node and the sensing signal receiving node can be the same node, that is, a mode in which the same node transmits and receives sensing signals can be supported. In some embodiments, the sensing signal transmitting node and the sensing signal receiving node can be different nodes, that is, a mode in which node A transmits sensing signals and node B receives sensing signals can be supported.

[0188] S402, Sensing signal processing flow.

[0189] Upon receiving the first request, the sensing service management node can respond to it and initiate the sensing signal processing procedure. The detailed steps of the sensing signal processing procedure will be described below with reference to Figures 7 to 9, and will not be elaborated here.

[0190] Through the sensing signal processing flow, the sensing business management node can collect sensing data (sensing results).

[0191] In some embodiments, the sensing data may include: sensing signal measurement results, and / or sensing results obtained after processing the sensing signal measurement results.

[0192] As an example, the results of sensed signal measurements may include, but are not limited to, one or more of the following: channel information, received power, and received signal-to-noise ratio. For example, sensed signal measurement results may include: CSI, RSRP, RSSI, etc.

[0193] As an example, the sensing results obtained after processing the sensing signal measurement results may include, but are not limited to, one or more of the following: distance, speed, angle, time delay, Doppler frequency, received signal (sensing signal) time delay power spectrum, and received signal (sensing signal) Doppler domain spectrum calculated by the sensing algorithm.

[0194] S403, the sensing service management node sends sensing data (corresponding to the aforementioned second sensing result) to the service management unit.

[0195] In this step, the sensing service management node can send the collected sensing data to the service management unit, or it can further process the collected sensing data before sending it to the service management unit.

[0196] Option 2

[0197] Option 2 can be applied to scenarios where sensing nodes (such as sensing signal transmitting nodes / sensing signal receiving nodes) initiate sensing services. For example, when a sensing signal transmitting node needs to sense the quality of its transmitted signal or its surrounding environment, it can initiate a sensing service. Thus, the sensing signal transmitting node can determine the quality of the signal received by different sensing signal receiving nodes based on the received sensing data. Similarly, when a sensing signal receiving node needs to sense the quality of signals transmitted by different sensing signal transmitting nodes, it can also initiate a sensing service.

[0198] In Scheme 2, the sensing service can be initiated by the sensing signal sending node or the sensing signal receiving node, and then the sensing service can be requested through the service management unit.

[0199] Figure 5 illustrates a possible implementation flow diagram of Scheme 2, in which the sensing service can be initiated by the sensing signal transmitting node. As shown in Figure 5, this implementation flow may include the following steps:

[0200] S501, the sensing signal transmitting node sends a second request (corresponding to the aforementioned eighth information) to the service management unit.

[0201] In this step, the sensing signal transmitting node can send a second request to the service management unit. This second request can be used to request sensing services, or in other words, to request the execution / establishment / initiation of sensing services. By sending the second request, the sensing signal transmitting node can inform the service management unit that it has a sensing need.

[0202] In some embodiments, the second request may include one or more of the following information: the type of sensing service; information about the sensing signal transmitting node (such as the identifier of the sensing signal transmitting node); information about the sensing signal receiving node (such as the identifier of the sensing signal receiving node); and sensing data report type information.

[0203] S502, the service management unit sends a first request (corresponding to the aforementioned first information) to the sensing service management node.

[0204] After receiving a second request from the sensing signal sending node, the service management unit can respond to the second request by sending a first request to the sensing service management node. The first request can be used to request a sensing service, or in other words, to request the execution / establishment / initiation of a sensing service.

[0205] In some embodiments, the first request may include one or more of the following information: the type of sensing service; information about the sensing signal transmitting node (such as the identifier of the sensing signal transmitting node); information about the sensing signal receiving node (such as the identifier of the sensing signal receiving node); and sensing data report type information.

[0206] It should be noted that the type of sensing data returned in the first request and the type of sensing data returned in the second request may be the same or different. For example, the type of sensing data returned in the first request may indicate that the type of sensing data (sensing results) to be collected includes speed, distance, etc.; the type of sensing data returned in the second request may indicate that the type of sensing data (sensing results) to be collected includes channel information, received power, etc.

[0207] S503, Sensing Signal Processing Flow.

[0208] Upon receiving the first request, the sensing service management node can respond to it and initiate the sensing signal processing procedure. The detailed steps of the sensing signal processing procedure will be described below with reference to Figures 7 to 9, and will not be elaborated here.

[0209] Through the sensing signal processing flow, the sensing business management node can collect sensing data (sensing results).

[0210] In some embodiments, the sensing data may include: sensing signal measurement results, and / or sensing results obtained after processing the sensing signal measurement results.

[0211] As an example, the results of sensed signal measurements may include, but are not limited to, one or more of the following: channel information, received power, and received signal-to-noise ratio. For example, sensed signal measurement results may include: CSI, RSRP, RSSI, etc.

[0212] As an example, the sensing results obtained after processing the sensing signal measurement results may include, but are not limited to, one or more of the following: distance, speed, angle, time delay, Doppler frequency, received signal (sensing signal) time delay power spectrum, and received signal (sensing signal) Doppler domain spectrum calculated by the sensing algorithm.

[0213] S504, the sensing service management node sends sensing data (corresponding to the aforementioned second sensing result) to the service management unit.

[0214] In this step, the sensing service management node can send the collected sensing data to the service management unit, or it can further process the collected sensing data before sending it to the service management unit.

[0215] S505, the service management unit sends sensing data (corresponding to the aforementioned third sensing result) to the sensing signal sending node.

[0216] In this step, the service management unit can send the sensing data from the sensing service management node to the sensing signal sending node, or it can further process the sensing data from the sensing service management node before sending it to the sensing signal sending node.

[0217] Figure 6 illustrates another possible implementation flow diagram for Scheme 2, in which the sensing service can be initiated by the sensing signal receiving node. As shown in Figure 6, this implementation flow may include the following steps:

[0218] S601, the sensing signal receiving node sends a second request (corresponding to the aforementioned eighth information) to the service management unit.

[0219] In this step, the sensing signal receiving node can send a second request to the service management unit. This second request can be used to request sensing services, or in other words, to request the execution / establishment / initiation of sensing services. By sending the second request, the sensing signal receiving node can inform the service management unit that it has a sensing need.

[0220] In some embodiments, the second request may include one or more of the following information: the type of sensing service; information about the sensing signal transmitting node (such as the identifier of the sensing signal transmitting node); information about the sensing signal receiving node (such as the identifier of the sensing signal receiving node); and sensing data report type information.

[0221] S602, the service management unit sends a first request (corresponding to the aforementioned first information) to the sensing service management node.

[0222] After receiving a second request from the sensing signal receiving node, the service management unit can respond to the second request by sending a first request to the sensing service management node. The first request can be used to request a sensing service, or in other words, to request the execution / establishment / initiation of a sensing service.

[0223] In some embodiments, the first request may include one or more of the following information: the type of sensing service; information about the sensing signal transmitting node (such as the identifier of the sensing signal transmitting node); information about the sensing signal receiving node (such as the identifier of the sensing signal receiving node); and sensing data report type information.

[0224] It should be noted that the perceived data return type information in the first request and the perceived data return type information in the second request may be the same or different.

[0225] S603, Sensing signal processing flow.

[0226] Upon receiving the first request, the sensing service management node can respond to it and initiate the sensing signal processing procedure. The detailed steps of the sensing signal processing procedure will be described below with reference to Figures 7 to 9, and will not be elaborated here.

[0227] Through the sensing signal processing flow, the sensing business management node can collect sensing data (sensing results).

[0228] In some embodiments, the sensing data may include: sensing signal measurement results, and / or sensing results obtained after processing the sensing signal measurement results.

[0229] As an example, the results of sensed signal measurements may include, but are not limited to, one or more of the following: channel information, received power, and received signal-to-noise ratio. For example, sensed signal measurement results may include: CSI, RSRP, RSSI, etc.

[0230] As an example, the sensing results obtained after processing the sensing signal measurement results may include, but are not limited to, one or more of the following: distance, speed, angle, time delay, Doppler frequency, received signal (sensing signal) time delay power spectrum, and received signal (sensing signal) Doppler domain spectrum calculated by the sensing algorithm.

[0231] S604, the perception service management node sends perception data (corresponding to the aforementioned second perception result) to the service management unit.

[0232] In this step, the sensing service management node can send the collected sensing data to the service management unit, or it can further process the collected sensing data before sending it to the service management unit.

[0233] S605, the service management unit sends sensing data (corresponding to the aforementioned third sensing result) to the sensing signal receiving node.

[0234] In this step, the service management unit can send the sensing data from the sensing service management node to the sensing signal receiving node, or it can further process the sensing data from the sensing service management node before sending it to the sensing signal receiving node.

[0235] The following section, with reference to Figures 7 to 9, details the steps of the sensing signal processing flow.

[0236] For example, the sensing signal processing flow may include one or more of the following processes: sensing signal configuration process, sensing signal transmission / measurement process, measurement window configuration / activation / deactivation process, and sensing signal reconfiguration process.

[0237] Figure 7 illustrates a typical schematic diagram of the sensing signal configuration / reconfiguration process. As shown in Figure 7, the sensing signal configuration / reconfiguration process may include the following steps:

[0238] S701, the sensing service management node sends sensing signal configuration to the sensing signal sending node.

[0239] S702, the sensing service management node sends the sensing signal configuration to the sensing signal receiving node.

[0240] It should be noted that the execution order of S701 and S702 is not restricted in the embodiments of this application. That is, the execution order of S701 and S702 can be interchanged, or S701 and S702 can be executed simultaneously.

[0241] In some embodiments, the sensing signal configuration (corresponding to the aforementioned second information) can be sent via broadcast signaling. That is, the sensing service management node can simultaneously send the sensing signal configuration to both the sensing signal sending node and the sensing signal receiving node via broadcast.

[0242] In some embodiments, the sensing signal configuration can be carried via dedicated signaling.

[0243] In some embodiments, the sensing signal configuration may include one or more of the following configurations: periodic configuration of the sensing signal, time-domain resource configuration of the sensing signal, frequency-domain resource configuration of the sensing signal, and antenna configuration of the sensing signal.

[0244] In some embodiments, in the time domain, the sensing signal may be transmitted continuously, at equal intervals, or all at once.

[0245] In some embodiments, in the frequency domain, the sensing signal can be transmitted continuously, at equal intervals, or at fixed intervals within the full bandwidth or a portion of the bandwidth.

[0246] In some embodiments, it is possible to support the transmission of sensing signals via a single antenna or multiple antennas.

[0247] As one implementation method, when transmitting sensing signals through multiple antennas, sensing signals can be transmitted simultaneously on multiple antennas.

[0248] As another implementation method, when transmitting sensing signals via multiple antennas, sensing signals can only be transmitted on one antenna within a defined time unit; however, sensing signals can be transmitted on different antennas within different time units. For example, sensing signals can be transmitted on antenna #1 within time unit #1, and on antenna #2 within time unit #2.

[0249] S703, the sensing signal transmitting node sends a confirmation message of sensing signal configuration (corresponding to the aforementioned third message) to the sensing service management section.

[0250] S704, the sensing signal receiving node sends a confirmation message of sensing signal configuration (corresponding to the aforementioned third message) to the sensing service management section.

[0251] It should be noted that the execution order of S703 and S704 is not restricted in the embodiments of this application. That is, the execution order of S703 and S704 can be interchanged, or S703 and S704 can be executed simultaneously.

[0252] It should also be noted that in some scenarios, S703 and / or S704 can be omitted (or not executed).

[0253] Figure 8 illustrates a typical schematic diagram of a sensing signal transmission / measurement process. As shown in Figure 8, the sensing signal transmission / measurement process may include the following steps:

[0254] S801, the sensing service management node sends a third request to the sensing signal sending node.

[0255] S802, the sensing service management node sends a third request to the sensing signal receiving node.

[0256] In S801 and S802, the sensing service management node can send a third request (corresponding to the aforementioned fourth information) to the sensing signal sending node and the sensing signal receiving node. This third request can be used to request sensing data and / or to request the execution of sensing signal measurements.

[0257] In some embodiments, the third request may be used to configure one or more of the following: the resource location (time domain location, frequency domain location, antenna port) of the sensed signal measurement; the sensed signal (sequence); and the sensed data report type.

[0258] In some embodiments, the third request can be sent via broadcast signaling. That is, the sensing service management node can simultaneously send the third request to both the sensing signal sending node and the sensing signal receiving node via broadcast. In this case, the third request can be received by both the sensing signal sending node and the sensing signal receiving node simultaneously.

[0259] In some embodiments, the third request can be sent via dedicated signaling. That is, the sensing service management node can send the third request to both the sensing signal sending node and the sensing signal receiving node through dedicated signaling configuration. In this case, the configuration content in the third request sent to the sensing signal sending node and the sensing signal receiving node can be the same or different. For example, the third request sent to the sensing signal sending node can configure sensing signal-related parameters (such as the resource location measured by the sensing signal, the sensing signal (sequence)), without configuring measurement result-related parameters (such as the sensing data report type).

[0260] S803, the sensing signal transmitting node sends a sensing signal to the sensing signal receiving node.

[0261] After receiving the third request, the sensing signal transmitting node can send the sensing signal according to the sensing signal related parameters configured in the third request (such as the resource location measured by the sensing signal, the sensing signal (sequence)).

[0262] In some scenarios, if the resource location for sensing signal measurement is not configured in the third request, the sensing signal sending node can send the sensing signal according to the resource configuration in the sensing signal configuration (such as the sensing signal configuration received in S701).

[0263] S804, the sensing signal receiving node performs sensing signal measurement.

[0264] In this step, the sensing signal receiving node can perform sensing signal measurement according to the sensing signal (sequence) configured in the third request to obtain the sensing signal measurement result.

[0265] As an example, the results of sensed signal measurements may include, but are not limited to, one or more of the following: channel information, received power, and received signal-to-noise ratio. For example, sensed signal measurement results may include: CSI, RSRP, RSSI, etc.

[0266] In some embodiments, the sensing signal receiving node can further process the sensing signal measurement results using a sensing algorithm to calculate sensing results such as distance, speed, angle, time delay, Doppler frequency, received signal (sensing signal) time delay power spectrum, and received signal (sensing signal) Doppler domain spectrum.

[0267] S805, the sensing signal receiving node sends sensing data (corresponding to the aforementioned first sensing result) to the sensing service management node.

[0268] In this step, the sensing signal receiving node can report the sensing data obtained in S804 (such as sensing signal measurement results, and / or sensing results obtained after processing the sensing signal measurement results) to the sensing service management node according to the sensing data report type configured in the third request.

[0269] In some scenarios, when the sensing service is initiated by the sensing signal receiving node, if the sensing data obtained in S804 is the same sensing data required by the sensing signal receiving node, then the sensing signal receiving node does not need to send the sensing data to the sensing service management node.

[0270] Figure 9 illustrates a typical measurement window configuration / activation / deactivation process. As shown in Figure 9, the measurement window configuration / activation / deactivation process may include the following steps:

[0271] S901, the sensing service management node sends the sensing signal measurement window configuration to the sensing signal sending node.

[0272] S902, the sensing service management node sends the sensing signal measurement window configuration to the sensing signal receiving node.

[0273] In S901 and S902, the sensing service management node can send sensing signal measurement window configuration (corresponding to the aforementioned fifth information) to the sensing signal sending node and sensing signal receiving node. The sensing signal measurement window configuration can be used to configure the measurement window for sensing signal measurement, for example, configuring information such as the length of the measurement window and the occurrence period of the measurement window.

[0274] It should be noted that the execution order of S901 and S902 is not restricted in the embodiments of this application. That is, the execution order of S901 and S902 can be interchanged, or S901 and S902 can be executed simultaneously.

[0275] It should also be noted that in some scenarios, it is not necessary to send the sensing signal measurement window configuration to the sensing signal sending node. That is, S901 can be omitted (or not executed).

[0276] S903, the sensing signal transmitting node sends confirmation information of the sensing signal measurement window configuration to the sensing service management node (corresponding to the sixth information mentioned above).

[0277] S904, the sensing signal receiving node sends confirmation information of the sensing signal measurement window configuration to the sensing service management node (corresponding to the aforementioned sixth information).

[0278] It should be noted that the execution order of S903 and S904 is not restricted in the embodiments of this application. That is, the execution order of S903 and S904 can be interchanged, or S903 and S904 can be executed simultaneously.

[0279] It should also be noted that in some scenarios, if S901 is not executed, then S903 can be omitted (or not executed).

[0280] It should also be noted that in some scenarios, S903 and S904 can be omitted (or not executed).

[0281] S905, the sensing service management node sends a sensing signal measurement window activation / deactivation signaling to the sensing signal sending node (corresponding to the aforementioned seventh information).

[0282] S906, the sensing service management node sends a sensing signal measurement window activation / deactivation signaling to the sensing signal receiving node (corresponding to the aforementioned seventh information).

[0283] In S905 and S906, the sensing service management node can activate or deactivate the sensing signal measurement window through dedicated activation or deactivation signaling.

[0284] It should be noted that the execution order of S905 and S906 is not restricted in the embodiments of this application. That is, the execution order of S905 and S906 can be interchanged, or S905 and S906 can be executed simultaneously.

[0285] It should also be noted that in some scenarios, if S901 is not executed, then S905 can be omitted (or not executed).

[0286] It is understandable that when sensing services are applied, there should be specific sensing service request nodes, sensing service configuration nodes, sensing signal processing nodes, etc. However, in existing systems, it is not clearly defined which network node initiates the sensing service request or which network node performs data measurement and reporting. Furthermore, there is no signaling flow applied to sensing service initiation and sensing service data requests. Therefore, this application provides a signaling flow for sensing services, including sensing service requests, sensing signal configuration, and sensing signal measurement. Moreover, a sensing service management node is defined to configure sensing signal sending nodes and sensing signal receiving nodes for transmitting sensing signals and reporting measurement results.
