The base station can also refer to a communication module, a modem or a chip for being provided in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs the base station function in D2D, V2X, machine-to-machine (M2M) communications, a network side device in a 6G network, a device that performs the base station function in a future communication system, and the like. The base station can support networks with the same or different access technologies. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network equipment.

[0035] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0036] Network system architecture

[0037] The following describes the network architecture of a communication system using a 5G communication system as an example with reference to FIG2 and FIG3 .

[0038] Figures 2 and 3 both illustrate the network architecture of a 5G communication system. In Figure 2, core network elements are connected to each other through agreed interfaces, i.e., the core network adopts a network element interface mode. In Figure 3, core network elements interact by invoking services provided by the network elements, i.e., the core network adopts a network element provision service mode. This application does not limit the use of interfaces or service invocation modes between core network elements.

[0039] As shown in Figure 2 or Figure 3, the terminal device establishes an access layer connection with the access network (AN) through the Uu port, thereby exchanging access layer messages and wireless data transmission. The terminal device establishes a non-access stratum (NAS) connection with the access and mobility management function (AMF) through the N1 port to exchange NAS messages. The AMF is the mobility management function in the core network, and the session management function (SMF) is the session management function in the core network. In addition to managing the mobility of the UE, the AMF is also responsible for forwarding session management-related messages between the terminal device and the SMF. The policy control function (PCF) is a network element in the core network responsible for formulating policies related to mobility management, session management, billing, etc. for the terminal device. The user plane function (UPF) can transmit data with the external data network (DN) through the N6 interface, and can also transmit data with the RAN through the N3 interface. After the terminal device accesses the 5G network through the Uu port, it can establish a protocol data unit (PDU) session under the control of the SMF to transmit data.

[0040] Sensing Network

[0041] In a narrow sense, a perception network can refer to a system with the capabilities of target positioning, target imaging, target detection, target tracking, and target recognition. Target positioning can include one or more of the following perception operations on the perceived target: ranging, speed measurement, and angle measurement.

[0042] In a broad sense, a perceptual network can refer to a system that has the attributes and status of any business, network, user, terminal, and environmental objects.

[0043] From the perspective of perception applications, perception can be classified into the following categories: outdoor / wide-area / local-area applications and indoor / local-area applications.

[0044] Outdoor / wide-area / local-area applications may include one or more of the following: smart cities, smart transportation / high-speed rail, and low-altitude applications. Smart cities, for example, may include weather monitoring and environmental imaging. Smart transportation / high-speed rail, for example, may include one or more of the following: high-precision map construction, road supervision, and intrusion detection. Low-altitude applications, for example, may include one or more of the following: drone monitoring, drone obstacle avoidance, flight intrusion detection, and flight path management.

[0045] Indoor / local applications may include one or more of the following: smart home, health management, and smart factory. Health management, for example, may include one or more of respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, and mobile trajectory tracking. Smart factory applications, for example, may include one or more of intrusion detection, material detection, and item defect detection.

[0046] It should be noted that the above-mentioned applications of perception and classification of perception applications are exemplary, and the application scope of perception is not limited to the above examples.

[0047] Perception and communication integration

[0048] Perception is a key application of modern RF technology. Perception can be achieved using radio electromagnetic waves. For example, perception technology can use radio waves to detect parameters of the physical environment to achieve environmental perception, such as target location, motion recognition, and imaging. Another important application of modern RF technology is wireless communication. Separate design between perception and wireless communication—a separate design—leads to a waste of wireless spectrum and hardware resources.

[0049] With technological advancements, in some networks (such as 6G or beyond 5G (B5G) networks), communication spectrum can be based on millimeter waves, terahertz, visible light, and other technologies. In other words, the wireless communication spectrum can overlap with the perception spectrum. Next-generation networks (such as 6G networks) may be a fusion of at least two of the following: mobile communication networks, perception networks, and computing power networks.

[0050] Integrated communication and perception technology can merge wireless communication and perception functions. This technology can enable a wide range of capabilities. For example, it can leverage wireless communication resources to implement perception. Alternatively, it can leverage widely deployed cellular networks to provide perception services over a wider range. Furthermore, it can leverage network equipment and multiple terminal devices for joint perception, achieving higher perception accuracy. Furthermore, it can reuse wireless communication hardware modules to implement perception functions, reducing costs.

[0051] It is understandable that integrated communication and perception technology can enable wireless communication systems to have perception capabilities, providing a foundation for the development of smart transportation, smart cities, smart factories, drones and other businesses.

[0052] To enable mobile communication networks to support sensing capabilities, sensing network elements can be deployed within the network. These elements can be located, for example, within the core network. They can be used for one or more of the following: receiving sensing requests, selecting sensing nodes, and sending sensing instructions to sensing nodes. Sensing nodes can send and / or receive sensing signals to perceive the target. Sensing nodes can include, for example, access network devices and / or terminal devices.

[0053] The applicant of this application has found that in the related art, the number of sensing tasks that sensing nodes can participate in is limited, and correspondingly, the number of sensing nodes corresponding to the sensing tasks is also limited. Among them, the sensing nodes corresponding to the sensing tasks may include: one or more of the nodes participating in the sensing tasks and the nodes performing the sensing tasks. This will lead to limited support for sensing services in the mobile communication network. For example, in the related art, only the sensing network element is supported to select the same sensing node to perform a sensing task. In other words, only the self-transmission and self-reception of the sensing node is supported. That is, the sensing node needs to send the wireless signal associated with the sensing service (referred to as the sensing signal or wireless signal for short) by itself, and receive the wireless signal by itself. It can be understood that since the sensing node can only participate in the sensing task of receiving and sending the sensing signal by itself, the sensing tasks that the system can perform have certain limitations.

[0054] Figure 4 is a schematic flow chart of a wireless communication method provided by an embodiment of the present application to solve the above problem. The method shown in Figure 4 can be executed by a first network element and a first sensing node.

[0055] The first network element may, for example, be a network element having a sensing function. For example, the first network element may be a network element having one or more of the following functions: receiving a sensing request, selecting a sensing node, and sending a sensing instruction to a sensing node. In some embodiments, the first network element may be a network element in a core network. Optionally, the first network element may also be referred to as a sensing function (SF) network element.

[0056] The first sensing node may be used to receive and / or send wireless signals. In other words, the first sensing node may be a sending node and / or a receiving node of the wireless signal.

[0057] The first sensing node may include a terminal device and / or an access network device. For example, the first sensing node may be a terminal device, and the first sensing node may transmit wireless signals. Correspondingly, the receiving node that receives the wireless signal may be another terminal device or a network device. For another example, the first sensing node may be a terminal device, and the first sensing node may receive wireless signals. Correspondingly, the sending node that sends the wireless signal may be another terminal device or a network device. For another example, the first sensing node may be a network device, and the first sensing node may transmit wireless signals. Correspondingly, the receiving node that receives the wireless signal may be another network device or a terminal device. For another example, the first sensing node may be a network device, and the first sensing node may receive wireless signals. Correspondingly, the sending node that sends the wireless signal may be another network device or a terminal device.

[0058] The method shown in FIG. 4 may include step S410 .

[0059] In step S410, the first network element sends a first instruction to the first sensing node.

[0060] The first instruction may include one or more of the following information: identification information of the perception task, identity information of the first perception node in the perception task, and identification information of other nodes participating in the perception task.

[0061] A sensing task is a task related to sensing a sensed target. The identification (ID) information of the sensing task can be used to indicate the identity of the sensing task. Based on the identification of the sensing task, the sensing task can be distinguished from other sensing tasks. It is understood that the communication system can perform one or more sensing tasks. Using the identification information of the sensing task, the first network can indicate to the first sensing node the sensing task in which the first sensing node is participating.

[0062] It should be noted that the identification of the sensing task can be allocated by the first network element. In other words, the first network element can allocate different identifications to different sensing tasks.

[0063] The sensing task can be performed by multiple sensing nodes. The multiple sensing nodes may include a transmitting node corresponding to the sensing task and a receiving node corresponding to the sensing task. The transmitting node is used to transmit wireless signals. The receiving node is used to receive wireless signals. The wireless signals received by the receiving node may be wireless signals reflected by the sensing target. It should be noted that the transmitting node and receiving node corresponding to the sensing task can be different nodes.

[0064] The plurality of sensing nodes may include the first sensing node. The identity information of the first sensing node in the sensing task is used to indicate whether the first sensing node is a sending node or a receiving node corresponding to the sensing task. The identity information can be used to determine whether the first sensing node is a sending node or a receiving node.

[0065] The present application does not limit the indication method of the identity information of the first sensing node in the sensing task. As a possible implementation method, the identity information of the first sensing node in the sensing task can be represented by the first bit. For example, the first bit being 0 can indicate that the first sensing node is the sending node corresponding to the sensing task; the first bit being 1 can indicate that the first sensing node is the receiving node corresponding to the sensing task. Alternatively, the first bit being 1 can indicate that the first sensing node is the sending node corresponding to the sensing task; the first bit being 0 can indicate that the first sensing node is the receiving node corresponding to the sensing task. As another possible implementation method, the identity information of the first sensing node in the sensing task can be represented by a first Boolean value. For example, the first Boolean value being true can indicate that the first sensing node is the sending node corresponding to the sensing task; the first Boolean value being false can indicate that the first sensing node is the receiving node corresponding to the sensing task. Alternatively, the first Boolean value being false can indicate that the first sensing node is the sending node corresponding to the sensing task; the first Boolean value being true can indicate that the first sensing node is the receiving node corresponding to the sensing task.

[0066] Other nodes of the sensing task may include: some or all of the multiple nodes that perform the sensing task, except the first sensing node. For example, if the first sensing node is the sending node corresponding to the sensing task, the other nodes may include the receiving node corresponding to the sensing task. That is, when the first sensing node is the sending node corresponding to the sensing task, the first network element may indicate the identifier of the receiving node corresponding to the sensing task to the first sensing node through a first instruction. Alternatively, if the first sensing node is the receiving node corresponding to the sensing task, the other nodes may include the sending node corresponding to the sensing task. That is, when the first sensing node is the receiving node corresponding to the sensing task, the first network element may indicate the identifier of the sending node corresponding to the sensing task to the first sensing node through a first instruction.

[0067] It can be seen that the number of nodes participating in the perception task is greater than 1. That is to say, the same perception task can be performed by different perception nodes. The network device can coordinate multiple nodes participating in the perception task through the first instruction. For example, based on the first instruction, multiple nodes can determine one or more of the following information: information about the perception task that needs to be collaboratively performed, their respective identity information (for example, whether it is a sending node or a receiving node), and information about other nodes participating in the perception task. Therefore, based on the first instruction, multiple perception nodes can collaboratively perform the same perception task, thereby realizing the diversification of perception services in the mobile communication network.

[0068] It should be noted that when a sensing task is performed by multiple sensing nodes, the first network element may send multiple sensing instructions to each of the multiple sensing nodes. The multiple sensing instructions may correspond one-to-one with the multiple sensing nodes. For example, the first network element may send a first sensing instruction to the receiving node of the sensing task and a second sensing instruction to the sending node of the sensing task. The first instruction may be either the first sensing instruction or the second sensing instruction.

[0069] In some embodiments, the first network element may determine one or more of the following information to determine the first instruction: information about multiple sensing nodes participating in the sensing task, whether the first sensing node participates in the sensing task, identity information of the first sensing node, information about other nodes participating in the sensing task other than the first sensing node, etc. The information about the multiple sensing nodes participating in the sensing task may include, for example, one or more of the following information: the number of the multiple sensing nodes, identifiers of the multiple sensing nodes, and identity information of the multiple sensing nodes.

[0070] The first sensing node may send or receive wireless signals according to the first instruction. For example, if the first instruction indicates that the first sensing node is a sending node corresponding to the sensing task, the first sensing node may send wireless signals. Alternatively, if the first instruction indicates that the first sensing node is a receiving node corresponding to the sensing task, the first sensing node may receive wireless signals.

[0071] The present application does not limit the manner in which the sending node sends the wireless signal. For example, the sending node can send the wireless signal by broadcast or unicast. For example, when the sending node can determine the receiving node corresponding to the perception task, the sending node can send the wireless signal to the receiving node by unicast. Alternatively, when the sending node cannot determine the receiving node corresponding to the perception task, the sending node can send the wireless signal by broadcast. As an example, when the first instruction received by the sending node contains the identifier of the receiving node corresponding to the perception task, the sending node can send the wireless signal to the receiving node by unicast according to the identifier of the receiving node.

[0072] In some embodiments, the wireless signal transmitted by the transmitting node can not only be used to implement perception (i.e., associated with a perception task), but can also include one or more of the following information: identification information of the perception task, identification information of the receiving node corresponding to the perception task, and identification information of the transmitting node corresponding to the perception task. When the first sensing node is a transmitting node, the first sensing node can transmit a wireless signal including the above information. When the first sensing node is a receiving node, the first sensing node can receive a wireless signal including the above information.

[0073] In some embodiments, after receiving a wireless signal, the receiving node may perform a corresponding sensing operation based on the wireless signal, i.e., perform a corresponding sensing task. The sensing operation may, for example, include processing the received wireless signal. Executing the corresponding sensing task generates sensing data. The sensing data may include intermediate data generated during the sensing task and / or the results of the sensing task (i.e., sensing results).

[0074] When the first sensing node is a receiving node, the first sensing node may match the received wireless signal with the first instruction and / or information about the first sensing node, so that the first sensing node performs the sensing task according to the first instruction. For example, when the first instruction includes identification information of the sensing task and the wireless signal also includes identification information of the sensing task, the first sensing node may match the first instruction with the identification information of the sensing task in the wireless signal. When the two match, the first sensing node may perform the corresponding sensing task. For another example, when the wireless signal includes identification information of the receiving node, the first sensing node may match the identification information of the first sensing node with the identification information of the receiving node. When the two match, the first sensing node may perform the corresponding sensing task. For another example, when the first instruction includes identification information of the sending node and the wireless signal also includes identification information of the sending node, the first sensing node may match the first instruction with the identification information of the sending node in the wireless signal. When the two match, the first sensing node may perform the corresponding sensing task.

[0075] When the first sensing node is a receiving node, the first sensing node may send a sensing report to the first network element. The sensing report may include one or more of the following information: sensing data generated by performing a sensing task, identification information of the sensing task, identification information of the sending node corresponding to the sensing task, and identification information of the receiving node corresponding to the sensing task. The sensing data generated by performing a sensing task may include intermediate data generated during the sensing task and / or the results of the sensing task. Optionally, the sensing report may also include wireless signals originally obtained by the receiving node.

[0076] To facilitate understanding of the present application, the present application is described in detail below through Example 1 and Example 2.

[0077] Figure 5 is a schematic flowchart of a wireless communication method provided in Example 1 or Example 2. The method shown in Figure 5 may include steps S510 to S550. The method shown in Figure 5 may be performed by an SF, a receiving node, and a sending node. Either the receiving node or the sending node may be the first sensing node described above. The receiving node and the sending node may correspond to the same sensing task. The receiving node and the sending node may be determined by step S510 in Figure 5.

[0078] Example 1

[0079] The following describes in detail Example 1 provided in this application in conjunction with Figure 5.

[0080] In step S510, SF determines the sending node and receiving node corresponding to the sensing task.

[0081] For example, SF determines one node (terminal device or access network device) as a perception signal sending node, and another node (terminal device or access network device) as a perception signal receiving node.

[0082] Step S520, SF sends a first perception instruction to the receiving node.

[0083] The first sensing instruction includes the following information: the identity of the node receiving the first sensing instruction is the receiving node, the sensing task ID, and the identifier of the sending node. The sensing task ID is assigned by the SF.

[0084] Step S530, SF sends a second perception instruction to the sending node.

[0085] The second perception instruction includes the following information: the identity of the node receiving the second perception instruction is the sending node, the perception task ID, and the identifier of the receiving node.

[0086] In step S540, the sending node sends a wireless signal, and correspondingly, the receiving node receives the wireless signal.

[0087] The sending node may send the wireless signal in the form of broadcast or unicast to the receiving node. Taking the unicast wireless signal transmission method as an example, the sending node may send the wireless signal to the receiving node in the form of unicast based on the identifier of the receiving node contained in the second sensing instruction received in step S530. As an example, if the second sensing instruction contains the identifier of the receiving node, the sending node sends the wireless signal to the receiving node in the form of unicast; if the second sensing instruction does not contain the identifier of the receiving node, the sending node sends the wireless signal to the receiving node in the form of broadcast.

[0088] Optionally, the wireless signal may carry a sensing task ID and / or an identifier of a receiving node.

[0089] Optionally, the receiving node can perform the following operations: match whether the perception task ID carried in the received wireless signal is the perception task ID received in step S520; match whether the identifier of the receiving node carried in the received wireless signal is its own identifier; match the sending node of the received wireless signal to the node corresponding to the identifier of the sending node received in step S520.

[0090] Step S550: The receiving node sends the perception report to the SF.

[0091] A perception report may include one or more of the following: the original wireless signal, intermediate data obtained by the receiving node based on further processing of the obtained wireless signal, and a perception result obtained by further processing of the obtained wireless signal. The perception report may also carry one or more of the following: a perception task identifier, a transmitting node identifier, and a receiving node identifier.

[0092] Example 2

[0093] The following describes in detail Example 2 provided in this application in conjunction with Figure 5.

[0094] The main difference between Example 2 and Example 1 is that in Example 2, the perception instruction sent by the SF to the perception node does not include the identifier of the other node (i.e., the opposite perception node). In other words, the perception node can know its own identity information, but does not know the information of the opposite perception node. Another difference between Example 2 and Example 1 is that when the sending node sends a wireless signal, the sent wireless signal may not carry the receiving node information. For example, the wireless signal may carry the perception task identification information and the sending node information. The sending node information may include one or more of the following: the identity information of the sending node, and the sending node identifier.

[0095] In step S510, SF determines the sending node and receiving node corresponding to the sensing task.

[0096] For example, SF determines one node (terminal device or access network device) as a perception signal sending node, and another node (terminal device or access network device) as a perception signal receiving node.

[0097] Step S520, SF sends a first perception instruction to the receiving node.

[0098] The first sensing instruction includes the following information: the identity of the node receiving the first sensing instruction is the receiving node, and the sensing task ID, wherein the sensing task ID is assigned by the SF.

[0099] Step S530, SF sends a second perception instruction to the sending node.

[0100] The second perception instruction includes the following information: the identity of the node receiving the second perception instruction is the sending node, and the perception task ID.

[0101] Step S540: According to the second sensing instruction, the sending node sends a wireless signal, and correspondingly, the receiving node receives the wireless signal.

[0102] The sending node can send wireless signals in the form of broadcast. The wireless signals sent by the sending node can carry the sensing task ID and the sending node information. The sending node information can include, for example, the identity information of the sending node and the sending node identifier.

[0103] Optionally, the receiving node may match whether the sensing task ID carried in the received wireless signal is the sensing task ID received in step S520.

[0104] Step S550: The receiving node sends the perception report to the SF.

[0105] The perception report may include one or more of the following: the original wireless signal, intermediate data obtained by further processing the obtained wireless signal, and the perception result obtained by further processing the obtained wireless signal. The perception report may also carry a perception task identifier and / or a sending node identifier.
