[0191] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0192] When describing the embodiments of the present application, some concepts used in the following description are first explained.

[0193] 1. Communication perception fusion

[0194] Communication and perception fusion refers to the unified design of communication and perception functions through joint design of air interface and protocol, reuse of time-frequency and space resources, sharing of hardware equipment, etc., so that wireless network can realize perception function while performing communication interaction, thereby improving the overall performance and service capabilities of the network. Wireless perception is a technology that uses wireless signals to obtain characteristic information of the environment and / or objects in the environment (such as shape, size, direction, speed, position, distance between objects or relative motion, etc.). Wireless perception services rely on the analysis of transmission, reflection and scattering of wireless perception signals. As part of the wireless communication network, wireless perception services provide the possibility of enhancing the use of telecommunications infrastructure in areas such as object detection and tracking, environmental monitoring and human motion monitoring. Wireless perception services provide inputs for various vertical fields (including drones, smart homes, vehicle-to-everything (V2X) and factories), and specific use cases are as follows:

[0195] For object and intruder detection in predefined security areas around smart homes, highways, railways, factories, and critical infrastructure;

[0196] Collision avoidance and trajectory tracking for drones, vehicles, and automated guided vehicles;

[0197] automatic steering and navigation;

[0198] Public safety search and rescue;

[0199] rainfall monitoring and flooding;

[0200] Health and exercise monitoring.

[0201] In the perception-related process, the base station is involved in the functions of determining the perception signal configuration, sending the perception signal, and receiving the perception signal. In the prior art, the base station, as a logical node, implements all communication-related functions and perception-related functions. The development of the base station requires the development of both the communication function and the perception function, which leads to the high complexity of base station development, resulting in slow base station service launch and complex service updates.

[0202] The embodiments of the present application provide a communication-aware fused information transmission method, apparatus, and network device to solve the problem of complex business updates caused by the existing communication-aware architecture.

[0203] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0204] like Figure 1 As shown, an embodiment of the present application provides a communication perception fusion information transmission method, which is applied to a perception logical node and specifically includes the following steps:

[0205] Step 101: A sensing logical node transmits first information to a first logical node through a first interface, where the first information is information related to a sensing function.

[0206] The sensing logical node and the first logical node are both independent logical nodes in a wireless access network node;

[0207] The first interface includes at least one of the following:

[0208] A point-to-point interface between the sensing logical node and the first logical node;

[0209] A service-based interface of the perception logical node;

[0210] A service-based interface of the first logical node.

[0211] In this embodiment, the perception logical node and the first logical node are both independent logical nodes in the wireless access network node, that is, the perception logical node and the first logical node are independent and separate logical nodes. The perception logical node is a logical node that carries, supports, or implements perception-related functions, such as perception task management functions, perception data processing functions, etc. The "perception logical node" is only an exemplary name for the logical node, and can also be named by any other name, such as perception control logical node, perception management logical node, etc., which is not limited here.

[0212] The first logical node may be another perception logical node that carries the perception function, or may be a logical node that carries communication-related functions. The first logical node may refer to one or more logical nodes; the first interface may refer to one or more interfaces. In the case where the first logical node is multiple logical nodes, the perception logical node may transmit information with multiple first logical nodes through one first interface, or may transmit information with one first logical node through one first interface. The perception logical node may transmit information with multiple first logical nodes through multiple first interfaces, or may transmit information with one first logical node through multiple first interfaces.

[0213] Optionally, the first logical node may include at least one of the following:

[0214] A logical node that carries the terminal wireless connection control function;

[0215] Logical node that carries terminal management functions;

[0216] A logical node that carries terminal capability management functions;

[0217] Logical node that carries the wireless sensing resource scheduling function;

[0218] A logical node that carries the function of sending perception signals;

[0219] A logical node that carries the sensing signal receiving function;

[0220] Logical node that carries third-party wireless sensing functions;

[0221] Logical node that carries radio resource management functions;

[0222] Logical node that carries the terminal data transmission function;

[0223] A logical node that carries the terminal control plane data transmission function;

[0224] A logical node that carries the terminal user plane data transmission function.

[0225] It should be noted that the first logical node may be any one or more of the above logical nodes. In the embodiment of the present application, the first logical node only represents the name of the logical node that transmits the first information to the sensing logical node, and does not specifically refer to a certain logical node. The first interface is a general term for the interface between the sensing logical node and the first logical node, and may include one interface or multiple interfaces, for example: interface 1, interface 2, interface 3..., that is, the first interface does not specifically refer to a certain interface, nor does it specifically refer to the interface between the sensing logical node and a specific logical node.

[0226] Among them, the first logical node can also be a base station-central unit (base station-Central Unit, base station-CU), a base station-CU-control plane (base station-CU-control Plane, base station-CU-CP), a base station-CU-user plane (base station-CU-user Plane, base station-CU-UP), a base station-distributed unit (base station-Distributed Unit, base station-DU), a base station-active antenna unit (base station-Active Antenna Unit, base station-AAU), a base station-radio unit (base station-Radio Unit, base station-RU), and the perception logical node and these logical nodes are independent and separate logical nodes.

[0227] The first interface may be a point-to-point interface between the sensing logical node and the first logical node, such as Figure 2 As shown, each first logical node can carry one or more communication functions, and each first logical node has a first interface with the sensing logical node, such as interface 1, interface 2, etc. It should be noted that the sensing logical node can only have Figure 2 Some interfaces in .

[0228] Optionally, multiple functions may be hosted on the same logical node. Figure 2 In actual implementation, one possibility is that one function corresponds to one logical node, that is, one logical node carries one function. Another possibility is that multiple functions correspond to one logical node, that is, one logical node carries multiple functions.

[0229] An example of a logical node carrying multiple functions: for example, two or more logical nodes carrying the user equipment (UE) wireless connection control function or the UE wireless connection management function, the logical node carrying the UE capability management function, the logical node carrying the wireless resource management function, the logical node carrying the wireless perception resource scheduling function, the logical node carrying the UE control plane data transmission function, and the logical node carrying the UE user plane data transmission function may be the same base station logical node. Another example: two or more logical nodes carrying the wireless resource management function, the logical node carrying the UE data transmission function, the logical node carrying the perception signal sending function, the logical node carrying the perception signal receiving function, and the logical node carrying the third-party wireless perception function may be the same base station logical node.

[0230] When a logical node carries multiple functions, Figure 2 Some interfaces in the same logical interface are the same logical interface. For example, when the logical node carrying the UE radio connection control / management function and the logical node carrying the radio resource management function are the same logical node, the first logical node carries the above two functions, so interface 1 and interface 6 are the same interface, namely the first interface.

[0231] Optionally, the first interface may also be a service-based interface of a perception logical node or a first logical node. A first logical node or a perception logical node can provide services to other authorized network functions through a service-based interface, and other authorized network functions can access its services. The service of the first logical node or the perception logical node is a function that is exposed to other authorized network functions through a service-based interface. The service-based interface of the first logical node or the perception logical node is an interface for calling the service operation of the first logical node or the perception logical node. The first logical node or the perception logical node may also be equivalent to a network function. In the case where the first interface is a service-based interface, it is only necessary to define a service-based interface of a network function, and there is no need to define an interface between two specific network functions.

[0232] In the embodiment of the present application, by defining the interface between the perception logical node and the first logical node, the perception logical node and the first logical node are used as independent wireless access network nodes for information transmission. The communication logical node and the perception logical node can be deployed separately according to different needs for communication and perception, and the communication function and the perception function of the access network device can be developed separately, reducing the complexity of network device development, thereby speeding up the launch of network services. When either the communication or perception function needs to be updated, only one logical node needs to be updated, reducing the complexity of service updates and facilitating the independent evolution of the two functions.

[0233] Optionally, the perception logical node and the first logical node belong to the same wireless access network node.

[0234] In this embodiment, the perception logical node and the first logical node may be independent and separate logical nodes in the same wireless access network node. For example, the perception logical node and the communication logical node of the terminal wireless connection control function are two independent nodes in a base station, and information transmission is achieved between the two nodes through a defined first interface.

[0235] Optionally, the first information includes at least one of the following:

[0382] After receiving the data unit containing the information to be sent to the UE, the logical node carrying the UE user plane data transmission function sends it to the UE. After receiving the data unit containing the information to be sent by the UE to the perception logical node, the logical node carrying the UE user plane data transmission function sends it to the perception logical node.

[0383] It should be noted that, in one or more of the above embodiments, when the sensing logical node transmits the first information to different first logical nodes through the first interface, the first information may be the same information or different information, for example Figure 2 As shown:

[0384] The perception logical node obtains the relevant information of the terminal from the first logical node through interface 1;

[0388] The sensing logical node sends the sensing task related information to the first logical node through the interface 5 and / or receives the sensing task related information sent by the first logical node.

[0389] The perception logical node negotiates with the first logical node through interface 6 for wireless resources used for perception, for example: wireless perception resource policy information; information of the logical node that carries the perception signal sending function in the wireless access network node; information of the logical node that carries the perception signal receiving function in the wireless access network node; information of the logical node that carries the third-party wireless perception function in the wireless access network node.

[0391] The perception logical node sends the first data unit to the logical node carrying the UE control plane data transmission function through interface 8 or receives the second data unit through interface 8.

[0392] The perception logical node sends the first data unit to the logical node carrying the UE user plane data transmission function through interface 9 or receives the second data unit through interface 9.

[0393] The above interfaces 1 to 9 may be different interfaces, or some of them may be the same interface. The perception process completed based on the above interfaces is as follows:

[0394] 1) The sensing logical node obtains a sensing task through a first interface. The sensing task includes sensing information of a sensing object to be determined. In a possible manner, the first interface is a point-to-point interface between the sensing logical node and another sensing logical node.

[0395] The sensing logical node needs to complete a sensing task when it is triggered, and the sensing task includes sensing information of the sensing object to be determined. The sensing logical node may receive sensing task information from another sensing logical node on interface 5. In this case, the first interface between the sensing logical node and the other sensing logical node is the interface 5.

[0396] 2) The sensing logical node determines a sensing subtask according to the sensing information of the sensing object to be determined, and sends the sensing subtask information to another sensing logical node through a first interface. The first interface is a point-to-point interface between the sensing logical node and another sensing logical node.

[0397] For example, the sensing logical node sends sensing subtask information to another sensing logical node on interface 5. The other sensing logical node determines the sensing information of the sensing object required to be determined for the sensing subtask. The other sensing logical node sends the sensing information of the sensing object to the sensing logical node on interface 5. In this case, the first interface between the sensing logical node and the other sensing logical node is the interface 5.

[0398] 3) The sensing logical node obtains the relevant information of the first logical node through the first interface. The first interface is a point-to-point interface between the sensing logical node and the first logical node.

[0399] For example, the perception logical node requests the relevant information of the logical node from one or more of the following logical nodes on interface 4: the logical node carrying the perception signal sending function, the logical node carrying the perception signal receiving function, and the logical node carrying the third-party wireless perception function. At least one of the logical node carrying the perception signal sending function, the logical node carrying the perception signal receiving function, and the logical node carrying the third-party wireless perception function responds to the perception logical node on interface 4 with the relevant information of the logical node. In this case, the first interface between the perception logical node and the logical node carrying the perception signal sending function, the logical node carrying the perception signal receiving function, or the logical node carrying the third-party wireless perception function is the interface 4.

[0400] 4) The sensing logical node obtains the relevant information of the terminal through the first interface. The first interface is a point-to-point interface between the sensing logical node and the first logical node.

[0401] For example, the perception logical node requests UE related information from the logical node carrying the UE radio connection control function or the logical node carrying the UE radio connection management function on interface 1. The logical node carrying the UE radio connection control function or the logical node carrying the UE radio connection management function responds UE related information to the perception logical node on interface 1. In this case, the first interface between the perception logical node and the logical node carrying the UE radio connection control function or the logical node carrying the UE radio connection management function is the interface 1.

[0402] 5) The sensing logical node determines one or more of the following sensing units according to the second information: a sensing unit that sends a sensing signal, a sensing unit that receives a sensing signal, and a sensing unit that performs third-party wireless sensing.

[0403] The second information includes one or more of the following: perception information of the perception object to be determined; UE related information; information about the logical node that carries the perception signal sending / receiving function; and information about the third-party wireless perception function.

[0404] 6) When the sensing unit that sends the sensing signal or receives the sensing signal or performs third-party wireless sensing is a UE, the sensing logical node obtains the relevant information of the terminal through the first interface, and / or the sensing logical node obtains the terminal capability information through the first interface. The first interface is a point-to-point interface between the sensing logical node and the first logical node.

[0405] For example, the sensing logical node requests UE related information from the logical node carrying the UE radio connection control function or the logical node carrying the UE radio connection management function on interface 1. The logical node carrying the UE radio connection control function or the logical node carrying the UE radio connection management function responds UE related information to the sensing logical node on interface 1.

[0406] The sensing logical node requests UE capability information from the logical node carrying the UE capability management function over interface 2. The logical node carrying the UE capability management function responds with UE capability information to the sensing logical node over interface 2.

[0407] In this case, the first interface between the sensing logical node and the logical node carrying the UE radio connection control function or the logical node carrying the UE radio connection management function is the interface 1. The first interface between the sensing logical node and the logical node carrying the UE capability management function is the interface 2.

[0408] 7) When the sensing unit that sends the sensing signal or receives the sensing signal or performs third-party wireless sensing is a base station, the sensing logical node obtains at least one of the following through a first interface: relevant information of the base station that sends the sensing signal, relevant information of the base station that receives the sensing signal, and relevant information of the base station that performs third-party wireless sensing. The first interface is a point-to-point interface between the sensing logical node and the first logical node.

[0409] For example, the perception logical node requests relevant information from the logical node carrying the perception signal sending function, the perception signal receiving function, or the third-party wireless perception function on interface 4. The logical node carrying the perception signal sending function, the perception signal receiving function, or the third-party wireless perception function responds with relevant information to the perception logical node on the fourth interface.

[0410] In this case, the first interface between the perception logical node and the logical node carrying the perception signal sending function, or carrying the perception signal receiving function, or carrying the third-party wireless perception function is the interface 4.

[0411] 8) In case of needing to send a sensing signal and / or receive a sensing signal, the sensing logical node determines the need for wireless sensing resources.

[0412] Among them, the perception logical node can determine the demand for wireless perception resources based on one or more of the following: perception information of the perception object to be determined, relevant information of the UE, UE capability information, and relevant information of the logical node carrying the perception signal sending function or the perception signal receiving function.

[0413] 9) When it is necessary to send a sensing signal and / or receive a sensing signal, the sensing logical node sends wireless sensing resource scheduling control information to the first logical node through a first interface. The first interface is a point-to-point interface between the sensing logical node and the first logical node.

[0414] For example, the sensing logical node sends wireless sensing resource scheduling control information to the logical node carrying the wireless sensing resource scheduling function on interface 3. The wireless sensing resource scheduling control information is determined according to the demand for wireless sensing resources. The logical node carrying the wireless sensing resource scheduling function responds to the sensing logical node with wireless sensing resource scheduling information on interface 3. The wireless sensing resource scheduling information may be resource information where the sensing signal is located.

[0415] In this case, the first interface between the sensing logical node and the logical node carrying the wireless sensing resource scheduling function is the interface 3.

[0416] 10) When the base station needs to send or receive a perception signal, the perception logical node sends perception signal sending control information and / or perception signal receiving control information to the first logical node through a first interface. The first interface is a point-to-point interface between the perception logical node and the first logical node.

[0417] For example, the sensing logical node sends the sensing signal sending control information to the logical node carrying the sensing signal sending function on interface 4. The sensing logical node sends the sensing signal receiving control information to the logical node carrying the sensing signal receiving function on interface 4. The sensing signal sending control information and / or the sensing signal receiving control information include the resource information where the sensing signal is located. The logical node carrying the sensing signal sending function sends the sensing signal on the resource where the sensing signal is located. The logical node carrying the sensing signal receiving function receives the sensing signal on the resource where the sensing signal is located.

[0418] In this case, the first interface between the perception logical node and the logical node carrying the perception signal sending function or the logical node carrying the perception signal receiving function is the interface 4.

[0419] 11) When the UE needs to send or receive a perception signal, the perception logical node sends perception signal sending control information and / or perception signal receiving control information to the UE. The perception signal sending control information and / or perception signal receiving control information includes resource information where the perception signal is located. The UE sends and / or receives the perception signal on the resource where the perception signal is located.

[0420] Optionally, the sensing logical node sends a data unit containing information to be sent to the UE to the first logical node through the first interface; the first logical node sends the data unit containing the information to be sent to the UE to the terminal. The first interface is a point-to-point interface between the sensing logical node and the first logical node. The information to be sent to the UE includes sensing signal sending control information and / or sensing signal receiving control information.

[0421] Specifically, the sensing logical node sends the data unit containing the information to be sent to the UE to the logical node carrying the UE data transmission function over the interface 7, and the logical node carrying the UE data transmission function sends the data unit containing the information to be sent to the UE to the UE. In this case, the first interface between the sensing logical node and the logical node carrying the UE data transmission function is the interface 7.

[0422] Alternatively, the sensing logical node sends the data unit containing the information to be sent to the UE to the logical node carrying the UE control plane data transmission function over the interface 8, and the logical node carrying the UE control plane data transmission function sends the data unit containing the information to be sent to the UE to the UE. In this case, the first interface between the sensing logical node and the logical node carrying the UE control plane data transmission function is the interface 8.

[0423] Alternatively, the sensing logical node sends the data unit containing the information to be sent to the UE to the logical node carrying the UE user plane data transmission function over interface 9, and the logical node carrying the UE user plane data transmission function sends the data unit containing the information to be sent to the UE to the UE. In this case, the first interface between the sensing logical node and the logical node carrying the UE user plane data transmission function is the interface 9.

[0424] 12) When the base station needs to send a sensing signal or receive a sensing signal or perform third-party wireless sensing, the sensing logical node sends sensing data processing control information to the first logical node through the first interface. The first interface is a point-to-point interface between the sensing logical node and the first logical node.

[0425] For example, the perception logical node sends the perception data processing control information to the logical node carrying the perception signal sending function, the logical node carrying the perception signal receiving function, or the logical node carrying the third-party wireless perception function on interface 4. In this case, the first interface between the perception logical node and the logical node carrying the perception signal sending function, the logical node carrying the perception signal receiving function, or the logical node carrying the third-party wireless perception function is the interface 4.

[0426] The logical node carrying the perception signal sending / receiving function determines the perception data to be output indicated in the perception data processing control information according to one or more of the following information: received data of the perception signal and input perception data.

[0427] The logical node carrying the third-party wireless sensing function determines the sensing data to be output indicated in the sensing data processing control information according to one or more of the following: data obtained by the third-party wireless sensing, and input sensing data.

[0428] The logical node carrying the perception signal sending / receiving function and the third-party wireless perception function sends the output perception data to the perception data receiving logical node indicated in the perception data processing control information.

[0429] 13) When the UE is required to send a perception signal or receive a perception signal or perform third-party wireless perception, the perception logical node sends perception data processing control information to the UE.

[0430] Optionally, the sensing logical node sends a data unit containing information to be sent to the UE to the first logical node through a first interface; the first logical node sends the data unit containing the information to be sent to the UE to the terminal. The first interface is a point-to-point interface between the sensing logical node and the first logical node. The information to be sent to the UE includes sensing data processing control information.

[0431] For example, the sensing logical node can send information to the UE through interface 7, interface 8 or interface 9, as described in 11), which will not be repeated here. In this case, the first interface between the sensing logical node and the logical node carrying the UE data transmission function is the interface 7; the first interface between the sensing logical node and the logical node carrying the UE control plane data transmission function is the interface 8; the first interface between the sensing logical node and the logical node carrying the UE user plane data transmission function is the interface 9.

[0432] The UE determines the perception data to be output indicated in the perception data processing control information according to one or more of the following: received data of a perception signal, data obtained by third-party wireless perception, and input perception data.

[0433] The UE sends the outputted perception data to the perception data receiving logical node indicated in the perception data processing control information.

[0434] 14) The sensing logical node receives the sensing data sent by the first logical node through a first interface. The first interface is a point-to-point interface between the sensing logical node and the first logical node.

[0435] For example, the perception logical node may receive perception data from a logical node carrying a perception signal sending function, a logical node carrying a perception signal receiving function, or a logical node carrying a third-party wireless perception function on interface 4. The perception logical node determines the perception information of the perception object according to the perception data. In this case, the first interface between the perception logical node and the logical node carrying a perception signal sending function, the logical node carrying a perception signal receiving function, or the logical node carrying a third-party wireless perception function is interface 4.

[0436] 15) The perception logical node receives the perception data from the UE. The perception logical node determines the perception information of the perception object according to the perception data. The first logical node receives a data unit containing information to be sent to the perception logical node from the terminal; the first logical node sends the data unit containing the information to be sent to the perception logical node to the perception logical node through the first interface. The first interface is a point-to-point interface between the perception logical node and the first logical node. The information to be sent to the perception logical node includes the perception data.

[0437] For example, the perception logical node may receive information from the UE via interface 7, interface 8, or interface 9, which will not be described in detail here.

[0438] 16) In the case where the sensing task comes from another sensing logical node, the sensing logical node sends the sensing information of the sensing object to the other sensing logical node through a first interface. The first interface is a point-to-point interface between the sensing logical node and the other sensing logical node.

[0439] For example, the sensing logical node sends the sensing information of the sensing object to another sensing logical node on interface 5. In this case, the first interface between the sensing logical node and the other sensing logical node is the interface 5.

[0440] It should be noted that each of the above operations is optional.

[0441] Service-based interfaces and point-to-point interfaces are two different methods for modeling interactions between architectural entities. The point-to-point interface between the perception logical node and the first logical node may be replaced by a service-based interface of the perception logical node and / or a service-based interface of the first logical node. In an embodiment of the present application, the first interface may also be a service-based interface of the perception logical node or the first logical node. In this case, the interfaces between the perception logical node and different first logical nodes may be different, for example, the first interface is a service-based interface of each first logical node. The interfaces between the perception logical node and different first logical nodes may also be the same, for example, the first interface is a service-based interface of the perception logical node.

[0456] In some implementations, multiple functions may be hosted on the same first logical node, that is, one first logical node hosts multiple functions. In the case where multiple functions may be hosted on the same first logical node, the same first logical node provides multiple service operations through a service-based interface.

[0483] Alternatively, the sensing logical node requests UE user plane data transmission through a service-based interface of a logical node carrying a UE user plane data transmission function. The request information includes the data unit of the information to be sent to the UE. The logical node carrying the UE user plane data transmission function sends the data unit containing the information to be sent to the UE to the UE.

[0484] 12) When the base station is required to send a sensing signal or receive a sensing signal or perform third-party wireless sensing, the sensing logical node provides sensing data through a service-based interface request of the first logical node.

[0485] For example, the sensing logical node provides the sensing data through a service-based interface request of a logical node carrying a sensing signal sending function, a logical node carrying a sensing signal receiving function, or a logical node carrying a third-party wireless sensing function. The request information indicates the sensing data processing control information.

[0486] The logical node carrying the perception signal sending function or the perception signal receiving function determines the perception data to be output indicated in the perception data processing control information according to one or more of the following: the received data of the perception signal and the input perception data. The logical node carrying the third-party wireless perception function determines the perception data to be output indicated in the perception data processing control information according to one or more of the following: the data obtained by the third-party wireless perception and the input perception data.

[0487] The logical node carrying the perception signal sending function, or the logical node carrying the perception signal receiving function, or the logical node carrying the third-party wireless perception function responds to the output perception data to the perception data receiving logical node indicated in the perception data processing control information on its service-based interface.

[0488] 13) When the UE needs to send a perception signal or receive a perception signal or perform third-party wireless perception, the perception logical node sends perception data processing control information to the UE. Optionally, the perception logical node sends a data unit containing information to be sent to the UE to the first logical node through the service-based interface of the first logical node; the first logical node sends the data unit containing the information to be sent to the UE to the terminal. The information to be sent to the UE includes the perception data processing control information. The way in which the perception logical node sends information to the UE is as described in 11), which will not be repeated here.

[0489] The UE determines the perception data to be output indicated in the perception data processing control information according to one or more of the following: received data of a perception signal, data obtained by third-party wireless perception, and input perception data.

[0490] The UE sends the outputted perception data to the perception data receiving logical node indicated in the perception data processing control information.

[0491] 14) The sensing logical node receives the sensing data sent by the first logical node through the service-based interface of the first logical node.

[0492] For example, the perception logical node obtains its perception data through the service-based interface of the logical node carrying the perception signal sending function, the logical node carrying the perception signal receiving function, or the logical node carrying the third-party wireless perception function. The perception logical node determines the perception information of the perception object according to the perception data.

[0493] 15) The sensing logical node receives the sensing data from the UE.

[0494] Optionally, the first logical node receives a data unit containing information to be sent to the sensing logical node from the terminal; the sensing logical node receives the data unit containing information to be sent to the sensing logical node through a service-based interface of the first logical node. The data unit containing information to be sent to the sensing logical node includes the sensing data.

[0495] For example, the perception logical node determines the perception information of the perception object according to the perception data. The perception logical node obtains the information from the UE through the service-based interface of the logical node carrying the UE data transmission function, or the service-based interface of the logical node carrying the UE control plane data transmission function, or the service-based interface of the logical node carrying the UE user plane data transmission function, which will not be repeated here.

[0496] 16) In the case that the sensing task comes from another sensing logical node, the sensing logical node sends the sensing information of the sensing object to the other sensing logical node through a service-based interface.

[0497] For example: A sensing logical node responds to the sensing information of a sensing object on its service-based interface.

[0498] It should be noted that each of the above operation steps is optional. The service-based interface and the point-to-point interface are two different methods for modeling the interaction between architecture entities. The service-based interface of the perception logical node and / or the service-based interface of the first logical node can be replaced by a point-to-point interface between the perception logical node and the first logical node.

[0508] The logical node that carries the UE user plane data transmission function may be a base station-CU or a base station-CU-UP.

[0509] It should be noted that the logical node in the wireless access network node in the embodiment of the present application may also be referred to as a base station network function, a wireless network function or a network function.

[0590] Sending a first data unit to the first logical node through the second interface, where the first data unit is used to indicate information sent by the sensing logical node to the terminal;

[0591] A second data unit sent by the first logical node is received through the second interface, where the second data unit is used to indicate information sent by the terminal to the perception logical node.

[0592] In this embodiment, the second interface is an interface between the perception logical node and the first logical node when the perception logical node is a network function in the core network. The first logical node is a logical node in a wireless access network node, and when the first logical node includes multiple logical nodes, each logical node is independent and separated.

[0593] Taking the example that the perception logical node is the first network function in the core network, there is an interface 10 between the first network function and the logical node that carries the UE wireless connection control / management function, and the information content of the interaction on interface 10 is the same as the content of the interaction on interface 1.

[0594] The first network function has an interface 11 with the logical node carrying the UE capability management function, and the content of the interaction on interface 11 is the same as the content of the interaction on interface 2. The first network function has an interface 12 with the logical node carrying the wireless perception resource scheduling function, and the content of the information exchanged on interface 12 is the same as the content of the interaction on interface 3.

The first network function has an interface 16 with the logical node carrying the UE data transmission function, and the content of the interaction on interface 16 is the same as the content of the interaction on interface 7. The first network function has an interface 17 with the logical node carrying the UE control plane data transmission function, and the content of the interaction on interface 17 is the same as the content of the interaction on interface 8. The first network function has an interface 18 with the logical node carrying the UE user plane data transmission function, and the content of the interaction on interface 18 is the same as the content of the interaction on interface 9. The first network function may also interact with each first logical node through its own service-based interface or through the service-based interface of each first logical node.

[0595] The UE capability management function may also be carried by a network function in the core network, for example, a second network function. Accordingly, an interface 19 is provided between the second network function and the perception logical node, and the content of the interaction on the interface 19 is the same as the content of the interaction on the interface 2. The second network function may also interact with the perception logical node through a service-based interface between the second network function and the perception logical node. Other functions carried by the first logical node may also be carried by a network function in the core network, which is similar to the above content and will not be described in detail here.

[0596] It should be noted that, in the case where the perception logical node is a network function in the core network, the embodiment of information transmission for realizing communication perception fusion is similar to the embodiment in which the perception logical node is a logical node in a wireless access network node, except that the interface for transmitting information is different, that is, when the perception logical node is a logical node in a wireless access network node, the first information is transmitted between the perception logical node and the first logical node through the first interface; when the perception logical node is a network function in the core network, the first information is transmitted between the perception logical node and the first logical node through the second interface. In this embodiment, the specific implementation steps of transmitting information through the second interface are the same as the execution steps of transmitting information through the first interface, and the information transmitted is the same. The first interface in the above embodiment can be replaced by the second interface to obtain an embodiment in which the perception logical node is a network function in the core network, which will not be described in detail here.

[0597] The following example illustrates a method for implementing the perception function when both the perception logical node and the first logical node are independent logical nodes in the wireless access network node.

[0598] Example 1: An architecture of a base station supporting sensing-related functions such as Figure 4 shown.

[0599] Among them, the first base station logical node carries the UE wireless connection control function / UE wireless connection management function. The second base station logical node carries the wireless perception resource scheduling function, the perception signal sending function, the perception signal receiving function, and the UE data transmission function. UE data transmission functions include: ARQ error correction function, service data packet segmentation and reassembly function, MAC, and some or all of the physical layer functions of the base station. Some physical layer functions can be some functions of the high-level physical layer. The perception logical node carries the perception task management function, the perception data processing function, and the perception unit scheduling function. Optionally, the perception logical node can also include some UE data transmission functions, such as: data encryption / decryption function, data integrity protection / verification function. There is an interface A1 between the perception logical node and the first base station logical node. There is an interface A2 between the perception logical node and the second base station logical node. The first base station logical node and the second base station logical node have an A3 interface.

[0600] It should be noted that this embodiment does not limit the base station to include other logical nodes. For example, the base station also includes a logical node that carries the UE user plane data transmission function, such as a base station-CU-UP, and there is an interface between the logical node and the second base station logical node. For another example, the base station also includes a logical node that carries the wireless communication resource scheduling function and the UE data transmission function, and the logical node does not support the perception signal sending function and the perception signal receiving function, such as a base station-DU that does not support the perception signal sending function and the perception signal receiving function.

[0601] When the perception logical node needs to enable the system to obtain the perception information of the perception object required for a perception task, the following operations can be performed.

[0602] 1) The sensing logical node requests the first base station logical node for information of UEs that are in a given location range and in a wireless connection state.

[0610] 9) The second base station logical node sends a perception signal on the resources scheduled by the wireless perception resources.

[0611] 10) The UE receives the perception signal according to the perception signal reception control information. The UE receives the perception signal on the resource scheduled by the wireless perception resource. The UE receives data according to the perception signal and determines the perception data that complies with the perception data processing control information.

[0612] 11) The UE sends the sensing data to the sensing logical node. Specifically, the UE may send the sensing data to the sensing logical node through the second base station logical node.

[0613] It should be noted that the above operations are not limited in order. The information sent in different steps of the above operations can be sent in the same message or in different messages.

[0614] The above step 6) can also be replaced by the second base station logical node sending the sensing signal reception control information to the UE. Before the second base station logical node sends the sensing signal reception control information to the UE, the sensing logical node sends the identifier of the UE to the second base station logical node.

[0615] The first base station logical node may be a base station-CU-CP. The second base station logical node may be a base station-DU.

[0616] Example 2: An architecture of a base station supporting sensing-related functions Figure 5 shown.

[0617] Among them, the third base station logical node carries the UE wireless connection control / management function. The fourth base station logical node carries the wireless perception resource scheduling function, the perception signal sending function, the perception signal receiving function, and the UE data transmission function. UE data transmission functions include: ARQ error correction function, service data packet segmentation and reassembly function, MAC, and some or all of the physical layer functions of the base station. Some physical layer functions may be some functions of the high-level physical layer. The perception logical node carries the perception task management function, the perception data processing function, and the perception unit scheduling function.

Optionally, the service operation provided by the fourth base station logical node also includes UE data transmission. The input of the service is a UE identifier, a data unit to be sent to the UE, or a data unit from the UE.

[0621] It should be noted that this embodiment does not limit the base station to include other base station logical nodes. For example, the base station also includes a base station logical node that carries a UE user plane data transmission function, such as a base station-CU-UP.

[0622] When the perception logical node needs to enable the system to obtain the perception information of the perception object required for a perception task, the following operations can be performed.

[0623] 1) The sensing logical node accesses the third base station logical node to provide UE related information service operation. The input of the service operation is a given location range and the UE is in a wireless connection state.

[0624] 2) The third base station logical node responds to the sensing logical node with a UE-related information service operation. The output of the service operation is information about one or more UEs in a given location range and in a wireless connection state. The UE information includes the UE identifier and may also include the UE location.

[0625] 3) The sensing logical node determines a UE from the one or more UEs to participate in sensing, for example, determining the UE as a receiver of the sensing signal.

[0628] 6) The sensing logical node sends sensing signal reception control information to the UE.

Specifically, the sensing logical node may send the sensing signal reception control information to the UE through the fourth base station logical node. The sensing logical node may access the UE data transmission service operation of the fourth base station logical node. The input of the service operation is the UE identifier and the data unit carrying the sensing signal reception control information to be sent to the UE.

[0629] 7) The perception logical node sends the perception data processing control information to the UE.

[0644] 4) After receiving the first data unit through one or more of PHY downlink reception, MAC downlink reception, and RLC receiving end processing, the UE processes the first data unit to obtain the perception data processing control information. For example, the first data unit undergoes one or more of the following processing: decryption, integrity verification, and PDCP receiving end processing.

Data units containing information exchanged between the sensing logical node and the UE are transmitted on the D1 interface. The sensing logical node and the ninth base station logical node can also interact through a service-based interface, and the sensing logical node transmits data units containing information exchanged between the sensing logical node and the UE through the UE user plane data transmission service operation provided by the ninth base station logical node.

The ninth base station logical node and the tenth base station logical node can also interact through the interface of the base station service, and the ninth base station logical node transmits data units containing information exchanged between the sensing logical node and the UE through the UE data transmission service operation provided by the tenth base station logical node.
