[0003] However, after the terminal enters the sensing area, the base station needs to perform complex calculations to connect the terminal in the sensing area with the target object sensed by the base station. This reduces the analysis efficiency of the base station when analyzing the sensed target object and affects the sensing accuracy of the communication sensing network. Summary of the Invention

[0060] The communication method provided in this application will now be described in detail with reference to the accompanying drawings.

[0061] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0062] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0063] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0064] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0065] To facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish the same or similar items with essentially the same function and effect. Those skilled in the art can understand that the terms "first" and "second" are not intended to limit the quantity or execution order.

[0066] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0067] The principle of communication sensing technology is to perceive the environment through signals from a wireless communication system. Within the sensing area, the communication signals sent by the base station are reflected or scattered after reaching the target object. The base station can analyze the communication signals reflected by the target object, thereby realizing the perception of the target object within the sensing area.

[0068] The advantage of integrated communication and sensing is that it can utilize a single set of base station hardware resources to achieve communication and sensing functions. Compared with other sensing devices such as cameras, communication and sensing have a wider coverage area. Furthermore, after sensing an object, the sensing information can be transmitted to the monitoring party via a wireless network, enabling the monitoring party to take timely warnings and other countermeasures against the sensed object.

[0069] However, after the terminal enters the sensing area, the base station needs to perform complex calculations to connect the terminal in the sensing area with the target object sensed by the base station. This reduces the analysis efficiency of the base station when analyzing the sensed target object and affects the sensing accuracy of the communication sensing network.

[0070] To address the aforementioned technical problems, this application provides a communication method. The idea is as follows: after receiving a first instruction message from a second node instructing the first node to record a trajectory within the sensing area, the first node can send trajectory information to the second node. This allows the second node to know the trajectory record of the first node within the sensing area. Consequently, the second node can connect the target objects sensed by the first and second nodes within the sensing area without performing complex calculations. This helps the second node to further analyze the sensed target objects and improves the sensing accuracy of the communication sensing network.

[0071] The technical solutions provided in this application can be applied to various mobile communication networks, such as 5G new radio (NR) mobile communication networks, time division duplex long term evolution (TD-LTE) mobile communication networks, frequency division duplex long term evolution (FDD-LTE) mobile communication networks, future mobile communication networks, or multiple communication convergence systems, etc. This application does not limit them.

[0072] The embodiments provided in this application will now be described in detail with reference to the accompanying drawings.

[0073] The communication method provided in this application can be applied to, for example... Figure 1 The application environment shown. For example... Figure 1 As shown, the application environment includes: a first node 101 and a second node 102, which are interconnected.

[0074] In some embodiments, the first node 101 can be a device with wireless transceiver capabilities. Exemplary examples include mobile phones, tablets, wearable devices, in-vehicle devices, computers with wireless transceiver capabilities, virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, wireless terminals in self-driving vehicles, and so on. This application does not limit the device form of the first node 101.

[0075] In some embodiments, the second node 102 may be a base station. For example, the second node 102 may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system, etc. The base station may include various network-side devices such as macro base stations, micro base stations, home base stations, wireless remote extensions, reconfigurable intelligent surfaces (RIS), routers, and wireless fidelity (WIFI) devices.

[0076] In some embodiments, the second node 102 is used to provide wireless access services to a plurality of first terminals 101. For example, the second node 102 can provide a service coverage area (also known as a cell). First nodes 101 entering the area can communicate with the second node 102 via wireless signals to receive the wireless access services provided by the second node 102.

[0077] In some embodiments, the second node 102 can send first instruction information to the first node 101, the first instruction information being used to instruct the first node 101 to record a trajectory within the sensing area. The first node 101 can receive the first instruction information sent by the second node 102 and send trajectory information to the second node.

[0078] It should be noted that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0079] See Figure 2 This is a flowchart illustrating a communication method provided in an embodiment of this application. Figure 2 As shown, the communication method provided in this application is applied to a first node, which can be one of the above-mentioned... Figure 1 The first node 101 shown specifically includes the following steps S201 to S202.

[0080] S201, Receive the first instruction information sent by the second node.

[0081] The first instruction information is used to instruct the first node to record its trajectory within the sensing area.

[0082] In some embodiments, when the first node is in an idle state, the first node can receive a system message broadcast by the second node. The system message includes first indication information, that is, the first indication information can be carried in the system message.

[0083] For example, the first indication information may be carried in a system information block (SIB), a remaining minimum system information (RMSI), or a master information block (MIB).

[0084] In some embodiments, when the first node is in a connected state, the second node can send an RRC reconfiguration message to the first node. The RRC reconfiguration message includes first indication information, that is, the first indication information can be carried in the RRC reconfiguration message.

[0085] For example, if the sensing area is a sub-area within the signal coverage area of ​​the second node, the first node may enter the sensing area when moving within the signal coverage area of ​​the second node. The second node can instruct the first node to record its trajectory after entering the sensing area by sending an RRC reconfiguration message to the first node.

[0086] It is understandable that when the first node is in an idle state, the second node cannot obtain the location information of the first node. Therefore, the location information of the sensing area can be indicated by the first indication information so that the first node can determine whether it needs to enter the sensing area.

[0087] In some embodiments, the first indication information includes at least one of the following: sensing area indication information, which indicates the location information of the sensing area; and sensing measurement information, which indicates the information that the trajectory information should be recorded.

[0088] For example, the sensing area indication information may include the central geographic coordinates and coverage radius of the sensing area, or the pitch angle, azimuth angle, and maximum horizontal distance of the sensing area. Sensing measurement information may include at least one of the following: location information; velocity information.

[0089] In some embodiments, after receiving the first indication information sent by the second node, the first node can start trajectory recording when it determines that it has entered the perception area based on the perception area indication information.

[0090] For example, the first node can obtain location information through a satellite positioning system, or based on the location information of a Wi-Fi access point (AP), and record the location information. The satellite positioning system can be a Global Positioning System (GPS), a Global Navigation Satellite System (GNSS), or similar systems.

[0091] In some embodiments, the sensing measurement information further includes a trajectory information update period, which is used to indicate the time interval at which the first node updates its trajectory information.

[0092] In some embodiments, when the sensing measurement information includes position information, velocity information, and trajectory information update cycles, the trajectory information recorded by the first node includes multiple position information and / or multiple velocity information recorded by the first node according to the indication of the trajectory information update cycle.

[0093] In some embodiments, when the first node is in a connected state, the second node can obtain the location information of the first node. Therefore, the second node can directly determine whether the first node is located within the sensing area, and if it determines that the first node has entered the sensing area, instruct the first node to record its trajectory within the sensing area.

[0094] In some embodiments, the first indication information is further used to trigger the first node to perceive unknown objects within the perception area.

[0095] Among them, the unknown object can be an object in the perception area that can be perceived by the second node.

[0096] Understandably, the first node can integrate sensors and corresponding software algorithms, enabling it to possess sensing capabilities. With this capability, the second node can send a first instruction to the first node, triggering it to perceive unknown objects within its sensing area, thus acquiring more comprehensive sensing information.

[0097] For example, the first indication information includes auxiliary perception information, which is used to trigger the first node to perceive unknown objects within the perception area.

[0098] Furthermore, the auxiliary sensing information is also used to indicate at least one of the following: available sensing resources; the type of target to be sensed; and the sensing information to be recorded.

[0099] The available perception resources refer to the resources that the first node can access when perceiving unknown objects within the perception area.

[0100] The types of targets to be perceived may include at least one of the following: drones, pedestrians, automated guided vehicles (AGVs), vehicles, and ships.

[0101] The perception information to be recorded is used to indicate the perception information that the first node should record when perceiving unknown objects in an unknown area. The perception information to be recorded includes at least one of the following: position information and velocity information.

[0102] In some embodiments, where the first indication information is carried in a system message, the system message sent by the second node to the first node is as follows.

The PositionInfo and SpeedInfo included in SensingParameter are used to indicate that the sensing parameters that the first node should record when sensing unknown objects in an unknown area are position information and velocity information.

[0129] In some embodiments, when the first node is in a connected state, the RRC reconfiguration message sent by the second node to the first node is as follows.

PositionInfo and SpeedInfo included in SensingParameter are used to indicate that the sensing parameters that the first node should record when sensing unknown objects in an unknown area are position information and velocity information.

[0156] S202, Send trajectory information to the second node.

[0157] The trajectory information includes the trajectory record of the first node in the sensing area.

[0158] In some embodiments, the trajectory information sent from the first node to the second node includes position information and velocity information. The trajectory information may include multiple pieces of position and / or velocity information, which are trajectory information recorded by the first node at different times.

[0159] It should be noted that trajectory information can be used to help the second node determine the behavior of the first node. After the second node obtains the trajectory information recorded by the first node, it can record the first node's movement trajectory based on the first node's trajectory information, thereby determining the first node's behavior.

[0160] In some embodiments, the second node also needs to acquire the perception parameters recorded by the first node when it perceives unknown objects in an unknown area. Therefore, the second indication information can also be used to instruct the first node to report the perception parameters.

[0161] For example, when the second instruction information is used to instruct the first node to report the sensing parameters, the first node can also send the sensing parameters to the second node after receiving the second instruction information sent by the second node.

[0162] In some embodiments, the second node can instruct the first node to report trajectory information when it needs to obtain the trajectory information of the first node. Based on this, as... Figure 3 As shown, the above step S202 can be implemented as the following step S2021.

[0163] S2021. Upon receiving the second indication information sent by the second node, send trajectory information to the second node. The second indication information is used to indicate the reporting of trajectory information.

[0164] In some embodiments, the first node can record and report trajectory information when it determines that it has entered the sensing area based on the sensing area indication information. Therefore, step S202 can also be implemented as steps A1-A2.

[0165] A1. Once it is determined that the area has entered the sensing zone, the trajectory is recorded to obtain trajectory information.

[0166] For example, trajectory information may include location information and velocity information.

[0167] A2. Send trajectory information to the second node.

[0168] The technical solutions provided by the above embodiments bring at least the following beneficial effects: In the communication method provided by this application, after the first node receives the first instruction information sent by the second node to instruct the first node to record the trajectory within the sensing area, the first node can send trajectory information to the second node so that the second node can know the trajectory record of the first node in the sensing area. Thus, the second node can connect the target objects sensed by the first node and the second node within the sensing area without performing complex calculations, which helps the second node to further analyze the sensed target objects and improves the sensing accuracy of the communication sensing network.

[0173] For example, the first instruction information may be carried in an SIB, RMSI, or MIB.

[0174] In some embodiments, when the first node is in a connected state, the second node can send an RRC reconfiguration message to the first node.

[0185] For example, after receiving the first instruction information sent by the second node, the first node can determine the trajectory when it enters the sensing area based on the sensing area instruction information, and can also start to sense unknown objects in the sensing area based on the auxiliary sensing information.

[0186] In some embodiments, when the first indication information is carried in a system message or an RRC reconfiguration message, the specific form of the system message or RRC reconfiguration message sent by the second node to the first node can refer to the description in step S201 above, and will not be repeated here.

[0187] S302, Receive trajectory information sent by the first node.

[0188] The trajectory information includes the trajectory record of the first node in the sensing area.

[0189] In some embodiments, the second node can instruct the first node to report trajectory information when it needs to obtain the trajectory information of the first node. Based on this, as... Figure 5 As shown, the above step S302 can be implemented as the following steps S3021-S3022.

[0190] S3021. Send the second instruction information to the first node.

[0191] The second indication information is used to indicate the reporting trajectory information.

[0192] In some embodiments, the second node also needs to acquire the perception parameters recorded by the first node when it perceives unknown objects in an unknown area. Therefore, the second indication information can also be used to instruct the first node to report the perception parameters.

[0193] For example, when the second instruction information is used to instruct the first node to report the sensing parameters, the first node can also send the sensing parameters to the second node after receiving the second instruction information sent by the second node.

[0194] In some embodiments, when the first node is in a connected state, the second node can obtain the location information of the first node, confirm whether the first node is located in the sensing area based on the location information, and instruct the first node to report trajectory information if the first node is located in the sensing area. Therefore, the above step S3021 can be implemented as follows: when it is determined that the first node has entered the sensing area, send second indication information to the first node.

[0195] S3022, Receive trajectory information sent by the first node.

[0196] In some embodiments, the trajectory information sent from the first node to the second node includes position information and velocity information. The trajectory information may include multiple pieces of position and / or velocity information, which are trajectory information recorded by the first node at different times.

[0197] The technical solutions provided by the above embodiments bring at least the following beneficial effects: In another communication method provided by this application, the second node sends a first instruction information to the first node to instruct the first node to record the trajectory within the sensing area. It can also obtain the trajectory information of the first node within the sensing area, so that the second node can connect the target objects sensed by the first node and the second node within the sensing area without performing complex calculations. This helps the second node to further analyze the sensed target objects and improves the sensing accuracy of the communication sensing network.

[0198] The communication method of this application embodiment is described below with reference to a specific example, such as... Figure 6 As shown, the implementation process of this method includes the following steps S401-S403.

[0199] S401, the second node sends a first instruction message to the first node, and correspondingly, the first node receives the first instruction message sent by the second node.

[0200] The first instruction information is used to instruct the first node to record its trajectory within the sensing area.

[0201] S402, the second node sends a second instruction message to the first node, and correspondingly, the first node receives the second instruction message sent by the second node.

[0202] The second instruction information is used to instruct the first node to report trajectory information.

[0203] S403, The first node sends trajectory information to the second node, and correspondingly, the second node receives the trajectory information sent by the first node.
