[0570] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0571] Synaesthesia integration is considered to be a technology with broad application prospects. Its business service scope will break through the traditional communication dimension and can provide perception services and communication services at the same time using the same equipment. Simply put, perception services are the wireless perception capabilities of the physical world that use radio waves to achieve high-resolution perception, positioning, imaging, environmental reconstruction, posture and gesture recognition, health monitoring, material monitoring, etc. of physical objects.

[0572] The following examples illustrate the applicable scenarios of synaesthesia integration technology.

[0573] Figure 1A The figure shows a smart traffic scenario, in which vehicles and road equipment units can not only communicate but also transmit perception signals to monitor traffic conditions in real time, thereby realizing the perception of road condition information and optimizing traffic.

[0574] Figure 1B The figure shows a drone monitoring scenario, in which the synaesthesia integration technology can be used to achieve flight path planning for authorized drones and intrusion detection for unauthorized drones.

[0575] Figure 1C The figure shows a smart factory scenario, in which smart base stations, smart terminals and robots can use synesthesia integration technology to complete functions such as product detection, counting, location perception, unmanned area monitoring, gesture recognition, and environmental recognition.

[0576] Figure 1D The figure shows a respiratory monitoring scenario, in which the respiratory monitoring device can monitor the heartbeat and respiration of the human body through the synaesthesia integration technology.

[0577] Figure 1E The figure shows a gesture recognition scenario, in which the smart terminal can use the synaesthesia integration technology to realize the recognition of user gestures.

[0578] It can be seen that synaesthesia integration technology is Figure 1A Smart transportation, Figure 1B Drone monitoring, Figure 1C Smart factory shown, Figure 1D Respiratory monitoring, Figure 1E Scenarios represented by the gesture recognition shown will bring great changes to people's production and life.

[0579] In the integrated synaesthesia service, the communication capability and perception capability are not isolated, and the two empower each other to achieve a better user experience. Specifically, the integrated synaesthesia service can be divided into communication-assisted perception services and perception-assisted communication services according to the relationship between communication capability and perception capability. In the communication-assisted perception service, the reference signal in the wireless communication can be used as the perception signal to realize services such as target positioning, speed measurement, gesture recognition, etc.; the high-speed and reliable communication capability also provides guarantee for the convergence of perception data, which can further improve the perception accuracy and perception resolution. In the perception-assisted communication service, the wireless communication environment and communication nodes are detected and perceived through wireless perception technology, and various prior information such as environmental maps, communication node locations, and moving speeds can be obtained. Using the perception information and perception results, the auxiliary communication system selects algorithms, sets algorithm parameters, and optimizes algorithms for modules such as channel estimation, equalization, and beam management.

[0580] The integrated interawareness service is a service that integrates communication and perception. From the perspective of system architecture, the integration of communication and perception can be divided into the following three levels of integration: business layer integration, service layer integration, and air interface integration.

[0581] For service layer convergence, the wireless mobile communication system only serves as a data transmission channel for third-party perception services and does not provide perception services itself. Third-party perception services refer to perception services provided by systems other than the wireless mobile communication system, including services based on radar, cameras, etc.

[0582] For service layer integration, the wireless mobile communication system will form application-oriented endogenous perception services based on the perception data and communication data obtained by third-party perception units, communication units, and future inter-awareness integrated units. Third-party perception units include radars, cameras, etc. The integration of the service layer involves changes to the service layer and function layer in the wireless mobile communication system, such as the 6G system architecture.

[0583] For air interface convergence, the wireless mobile communication system will form an endogenous perception service based on the perception data obtained by the communication perception integration unit at the air interface level. The communication perception integration unit obtains perception data based on the sending and receiving of perception signals and synaesthesia integration signals. Synaesthesia integration signals are wireless signals used for both perception and communication. Air interface convergence involves changes in the functional layer and resource layer in the wireless mobile communication system, such as the 6G system architecture.

[0584] Reference model of perception services provided by synaesthesia integrated system, such as Figure 2 The perception service client can request the perception information of the perception object from the perception server, and the perception server responds to the perception request, performs the perception function, obtains the perception information of the perception object, and provides it to the perception service client.

[0585] The perception service client may be an entity outside the synaesthesia integration system, or an entity inside the synaesthesia integration system (eg, a terminal, a network function in a core network).

[0586] The perceived object and perceived information depend on different synaesthesia integration services. For example, the perceived object may be the environment, an object, a person, etc., and the perceived information may be an environment map, an image of an object, a person's speed and position, etc.

[0587] The perception server is implemented by the synaesthesia integration system, which is based on the architecture of the wireless mobile communication system and includes a core network, a wireless access network and a terminal. The perception server can determine the perception information of the perception object based on the perception data obtained by the synaesthesia integration unit and the third-party perception unit. The synaesthesia integration unit obtains the perception data by measuring the perception signals configured inside the system. The perception signals include signals dedicated to perception and signals used for both perception and communication. The technology used by the third-party perception unit to obtain the perception data is not within the scope of the synaesthesia integration system.

[0588] The process of sensing services can include:

[0589] S1: The perception service client sends a perception request to the perception server.

[0590] S2: The security and privacy protection functional entity in the perception server performs security and privacy checks.

[0591] S3: When the security and privacy check passes, the perception task management functional entity in the perception server determines the perception method, perception node, etc. If the perception data is obtained through the synaesthesia integration unit, perception resource scheduling is required, and the synaesthesia integration unit sends, receives and measures the perception signal.

[0592] S4: The perception data processing functional entity in the perception server determines the final perception information based on the perception data obtained by the synaesthesia integration unit and the third-party perception unit.

[0593] S5: The perception response returned by the perception server to the perception service client contains the final perception information.

[0594] Based on the wireless mobile communication system architecture, there are currently several considerations for the allocation of various functions to network elements.

[0595] First, the allocation of resource layer functions considers sharing equipment and devices with network elements of the resource layer of the wireless mobile communication system, thereby saving costs. The resource layer's perception signal transmission, perception signal reception and measurement, and third-party perception technology can be allocated to the wireless access network nodes and terminals that traditionally transmit and receive wireless signals.

[0596] Second, the allocation of functional layer functions is considered to be distributed in multiple network elements of the interawareness integrated system. For example, the centralized allocation of perception data processing functions requires network elements to have higher computing power support and transmission bandwidth support, while the hierarchical allocation of perception data processing functions to the core network, access network and terminal can effectively alleviate the requirements for computing power and transmission bandwidth of each network element. For another example, the perception task management function can be allocated to the core network to support perception services with a larger perception range, and can also be allocated to the access network to more efficiently support perception services that assist access network communications.

[0597] Third, whether to independently allocate each function to different network elements or to the same network element requires a comprehensive consideration of factors such as interface interaction delay and flexible organization. For example, control functions such as perception task management and perception data processing functions are allocated to different network elements to achieve control and data separation, which can support more flexible deployment. For example, the perception task management entity is deployed in the core layer, and the perception data processing entity is deployed in the edge layer, which is suitable for perception services with large bandwidth and high privacy and security requirements. Control functions such as perception task management functions and perception data processing functions are allocated in the same network element, which can avoid interface interaction between the two functions, reduce interfaces with other functions, and reduce the overall process complexity.

[0598] In the interawareness integration system, different perception modes will be formed according to the different nodes for transmitting and receiving the perception signals, and the perception modes will also affect the design of the key technologies for the interawareness integration air interface. Specific perception modes may include: base station self-transmitting and self-receiving, base station A transmitting and base station B receiving, base station transmitting and terminal receiving, terminal transmitting and base station receiving, terminal self-transmitting and self-receiving, terminal A transmitting and terminal B receiving, etc.

[0599] For example, the base station's self-transmitting and self-receiving sensing mode is as follows Figure 3A As shown, a base station sends a sensing signal, and the base station receives the sensing signal sent by itself to perform sensing.

[0600] For example, the sensing pattern of base station A sending and base station B receiving is as follows: Figure 3B As shown, base station A sends a perception signal, and base station B receives the perception signal sent by base station A to perform perception.

[0601] For example, the sensing mode of the base station sending and the terminal receiving is as follows: Figure 3C As shown, the base station sends a perception signal, and the terminal receives the perception signal sent by the base station to perform perception.

[0602] For example, the perception mode of the terminal sending and the base station receiving is as follows Figure 3D As shown, the terminal sends a perception signal, and the base station receives the perception signal sent by the terminal to perform perception.

[0603] For example, the terminal's self-transmitting and self-receiving sensing mode is as follows Figure 3E As shown, the terminal sends a perception signal, and the terminal receives the perception signal sent by itself to perform perception.

[0604] For example, the perception mode sent by terminal A and received by terminal B is as follows Figure 3F As shown, terminal A sends a perception signal, and terminal B receives the perception signal from terminal A for perception.

[0605] Below Figures 3A-3F The characteristics of the perception mode shown are described in detail.

[0606] Specifically, Figure 3A The base station shown is self-transmitting and self-receiving Figure 3E The terminal self-transmission and self-reception shown is a single-base sensing method, and the sensing is performed by one node, which is similar to the traditional single-base radar. Since the transmitter and the receiver are in the same location, the sensing signal of the single-base sensing method does not have to be a dedicated pilot signal, and the communication signal carrying data can also be used for single-base sensing. In addition, since the transmitter and the receiver share the same hardware platform, the transmitter and the receiver can easily achieve clock synchronization. Moreover, the sensing results can be directly parsed by the node without the need for additional data transmission and the assistance of external equipment. However, the single-base mode requires the base station or the terminal to have full-duplex capability. Figure 3B The situation shown in Figure 1 where base station A sends and base station B receives corresponds to one base station sending a sensing signal and the other base station receiving the sensing signal for sensing. This method is similar to the working mode of a traditional bistatic radar. Due to the spatial separation of the transmitter and the receiver, this mode does not require the transceiver to have full-duplex capability, and the clock synchronization of the transmitter and the receiver is also easier to achieve. However, this mode requires a dedicated sensing signal, and the position error and synchronization error of the transmitter and the receiver will also affect the sensing result. Figure 3C The base station sends and receives Figure 3D The terminal transmitting and base receiving shown is another form of dual-base working mode, where one of the transmitter and the receiver is the base station and the other is the terminal. Figure 3C The base station sends and receives Figure 3D The terminal transmitter and base station receiver shown in the figure can also use the communication signal carrying data for perception, but the communication data needs to be decoded before perception processing. If the communication data is decoded incorrectly (for example, in a working environment with a very low signal-to-noise ratio), the perception performance will deteriorate. In addition, Figure 3C The base station sends and receives Figure 3D The clock synchronization of the transceivers sent by the terminal and received by the base station is also a challenge. Figure 3F The terminal A sends and the terminal B receives also have Figure 3C The base station sends and receives Figure 3D The characteristics of the terminal sending and base station receiving are shown. Figure 3E The terminal shown is self-transmitting and self-receiving Figure 3F The sensing function of the terminal A sending and the terminal B receiving is relatively independent of the wireless communication network, and can even sense outside the coverage of the wireless communication network. Figure 3E The terminal shown is self-transmitting and self-receiving Figure 3F In the example shown, terminal A sends and terminal B receives. Due to the limitation of terminal transmission power, the sensing range is smaller than other methods. In addition, the position error caused by the mobility of the terminal will affect the sensing result.

[0607] Furthermore, control functions such as perception task management and perception data processing functions can be flexibly allocated to core network devices, access network devices, and / or terminals. For example, for typical scenarios such as environmental map maintenance and navigation obstacle avoidance, the core network device can control the access network device (such as a base station) and the terminal to perform perception services and report perception results, or the access network device can control the execution of the perception service.

[0608] In order to ensure the continuity of data services, the inter-sensing integrated system can introduce mobility management. When the terminal needs to perform continuous sensing services, it is also necessary to consider ensuring the continuity of sensing services. For example, the sensed object may move from one cell to another, or the sensing terminal itself may move, which can lead to sensing interruption and inability to continuously monitor the target object. If the sensing is interrupted, the direct consequence is the loss of monitoring of the target object and various potential safety hazards.

[0609] In one embodiment, when the terminal performs a sensing service for detection and tracking, if the terminal moves from one cell to another cell, after the cell switching of the terminal is completed, the sensing process of the terminal may be scheduled by the new resident cell.

[0610] See also Figure 4A As shown in the figure, when the terminal performs the perception service before the cell switching and detects an abnormal environment or performs tracking, it is necessary to start the perception in the new cell after the switching as soon as possible to achieve continuous and uninterrupted detection or tracking. However, the terminal needs to be instructed by the network to perform the perception service in the new cell. The signaling process of the network triggering the perception behavior has a large delay, such as the base station sending the configuration of the perception parameters, the base station triggering the perception, the terminal detecting the perception signal sent by the base station, or the terminal sending the perception signal to the network, etc., which cannot guarantee the timeliness and accuracy of the perception service, and may even cause the detection or tracking to be interrupted.

[0611] In view of this, the embodiments of the present application also provide another perception method, device and equipment, which can improve the accuracy and timeliness of the communication and perception integrated system's environmental perception.

[0612] The system architecture applicable to the perception method of the embodiment of the present application is as follows: Figure 4BAs shown, it includes: a core network, an access network and a terminal. The core network may include: a core network server, and the access network may include: an access network device, wherein the access network device may include: a base station, a transmission and reception point (TRP), etc. The core network server and the access network device may be collectively referred to as a network side device.

[0613] The terminal in the embodiments of the present application can be, for example, user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, etc.

[0614] In a sensing method provided in an embodiment of the present application, cell-related information including information of the second cell is associated with sensing, so that after receiving the cell-related information including information of the second cell, the terminal can sense the second cell in a timely manner. Figures 5A to 12F An exemplary description is given.

[0615] Figure 5A In the embodiment of the present application shown, when the cell-related information received by the first cell includes information about the second cell, the terminal senses the second cell.

[0616] Figure 5A The method shown can be executed by a terminal. Figure 5A As shown, the method may include:

[0617] Step 501: Receive cell-related information in a first cell.

[0618] Step 502: If the cell-related information includes information of the second cell, sense the second cell.

[0619] The cell-related information is used to indicate the cell. The cell-related information may include, but is not limited to: information about the cell, such as an identifier or index of the cell; information associated with the cell, such as parameter information of the airspace, frequency domain, and time domain used for the transmission channel between the network and the terminal in the cell. In some embodiments, the cell-related information may also be referred to as cell information.

[0620] Optionally, the first cell and the second cell may be sensing cells in the sensing service. The second cell may be a cell other than the first cell, such as a neighboring cell.

[0621] Optionally, if the division method of the perception cells in the perception service is the same as the division method of the cellular cells in the communication service, in other words, the service coverage of the cellular cells and the perception cells is the same, then the above-mentioned first cell and second cell may also be the cellular cells in the communication service.

[0622] Optionally, the cell-related information including the information of the second cell can be used for cell update or cell-related information update, such as beam update, TCI status update, cell switching, or cell activation. In cell switching, the first cell can be the cell where the terminal resides before switching, and the second cell can be the target cell of the terminal switching, that is, the cell where the terminal resides after switching; in cell activation, the first cell can be the cell where the terminal resides, and the second cell can be the target cell to be activated. After receiving the cell-related information in the first cell, the terminal can perform cell update or cell-related information update based on the cell-related information, such as the above-mentioned beam update, TCI status update, cell switching, or cell activation. The step of sensing the second cell in step 502 and the step of the terminal performing cell update based on the cell-related information can be performed in parallel or in series. When the two steps are performed in series, the execution order of the steps is not limited. In other words, the step of sensing the second cell in step 502 can be performed before the step of the terminal performing cell information update based on the cell-related information, or it can be performed after the step of the terminal performing cell information update based on the cell-related information.

[0623] Based on this, when the terminal senses the second cell, it can cooperate with the network side device of the first cell (hereinafter referred to as network side device 1) to sense the second cell, or it can also cooperate with the network side device of the second cell (hereinafter referred to as network side device 2) to sense the second cell. For example, in a cell switching scenario, when the terminal has not switched to the second cell, the terminal can cooperate with the network side device 1 to sense the second cell, and after the terminal switches to the second cell, the terminal can cooperate with the network side device 2 to sense the second cell.

[0624] Optionally, the network side device 1 and the network side device 2 may be access network devices such as base stations respectively.

[0625] Optionally, when the terminal senses the second cell in step 502, it may sense the second cell according to the perception-related information. The above-mentioned perception-related information may be predefined in the terminal according to the protocol, or sent to the terminal by the network-side device independently of the cell-related information (hereinafter also referred to as network configuration), or may be associated with the cell-related information. When the perception-related information includes multiple pieces of information, two or more of the above-mentioned methods of predefinition in the terminal according to the protocol, network configuration, association with cell-related information, etc. may also be combined, as long as the terminal can obtain the perception-related information for perception. For example, some items of information in the perception-related information may be predefined in the terminal according to the protocol, and some items of information may be associated with cell-related information.

[0626] Optionally, when the network side device sends perception related information to the terminal independently of the cell related information, the above network side device may specifically be a core network server, network side device 1, or network side device 2, that is, the core network server, network side device 1, or network side device 2 may send the perception related information to the terminal, which may be specifically related to the implementation scenario. For example, in a cell switching scenario, if the terminal cooperates with the network side device 1 to perceive the second cell before the terminal switches to the second cell, then the network side device 1 may send the perception related information to the terminal, and if the terminal cooperates with the network side device 2 to perceive the second cell after the terminal switches to the second cell, then the network side device 1 may send the perception related information to the terminal before switching to the second cell, and the network side device 2 may send the perception related information to the terminal after switching to the second cell.

[0627] Optionally, associating the above-mentioned cell-related information with the perception-related information may specifically include: the cell-related information includes the perception-related information, or there is a corresponding relationship between the cell-related information and the perception-related information.

[0628] When the above-mentioned cell-related information includes perception-related information, for example, a field may be added to the existing cell-related information to indicate the perception-related information, or a field in the existing cell-related information may be used to indicate the perception-related information.

[0629] When there is a corresponding relationship between the cell-related information and the perception-related information, the cell-related information may not include the perception-related information, but the cell-related information has corresponding perception-related information, so that the perception-related information can also be determined according to the cell-related information.

[0630] The implementation of including the information of the second cell in the cell-related information and the implementation of associating the cell-related information with the perception-related information are exemplarily described through the following examples 1 to 5.

[0631] Example 1: The cell-related information may be a transmission configuration indication state (TCI state), and the information of the second cell may be an identifier (ID) or index (index) of the second cell contained or associated with the TCI state. At this time, if the TCI state received by the terminal in the first cell includes or associates the identifier or index of the second cell, the terminal may determine that the cell-related information includes the information of the second cell.

[0632] For example Figure 5B The portion marked by a black box shows that the value of the parameter additional physical cell identifier (PCI) in the TCI state may be the identifier of the second cell.

[0633] It should be noted that the second cell may specifically be a cell, a serving cell or a physical cell, and the identifier or index of the second cell may specifically be an identifier or index of a cell, a serving cell or a physical cell.

[0634] Optionally, the TCI state including the identifier or index of the second cell in this embodiment may be the TCI state used when the terminal and the network side device 2 perform channel or signal transmission.

[0635] In this example, if the cell-related information is associated with the perception-related information, it can specifically be the TCI state associated with the perception-related information, or the quasi-co-site source reference signal (QCL source RS) included in the TCI state associated with the perception-related information.

[0636] Optionally, the TCI state-associated perception-related information may specifically be that the TCI state includes the perception-related information, or the TCI state has a corresponding relationship with the perception-related information.

[0637] Optionally, the associating the quasi co-located source reference signal with the perception related information may specifically be that the quasi co-located source reference signal and the perception related information have a corresponding relationship.

[0638] Taking the implementation of cell-related information through TCI state as an example, the correspondence between TCI state or quasi-co-location source reference signal and perception-related information is shown in Table 1 below.

[0639]

[0640]

[0641] Table 1

[0642] It should be noted that the network side device may set some TCI states or some quasi-co-located source reference signals to have an association relationship with the perception-related information, or may set all TCI states or all quasi-co-located source reference signals to have an association relationship with the perception-related information. Referring to Table 1, multiple TCI states or multiple quasi-co-located source reference signals may be associated with the same perception signal, and multiple TCI states or multiple quasi-co-located source reference signals may be associated with the same perception report.

[0643] Optionally, based on the above example 1, the receiving of cell related information in step 501 may be implemented in the following manner:

[0644] receiving beam configuration information, where the beam configuration information includes cell-related information; or,

[0645] receiving a beam activation command, where the beam activation command includes cell-related information; or,

[0646] Receive downlink control information, where the downlink control information includes cell-related information.

[0647] For example, in the beam update behavior, the network side device such as the base station can configure the TCI state pool (pool) through the radio resource control (RRC) signaling, and then activate one or more TCI states through the media access control (MAC) control element (CE) signaling. When multiple TCI states are activated, downlink control information (DCI) can be used to indicate at least one activated TCI state. The above-mentioned beam configuration information can be, for example, the RRC signaling for configuring the TCI state pool, and the cell-related information can be at least one TCI state in the TCI state pool configured by the RRC signaling. The above-mentioned beam activation command can be, for example, the MAC CE signaling for activating the TCI state, and the cell-related information can be at least one TCI state in the TCI state activated by the MAC CE signaling. The above-mentioned downlink control information can be, for example, the DCI indicating the TCI state, and the cell-related information can be at least one TCI state in the TCI state indicated by the DCI.

[0648] It should be noted that, in some instances, the information related to the beam may include: one or more of the following: beam identification information, spatial relation information, spatial domain transmission filter information, spatial domain reception filter information, spatial domain filter information, transmission configuration indication state (TCI state) information, quasi co-location (QCL) information, QCL parameters, etc. Among them, the relevant information of the downlink beam can usually be represented by TCI state information or QCL information. The relevant information of the uplink beam can usually be represented by TCI state information or spatial relation information.

[0649] Example 2: The cell-related information may be a TCI state, and the information of the second cell may be a quasi-co-site source reference signal in the TCI state, where the quasi-co-site source reference signal is a reference signal (RS) of the second cell. At this time, if the quasi-co-site source reference signal in the TCI state received by the terminal in the first cell is a reference signal of the second cell, the terminal can determine that the cell-related information includes information of the second cell.

[0650] In this example, if the cell-related information is associated with the perception-related information, it may specifically be the TCI state associated with the perception-related information, or the quasi-co-site source reference signal included in the TCI state associated with the perception-related information.

[0651] Example three: The cell-related information may be a beam update response, and the information of the second cell may be a reference signal indicating the new beam in the beam update response, and the reference signal is the reference signal of the second cell. At this time, if the reference signal indicating the new beam in the beam update response received by the terminal in the first cell is the reference signal of the second cell, the terminal can determine that the cell-related information includes the information of the second cell.

[0652] Alternatively, the cell-related information may be a beam update response, and the information of the second cell may be an identifier or index of the second cell associated with the beam update response. At this time, if the beam update response received by the terminal in the first cell is associated with the identifier or index of the second cell, the terminal can determine that the cell-related information includes the information of the second cell.

[0653] The beam update request and the beam update response are information used in beam updating. The beam update request may be, for example, a beam failure recovery request (BFRQ), and the beam update response may be, for example, a beam failure recovery response (BFRR).

[0654] BFRR is the response information sent by the access network device or core network server to the terminal after receiving the BFRQ of the terminal. BFRR is usually carried by the physical downlink control channel (PDCCH). The new beam information takes effect after a preset time after BFRR. BFRQ is the information sent by the terminal to the network side device when the terminal finds a beam failure event through measurement. BFRQ is usually carried on MAC CE or physical random access channel (PRACH).

[0655] In this example, if the cell-related information is associated with the perception-related information, it may be that the beam update response is associated with the perception-related information, or the reference signal indicating the new beam in the beam update response is associated with the perception-related information.

[0656] Optionally, the beam update response associated with the perception related information may specifically be that the beam update response includes the perception related information, or has a corresponding relationship with the perception related information.

[0657] Optionally, the association of the reference signal indicating the new beam in the beam update response with the perception-related information may specifically mean that the reference signal indicating the new beam has a corresponding relationship with the perception-related information.

[0658] Optionally, when the cell-related information is a beam update response, the step before step 501 may also include: sending a beam update request.

[0659] Optionally, the beam update request may be associated with perception request information, where the perception request information is used to request perception.

[0660] Example 4: The cell-related information may be a cell switching command, and the information of the second cell may be an identifier or index of the target cell in the cell switching command. At this time, if the cell switching command received by the terminal in the first cell includes the identifier or index of the target cell, the terminal may determine that the cell-related information includes the information of the second cell.

[0661] Optionally, when the cell-related information is a cell switching command, the process before step 501 may further include: sending a cell switching request.

[0662] Optionally, the cell switching request may be associated with perception request information, where the perception request information is used to request perception.

[0663] In this example, if the cell-related information is associated with the perception-related information, it may be specifically that the cell switching command is associated with the perception-related information. Optionally, the cell switching command is associated with the perception-related information and specifically may be: the cell switching command includes the perception-related information. Optionally, the cell switching command may include the TCI state, and the cell switching command is associated with the perception-related information and specifically may be: the TCI state in the cell switching command is associated with the perception-related information, for example, the TCI state may have a corresponding relationship with the perception-related information.

[0664] Optionally, the cell switching command may be MACCE signaling for cell switching introduced in 3GPP Release 18.

[0665] Cell switching process see Figure 5C As shown, it includes processes such as UE reconfiguration (UE reconfiguration), downlink synchronization (DL synchronization), and uplink synchronization (UL synchronization).

[0666] Example 5: The cell-related information may be a cell activation command, and the information of the second cell may be the identifier or index of the target cell to be activated in the cell activation command. At this time, if the cell activation command received by the terminal in the first cell includes the identifier or index of the cell to be activated, the terminal can determine that the cell-related information includes the information of the second cell.

[0667] Optionally, when the cell-related information is a cell activation command, the process before step 501 may further include: sending a cell activation request.

[0668] Optionally, the cell activation request may be associated with perception request information, where the perception request information is used to request perception.

[0669] In this example, if the cell related information is associated with the perception related information, it may be that the cell activation command is associated with the perception related information. Optionally, the cell activation command is associated with the perception related information. Optionally, the cell activation command may include the perception related information. Optionally, the cell activation command may include the reference signal of the target cell to be activated, for example Figure 5D The TRS in the cell activation command shown, the cell activation command associated perception related information can specifically be: the reference signal of the target cell to be activated is associated with the perception related information, for example, the reference signal of the target cell to be activated can have a corresponding relationship with the perception related information.

[0670] Optionally, the cell activation command may be MACCE signaling for cell activation introduced in 3GPP Release 17.

[0671] The following is an exemplary description of the implementation of perception-related information.

[0672] Optionally, when the cell-related information is associated with the perception-related information, the perception-related information associated with the cell-related information may indicate at least one of the following:

[0673] Perception association status, perception trigger indication, perception mode, perception signal set, perception signal resources, perception signal configuration, perception report configuration.

[0674] Optionally, when the terminal predefines the perception-related information according to the protocol, or the network-side device sends the perception-related information to the terminal independently of the cell-related information, the perception-related information may indicate at least one of the following:

[0675] Perception mode, perception signal set, perception signal resources, perception signal configuration, perception report configuration.

[0676] The perception association state indicates the situation where the cell-related information is associated with the perception-related information. For example, there may be 1 bit of information in the cell-related information to indicate the perception association state. When the 1 bit of information is 0, it indicates that the cell-related information is not associated with the perception-related information, and when the 1 bit of information is 1, it indicates that the cell-related information is associated with the perception-related information. Alternatively, when the 1 bit of information is a specific value (such as 1), it indicates that the cell-related information is associated with the perception-related information; when the 1 bit of information is empty, or there is no 1 bit of information in the cell-related information, it indicates that the cell-related information is not associated with the perception-related information.

[0677] The perception trigger indication is used to trigger the terminal to perform perception. In other embodiments, the perception trigger indication may also be sent independently of the perception related information.

[0678] Perception patterns may include, but are not limited to:

[0679] Perception mode 1: the network side device 2 sends a perception signal, the terminal measures and sends a perception report to the network side device 2;

[0680] Perception mode 2: Network side device 2 sends a perception signal, and the terminal measures and sends a perception report to network side device 1;

[0681] Perception mode 3: Network side device 2 sends a perception signal, and the terminal measures and sends a perception report to network side device 1 and network side device 2;

[0682] Perception mode 4: The terminal sends a perception signal, and the network-side device 2 measures and obtains the perception result;

[0683] Perception mode 5: the terminal sends a perception signal, the network side device 2 measures and obtains the perception result and sends the perception result to the network side device 1.

[0684] Optionally, in other embodiments, the perception mode may further include:

[0685] Perception mode 6: Network side device 1 sends a perception signal, and the terminal measures and sends a perception report to the network side device 1;

[0686] Perception mode 7: Network side device 1 sends a perception signal, the terminal measures and sends a perception report to network side device 2;

[0687] Perception mode 8: Network side device 1 sends a perception signal, and the terminal measures and sends a perception report to network side device 1 and network side device 2;

[0688] Perception mode 9: The terminal sends a perception signal, and the network side device 1 and the network side device 2 respectively measure and obtain the perception results.

[0689] It should be noted that the above perception modes are only examples and are not intended to limit the implementation of the perception modes.

[0690] The perception signal is a signal used to detect and obtain environmental information. The perception signal is received, detected and analyzed at the receiving end. The perception signal can be a signal dedicated to the perception service, which can be multiplexed with the communication signal in multiple dimensions (for example, time domain, frequency domain, spatial domain, code domain, etc.) and have a corresponding resource configuration method. The perception signal can also be a reference signal in the communication signal, such as: SSB, CSI-RS, SRS, and a reference signal for positioning.

[0691] Optionally, the perception-related information may carry information indicating the perception mode, such as a perception mode identifier, to indicate a specific perception mode.

[0692] Optionally, the perception-related information may carry perception signal indication information to indicate a perception signal set, a perception signal resource, and / or a configuration of a perception signal. For example, the perception signal indication information may specifically include a perception signal identifier, a perception signal set identifier, a perception signal configuration identifier, and / or a perception signal resource identifier, etc.

[0693] Optionally, the perception-related information may carry configuration information of the perception report, or may carry an identifier of the perception report, and the identifier of the perception report is associated with the configuration information of the perception report.

[0694] For example:

[0695] The perception association status can be used to indicate to the terminal that the cell-related information subsequently sent by the network side device is associated with the perception-related information. At this time, the perception-related information associated with the cell-related information in this step can only indicate the perception association status, so that the terminal can know based on the perception association status that the subsequent cell-related information is associated with the perception-related information. At this time, the perception-related information associated with the cell-related information subsequently sent by the network side device to the terminal can indicate at least one of the perception trigger indication, the perception mode, the perception signal set, the perception signal resource, the configuration of the perception signal, and the configuration of the perception report.

[0696] Alternatively, the perception association status is used to indicate whether the relevant information of the cell to which the terminal belongs is associated with the perception related information. When the perception association status indicates that the relevant information of the cell to which the terminal belongs is associated with the perception related information, the terminal can further learn the perception related information associated with the cell related information. The associated perception related information can be pre-configured by the network side device, or indicated by the network side device in the cell related information. At this time, the perception related information can also indicate at least one of the perception mode, the perception signal set, the perception signal resource, the configuration of the perception signal, the configuration of the perception report, and the perception trigger indication.

[0697] Alternatively, if the terminal has already learned in advance through network configuration or protocol pre-definition that there is only one set of perception configurations (including: one perception mode, one perception signal set, and one perception report configuration), the perception-related information associated with the cell-related information may also only indicate the perception association state, without indicating at least one of the perception mode, perception signal set, perception signal resource, perception signal configuration, perception report configuration, and perception trigger indication.

[0698] When the perception-related information associated with the cell-related information indicates at least one of the perception mode, the perception signal set, the perception signal resource, the configuration of the perception signal, and the configuration of the perception report, if the cell-related information also includes a perception trigger indication, the terminal may perform perception according to the perception trigger indication using information such as the perception mode, the perception signal, or the perception report, or the network side device may send a perception trigger indication to the terminal before or after indicating the cell-related information, and the terminal may perform perception according to the perception trigger indication using information such as the perception mode, the perception signal, or the perception report indicated by the perception-related information associated with the cell-related information.

[0699] If the terminal has already known the sensing mode, sensing signal set, sensing signal resource, sensing signal configuration, sensing report configuration and other information in advance through network configuration or protocol pre-definition, and the network side device hopes that the terminal will sense after receiving the cell related information, the sensing related information associated with the cell related information may only indicate the sensing trigger indication. If the terminal has already known the sensing mode in advance through network configuration or protocol pre-definition, and the network side device hopes that the terminal will sense after receiving the cell related information, the sensing related information associated with the cell related information may indicate at least one of the sensing trigger indication, sensing signal set, sensing signal resource, sensing signal configuration and sensing report configuration. Similarly, if the terminal has already known the sensing mode and sensing signal set in advance through network configuration or protocol pre-definition, and the network side device hopes that the terminal will sense after receiving the cell related information, the sensing related information associated with the cell related information may indicate at least one of the sensing trigger indication and sensing report configuration. Other similar implementations are not listed one by one.

[0700] If the terminal senses the second cell after receiving cell-related information including information about the second cell through network configuration or protocol predefinition, the perception-related information associated with the cell-related information may not indicate a perception trigger indication, but only indicates at least one of the perception association state, perception mode, perception signal set, perception signal resources, perception signal configuration, and perception report configuration.

[0701] Optionally, when the network side device sends a perception trigger indication to the terminal independently of perception-related information, if the terminal cooperates with the network side device 1 to perceive the second cell when the terminal has not switched to the second cell, then the network side device 1 can send the perception trigger indication to the terminal; if the terminal cooperates with the network side device 2 to perceive the second cell after the terminal switches to the second cell, then the network side device 1 can send the perception trigger indication to the terminal before switching to the second cell, and the network side device 2 can also send the perception trigger indication to the terminal after switching to the second cell.

[0702] The following is an exemplary description of a possible implementation manner in which the terminal senses the second cell in step 502.

[0703] In the first embodiment, sensing the second cell in step 502 may be implemented in the following manner:

[0704] After receiving the cell-related information, after a time interval t1, the second cell is sensed.

[0705] Optionally, the time interval t1 may be configured for the terminal by the network side device, or may be pre-agreed upon by a protocol, or may be determined in real time by the terminal based on a preset algorithm or policy.

[0706] Optionally, when the above-mentioned time interval t1 is configured for the terminal by a network side device (for example, a core network server, network side device 1, or network side device 2), the following steps may also be included before step 502: receiving configuration information of the time interval t1, and the configuration information of the time interval t1 is used to indicate the length of the above-mentioned time interval t1.

[0707] Optionally, the start time of the time interval t1 may be: the time when the cell-related information takes effect, the time when the cell-related information is received, or the time when a confirmation message of the cell-related information is sent.

[0708] Optionally, when the cell-related information is a beam update response, the start time of the time interval t1 may be the time when the beam update request is sent, or the start time of the time interval may be the time when the beam update is completed.

[0709] Optionally, when the cell-related information is in TCI state, the start time of the time interval t1 may also be: the time when the TCI state switching is completed.

[0710] Optionally, when the cell-related information is a cell switching command, the start time of the time interval t1 may also be: the time when the cell switching is completed.

[0711] Optionally, when the cell-related information is a cell activation command, the start time of the time interval t1 may also be: the time when the cell activation is completed.

[0712] In the second embodiment, sensing the second cell in step 502 may be implemented in the following manner:

[0713] After receiving the cell-related information, the second cell is sensed within the time window a1.

[0714] Optionally, the time window a1 may be configured for the terminal by a network-side device, or may be pre-agreed upon by a protocol, or may be determined in real time by the terminal based on a preset algorithm or strategy.

[0715] Optionally, the time window a1 can be determined by at least two of the starting position of the time window a1, the length of the time window a1, and the ending position of the time window a1. At this time, the at least two pieces of information used to determine the time window a1 can be partially configured by the network side device for the terminal, and partially determined by the terminal based on a protocol agreement, a preset algorithm, or a preset strategy.

[0716] Optionally, the network side device may configure the information of the time window a1 for the terminal so that the terminal can determine the time window a1, and the following steps may be further included before step 502:

[0717] Configuration information of the time window a1 is received, where the configuration information of the time window a1 is used to indicate the time window a1.

[0718] Optionally, the configuration information of the time window a1 includes at least one of the following: the starting position of the time window a1, the length of the time window a1, and the ending position of the time window a1. When the configuration information of the time window a1 includes one of the starting position of the time window a1, the length of the time window a1, and the ending position of the time window a1, other information used to determine the time window a1 may be determined by the terminal based on a protocol agreement, a preset algorithm, or a preset policy. For example, if the configuration information of the time window a1 includes: the starting position of the time window a1, the length and / or ending position of the time window a1 may be determined by the terminal based on a protocol agreement, a preset algorithm, or a preset policy.

[0719] It should be noted that the time window a1 may not be periodic but one-time (one shop).

[0720] In a third embodiment, the above two embodiments may be combined. In this case, sensing the second cell in step 502 may be implemented in the following manner:

[0721] After receiving the cell related information, after a time interval t1, sensing is performed according to the sensing related information within the time window a1.

[0722] The method for determining the time interval t1 and the method for determining the time window a1 in this example can refer to the above examples and will not be described in detail here.

[0723] In a fourth embodiment, the time interval, time window, etc. in the above embodiments may also be carried by a perception trigger indication, and the above embodiments may determine the above time interval, time window, etc. according to the time information included in the perception trigger indication, and then perform perception. Based on the above description, the perception trigger indication may be carried by the perception related information associated with the cell related information, or may not be carried in the perception related information, but the network side device may send the perception trigger indication to the terminal before or after sending the cell related information.

[0724] In the fifth embodiment, the perception trigger indication may also carry other time information to indicate the time for perception to the terminal. Accordingly, in this step, perception may also be performed according to the time information carried by the perception trigger indication and the perception related information.

[0725] In the sixth example, the step of determining the start time of perception may be included before step 502 .

[0726] The starting time of perception can be determined in the following ways:

[0727] Determine the sensing start time according to the effective time of the cell-related information; or,

[0728] Determine the sensing start time according to the reception time of the cell related information; or,

[0729] Determine the sensing start time according to the sending time of the confirmation message of the cell related information; or,

[0730] When the cell-related information is a beam update response, the sensing start time is determined according to the sending time of the beam update request; or,

[0731] When the cell-related information is a beam update response, the sensing start time is determined according to the beam update completion time; or,

[0732] When the cell-related information is in TCI state, the sensing start time is determined according to the time when the TCI state switching is completed; or,

[0733] When the cell-related information is a cell switching command, the sensing start time is determined according to the time when the cell switching is completed; or,

[0734] When the cell-related information is a cell activation command, the sensing start time is determined according to the time when the cell activation is completed.

[0735] In another embodiment provided in the present application, Figure 5A The method shown may also include the following steps:

[0736] A perception enabling indication information is received, where the perception enabling indication information indicates that cell-related information including information of a second cell is used to trigger perception.

[0737] Optionally, this step may be performed before step 501 .

[0738] By executing this step, the network side device can determine whether the cell-related information is used to trigger perception according to actual needs, and send the above-mentioned perception enable indication information to the terminal when the cell-related information is needed to trigger perception, thereby making the perception triggering method more flexible.

[0739] Figure 5A In the method shown, when the cell-related information received by the first cell includes information of the second cell, the second cell is perceived, thereby associating the cell update behavior with the perception behavior. By utilizing the association relationship, the perception behavior can be initiated when the cell update behavior occurs, without the need for additional transmission of the signaling required for the perception behavior. Communication-assisted perception is realized in the interawareness integrated system, the perception process is accelerated, the signaling overhead and delay of the perception process are reduced, the terminal surrounding environment information is obtained in a timely manner, the environmental map on the network side is updated, and the communication performance is improved.

[0740] Figure 6 In the illustrated embodiment of the present application, when the network side device 1 sends cell-related information including information of the second cell to the terminal in the first cell, the terminal can perceive the second cell.

[0741] Figure 6 The method shown can be executed by the network side device 1. Figure 6 As shown, the method may include:

[0742] Step 601: Send cell-related information in a first cell, where the cell-related information includes information of a second cell.

[0743] Optionally, the cell-related information including the information of the second cell in this step may be used to trigger the terminal to perceive the second cell.

[0744] The cell related information in this step may be associated with the sensing related information, or may not be associated with the sensing related information.

[0745] The implementation of this step can refer to Figure 5A The main difference between the corresponding descriptions in is that Figure 5AIn the example, the terminal receives the cell related information in the first cell, while in this step, the network side device 1 sends the cell related information in the first cell.

[0746] In the first embodiment, when the cell-related information is a beam update response, the step before step 601 may also include: receiving a beam update request.

[0747] Optionally, the beam update request may be associated with perception request information, where the perception request information is used to request perception.

[0748] In the second embodiment, when the cell-related information is a cell switching command, the step before step 601 may further include: receiving a cell switching request.

[0749] Optionally, the cell switching request may be associated with perception request information, where the perception request information is used to request perception.

[0750] In the third embodiment, when the cell-related information is a cell activation command, the step before step 601 may further include: receiving a cell activation request.

[0751] Optionally, the cell activation request may be associated with perception request information, where the perception request information is used to request perception.

[0752] Optionally, the above-mentioned perception request information may indicate at least one of the following: a perception association state, a perception mode, a perception signal set, a perception signal resource, a perception signal configuration, and a perception report configuration.

[0753] It should be noted that when the cell-related information in step 601 is associated with the perception-related information, the information indicated by the perception request information and the perception-related information associated with the cell-related information in step 601 may be the same or different, and the embodiment of the present application does not limit this. Taking the beam update request as BFRQ and the beam update response as BFRR as an example, the role of the BFRQ-associated perception request information is to request the network-side device 1 to perform perception according to the perception request information, but the perception-related information actually indicated by the network-side device 1 for the terminal is not necessarily the information requested by the terminal, that is, it is not necessarily the information indicated by the perception request information. The terminal can specifically perform perception according to the perception-related information associated with the BFRR.

[0754] Here are some examples:

[0755] Example 1: The sensing related information and the sensing request information may indicate information of different items in the sensing association state, sensing mode, sensing signal set, sensing signal resource, sensing signal configuration, and sensing report configuration. For example, the sensing related information associated with the cell related information in step 601 indicates the sensing signal set, and the sensing request information indicates the sensing mode.

[0756] Example 2: Perception-related information and perception request information may indicate information of the same items in the above-mentioned perception association status, perception mode, perception signal set, perception signal resources, perception signal configuration, and perception report configuration. For example, the perception-related information associated with the cell-related information in step 601 indicates the perception mode, and the perception request information also indicates the perception mode. At this time, the perception mode indicated by the perception-related information may be the same as or different from the perception mode indicated in the perception request information. However, when the terminal perceives the second cell in subsequent steps, it perceives the second cell based on the perception mode indicated in the perception-related information.

[0757] When the terminal does not switch from the first cell to the second cell, the network side device 1 may cooperate with the terminal to sense the second cell. At this time, step 601 may further include: sensing the second cell.

[0758] Optionally, when the network side device 1 senses the second cell, it may sense it according to the perception related information. If the network side device 1 indicates the perception related information for the terminal to sense the second cell, for example, the network side device 1 sends the perception related information to the terminal, or the cell related information sent by the network side device 1 to the terminal is associated with the perception related information, then the network side device 1 may sense the second cell according to the perception related information indicated for the terminal.

[0759] Alternatively, if the network side device 1 does not indicate to the terminal the perception-related information for use in perceiving the second cell, the network side device 1 may perceive the second cell according to the perception-related information predefined by the protocol or configured for the network side device 1 by the core network server.

[0760] It should be noted that when the perception-related information includes multiple pieces of information, the above-mentioned methods can also be combined, as long as the network-side device and the terminal can cooperate to complete the perception of the second cell. For example, the perception-related information based on which the network-side device 1 perceives the second cell may include some items of information that can be predefined in the network-side device 1 according to the protocol, and some items of information may be associated with the cell-related information or configured by the core network server.

[0761] The following is an exemplary description of the implementation of the network side device 1 sensing the second cell.

[0762] In the first embodiment, the network side device 1 may sense the second cell in the following manner:

[0763] After the first cell sends the cell-related information, after a time interval t2, the second cell is sensed.

[0764] Optionally, the time interval t2 may be configured by the core network server for the network side device 1, or may be pre-agreed upon by a protocol, or may be determined in real time by the network side device 1 based on a preset algorithm or policy.

[0765] Optionally, when the time interval t2 is configured by the core network server for the network side device 1, the network side device 1 may also include the following steps before sensing the second cell: receiving configuration information of the time interval t2, and the configuration information of the time interval t2 is used to indicate the length of the time interval t2.

[0766] Optionally, the network side device 1 can configure the time interval t2 to the terminal. At this time, the network side device 1 can also include the following steps before sensing the second cell: sending configuration information of the time interval t2, and the configuration information of the time interval t2 is used to indicate the length of the time interval t2.

[0767] Optionally, the start time of the time interval t2 may be: the time when the cell-related information takes effect, the time when the cell-related information is sent, or the time when a confirmation message of the cell-related information is received.

[0768] Optionally, when the cell-related information is a beam update response, the starting time of the time interval t2 may be the time when the beam update request is received, or the starting time of the time interval t2 may be the time when the beam update is completed.

[0769] Optionally, when the cell-related information is in TCI state, the starting time of the time interval t2 may also be: the time when the TCI state switching is completed.

[0770] Optionally, when the cell-related information is a cell switching command, the start time of the time interval t2 may also be: the time when the cell switching is completed.

[0771] Optionally, when the cell-related information is a cell activation command, the start time of the time interval t2 may also be: the time when the cell activation is completed.

[0772] In the second embodiment, the network side device 1 can sense the cell in the following ways:

[0773] After the first cell sends the cell-related information, the second cell is sensed within the time window a2.

[0774] Optionally, time window a2 can be configured by the core network server for the network side device 1, or can be pre-agreed by a protocol, or can be determined in real time by the network side device 1 based on a preset algorithm or strategy, or can be determined by a combination of at least two of the above three methods.

[0775] For example, the time window a2 can be determined by at least two of the starting position of the time window a2, the length of the time window a2, and the ending position of the time window a2. At this time, the at least two pieces of information used to determine the time window a2 can be partially configured by the core network server for the network side device 1, and partially determined by the network side device 1 based on a protocol agreement, a preset algorithm, or a preset strategy.

[0776] Optionally, the core network server may configure the information of the time window a2 for the network side device 1 so that the network side device 1 determines the time window a2. The network side device 1 may further include the following steps before sensing the second cell:

[0777] Configuration information of the time window a2 is received, where the configuration information of the time window a2 is used to indicate the time window a2.

[0778] Optionally, the network side device 1 can configure the information of the time window a2 to the terminal. At this time, the network side device 1 can also include the following steps before sensing the second cell: sending the configuration information of the time window a2, and the configuration information of the time window a2 is used to indicate the above-mentioned time window a2.

[0779] Optionally, the configuration information of the time window a2 includes at least one of the following: the starting position of the time window a2, the length of the time window a2, and the ending position of the time window a2. When the configuration information of the time window a2 includes one of the starting position of the time window a2, the length of the time window a2, and the ending position of the time window a2, other information used to determine the time window a2 can be determined by the network side device 1 based on a protocol agreement, a preset algorithm, or a preset policy. For example, if the configuration information of the time window a2 includes: the starting position of the time window a2, the length and / or ending position of the time window a2 can be determined by the network side device 1 based on a protocol agreement, a preset algorithm, or a preset policy.

[0780] It should be noted that the time window a2 may not be periodic but one-time (one shop).

[0781] In a third embodiment, the above two embodiments may be combined. In this case, the network side device 1 may sense the second cell in the following manner: after the first cell sends cell-related information, after a time interval t2, the second cell is sensed within a time window a2.

[0782] The method for determining the time interval t2 and the method for determining the time window a2 in this embodiment can refer to the above examples and will not be described in detail here.

[0783] In a fourth embodiment, the time interval, time window, etc. in the above embodiments may also be carried by a perception trigger indication, and the network side device 1 may determine the above time interval, time window, etc. according to the time information included in the perception trigger indication, and then sense the second cell. Based on the above description, the perception trigger indication may be carried by the cell related information, or may be carried by the perception related information associated with the cell related information, or may not be carried in the perception related information, but the network side device 1 may send the perception trigger indication to the terminal before or after sending the cell related information.

[0784] In the fifth embodiment, the perception trigger indication may also carry other time information to indicate the time for perception to the terminal. Accordingly, the network side device 1 may also perceive the second cell according to the time information carried by the perception trigger indication.

[0785] In the sixth embodiment, before the network side device 1 senses the second cell, the step of the network side device 1 determining the start time of the sensing may be included. Accordingly, the network side device 1 may sense the second cell according to the determined start time of the sensing.

[0786] At this time, determining the start time of perception can be achieved in the following ways:

[0787] Determine the sensing start time according to the effective time of the cell-related information; or,

[0788] Determine the sensing start time according to the sending time of the cell related information; or,

[0789] Determine the sensing start time according to the reception time of the confirmation message of the cell related information; or,

[0790] When the cell-related information is a beam update response, the sensing start time is determined according to the reception time of the beam update request; or,

[0791] When the cell-related information is a beam update response, the sensing start time is determined according to the beam update completion time; or,

[0792] When the cell-related information is in TCI state, the sensing start time is determined according to the time when the TCI state switching is completed; or,

[0793] When the cell-related information is a cell switching command, the sensing start time is determined according to the time when the cell switching is completed; or,

[0794] When the cell-related information is a cell activation command, the sensing start time is determined according to the time when the cell activation is completed.

[0795] In another embodiment provided in the present application, Figure 6 The method shown may also include the following steps:

[0796] Send perception enabling indication information, where the perception enabling indication information indicates cell-related information including information of the second cell for triggering perception.

[0797] Optionally, this step may be performed before step 601 .

[0798] By executing this step, the network side device 1 can determine whether the cell-related information is used to trigger perception according to actual needs, and send the above-mentioned perception enable indication information to the terminal when the cell-related information is needed to trigger perception, thereby making the perception triggering method more flexible.

[0799] Figure 6 In the method shown, when the cell-related information sent by the network side device 1 in the first cell includes information of the second cell, the terminal can be triggered to perceive the second cell, thereby associating the cell update behavior with the perception behavior. By utilizing the association relationship, when the cell update behavior occurs, the perception behavior can be started without the need for additional transmission of the signaling required for the perception behavior. In this way, communication-assisted perception is realized in the interawareness integrated system, the perception process is accelerated, the signaling overhead and delay of the perception process are reduced, the terminal surrounding environment information is obtained in a timely manner, the environmental map on the network side is updated, and the communication performance is improved.

[0800] Figure 7 In the embodiment of the present application shown in the figure, after the terminal switches to the second cell, the network side device 2 of the second cell can cooperate with Figure 5A The terminal in senses the second cell.

[0801] Figure 7 The method shown can be executed by the network side device 2. Figure 7 As shown, the method may include:

[0802] Step 701: perceive the second cell according to the perception-related information.

[0803] In this step, the perception-related information used by the network-side device 2 for perception may be sent by the core network server, the network-side device 1 or the terminal to the network-side device 2, or may be predefined in the network-side device 2 according to the protocol, or may be associated with the cell-related information sent by the network-side device 1 to the network-side device 2. Optionally, the above-mentioned cell-related information may be, for example, a beam update response, a TCI status, a cell switching command, a cell activation command, etc.

[0804] When the network side device 2 sends the perception related information to the network side device 1, the network side device 1 may indicate the perception related information to the terminal, thereby also achieving synchronization of the perception related information between the network side device 2 and the terminal.

[0805] When the perception-related information used by the network-side device 2 includes multiple pieces of information, the above-mentioned multiple configuration methods may be combined to implement the configuration of the perception-related information in the network-side device 2. For example, some items of the perception-related information may be configured by the core network server for the network-side device 2, and some items may be sent by the network-side device 1 to the network-side device 2.

[0806] Optionally, when perception-related information is predefined in the network side device 2 according to the protocol, or when the core network server, the network side device 1 or the terminal sends perception-related information to the network side device 2, or the network side device 2 sends perception-related information to the network side device 1, the above-mentioned perception-related information may indicate at least one of the following information: perception mode, perception signal set, perception signal resource, perception signal configuration, perception report configuration.

[0807] When the cell-related information sent by the network side device 1 to the network side device 2 is associated with the perception-related information, the perception-related information may indicate at least one of the following information: perception association status, perception trigger indication, perception mode, perception signal set, perception signal resource, perception signal configuration, and perception report configuration.

[0808] For the realization of associating cell-related information with perception-related information, please refer to Figure 5A The realization of associating the cell-related information with the perception-related information mainly differs in that the cell-related information sent by the network side device 1 to the terminal is replaced by the cell-related information sent by the network side device 1 to the network side device 2.

[0809] Optionally, the perception trigger indication may be carried by the perception related information, or may not be carried in the perception related information, but is sent by the network side device 1 to the network side device 2 independently of the perception related information.

[0810] For example:

[0811] The perception association status can be used to indicate to the network side device 2 that the cell-related information subsequently sent by the network side device 1 is associated with the perception-related information. At this time, the perception-related information associated with the cell-related information can only indicate the perception association status, so that the network side device 2 can know based on the perception association status that the cell-related information subsequently sent by the network side device 1 to the network side device 2 is associated with the perception-related information. At this time, the perception information associated with the cell-related information subsequently sent by the network side device 1 to the network side device 2 can indicate at least one of the perception trigger indication, the perception mode, the perception signal set, the perception signal resource, the configuration of the perception signal, and the configuration of the perception report.

[0812] Alternatively, the sensing association state is used to indicate whether the relevant information of the cell is associated with the sensing related information. When the sensing association state indicates that the relevant information of the cell is associated with the sensing related information, the network side device 2 can further learn the sensing related information associated with the cell related information. The associated sensing information can be pre-configured by the network side device 1, or indicated by the network side device 1 in the cell related information. At this time, the sensing related information can also indicate at least one of a sensing mode, a sensing signal set, a sensing signal resource, a sensing signal configuration, a sensing report configuration, and a sensing trigger indication.

[0813] Alternatively, if the network side device 2 has already learned in advance through the core network server configuration or protocol pre-definition that there is only one set of perception configurations (including: one perception mode, one perception signal set, and one perception report configuration), the perception-related information may only indicate the perception association state, without indicating at least one of the perception mode, perception signal set, perception signal resource, perception signal configuration, perception report configuration, and perception trigger indication.

[0814] When the perception-related information associated with the cell-related information indicates at least one of the perception mode, the perception signal set, the perception signal resource, the configuration of the perception signal, and the configuration of the perception report, if the cell-related information also includes a perception trigger indication, the network side device 2 may perform perception according to the perception trigger indication using information such as the perception mode, the perception signal, or the perception report, or the network side device 1 may send a perception trigger indication to the network side device 2 before or after indicating the cell-related information, and the network side device 2 may perform perception according to the perception trigger indication using information such as the perception mode, the perception signal, or the perception report indicated by the perception-related information associated with the cell-related information.

[0815] If the network side device 2 has already known the sensing mode, sensing signal set, sensing signal resource, sensing signal configuration, sensing report configuration and other information in advance through the core network server configuration or protocol pre-definition, and the network side device 1 hopes that the network side device 2 will sense after receiving the cell related information, then the cell related information may only indicate the sensing trigger indication. If the network side device 2 has already known the sensing mode in advance through the core network server configuration or protocol pre-definition, and the network side device 1 hopes that the network side device 2 will sense after receiving the cell related information, then the sensing related information may indicate at least one of the sensing trigger indication, sensing signal set, sensing signal resource, sensing signal configuration and sensing report configuration. Similarly, if the network side device 2 has already known the sensing mode and sensing signal set in advance through the core network server configuration or protocol pre-definition, and the network side device 1 hopes that the network side device 2 will sense after receiving the cell related information, then the sensing related information may indicate at least one of the sensing trigger indication and sensing report configuration. Other similar implementations are not listed one by one.

[0816] If, through the core network server configuration or protocol pre-definition, the network side device 2 receives cell-related information or receives cell-related information associated with perception-related information and performs perception based on the perception-related information, then the perception-related information associated with the cell-related information may not indicate a perception trigger indication, but only indicates at least one of the perception association status, perception mode, perception signal set, perception signal resources, perception signal configuration, and perception report configuration.

[0817] The triggering condition for the network side device 2 to execute step 701 may be explicitly or implicitly indicated by the network side device 1, the core network server or the terminal to the network side device 2.

[0818] An explicit indication method may, for example, be that the network side device 1, the core network server or the terminal sends a perception trigger indication to the network side device 2, thereby triggering the network side device 2 to perform perception; or, the network side device 1, the core network server or the terminal sends time information to the network side device 2 to indicate the time for the network side device 2 to perform perception, etc.

[0819] An implicit indication method may be, for example, that the network side device 1, the core network server or the terminal sends a certain preset information to the network side device 2, thereby implicitly triggering the network side device 2 to perceive, for example, after the terminal sends access information to the network side device 2, the network side device 2 perceives; or, after the network side device 1, the core network server or the terminal sends a certain preset information to the network side device 2, the network side device 2 determines the time for perception based on a preset rule, thereby implicitly triggering perception; or, the network side device 2 determines the time for perception based on the time information of a preset message (for example, the receiving time, the effective time, the confirmation time, or the completion time, etc.), thereby implicitly triggering perception, for example, the receiving time, the effective time, the confirmation time, or the completion time of the cell switching command is used as the starting time for perception, or, after a preset time has passed after the TCI state switching is completed, the beam update is completed, etc., the network side device 2 starts to perceive.

[0820] For example, if before step 701, the network side device 2 receives the cell related information sent by the network side device 1, the sensing of the second cell in this step can be implemented in the following manner.

[0821] In the first embodiment, the network side device 2 may sense the second cell in the following manner:

[0822] After receiving the cell-related information, after a time interval t3, the second cell is sensed.

[0823] Optionally, the time interval t3 may be configured by the core network server or the network side device 1 for the network side device 2, or may be pre-agreed upon by a protocol, or may be determined in real time by the network side device 2 based on a preset algorithm or policy.

[0824] Optionally, when the above-mentioned time interval t3 is configured by the core network server or the network side device 1 for the network side device 2, the following steps may also be included before step 701: receiving configuration information of the time interval t3, and the configuration information of the time interval t3 is used to indicate the length of the above-mentioned time interval t3.

[0825] Optionally, the network side device 2 may configure the time interval t3 to the terminal. In this case, the following steps may be included before step 701: sending configuration information of the time interval t3, where the configuration information of the time interval t3 is used to indicate the length of the time interval t2.

[0826] Optionally, the start time of the time interval t3 may be: the time of receiving the cell-related information, the time of taking effect of the cell-related information, or the time of sending a confirmation message of the cell-related information.

[0827] Optionally, when the cell-related information is a beam update response, the starting time of the time interval t3 may also be: the time when the beam update request is received, or the time when the beam update is completed.

[0828] Optionally, when the cell-related information is in TCI state, the starting time of the time interval t3 may also be: the time when the TCI state switching is completed.

[0829] Optionally, when the cell-related information is a cell switching command, the start time of the time interval t3 may also be: the time when the cell switching is completed.

[0830] Optionally, when the cell-related information is a cell activation command, the start time of the time interval t3 may also be: the time when the cell activation is completed.

[0831] In the second embodiment, the network side device 2 may sense the second cell in the following manner:

[0832] After receiving the cell-related information, the second cell is sensed within the time window a3.

[0833] Optionally, time window a3 can be configured by the core network server or network side device 1 for the network side device 2, or can be pre-agreed upon by a protocol, or can be determined in real time by the network side device 2 based on a preset algorithm or strategy, or can be determined by a combination of at least two of the above three methods.

[0834] For example, the time window a3 can be determined by at least two of the starting position of the time window a3, the length of the time window a3, and the ending position of the time window a3. At this time, the at least two pieces of information used to determine the time window a3 can be partially determined by the core network server for the network side device 2, and partially determined by the network side device 2 based on a protocol agreement, a preset algorithm, or a preset strategy.

[0835] Optionally, the core network server or the network side device 1 may configure the information of the time window a3 for the network side device 2 so that the network side device 2 determines the time window a3, and the following steps may be further included before step 701:

[0836] Configuration information of the time window a3 is received, where the configuration information of the time window a3 is used to indicate the time window a3.

[0837] Optionally, the network side device 2 may configure the information of the time window a3 to the terminal. In this case, the following steps may be included before step 701: sending the configuration information of the time window a3, where the configuration information of the time window a3 is used to indicate the above-mentioned time window a3.

[0838] Optionally, the configuration information of the time window a3 includes at least one of the following: the starting position of the time window a3, the length of the time window a3, and the ending position of the time window a3. When the configuration information of the time window a3 includes one of the starting position of the time window a3, the length of the time window a3, and the ending position of the time window a3, other information used to determine the time window a3 can be determined by the network side device 2 based on a protocol agreement, a preset algorithm, or a preset policy. For example, if the configuration information of the time window a3 includes: the starting position of the time window a3, the length and / or ending position of the time window a3 can be determined by the network side device 2 based on a protocol agreement, a preset algorithm, or a preset policy.

[0839] It should be noted that the time window a3 may not be periodic but one-time (one shop).

[0840] In a third embodiment, the above two embodiments may be combined. In this case, the network side device 2 may sense the second cell in the following manner:

[0841] After receiving the cell related information, after a time interval t3, sensing is performed according to the sensing related information within the time window a3.

[0842] The method for determining the time interval t3 and the method for determining the time window a3 in this example can refer to the above examples and will not be described in detail here.

[0843] In the fourth embodiment, the time interval, time window, etc. in the above example may also be carried by the perception trigger indication sent by the core network server, network side device 1 or terminal to the network side device 2, and the network side device 2 may determine the above time interval, time window, etc. according to the time information included in the perception trigger indication, and then perform perception. Based on the above description, the perception trigger indication may be carried by the perception related information associated with the cell related information, or may not be carried in the perception related information, but the core network server, network side device 1 or terminal sends the perception trigger indication to the network side device 2 before or after the network side device 1 sends the cell related information.

[0844] In the fifth embodiment, the perception trigger indication sent by the core network server, network side device 1 or terminal to the network side device 2 may also carry other time information to indicate the time for perception to the network side device 2. Correspondingly, the network side device 2 may also perceive the second cell according to the time information carried by the perception trigger indication and the perception-related information.

[0845] In the sixth embodiment, a step of determining a start time of perception may be included before step 701 .

[0846] Optionally, determining the start time of perception may be implemented in the following manner:

[0847] Determine the sensing start time according to the effective time of the cell-related information; or,

[0848] Determine the sensing start time according to the reception time of the cell related information; or,

[0849] Determine the sensing start time according to the sending time of the confirmation message of the cell related information; or,

[0850] When the cell-related information is a beam update response, the sensing start time is determined according to the reception time of the beam update request; or,

[0851] When the cell-related information is a beam update response, the sensing start time is determined according to the beam update completion time; or,

[0852] When the cell-related information is in TCI state, the sensing start time is determined according to the time when the TCI state switching is completed; or,

[0853] When the cell-related information is a cell switching command, the sensing start time is determined according to the time when the cell switching is completed; or,

[0854] When the cell-related information is a cell activation command, the sensing start time is determined according to the time when the cell activation is completed.

[0855] In another embodiment provided by the present application, if before step 701, the network side device 2 receives the cell related information sent by the network side device 1, Figure 7 The method shown may also include the following steps:

[0856] A perception enabling indication information 1 is received, where the perception enabling indication information 1 indicates that cell-related information including information of a second cell is used to trigger perception.

[0857] Optionally, this step may be performed before the step in which the network side device 2 receives the cell related information sent by the network side device 1 .

[0858] By executing this step, the network side device 1 can determine whether the cell-related information is used to trigger perception according to actual needs, and send the above-mentioned perception enable indication information 1 to the network side device 2 when the cell-related information is needed to trigger perception, thereby making the perception triggering method more flexible.

[0859] In another example, if before step 701, the network side device 2 receives perception-related information sent by the core network server, the network side device 1 or the terminal, the specific implementation of the network side device 2 perceiving the second cell can refer to the specific implementation of the network side device 2 perceiving the second cell when the network side device 2 receives the cell-related information sent by the network side device 1 in the previous example. The main difference lies in replacing the cell-related information in each embodiment with perception-related information, which will not be repeated here.

[0860] In another embodiment provided by the present application, if before step 701, the network side device 2 receives the perception related information, Figure 7 The method shown may also include the following steps:

[0861] A perception enabling indication information 2 is received, where the perception enabling indication information 2 indicates that the perception related information is used to trigger perception.

[0862] The above-mentioned perception enabling indication information 2 can be sent to the network side device 2 by the core network server, the network side device 1 or the terminal.

[0863] Optionally, this step may be performed before the step in which the network side device 2 receives the perception-related information.

[0864] By executing this step, the core network server, network side device 1 or terminal can determine whether perception-related information is used to trigger perception according to actual needs, and send the above-mentioned perception enable indication information 2 to the network side device 2 when perception-related information is needed to trigger perception, thereby making the perception triggering method more flexible.

[0865] Figure 7 In the method shown, the network side device 2 can cooperate with the terminal to perceive the second cell of the network side device 2 based on the perception-related information, thereby associating the cell update behavior with the perception behavior. By utilizing the association relationship, the perception behavior can be initiated when the cell update behavior occurs, without the need for additional transmission of the signaling required for the perception behavior. Communication-assisted perception is realized in the integrated synaesthesia system, accelerating the perception process, reducing the signaling overhead and delay of the perception process, timely obtaining the terminal's surrounding environment information, updating the network side's environmental map, and improving communication performance.

[0866] The following is based on the above Figure 5A to Figure 7 The method shown, through Figures 8A to 10 An exemplary description is given of the implementation of the cooperation between the network side device 1 and the terminal to sense the second cell.

[0867] Fig. 8A In the illustrated embodiment of the present application, after the network side device 1 sends the cell-related information including the information of the second cell to the terminal, the network side device 1 and the terminal sense the second cell.

[0868] This method can be applied to a terminal that resides in a first cell and senses the second cell when the terminal has not switched to the second cell.

[0869] See also Fig. 8A , the method may include:

[0870] Step 802: The network side device 1 sends cell related information to the terminal in the first cell.

[0871] It can be understood that the network side device 1 may include the information of the second cell in the cell related information sent from the first cell to the terminal, or may not include the information of the second cell. In the embodiment of the present application, the example of including the information of the second cell in the cell related information is taken as an example.

[0872] Step 804A: The network side device 1 determines that the cell-related information includes information about the second cell.

[0873] Step 804B: The terminal determines that the cell-related information includes information about the second cell.

[0874] Step 806: The network side device 1 and the terminal sense the second cell.

[0875] The implementation of the above steps 802 and 804B can refer to Figure 5A The corresponding description in step 804A is not repeated here. The implementation of the network side device 1 determining that the cell related information includes the information of the second cell can also refer to Figure 5A The implementation of the terminal determining that the cell-related information includes the information of the second cell is mainly different in that the execution subject is changed from the terminal to the network side device 1, which will not be repeated here.

[0876] In step 806, the network side device 1 and the terminal may respectively sense the second cell according to the perception related information.

[0877] In the first example, the cell-related information sent by the network side device 1 to the terminal in step 802 can be associated with the perception-related information. Then, in step 806, the network side device 1 and the terminal can sense the second cell according to the perception-related information associated with the cell-related information. At this time, the implementation of the cell-related information and the perception-related information can refer to Figure 5A The corresponding description in is not repeated here.

[0878] In the second example, the cell-related information sent by the network-side device 1 to the terminal in step 802 may not be associated with the perception-related information. In this case, the network-side device 1 may perform the step of sending the perception-related information to the terminal before step 806, and the network-side device 1 and the terminal may sense the second cell based on the perception-related information in step 806. It should be noted that the step of sending the perception-related information to the terminal by the network-side device 1 may be performed before step 806, and is not limited to the execution order between step 802, step 804A, and step 804B.

[0879] In the third example, the network side device 1 and the terminal may predefine the perception related information according to the protocol, so that in step 806, the network side device 1 and the terminal may respectively perceive the second cell according to the locally predefined perception related information.

[0880] In a fourth example, two or more of the above three embodiments may be combined. Taking the combination of the three embodiments as an example, some of the sensing related information is associated with the cell related information, some of the information is sent to the terminal by the network side device 1 independently of the cell related information, and some of the information is predefined in advance according to the protocol.

[0881] The realization of the network side device 1 sensing the second cell in step 806 can refer to Figure 6 The corresponding descriptions in the illustrated embodiments are not repeated here.

[0882] The implementation of the terminal sensing the second cell in step 806 can refer to Figure 5A The corresponding descriptions in the illustrated embodiments are not repeated here.

[0883] It should be noted that the perception-related information used by the network-side device 1 and the terminal to perceive the second cell in step 806 may be the same or different, as long as they can cooperate to complete the perception of the second cell.

[0884] It should be noted that the method for determining the perception time (eg, the perception start time) when the network side device 1 and the terminal perceive the second cell in step 806 may be the same or different, as long as the perception of the second cell can be completed synchronously.

[0885] In another embodiment provided by the present application, the following steps may be further included before step 802:

[0886] The network side device 1 sends perception enabling indication information to the terminal, where the perception enabling indication information indicates that cell-related information including information of the second cell is used to trigger perception.

[0887] By executing this step, the network side device 1 can determine whether the cell-related information is used to trigger perception according to actual needs, and send the above-mentioned perception enable indication information to the terminal when the cell-related information is needed to trigger perception, thereby making the perception triggering method more flexible.

[0888] Below, through Figure 8B and Figure 8C An exemplary description is given of the implementation of the terminal and the network side device 1 sensing the second cell in different sensing modes.

[0889] exist Figure 8B In the process, the network side device 1 sends a perception signal, and the terminal measures the perception signal.

[0890] like Figure 8B As shown, step 806 can be specifically implemented through the following steps S11 to S15.

[0891] S11: Network side device 1 sends a perception signal.

[0892] In an embodiment of the present application, the time when the network side device 1 perceives in step 601 can be used as the time when the network side device 1 sends the perception signal in this step. The specific determination method can refer to step 601 and will not be repeated here.

[0893] In an example, if the perception-related information associated with the cell-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step, the network-side device 1 may send a perception signal based on the perception-related information.

[0894] In another example, if the cell-related information is not associated with the perception-related information, or the perception-related information associated with the cell-related information does not indicate information such as a perception signal set, a perception signal resource, and a configuration of a perception signal resource, but the network side device 1 has pre-configured the terminal with information such as a perception signal set, a perception signal resource, and / or a configuration of a perception signal resource, then in this step, the network side device 1 can send a perception signal based on the above information pre-configured for the terminal.

[0895] S12: The terminal measures the sensing signal and obtains a sensing result.

[0896] In the embodiment of the present application, the time when the terminal performs perception in step 502 may be used as the time when the terminal measures the perception signal in this step. The specific determination method may refer to step 502 and will not be repeated here.

[0897] In an example, if the perception-related information associated with the cell-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step, the terminal may measure the perception signal based on the perception-related information.

[0898] In another example, if the perception-related information associated with the cell-related information does not indicate information such as a perception signal set, a perception signal resource, and a configuration of a perception signal resource, but the network side device 1 has pre-configured information such as a perception signal set, a perception signal resource, and / or a configuration of a perception signal resource for the terminal, then in this step, the terminal can measure the perception signal based on the pre-configured information.

[0899] S13: The terminal generates a perception report according to the perception result, and sends the perception report to the network side device 1.

[0900] In an example, if the perception-related information associated with the cell-related information includes perception report indication information, then in this step, the terminal may generate a perception report according to the perception report indication information and the perception result.

[0901] In another example, if the sensing related information associated with the cell related information does not include the sensing report indication information, but the network side device 1 is previously configured only for the sensing mode (for example Figure 8B In the perception mode in which the network side device 1 sends a perception signal, the terminal perceives the measurement and reports the perception mode of the network side device 1), a perception report in one format or a perception report configuration is configured. Then, in this step, the terminal can generate a perception report based on the perception result and the pre-configured perception report information.

[0902] It should be noted that when the terminal generates a perception report based on the perception result, all results or some of the better results in the perception result can be carried in the perception report. In other words, when the terminal measures the perception signal in step S12, it can only measure the parameters required in the perception report to obtain the perception result, or it can measure the parameters required in the perception report and other parameters other than the parameters required in the perception report to obtain the perception result, which is not limited in the embodiment of the present application.

[0903] S14: The network side device 1 sends the perception report to the network side device 2.

[0904] S15A: The network-side device 1 updates the environment map according to the perception report.

[0905] S15B: The network measuring device 2 updates the environment map according to the sensing report.

[0906] Optionally, the network side device 1 and the network side device 2 may be access network devices such as base stations respectively. Environmental maps may be maintained in the network side device 1, the network side device 2 and the core network server respectively. The environmental map maintained by the core network server may include environmental maps maintained by access network devices such as the network side device 1 and the network side device 2. In other words, the environmental maps maintained by access network devices such as the network side device 1 and the network side device 2 may be part of the environmental map maintained by the core network server.

[0907] Optionally, the network side device 1 or the network side device 2 may also send the perception report to the core network server, so that the core network server may update the environment map maintained by itself according to the perception report.

[0908] exist Figure 8C In the process, the terminal sends a perception signal, and the network side device 1 measures the perception signal.

[0909] like Figure 8C As shown, step 806 can be implemented by the following steps S21 to S24.

[0910] S21: The terminal sends a perception signal.

[0911] In the embodiment of the present application, the time when the terminal performs perception in step 502 may be used as the time when the terminal sends the perception signal in this step. The specific determination method may refer to step 502 and will not be repeated here.

[0912] In an example, if the perception-related information associated with the cell-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step, the terminal may send a perception signal based on the perception-related information.

[0913] In another example, if the perception-related information associated with the cell-related information does not indicate information such as a perception signal set, a perception signal resource, and a configuration of a perception signal resource, but the network side device 1 has pre-configured information such as a perception signal set, a perception signal resource, and / or a configuration of a perception signal resource for the terminal, then in this step, the terminal can send a perception signal based on the pre-configured information.

[0914] S22: The network side device 1 measures the sensing signal to obtain a sensing result.

[0915] In an embodiment of the present application, the time for the network side device 1 to perceive in step 601 may be used as the time for the network side device to measure the perception signal in this step. The specific determination method may refer to step 601 and will not be repeated here.

[0916] In an example, if the perception-related information associated with the cell-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step, the network-side device 1 may measure the perception signal based on the perception-related information.

[0917] In another example, if the perception-related information associated with the cell-related information does not indicate information such as a perception signal set, a perception signal resource, and a configuration of a perception signal resource, but the network side device 1 has pre-configured information such as a perception signal set, a perception signal resource, and / or a configuration of a perception signal resource for the terminal, then in this step, the network side device 1 can measure the perception signal based on the pre-configured information.

[0918] S23: The network side device 1 sends the sensing result to the network side device 2.

[0919] S24A: The network-side device 1 updates the environment map according to the perception result.

[0920] S24B: The network-side device 2 updates the environment map according to the perception result.

[0921] Optionally, the network side device 1 or the network side device 2 may also send the perception result to the core network server, so that the core network server may update the environment map maintained by itself according to the perception result.

[0922] The implementation of the above steps can refer to Figure 5A to Figure 7 The corresponding descriptions in the illustrated embodiments are not repeated here.

[0923] It should be noted that in other perception modes provided in the embodiment of the present application, the terminal may also send the perception report to the network side device 2, or send it to the network side device 1 and the network side device 2 at the same time, etc., and its specific implementation can refer to the above Figure 8B and Figure 8C , the embodiments of the present application are no longer listed one by one.

[0924] In another perception method provided in an embodiment of the present application, the network side device 1 configures perception configuration information for the terminal. In this case, the following step 800 may be included before step 802 of the above embodiment. Fig. 9A ,by Fig. 8A The method shown includes step 800 before step 802 as an example.

[0925] Step 800: The network side device 1 sends perception configuration information to the terminal.

[0926] Optionally, the above-mentioned perception configuration information can be sent by the core network server to the network side device 1, and then sent by the network side device 1 to the terminal, that is, before this step, it can also include: the core network server sends the perception configuration information to the network side device 1.

[0927] Optionally, the perception configuration information may include at least one of the following: candidate perception mode configuration information, candidate perception signal configuration information, and candidate perception report configuration information.

[0928] Optionally, the candidate sensing mode configuration information may be used to configure at least one sensing mode. The candidate sensing mode configuration information may include a sensing mode identifier. Different sensing modes have different sensing mode identifiers.

[0929] Optionally, the candidate perceptual signal configuration information may be used to configure a perceptual signal resource, a perceptual signal resource set, or a perceptual signal resource configuration. Optionally, the candidate perceptual signal configuration information may configure at least one perceptual signal, at least one perceptual signal resource, at least one perceptual signal resource set, or at least one perceptual signal resource configuration. Optionally, the perceptual signal configuration information may include: a perceptual signal resource identifier, a resource set identifier, or a resource configuration identifier. Different perceptual signals have different resource identifiers.

[0930] Optionally, the candidate perception report configuration information may be used to configure a perception report. Optionally, the candidate perception report configuration information may be used to configure at least one format of perception report or at least one type of perception report. Optionally, the candidate perception report configuration information may include: an identifier of a perception report configuration. Perception reports of different formats have different perception report identifiers or identifiers of different perception report configurations. Different perception reports have different perception report identifiers or identifiers of different perception report configurations.

[0931] At this time, the perception related information in the embodiment of the present application may include:

[0932] a sensing mode flag indicating a sensing mode; and / or,

[0933] a resource identifier, a resource set identifier, or a resource configuration identifier of a perception signal, indicating the perception signal; and / or,

[0934] The flag of the perception report configuration, indicating perception reporting.

[0935] Correspondingly, in step 806, the terminal may obtain perception configuration information corresponding to the perception related information from the perception configuration information according to the perception related information, and perform perception according to the perception configuration information corresponding to the above perception related information.

[0936] Since the above-mentioned perception-related information is indicated to the terminal by the network-side device 1, the network-side device 1 may use the same or different method as the terminal to determine the perception configuration information and perform perception, which is not limited in the embodiments of the present application.

[0937] Optionally, the perception configuration information may also include: an association relationship between a perception signal and a perception report. Optionally, multiple perception signal resources or multiple perception signal resource sets or multiple perception signal resource configurations may correspond to a perception report of one format or one configuration identifier, and perception reports of different formats or different configuration identifiers may correspond to one perception signal resource or one perception signal resource set or one perception signal resource configuration. Optionally, the above association relationship may be specifically recorded through a correspondence relationship between a resource identifier or a resource set identifier or a resource configuration identifier of a perception signal and a perception report configuration identifier.

[0938] In an example, if the candidate perception signal configuration information in the perception configuration information configures only one perception signal resource or one perception signal resource set or one perception signal resource configuration, and the candidate perception report configuration information only includes one perception report configuration, or, if the candidate perception signal configuration information in the perception configuration information configures only one perception signal resource or one perception signal resource set or one perception signal resource configuration, and the perception configuration information includes an association relationship between the perception signal and the perception report, or, if the candidate perception signal configuration information in the perception configuration information includes only one perception report configuration and the perception configuration information includes an association relationship between the perception signal and the perception report, then, the indication information of the perception signal and the indication information of the perception report in the perception-related information can be omitted.

[0939] In another example, if the perception-related information includes: an association relationship between a perception signal and a perception report, the perception-related information may include: perception signal indication information or perception report indication information, so that the terminal can determine the perception signal that the terminal needs to measure and the relevant information of the perception report to be reported based on the above-mentioned association relationship.

[0940] In another example, if the perception-related information includes: perception report indication information, the default perception mode can be that the network-side device 1 sends a perception signal, and the terminal measures and reports the perception result, and the perception mode indication information in the perception-related information can be omitted.

[0941] When the cell-related information and the perception-related information in the above embodiment are specifically related to each other, the network-side device 1 may send corresponding relationship indication information to the terminal to indicate the corresponding relationship between the cell-related information and the perception-related information. In this case, in another perception method provided in the embodiment of the present application, the following step 801 may be included before step 802. Fig. 9B ,by Fig. 9A The method shown also includes step 801 as an example.

[0942] Step 801: the network side device 1 sends corresponding relationship indication information to the terminal, where the corresponding relationship indication information is used to indicate the corresponding relationship between the cell related information and the perception related information.

[0943] Correspondingly, after receiving the cell-related information in step 804, the terminal can determine the perception-related information corresponding to the cell-related information according to the above correspondence, and then in step 806, the terminal can perceive the second cell according to the perception-related information corresponding to the cell-related information.

[0944] The above embodiment uses the cell-related information received in the first cell and including the information of the second cell to trigger the network side device 1 and the terminal to perceive the second cell as an example. In another perception method provided in the embodiment of the present application, the network side device 1 and the terminal can be triggered to perceive by a perception trigger indication sent independently of the above cell-related information. At this time, the following step 805 can be added between step 804 and step 806 in the above embodiment. Fig. 9C ,by Fig. 8A Take the method shown in the figure as an example in which the following step 805 is added between step 804 and step 806.

[0945] Step 805: The network side device 1 sends a perception trigger indication to the terminal.

[0946] At this time, the specific implementation of the network side device 1 sensing the second cell in step 806 can refer to step 601. Optionally, the step of sending the cell related information in the specific implementation of the network side device 1 sensing the second cell in step 601 can be replaced with the step of sending the sensing trigger indication.

[0947] At this time, the specific implementation of the terminal sensing the second cell in step 806 may refer to step 502. Optionally, the step of receiving cell-related information in the specific implementation of the terminal sensing the second cell in step 502 may be replaced with the step of receiving a sensing trigger indication.

[0948] In the embodiment of the present application, the network side device 1 and the terminal are triggered to sense the second cell through a perception trigger indication sent independently of the above-mentioned cell-related information, so that the perception triggering method is more diverse and flexible.

[0949] It should be noted that as long as the above-mentioned step 805 is located before step 806, the execution order of step 802, step 804A, and step 804B is not limited. For example, in other embodiments provided in the present application, the above-mentioned step 805 can also be located before step 802, or between step 802 and step 804A (or step 804B).

[0950] In another embodiment provided by the present application, the step of determining the start time of the perception by the network side device 1 and the terminal may be further included. In this case, the following steps 1001A and 1001B may be added between step 804 and step 806 of the above embodiment. Fig.10 ,by Fig. 8A Take the method shown as an example where step 1001A and step 1001B are added between step 804 and step 806.

[0951] Step 1001A: The network side device 1 determines the start time of perception.

[0952] Step 1001B: The terminal determines the start time of perception.

[0953] If step 806 passes Figure 8B In the implementation of S11 to S15 shown in , the starting time of perception determined by the network side device 1 in step 1001A may specifically be the starting time when the network side device 1 sends the perception signal, and the starting time of perception determined by the terminal in step 1001B may specifically be the starting time for measuring the perception signal.

[0954] If step 806 passes Figure 8C In the implementation of S21 to S24 shown in , the starting time of perception determined by the network side device 1 in step 1001A may specifically be the starting time for the network side device 1 to measure the perception signal, and the starting time of perception determined by the terminal in step 1001B may specifically be the starting time for sending the perception signal.

[0955] The implementation of the network side device 1 determining the start time of perception in step 1001A can refer to the corresponding description in step 601, which will not be repeated here.

[0956] Optionally, if the perception trigger indication carries time information, the network side device 1 in this step may also determine the start time of perception according to the time information carried by the perception trigger indication. The perception trigger indication may be included in the perception related information associated with the cell related information, or the network side device 1 may send the perception trigger indication before or after sending the cell related information.

[0957] The implementation of the terminal determining the start time of perception in step 1001B can refer to the corresponding description in step 502, which will not be repeated here.

[0958] Optionally, if the perception trigger indication carries time information, then in this step, the terminal may also determine the start time of perception according to the time information carried by the perception trigger indication.

[0959] In the embodiment of the present application, the network side device 1 and the terminal respectively determine the start time of perception, so that perception can be started simultaneously based on the start time of perception.

[0960] It should be noted that the method by which the network side device 1 determines the start time of perception and the method by which the terminal determines the start time of perception can be the same or different, as long as the two are synchronized so that the network side device 1 and the terminal can cooperate to complete the perception.

[0961] The following is based on the above Figure 5A to Figure 7 The method shown, through Figures 11A to 12F An exemplary description is given of the implementation of the cooperation among the network side device 1, the network side device 2 and the terminal to sense the second cell.

[0962] Fig.11A In the illustrated embodiment of the present application, after the network side device 1 sends the cell-related information including the information of the second cell to the terminal, the network side device 2 and the terminal sense the second cell.

[0963] This method can be applied to the terminal sensing the second cell after switching from the first cell to the second cell.

[0964] Fig.11A is a flow chart of a sensing method provided in an embodiment of the present application, such as Fig.11A As shown, the method may include:

[0965] Step 1102: the network side device 1 sends first cell related information to the terminal in the first cell, where the first cell related information includes information about the second cell.

[0966] Step 1104: The terminal determines that the first cell related information received in the first cell includes the information of the second cell.

[0967] Step 1106: The terminal and network side device 2 sense the second cell.

[0968] The implementation of step 1102 and step 1104 can refer to Figure 5A The corresponding instructions in are not repeated here.

[0969] The implementation of the terminal sensing the second cell in step 1106 can refer to Figure 5A The corresponding instructions in are not repeated here.

[0970] In one example, the first cell related information sent by the network side device 1 to the terminal in the first cell in step 1102 may not be associated with the perception related information. Then in step 1106, the terminal may perceive the second cell according to the perception related information predefined in the terminal according to the protocol or pre-configured by the network.

[0971] In another example, in step 1102, the first cell related information sent by the network side device 1 to the terminal in the first cell can be associated with perception related information. Then in step 1106, the terminal can determine the perception related information associated with the first cell related information based on the first cell related information, and perceive the second cell based on the perception related information associated with the first cell related information.

[0972] The implementation of the network side device 2 sensing the second cell in step 1106 can refer to the corresponding description in step 701, which will not be repeated here.

[0973] Below, through Fig. 11B and Fig. 11C An exemplary description is given of the implementation of the terminal and the network side device 2 sensing the second cell in different sensing modes.

[0974] exist Fig. 11B In the process, the network side device 2 sends a perception signal, and the terminal measures the perception signal.

[0975] like Fig. 11B As shown, step 1106 can be specifically implemented through the following steps S31 to S34.

[0976] S31: Network side device 2 sends a perception signal.

[0977] In an embodiment of the present application, the time when the network side device 2 perceives in step 701 can be used as the time when the network side device 2 sends the perception signal in this step. The specific determination method can refer to step 701 and will not be repeated here.

[0978] In one instance, if the cell-related information sent by the network side device 1 to the network side device 2 is associated with the perception-related information, and the perception-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step, the network side device 2 can measure the perception signal based on the perception-related information.

[0979] In another instance, if the cell-related information sent by the network side device 1 to the network side device 2 is associated with the perception-related information, and the perception-related information does not indicate information such as the perception signal set, perception signal resources, and the configuration of the perception signal resources, but the network side device 1 or the core network server has pre-configured the network side device 2 with information such as the perception signal set, perception signal resources, and / or the configuration of the perception signal resources, then in this step, the network side device 2 can measure the perception signal based on the above-mentioned pre-configured information.

[0980] S32: The terminal measures the perception signal and obtains a perception result.

[0981] In the embodiment of the present application, the time when the terminal performs perception in step 502 may be used as the time when the terminal measures the perception signal in this step. The specific determination method may refer to step 502 and will not be repeated here.

[0982] In an example, if the cell-related information sent by the network side device 1 to the terminal is associated with the perception-related information, and the perception-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step, the terminal can measure the perception signal based on the perception-related information.

[0983] In another example, if the cell-related information sent by the network side device 1 to the terminal is associated with the perception-related information, and the perception-related information does not indicate information such as the perception signal set, the perception signal resources, and the configuration of the perception signal resources, but the network side device 1 has pre-configured the terminal with information such as the perception signal set, the perception signal resources, and / or the configuration of the perception signal resources, then in this step, the terminal can measure the perception signal based on the above-mentioned pre-configured information.

[0984] S33: The terminal generates a perception report according to the perception result, and sends the perception report to the network side device 2.

[0985] In an example, if the cell-related information sent by the network side device 1 to the terminal is associated with perception-related information, and the perception-related information includes perception report indication information, then in this step, the terminal can generate a perception report according to the perception report indication information and the perception result.

[0986] In another instance, if the cell-related information sent by the network side device 1 to the terminal is associated with perception-related information, and the perception-related information does not include perception report indication information, but the network side device 1 has pre-configured only one format of perception report or one perception report configuration for this perception mode (the network side device 2 sends a perception signal, and the terminal perceives the measurement and reports it to the network side device 2), then in this step, the terminal can generate a perception report based on the perception result and the pre-configured perception report information.

[0987] S34: The network-side device 2 updates the environment map according to the perception report.

[0988] Optionally, the network side device 2 may also send the perception report to the network side device 1 and / or the core network server, so that the network side device 1 and / or the core network server may update the environment map maintained by itself according to the perception report.

[0989] exist Fig. 11C In the process, the terminal sends a perception signal, and the network side device 2 measures the perception signal.

[0990] like Fig. 11CAs shown, step 1106 can be implemented by the following steps S21 to S23:

[0991] S41: The terminal sends a perception signal.

[0992] In the embodiment of the present application, the time when the terminal performs perception in step 502 may be used as the time when the terminal sends the perception signal in this step. The specific determination method may refer to step 502 and will not be repeated here.

[0993] In an example, if the cell-related information sent by the network side device 1 to the terminal is associated with the perception-related information, and the perception-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step the terminal may send a perception signal based on the perception-related information.

[0994] In another example, if the cell-related information sent by the network side device 1 to the terminal is associated with the perception-related information, and the perception-related information does not indicate information such as the perception signal set, perception signal resources, and the configuration of the perception signal resources, but the network side device 1 has pre-configured the terminal with information such as the perception signal set, perception signal resources, and / or the configuration of the perception signal resources, then in this step the terminal can send the perception signal based on the pre-configured information.

[0995] S42: The network side device 2 measures the sensing signal to obtain a sensing result.

[0996] In an embodiment of the present application, the time for the network side device 2 to perceive in step 701 can be used as the time for the network side device to measure the perception signal in this step. The specific determination method can refer to step 701 and will not be repeated here.

[0997] In one instance, if the cell-related information sent by the network side device 1 to the network side device 2 is associated with the perception-related information, and the perception-related information indicates a perception signal set, a perception signal resource and / or a configuration of a perception signal resource, then in this step, the network side device 2 can measure the perception signal based on the perception-related information.

[0998] In another instance, if the cell-related information sent by the network side device 1 to the network side device 2 is associated with the perception-related information, and the perception-related information does not indicate information such as the perception signal set, perception signal resources, and the configuration of the perception signal resources, but the network side device 1 or the core network server has pre-configured the network side device 2 with information such as the perception signal set, perception signal resources, and / or the configuration of the perception signal resources, then in this step, the network side device 2 can measure the perception signal based on the above-mentioned pre-configured information.

[0999] S43: The network-side device 2 updates the environment map according to the perception result.

[1000] Optionally, the network side device 2 may also send the perception result to the network side device 1 and / or the core network server, so that the network side device 1 and / or the core network server may update the environment map maintained by itself according to the perception result.

[1001] The implementation of the above steps can refer to Figure 5A to Figure 7 The corresponding descriptions in the illustrated embodiments are not repeated here.

[1002] It should be noted that, referring to the example of the perception mode in step 502, in other perception modes, the terminal may also send the perception report to the network side device 1, or send it to the network side device 1 and the network side device 2 at the same time, etc., and its specific implementation may refer to the above Fig. 11B and Fig. 11C , the embodiments of the present application are no longer listed one by one.

[1003] In another perception method provided by an embodiment of the present application, if the first cell-related information in the above embodiment is associated with the perception-related information, the network-side device 1 may configure the first perception configuration information for the terminal, so that the terminal can determine the perception-related information associated with the first cell-related information according to the first perception configuration information. At this time, the following step 1100 may be included before step 1102 of the above embodiment. Fig. 12A ,by Fig.11A The method shown includes step 1100 before step 1102 as an example.

[1004] Step 1100: The network side device 1 sends first perception configuration information to the terminal.

[1005] The implementation of this step can refer to the corresponding description in step 800, which will not be repeated here.

[1006] Correspondingly, in step 1106, the terminal may obtain perception configuration information corresponding to the perception related information from the first perception configuration information based on the perception related information, and perform perception based on the perception configuration information corresponding to the above perception related information.

[1007] In the above embodiment, when the first cell-related information is associated with the perception-related information, specifically, the first cell-related information and the perception-related information have a corresponding relationship, the network-side device may send corresponding relationship indication information to the terminal to indicate the corresponding relationship between the first cell-related information and the perception-related information. At this time, in another perception method provided in the embodiment of the present application, the following step 1101 may be included before step 1102. Fig. 12B ,by Fig. 12A The method shown also includes step 1101 as an example.

[1008] Step 1101: the network side device 1 sends corresponding relationship indication information to the terminal, where the corresponding relationship indication information is used to indicate the corresponding relationship between the first cell related information and the perception related information.

[1009] Correspondingly, after receiving the first cell related information, the terminal can determine the perception related information corresponding to the first cell related information according to the above correspondence, and then in step 1106, the terminal can perceive the second cell according to the perception related information corresponding to the first cell related information.

[1010] The above embodiment takes the example of triggering the terminal to sense the second cell through the first cell related information as an example. In another sensing method provided in the embodiment of the present application, the terminal can be triggered to sense the second cell through a sensing trigger indication sent independently of the above first cell related information. At this time, the following step 1105 can be added between step 1104 and step 1106 in the above embodiment. Fig. 12C ,by Fig.11A Take the method shown in the figure as an example in which the following step 1105 is added between step 1104 and step 1106.

[1011] Step 1105: The network side device 1 sends a first perception trigger indication to the terminal.

[1012] At this time, in step 1106, the terminal can sense the second cell after receiving the first perception trigger indication.

[1013] In an embodiment of the present application, the perception-related information required for perception, such as a perception mode, a perception signal set, a perception signal resource, a configuration of a perception signal, and / or a configuration of a perception report, etc., can be indicated by the perception-related information associated with the first cell-related information, and then the terminal is triggered to perceive the second cell through a first perception trigger indication sent independently of the above-mentioned first cell-related information, so that the perception triggering method is more diverse and flexible.

[1014] It should be noted that as long as the above-mentioned step 1105 is located before step 1106, the execution order of step 1102 and step 1104 is not limited. For example, in other embodiments provided in the present application, the above-mentioned step 1105 can also be located before step 1102, or between step 1102 and step 1104.

[1015] In the above embodiment, the terminal or the core network server may trigger the network side device 2 to sense the second cell. In another embodiment provided by the present application, the second cell related information sent by the network side device 1 to the network side device 2 may trigger the network side device 2 to sense the second cell. At this time, the above embodiment may further include the following step 1201 before step 1106. Fig.12DAs shown, Fig.11A The method shown is exemplified by adding step 1201 before step 1106.

[1016] Step 1201: Network side device 1 sends second cell related information to network side device 2.

[1017] In one instance, if the second cell related information is not associated with the second perception related information, in step 1106, the network side device 2 may cooperate with the terminal to perceive the second cell according to the second perception related information predefined by the protocol or preconfigured by the core network server or the network side device 1.

[1018] In another example, if the second cell-related information is associated with the second perception-related information, the network side device 2 may sense the second cell according to the second perception-related information associated with the second cell-related information in step 1106. The specific implementation of the network side device 2 sensing the second cell according to the perception-related information associated with the second cell-related information may refer to step 701, which is not described in detail here.

[1019] It should be noted that the above step 1201 is executed before step 1106 , and there is no restriction on the execution order of step 1102 and step 1104 .

[1020] Optionally, if the second cell-related information is associated with the perception-related information, the core network server or the network-side device 1 may configure the second perception configuration information for the network-side device 2 before step 1201, so that the network-side device 2 can determine the perception-related information associated with the second cell-related information according to the second perception configuration information. The specific implementation of the second perception configuration information can refer to Fig. 12A The main difference in step 1100 is that the receiving end is replaced by the network side device 2 from the terminal, which will not be described here.

[1021] Optionally, in the embodiment of the present application, when the second cell-related information is associated with the perception-related information, specifically, the second cell-related information has a corresponding relationship with the perception-related information, the core network server or the network-side device 1 can configure the network-side device 2 with corresponding relationship indication information before step 1102 to indicate the corresponding relationship between the second cell-related information and the perception-related information, so that after the network-side device 2 receives the second cell-related information, it can determine the perception-related information corresponding to the second cell-related information according to the above-mentioned corresponding relationship. For specific implementation, please refer to Fig. 12B The main difference in step 1101 is that the receiving end is replaced by the network side device 2 from the terminal, which will not be described here.

[1022] In another embodiment provided by the present application, the network side device 2 may not be triggered by the second cell related information to sense the second cell, but may be triggered by a second sensing trigger indication sent independently of the second cell related information to sense the second cell. In this case, step 1202 may be included before step 1106. Fig.12E As shown, Fig.12D As an example, step 1202 is added before step 1106 of the method shown.

[1023] Step 1202: Network side device 1 sends a second perception trigger indication to network side device 2

[1024] At this time, in step 1106, the network side device 2 can sense the second cell after receiving the second perception trigger indication.

[1025] In an embodiment of the present application, the perception-related information required for perception, such as a perception mode, a perception signal set, a perception signal resource, a configuration of a perception signal, and / or a configuration of a perception report, etc., can be indicated by the perception-related information associated with the second cell-related information, and then the network side device 2 is triggered to sense the second cell through a second perception trigger indication sent independently of the above-mentioned second cell-related information, so that the perception triggering method is more diverse and flexible.

[1026] It should be noted that the above step 1202 only needs to be before step 1106 , and the execution order of step 1102 and step 1104 is not limited.

[1027] In another embodiment provided by the present application, the above embodiment may further include the steps of the terminal determining the perception start time and the network side device 2 determining the perception start time. In this case, the following steps 1203A and 1203B may be added between step 1104 and step 1106 of the above embodiment. Fig.12F ,by Fig.11A Take the method shown as an example where step 1203A and step 1203B are added between step 1104 and step 1106.

[1028] Step 1203A: The terminal determines the start time of perception.

[1029] Step 1203B: The network side device 2 determines the start time of perception.

[1030] If step 1106 passes Fig. 11B In the implementation of S31 to S34 shown in , the starting time of perception determined by the terminal in step 1203A may specifically be the starting time of measuring the perception signal, and the starting time of perception determined by the network side device 2 in step 1203B may specifically be the starting time of sending the perception signal.

[1031] If step 1106 passes Fig. 11C In the implementation of S41 to S43 shown in , the starting time of perception determined by the terminal in step 1203A may specifically be the starting time of sending the perception signal, and the starting time of perception determined by the network side device 2 in step 1203B may specifically be the starting time of measuring the perception signal.

[1032] The implementation of the terminal determining the start time of perception can refer to Figure 5A The corresponding instructions in are not repeated here.

[1033] The implementation of the network side device 2 determining the start time of perception can refer to the corresponding description in step 701, which will not be repeated here.

[1034] It should be noted that step 1203A can be executed between step 1104 and step 1106 , and step 1203B can be executed before step 1106 .

[1035] It should be noted that the method by which the network side device 2 determines the start time of perception and the method by which the terminal determines the start time of perception can be the same or different, as long as the two are synchronized so that the network side device 2 and the terminal can cooperate to complete the perception.

[1036] In a sensing method provided in an embodiment of the present application, by associating a cell update request with a sensing behavior, the terminal can sense the second cell after the first cell sends a cell update request. Figure 13 to Figure 16 An exemplary description is given.

[1037] Fig.13 In the illustrated embodiment of the present application, when the cell update request information sent by the terminal in the first cell includes information of the second cell, the terminal senses the second cell.

[1038] Fig.13 The method shown can be executed by a terminal. Fig.13 As shown, the method may include:

[1039] Step 1301: Sending cell update request information in a first cell;

[1040] Step 1302: If the cell update request information includes information of the second cell, sense the second cell.

[1041] Among them, the cell update request information is used to request a cell update, such as beam update, TCI state switch, cell switch, or cell activation.

[1042] The implementation of the first cell and the second cell in the embodiment of the present application can refer to Figure 5A The corresponding instructions in are not repeated here.

[1043] Optionally, when the terminal senses the second cell in step 1302, the sensing may be performed based on the sensing related information. Figure 5A The main difference is that the cell related information is replaced by the cell update request information, which will not be repeated here.

[1044] Optionally, in this embodiment, the network side device may also send a perception trigger indication to the terminal independently of the perception-related information. At this time, if the terminal cooperates with the network side device 1 to perceive the second cell when the terminal has not switched to the second cell, then the network side device 1 may send the perception trigger indication to the terminal. If the terminal cooperates with the network side device 2 to perceive the second cell after the terminal switches to the second cell, then the network side device 1 may send the perception trigger indication to the terminal before switching to the second cell, or the network side device 2 may send the perception trigger indication to the terminal after switching to the second cell.

[1045] Optionally, the process between step 1301 and step 1302 may further include: receiving cell update response information. Optionally, the cell update response information may be associated with the second perception-related information.

[1046] It should be noted that the information indicated by the first perception-related information and the second perception-related information may be the same or different, and the embodiments of the present application do not limit this. Taking the BFRQ associated with the first perception-related information sent by the terminal to the network side device 1 and the BFRR associated with the second perception-related information sent by the network side device 1 to the terminal as an example, the role of the first perception-related information is to request perception according to the first perception-related information, but the second perception-related information actually indicated by the network side device 1 to the terminal through the BFRR is not necessarily the first perception-related information requested by the terminal.

[1047] It should be noted that if the cell update response information is not associated with the second perception-related information, the terminal in step 1302 can perceive the second cell based on the first perception-related information associated with the cell update request information; if the cell update response information is associated with the second perception-related information, the terminal in step 1302 can preferentially perceive the second cell based on the second perception-related information associated with the cell update response information.

[1048] Optionally, the second perception-related information may indicate at least one of the following: a perception association state, a perception trigger indication, a perception mode, a perception signal set, a perception signal resource, a perception signal configuration, and a perception report configuration. For specific implementation, please refer to Figure 5A The corresponding instructions in are not repeated here.

[1049] The implementation of step 1302 when the cell update request information is associated with the perception related information is exemplarily described as follows: In order to distinguish from the subsequent perception related information, the perception related information associated with the cell update request information is referred to as the first perception related information in the embodiment of the present application.

[1050] In example one, the cell update request information may be a beam update request, and the information of the second cell includes a reference signal indicating a new beam in the beam update request, where the reference signal is a reference signal of the second cell. At this time, if the terminal indicates that the reference signal of the new beam is a reference signal of the second cell in the beam update request sent by the first cell, the cell update request information includes the information of the second cell.

[1051] In this example, if the cell update request information is associated with the first perception-related information, it may specifically be that the beam update request is associated with the first perception-related information.

[1052] The beam update request being associated with the first perception-related information may specifically include: the beam update request including the first perception-related information; or, the reference signal indicating the new beam in the beam update request being associated with the first perception-related information.

[1053] At this time, the cell update response information may be a beam update response, and the beam update response may be associated with the second perception-related information.

[1054] Example 2: The cell update request information may be a cell switching request, and the information of the second cell may be the identifier or index of the target cell in the cell switching request. At this time, if the terminal includes the identifier or index of the target cell in the cell switching request sent by the first cell, the cell update request information includes the information of the second cell.

[1055] Optionally, the cell update request information associated with the first perception related information may specifically be a cell handover request associated with the first perception related information. The cell handover request associated with the first perception related information may include:

[1056] The cell switching request includes the first perception related information; or,

[1057] The cell switching request includes the TCI status, and the TCI status is associated with the first perception related information.

[1058] At this time, the cell update response information may be a cell switching command, and the cell switching command may be associated with the second perception-related information.

[1059] Example three, the cell update request information may be a cell activation request, and the information of the second cell may be the identifier or index of the target cell requested to be activated in the cell activation request. At this time, if the terminal includes the identifier or index of the target cell requested to be activated in the cell activation request sent by the first cell, the cell update request information includes the information of the second cell.

[1060] Optionally, the cell update request information associated with the first perception related information may specifically be a cell activation request associated with the first perception related information. The cell activation request associated with the first perception related information may include:

[1061] The cell activation request includes the first perception related information; or,

[1062] The cell activation request includes a reference signal of a target cell requested to be activated, and the reference signal of the target cell requested to be activated is associated with first perception-related information.

[1063] At this time, the cell update response information may be a cell activation command, and the cell activation command may be associated with the second perception related information.

[1064] The following is an exemplary description of a possible implementation manner in which the terminal senses the second cell in step 1302.

[1065] In the first embodiment, the terminal sensing the second cell in step 1302 may specifically include:

[1066] After sending the cell update request information, after a time interval t4, the second cell is sensed.

[1067] Optionally, the start time of the time interval t4 may be: the effective time of the cell update request information, the sending time of the cell update request information, or the receiving time of the confirmation message of the cell update request information.

[1068] Optionally, when the cell update request information is a beam update request, the starting time of the time interval t4 may be: the time of receiving the beam update response, or the time when the beam update is completed.

[1069] Optionally, when the cell update request information is a cell switching request, the starting time of the time interval t4 may be: the time when the cell switching is completed.

[1070] Optionally, when the cell update request information is a cell activation request, the start time of the time interval t4 may be: the time when the cell activation is completed.

[1071] The implementation of the time interval t4 may refer to the relevant description of the time intervals t1 to t3, which will not be repeated here.

[1072] In the second embodiment, the terminal sensing the second cell in step 1302 may specifically include:

[1073] After sending the cell update request information, the second cell is sensed within the time window a4.

[1074] The implementation of time window a4 may refer to the relevant description of time windows a1 to a3, which will not be described in detail here.

[1075] In a third embodiment, the first embodiment and the second embodiment may be combined. In this case, sensing the second cell in step 1302 may specifically include: after sending the cell update request information, after a time interval t4, sensing the second cell within a time window a4.

[1076] The method for determining the time interval t4 and the method for determining the time window a4 in this example can refer to the above examples and will not be described in detail here.

[1077] In a fourth embodiment, the time interval, time window, etc. in the above example may also be carried by a perception trigger indication. In the above embodiment, the time interval, time window, etc. may be determined according to the time information included in the perception trigger indication, and then perception is performed. Based on the above description, the perception trigger indication may be carried by the first perception related information associated with the cell update request information, or may not be carried in the first perception related information, but may be carried by the second perception related information associated with the cell update response information sent by the network side device 1, or the perception trigger indication may be sent to the terminal before or after sending the cell update response information.

[1078] In the fifth embodiment, the perception trigger indication may also carry other time information to indicate the time for perception to the terminal. Accordingly, in this step, perception may also be performed according to the time information carried by the perception trigger indication and the perception related information.

[1079] In the sixth embodiment, the step of determining the start time of perception may be included before step 1302 .

[1080] Optionally, determining the start time of perception may be implemented in the following manner:

[1081] Determine the sensing start time according to the effective time of the cell update request information; or,

[1082] Determine the sensing start time according to the sending time of the cell update request information; or,

[1083] Determine the sensing start time according to the reception time of the confirmation message of the cell update request information; or,

[1084] When the cell update request information is a beam update request, the sensing start time is determined according to the reception time of the beam update response; or,

[1085] When the cell update request information is a beam update request, the sensing start time is determined according to the time when the beam update is completed; or,

[1086] The cell update request information is in TCI state, and the start time of perception is determined according to the time when the TCI state switching is completed; or,

[1087] When the cell update request information is a cell switching request, the sensing start time is determined according to the time when the cell switching is completed; or,

[1088] When the cell update request information is a cell activation request, the sensing start time is determined according to the time when the cell activation is completed.

[1089] In another embodiment provided by the present application, before step 1301, the following may also be included:

[1090] Receive perception enabling indication information, where the perception enabling indication information indicates that cell update request information is used to trigger perception.

[1091] Fig.13 In the method shown, when the cell update request information sent by the first cell includes information of the second cell, the terminal perceives the second cell, thereby associating the cell update behavior with the perception behavior. By utilizing the association relationship, when the cell update behavior occurs, the perception behavior can be initiated without the need for additional transmission of the signaling required for the perception behavior. Communication-assisted perception is realized in the interawareness integrated system, the perception process is accelerated, the signaling overhead and delay of the perception process are reduced, the terminal's surrounding environment information is obtained in a timely manner, the environmental map on the network side is updated, and the communication performance is improved.

[1092] Fig.14 In the illustrated embodiment of the present application, when the network side device 1 receives in the first cell the cell update request information sent by the terminal including the information of the second cell, the network side device 1 can cooperate with the terminal to complete the perception of the second cell.

[1093] Fig.14 The method shown can be executed by the network side device 1. Fig.14 As shown, the method may include:

[1094] Step 1401: Receive cell update request information in a first cell, where the cell update request information includes information of a second cell.

[1095] Optionally, the cell update request information in this step may be associated with the first perception related information, or may not be associated with the first perception related information.

[1096] The implementation of this step can refer to Fig.13 The main difference between the corresponding descriptions in is that Fig.13 In the example, the terminal sends the cell update request information in the first cell, while in this step, the network side device 1 receives the cell update request information in the first cell.

[1097] When the terminal does not switch from the first cell to the second cell, the network side device 1 may cooperate with the terminal to sense the second cell. At this time, step 1401 may further include: sensing the second cell.

[1098] Optionally, when the network side device 1 senses the second cell, it may sense it according to the perception related information. If the network side device 1 and the terminal obtain the perception related information through negotiation, for example, the cell update request information is associated with the first perception related information, or the cell update response information is associated with the second perception related information, or the network side device 1 sends the perception related information to the terminal in advance, then the network side device 1 may sense the second cell according to the perception related information obtained through negotiation.

[1099] Alternatively, if the network side device 1 and the terminal have not negotiated the perception related information, the network side device 1 may perceive the second cell according to the perception related information predefined by the protocol or configured for the network side device 1 by the core network server.

[1100] It should be noted that when the perception-related information includes multiple pieces of information, the above-mentioned methods can also be combined, as long as the network side device and the terminal can cooperate to complete the perception of the second cell. For example, the perception-related information used by the network side device 1 to perceive the second cell, some of the information items can be pre-defined in the network side device 1 according to the protocol, and some of the information items can be associated with the cell update request information.

[1101] The following is an exemplary description of the implementation of the network side device 1 sensing the second cell.

[1102] In the first embodiment, sensing the second cell may be implemented in the following manner:

[1103] After the first cell receives the cell update request information, it senses the second cell after a time interval t5.

[1104] Optionally, the network side device 1 may configure the time interval t5 for the terminal. At this time, before the network side device 1 senses the second cell, the following steps may be further included:

[1105] Sending time interval configuration information, where the time interval configuration information indicates the length of the time interval.

[1106] Optionally, the starting time of the time interval t5 is: the effective time of the cell update request information, the receiving time of the cell update request information, or the sending time of the confirmation message of the cell update request information.

[1107] Optionally, the cell update request information is a beam update request, and the starting time of the time interval t5 may be the time when the beam update request is received, or the time when the beam update is completed.

[1108] Optionally, when the cell update request information is in TCI state, the starting time of the time interval t5 may be: the time when the TCI state switching is completed.

[1109] Optionally, when the cell update request information is a cell switching request, the starting time of the time interval t5 may be: the time when the cell switching is completed.

[1110] Optionally, when the cell update request information is a cell activation request, the start time of the time interval t5 may be: the time when the cell activation is completed.

[1111] The implementation of the time interval t5 may refer to the relevant description of the time intervals t1 to t4, which will not be repeated here.

[1112] In the second embodiment, sensing the second cell may be implemented in the following manner:

[1113] After the first cell receives the cell update request information, it senses the second cell within the time window a5.

[1114] The implementation of time window a5 may refer to the relevant description of time windows a1 to a4, which will not be repeated here.

[1115] In the third embodiment, the first embodiment and the second embodiment may be combined. In this case, the network side device 1 may sense the second cell in the following manner:

[1116] After the first cell receives the cell update request information, after a time interval t5, the second cell is sensed within a time window a5.

[1117] The method for determining the time interval t5 and the method for determining the time window a5 in this example can refer to the above examples and will not be described in detail here.

[1118] In a fourth embodiment, the time interval, time window, etc. in the above example may also be carried by a perception trigger indication. In the above embodiment, the time interval, time window, etc. may be determined according to the time information included in the perception trigger indication, and then perception is performed. Based on the above description, the perception trigger indication may be carried by the first perception related information associated with the cell update request information, or may not be carried in the first perception related information, but may be carried by the second perception related information associated with the cell update response information sent by the network side device 1, or the perception trigger indication may be sent to the terminal before or after sending the cell update response information.

[1119] In the fifth embodiment, the perception trigger indication may also carry other time information to indicate the time for perception to the terminal. Accordingly, in this step, perception may also be performed according to the time information carried by the perception trigger indication and the perception related information.

[1120] In the sixth embodiment, sensing the second cell may be implemented in the following manner:

[1121] Determine the sensing start time according to the effective time of the cell update request information; or,

[1122] Determine the sensing start time according to the reception time of the cell update request information; or,

[1123] Determine the sensing start time according to the sending time of the confirmation message of the cell update request information; or,

[1124] When the cell update request information is a beam update request, the sensing start time is determined according to the sending time of the beam update response; or,

[1125] When the cell update request information is a beam update request, the sensing start time is determined according to the time when the beam update is completed; or,

[1126] The cell update request information is in TCI state, and the start time of perception is determined according to the time when the TCI state switching is completed; or,

[1127] When the cell update request information is a cell switching request, the sensing start time is determined according to the time when the cell switching is completed; or,

[1128] When the cell update request information is a cell activation request, the sensing start time is determined according to the time when the cell activation is completed.

[1129] Optionally, before step 1401, the following steps may also be included:

[1130] Sending perception enabling indication information, wherein the perception enabling indication information indicates that the cell update request information is used to trigger perception.

[1131] Fig.14 In the method shown, when the cell update request information sent by the first cell includes information of the second cell, the network side device 1 can cooperate with the terminal to enable the terminal to perceive the second cell, thereby associating the cell update behavior with the perception behavior. By utilizing the association relationship, when the cell update behavior occurs, the perception behavior can be started without the need to additionally transmit the signaling required for the perception behavior, thereby realizing communication-assisted perception in the interawareness integrated system, accelerating the perception process, reducing the signaling overhead and delay of the perception process, timely obtaining the terminal's surrounding environment information, updating the network side's environmental map, and improving communication performance.

[1132] In the embodiment of the present application, when the terminal includes information about the second cell in the cell update request information sent by the first cell, the network side device 2 can cooperate with the terminal to complete the perception of the second cell. At this time, the method flow executed by the network side device 2 can refer to Figure 7 , I won’t go into details here.

[1133] The following is based on the above Figure 7 , Fig.13 and Fig.14 The method shown, through Figure 15A to Figure 16 The method of sensing between the network side device 1 and the terminal is exemplified.

[1134] Fig.15A A flow chart of a sensing method provided in an embodiment of the present application is shown as follows: Fig.15A As shown, the method may include:

[1135] Step 1502: The terminal sends a cell update request message to the network side device 1 in the first cell, where the cell update request message includes information of the second cell.

[1136] Step 1504A: The network side device 1 determines that the cell update request information includes information of the second cell.

[1137] Step 1504B: The terminal determines that the cell update request information includes information of the second cell.

[1138] Step 1506: The terminal and network side device 1 sense the second cell.

[1139] The implementation of the above steps 1502 and 1504B can refer to Fig.13 The corresponding instructions in are not repeated here.

[1140] In step 1504A, the network side device 1 determines that the cell update request information includes the information of the second cell. Fig.13The implementation of the terminal determining that the cell-related information includes the information of the second cell is mainly different in that the execution subject is changed from the terminal to the network side device 1, which will not be repeated here.

[1141] The implementation of step 1506 can refer to Fig.13 , Fig.14 As well as the corresponding description in step 806, they are not repeated here.

[1142] The realization of the terminal and the network side device 1 sensing the second cell in different sensing modes can refer to Figure 8B Step 806 and Figure 8C The implementation of step 806 is not described here.

[1143] In another perception method provided in an embodiment of the present application, the network side device 1 configures perception configuration information for the terminal. In this case, the following step 1500 may be included before step 1502 of the above embodiment. Fig. 15B ,by Fig.15A The method shown includes step 1500 before step 1502 as an example.

[1144] Step 1500: The network side device 1 sends perception configuration information to the terminal.

[1145] The implementation of this step can refer to the corresponding description in step 800, which will not be repeated here.

[1146] When the cell update request information in the above embodiment is associated with the first perception related information, specifically, the cell update request information and the first perception related information have a corresponding relationship, the network side device 1 can send corresponding relationship indication information to the terminal to indicate the corresponding relationship between the cell update request information and the first perception related information. At this time, in another perception method provided in the embodiment of the present application, the following step 1501 can also be included before step 1502. Fig. 15C ,by Fig. 15B The method shown also includes step 1501 as an example.

[1147] Step 1501: The network side device 1 sends corresponding relationship indication information to the terminal, where the corresponding relationship indication information is used to indicate the corresponding relationship between the cell update request information and the first perception related information.

[1148] Correspondingly, after the network side device 1 receives the cell update request information, it can determine the first perception-related information corresponding to the cell update request information based on the above-mentioned correspondence, and then in step 1506, the network side device 1 and the terminal can perceive the second cell based on the first perception-related information corresponding to the cell update request information.

[1149] In another sensing method provided in an embodiment of the present application, the network side device 1 and the terminal may be triggered to sense by a sensing trigger indication sent independently of the cell update request information. In this case, the following step 1505 may be added between step 1504 and step 1506 in the above embodiment. Fig.15D ,by Fig.15A Take the method shown in the figure as an example in which the following step 1505 is added between step 1504 and step 1506.

[1150] Step 1505: The network side device 1 sends a perception trigger indication to the terminal.

[1151] In the embodiment of the present application, the network side device 1 and the terminal are triggered to sense the second cell through a perception trigger indication sent independently of the above-mentioned cell-related information, so that the perception triggering method is more diverse and flexible.

[1152] It should be noted that as long as the above-mentioned step 1505 is located before step 1506, the execution order of step 1502, step 1504A, and step 1504B is not limited. For example, in other embodiments provided in the present application, the above-mentioned step 1505 can also be located before step 1502, or between step 1502 and step 1504A (or step 1504B).

[1153] In another embodiment provided by the present application, the step of determining the start time of the perception by the network side device 1 and the terminal may be further included. In this case, the following steps 1601A and 1601B may be added between step 1504 and step 1506 of the above embodiment. Fig.16 ,by Fig.15A Take the method shown as an example where step 1601A and step 1601B are added between step 1504 and step 1506.

[1154] Step 1601A: The network side device 1 determines the start time of perception.

[1155] Step 1601B: The terminal determines the start time of perception.

[1156] The implementation of step 1601A can refer to step 1001A and Fig.14 The corresponding instructions in are not repeated here.

[1157] The implementation of step 1601B can refer to step 1001B and Fig.13 The corresponding instructions in are not repeated here.

[1158] The following is based on the above Figure 7 , Fig.13 and Fig.14 The method shown, through Figures 17A to 19An exemplary description is given of a method in which the network side device 1, the network side device 2 and the terminal cooperate to sense the second cell.

[1159] Fig.17A is a flow chart of a sensing method provided in an embodiment of the present application, such as Fig.17A As shown, the method may include:

[1160] Step 1702: The terminal sends a cell update request message to the network side device 1 in the first cell, where the cell update request message includes information of the second cell.

[1161] Step 1704: The terminal determines that the cell update request information includes information of the second cell.

[1162] Step 1706: The terminal and network side device 2 sense the second cell.

[1163] In one example, the cell update request information sent by the terminal in step 1702 may not be associated with the first perception-related information, then in step 1706 the terminal may perceive the second cell according to the perception-related information predefined in the terminal according to the protocol or preconfigured by the network.

[1164] In another instance, the cell update request information sent by the terminal in step 1702 can be associated with the first perception-related information. Then in step 1706, the terminal can determine the first perception-related information associated with the cell update request information based on the cell update request information, and perceive the second cell based on the first perception-related information associated with the cell update request information.

[1165] In an example, the network side device 2 may sense the second cell according to first perception related information predefined in a protocol or preconfigured by a core network server.

[1166] The implementation of step 1706 in different perception modes can refer to Fig. 11B and Fig. 11C And the corresponding instructions are not repeated here.

[1167] In another perception method provided in an embodiment of the present application, the network side device 1 configures the perception configuration information for the terminal. At this time, the step 1702 of the above embodiment may include a step in which the network side device 1 sends the perception configuration information to the terminal. For specific implementation, please refer to Fig. 15B Step 1500 in is not described here.

[1168] In the above embodiment, when the cell update request information is associated with the first perception related information, specifically when the cell update request information has a corresponding relationship with the first perception related information, the network side device 1 can send corresponding relationship indication information to the terminal to indicate the corresponding relationship between the cell update request information and the first perception related information. At this time, before step 1702, the step of the network side device 1 sending corresponding relationship indication information to the terminal can also be included. The above-mentioned corresponding relationship indication information is used to indicate the corresponding relationship between the cell update request information and the first perception related information. For specific implementation, please refer to Fig. 15C Step 1501 in is not described here.

[1169] In another sensing method provided in an embodiment of the present application, the network side device 1 and the terminal may be triggered to sense by a sensing trigger indication sent independently of the cell update request information. In this case, step 1703 may be included before step 1706. Fig. 17B ,by Fig.17A The method shown adds step 1703 as an example.

[1170] Step 1703: The network side device 1 sends a perception trigger indication to the terminal.

[1171] For specific implementation, please refer to Fig.15D Step 1505 in is not described here.

[1172] In another embodiment provided by the present application, the above embodiment may further include a step in which the network side device 2 and the terminal determine the start time of the perception. At this time, the above Fig.17A The following steps 1705A and 1705B may also be included between step 1704 and step 1706. Fig. 17C ,by Fig.17A For example, the method shown includes steps 1705A and 1705B between step 1704 and step 1706.

[1173] Step 1705A: The terminal determines the start time for sensing.

[1174] Step 1705B: The network side device 2 determines the start time for sensing.

[1175] The implementation of the terminal determining the start time of perception can refer to Fig.13 For the corresponding description in , the network side device 2 determines the start time of perception, which can be referred to Figure 7 The corresponding instructions in are not repeated here.

[1176] In another perception method provided in an embodiment of the present application, perception is triggered by a message sent by a network side device to a terminal during a random access process.

[1177] Fig.18 In the embodiment of the present application shown, when the terminal receives a random access message sent by the network side device of the target cell, the terminal senses the target cell.

[1178] like Fig.18 As shown, the sensing method may include:

[1179] Step 1801: The terminal receives a random access message sent by a network side device of a target cell.

[1180] Step 1802: The terminal senses the target cell.

[1181] The messages exchanged between the network side device and the terminal in the four-step random access process may include, for example, messages (message, msg) 1, msg2, msg3, msg4, etc.; the messages exchanged between the network side device and the terminal in the two-step random access process may include, for example, msgA, msgB, etc. Optionally, the random access message received by the terminal in step 1801 may be a message sent to the terminal by the network side device of the target cell in the random access process, for example, may be: message 2 and / or message 4 in the four-step random access process; or message B in the two-step random access process.

[1182] When the terminal perceives the target cell, it can perceive it according to the perception-related information. The perception-related information can be predefined in the terminal according to the protocol, or sent to the terminal by the core network server or the network-side device, or the perception-related information can be associated with a random access message. When the perception-related information includes multiple pieces of information, two or more of the above-mentioned methods such as predefinition in the terminal according to the protocol, sending on the network side, and associating the perception-related information with a random access message can also be combined, as long as the terminal can obtain the perception-related information for perception. For example, some items of information in the perception-related information can be predefined in the terminal according to the protocol, and some items of information can be associated with a random access message.

[1183] It can be understood that the random access message associated with the perception-related information can be the random access message received in step 1801 for triggering perception, or it can be other random access messages. For example, when the terminal receives message 2 in the random access process in step 1801, it can trigger perception of the target cell. However, the network side device can associate the perception-related information through message 2 and / or message 4 in the random access process, so that the terminal can obtain the perception-related information and perform perception.

[1184] Optionally, if the perception-related information is predefined in the terminal according to the protocol, or is sent to the terminal by the core network server or the network side device, the perception-related information may indicate at least one of the following: a perception trigger indication, a perception mode, a perception signal set, a perception signal resource, a perception signal configuration, and a perception report configuration.

[1185] Optionally, if the random access message is associated with perception-related information, the perception-related information may indicate at least one of the following: a perception association state, a perception trigger indication, a perception mode, a perception signal set, a perception signal resource, a perception signal configuration, and a perception report configuration.

[1186] The realization of perceiving relevant information can refer to Figure 5A The corresponding instructions in are not repeated here.

[1187] In some embodiments, the perception trigger indication may not be carried in the perception related information, but may be sent independently of the perception related information. In this case, the process before step 1802 may also include: receiving the perception trigger indication.

[1188] Optionally, the network side device may configure perception configuration information for the terminal, so that the terminal may determine the perception related information associated with the random access message according to the perception configuration information. In this case, before step 1802, the following may also be included:

[1189] Receive perception configuration information; the perception configuration information includes at least one of the following:

[1190] Candidate perception mode configuration information, candidate perception signal configuration information, candidate perception report configuration information.

[1191] Correspondingly, in step 1802, the terminal can obtain the corresponding configuration from the perception configuration information according to the perception-related information, and perform perception.

[1192] The following is an exemplary description of the implementation of the terminal sensing the target cell.

[1193] In the first embodiment, the terminal may sense the target cell in step 1802 in the following manner:

[1194] After receiving the random access message, after a time interval t6, the target cell is sensed.

[1195] Optionally, the start time of the time interval t6 may be: the validity time of the random access message, the reception time of the random access message, the sending time of the confirmation message of the random access message, or the completion time of the random access.

[1196] The implementation of the time interval t6 may refer to the implementation of the time intervals t1 to t5, which will not be described in detail here.

[1197] In the second embodiment, sensing the target cell in step 1802 may be implemented in the following manner:

[1198] After receiving the random access message, the target cell is sensed within the time window a6.

[1199] The relevant implementation of the time window a4 can refer to the implementation of the aforementioned time windows a1 to a5, which will not be repeated here.

[1200] In a third embodiment, the first embodiment and the second embodiment may be combined. In this case, sensing the target cell in step 1802 may be implemented in the following manner:

[1201] After receiving the random access message, after a time interval t6, the target cell is sensed within the time window a6.

[1202] In a fourth embodiment, the time interval, time window, etc. in the above embodiments may also be carried by a perception trigger indication, and the terminal may determine the above time interval, time window, etc. according to the time information included in the perception trigger indication, and then perceive the second cell. Based on the above description, the perception trigger indication may be carried by a random access message, or may be carried by perception related information associated with the random access message, or may not be carried in the perception related information, but the network side device 1 may send the perception trigger indication to the terminal before or after sending the random access message.

[1203] In the fifth embodiment, the perception trigger indication may also carry other time information to indicate the time for perception to the terminal. Accordingly, the terminal may perceive the second cell according to the time information carried by the perception trigger indication.

[1204] In the sixth embodiment, before step 1802, a step of the terminal determining a start time of perception may be included.

[1205] The terminal can determine the start time of perception in the following ways:

[1207] Determine the sensing start time according to the reception time of the random access message; or,

[1208] Determine the sensing start time according to the sending time of the confirmation message of the random access message; or,

[1209] The sensing start time is determined according to the completion time of the random access.

[1210] In another embodiment provided by the present application, before step 1801, the following may also be included:

[1211] A perception enabling indication information is received, where the perception enabling indication information indicates that a random access message is used to trigger perception.

[1212] The specific implementation of the embodiments of the present application can refer to the corresponding descriptions in the aforementioned embodiments, which will not be repeated here.

[1213] Fig.18 In the method shown, when the terminal receives a random access message from the target cell, it senses the target cell, thereby associating the random access behavior with the perception behavior. By utilizing the association relationship, the perception behavior can be initiated when the random access behavior occurs, without the need to additionally transmit the signaling required for the perception behavior. Communication-assisted perception is implemented in the interawareness integrated system, accelerating the perception process, reducing the signaling overhead and delay of the perception process, timely obtaining the terminal's surrounding environment information, updating the environmental map on the network side, and improving communication performance.

[1214] Fig.19 In the embodiment of the present application shown, when the network side device sends a random access message to the terminal, it cooperates with the terminal to sense the target cell.

[1215] Fig.19 The method shown can be executed by a network side device. Fig.19 As shown, the sensing method may include:

[1216] Step 1901: The network side device sends a random access message to the terminal in the cell of the network side device.

[1217] Step 1902: The network side device senses the cell.

[1219] In the first embodiment, sensing the target cell may be implemented in the following manner:

[1220] After sending the random access message, after a time interval t7, the target cell is sensed.

[1221] Optionally, the start time of the time interval t7 may be: the validity time of the random access message, the sending time of the random access message, the receiving time of the confirmation message of the random access message, or the completion time of the random access.

[1222] The implementation of the time interval t7 may refer to the implementation of the time intervals t1 to t6 described above, which will not be described in detail here.

[1223] In the second embodiment, sensing the target cell may be implemented in the following manner:

[1224] After sending the random access message, the target cell is sensed within the time window a6.

[1225] The implementation of the time window a6 may refer to the implementation of the aforementioned time windows a1 to a5, which will not be described in detail here.

[1226] In a third embodiment, the first embodiment and the second embodiment may be combined. In this case, sensing the target cell may be implemented in the following manner:

[1227] After sending the random access message, after a time interval t6, the target cell is sensed within the time window a6.

[1228] In a fourth embodiment, the time interval, time window, etc. in the above embodiments may also be carried by a perception trigger indication, and the network side device may determine the above time interval, time window, etc. according to the time information included in the perception trigger indication, and then sense the second cell. Based on the above description, the perception trigger indication may be carried by the perception related information associated with the random access message, or may not be carried in the perception related information, but the network side device may send the perception trigger indication to the terminal before or after sending the random access message.

[1229] In the fifth embodiment, the perception trigger indication may also carry other time information to indicate the time for perception to the terminal. Accordingly, the network side device may perceive the second cell according to the time information carried by the perception trigger indication.

[1230] In the sixth embodiment, before sensing the target cell, the step of the network side device determining the start time of sensing may also be included.

[1231] Optionally, the network side device may determine the start time of perception in the following manner:

[1232] Determine the start time of sensing according to the effective time of the random access message; or,

[1233] Determine the sensing start time according to the sending time of the random access message; or,

[1234] Determine the sensing start time according to the reception time of the confirmation message of the random access message; or,

[1235] The sensing start time is determined according to the completion time of the random access.

[1236] In another embodiment provided by the present application, before step 1901, the following may also be included:

[1237] Send perception enabling indication information, where the perception enabling indication information indicates that a random access message is used to trigger perception.

[1238] The specific implementation of the embodiments of the present application can refer to the corresponding descriptions in the aforementioned embodiments, which will not be repeated here.

[1239] Fig.19 In the method shown, after the network side device sends a random access message to the terminal, it cooperates with the terminal to perceive the target cell, thereby associating the random access behavior with the perception behavior. By utilizing the association relationship, when the random access behavior occurs, the perception behavior can be initiated without the need to additionally transmit the signaling required for the perception behavior. Communication-assisted perception is realized in the interawareness integrated system, the perception process is accelerated, the signaling overhead and delay of the perception process are reduced, the terminal surrounding environment information is obtained in a timely manner, the environmental map on the network side is updated, and the communication performance is improved.

[1240] The following is based on the above Fig.18 and Fig.19 The method shown is an exemplary description of the method for sensing between a network-side device and a terminal.

[1241] like Fig. 20 As shown, the method may include:

[1242] Step 2001: The network side device sends a random access message to the terminal.

[1243] Step 2002: The network side device and the terminal sense the cell of the network side device.

[1244] The implementation of the above steps can refer to Fig.18 and Fig.19 The corresponding instructions in are not repeated here.

[1245] In another perception method provided in an embodiment of the present application, perception is triggered by a message sent by the terminal to the network side device during the random access process.

[1246] Fig.21 In the embodiment of the present application shown, after the terminal sends a random access message to the network side device, it senses the target cell.

[1247] like Fig.21 As shown, the sensing method may include:

[1248] Step 2101: The terminal sends a random access message to a network-side device of a target cell.

[1249] Step 2102: The terminal senses the target cell.

[1250] The target cell is a cell that the terminal attempts to access, and the network side device is a network side device of the target cell.

[1251] Optionally, the random access message may be a message sent by the network side device of the target cell to the terminal during the random access process, for example, it may be: message 1 and / or message 3 in the four-step random access process; or message A in the two-step random access process.

[1252] When the terminal perceives the target cell, it can perceive it according to the perception-related information. The perception-related information can be predefined in the terminal according to the protocol, or pre-sent to the terminal by the core network server or the network-side device, or the perception-related information can be associated with a random access message. When the perception-related information includes multiple pieces of information, two or more of the above-mentioned methods such as pre-definition in the terminal according to the protocol, pre-sending by the network-side device, and associating the perception-related information with a random access message can also be combined, as long as the terminal can obtain the perception-related information for perception. For example, some items of information in the perception-related information can be pre-defined in the terminal according to the protocol, and some items of information can be associated with a random access message.

[1253] It can be understood that the random access message associated with perception-related information can be the random access message sent in step 2101 for triggering perception, or it can be other random access messages. For example, when the terminal sends message 1 in the random access process in step 2101, it can trigger perception of the target cell. However, the terminal can indicate the perception-related information to the network side device through message 1 and / or message 3 in the random access process. The network side device can also associate the perception-related information through message 2 and / or message 4 in the random access process, and indicate the perception-related information to the terminal, so that the terminal can obtain the perception-related information and perform perception.

[1254] Optionally, if the perception-related information is predefined in the terminal according to the protocol, or is sent to the terminal in advance by the core network server or the network side device, the perception-related information may indicate at least one of the following: a perception trigger indication, a perception mode, a perception signal set, a perception signal resource, a perception signal configuration, and a perception report configuration.
