This application embodiment does not limit this.

[0061] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist.

[0065] (I) 5G System Architecture

[0066] Figure 2 illustrates a schematic diagram of a 5G system architecture. A 5G network includes UE (User Equipment) and Access Network (AN) devices, as well as Data Network (DN) and multiple core network elements.

[0067] Network Slice Selection Function (NSSF);

[0068] Authentication Server Function (AUSF);

[0069] Unified Data Management (UDM);

[0070] Access and Mobility Management Function (AMF);

[0071] Session Management Function (SMF);

[0072] Policy Control Function (PCF);

[0073] Application Function (AF);

[0074] User Plane Function (UPF).

[0075] The UE connects to the AN via the Uu interface for access layer communication, exchanging access layer messages and radio data. The UE also connects to the AMF via the N1 interface for non-access layer (NAS) communication, exchanging NAS messages. The AMF is the mobility management function in the core network, and the SMF is the session management function. In addition to managing UE mobility, the AMF is responsible for forwarding session management-related messages between the UE and the SMF. The PCF is the policy management function in the core network, responsible for formulating policies related to UE mobility management, session management, and charging. The UPF is the user plane function in the core network, transmitting data with external data networks via the N6 interface and with the AN via the N3 interface.

[0076] (II) Definition of Wireless Sensing

[0077] In communication-sensing integration (i.e., synergy-sensing integration), sensing capabilities focus on wireless signal perception. This involves analyzing direct, reflected, and scattered radio wave signals to obtain information about the environment and / or target objects within it (such as attributes and states). This enables functions like positioning, ranging, velocity measurement, imaging, detection, recognition, and environmental reconstruction, achieving the perception and exploration of the physical world. Scenarios for synergy-sensing integration include:

[0078] Passive sensing: Sensing nodes (network side or terminal) sense by acquiring electromagnetic waves (such as terahertz waves) emitted by the target object or reflecting electromagnetic waves from outside the sensing node and the target object, such as passive imaging sensing technology in radio astronomy China.

[0079] Active sensing: A sensing sending node (network side or terminal) transmits electromagnetic waves. After being reflected by the target object, the sensing receiving node receives the echo for sensing, such as active radar-like sensing technology that transmits detection signals. In this case, the node receiving the reflected wave is not necessarily the same node that sent the detection signal; that is, multiple sensing nodes can achieve active sensing through some form of joint processing.

[0080] Per-Area / Object Sensing: 5G-A sensing scenarios can be categorized into per-area sensing scenarios and per-object sensing scenarios based on whether the sensing requirements primarily focus on a specified sensing area or a specified sensing target. Sensing needs are prevalent across various industries. Scenarios requiring efficient real-time sensing of the real-time status of roads, vehicles, and people in factories, roads, low-altitude areas, cities, and even larger spatial and temporal ranges are termed per-area sensing scenarios. Scenarios utilizing sensing technology to continuously sense and track objects to obtain dynamic monitoring of their status are termed per-object sensing scenarios.

[0081] Device-based / device-free sensing scenarios can be categorized based on whether the sensed target possesses signal transmission or reception capabilities. For example, in flight path management, base station and terminal beam management, the sensed targets, such as drones and terminals, are user equipment capable of signal transmission or reception, falling under the device-based sensing scenario. In weather monitoring and respiratory monitoring, the sensed targets, such as rainfall and people, are targets without signal transmission or reception capabilities, belonging to the device-free sensing scenario.

[0082] (III) Perception Scenarios and Use Cases

[0083] In intelligent transportation scenarios, integrated communication and sensing base stations or collaboration between base stations enable the perception of the road environment, effectively achieving high-precision map construction and providing beyond-line-of-sight assistance for the safe operation of autonomous vehicles. Integrated communication and sensing base stations or collaboration between base stations enable all-round, all-weather, and uninterrupted detection of the movement trajectory and speed of vehicles, uploading the perceived information to the processing center, comprehensively improving the intelligent perception capability of highway operation status, and providing data support for road supervision. Integrated communication and sensing base stations enable the perception of the railway track environment, achieving all-weather detection of foreign object intrusion around high-speed trains.

[0084] In intelligent low-altitude scenarios, comprehensive and multi-angle perception of the airspace based on integrated communication and sensing base stations or inter-base station collaboration, and providing the perception results to drones, can provide redundancy for obstacle avoidance warnings and improve the success rate of drone obstacle avoidance. Based on integrated communication and sensing base stations or inter-base station collaboration, full airspace perception can be performed to locate and track drones that intrude into the regulatory range, thereby realizing drone intrusion monitoring for fixed areas.

[0085] In smart living scenarios, based on the collaborative working modes of base stations and terminals, or terminals transmitting and receiving data independently, or terminals collaborating with each other, breathing monitoring, fitness monitoring, and gesture / posture recognition are performed by sensing changes in wireless channels. Based on integrated communication and sensing base stations or collaboration between base stations, signal attenuation in the communication link is measured, and then the relationship between signal attenuation and weather indicators is analyzed to obtain the corresponding weather indicators for weather monitoring.

[0086] In smart network scenarios, information such as the density and location of idle terminals within a cell can be obtained based on integrated communication and sensing base stations or through inter-base station collaboration, which can assist in energy saving and optimization of base station resource scheduling within the cell.

[0087] In intelligent transportation scenarios, continuous tracking of vehicles can be achieved based on integrated communication and sensing base stations or cooperation between base stations, enabling real-time dynamic monitoring of vehicle status. For vehicles with wireless communication capabilities, vehicle perception accuracy can be improved through vehicle collaborative sensing.

[0088] In intelligent low-altitude scenarios, drones that intrude into the regulatory range can be located and tracked based on integrated communication and sensing base stations or inter-base station collaboration, and then actions can be taken to drive away "black flight" drones. For networked drones with wireless communication capabilities, drone collaboration can also be used to sense and identify the drone's flight status, obstacles in the flight path, etc., and provide auxiliary flight services.

[0089] In smart living scenarios, by carrying a terminal with communication capabilities, based on the working modes of base station and terminal collaboration, terminal self-transmission and self-reception, or inter-terminal collaboration, a specific human body can be monitored for breathing, fitness, gesture / posture recognition, etc., to achieve accurate real-time dynamic monitoring.

[0090] In intelligent network scenarios, sensing technology can help improve beam management and channel estimation accuracy, enhance the timeliness of terminal beam tracking, improve channel estimation accuracy, and reduce feedback overhead.

[0091] (iv) 3GPP awareness

[0092] Current cellular networks, including 5G networks, are used solely for communication. However, the radio electromagnetic signals used by cellular networks can be used not only for wireless data transmission and communication, but also for environmental sensing capabilities, such as user action or gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, and weather monitoring. Therefore, future cellular networks could be considered not only for communication and data transmission, but also for acquiring sensory information. The table below lists some different levels of sensory information:

[0093] Table 1. Perceptual information at different levels

[0094] Currently, there is discussion about supporting sensing capabilities in B5G networks. This is being achieved by adding a Sensing Function (SF) and corresponding procedures to support sensing functions in 3GPP networks. When an application sends a sensing request for a sensing target to the core network, the core network selects the correct access network device or auxiliary UE (collectively referred to as a sensing node) through the Sensing Function (SF) or AMF, and triggers the ability to perform sensing-related radio measurements, initiating the measurement of sensing information and generating sensing results.

[0095] The main wireless sensing modes of integrated sensing are as follows:

[0096] 1) Base station echo sensing (gNB self-transmitting and self-receiving sensing) as shown in Figure 2A: The base station sends sensing signals and receives echo signals (reflected signals);

[0097] 2) Inter-base station sensing (gNB-2-gNB sensing) as shown in Figure 2B: Base station B receives sensing signals sent by base station A;

[0098] 3) As shown in Figure 2C, air interface uplink sensing (UE-2-gNB sensing): The base station receives sensing signals sent by the terminal;

[0099] 4) As shown in Figure 2D, downlink sensing over the air interface (gNB-2-UE sensing): The terminal receives sensing signals sent by the base station;

[0100] 5) Terminal echo sensing (UE self-transmitting and self-receiving sensing) as shown in Figure 2E: The terminal sends sensing signals and receives echo signals;

[0101] 6) As shown in Figure 2F, the terminal-to-terminal perception (UE-2-UE perception): Terminal B receives the perception signal sent by Terminal A.

[0102] Figures 3 and 4 are flowcharts illustrating two possible control procedures for access network devices or UEs to perform sensing operations. In Figure 3, the sensing request in step 1 is triggered by the AF (Automatic Front-End), hence it is called an AF-triggered sensing procedure. In the AF-triggered sensing procedure, the sensing request is a Mobile Terminated-Sensing Request (MT-SR). In Figure 4, the sensing request in step 1 is triggered by the UE, hence it is called a UE-triggered sensing procedure. The UE requesting the sensing service may be the same as or different from the UE executing the sensing service. In the UE-triggered sensing procedure, the sensing request is a Mobile Originated-Sensing Request (MO-SR). In another possible control procedure, it can be triggered by an internal network element, and the sensing request is a Network Induced-Sensing Request (NI-SR).

[0103] Step 6 in Figure 3 and Step 4 in Figure 4 are the air interface signaling procedures related to perception. The air interface signaling procedures can be divided into the following categories based on the different network elements involved: SF and gNB signaling interaction (gNB-SF), SF and UE signaling interaction (UE-SF), gNB and UE signaling interaction (UE-gNB), and UE and UE signaling interaction (UE-UE). Since different perception modes involve different types of perception nodes (UE / gNB), the required air interface signaling procedures also differ, as shown in the table below:

[0104] Table 2 Air Interface Signaling Procedures Required for Different Sensing Modes

[0105] The following section uses the terminal-aware mode (i.e., UE-2-UE awareness, UE self-transmitting and self-receiving awareness) as an example to introduce the air interface awareness signaling process.

[0106] As shown in Figure 5, for terminal-aware modes (i.e., UE-2-UE awareness, UE self-transmitting and self-receiving awareness), the basic process design needs to consider the different coverage scenarios in which the terminal is located. In the initial design stage, the basic process for terminal-aware modes can prioritize the two main scenarios of in-coverage (IC) and out-of-coverage (OOC).

[0107] In IC scenarios, whether it's UE-to-UE sensing or UE-initiated sensing, SF and other core network elements can participate in the sensing process as control nodes, as shown in Figure 3. Figure 6 is an air interface signaling flowchart for SF-controlled UE-to-UE sensing.

[0108] In OOC scenarios, since the terminal cannot obtain network coverage, core network elements such as SF cannot participate in the terminal sensing process, and the sensing process shown in Figure 3 is not applicable. In this case, it is necessary to select some terminals with strong capabilities to partially undertake some of the tasks of SF in OOC scenarios. Therefore, in addition to the two types of sensing execution terminals, namely sensing sending terminals and sensing receiving terminals, it is also necessary to define the terminal role of sensing service / sensing management terminal (Sensing Server / Management UE).

[0109] Therefore, terminal perception needs to consider the following different terminal roles:

[0110] Sensing Transmitting UE (STx UE): In terminal sensing, it is responsible for transmitting sensing reference signals;

[0111] Sensing Receiving UE (SRx UE): In terminal sensing, it is responsible for receiving the measurement sensing reference signal and obtaining the sensing measurement quantity;

[0112] Sensing Server UE (SS UE) / Sensing Management UE: In terminal sensing, under the OOC scenario, it is a logical node that undertakes some SF functions, such as sensing measurement processing. It may be one of the sensing sending terminal and sensing receiving terminal, or it may be independent.

[0113] Specifically, for UE-initiated sensing, the sensing transmitting terminal and the sensing receiving terminal are the same terminal.

[0114] Figure 7 is a complete flowchart of a UE-autonomous perception service process that only includes the UE, mainly for OOC scenarios or situations where the current network does not support perception services.

[0115] Steps 4-8 are the air interface awareness signaling process. For the air interface process of steps 4-8, Figure 8 further shows a schematic diagram of a UE-autonomous UE-2-UE awareness air interface signaling process, which is mainly for OOC scenarios.

[0116] (v) Positioning scheme based on UE / Location Management Function (LMF)

[0117] Typically, the initiating unit for location services is the terminal NAS layer or the location proxy server, and the terminal, base station, and LMF may play different roles.

[0118] If the location server instructs the terminal to perform location calculation (i.e., UE-based positioning), the terminal completes the location calculation based on the positioning measurement results sent by the network or performed by itself, and sends the calculated location information to the LMF. After verification by the relevant Quality of Service (QoS) of the core network elements, the AMF finally sends the location information to the terminal's NAS layer or proxy server. In other words, UE-based positioning involves the terminal directly calculating the location of the target UE.

[0119] If the location server instructs the LMF to perform the location calculation (i.e., LMF-based positioning), the LMF will use the LPP and NRPPa protocols to aggregate the measurement results of the positioning reference signal from the terminal and TRP respectively and perform the location calculation. Finally, the AMF will forward the location information to the terminal NAS layer or the location proxy server.

[0120] LMF-based positioning includes two types: UE-assisted LMF-based positioning and NG-RAN-node-assisted LMF-based positioning. In UE-assisted LMF-based positioning, the terminal reports the measurement results to the LMF, and the LMF calculates the location of the target UE based on the collected measurement results. In NG-RAN-node-assisted LMF-based positioning, the base station reports the TRP measurement results to the LMF, and the LMF calculates the location of the target UE based on the collected measurement results.

[0121] In some sensing scenarios, sensing nodes or sensing transmitting nodes are in a mobile state. For example, in smart transportation, smart low-altitude, and smart living scenarios, the continuity of sensing services needs to be achieved through cooperation between terminals and base stations when sensing nodes / sensing transmitting nodes are in motion.

[0122] In intelligent transportation scenarios, continuous tracking of vehicles can be achieved based on integrated communication and sensing base stations or cooperation between base stations, enabling real-time dynamic monitoring of vehicle status. For vehicles with wireless communication capabilities, vehicle perception accuracy can be improved through vehicle collaborative sensing.

[0123] In intelligent low-altitude scenarios, drones that intrude into the regulatory range can be located and tracked based on integrated communication and sensing base stations or inter-base station collaboration, and then actions can be taken to drive away "black flight" drones. For networked drones with wireless communication capabilities, drone collaboration can also be used to sense and identify the drone's flight status, obstacles in the flight path, etc., and provide auxiliary flight services.

[0124] In smart living scenarios, by carrying a terminal with communication capabilities, based on the working modes of base station and terminal collaboration, terminal self-transmission and self-reception, or inter-terminal collaboration, a specific human body can be monitored for breathing, fitness, gesture / posture recognition, etc., to achieve accurate real-time dynamic monitoring.

[0125] Furthermore, in the aforementioned sensing scenarios, the sensing information mostly has certain effective range / time limitations. Therefore, how to ensure that sensing nodes send effective and reliable sensing information to each other during mobility is a problem that needs to be solved.

[0126] Figure 9 is a schematic flowchart of an information transmission method performed by a first device according to an embodiment of this application. This method can optionally be applied to the system shown in Figure 1, but is not limited thereto. The method includes at least a portion of the following:

[0127] S910. If the first condition is met, the first device sends first sensing-related information to the second device; wherein the first condition is related to mobility.

[0128] In this embodiment, the device type of the first device may include a terminal or a network device, wherein the network device may include an access network device (e.g., a base station) or a core network device. The device type of the second device may include a terminal or a network device, wherein the network device may include an access network device or a core network device. For example, the first device includes a first terminal, and the second device includes a second terminal, a second access network device, or a core network device. As another example, the first device includes a first access network device, and the second device includes a second terminal, a second access network device, or a core network device.

[0129] As an example, the first device may include a terminal. For instance, the first device includes a terminal that triggers a first condition. This terminal may be a transmitting node or a receiving node for sensing signals. When the terminal triggers the fulfillment of the first condition (e.g., when the terminal is in a mobile state causing cell handover / reselection), the terminal sends first sensing-related information to the second device. Here, the transmitting node for sensing signals can also be called a sensing transmitting node, and the receiving node for sensing signals can also be called a sensing node.

[0130] As an example, the first device may include a network device. For instance, the first device includes a network device serving the cell (source cell) of a terminal that triggers the fulfillment of a first condition. The terminal may be a sensing transmitting node or a sensing node. When the terminal triggers the fulfillment of the first condition, the network device sends first sensing-related information to the second device.

[0131] In this embodiment, the first perception-related information may include any perception-related information obtained by the first device. Optionally, the first perception-related information may include information obtained by the first device through sending and / or receiving perception signals, or through UE reporting, or through network configuration, etc.

[0132] Optionally, the first perception-related information can be perception-related information in any perception scenario / perception mode. For example, the first perception-related information can be perception-related information in smart transportation scenarios, smart low-altitude scenarios, or smart living scenarios. As another example, the first perception-related information can be perception-related information in modes such as base station echo sensing, inter-base station sensing, air interface uplink sensing, air interface downlink sensing, terminal echo sensing, or inter-terminal sensing.

[0133] It should be noted that in this embodiment, the first condition is related to mobility; therefore, satisfying the first condition can also be understood as the occurrence of a mobility-related event or a situation where mobility occurs. According to the above method, when the mobility-related first condition is satisfied, the first device sends first sensing-related information to the second device. In this way, the continuity of sensing services can be ensured based on cooperation between communication devices when mobility occurs at nodes in the sensing scenario.

[0134] Corresponding to the above method, FIG10 is a schematic flowchart of an information transmission method performed by a second device according to an embodiment of the present application, the method including:

[0135] S1010, the second device receives first sensing-related information sent by the first device under the condition that a first condition is met; wherein, the first condition is related to mobility.

[0136] For specific examples and technical effects of the information transmission method performed by the second device in this application embodiment, please refer to the relevant description in the above-described method performed by the first device. For the sake of brevity, it will not be repeated here.

[0137] It should be noted that the method of any embodiment of this application can also be extended and applied to positioning. For example, when a first condition is met, a first device sends first positioning-related information, and correspondingly, a second device receives the first positioning-related information, wherein the first condition is related to mobility. In this way, the continuity of positioning services can be ensured based on cooperation between communication devices even when positioning-related nodes move.

[0138] In some embodiments, the first device includes a first sensing node or a first sensing transmitting node.

[0139] For example, the first device includes a first sensing node, which collects first sensing-related information and reports it to the network device, sensing function node, or sensing management node of the serving cell where the first sensing node is located. When a first condition is met, the first sensing node sends the first sensing-related information to the second device (the network device, sensing function node, or sensing management node of the target cell) to ensure the continuity of the collection of first sensing-related information during mobility.

[0140] For example, the first device includes a first sensing transmission node, which transmits sensing signals based on first sensing-related information. When a first condition is met, the first sensing transmission node transmits the first sensing-related information to the second device to ensure the continuity of related services that transmit sensing signals based on the first sensing-related information.

[0141] In some embodiments, the second device includes a second sensing node, a second sensing transmission node, a sensing function node, or a sensing management node. Optionally, the sensing function node may include a core network element (e.g., SF), a sensing service terminal, or a sensing management terminal. Optionally, the sensing service node may include a core network element (e.g., SF), a sensing service terminal, or a sensing management terminal.

[0142] For example, the second device includes a second sensing node. For instance, the first device includes a first sensing node that collects first sensing-related information. When a first condition is met due to movement of the first device, the first sensing node sends the first sensing-related information to the second sensing node, so that the second sensing node retains continuous first sensing-related information.

[0143] For example, the second device includes a second sensing transmission node. For instance, the first device includes a first sensing transmission node, which transmits sensing signals based on first sensing-related information. When a first condition is met due to movement of the first device, the first sensing transmission node sends the first sensing-related information to the second sensing transmission node, enabling the second sensing transmission node to transmit sensing signals based on the first sensing-related information, thus ensuring continuous transmission of sensing signals and guaranteeing service continuity.

[0144] For example, the second device includes a sensing function node or a sensing management node. The first device collects first sensing-related information or sends sensing signals based on the first sensing-related information. When the first device moves and a first condition is met, the first device sends the first sensing-related information to the sensing function node or the sensing management node so that the sensing function node or the sensing management node can control / manage the sensing process.

[0145] In some embodiments, the first condition includes one or more of the following:

[0146] The first device performs cell handover;

[0147] The first device switches from the idle state (RRC_IDLE) to the connected state (RRC_CONNECTED);

[0148] The first device initiates Radio Resource Control (RRC) connection establishment;

[0149] The first device switches from the inactive state (RRC_INACTIVE) to the connected state;

[0150] The first device initiates RRC connection restoration;

[0151] The first device initiates connection re-establishment;

[0152] The first device performs cell reselection.

[0153] Optionally, the first device may determine that the first condition is met and send the first sensing-related information at the same time as or after the above-mentioned event occurs (e.g., after the handover is completed, or after the connection is successfully established, or while initiating connection recovery).

[0154] For example, the first condition may include the first device performing cell handover. The first device may send first sensing-related information to the second device after the handover is completed. For example, the first sensing-related information may be sent at the same time as sending the RRC reconfiguration completion message or after the RRC reconfiguration completion message is transmitted.

[0155] For example, the first condition may include the first device switching from an idle state to a connected state and / or initiating an RRC connection establishment. After the RRC connection is successfully established, the first device may send first sensing-related information to the second device.

[0156] For example, the first condition may include the first device switching from an inactive state to a connected state and / or initiating an RRC connection recovery. The first device may send first sensing-related information to the second device while initiating the connection recovery.

[0157] It should be noted that the first condition may include only one of the above-mentioned mobility occurrence scenarios, or it may include multiple of the above-mentioned mobility occurrence scenarios. In some embodiments, when the first condition includes multiple scenarios, it can be considered that satisfying any one of the multiple scenarios satisfies the first condition. For example, if the first condition includes the first device performing cell handover, connection re-establishment, and cell reselection, then in all these scenarios, the first device sends first sensing-related information to the second device.

[0158] In some embodiments, the first sensing-related information includes first sensing information and / or first sensing configuration acquired by the first device.

[0159] Optionally, the first perceived information is information acquired based on the perceived signals. In some scenarios, the first perceived information may include relevant information about the perceived target.

[0160] Optionally, the first sensing configuration is used for the first device to send sensing signals.

[0161] In some embodiments, the first sensing information includes sensing information of the first device in the first source node or in the first source state.

[0162] Optionally, the first source node may include the network equipment (including access network equipment, such as source gNB) of the source cell when the first device performs cell handover / reselection. That is, the first sensing information may include the sensing information obtained by the first device in the source cell before performing cell handover / reselection.

[0163] Optionally, the first source state may include the state that the first device was in before performing cell handover, cell reselection, RRC state handover, initiating RRC connection establishment, initiating RRC connection recovery, or initiating connection re-establishment. Optionally, the first source state may include any one of RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED.

[0164] In some embodiments, the first sensing information includes one or more of the following: a sensing signal, a channel response of the sensing signal, a measurement quantity obtained based on the sensing signal, an attribute of the sensing target, and a state of the sensing target.

[0165] Optionally, the first sensing information may include one or more of the sensing information at different levels in the aforementioned related technologies, such as the sensing information shown in Table 1.

[0166] For example, the first sensing information includes the sensing signal, that is, the first sensing information may include one or more of the complex result of the received signal, amplitude, phase, I-channel / Q-channel and related operation results.

[0167] For example, the first sensing information includes the channel response of the sensing signal, that is, the first sensing information may include one or more of the complex result of the channel response, amplitude, phase, I-channel / Q-channel and related operation results.

[0168] For example, the measurement quantities obtained based on the sensed signal may include one or more of time delay, Doppler frequency shift, angle, signal strength, and their multidimensional combined representations.

[0169] For example, the attributes or states of the perceived target may include basic attributes or states of the perceived target, such as one or more of distance, speed, orientation, and acceleration, or advanced attributes or states of the perceived target, such as the presence, spatial location, trajectory, action, expression, vital signs, quantity, imaging results, weather, air quality, shape, material, and composition of the perceived target.

[0170] In practical applications, the first sensing information may include any one or more of the above sensing information. For example, it may include the measurement quantity obtained based on the sensing signal and the state of the sensing target, or the attributes of the sensing signal and the sensing target. The specific information can be determined according to the actual scenario requirements, system conventions or protocol conventions, etc., and will not be listed one by one here.

[0171] In some embodiments, the first sensing configuration includes a reference signal configuration. Optionally, the reference signal configuration may include configuration information such as resource configuration and transmission parameter configuration of the reference signal. Optionally, the reference signal configuration may be an uplink reference signal configuration. Optionally, the reference signal may include a sensing signal.

[0172] In some embodiments, the first sensing configuration may include a reporting configuration. For example, the reporting configuration may be used to configure the content of the first sensing-related information reported by the first device, or information such as reporting time and period. For instance, the reporting configuration may be used to configure the first device to report validity information, time information, or location information when a first condition is met.

[0173] In some embodiments, the first sensing-related information may further include time information and / or location information associated with the first sensing information and / or the first sensing configuration.

[0174] For example, the first sensing-related information includes first sensing information and time information and / or location information associated with the first sensing information; or, the first sensing-related information includes first sensing configuration and time information and / or location information associated with the first sensing configuration; or, the first sensing-related information includes first sensing information, time information and / or location information associated with the first sensing information, first sensing configuration, and time information and / or location information associated with the first sensing configuration. The time information may include a timestamp, and the location information may include a location stamp. In practical applications, the time information and location information can be used to determine whether the first sensing information and / or the first sensing configuration are valid, thereby enabling the second device to determine how to process the received first sensing information and / or the first sensing configuration, which can reduce unnecessary signaling overhead or operations in some scenarios.

[0175] In some embodiments, the first sensing-related information further includes validity information of the first sensing information and / or the first sensing configuration. The validity information, also known as validity status information, indicates whether the first sensing information and / or the first sensing configuration is valid. By transmitting the validity information, the first device enables the second device to determine how to process the received first sensing information and / or the first sensing configuration, which can reduce unnecessary signaling overhead or operations in some scenarios.

[0176] In some embodiments, before the first device sends the first sensing-related information to the second device, the information transmission method may further include: the first device sending second indication information to the second device. Correspondingly, before the second device receives the first sensing-related information sent by the first device under a first condition, the information transmission method further includes: the second device receiving the second indication information from the first device. Optionally, the second indication information may be used to indicate to the second device that the first sensing-related information is about to be transmitted, or the second indication information may be used by the second device to determine whether the first sensing-related information needs to be transmitted.

[0177] In some embodiments, the second indication information includes one or more of the following:

[0178] Does the first device currently have first sensing-related information that needs to be transmitted?

[0179] The validity information of the first perceived relevant information;

[0180] First source node information;

[0181] Perceive business information;

[0182] Perceive target information.

[0183] For example, the second indication information may include whether the first device currently has first perception-related information to be transmitted and the validity of the first perception-related information. When the second indication information indicates that there is first perception-related information to be transmitted and the first perception-related information is valid, the second device may be ready to receive the first perception-related information, or the second device may instruct the first device to transmit the first perception-related information.

[0184] For example, the second indication information may include whether the first device currently has first perception-related information to be transmitted. When the first device currently has first perception-related information to be transmitted, the second indication information may further include perception service information corresponding to the first perception-related information. The second device can determine the service to which the first perception-related information belongs based on the perception service information. Optionally, the perception service information can be used to indicate services in any scenario among intelligent transportation scenarios, intelligent low-altitude scenarios, smart living scenarios, and smart network scenarios, such as vehicle tracking, drone monitoring, and weather monitoring.

[0185] For example, the second indication information may include validity information of the first sensing-related information and first source node information. The validity information indicates whether the first sensing-related information is valid, and the first source node information indicates the first source node or source cell where the first device acquired the first sensing-related information. When the first sensing-related information is valid, the second device may prepare to receive the first sensing-related information, or the second device may instruct the first device to transmit the first sensing-related information, while simultaneously maintaining the information based on the first source node information.

[0186] For example, the second indication information may include sensing target information, which is used by the second device to determine the sensing target, such as a vehicle, drone, environment, weather, etc.

[0187] It is understood that the second indication information may include one or more of the above information. For example, it may only include whether the first device currently has first perception-related information to be transmitted, or only include perception service information. It may also include multiple information such as the validity information of the first perception-related information, the first source node information, and perception service information. The specific information can be determined according to the actual scenario requirements, system agreements, or protocol agreements, etc., and will not be listed here.

[0188] In some embodiments, the second indication information may be carried by UE assistance information, an RRC reconfiguration completion message, an RRC connection establishment completion message, an RRC connection restoration request, or an RRC connection re-establishment completion message. For example, when the first condition includes the first device performing a cell handover, the RRC reconfiguration completion message can be reused to transmit the second indication information. As another example, when the first condition includes the first device switching from an idle state to a connected state and / or initiating an RRC connection establishment, the second indication information may be carried by an RRC connection establishment completion message. As another example, when the first condition includes the first device switching from an inactive state to a connected state and / or initiating an RRC connection restoration, the second indication information may be carried by an RRC connection restoration request. As another example, when the first device initiates a connection re-establishment, the second indication information may be carried by an RRC connection re-establishment completion message. It is understood that the second indication information may also be transmitted by other signaling, such as RRC signaling, Uplink Control Information (UCI), etc. Optionally, these signaling messages may be dedicated to carrying the second indication information or may be signaling multiplexed with other functions. Optionally, the second indication information can also be transmitted independently, that is, without being transmitted through other signaling bearers.

[0189] In some embodiments, the information transmission method further includes: the second device sending a first instruction message or a first request message to the first device; wherein the first instruction message is used to instruct the first device to send first perception-related information to the second device, and the first request message is used to request the first device to send first perception-related information to the second device.

[0190] Accordingly, the first device sending first perception-related information to the second device may include: in response to a first instruction or a first request sent by the second device, the first device sending first perception-related information to the second device.

[0191] Optionally, the first instruction information or the first request information is sent before the first device sends the first sensing-related information. For example, when completing a mobility process, such as upon receiving an RRC reconfiguration completion message or an RRC re-establishment completion message, the second device may send the first request information or the first instruction information to the first device to request or instruct the first device to send the first sensing-related information.

[0192] Optionally, the first indication information or the first request information is sent after the first device sends the second indication information. For example, if the second device receives the second indication information, which indicates that the first device has first sensing-related information to be transmitted, the second device may send the first request information or the first indication information to request or instruct the first device to send the first sensing-related information.

[0193] In some embodiments, the first instruction information or the first request information includes validity condition information for the first perception-related information.

[0194] Optionally, the validity condition information can be used by the first device to assess whether the first perception-related information is valid; in other words, the first device can assess whether the first perception-related information is valid based on the validity condition information. Optionally, in response to the first request information or the first instruction information, the first device can send the first perception-related information if it is valid. Optionally, if the first perception-related information is invalid, the first device can choose not to send the first perception-related information.

[0195] In some embodiments, validity condition information includes valid region information and / or valid time information.

[0196] Optionally, the validity condition information includes valid area information. The first device determines whether the first sensed relevant information is acquired within the valid area based on the valid area information; if it is acquired within the valid area, the first sensed relevant information is valid.

[0197] Optionally, the effective area information can be physical area information, such as information about a circular area, including a reference point and radius indication information, or the effective area information can be area information of other shapes.

[0198] Optionally, the effective area information can be represented by GPS information or at least one cell coverage.

[0199] Optionally, the valid area information may include cell group identifiers. The valid area includes the coverage area of ​​at least one cell. The first device can determine whether it belongs to a valid area by comparing the cell group identifiers in the valid area information with the cell group identifiers of the first sensing related information.

[0200] Optionally, the valid condition information includes valid time information, or the valid condition information includes valid area information and valid time information. The first device determines whether the first sensing-related information was acquired within the valid time based on the valid time information. If it was acquired within the valid time, the first sensing-related information is valid. In practical applications, the content of the valid condition information can be determined according to the actual scenario / business requirements, system agreements, or protocol agreements.

[0201] In some embodiments, the validity condition information may be network-configured, such as via RRC, system messages, or SF configuration. For example, in embodiments where the second device does not send the first indication information or the first request information, or in embodiments where the first indication information or the first request information does not contain validity condition information, the first device may determine whether the first sensing-related information is valid based on other network configuration information.

[0202] In some embodiments, the first device can determine whether the first sensing-related information is valid by comparing the cell group identifiers of the source cell and the target cell.

[0203] In some embodiments, sending first sensing-related information from the first device to the second device may include: the first device sending valid first sensing-related information to the second device. Correspondingly, the second device receiving the first sensing-related information sent by the first device under a first condition includes: the second device receiving the valid first sensing-related information sent by the first device under a first condition.

[0204] For example, the first device sends the first sensing-related information only if the first sensing-related information is valid; that is, by default, only valid first sensing-related information is transmitted. Alternatively, the first device sends the first sensing-related information while simultaneously indicating that the first sensing-related information is valid. Sending valid first sensing-related information avoids unnecessary information transmission overhead.

[0205] In some embodiments, the first sensing-related information may further include one or more of the following: first source node information; sensing service information; sensing target information.

[0206] In some embodiments, the information transmission method may further include: a second device sending second sensing-related information; wherein the second sensing-related information includes a second sensing configuration.

[0207] In some embodiments, the information transmission method may further include: a first device receiving second sensing-related information; wherein the second sensing-related information includes a second sensing configuration. For example, the first sensing-related information includes a first sensing configuration, and the second device may evaluate whether the first sensing configuration is valid and send a second sensing configuration, which is a new configuration, to the first device. Optionally, the second sensing-related information may be sent by other devices. For example, the first device sends the first sensing-related information to a sensing function or a sensing management node, and the sensing function or sensing management node may send the first sensing configuration to a target cell, whereby the target cell determines whether the configuration is valid in the target cell and sends the second sensing configuration to the first device.

[0208] To facilitate understanding of the above technical solutions, several specific application examples are provided below.

[0209] Application Example 1:

[0210] Figure 11 is an interaction flowchart of application example one. This application example takes the first device including UE, the second device including the base station of the target cell (target base station, Target_gNB), and the first perception-related information including perception information as an example. In this example, the UE, as a perception node, sends the UE's perception information in the source cell to the target cell.

[0211] As shown in Figure 11, the information transmission methods include:

[0212] S1.UE, source base station, and SF perform sensing service requests, configurations, and executions based on the sensing service process.

[0213] S2. If the UE is a sensing node, the UE performs sensing based on the sensing configuration and reports the sensing results to the source base station.

[0214] S3. In some scenarios, when the UE is in a mobile state, due to the limited coverage of the source base station, the UE switches to the target cell based on the handover procedure, including when the UE receives a handover command issued by the source base station.

[0215] S4. The UE executes a handover procedure to the target base station based on the handover command, including sending an RRC reconfiguration complete message to the target cell. Optionally, the UE may carry the sensing information to be transmitted in the reconfiguration complete message, or transmit the sensing information to be transmitted simultaneously with the transmission of the RRC reconfiguration complete message, or transmit the sensing information to be transmitted after the transmission of the RRC reconfiguration complete message is completed. Optionally, the UE may carry indication information in the reconfiguration complete message, which is used to indicate to the target cell that the current UE has sensing information to be transmitted. Alternatively, the indication information is used to indicate to the target cell that the current UE has valid sensing information to be transmitted.

[0216] S5. In response to the indication information carried by the UE in the reconfiguration completion message, the target cell may instruct the UE in a subsequent message whether to perform the reporting of perception information, or request the UE to perform the reporting of perception information.

[0217] S6. If the UE is instructed to report the sensing information to be transmitted, the UE shall perform the sensing information reporting.

[0218] In the above process, the UE can evaluate the effectiveness of the perceived information in the following ways:

[0219] Method 1: Based on valid area information, such as the sensing information obtained by the UE being acquired within a valid area. The valid area is network configured, via RRC or system messages. The valid area can be physical area information, such as using a reference point + radius, or other shaped area information, or GPS information, or represented by at least one cell coverage.

[0220] Alternatively, the valid area information can be determined by cell group identifiers, and the valid area includes the coverage area of ​​at least one cell. The UE determines whether it belongs to a valid area by comparing the cell group identifiers to which the sensed information belongs. Alternatively, the UE determines whether the sensed information is valid by comparing the cell group identifiers of the source cell and the target cell.

[0221] Method 2: Based on valid time information, such as the sensing information acquired by the UE being obtained within a valid time period. The valid time period is configured by the network and can be achieved through RRC, system messages, or carried in the handover command. The UE determines the validity of the sensing information by whether it was acquired within the valid time period.

[0222] Validity assessment ensures the usability of transmitted sensing information, avoiding additional signaling overhead caused by unnecessary transmission. For different scenarios, such as map building which relies on regional validity and illegal flight detection which has time-related validity limitations, evaluating the validity of sensing information can make its transmission more efficient.

[0223] Application Example 2:

[0224] Figure 12 is an interaction flowchart for application example two. This application example takes a first device including a UE, a second device including an SF, and a first perception-related information including perception information as an example. In this example, the UE, as a perception node, sends the UE's perception information in the source cell to the SF.

[0225] As shown in Figure 12, the information transmission methods include:

[0226] S1.UE and SF execute perception service requests, configurations, and executions based on perception service processes.

[0227] S2. If the UE is a sensing node, the UE performs sensing based on the sensing configuration and reports the sensing results to the SF through the source base station.

[0228] S3. In some scenarios, when the UE is in a mobile state, due to the limited coverage of the source base station, the UE switches to the target cell based on the handover procedure, including when the UE receives a handover command issued by the source base station.

[0229] S4. The UE executes the handover procedure to the target base station based on the handover command, including sending an RRC reconfiguration completion message to the target cell.

[0230] Optionally, the UE may transmit the sensing information to be transmitted at the same time as the RRC reconfiguration message transmission is completed, or transmit the sensing information to be transmitted after the RRC reconfiguration message transmission is completed.

[0231] S5. Optionally, the UE may first transmit sensing indication information to the SF. This indication information is used to indicate to the SF that the current UE has sensing information to be transmitted, or the indication information is used to indicate to the SF that the current UE has valid sensing information to be transmitted.

[0232] S6. In response to the indication information transmitted by the UE, the SF can instruct the UE in a subsequent message whether to perform the reporting of perception information.

[0233] S7. If the UE is instructed to report the sensing information to be transmitted, the UE shall perform the sensing information reporting.

[0234] In the above process, the UE can evaluate the effectiveness of the perceived information in the following ways:

[0235] Method 1: Based on valid area information, such as the sensing information obtained by the UE being acquired within a valid area. The valid area is network configured, via RRC or system messages. The valid area can be physical area information, such as using a reference point + radius, or other shaped area information, or GPS information, or represented by at least one cell coverage.

[0236] Alternatively, the valid area information can be determined by cell group identifiers, and the valid area includes the coverage area of ​​at least one cell. The UE determines whether it belongs to a valid area by comparing the cell group identifiers to which the sensed information belongs. Alternatively, the UE determines whether the sensed information is valid by comparing the cell group identifiers of the source cell and the target cell.

[0237] Method 2: Based on valid time information, such as the sensing information acquired by the UE being obtained within a valid time period. The valid time period is configured by the network and can be achieved through RRC, system messages, or carried in the handover command. The UE determines the validity of the sensing information by whether it was acquired within the valid time period.

[0238] Validity assessment ensures the usability of transmitted sensing information, avoiding additional signaling overhead caused by unnecessary transmission. For different scenarios, such as map building which relies on regional validity and illegal flight detection which has time-related validity limitations, evaluating the validity of sensing information can make its transmission more efficient.

[0239] Application Example 3:

[0240] Figure 13 is the interaction flowchart of application example three. This application example takes the first device including UE, the second device including SF, and the first perception-related information including perception configuration as an example. In this example, the UE, as the perception sending node, sends the UE's perception configuration in the source cell to the SF after handover, and the SF sends the perception configuration to the new node.

[0241] As shown in Figure 13, the information transmission methods include:

[0242] S1.UE and SF execute perception service requests, configurations, and executions based on perception service processes.

[0243] S2. If the UE acts as a sensing transmission node, the UE performs sensing signal transmission based on the sensing configuration.

[0244] S3. In some scenarios, when the UE is in a mobile state, due to the limited coverage of the source base station, the UE switches to the target cell based on the handover procedure, including when the UE receives a handover command issued by the source base station.

[0245] S4. The UE executes the handover procedure to the target base station based on the handover command, including sending an RRC reconfiguration completion message to the target cell.

[0246] S5. Optionally, the UE may send a handover success indication message to the SF after a successful handover. This indication message is used to indicate to the SF that the current UE is handing over to the new target cell.

[0247] S6. In response to the indication information transmitted by the UE, the SF can indicate the UE's perception configuration to the target cell in a subsequent message, so that the target cell can perform perception services. Optionally, after receiving the perception configuration, the target cell can confirm whether the resources associated with the configuration are valid in the target cell, and send back a confirmation message to the UE or SF confirming that the perception configuration is available.

[0248] S7. Optionally, the target cell or SF can also provide new sensing configurations to the UE for the continuation of sensing services.

[0249] The sensing configuration includes the uplink reference signal configuration, which includes the uplink sensing reference signal configuration.

[0250] Application Example 4:

[0251] Figure 14 is the interaction flowchart of application example four. This application example takes the first device including UE, the second device including target base station, and the first perception-related information including perception configuration as an example. In this example, the UE acts as a perception sending node and sends the perception configuration to the new node after handover.

[0252] As shown in Figure 14, the information transmission methods include:

[0253] S1.UE and SF execute perception service requests, configurations, and executions based on perception service processes.

[0254] S2. If the UE acts as a sensing transmission node, the UE performs sensing signal transmission based on the sensing configuration.
