[0253] In some embodiments, wireless sensing refers to a wireless signal transmitter emitting radio waves and a wireless signal receiver receiving radio waves. During the transmission of radio waves, the transmission may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and signal intensity change. The wireless signal receiver receives the radio waves and compares the transmitted and received signals, or records the historical changes in the received signal, thereby obtaining information about the reflector. This information about the reflector may include:

[0254] Coordinate information (e.g., coordinates relative to the wireless signal receiver, such as distance, horizontal angle, and vertical angle);

[0255] Speed ​​information (e.g., moving speed and direction of movement relative to the wireless signal receiver);

[0256] Behavioral pattern information (e.g., running, walking, approaching, falling, swinging, etc.; or, weather information such as rain, snow, etc.; or, traffic information such as congestion, accidents, etc.);

[0257] In a wireless network (e.g., a cellular network), the wireless signal transmitter can be at least one of the following: a base station; a wireless access point; or a terminal. The wireless signal receiver can be at least one of the following: a base station; a wireless access point; or a terminal.

[0258] ISAC technology aims to integrate sensing capabilities into the design of communication systems, enabling these systems to provide sensing as a service along with communication to users.

[0259] In some embodiments, Integrated Sensing and Communication (ISCA) technology includes scenario modes such as TRP-TRP bistatic, TRP monostatic, TRP-UE bistatic, UE-TRP bistatic, UE-UE bistatic, and UE monostatic. During the design process, the ISCA system needs to consider both communication and sensing service requirements simultaneously.

[0260] In some embodiments, sensing measurements may include the following modes:

[0261] Mode 1: Base station self-transmitting and self-receiving (i.e., TRPmonostatic). The base station transmits sensing signals, and after the sensing signals pass through the environment or objects in the environment, the base station receives and measures the reflected / scattered waves.

[0262] Mode 2: Base station A transmits and B receives (i.e., TRP-TRP bistatic). Base station A transmits a sensing signal, which passes through the environment or objects in the environment, and base station B receives and measures the reflected / scattered waves.

[0263] Mode 3: Terminal transmits, base station receives (i.e., UE-TRP bistatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the base station receives and measures the reflected / scattered waves.

[0264] Mode 4: Base station transmits, terminal receives (i.e., TRP-UEbistatic). The base station transmits a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave.

[0265] Mode 5: Terminal self-transmission and self-reception (i.e., UEmonostatic). The terminal sends a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the terminal receives and measures the reflected / scattered waves.

[0266] Mode 6: Terminal A transmits, Terminal B receives (i.e., UE-UEbistatic). Terminal A sends a sensing signal, which passes through the environment or objects in the environment, and Terminal B receives and measures the reflected / scattered waves.

[0267] The above six modes can be divided into two categories: the first is monostatic sensing mode, where the same node transmits and receives the sensing RS; the second is bistatic sensing mode, where different nodes, entities, or antenna transceiver units transmit and receive the sensing RS. Monostatic sensing mode can also be called single-node sensing mode, and bistatic sensing mode can also be called dual-node sensing mode.

[0268] In some embodiments, the perceived target (such as a drone) may follow a predetermined planned path, such as a carefully planned flight path, to ensure efficient, standardized and safe operation within a designated airspace.

[0269] To perform tasks such as package delivery, surveillance, or environmental monitoring, commercial drones operate according to pre-defined flight routes that specify their altitude, speed, and direction. For example, a drone delivering goods will follow a direct route from the delivery location to the recipient, while a drone assigned to environmental monitoring will fly from its station to a specific target area to collect data. Route design and optimization are crucial for the safe and efficient operation of drones. These flight routes approved by drone operators prioritize the shortest possible flight path, avoid restricted airspace, and ensure a safe distance from obstacles such as buildings, trees, or other drones. Strict adherence to flight routes minimizes the risk of accidents and improves the reliability of drone services.

[0270] Referring to Figure 1F, in some embodiments, SF can select appropriate sensing signal transmitters and receivers based on the UAV's movement trajectory and measurement results, receive and calculate the sensing results, and schedule sensing nodes to use different sensing modes at different times, for example:

[0271] At time T1, use the TRP1 monostatic mode;

[0272] At time T2, the TRP1-TRP2 bistatic mode is used;

[0273] At time T3, the TRP2 monostatic and TRP2-TRP3 bistatic modes are used.

[0274] In the above embodiments, for UAV trajectory tracking with a known trajectory, controlling the update of the perception mode through SF may bring additional signaling overhead and perception latency.

[0275] In this regard, the present disclosure provides the following embodiments:

[0276] In some embodiments, a sensing coordination process between base stations is introduced, which can be used for target tracking sensing scenarios and for selecting at least one of the sensing transceivers. See the embodiment corresponding to Figure 4C below.

[0277] In some embodiments, two perception control methods are introduced in target tracking perception scenarios:

[0278] Method 1, the cross-base station continuous sensing process with base station assisted control, specifically includes the following methods 1a and 1b:

[0279] In method 1a, the SF determines the RAN nodes participating in sensing, the time and sensing mode corresponding to the participation of each RAN node in sensing, based on the target path. The SF sends the sensing start time and configuration information to the RAN nodes participating in sensing (refer to the sensing time information and mode information introduced in the optional implementation of step S4101 in Figure 4A).

[0280] In method 1b, SF determines the RAN nodes participating in sensing and the service time based on the target path, and the participating RAN nodes manage and control the configuration of sensing modes and sensing signals.

[0281] When the target being sensed moves out of the current RAN's sensing range, the current RAN needs to initiate a sensing measurement or sensing preparation process to the next RAN (see optional implementations of steps S4101, S4104, and S4105 in Figure 4A) and a sensing coordination process (see optional implementations of step S4106 in Figure 4A).

[0282] Method 2 is a cross-base station continuous sensing process controlled by the serving base station, wherein the sensing target is a specific UE.

[0283] The core network sends the context related to the sensing task to the serving RAN of the sensing target. That is, the sensing task is associated with a specific UE. During the handover process, the context related to the sensing task is transmitted as the UE context in the handover request.

[0284] The serving RAN of the sensing target determines the configuration of sensing modes and sensing signals. The serving RAN can coordinate with neighboring base stations to configure appropriate sensing modes and resources.

[0285] In some embodiments, the context of the perceived target includes at least one of the following: SF identifier; perceived task identifier; UE type, used to indicate the target of the perceived task, such as a person, drone, or vehicle; UE path and direction information; serving RAN information and service time information.

[0286] In some embodiments, the content of the sensing and coordination process includes:

[0287] RAN nodes can request other RAN nodes to adjust the configuration of sensing parameters, either through direct signaling instructions or measurement results;

[0288] RAN nodes can request other RAN nodes to perform measurements in order to determine the timing of the sensing transceiver.

[0289] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0290] Step S2101: The first network element sends third information to the first RAN node.

[0291] In some embodiments, the third information is used by the first RAN node to perform sensing measurements of the target. Optionally, the third information is used to instruct the first RAN node to perform sensing measurements at a specific time.

[0292] In some embodiments, the first RAN node performs sensing measurements on the target based on third information. Optionally, the first RAN node performs sensing measurements on the target at the execution time indicated by the third information.

[0293] In some embodiments, the first RAN node receives third information and saves the contents of the third information for current or future sensing measurements. Optionally, the first RAN node sends a feedback message to the first network element regarding the third information, which indicates whether the first RAN node has successfully received the third information and / or successfully stored the contents of the third information.

[0294] In some embodiments, the third information includes at least one of the following:

[0295] Perception task identifier, used to indicate the perception task associated with perception measurement;

[0296] Perceived target type, used to indicate the type of perceived target;

[0297] UE identifier, used to indicate the sensing target, which is UE;

[0298] Perceive the path and direction information of the target;

[0299] Node information, used to indicate the next sensing node for sensing measurement;

[0300] The execution time of the first RAN node for sensing measurements;

[0301] Sensing mode indicator, used to indicate whether the sensing measurement mode is single-station sensing mode or dual-station sensing mode;

[0302] TRP information is used to indicate the TRPs involved in the sensing measurement.

[0303] In some embodiments, the TRP information may be replaced with other information, such as information for indicating multiple antenna elements deployed at different locations under a base station (such as a first RAN node) that participate in the reception and / or transmission of sensing signals.

[0304] In some embodiments, the type of the sensing target may include user equipment with communication capabilities, or it may include general objects without communication capabilities. For example, the sensing target may be a drone, vehicle terminal, mobile phone, or other device with communication capabilities, or it may be a human body, vehicle body, or other general objects without communication capabilities.

[0305] In some embodiments, when the type of the perceived target is not a user equipment, the third information may not include the UE identifier. Optionally, when the type of the perceived target is a UE, the third information may include the UE identifier.

[0306] In some embodiments, the UE identifier is an identifier that uniquely identifies the UE within the network, such as the S-TMSI, GUTI, etc., which uniquely identify the UE within the operator's network.

[0307] In some embodiments, the UE identifier is an identifier that uniquely identifies the UE within the RAN node. Optionally, the UE identifier is only an identifier visible to the RAN, such as the RAN UE ID.

[0308] In some embodiments, the execution time of the first RAN node performing sensing measurements may include one or more of the following: a start time, such as the time when the sensing signal is started to be transmitted or received; an end time, such as the time when the sensing signal is stopped to be transmitted or received; and a duration, such as the time during which the sensing signal is transmitted or received.

[0309] In some embodiments, the execution time may be determined based on at least one of the following: path and direction information of the perceived target; RAN node location; RAN node sensing range; TRP location; TRP sensing range.

[0310] In some embodiments, node information, i.e., the next sensing node for sensing measurement of the sensing target, may be determined based on at least one of the following: path and direction information of the sensing target; RAN node location; sensing range of the RAN node; TRP location; and sensing range of the TRP.

[0311] For example, after determining the path and direction information of the target being sensed, the core network device (such as the first network element) can obtain the location information and sensing range of the RAN node and / or the TRP under the RAN node that has a communication connection with the core network device, and then determine when the target being sensed may enter the sensing range of which RAN node or which TRP, and generate corresponding third information to send to the first RAN node.

[0312] In some embodiments, node information may include the sensing range of the next sensing node. Optionally, a sensing node may refer to a RAN node and / or a TRP used for performing sensing measurements. Optionally, node information may be used to indicate the RAN identifier of the next RAN node, and / or the TRP identifier of the TPR under the next RAN node used to receive or transmit sensing signals.

[0313] In some embodiments, the TRP information may specifically be used to indicate the TRP for transmitting sensing signals and the TRP for receiving sensing signals.

[0314] It should be understood that, in the process of RAN node sensing and measuring the target, the TRP used to transmit the sensing signal and the TRP used to receive the sensing signal in single-station sensing mode can both be the TRP of that RAN node; in dual-station sensing mode, the TRP used to transmit the sensing signal can be the TRP of another RAN node. For example, when dual-station sensing mode is used in the process of first RAN node sensing and measuring the target, the TRP of the first RAN node can receive the sensing signal and the TRP of the second RAN node can transmit the sensing signal.

[0315] In some embodiments, the first network element is used to provide sensing functionality. Optionally, the first network element is a sensing functionality (SF) network element. Optionally, the first network element can be deployed on the core network side or the access network side.

[0316] In some embodiments, after the first RAN node performs sensing measurement on the sensing target at the execution time indicated by the third information, it sends a sensing measurement report to the first network element. The report may include the measurement results of the first RAN node as a sensing signal receiver, that is, the sensing measurement results of the first RAN node on the sensing target.

[0317] In some embodiments, the first network element can not only send third information to the first RAN node, but also send corresponding information to other RAN nodes on the moving path of the sensing target. For example, it can send corresponding information to the next sensing node (such as the second RAN node) of the first RAN node, so that the second RAN node can know the information, execution time, etc. of the next sensing node. In other words, the first RAN node can be any RAN node on the moving trajectory of the sensing target. The first network element can determine the RAN node that needs to perform sensing measurements based on the path and direction information of the sensing target, and determine the time, mode, and other information of each RAN node to perform sensing measurements, and give instructions.

[0318] In some embodiments, the method further includes: the second RAN node receiving eighth information sent by the first network element, the eighth information being used by the second RAN node to perform sensing measurements of the sensing target, the eighth information including at least one of the following:

[0319] Perception task identifier, used to indicate the perception task associated with perception measurement;

[0320] Perceived target type, used to indicate the type of perceived target;

[0321] UE identifier, used to indicate the sensing target, which is UE;

[0322] Perceive the path and direction information of the target;

[0323] Node information, used to indicate the next sensing node for sensing measurement;

[0324] The execution time of the second RAN node for sensing measurements;

[0325] Sensing mode indicator, used to indicate whether the sensing measurement mode is single-station sensing mode or dual-station sensing mode;

[0326] TRP information is used to indicate the TRPs involved in the sensing measurement.

[0327] It is understood that the function of the eighth information in the second RAN node can be the same as the function of the third information in the first RAN node. The optional implementation methods for the association of the eighth information are not described in detail in this disclosure.

[0328] In some embodiments, the first RAN node receives third information sent by the first network element, but is not limited thereto. The first RAN node may also receive third information sent by other network elements, in which case step S2101 is omitted.

[0329] In some embodiments, the first RAN node obtains third information as defined by the protocol, in which case step S2101 is omitted.

[0330] In some embodiments, the first RAN node obtains third information from the upper layer(s), in which case step S2101 is omitted.

[0331] In some embodiments, the first RAN node processes the information to obtain the third information, in which case step S2101 is omitted.

[0332] In some embodiments, the first RAN node autonomously implements the function indicated by the third information, or the above function is a default or default setting. For example, the sensing target type and sensing measurement mode can be defaulted, such as defaulting to user equipment or single-site sensing mode. In this case, the third information may not include the sensing target type and sensing measurement mode.

[0333] In some embodiments, the third information may be referred to as "perception request information", "perception measurement indication", "cooperation information indication", etc., and the present disclosure does not limit its name.

[0334] In step S2102, the first RAN node sends the fourth information to the second RAN node.

[0335] In some embodiments, the second RAN node is the next sensing node after the first RAN node. Optionally, the second RAN node is determined by the first RAN node based on node information indicated by third information.

[0336] In some embodiments, the first RAN node determines that the sensing target has moved into the sensing range of the second RAN node and sends fourth information to the second RAN node.

[0337] In some embodiments, the first RAN node may determine whether the sensed target has moved into the sense range of the second RAN node based on at least one of the following: UE identifier; path and direction information of the sensed target; node information; execution time of the sense measurement; and result of the sense measurement. Optionally, one or more of the UE identifier, path and direction information of the sensed target, node information, and execution time of the sense measurement may be indicated by the third information in step S2101, and the result of the sense measurement may be obtained by the first RAN node performing the sense measurement based on the third information.

[0338] For example, the first RAN node determines the time when it stops sending or receiving sensing signals, and determines that the sensing target has moved into the sensing range of the second RAN node; or, the first RAN node determines, based on the results of sensing measurements, that the sensing target is about to leave its sensing range, and determines that the sensing target has moved into the sensing range of the second RAN node, and so on.

[0339] In some embodiments, the fourth information is used to request the second RAN node to prepare to perform a measurement of the sensing target. Optionally, the fourth information is used to instruct the second RAN stage to prepare to perform a sensing task associated with a sensing measurement of the sensing target.

[0340] In some embodiments, the fourth information includes at least one of the following:

[0341] The first network element identifier is used to indicate the first network element;

[0342] Perception task identifier, used to indicate the perception task associated with perception measurement;

[0346] It is understood that the first network element indicated by the first network element identifier may be the first network element that sends the third information to the first RAN node in step S2101, and this first network element may be referred to as the first network element associated with the sensing measurement of the sensing target.

[0347] In some embodiments, if the second RAN node is the transmitter of the sensing signal, the first configuration information in the fourth information can be omitted.

[0348] In some embodiments, the second RAN node receives a sensing signal sent by the first TRP of the first RAN node according to the first configuration information. Optionally, the second RAN node sends a sensing signal to the first TRP of the first RAN node.

[0349] In some embodiments, after performing sensing measurements, the second RAN node sends the results of the sensing measurements to the first network element based on the identifier of the first network element.

[0350] In some embodiments, the fourth information may be referred to as "sensing preparation information", "sensing configuration instruction", etc., and the present disclosure does not limit its name.

[0351] In step S2103, the second RAN node sends an acknowledgment message for the fourth information to the first RAN node.

[0352] In some embodiments, the confirmation message for the fourth information is used to indicate whether the second RAN node has successfully received the fourth information sent by the first RAN node.

[0353] In some embodiments, the confirmation message of the fourth information is used to indicate whether the second RAN node is ready to complete the sensing measurement of the sensing target.

[0354] In some embodiments, the first RAN node receives an acknowledgment message for the fourth information sent by the second RAN node. Optionally, the first RAN node determines that it has received the acknowledgment message for the fourth information sent by the second RAN node and executes step S2104.

[0355] Step S2104: The first RAN node sends the first information to the second RAN node.

[0356] In some embodiments, the first information is used to request the second RAN node to perform a first operation to coordinate with the first RAN node in performing sensing measurements of the sensing target. Optionally, the first information is used to request the initiation of a sensing coordination process.

[0357] In some embodiments, the sensing measurement of the target includes sensing measurements of the target by at least two RAN nodes. That is, during the sensing measurement of the target, at least two RAN nodes act as receivers of sensing signals, receiving and measuring the sensing signals reflected by the target. For example, the sensing measurement of the target may include at least the sensing measurement of the target by a first RAN node (where the first RAN node acts as a receiver of sensing signals, receiving and measuring the sensing signals) and the sensing measurement of the target by a second RAN node (where the second RAN node acts as a receiver of sensing signals, receiving and measuring the sensing signals).

[0358] In some embodiments, the first information includes at least one of the following:

[0359] User Equipment (UE) identifier is used to indicate the sensing target, which is the UE.

[0360] The first network element identifier is used to indicate the first network element associated with the sensing measurement, and the first network element is used to provide sensing functions;

[0361] Perception task identifier, used to indicate the perception task associated with perception measurement;

[0362] The first measurement report is used to indicate the measurement results of the first RAN node as a receiver of sensing signals;

[0363] The first configuration information is used to instruct the first transmission receiving point (TRP) of the first RAN node to send the first sensing signal.

[0364] Configuration recommendations are provided to assist the second RAN node in adjusting the configuration for sending the second sensing signal to the second TRP, where the second TRP is the TRP of the second RAN node.

[0365] In some embodiments, the measurement results include at least one of the following: Reference Signal Received Power (RSRP); Signal-to-Interference-Ratio (SINR); Line-of-Sight Indication (LOS); and Beam Information.

[0366] In some embodiments, the configuration recommendation may include at least one of the following: a recommended transmission power of the second sensing signal; a recommended transmission beam direction of the second sensing signal.

[0367] It is worth noting that if the RAN node adopts a single-station sensing mode for sensing the target, the RAN node can act as both the sender and receiver of the sensing signal. For example, the first RAN node sends a first sensing signal and receives the first sensing signal reflected by the target, and the second RAN node sends a second sensing signal and receives the second sensing signal reflected by the target.

[0368] If the first RAN node and the second RAN node adopt a dual-station sensing mode for sensing the target, the first RAN node and the second RAN node can act as the sender and receiver of the sensing signal, respectively. For example, the first RAN node sends a first sensing signal, and the second RAN node receives the first sensing signal after it is reflected by the target. The second RAN node sends a second sensing signal, and the first RAN node receives the second sensing signal after it is reflected by the target.

[0369] In some embodiments, at different stages of the sensing measurement of the target, the RAN node can adopt different modes and play different roles in the sensing measurement of the target. For example, in the sensing measurement process of the second RAN node, at a certain stage (such as when the target has just entered the sensing range of the second RAN node), the second RAN node can adopt a bi-station sensing mode, with the first RAN node acting as the transmitter of the sensing signal and the second RAN node acting as the receiver of the target. At another stage (such as when the target leaves the sensing range of the first RAN node but does not leave the sensing range of the second RAN node), the second RAN node can adopt a mono-station sensing mode, with the second RAN node acting as both the transmitter and receiver of the sensing signal.

[0370] In some embodiments, if the first RAN node is a sensing signal transmitter, the first measurement report and the first configuration information can be defaulted. Optionally, if the second RAN node is a sensing signal receiver, the configuration recommendations can be defaulted.

[0371] In some embodiments, the first information may be referred to as "cooperation request information", "cooperation request", "perceived cooperation request message", etc., and the present disclosure does not limit its name.

[0372] In step S2105, the second RAN node performs the first operation based on the first information.

[0373] In some embodiments, the first operation includes at least one of the following: adjusting the transmission power of the second sensing signal; adjusting the transmission beam direction of the second sensing signal; adjusting the receiving beam direction of the first sensing signal; adjusting the receiving beam direction of the second sensing signal; and measuring the second sensing signal, or the first sensing signal.

[0374] In some embodiments, the second RAN node determines what operation needs to be performed based on the first information. For example, if it is determined that the current configuration of the second sensing signal transmitted by the second RAN node is the same as the configuration recommendation, then there is no need to adjust the transmit power, transmit beam direction, and / or receive beam direction of the second sensing signal. If it is determined that the configuration of the second sensing signal transmitted by the second RAN node is different from the configuration recommendation, then the corresponding operation can be performed to obtain the adjusted configuration. As another example, the second RAN node determines whether it needs to adjust the receive beam direction of the first sensing signal based on the first configuration information, and then further receives the first sensing signal and performs measurements.

[0375] For example, if the second RAN node uses a monostation sensing mode for sensing the target, the second RAN node acts as both the transmitter and receiver of the sensing signal. Based on the first information, the second RAN node can adjust one or more of the transmission power, transmission beam direction, and reception beam direction of the second sensing signal. It then receives the adjusted second sensing signal reflected from the target and measures it according to the adjusted reception beam direction to obtain the measurement result. Alternatively, if the second RAN node uses a bistation sensing mode, with the first RAN node as the transmitter and the second RAN node as the receiver, the second RAN node can adjust the reception beam direction of the first sensing signal based on the first information. It then receives the first sensing signal reflected from the target according to the adjusted reception direction and measures it to obtain the measurement result.

[0376] Step S2106: The second RAN node sends the second information to the first RAN node.

[0377] In some embodiments, the second information includes at least one of the following:

[0378] The second measurement report is used to indicate the measurement results of the second RAN node as a receiver of sensing signals;

[0379] The second configuration information is used to indicate the adjusted configuration for the second RAN node to send the second sensing signal.

[0380] In some embodiments, the configuration indicated by the second configuration information may be the configuration obtained after the second RAN node performs the first operation. Optionally, this configuration is used by the second RAN node to send a second sensing signal.

[0381] Optionally, the second configuration information is used to indicate the configuration for the second TRP of the adjusted second RAN node to send the second sensing signal. Optionally, the second RAN node sends the second sensing signal based on the adjusted configuration. Optionally, the second TRP of the second RAN node sends the second sensing signal based on the adjusted configuration.

[0382] In some embodiments, if the second RAN node acts as a sensing signal transmitter, the second measurement report may be a default value. Optionally, if the second RAN node acts as a sensing signal receiver, the second configuration information may be a default value.

[0383] In some embodiments, the second measurement report may be obtained by the second RAN node receiving and measuring the adjusted second sensing signal reflected by the sensing target according to the adjusted receiving beam direction. Optionally, the second measurement report may be obtained by the second RAN node receiving and measuring the first sensing signal reflected by the sensing target according to the adjusted receiving direction.

[0384] In some embodiments, the second information may be referred to as “configuration information”, “cooperation request response”, “perceptive cooperation request response”, etc., and the present disclosure does not limit its name.

[0385] Step S2107: The first RAN node performs the second operation based on the second information.

[0386] In some embodiments, the second operation includes at least one of the following: adjusting the transmission power of the first sensing signal; adjusting the transmission beam direction of the first sensing signal; adjusting the receiving beam direction of the first sensing signal; adjusting the receiving beam direction of the second sensing signal; measuring the first sensing signal, or the second sensing signal; and determining the TRP pair participating in the sensing measurement.

[0387] In some embodiments, the first RAN node determines what operation needs to be performed based on the second information. For example, the first RAN node determines, based on the second configuration information, whether it needs to adjust the receiving beam direction of the second sensing signal, and further receive and measure the second sensing signal.

[0388] For example, in the sensing measurement of the target by the second RAN node, if the first RAN node is the transmitter of the sensing signal and the second RAN node is the receiver of the sensing signal, the first RAN node can adjust one or more of the transmission power and transmission beam direction of the first sensing signal according to the second information. Alternatively, in the sensing measurement of the target by the first RAN node, if the first RAN node adopts a monostation sensing mode, and the first RAN node is both the receiver and transmitter of the sensing signal, the first RAN node can adjust one or more of the transmission power, transmission beam direction, and reception beam direction of the first sensing signal according to the second information, and receive the first sensing signal reflected by the sensing target according to the adjusted reception direction and perform measurement to obtain the measurement result.

[0389] In some embodiments, the first RAN node may further determine the TRP pair participating in the sensing measurement after receiving the second information. Optionally, the TRP pair may include at least one TRP pair participating in the sensing measurement of the second RAN node for the sensing target, that is, the TRP pair may include at least one TRP of the second RAN node that receives the sensing signal. For example, when the second RAN node uses a single-site sensing mode for all measurements of the sensing target, the TRP pair participating in the sensing measurement may include a pair of TRPs of the second RAN node. If the second RAN node uses a dual-site sensing mode and the first RAN node is the transmitter of the sensing signal, the TRP pair participating in the sensing measurement may include one TRP of the first RAN node and one TRP of the second RAN node.

[0390] In some embodiments, after the first RAN node determines the information of the TRP pair participating in the sensing measurement, it can use it itself, for example, to perform sensing measurement based on the TRP pair, or it can report the information to the first network element.

[0391] In step S2108, the second RAN node sends the fifth information to the first RAN node.

[0392] In some embodiments, the fifth information includes at least one of the following: a first network element identifier for indicating a first network element; and a sensing task identifier for indicating a sensing task associated with sensing measurement.

[0393] In some embodiments, the fifth information is used to instruct the first RAN node to stop sensing measurements. Optionally, the fifth information is used to instruct the first RAN node to stop sensing measurements of the sensing target. Optionally, the first RAN node determines the sensing task to be stopped based on the fifth information. Optionally, the fifth information is used to instruct the first RAN node to stop receiving sensing signals. Optionally, the first RAN node uses a single-site sensing mode for sensing measurements of the sensing target, and the fifth information is used to instruct the first RAN node to stop transmitting and receiving sensing signals.

[0394] In some embodiments, the second RAN node determines that the target being sensed has left the sensing range of the first RAN node and sends the fifth information to the first RAN node.

[0395] In some embodiments, the second RAN node determines whether the sensed target has left the sensing range of the first RAN node based on at least one of the following: UE identifier; path and direction information of the sensed target; node information; execution time of the sensing measurement; and result of the sensing measurement. Optionally, one or more of the UE identifier, path and direction information of the sensed target, node information, and execution time of the sensing measurement may be indicated by information sent by the first network element, and the result of the sensing measurement may be obtained by the second RAN node performing the sensing measurement.

[0426] For example, after determining the path and direction information of the sensed target, the core network device (such as the first network element or the second network element) can obtain the location information and communication range of the RAN node and / or the TRP under the RAN node that have a communication connection with the core network device, and then determine when the sensed target may enter the communication range of which RAN node or which TRP and perform cell handover, and generate the corresponding sixth information to send to the first RAN node.

[0427] In some embodiments, the sixth information is used to establish the perceptual context of the perceived target.

[0428] In some embodiments, the second network element is a core network device. Optionally, the second network element is used for access and mobility management. Optionally, the second network element is an Access and Mobility Management Function (AMF) network element.

[0429] In some embodiments, the second network element receives context-related information about the sensing target sent by the first network element, and sends sixth information to the first RAN node based on the context-related information.

[0430] In some embodiments, the first RAN node sends the sixth information by the second network element, but it is not limited to this. The first RAN node may also receive the sixth information sent by other entities, in which case step S2201 is omitted.

[0443] In some embodiments, the second RAN node is the next serving RAN node of the sensing target.

[0444] In some embodiments, the first RAN node determines the second RAN node based on RAN information and / or RAN service time information.

[0445] In some embodiments, after determining the second RAN node based on the RAN information, step S2204 is executed.

[0446] Step S2204: The first RAN node sends the first information to the second RAN node.

[0447] In some embodiments, the first information is used to request the second RAN node to perform a first operation to coordinate with the first RAN node in performing sensing measurements of the sensing target. Optionally, the first information is used to request the initiation of a sensing coordination process.

[0448] In some embodiments, the sensing measurement of the target includes sensing measurements of the target by at least two RAN nodes. That is, during the sensing measurement of the target, at least two RAN nodes act as receivers of sensing signals, receiving and measuring the sensing signals reflected by the target. For example, the sensing measurement of the target may include at least the sensing measurement of the target by a first RAN node (where the first RAN node acts as a receiver of sensing signals, receiving and measuring the sensing signals) and the sensing measurement of the target by a second RAN node (where the second RAN node acts as a receiver of sensing signals, receiving and measuring the sensing signals).

[0449] In some embodiments, the first information includes at least one of the following:

[0450] UE identifier, used to indicate the sensing target, which is UE;

[0451] The first network element identifier is used to indicate the first network element associated with sensing and measurement.

[0452] Perception task identifier, used to indicate the perception task associated with perception measurement;

[0453] The first measurement report is used to indicate the measurement results of the first RAN node as a receiver of sensing signals;

[0454] The first configuration information is used to instruct the first transmission receiving point (TRP) of the first RAN node to send the first sensing signal.

[0455] Configuration recommendations are provided to assist the second RAN node in adjusting the configuration for sending the second sensing signal to the second TRP, where the second TRP is the TRP of the second RAN node.

[0456] In some embodiments, the configuration recommendation may include at least one of the following: a recommended transmission power of the second sensing signal; a recommended transmission beam direction of the second sensing signal.

[0457] It is worth noting that if the RAN node adopts a single-station sensing mode for sensing the target, the RAN node can act as both the sender and receiver of the sensing signal. For example, the first RAN node sends a first sensing signal and receives the first sensing signal reflected by the target, and the second RAN node sends a second sensing signal and receives the second sensing signal reflected by the target.

[0458] If the first RAN node and the second RAN node adopt a dual-station sensing mode for sensing the target, the first RAN node and the second RAN node can act as the sender and receiver of the sensing signal, respectively. For example, the first RAN node sends a first sensing signal, and the second RAN node receives the first sensing signal after it is reflected by the target. The second RAN node sends a second sensing signal, and the first RAN node receives the second sensing signal after it is reflected by the target.

[0459] In some embodiments, at different stages of the sensing measurement of the target, the RAN node can adopt different modes and play different roles in the sensing measurement of the target. For example, in the sensing measurement process of the second RAN node, at a certain stage (such as when the target has just entered the sensing range of the second RAN node), the second RAN node can adopt a bi-station sensing mode, with the first RAN node acting as the transmitter of the sensing signal and the second RAN node acting as the receiver of the target. At another stage (such as when the target leaves the sensing range of the first RAN node but does not leave the sensing range of the second RAN node), the second RAN node can adopt a mono-station sensing mode, with the second RAN node acting as both the transmitter and receiver of the sensing signal.

[0460] In some embodiments, if the first RAN node is a sensing signal transmitter, the first measurement report and the first configuration information can be defaulted. Optionally, if the second RAN node is a sensing signal receiver, the configuration recommendations can be defaulted.

[0461] Step S2205: The second RAN node performs the first operation based on the first information.

[0462] In some embodiments, the first operation includes at least one of the following: adjusting the transmission power of the second sensing signal; adjusting the transmission beam direction of the second sensing signal; adjusting the receiving beam direction of the first sensing signal; adjusting the receiving beam direction of the second sensing signal; and measuring the second sensing signal, or the first sensing signal.

[0463] In some embodiments, the second RAN node determines what operation needs to be performed based on the first information. For example, if it is determined that the current configuration for the second sensing signal is the same as the configuration recommendation, then there is no need to adjust the transmit power, transmit beam direction, and / or receive beam direction of the second sensing signal. As another example, the second RAN node determines whether the receive beam direction of the first sensing signal needs to be adjusted based on the first configuration information, and then receives and measures the first sensing signal.

[0464] For example, if the second RAN node uses a monostation sensing mode for sensing the target, the second RAN node acts as both the transmitter and receiver of the sensing signal. Based on the first information, the second RAN node can adjust one or more of the transmission power, transmission beam direction, and reception beam direction of the second sensing signal. It then receives the adjusted second sensing signal reflected from the target and measures it according to the adjusted reception beam direction to obtain the measurement result. Alternatively, if the second RAN node uses a bistation sensing mode, with the first RAN node as the transmitter and the second RAN node as the receiver, the second RAN node can adjust the reception beam direction of the first sensing signal based on the first information. It then receives the first sensing signal reflected from the target according to the adjusted reception direction and measures it to obtain the measurement result.

[0465] Step S2206: The second RAN node sends the fourth information to the first RAN node.

[0466] In some embodiments, the second information includes at least one of the following:

[0467] The second measurement report is used to indicate the measurement results of the second RAN node as a receiver of sensing signals;

[0468] The second configuration information is used to indicate the adjusted configuration for the second RAN node to send the second sensing signal.

[0469] Optionally, the second configuration information is used to indicate the adjusted configuration for the second TRP under the second RAN node to transmit the second sensing signal. Optionally, the second RAN node transmits the second sensing signal based on the adjusted configuration. Optionally, the second TRP under the second RAN node transmits the second sensing signal based on the adjusted configuration.

[0470] In some embodiments, if the second RAN node acts as a sensing signal transmitter, the second measurement report may be a default value. Optionally, if the second RAN node acts as a sensing signal receiver, the second configuration information may be a default value.

[0471] In some embodiments, the second measurement report may be obtained by the second RAN node receiving and measuring the adjusted second sensing signal reflected by the sensing target according to the adjusted receiving beam direction. Optionally, the second measurement report may be obtained by the second RAN node receiving and measuring the first sensing signal reflected by the sensing target according to the adjusted receiving direction.

[0472] In step S2207, the first RAN node performs the second operation based on the fourth information.

[0473] In some embodiments, the second operation includes at least one of the following: adjusting the transmission power of the first sensing signal; adjusting the transmission beam direction of the first sensing signal; adjusting the receiving beam direction of the first sensing signal; adjusting the receiving beam direction of the second sensing signal; measuring the first sensing signal, or the second sensing signal; and determining the TRP pair participating in the sensing measurement.

[0474] In some embodiments, the first RAN node determines what operation needs to be performed based on the second information. For example, the first RAN node determines, based on the second configuration information, whether it needs to adjust the receiving beam direction of the second sensing signal, and further receive and measure the second sensing signal.

[0475] For example, in the sensing measurement of the target by the second RAN node, if the first RAN node is the transmitter of the sensing signal and the second RAN node is the receiver of the sensing signal, the first RAN node can adjust one or more of the transmission power and transmission beam direction of the first sensing signal according to the second information. Alternatively, in the sensing measurement of the target by the first RAN node, if the first RAN node adopts a monostation sensing mode, and the first RAN node is both the receiver and transmitter of the sensing signal, the first RAN node can adjust one or more of the transmission power, transmission beam direction, and reception beam direction of the first sensing signal according to the second information, and receive the first sensing signal reflected by the sensing target according to the adjusted reception direction and perform measurement to obtain the measurement result.

[0476] In some embodiments, the first RAN node may further determine the TRP pair participating in the sensing measurement after receiving the second information. Optionally, the TRP pair may include at least one TRP pair participating in the sensing measurement of the second RAN node for the sensing target, that is, the TRP pair may include at least one TRP of the second RAN node that receives the sensing signal. For example, when the second RAN node uses a single-site sensing mode for all measurements of the sensing target, the TRP pair participating in the sensing measurement may include a pair of TRPs of the second RAN node. If the second RAN node uses a dual-site sensing mode and the first RAN node is the transmitter of the sensing signal, the TRP pair participating in the sensing measurement may include one TRP of the first RAN node and one TRP of the second RAN node.

[0477] In some embodiments, after the first RAN node determines the information of the TRP pair participating in the sensing measurement, it can use it itself, for example, to perform sensing measurement based on the TRP pair, or it can report the information to the first network element.

[0478] In step S2208, the first RAN node sends a handover request to the second RAN node.

[0479] In some embodiments, the first RAN node sends a handover request to the second RAN node based on RAN service time information.

[0480] In some embodiments, the first RAN node determines that it needs to switch the serving RAN node of the sensed target to the second RAN node and sends a switch request to the second RAN node.

[0481] In some embodiments, the first RAN node determines whether to send a handover request to the second RAN node based on the signal strength of the sensed target (such as RSRP).

[0482] In some embodiments, the handover request is used to switch the serving RAN node of the perceived target to a second RAN node.

[0483] It should be understood that after the serving RAN node of the sensed target switches to the second RAN node (such as leaving the communication range of the first RAN node), the sensed target may still be within the sensing range of the first RAN node.

[0484] In some embodiments, the handover request is used to relay the sixth information to the second RAN node.

[0485] In some embodiments, the switching request includes at least one of the following:

[0486] UE identifier, used to indicate the sensing target;

[0487] The first network element identifier is used to indicate the first network element associated with the sensing measurement, and the first network element is used to provide sensing functions;

[0488] Perception task identifier, used to indicate the perception task associated with perception measurement;

[0489] Perceived target type, used to indicate the type of perceived target;

[0490] Perceive the path and direction information of the target;

[0491] RAN information, used to indicate the next one or more serving RAN nodes for the sensed target;

[0492] RAN service time information is used to indicate the time of service awareness target for each serving RAN node.

[0493] In some embodiments, the second RAN node determines that the service RAN node of the sensed target has completed the handover and sends a handover confirmation to the first RAN node. The handover confirmation is used to indicate that the service RAN node of the sensed target has completed the handover.

[0494] In some embodiments, after the second RAN node determines that the serving RAN node of the sensing target has completed the handover, it performs sensing measurements on the sensing target. Optionally, after the second RAN node determines that the serving RAN node of the sensing target has completed the handover, it measures either the first sensing signal or the second sensing signal.

[0495] In some embodiments, after the second RAN node determines that the serving RAN node of the sensing target has completed its handover, it can send a corresponding request message to the next serving RAN node of the sensing target to request the next serving RAN node of the sensing target to cooperate with the second RAN node in performing sensing measurements for the sensing target. This request message may include, for example, at least one of the following: a UE identifier, used to indicate the sensing target, which is a UE; a first network element identifier, used to indicate the first network element associated with the sensing measurement; a sensing task identifier, used to indicate the sensing task associated with the sensing measurement; the measurement results of the second RAN node as a sensing signal receiver; the configuration of the second RAN node's second TRP for sending a second sensing signal; and a configuration suggestion to assist the next serving RAN node in adjusting the configuration of its sensing signal.

[0496] In some embodiments, after the second RAN node performs sensing measurements on the target, it sends a sensing measurement report to the core network equipment (such as a second network element or a first network element). This report may include the measurement results of the second RAN node as a sensing signal receiver, i.e., the results of the second RAN node's sensing measurements of the target. Optionally, after performing sensing measurements on the target, the second RAN node sends a sensing measurement report to the first network element indicated by the first network element identifier.

[0497] Step S2209: The second RAN node sends the seventh information to the first RAN node.

[0498] In some embodiments, the second RAN node determines that the target has left the sensing range of the first RAN node and sends a seventh message to the first RAN node. Optionally, the seventh message is sent by the second RAN node when it determines that the target has left the sensing range of the first RAN node.

[0499] In some embodiments, the seventh information is used to indicate that the sensing target has left the sensing range of the first RAN node.

[0500] In some embodiments, the seventh information is used to instruct the first RAN node to release the sensing context.

[0501] In some embodiments, after the UE (i.e. the sensing target) switches to the second RAN node, the first RAN node may not release the sensing context of the sensing target so that the first RAN node and the second RAN node can interact with relevant information on sensing coordination until the UE moves out of the sensing range of the first RAN node, at which point the second RAN node may instruct the first RAN node to release the UE context.

[0502] In some embodiments, the seventh information may be referred to as "perception measurement end indication", "task end indication", etc., and the present disclosure does not limit its name.

[0503] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2209. For example, step S2201 may be implemented as an independent embodiment, step S2204 may be implemented as an independent embodiment, step S2208 may be implemented as an independent embodiment, step S2209 may be implemented as an independent embodiment, steps S2204 to S2205 may be implemented as independent embodiments, steps S2204 to S2207 may be implemented as independent embodiments, and steps S2201 to S2204 may be implemented as independent embodiments, but are not limited thereto.

[0504] In some embodiments, steps S2201 to S2203 and steps S2205 to S2208 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0505] In some embodiments, steps S2201 and S2203 to S2208 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0692] In step S4107, the second RAN node and / or the first RAN node perform sensing measurements according to the configuration and report them to the SF.

[0693] In some embodiments, if the sensed target moves to the third RAN node, the second RAN node and the third RAN node may repeat the above steps S4104 to S4106 to negotiate and configure the sensed measurement.

[0694] In step S4108, when the second RAN node determines that the sensing target is not within the coverage area of ​​the first RAN node, the second RAN node sends a sensing measurement end indication to the first RAN node to indicate that the first node can stop the sensing measurement process.

[0695] The end indication of the perception measurement includes at least one of SF ID and perception task identifier.

[0696] Figure 4B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4B, the present disclosure relates to a communication method, which includes:

[0697] In step S4201, CN sends a message to the first RAN node to establish a perception context.

[0698] In some embodiments, the message used to establish the perception context includes a UE identifier and context information of the perception target. The perception target is a specific UE.

[0699] The first RAN node is the serving RAN node of the UE.

[0700] In some embodiments, CN is an AMF, which receives the UE's perception context from the SF.

[0701] In some embodiments, the contextual information of the perceived target includes at least one of the following:

[0702] The SF identifier is used to indicate the management node or sensing result receiving node information of the core network corresponding to the sensing task;

[0703] Perception task identifier, used to identify a specific perception task;

[0704] UE type, used to indicate the target of the perception task, such as a person, drone, or vehicle;

[0705] The path and direction information of the UE is used to indicate the path and direction of the target;

[0706] Information about the serving RAN, used to indicate information about subsequent serving RAN nodes, such as RAN ID (which can be one or more RAN information);

[0707] The RAN service time is used to indicate the time during which each RAN node serves the UE, including, for example, the start time, end time, or duration.

[0708] In some embodiments, the first RAN node can determine the target for UE handover based on the information of the serving RAN and the time of the serving RAN.

[0709] In some embodiments, the first RAN node receives a message for establishing a perception context and establishes the perception context of the UE.

[0710] In step S4202, the first RAN node sends a response to the CN to establish a sensing context.

[0711] In step S4203, the first RAN node performs sensing-related measurements and sends the sensing measurement results to the CN (e.g., SF).

[0712] The perception measurement report includes at least one of the UE identifier and the task identifier.

[0713] Step S4204: The first RAN node and the second RAN node execute a sensing coordination process to coordinate information related to sensing measurement configuration.

[0714] An optional implementation of step S4204 can be found in the embodiment shown in Figure 4C.

[0715] Step S4205: When the UE location changes, the first RAN node sends a handover request message to the second RAN node.

[0716] In some embodiments, the switching request message includes awareness task context information, the specific content of which is as described in step S4201.

[0717] Step S4206: The second RAN node sends a handover request completion message to the first RAN node.

[0718] In step S4207, the second RAN node and / or the first RAN node perform sensing measurements and send the results of the sensing measurements to the CN (such as SF).

[0719] In step S4208, after the UE switches to the second RAN node, the second RAN node can initiate a perception coordination process to other RAN nodes (such as the third RAN node) based on the results of perception measurement and the perception target context information.

[0720] In step S4209, when the second RAN node confirms that the UE has moved into the sensing range of the first RAN node, the second RAN node sends a UE context release instruction to the first RAN node.

[0721] In some embodiments, after the UE switches to the second RAN node, the first RAN node may not release the UE context so that the first RAN node and the second RAN node can interact to sense collaborative information until the UE moves out of the first RAN node's sensing range, at which point the second RAN node may instruct the first RAN node to release the UE context.

[0722] Figure 4C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4C, the embodiments of the present disclosure relate to a communication method, which includes:

[0723] In step S4301, the first RAN node can send a perception coordination request message to the second RAN node.

[0724] In some embodiments, the perception coordination request message is used to request the second RAN node to make adjustments related to perception measurements.

[0725] In some embodiments, the perception coordination process is a signaling process independent of the UE, that is, the perception coordination process is related to the perception task, and the nodes participating in perception or controlling perception are not necessarily the serving base stations of the perception target terminal.

[0726] In some embodiments, the perception coordination process is a signaling process related to the UE, that is, the perception coordination process is specific to a particular UE.

[0727] Optionally, the first perception collaboration request message includes at least one of the following information:

[0729] SF identifier, used to indicate a specific SF;

[0731] The signal configuration suggestion information is used to assist the second RAN node in adjusting the configuration of the transmitted sensing signals, such as increasing the transmission power or adjusting the beam direction.

[0732] The first measurement report is used to indicate the measurement results of the first RAN node as a receiver of sensing signals;

[0733] Sensing signal configuration information is used to instruct the TRP under the first RAN node to send sensing signal configuration.

[0734] In step S4302, the second RAN node receives the perception coordination request message and performs perception-related operations according to the content of the message.

[0735] In some embodiments, the perception-related operations include at least one of the following:

[0736] Adjust the transmission power of the sensing signal;

[0737] Adjust the direction of the transmitted beam of the sensing signal;

[0738] The sensed signal is measured.

[0739] In some embodiments, the method further includes: a second RAN node sending a sensing coordination feedback message to a first RAN node to provide feedback on a sensing coordination request, wherein the message may include at least one of the following information:

[0740] Updated sensing signal configuration information;

[0741] The second measurement report is used to indicate the measurement results of the second RAN node as a sensing signal receiver.

[0747] Report the sensing TRP pair to SF.

[0748] In some embodiments, the first and second measurement reports include at least one of the following information:

[0749] RSRP; SINR; LOS indication; beam information.

[0750] In some embodiments, the first RAN node can determine the TRP-TRP pair based on the sensing coordination feedback message. When there is a sensing requirement, the first RAN node can provide the information of the TRP-TRP pair to the SF to assist the SF in selecting the sensing transmitter and receiver.
