[0068] For decades, wireless communication and radar sensing (C&S) have been developing in parallel, with limited overlap. They share many commonalities in signal processing algorithms, devices, and to some extent, system architecture. In recent years, the coexistence, cooperation, and joint design of these two systems have attracted increasing attention from researchers.

[0069] Early research extensively explored the coexistence of communication and radar systems, focusing on developing effective interference management techniques to enable two separately deployed systems to operate smoothly without interfering with each other. While radar and communication systems may be located in the same place, or even physically integrated, they transmit two different signals in the time / frequency domain. They cooperate by sharing the same resources to minimize interference when operating simultaneously. Corresponding measures include beamforming, cooperative spectrum sharing, primary and secondary spectrum sharing, and dynamic coexistence. However, effective interference cancellation typically places stringent requirements on node mobility and information exchange between nodes, thus limiting practical improvements in spectral efficiency. Since interference in coexisting systems arises from the transmission of two independent signals, it is natural to ask whether we can simultaneously use a single transmitted signal for both communication and radar sensing. Radar systems often use specially designed waveforms, such as short pulses and chirps, to achieve high-power radiation and simplify receiver processing. However, these waveforms are not essential for radar detection; passive radar or passive sensing, which uses different radio signals as sensing signals, is a good example.

[0070] Machine learning, particularly deep learning, has further enhanced the potential of using non-dedicated radio signals for radar sensing. With these technologies, traditional radar is evolving towards more general wireless sensing. Here, wireless sensing can broadly refer to retrieving information from received radio signals, rather than communication data modulated onto signals at the transmitter. For wireless sensing related to target location, common signal processing methods can be used to estimate dynamic parameters such as target signal reflection delay, angle of arrival (AOA), angle of departure (AOD), and Doppler. For sensing target physical characteristics, this can be achieved by measuring the inherent pattern signals of devices, objects, and living organisms. These two sensing methods can be referred to as sensing parameter estimation and pattern recognition, respectively. In this sense, wireless sensing refers to more general sensing technologies and applications using radio signals.

[0071] Integrated Sensing and Communication (ISAC) has the potential to integrate wireless sensing into large-scale mobile networks, referred to here as Perceptive Mobile Networks (PMNs). PMNs can evolve from current 5G mobile networks and are expected to become ubiquitous wireless sensing networks while providing stable, high-quality mobile communication services. They can be built on top of existing mobile network infrastructure without requiring significant changes to network structure and equipment. This will unlock the full potential of mobile networks and avoid the high infrastructure costs of building new wide-area wireless sensing networks separately. With expanded coverage, the integrated communication and sensing capabilities are expected to enable many new applications. Perceptive Mobile Networks can simultaneously provide communication and wireless sensing services, and due to their large broadband coverage and robust infrastructure, they have the potential to become a ubiquitous wireless sensing solution. Their coordinated communication and sensing capabilities will improve the productivity of our society and help foster a large number of new applications that existing sensor networks cannot effectively realize. Some early work on passive sensing using mobile signals has already demonstrated its potential. Examples include traffic monitoring, weather forecasting, and rainfall remote sensing based on Global System for Mobile Communications (GSM) radio signals. Sensing mobile networks can be widely applied to communication and sensing in transportation, communication, energy, precision agriculture, and security sectors, where existing solutions are either infeasible or inefficient. It can also provide complementary sensing capabilities to existing sensor networks, featuring unique day / night operation and the ability to penetrate fog, foliage, and even solid objects. Some common sensing services are shown in Table 1 below:

[0072] Table 1

[0073]

[0074] Base stations in mobile communication networks (including one or more Transmission Reception Points (TRPs) on the base station) and User Equipment (UEs) (including one or more antenna subarrays / panels on the UE) can serve as sensing nodes participating in integrated sensing / communication services. By sending and receiving sensing signals through sensing nodes, sensing of a certain area or a certain physical target can be achieved. The sensing signals can be signals that do not contain transmission information, such as existing LTE / NR synchronization and reference signals (including: synchronization signal and physical broadcast channel (PBCH block, SSB) signals, channel state information (CSI) reference signals (CSI-RS), demodulation reference signals (DMRS), sounding reference signals (SRS), positioning reference signals (PRS), phase-tracking reference signals (PTRS), etc.), or single-frequency continuous waves commonly used in radar. Continuous Wave (CW), Frequency Modulated CW (FMCW), and Ultra-Wideband Gaussian Pulse, etc. In addition, the sensing signal can also be a newly designed dedicated sensing signal with good correlation characteristics and a low peak-to-average power ratio (PAPR), or a newly designed integrated sensing signal that carries certain information and has good sensing performance. The type of sensing signal is not specifically limited here, and for ease of explanation, the above signals will be uniformly referred to as the first signal in the following embodiments.

[0075] In this embodiment, the sensing method is divided into a first sensing method and a second sensing method based on whether the sending node and receiving node of the sensing signal are the same device. In the first sensing method, sensing node A sends a first signal and sensing node B receives the first signal. Sensing node A and sensing node B are not the same device and are physically separated. In the second sensing method, the same sensing node sends and receives the first signal on its own. That is, the sending and receiving of the sensing signal is performed by the same device. The sensing node performs sensing by receiving the echo of the signal it sends.

[0076] In related technologies, a single sensing method is typically used to measure the same target. However, in this embodiment, during the process of a sensing node measuring a target using a first sensing method, a switch measurement report can be used to determine whether to switch the sensing method from the first to the second. This allows the sensing results under the first method to fail to meet the performance requirements of the target if changes in the sensing environment, the state of the sensing node, or the state of the target cause these changes. In such cases, the sensing method can be switched to the second method, thereby improving the target's sensing performance.

[0077] The following description, in conjunction with the accompanying drawings, details the sensing mode switching method, sensing mode switching device, terminal, and network-side equipment provided in this application through some embodiments and application scenarios.

[0078] Please see Figure 2 The present application provides a sensing mode switching method, the execution subject of which may be a first node. The first node may include at least one of a core network (such as a sensing network function / sensing network element in the core network), a source base station, and a source access base station. The source base station may be a base station that performs sensing operations on the sensing target according to the first sensing mode before switching sensing modes. The source access base station may be a base station accessed by a UE that performs sensing operations on the sensing target according to the first sensing mode before switching sensing modes. Of course, the above-mentioned first node may also be a UE participating in sensing services, which is not specifically limited here.

[0079] like Figure 2 As shown, a sensing mode switching method provided in this application embodiment may include the following steps:

[0080] Step 201: The first node determines whether to switch the perception mode of the perceived target from the first perception mode to the second perception mode based on the switching measurement report.

[0081] The switching measurement report includes measurement results for determining the switching sensing mode, wherein the signal transmitting node and the signal receiving node of the first sensing mode are different nodes, and the signal transmitting node and the signal receiving node of the second sensing mode are the same node.

[0082] In this context, before switching sensing methods, the node sensing the target using the first sensing method can be called the source sensing node (e.g., source base station or source UE). For further distinction, the node in the source sensing node that transmits the sensing signal can be called the first sensing node, and the node in the source sensing node that receives the sensing signal can be called the second sensing node. The sensing operation under the first sensing method is referred to as first sensing. In implementation, before switching sensing methods, the first sensing node transmits a sensing signal. This signal is reflected by the target and received by the second sensing node. The second sensing node performs sensing measurements on the received signal to obtain the measured values ​​of sensing quantities (e.g., received signal power, angle of arrival, or angle of departure). Based on these measured values, the final sensing result can be determined. For example: Figure 3a As shown, the first sensing node is node A, the second sensing node is node B, the core network device is the first device, and the sensing target is the vehicle.

[0083] In contrast to the source sensing node, the node that senses the target according to the second sensing method after switching sensing methods can be called the target sensing node (e.g., target base station or target UE), and the sensing operation under the second sensing method is called second sensing. In implementation, after completing the sensing method switch, the target sensing node automatically transmits and receives sensing signals, thereby obtaining the measured value of the sensed quantity based on the echo signal reflected by the sensed target. For example: Figure 3b As shown, the target sensing node can be any one of node A, node B, and node C. Node A is the source signal transmitting node before the sensing mode is switched, node B is the source signal receiving node before the sensing mode is switched, and node C can be any node other than node A and node B.

[0084] In one implementation, the target sensing node may be different from the first sensing node and the second sensing node. In another implementation, the target sensing node may be one of the first sensing node and the second sensing node.

[0085] For example Figure 4 Taking the various scenarios of vehicle perception shown as examples, the first perception method can be specifically divided into the following three scenarios:

[0086] In scenario (a), the first sensing method is: uplink sensing between the base station and the UE (i.e., the UE sends a first signal and the base station A receives the first signal) or downlink sensing (i.e., the base station A sends a first signal and the UE receives the first signal).

[0087] In scenario (b), the first sensing method is: sensing between two base stations (e.g., base station A sends a first signal and base station B receives the first signal, or base station B sends a first signal and base station A receives the first signal). Base station B receives the sensing signal.

[0088] In scenario (c), the first sensing method is: sensing between two UEs (e.g., UE A sends a first signal and UE B receives the first signal, or UE B sends a first signal and UE A receives the first signal).

[0089] like Figure 4 As shown, the second sensing method can be specifically divided into the following two scenarios:

[0090] In scenario (d), the second sensing method is: sensing by the base station itself. The base station can be the source base station (base station A or base station B) participating in the first sensing method, or it can be another base station C.

[0091] In scenario (e), the second sensing method is: sensing initiated and received by the UE itself. The UE can be the source base station (UE A or UE B) participating in the first sensing method, or it can be another UE C.

[0092] Depend on Figure 4 It can be seen that, considering the possible changes in the sensing nodes in the network before and after the handover, and that the sensing node after the handover may be a base station or a UE, there are 6 combinations for the above-mentioned switching from the first sensing method to the second sensing method, specifically including:

[0093] 1) The first sensing performed by the base station and UE is switched to the second sensing performed by the base station;

[0094] 2) The first sensing performed by the base station is switched to the second sensing performed by the base station;

[0095] 3) The first sensing operation performed by the base station and UE is switched to the second sensing operation performed by the UE;

[0096] 4) The UE-UE performs the first sensing function, then switches to the UE performing the second sensing function;

[0097] 5) The UE-UE performs the first sensing operation, which is then switched to the base station performing the second sensing operation;

[0098] 6) The first sensing performed by the base station is switched to the second sensing performed by the UE.

[0099] In this implementation, the switching measurement report may include measurement results used to determine whether a switching of the sensing mode is necessary. That is, the switching measurement report may at least include the measured values ​​of the sensing measurements required for the switching measurement. In practice, the sensing measurements required for the switching measurement may include the sensing measurements of the current sensing service; that is, the sensing measurements required for the switching measurement may be the measured values ​​obtained by the sensing nodes that performed sensing measurements on the sensing target according to the first sensing mode before the switching of the sensing mode.

[0100] Optionally, the switching measurement report includes at least one of the following:

[0101] At least one measured value of a sensed quantity;

[0102] Measurement results of at least one perceived performance evaluation indicator;

[0103] The measured value of at least one communication measurement quantity of the signal transmitting node and / or signal receiving node under the first sensing method;

[0104] The measurement results of at least one communication performance evaluation index of the signal transmitting node and / or signal receiving node under the first sensing method;

[0105] Indication information used to indicate whether a preset event has occurred, wherein the preset event is used to trigger a switch in the perception mode of the perceived target from the first perception mode to the second perception mode;

[0106] Indication information used to indicate whether preset switching conditions are met, wherein the preset switching conditions are used to trigger the switching of the perception mode of the perceived target from the first perception mode to the second perception mode.

[0107] Option 1: The measurement value of at least one sensing measurement quantity can be the measurement value of all or part of the sensing measurement quantities obtained by the source sensing node performing the first sensing of the sensing target before the switch. Based on the measurement value, the state change of the sensing target or sensing environment can be reflected, thereby determining whether it is necessary to switch the sensing mode to the second sensing mode. Here, the first sensing means the sensing under the first sensing mode.

[0108] Option 2: The measurement result of at least one perception performance evaluation index can be used to evaluate the perception performance of the perception result after the first perception of the perception target is obtained. The perception performance evaluation result can reflect the quality of the perception performance obtained from the first perception of the perception target. In this way, when the perception performance is poor, the second perception mode can be switched.

[0109] In some embodiments, the perceived performance evaluation metric may include at least one of the following:

[0110] Sensing SNR represents the ratio of the energy of the sensed signal reflected from the sensed target or sensed area to the energy of the noise signal in the environment and equipment.

[0111] Sensing SINR represents the ratio of the energy of the sensed signal reflected from the sensed target or sensed area to the sum of the energy of interference signals and noise signals in the environment and equipment.

[0112] The statistical mean, standard deviation, or variance of multiple measurements of the same perceptual quantity;

[0113] The deviation between the measured value or predicted value of the sensing result and the actual measured value of the sensing quantity, and the statistical mean, standard deviation or variance of the deviation;

[0114] Perception can reuse existing evaluation metrics (such as the sum of Euclidean distances between samples of two consecutive sequences, or the regularized path distance in Dynamic Time Warping (DTW), or other metrics that can reflect the similarity between two sequences). Other metrics that can reflect the similarity between two sequences include, but are not limited to: Longest Common Subsequence (LCSS), Edit Distance on Real Sequences (EDR), Edit Distance with Real Penalty (ERP), Hausdorff Distance, Fréchet Distance, One Way Distance (OWD), and Locality In-between Polylines (LIP).

[0115] Option 3: The measured value of at least one communication measurement of the signal transmitting node and / or signal receiving node under the first sensing method. In implementation, the above-mentioned communication measurement can be Reference Signal Received Power (RSRP), Signal Noise Ratio (SNR), Signal to Interference plus Noise Ratio (SINR), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), Bit Error Rate, Block Error Rate, Throughput, Spectral Efficiency, etc. The measured value based on this communication measurement can reflect the communication performance of the source signal transmitting node and / or source signal receiving node. In this way, when the communication performance of the source signal transmitting node and / or source signal receiving node is poor, the second sensing method can be switched.

[0116] Option 4: If the measurement results of at least one communication performance evaluation index of the signal transmitting node and / or signal receiving node under the first sensing method are similar to the aforementioned sensing performance evaluation index, the communication performance of the source signal transmitting node and / or source signal receiving node can be evaluated based on the communication performance evaluation index. Based on the communication performance evaluation result, the quality of the communication performance of the source signal transmitting node and / or source signal receiving node can be reflected. In this way, when the communication performance of the source signal transmitting node and / or source signal receiving node is poor, the second sensing method can be switched.

[0117] Option 5 is an indication message used to indicate whether a preset event has occurred. The preset event is used to trigger a switch in the perception mode of the perceived target from the first perception mode to the second perception mode.

[0118] In implementation, the aforementioned preset events may include at least one of the following:

[0119] The state of the sensed target changes (e.g., the position or speed of the sensed target changes).

[0120] The position of the first sensing node changes, and the first sensing node is the signal transmitting node under the first sensing method (e.g., the distance between the first sensing node and the sensing target exceeds the maximum sensing distance, or the first sensing node moves to outside the communication range of the second sensing node, etc.).

[0121] The position of the second sensing node changes (e.g., the distance between the second sensing node and the sensing target exceeds the maximum sensing distance, or the second sensing node moves outside the communication range of the first sensing node).

[0122] The environment of the sensing area where the sensing target is located changes (e.g., the density of sensing targets in the sensing area, the weather, etc. change);

[0123] The sensing resources available to the first sensing node have changed (e.g., the channel resources, antennas, and other sensing resources that the first sensing node can use for sensing services have changed).

[0124] The sensing resources available to the second sensing node have changed (e.g., the channel resources, antennas, and other sensing resources that the second sensing node can use for sensing services have changed).

[0125] The measured value of the sensing measurement acquired by the second sensing node reaches the first preset threshold (e.g., at least one of the sensing signal receiving power, sensing SNR, sensing SINR, distance / velocity / angle measurement value, etc. meets the preset switching threshold value).

[0126] The measurement value of the communication measurement acquired by the second sensing node or the measurement value of the communication measurement between the second sensing node and the access network side device of the second sensing node reaches a second preset threshold (e.g., the definition of the communication measurement can be the same as the communication measurement in Option 3 above, and the measurement value of the communication measurement reaching the second preset threshold can indicate poor communication quality or communication quality below the sensing performance requirements). For example, the measurement value of the communication measurement reaching the second preset threshold may include at least one of the following:

[0127] The reference signal received power RSRP is less than or equal to a first preset value;

[0128] The signal-to-noise ratio (SNR) is less than or equal to the second preset value;

[0129] The signal-to-interference-plus-noise ratio (SINR) is less than or equal to the third preset value;

[0130] The reference signal reception quality (RSRQ) is less than or equal to the fourth preset value;

[0131] The Received Signal Strength Indicator (RSSI) is less than or equal to the fifth preset value;

[0132] The bit error rate is greater than or equal to the sixth preset value;

[0133] The error rate is greater than or equal to the seventh preset value;

[0134] The throughput is greater than or equal to the eighth preset value;

[0135] The spectral efficiency is greater than or equal to the preset value.

[0136] The measured value of the communication measurement between the first sensing node and the access network side device of the first sensing node reaches the third preset threshold (when the first sensing node is a terminal, the terminal needs to communicate with the access network side device to realize the sensing function. At this time, if the communication quality between the first sensing node and the access network side device is poor, the sensing performance will be reduced).

[0137] Option six is ​​an indication message indicating whether a preset switching condition is met. The preset switching condition is used to trigger a switch in the perception mode of the perceived target from the first perception mode to the second perception mode.

[0138] In practice, meeting the preset switching conditions can be understood as the occurrence of the aforementioned preset event. At this time, the perception performance under the first perception mode is low or insufficient to meet the perception requirements. Therefore, the perception performance can be improved by switching the perception mode to the second perception mode.

[0139] It is worth mentioning that the aforementioned handover measurement report may include at least two of the options one to six mentioned above. Based on the handover measurement report, the first node can determine whether the second sensing method can achieve better sensing performance compared to the first sensing method.

[0140] As an optional implementation, before the first node determines whether to switch the sensing mode of the sensing target from the first sensing mode to the second sensing mode based on the switching measurement report, the sensing mode switching method further includes:

[0141] The first node sends a switch measurement request to the second sensing node, where the second sensing node is the signal receiving node under the first sensing mode.

[0142] The first node receives the switching measurement report from the second sensing node.

[0143] The handover measurement request is used to request the second sensing node to measure and report the aforementioned handover measurement report.

[0144] In this embodiment, the first node may be the same device as the first sensing node, or the first node may be a core network device (e.g., a sensing function network element; for ease of explanation, the core network device is uniformly referred to as the first device in this embodiment), or, in the case that the second sensing node is a terminal, the first node may be the access network side device of that terminal.

[0145] For example: in such Figure 4In the first sensing method shown in scenario (a), the first node can be at least one of the first device, base station A, and the access base station of the UE, and the second node is the UE;

[0146] In such Figure 4 In the first sensing method shown in scenario (b), the first node can be at least one of the first device and base station A, and the second node is base station B;

[0147] In such Figure 4 In the first sensing method shown in scenario (c), the first node can be at least one of the access base stations of the first device, UE A and UE B, and the second node is UE B.

[0148] In one possible implementation, during the process of sensing the target using the first sensing method, the first node can periodically send a switching measurement request to the second sensing node to periodically detect whether it is necessary to switch the sensing method to the second sensing method.

[0149] In another possible implementation, during the process of sensing the target using the first sensing method, the first node can send a switching measurement request to the second sensing node only when a preset event has occurred. This can reduce the frequency of the second sensing node performing measurements related to switching sensing methods.

[0150] Optionally, the preset event includes at least one of the following:

[0151] The state of the perceived target changes;

[0152] The position of the first sensing node has changed; the first sensing node is the signal transmitting node under the first sensing method.

[0153] The position of the second sensing node changes;

[0154] The environment of the sensing area where the sensing target is located changes;

[0155] The sensing resources available to the first sensing node have changed.

[0156] The sensing resources available to the second sensing node have changed;

[0157] The measured value of the sensed quantity acquired by the second sensing node reaches the first preset threshold;

[0158] The measurement value of the communication measurement acquired by the second sensing node or the measurement value of the communication measurement between the second sensing node and the access network side device of the second sensing node reaches the second preset threshold.

[0159] The measured value of the communication measurement between the first sensing node and the access network side device of the first sensing node reaches the third preset threshold.

[0160] The preset event has the same meaning as the preset event in the above embodiments, and is not specifically limited here. Based on the preset event, when the sensing performance is reduced, the measurement related to switching sensing mode can be triggered, which can reduce the frequency of the second sensing node performing the measurement related to switching sensing mode, reduce resource consumption, and reduce the energy consumption of the second sensing node.

[0161] Optionally, before the first node receives the switching measurement report from the second sensing node, the method further includes:

[0162] The first node sends first configuration information to the second sensing node, wherein the first configuration information is used to configure the second sensing node to perform handover measurement and obtain the handover measurement report.

[0163] In one implementation, the first node can send first configuration information and first request information to the second sensing node, wherein the first request information is used to request the recipient of the first request information to perform a second sensing of the sensing target after completing the sensing mode switch.

[0164] In one implementation, the aforementioned first configuration information may be carried in the first request information so that the second sensing node can be requested to perform measurements related to switching sensing modes through a single message, and the second sensing node can be configured to perform measurements and report.

[0165] In implementation, the aforementioned first configuration information can configure which signals the second sensing node needs to measure, which measurement quantities to measure, and how to report the switchover measurement report, etc. For example, the first configuration information includes at least one of the following:

[0166] The measurement object indication information, the measurement report configuration information corresponding to the switched measurement report, the configuration information of the target event, and the measurement identifier;

[0167] The measurement object indication information includes identification information of a second signal used to perform the switching measurement, a sensing measurement quantity associated with the second signal, and sensing parameter configuration information of the second signal. The target event is used to trigger the execution of the switching measurement. One measurement identifier corresponds to one measurement object and one measurement report configuration information.

[0168] In implementation, the measurement report configuration corresponding to the aforementioned handover measurement report can include the principles for reporting the handover measurement report, such as periodic reporting or event-triggered reporting. Furthermore, the measurement report configuration can also configure the format of the measurement report, such as the maximum number of cells and beams to be reported.

[0169] The aforementioned target events and related parameters may include: event definition, event-related parameters, and switching decision conditions. For example, the event that the second sensing node needs to measure is defined as detecting a certain action of the sensing target (e.g., assuming the sensing target is a person and the event to be measured is a fall). The aforementioned event-related parameters may be parameters used to determine whether the detected event is related to the defined target event. The switching decision conditions may be decision conditions used to determine whether to switch the sensing mode from the first sensing mode to the second sensing mode.

[0170] The aforementioned measurement identifier is used to identify measurement behavior, such as identifying a target event for measuring a certain measurement object. By using the measurement identifier corresponding to a measurement object and a measurement report configuration corresponding to a switching measurement report, a one-to-one correspondence can be established between the measurement object and the measurement report configuration corresponding to the switching measurement report. This enables the second sensing node to determine the object to be measured based on the measurement identifier, as well as the configuration used in the process of measuring and reporting the switching measurement.

[0171] It should be noted that, in addition to the first node sending a first request message to the second sensing node to request the second sensing node to perform measurements related to switching sensing modes, the second sensing node can also proactively perform measurements related to switching sensing modes and report a switching measurement report. Furthermore, the aforementioned switching measurement report may also be obtained from measurements taken by other sensing nodes besides the second sensing node; this is not specifically limited here.

[0172] As an optional implementation, when the first node determines, based on the switching measurement report, to switch the sensing mode of the perceived target from the first sensing mode to the second sensing mode, the sensing mode switching method further includes:

[0173] The first node sends a sensing end command to the third sensing node, wherein the third sensing node includes at least one of the signal receiving node and the signal sending node under the first sensing mode, and the third sensing node does not include the target sensing node. The sensing end command is used to notify the third sensing node to end the sensing operation on the sensing target. The target sensing node is the sensing node used to perform the sensing operation according to the second sensing mode after the sensing mode switch is completed.

[0174] In practice, when the third sensing node receives a sensing end command, it will terminate the sensing operation on the sensing target based on the sensing end command, thereby saving the resource waste and energy consumption caused by the third sensing node continuing to perform sensing operations on the sensing target.

[0175] In one implementation, the first node may send a sensing end command to the third sensing node when it determines that the sensing mode of the sensing target will be switched from the first sensing mode to the second sensing mode.

[0176] In one implementation, the first node can send a sensing end command to the third sensing node while sending a switching measurement request to the second sensing node.

[0177] In one implementation, before the first node sends a sensing end command to the third sensing node, the sensing mode switching method further includes:

[0178] The first node receives a handover success message from the target sensing node, wherein the target sensing node sends the handover success message after acquiring at least one measurement value and / or sensing result of a sensing measurement.

[0179] Compared to the other two implementation methods, this embodiment adopts a soft switching process for switching sensing methods. That is, the first sensing method is only terminated after ensuring that the target sensing node starts to perform sensing according to the second sensing method, so that the sensing of the target is not interrupted.

[0180] Optionally, the target sensing node sends the aforementioned handover success message after acquiring at least one measurement value of a sensing measurement quantity or at least one sensing result in accordance with the second sensing method.

[0181] In this way, the first perception method can be terminated when the target perception node can correctly perform perception according to the second perception method, reducing the problem of perception interruption caused by perception failure during the process of the target perception node perceiving the target according to the second perception method.

[0182] Of course, in practical applications, a hard handover process can also be used to switch the sensing mode. For example, at the same time the first node sends a switching command to the target sensing node, a sensing end command is sent to the third sensing node. No specific limitation is made here.

[0183] As an optional implementation, when the first node determines to switch the sensing mode of the perceived target from the first sensing mode to the second sensing mode, the method further includes:

[0184] The first node determines the target sensing node from the candidate sensing nodes. The target sensing node is the sensing node used to perform sensing operations according to the second sensing mode after the sensing mode switch is completed.

[0185] In practice, the aforementioned candidate sensing nodes can be those nodes that the first node considers to be able to sense the target after switching sensing modes.

[0186] In one implementation, when the first node stores prior information such as the capability information and resource information of the candidate sensing nodes, the first node can determine the target sensing node from the candidate sensing nodes based on this prior information.

[0187] In one implementation, the first node determines the target sensing node from candidate sensing nodes, further comprising:

[0188] The first node sends a first request message to the candidate sensing node or the access network side device of the candidate sensing node, wherein the first request message is used to request the candidate sensing node to perform a sensing operation on the sensing target according to the second sensing method;

[0189] When the first node receives the first response information, the first response information indicates that the first candidate sensing node agrees to perform a sensing operation on the sensing target according to the second sensing method, and the candidate sensing node includes the first candidate sensing node.

[0190] The first node determines the first candidate sensing node as the target sensing node.

[0191] The first request information may carry at least one of the following:

[0192] Perception needs can include, for example, the target area to be perceived, the type of object, the required perception functions, the purpose of perception, and the perception results.

[0193] The perceived quality of service (QoS) may include, for example, at least one of the following: perception resolution (further divided into: ranging resolution, angle measurement resolution, velocity measurement resolution, and imaging resolution, etc.), perception accuracy (further divided into: ranging accuracy, angle measurement accuracy, velocity measurement accuracy, and positioning accuracy, etc.), perception range (further divided into: ranging range, velocity measurement range, angle measurement range, imaging range, etc.), perception latency (e.g., the time interval from sending a perception signal to obtaining a perception result, or the time interval from initiating a perception request to obtaining a perception result), perception update rate (e.g., the time interval between two consecutive perception operations and obtaining perception results), detection probability (e.g., the probability of correctly detecting a perceived object when it exists), false alarm probability (e.g., the probability of incorrectly detecting a perceived target when it does not exist), perception security, and perception privacy.

[0194] Sensing and measuring quantity;

[0195] The sensing measurement results may include, for example, sensing results obtained directly or indirectly based on the measurement values ​​of at least one sensing measurement quantity;

[0196] The perception conditions may include at least one of the following: perception start time, perception end time, perception duration, etc.

[0197] Prior information about the target or area to be sensed may include at least one of the following: target type, approximate location / area of ​​the target, and historical state of the target (velocity, angle, distance, acceleration, spatial orientation).

[0198] The successful switching of sensing mode is determined by the following conditions (e.g., indicating that the measurement value of at least one sensing measurement and / or the measurement result of the communication measurement reaches a preset threshold within a preset time / preset number of times).

[0199] In this embodiment, the first node sends a first request message to each candidate sensing node or to the access network side device of the candidate UE, requesting these candidate nodes to perform sensing operations on the sensing target according to the second sensing method after switching sensing methods. In this way, if the first candidate sensing node among these candidate sensing nodes determines that it can perform sensing operations on the sensing target according to the second sensing method based on the first request message, it can send back a first response message to the first node. At this time, the first node can determine the first candidate sensing node as the target sensing node based on the first response message received from the first candidate sensing node.

[0200] It should be noted that, for other candidate sensing nodes besides the first candidate sensing node, if it is determined from the first request information that they cannot perform sensing operations on the sensing target in accordance with the second sensing method, they can send back a first rejection message to the first node. At this time, the first node can select the target sensing node from other candidate sensing nodes based on the first rejection message received.

[0201] It is worth noting that when the first node is a base station or the first device (i.e., core network equipment), and the candidate sensing nodes include candidate UEs, the first node can send a first request message to the access network side equipment (i.e., the candidate access base station) of the candidate UE. In this case, the first request message can request the candidate access base station to find the candidate UE so that the candidate UE can perform sensing operations on the sensing target according to the second sensing method after the sensing mode switch is completed. Specifically, after receiving the first request message, the candidate access base station can send a handover measurement request to at least one candidate UE. This handover measurement request is used to request the receiver to perform sensing operations on the sensing target according to the second sensing method after the sensing mode switch is completed. The candidate UE can then send back a first response message or a first rejection message to the candidate access base station. The candidate access base station can then select the target UE from the candidate UEs that have sent back the first response message and send back the target UE's indication information to the first node. This indication information can instruct the target UE to perform sensing operations on the sensing target according to the second sensing method after the sensing mode switch is completed. Thus, the first node can determine the target UE as the target sensing node.

[0202] In one implementation, the first node can send a first request message to a candidate sensing node each time, and when it receives a first rejection message, it can send the first request message to the next candidate sensing node, and so on, until it receives a first response message from the first candidate sensing node, and thus determine the first candidate sensing node as the target sensing node.

[0203] In one implementation, the first node may simultaneously send a first request message to at least two candidate sensing nodes, and upon receiving a first response message from at least two first candidate sensing nodes, select one of these at least two first candidate sensing nodes as the target sensing node using other methods, such as selecting the one with the strongest capability as the target sensing node.

[0204] Optionally, before the first node determines the first candidate sensing node as the target sensing node from the candidate sensing nodes, the method further includes:

[0205] The first node determines candidate sensing nodes from the preset sensing node set based on the first information of each sensing node in the preset sensing node set. The candidate sensing nodes include the target sensing node. The first information includes at least one of the following:

[0206] Location information;

[0207] Antenna panel orientation information;

[0208] Status information;

[0209] Perceptual ability information;

[0210] Resource information that can be used to perceive business needs;

[0211] Channel state information.

[0212] The preset set of sensing nodes can be all nodes in the device information list stored by the first node. For example, if the first node is a base station, the preset set of sensing nodes can include all UEs connected to that base station, as well as other base stations communicating with that base station. In this case, the device information list can include the device information of each sensing node, such as location information, antenna resource information, capability information, and resource configuration information. Thus, the first node can determine which sensing nodes support sensing operations on the target according to the second sensing method based on this device information, thereby identifying these sensing nodes as candidate sensing nodes for the target sensing node.

[0213] For example, for a terminal, a candidate terminal can be determined based on at least one of the following:

[0214] Terminal location information;

[0215] Terminal antenna panel orientation information;

[0216] The terminal's status information may include, for example, the speed of movement, the direction of movement, and the time period during which it remains stationary or in motion;

[0217] The terminal's sensing capability information may include, for example, the terminal's sensing coverage area, the maximum bandwidth available for sensing, the maximum duration of sensing services, the types and frame formats of sensing signals that can be supported, and the terminal's antenna array information (such as array type, number of antennas, array aperture, antenna polarization characteristics, array element gain and directivity characteristics, etc.).

[0218] The terminal can currently use the following resource information for sensing: time resources (number of symbols, number of time slots, number of frames, etc.), frequency resources (such as the number of resource blocks (RBs), the number of resource elements (REs), total bandwidth, available frequency band locations, etc.), antenna resources (such as the number of antenna arrays / antenna subarrays), phase modulation resources (such as the number of hardware phase shifters), and orthogonal code resources (such as the length and number of orthogonal codes).

[0219] The terminal's channel state information may include, for example, at least one of the following: channel transfer function / channel impulse response of at least one communication link, channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator, SSB resource indicator, layer indicator (LI), rank indicator (RI), and L1-Reference Signal Received Power (L1-RSRP).

[0220] For network-side devices, candidate network-side devices can be determined based on at least one of the following:

[0221] Location information of network-side devices;

[0222] The antenna panel of the network-side device is oriented towards the information;

[0223] Information on the sensing capabilities of network-side devices may include, for example, the sensing coverage area of ​​the network-side devices, the maximum bandwidth available for sensing, the maximum duration of sensing services, the types and frame formats of sensing signals that can be supported, and the antenna array information of the network-side devices (such as array type, number of antennas, array aperture, antenna polarization characteristics, array element gain and directivity characteristics, etc.).

[0224] The network-side devices can currently use the following resource information for sensing: time resources (number of symbols, number of time slots, number of frames, etc.), frequency resources (such as the number of resource blocks (RBs), the number of resource elements (REs), total bandwidth, available frequency band locations, etc.), antenna resources (such as the number of antenna arrays / antenna subarrays), phase modulation resources (such as the number of hardware phase shifters), and orthogonal code resources (such as the length and number of orthogonal codes).

[0225] The channel state information of the network-side equipment may include, for example, at least one of the following: channel transfer function / channel impulse response of at least one communication link, channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator, SSB resource indicator, layer indicator (LI), rank indicator (RI), and L1-Reference Signal Received Power (L1-RSRP).

[0226] In this embodiment, the first node can select a target sensing node from a large number of candidate sensing nodes, so that the selected target sensing node can perceive the sensing target according to the second sensing method.

[0227] It should be noted that, in practice, the node used to select the target sensing node from a large number of candidate sensing nodes may also be other nodes besides the first node. For example, if the first node is the first device, the node used to select the target sensing node from a large number of candidate sensing nodes may be the source base station (i.e., the base station that participated in the first sensing mode before switching sensing modes) or the source access base station (i.e., the base station accessed by the UE that participated in the first sensing mode before switching sensing modes).

[0228] As an optional implementation, the sensing mode switching method further includes:

[0229] The first node sends a switching command to the target sensing node, wherein the switching command is used to notify the target sensing node to perform sensing operations according to the second sensing method.

[0230] In this embodiment, after determining the target sensing node, the first node also sends a switching command to the target sensing node so that the target sensing node performs sensing operations according to the second sensing method based on the switching command.

[0231] Optionally, the switching command includes third configuration information, which is used to configure the perception parameters for the target perception node to perform perception operations according to the second perception method; and / or,

[0232] The first response information includes second configuration information, which is used to configure the perception parameters for the target perception node to perform perception operations according to the second perception method.

[0233] In one implementation, the switching command includes third configuration information, which is used to configure the perception parameters for the target perception node to perform perception operations according to the second perception method. Thus, the target perception node can determine the parameter configuration information for performing the second perception operation based on this third parameter configuration information.

[0234] In one implementation, the first response information includes second configuration information, which is used to configure the perception parameters for the target sensing node to perform sensing operations according to the second sensing method. Thus, the first node can configure the perception parameters related to the second sensing operation according to the second configuration information recommended by the target sensing node.

[0235] In one implementation, the first response information includes second configuration information, and the switching command includes third configuration information.

[0236] In this embodiment, the first response information fed back by the target sensing node to the first node may carry second parameter configuration information. This second parameter configuration information may represent the parameter configuration information suggested by the target sensing node for performing the second sensing. The aforementioned third parameter configuration information may be the same as or different from the second parameter configuration information. After switching sensing modes, the parameter configuration information actually used by the target sensing node during the execution of the second sensing process may be the second parameter configuration information, the third parameter configuration information, or a fourth parameter configuration information determined based on the second and third parameter configuration information; no specific limitation is made here. In this way, the target sensing node can perform the second sensing by combining the second parameter configuration information recommended by the target sensing node and the third parameter configuration information configured by the first node.

[0237] Optionally, the second configuration information includes at least one of the following:

[0238] Waveform type, subcarrier spacing, guard interval, bandwidth, data burst duration, time domain spacing, transmitted signal power, signal format, signal direction, time resources, frequency resources, quasi-co-located QCL relationship, antenna configuration information;

[0239] And / or,

[0240] The third configuration information includes at least one of the following:

[0241] Waveform type, subcarrier spacing, guard interval, bandwidth, data burst duration, time domain spacing, transmitted signal power, signal format, signal direction, time resources, frequency resources, quasi-co-located QCL relationship, and antenna configuration information.

[0242] Among them, waveform types include: for example, Orthogonal frequency division multiplexing (OFDM), Single Carrier Frequency Division Multiple Accessing (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), pulse signals, etc.

[0243] Subcarrier spacing: For example, the subcarrier spacing of an OFDM system is 30 kHz;

[0244] Guard interval: This represents the time interval from the end of signal transmission to the moment the latest echo of that signal is received. This parameter is proportional to the maximum sensing distance. For example, it can be expressed as a 2d... max / c is calculated to obtain d max This refers to the maximum sensing distance (related to sensing requirements). For example, for spontaneously generated and received sensing signals, d... max It represents the maximum distance from the sensing signal transceiver point to the signal transmitter point; in some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval.

[0262] In this embodiment, when the first candidate sensing node feeds back recommended sensing parameter configuration information to the first node through the first response information, each first candidate sensing node, after determining to switch to the second sensing mode, can perform sensing operations according to the recommended sensing parameter configuration information, thereby further improving sensing performance. Furthermore, when the first node sends third configuration information to the target sensing node through a switching command, the target sensing node can, after completing the sensing mode switch, perform second sensing based on at least one of its recommended second and third configuration information.

[0263] Optionally, the first response information may further include communication measurements and their values. Thus, when at least two first candidate sensing nodes agree to perform sensing operations on the sensing target according to the second sensing method, each first candidate sensing node can select the target sensing node from among the first candidate nodes with better communication measurements by feeding back the measured values ​​of the communication measurements, thereby improving sensing performance.

[0264] Optionally, the second configuration information and / or the third configuration information include first switching mode configuration information, wherein the first switching mode configuration information is used to configure the termination of the first sensing mode when the second sensing mode is successfully established.

[0265] When the second sensing mode is successfully established, ending the first sensing mode can indicate that the switching of sensing modes adopts a soft handover process. In this case, when the switching of sensing modes adopts a soft handover process, the sensing operation in the soft handover process can be configured according to the first handover mode configuration information.

[0266] As an optional implementation, when the first node determines to switch the sensing mode of the sensing target from the first sensing mode to the second sensing mode, the sensing mode switching method further includes:

[0267] The first node sends a first indication message, wherein the first indication message is used to notify the recipient of the first indication message that after the perception mode switch is completed, the target perception node performs a perception operation on the perception target according to the second perception mode.

[0268] In this embodiment, when the first node determines that it will switch the sensing method of the sensing target from the first sensing method to the second sensing method, it can send first indication information to the core network equipment, source base station, etc., to instruct the recipient of the first indication information that, after the sensing method switch is completed, the target sensing node will perform sensing operations on the sensing target according to the second sensing method. In this way, the recipient of the first indication information can perform subsequent operations based on the first indication information. For example, the first device can determine whether to switch the sensing method and / or the nodes participating in the sensing process based on this information during subsequent sensing processes.

[0269] As an optional implementation, when the first node determines to switch the sensing mode of the sensing target from the first sensing mode to the second sensing mode, the sensing mode switching method further includes:

[0270] The first node sends a second indication message, wherein the second indication message is used to instruct the signal transmitting node and / or signal receiving node under the first sensing mode to exit the sensing operation on the sensing target after completing the sensing mode switch.

[0271] In this embodiment, when the first node determines that it will switch the sensing method for the sensing target from the first sensing method to the second sensing method, it can send the aforementioned second indication information to the sensing node that performed the first sensing before the sensing method switch, or to the access base station of the sensing node that performed the first sensing, to instruct it to no longer perform the sensing operation for the sensing target. For example, when the first device determines that it will switch the first sensing between base station A and UE to the second sensing between base station B, the first device can send the second indication information to base station A and UE respectively, to instruct base station A and UE to no longer participate in sensing after the sensing method switch is completed.

[0278] In practice, the sensing measurement quantity in the sensing reference information before switching the sensing mode may be the same as or different from the sensing measurement quantity of the target sensing node after switching the sensing mode, without being specifically limited here.

[0279] In this embodiment, the first node sends the aforementioned perception reference information to the target perception node, enabling the target perception node to perform second perception based on this perception reference information, thereby improving the perception performance of the target.

[0280] In this embodiment, the first node determines whether to switch the sensing method of the target from the first sensing method to the second sensing method based on the switching measurement report. The switching measurement report includes measurement results used to determine the switching sensing method. The signal transmitting node and the signal receiving node of the first sensing method are different nodes, while the signal transmitting node and the signal receiving node of the second sensing method are the same node. Thus, during the sensing node's sensing measurement of the target based on the first sensing method, the first node can determine, based on the switching measurement report, whether the second sensing method is more suitable for the target's state, environment, etc., and accordingly decide whether to switch from the first sensing method to the second sensing method. This ensures that the sensing method is more compatible with the target's state or environment, resulting in more accurate sensing results and improved reliability of the sensing measurement process.

For example... Figure 5 As shown, the second sensing mode switching method may include the following steps:

[0282] Step 501: The target sensing node receives a first request message, wherein the first request message is used to request the target sensing node to perform a sensing operation on the sensing target in accordance with the second sensing method.

In this way, the first node can control the source sensing node to end the first sensing based on the handover success message, so as to realize the soft handover process of sensing mode.

[0295] Of course, in practice, the first node may also control the source sensing node to end the first sensing before receiving the handover success message, thus achieving a hard handover of sensing methods. In this case, the first node can determine that the target sensing node has successfully executed the second sensing based on the handover success message. In other words, if the first node does not receive a handover success message from the target sensing node within a preset time period, it can control the source sensing node to continue executing the first sensing, select another sensing node to execute the second sensing, or terminate the sensing service, etc.

[0402] In this embodiment, when the first sensing node and the target sensing node are not the same node, the first sensing node terminates its first sensing of the target based on the received sensing termination command, thereby saving the first sensing node's resources and reducing its energy consumption.

[0403] Optionally, the switching measurement report includes at least one of the following:

[0404] At least one measured value of a sensed quantity;

[0409] Indication information used to indicate whether preset switching conditions are met, wherein the preset switching conditions are used to trigger the switching of the perception mode of the perceived target from the first perception mode to the second perception mode.

[0410] The meaning and function of each item in the aforementioned switchover measurement report are as follows: Figure 2 The meanings and functions of the various items in the switching measurement report in the illustrated method embodiment are the same, and will not be repeated here.

[0411] Optionally, the sensing mode switching method further includes:

[0412] The first sensing node receives first indication information, wherein the first indication information is used to notify the first sensing node that after the sensing mode switch is completed, the target sensing node performs a sensing operation on the sensing target according to the second sensing mode. The target sensing node is the sensing node used to perform the sensing operation according to the second sensing mode after the sensing mode switch is completed.

[0413] The meaning and function of the aforementioned first instruction information are similar to those of... Figure 2 The meaning and function of the first indication information in the illustrated method embodiment are the same, and will not be repeated here.

[0414] Optionally, the sensing mode switching method further includes:

[0415] The first sensing node receives second indication information, wherein the second indication information is used to instruct the first sensing node to exit the sensing operation on the sensing target after completing the sensing mode switch.

[0416] The second sensing node receives a second indication message, wherein the second indication message is used to instruct the second sensing node to exit the sensing operation on the sensing target after completing the sensing mode switch.

[0417] The meaning and function of the aforementioned second instruction information are as follows: Figure 2 The meaning and function of the second instruction information in the illustrated method embodiment are the same, and will not be repeated here.

[0418] Optionally, the sensing mode switching method further includes:

[0419] The first sensing node sends sensing reference information to the target sensing node, wherein the target sensing node is a sensing node that performs sensing operations according to the second sensing mode after completing the sensing mode switch, and the sensing reference information includes at least one of the following:

[0420] Historical measurement values ​​of the perceived measurement quantity of the target;

[0421] Historical perception results of the perceived target;

[0424] The meaning and function of each item in the aforementioned perceived reference information are as follows: Figure 2 The meanings and functions of the various contents of the perceived reference information in the illustrated method embodiments are the same, and will not be repeated here.

[0425] The sensing mode switching method executed by the first sensing node provided in this application embodiment is similar to... Figure 2 The first node shown executes the perception mode switching method. Figure 5 The method for switching perception modes performed by the target perception node shown, and Figure 6 The sensing mode switching method executed by the second sensing node shown is based on the same concept, enabling the first node, the target sensing node, and the first and second sensing nodes to cooperate in executing the sensing mode switching method, thus achieving the same results as... Figure 2 The same beneficial effects are achieved in the illustrated method embodiments, and will not be repeated here to avoid repetition.

[0426] It is worth noting that, in a special case, the target sensing node and the first sensing node can be the same node. For example, the first sensing node, as one of the candidate sensing nodes, receives the first request information and sends back the first response information. Another example is that, upon obtaining a handover measurement report, the target sensing node determines, based on that report, that it can support performing second sensing on the target.

[0427] In a special case, the first node and the first sensing node can be the same node. In this case, the first sensing node can send a first request message to the candidate sensing node and receive a first response message when it determines that the sensing method of the sensing target will be switched from the first sensing method to the second sensing method. The first request message requests the candidate sensing node to perform sensing operation on the sensing target according to the second sensing method, and the target sensing node is determined according to the received first response message.

[0428] To facilitate the explanation of the execution functions of each node in the sensing mode switching method provided in the embodiments of this application, as follows: Figure 4 Taking the six combinations shown as examples, the sensing mode switching method provided in this application embodiment will be illustrated:

[0429] Example 1: The first sensing operation performed by the base station and the UE is switched to the second sensing operation performed by the base station.

[0430] Assuming that the base station and UE are already performing the first sensing operation, the base station performing the first sensing operation before the handover is referred to as the source base station, and the base station performing the second sensing operation after the handover is referred to as the target base station; the UE is the UE performing the first sensing operation, then the sensing mode switching method provided in this application embodiment may include the following steps:

[0431] Step 11: Perform a handover measurement on the network.

[0432] This step can be divided into the following situations:

[0433] (11-1) Base station-UE performs downlink awareness:

[0434] The source base station sends a handover measurement request to the UE. After receiving the handover measurement request, the UE performs handover measurement and sends a handover measurement report back to the source base station.

[0435] or,

[0436] The first device (e.g., a sensing function network element) sends a handover measurement request to the UE. After receiving the handover measurement request, the UE performs handover measurement and sends a handover measurement report back to the first device. Optionally, the UE or the first device sends a handover measurement report to the source base station.

[0437] Specifically, before the UE performs handover measurements, the first device or the source base station sends first configuration information to the UE, or carries the first configuration information in the handover measurement request.

[0438] (11-2) Base station-UE performs uplink sensing:

[0439] The source base station performs handover measurements.

[0440] Optionally, before the source base station performs handover measurements, the first device or UE sends a handover measurement request to the source base station.

[0441] Specifically, before the source base station performs handover measurements, the first device or UE sends first configuration information to the source base station. Alternatively, the first configuration information is included in the handover measurement request.

[0442] The above first configuration information is consistent with... Figure 2 The first configuration information in the method embodiments shown has the same content and meaning, and will not be repeated here.

[0443] Step 12: The source base station decides whether to initiate a handover based on the handover measurement report.

[0444] Optionally, the source base station reports a handover measurement report to the first device, and the first device decides whether to initiate a handover request. Alternatively, the first device decides whether to initiate a handover request based on the handover measurement report received from the UE.

[0445] If no switch is initiated, the subsequent processing can be to maintain or terminate the current first perception.

[0446] If a handover is initiated, the first device or the source base station determines which node will switch to the second sensing mode, specifically in the following scenarios:

[0447] Case 12-1: The source base station decides to switch to the base station to perform the second sensing.

[0448] The source base station sends a first request message to at least one candidate target base station. The first request message requests the first request message recipient to perform the second sensing after the sensing mode switch is completed.

[0449] Optionally, the source base station sends a first indication message to the first device. The first indication message is to notify the recipient of the first indication message that the base station will perform the second perception after the perception mode is switched.

[0450] Optionally, the source base station sends a second indication information to the UE, the second indication information being an instruction to the recipient of the second indication information to no longer participate in sensing after the sensing mode switch is completed.

[0451] Case 12-2: The first device decides to switch to the base station to perform the second sensing mode.

[0452] The first device sends a first request message to at least one candidate target base station.

[0453] Optionally, the first device sends a first indication message to the source base station.

[0454] Optionally, the first device sends a second indication message to the UE.

[0455] In this scenario 12-2, the candidate target base station may include the source base station.

[0456] Scenario 12-3: The source base station decides to proactively switch to performing secondary sensing. In this case, the source base station is the candidate target base station.

[0457] The source base station sends a third indication message (base station-UE performs downlink sensing) or a fourth indication message (base station-UE performs uplink sensing) to the first device. The third or fourth indication message is an instruction to the recipient of the third indication message. After the sensing mode is switched, the sender of the third or fourth indication message can perform the second sensing.

[0458] Optionally, this situation 12-3 may include situation 12-1. For example, if the source base station determines that it needs to switch to the second sensing mode based on the handover measurement, it may determine that it will perform the second sensing if its own capability information supports the second sensing of the sensing target.

[0459] Optionally, the first request information may include a soft handover request. For example, the first configuration information may include first handover mode configuration information.

[0460] Step 13: The candidate target base station decides whether to accept performing the second sensing after switching sensing modes.

[0461] 13-1) If agreed, the candidate target base station sends a first response message to the sender of the first request message (source base station or first device). The first response message is an instruction to the sender of the first request message that, after the sensing mode switch is completed, the sender of the first response message agrees to perform the second sensing.

[0462] Optionally, the candidate target base station may provide suggested second configuration information in the first response information. This second configuration information is used to configure the sensing parameters for the candidate target sensing node to perform the second sensing operation.

[0463] Optionally, if the first request information includes a soft handover request, and the candidate target base station agrees to and supports soft handover, then the second configuration information includes the first handover mode configuration information. The first handover mode configuration information will have some configuration information specifically for soft handover compared to the second configuration information.

[0464] 13-2) If disagreement is not made, the candidate target base station may send a first rejection message to the sender of the first request message (source base station or first device). The first rejection message is an instruction to the sender of the first request message not to perform the second perception.

[0465] The follow-up processing can be one of the following:

[0466] i. The source base station or the first device re-determines the candidate target base station;

[0467] ii. Maintain the current primary perception;

[0468] iii. End the current first perception.

[0469] Step 14: Based on the received first response information, the source base station or the first device determines at least one target base station among the candidate target base stations as the sensing node to perform the second sensing after the handover.

[0470] The source base station or the first device sends a handover command to the target base station. The handover command is used to notify the target sensing node to perform a second sensing operation.

[0471] Optionally, the source base station or the first device may provide suggested third configuration information in the handover command. This third configuration information is used by the target sensing node to configure sensing parameters for performing the second sensing operation.

[0472] Optionally, the third configuration information includes the first switching mode configuration information.

[0473] Step 15: The target base station performs the second sensing operation.

[0474] Specifically, the follow-up processing falls into the following two categories:

[0475] Scenario 1: If a soft handover method is used, the target base station configures the sensing parameters based on at least one of the first request information, the second configuration information, and the third configuration information, and performs the second sensing operation.

[0476] After obtaining at least one sensing measurement result and / or sensing result, the target base station sends a handover success message to the source base station or the first device.

[0477] Furthermore, this includes one of the following situations:

[0478] 15-1a) The sender of the first request information is the source base station, and the source base station and the target base station are not the same device:

[0479] After receiving the handover success message, the source base station sends a sensing end command to the UE. The source base station and the UE terminate the original sensing operation and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0480] 15-2a) The sender of the first request information is the first device, and the source base station and the target base station are not the same device:

[0481] After receiving the handover success message, the first device sends a sensing end command to the source base station and the UE. The source base station and the UE terminate their original sensing operations and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0482] 15-3a) The sender of the first request information is the first device, and the source base station and the target base station are the same device:

[0483] After receiving the handover success message, the first device sends a sensing end command to the UE. The UE terminates its original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0484] 15-4a) The source base station actively acts as the target base station:

[0485] After receiving the handover success message, the first device or the source base station sends a sensing end command to the UE. The UE ends its original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0486] Scenario 2: If a hard handover method is used, the source base station or the first device does not need to wait for a handover success message while performing step 14. This includes one of the following scenarios:

[0487] 15-1b) The sender of the first request information is the source base station, and the source base station and the target base station are not the same device:

[0488] The source base station sends a sensing end command to the UE. The source base station and the UE terminate the original sensing operation and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.);

[0489] 15-2b) The sender of the first request information is the first device, and the source base station and the target base station are not the same device:

[0490] The first device sends a sensing end command to the source base station and the UE. The source base station and the UE terminate their original sensing operations and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0491] 15-3b) The sender of the first request information is the first device, and the source base station and the target base station are the same device:

[0492] The first device sends a sensing end command to the UE. The UE terminates its original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0493] 15-4b) The source base station actively acts as the target base station:

[0494] The first device or source base station sends a sensing end command to the UE. The UE terminates its original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0495] Step 16: The source base station and / or the first device may send some or all of the historical sensing measurement values ​​and / or historical sensing results, sensing target / area prior information to the target base station.

[0496] Example 2: The first sensing performed by the base station is switched to the second sensing performed by the base station.

[0497] Assume that the base station sending the first signal is base station A, and the base station receiving the first signal is base station B. Base stations A and B are already performing the first sensing operation. Base stations A and B performing the first sensing operation before the handover are referred to as the source base stations, and the base station performing the second sensing operation after the handover is referred to as the target base station.

[0498] Step 21: Perform a network handover measurement.

[0499] Base station A sends a handover measurement request to base station B. After receiving the handover measurement request, base station B performs handover measurement and sends a handover measurement report back to base station A. Optionally, either base station A or base station B sends a handover measurement report to the first device.

[0500] or,

[0501] The first device (e.g., a sensing function network element) sends a handover measurement request to base station B. After receiving the handover measurement request, base station B performs handover measurement and sends a handover measurement report back to the first device. Optionally, base station B or the first device sends a handover measurement report to base station A.

[0502] or,

[0503] Base station B actively performs handover measurements and obtains a handover measurement report. Optionally, base station B sends the handover measurement report to the first device or base station A.

[0504] Specifically, before base station B performs handover measurements, base station A or the first device sends first configuration information to base station B. Alternatively, the first configuration information is included in the handover measurement request.

[0505] Step 22: Based on the handover measurement report, base station A decides whether to initiate a handover.

[0506] Optionally, base station A or base station B reports a handover measurement report to the first device, and the first device decides whether to initiate a handover request.

[0507] If no switch is initiated, the subsequent processing can be to maintain or terminate the current first perception.

[0508] If a handover is initiated, the first device or the source base station (including base station A and base station B) determines which node will switch to the second sensing mode, specifically in one of the following situations:

[0509] Scenario 22-1: Base station A decides to switch to base station A to perform the second sensing operation. Base station A sends a first request message to at least one candidate target base station.

[0510] Optionally, base station A sends a first indication message to the first device. The first indication message is to notify the recipient of the first indication message that the base station will perform the second perception after the perception mode is switched.

[0511] The candidate target base station may include base station B.

[0512] Scenario 22-2: Base station B decides to switch over to perform the second sensing operation. Base station B sends a first request message to at least one candidate target base station.

[0513] Optionally, base station B sends first indication information to the first device.

[0514] The candidate target base station includes base station A.

[0515] Scenario 22-3: The first device decides to switch to the base station to perform the second sensing mode. The first device sends a first request message to at least one candidate target base station.

[0516] Optionally, the first device sends a first indication message to base station A and / or base station B.

[0517] The candidate target base stations include base station A and base station B.

[0518] Scenario 22-4: Base station A decides to actively switch to performing the second sensing mode. Base station A sends a third indication message (base station A is the source receiving base station) or a fourth indication message (base station A is the source transmitting base station) to base station B and / or the first device. In this case, base station A is the candidate target base station, and the third or fourth indication message is an instruction to its receiver. After the sensing mode switch is completed, the sender of the third or fourth indication message can perform the second sensing mode.

[0519] Optionally, case 22-4 also includes case 22-1.

[0520] Scenario 22-5: Base station B decides to proactively switch to performing second sensing. Base station B sends third indication information to base station A and / or the first device. In this case, base station B is a candidate target base station.

[0521] Optionally, case 5 also includes case 2.

[0522] Optionally, the first request information may include a soft handover request.

[0523] Step 23: The candidate target base station decides whether to accept performing the second sensing after switching sensing modes.

[0524] 23-1) If agreed, the candidate target base station sends the first response information to the sender of the first request information (source base station or first device).

[0525] Optionally, the candidate target base station may provide suggested second configuration information in the first response information.

[0526] The second configuration information includes at least one of the following: Same as Example 1.

[0527] If the first request information includes a soft handover request, and the candidate target base station agrees to and supports the soft handover, then the second configuration information includes the first handover mode configuration information.

[0528] 23-2) If the candidate base station does not agree, it may send a first rejection message to the sender of the first request message (source base station or first device).

[0529] The follow-up processing can be one of the following:

[0530] i. The source base station or the first device re-determines the candidate target base station;

[0531] ii. Cancel the switch and maintain the current primary perception;

[0532] iii. End the current first perception.

[0533] Step 24: Same as step 14 in Example 1.

[0534] Step 25: The target base station performs the second sensing operation.

[0535] Specifically, the follow-up processing falls into the following two categories:

[0536] Scenario 1: If a soft handover method is used, the target base station configures the sensing parameters based on at least one of the first request information, the second configuration information, and the third configuration information, and performs the second sensing operation.

[0537] After obtaining at least one sensing measurement result and / or sensing result, the target base station sends a handover success message to the source base station or the first device.

[0538] Furthermore, this includes one of the following situations:

[0539] 25-1a) The sender of the first request information is base station A, and the source base station and the target base station are not the same device:

[0549] 25-6a) Base station A actively acts as the target base station:

[0550] After receiving the handover success message, the first device sends a sensing end command to base station B. After receiving the sensing end command from the first device or the handover success information from base station A, base station B terminates the original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0553] Scenario 1: If a hard handover method is used, then while executing step 24, the source base station or the first device does not need to wait for a handover success message. This specifically includes one of the following scenarios:

[0554] 25-1b) The sender of the first request information is base station A, and the source base station and the target base station are not the same device:

[0555] Base station A sends a sensing termination command to base station B. Base station A and base station B terminate their original sensing operations and release the resources occupied by sensing (including time and frequency resources, antenna port resources, etc.).

[0569] Example 3: The first sensing performed by the base station and UE is switched to the second sensing performed by the UE.

[0570] Assume that the base station and UE were already performing the first sensing operation before the handover. The UE performing the first sensing operation before the handover is called the source UE, and the UE performing the second sensing operation after the handover is called the target UE; the base station performing the first sensing operation before the handover is called the source base station, and the access base station of the target UE is called the target access base station.

[0571] Step 31: Same as step 11 in Example 1.

[0572] Step 32: The source base station decides whether to initiate a handover based on the handover measurement report.

[0573] Alternatively, the source base station may report a handover measurement report to the first device, which will then decide whether to initiate a first request.

[0574] Alternatively, the first device may decide whether to initiate a first request based on the handover measurement report received from the source UE.

[0575] If no switch is initiated, the subsequent processing can be to maintain or terminate the current first perception.

[0576] If a handover is initiated, the first device or the source base station determines which node will switch to the second sensing mode, specifically in one of the following scenarios:

[0578] The source base station sends a first request message to at least one candidate target UE. Alternatively, the source base station may send a second request message to at least one candidate target access base station, the second request message requesting the recipient of the second request message (i.e., the candidate target access base station) to find the candidate target UE and perform second sensing after the sensing mode switch is completed.

[0590] 33-1) If agreed, the candidate target UE sends the first response information to the sender of the first request information (source base station, or candidate target access base station, or first device).

[0591] Optionally, the candidate target access base station sends a second response information to the second request information sender (source base station or first device). The second response information indicates that the second request information sender agrees to perform the second sensing after the sensing mode switch is completed.

[0592] Optionally, the second response information includes part or all of the first response information.

[0593] Optionally, the candidate target UE may provide suggested second configuration information in the first response information.

[0594] Optionally, if the first request information includes a soft handover request, and the candidate target UE agrees to and supports soft handover, then the second configuration information includes the first handover mode configuration information.

[0595] 33-2) If the candidate UE does not agree, it sends a first rejection message to the sender of the first request message (source base station, or candidate access base station, or first device).

[0596] Optionally, the candidate target access base station sends a second rejection message to the sender of the second request information (source base station or first device). The second rejection message indicates to the sender of the second request information that the UE accessing the cell will not perform the second perception.

[0597] The follow-up processing can be one of the following:

[0598] i. The source base station or the first device re-determines the candidate target UE;

[0599] ii. The candidate target access base station redetermines the candidate target UE;

[0600] iii. The source base station or the first device re-determines the candidate target access base station, and the candidate target access base station determines the candidate target UE;

[0601] iv. Cancel the switch and maintain the current primary perception;

[0602] v. End the current first perception.

[0603] Step 34: Based on the received first response information and / or second response information, the source base station or the first device determines at least one target UE among the candidate target UEs as a sensing node to perform the second sensing after the handover.

[0604] The source base station or the first device sends a handover command to the target UE.

[0605] Optionally, the source base station or the first device may provide suggested third configuration information in the handover command.

[0606] Optionally, the third configuration information includes the first switching mode configuration information.

[0607] Step 35: The target UE performs second-level sensing. Specifically, subsequent processing is divided into the following two cases:

[0608] Scenario 1: If a soft handover method is used. The target UE configures the perception parameters based on at least one of the first request information, the second request information, the second configuration information, and the third configuration information, and performs the second perception.

[0609] After obtaining at least one measurement value and / or sensing result of the sensing measurement, the target UE sends a handover success message to the source base station or the first device.

[0610] Furthermore, this includes one of the following situations:

[0611] 35-1a) If the sender of the first request information or the second request information is the source base station, and the source UE and the target UE are not the same device:

[0612] After receiving the handover success message, the source base station sends a sensing end command to the source UE. The source base station and the source UE terminate the original sensing operation and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0613] 35-2a) The sender of the request information is the source base station, and the source UE and the target UE are the same device:

[0614] After receiving the handover success message, the source base station ends the original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0615] 35-3a) The sender of the request information is the first device, and the source UE and the target UE are not the same device:

The source base station terminates its original sensing operation and releases the resources occupied by the sensing (including time-frequency resources, antenna port resources, etc.).

[0619] 35-5a) The source UE actively acts as the target UE:

[0620] After receiving the handover success message, the first device sends a sensing end command to the source base station. The source base station terminates its original sensing operation and releases the resources occupied by the sensing (including time-frequency resources, antenna port resources, etc.).

[0621] Scenario 2: If a hard handover method is used, then while executing step 34, the source base station or the first device does not need to wait for a handover success message. This includes one of the following scenarios:

[0622] 35-1b) The sender of the request information is the source base station, and the source UE and the target UE are not the same device:

[0623] The source base station sends a sensing termination command to the source UE. The source base station and the source UE terminate the original sensing operation and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.);

[0624] 35-2b) The sender of the request information is the source base station, and the source UE and the target UE are the same device:

[0625] The source base station ends its original sensing operation and releases the resources occupied by sensing (including time and frequency resources, antenna port resources, etc.);

[0626] 35-3b) The sender of the request information is the first device, and the source UE and the target UE are not the same device:

[0627] The first device sends a sensing termination command to the source base station and the source UE. The source base station and the source UE terminate their original sensing operations and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0628] 35-4b) The sender of the request information is the first device, and the source UE and the target UE are the same device:

[0629] The first device sends a sensing termination command to the source base station. The source base station terminates the original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0630] 35-5b) The source UE actively acts as the target UE:

[0631] The source base station ends its original sensing operation and releases the resources occupied by sensing (including time and frequency resources, antenna port resources, etc.);

[0632] Step 36: The source base station and / or the first device may send some or all of the historical sensing measurement values ​​and / or historical sensing results, sensing target / area prior information to the target UE.

[0633] Example 4: The UE performs the first perception, then switches to the UE performing the second perception.

[0634] Assume that the UE sending the first signal is UE A, and the UE receiving the first signal is UE B. UE A and UE B are already performing the first sensing operation. UE A and UE B performing the first sensing operation before the handover are called the source UEs, and the access base station of the source UEs is called the source access base station (in implementation, UE A and UE B can be located in the same cell (cell A)). The UE performing the second sensing operation after the handover is called the target UE, and the access base station of the target UE is called the target access base station (wherein, the cell accessed by the target UE may be cell A or a cell other than cell A).

[0635] Step 41: Perform a handover measurement on the network.

[0636] UE A sends a handover measurement request to UE B. After receiving the handover measurement request, UE B performs handover measurement and sends a handover measurement report back to UE A. Optionally, UE A or UE B sends a handover measurement report to the source access base station and / or the first device (e.g., a sensing function network element).

[0637] or,

[0638] The source access base station sends a handover measurement request to UE B. After receiving the handover measurement request, UE B performs handover measurement and sends a handover measurement report back to the source access base station. Optionally, UE B or the source access base station sends a handover measurement report to the first device and / or UE A.

[0639] or,

[0640] The first device (e.g., a sensing function network element) sends a handover measurement request to UE B. After receiving the handover measurement request, UE B performs handover measurement and sends a handover measurement report back to the first device. Optionally, the first device sends a handover measurement report to the source access base station and / or UE A.

[0641] Before UE B performs handover measurements, any one of UE A, the source access base station, or the first device sends first configuration information to UE B. Alternatively, the first configuration information is included in the handover measurement request.

[0642] Step 42: The source access base station or the first device decides whether to initiate a handover based on the handover measurement report.

[0643] If no switch is initiated, the subsequent processing can be to maintain or terminate the current first perception.

[0644] If a handover is initiated, any one of the following—the first device, the source access base station, or the source UE (including UE A and UE B)—determines which node will switch to the second sensing mode, specifically in one of the following scenarios:

[0645] Case 42-1: The source access base station decides to switch to the UE to perform the second sensing.

[0646] The source access base station sends a first request message to at least one candidate target UE. Alternatively, the source access base station may send a second request message to at least one candidate target access base station, and the candidate target access base station may send the first request message to at least one candidate target UE.

This can be achieved by: the first device sending a second request message to at least one candidate target access base station, and the candidate target access base station sending the first request message to at least one candidate target UE.

[0651] Optionally, the first device sends a first indication message to the source access base station.

[0652] The candidate target UE may include the source UE, and the candidate target access base station may include the source access base station.

[0653] Case 42-3: UE A decides to actively switch to performing second sensing. UE A sends third indication information to the source access base station and / or the first device. In this case, UE A is a candidate target UE.

[0654] Optionally, at least one of UE A, the source access base station, and the first device sends a second indication message to UE B.

[0655] Optionally, case 42-3 also includes case 42-1 or case 42-2.

[0656] Case 42-4: UE B decides to actively switch to performing second sensing. UE B sends third or fourth indication information to the source access base station and / or the first device. In this case, UE B is a candidate target UE.

[0657] Optionally, at least one of UE B, the source access base station, and the first device sends a second indication message to UE A.

[0665] Optionally, if the first response information includes a soft handover request, and the candidate target UE agrees to and supports the soft handover, then the second configuration information includes the first handover mode configuration information.

[0666] 43-2) If the candidate UE does not agree, it may send a first rejection message to the sender of the first request message (source access base station, candidate access base station, or first device).

[0667] Optionally, the candidate target access base station sends a second rejection message to the second request information sender (source access base station or first device).

[0672] iv. Cancel the switch and maintain the current primary perception;

[0673] v. End the current first perception.

[0674] Step 44: The source access base station or the first device determines at least one target UE from the candidate target UEs based on the received first response information and / or second response information, as the sensing node to perform the second sensing after the handover.

[0675] The source access base station or the first device sends a handover command to the target UE.

[0676] Optionally, the source access base station or the first device may provide suggested third configuration information in the handover command.

[0677] Step 45: The target UE performs second perception.

[0678] Specifically, the follow-up processing falls into the following two categories:

[0679] Scenario 1: If a soft handover method is used, the target UE configures the perception parameters based on at least one of the first request information, the second request information, the second configuration information, or the third configuration information, and performs the second perception.
