[0043] It should be noted that the sensing categories shown in Table 1 above are only for illustrative purposes, and the embodiments of the present application do not limit the categories of sensing measurements.

[0044] In addition, the embodiments of the present application can be applied to the communication-sensing integrated scenario. Among them, communication-sensing integration refers to the integrated design of communication and sensing functions through spectrum sharing and hardware sharing in the same system. While the system is transmitting information, it can sense information such as orientation, distance, and speed, detect, track, and identify a target device or event.

[0046] In the embodiments of the present application, according to the different sensing signal sending nodes and receiving nodes, it may include but is not limited to Figure 2 the 6 sensing links shown. It should be noted that Figure 2 each sensing link in is illustrated with a sending node and a receiving node. In an actual system, different sensing links can be selected according to different sensing requirements. Each sensing link may have one or more sending nodes and receiving nodes, and the actual sensing system may include multiple different sensing links. And Figure 2 the sensing targets in use people and vehicles as examples, and it is assumed that neither people nor vehicles carry or install signal transceiver devices. The sensing targets in the actual scenario will be more diverse.

[0052] Sensing link 6: Sidelink sensing between terminals. For example, terminal 2 receives the sensing signal sent by terminal 1 to obtain the sensing result, or terminal 1 receives the sensing signal sent by terminal 2 to obtain the sensing result.

[0053] In some embodiments, the signaling transmission between the radio access network device and the terminal, and between different terminals can be through Radio Resource Control (RRC) signaling, or Medium Access Control Control Element (MAC CE), or layer 1 signaling, or other newly defined sensing signaling; the signaling transmission between the sensing network function and the terminal can be through Non-Access-Stratum (NAS) signaling (forwarded by the AMF), or through RRC signaling, or MAC CE, or layer 1 signaling, or other newly defined sensing signaling; the interaction between the sensing network function and the base station can be that the AMF forwards it to the radio access network through the N2 interface; or the core network sensing network function sends it to the UPF, and the UPF sends it to the radio access network through the N3 interface; or it is sent to the radio access network (such as the base station) through a newly defined interface; the signaling transmission between radio access network devices can be through the Xn interface.

[0054] In some embodiments, the sensing network function can also be called a sensing network element or a Sensing Management Function (Sensing MF). It can be on the RAN side or the core network side. It refers to a network node in the core network or RAN that is responsible for at least one of the functions such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. It can be an upgrade based on the AMF or LMF in the mobile communication network, or other network nodes or newly defined network nodes. Specifically, the functional characteristics of the sensing network function / sensing network element can include at least one of the following:

[0055] Perform target information interaction with a wireless signal transmitting device or a wireless signal measuring device (including the target terminal, or the serving base station of the target terminal, or a base station associated with the target area), where the target information includes a sensing processing request, sensing capabilities, sensing auxiliary data, types of sensing measurement quantities, sensing resource configuration information, etc., to obtain the value of the target sensing result or sensing measurement quantity (uplink measurement quantity or downlink measurement quantity) transmitted by the wireless signal measuring device; where the wireless signal can also be referred to as a sensing signal.

[0056] Determine the sensing method to be used based on factors such as the type of sensing service, information of the sensing service consumer, required sensing Quality of Service (QoS) requirement information, sensing capabilities of the wireless signal transmitting device, sensing capabilities of the wireless signal measuring device, etc. The sensing method may include: wireless access network device A transmits and wireless access network device B receives, or wireless access network device transmits and terminal receives, or wireless access network device A transmits and receives by itself, or terminal transmits and wireless access network device receives, or terminal transmits and receives by itself, or terminal A transmits and terminal B receives, etc.

[0059] Perform data processing on the value of the sensing measurement quantity, or perform calculations to obtain the sensing result. Further, verify the sensing result, estimate the sensing accuracy, etc.

[0060] The following will, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, provide a detailed description of a method and device for sending and receiving measurement configuration information and equipment provided by an embodiment of the present application.

[0061] Please refer to Figure 3 , Figure 3 which is a flowchart of a method for sending measurement configuration information provided by an embodiment of the present application. As Figure 3 shown, it includes the following steps:

[0062] Step 301, a first device obtains event information, where the event information indicates that a measurement handover trigger event is satisfied, and the measurement handover trigger event includes that the metrics related to sensing associated with the first signal satisfy the handover condition.

[0063] Wherein, the above-mentioned first device may be a terminal, a wireless access network device, or a core network element.

[0064] The event information obtained by the first device above can be the event information sent by other devices to the first device. For example, the event information sent by the receiving device of the first signal to the first device, or the first device obtains the above event information through measurement.

[0065] For example, the event information obtained by the first device above includes one of the following:

[0066] The first device measures the first signal to obtain the event information;

[0067] The first device receives the event information.

[0068] Among them, the first signal above can be a signal sent by the first device, the first device sends and receives by itself, or the first device sends the first signal, the second device measures the first signal, and feeds back the above event information to the first device.

[0069] Alternatively, the first signal is sent by other devices, and the first device measures the first signal to obtain event information.

[0070] In the embodiments of the present application, the first signal above can be a dedicated signal for sensing services, or a communication signal, such as a reference signal or a synchronization signal, etc.

[0071] Among them, the dedicated signal for sensing services can be a sensing signal generated based on a chirp or a frequency-modulated continuous wave (FMCW) signal, or a sensing signal generated based on a pseudo-random (PN) sequence or a ZC sequence, etc.;

[0072] Among them, the reference signal can be a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), or a positioning reference signal (PRS), etc.;

[0073] The above synchronization signal can be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS), etc.

[0074] The above signal carrying communication data may be a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Shared Channel (PUSCH), a Physical Downlink Control Channel (PDCCH), a Physical Uplink Control Channel (PUCCH), etc.

[0075] The above measurement handover trigger event indicates that this event is used to trigger measurement handover, such as awareness handover (or called awareness measurement handover).

[0076] Among them, the awareness-related metrics associated with the above first signal may be awareness-related metrics obtained through the measurement process based on the above first signal, or awareness-related metrics obtained during the reception of the above first signal.

[0077] The above awareness-related metrics refer to awareness-associated metrics, such as metrics affected by awareness targets or metrics affecting awareness measurements, etc.

[0078] The above metrics meeting the handover condition may be agreed upon by the protocol or the network-side device, or determined by the device generating the above event information itself. For example: the awareness-related metrics reach a preset threshold, such as the awareness-related metrics being less than the preset threshold, or the awareness-related metrics belonging to the range of the preset threshold, or the awareness-related metrics indicating a deterioration in awareness performance, or the awareness-related metrics indicating an inability to meet awareness requirements, etc. Or it may be that the awareness-related metrics obtained from consecutive multiple measurements meet the above handover condition.

[0079] Since the measurement handover trigger event includes the awareness-related metrics associated with the first signal meeting the handover condition, it is possible to trigger handover measurement when the awareness-related metrics associated with the first signal meet the handover condition, so as to improve measurement performance.

[0080] Step 302: The first device sends handover measurement configuration information to the second device.

[0081] Among them, step 302 is specifically that, in the case of receiving the above event information (i.e., meeting the measurement handover trigger event), the first device sends handover measurement configuration information to the second device, or in response to the above event information, the first device sends handover measurement configuration information to the second device.

[0082] The above handover measurement configuration information is used to configure relevant handover measurements, such as configuring measurement objects, measurement identifiers, measurement contents, and other information. Among them, handover measurement refers to a measurement carried out for handover measurement to trigger handover measurement, such as perception handover. In this way, the above handover measurement configuration information can trigger handover measurement, such as triggering perception handover.

[0083] In some embodiments, the above handover measurement configuration information can also be used to indicate handover measurement, such as indicating perception handover, or sending a command indicating handover measurement after sending the handover measurement configuration information, such as a handover command for perception handover.

[0084] In the embodiments of the present application, the above steps can be used to transfer handover measurement configuration information between devices when a handover measurement trigger event is satisfied, so that the devices support handover measurement, thereby improving the perception measurement performance of the devices.

[0085] In the embodiments of the present application, handover measurement can be perception handover, so that the device can support perception handover, thereby ensuring the continuity of perception services for moving targets and improving the perception handover performance. For example, due to the mobility of the perception target or the perception device or changes in other environmental conditions, the perception link is switched.

[0086] In some embodiments, the second device performs handover measurement behavior after receiving the above handover measurement configuration information.

[0087] Among them, the above execution of handover measurement behavior may include at least one of the following:

[0088] Performing handover measurement based on the second signal;

[0089] Performing handover measurement based on the third signal;

[0090] Sending a fourth signal, where the fourth signal is a measurement signal for handover measurement;

[0091] Among them, the second signal is from the same device as the sending device of the first signal, and the second signal can be the same or different from the first signal.

[0092] The above third signal is a signal sent by the second device and measured by the second device, that is, a signal sent and received by the second device itself.

[0093] The above fourth signal is a signal sent by the second device. The fourth signal can be processed by the sending device of the above first signal, or measured by the above first device.

[0094] In the above embodiments, multiple handover measurements are supported to improve the flexibility of handover measurement.

[0095] As an alternative implementation, the perception-related metrics include at least one of the following:

[0096] Perception metrics related to received power;

[0097] Perception metrics related to interference or noise power;

[0098] Perception metrics related to received power and also related to interference or noise power.

[0099] Among them, the perception metrics related to the above-mentioned received power may include at least one of the following:

[0100] Perception metrics related to the received power of the first signal, perception metrics related to the received power of the signal path of the first signal associated with the perception target. For example: The above-mentioned perception metrics related to received power may include: a first metric, and the first metric is used to indicate the received power of the signal path of the first signal associated with the perception target.

[0101] Among them, the signal path associated with the above-mentioned perception target may be a signal path affected by the perception target or a signal path passing through the perception target.

[0102] In the above-mentioned alternative implementation, since the perception-related metrics include perception metrics related to received power, it is possible to trigger measurement switching based on received power, making the measurement switching more reliable. In addition, it is also possible to trigger measurement switching through the received power of the signal path associated with the perception target, and the received power of the signal path associated with the perception target can more intuitively reflect whether the measurement needs to be switched. Therefore, the above-mentioned first metric can make the measurement switching more reliable.

[0103] In some implementations, the above-mentioned first metric may be the linear average value (in units of W) of the received power of the signal path associated with the perception target in the channel response obtained by measuring the first signal on the resource unit carrying the first signal. The resource unit is a time-domain or frequency-domain resource unit. In this way, the received power can be made more accurate and reliable through the linear average value. It should be noted that the embodiments of the present application do not limit the received power to the linear average value. For example: In some implementations, it may also be the median received power, the lowest received power, or the highest received power.

[0104] The above-mentioned perception metrics related to interference or noise power may refer to that the perception metric is associated with at least one of interference and noise, such as a perception metric associated with interference power, a perception metric associated with noise power, and an interference metric associated with both interference and noise power.

[0105] In one of the above - mentioned optional embodiments, since the perception - related metrics include perception metrics related to interference or noise power, it is possible to consider interference or noise when determining measurement handover, making the measurement handover more reliable.

[0106] Optionally, the perception metrics related to interference or noise power include at least one of the following:

[0107] A second metric, where the second metric is the sum of the linear average of the power of other signal paths except the signal path associated with the perception target in the channel response of the first signal on the target resource and the linear average of the interference or noise power of other signals except the first signal on the first resource; or, the second metric is equal to the difference between the total received power and the first metric, where the total received power is the total received power of the first device on the target resource;

[0108] A third metric, where the third metric is the linear average of the interference or noise power of other signals except the first signal on the second resource, or, the third metric is equal to the difference between the total received power and the received power of the first signal, where the total received power is the total received power of the first device on the target resource;

[0109] A fourth metric, where the fourth metric is the linear average of the power of other signal paths except the signal path associated with the perception target in the channel response of the first signal on the target resource; or, the fourth metric is equal to the difference between the received power of the first signal and the first metric;

[0110] Among them, the first metric is used to indicate the received power of the signal path of the first signal associated with the perception target, the target resource is the transmission resource of the first signal, the first resource includes the target resource or at least one resource other than the target resource, and the second resource includes the target resource or at least one resource other than the target resource.

[0111] The above - mentioned other signal paths may be all or part of the signal paths of the first signal except the signal path associated with the above - mentioned perception target.

[0112] The above - mentioned other signals except the first signal may refer to all or part of the signals detected by the first device on the first resource except the first signal.

[0113] The above - mentioned first resource includes the target resource or at least one resource other than the target resource, which means that the first resource includes at least one of the following:

[0114] The target resource, at least one resource other than the target resource.

[0115] The above-mentioned second resource includes the target resource or at least one resource other than the target resource, which means that the second resource includes at least one of the following:

[0116] The target resource, at least one resource other than the target resource.

[0117] Among them, the at least one resource other than the target resource can refer to at least one resource other than the target resource among the resources that the first device needs to detect or receive signals, such as resources configured by high-layer signaling or resources that the first device has predetermined to need to detect or receive signals.

[0118] The above-mentioned interference or noise power includes the sum of the interference power and the noise power, the interference power, or the noise power.

[0119] The total received power of the first device on the target resource may include the received power of signals from serving cells and non-serving cells on the target resource, adjacent-channel interference power, and thermal noise power, etc. And the above total received power may also be the linear average value (unit: W) of the total received power of the first device on the target resource.

[0120] The power corresponding to the Received Signal Strength Indication (RSSI) of the first device on the first resource may be that the total received power = RSSI * K1, where K1 is a coefficient, and K1 may specifically be agreed upon by the protocol or configured by the network side. In some embodiments, the power corresponding to the above RSSI may also be RSSI, that is, the total received power = RSSI.

[0121] The received power of the above first signal refers to the Reference Signal Received Power (RSRP) of the first signal.

[0122] The above second metric is equal to the difference between the total received power and the first metric, which can be expressed as the second metric = total received power - first metric.

[0123] The above third metric is equal to the difference between the total received power and the received power of the first signal, which can be expressed as the third metric = total received power - received power of the first signal.

[0124] The above fourth metric is equal to the difference between the received power of the first signal and the first metric, which can be expressed as the fourth metric = received power of the first signal - first metric.

[0125] In the above embodiments, by means of the above second metric, when determining measurement handover, interference or noise from other signal paths other than the signal paths associated with the sensing target and other signals other than the first signal can be considered, so that the measurement handover can be made more reliable.

[0126] In the above embodiments, by means of the above third metric, when determining measurement handover, interference or noise from other signals other than the first signal can be considered, so that the measurement handover can be made more reliable.

[0127] In the above embodiments, by means of the above fourth metric, when determining measurement handover, the power of other signal paths other than the signal paths associated with the sensing target can be considered, so that the measurement handover can be made more reliable.

[0128] The sensing metric related to the received power and also related to the interference or noise power means that the sensing metric is related to both the received power and the interference or noise power.

[0129] In an optional embodiment above, since the sensing-related metrics include sensing metrics related to the received power and also related to the interference or noise power, it is possible to consider the received power and the interference or noise when determining measurement handover, so that the measurement handover is more reliable.

[0130] In some embodiments, the sensing metric related to the received power and also related to the interference or noise power includes at least one of the following:

[0131] A fifth metric, where the fifth metric is the quotient obtained by dividing the first metric by the second metric;

[0132] A sixth metric, where the sixth metric is the quotient obtained by dividing the first metric by the third metric;

[0133] A seventh metric, where the seventh metric is the quotient obtained by dividing the first metric by the fourth metric;

[0134] An eighth metric, where the eighth metric is the product of the quotient obtained by dividing the first metric by the total received power and the target coefficient;

[0135] Wherein, the first metric is used to indicate the received power of the signal path associated with the sensing target of the first signal, and the total received power is the total received power of the first device on the target resource.

[0136] Among them, for the above-mentioned first index, second index, third index, and fourth index, refer to the above-mentioned embodiments, and details are not described here. It should be noted that in the case of including at least one of the above-mentioned fifth index, sixth index, seventh index, and eighth index, the perception-related index in the embodiment of the present application may or may not include the above-mentioned first index, second index, third index, and fourth index.

[0137] The above target coefficient can be expressed as K2. For example, the eighth index = K2 * the first index / the total received power, where K2 is a coefficient, and K2 can specifically be agreed upon by the protocol or configured by the network side.

[0138] In this embodiment, through the above-mentioned fifth index, sixth index, seventh index, or eighth index, it is possible to consider the received power and interference or noise when determining the measurement handover, so as to make the measurement handover more reliable.

[0139] In some embodiments, the perception index related to the received power and also related to the interference or noise power may further include at least one of the following:

[0140] Perception SINR-related index, perception SNR-related index, perception signal interference ratio (Signal Interference Ratio, SIR)-related index, perception RSRQ-related index.

[0141] As an alternative embodiment, the signal path associated with the perception target satisfies at least one of the following:

[0142] The parameter satisfies the first preset threshold, or the parameter is within the first preset interval range;

[0143] The parameter satisfies the preset modulation rule;

[0144] The parameter difference from the first-arrival signal path satisfies the second preset threshold, or the parameter difference from the first-arrival signal path is within the second preset interval range;

[0145] The parameter difference from the reference signal path satisfies the third preset threshold, or the parameter difference from the reference signal path is within the third preset interval range.

[0146] Among them, the above parameters may include at least one of the following:

[0147] Amplitude, power, intensity, energy, phase, Doppler, time delay, angle;

[0148] The above parameter difference may include at least one of the following:

[0149] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, time delay difference, angle difference.

[0150] The first preset threshold, the first preset interval range, the second preset threshold, the second preset interval range, the third preset threshold, and the third preset interval range can be agreed upon in the protocol or configured by the network side. Alternatively, these preset thresholds or preset interval ranges are determined by the receiving device according to the perceived prior information or perceived requirements. That the above parameters meet the first preset threshold can mean that the parameters exceed or are equal to the first preset threshold. That the parameter difference from the first-arrival signal path meets the second preset threshold can mean that the parameter difference from the first-arrival signal path exceeds or is equal to the second preset threshold. That the parameter difference from the reference signal path meets the third preset threshold can mean that the parameter difference from the reference signal path exceeds or is equal to the third preset threshold.

[0151] For example: If the sensing service is moving target detection, then it is necessary to detect the signal paths with Doppler greater than zero as the signal paths associated with the sensing target; or for the traffic scene where the sensing target is a vehicle and the default vehicle speed is 40 km / h to 120 km / h, then detect the signal paths within the corresponding speed range (Doppler range) as the signal paths associated with the sensing target; or the distance between the sensing target area and the sensing signal transceiver needs to meet specific requirements, then detect the signal paths within the corresponding time delay range as the signal paths associated with the sensing target; or if the sensing service is respiration monitoring, then the corresponding normal respiration rate can be judged according to the gender and age of the person (for example, 15 to 30 times per minute, which can be used as the perceived prior information, and the corresponding Doppler range, 0.25 to 0.5 Hz, can be calculated).

[0152] The above first-arrival signal path can be a line-of-sight (LOS) path, specifically the signal path that arrives at the receiving end first in the first signal. The above reference signal path can be the signal path reflected by a known target, such as the signal path reflected by a reconfigurable intelligent surface (RIS), backscatter, or other known passive targets.

[0153] The above preset modulation rules can be agreed upon in the protocol or configured by the network side. The specific modulation rules are the modulation rules of tags or backscatter devices or RISs, that is, the signal paths associated with the sensing target can be the signal paths modulated and reflected by tags or backscatter devices or RISs.

[0154] In the above optional implementation manner, the signal paths associated with the sensing target can be determined in multiple ways, which can not only improve the flexibility of determining the signal paths associated with the sensing target, but also jointly determine based on multiple ways to improve the accuracy of determining the signal paths associated with the sensing target.

[0155] In some embodiments, before determining the signal paths associated with the sensing target, a set of signal paths can also be determined. The set of signal paths includes signal paths whose amplitude, power, intensity, or energy exceeds a certain threshold. As Figure 4 shown, the set of signal paths includes signal paths 0, 1, 2, and 3. Then, based on at least one of the above, the signal paths associated with the sensing target are determined in the set of signal paths to reduce the computational amount.

[0156] The following uses an embodiment to illustrate the calculation of the indicators in the embodiments of the present application. It should be noted that the calculation of each indicator in the embodiments of the present application is not limited, and the following embodiments are only for illustration.

[0157] The first device (such as a terminal) performs channel estimation based on the transmitted first signal X(k) and the received signal Y(k) corresponding to the first signal to obtain the channel response H(k) = Y(k) / X(k), where k = 0, 1, 2,..., K - 1 represents the resource unit index, and K is the number of resource units. After the first device obtains the channel response H(k), it transforms it to the first dimension and determines the signal paths associated with the sensing target in the first dimension. Then, the power of the signal paths associated with the sensing target is calculated as the first indicator. If the signal paths associated with the sensing target include multiple signal paths, the sum of the powers of the multiple signal paths is calculated as the first indicator.

[0158] Among them, the first dimension includes one of the following:

[0159] Time delay dimension;

[0160] Doppler dimension;

[0161] Azimuth angle dimension;

[0162] Elevation angle dimension;

[0163] A dimension that combines at least two of the time delay dimension, Doppler dimension, azimuth angle dimension, and elevation angle dimension. For example, time delay-Doppler dimension, time delay-Doppler-angle dimension, etc.;

[0164] For example, if H(f) is the channel response, where f = 0, 1, 2, ..., N - 1 represents the frequency-domain sampling points (e.g., subcarrier indices), then by performing an inverse Fourier transform on H(f), it can be transformed into the delay dimension (the first dimension); for another example, if H(f, t) is the channel response, where f = 0, 1, 2, ..., N - 1 represents the frequency-domain sampling points (e.g., subcarrier indices) and t = 0, 1, 2, ..., M - 1 represents the time-domain sampling points (e.g., OFDM symbol indices), then by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension on H(f, t), it can be transformed into the delay-Doppler dimension (the first dimension); for yet another example, if H(f, t, s) is the channel response, where f = 0, 1, 2, ..., N - 1 represents the frequency-domain sampling points (e.g., subcarrier indices), t = 0, 1, 2, ..., M - 1 represents the time-domain sampling points (e.g., OFDM symbol indices), and s = 0, 1, 2, ..., P - 1 represents the spatial domain sampling points (antenna indices or port indices), then by performing an inverse Fourier transform along the frequency domain dimension, a Fourier transform along the time domain dimension, and a Fourier transform along the antenna domain dimension on H(f, t, s), it can be transformed into the delay-Doppler-angle dimension (the first dimension).

[0165] Method for determining the signal paths (simply referred to as sensing paths) associated with the sensing target in the channel response measured for the first signal:

[0166] Determine the set of signal paths. The signal paths in the set of signal paths include the paths whose amplitude, power, intensity, or energy exceeds a certain threshold among all the paths after the channel response is transformed into the first dimension. For example Figure 4 in, signal paths 0, 1, 2, 3 are the paths in the set of signal paths; the certain threshold can be set to be higher than the noise threshold or higher than the noise interference threshold, or as agreed upon by the protocol. Among them, this step (determining the set of signal paths) is optional, and the signal paths associated with the sensing target can be determined only according to the next step.

[0167] Select the signal paths that meet the first condition from the set of signal paths or from all the signal paths of the first signal as the signal paths associated with the sensing target. The first condition includes at least one of the following:

[0168] The amplitude, power, intensity, or energy of the signal path exceeds a preset threshold or is within a preset interval range, such as the preset threshold is 5 times higher than the noise threshold;

[0169] The Doppler of the signal path exceeds a preset threshold or is within a preset interval range;

[0170] The delay of the signal path exceeds a preset threshold or is within a preset interval range;

[0171] The angle of the signal path exceeds a preset threshold or is within a preset interval range;

[0172] The difference in amplitude / power / intensity / energy between the signal path and the first-arrival path (e.g., the LOS path) or the reference path exceeds a preset threshold or lies within a preset range, where the reference signal path can be a signal path reflected by a known target (e.g., RIS / Backscatter / other known passive targets, etc.);

[0173] The Doppler difference between the signal path and the first-arrival path (e.g., the LOS path) or the reference path exceeds a preset threshold or lies within a preset range;

[0174] The time-delay difference between the signal path and the first-arrival path (e.g., the LOS path) or the reference path exceeds a preset threshold or lies within a preset range;

[0175] The angle difference between the path and the first-arrival path (e.g., the LOS path) or the reference path exceeds a preset threshold or lies within a preset range;

[0176] The amplitude, power, intensity, energy, or phase of the path satisfies a specific modulation rule, and the specific modulation rule is the modulation rule of the Tag / Backscatter device or RIS, that is, the path associated with the sensed target can be a signal path modulated and reflected by the Tag / Backscatter device or RIS

[0177] Among them, the above first conditions can also be based on the results of statistics over a period of time; for example, the proportion of the above indicators (e.g., the Doppler of the path, the time delay of the path, etc.) exceeding the preset threshold or lying within the preset range reaches a preset proportion within a preset time window, or the number of times the above indicators (e.g., the Doppler of the path, the time delay of the path, etc.) exceed the preset threshold or lie within the preset range reaches a preset number within a preset time window;

[0178] Among them, the preset threshold or the set range is sent by other devices to the receiving device and determined by other devices according to the sensed prior information or sensing requirements. Or, the preset threshold or the preset range can be an agreement in the protocol, or the preset threshold or the preset range is determined by the receiving device according to the sensed prior information or sensing requirements.

[0179] Among them, the sensed prior information or sensing requirements include the following information:

[0180] Perception service or perception service type. The perception service can be, for example, detecting the presence of a target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, radar cross section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading, gait recognition, facial expression recognition, facial recognition, breathing monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environment reconstruction, terrain and landform, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density / vehicle density detection, etc. The perception service type can classify multiple different perception services according to certain characteristics. For example, it can be classified into detection-type perception services (such as intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (action recognition, identity recognition), etc. according to function. It can also be classified according to the perception range (close-range perception, medium-range perception, long-range perception), according to the perception fineness (coarse-grained perception, fine-grained perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc. If the perception service is breathing monitoring, the corresponding normal breathing frequency can be judged according to the gender and age of a person (for example, male: 13 - 21 times per minute, female: 15 - 20 times per minute; adult: 12 - 20 times per minute, child: about 30 - 40 times per minute), which can be used as perception prior information.

[0181] Perception target area: It refers to the position area of the perception object, or the position area where imaging or environment reconstruction needs to be performed. For example, determine the preset interval range of the time delay of the signal path associated with the perception target according to the approximate position / distance of the perception object.

[0182] Perception object type: Classify the perception object according to its possible motion characteristics. Each perception object type contains information such as the motion speed range, motion acceleration range, and typical RCS range of typical perception objects.

[0183] The number of perception targets; for example, the perception result of a camera can be used as a kind of perception prior information to obtain the number of perception targets.

[0184] For example Figure 4 In, signal paths 0, 1, 2, 3 are the paths in the signal path set, where signal paths 2, 3 are the perception paths that meet the first condition (for example, their time delays meet the preset threshold), and paths 0, 1 are the paths associated with other scatterers.

[0185] Among them Figure 4In it, a schematic diagram of multi-signal paths in the first dimension (delay dimension, Doppler dimension, azimuth dimension, or elevation dimension) of the channel response, where the horizontal axis is the first dimension and the vertical axis is the normalized amplitude, power, intensity, or energy.

[0186] For frequency range 1, the reference point of the first indicator can be the antenna connector of a receiving device such as a terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first indicator measured and reported by the receiving device shall not be lower than the indicator of any single receiving channel. For frequency range 2, the first indicator measured by a certain receiving channel needs to be obtained by measuring the combined signals on multiple antenna elements corresponding to this receiving channel.

[0187] Calculation method 2 of the first indicator:

[0188] When calculating the received power of the signal paths associated with the sensing target, it can also be the difference between the power of the signal paths associated with the sensing target in the first dimension and as the first indicator, where N 1 represents the number of signal paths associated with the sensing target. is the average power of multiple signal paths outside the signal path set in the first dimension.

[0189] Calculation method of the received power of the first signal:

[0190] The received power of the first signal can be that after the receiving device obtains the channel response H(k), it transforms it into the first dimension, determines the signal path set in the first dimension, and then calculates the sum of the powers of all signal paths in the signal path set.

[0191] Calculation method 2 of the received power of the first signal:

[0192] The received power of the first signal can also be the difference between the sum of the powers of all signal paths in the signal path set in the first dimension and where N 2 represents the number of signal paths in the signal path set.

[0193] Calculation method of the total received power:

[0194] Total received power

[0195] where Y(k) is the received signal corresponding to the first signal, k = 0, 1, 2,..., K - 1 represents the resource unit index, and K is the number of resource units.

[0196] Calculation method of the second indicator:

[0197] The channel response H(k) is subjected to a first filtering process to obtain H filter1 (k), and then based on H filter1 (k) and the first signal X(k), the received signal Y filter1 (k) after the first filtering process is calculated, that is, Y filter1 (k) = H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter1 (k) after the first filtering process to obtain the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then the second indicator is calculated:

[0198]

[0199] Among them, the first filtering process is used to eliminate the noise and interference in the first dimension and the paths not associated with the perceived target. For example, the first filtering process sets Figure 4 the amplitudes, powers, intensities, or energies of the other paths except the signal paths associated with the perceived target in filter1 to zero. The channel response H

[0200] Calculation method of the third indicator:

[0201] The channel response H(k) is subjected to a second filtering process to obtain H filter2 (k), and then based on H filter2 (k) and the first signal X(k), the received signal Y filter2 (k) after the second filtering process is calculated, that is, Y filter2 (k) = H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter2 (k) after the second filtering process to obtain the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then the third indicator is calculated:

[0202]

[0203] The above second filtering process can be a noise interference suppression process in the first dimension (for example Figure 4(set the amplitude, power, intensity, or energy of other paths except the signal path set to zero), or minimum mean squared error (MMSE) filtering. The channel response H filter2 (k) does not contain noise and interference, but only contains the paths in the signal path set.

[0204] Calculation method 2 of the third indicator:

[0205] According to the average power of multiple signal paths outside the signal path set in the first dimension calculate the third indicator P σ2 , that is where N represents the number of sampling points in the first dimension.

[0206] It should be noted that if the receiving device determines multiple sensing targets, or the receiving device obtains the number of sensing targets according to sensing prior information or sensing requirements, there are the following methods:

[0207] Method 1: Calculate the sensing-related indicators (which can also be called target indicators) for each sensing target respectively. For example, in Figure 4 , determine the signal paths associated with each sensing target respectively, and then calculate the respective sensing-related indicators corresponding to each sensing target; at this time, when calculating the second indicator corresponding to a certain sensing target (such as sensing target A), there are two methods: that is: the second indicator of sensing target A = total received power - the first indicator of sensing target A; or, the second indicator of sensing target A = total received power - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing targets in total: A and B); similarly, there are also two calculation methods for the fourth indicator: the fourth indicator of sensing target A = RSRP of the first signal - the first indicator of sensing target A; or, the fourth indicator of sensing target A = RSRP of the first signal - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing targets in total: A and B)

[0208] Method 2: Calculate a sensing-related indicator for multiple sensing targets. For example, in Figure 4 , determine the signal paths associated with any sensing target, and then determine all these signal paths as the signal paths associated with the sensing target; it is equivalent to regarding multiple sensing targets as a virtual sensing target, and then calculate the sensing-related indicator corresponding to this virtual sensing target.

[0209] It should be noted that the above calculation methods are only examples, and the embodiments of the present application do not limit the specific calculation methods of the indicators.

[0266] Through the above measurement content information, the accuracy of handover measurement can be improved.

[0267] The above measurement event information is used to indicate the events that need to be determined during handover measurement or the event information that needs to be reported in the measurement report.

[0268] In some embodiments, the above measurement event information is used to indicate at least one of the following events:

[0269] The perception-related metrics associated with the second signal meet the first metric condition, the perception-related metrics associated with the third signal meet the second metric condition, the perception measurement quantity of the second signal meets the first measurement quantity condition, the perception measurement quantity of the third signal meets the second measurement quantity condition;

[0270] Wherein, the second signal is from the same transmitting device as the first signal, and the third signal is a signal transmitted by the second device and measured by the second device.

[0271] Wherein, the above first metric condition, second metric condition, first measurement quantity condition or second measurement quantity condition can be protocol-agreed or network-side configured.

[0272] The condition that the perception-related metric associated with the second signal satisfies the first metric condition can be that the perception-related metric associated with the second signal exceeds a preset threshold, or that the perception-related metric associated with the second signal is better than the perception-related metric associated with the first signal; the condition that the perception-related metric associated with the third signal satisfies the second metric condition can be that the perception-related metric associated with the third signal exceeds a preset threshold, or that the perception-related metric associated with the third signal is better than the perception-related metric associated with the first signal; for example: the received power of the signal path associated with the perception target measured based on the second signal or the metric related to the perception SINR / SNR / SIR / RSRQ exceeds a preset threshold. Among them, the above preset threshold can be agreed upon by the protocol or configured by the network side, or can be associated with the value of at least one metric obtained by measuring the first signal. For example, if the received power of the signal path associated with the perception target obtained based on the first signal is P1, then the preset threshold value is α*P1, where α is a scaling factor.

[0273] The condition that the perception measurement quantity of the second signal satisfies the first measurement quantity condition can be that the perception measurement quantity of the second signal exceeds a preset threshold, or that the perception measurement quantity of the second signal is better than the perception measurement quantity of the first signal; the condition that the perception measurement quantity of the third signal satisfies the second measurement quantity condition can be that the perception measurement quantity of the third signal exceeds a preset threshold, or that the perception measurement quantity of the third signal is better than the perception measurement quantity of the first signal. For example, the distance d1 from the first device to the perception target measured based on the second signal ≥ α* the distance d2 from the perception target to the second device, where α is a scaling factor; or d1 - d2 exceeds a preset threshold; or the distance d3 from the perception target to the second device measured based on the third signal is lower than a preset threshold.

[0274] Through the above measurement event information, the device can accurately determine the event to be discriminated, so as to reduce the complexity of handover measurement.

[0275] The above measurement assistance information is information for assisting handover measurement. For example, it includes at least one of the following:

[0276] The position information of the perception target, or the direction information relative to the second device, which is used to help the candidate target device adjust the spatial domain filter / spatial domain filter coefficient (the received beam) when receiving the second signal, or adjust the spatial domain filter / spatial domain filter coefficient when transmitting and receiving the third signal, or adjust the spatial domain filter coefficient when transmitting the fourth signal;

[0277] The position information of the first device, or the direction information of the first device relative to the candidate target device, or the distance information between the first device and the second device

[0278] Suggested transmission configuration or reception configuration, such as whether to use omnidirectional transmission or reception, or the transmission or reception beam index used, etc.

[0279] The complexity of the handover measurement of the second device can be reduced by the above auxiliary information.

[0280] It should be noted that some or all of the at least one item included in the above handover measurement configuration information can also be protocol-agreed or pre-configured.

[0281] As an alternative implementation, the method further includes:

[0282] The first device obtains a handover measurement report of a second signal, a third signal, or a fourth signal. The second signal has the same transmission device as the first signal. The third signal is a signal sent by the second device and measured by the second device. The fourth signal is a signal sent by the second device;

[0283] In the case where it is determined based on the measurement report that a measurement handover occurs, the first device sends a handover command to the second device. The handover command is used to indicate that the measurement of the sensing target will be switched to the second device.

[0284] Among them, obtaining the measurement report of the second signal or the third signal can be that the first device receives the feedback from the second device. For example, the second device performs a handover measurement, obtains the above measurement report, and sends it to the first device. Or, the handover measurement report of the fourth signal can be that the first device performs a handover measurement on the above fourth signal to obtain the above measurement report, or the receiving device of the first signal performs a measurement and sends the handover measurement report to the first device.

[0285] The above handover measurement report is a measurement report obtained by performing a handover measurement. For example, it can include at least one of the following:

[0286] Measurement results of sensing measurement quantities, sensing-related metrics, communication-related metrics, measurement event information,

[0287] Determining the measurement handover based on the measurement report above can be that the first device decides on the measurement handover based on the above handover measurement report. For example, the above handover measurement report indicates that the second device performing the sensing measurement is better than the above source node performing the sensing measurement, or the above handover measurement report indicates that the measurement result of the second device meets a preset condition, such as the signal quality being higher than a preset threshold, or, the above handover measurement report indicates that the distance between the second device and the sensing target is within a preset range, etc.

[0288] The above switching command can switch the signal sending device for measuring the sensing target to the above second device, or switch the signal receiving device for measuring the sensing target to the above second device. And the above switching command can switch at least one of the signal sending device or the signal receiving device for measuring the sensing target. For example, switch the signal sending device and the signal receiving device, or only switch the signal sending device, or only switch the signal receiving device. Among them, when switching the signal sending device and the signal receiving device, the switching command is sent to these two devices respectively.

[0289] In one optional implementation manner above, by sending a switching command to the second device, the measurement of the sensing target is switched to the second device, so as to improve the sensing performance.

[0290] It should be noted that in the embodiments of the present application, there is no limitation on sending the above switching command based on the above switching measurement report. For example: The switching command can also be sent without obtaining the switching measurement report. For example: The first device directly sends the switching command based on the above event information, and specific details are not limited thereto.

[0291] As an optional implementation manner, the first device includes at least one of the following: the sending device of the first signal, the receiving device of the first signal, and the sensing network function;

[0292] The second device includes at least one of the following: the signal sending candidate device for switching measurement, the signal receiving candidate device for switching measurement.

[0293] Among them, the above signal sending candidate device for switching measurement means that this device may send signals before and after switching. And if the requirements are not met during the switching measurement, it will not be used as the final switching target device. If the switching measurement meets the requirements, it will be switched to this device.

[0294] The above signal receiving candidate device for switching measurement means that this device may receive signals before and after switching. And if the requirements are not met during the switching measurement, it will not be used as the final switching target device. If the switching measurement meets the requirements, it will be switched to this device.

[0295] In some implementation manners, the second device may include one or more signal sending candidate devices or signal receiving candidate devices.

[0296] In one optional implementation manner above, the switching of the signal sending device during measurement or the switching of the signal receiving device can be realized, or the switching of both the signal sending device and the signal sending device can be realized, so as to improve the flexibility of measurement switching and meet more scenario or service requirements.

[0297] For sensing, the devices on both sides of sensing can be such that one side is a radio access network device and the other side is a terminal, or the devices on both sides of sensing are both base stations, or both are terminals. It can be that the sensing signal receiving device switches, or the sensing signal transmitting device switches, or both the sensing signal receiving and transmitting devices switch.

[0298] In an embodiment of the present application, a first device obtains event information, where the event information indicates that a measurement handover trigger event is satisfied, and the measurement handover trigger event includes that a sensing-related metric associated with a first signal satisfies a handover condition; the first device sends handover measurement configuration information to a second device. This can achieve the transfer of handover measurement configuration information between devices when the measurement handover trigger event is satisfied, so that the devices support handover measurement, thereby improving the sensing measurement performance of the devices.

[0359] It should be noted that, as the implementation manner of the second device corresponding to the embodiment shown in Figure 3 the specific implementation manner can refer to the relevant description of the embodiment shown in Figure 3 In order to avoid repeated description, this embodiment will not be elaborated here.

[0360] The method provided by the embodiments of the present application will be illustrated by multiple embodiments below:

[0361] Embodiment 1:

[0362] In this embodiment, the process in which the sensing signal transmitting device remains unchanged and the sensing signal receiving device is switched is mainly described.

[0363] In this embodiment, device A sends a sensing signal, device B receives the sensing signal and measures, then switches to device A sending the sensing signal, and device C receives the sensing signal and measures, including the following steps:

[0364] Step 1: Trigger measurement

[0365] Device A emits a first signal, device B receives the first signal and performs sensing measurement. When a measurement handover trigger event is satisfied, device A or the sensing network function (the first device) sends handover measurement configuration information to the candidate target device (the second device);

[0366] The measurement handover trigger event includes at least one of the following:

[0367] The first measurement result obtained by device B based on the first signal reaches a preset threshold. The first measurement result includes at least one of the following:

[0368] Sensing-related metrics (i.e., the values of sensing-related metrics);

[0369] Communication-related metrics (i.e., the values of communication-related metrics);

[0370] The value of the sensing measurement quantity;

[0371] Device information.

[0372] The above perception-related metrics or communication-related metrics reaching the preset threshold values can be based on the perception SINR / SNR / SIR / RSRQ-related metrics obtained from the measurement of the first signal being less than the preset value. Optionally, it can be that the perception SINR / SNR / SIR / RSRQ-related metrics obtained from consecutive multiple measurements are less than the preset value.

[0373] The value of the above perception measurement quantity reaching the preset threshold can be, for example, the distance d1 between the perception target and device B exceeding the preset value; or, the position coordinates of the perception target satisfying specific conditions, that is, being within a specific area range; or, the magnitude of the movement speed of the perception target exceeding the preset value;

[0374] The above device information includes at least one of the following:

[0375] The movement direction of the signal transmitting device / receiving device;

[0376] The magnitude of the movement speed of the signal transmitting device / receiving device;

[0377] The position information of the signal transmitting device / receiving device;

[0378] The orientation information of the signal transmitting device / receiving device;

[0379] The clock deviation information between the perception signal transmitting device and the receiving device

[0380] Or, it can be that the available perception resources of device A or device B change. For example, when other high-priority perception / communication / communication-sensing integration services occur suddenly, it is necessary to evaluate whether to initiate the perception handover process based on the remaining available perception resources.

[0381] Or, it can be that device A or device B receives a perception handover indication or an indication to stop providing perception services from the first device.

[0382] The above handover measurement configuration information includes at least one of the following:

[0383] Measurement object information, measurement report configuration, measurement identifier, measurement content information, measurement event information, measurement auxiliary information.

[0384] Among them, the measurement object information can include at least one of the following:

[0385] The configuration information of the second signal that the candidate target device needs to receive and measure.

[0386] The second signal is the signal sent by device A and received and measured by the candidate target device. In particular, the second signal and the first signal can be the same signal;

[0387] Configuration information of the third signal, where the third signal is a signal that the second device needs to send and that the second device receives and measures;

[0388] Configuration information of the fourth signal, where the fourth signal is a signal sent by the second device and received and measured by device A. Here, the fourth signal can be understood as Figure 3 a branch of the third signal in the embodiment shown;

[0389] The above measurement report configuration may include a measurement report configuration for the second signal or the third signal. For example, it may include the principle of reporting from the second device to device A or the sensing network function, which may be periodic reporting or event-triggered reporting; the type of reference signal for measurement, etc.; the measurement report format, such as the number of beams reported, etc.

[0390] Among them, the configuration information of the above second target signal includes at least one of the following:

[0391] Signal resource identifier, signal usage, waveform, subcarrier spacing, guard interval, starting frequency domain position, frequency domain resource length, frequency domain resource interval, starting time domain position, time domain resource length, time domain resource interval, time domain resource characteristics, signal power, sequence information, signal direction, Quasi Co-Location (QCL) relationship, antenna port information, cyclic prefix information.

[0392] The above signal resource identifier is used to distinguish different signal resource configurations;

[0393] The above signal usage indicates that the target signal is a signal for communication (such as channel measurement, channel estimation, synchronization, carrying data information, etc.), a signal for sensing, or a signal for both communication and sensing. Specifically, it can also be a signal for which sensing service or a signal for which type of sensing service.

[0394] Among them, the sensing service may include at least one of the following:

[0395] Detect the presence of the target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, radar cross section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, face recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environment reconstruction, terrain and landform, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc. The above-mentioned perception service types can classify multiple different perception services according to certain characteristics. For example, they can be classified into detection-type perception services (such as intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (action recognition, identity recognition), etc. according to functions. They can also be classified according to the perception range (close-range perception, medium-range perception, long-range perception), according to the perception fineness (coarse-grained perception, fine-grained perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc.

[0396] The above waveforms can be OFDM, single-carrier frequency-division multiple access (SC-FDMA), orthogonal time frequency space (OTFS), frequency-modulated continuous wave (FMCW), or pulse signals, etc.

[0397] The above subcarrier spacing can be the subcarrier spacing of an OFDM system, for example: 30 KHz.

[0398] The above guard interval can be the time interval between the end of the signal transmission time and the time when the latest echo signal of the signal is received. This parameter is proportional to the maximum perception distance. For example, it can be calculated by c / (2R max ) where R max is the maximum perception distance (belonging to the perception demand information). For example, for a self-transmitting and self-receiving perception signal, R max represents the maximum distance from the perception signal transceiver point to the signal reflection point. In some cases, the cyclic prefix (CP) of an OFDM signal can act as the minimum guard interval, and c is the speed of light.

[0399] The above-mentioned starting position in the frequency domain can be the starting frequency point, or the starting resource element (RE), or the resource block (RB) index.

[0400] The above-mentioned frequency-domain resource length can be the frequency-domain bandwidth, which is inversely proportional to the range resolution. The frequency-domain bandwidth B of each signal satisfies B≥c / (2ΔR), where c is the speed of light and ΔR is the range resolution.

[0401] The above-mentioned frequency-domain resource interval represents the interval between adjacent signal frequency-domain resource units, which can be expressed by the number of REs or RBs, or by the density value (Density). For example, Density = 1 means that there is one RE in each RB for carrying signals. The frequency-domain resource interval is inversely proportional to the maximum unambiguous range / delay. For an OFDM system, when subcarriers are continuously mapped, the frequency-domain interval is equal to the subcarrier interval.

[0402] The above-mentioned starting position in the time domain can be the starting time point, or the starting symbol, time slot, or frame index.

[0403] The above-mentioned time-domain resource length can be the burst duration, and the time-domain resource length is inversely proportional to the Doppler resolution.

[0404] The above-mentioned time-domain resource interval can be the time interval between two adjacent signal resource units, and the time-domain resource interval is associated with the maximum unambiguous Doppler shift or the maximum unambiguous speed.

[0405] The above-mentioned time-domain resource characteristics can be periodic transmission, semi-persistent transmission, or non-periodic transmission.

[0406] The above-mentioned signal power can be discrete power values. For example, values are taken every 2 dBm from -20 dBm to 23 dBm.

[0407] The above-mentioned sequence information can include sequence type information (such as ZC sequence, PN sequence, etc.), sequence generation method, or sequence length, etc.

[0408] The above-mentioned signal direction can be the angle information or beam information of signal transmission.

[0409] The above-mentioned QCL relationship can indicate that the above-mentioned signal includes multiple resources, and each resource has QCL with a synchronization signal block (SSB). QCL includes type A, type B, type C, or type D.

[0410] The above-mentioned antenna port information can be the maximum number of antenna ports and the antenna port index.

[0411] The above cyclic prefix (CP) information may include CP type or CP length, etc. Among them, the CP type may include normal cyclic prefix (NCP), extended cyclic prefix (ECP), or a newly designed CP dedicated to sensing measurement, etc.

[0412] It should be noted that in the embodiments of the present application, one or more items included in the configuration information of the above target signal may also be agreed upon by the protocol or pre-configured, and this is not limited herein.

[0413] The above measurement content information may include at least one of the following:

[0414] Indicators related to sensing or communication related to at least one item associated with the second signal or the third signal, such as the received power of the signal path associated with the sensing target measured based on the second signal or indicators related to sensing SINR / SNR / SIR / RSRQ; or the received power of the signal path associated with the sensing target obtained based on the third signal or indicators related to sensing SINR / SNR / SIR / RSRQ;

[0415] At least one sensing measurement quantity (which can be a combination of one or several items) associated with the second signal or the third signal, such as the distance d1 from device A to the sensing target or the distance d2 from the sensing target to the second device measured based on the second signal; or the difference or ratio between d1 and d2; or the bistatic distance d_bi (d_bi = d1 + d2) measured based on the second signal; or the distance d3 from the sensing target to the second device measured based on the third signal.

[0417] The value of at least one indicator related to sensing or communication related to the second signal or the third signal satisfies a preset condition. For example, the received power of the signal path associated with the sensing target measured based on the second signal or the indicator related to sensing SINR / SNR / SIR / RSRQ exceeds a preset threshold; where the preset threshold may be associated with the value of at least one indicator related to sensing or communication related to the first signal. For example, if the received power of the signal path associated with the sensing target obtained based on the first signal is P1, then the threshold value is α*P1, where α is a scaling factor;

[0418] The value of at least one sensed measurement quantity obtained based on the measurement of the second signal or the third signal satisfies a preset condition. For example, d1 ≥ α * d2 obtained based on the measurement of the second signal, where α is a scaling factor; or d1 - d2 exceeds a preset threshold; or d3 obtained based on the measurement of the third signal is lower than a preset threshold.

[0419] The measurement assistance information may include at least one of the following:

[0420] The position information of the sensed target or the direction information relative to the candidate target device (which helps the candidate target device adjust the spatial domain filter / spatial domain filter coefficient (adopted receiving beam) when receiving the second signal, or adjust the spatial domain filter / spatial domain filter coefficient when transmitting and receiving the third signal, or adjust the spatial domain filter / spatial domain filter coefficient when transmitting the fourth signal);

[0423] It should be noted that device A or the second device can judge whether the measurement event is satisfied according to the average value of multiple measurement quantities / metrics at different times (layer 1 filtering and / or layer 3 filtering), or judge that the values of the measurement quantities / metrics of continuous multiple measurements satisfy the preset conditions, so as to avoid the randomness / ping-pong effect caused by judging according to a single result;

[0424] The determination of the second device is based on the candidate target device status information (which can be sent by the second device to device A or the sensing network function, and device A or the sensing network function determines the second device according to the candidate target device status information (i.e., the candidate target device list); or device A obtains the candidate target device list from the sensing network function).

[0428] The resource information currently available for the second device to perform sensing, such as including time resources (number of symbols, number of time slots, number of frames, etc.), number of frequency resources, total bandwidth, available frequency band positions, etc.), antenna resources (number of antennas / antenna sub-arrays), phase modulation resources (number of hardware phase shifters), orthogonal code resources (orthogonal code length and quantity), etc. Among them, the frequency resources may include the number of resource blocks (RBs) and the number of resource elements (REs);

[0430] If the second device is a terminal, it also includes the status information of the terminal, such as power, moving speed, moving direction, time of staying stationary / moving, etc.

[0431] Step 2: Perform measurements

[0432] After receiving the handover measurement configuration information, the second device performs handover measurements based on the second signal or the third signal and feeds back a handover measurement report to the sensing network function or device A; the handover measurement report includes at least one of the values of the sensing measurement quantities, the values of the sensing-related metrics or communication-related metrics, and the identifier of the corresponding measurement event satisfied.

[0433] Alternatively, device A performs handover measurements based on the fourth signal sent by the second device to obtain a handover measurement report and sends it to the sensing network function.

[0434] Among them, the first signal and the second signal may be the same signal, that is, device A transmits the first signal and device B receives it and performs sensing measurements; the second device receives the first signal and performs handover measurements (when the first signal and the second signal are the same signal, that is, the configuration information of the second signal is the configuration information of the first signal); or, the second device sends the third signal and receives the echo signal of the third signal to perform handover measurements; or, the second device sends the fourth signal, and device A receives the fourth signal and performs handover measurements.

[0435] The first signal and the second signal can be different signals. That is, device A transmits the first signal, and device B receives and performs sensing measurements. When a measurement switching trigger event is satisfied, device A sends the second signal, and the second device receives the second signal and performs switching measurements; or, the second device sends a third signal and receives the echo signal of the third signal to perform switching measurements; or, the second device sends a fourth signal, and device A receives the fourth signal and performs switching measurements.

[0436] Step 3: Handover decision

[0437] Device A decides whether to initiate a handover based on the handover measurement report reported by the candidate target device or based on the measurement of the fourth signal sent by the second device.

[0438] Optionally, device A receives the handover measurement report from the second device and reports the handover measurement report to the sensing network function, and the first device decides whether to initiate a handover request; or, the sensing network function decides whether to initiate a handover based on the handover measurement report received from the second device; or, device A obtains the handover measurement report based on the measurement of the fourth signal sent by the second device and reports it to the sensing network function, and the sensing network function decides whether to initiate a handover request;

[0439] If the handover is not initiated, the subsequent processing can be to maintain or end the current sensing measurement, that is, still perform sensing measurements based on device A sending the first signal and device B receiving it, or stop the sensing measurement.

[0440] If the handover is initiated, device A or the sensing network function determines the candidate target device and sends a handover request message to it, requesting the at least one second device to perform sensing measurements.

[0441] The handover request message further includes at least one of the following information:

[0442] Sensing requirements, which can include the sensing target area / object type, required sensing functions, sensing purpose, sensing results, etc.);

[0443] Perceived Quality of Service (QoS), including at least one of the following: perceived resolution (which can be further divided into: ranging resolution, angle measurement resolution, velocity measurement resolution, imaging resolution, etc.), perceived accuracy (which can be further divided into: ranging accuracy, angle measurement accuracy, velocity measurement accuracy, positioning accuracy, etc.), perceived range (which can be further divided into: ranging range, velocity measurement range, angle measurement range, imaging range, etc.), perceived latency (the time interval from when the perceived signal is sent to when the perceived result is obtained, or the time interval from when the perceived demand is initiated to when the perceived result is obtained), perceived update rate (the time interval between two adjacent executions of perception and obtaining the perceived result), detection probability (the probability of being correctly detected when the perceived object exists), false alarm probability (the probability of erroneously detecting the perceived target when the perceived object does not exist), perceived security, perceived privacy);

[0444] Perceived measurement quantity;

[0445] Perceived measurement result, such as including the perceived result directly or indirectly obtained based on at least one perceived measurement quantity;

[0446] Perceived conditions, such as including at least one of the perceived start time, perceived end time, perceived duration, etc.;

[0447] Perceived target or prior information of the perceived area, such as including at least one of the perceived target type, the location / area of the perceived target, the historical state of the perceived target (speed, angle, distance, acceleration, spatial orientation), etc.;

[0448] Perceived mode switching success determination condition (for example, indicating that the measurement results of at least one perceived measurement quantity and / or communication measurement quantity reach a preset threshold within a preset time / preset number of times);

[0449] Switching type, including hard handover and soft handover.

[0450] Step 4: Perform the handover

[0451] After receiving the handover request message, the second device decides whether to accept the handover / perform the perception. It is divided into the following two cases:

[0452] If it agrees, the second device sends a handover response message to the sender of the handover request information (Device A or the perception network function), and the handover response message indicates to the sender of the handover request information that the sender of the handover response message agrees to perform the perception measurement.

[0453] Optionally, the second device feeds back the proposed second signal configuration information in the handover response message. The second signal configuration information is used for the signal configuration of the second device to perform the perception measurement.

[0454] If not agreeing, the second device sends a rejection handover message to the first request message sender (Device A or the sensing network function), where the rejection handover message instructs the first request message sender that the rejection handover message sender does not perform sensing.

[0455] The subsequent processing can be one of the following: i. Device A or the sensing network function re-determines the second device; ii. Maintain the current sensing; iii. End the current sensing;

[0456] After receiving the handover response message, Device A or the sensing network function determines at least one target device in the second device as the device to perform sensing measurement after handover, and Device A or the sensing network function sends a handover command to the target device to notify the target device to perform sensing measurement;

[0457] Specifically, it includes the following situations:

[0458] After sending the handover command to the target device, Device A or the sensing network function notifies Device B to end the sensing measurement operation, Device A stops sending the first signal, and releases the occupied resources (including time-frequency resources, antenna port resources, etc.); Device A continues to send the second signal, and the target device performs sensing measurement based on the second signal. Among them, the first signal is the signal originally sent by Device A and received by Device B for sensing measurement, and the second signal is the signal sent by Device A and received by the target device for handover measurement, and the target device multiplexes this signal for subsequent sensing measurement;

[0459] After sending the handover command to the target device, Device A or the sensing network function notifies Device B to end the sensing measurement operation, Device A stops sending the first signal, and releases the occupied resources (including time-frequency resources, antenna port resources, etc.); Device A sends the fifth signal, and the target device performs sensing measurement based on the fifth signal. Among them, the first signal is the signal originally sent by Device A and received by Device B for sensing measurement, and the fifth signal is a new signal sent by Device A for sensing measurement, and the target device performs subsequent sensing measurement based on the fifth signal;

[0461] After device A or the sensing network function sends a handover command to the target device, the target device performs sensing measurements based on the second signal. After the target device completes at least one sensing measurement to obtain a sensing result (optionally, and the corresponding sensing-related metrics or communication-related metrics exceed a preset threshold), the target device sends feedback information to device A or the sensing network function. Device A or the sensing network function notifies device B to end the sensing measurement operation, and device A stops sending the first signal and releases the occupied resources. Among them, the first signal is the signal originally sent by device A and received by device B for sensing measurement, and the second signal is the signal sent by device A and received by the target device for handover measurement. The target device multiplexes this signal for subsequent sensing measurements;

[0462] After device A or the sensing network function sends a handover command to the target device, it sends a fifth signal to the target device. The target device performs sensing measurements based on the fifth signal. After the target device completes at least one sensing measurement to obtain a sensing result (optionally, and the corresponding sensing-related metrics or communication-related metrics exceed a preset threshold), the target device sends feedback information to device A or the sensing network function. Device A or the sensing network function notifies device B to end the sensing measurement operation, and device A stops sending the first signal and releases the occupied resources. Among them, the first signal is the signal originally sent by device A and received by device B for sensing measurement, and the fifth signal is a new signal sent by device A for sensing measurement. The target device performs subsequent sensing measurements based on the fifth signal;

[0463] After device A or the sensing network function sends a handover command to the target device, device A continues to send the first signal. The target device performs sensing measurements based on the first signal. After the target device completes at least one sensing measurement to obtain a sensing result (optionally, and the corresponding sensing-related metrics or communication-related metrics exceed a preset threshold), the target device sends feedback information to device A or the sensing network function. Device A or the sensing network function notifies device B to end the sensing measurement operation. Among them, the first signal is the signal originally sent by device A and received by device B for sensing measurement, and the signal sent by device A and received by the target device for handover measurement (that is, the first signal and the second signal are the same signal). The target device multiplexes this signal for subsequent sensing measurements.

[0464] Embodiment 2:

[0465] In this embodiment, the process of keeping the sensing signal receiving device unchanged and switching the sensing signal sending device is mainly described.

[0466] In this embodiment, device A sends a sensing signal, device B receives the sensing signal and measures it, then switches to device C to send the sensing signal, and device B receives the sensing signal and measures it.

[0467] Step 1: Trigger measurement

[0468] Device A transmits a first signal. Device B receives the first signal and performs sensing measurements. When a measurement switching trigger event is satisfied, Device B or the sensing network function sends switching measurement configuration information to a candidate target device (the second device).

[0476] The measurement report configuration includes the measurement report configuration for the second signal or the third signal, such as the principle for the second device to report to Device B or the sensing network function, which can be periodic reporting or event-triggered reporting; the type of reference signal for measurement, etc.; the measurement report format, such as the number of beams reported, etc.;

[0477] The above measurement content information may include at least one of the following:

For example, if the received power of the signal path associated with the sensing target based on the first signal is P1, then the threshold value is α*P1, where α is a scaling factor;

[0479] At least one perception measurement quantity associated with the second signal or the third signal (which can be a combination of one or several), such as the distance d1 from device B to the perception target or the distance d2 from the perception target to the second device measured based on the second signal; or the difference or ratio between d1 and d2; or the bistatic distance d_bi (d_bi = d1 + d2) measured based on the second signal; or the distance d3 from the perception target to the second device measured based on the third signal;

[0482] The value of at least one perception measurement quantity measured based on the second signal or the third signal meets a preset condition, such as d1 ≥ α * d2 measured based on the second signal, where α is a scaling factor; or d1 - d2 exceeds a preset threshold; or d3 measured based on the third signal is lower than a preset threshold;

[0483] The measurement assistance information can include at least one of the following:

[0484] The position information of the perception target, or the direction information relative to the second device (which helps the second device adjust the spatial domain filter / spatial domain filter coefficient (the received beam used) when receiving the second signal, or adjust the spatial domain filter / spatial domain filter coefficient when transmitting and receiving the third signal, or adjust the spatial domain filter / spatial domain filter coefficient when transmitting the fourth signal);

[0485] The position information of device B, or the direction information of device B relative to the second device, or the distance information between device B and the second device

[0486] The recommended transmission configuration or reception configuration, such as whether to use omnidirectional transmission or reception, or the transmission or reception beam index used, etc.

[0487] Among them, device B or the second device can judge whether the measurement event is satisfied according to the average value of multiple measurement quantities / indexes at different times (layer 1 filtering and / or layer 3 filtering), or judge that the values of the measurement quantities / indexes of continuous multiple measurements meet the preset conditions, so as to avoid the randomness / ping-pong effect caused by judging according to a single result;

[0488] The determination of the second device is based on the second device status information (which can be sent by the second device to Device B or the sensing network function, and Device B or the sensing network function determines the second device list according to the second device status information; or Device B obtains the second device list from the sensing network function), and the second device status information includes at least one of the following:

[0494] If the second device is a terminal, it further includes the status information of the UE.

[0495] Step 2: Perform measurements

[0496] After receiving the handover measurement configuration information, the second device performs handover measurements based on the second signal or the third signal and feeds back a handover measurement report to the sensing network function or Device B; the handover measurement report includes at least one of the values of the sensing measurement quantities, the values of the sensing-related or communication-related metrics, and the identifiers satisfying the corresponding measurement events.

[0497] Alternatively, Device B performs handover measurements based on the fourth signal sent by the second device to obtain a handover measurement report and sends it to the sensing network function.

[0498] Step 3: Handover decision

[0499] Device B decides whether to initiate a handover based on the handover measurement report reported by the second device, or based on the measurement of the fourth signal sent by the second device.

[0500] Optionally, Device B receives the handover measurement report from the second device and reports the handover measurement report to the sensing network function, and the sensing network function decides whether to initiate a handover request; or, the sensing network function decides whether to initiate a handover according to the handover measurement report received from the second device; or, Device B obtains a handover measurement report based on the measurement of the fourth signal sent by the candidate target and reports it to the sensing network function, and the sensing network function decides whether to initiate a handover request;

[0501] If the handover is not initiated, the subsequent processing can be to maintain or end the current sensing measurement, that is, still perform sensing measurements based on the first signal sent by Device A and received by Device B, or stop the sensing measurements.

[0502] If a handover is initiated, Device B or the sensing network function determines a second device and sends a handover request message to it. The definition of the handover request message is the same as that in Embodiment 1.

[0503] Step 4: Perform handover

[0504] After receiving the handover request message, the second device decides whether to accept the handover / perform sensing. There are the following two cases:

[0505] If it agrees, the second device sends a handover response message to the sender of the handover request message (Device B or the sensing network function).

[0506] If it does not agree, the second device sends a handover rejection message to the sender of the first request message (Device B or the sensing network function).

[0507] Subsequent processing can be one of the following: i. Device B or the sensing network function re-determines the second device; ii. Maintain the current sensing; iii. End the current sensing;

[0508] After receiving the handover response message, Device B or the sensing network function determines at least one target device in the second device as the device for performing sensing measurement after handover. Device B or the sensing network function sends a handover command to the target device to notify the target device to perform sensing measurement;

[0509] Specifically, it includes the following cases:

[0510] After Device B or the sensing network function sends a handover command to the target device, it notifies Device A to end the sensing measurement operation. Device A stops sending the first signal and releases the occupied resources (including time-frequency resources, antenna port resources, etc.); the target device sends a fourth signal, and Device B performs sensing measurement based on the fourth signal. Among them, the first signal is the signal originally sent by Device A and received by Device B for sensing measurement, and the fourth signal is the signal sent by the target device and received by Device B for handover measurement. The target device multiplexes this signal for subsequent sensing measurement;

[0511] After Device B or the sensing network function sends a handover command to the target device, it notifies Device A to end the sensing measurement operation.

Among them, the first signal is the signal originally sent by Device A and received by Device B for sensing measurement, and the fifth signal is a new signal sent by the target device for sensing measurement. The target device performs subsequent sensing measurement based on the fifth signal;

[0512] After the device B or the sensing network function sends a handover command to the target device, the device B performs sensing measurements based on the fourth signal. After the device B completes at least one sensing measurement to obtain a sensing result (optionally, and the corresponding sensing-related metrics or communication-related metrics exceed a preset threshold), the device B or the sensing network function notifies the device A to end the sensing measurement operation, and the device A stops sending the first signal and releases the occupied resources. Among them, the first signal is the signal originally sent by the device A and received by the device B for sensing measurement, and the fourth signal is the signal sent by the target device and received by the device B for performing handover measurements. The target device multiplexes this signal for subsequent sensing measurements;

[0513] After the device B or the sensing network function sends a handover command to the target device, the target device sends a fifth signal, and the device B performs sensing measurements based on the fifth signal. After the device B completes at least one sensing measurement to obtain a sensing result (optionally, and the corresponding sensing-related metrics or communication-related metrics exceed a preset threshold), the device B or the sensing network function notifies the device A to end the sensing measurement operation, and the device A stops sending the first signal and releases the occupied resources. Among them, the first signal is the signal originally sent by the device A and received by the device B for sensing measurement, and the fifth signal is a new signal sent by the target device for sensing measurement. The target device and the device B perform subsequent sensing measurements based on the fifth signal.
