[0083] Please refer to Figure 3 , Figure 3 which is a flowchart of a perception measurement method provided by an embodiment of the present application. As Figure 3 shown, it includes the following steps:

[0084] Step 301, the first device obtains first information;

[0085] Among them, the first information includes at least one of the following:

[0086] Perception-related indicators obtained by measuring the first signal;

[0087] Perception measurement results obtained by measuring the first signal;

[0088] Device information of the first device.

[0089] The above-mentioned first device may be a terminal or a network-side device.

[0090] The above-mentioned acquisition of the first information may be that the first device acquires the above-mentioned first information by means of measurement. Or the first device acquires the above-mentioned first information through a sensor.

[0091] The above-mentioned measurement of the first signal may be that the first device receives the first signal sent by the second device and performs measurement, that is, the above-mentioned first device is the receiving device of the above-mentioned first signal.

[0092] The above-mentioned measurement of the first signal may be that the first device sends the first signal and performs measurement, that is, the above-mentioned first device is the sending device of the above-mentioned first signal, such as self-transmission and self-reception measurement of the device.

[0093] In the embodiments of the present application, the above-mentioned first signal may be a dedicated signal for sensing services, or a communication signal, such as a reference signal or a synchronization signal, etc.

[0094] Among them, the dedicated signal for sensing services may 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.;

[0095] Among them, the reference signal may 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.;

[0096] The above-mentioned synchronization signal may be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS), etc.

[0097] The above-mentioned 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.

[0098] Among them, the above-mentioned perception-related metrics may be perception-related metrics obtained by the first device during the measurement process of the first signal, or may be perception-related metrics obtained by the first device during the reception process of the first signal.

[0099] The above-mentioned perception-related metrics refer to perception-associated metrics, such as metrics affected by the perception target or metrics affecting the perception measurement, etc. Specifically, they may be the measurement values or values of the perception-related metrics.

[0100] The above-mentioned perception measurement result may be the measurement result of at least one perception measurement quantity.

[0101] The device information of the above-mentioned first device may include at least one of the following

[0102] The movement direction of the device, the magnitude of the movement speed of the device, the location information of the device, the orientation information of the device.

[0103] Among them, the orientation information of the device may refer to the orientation information of a specific device of the device, such as the orientation information of devices such as antennas, sensors, and screens.

[0104] The above-mentioned device information may be obtained by the first device according to its own sensor device, or may be measured by the first device according to the received first signal.

[0105] The above-mentioned preset conditions may be defined by the protocol, or may be conditions obtained by the first device by receiving information sent by the second device, such as conditions obtained through broadcast signaling, System Information Block (SIB), RRC signaling, MAC CE, layer 1 signaling, or data channels, etc.

[0106] In the embodiments of the present application, the above-mentioned second device may be a terminal or a network-side device, or a perception network function, and when the first device is a terminal, the second device may be a terminal or a network-side device, or a perception network function, and when the first device is a network-side device, the second device may be a terminal or a network-side device, or a perception network function.

[0107] Step 302: When the first information meets the preset conditions, the first device performs a sensing measurement action.

[0108] When the first information meets the preset conditions, the first device performing a sensing measurement action can be understood as that when the first information meets the preset conditions, the first device performs a sensing measurement action, and when the first information does not meet the preset conditions, it does not perform or stops performing the sensing measurement action.

[0109] In the embodiments of the present application, through the above steps, it can be realized that when the first information meets the preset conditions, the first device performs a sensing measurement action, so as to reduce the number of times of performing the sensing measurement action, and thus the overhead of sensing measurement can be saved.

[0110] In addition, since the above first information includes sensing-related metrics, this can make the first device perform the sensing measurement action more reliably, because the validity of the sensing measurement result is closely related to the sensing-related metrics, and it is easier to avoid the first device from performing unnecessary sensing measurement actions.

[0111] Since the above first information includes the sensing measurement result, this can make the first device perform the sensing measurement action more reliably, because it is easier to avoid the first device from performing unnecessary sensing measurement actions through the sensing measurement result.

[0112] And the above first information includes the device information of the first device, and the device information can also well avoid the first device from performing unnecessary sensing measurement actions, thereby making the first device perform the sensing measurement action more reliably.

[0113] As an optional implementation manner, the sensing measurement action includes at least one of the following:

[0114] Measuring a first signal to obtain a sensing measurement result;

[0115] Sending the sensing measurement result;

[0116] Sending the sensing-related metrics;

[0117] Sending the device information, where the device information is used for sensing;

[0118] Sending indication information, where the indication information indicates that the first device can participate in sensing;

[0119] Sending a second signal, where the second signal is used for sensing.

[0120] Wherein, when the above first information does not include the perception-related metrics obtained by measuring the first signal, that is, when judging the above preset conditions, the perception-related metrics obtained by measuring the first signal are not considered (for example, for the above preset conditions, only device information or perception measurement results are considered), the perception measurement behavior may or may not include the above sending of perception-related metrics, which can be specifically determined according to actual needs;

[0121] When the above first information includes the perception measurement results obtained by measuring the first signal, the perception measurement behavior does not include the perception measurement results obtained by measuring the first signal; the perception measurement behavior including obtaining the perception measurement results by measuring the first signal can be achieved when the first information includes the above device information or perception-related metrics.

[0122] When the above first information does not include the perception measurement results obtained by measuring the first signal, that is, when judging the above preset conditions, the perception measurement results obtained by measuring the first signal are not considered (for example, for the above preset conditions, only device information or perception-related metrics are considered), the perception measurement behavior may or may not include the above sending of perception measurement results, which can be specifically determined according to actual needs.

[0123] When the first information does not include the device information of the first device, that is, when judging the above preset conditions, the device information is not considered, the above perception measurement behavior may or may not include sending the device information of the first device, which can be specifically determined according to actual needs.

[0124] The above device information being used for perception means that the device receiving the above device information uses the above device for perception-related calculations during the perception process.

[0125] The above second signal can be a dedicated signal for the perception service, or a communication signal, such as a reference signal or a synchronization signal, etc. For specific details, refer to the corresponding description of the above first signal, which will not be elaborated here.

[0126] The above sending of the second signal means that the first device sends the second signal to other devices, and these devices perform perception-related measurements on the second signal, or the first device sends the above second signal and the first device performs the measurement, that is, the first device performs self-transmission and self-reception measurement.

[0127] In the above optional implementation manner, since when the first information meets the preset conditions, the above at least one perception measurement behavior is executed, the overhead of perception measurement can be saved.

[0128] As an optional implementation manner, the perception-related metrics include at least one of the following:

[0129] Perception metrics related to received power;

[0130] Perception metrics related to interference or noise power;

[0131] Perception metrics related to received power and also related to interference or noise power.

[0132] Among them, the above perception metrics related to received power may include at least one of the following:

[0133] Perception metrics related to the received power of the target signal, perception metrics related to the received power of the signal path of the target signal associated with the perception target. For example: the above perception metrics related to received power include: the first metric, the first metric is used to indicate the received power of the signal path associated with the perception target in the signal paths of the first signal, that is, the first metric is used to indicate the received power of at least one signal path of the first signal associated with the perception target.

[0134] Among them, the signal path associated with the above perception target may be a signal path affected by the perception target or a signal path passing through the perception target.

[0135] In the above optional implementation manner, since the perception-related metrics include perception metrics related to received power, it is possible to determine whether to perform a perception measurement behavior based on the received power, so that the execution of the perception measurement behavior is more reliable. In addition, it is also possible to determine whether to perform a perception measurement behavior 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 perception measurement behavior needs to be performed. Therefore, the above first metric can make the perception measurement behavior more reliable.

[0136] In some embodiments, the above first metric may be the linear average (in units of W) of the received power of the signal path associated with the perception target in the channel response measured for the first signal on the resource unit carrying the first signal, and 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. It should be noted that the embodiments of the present application do not limit the received power to be the linear average. For example: in some embodiments, it may also be the median received power, the lowest received power, or the highest received power.

[0137] The above 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.

[0138] In the above-mentioned optional implementation manner, since the perception-related metrics include perception metrics related to interference or noise power, it is possible to take interference or noise into account when determining whether to perform a perception measurement behavior, making the perception measurement behavior more reliable.

[0139] Optionally, the perception metrics related to interference or noise power include at least one of the following:

[0140] 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, or the total received power is the power corresponding to the received signal strength indication (RSSI) of the first device on the first resource;

[0141] 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, or the total received power is the power corresponding to the RSSI of the first device on the first resource;

[0142] 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;

[0143] Wherein, the first metric is used to indicate the received power of the signal path associated with the perception target in the signal paths of the first signal, 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.

[0144] 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.

[0145] 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.

[0146] The above-mentioned first resource includes the target resource or at least one resource other than the target resource means that the first resource includes at least one of the following:

[0147] The target resource, and at least one resource other than the target resource.

[0148] 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:

[0149] The target resource, and at least one resource other than the target resource.

[0150] Among them, the above-mentioned at least one resource other than the target resource may 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 the resources configured by high-layer signaling or the resources that the first device has predetermined to detect or receive signals.

[0151] The above-mentioned interference or noise power includes the sum of interference power and noise power, interference power, or noise power.

[0152] 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, thermal noise power, etc. And the above-mentioned 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.

[0153] The power corresponding to the 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 RSSI may also be RSSI, that is, the total received power = RSSI.

[0154] The received power of the first signal refers to the RSRP of the first signal.

[0155] The above-mentioned 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.

[0156] The above-mentioned 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.

[0157] The above-mentioned 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.

[0158] In the above-mentioned embodiments, by using the second metric, it is possible to consider the interference or noise of other signal paths and other signals other than the signal paths associated with the sensing target when determining whether to perform the sensing measurement behavior, so that the sensing measurement behavior can be made more reliable.

[0159] In the above embodiments, by means of the above third metric, interference or noise of other signals besides the first signal can be considered when determining whether to perform the sensing measurement behavior, so that the sensing measurement behavior can be made more reliable.

[0160] In the above embodiments, by means of the above fourth metric, the power of other signal paths besides the signal path associated with the sensing target can be considered when determining whether to perform the sensing measurement behavior, so that the sensing measurement behavior can be made more reliable.

[0161] 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.

[0162] In one of the above optional embodiments, since the metrics related to sensing include the sensing metrics related to the received power and also related to the interference or noise power, it is possible to take into account the received power and the interference or noise when determining whether to perform the sensing measurement behavior, so that the sensing measurement behavior can be made more reliable.

[0163] In some embodiments, the sensing metrics related to the received power and also related to the interference or noise power include at least one of the following:

[0164] A fifth metric, where the fifth metric is equal to the quotient obtained by dividing the first metric by the second metric;

[0165] A sixth metric, where the sixth metric is equal to the quotient obtained by dividing the first metric by the third metric;

[0166] A seventh metric, where the seventh metric is equal to the quotient obtained by dividing the first metric by the fourth metric;

[0167] An eighth metric, where the eighth metric is equal to the product of the quotient obtained by dividing the first metric by the total received power and the target coefficient.

[0168] Among them, for the above first metric, second metric, third metric, and fourth metric, refer to the above embodiments and will not be elaborated here. It should be noted that in the case of including at least one of the above fifth metric, sixth metric, seventh metric, and eighth metric, the sensing-related metrics in the embodiments of the present application may or may not include the above first metric, second metric, third metric, and fourth metric.

[0169] The above target coefficient can be expressed as K2. For example, the eighth metric = K2 * first metric / total received power, where K2 is a coefficient, and K2 can specifically be agreed upon by the protocol or configured by the network side.

[0170] In this embodiment, by using the above fifth index, sixth index, seventh index or eighth index, it is possible to consider the received power and interference or noise when determining whether to perform the sensing measurement behavior, so that the sensing measurement behavior is more reliable.

[0171] In some embodiments, the sensing metrics related to the received power and also related to the interference or noise power may further include at least one of the following:

[0172] Metrics related to sensed SINR, metrics related to sensed SNR, metrics related to sensed Signal Interference Ratio (SIR), metrics related to sensed RSRQ.

[0173] As an alternative embodiment, the signal paths associated with the sensing target satisfy at least one of the following:

[0174] The parameter satisfies a first preset threshold, or the parameter is within a first preset interval range;

[0175] The parameter satisfies a preset modulation rule;

[0176] The difference in parameters from the first-arrival signal path satisfies a second preset threshold, or the difference in parameters from the first-arrival signal path is within a second preset interval range;

[0177] The difference in parameters from the reference signal path satisfies a third preset threshold, or the difference in parameters from the reference signal path is within a third preset interval range.

[0178] Wherein, the above parameters may include at least one of the following:

[0179] Amplitude, power, intensity, energy, phase, Doppler, delay, angle.

[0180] The above parameter differences may include at least one of the following:

[0181] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, delay difference, angle difference.

[0182] 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 may be agreed upon by the protocol or configured by the network side, or these preset thresholds or preset interval ranges are determined by the receiving device according to the sensing prior information or sensing requirements. The above parameter satisfying the first preset threshold may mean that the parameter exceeds or is equal to the first preset threshold, the difference in parameters from the first-arrival signal path satisfying the second preset threshold may mean that the difference in parameters from the first-arrival signal path exceeds or is equal to the second preset threshold, and the difference in parameters from the reference signal path satisfying the third preset threshold may mean that the difference in parameters from the reference signal path exceeds or is equal to the third preset threshold.

[0183] For example, if the sensing service is moving target detection, it is necessary to detect the signal path with Doppler greater than zero as the signal path associated with the sensing target; or for traffic scene sensing, if the 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 if 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 respiratory monitoring, then the normal respiratory 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 prior sensing information, and the corresponding Doppler range, 0.25 to 0.5 Hz, can be calculated).

[0184] The above first-arrival signal path can be a line-of-sight (LOS) path, specifically the signal path that first arrives at the receiving end 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 intelligence surface (RIS), backscatter, or other known passive targets, etc.

[0185] The above preset modulation rules can be agreed upon by the protocol or configured by the network side. The specific modulation rules are the modulation rules of tags, backscatter devices, or RISs, that is, the paths associated with the sensing target can be the signal paths modulated and reflected by tags, backscatter devices, or RISs.

[0186] In one of the above optional embodiments, 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.

[0187] In some embodiments, before determining the signal paths associated with the sensing target, a set of signal paths can also be determined, and the set of signal paths includes signal paths with amplitude, power, intensity, or energy exceeding a certain threshold, such 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 complexity.

[0188] Next, an example is given to illustrate the index calculation of the embodiments of the present application. It should be noted that the calculation of each index in the embodiments of the present application is not limited, and the following embodiments are only for illustrative purposes.

[0189] Calculation method 1 of the first indicator:

[0190] The first device (such as a terminal) performs channel estimation based on the transmitted target signal X(k) and the received signal Y(k) corresponding to the target 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 target dimension and determines the signal paths associated with the sensing target in the target dimension. Then, it calculates the power of the signal paths associated with the sensing target as the first indicator. If the signal paths associated with the sensing target include multiple signal paths, it calculates the sum of the powers of the multiple signal paths as the first indicator.

[0191] Among them, the target dimension includes one of the following:

[0192] Delay dimension;

[0193] Doppler dimension;

[0194] Azimuth angle dimension;

[0195] Elevation angle dimension;

[0196] A dimension that combines at least two of the delay dimension, Doppler dimension, azimuth angle dimension, and elevation angle dimension. For example, the delay-Doppler dimension, the delay-Doppler-angle dimension, etc.;

[0197] For example, if H(f) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency domain sampling points (such as subcarrier indices), then it can be transformed to the delay dimension (target dimension) by performing an inverse Fourier transform on H(f); again, for example, if H(f,t) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency domain sampling points (such as subcarrier indices) and t = 0, 1, 2, …, M - 1 represents the time domain sampling points (such as OFDM symbol indices), then it can be transformed to the delay-Doppler dimension (target dimension) by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension on H(f,t); again, for example, if H(f,t,s) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency domain sampling points (such as subcarrier indices), t = 0, 1, 2, …, M - 1 represents the time domain sampling points (such as OFDM symbol indices), and s = 0, 1, 2, …, P - 1 represents the spatial domain sampling points (antenna indices or port indices), then it can be transformed to the delay-Doppler-angle dimension (target dimension) 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).

[0198] The determination method of the signal paths associated with the sensing target (simply referred to as sensing paths) in the channel response measured for the target signal may include the following:

[0199] 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 paths after the channel response is transformed into the target 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 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.

[0200] Select the signal paths that meet the target conditions from the set of signal paths or from all the signal paths of the target signal as the signal paths associated with the sensing target. The target conditions include at least one of the following:

[0201] The amplitude, power, intensity, or energy of the signal path exceeds a preset threshold or is within a preset range, such as the preset threshold is 5 times higher than the noise threshold;

[0202] The Doppler of the signal path exceeds a preset threshold or is within a preset range;

[0203] The delay of the signal path exceeds a preset threshold or is within a preset range;

[0204] The angle of the signal path exceeds a preset threshold or is within a preset range;

[0205] The difference between the amplitude / power / intensity / energy of the signal path and the first-arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset range, where the reference signal path can be the signal path reflected by a known target (such as RIS / Backscatter / other known passive targets, etc.);

[0206] The Doppler difference between the signal path and the first-arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0207] The delay difference between the signal path and the first-arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0208] The angle difference between the path and the first-arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0209] 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 sensing target can be the signal path modulated and reflected by the Tag / Backscatter device or RIS

[0210] Among them, the above-mentioned target conditions of each item can also be based on the results of statistics over a period of time; for example, within a preset time window, the proportion of the above-mentioned indicators (such as Doppler of the path, time delay of the path, etc.) exceeding a preset threshold or falling within a preset interval range reaches a preset proportion, or the number of times the above-mentioned indicators (such as Doppler of the path, time delay of the path, etc.) exceed a preset threshold or fall within a preset interval range within a preset time window reaches a preset number of times;

[0211] Among them, the preset threshold or the set interval range is sent by other devices to the receiving device and determined by other devices according to the perceived prior information or the perceived requirements. Or, the preset threshold or the preset interval range can be an agreement in the protocol, or the preset threshold or the preset interval range is determined by the receiving device according to the perceived prior information or the perceived requirements.

[0212] Among them, the perceived prior information or the perceived requirements include the following information:

[0213] Perceived services or types of perceived services. The perceived services can be, for example, detecting whether a target exists, 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 flow or vehicle flow detection, crowd density, vehicle density detection, etc.; The types of perceived services can classify multiple different perceived services according to certain characteristics. For example, they can be classified into detection-type perceived services (such as including intrusion detection, fall detection), parameter estimation-type perceived services (distance, angle, speed calculation), recognition-type perceived services (action recognition, identity recognition), etc. according to functions, and can also be classified according to the perceived range (close-range perception, medium-range perception, long-range perception), according to the perceived fineness (coarse-grained perception, fine-grained perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc. If the perceived service is respiration monitoring, the corresponding normal respiration 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 the perceived prior information;

[0214] Perceived target area: It refers to the position area of the perceived object, or the position area where imaging or environmental reconstruction needs to be performed; for example, determining the preset interval range of the time delay of the signal path associated with the perceived target according to the approximate position / distance of the perceived object.

[0215] Perceived object type: Classify the perceived object according to its possible motion characteristics. Each perceived object type contains information such as the motion speed range, motion acceleration range, and typical RCS range of typical perceived objects.

[0216] Number of perceived targets; for example, as a kind of prior information of perception, the perception result of the camera can obtain the number of perceived targets.

[0217] 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 perceived paths that meet the target conditions (for example, their time delays meet the preset threshold), and paths 0, 1 are the paths associated with other scatterers.

[0218] Among them Figure 4 In, it is a schematic diagram of multiple signal paths in the target dimension (time delay dimension, Doppler dimension, azimuth dimension, or elevation dimension) of the channel response. Among them, the horizontal axis is the target dimension, and the vertical axis is the normalized amplitude, power, intensity, or energy.

[0219] For frequency range 1, the reference point of the first index can be the antenna connector of the receiving device such as the terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first index measured and reported by the receiving device cannot be lower than the index of any single receiving channel. For frequency range 2, the first index measured by a certain receiving channel needs to be obtained by measuring the combined signals on multiple antenna elements corresponding to this receiving channel.

[0220] Calculation method 2 of the first index:

[0221] When calculating the received power of the signal path associated with the perceived target, it can also be the difference between the power of the signal path associated with the perceived target in the target dimension and as the first index, where N1 represents the number of signal paths associated with the perceived target. is the average power of multiple signal paths outside the signal path set in the target dimension.

[0222] Calculation method 1 of the received power of the target signal:

[0223] The received power of the target signal can be obtained by the receiving device after obtaining the channel response H(k), transforming it to the target dimension, determining the signal path set in the target dimension, and then calculating the sum of the powers of all signal paths in the signal path set.

[0224] Calculation method 2 of the received power of the target signal:

[0225] The received power of the target signal can also be the difference between the sum of the powers of all signal paths in the signal path set in the target dimension and where N2 represents the number of signal paths in the signal path set.

[0226] Calculation method of the total received power:

[0227] Total received power

[0228] where Y(k) is the received signal corresponding to the target signal, k = 0, 1, 2, …, K - 1 represents the resource unit index, and K is the number of resource units.

[0229] Calculation method of the second indicator:

[0230] The channel response H(k) is subjected to the first filtering process to obtain H filter1 (k), and then the received signal Y filter1 after the first filtering process is calculated according to H filter1 (k) and the target signal X(k), that is, Y filter1 (k) = H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter1 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:

[0231]

[0232] where the first filtering process is used to eliminate noise, interference, and paths not associated with the perceived target in the target dimension. For example, the first filtering process sets Figure 4 the amplitude, power, intensity, or energy of other paths except for the paths associated with the perceived target to zero. The channel response H filter1 after the first filtering process does not contain noise, interference, and paths not associated with the perceived target, and only contains paths associated with the perceived target.

[0233] Calculation method 1 of the third indicator:

[0234] 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 target 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 metric is calculated:

[0235]

[0236] The above second filtering process can be a noise interference suppression process in the target dimension (for example Figure 4 setting 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) after the second filtering process does not contain noise and interference, but only contains the paths in the signal path set.

[0237] Calculation method 2 of the third metric:

[0238] Based on the average power of multiple signal paths outside the signal path set in the target dimension the third metric P σ2 is calculated, that is where N represents the number of sampling points in the target dimension.

[0239] It should be noted that if the receiving device determines multiple sensing targets, or the receiving device obtains the number of sensing targets based on sensing prior information or sensing requirements, then there are the following methods:

[0240] Method 1: Calculate the sensing-related metrics (which can also be called target metrics) for each sensing target respectively. For example, in Figure 4Respectively determine the signal paths associated with each sensing target, and then calculate the various sensing-related metrics corresponding to each sensing target; when calculating the second metric corresponding to a certain sensing target (such as sensing target A), there are two methods: namely: the second metric of sensing target A = total received power - the first metric of sensing target A; or, the second metric of sensing target A = total received power - the first metric of sensing target A - the first metric 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 metric: the fourth metric of sensing target A = RSRP of the target signal - the first metric of sensing target A; or, the fourth metric of sensing target A = RSRP of the target signal - the first metric of sensing target A - the first metric of sensing target B; (assuming there are two sensing targets in total: A and B)

[0241] Method 2: Calculate a sensing-related metric 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 calculating the sensing-related metric corresponding to this virtual sensing target.

[0242] As an optional implementation manner, the first information satisfying the preset condition includes at least one of the following:

[0243] The sensing-related metric satisfies the preset metric threshold requirement;

[0244] The sensing measurement result satisfies the preset sensing requirement;

[0245] At least one of the motion direction, motion speed magnitude, position information, or orientation information included in the device information of the first device satisfies the preset device threshold requirement.

[0246] Among them, the above-mentioned preset metric threshold requirement, preset sensing requirement, and preset device threshold requirement can be agreed upon by the protocol or configured by the network side, or determined by the first device.

[0247] The above-mentioned sensing-related metric satisfying the preset metric threshold requirement can be that the sensing-related metric reaches the preset metric threshold, or it can be that the sensing-related metric is within the preset metric threshold range.

[0248] The above-mentioned sensing measurement result satisfying the preset sensing requirement can be that the sensing measurement result indicates whether a sensing target or a signal path associated with the sensing target is detected, or the sensing measurement result (such as time delay, Doppler, angle, etc.) is within the preset sensing threshold range, or the target position coordinates calculated based on the sensing measurement result are within the preset position range.

[0249] At least one of the motion direction, motion speed magnitude, position information, or orientation information included in the device information of the first device satisfying the preset device threshold requirements may include at least one of the following:

[0250] The motion direction included in the device information of the first device matches the preset direction, or the motion direction is within the preset azimuth range;

[0251] The magnitude of the motion speed of the first device exceeds the preset speed threshold, or the magnitude of the motion speed is within the preset speed threshold range;

[0252] The position information of the first device is within the preset position range;

[0253] The orientation information of the first device matches the preset direction, or the angle between the orientation of the device and the direction of the area where the perceived target is located is less than the preset threshold.

[0254] In one of the above optional embodiments, it is possible to determine whether to perform the perception measurement behavior based on multiple dimensions to meet more perception service requirements and improve the compatibility of the perception measurement.

[0255] In some embodiments, the first information further includes communication-related metrics, where the communication-related metrics may include at least one of the following:

[0256] Reference Signal Received Power (RSRP), Received Signal Strength Indication (RSSI), Reference Signal Received Quality (RSRQ), Channel Quality Indicator (CQI), Signal to Interference plus Noise Ratio (SINR), Signal to Noise Ratio (SNR).

[0257] The first information satisfying the preset conditions further includes the communication-related metrics satisfying the preset communication requirements, such as the communication-related metrics reaching the preset threshold, or the communication-related metrics being within the preset threshold range.

[0258] This can achieve that when performing the perception measurement behavior, the communication-related metrics also need to satisfy the preset communication requirements, such as performing the perception measurement behavior when the communication-related metrics indicate better communication conditions, further improving the reliability of the perception measurement behavior.

[0259] As an alternative implementation, the above method further includes:

[0260] The first device receives second information, and the second information includes at least one of the following:

[0261] Relevant information of the preset condition, configuration information of the first signal, configuration information of the second signal, measurement configuration information, sensing requirement information, sensing prior information;

[0262] The second signal is a signal for sensing sent by the first device.

[0263] The above second information may be the second information sent by the second device received by the first device.

[0264] Among them, the relevant information of the preset condition may be the relevant information for determining the preset condition. For example, the relevant information of the preset condition may include at least one of the following:

[0265] Indicator information of the sensing-related metrics, threshold information related to the sensing-related metrics, requirement information for sensing measurement results, requirement information for the device information.

[0266] The above indicator information of the sensing-related metrics is used to indicate the sensing-related metrics in the above first information, that is, to indicate the sensing-related metrics for determining whether to perform a sensing measurement behavior. For example, it indicates at least one of the first metric to the eighth metric in the above implementation as the sensing-related metric for determining whether to perform a sensing measurement behavior.

[0267] Since the above second information includes the relevant information of the preset condition, the first device determines the preset condition based on this relevant information, so that the first device and the device sending the above second information have a consistent understanding of the sensing measurement behavior, thereby improving the sensing measurement performance between devices.

[0268] The configuration information of the first signal or the configuration information of the second signal may include at least one of the following:

[0269] Signal configuration identification ID, used to distinguish different signal configurations;
