[0004] Sensing has been introduced in some communication systems. During the sensing process, signal measurement, calculation of sensing measurement results, and feedback of these results all incur corresponding overhead.

In some related technologies, devices often directly perform sensing measurements—that is, they directly measure signals, calculate sensing measurement results, and directly feed back sensing measurement results. This direct sensing measurement behavior can result in useless measurements or feedback, leading to excessive sensing measurement overhead. Summary of the Invention

[0061] In addition, the embodiments of the present application can be applied to the communication and perception integration scenario, where communication and perception integration refers to the integrated design of communication and perception functions through spectrum sharing and hardware sharing in the same system.

It should be noted that each perception link in Figure 2 is illustrated by taking a sending node and a receiving node as an example. In the actual system, different perception links can be selected according to different perception needs. Each perception link may have one or more sending nodes and one receiving node, and the actual perception system may include a variety of different perception links. In addition, the perception targets in Figure 2 take people and cars as examples, and assuming that people and cars do not carry or install signal receiving / transmitting equipment, the perception targets of the actual scene will be richer.

[0070] In some embodiments, the signaling transmission between the wireless access network device and the terminal, or between different terminals, may be through Radio Resource Control (RRC) signaling or Medium Access Control Control Element (MAC CE) or Layer 1 signaling or other newly defined perception signaling; the signaling transmission between the perception network function and the terminal may be through Non-Access-Stratum (NAS) signaling (forwarded via AMF) or through RRC signaling or MAC CE or Layer 1 signaling or other newly defined perception signaling; the interaction between the perception network function and the base station may be forwarded to the wireless access network through the N2 interface by the AMF; or the core network perception network function may send it to the UPF, and the UPF may send it to the wireless access network through the N3 interface; or it may be sent to the wireless access network (such as a base station) through a newly defined interface; the signaling transmission between wireless access network devices may be through the Xn interface.

[0071] In some embodiments, the perception network function may also be called a perception network element or a perception management function (Sensing Management Function, Sensing MF), which may be located on the RAN side or the core network side. It refers to a network node in the core network or RAN responsible for at least one function such as perception request processing, perception resource scheduling, perception information interaction, and perception data processing. It may be based on an upgrade of the AMF or LMF in the mobile communication network, or it may be another network node or a newly defined network node. Specifically, the functional characteristics of the perception network function / perception network element may include at least one of the following:

[0073] The perception method to be used is determined based on factors such as the type of perception service, perception service consumer information, required perception service quality (QoS) requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device.

[0083] The following describes in detail a perception measurement method, apparatus, and device provided by the embodiments of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0084] Please refer to FIG3 , which is a flowchart of a perception measurement method provided in an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0085] Step 301: The first device obtains first information;

[0086] The first information includes at least one of the following:

[0087] a perception-related indicator obtained by measuring the first signal;

[0088] a perceptual measurement result obtained by measuring the first signal;

[0089] Device information of the first device.

[0090] The first device mentioned above may be a terminal or a network side device.

[0091] The first information may be obtained by the first device through measurement, or the first device may obtain the first information through a sensor.

[0092] The measuring of the first signal may be that the first device receives the first signal sent by the second device and performs the measurement, that is, the first device is a receiving device of the first signal.

[0093] The measurement of the first signal may be performed by the first device sending the first signal and performing the measurement, that is, the first device is a sending device of the first signal, such as the device transmitting and receiving the measurement autonomously.

[0094] In an embodiment 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.

[0095] The dedicated signal for the sensing service may be a sensing signal generated based on a chirp or frequency modulated continuous wave (FMCW) signal, or a sensing signal generated based on a pseudo-random (PN) sequence or a ZC (Zadoff Chu) sequence.

[0096] 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).

[0097] The synchronization signal may be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS).

[0098] The above-mentioned signal carrying communication data can be a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical downlink control channel (PDCCH) or a physical uplink control channel (PUCCH), etc.

[0099] The above-mentioned perception-related indicator may be a perception-related indicator obtained by the first device during a measurement process of the above-mentioned first signal, or may be a perception-related indicator obtained by the first device during a process of receiving the above-mentioned first signal.

[0100] The above-mentioned perception-related indicators refer to perception-related indicators, such as indicators affected by perception targets or indicators affecting perception measurements, etc., and specifically can be measurement values ​​or values ​​of perception-related indicators.

[0101] The above-mentioned perception measurement result may be a measurement result of at least one perception measurement quantity.

[0102] The device information of the first device may include at least one of the following:

[0103] The device's movement direction, the device's movement speed, the device's location information, and the device's orientation information.

[0104] The orientation information of the device may refer to the orientation information of a specific component of the device, such as an antenna, a sensor, a screen, or the like.

[0105] The above device information may be acquired by the first device based on its own sensor device, or may be obtained by the first device through measurement based on the received first signal.

[0106] The above-mentioned preset conditions may be defined by a 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, MACCE, layer 1 signaling or data channel.

[0107] In an embodiment of the present application, the above-mentioned second device can be a terminal or a network side device, or a perception network function, and when the first device is a terminal, the second device can 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 can be a terminal or a network side device, or a perception network function.

[0108] Step 302: When the first information meets a preset condition, the first device performs a sensing measurement behavior.

[0109] When the first information meets the preset condition, the first device performs the perception measurement behavior, which can be understood as, when the first information meets the preset condition, the first device performs the perception measurement behavior, and when the first information does not meet the preset condition, does not perform the perception measurement behavior or stops performing the perception measurement behavior.

[0110] In the embodiment of the present application, the above steps can be used to implement the first device performing a perception measurement behavior when the first information meets a preset condition, thereby reducing the number of times the perception measurement behavior is performed, thereby saving the overhead of the perception measurement.

[0111] In addition, since the first information includes the perception-related indicators, the first device can perform the perception measurement behavior more reliably, because the validity of the perception measurement result is closely related to the perception-related indicators, which makes it easier to avoid the first device from performing unnecessary perception measurement behavior.

[0112] Since the first information includes the perception measurement result, the first device can perform the perception measurement behavior more reliably, because the perception measurement result can more easily avoid the first device from performing unnecessary perception measurement behavior.

[0113] The above-mentioned first information includes the device information of the first device, and the device information can also effectively prevent the first device from performing unnecessary perception and measurement behaviors, thereby making the first device perform the perception and measurement behaviors more reliable.

[0114] As an optional implementation manner, the perception measurement behavior includes at least one of the following:

[0115] Measuring the first signal to obtain a perception measurement result;

[0116] sending the perception measurement result;

[0117] sending the perception-related indicators;

[0118] Sending the device information, where the device information is used for sensing;

[0119] Sending indication information, where the indication information indicates that the first device can participate in sensing;

[0120] A second signal is sent, where the second signal is used for sensing.

[0121] In this case, when the first information does not include the perception-related indicator obtained by measuring the first signal, that is, when the judgment of the preset condition does not consider the perception-related indicator obtained by measuring the first signal (for example, when the preset condition only considers the device information or the perception measurement result), the perception measurement behavior may include or exclude the sending of the perception-related indicator, which can be determined according to actual needs;

[0122] In the case where the above-mentioned first information includes the perception measurement result obtained by measuring the first signal, the perception measurement behavior does not include the perception measurement result obtained by measuring the first signal; the perception measurement behavior includes measuring the first signal to obtain the perception measurement result, which can be implemented when the first information includes the above-mentioned device information or perception-related indicators.

[0123] When the above-mentioned first information does not include the perception measurement result obtained by measuring the first signal, that is, when the judgment of the above-mentioned preset condition does not consider the perception measurement result obtained by measuring the first signal (such as when the above-mentioned preset condition only considers the device information or perception-related indicators), the perception measurement behavior may include or exclude the above-mentioned sending of the perception measurement result, which can be determined according to actual needs.

[0124] When the first information does not include the device information of the first device, that is, when the judgment of the above preset condition does not consider the device information, the above perception measurement behavior may include or exclude sending the device information of the first device, which can be determined according to actual needs.

[0125] The above-mentioned device information is used for perception, which means that the device that receives the above-mentioned device information uses the above-mentioned device to perform perception-related calculations during the perception process.

[0126] The above-mentioned second signal can be a dedicated signal for sensing services, or a communication signal, such as a reference signal or a synchronization signal, etc. For details, please refer to the corresponding description of the above-mentioned first signal, which will not be repeated here.

[0127] The above-mentioned sending of the second signal refers to the first device sending the second signal to other devices, and these devices performing perception-related measurements on the second signal, or the first device sending the above-mentioned second signal and the first device performing measurements, that is, the first device autonomously sends and receives measurements.

[0128] In the above optional implementation manner, since the above at least one perception measurement behavior is performed when the first information meets the preset condition, the overhead of the perception measurement can be saved.

[0129] As an optional implementation manner, the perception-related indicator includes at least one of the following:

[0130] Perception indicators related to received power;

[0131] Perceptual metrics related to interference or noise power;

[0132] A perceptual metric related to received power, and also to interference or noise power.

[0133] The above-mentioned received power-related perception indicators may include at least one of the following:

[0134] Perception indicators related to the received power of the target signal, and perception indicators related to the received power of the signal path of the target signal associated with the perception target. For example, the above-mentioned perception indicators related to received power include: a first indicator, the first indicator is used to indicate the received power of the signal path associated with the perception target in the signal path of the first signal, that is, the first indicator is used to indicate the received power of the signal path associated with the perception target in at least one signal path of the first signal.

[0135] The signal path associated with the aforementioned perception target may be a signal path affected by the perception target or a signal path passing through the perception target.

[0136] In one of the above optional embodiments, since the perception-related indicators include perception indicators related to received power, it is possible to determine whether to perform the perception measurement behavior based on received power, thereby making the performance of the perception measurement behavior more reliable. Furthermore, it is also possible to determine whether to perform the perception measurement behavior based on the received power of the signal path associated with the perception target. The received power of the signal path associated with the perception target can more intuitively reflect whether the perception measurement behavior is necessary. Therefore, using the above first indicator can make the perception measurement behavior more reliable.

[0137] In some embodiments, the first indicator may be a linear average value (in 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, 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 value. It should be noted that the embodiments of the present application do not limit the received power to a linear average value. For example, in some embodiments, the median received power, the minimum received power, or the maximum received power may also be taken.

[0138] The above-mentioned perception indicator related to interference or noise power may refer to the perception indicator being associated with at least one of interference and noise, such as a perception indicator associated with interference power, a perception indicator associated with noise power, or an interference indicator associated with both interference and noise power.

[0139] In the above optional implementation manner, since the perception-related indicators include perception indicators related to interference or noise power, interference or noise can be taken into consideration when determining whether to perform the perception measurement behavior, so that the perception measurement behavior is more reliable.

[0140] Optionally, the perception indicator related to the interference or noise power includes at least one of the following:

[0141] a second indicator, where the second indicator is the sum of a linear average of the powers of signal paths other than the signal path associated with the perception target in the channel response of the first signal on the target resource and a linear average of the interference or noise power from signals other than the first signal on the first resource; or, the second indicator is equal to the difference between the total received power and the first indicator, 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;

[0145] The above-mentioned other signal paths may be all or part of the signal paths in the first signal except the signal paths associated with the above-mentioned perception target.

[0146] The other signals other than the above-mentioned first signal may refer to all or part of the signals other than the first signal detected by the first device on the first resource.

[0147] The 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:

[0149] The 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:

[0150] a target resource, and at least one resource other than the target resource.

[0151] 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 resources configured by high-level signaling or resources that the first device predetermines need to detect or receive signals.

[0152] The above-mentioned interference or noise power includes the sum of interference power and noise power, interference power or noise power.

[0153] The total received power of the first device on the target resource may include the received power of signals of the serving cell and the non-serving cell on the target resource, adjacent channel interference power, and thermal noise power. The total received power may also be a linear average (in W) of the total received power of the first device on the target resource.

[0154] The power corresponding to the RSSI of the first device on the first resource may be total received power = RSSI*K1, where K1 is a coefficient and may be a protocol agreement or network configuration. In some implementations, the power corresponding to the RSSI may also be RSSI, i.e., total received power = RSSI.

[0155] The received power of the first signal refers to the reference signal received power (RSRP) of the first signal.

[0156] The above-mentioned second indicator is equal to the difference between the total received power and the first indicator, which can be expressed as second indicator = total received power - first indicator.

[0157] The third indicator equal to the difference between the total received power and the received power of the first signal can be expressed as third indicator = total received power - first signal received power.

[0158] The fourth indicator equal to the difference between the received power of the first signal and the first indicator can be expressed as fourth indicator=received power of the first signal-first indicator.

[0159] In the above embodiment, the second indicator can be used to consider interference or noise of signal paths other than the signal path associated with the perception target and signals other than the first signal when determining whether to perform the perception measurement behavior, thereby making the perception measurement behavior more reliable.

[0160] In the above implementation, the third indicator can be used to consider interference or noise of other signals besides the first signal when determining whether to perform the perception measurement behavior, which can make the perception measurement behavior more reliable.

[0161] In the above embodiment, the fourth indicator can be used to consider the power of other signal paths except the signal path associated with the sensing target when determining whether to perform the sensing measurement behavior, which can make the sensing measurement behavior more reliable.

[0162] The above-mentioned perception indicator related to the received power and also related to the interference or noise power means that the perception indicator is related to both the received power and the interference or noise power.

[0163] In the above optional implementation, since the perception-related indicators include perception indicators related to the received power and also related to the interference or noise power, it is possible to take the received power and the interference or noise into consideration when determining whether to perform the perception measurement behavior, so that the perception measurement behavior is more reliable.

[0164] In some embodiments, the perception indicator related to received power and also related to interference or noise power includes at least one of the following:

[0165] a fifth index, the fifth index being equal to a quotient obtained by dividing the first index by the second index;

[0166] a sixth index, the sixth index being equal to a quotient obtained by dividing the first index by the third index;

[0167] a seventh index, the seventh index being equal to a quotient obtained by dividing the first index by the fourth index;

[0168] An eighth indicator, wherein the eighth indicator is equal to the product of the quotient obtained by dividing the first indicator by the total received power and the target coefficient.

[0169] The first, second, third, and fourth indicators mentioned above refer to the above-mentioned embodiments and are not described in detail here. It should be noted that, when at least one of the fifth, sixth, seventh, and eighth indicators is included, the perception-related indicators in the embodiments of the present application may include or exclude the first, second, third, and fourth indicators.

[0170] The above target coefficient can be expressed as K2, such as the eighth indicator = K2*first indicator / total received power, K2 is a coefficient, and K2 can be specifically agreed upon in the protocol or configured on the network side.

[0171] In this implementation, the fifth indicator, the sixth indicator, the seventh indicator or the eighth indicator can be used to take the received power and the interference or noise into consideration when determining whether to perform the perception measurement behavior, so that the perception measurement behavior is more reliable.

[0172] In some implementations, the aforementioned perception indicator related to received power and also related to interference or noise power may further include at least one of the following:

[0173] Indicators related to the perceived signal to interference plus noise ratio (SINR), indicators related to the perceived signal to noise ratio (SNR), indicators related to the perceived signal to interference ratio (SIR), and indicators related to the perceived reference signal received quality (RSRQ).

[0174] As an optional implementation manner, the signal path associated with the perception target satisfies at least one of the following:

[0175] The parameter meets the first preset threshold, or the parameter is within the first preset range;

[0176] The parameters meet the preset modulation rules;

[0177] The parameter difference with the first signal path meets the second preset threshold, or the parameter difference with the first signal path is within the second preset range;

[0178] The parameter difference with the reference signal path meets the third preset threshold, or the parameter difference with the reference signal path is within a third preset interval.

[0179] The above parameters may include at least one of the following:

[0180] Amplitude, power, intensity, energy, phase, Doppler, delay, angle.

[0181] The above parameter difference may include at least one of the following:

[0182] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, delay difference, and angle difference.

[0183] 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 on the network side, or these preset thresholds or preset interval ranges are determined by the receiving device based on the perception prior information or perception requirements. The above-mentioned parameter meeting the first preset threshold may mean that the parameter exceeds or is equal to the first preset threshold, the above-mentioned parameter difference with the first-reaching signal path meets the second preset threshold may mean that the parameter difference with the first-reaching signal path exceeds or is equal to the second preset threshold, and the above-mentioned parameter difference with the reference signal path meets the third preset threshold may mean that the parameter difference with the reference signal path exceeds or is equal to the third preset threshold.

[0184] For example: if the perception 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 perception target; or for the traffic scene where the perception target is a car, the default vehicle speed is 40km / h to 120km / h, then the signal path within the corresponding speed range (Doppler range) is detected as the signal path associated with the perception target; or the distance between the perception target area and the perception signal transceiver needs to meet specific requirements, then the signal path within the corresponding time delay range is detected as the signal path associated with the perception target; or if the perception service is respiratory monitoring, the corresponding normal respiratory rate can be judged based on the person's gender and age (for example, 15 to 30 times / minute can be used as perception prior information, and the corresponding Doppler range can be calculated, 0.25 to 0.5Hz).

[0185] The first-arrival signal path may be a line-of-sight (LOS) path, specifically, the signal path of the first signal that first reaches the receiver. The reference signal path may be a signal path reflected by a known target, such as a reconfigurable intelligence surface (RIS), backscatter, or other known passive targets.

[0186] The preset modulation rule may be a protocol agreement or a network-side configuration. The specific modulation rule is a modulation rule of a tag, backscatter device, or RIS, that is, the path associated with the sensing target may be a signal path modulated and reflected by the tag, backscatter device, or RIS.

[0187] In one of the above optional implementations, the signal path associated with the perception target can be determined in multiple ways, which can not only improve the flexibility of determining the signal path associated with the perception target, but also improve the accuracy of determining the signal path associated with the perception target based on multiple methods.

[0188] In some implementations, before determining the signal path associated with the perceived target, a signal path set may be determined. The signal path set includes signal paths whose amplitude, power, intensity, or energy exceeds a certain threshold. As shown in FIG4 , the signal path set includes signal paths 0, 1, 2, and 3. The signal path associated with the perceived target is then determined based on at least one of the above items in the signal path set to reduce computational complexity.

[0189] The following example illustrates the calculation of indicators in the embodiment of the present application through an example. It should be noted that the calculation of each indicator in the embodiment of the present application is not limited, and the following example is only an example.

[0190] Calculation method of the first indicator 1:

[0191] 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 a channel response (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 path associated with the perception target in the target dimension. The power of the signal path associated with the perception target is then calculated as the first indicator. If the signal path associated with the perception target includes multiple signal paths, the sum of the powers of the multiple signal paths is calculated as the first indicator.

[0192] The target dimension includes one of the following:

[0193] Delay dimension;

[0194] Doplevi;

[0195] Azimuth dimension;

[0196] Pitch angle dimension;

[0197] A dimension that combines at least two of the following: delay, Doppler, azimuth, and elevation dimensions. For example, delay-Doppler, delay-Doppler-angle, etc.

[0198] For example, H(f) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and H(f) can be transformed into the delay dimension (target dimension) by performing an inverse Fourier transform on it. For another example, H(f, t) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and t = 0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., Orthogonal Frequency-Division Multiplexing). Multiplexing, OFDM) symbol index), then H(f,t) can be transformed into 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 it; for another example, H(f,t,s) is the channel response, where f=0,1,2,…,N-1 represents the frequency domain sampling point (such as the subcarrier index), t=0,1,2,…,M-1 represents the time domain sampling point (such as the OFDM symbol index), and s=0,1,2,…,P-1 represents the spatial domain sampling point (antenna index or port index), then H(f,t,s) can be transformed into 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 it.

[0199] The method for determining the signal path associated with the perception target (referred to as the perception path for short) in the channel response obtained by measuring the target signal may include the following:

[0200] Determine the signal path set. The signal paths in the signal path set include the paths whose amplitude, power, intensity, or energy exceeds a certain threshold among all paths after the channel response is transformed to the target dimension. For example, in Figure 4, signal paths 0, 1, 2, and 3 are the paths in the signal path set; 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 signal path set) is optional, and the signal path associated with the perception target can be determined based on the next step.

[0201] A signal path that meets a target condition is selected from the signal path set or from all signal paths of the target signal as the signal path associated with the perception target. The target condition includes at least one of the following:

[0202] The amplitude, power, intensity or energy of the signal path exceeds a preset threshold or is within a preset range, such as 5 times the noise threshold;

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

[0204] The signal path delay exceeds the preset threshold or is within the preset range;

[0205] The angle of the signal path exceeds the preset threshold or is within the preset range;

[0206] The difference in amplitude / power / intensity / energy between the signal path and the first-reach path (e.g., LOS path) or a reference path exceeds a preset threshold or is within a preset range. The reference signal path may be a signal path reflected by a known target (e.g., RIS / backscatter / other known passive targets).

[0207] The Doppler difference between the signal path and the first arrival path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0208] The delay difference between the signal path and the first arrival path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0209] The angle difference between the path and the first arrival path (such as LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0210] The amplitude, power, intensity, energy, or phase of the path satisfies a specific modulation rule. The specific modulation rule is the modulation rule of the tag / backscatter device or RIS. That is, the path associated with the perceived target can be a signal path modulated and reflected by the tag / backscatter device or RIS.

[0211] The above-mentioned target conditions may also be based on statistical results over a period of time; for example, the ratio of the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceeding a preset threshold or being within a preset range in a preset time window reaches a preset ratio, or the number of times the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceed a preset threshold or are within a preset range in a preset time window reaches a preset number of times;

[0212] The preset threshold or preset interval is sent by another device to the receiving device and is determined by the other device based on prior perception information or perception requirements. Alternatively, the preset threshold or preset interval may be a protocol agreement, or the preset threshold or preset interval is determined by the receiving device based on prior perception information or perception requirements.

[0213] The priori perception information or perception requirements include the following information:

[0214] Perception services or perception service types, such as detecting whether a target exists, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section area (Radar Cross Section Area), etc. Section, RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, population statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; the perception service type can be to classify multiple different perception services according to certain characteristics, for example, according to function, it can be divided into detection-type perception services (for example, including intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (motion recognition, identity recognition), etc., and can also be divided according to the range of perception (close-range perception, medium-range perception, long-range perception), according to the degree of perception fineness (coarse-grained perception, fine force perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc. If the sensing service is respiratory monitoring, the corresponding normal respiratory rate can be determined based on the person's gender and age (for example, male: 13-21 breaths / minute, female: 15-20 breaths / minute; adult: 12-20 breaths / minute, child: approximately 30-40 breaths / minute), which can be used as perception prior information;

[0215] Perception target area: refers to the location area of ​​the perception object, or the location area where imaging or environmental reconstruction is required; for example, the preset interval range of the time delay of the perception target correlation path is determined based on the approximate location / distance of the perception object;

[0216] Perception object type: Classifies the perception object according to its possible motion characteristics. Each perception object type contains information such as the typical perception object's motion speed range, motion acceleration range, and typical RCS range.

[0217] The number of perceived targets; for example, the camera perception result is used as a perception prior information to obtain the number of perceived targets.

[0218] For example, in Figure 4, signal paths 0, 1, 2, and 3 are paths in the signal path set, where signal paths 2 and 3 are perception paths that meet the target conditions (for example, their delays meet the preset threshold), and paths 0 and 1 are paths associated with other scatterers.

[0219] FIG4 is a schematic diagram of multiple signal paths of channel response in a target dimension (delay dimension, Doppler dimension, azimuth dimension, or elevation angle dimension), wherein the horizontal axis is the target dimension and the vertical axis is the normalized amplitude, power, intensity, or energy.

[0220] For frequency range 1, the reference point for the first metric 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 metric measured and reported by the receiving device cannot be lower than the metric of any single receiving channel. For frequency range 2, the first metric measured for a particular receiving channel requires measuring the combined signals of the multiple antenna elements corresponding to that receiving channel.

[0221] Calculation method 2 of the first indicator:

[0222] When calculating the received power of the signal path associated with the sensing target, it can also be the power of the signal path associated with the sensing target in the target dimension and The difference between is used as the first indicator, where N1 represents the number of signal paths associated with the perception target. It is the average power of multiple signal paths outside the signal path set in the target dimension.

[0223] Method 1 for calculating the received power of the target signal:

[0224] The received power of the target signal can be obtained by the receiving device, transforming the channel response (Channel Response) H(k) into the target dimension, determining the signal path set in the target dimension, and then calculating the power sum of all signal paths in the signal path set.

[0225] Method 2 for calculating the received power of the target signal:

[0226] The received power of the target signal can also be the sum of the power 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.

[0227] The total received power is calculated as follows:

[0228] Total received power:

[0229] Wherein, 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.

[0230] The calculation method of the second indicator is:

[0231] The channel response H(k) is processed by the first filter to obtain H filter1 (k), then according to H filter1 (k) and the target signal X(k) are used to calculate the received signal Y after the first filtering process filter1 (k), that is, Y filter1 (k)=H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the first filtering process. filter1 (k) Thus we get the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then calculate the second indicator:

[0232] The first filtering process is used to eliminate noise and interference in the target dimension and paths not associated with the perceived target. For example, the first filtering process sets the amplitude, power, intensity or energy of paths other than the path associated with the perceived target in FIG4 to zero. The channel response H after the first filtering process filter1 (k) does not include noise, interference, or paths associated with non-perceived targets, but only includes paths associated with perceived targets.

[0233] Calculation method 1 of the third indicator:

[0234] The channel response H(k) is processed by the second filter to obtain H filter2 (k), then according to H filter2 (k) and the target signal X(k) are used to calculate the received signal Y after the second filtering process filter2 (k), that is, Y filter2 (k)=H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the second filtering process. filter2 (k) Thus we get the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then calculate the third indicator:

[0235] The second filtering process can be a noise interference suppression process on the target dimension (for example, the amplitude, power, intensity or energy of the paths other than the signal path set in FIG4 is set to zero), or a minimum mean square error (MMSE) filter. The channel response H after the second filtering process is filter2(k) does not include noise and interference, and only includes the paths in the signal path set.

[0236] Calculation method 2 for the third indicator:

[0237] According to the average power of multiple signal paths outside the signal path set in the target dimension Calculate the third index P σ2 ,Right now Where N represents the number of sampling points in the target dimension.

[0238] It should be noted that if the receiving device determines that there are multiple sensing targets, or the receiving device obtains the number of sensing targets based on prior sensing information or sensing requirements, the following methods are available:

[0239] Method 1: Calculate the perception-related indicators (also called target indicators) for each perception target separately. For example, in Figure 4, the signal path associated with each perception target is determined separately, and then the perception-related indicators corresponding to each perception target are calculated separately. At this time, when calculating the second indicator corresponding to a perception target (such as perception target A), there are two methods: the second indicator of perception target A = total received power - the first indicator of perception target A; or the second indicator of perception target A = total received power - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B); similarly, there are two ways to calculate the fourth indicator: the fourth indicator of perception target A = the RSRP of the target signal - the first indicator of perception target A; or the fourth indicator of perception target A = the RSRP of the target signal - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B).

[0240] Method 2: Calculate a perception-related index for multiple perception targets. For example, in Figure 4, determine the signal path associated with any perception target, and then determine these signal paths as signal paths associated with the perception target. This is equivalent to treating multiple perception targets as a virtual perception target and then calculating the perception-related index corresponding to the virtual perception target.

[0241] As an optional implementation manner, the first information meeting a preset condition includes at least one of the following:

[0242] The perception-related indicators meet the preset indicator threshold requirements;

[0243] The perception measurement result meets the preset perception requirement;

[0244] The device information of the first device includes at least one of a movement direction, a movement speed, a position information or a direction information that meets a preset device threshold requirement.

[0245] Among them, the above-mentioned preset indicator threshold requirements, preset perception requirements and preset device threshold requirements can be protocol agreements or network-side configurations, or determined by the above-mentioned first device.

[0246] The above-mentioned perception-related indicator meeting the preset indicator threshold requirement may be that the perception-related indicator reaches the preset indicator threshold, or that the perception-related indicator is within the preset indicator threshold range.

[0247] The above-mentioned perception measurement results meet the preset perception requirements, which can be that the perception measurement results indicate whether the perception target or the signal path associated with the perception target is detected, or the perception measurement results (such as delay, Doppler, angle, etc.) are within the preset perception threshold range, or the target position coordinates calculated based on the perception measurement results are within the preset position range.

[0248] At least one of the movement direction, movement speed, location information, or orientation information included in the device information of the first device meeting the preset device threshold requirement may include at least one of the following:

[0249] The movement direction included in the device information of the first device matches the preset direction, or the movement direction is within a preset direction range;

[0250] The movement speed of the first device exceeds the preset speed threshold, or the movement speed is within the preset speed threshold range;

[0251] The location information of the first device is within a preset location range;

[0252] The orientation information of the first device matches a preset direction, or the angle between the orientation of the device and the direction of the area where the perception target is located is smaller than a preset threshold.

[0253] In the above optional implementation manner, 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 perception measurement.

[0254] In some embodiments, the first information further includes a communication-related indicator, wherein the communication-related indicator may include at least one of the following:

[0255] 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).

[0256] The first information meeting the preset condition also includes that the communication-related indicator meets the preset communication requirement, such as the communication-related indicator reaches a preset threshold, or the communication-related indicator is within a preset threshold range.

[0257] In this way, when performing perception measurement behavior, communication-related indicators must also meet preset communication requirements. For example, perception measurement behavior is performed when communication-related indicators indicate that the communication status is relatively good, further improving the reliability of perception measurement behavior.

[0258] As an optional implementation, the above method further includes:

[0259] The first device receives second information, where the second information includes at least one of the following:

[0260] Relevant information of the preset condition, configuration information of the first signal, configuration information of the second signal, measurement configuration information, perception requirement information, and perception prior information;

[0261] The second signal is a signal sent by the first device for sensing.

[0262] The above-mentioned second information may be the second information received by the first device and sent by the second device.

[0263] The relevant information of the preset condition may be relevant information used to determine the preset condition. For example, the relevant information of the preset condition may include at least one of the following:

[0264] The indication information of the perception-related indicator, the threshold information related to the perception-related indicator, the requirement information of the perception measurement result, and the requirement information of the device information.

[0265] The indication information of the above-mentioned perception-related indicators is used to indicate the perception-related indicators in the above-mentioned first information, that is, to indicate the perception-related indicators used to determine whether to perform the perception measurement behavior, such as indicating at least one of the first to eighth indicators in the above-mentioned embodiment as the perception-related indicators used to determine whether to perform the perception measurement behavior.

[0266] Since the second information includes relevant information about the preset condition, the first device determines the preset condition based on the relevant information, so that the first device and the device sending the second information have consistent understanding of the perception measurement behavior, thereby improving the perception measurement performance between the devices.

[0267] The configuration information of the first signal or the configuration information of the second signal may include at least one of the following:

[0271] The frequency domain resource length B, i.e., the frequency domain bandwidth, is inversely proportional to the range resolution. The frequency domain bandwidth B of each first signal or second signal is ≥ c / (2ΔR), where c is the speed of light and ΔR is the range resolution.

[0303] or,

This parameter is proportional to the maximum sensing distance. For example, it can be calculated by c / (2R max ) is calculated, R max is the maximum perception distance (belonging to the perception demand information), such as for the self-transmitted and self-received perception signal, R max Represents the maximum distance between the perceived signal transmission and reception point and the signal reflection point; in some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval, and c is the speed of light.
