[0067] In some embodiments, network-side devices and terminals may have perception capabilities in addition to communication capabilities. Perception capabilities refer to one or more devices with the ability to sense the position, distance, speed, and other information of a target object through the transmission and reception of wireless signals, or to detect, track, identify, and image a target object, event, or environment.

[0068] Table 1

[0069] It should be noted that the perception categories shown in Table 1 above are only examples, and the embodiments of the present application do not limit the categories of perception measurements.

[0070] 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. While transmitting information, the system can perceive information such as direction, distance, speed, and detect, track, and identify target devices or events.

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.

[0073] Sensing link 1: The base station transmits and receives sensing signals autonomously. In this mode, the base station sends sensing signals and obtains sensing results by receiving the echo of the sensing signals.

[0075] Perception link 3: Uplink air interface perception: In this mode, the base station receives the perception signal sent by the terminal and obtains the perception result.

[0076] Perception link 4: Downlink air interface perception: In this mode, the terminal receives the perception signal sent by the base station and obtains the perception result.

[0078] Perception link 6: Sidelink perception between terminals. For example, terminal 2 receives a perception signal sent by terminal 1 and obtains a perception result, or terminal 1 receives a perception signal sent by terminal 2 and obtains a perception result.

[0079] 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:

[0080] Target information is exchanged with a wireless signal sending device or a wireless signal measuring device (including a target terminal or a serving base station of the target terminal or a base station associated with a target area), wherein the target information includes a perception processing request, a perception capability, perception assistance data, a perception measurement quantity type, a perception resource configuration information, etc., to obtain the value of the target perception result or the perception measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; wherein the wireless signal can also be referred to as a perception signal.

[0081] 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. The perception method may include: wireless access network device A sends and wireless access network device B receives, or the wireless access network device sends and the terminal receives, or the wireless access network device A sends and receives by itself, or the terminal sends and the wireless access network device receives, or the terminal sends and receives by itself, or terminal A sends and terminal B receives, etc.

[0083] Manage the overall coordination and scheduling of resources required for sensing services, such as configuring sensing resources for wireless access network devices or terminals;

[0084] Data processing or calculation is performed on the values ​​of the perception measurement quantity to obtain the perception result. In addition, the perception result can be verified and the perception accuracy can be estimated.

[0085] In the following, in conjunction with the accompanying drawings, a method for feedback of perception measurement results, a method for receiving perception measurement results, an apparatus and a device provided in an embodiment of the present application are described in detail through some embodiments and their application scenarios.

[0086] Please refer to FIG3 , which is a flowchart of a method for feedback of perception measurement results provided by an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0087] Step 301: A first device measures a target signal to obtain a first perception measurement result.

[0088] The first device mentioned above may be a terminal or a network side device.

[0089] The target signal may be a signal sent by the first device to the second device, or a signal sent by the first device to the first device.

[0090] In an embodiment of the present application, when the second device sends the above-mentioned target signal, the second device may be a terminal or a network side device. When the second device does not send the target signal, the second device may be a core network element, such as a perception network function.

[0091] In an embodiment of the present application, the above-mentioned target signal may be a dedicated signal for sensing services, or a communication signal, such as a reference signal or a synchronization signal.

[0092] 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 sequence.

[0093] 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).

[0094] The synchronization signal may be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS).

[0095] 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.

[0096] The first perception measurement result may be a complete perception measurement result obtained through the above measurement, such as a perception measurement result including the time delay or Doppler information of all paths.

[0097] Step 302: The first device sends feedback information, where the feedback information satisfies at least one of the following conditions:

[0098] including second perceptual measurements;

[0099] providing feedback when a change in the first perception measurement result relative to a historical perception measurement result meets a first threshold requirement;

[0100] The second perception measurement result includes at least one of the following:

[0101] Change information of the first perception measurement result relative to historical perception measurement results;

[0102] The perception measurement result subset in the first perception measurement result includes a subset of the first perception measurement result that has changed relative to historical perception measurement results.

[0103] The above-mentioned first device sending feedback information may be the first device sending feedback information to the second device, or the first device sending the above-mentioned feedback information to the perception network function or other devices.

[0104] The above-mentioned historical perception measurement result refers to the perception measurement result that has been sent by the first device before executing step 301 or step 302, such as the perception measurement result most recently sent by the first device before step 301 (that is, the perception measurement result fed back last time), or the perception measurement result sent by a specific measurement or specific feedback before step 301. The above-mentioned historical perception measurement result may be a complete perception measurement result, or may be change information relative to other historical perception measurement results, or a subset of perception measurement results.

[0105] The change information of the above-mentioned first perception measurement result relative to the historical perception measurement result can be a change amount, such as a difference, and the difference can be a quantified result, or the change information of the above-mentioned first perception measurement result relative to the historical perception measurement result can indicate that there is a changed perception target or measurement amount.

[0106] The aforementioned perception measurement result subset refers to a subset of the multiple subsets included in the aforementioned first perception measurement result that has changed relative to historical perception measurement results, or a subset whose change exceeds a preset threshold. For example, if the first perception measurement result includes a subset of perception measurement results for multiple paths in the spectrum information, then the aforementioned perception measurement result subset is a subset of perception measurement results for the multiple paths that has changed relative to historical perception measurements. For another example, if the aforementioned first perception measurement result includes a subset of perception measurement results for multiple perception targets, then the aforementioned perception measurement result subset is a subset of perception measurement results for the multiple perception targets that has changed relative to historical perception measurements. For another example, if the first perception measurement result includes distance, Doppler, and angle measurement results, when the Doppler and angle do not change and only the distance changes, only the distance information may be reported, i.e., the aforementioned perception measurement result subset is the distance information.

[0107] The above-mentioned feedback when the change of the first perception measurement result relative to the historical perception measurement result meets the first threshold requirement can be understood as feedback only when the change of the first perception measurement result relative to the historical perception measurement result meets the first threshold requirement, and no feedback when the change of the first perception measurement result relative to the historical perception measurement result does not meet the first threshold requirement.

[0108] The first threshold requirement may be agreed upon by a protocol or configured on the network side, or determined by the first device, for example: the change exceeds the first threshold, or the change is within the first threshold range.

[0109] In an embodiment of the present application, the change of the first perception measurement result relative to the historical perception measurement result refers to the change between the same subset, or the change of the same measurement quantity, or the change of the perception target, such as the change between the same path in the spectral information, or the change between the same measurement quantity, such as the change between the same perception targets.

[0110] The above-mentioned feedback information fed back when the change in the first perception measurement result relative to the historical perception measurement result meets the first threshold requirement may include the above-mentioned second perception measurement, which can further reduce the perception measurement result feedback overhead, or may include the above-mentioned first perception measurement result, which can also reduce the perception measurement result feedback overhead.

[0111] The above feedback information that satisfies at least one of the above items can be understood as at least one of the following feedback methods:

[0112] The feedback information includes a second sensory measurement result;

[0113] Feedback the feedback information when a change in the first perception measurement result relative to a historical perception measurement result meets a first threshold requirement, wherein the feedback information is not limited to including the second perception measurement result, for example, it may be the first perception measurement result;

[0114] When a change in the first perception measurement result relative to a historical perception measurement result meets a first threshold requirement, the feedback information is fed back, where the feedback information includes the second perception measurement result.

[0115] In the embodiment of the present application, since information about a change in the first perception measurement result relative to a historical perception measurement result or a subset of the perception measurement results in the first perception measurement result is sent, the amount of feedback data can be reduced, thereby saving perception measurement result feedback overhead. Feedback is provided when the change in the first perception measurement result relative to the historical perception measurement result meets a first threshold requirement. This allows the perception measurement result to be fed back only when the change in the first perception measurement result relative to the historical perception measurement result meets the first threshold requirement, thereby saving perception measurement result feedback overhead.

[0116] As an optional implementation manner, the feedback information fed back when a change in the first perception measurement result relative to a historical perception measurement result meets a first threshold requirement includes the following:

[0117] the first perceptual measurement result;

[0118] the second sensory measurement result or the third sensory measurement result;

[0119] The third perception measurement result includes at least one of the following:

[0120] a measurement result of a first measurement quantity in the first perception measurement result, or change information of the first measurement quantity in the first perception measurement result relative to a historical perception measurement result;

[0121] The measurement result of the first perception target in the first perception measurement result, or the change information of the first perception target in the first perception measurement result relative to the historical perception measurement results.

[0122] In the embodiment of the present application, the measured quantities can be divided into the following categories:

[0123] The first-level measurement quantity (also known as the received signal / original channel information) includes at least one of the following:

[0130] The second threshold requirement may be agreed upon by a protocol, configured on the network side, or determined by the first device. For example, the change exceeds the second threshold, or the change is within the second threshold range. Furthermore, the second threshold requirement may be the same as or different from the first threshold requirement. For example, if the first threshold requirement includes threshold requirements for multiple measurement quantities, the second threshold requirement may be a subset of the first threshold requirement, or if the first threshold requirement may be a unified threshold requirement for multiple measurement quantities, the second threshold requirement may be the same as the first threshold requirement.

[0131] In this way, only the measurement results or change information of the measurement quantities whose changes meet the second threshold requirement need to be fed back, thereby further reducing the feedback overhead of the perception measurement results.

[0132] In other implementations, the first measurement quantity may also be a measurement quantity that has changed relative to a historical sensing measurement result, that is, the change is not required to meet the second threshold requirement.

[0133] The measurement result of the first measurement quantity may be a measurement result obtained by measuring the first measurement quantity, and the change information of the first measurement quantity relative to the historical perception measurement result may be a change difference between the measurement result of the first measurement quantity and the measurement result of the first measurement quantity in the historical perception measurement result.

[0134] In some embodiments, the first perception target includes:

[0135] The change in the measurement result relative to the historical perception measurement result meets the perception target required by the third threshold.

[0136] Among them, the above-mentioned third threshold requirement can be agreed upon by the protocol or configured on the network side, or determined by the above-mentioned first device. For example: the change exceeds the third threshold, or the change is within the range of the third threshold. In addition, the third threshold requirement and the above-mentioned first threshold requirement can be the same or different. For example: the above-mentioned third threshold requirement can include the threshold requirements of multiple perception targets, then the above-mentioned third threshold requirement can be a subset of the first threshold requirement, or the above-mentioned first threshold requirement can be a unified threshold requirement for multiple perception targets, then the above-mentioned third threshold requirement is the same as the above-mentioned first threshold requirement.

[0137] In this way, it is possible to feedback only the measurement results or change information of the perception targets whose change amounts meet the third threshold requirement, thereby further reducing the feedback overhead of the perception measurement results.

[0138] In other embodiments, the first perception target may also be a perception target that has changed relative to historical perception measurement results, that is, the change amount is not required to meet the third threshold requirement.

[0139] The measurement result of the above-mentioned first perception target can be the measurement result obtained by measuring the first perception target, and the change information of the above-mentioned first perception target relative to the historical perception measurement result can be the change difference between the measurement result of the first perception target and the measurement result of the first perception target in the historical perception measurement results.

[0140] In one of the above optional implementations, since the first perception measurement result is fed back when the change meets the first threshold requirement, or the second perception measurement result or the third perception measurement result is fed back, the perception measurement result feedback overhead can be saved. For example, the first device determines whether to report the first perception measurement result or the change of the first perception measurement result based on whether the change of the first perception measurement result relative to the historical perception measurement result meets the first threshold requirement. For example, when it is necessary to report measurement results corresponding to multiple measurement quantities, only the measurement results whose change of the measurement results meets the second threshold requirement, or the change relative to the historical perception measurement result, can be reported. Alternatively, when measurement results corresponding to multiple perception targets are detected, only the measurement results of the perception targets whose change relative to the historical perception measurement results meets the third threshold requirement, or the change relative to the historical perception measurement results, are reported.

[0141] As an optional implementation manner, the feedback information further includes: first indication information, where the first indication information is used to indicate whether the first perception measurement result includes a measurement result whose change amount meets the first threshold requirement, the second threshold requirement, or the third threshold requirement.

[0142] The first indication information may be one or more bits.

[0143] Because the first indication information indicates whether the first perception measurement result includes a measurement result whose change amount meets the threshold requirement, the receiving end of the feedback information can, after receiving the feedback information, determine based on the first indication information whether the first perception measurement result includes a measurement result whose change amount meets the threshold requirement, and then parse the feedback information based on whether the first perception measurement result includes a measurement result whose change amount meets the threshold requirement, thereby reducing the complexity of parsing the feedback information. If the indication indicates that the first perception measurement result includes a measurement result whose change amount meets the threshold requirement, the receiving end parses the feedback information according to the second perception measurement result.

[0144] Optionally, the first indication information is used to indicate whether the first perception measurement result includes the first measurement quantity or the measurement result of the first perception target.

[0145] The above indication may be given in a manner agreed upon in advance between the first device and the receiving end of the feedback information, or may be given in a manner agreed upon in a protocol.

[0146] Since the first indication information is used to indicate whether the first perception measurement result includes the first measurement quantity or the measurement result of the first perception target, the receiving end of the feedback information can parse the above feedback information based on the indication, thereby reducing the parsing complexity of the above feedback information.

[0147] Optionally, the first indication information includes at least one of the following:

[0148] First bit, second bit;

[0149] The first bit is used to indicate that the first perception measurement result includes a measurement result of the first measurement quantity or a second measurement quantity, and the second measurement quantity is a measurement quantity whose change amount relative to a historical perception measurement result does not meet a second threshold requirement;

[0150] The second bit is used to indicate that the first perception measurement result includes the measurement result of the first perception target or the second perception target, and the second perception target is a perception target whose measurement result change relative to the historical perception measurement result does not meet the third threshold requirement.

[0151] The first bit may be a first bitmap. For example, when the first perception measurement result includes distance, Doppler, and angle measurement results, if the Doppler and angle do not change and only the distance changes, only the distance information may be reported. In this way, a bitmap may be used to indicate the reporting status of the measurement quantity. For example, 3 bits may be used to indicate whether the distance, Doppler, and angle changes exceed corresponding thresholds to indicate which measurement quantities are reported. If the distance exceeds the corresponding threshold, the corresponding indication when only the distance is reported is '100', wherein '00' indicates that the Doppler and angle changes do not exceed the corresponding thresholds and are not reported in the feedback information. In this way, the feedback information overhead can be saved by using a bitmap.

[0152] The above-mentioned second bit can be a first bitmap. For example, when measurement results corresponding to multiple perception targets are detected, the feedback information only includes the measurement results of the perception targets whose change relative to the historical perception measurement results meets the third threshold requirement or the change relative to the historical perception measurement results. In this way, the bitmap can be used to indicate the reporting status of the measurement results of different perception targets. For example, if four perception targets are detected, and the change in the measurement result of the third target (for example, the change in distance or the change in position coordinates) exceeds the preset threshold, only the indication of the third perception target is reported as '0010', and the measurement results of the remaining perception targets are not reported in the feedback information. In this way, the overhead of feedback information can be saved by using the bitmap.

[0153] In the above embodiment, since the first bit is used to indicate that the first perception measurement result includes the measurement results of the first measurement amount and the second measurement amount, the second measurement amount is a measurement amount whose change in the measurement result relative to the historical perception measurement result does not meet the second threshold requirement. In this way, more perception measurement result information can be fed back to improve perception measurement result feedback performance.

[0154] In the above embodiment, since the second bit is used to indicate that the first perception measurement result includes the measurement results of the first perception target and the second perception target, the second perception target is a perception target whose measurement result change relative to the historical perception measurement result does not meet the third threshold requirement, this can feedback more information about the perception measurement result to improve the perception measurement result feedback performance.

[0155] As an optional implementation, the measurement result of the perception target may include a measurement result of a signal path associated with the perception target. For example, the measurement result of the first perception target includes:

[0156] A measurement result of a signal path associated with the first perception target in the target signal.

[0157] 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.

[0158] In this implementation, the measurement result of the signal path associated with the first perception target can be fed back, which can further reduce the perception measurement result feedback overhead.

[0159] It should be noted that, in the embodiment of the present application, the measurement result of the above-mentioned first perception target is not limited to the measurement result of the signal path associated with the first perception target in the target signal. For example, in some embodiments, the measurement result of the above-mentioned first perception target may also be the perception measurement result of the area where the perception target is located.

[0160] As an optional implementation manner, the signal path associated with the perception target satisfies at least one of the following:

[0161] The parameter meets the first preset threshold, or the parameter is within the first preset range;

[0162] The parameters meet the preset modulation rules;

[0163] 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;

[0164] 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.

[0165] The above parameters may include at least one of the following:

[0166] Amplitude, power, intensity, energy, phase, Doppler, delay, angle;

[0167] The above parameter difference may include at least one of the following:

[0168] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, delay difference, and angle difference.

[0169] 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.

[0170] 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).

[0171] The first-arrival signal path can be a line-of-sight (LOS) path, specifically, the path of the target signal that first reaches the receiver. The reference signal path can be a signal path reflected by a known target, such as a reconfigurable intelligence surface (RIS), backscatter, or other known passive targets.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] A first device (e.g., a terminal) performs channel estimation based on a transmitted target signal X(k) and a 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 a resource unit index and K is the number of resource units. After obtaining the channel response H(k), the first device transforms it to the target dimension and determines a signal path associated with the perceived target in the target dimension.

[0177] The target dimension includes one of the following:

[0178] Delay dimension;

[0179] Doplevi;

[0180] Azimuth dimension;

[0181] Pitch angle dimension;

[0182] A dimension that combines at least two of the following: delay, Doppler, azimuth, and elevation dimensions. For example, delay-Doppler, delay-Doppler-angle, etc.

[0183] 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., OFDM symbol index), and H(f, t) can be transformed into the time domain dimension by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension. Delay-Doppler dimension (target dimension); for another example, H(f,t,s) is the channel response, where f=0,1,2,…,N-1 represents the frequency domain sampling point (e.g., subcarrier index), t=0,1,2,…,M-1 represents the time domain sampling point (e.g., 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 inverse Fourier transform along the frequency domain dimension, Fourier transform along the time domain dimension, and Fourier transform along the antenna domain dimension.

[0184] 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:

[0185] 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.

[0186] 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:

[0187] 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;

[0188] The Doppler of the signal path exceeds the preset threshold or is within the preset range;

[0189] The signal path delay exceeds the preset threshold or is within the preset range;

[0190] The angle of the signal path exceeds the preset threshold or is within the preset range;

[0191] 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).

[0192] 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;

[0193] 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;

[0194] The angle difference between the first arrival path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0195] The amplitude, power, intensity, energy or phase of the path meets the 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 the signal path modulated and reflected by the tag / backscatter device or RIS.

[0196] 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;

[0197] 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.

[0198] The priori perception information or perception requirements include the following information:

[0199] Perception services or perception service types, such as detecting the presence of a target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section RCS (Radar Cross 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;

[0200] 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;

[0201] 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.

[0202] 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.

[0203] For example, Figure 4 shows a schematic diagram of multiple signal paths in the channel response in the target dimension (delay, Doppler, azimuth, or elevation). The horizontal axis represents the target dimension, and the vertical axis represents the normalized amplitude, power, intensity, or energy. As shown in Figure 4, signal paths 0, 1, 2, and 3 are signal paths in the signal path set. Signal paths 2 and 3 are sensing paths that meet the target condition (e.g., their delay meets a preset threshold), i.e., signal paths associated with the sensing target. Paths 0 and 1 are signal paths associated with other scatterers.

[0204] As an optional implementation manner, when the first perception measurement result includes spectrum information, the perception measurement result subset includes:

[0205] The measurement result of the first path in the spectrum information; or

[0206] a measurement result of the first path in the spectrum information, and a measurement result of the second path in the spectrum information;

[0207] The first path is a path where the measurement result changes relative to the historical perception measurement result, and the second path includes a path within at least one resolution unit adjacent to the first path.

[0208] The spectrum information may include at least one of the following:

[0209] Delay power spectrum, distance power spectrum, Doppler power spectrum, angle power spectrum.

[0210] The above-mentioned angular power spectrum may include an azimuth angle power spectrum or an elevation angle power spectrum.

[0211] Alternatively, the spectrum information may include spectrum information of at least two items of a delay power spectrum, a range power spectrum, a Doppler power spectrum or an angle power spectrum, such as a delay-Doppler spectrum.

[0212] The above-mentioned first path is the path in the above-mentioned spectrum information that has changed relative to the spectrum information in the historical perception measurement results. For example: the spectrum information in the first perception measurement result includes perception measurements of multiple paths, and the above-mentioned first path is the path in which the measurement results of these multiple paths have changed relative to the historical perception measurement results, that is, the measurement result of the first path in the above-mentioned first perception measurement result is different from the measurement of the first path in the historical perception measurement results.

[0213] In some implementations, the first path may be a path where a change in a measurement result relative to a historical perception measurement result meets a fourth threshold requirement, which can further reduce the perception measurement result feedback overhead.

[0214] The second path may include one or more resolution units adjacent to the first path, for example, resolution units adjacent to the left and right of the first path, such as a path within at least one resolution unit adjacent to the left of the first path, and a path within at least one resolution unit adjacent to the right of the first path. For example, for the delay power spectrum, the feedback information reports the results of the path within a range of ±X adjacent resolution units, centered on the path where the change in the delay power spectrum occurs. The resolution unit is the minimum delay granularity of the delay power spectrum, and the resolution unit is associated with the perceptual resolution. The value of X is determined by protocol agreement, network configuration, or the first device.

[0215] In the above-mentioned optional implementation manner, since the perception measurement result subset includes the measurement results of the first path in the spectrum information, the perception measurement result feedback overhead can be further reduced, and the perception measurement result subset includes the measurement results of the first path in the spectrum information and the measurement results of the second path in the spectrum information. In this way, as many measurement results as possible can be reported while reducing the perception measurement result feedback overhead, so as to improve the measurement result feedback performance.

[0216] As an optional implementation manner, the change information of the first perception measurement result relative to the historical perception measurement includes at least one of the following:

[0217] a difference between the first perception measurement result and the historical perception measurement result;

[0218] The difference information of the first perception measurement result relative to the historical perception measurement result in spectrum information.

[0219] The above spectrum information can be found in the corresponding description of the above implementation manner, which will not be repeated here.

[0220] The above-mentioned difference may be a quantized difference, such as a quantized difference between the first perception measurement result and the historical delay / distance / Doppler / angle measurement result. For example, as shown in Figure 5, the left side of Figure 5 represents the delay power spectrum obtained from the previous measurement, and the right side of Figure 5 represents the delay power spectrum in the first perception measurement result. The change information of the first perception measurement result relative to the historical perception measurement may be the delay difference corresponding to the perception target in the two measurements, that is, 91.58-61.05=30.53 (ns). The reported result may be the quantized result of the above-mentioned delay difference.

[0221] The above-mentioned difference information can be a resolution unit offset in the spectrum information, and the change information of the first perception measurement result relative to the historical perception measurement can be a position in the spectrum information offset by ±X distance / Doppler / angle resolution units relative to the historical delay / distance / Doppler / angle.

[0222] Alternatively, the above-mentioned difference information can be the difference in the coordinate index corresponding to the perception target, for example: the position index value corresponding to the reported perception target path in the delay dimension, for example, as shown in Figure 6, the left side of Figure 6 represents the delay power spectrum obtained in the last measurement, and the right side of Figure 6 represents the delay power spectrum in the first perception measurement, where the horizontal axis is the sampling index value of the delay dimension, then the change information of the first perception measurement result relative to the historical perception measurement can be the difference in the coordinate index corresponding to the perception target in the two measurements, that is, 10-7=3.

[0223] In the above optional implementation manner, the difference relative to the historical perception measurement result or the difference information in the spectrum information relative to the historical perception measurement result can be fed back to improve the flexibility of the measurement result feedback.

[0224] As an optional implementation manner, the feedback information further includes at least one of the following:

[0225] second indication information for indicating whether the feedback information includes change information relative to historical perception measurement results;

[0226] The third indication information is used to indicate the historical perception measurement result.

[0227] The second indication information can indicate to the receiver of the feedback information whether the feedback information reported is change information relative to the historical perception measurement results, so that the receiver of the feedback information can parse the feedback information accordingly and reduce the complexity of parsing the feedback information by the receiver of the feedback information.

[0228] The third indication information is used to indicate the specific historical perception measurement result relative to the feedback information, such as indicating the change relative to which reported perception measurement result. For example, an associated ID can be assigned to at least one measurement or reporting behavior. If the first perception measurement result includes the change of the perception measurement result relative to the historical perception measurement result, the measurement / reporting identifier can be used to indicate that the change is the change of the current perception measurement result relative to a certain past measurement / reported perception measurement result. The third indication information can improve the accuracy of the perception measurement feedback.

[0229] It should be noted that, in the embodiment of the present application, the above-mentioned second indication information or third indication information may also be a protocol agreement or pre-configuration.

[0230] As an optional implementation, the method further includes:

[0231] The first device receives first information, where the first information includes at least one of the following:

[0232] The target signal configuration information, measurement identification information, reporting identification information, measurement resource information, perception measurement amount, reporting configuration, perception measurement result requirement information, perception measurement result validity time information, perception requirement information, and perception prior information.

[0233] The configuration information of the target signal may include at least one of the following:

[0234] Signal identifier (ID), used to distinguish different signal resources;

[0235] Signal usage indicates whether the signal is used for communication (e.g., channel measurement, channel estimation, synchronization, or carrying data information), for sensing, or for both communication and sensing. Specifically, it may also indicate which sensing service the signal is used for, or which type of sensing service the signal is used for.

[0236] Waveforms, such as Orthogonal Frequency Division Multiplex (OFDM), Single-Carrier Frequency-Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Chirp, Frequency Modulated Continuous Wave (FMCW), pulse signals, etc.

[0237] Subcarrier spacing, for example, the subcarrier spacing of the OFDM system is 30KHz.

[0238] The guard interval is the time interval from the moment the signal ends to the moment the latest echo signal of the signal is received; this parameter is proportional to the maximum perception distance; for example, it can be calculated by c / (2R max ) is calculated, R max is the maximum perception distance (belonging to the perception demand information), for example, for the self-transmitted and self-received perception signal, R max Represents the maximum distance between the perceived signal receiving and transmitting point and the signal transmitting point; in some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval; c is the speed of light.

[0239] The starting frequency domain position, i.e., the starting frequency point, can also be the starting resource element (RE) or resource block (RB) index;

[0240] The starting time domain position, i.e. the starting time point, can also be the starting symbol index, time slot index, or frame index;

[0241] The ending frequency domain position, i.e., the ending frequency point, can be represented by the ending RE and RB index;

[0242] The termination time domain position, i.e., the termination time point, can be represented by the termination RE and RB index;

[0243] Frequency domain resource length, i.e., frequency domain bandwidth, is inversely proportional to the range resolution. The frequency domain bandwidth of each target signal is B ≥ c / (2ΔR), where c is the speed of light and ΔR is the range resolution.

[0244] The time domain resource length, also called the burst duration, is inversely proportional to the Doppler resolution.

[0245] Frequency domain resource spacing, which represents the spacing between adjacent signal frequency domain resource units, can be expressed as the number of REs or RBs, or as a density value. For example, Density = 1 means that there is one RE in each RB used to carry the signal. The frequency domain resource spacing is inversely proportional to the maximum unambiguous distance / delay. For OFDM systems, when subcarriers are continuously mapped, the frequency domain spacing is equal to the subcarrier spacing.

[0246] The time domain resource interval is the time interval between two adjacent signal resource units. The time domain resource interval is associated with the maximum unambiguous Doppler frequency shift or the maximum unambiguous speed; it can also be the signal time domain transmission period.

[0247] Time domain resource characteristics: periodic transmission, semi-continuous transmission, and aperiodic transmission.

[0248] The signal power, for example, takes a value from -20dBm to 23dBm at intervals of 2dBm.

[0249] Sequence information, including sequence type information (ZC sequence, PN sequence, etc.), sequence generation method, sequence length, etc.

[0250] Signal direction, angle information or beam information of the signal transmission.

[0251] Quasi co-location (QCL) relationship, for example, the sensing signal includes multiple resources, each resource is associated with a synchronization signal block (SSB) QCL, and the QCL includes Type A, B, C or D.

[0252] The cyclic prefix (CP) information may include the CP type or the CP length, where the CP type may include a normal cyclic prefix (NCP), an extended cyclic prefix (ECP), or a newly designed CP dedicated to perception measurement.

[0253] The above-mentioned measurement identification information can be used to indicate the identification of the measurement corresponding to the first perception measurement result.

[0254] The above-mentioned reporting identification signal can be used to indicate the reporting identification corresponding to the first perception measurement result.

[0255] The above-mentioned measurement resource information may be a measured signal resource indication, such as a signal identifier, used to indicate the measured resource.

[0256] For the above-mentioned perception measurement amount, please refer to the corresponding description of the above-mentioned embodiment, which will not be repeated here.

[0257] The reporting configuration is used to indicate reporting related information of the feedback information. For example, the reporting configuration includes at least one of the following:

[0258] An indication of whether to report changes relative to historical perception measurements;

[0259] an indication of said historical sensory measurements;

[0260] Threshold requirement information for changes in historical sensory measurement results;

[0261] Reported resource allocation;

[0262] Reporting cycle;

[0263] Trigger conditions for reporting.

[0264] The indication of the historical perception measurement result is used to indicate that the change amount of the perception measurement result is the change amount of the first perception measurement result relative to which previously reported perception measurement result.

[0265] The threshold requirement information of the change amount of the historical perception measurement results may include relevant thresholds such as the first threshold requirement, the second threshold requirement, and the third threshold requirement.

[0266] The triggering conditions for reporting may include at least one of the following:

[0267] Events of entering a specific area (e.g., a neighborhood);

[0268] Events arriving at a specific time;

[0269] An event where a certain type of measurement signal reaches a certain threshold;

[0270] Events where the device moves more than some predefined (linear) distance from its previous position;

[0271] An event where the device orientation changes by more than some predefined angle, where the device orientation can refer to the orientation of a specific component on the device, such as the orientation of a sensor, antenna, or screen;

[0272] Events where the device's movement speed exceeds some predefined speed threshold;

[0273] An event in which changes in environmental information (such as temperature, humidity, or light intensity) measured by device sensors exceed a certain range.

[0274] The above reporting configuration enables the first device to perform more accurate reporting.

[0275] The requirement information for the perception measurement result may include a range of the perception measurement result. If the requirement is met, the perception measurement result is valid; otherwise, it is invalid. This allows the feedback information to be sent only when the requirement information for the first perception measurement result is met, further reducing the perception measurement result feedback overhead.

[0276] The valid time information of the above-mentioned perception measurement results can be a requirement for the calculation delay of the perception measurement results. If the requirement is exceeded, it means that the perception measurement results are invalid. In this way, the above-mentioned feedback information can be sent only when the first perception measurement result meets the required information, thereby further reducing the perception measurement result feedback overhead.

[0277] The perception requirement information is used to represent the perception requirement information corresponding to the first perception measurement result, and the perception prior information can be used to assist the first device in calculating the prior information of the first perception measurement result. In this way, the perception performance of the first device can be improved by using the perception requirement information or the perception prior information.

[0278] In some embodiments, the perceived demand information may include at least one of the following:

[0279] Perception services or perception service types, perception services may include at least one of the following: detection of target presence, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, RCS detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, breathing 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 may be to classify multiple different perception services according to certain characteristics, for example, to classify them into detection-type perception services according to their functions. Perception services (such as intrusion detection and fall detection), parameter estimation perception services (distance, angle, speed calculation), recognition perception services (motion recognition and identity recognition), etc.; or they can be divided into, for example, target detection and tracking perception services (including target presence, target distance measurement / distance measurement / angle measurement / positioning / trajectory tracking), environmental monitoring perception services (including rainfall detection and flood monitoring), motion detection perception services (including gesture / motion recognition, breathing / heartbeat detection, fall detection), etc.; they can also be divided according to the range of perception (close-range perception, medium-range perception, and long-range perception), according to the degree of perception refinement (coarse-grained perception, fine force perception, etc.), according to the perception scene (indoor, outdoor, home, factory, highway, etc.), according to power consumption / energy consumption, according to resource occupancy, etc.

[0280] The perception target area may refer to the location area where the perception object may exist, or the location area where imaging or environment reconstruction is required;

[0281] The type of the perceived object can be used to classify the perceived object according to its possible motion characteristics. Each perceived object type contains information such as the motion speed, motion acceleration, and typical RCS of a typical perceived object.

[0282] Perception QoS can be a performance indicator for perceiving a target area or a perceiving object, including at least one of the following:

[0283] Perception resolution, which can be divided into: ranging resolution, angle resolution, velocity resolution, imaging resolution, etc.;

[0284] Perception accuracy can be divided into: ranging accuracy, angle measurement accuracy, speed measurement accuracy, positioning accuracy, etc.

[0285] Perception range, which can be divided into: ranging range, speed measurement range, angle measurement range, imaging range, etc.;

[0286] Perception latency, such as the time interval from the sending of a perception signal to the acquisition of a perception result, or the time interval from the initiation of a perception request to the acquisition of a perception result;

[0287] Perception update rate, such as the time interval between two consecutive perception executions and the acquisition of perception results;

[0288] Detection probability, such as the probability of correctly detecting the perceived object when it is present;

[0289] False alarm probability, i.e. the probability of incorrectly detecting a perceived target when the perceived target does not exist;

[0290] The maximum number of targets that can be perceived.

[0291] It should be noted that, in some implementations, at least one item included in the above-mentioned first information may also be a protocol agreement or a network-side configuration, which is not limited to this.

[0292] As an optional implementation manner, after the first device sends the feedback information, the method further includes:

[0293] The first device receives second information, where the second information is used to adjust at least one of the following:

[0294] Configuration information of the target signal;

[0295] Report configuration.

[0296] The second information is the second information generated and sent by the receiver of the feedback information (eg, the second device) based on the feedback information after receiving the feedback information.

[0297] The above-mentioned adjustment of the configuration information or reporting configuration of the target signal can be an adjustment based on the purpose of saving overhead or improving reporting accuracy. For example, the adjustment of the configuration information of the target signal includes adjusting the time domain burst interval of the target signal. For example, when the change in the measurement result is small and does not meet the threshold requirement, the first device is instructed not to report (multiple times) to save reporting overhead; or when the change in reporting (or multiple reports) is 0, the time domain burst interval in the target signal configuration is increased, or the reporting period in the reporting configuration is increased to improve reporting accuracy. Alternatively, the above-mentioned adjustment of the configuration information of the target signal may include adjusting the frequency domain resource position or time domain resource position or power of the target signal. Alternatively, adjusting the reporting configuration may include adjusting the content of the report, etc.

[0298] In this implementation, the configuration or reporting configuration of the target signal can be adjusted through the second information, so that the first device can measure the target signal or report feedback information based on the adjusted content, thereby obtaining better perceptual measurement performance.

[0299] In the embodiments of the present application, the following situations may be included:

[0300] In case 1, the first device sends and receives the target signal by itself for measurement, and the first device reports feedback information to the second device or the perception network function;

[0301] Case 2: The second device sends the target signal, the first device receives the target signal and performs perception measurement, and the first device reports feedback information to the second device or the perception network function.

[0302] The first device and the second device may be wireless access network devices, terminals or perception network functions.

[0303] Among them, the signaling transmission between the wireless access network equipment and the terminal, and between different terminals is 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 can 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 can be forwarded to the wireless access network through the N2 interface by AMF; or the core network perception network function sends it to the UPF, and the UPF sends it to the wireless access network through the N3 interface; or it is sent to the wireless access network (such as a base station) through a newly defined interface; the signaling transmission between wireless access network devices can be through the Xn interface.

[0304] In an embodiment of the present application, a first device measures a target signal to obtain a first perception measurement result. The first device sends feedback information, where the feedback information satisfies at least one of the following: includes a second perception measurement result; and is fed back when a change in the first perception measurement result relative to a historical perception measurement result meets a first threshold requirement. The second perception measurement result includes at least one of the following: information about a change in the first perception measurement result relative to the historical perception measurement result; and a subset of perception measurement results within the first perception measurement result, the subset comprising a subset of the first perception measurement result that has changed relative to the historical perception measurement result. Because only information about the change in the first perception measurement result relative to the historical perception measurement result or a subset of the perception measurement results within the first perception measurement result is sent, the amount of feedback data can be reduced, thereby saving perception measurement result feedback overhead. Feedback is provided when a change in the first perception measurement result relative to the historical perception measurement result meets the first threshold requirement. This ensures that the perception measurement result is fed back only when the change in the first perception measurement result relative to the historical perception measurement result meets the first threshold requirement, thereby saving perception measurement result feedback overhead.

[0355] It should be noted that this embodiment is an implementation of the second device corresponding to the embodiment shown in Figure 3. Its specific implementation can refer to the relevant description of the embodiment shown in Figure 3. In order to avoid repeated description, this embodiment will not be repeated.

[0356] The following examples illustrate the method provided in the embodiments of the present application:

[0357] Example:

[0358] This embodiment mainly describes the process of indicating and reporting the change in the perception measurement result, including the following steps:

[0359] Step 1: The first device receives the target signal and performs measurement, and sends feedback information to the second device (the sending device of the target signal or the perception network function or other device).

[0360] The feedback information includes at least one of the following:

[0361] An indicator of whether it is a change in the perception measurement result, that is, whether the content reported in the feedback information is the perception measurement result or the change in the perception measurement result relative to the historical measurement result;

[0362] The change in the perception measurement result is an identifier of the change in the current perception measurement result relative to the previously reported perception measurement result; by default, the change in the measurement result relative to the last reported measurement result is reported, or an indication of the change in the measurement result relative to the last reported measurement result is given. For example, an associated ID may be assigned to at least one measurement or reporting behavior. If the feedback information includes the change in the perception measurement result relative to the historical perception measurement result, the measurement / reporting identifier may be used to indicate that the change is the change in the current perception measurement result relative to a certain measurement / reported perception measurement result in the past;

[0363] An indication of whether to include specific perception measurement results, i.e., the feedback information only includes measurement results whose changes meet the threshold requirements: if the change exceeds the preset threshold, the first perception measurement result or the change of the measurement result relative to the historical measurement result is reported; if the change does not exceed the preset threshold, the first perception measurement result or the change of the measurement result relative to the historical measurement result is not reported. Specifically, it includes at least one of the following:

[0364] Whether the measurement result corresponding to a specific perceptual measurement quantity is included, that is, the feedback information only includes measurement results whose measurement result changes meet the threshold requirements (or their changes relative to historical measurement results). For example, when reporting distance, Doppler, and angle measurement results, if the Doppler and angle do not change and only the distance changes, only the distance information can be reported. Specifically, a bitmap can be used to indicate the measurement quantity reporting status. For example, 3 bits are used to indicate whether the distance, Doppler, or angle changes exceed the threshold, that is, whether to report. Accordingly, when only the distance is reported, the corresponding indication is '100'.

[0365] Whether the measurement result corresponding to a specific perception target (or a signal path associated with a specific perception target) is included. That is, when the measurement results corresponding to multiple perception targets (signal paths associated with multiple perception targets) are detected, the feedback information only includes the measurement results of the perception targets (signal paths associated with the perception targets) whose change relative to the historical measurement results meets the threshold requirement (or their change relative to the historical measurement results). Specifically, a bitmap can be used to indicate the reporting status of the measurement results of different perception targets (paths). For example, if four perception targets (signal paths associated with perception targets) are detected, and the change in the measurement result of the third target (such as the change in distance or position coordinates) exceeds the preset threshold, the indication that only the third perception target (signal path associated with perception target) is reported is '0010'.

[0366] The change relative to the historical perception measurement result or the second perception measurement result. The second perception measurement result is the value of the perception measurement quantity, such as delay / distance, Doppler, angle, etc. For dual-base perception, the perception measurement result can also be the delay difference / distance difference, Doppler difference, angle difference, etc. between the perception path and the reference path. If the second perception measurement result includes spectral information, such as at least one of the delay power spectrum, distance power spectrum, Doppler power spectrum, and angle (including azimuth and / or pitch angle) power spectrum, or joint spectral information of at least two of the delay / distance, Doppler, and angle, such as the delay-Doppler spectrum, the second perception measurement result can be a subset of the spectral information determined based on the change in the measurement result, and the subset includes at least the part of the spectral information that has changed (or the amount of change exceeds a preset threshold) relative to the previously reported spectral information. For example, the entire delay power spectrum is reported based on historical measurement results. When reporting in the feedback information, the path where the delay power spectrum changes is taken as the center, and the results within the range of adjacent ±X resolution units are reported. The resolution unit is the minimum delay granularity of the delay power spectrum, which is associated with the perception resolution.

[0367] The change relative to the historical perception measurement result can be the difference (quantized result) relative to the historical delay / distance / Doppler / angle measurement result, or the change relative to the historical perception measurement result is the position of the historical delay / distance / Doppler / angle corresponding to the spectrum information offset by ±X distance / Doppler / angle resolution units.

[0368] For example, as shown in FIG5 , the delay power spectrum (left) obtained in the last measurement and the delay power spectrum (right) obtained in the current measurement are shown. The change in the perception measurement result can be the delay difference corresponding to the perception target (perception path) in the two measurements, that is, 91.58-61.05=30.53 (ns), and the reported result can be the quantified result of the above delay difference. Alternatively, the position index value of the signal path associated with the perception target corresponding to the delay dimension is directly reported. For example, FIG6 shows the delay power spectrum (left) obtained in the last measurement and the delay power spectrum (right) obtained in the current measurement, where the horizontal axis is the sampling index value of the delay dimension. The change in the perception measurement result can be the difference in the coordinate index corresponding to the perception target (perception path) in the two measurements, that is, 10-7=3.

[0369] Step 2: Before the first device sends the feedback information, the first device also includes obtaining first information and measuring the target signal based on the first information. The first information includes at least one of the following:

[0370] The target signal configuration information, measurement identification information, reporting identification information, measurement resource information, perception measurement amount, reporting configuration, perception measurement result requirement information, perception measurement result validity time information, perception requirement information, perception prior information,

[0371] The first information may be sent from the second device to the first device. It should be noted that each item in the first information may be sent separately, or at least two items may be sent using the same signaling.

[0372] Step 3: After receiving the feedback information sent by the first device, the second device may further adjust the target signal configuration or reporting configuration based on the feedback information and send it to the first device. Adjusting the target signal configuration includes adjusting the time domain burst interval of the target signal. For example, when the change in the measurement result is small and does not meet the threshold requirement, the first device does not report (multiple times), or the change in the (multiple) reports is 0, the second device increases the time domain burst interval in the target signal configuration or increases the reporting period in the reporting configuration.

[0373] The method provided in the embodiments of the present application can implement the reported feedback information including at least one of the following: reporting a change in the current measurement result relative to a historical measurement result (e.g., a previously reported measurement result); determining whether to report the measurement result or the change in the measurement result based on whether the change in the current measurement result relative to the historical measurement result exceeds a preset threshold; and reporting a subset of the measurement results based on the change in the current measurement result relative to the historical measurement result. This can effectively reduce measurement result feedback overhead and assist a party receiving the perception measurement results in adjusting the configuration of the perception measurement signal, thereby achieving better perception measurement performance.

[0374] The perception measurement result feedback method provided in the embodiment of the present application may be executed by a perception measurement result feedback device.
