[0046] Table 1
[0047] 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.
[0048] 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.

[0050] In the embodiment of the present application, depending on the difference between the sending node and the receiving node of the perception signal, the six types of perception links shown in Figure 2 may be included but not limited to. 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.

[0056] 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.
[0057] 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.
[0058] 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:
[0059] 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.
[0060] 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.
[0061] The perception device serving the perception service is determined based on factors such as the type of perception service, information about the perception service consumer, required perception QoS requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device. The perception device includes a wireless signal sending device or a wireless signal measuring device.

[0063] The sensory measurement values are processed or calculated to obtain sensory results. Furthermore, the sensory results are verified and the sensory accuracy is estimated.
[0064] The following describes in detail a method, apparatus, and device for feedback of perception measurement results provided by the embodiments of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.
[0065] 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:
[0066] Step 301: A first device performs measurement based on a target signal.
[0067] The first device may be a terminal or a wireless access network device.
[0068] The first device performing measurement based on the target signal may be that the first device receives the target signal and performs measurement, that is, the first device is a receiving device of the target signal.
[0069] The first device performing measurement based on the target signal may be that the first device sends the target signal and performs measurement, that is, the first device may be a sending device of the target signal, such as a device that transmits and receives the signal autonomously.
[0070] 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.
[0071] 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.
[0072] 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).
[0073] The synchronization signal may be a primary synchronization signal (PSS) or a secondary synchronization signal (SSS).
[0074] 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.
[0075] Step 302: The first device determines validity of a perception measurement result based on a perception-related indicator associated with the target signal, where the perception measurement result is a perception measurement result measured based on the target signal.
[0076] The perception-related indicator associated with the target signal may be a perception-related indicator obtained by the first device during a measurement process based on the target signal, or may be a perception-related indicator obtained by the first device during a process of receiving the target signal.
[0077] The aforementioned perception-related indicators refer to perception-related indicators, such as indicators that affect perception targets or indicators that affect perception measurements.
[0078] Since the validity of the perception measurement result is determined based on the perception-related indicator associated with the target signal, the validity of the perception measurement result can be improved more accurately, because the validity of the perception measurement result is closely related to the perception-related indicator.
[0079] The validity of the above-mentioned perception measurement result may be that the perception measurement result is invalid, the perception measurement result is valid, the validity level of the perception measurement result, or the invalidity level of the perception measurement result.
[0080] Step 303: The first device indicates the validity of the perception measurement result to the second device.
[0081] The above-mentioned first device indicating the validity of the perception measurement result to the second device may be that the first device sends feedback information to the second device, and the feedback information indicates the validity of the perception measurement result, or the first device does not send feedback information on the feedback resource, so as to implicitly indicate the validity of the perception measurement result to the second device through this behavior.
[0082] The above-mentioned second device can be a terminal, a wireless access network device or a perception network function, such as a target signal sending device. In addition, the first device and the second device can be one of which is a wireless access network device and the other is a terminal, or the first device and the second device can be both wireless access network devices, or both are terminals, or the first device can be a terminal or a wireless access network device, and the second device can be a perception network function. For example: the first device sends and receives the target signal to perform perception measurement, and indicates the validity of the perception measurement result to the second device, and the second device can be a perception network function; or the first device receives the target signal to perform perception measurement, and indicates the validity of the perception measurement result to the second device, and the second device can be a perception network function or a target signal sending device.
[0083] In the embodiments of the present application, the above steps can be used to determine the validity of the perception measurement result based on the perception-related indicator associated with the target signal, and indicate the validity of the perception measurement result to the second device, thereby improving the feedback performance of the perception measurement result. In addition, in some embodiments, when the perception measurement result is indicated as invalid, the perception measurement result is not sent, thereby saving resource overhead.
[0084] As an optional implementation manner, the first device determines the validity of the perception measurement result based on the perception-related indicator associated with the target signal, including:
[0085] The first device determines validity of the perception measurement result based on first information, where the first information includes the perception-related indicator and at least one of the following:
[0086] Communication-related indicators associated with the target signal;
[0087] the perceptual measurement results;
[0088] a demodulation result of the target signal;
[0089] The time when the perception measurement result is obtained.
[0090] The communication-related indicators may include at least one of the following:
[0091] 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).
[0092] The demodulation result of the target signal may be a decoding success or a decoding failure of the target signal.
[0093] The acquisition time of the above-mentioned perception measurement result refers to the time when the first device obtains the above-mentioned perception measurement result.
[0094] In one of the above optional embodiments, in addition to perception-related indicators, the validity of the perception measurement result can be determined based on the communication-related indicators associated with the above-mentioned target signal, the perception measurement result, the demodulation result of the target signal or the acquisition time of the perception measurement result, so that the validity of the determined perception measurement result is more accurate.
[0095] In some embodiments, the perception measurement result may be determined to be invalid if at least one of the following conditions is met; otherwise, it may be determined to be valid:
[0096] The perception-related indicators do not meet the perception indicator conditions;
[0097] The communication-related indicator associated with the target signal does not meet the communication indicator condition;
[0098] The perception measurement result does not meet the perception measurement result requirement;
[0099] The first device fails to correctly demodulate the target signal;
[0100] The time for obtaining the perception measurement result does not meet the feedback time requirement.
[0101] At least one of the above-mentioned perception indicator conditions, communication indicator conditions, perception measurement result requirements, or feedback time requirements may be a protocol agreement or a network-side configuration, or may be set by the above-mentioned first device itself. For example, the above-mentioned perception-related indicator failing to meet the perception indicator condition may mean that the perception-related indicator fails to meet the threshold requirement, and the above-mentioned communication-related indicator failing to meet the communication indicator condition may mean that the communication-related indicator fails to meet the threshold requirement. The above-mentioned perception measurement result failing to meet the perception measurement result requirement may mean that the reliability, accuracy, perception precision, or value of the perception measurement quantity of the perception measurement result fails to meet the threshold requirement, such as whether the calculated Doppler value or target speed meets a preset range, or whether the calculated position coordinates meet a preset range. The preset range is associated with the perception requirement or perception prior information. For example, if the corresponding service in the perception requirement is target detection in a highway scene, the target speed should not exceed 150 km / h, but the measured target speed exceeds this range, the measurement result is considered invalid. Alternatively, if the location area range of the perception target is known based on the perception prior information, and the measured target position exceeds this area, the measurement result is considered invalid.
[0102] The above-mentioned first device fails to correctly demodulate the target signal, which can be based on perception of communication data, using a method of first demodulating and then estimating the perception parameters. If the communication demodulation is wrong, the perception measurement result is affected and becomes unreliable, so that the perception measurement result can be determined to be invalid.
[0103] The acquisition time of the above-mentioned perception measurement result failing to meet the feedback time requirement may be that the first device fails to obtain the perception measurement result within the valid time, that is, the perception measurement result processing times out, and thus it can be determined that the perception measurement result is invalid.
[0104] In some implementations, the perception measurement result may be determined to be valid when at least one of the following conditions is met:
[0105] The perception-related indicators meet the perception indicator conditions;
[0106] The communication-related indicator associated with the target signal meets the communication indicator condition;
[0107] The perception measurement result meets the perception measurement result requirement;
[0108] The first device correctly demodulates the target signal;
[0109] The time for obtaining the perception measurement results meets the feedback time requirement.
[0110] In some embodiments, the aforementioned perception-related indicators include perception indicators related to at least one of the following:
[0111] Received power, interference power, and noise power.
[0112] In which, the above-mentioned receiving power can be the receiving power of at least one signal path of the above-mentioned target signal, the above-mentioned interference power and noise power can be the interference power and noise power between the signal paths in the above-mentioned target signal, or the above-mentioned interference power and noise power can be the interference power and noise power generated by the above-mentioned other signals to the target signal.
[0113] As an optional implementation manner, the perception-related indicator includes at least one of the following:
[0114] Perception indicators related to received power;
[0115] Perceptual metrics related to interference or noise power;
[0116] A perceptual metric related to received power, and also to interference or noise power.
[0117] The above-mentioned received power-related perception indicators may include at least one of the following:
[0118] A perception indicator related to the received power of a target signal, and a perception indicator related to the received power of a signal path of the target signal associated with the perception target. For example, the perception indicator related to received power may include a first indicator, the first indicator being used to indicate the received power of the signal path of the target signal associated with the perception target.
[0119] 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.
[0120] In one of the aforementioned optional embodiments, since the perception-related indicators include a perception indicator related to received power, the validity of the perception measurement result can be determined based on received power, thereby making the validity of the perception measurement result more reliable. Furthermore, the validity of the perception measurement result can also be determined 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 the validity of the perception measurement result. Therefore, using this first indicator can make the validity of the perception measurement result more reliable.
[0121] In some embodiments, the first indicator may be a linear average (in W) of the received power of the signal path associated with the perceived target in the channel response obtained by measuring the target signal on the resource unit carrying the target signal, where the resource unit is a time domain or frequency domain resource unit. In this way, the received power may be made more accurate and reliable by the linear average. It should be noted that the embodiments of the present application do not limit the received power to a linear average. For example, in some embodiments, the median received power, the minimum received power, or the maximum received power may also be taken.
[0122] 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.
[0123] In the above optional implementation, since the perception-related indicators include perception indicators related to interference or noise power, interference or noise can be taken into account when determining the effectiveness of the perception measurement, so that the effectiveness of the perception measurement result is more reliable.
[0124] Optionally, the perception indicator related to the interference or noise power includes at least one of the following:
[0125] a second indicator, where the second indicator is the sum of the linear average of the powers of signal paths other than the signal path associated with the perception target in the channel response of the target signal on the target resource and the linear average of the interference or noise power from signals other than the target 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 indicator RSSI of the first device on the first resource;
[0126] a third indicator, where the third indicator is a linear average of interference or noise power from signals other than the target signal on the second resource, or the third indicator is equal to a difference between a total received power and a received power of the target signal, where the total received power is the total received power of the first device on the target resource, or the total received power is the power corresponding to the RSSI of the first device on the first resource;

[0129] The above-mentioned other signal paths may be all or part of the signal paths in the target signal except the signal path associated with the above-mentioned perception target.
[0130] The aforementioned other signals other than the target signal may refer to all or part of the signals other than the target signal detected by the first device on the first resource.
[0131] 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:

[0133] 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:
[0134] a target resource, and at least one resource other than the target resource.
[0135] 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.
[0136] The above-mentioned interference or noise power includes the sum of interference power and noise power, interference power or noise power.
[0137] 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.
[0138] 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.
[0139] The above-mentioned received power of the target signal refers to the RSRP of the target signal.
[0140] 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.
[0141] The third indicator equals the difference between the total received power and the received power of the target signal, which can be expressed as third indicator = total received power - target signal received power.
[0142] The fourth indicator equal to the difference between the received power of the target signal and the first indicator can be expressed as fourth indicator=received power of the target signal-first indicator.
[0143] In the above embodiment, the second indicator can be used to consider interference or noise from signal paths other than the signal path associated with the perception target and signals other than the target signal when determining the validity of the perception measurement result, thereby making the validity of the perception measurement result more reliable.
[0144] In the above embodiment, the third indicator can be used to consider interference or noise of other signals other than the target signal when determining the validity of the perception measurement result, which can make the validity of the perception measurement result more reliable.
[0145] 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 perception target when determining the validity of the perception measurement result, which can make the validity of the perception measurement result more reliable.
[0146] 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.
[0147] In one of the above optional embodiments, 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 the effectiveness of the perception measurement, so that the effectiveness of the perception measurement result is more reliable.
[0148] 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:
[0149] a fifth index, the fifth index being equal to a quotient obtained by dividing the first index by the second index;
[0150] a sixth index, the sixth index being equal to a quotient obtained by dividing the first index by the third index;
[0151] a seventh index, the seventh index being equal to a quotient obtained by dividing the first index by the fourth index;
[0152] an eighth indicator, the eighth indicator being equal to the product of a quotient obtained by dividing the first indicator by the total received power and a target coefficient;
[0153] The first indicator is used to indicate the received power of the signal path of the target signal associated with the perception target.
[0154] 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.
[0155] 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.
[0156] In this implementation, through the fifth indicator, the sixth indicator, the seventh indicator or the eighth indicator, it is possible to take the received power and the interference or noise into consideration when determining the effectiveness of the perception measurement, so that the effectiveness of the perception measurement result is more reliable.
[0157] 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:
[0158] Indicators related to perceived SINR, indicators related to perceived SNR, indicators related to perceived signal-to-interference ratio (SIR), and indicators related to perceived RSRQ.
[0159] As an optional implementation manner, the signal path associated with the perception target satisfies at least one of the following:
[0160] The parameter meets the first preset threshold, or the parameter is within the first preset range;
[0161] The parameters meet the preset modulation rules;
[0162] 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;
[0163] 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.
[0164] The above parameters may include at least one of the following:
[0165] Amplitude, power, intensity, energy, phase, Doppler, delay, angle;
[0166] The above parameter difference may include at least one of the following:
[0167] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, delay difference, and angle difference.
[0168] 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.
[0169] 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).
[0170] 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.
[0171] 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.
[0172] 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.
[0173] 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.
[0174] 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.
[0175] 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 into a first dimension and determines the signal path associated with the perception target in the first 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.
[0176] The first dimension includes one of the following:
[0177] Delay dimension;
[0178] Doplevi;
[0179] Azimuth dimension;
[0180] Pitch angle dimension;
[0181] A dimension that combines at least two of the following: delay, Doppler, azimuth, and elevation dimensions. For example, delay-Doppler, delay-Doppler-angle, etc.
[0182] 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 (first 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 (first 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 (first 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.
[0183] 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:
[0184] Determine the signal path set. The signal paths in the signal path set include those whose amplitude, power, intensity, or energy exceeds a certain threshold among all paths after the channel response is transformed into the first 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. 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.
[0185] A signal path that satisfies a first condition is selected from the signal path set or from all signal paths of the target signal as the signal path associated with the sensing target. The first condition includes at least one of the following:
[0186] 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;
[0187] The Doppler of the signal path exceeds the preset threshold or is within the preset range;
[0188] The signal path delay exceeds the preset threshold or is within the preset range;
[0189] The angle of the signal path exceeds the preset threshold or is within the preset range;
[0190] 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).
[0191] 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;
[0192] 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;
[0193] 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;
[0194] 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.
[0195] The above-mentioned first 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;
[0196] 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.
[0197] The priori perception information or perception requirements include the following information:
[0198] 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;
[0199] 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;
[0200] 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.
[0201] 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.
[0202] For example, in Figure 4, signal paths 0, 1, 2, and 3 are paths in the signal path set, among which signal paths 2 and 3 are perception paths that meet the first condition (for example, their delays meet the preset threshold), and paths 0 and 1 are paths associated with other scatterers.
[0203] In Figure 4, the channel response is a schematic diagram of multiple signal paths in the first dimension (delay dimension, Doppler dimension, azimuth dimension, or elevation angle dimension), where the horizontal axis is the first dimension and the vertical axis is the normalized amplitude, power, intensity or energy.
[0204] 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.
[0205] Calculation method 2 of the first indicator:
[0206] 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 first dimension and The difference between is used as the first indicator, where N1 represents the number of signal paths associated with the perception target. is the average power of multiple signal paths outside the signal path set in the first dimension.
[0207] The received power of the target signal is calculated as follows:
[0208] The received power of the target signal can be obtained by the receiving device, transforming the channel response (Channel Response) H(k) into the first dimension, determining a signal path set in the first dimension, and then calculating the power sum of all signal paths in the signal path set.
[0209] Method 2 for calculating the received power of the target signal:
[0210] 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 first dimension and , where N2 represents the number of signal paths in the signal path set.
[0211] The total received power is calculated as follows:
[0212] Total received power
[0213] 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.
[0214] The calculation method of the second indicator is:
[0215] 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:
[0216] The first filtering process is used to eliminate noise and interference in the first 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.
[0217] Calculation method of the third indicator:
[0218] 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:
[0219] The second filtering process can be a noise interference suppression process in the first 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.
[0220] Calculation method 2 for the third indicator:
[0221] According to the average power of multiple signal paths outside the signal path set in the first dimension Calculate the third index P σ2 ,Right now Where N represents the number of sampling points in the first dimension.
[0222] 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:
[0223] Method 1: Calculate the perception-related indicators (also called target indicators) of 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; when calculating the second indicator corresponding to a certain perception target (such as perception target A), there are two methods: namely: 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 = RSRP of target signal - the first indicator of perception target A; or, the fourth indicator of perception target A = RSRP of 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)
[0224] 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.
[0225] As an optional implementation manner, the first device indicating the validity of the perception measurement result to the second device includes:
[0226] The first device sends feedback information to the second device, where the feedback information is used to indicate the validity of the perception measurement result.
[0227] The feedback information may be used to indicate the validity of the perception measurement result, including the following:
[0228] The perception measurement result is invalid, the perception measurement result is valid, and the validity level of the perception measurement result.
[0229] The invalidity of the aforementioned perception measurement results may be that all or part of the perception measurement results are invalid.
[0230] The above-mentioned perception measurement results being valid may be that all or part of the perception measurement results are valid.
[0231] The validity level of the above-mentioned perception measurement results may refer to dividing the validity of the perception measurement results into multiple levels, or may refer to dividing the perception measurement results into different validity levels according to different indicators, such as respectively feeding back the corresponding validity for different indicators, that is, the perception-related indicators corresponding to the perception measurement results (for example, the received power of the signal path associated with the perception target, the perception SINR, etc.) are different, or there are multiple thresholds for judging the validity of the measurement results. Assuming there are two thresholds, this can be divided into three levels: invalid, valid according to the first threshold but invalid according to the second threshold, and valid according to the second threshold (assuming that the second threshold requirement is higher). Among them, the validity level can also be referred to as the validity state.
[0232] The effectiveness of the feedback can be made more precise by using the effectiveness level of the above-mentioned perception measurement results.
[0233] In the above optional implementation manner, by sending feedback information to indicate the validity of the perception measurement result, the validity of the perception measurement result can be indicated to the second device more intuitively.
[0234] Optionally, when the feedback information indicates that the perception measurement result is invalid, the feedback information is further used to indicate at least one of the following:
[0235] The invalid reason of the perception measurement result, the recommended configuration of the target signal, and the perception-related indicators.
[0236] The invalid reason for the above-mentioned perception measurement result may include at least one of the following:
[0237] The perception-related indicators do not meet the perception indicator conditions;
[0238] The communication-related indicator associated with the target signal does not meet the communication indicator condition;
[0239] The perception measurement result does not meet the perception measurement result requirement;
[0240] The first device fails to correctly demodulate the target signal;
[0241] The time for obtaining the perception measurement result does not meet the feedback time requirement.
[0242] Among them, the above-mentioned perception indicator conditions, communication indicator conditions, perception measurement result requirements and feedback time requirements refer to the corresponding description of the above-mentioned implementation methods and are not repeated here.
[0243] The invalid reasons of the above-mentioned perception measurement results can enable the second device to adjust the configuration of the target signal based on these reasons, thereby facilitating the improvement of the validity of the perception measurement results.
[0244] The recommended configuration of the target signal is a signal configuration recommended by the first device based on the invalidity of the perception measurement result. The signal configuration is beneficial to improving the validity of the perception measurement result.
[0245] The above-mentioned perception-related indicators are used to indicate that the above-mentioned perception measurement results are invalid, which is determined based on the indicators. In this way, the second device adjusts the configuration of the target signal based on these indicators, which is conducive to improving the validity of the perception measurement results.
[0246] Optionally, when the feedback information indicates that the perception measurement result is valid, the feedback information is further used to indicate the perception measurement result.
[0247] The feedback information is also used to indicate that the perception measurement result is carried in the feedback information, so that the perception measurement result can be directly fed back, thereby improving feedback performance.
[0248] Optionally, the feedback information is further used to indicate at least one of the following:
[0249] an identification of the target signal associated with the perception measurement result;
[0250] Perception measurement identification information;
[0251] Data volume information of the feedback information;
[0252] the number of valid sensory measurement results indicated by the feedback information;
[0253] The feedback information indicates the number of invalid perception measurement results.
[0254] Among them, the identifier of the target signal associated with the perception measurement result is used to indicate the specific target signal for which the validity indication of the perception measurement result is directed. For example, in a scenario where multiple target signals are sent, the above identifier can indicate the target signal for which the validity of the above perception measurement result is directed, thereby improving the accuracy of the feedback.
[0255] The above-mentioned perception measurement identification information can be the ID of the perception measurement configuration. The identification information is used to indicate the perception measurement for which the validity indication of the perception measurement result is directed. For example, if there are multiple perception measurements, the identification information can indicate the specific number of multiple perception measurements for which the validity of the above-mentioned perception measurement result is directed, thereby improving the accuracy of the feedback.
[0256] The data volume information of the feedback information may be the total number of bits of the feedback information. The data volume information may enable the second device to more simply and reliably parse the content indicated by the feedback information, thereby improving feedback performance.
[0257] The number of valid or invalid perception measurement results indicated by the above feedback information can realize feedback of multiple perception measurement results in one feedback information. Through this number, the second device can more simply and reliably parse the valid or invalid perception measurement results indicated by the feedback information to improve feedback performance.
[0258] Optionally, the target signal is also used for communication, and the feedback information is also used to indicate correctness of received communication data.
[0259] The target signal is also used for communication, which means that the target signal is used for sensing measurement and also for communication.

[0266] The overhead of feedback information can be saved by joint coding indication.
[0267] The above feedback information carries the indication of the validity of the perception measurement result and the indication of the correctness of the communication data reception respectively, which means that the validity of the perception measurement result and the correctness of the communication data reception are indicated by different bits in the feedback information.

[0427] Example 2:
[0428] This embodiment mainly describes the reporting format of feedback information when a single perception measurement result is fed back.
[0429] In this embodiment, a validity indication of a single perception measurement result is fed back each time, wherein each perception measurement result (or each perception measurement result validity indication) is associated with one or more perception measurements, and the one perception measurement may be a measurement based on one or more target signals.

[0433] Feedback is multi-bit (if divided into m states, ceil(log2(m)) bits are required to represent it). For example, the validity of the measurement result is divided into different levels, that is, the perception-related indicators corresponding to the measurement result (such as the received power of the signal path associated with the perception target, the perception SINR, etc.) are different, or there are multiple thresholds for judging the validity of the measurement result (assuming there are two thresholds). Then, the three states can be divided into invalid, valid according to the first threshold but invalid according to the second threshold, and valid according to the second threshold (assuming the second threshold requirement is higher).
[0434] Format 2, feedback of valid perception measurement results or invalid perception measurement results or DTX: Feedback of 1 bit or multiple bits, as described in the above format 1 or DTX (i.e., no signal is sent on the designated feedback channel resource. For example, when the receiving end does not detect the target signal or at least one of the detected target signal SNR, RSRP, RSSI, and signal-to-interference ratio does not meet the threshold requirement, DTX is fed back. In this case, DTX can be used to indirectly feedback the reason for the invalid perception measurement result).

[0436] Format 4: Feedback of valid perception measurement result + perception measurement result or feedback of invalid perception measurement result + invalid reason: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the reason for the invalidity of the perception measurement result is fed back.
[0437] Format 5: Feedback of valid perception measurement result + perception measurement result or feedback of invalid perception measurement result + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the recommended target signal parameter configuration is fed back.
[0438] Format 6: Feedback of valid perception measurement result + perception measurement result or feedback of invalid perception measurement result + invalid reason + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the invalid reason for the perception measurement result and the recommended target signal parameter configuration are fed back.
[0439] Format 7: Feedback that the perception measurement result is valid or feedback that the perception measurement result is invalid + reason for invalidity: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback the reason for the invalidity of the perception measurement result.
[0440] Format 8, feedback of valid perception measurement result or invalid perception measurement result + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of recommended target signal parameter configuration is provided.
[0441] Format 9, feedback of valid perception measurement result or invalid perception measurement result + invalid reason + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback is also provided for the invalid reason of the perception measurement result and the recommended target signal parameter configuration.
[0442] Format 10: Only when the perception measurement result is invalid, the invalidity of the perception measurement result or the invalidity reason or the recommended target signal parameter configuration is fed back; when the perception measurement result is valid, no feedback is given.
[0443] Format 11: Only when the perception measurement result is valid, the perception measurement result or the perception measurement result is fed back; when the measurement result is invalid, no feedback is given.
[0444] Example 3:
[0445] This embodiment mainly describes the reporting format of feedback information when multiple perception measurement results are jointly fed back.
[0446] In this embodiment, validity indications of n (n>1) perception measurement results are fed back each time, where each perception measurement result (or each perception measurement result validity indication) is associated with one or more perception measurements, and the one perception measurement can be a measurement based on one or more target signals.
[0447] The feedback information format may include:
[0448] Format 1: Feedback of valid or invalid sensing measurement results, which may include the following:
[0449] Mode a: Feedback n bits, corresponding to the validity of n perception measurement results, for example, where "0" in each bit indicates that the perception measurement result is invalid, and "1" indicates that the perception measurement result is valid;
[0450] Mode b feedback is 1 bit, for example: the logical AND of the validity of n perception measurement results (n bits), "0" indicates that at least one perception measurement result is invalid, "1" indicates that all n perception measurement results are valid, or when more than x (x<=n, when x=n, the effect is equivalent to logical AND) of the n perception measurement results are valid, feedback is "1", otherwise feedback is "0";
[0451] Method c: Feedback n*m bits corresponds to the validity of n perception measurement results. The validity of each perception measurement result is represented by m bits (corresponding to x validity-related states, m=ceil(log2(x)) bits are required to represent it). For example, the validity of the measurement results is divided into different levels, that is, the target indicators corresponding to the measurement results (such as the received power of the perceived target association path, the perceived SINR, etc.) are different, or there are multiple thresholds for judging the validity of the measurement results (assuming there are two thresholds). Then, the validity can be divided into three states: invalid, valid according to the first threshold but invalid according to the second threshold, and valid according to the second threshold (assuming the second threshold requirement is higher).
[0452] Format 2: Feedback of valid perception measurement result + perception measurement result or feedback of invalid perception measurement result: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid.
[0453] Specifically, the format may include the following:
[0454] Method a: Feedback the perception measurement result each time the effectiveness indication is fed back, for example, as shown in Table 3 below:
[0455] Table 3:
[0456] Mode b: first feed back the n-bit validity indication, and then feed back the perception measurement result, as shown in Table 4 below:
[0457] Table 4:
[0458] Mode c, for the case where a 1-bit validity indication is fed back in mode b in format 1, the format may be feedback of a 1-bit valid indication + a perception measurement result or feedback of a 1-bit invalid indication, where the valid case is that x (x<=n) of the n perception measurement results are valid. In this case, x perception measurement results are fed back, as shown in the following Table 5:
[0459] Table 5:
[0460] It should be noted that, in the embodiment of the present application, the format of the feedback information is only described in the form of a table, but the feedback information is not limited to being fed back in the form of a table.
[0461] It should be noted that when feeding back perception measurement results, the number of bits for each perception measurement result is fixed. This can be agreed upon by the sender and receiver (as specified in the protocol), or the sender of the feedback information can indicate the number of bits of the perception measurement result / the number of bits of the feedback information. In particular, for method b) of format 2, the n-bit validity indicator precedes the perception result. The validity indicator and the perception result can be encoded separately. The receiver first detects the first n-bit validity indicator and then knows the number of perception results. In this case, the receiver only needs to know the number of bits of each perception measurement result to correctly decode it.
[0462] The following is similar to the feedback on the reasons for invalid perception measurement results and recommended target signal parameter configurations.
[0463] Format 3: Feedback of valid perception measurement result + perception measurement result or feedback of invalid perception measurement result + invalid reason: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid and feedback of the perception measurement result is fed back; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid and feedback of the invalid reason is fed back. Specifically, the format includes the following:
[0464] Method a: Feedback the perception measurement result or invalid reason each time the validity indication is fed back, for example, as shown in Table 6 below:
[0465] Table 6:
[0466] Mode b: First, feedback the n-bit validity indication, and then feedback the perception measurement results and invalid reasons in sequence, as shown in Table 7 below:
[0467] Table 7:
[0468] Mode c: The perception measurement results when the perception measurement results are valid and the invalid reasons when the perception measurement results are invalid may be fed back separately. Assuming that there are x valid perception measurement results and y invalid perception measurement results, x perception measurement results and p (p<=y) invalid reasons are fed back, as shown in Table 8 or Table 9 below:
[0469] Table 8:
[0470] Table 9:
[0471] It should be noted that information with high importance or high latency requirements can be placed first. For example, if the perception measurement results are more important, they can be placed first. Perception measurement results can also be encoded independently. (The same applies to the following regarding the order of perception measurement results, invalidation reasons, and recommended target signal parameter configurations.)
[0472] Mode d. In particular, for the case where a 1-bit validity indication is fed back in mode b in format 1, the format may be feedback of a 1-bit valid indication + a perception measurement result or feedback of a 1-bit invalid indication + an invalid reason, where the valid case is that x (x<=n) of the n perception measurement results are valid, and the invalid case is that y (y<=n) of the n perception measurement results are invalid. In this case, p (p<=y) invalid reasons are fed back, for example, as shown in Table 10 or Table 11 below:
[0473] Table 10:
[0474] Table 11:
[0475] For mode c in format 3 and mode d in format 3, the number of invalid reasons fed back may be less than the number of invalid perception measurement results, because the same invalid reason may be fed back only once or only the invalid reasons of some invalid perception measurement results may be selected for feedback. Compared with the method of sequentially feeding back perception measurement results and invalid reasons, feedback overhead can be saved. However, since the number of feedback information bits is uncertain at this time, it is necessary to indicate the total number of feedback bits or the number of invalid reasons fed back, otherwise the receiving end may not be able to correctly decode the feedback information.
[0476] Format 4: Feedback of valid perception measurement result + perception measurement result or feedback of invalid perception measurement result + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the recommended target signal parameter configuration is fed back. Specifically, the format may include the following:
[0477] Method a: Feedback the perception measurement results or recommended parameter configuration each time the effectiveness indication is fed back, for example, as shown in Table 12 below:
[0478] Table 12:
[0479] Mode b: First, feedback the n-bit validity indication, and then feedback the perception measurement results and recommended parameter configuration in sequence, as shown in Table 13 below:
[0480] Table 13:
[0481] Mode c: The perception measurement results when the perception measurement results are valid and the invalid reasons when the perception measurement results are invalid may also be fed back separately. Assuming that there are x valid perception measurement results and y invalid perception measurement results, x perception measurement results and q (q<=y) recommended target signal parameter configurations are fed back, for example, as shown in Table 14 or Table 15 below:
[0482] Table 14:
[0483] Table 15:
[0484] Mode d, in particular, for the case where a 1-bit validity indication is fed back in mode b in format 1, the format may be feedback of a 1-bit valid indication + perception measurement result or feedback of a 1-bit invalid indication + recommended parameter configuration, where the valid case is x (x<=n) of the n perception measurement results being valid, and the invalid case is y (y<=n) of the n perception measurement results being invalid. In this case, p (p<=y) invalid reasons are fed back, as shown in Table 16 or Table 17 below:
[0485] Table 16:
[0486] Table 17:
[0487] For method c and method d in format 4, the number of recommended parameter configurations fed back can be less than the number of invalid perceptual measurement results. This is because the same recommended parameter configuration can be fed back only once, or only some of the recommended parameter configurations can be selected for feedback (for example, if recommended parameter configuration 1 is for 100MHz bandwidth and recommended parameter configuration 2 is for 120MHz bandwidth, only recommended parameter configuration 2 is fed back). This reduces feedback overhead compared to sequentially feeding back perceptual measurement results and recommended parameter configurations. However, because the number of feedback information bits is uncertain, the total number of bits fed back or the number of recommended target signal parameter configurations fed back must be indicated. Otherwise, the receiving end may not be able to correctly decode the feedback information. The same applies to the feedback of recommended target signal parameter configurations below.
[0488] Format 5: Feedback of valid perception measurement result + perception measurement result or feedback of invalid perception measurement result + invalid reason + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the reason for the invalid perception measurement result and the recommended target signal parameter configuration are fed back. Specifically, the format may include the following:
[0489] Method a: Feedback the perception measurement result or invalid reason + recommended parameter configuration each time the validity indication is fed back, such as shown in Figure 18 or Table 19 below:
[0490] Table 18:
[0491] Table 19:
[0492] Mode b: Feedback an n-bit validity indication, and then feedback the sensing measurement result + invalid reason + recommended parameter configuration in sequence, for example, as shown in Table 20 or Table 21 below:
[0493] Table 20:
[0494] Table 21:
[0495] Mode c: The perception measurement results when the perception measurement results are valid and the invalid reasons and recommended parameter configurations when the perception measurement results are invalid may also be fed back separately. Assuming that there are x (x<=n) valid perception measurement results and y (y<=n) invalid perception measurement results, then x perception measurement results and p (p<=y) invalid reasons and q (q<=y) recommended parameter configurations are fed back, for example, as shown in Table 22, Table 23, Table 24 or Table 25 below:
[0496] Table 22:
[0497] Table 23:
[0498] Table 24:
[0499] Table 25:
[0500] Method d. In particular, for the case where a 1-bit validity indication is fed back in method b in format 1, the format can be feedback of a 1-bit valid or invalid indication ("0" or "1") + perception measurement result + invalid reason + recommended parameter configuration. The specific format is the same as the 4 formats in 5) c) above, the difference being that the previous n-bit validity indication becomes a 1-bit validity indication.
[0501] In addition, in the feedback format, the reasons and recommended parameter configurations when the perception measurement results are invalid may be placed first, followed by the perception measurement results. The specific format is the same as above and will not be listed again.
[0502] Format 6: Feedback of valid perception measurement result or invalid perception measurement result + invalid reason: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of the invalid reason is included. Specifically, the format may include the following:
[0503] Method a: Each time a validity indication is fed back, the invalid reason is fed back, as shown in Table 26 below:
[0504] Table 26:
[0505] Mode b: First, n bits of validity indication are fed back, and then invalid reasons are fed back in order. Assuming that there are x valid perception measurement results and y invalid perception measurement results, p (p<=y) invalid reasons are fed back, as shown in Table 27 below:
[0506] Table 27:
[0507] Mode c, in particular, for the case where a 1-bit validity indication is fed back in mode b in format 1, the format may be a 1-bit valid indication or a 1-bit invalid indication + invalid reason. The valid case is that x (x<=n) of the n perception measurement results are valid, and the invalid case is that y (y<=n) of the n perception measurement results are invalid. In this case, p (p<=y) invalid reasons are fed back, for example, as shown in Table 28 or 29 below:
[0508] Table 28:
[0509] Table 29:
[0510] Format 7: Feedback of valid perception measurement results or invalid perception measurement results + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback is provided with recommended target signal parameter configuration. Specifically, the format may include the following:
[0511] Method a: Feedback suggestion parameter configuration each time the effectiveness indication is fed back, for example, as shown in Table 30 below:
[0512] Table 30:
[0513] Mode b: First, n bits of validity indication are fed back, and then invalid reasons are fed back in order. Assuming that there are x valid perception measurement results and y invalid perception measurement results, q (q<=y) invalid reasons are fed back, as shown in Table 31 below:
[0514] Table 31:
[0515] Mode c, in particular, for the case where a 1-bit validity indication is fed back in mode b in format 1, the format may be a 1-bit valid indication or a 1-bit invalid indication + invalid reason. The valid case is that x (x<=n) of the n perception measurement results are valid, and the invalid case is that y (y<=n) of the n perception measurement results are invalid. In this case, q (q<=y) recommended parameter configurations are fed back, as shown in Table 32 or Table 33 below:
[0516] Table 32:
[0517] Table 33:
[0518] Format 8: Feedback of valid perception measurement results or invalid perception measurement results + invalid reason + recommended target signal parameter configuration: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback is also provided with the invalid reason and recommended target signal parameter configuration. Specifically, the format may include the following:
[0519] Method a: Feedback the perception measurement result or invalid reason + recommended parameter configuration each time the validity indication is fed back, for example, as shown in Table 34 or Table 35 below:
[0520] Table 34:
[0521] Table 35:
[0522] Mode b: First, feedback is given of an n-bit validity indication, and then feedback is given of an invalid reason + a recommended parameter configuration. Assuming that there are x valid perception measurement results and y invalid perception measurement results, feedback is given of x perception measurement results, p (p <= y) invalid reasons, and q (q <= y) recommended parameter configurations, as shown in Table 36 or Table 37 below:
[0523] Table 36:
[0524] Table 37:
[0525] Method c: When the perception measurement result is invalid, the invalid reason and the recommended parameter configuration can also be fed back separately, for example, as shown in Table 38 or Table 39 below:
[0526] Table 38:
[0527] Table 39:
[0528] Mode d. In particular, for the case where a 1-bit validity indication is fed back in mode b in format 1, the format may be a 1-bit valid indication or a 1-bit invalid indication + invalid reason + recommended parameter configuration. The invalid specific format is the same as the 4 formats in 8) b) and c), except that the previous n-bit validity indication becomes a 1-bit invalid indication (1 bit "0"). The indication when valid is shown in Table 40 below:
[0529] Table 40:
[0530] Format 9. As described in the method provided in an embodiment of the present application, only when the first perception measurement result is valid, the feedback information includes a perception measurement result valid indication or a perception measurement result of the first perception measurement result; when the first perception measurement result is invalid, the feedback information related to the first perception measurement result is not included, and the first perception measurement result is 1 of n perception measurement results.
[0531] Since the number of bits of the feedback information is uncertain at this time, it is necessary to indicate the total number of feedback bits or the number of valid measurement results, otherwise the receiving end may not be able to correctly decode the feedback information.
[0532] Format 10. As described in the method provided in an embodiment of the present application, only when the first perception measurement result is invalid, the feedback information includes an invalid perception measurement result indication or invalid reason or a recommended target signal parameter configuration of the first perception measurement result; when the first perception measurement result is valid, the feedback information related to the first perception measurement result is not included, and the first perception measurement result is 1 of n perception measurement results.
[0533] Since the number of bits of the feedback information is uncertain at this time, it is necessary to indicate the total number of feedback bits or the number of invalid measurement results, otherwise the receiving end may not be able to correctly decode the feedback information.
[0534] Example 4:
[0535] This embodiment mainly describes the reporting format of feedback information when a single perception measurement and communication are jointly fed back.
[0536] In this embodiment, a single perception measurement result validity indication and a single communication data reception correctness indication are fed back each time, as shown in Figure 6. Each perception measurement result (or each perception measurement result validity indication) is associated with one or more perception measurements, and the perception measurement may be based on one or more target signals.
[0537] The feedback information format may include:
[0538] Format 1: Feedback of valid or invalid sensing measurement results + correct or incorrect communication data reception, including the following methods:
[0539] Mode a: Feedback 2 bits:
[0540] Each bit indicates the validity of the perception measurement result and the correctness of the communication data reception, respectively. Joint coding or independent coding can be used (the independent coding code rates can be different to meet different priority or importance requirements): one bit indicates the validity of the perception measurement result: for example, "0" indicates that the perception measurement result is invalid, and "1" indicates that the perception measurement result is valid; the other bit indicates the correctness of the communication data reception, that is, ACK / NACK: for example, "0" indicates that the communication data reception is incorrect (Negative Acknowledgement, NACK), and "1" indicates that the communication data is correctly received (Acknowledgement, ACK);
[0541] Alternatively, 2 bits jointly indicate the validity of the perception measurement result and the correctness of the communication data reception, using joint coding, that is, a total of 4 states. In particular, for example, the situation where the communication data is received incorrectly but the perception measurement result is valid may not exist, then the 2-bit value corresponding to this state (communication data reception error and perception measurement result is valid) can be reserved (reserved), as shown in Table 2 above.
[0542] Mode b: Feedback 1 bit, for example, the logical AND result of the validity of the perception measurement result and the communication data reception correctness indication information: "0" indicates that the communication data is received incorrectly (NACK) or the perception measurement result is invalid, and "1" indicates that the communication data is received correctly (ACK) and the perception measurement result is valid.
[0543] Method c: In particular, if the method is based on communication data perception, that is, the target signal is a communication data signal, 1 bit or 2 bits can also be fed back. The method may include:
[0544] When communication data reception error occurs, 1 bit is used to indicate it, and “0” indicates communication data reception error (NACK) and the perception measurement result is invalid;
[0545] Alternatively, when the communication data is received correctly, 2 bits are used to indicate that the communication data is received correctly (ACK), where 1 bit is "1" indicating that the communication data is received correctly (ACK), and the other bit is used to indicate whether the perception measurement result is valid. The communication data reception correctness indication and the perception measurement result validity indication need to be independently encoded, and the communication data reception correctness indication comes first.
[0546] Mode d, feedback m+1 (m>1) bits, for example, the validity of the perception measurement result is divided into x different levels (corresponding to x states related to validity, m=ceil(log2(x)) bits are required to represent), that is, the target indicators corresponding to the measurement results (such as the received power of the perceived target association path, the perceived SINR, etc.) are different, or there are multiple thresholds for judging the validity of the measurement results (assuming there are two thresholds), then it can be divided into invalid, valid according to the first threshold but invalid according to the second threshold, and valid according to the second threshold (assuming that the second threshold requirement is higher). Similar to the case of 2-bit representation, m bits and 1 bit can be used to indicate the validity of the perception measurement result and the correctness of the communication data reception, respectively, or m+1 bits can be used to jointly indicate the validity of the perception measurement result and the correctness of the communication data reception.
[0547] Mode e, DTX. For example, if the first device fails to detect the target signal or at least one of the detected target signal's SNR, RSRP, RSSI, and signal-to-interference ratio does not meet a threshold, DTX feedback is provided. This means that no signal is transmitted on the designated feedback channel time-frequency resources. In this case, DTX can be used to indirectly feedback the reason for the invalid measurement result.
[0548] Specifically, when the validity of the perception measurement result and the correctness of the communication data reception are independently encoded, an indication state can be added separately using the DTX method (no signal is sent on the time-frequency domain feedback resources corresponding to the respective indications of the validity of the perception measurement result and the correctness of the communication data reception); when the validity of the perception measurement result and the correctness of the communication data reception are jointly encoded, an indication state can also be added as a whole using the DTX method (no signal is sent on the time-frequency domain feedback resources corresponding to the joint encoding information).
[0549] Format 2: Feedback of valid perception measurement result + perception measurement result + communication data reception correctness or feedback of invalid perception measurement result + communication data reception correctness: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback is given of the perception measurement result and communication data reception correctness; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback is given of communication data reception correctness. Specifically, the format may include the following:
[0550] Mode a: When feeding back the perception measurement result validity indication, the perception measurement result is fed back, and then the communication data reception correctness indication is fed back, for example, as shown in Table 41 or Table 42 below:
[0551] Table 41:
[0552] Table 42:
[0553] Mode b: You may also first feed back the perception measurement result validity indication and the communication data reception correctness indication, and then feed back the perception measurement result, as shown in Table 43 or Table 44 below:
[0554] Table 43:
[0555] Table 44:
[0556] Among them, the above feedback format can also be that the communication data reception correctness indication comes first, and the perception measurement result validity indication and perception measurement result come second, that is, high-priority information is placed in front. When the communication feedback is more important, communication is placed in front, otherwise perception is placed in front.
[0557] Format 3: Feedback of valid perception measurement result + perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + invalid reason + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback is given of the perception measurement result and communication data reception correctness indication; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback is given of the invalid reason for the perception measurement result, and communication data reception correctness indication. Specifically, the format may include the following:
[0558] Mode a: When feeding back the perception measurement result validity indication, the perception measurement result is fed back, and then the communication data reception correctness indication is fed back, for example, as shown in Table 45 or Table 46 below:
[0559] Table 45:
[0560] Table 46:
[0561] Method c: You can also first feed back the perception measurement result validity indication and the communication data reception correctness indication, and then feed back the perception measurement result, for example, as shown in Table 47 or Table 48 below:
[0562] Table 47:
[0563] Table 48:
[0564] In addition, the above feedback format can also be that the communication data reception correctness indication is in front, and the perception measurement result validity indication and the perception measurement result or invalid reason are in the back, that is, the high priority information is placed in front. When the communication feedback is more important, the communication is placed in front, otherwise the perception is placed in front.
[0565] Format 4: Feedback of valid perception measurement result + perception measurement result + communication data reception correctness indication, or feedback of invalid perception measurement result + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, as well as the communication data reception correctness indication, and feedback of the perception measurement result; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of the recommended target signal parameter configuration and the communication data reception correctness indication is given.
[0566] The specific format is format 3 above, where the invalid reason is replaced by the recommended target signal parameter configuration.
[0567] Format 5, feedback of valid perception measurement result + perception measurement result + communication data reception correctness indication, or feedback of invalid perception measurement result + invalid reason + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback is given of the perception measurement result and the communication data reception correctness indication; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback is given of the invalid reason for the perception measurement result, the recommended target signal parameter configuration, and the communication data reception correctness indication.
[0568] The specific format is the same as Format 3 above, where the invalid reason is replaced with invalid reason + recommended target signal parameter configuration.
[0569] Among them, in addition to the communication data reception correctness indication and the perception measurement result validity indication and the perception measurement result or invalid reason, the order of priority can be determined according to the feedback priority. The invalid reason and the recommended target signal parameter configuration can also be determined according to the importance. At this time, the two can be independently encoded.
[0570] Format 6, feedback of valid perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + invalid reason + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback of communication data reception correctness indication is given; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of the invalid reason for the perception measurement result and communication data reception correctness indication is given.
[0571] The specific format is the same as the above format 3, wherein the perception measurement result is no longer fed back when the perception measurement result is valid.
[0572] Format 7, feedback of valid perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback of communication data reception correctness indication is given; when the perception measurement result is invalid, feedback "0" indicates that the perception measurement result is invalid, and feedback of recommended target signal parameter configuration is given, and feedback of communication data reception correctness indication is given.
[0573] The specific format is the same as format 3 above, where the perception measurement result is no longer fed back when it is valid, and the invalid reason is replaced by the recommended target signal parameter configuration.
[0574] Format 8, feedback of valid perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + invalid reason + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback of communication data reception correctness indication; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of the invalid reason for the perception measurement result and recommended target signal parameter configuration, as well as feedback of communication data reception correctness indication.
[0575] The specific format is the same as the above format 5, wherein the perception measurement result is no longer fed back when the perception measurement result is valid.
[0576] Format 9: Only when the perception measurement result is valid, the perception measurement result validity or the perception measurement result + communication data reception correctness indication is fed back; when the measurement result is invalid, only the communication data reception correctness indication is fed back.
[0577] Only when the perception measurement result is invalid, the invalidity of the perception measurement result or the invalidity reason or the recommended target signal parameter configuration + communication data reception correctness indication is fed back; when the measurement result is valid, only the communication data reception correctness indication is fed back.
[0578] Embodiment 5:
[0579] This embodiment mainly describes the reporting format of feedback information when multiple perception measurements and communication are jointly fed back.
[0580] In this embodiment, m perception measurement result validity indications and n communication data reception correctness indications (m+n>2) are fed back each time, as shown in FIG7 , corresponding to the cases where m>1, n=1 and m=1, n>1, respectively. Each perception measurement result (or each perception measurement result validity indication) is associated with one or more perception measurements, and the one perception measurement may be a measurement based on one or more target signals.
[0581] Feedback information formats may include:
[0582] Format 1: Feedback of valid or invalid sensing measurement results + correct or incorrect communication data reception, including the following methods:
[0583] Mode a: Feedback m+n bits, for example:
[0584] The m bit and n bit indicate the validity of the perception measurement result and the correctness of the communication data reception, respectively, and can adopt joint coding or independent coding (the independent coding code rate can be different to meet different priority or importance requirements): the m bit indicates the validity of the perception measurement result: for example, for each bit in the m bits, "0" indicates that the perception measurement result is invalid, and "1" indicates that the perception measurement result is valid; the n bit indicates the correctness of the communication data reception, that is, ACK / NACK: for example, for each bit in the n bits, "0" indicates that the communication data is received incorrectly (NACK), and "1" indicates that the communication data is received correctly (ACK).
[0585] Alternatively, in particular, there are x (x <= m and x <= n) associated perception measurement result validity and communication data reception correctness indications (a total of 2*x bits) among the m perception measurement result validity and n communication data reception correctness indications, wherein each associated 2 bits jointly indicate the perception measurement result validity and the communication data reception correctness, and joint coding is adopted, that is, each 2 bits represents 4 states. In particular, for example, the case where the communication data is received incorrectly but the perception measurement result is valid may not exist, then the 2-bit value corresponding to the state (communication data reception error and perception measurement result valid) can be reserved, for example, as shown in Table 48 below:
[0586] Table 48
[0587] The remaining mx bits and nx bits indicate the validity of the perception measurement results and the correctness of the communication data reception, respectively, as shown in Table 49 below:
[0588] Table 49
[0589] It should be noted that the order of the joint coding indication information, the perception measurement result validity indication information, and the communication data reception correctness indication information is not restricted, for example, it can be determined according to the feedback priority, and the three can be independently encoded.
[0590] In particular, when the following conditions exist: x=m, x=n, x=m=n, there may be no bit that separately indicates the validity of the perception measurement result or the correctness of the communication data reception, as shown in Table 50, Table 51, or Table 52 below:
[0591] Table 50, corresponding to x=m <n:
[0592] Table 51, corresponding to x = n < m:
[0593] Table 52, corresponding to x = m = n:
[0594] Method b: Feedback 2 bits. For example, one bit is the logical AND result of the m bits indicating the validity of the sensing measurement results: "0" indicates that at least one of the m sensing measurement results is invalid, and "1" indicates that all m sensing measurement results are valid; the other bit is the logical AND result of the n bits indicating the correctness of the received communication data: "0" indicates that at least one of the n communication data reception correctness indicators is a reception error indicator (NACK), and "1" indicates that all n communication data reception correctness indicators are reception correct indicators (ACK). For the one bit indicating the validity of the sensing measurement results, it can also be: when more than x (x <= m, when x = m, the effect is equivalent to logical AND) of the m sensing measurement results are valid, feedback "1", otherwise feedback "0".
[0595] Method c: Feedback 1 bit, for example, the logical AND result of the m bits indicating the validity of the sensing measurement results and the n bits indicating the correctness of the received communication data: "0" indicates that at least one of the m sensing measurement results is invalid or at least one of the n communication data reception correctness indicators is a reception error indicator (NACK), and "1" indicates that all m sensing measurement results are valid and all n communication data reception correctness indicators are reception correct indicators (ACK).
[0596] Method d: Feedback m + n - x bits. Among the m sensing measurement result validities and the n communication data reception correctness indicators, there are x (x <= m and x <= n) associated sensing measurement result validities and communication data reception correctness indicators (a total of 2 * x bits). Each pair of the associated 2 bits is logically ANDed to obtain x bits: Each of the x bits is used to indicate the associated sensing measurement result validity and communication data reception correctness: "0" indicates that the communication data reception is incorrect (NACK) or the sensing measurement result is invalid, and "1" indicates that the communication data reception is correct (ACK) and the sensing measurement result is valid; the remaining m - x bits and n - x bits respectively indicate the sensing measurement result validity and the communication data reception correctness; In particular, when there are the following situations: x = m < n, x = n < m, x = m = n, there may be no bits that separately indicate the sensing measurement result validity or the communication data reception correctness. The specific format can refer to 1) a) ii., where the joint coding indication information is 1 bit.
[0597] In mode e, particularly, if there are x (x <= m and x <= n) associated valid perception measurement results and communication data reception correctness indications among the validities of m perception measurement results and the n communication data reception correctness indications (a total of 2 * x bits), the x valid perception measurement result indications are based on the validities of perception measurements of communication data, that is, the target signal is a communication data signal. Each associated 2 bits can also be represented by 1 bit or 2 bits. The method can be as follows:
[0598] When the communication data reception is incorrect, it is represented by 1 bit. "0" indicates that the communication data reception is incorrect (NACK) and the perception measurement result is invalid.
[0599] Alternatively, when the communication data reception is correct, it is represented by 2 bits. One bit is "1" indicating that the communication data reception is correct (ACK), and the other bit is used to indicate whether the perception measurement result is valid.
[0600] It should be noted that the communication data reception correctness indication and the perception measurement result validity indication need to be encoded independently, and the communication data reception correctness indication comes first. (The receiving end first decodes the communication data reception correctness indication information to obtain n communication data reception correctness indication information, and based on how many correct reception indications (ACK) there are among the x communication reception correctness indication information associated with perception, it can determine the number of bits of the subsequent perception measurement result validity indication).
[0601] In mode f, 1 + n bits are fed back, that is, corresponding to the validities of m perception measurement results, the validity of each perception measurement result is represented by u bits (corresponding to v states related to validity, u = ceil(log2(v)) bits are required for representation). For example, the validity of the perception measurement result is divided into different levels, that is, the target indicators corresponding to the measurement results (such as the received power of the perception target associated path, perception SINR, etc.) are different, or there are multiple thresholds for judging the validity of the measurement result. (Assuming there are two thresholds), it can be divided into three states: invalid, valid according to the first threshold but invalid according to the second threshold, and valid according to the second threshold (assuming the second threshold is more stringent). The validities of the perception measurement results and the communication data reception correctness can be indicated by m * u bits and n bits respectively.
[0602] In mode g, 1 + n bits are fed back. One bit can be, for example, the logical AND of the validity indication bits of m perception measurement results ("0" indicates that at least one perception measurement result is invalid, "1" indicates that all m perception measurement results are valid), or, when more than x (x < m) of the m perception measurement results are valid, "1" is fed back, otherwise "0" is fed back. The other n bits are the n communication data reception correctness indication bits.
[0603] Mode h: Feedback m+1 bits, where m bits are m bits indicating the validity of the perception measurement results, and the other bit is the logical AND of n bits indicating the correctness of the communication data reception.
[0604] Format 2: Feedback of valid perception measurement result + perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back, as well as the communication data reception correctness indication; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the communication data reception correctness indication is fed back. Specifically, the format may include the following:
[0605] Mode a: Feedback the perception measurement result each time the validity indication is fed back, and then feedback the communication data reception correctness indication, as shown in the following Table 53:
[0606] Table 53:
[0607] Mode b: First, the n-bit validity indication is fed back, then the perception measurement result is fed back, and then the communication data reception correctness indication is fed back, as shown in the following Table 54:
[0608] Table 54:
[0609] Alternatively, the perception measurement result validity indication and the communication data reception correctness indication may be fed back first, and then the perception measurement result may be fed back, for example, as shown in the following Table 55:
[0610] Table 55:
[0611] Among them, the above feedback format can also be that the communication data reception correctness indication comes first, and the perception measurement result validity indication and perception measurement result come second, that is, high-priority information is placed in front. When the communication feedback is more important, communication is placed in front, otherwise perception is placed in front.
[0612] In addition, according to the description in format 1, the perception measurement result validity indication bit and the communication data reception correctness indication bit may be combined and fed back; or the perception measurement result validity indication may be represented by multiple bits.
[0613] It should be noted that when feeding back perception measurement results, the number of bits for each perception measurement result is fixed. This can be agreed upon by the sender and receiver (as specified in the protocol), or the sender of the first feedback information can indicate the number of bits of the perception measurement result / the number of bits of the first feedback information. In particular, for method b in format 2, the m-bit validity indication precedes the perception result. The validity indication and the perception result can be encoded separately. The receiver first detects the first m-bit validity indication to know the number of perception results. In this case, the receiver only needs to know the number of bits of each perception measurement result to correctly decode. The same applies to the feedback of the reasons for invalid perception measurement results and the recommended target signal parameter configuration.
[0614] Format 3: Feedback of valid perception measurement result + perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + invalid reason + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback is given of the perception measurement result, as well as feedback of the communication data reception correctness indication; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback is given of the invalid reason for the perception measurement result, as well as feedback of the communication data reception correctness indication. Specifically, the format may include the following:
[0615] Mode a: Each time a validity indication is fed back, the perception measurement result or invalid reason is fed back, and then the communication data reception correctness indication is fed back, as shown in the following Table 56:
[0616] Table 56:
[0617] Mode b: First, an m-bit validity indication is fed back, then the perception measurement result and invalid reason are fed back in sequence, and then an indication of the correctness of the communication data reception is fed back, as shown in Table 57 below:
[0618] Table 57:
[0619] The communication data reception correctness indication may also be placed before or after the perception measurement result validity indication, or the two may be fed back alternately, and then the perception measurement result and invalidity reason may be fed back in sequence.
[0620] Mode c: The perception measurement result when the perception measurement result is valid and the invalid reason when the perception measurement result is invalid may be fed back separately, and then the communication data reception correctness indication is fed back. Assuming that there are x valid perception measurement results and y invalid perception measurement results, x perception measurement results and p (p<=y) invalid reasons are fed back, for example, as shown in Table 58 below:
[0621] Table 58:
[0622] It should be noted that information with high importance or high delay requirement can be placed in front. For example, if the perception measurement result is more important, the perception measurement result will be placed in front. The perception measurement result can also be encoded independently.
[0623] Alternatively, the invalidation reason can be placed first, followed by the sensory measurement result. Alternatively, the communication data reception correctness indication can be placed before or after the sensory measurement result validity indication, or both can be fed back alternately. The sensory measurement result and invalidation reason can then be fed back separately, with communication feedback being prioritized when communication is more important, and vice versa. The same applies to the following ordering of sensory measurement results, invalidation reasons, and recommended target signal parameter configurations.
[0624] In addition, according to the description in format 1, the perception measurement result validity indication bit and the communication data reception correctness indication bit may be combined and fed back; or the perception measurement result validity indication may be represented by multiple bits.
[0625] The number of invalidation reasons fed back can be less than the number of invalid perception measurement results, because the same invalidation reason can be fed back only once, or only the invalidation reasons of some invalid perception measurement results can be fed back. Compared with sequentially feeding back perception measurement results and invalidation reasons, this can reduce feedback overhead. However, since the number of feedback information bits is uncertain, the total number of feedback bits or the number of invalidation reasons fed back must be indicated. Otherwise, the receiving end may not be able to correctly decode the first feedback information. The same applies to the feedback of invalidation reasons for perception measurement results below.
[0626] Format 4: Feedback of valid perception measurement result + perception measurement result + communication data reception correctness indication, or feedback of invalid perception measurement result + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back, as well as the communication data reception correctness indication; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the recommended target signal parameter configuration (,) is fed back, as well as the communication data reception correctness indication.
[0627] The specific format is format 3 above, where the invalid reason is replaced by the recommended target signal parameter configuration.
[0628] Among them, the number of recommended parameter configurations fed back can be less than the number of invalid perception measurement results, because the same recommended parameter configuration can be fed back only once or only part of the recommended parameter configuration can be selected for feedback (for example, if the recommended parameter configuration 1 is 100MHz bandwidth and the recommended parameter configuration 2 is 120MHz bandwidth, then only the recommended parameter configuration 2 is fed back). Compared with the method of sequentially feeding back the perception measurement results and the recommended parameter configuration, the feedback overhead can be saved. However, since the number of feedback information bits is uncertain at this time, it is necessary to indicate the total number of feedback bits or the number of recommended target signal parameter configurations fed back, otherwise the receiving end may not be able to correctly decode the first feedback information. The following feedback involving the recommended target signal parameter configuration is similar.
[0629] Format 5, feedback of valid perception measurement result + perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + invalid reason + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and the perception measurement result is fed back, as well as the communication data reception correctness indication; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and the invalid reason for the perception measurement result and the recommended target signal parameter configuration are fed back, as well as the communication data reception correctness indication.
[0630] The specific format is the same as format 3 above, where the invalid reason is replaced with invalid reason + recommended target signal parameter configuration.
[0631] Among them, in addition to the communication data reception correctness indication and the perception measurement result validity indication and the perception measurement result or invalid reason, the order of priority can be determined according to the feedback priority, the invalid reason and the recommended target signal parameter configuration can also be determined according to the importance (in this case, the two can be independently encoded).
[0632] Format 6, feedback of valid perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + invalid reason + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback of communication data reception correctness indication is given; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of the invalid reason for the perception measurement result and feedback of communication data reception correctness indication is given.
[0633] The specific format is the above-mentioned format 3, wherein the perception measurement result is no longer fed back when the perception measurement result is valid.
[0634] Format 7, feedback of valid perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback of communication data reception correctness indication is given; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of recommended target signal parameter configuration and feedback of communication data reception correctness indication is given.
[0635] The specific format is the same as format 3 above, where the perception measurement result is no longer fed back when it is valid, and the invalid reason is replaced by the recommended target signal parameter configuration.
[0636] Format 8, feedback of valid perception measurement result + communication data reception correctness indication or feedback of invalid perception measurement result + invalid reason + recommended target signal parameter configuration + communication data reception correctness indication: When the perception measurement result is valid, feedback "1" indicates that the perception result is valid, and feedback of communication data reception correctness indication is given; when the perception measurement result is invalid, feedback "0" indicates that the perception result is invalid, and feedback of recommended target signal parameter configuration and feedback of communication data reception correctness indication is given.
[0637] The specific format is the same as the above format 5, wherein the perception measurement result is no longer fed back when the perception measurement result is valid.
[0638] Format 9. Only when the first perception measurement result is valid, the first feedback information sent by the second device to the first device includes a perception measurement result validity indication of the first perception measurement result or the perception measurement result or target signal identification information associated with the perception measurement result or perception measurement identification information; when the measurement result is invalid, the first feedback information does not include relevant feedback information of the first perception measurement result, and the first perception measurement result is 1 of the m perception measurement results.
[0639] Only when the first perception measurement result is invalid, the first feedback information sent by the second device to the first device includes a perception measurement result validity indication of the first perception measurement result or a reason for invalidity of the perception measurement result or a recommended target signal parameter configuration; when the measurement result is valid, the first feedback information does not include relevant feedback information of the first perception measurement result, and the first perception measurement result is 1 of the m perception measurement results.
[0640] In the perception measurement result feedback method provided in an embodiment of the present application, a first device performs perception measurement based on indication information related to a perception measurement signal configuration, provides feedback on the validity of the perception measurement result and the correctness of communication data reception, and provides feedback on information such as the perception measurement result, the reason for the invalid perception measurement result, and a recommended perception measurement signal configuration based on the validity of the perception measurement result.
