[0086] In some embodiments, the sensing network function can also be called a sensing network element or sensing management function (Sensing MF). It can be located on the RAN side or the core network side. It refers to a network node in the core network or RAN that is responsible for at least one of the following functions: sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing.

[0092] The following description, in conjunction with the accompanying drawings, details the measurement result transmission method, reception method, apparatus, and equipment provided in the embodiments of this application through some examples and application scenarios.

[0093] Please refer to Figure 3, which is a flowchart of a measurement result transmission method provided in an embodiment of this application. As shown in Figure 3, it includes the following steps:

[0094] Step 301: The first device sends measurement results to the second device. The measurement results include measurement information for N target sampling points. The measurement information for the N target sampling points is sorted according to the measurement indicators of the N target sampling points. The measurement information includes at least one of the following:

[0095] The location information of the target sampling point;

[0096] The Doppler information or velocity information of the target sampling point;

[0097] The time delay information or distance information of the target sampling point;

[0098] The angle information of the target sampling point;

[0099] Wherein, N is a positive integer.

[0100] The first device can be a terminal or a network-side device, and the second device can be a terminal or a network-side device. For example, if the first device is a terminal, the second device can be a terminal or a network-side device; if the first device is a network-side device, the second device can be a terminal or a network-side device.

[0101] The second device mentioned above can be a device that calculates the final result based on the above measurement results, or it can be a device that sends the above measurement results to other devices, and the other devices calculate the final result based on the above measurement results. The final result can be a sensing result, a communication result, or a sensing and communication integrated result.

[0102] The measurement information of the above N target sampling points is the measurement information obtained by the first device measuring the signal (which can be called the first signal). The signal can be a sensing signal or a communication signal, or an integrated sensing and communication signal. The above signal can be sent to the first device by other devices, such as a third device sending it to the first device, or a signal sent by the first device, that is, the first device sends and receives the signal itself.

[0103] The aforementioned N target sampling points are part of the sampling points in the first domain, wherein the first domain may include at least one of the time delay domain, range domain, Doppler domain, velocity domain, azimuth domain and pitch domain; or, the first domain may include a domain combining at least two of the time delay domain, range domain, Doppler domain, velocity domain, azimuth domain and pitch domain. For example, the channel response H(f) obtained from signal measurement, where f = 0, 1, 2, ..., K-1 represents different frequency domain resource units, such as subcarrier indices, can be transformed to the time delay domain (i.e., the first domain) by performing an inverse Fourier transform on the channel response H(f), thus obtaining multiple sampling points in the first domain. Similarly, the channel response H(f,t) obtained from signal measurement, where f = 0, 1, 2, ..., K-1 represents frequency domain resource units, such as subcarrier indices, and t = 0, 1, 2, ..., M-1 represents time domain resource units, such as OFDM symbol indices, can be transformed to the time delay-Doppler domain (i.e., the first domain) by performing an inverse Fourier transform along the frequency domain and a Fourier transform along the time domain on the channel response H(f,t), thus obtaining multiple sampling points in the first domain.

[0104] The location information of the target sampling point can be determined based on the information of the target sampling point in the first domain (such as time delay, range, Doppler, velocity, phase, azimuth angle and pitch angle, at least one of these). The phase is the basic information of the sampling point in each domain, that is, each domain can include the phase information of the sampling point. For example, the time delay domain can include the phase information of the sampling point in addition to the time delay information. The Doppler domain can include the phase information of the sampling point in addition to the Doppler information. The velocity domain can include the phase information of the sampling point in addition to the velocity information.

[0105] The Doppler information or velocity information of the target sampling point mentioned above can be the information of the target sampling point in the Doppler domain or velocity domain, or, if the first domain is not the Doppler domain or velocity domain, the Doppler information or velocity information determined based on the information in the first domain (such as time delay, range, phase, azimuth angle and pitch angle, at least one of them).

[0106] The time delay information or distance information of the target sampling point mentioned above can be the information of the target sampling point in the time delay domain or the distance domain, or, if the first domain is not the time delay domain or the distance domain, the time delay information or distance information determined based on the information in the first domain (such as at least one of Doppler, velocity, phase azimuth angle and pitch angle).

[0107] The angle information of the target sampling point mentioned above can be the information of the target sampling point in the azimuth domain and the elevation domain, or the angle information determined based on the information in the first domain (such as time delay, range, phase, Doppler and velocity, if the first domain is not the azimuth domain and the elevation domain). For example, if the first domain is the time delay-Doppler domain, the target sampling point can be found in the time delay-Doppler domain, and then the angle information can be calculated based on the phase information of the target sampling point in the first domain of multiple receiving antenna ports.

[0108] In some implementations, the distance information described above may be the distance R relative to the signal transmitting device (such as a third device). T Or the distance R relative to the signal receiving device (i.e., the first device mentioned above). R The distance is either the sum of the distances relative to the signal transmitting device (such as the third device) and the receiving device (i.e., the first device mentioned above), or the signal propagation distance R = c·τ or R = c·τ / 2 calculated based on the time delay information, where c is the speed of light and τ is the time delay information.

[0109] In some implementations, when the first domain is a time-delay-Doppler domain, after detecting the target sampling point in the time-delay-Doppler domain, the time delay τ of the target sampling point i can be determined. i or Doppler f di Therefore, the distance d from the target sampling point i can be calculated. i Or radial velocity v i Taking monostatic sensing as an example Where c represents the speed of light, f c This represents the carrier frequency. Additionally, the complex channel response H(f) of the target sampling point i on the time-delay-Doppler spectrum corresponding to different receiving antenna ports can also be used. di ,τ i (or phase information) can be used to calculate the angle of arrival information of the target sampling point, including the azimuth angle of arrival AoA. i And the zenith angle of arrival (zoA) i Alternatively, based on the channel response complex value H(f) of the target sampling point i on the delay-Doppler spectrum corresponding to different transmitting antenna ports or different transmitting signal resources. di ,τ i Alternatively, phase information can be used to calculate the departure angle information of the target sampling point, including the azimuth departure angle (AoD). i ZoD (Zenith Departure Angle) i .

[0110] In some implementations, the angle information may include angle information in a local coordinate system or angle information in a global coordinate system.

[0111] In some implementations, the measurement information may also include Doppler information and velocity information of the target sampling point.

[0112] In some implementations, the measurement information may also include time delay information and distance information of the target sampling point.

[0113] The measurement indicators for the above N target sampling points can be relevant indicators of the signal, such as signal strength or signal-to-noise ratio.

[0114] The above-mentioned sorting of the measurement information of the N target sampling points in the measurement results according to the measurement indicators of the N target sampling points can be sorted in ascending or descending order according to the measurement indicators of the N target sampling points, or it can be sorted according to the interval range to which the measurement indicators of the N target sampling points belong. For example, the measurement information of target sampling points whose measurement indicators belong to the same interval range is arranged together, and the measurement information of target sampling points with different interval ranges is sorted in order.

[0115] In some implementations, the measurement results can be transmitted once or multiple times. If multiple transmissions are made, they can be transmitted in the order described above.

[0116] The second device can determine the relevant information of the measurement indicators of the above N target sampling points based on the sorting of the measurement information of the above N target sampling points, such as the order of magnitude or range of the measurement indicators of the N target sampling points.

[0117] The value of N can be agreed upon by the protocol, configured by the network-side device, or determined by the first device mentioned above. There are no restrictions on this value, such as 1, 2, 3, or 5.

[0118] In this embodiment, since the measurement results include measurement information of N target sampling points, it is possible to send the measurement information of N target sampling points without sending the measurement information of all sampling points, thereby reducing the transmission overhead of the measurement results. In addition, since the measurement information of N target sampling points in the measurement results is sorted according to the measurement indicators of the N target sampling points, the measurement indicators of the N target sampling points are indicated by the sorting of the measurement information of the N target sampling points, that is, no additional information is needed to indicate the measurement indicators of the N target sampling points, further reducing the transmission overhead.

[0119] As an optional implementation, the measurement result may also include information on the number of target sampling points.

[0120] The aforementioned number information refers to the value of N. This number information allows the second device to determine the number of target sampling points in a timely manner, thereby avoiding the second device from performing additional signal monitoring activities and saving power consumption.

[0121] As an optional implementation, the target sampling points include: sampling points in the first domain that satisfy the first condition; or,

[0122] The target sampling points include: sampling points obtained by clustering sampling points in the first domain that satisfy the first condition, wherein there is only one target sampling point for the same class;

[0123] The first domain includes multiple sampling points.

[0124] In some implementations, the first domain may include at least one of a time delay domain, a range domain, a Doppler domain, a velocity domain, an azimuth domain, and a pitch domain; or, the first domain may include a domain combining at least two of the time delay domain, range domain, Doppler domain, velocity domain, azimuth domain, and pitch domain. It should be noted that, in the embodiments of this application, the first domain is not limited to the above, and may specifically be a domain related to sensing or communication.

[0125] The aforementioned first condition may be a condition agreed upon in the agreement or configured by the network-side equipment, or a condition pre-negotiated between the aforementioned first equipment and the aforementioned second equipment, or a condition determined by the aforementioned first equipment itself.

[0126] The first condition described above allows for the selection of N target sampling points in the first domain, thereby reducing the overhead of measurement result transmission.

[0127] It should be noted that the embodiments of this application are not limited to determining N target sampling points through the above-mentioned first condition. For example, in some implementations, the above-mentioned N target sampling points may also be N target sampling points selected by the first device based on business needs, environment, or measurement results.

[0128] The sampling points obtained by clustering the sampling points that satisfy the first condition in the first domain can be obtained by clustering the sampling points that satisfy the first condition in the first domain to obtain at least one class, each class including at least one sampling point that satisfies the first condition, and then determining one sampling point in each class, i.e., the target sampling point.

[0129] In this embodiment of the application, the above-mentioned class can also be understood as a cluster.

[0130] In some implementations, the target sampling point is one of multiple sampling points in the same class, that is, a sampling point is selected as the target sampling point; or, the target sampling point is a sampling point obtained by weighting multiple sampling points in the same class, wherein the weighting weight can be agreed upon by the protocol or configured by the network-side device.

[0131] For example, constant false alarm rate (CFAR) detection is performed on the sampling points. The first condition mentioned above is that the amplitude or power exceeds a preset threshold as determined by CFAR detection. As shown in Figure 4, the sampling points whose amplitude or power exceeds the preset threshold are sampling point 0, sampling point 0a, sampling point 1, sampling point 1a, and sampling point 2. They are clustered. Sampling point 0 and sampling point 0a have the same cluster label, and sampling point 1 and sampling point 1a have the same cluster label. Finally, the sampling point with the largest amplitude or power is selected from the sampling points with the same cluster label as the target sampling point, that is, target sampling point 0, target sampling point 1, and target sampling point 2 are obtained. Alternatively, sampling points with the same cluster label can be weighted and merged to obtain the target sampling point. For example, sampling points 0 and 0a can be weighted and merged according to their amplitude or power to obtain target sampling point 0', and sampling points 1 and 1a can be weighted and merged according to their amplitude or power to obtain target sampling point 1'. Finally, target sampling point 0', target sampling point 1' and target sampling point 2' (i.e. sampling point 2, because the cluster containing sampling point 2 only has one sampling point, so the sampling points in this cluster are weighted and merged to obtain target sampling point 2', which is sampling point 2).

[0132] Since the target sampling points are obtained by clustering the sampling points in the first domain that satisfy the first condition, the number of target sampling points can be further reduced, so as to better reduce the transmission overhead of the measurement results.

[0133] In some implementations, the first condition includes at least one of the following:

[0134] The amplitude of the sampling points meets the preset amplitude condition;

[0135] The power at the sampling points meets the preset power condition;

[0136] The Doppler readings at the sampling points meet the preset Doppler conditions;

[0137] The speed of the sampling points meets the preset speed conditions;

[0138] The time delay of the sampling points meets the preset time delay condition;

[0139] The distance between the sampling points meets the preset distance condition;

[0140] The angle of the sampling point meets the preset angle condition;

[0141] The phase of the sampling point satisfies the preset phase condition;

[0142] The difference between the parameters of the sampling point and the parameters of the reference sampling point satisfies a preset difference condition. The parameters include at least one of amplitude, power, Doppler, velocity, time delay, distance, and angle.

[0143] The aforementioned preset conditions may be agreed upon by the protocol or configured by the network-side device, or determined by the aforementioned first device, and there are no restrictions on this.

[0144] In some implementations, the preset amplitude condition includes at least one of the following: amplitude exceeding a preset amplitude threshold, amplitude being within a preset amplitude range, amplitude being greater than the amplitude of a sampling point within the first interval range of the first domain, and amplitude satisfying a preset modulation rule.

[0145] In some implementations, the preset power conditions include at least one of the following: power exceeding a preset power threshold, power being within a preset power range, power being greater than the power of a sampling point within the second range of the first domain, and power satisfying a preset modulation rule.

[0146] In some implementations, the preset Doppler condition includes at least one of Doppler exceeding a preset Doppler threshold and Doppler being located within a preset Doppler range;

[0147] In some implementations, the preset speed condition includes at least one of the following: the speed exceeds a preset speed threshold and the speed is within a preset speed range.

[0148] In some implementations, the preset delay condition includes at least one of the following: the delay exceeds a preset delay threshold and the delay is within a preset delay interval.

[0149] In some implementations, the preset distance condition includes at least one of the following: the distance exceeds a preset distance threshold and the distance is within a preset distance range.

[0150] In some implementations, the preset angle condition includes at least one of the following: the angle exceeds a preset angle threshold and the angle is within a preset angle range.

[0151] In some implementations, the preset phase condition includes the phase satisfying a preset modulation rule.

[0152] The aforementioned preset modulation rules may be agreed upon by the protocol or configured by the network-side device, or determined by the aforementioned first device. For example, the aforementioned preset modulation rules are the modulation rules of tags, backscatter, or reconfigurable intelligence surfaces (RIS), that is, the aforementioned sampling points that satisfy the aforementioned first condition are sampling points associated with the path reflected by the tag, backscatter device, or RIS.

[0153] The aforementioned reference sampling points may be agreed upon by the protocol or configured by the network-side equipment, or determined by the aforementioned first equipment. There are no limitations on this. For example, sampling points in the first domain associated with the line of sight (LOS) path or the first path of arrival, or sampling points associated with the reference path, or the path reflected by a known target, such as sampling points associated with the path reflected by RIS, backscatter, or other known passive targets.

[0154] In some implementations, the above parameters can be obtained by CFAR detection, such as power or amplitude parameters obtained by CFAR detection.

[0155] The target sampling points can be determined from one or more dimensions based on the first condition mentioned above, in order to meet the needs of more scenarios or businesses and improve the compatibility of measurements.

[0156] As an optional implementation, the measurement index includes at least one of the following:

[0157] Received power or signal strength;

[0158] Signal-to-interference-plus-noise ratio (SINR) or signal-to-noise ratio (SNR);

[0159] Signal-to-clutter ratio.

[0160] The aforementioned received power or signal strength refers to the received power or signal strength of the aforementioned target sampling point; the aforementioned signal-to-interference-plus-noise ratio (SINR) refers to the SINR of the aforementioned target sampling point; and the aforementioned signal-to-clutter ratio refers to the signal-to-clutter ratio of the aforementioned target sampling point.

[0161] In this embodiment, the measurement information of N target sampling points can be sorted according to at least one of the above-mentioned measurement indicators. This sorting can indicate at least one of the above-mentioned measurement indicators, so that the first device can transmit more measurement-related information to the second device. Since no additional indication is required, the transmission overhead is reduced.

[0162] In some implementations, the received power or signal strength includes: the linear average of the power of the channel response corresponding to the target sampling point; or, the total power of the channel response corresponding to the target sampling point.

[0163] Wherein, the linear average power of the channel response corresponding to the target sampling point can refer to the linear average power of the channel response corresponding to the target sampling point across multiple resource units (such as multiple frequency domain resource units or time domain resource units); the total power of the channel response corresponding to the target sampling point can refer to the total power of the channel response corresponding to the target sampling point across multiple resource units (such as multiple frequency domain resource units or time domain resource units).

[0164] Since the received power includes the linear average of the power of the channel response corresponding to the target sampling point, this ensures that the received power of the sampling point is fair under different signal configurations, thus making the received power more reliable.

[0165] In some implementations, the signal strength includes: the linear average of the signal strength of the channel response corresponding to the target sampling point.

[0166] Since the signal strength includes the linear average of the signal strength of the channel response corresponding to the target sampling point, this ensures that the signal strength of the sampling point is fair under different signal configurations, thus making the signal strength more reliable.

[0167] In some implementations, the signal-to-interference-plus-noise ratio (SINR) is equal to the linear average of the power of the channel response corresponding to the target sampling point divided by the linear average of the first power; or, the SINR is equal to the total power of the channel response corresponding to the target sampling point divided by the second power, wherein the first power includes the power of noise and interference, and the second power is the total power of noise and interference.

[0168] The first power mentioned above can refer to the power of noise and interference, which is generated by noise and interference. One first power can correspond to one resource unit (such as one frequency domain resource unit or time domain resource unit). The linear average value of the first power is the linear average value of the power of noise and interference, such as the linear average value of the sum of the power of noise and interference on multiple resource units. The total power of noise and interference mentioned above can refer to the total power of noise and interference on multiple resource units (such as multiple frequency domain resource units or time domain resource units), that is, the total power is the sum of the power of noise and interference on multiple resource units (without linear averaging).

[0169] Since the signal-to-interference-plus-noise ratio (SIR) is equal to the linear average of the channel response power corresponding to the target sampling point divided by the linear average of the first power, this ensures that the SIR of the sampling points is fair under different signal configurations, thus making the SIR more reliable.

[0170] In some implementations, the signal-to-noise ratio is equal to the linear average power of the channel response corresponding to the target sampling point divided by the linear average power of the noise, or the signal-to-interference-plus-noise ratio is equal to the total power of the channel response corresponding to the target sampling point divided by the total power of the noise.

[0171] The aforementioned noise power may refer to the noise power on a single resource unit (such as a frequency domain resource unit or a time domain resource unit); the aforementioned total noise power may refer to the total noise power on multiple resource units (such as multiple frequency domain resource units or time domain resource units).

[0172] Since the signal-to-noise ratio (SNR) is equal to the linear average of the power of the channel response corresponding to the target sampling point divided by the linear average of the power of the noise, this ensures that the SNR of the sampling points is fair under different signal configurations, thus making the SNR more reliable.

[0173] In some implementations, the signal-to-clutter ratio is equal to the linear average of the channel response power corresponding to the target sampling point divided by the linear average of the clutter power; or, the signal-to-interference-plus-noise ratio is equal to the total power of the channel response corresponding to the target sampling point divided by the total clutter power.

[0174] The linear average value of the clutter power can refer to the linear average value of the clutter power of the channel response corresponding to the target sampling point across multiple resource units (such as multiple frequency domain resource units or time domain resource units); the total clutter power can refer to the total clutter power of the channel response corresponding to the target sampling point across multiple resource units (such as multiple frequency domain resource units or time domain resource units).

[0175] Since the signal-to-clutter ratio is equal to the linear average of the channel response power corresponding to the target sampling point minus the linear average of the clutter power, this ensures that the signal clutter at the sampling point is fair under different signal configurations, thus making the signal clutter more reliable.

[0176] In some embodiments, the clutter power includes the power of the channel response corresponding to at least one non-target sampling point in the first domain; and / or, the total clutter power includes the total power of the channel response corresponding to at least one non-target sampling point in the first domain.

[0177] The above non-target sampling points are sampling points in the first domain that are not target sampling points.

[0178] The aforementioned at least one non-target sampling point can be one or more sampling points adjacent to the aforementioned target sampling point. In the case of multiple sampling points, the power of the channel response corresponding to the aforementioned at least one non-target sampling point can be the average power of the channel response corresponding to these multiple sampling points, and the total power of the channel response corresponding to the aforementioned at least one non-target sampling point can be the total power of the channel response corresponding to these multiple sampling points.

[0179] Since the clutter power includes the power of the channel response corresponding to at least one non-target sampling point in the first domain, or the total clutter power includes the total power of the channel response corresponding to at least one non-target sampling point in the first domain, the signal-to-clutter ratio of the target sampling point can be made more reliable.

[0180] As an optional implementation, the method further includes:

[0181] The first device receives indication information, the indication information being used to indicate at least one of the following:

[0182] The number of target sampling points;

[0183] The maximum number of target sampling points allowed;

[0184] The relevant information of the first condition, wherein the target sampling point satisfies the first condition;

[0185] The filtering information of the first domain, wherein the target sampling point is a sampling point selected after filtering the first domain with the filtering information.

[0186] The aforementioned first instruction information may be received from a second device or from a third device.

[0187] The value of N can be equal to the number of target sampling points, or the value of N can be determined based on the number of target sampling points. For example, the above indication information indicates that the number of target sampling points is 2, but the first device increases the number of N by 1 based on its own or measurement needs, and determines the value of N to be 3, so as to better meet the measurement needs.

[0188] The maximum number of target sampling points is the maximum possible value of N, meaning that the value of N cannot exceed this maximum number. This maximum number effectively limits the number of target sampling points, thus saving the transmission overhead of measurement results.

[0189] The relevant information for the first condition may be information used to determine the first condition, or the target information may explicitly indicate the first condition, i.e., the condition information of the first condition.

[0190] In some implementations, the relevant information for the first condition mentioned above includes at least one of the following: threshold factor, false alarm probability, CFAR detection type, protection cell length, and reference cell length.

[0191] The threshold factor mentioned above can be a threshold factor used to determine at least one of the following:

[0192] Preset amplitude conditions;

[0193] Preset power conditions;

[0194] Preset Doppler conditions;

[0195] Preset speed conditions;

[0196] Preset delay conditions;

[0197] Preset distance conditions;

[0198] Preset angle conditions;

[0199] Preset phase conditions;

[0200] Preset difference conditions.

[0201] The aforementioned false alarm probability, CFAR detection type, protection cell length, and reference cell length can be CFAR detection threshold information, i.e., used to determine the CFAR detection threshold. This threshold can specifically be at least one of the following:

[0202] Preset amplitude threshold;

[0203] Preset power threshold;

[0204] Preset Doppler threshold;

[0205] Preset speed threshold;

[0206] Preset delay threshold;

[0207] Preset distance threshold;

[0208] Preset angle threshold;

[0209] Preset phase threshold;

[0210] Preset difference threshold.

[0211] For example, as shown in Figure 5, for the detection of a specific sampling point to be detected in the first domain (represented as the unit to be detected in Figure 5), the signal power or amplitude of several nearby reference units (determined according to the length of the protection unit and the reference unit) is estimated as the clutter or noise power or amplitude at the sampling point to be detected, which is used to set the detection threshold of the sampling point to be detected. For example, by multiplying the clutter or noise power or amplitude by the threshold factor, the threshold value for detecting the sampling point to be detected is obtained.

[0212] The first condition can be dynamically configured using the relevant information provided above, so that the measurement information of the target sampling point determined based on the first condition is more reliable.

[0213] The filtering information of the first domain mentioned above can be filtering information used to determine a specific range of the first domain. For determining the Doppler range or time delay range, it can include at least one of the minimum Doppler value, maximum Doppler value, minimum time delay value, and maximum time delay value.

[0214] In this way, the sampling points in the first domain can be filtered using the filtering information in the first domain. Therefore, the target sampling point only needs to be determined from the remaining sampling points after filtering, which reduces the complexity of determining the target sampling point and saves device power consumption.

[0215] As an optional implementation, the measurement information of the N target sampling points in the measurement results, ordered according to the measurement indicators of the N target sampling points, includes:

[0216] The measurement information of the N target sampling points is sorted in ascending or descending order according to the measurement indicators of the N target sampling points; or...

[0217] Different types of measurement information are sorted in ascending or descending order according to the measurement indicators of the N target sampling points.

[0218] The above-mentioned different types of measurement information can be sorted in ascending or descending order according to the measurement indicators of the N target sampling points. This can be done by sorting the different types of measurement information in chronological order, where each type of measurement information is sorted in ascending or descending order according to the measurement indicators of the N target sampling points.

[0219] For example: first, sort the first type of measurement information among the measurement information of the N target sampling points in ascending order according to the measurement index of the N target sampling points, and then sort the second type of measurement information among the measurement information of the N target sampling points in ascending order according to the measurement index of the N target sampling points.

[0220] For example: first, sort the first type of measurement information among the measurement information of the N target sampling points in descending order according to the measurement index of the N target sampling points, and then sort the second type of measurement information among the measurement information of the N target sampling points in descending order according to the measurement index of the N target sampling points.

[0221] The measurement information of the above N target sampling points can be sorted in ascending order according to the measurement index of the N target sampling points, which means that the measurement index of the first target sampling point is the lowest, and then the measurement index increases in turn; the measurement information of the above N target sampling points can be sorted in descending order according to the measurement index of the N target sampling points, which means that the measurement index of the first target sampling point is the highest, and then the measurement index decreases in turn.

[0222] By sorting the measurement indicators of the N target sampling points in ascending or descending order as described above, the relationship between the measurement indicators of the N sampling points can be effectively indicated. For example, for location information, the measurement results reported by the first device are in the format: {number of target sampling points N; (x0,y0,z0), (x1,y1,z1), ..., (x N-1 ,y N-1 ,z N-1 For location information and Doppler information, the measurement results reported by the first device are in the following format: {Number of target sampling points N; {(x0,y0,z0), f} d0},{(x1,y1,z1),fd1}, ..., {(x N-1 , y N-1 , z N-1 ), F dN-1}}; wherein, x, x, z represent position information, f d represents Doppler information, and for any target sampling point n1 and target sampling point n2, 0≤n1<n2≤N-1 is the index or sequence number of the sampling point. The measurement index I1 of sampling point n1 and the measurement index I2 of sampling point n2 satisfy I1≥I2 or I1≤I2. It should be noted that the number of target sampling points N in the format of the reported measurement result in this embodiment is optional, that is, the format of the reported measurement result may also not include the number of target sampling points N.

[0223] The above-mentioned first measurement information and second measurement information may be any two measurement information included in the measurement information, for example, any two of the following measurement information:

[0224] position information of the target sampling point;

[0225] Doppler information or velocity information of the target sampling point;

[0226] time delay information or distance information of the target sampling point;

[0227] angle information of the target sampling point.

[0228] For position information and Doppler information, the format of the measurement result reported by the first device is: {number of target sampling points N; (x0,y0,z0), (x1,y1,z1), ..., (x N-1 , y N-1 , z N-1 ); f d0 , f d1 , ..., f dN-1}; wherein, x, x, z represent position information, f d represents Doppler information, and for any target sampling point n1 and target sampling point n2, 0≤n1<n2≤N-1 is the index or sequence number of the sampling point. The measurement index I1 of sampling point n1 and the measurement index I2 of sampling point n2 satisfy I1≥I2 or I1≤I2. It should be noted that the number of target sampling points N in the format of the reported measurement result in this embodiment is optional, that is, the format of the reported measurement result may also not include the number of target sampling points N.

[0229] It should be noted that if there are three or more types of measurement information, these types of measurement information can be sorted with reference to the first and second types of measurement information mentioned above. For example, if the measurement results include three types of measurement information, firstly, sort the first type of measurement information among the N target sampling points in ascending or descending order according to the measurement indicators of the N target sampling points; then, sort the second type of measurement information among the N target sampling points in ascending or descending order according to the measurement indicators of the N target sampling points; finally, sort the third type of measurement information among the N target sampling points in ascending or descending order according to the measurement indicators of the N target sampling points. The measurement information from the N target sampling points can be sorted in two ways: first, the first type of measurement information is sorted in ascending or descending order according to the measurement indicators of the N target sampling points; then, the second type of measurement information is sorted in ascending or descending order according to the measurement indicators of the N target sampling points; after the second type of measurement information, the third type of measurement information is sorted in ascending or descending order according to the measurement indicators of the N target sampling points; and finally, the fourth type of measurement information is sorted in ascending or descending order according to the measurement indicators of the N target sampling points. If the measurement results include more types of measurement information, the sorting method for the measurement information of the N target sampling points is followed accordingly.

[0230] In the above embodiments, since the measurement information is sorted according to its type, the second device can better determine the various measurement information, thereby reducing the complexity of the second device acquiring multiple measurement information.

[0231] As an optional implementation, the method further includes:

[0232] The first device sends the measurement indicators of the N target sampling points to the second device.

[0233] The measurement indicators of the aforementioned N target sampling points can be sent actively by the first device or requested by the second device from the first device. For example, after receiving the above measurement results, the second device determines the relationship between the measurement indicators of the N sampling points based on the above sorting, and needs to further obtain the measurement indicators of the N target sampling points based on the measurement information of the N sampling points, thereby requesting the first device to send the measurement indicators of the N target sampling points.

[0234] In this embodiment, since the measurement indicators of the above-mentioned N target sampling points are sent to the second device, the second device can obtain more accurate measurement indicators, which is beneficial to improving measurement performance.

[0235] In some implementations, the first device does not send the measurement parameters of the N target sampling points to the second device.

[0236] In this embodiment, a first device sends measurement results to a second device. The measurement results include measurement information for N target sampling points. The measurement information for the N target sampling points is sorted according to their measurement indicators. The measurement information includes at least one of the following: position information of the target sampling points; Doppler information or velocity information of the target sampling points; time delay information or distance information of the target sampling points; and angle information of the target sampling points; where N is a positive integer. Since the measurement results include measurement information for N target sampling points, it is possible to send the measurement information for N target sampling points without needing to send the measurement information for all sampling points, thereby reducing the transmission overhead of the measurement results. Furthermore, since the measurement information for the N target sampling points is sorted according to their measurement indicators, the sorting of the measurement information for the N target sampling points indicates the measurement indicators of the N target sampling points, meaning that no additional information is needed to indicate the measurement indicators of the N target sampling points, further reducing transmission overhead.

[0237] Please refer to Figure 6, which is a flowchart of another measurement result receiving method provided in an embodiment of this application. As shown in Figure 6, it includes the following steps:

[0238] Step 601: The second device receives the measurement results sent by the first device. The measurement results include measurement information of N target sampling points. In the measurement results, the measurement information of the N target sampling points is sorted according to the measurement indicators of the N target sampling points. The measurement information includes at least one of the following:

[0239] The location information of the target sampling point;

[0240] The Doppler information or velocity information of the target sampling point;

[0241] The time delay information or distance information of the target sampling point;

[0242] The angle information of the target sampling point;

[0243] Wherein, N is a positive integer.

[0244] Optionally, the measurement result may also include information on the number of target sampling points.

[0245] Optionally, the target sampling points include: sampling points in the first domain that satisfy the first condition; or,

[0246] The target sampling points include: sampling points obtained by clustering sampling points in the first domain that satisfy the first condition, wherein there is only one target sampling point for the same class;

[0247] The first domain includes multiple sampling points.

[0248] Optionally, the target sampling point is one of multiple sampling points in the same class, or the target sampling point is a sampling point obtained by weighting multiple sampling points in the same class.

[0249] Optionally, the first domain includes at least one of the time delay domain, range domain, Doppler domain, velocity domain, azimuth domain, and pitch domain; or, the first domain includes a domain combining at least two of the time delay domain, range domain, Doppler domain, velocity domain, azimuth domain, and pitch domain.

[0250] Optionally, the first condition includes at least one of the following:

[0251] The amplitude of the sampling points meets the preset amplitude condition;

[0252] The power at the sampling points meets the preset power condition;

[0292] Taking measurement as an example of sensing, the method provided by the embodiments of the present application is illustrated through multiple embodiments:

[0293] Embodiment 1:

[0294] This embodiment provides a measurement result reporting method, the specific features include:

[0295] A first device sends a measurement result to a second device, the measurement result includes measurement information of N target sampling points, and the measurement information of a target sampling point includes at least one of the following:

[0301] Wherein, the information of the target sampling points is information of the target sampling points sorted according to measurement indicators associated with the target sampling points.

[0302] For example, the measurement result sent by the first device to the second device is: {number of sampling points N; sampling point 0 information, sampling point 1 information, ..., sampling point N-1 information}. Wherein, for any sampling point n1 and sampling point n2, 0≤n1<n2≤N-1 is the index or sequence number of the sampling points, and the measurement index I1 of sampling point n1 and the measurement index I2 of sampling point n2 satisfy I1≥I2 or I1≤I2.

[0303] In some embodiments, the target sampling point is a sampling point that satisfies a first condition in a first domain, for example: a sampling point whose power determined after CFAR detection in the time delay-Doppler domain or range-velocity domain meets the CFAR threshold requirement, which can also be called a target scattering point or a target path.

[0304] In some embodiments, the first domain includes at least one of the following:

[0310] In some implementations, the first condition mentioned above includes at least one of the following:

[0311] If the amplitude or power of a sampling point exceeds a preset threshold or falls within a preset range, such as the preset threshold being the CFAR (Constant False Alarm Rate) detection threshold; further filtering can be performed on sampling points that meet the criteria of exceeding the preset threshold or falling within a preset range, such as performing clustering processing, selecting at least one as the target sampling point from multiple sampling points associated with the same target (with the same cluster label or cluster label after clustering), or merging multiple sampling points associated with the same target (with the same cluster label or cluster label after clustering), such as weighted merging, to obtain the target sampling point.

[0315] The amplitude, power, or phase of the sampling point satisfies a specific modulation rule, which is the modulation rule of the Tag, backscatter device, or RIS, that is, the sampling point is a sampling point associated with the path reflected by the Tag, backscatter device, or RIS.

[0316] In some implementations, the measurement metrics include at least one of the following:

[0317] Received power or signal strength indicators;

[0318] Signal-to-interference-plus-noise ratio (SIR / NOT) or signal-to-noise ratio specification;

[0320] In some implementations, it also includes:

[0321] The first device sends measurement parameters associated with the target sampling point to the second device.

[0322] In some embodiments, before the first device sends the measurement result to the second device, the method further includes the first device receiving indication information sent by the second device, the indication information including at least one of the following:

[0323] Limits on the number or maximum number of target sampling points;

[0324] CFAR detection threshold information, including at least one of the following: threshold factor, false alarm probability, CFAR detection type, protection cell length, and reference cell length;

[0325] The first domain filtering information, such as the Doppler range or time delay range, includes at least one of the minimum Doppler value, maximum Doppler value, minimum time delay value, and maximum time delay value.

[0326] In this embodiment, the first device and the second device can be as follows:

[0327] The first device is a terminal, and the second device is a base station (or TRP); the first device is a base station, and the second device is a terminal; or both the first and second devices are base stations; or both the first and second devices are terminals. The second device can also be a core network sensing network function or sensing network element, or it can be other core network network functions or network elements.

[0328] Specifically, signaling transmission between base stations and terminals, and between terminal A and terminal B, can be via RRC signaling, MAC CE, Layer 1 signaling, or other newly defined sensing signaling; signaling transmission between sensing network functions and terminals can be via NAS signaling (forwarded via AMF) and / or via Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE), Layer 1 signaling, or other newly defined sensing signaling; interaction between sensing network functions and base stations can be via AMF forwarding to the radio access network through the N2 interface; or the core network sensing network function sends the signal to the UPF, and the UPF sends it to the radio access network through the N3 interface; or it sends it to the radio access network (base station) through a newly defined interface; signaling transmission between base stations can be via the Xn interface.

[0329] Example 2:

[0330] This embodiment mainly describes the acquisition of measurement results and the calculation of sensing results.

[0331] In this embodiment, the measurement results include time delay, Doppler, angle information, or sampling point location information, and the sensing result is the location information of the sensing target. The specific process of receiving the sensing signal and measuring to obtain the measurement result, and calculating the sensing result based on the measurement result is explained as shown in Figure 7.

[0332] The first device performs channel estimation (e.g., LS channel estimation) based on the first signal X(k) and the corresponding received signal Y(k) (which can refer to the received signal on the resource unit carrying the first signal in the time domain and / or the frequency domain) to obtain channel response information H(k) = Y(k) / X(k), where k = 0, 1, 2, ..., K-1 represents the resource unit index. After obtaining the channel response H(k), the first device transforms it to the first domain and determines the target sampling point (sample) in the first domain.

[0333] For example, H(f) is the channel response, where f = 0, 1, 2, ..., K-1 represents frequency domain resource units (e.g., subcarrier indices). Then, by performing an inverse Fourier transform on H(f), it can be transformed to the time delay domain (the first domain). As another example, H(f,t) is the channel response, where f = 0, 1, 2, ..., K-1 represents frequency domain resource units (e.g., subcarrier indices), and t = 0, 1, 2, ..., M-1 represents time domain resource units (e.g., OFDM symbol indices). Then, by performing an inverse Fourier transform along the frequency domain and a Fourier transform along the time domain on H(f,t), it can be transformed to the time delay domain. Switching to the time-delay-Doppler domain (first domain); for example, H(f,t,s) is the channel response, where f = 0,1,2,…,K-1 represents frequency domain sampling points (e.g., subcarrier index), t = 0,1,2,…,M-1 represents time domain sampling points (e.g., OFDM symbol index), and s = 0,1,2,…,P-1 represents spatial domain sampling points (antenna index or port index). Then, by performing inverse Fourier transform along the frequency domain, Fourier transform along the time domain, and Fourier transform along the antenna domain on H(f,t,s), it can be transformed to the time-delay-Doppler-angle domain (first domain).

[0334] In this embodiment, taking the first domain as an example of the time-delay-Doppler domain, the result obtained by transforming the channel information into the time-delay-Doppler domain is called the time-delay-Doppler spectrum.

[0335] CFAR detection is performed on the time-delay Doppler spectrum. The amplitude or power of the sampling points on the distance-Doppler spectrum that do not meet the CFAR threshold requirements are set to zero to obtain the CFAR detection results, as shown in Figure 8.

[0336] In this context, the sampling points in the time-delay-Doppler spectrum that meet the CFAR detection threshold are the target sampling points, i.e., the sampling points with non-zero amplitude or power in Figure 8. In some implementations, the amplitude or power of sampling points that do not meet the CFAR threshold are set to zero, while the amplitude or power of sampling points that meet the CFAR threshold are set to 1.

[0337] In some implementations, CFAR detection can also be performed based on the first domain filtering information, that is, CFAR detection is performed only within the Doppler range or time delay range indicated by the first domain filtering information to determine the target sampling point.

[0338] CFAR (Constant False Alarm Rate) is a commonly used threshold detection method in practical radar sensing applications. In this method, for the detection of a specific target cell in the first domain, the clutter / noise power or amplitude at the target cell is estimated based on the signal power or amplitude of several nearby reference cells (determined by the lengths of the guard and reference cells). This estimation is used to set the detection threshold for the target cell. For example, the threshold value for detecting the target cell is obtained by multiplying the clutter / noise power or amplitude by the threshold factor α. Based on the calculation method of the clutter / noise power, CFAR detection can be categorized into Cell Averaging-Constant False Alarm Rate (CA-CFAR), Greatest Option-Constant False Alarm Rate (GO-CFAR), Smallest Option-Constant False Alarm Rate (SO-CFAR), and Order Statistics-Constant False Alarm Rate (OS-CFAR), among others. Different CFAR detection types are applicable to different sensing scenarios and have varying performance. Therefore, the specific CFAR detection type can be determined based on sensing requirements or historical measurement results (such as the number of targets, at least one of the sensing performance indicators), and then indicated to the first device. Taking time-delay-Doppler two-dimensional CFAR detection as an example, the patterns of the reference cell and protection cell for a specific unit to be detected are shown in Figure 5. The same applies to one-dimensional or three-dimensional CFAR detection, and will not be elaborated further.

[0339] The threshold factor α is calculated based on the false alarm probability P. fa The number of reference elements N (as shown in Figure 8, determined based on the length of the protection element and the length of the reference element) is calculated, specifically: α = N(P fa -1 / N -1)

[0340] The reference unit length can be, as shown in Figure 5, indicating the reference unit lengths 1 and 2 on either side of the unit to be detected, or it can indicate the overall reference unit length (length 1 + length 2), or simply indicate a different length. Furthermore, for multi-dimensional CFAR detection, the protection unit and reference unit information can be indicated separately according to different dimensions, such as the protection unit and reference unit lengths indicating the time delay dimension and Doppler dimension respectively in Figure 5. Besides using a uniform rectangular pattern to determine the selection of reference and protection units as shown in Figure 5, it can also be determined based on other patterns. These can be several patterns agreed upon in the protocol, or multiple patterns can be provided to the first device in advance by the second device, and then one can be dynamically indicated according to the sensing requirements.

[0341] In some implementations, to further reduce the number of target sampling points, clustering can be performed on the results of CFAR detection. Taking the selection of target paths in the time delay domain as an example, as shown in Figure 4, the sampling points that meet the amplitude or power exceeding the preset threshold are 0, 0a, 1, 1a, and 2, as determined by CFAR detection. These are then clustered, where sampling points 0 and 0a have the same cluster label, and sampling points 1 and 1a have the same cluster label. Finally, the sampling point with the largest amplitude or power is selected from the sampling points with the same cluster label as the target sampling point, thus obtaining target sampling points 0, 1, and 2. Alternatively, sampling points with the same cluster label can be weighted and merged to obtain the target sampling point. For example, sampling points 0 and 0a can be weighted and merged according to their amplitude or power to obtain target sampling point 0', and sampling points 1 and 1a can be weighted and merged according to their amplitude or power to obtain target sampling point 1'. Finally, target sampling point 0', target sampling point 1' and target sampling point 2' (i.e. sampling point 2, because the cluster containing sampling point 2 only has one sampling point, so the sampling points in this cluster are weighted and merged to obtain target sampling point 2', which is sampling point 2)'.

[0342] Once the target sampling point in the time-delay-Doppler domain is detected, the time delay τ of target sampling point i can be determined. i or Doppler f di Therefore, the distance d from the target sampling point i can be calculated. i Or radial velocity v i Taking monostatic sensing as an example Where c represents the speed of light, f c This represents the carrier frequency. Further, based on the complex value H(f) of the channel response at target sampling point i on the time-delay-Doppler spectrum corresponding to different receiving antenna ports... di ,τ i (or phase information) can be used to calculate the angle of arrival information of the target sampling point, including the azimuth angle of arrival AoA. i And the zenith angle of arrival (zoA) iAlternatively, based on the channel response complex value H(f) of the target sampling point i on the delay-Doppler spectrum corresponding to different transmitting antenna ports or different transmitting signal resources. di ,τ i Alternatively, phase information can be used to calculate the departure angle information of the target sampling point, including the azimuth departure angle (AoD). i ZoD (Zenith Departure Angle) i .

[0343] Based on at least one of the time delay (or distance) information and angle information of target sampling point i, the position information (x, y, y) of target sampling point i is calculated. i ,y i ,z i The location information can be Cartesian coordinate information, including the x, y, and z values ​​corresponding to a reference point in a global or local coordinate system, and also including the units of x, y, and z (mm, cm, dm, m, etc.), such as the coordinates relative to a signal receiving or transmitting device in the global coordinate system, or the coordinates of the target relative to the origin of the coordinate system (a known reference position) in the global coordinate system. It can also be longitude, latitude, and altitude information, including absolute longitude, latitude, and altitude information, and relative longitude, latitude, and altitude information relative to a reference point. In some scenarios, the location information may only contain the x and y values ​​of Cartesian coordinates, or only contain longitude and latitude information (i.e., the location information can be either 3D or 2D).

[0344] The target sampling point position coordinate distribution is calculated based on the time-delay-Doppler spectrum, as shown in Figures 9 and 10. Figure 9 shows the information of the target sampling points in the time-delay-Doppler spectral domain, and Figure 10 shows the information of the target sampling points in the three-dimensional coordinate domain.

[0345] As shown in Figures 9 and 10, in the time-delay-Doppler spectrum, the Doppler values ​​corresponding to different target sampling points may be different, but their corresponding time delay values ​​or angle values ​​may be similar, thus their three-dimensional coordinates are similar. In fact, these target sampling points are associated with the same sensing target. Due to spectrum leakage or missing channel sampling information, spurious peaks appear, resulting in different target sampling points associated with the same sensing target during detection. The target sampling points can be further merged or filtered by clustering according to their position coordinates to obtain the final sensing result. For example, clustering can be performed based on the position coordinates of each target sampling point; targets with similar position coordinates have the same cluster label. Finally, the coordinates of the target sampling point with the largest amplitude or power among the sampling points with the same cluster label are selected as the position coordinates of the sensing target. Alternatively, sampling points with the same cluster label can be weighted and merged according to their amplitude or power to obtain the position coordinates of the sensing target. It is important to note that the Doppler values ​​of sampling points associated with the same target may differ significantly. The Doppler value of the target sampling point with the highest power or amplitude is usually close to the true Doppler value of the target being sensed (i.e., the Doppler value of the main peak associated with the target being sensed; it is generally believed that the power of the pseudo-peak caused by spectrum leakage or missing channel sampling information is less than that of the main peak). In other words, the calculation of the Doppler or radial velocity of the target being sensed can be directly based on the Doppler value or radial velocity of the target sampling point with the highest power or amplitude among the target sampling points with the same cluster label after clustering.

[0346] Example 3:

[0347] This embodiment mainly describes the reporting format of measurement results.

[0348] As described in Embodiment 2, if the first device does not perform the calculation from the measurement result to the perception result, including clustering processing and further calculation processing based on the information of the target sampling point to obtain the perception result, the first device will report the measurement result, i.e. the information of the target sampling point, to the second device, and the second device or other devices (the second device may forward the measurement result to other devices) will calculate the perception result.

[0349] Taking the measurement information of the target sampling point as the location coordinates of the target sampling point as an example, the measurement information of the target sampling point can generally also be called point cloud information. One approach is that the first device, while reporting the point cloud information, also reports the measurement indicators associated with the target sampling point, including at least one of the following: received power indicator, signal-to-interference-plus-noise ratio (SINR), signal-to-noise ratio (SNR), or signal-to-clutter ratio (SCR). A sensing result calculation device, such as a second device or other device, calculates the sensing result based on the point cloud information and the measurement indicators associated with the target sampling point; see Embodiment Two for details.

[0350] Alternatively, as described in the second embodiment, after directly performing clustering processing on the point cloud information, the final sensing result can be calculated according to the measurement information of the target sampling point with the largest amplitude or power (that is, the largest measurement index value) among the target sampling points with the same cluster label. Therefore, the sensing result calculation device does not need to obtain the measurement indexes of all target sampling points, and only needs to know which target sampling point has the largest measurement index value among the target sampling points with the same cluster label. Therefore, when the first device reports the point cloud information, the reporting format is that the sampling point information is sorted in ascending or descending order according to the measurement index associated with each target sampling point and then reported.

[0351] Exemplarily, the format of the measurement result reported by the first device is: {number of target sampling points N; (x0,y0,z0), (x1,y1,z1), ..., (x N-1 ,y N-1 ,z N-1 )};

[0352] If the information of the target sampling point further includes Doppler information, the format of the measurement result reported by the first device may be: {number of target sampling points N; (x0,y0,z0), (x1,y1,z1), ..., (x N-1 ,y N-1 ,z N-1 ); f d0 , f d1 , ..., f dN-1}; or: {number of target sampling points N; {(x0,y0,z0), f d0}, {(x1,y1,z1), f d1}, ..., {(x N-1 ,y N-1 ,z N-1 ), f dN-1}}.

[0353] Wherein, for any target sampling point n1 and target sampling point n2, 0≤n1<n2≤N-1 are the indexes or serial numbers of the sampling points, and the measurement index I1 of sampling point n1 and the measurement index I2 of sampling point n2 satisfy I1≥I2 or I1≤I2.

[0354] In this way, after the sensing result calculation device (such as the second device) receives the measurement result reported by the first device, assuming that the measurement result is {number of target sampling points N; {(x0,y0,z0), f d0}, {(x1,y1,z1), f d1}, ..., {(x N-1 ,y N-1 ,z N-1 ), f dN-1}, wherein for any target sampling point n1 and target sampling point n2, 0≤n1<n2≤N-1 are indices or serial numbers of the sampling points, and the measurement index I1 of sampling point n1 and the measurement index I2 of sampling point n2 satisfy I1≥I2. Clustering processing is performed according to the position coordinates of N sampling points, for example, if the clustering labels of sampling point 0, sampling point 2 and sampling point 3 are the same, that is, they are determined to be associated with the same sensing target, then the information of the sampling point with the highest sorting is used as the sensing result of the sensing target, that is, the position coordinate of the sensing target is (x0,y0,z0), and the Doppler of the sensing target is f d0 .

[0355] In some embodiments, the reporting of the measurement result by the first device to the second device further includes reporting auxiliary information associated with the measurement result, which includes at least one of the following:

[0356] Timestamp information;

[0357] Precision information, including time delay precision information or distance precision information;

[0358] LOS / Non Line of Sight (NLOS) indication: whether it is LOS or NLOS between the first device and the third device (may be LOS / NLOS probability information), wherein the third device is a device that transmits a signal to the first device, that is, the first device measures the signal transmitted by the third device;

[0359] Position information of the first device, for example Cartesian coordinates relative to a known reference point (x Rx , y Rx , z Rx ), in some embodiments, the position information of the first device may refer to position information of antenna reference points of the first device;

[0360] Motion information of the first device, including at least one of whether the device is stationary, the magnitude of the motion speed of the first device, and the motion direction of the first device;

[0361] Transformation relation information between the local coordinate system and the global coordinate system of the first device (for example, when the position coordinates of the sampling points in the measurement result are position coordinates in the local coordinate system, the first device also needs to report the coordinate system transformation relation information), which includes at least one of the following: rotation angle α around the z-axis, rotation angle β around the y-axis, and rotation angle γ around the x-axis between LCS and the Global Coordinate System (GCS).

[0362] Embodiment 4:

[0363] This embodiment provides a detailed explanation of the definition and calculation of the measurement index, which includes at least one of the following:

[0364] Indicators related to received power or signal strength:

[0365] Reference signal received power at a sampling point: The linear average of the channel response power corresponding to the i-th sampling point in the first domain on the target resource carrying the first signal. To ensure fair comparison of the reference signal received power at sampling points under different signal configurations, the linear average value is preferred.

[0371] In some implementations, it can also be defined as: the total power of the channel response corresponding to the i-th sampling point in the first domain on the target resource carrying the first signal, divided by the total power of noise and interference.

[0372] Signal-to-noise ratio at sampling point: the linear average power of the channel response corresponding to the i-th sampling point in the first domain on the target resource carrying the first signal, divided by the linear average power of the noise.

[0373] In some implementations, it can also be defined as: the total power of the channel response corresponding to the i-th sampling point in the first domain divided by the total power of the noise on the target resource carrying the first signal.

[0374] Indicators related to signal-to-clutter ratio:

[0375] Signal-to-clutter ratio at a sampling point: the linear average power of the channel response corresponding to the i-th sampling point in the first domain on the target resource carrying the first signal, divided by the linear average power of clutter.

[0376] In some implementations, it can also be defined as: the total power of the channel response corresponding to the i-th sampling point in the first domain divided by the total clutter power on the target resource carrying the first signal.

[0377] In the first domain, the sampling point corresponding to clutter can be defined as any other sampling point in the first domain besides the target sampling point, or the sampling point corresponding to clutter can be defined as a sampling point within the clutter suppression region in the first domain.

[0378] The target resource can be a time-domain and / or frequency-domain resource unit carrying the first signal; the first signal can be a sensing signal, such as a dedicated signal used for sensing services, or a communication signal, such as a reference signal, a synchronization signal, etc.

[0379] For Frequency Range 1, the reference point for the measurement index should be the antenna connector of the first device (e.g., UE). For Frequency Range 2, the measurement index can be obtained by measuring the first signal based on the antenna element combination corresponding to a given receive branch (or receive channel).

[0380] If the first signal receiving device adopts receive diversity technology, the above-mentioned measurement indicators shall not be lower than the measurement indicators corresponding to any independent receiving branch; or the above-mentioned measurement indicators include the measurement indicators corresponding to multiple independent receiving branches.

[0381] Example 5:

[0382] This embodiment further explains the angle information in the measurement results. In some implementations, the first device does not calculate the position coordinates of the target sampling point, but reports the time delay or angle information of the target sampling point. The angle information includes arrival angle information or departure angle information.

[0383] The angle of arrival information includes the azimuth angle of arrival (AoA) of the target sampling point. i Or zenith angle of arrival (pitch angle of arrival) ZoA i The departure angle information includes the azimuth departure angle (AoD) of the target sampling point. i Or zenith departure angle (pitch departure angle) ZoD i Alternatively, the first device may be unable to calculate the specific AoD. i or ZoD i For example, if the first device lacks antenna configuration information for the first signal transmitting device, then the aforementioned departure angle information is used to calculate the departure angle. In this case, the departure angle information includes at least one of the following:

[0384] Phase information, or phase difference information, of a target sampling point associated with at least one port or signal resource;

[0385] Amplitude information of a target sampling point associated with at least one port or signal resource;

[0386] At least one port or signal resource is associated with precoding information, such as a Precoding Matrix Indicator (PMI). This precoding information includes precoding information associated with a target sampling point. The precoding information associated with the target sampling point refers to the index identifier of the precoding vector that best matches the target sampling point (e.g., maximizes the measurement index value of the target sampling point) obtained by the first device through traversing all or part of the precoding matrix. The precoding information also includes oversampling information. Specifically, when the first device traverses and searches for the precoding vector that maximizes the measurement index value of the target sampling point, in addition to using the default oversampling factor to generate the precoding vector, it can also use a further refined oversampling factor to generate the precoding vector, thereby obtaining a better precoding vector search result and more accurate departure angle information. Specifically, the oversampling information includes an identifier indicating whether further oversampling is performed, the actual oversampling factor used, and the enhancement factor relative to the default oversampling factor (which may be indicated to the first device by the network-side device).

[0387] Port identifiers, such as port indexes, include port identifiers associated with target sampling points, wherein the port identifier associated with the target sampling point refers to the identifier of the port with the largest value of the measurement index corresponding to the target sampling point.

[0388] Signal resource identifier, such as signal resource ID, includes signal resource identifiers associated with target sampling points, wherein the signal resource identifier associated with the target sampling point refers to the identifier of the signal resource with the largest measurement index value corresponding to the target sampling point.

[0389] For port identifiers or signal resource identifiers, different ports or signal resources use different precoding vectors, that is, different transmission beams. For example, as shown in Figure 11, resource #0 (or port #0) is the signal resource (or port) with the largest measurement index value of the target sampling point associated with the LOS path, and resource #1 (or port #1) is the signal resource (or port) with the largest measurement index value of the target sampling point associated with the sensing target reflection path.

[0390] The angle information is calculated based on the default antenna configuration. For example, if the first device does not know the specific antenna configuration of the transmitting device of the first signal, it uses the default antenna configuration, such as the horizontal and vertical antenna spacing being half a wavelength, and calculates AoD′ based on the phase information of the target sampling point or the complex value of the channel response of the target sampling point. i or ZoD′i The sensing result calculation device can calculate the actual AoD based on the actual antenna configuration information of the transmitting device of the first signal and the aforementioned information. i and ZoD i .

[0391] The antenna configuration information includes at least one of the following:

[0392] The number of antennas in the horizontal dimension;

[0393] The number of antennas in the vertical dimension;

[0394] Antenna spacing in the horizontal dimension;

[0395] Antenna spacing in the vertical dimension;

[0396] The position information of the antenna elements in the antenna array, such as the position coordinates of the antenna elements under LCS (optional, applicable to non-uniform or irregular antenna arrays);

[0397] Polarization information;

[0398] Information on the transformation relationship between the local and global coordinate systems of the antenna array.

[0399] In this embodiment of the application, when the receiving device only acquires intermediate sensing measurement results and does not perform sensing result calculations, such as when it does not support clustering or other sensing measurement result processing capabilities, the sensing measurement results are transmitted to the computing device. This can both minimize data transmission overhead and ensure that the computing device can accurately calculate the sensing results based on the sensing measurement results.
