[0052] For ease of understanding, some content related to the embodiments of this application is described below:

[0053] I. Integrated Sensing and Communication (ISAC).

[0054] Wireless communication and radar sensing (Communication & Sensing, C&S) have been developing in parallel, but with limited intersection. They have many commonalities in signal processing algorithms, devices, and to some extent, system architectures. In recent years, traditional radar has been evolving towards more general wireless sensing. Wireless sensing can broadly refer to retrieving information from received radio signals. For wireless sensing related to the location of a sensed target, common signal processing methods can be used to estimate dynamic parameters such as the reflection delay, angle of arrival, angle of departure, and Doppler of the target signal; for sensing the physical characteristics of a target, it can be achieved by measuring the inherent signal patterns of the device / object / activity. These two sensing methods can be respectively referred to as sensing parameter estimation and pattern recognition. In this sense, wireless sensing refers to a more general sensing technology and application using radio signals.

[0055] Communication-sensing integration can also be called communication and sensing integration. ISAC has the potential to integrate wireless sensing into mobile networks, which are here called Perceptive Mobile Networks (PMNs). Perceptive Mobile Networks can simultaneously provide communication and wireless sensing services, and due to their large broadband coverage and powerful infrastructure, are expected to become an omnipresent wireless sensing solution. Perceptive Mobile Networks can be widely applied to communication and sensing in the fields of transportation, communication, energy, precision agriculture, and security. It can also provide complementary sensing capabilities to existing sensor networks, with unique day-night operation functions and the ability to penetrate fog, leaves, and even solid objects.

[0056] And, New Radio (NR) beam management.

[0057] Currently, the idle frequency bands of mobile communication networks are decreasing day by day, and the used frequency bands are gradually trending towards higher frequencies, such as millimeter wave (mmWave) promoted by 5G NR and terahertz (THz) promoted by 6G. These frequency bands have a large amount of available resources. However, higher frequencies mean greater transmission losses, so beam management technology is used in NR. In a mobile communication network, both the base station and the User Equipment (UE) may use beamforming to form beams with a narrow lobe width. The purpose of beam management is to obtain and maintain a set of base station-terminal beam pairs available for downlink (DL) and uplink (UL) transmission / reception to improve the performance of the link. Beam management includes the following aspects: beam scanning, beam measurement, beam reporting, beam indication, and beam failure recovery.

[0058] During the downlink beam management process, beam scanning is divided into three stages: P1, P2, and P3, where:

[0059] Stage P1: The base station and the terminal scan simultaneously. The beam of the base station is wider, and the reference signal is the Synchronization Signal and PBCH block (SSB). The protocol stipulates the transmission behavior of the base station, but the behavior of the terminal is not stipulated;

[0060] Stage P2: The terminal fixes the receiving beam, and the base station performs narrow beam scanning. The reference signal is the Channel State Information Reference Signal (CSI-RS);

[0061] Stage P3: The base station fixes the transmitting beam (narrow beam), and the terminal performs narrow beam scanning. The terminal beam scanning is its own behavior, and the base station needs to cooperate to transmit with the fixed beam.

[0062] Among the above three processes, P1 must be executed, while P2 and P3 are not mandatory. Based on P1, if there are higher requirements for services, the P2 process can be executed; if the terminal capabilities are available and the base station believes that the service performance can be further improved, the P3 process can be executed. The P1 process usually only relies on SSB. Since the P3 process needs to fix the terminal transmitting beam, it is not suitable to use SSB and should use CSI-RS. The P2 process can be either based on SSB or CSI-RS.

[0063] The beam scanning of the uplink beam management is based on SRS. Similar to the downlink, it can be divided into stages U1, U2, and U3, where:

[0064] Stage U1: The base station scans the transmitting beam of the terminal to determine the optimal transmitting beam of the UE, and simultaneously scans the receiving beam of the TRP to determine the optimal receiving beam of the base station; (This process is optional)

[0065] Stage U2: The base station scans the receiving beam of the TRP to determine the optimal receiving beam under the condition that the UE transmitting beam is fixed;

[0066] Stage U3: On the premise of determining the optimal receiving beam, the base station selects the optimal UE transmitting beam by scanning the transmitting beam of the terminal;

[0067] The uplink beam management can be completed by configuring dedicated Sounding Reference Signal (SRS) resources, or based on beam reciprocity, the optimal uplink transmitting beam (direction) can be determined through the optimal downlink transmitting beam.

[0068] If the current received quality of the user control channel is lower than a certain threshold due to occlusion, the terminal side initiates a beam failure recovery process. Beam failure detection is mainly based on the SSB or CSI-RS reference signals configured by the base station side. If the terminal detects that the number of failures is greater than or equal to the maximum number of failure parameters within the duration of the failure detection timer, the beam failure recovery process is triggered. The TRP receives the uplink recovery request signal through the receiving end beam scanning. The terminal will reselect a new beam corresponding to the SSB according to the beam recovery parameter configuration and initiate a random access process on the Physical Random Access Channel (PRACH) resource for beam recovery to re-establish a new beam pair with the base station and resume transmission.

[0069] III. Sensing measurement.

[0070] In a mobile communication network, a base station (including one or more Transmission Reception Points (TRPs) on the base station) and a User Equipment (UE) (including one or more sub-arrays / panels (Panels) on the UE) can serve as sensing nodes participating in the integrated sensing / communication service. Typical UEs include mobile phone terminals, portable tablet computers, etc. By sending and receiving the first signal between nodes, it is possible to sense a certain area or an entity target. The first signal can be a signal that does not contain transmission information, such as existing LTE / NR synchronization and reference signals, including SSB, CSI-RS, Demodulation Reference Signal (DMRS), SRS, Positioning Reference Signal (PRS), Phase Tracking Reference Signal (PTRS), etc.; it can also be a single-frequency continuous wave (CW), frequency-modulated continuous wave (FMCW), and ultra-wideband Gaussian pulse commonly used in radar; it can also be a newly designed dedicated signal with good correlation characteristics and low peak-to-average power ratio, or a newly designed integrated sensing / communication signal that not only carries certain information but also has good sensing performance. For example, the new signal is formed by splicing / combining / superimposing at least one dedicated sensing signal / reference signal and at least one communication signal in the time domain or frequency domain.

[0071] According to whether the sensing nodes are the same device, two sensing methods can be divided: A transmits and B receives, and A transmits and receives by itself. A transmits and B receives means that the sensing node A and the sensing node B are not the same device and are physically separated; A transmits and receives by itself means that the first signal transmission and reception are performed by the same device, and the sensing node A senses by receiving the signal echo it sends. This patent mainly discusses the A transmits and B receives sensing method.

[0072] The node that sends or receives the first signal is called a sensing node. The node that performs indication, scheduling, control, and sensing result calculation on the sensing node can be a certain node in the sensing node or a device in the core network, such as a sensing function network element (Sensing Function, SF), an access and mobility management function (Access and Mobility Management Function, AMF), a sensing application server in the core network, etc.

[0073] Since 5G and future 6G will increasingly use high-frequency band communication, NR has introduced beam management to overcome high-frequency attenuation, enhance communication coverage, and ensure communication quality. For a base station or UE with multiple antennas, a digital channel is usually connected to multiple physical antenna elements, and the multiple physical antenna elements use analog beamforming to generate directional beams. When the prior information of the environment by the sensing node is less, or the sensing service is to sense a relatively large area, a single beam of the above hardware architecture may not be able to cover the sensing target / sensing area. If a wide beam is used to increase sensing coverage, the sensing angle resolution will decrease due to the increase in beam width. Moreover, due to the small number of ports used in beam management (SSB is a single port, and the number of CSI-RS ports is 1 or 2 (cross-polarization)), it is impossible or difficult to achieve high-precision sensing based on the principle of MIMO radar.

[0074] Therefore, this application provides a beam management for at least two ports (or multi-ports) of a sensing node, where at least two ports are mapped to physical antennas / antenna sub-arrays at different array positions for sensing; and at least one port is used for communication. Communication and sensing can share at least one port. The beam management of the multi-ports at least includes: joint communication and sensing beam scanning, joint communication and sensing beam measurement, joint communication and sensing beam reporting / indication, and joint communication and sensing beam failure recovery. Based on the measurement values of the sensing measurement quantities of not less than 1 port and the measurement values of the communication measurement quantities of at least 1 port, the optimal communication beam set of at least one port, and the optimal sensing beam sets of each port, or the optimal joint communication and sensing beam set of at least one port are obtained, so as to make full use of the array aperture to achieve high-precision sensing.

[0075] The following will combine the accompanying drawings to elaborate in detail on the perception processing method provided by the embodiments of the present application through some embodiments and their application scenarios.

[0076] Referring to Figure 2 , an embodiment of the present application provides a perception processing method. As Figure 2 shown, the perception processing method includes:

[0077] Step 201, the first device determines a first measurement result of a first measurement. The first measurement result includes a measured value of a first target metric, where the first target metric is a metric related to perception. The first measurement is a multi-port based beam measurement, and the first measurement includes at least one of the following: perception measurement; perception measurement and communication measurement; joint communication and sensing measurement;

[0078] In an embodiment of the present application, the above first measurement result may further include other measurement information. For example, it may include at least one of the following: perception measurement quantity of multi-ports; joint communication and sensing measurement quantity of multi-ports. Optionally, the other measurement information may further include a communication measurement quantity of multi-ports. The above first device may be understood as a computing node for calculating the first measurement result. The first device may specifically be a perception node or a perception functional network element, which is not further limited herein.

[0079] Optionally, the multi-port based perception measurement may be understood as that the first perception node or the second perception node performs joint communication and sensing beam scanning at at least two ports to achieve perception measurement and communication measurement, or to achieve joint communication and sensing measurement. The first perception node is the sending node of the first signal for the first measurement, and the second perception node is the receiving node of the first signal.

[0080] Step 202, the first device determines at least one of a first beam set and a second beam set based on the measured value of the first target metric. The first beam set includes at least one beam that satisfies the perception condition, and the second beam set includes at least one beam that satisfies the joint communication and sensing condition.

[0081] Optionally, after the first device determines the first measurement result, it may determine the first beam set, that is, the beam set that satisfies the perception condition, according to the above first measurement result or the measured value of the first target metric in the first measurement result. It may also determine the second beam set, that is, the beam set that satisfies the joint communication and sensing condition, according to the above first measurement result or the measured value of the first target metric in the first measurement result. It may also determine the first beam set and the second beam set.

[0082] Among them, at least one beam that meets the sensing condition can be understood as the first target index corresponding to the at least one beam, or the corresponding first target index and the sensing measurement quantity meet the sensing condition. That is, when the measured value of the sensing measurement quantity of the at least one beam or the measured value of the corresponding first target index is good, it can be used for subsequent integrated communication and sensing services. The above first beam set can be understood as the optimal sensing beam set.

[0083] At least one beam that meets the integrated communication and sensing condition can be understood as the first target index corresponding to the at least one beam, or the corresponding first target index and the integrated communication and sensing measurement quantity meet the integrated communication and sensing condition. That is, when the measured value of the integrated communication and sensing measurement quantity of the at least one beam or the measured value of the corresponding first target index is good, it can be used for subsequent integrated communication and sensing services. The above second beam set can be understood as the optimal integrated communication and sensing beam set.

[0084] It should be noted that there is an association between the beam and the sensing signal or the integrated communication and sensing signal. One beam corresponds to a configuration of a sensing signal or an integrated communication and sensing signal (including time domain, frequency domain, and antenna port configurations), or directly determines the configuration of the sensing signal or the integrated communication and sensing signal (parameter set).

[0085] In the embodiment of the present application, the first device determines the first measurement result of the first measurement. The first measurement result includes the measured value of the first target index, the first target index is a sensing-related index, the first measurement is a beam measurement based on multiple ports, and the first measurement includes at least one of the following: sensing measurement; sensing measurement and communication measurement; integrated communication and sensing measurement; the first device determines at least one of the first beam set and the second beam set based on the measured value of the first target index. The first beam set includes at least one beam that meets the sensing condition, and the second beam set includes at least one beam that meets the integrated communication and sensing condition. Since the first measurement is performed on multiple ports, the number of ports for beam management is increased. Therefore, through multi-port beamforming, the principle of virtual aperture in MIMO radar can be utilized, and through multi-port signal processing, the resolution of angle measurement can be improved. Therefore, the embodiment of the present application improves the accuracy of sensing. At the same time, the mutual superposition of multiple port signals can improve the sensing signal-to-noise ratio (SNR) and overcome the problem of limited coverage of high-frequency sensing.

[0087] The arithmetic mean of the second target indices of multiple ports;

[0088] The second target index obtained by parameter estimation based on multiple ports.

[0089] In the embodiments of the present application, parameter estimation can be performed based on each port to obtain the second target metric for each port, and then the arithmetic mean of the second target metrics of multiple ports is used as the first target metric. Alternatively, the second target metric obtained by parameter estimation based on multiple ports can be used, and in this case, the calculated second target metric can be understood as the first target metric. Since the definition of the first target metric is clear, the difficulty of terminal sensing measurement or communication-sensing joint measurement is simplified.

[0090] Optionally, in some embodiments, the second target metric includes at least one of the following: a metric related to received power; a metric related to interference and noise power; a metric related to both received power and interference or noise power.

[0091] In the embodiments of the present application, the metric related to both received power and interference or noise power can be understood to include at least one of the following: a metric related to both received power and interference; a metric related to both received power and noise power; a metric related to received power, interference, and noise power.

[0092] Optionally, in some embodiments, the metric related to received power includes: a first metric, which is used to represent the linear average of a first power on a first resource, and the first power is the received power of the path associated with the sensing target in the channel response measured for a first signal.

[0093] In the embodiments of the present application, the above first metric can be connected as the received power of the path associated with the sensing target. The above linear average can be understood as the arithmetic mean of linear values.

[0094] Optionally, the above first resource is a resource unit carrying the first signal, and this resource unit can include at least one of a time-domain resource unit and a frequency-domain resource unit. The above first signal can be a dedicated signal or a communication signal for sensing services, such as a reference signal or a synchronization signal, etc.

[0095] Optionally, the above metrics related to interference and noise power include at least one of the following:

[0096] A second metric, which is the sum of a second power and a third power. The second power represents the linear average of the power of a target path, and the target path is the other path except the path associated with the sensing target in the channel response of the first signal on the first resource. The third power represents the linear average of the interference and noise power from a second signal on the first resource or a second resource;

[0097] A third metric, which represents the linear average of the interference and noise power from a second signal on the first resource or a second resource;

[0098] The fourth indicator, where the fourth indicator is the linear average of the power of the target diameter;

[0099] Wherein, the first signal is used for the first measurement, the first resource is a resource unit carrying the first signal, and the second resource is a resource other than the first resource.

[0100] Optionally, the above-mentioned second resource may be a resource configured by high-layer signaling. The above-mentioned RSSI definition is the same as that in 3GPP TS 38.215.

[0101] Optionally, the total received power on the first resource may include the received power of signals from the serving cell and non-serving cells, adjacent channel interference, thermal noise, etc. The above-mentioned second indicator may be equal to the fourth power minus the first indicator, and the fourth power represents the total received power on the first resource. In some embodiments, the fourth power may be equal to RSSI * K1, where K1 is a coefficient.

[0102] Optionally, the above-mentioned third indicator may be equal to the fourth power minus the received power of the first signal, and the received power of the first signal may be understood as the Reference Signal Receiving Power (RSRP) of the first signal.

[0103] Optionally, the above-mentioned fourth indicator may be equal to the RSRP of the first signal minus the first indicator.

[0104] Optionally, in some embodiments, the indicators related to both the received power and the interference or noise power include at least one of the following:

[0105] The fifth indicator, where the fifth indicator is the first indicator divided by the second indicator;

[0106] The sixth indicator, where the sixth indicator is the first indicator divided by the third indicator;

[0108] The eighth indicator, where the eighth indicator is the product of the first indicator and the target coefficient divided by the fourth power, and the fourth power is the total received power on the first resource.

[0109] In the embodiments of the present application, the fifth index, the sixth index, and the seventh index can be understood as three different perceived signal-to-interference plus noise ratios (SINRs), perceived SNRs, or perceived signal-to-interference ratios (SIRs). The above-mentioned eighth index can be understood as the perceived reference signal receiving quality (RSRQ).

[0110] Optionally, in some embodiments, the calculation method of the first index is as follows:

[0111] The terminal performs channel estimation based on the transmitted first signal X(k) and the received signal Y(k) corresponding to the first signal to obtain the channel response H(k) = Y(k) / X(k), where k = 0, 1, 2,..., K - 1, representing the resource unit index. After the terminal obtains the channel response X(k), it transforms it to the first dimension and determines the perceived target associated path in the first dimension. Then, the power of the perceived target associated path is calculated as the first index. If the perceived target associated path includes multiple paths, the sum of the powers of the multiple paths is calculated as the first index.

[0112] Wherein, the first dimension includes one of the following: delay dimension; Doppler dimension; azimuth angle dimension; elevation angle dimension; a dimension jointly composed of at least two of the delay dimension, Doppler dimension, azimuth angle dimension, and elevation angle dimension, for example, delay-Doppler dimension, delay-Doppler-angle dimension, etc.

[0113] For example, if H(f) is the channel response, where f = 0, 1, 2, ..., N - 1 represents the frequency-domain sampling points (e.g., subcarrier indices), then by performing the inverse Fourier transform on H(f), it can be transformed into the delay dimension (the first dimension); for another example, if H(f, t) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency-domain sampling points (e.g., subcarrier indices), and t = 0, 1, 2, …, M - 1 represents the time-domain sampling points (e.g., OFDM symbol indices), then by performing the inverse Fourier transform along the frequency domain dimension and the Fourier transform along the time domain dimension on H(f, t), it can be transformed into the delay-Doppler dimension (the first dimension); for another example, if H(f, t, s) is the channel response, where f = 0, 1, 2, ..., N - 1 represents the frequency-domain sampling points (e.g., subcarrier indices), t = 0, 1, 2, ..., M - 1 represents the time-domain sampling points (e.g., OFDM symbol indices), and s = 0, 1, 2, ..., P - 1 represents the spatial domain sampling points (antenna indices or port indices), then by performing the inverse Fourier transform along the frequency domain dimension, the Fourier transform along the time domain dimension, and the Fourier transform along the antenna domain dimension on H(f, t, s), it can be transformed into the delay-Doppler-angle dimension (the first dimension).

[0114] The method for determining the path associated with the sensing target (simply referred to as the sensing path) in the channel response measured for the first signal is as follows:

[0115] Determine the first path set. The paths in the first path set include the paths whose amplitude / power / intensity / energy in all paths exceed a certain threshold after the channel response is transformed into the first dimension. (For example Figure 3 in which, paths 0, 1, 2, 3 are the paths in the first path set); the certain threshold can be set to be higher than the noise threshold or higher than the noise interference threshold. Among them, in Figure 3 the horizontal axis is the first dimension and the vertical axis is the normalized amplitude / power / intensity / energy. It should be understood that this step (determining the first path set) is optional, and the paths associated with the sensing target can be determined only according to the next step.

[0116] Select the paths that meet the target conditions from the first path set or from all paths as the paths associated with the sensing target.

[0117] The target conditions include at least one of the following:

[0118] The amplitude / power / intensity / energy of the path exceeds a preset threshold or is within a preset interval range; for example, the preset threshold is 5 times higher than the noise threshold

[0119] The Doppler of the path exceeds a preset threshold or is within a preset interval range

[0120] The delay of the path exceeds a preset threshold or is within a preset interval range

[0121] The angle of the path exceeds a preset threshold or lies within a preset range.

[0122] The difference in amplitude / power / intensity / energy between the path and the first-arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target such as a Reconfigurable Intelligent Surface (RIS) / Backscatter device / other known passive target, etc.) exceeds a preset threshold or lies within a preset range.

[0123] The Doppler difference between the path and the first-arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target such as a RIS / Backscatter device / other known passive target, etc.) exceeds a preset threshold or lies within a preset range.

[0124] The time-delay difference between the path and the first-arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target such as a RIS / Backscatter device / other known passive target, etc.) exceeds a preset threshold or lies within a preset range.

[0125] The angle difference between the path and the first-arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target such as a RIS / Backscatter device / other known passive target, etc.) exceeds a preset threshold or lies within a preset range.

[0126] The amplitude / power / intensity / energy or phase of the path satisfies a specific modulation rule, and the specific modulation rule is the modulation rule of the Tag / Backscatter device / RIS, that is, the path associated with the sensed target can be the path modulated and reflected by the Tag / Backscatter device / RIS.

[0127] It should be understood that the above target conditions can also be based on the results of statistics over a period of time; for example, the proportion of the above indicators (e.g., the Doppler of the path, the time delay of the path, etc.) exceeding a preset threshold or lying within a preset range reaches a preset proportion within a preset time window, or the number of times the above indicators (e.g., the Doppler of the path, the time delay of the path, etc.) exceed a preset threshold or lie within a preset range reaches a preset number within a preset time window.

[0128] Among them, the preset threshold or the set range is sent by other devices to the receiving device and determined by other devices according to the sensing prior information or sensing requirements. Or, the preset threshold or the set range is determined by the receiving device according to the sensing prior information or sensing requirements.

[0129] Among them, the sensing prior information or sensing requirements include the following information:

[0130] Perception service or perception service type. The perception service can be, for example, detecting the presence of a target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, radar cross section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading, gait recognition, expression recognition, face recognition, breathing monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environment reconstruction, terrain and landform, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density / vehicle density detection, etc.; The perception service type can classify multiple different perception services according to certain characteristics. For example, it can be classified into detection-type perception services (such as intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (action recognition, identity recognition), etc. according to function. It can also be classified according to the perception range (close-range perception, medium-range perception, long-range perception), according to the perception fineness (coarse-grained perception, fine-grained perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc. If the perception service is breathing monitoring, the corresponding normal breathing frequency can be judged according to the gender and age of a person (for example, male: 13 - 21 times per minute, female: 15 - 20 times per minute; adult: 12 - 20 times per minute, child: about 30 - 40 times per minute), which can be used as perception prior information;

[0131] Perception target area: It refers to the position area of the perception object, or the position area where imaging or environment reconstruction needs to be performed; for example, determine the preset interval range of the time delay of the perception target association path according to the approximate position / distance of the perception object;

[0132] Perception object type: Classify the perception objects according to the possible motion characteristics of the perception objects. Each perception object type contains information such as the motion speed range, motion acceleration range, and typical RCS range of typical perception objects;

[0133] The number of perception targets; for example, as a kind of perception prior information, the perception result of a camera can obtain the number of perception targets.

[0134] For example Figure 3 In it, paths 0, 1, 2, 3 are paths in the first path set, where paths 2 and 3 are perception paths that meet the target conditions (for example, their time delays meet the preset threshold), and paths 0 and 1 are paths associated with other scatterers.

[0135] For frequency range 1, the reference point of 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 shall not be lower than that of any single receiving channel. For frequency range 2, the first metric measured by a certain receiving channel needs to be obtained by measuring the combined signal on multiple antenna elements corresponding to that receiving channel.

[0136] Another optional calculation method for the first metric is as follows:

[0137] When calculating the received power of the path associated with the sensing target, it can also be the difference between the power of the path associated with the sensing target in the first dimension and N 1 P σ avr as the first metric, where N 1 represents the number of paths associated with the sensing target. N 1 P σ avr is the average power of multiple paths outside the first path set in the first dimension.

[0138] The calculation method for the received power of the first signal is as follows:

[0139] The received power of the first signal can be that after the receiving device obtains the channel response H(k), it transforms it into the first dimension, determines the first path set in the first dimension, and then calculates the sum of the powers of all paths in the first path set.

[0140] Another optional calculation method for the received power of the first signal is as follows:

[0141] The received power of the first signal can also be the difference between the sum of the powers of all paths in the first path set in the first dimension and N 2 P σ avr where N 2 represents the number of paths in the first path set.

[0142] The calculation method for the total received power:

[0143] Total received power

[0144] Optionally, the calculation method for the second metric is as follows:

[0145] After the channel response H(k) undergoes the first filtering process to obtain H filter1 (k), and then according to Hfilter1 (k) and the first signal X(k) are used to calculate the first filtered received signal Y filter1 (k), that is, Y filter1 (k) = H filter1 (k)X(k). Then, the received signal Y(k) is subtracted from the first filtered received signal Y filter1 (k) to obtain the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then a second metric is calculated

[0146] Among them, the first filtering process is used to eliminate noise and interference in the first dimension and the paths not associated with the perceived target. For example, the first filtering process sets Figure 3 the amplitude / power / intensity / energy of other paths except the paths associated with the perceived target in to zero. The channel response H filter1 (k) after the first filtering process does not contain noise and interference and the paths not associated with the perceived target, and only contains the paths associated with the perceived target.

[0147] Optionally, the third metric is calculated as follows:

[0148] The channel response H(k) is subjected to a second filtering process to obtain H filter2 (k), and then, based on H filter2 (k) and the first signal X(k), the second filtered received signal Y filter2 (k) is calculated, that is, Y filter2 (k) = H filter2 (k)X(k). Then, the received signal Y(k) is subtracted from the second filtered received signal Y filter2 (k) to obtain the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then the third metric is calculated

[0149] The second filtering process can be a noise interference suppression process in the first dimension (for example Figure 3 setting the amplitude / power / intensity / energy of other paths except the first path set in to zero), or a minimum mean square error MMSE filter. The channel response H filter2 (k) after the second filtering process does not contain noise and interference, and only contains the paths in the first path set.

[0150] Another optional calculation method for the third metric:

[0151] According to the average power of multiple paths outside the first path set in the first dimension The third metric P is calculated σ2 , that is where N represents the number of sampling points in the first dimension.

[0152] It should be understood that if the receiving device determines multiple first sensing targets, or the receiving device obtains the number of sensing targets according to sensing prior information or sensing requirements, there are the following several methods:

[0153] Method 1: Calculate the first target metric for each sensing target respectively. For example, in Figure 3 , determine the paths associated with each sensing target respectively, and then calculate each first target metric corresponding to each sensing target; when calculating the second metric corresponding to a certain sensing target (such as sensing target A) at this time, there are two methods: that is, the second metric of sensing target A is equal to the fourth power minus the first metric of sensing target A; or, the second metric of sensing target A is equal to the fourth power minus the first metric of sensing target A minus the first metric of sensing target B; (assuming there are two sensing targets in total: A and B); similarly, there are also two calculation methods for the fourth metric: the fourth metric of sensing target A is equal to the RSRP of the first signal minus the first metric of sensing target A; or, the fourth metric of sensing target A is equal to the RSRP of the first signal minus the first metric of sensing target A minus the first metric of sensing target B; (assuming there are two sensing targets in total: A and B).

[0154] Method 2: Calculate a first target metric for multiple sensing targets. For example, in Figure 3 , determine the paths associated with any sensing target, and then use these paths as the paths associated with the sensing target; it is equivalent to regarding multiple sensing targets as a virtual sensing target, and then calculating the first target metric corresponding to this virtual sensing target.

[0155] Optionally, in some embodiments, before the first device determines the first measurement result of the first measurement, the method further includes:
