Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art fall within the scope of protection of the present application.

It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates an "or" relationship between the associated objects before and after.
[0044] It is worth noting that the technology described in the embodiments of the present application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, and can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), or other systems.

[0045] To facilitate the understanding of the embodiments of the present application, the following technical points are introduced first:
[0046] I. Regarding communication and sensing integration
[0047] In the future, mobile communication systems such as the Beyond 5th Generation (B5G) mobile communication system or the 6th Generation (6G) mobile communication system will not only have communication capabilities but also sensing capabilities. The sensing capabilities mean that one or more devices with sensing capabilities can sense information such as the orientation, distance, and speed of target objects through the transmission and reception of wireless signals, or detect, track, identify, image, etc. target objects, events, or environments. In the future, with the deployment of small base stations with high-frequency band and large bandwidth capabilities such as millimeter waves and terahertz in the 6G network, the sensing resolution will be significantly improved compared to centimeter waves, enabling the 6G network to provide more refined sensing services. Typical sensing functions and application scenarios are shown in Table 1.
[0048]
[0049] Table 1: Typical sensing functions and application scenarios.
[0050] Communication and sensing integration (abbreviated as communication-sensing integration) means that in the same system, through spectrum sharing and hardware sharing, the integrated design of communication and sensing functions is realized. While the system is transmitting information, it can sense information such as orientation, distance, and speed, detect, track, and identify target devices or events. The communication system and the sensing system complement each other, achieving an improvement in overall performance and bringing a better service experience.
[0051] The integration of communication and radar is a typical application of communication and sensing integration (communication-sensing fusion). In the past, radar systems and communication systems were strictly separated due to different research objects and focuses, and the two systems were independently studied in most scenarios. In fact, both radar and communication systems are typical ways of information transmission, acquisition, processing, and exchange, and there are many similarities in working principles, system architectures, and frequency bands. The design of the integration of communication and radar has great feasibility, mainly reflected in the following aspects: First, both the communication system and the sensing system are based on the electromagnetic wave theory, using the emission and reception of electromagnetic waves to complete information acquisition and transmission; Second, both the communication system and the sensing system have structures such as antennas, transmitters, receivers, and signal processors, with a large overlap in hardware resources; With the development of technology, there is also an increasing overlap in their working frequency bands; In addition, there are similarities in key technologies such as signal modulation and reception detection, and waveform design. The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, spectrum efficiency improvement, mutual interference reduction, etc., thus improving the overall performance of the system.
[0052] According to the differences between the first signal sending node and the receiving node, it is divided into six basic sensing methods, as Figure 1 shown, specifically including:
[0053] (1) Base station echo sensing. In this sensing method, base station A sends the first signal and performs sensing measurement by receiving the echo of the first signal.
[0054] (2) Air interface sensing between base stations. Base station B receives the first signal sent by base station A and performs sensing measurement.
[0055] (3) Uplink air interface sensing. Base station A receives the first signal sent by terminal A and performs sensing measurement.
[0056] (4) Downlink air interface sensing. Terminal B receives the first signal sent by base station B and performs sensing measurement.
[0057] (5) Terminal echo sensing. Terminal A sends the first signal and performs sensing measurement by receiving the echo of the first signal.
[0058] (6) Sidelink (SL) sensing between terminals. Terminal B receives the first signal sent by terminal A and performs sensing measurement.

[0124] For example, if H(f) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency domain sampling points (such as subcarrier indices), then by performing the inverse Fourier transform on H(f), it can be transformed into the time 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 (such as subcarrier indices) and t = 0, 1, 2, …, M - 1 represents the time domain sampling points (such as 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 time 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 (such as subcarrier indices), t = 0, 1, 2, …, M - 1 represents the time domain sampling points (such as Orthogonal Frequency Division Multiplexing (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 time delay-Doppler-angle dimension (the first dimension).
[0125] In this application, a method for determining the paths associated with the sensing target (simply referred to as sensing paths) in the channel response measured from the first signal:
[0126] Step 1: Determine the first path set. The paths in the first path set include the paths whose amplitude or power or intensity or energy exceeds a preset threshold among all the paths after the channel response is transformed into the first dimension. (For example Figure 5 in which, paths 0, 1, 2, 3 are the paths in the first path set);
[0127] Optionally, the preset threshold can be set to be higher than the noise threshold or higher than the noise interference threshold.
[0128] It can be understood that the step of determining the first path set is optional, and the paths associated with the sensing target can also be determined only according to Step 2.
[0129] Step 2: Select the paths that meet the first condition from the first path set or from all the paths as the paths associated with the sensing target.
[0130] Optionally, the first condition includes at least one of the following:
[0131] 1) The amplitude, power, intensity, or energy of the path exceeds a preset threshold or lies within a preset range; for example, the preset threshold is 5 times the noise threshold.
[0132] 2) The Doppler of the path exceeds a preset threshold or lies within a preset range.
[0133] 3) The time delay of the path exceeds a preset threshold or lies within a preset range.
[0134] 4) The angle of the path exceeds a preset threshold or lies within a preset range.
[0135] 5) The difference in amplitude, power, intensity, or energy between the path and the first-arrival path (e.g., the Line-of-Sight (LOS) path) or the reference path (e.g., the signal path reflected by a known target (e.g., a Reconfigurable Intelligence Surface (RIS), a Backscatter device, or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range.
[0136] 6) The Doppler difference between the path and the first-arrival path (e.g., the LOS path) or the reference path (e.g., the signal path reflected by a known target (e.g., a RIS, a Backscatter device, or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range.
[0137] 7) The time-delay difference between the path and the first-arrival path (e.g., the LOS path) or the reference path (e.g., the signal path reflected by a known target (e.g., a RIS, a Backscatter device, or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range.
[0138] 8) The angle difference between the path and the first-arrival path (e.g., the LOS path) or the reference path (e.g., the signal path reflected by a known target (e.g., a RIS, a Backscatter device, or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range.
[0139] 9) 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 a Tag, a backscatter device, or a RIS, that is, the path associated with the sensed target can be the path modulated and reflected by a Tag, a backscatter device, or a RIS.
[0140] It should be noted that the above first conditions can also be based on the results of statistics over a period of time; for example, the proportion of the above indicators (such as Doppler of the path, time delay of the path, etc.) exceeding a preset threshold or falling within a preset range in a preset time window reaches a preset proportion, or the number of times the above indicators (such as Doppler of the path, time delay of the path, etc.) exceed a preset threshold or fall within a preset range in a preset time window reaches a preset number;
[0141] 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 perception prior information or perception requirements. Alternatively, the preset threshold or the set range is determined by the receiving device according to perception prior information or perception requirements.
[0142] Among them, the perception prior information or perception requirements include at least one of the following:
[0143] 1) Perception service or perception service type;
[0144] Optionally, the perception service may include but is not limited to at least one of the following: detecting whether a target exists, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category division, radar cross-section 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 or brightness or temperature or atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environment reconstruction, terrain and landform, building or vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; the perception service type may classify multiple different perception services according to certain characteristics, for example, classified into detection-type perception services (such as including 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, and may 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 or 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;
[0145] 2) Perception target area;
[0146] Optionally, the sensed target area includes the position area of the sensed object or the position area where imaging or environmental reconstruction needs to be performed; for example, a preset interval range of the time delay of the sensed target correlation path is determined according to the approximate position or distance of the sensed object.
[0147] 3) Type of sensed object;
[0148] Optionally, the sensed objects are classified according to their possible motion characteristics. Each type of sensed object contains information such as the motion speed range, motion acceleration range, and typical RCS range of typical sensed objects.
[0149] 4) Number of sensed targets;
[0150] Optionally, as a kind of sensed prior information, the camera sensing result can be used to obtain the number of sensed targets.
[0151] For example, Figure 5 The medium diameters 0, 1, 2, and 3 are the paths in the first path set. Among them, the paths 2 and 3 are the sensed paths that meet the first condition (for example, their time delays meet the preset threshold), and the paths 0 and 1 are the paths associated with other scatterers. Figure 5 The horizontal axis in the figure is the first dimension, and the vertical axis is the normalized amplitude or power or intensity or energy.
[0152] 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 cannot be lower than the metric 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 signals on multiple antenna elements corresponding to this receiving channel.
[0153] In another embodiment of the present application, the calculation method of the first metric is as follows:
[0154] Optionally, when calculating the received power of the sensed target correlation path, it can also be the difference between the power of the sensed target correlation path in the first dimension and as the first metric, where N1 represents the number of paths associated with the sensed target. is the average power of multiple paths outside the first path set in the first dimension.
[0155] In one embodiment of the present application, the calculation method of the received power of the first signal is as follows:
[0156] The received power of the first signal can be that after the receiving device obtains the channel response H(k), it transforms it to the first dimension, determines the first path set in the first dimension, and then calculates the sum of the powers of all the paths in the first path set.
[0157] In another embodiment of the present application, the calculation method of the received power of the first signal is as follows:
[0158] The received power of the first signal can also be the difference between the sum of the powers of all the paths in the first path set in the first dimension and where N2 represents the number of paths in the first path set.
[0159] Optionally, the calculation method of the total received power: the total received power
[0160] In one embodiment of the present application, the calculation method of the third indicator:
[0161] The channel response H(k) is subjected to the first filtering process to obtain H filter1 (k), and then the received signal Y filter1 after the first filtering process is calculated according to H filter1 (k) and the first signal X(k), that is, Y filter1 (k) = H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter1 (k) after the first filtering process to obtain the interference and noise signal y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then the third indicator is calculated
[0162] wherein, the first filtering process is used to eliminate the noise and interference in the first dimension and the paths not associated with the perceived target. For example, the first filtering process sets Figure 5 the amplitude or power or intensity or energy of the paths other than the paths associated with the perceived target 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.
[0163] In one embodiment of the present application, the calculation method of the fourth indicator is as follows:
[0164] The channel response H(k) is subjected to the second filtering process to obtain H filter2 (k), and then the received signal Y filter2 after the second filtering process is calculated according to Hfilter2 (k), that is, Y filter2 (k) = H filter2 (k)X(k). Then subtract the received signal Y filter2 (k) after the second filtering process from the received signal Y(k) to obtain the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 ((k), and then calculate to obtain the fourth index
[0165] The second filtering process can be a noise interference suppression process in the first dimension (for example Figure 5 setting the amplitude or power or intensity or energy of other paths except the first path set 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.
[0166] In another implementation manner of the present application, the calculation method of the fourth index is as follows:
[0167] Calculate the fourth index P according to the average power of multiple paths outside the first path set in the first dimension σ2 , that is where N represents the number of sampling points in the first dimension.
[0168] If the receiving device determines multiple 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:
[0169] Method 1: Calculate the sensing performance indexes of each sensing target respectively. For example, in Figure 5 determine the paths associated with each sensing target respectively, and then calculate the respective sensing performance indexes corresponding to each sensing target; when calculating the third index corresponding to a certain sensing target (such as sensing target A) at this time, there are two methods: that is, the third index of sensing target A = total received power - the first index of sensing target A; or, the third index of sensing target A = total received power - the first index of sensing target A - the first index of sensing target B; (assuming there are two sensing targets in total: A and B); similarly, there are also two calculation methods for the fifth index: the fifth index of sensing target A = RSRP of the first signal - the first index of sensing target A; or, the fifth index of sensing target A = RSRP of the first signal - the first index of sensing target A - the first index of sensing target B; (assuming there are two sensing targets in total: A and B).
[0170] Method 2: Calculate a sensing performance metric for multiple sensing targets. For example, in Figure 5 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 treating multiple sensing targets as a virtual sensing target, and then calculating the sensing performance metric corresponding to the virtual sensing target.
[0171] In an embodiment of the present application, the first device obtains the sensing performance metric of the first signal, including:

[0175] wherein, the first information is used to indicate the first preset threshold or the first preset interval of the sensing performance metric that requires fuzzification processing.
[0176] For example, when the sensing performance metric of the first signal is greater than or equal to the first preset threshold of the sensing performance metric, it is determined that the first device performs fuzzification processing on the first sensing measurement.
[0177] For another example, when the sensing performance metric of the first signal is within the first preset interval of the sensing performance metric, it is determined that the first device performs fuzzification processing on the first sensing measurement.
[0178] For another example, when the sensing performance metric of the first signal is outside the first preset interval of the sensing performance metric, it is determined that the first device performs fuzzification processing on the first sensing measurement.
[0179] It can be understood that in this embodiment, the specific values of the first preset threshold or the first preset interval of the sensing performance metric that requires fuzzification processing are not limited.

[0199] or,
[0200] The N-th level first perceptual measurement quantity is fuzzified to obtain the N-th level first perceptual measurement quantity after fuzzification.
[0201] In one embodiment of the present application, the fuzzification processing is associated with a perceptual performance index of the first signal. For example, the higher the perceptual performance index of the first signal, the greater the noise or error added to the first perceptual measurement during the fuzzification processing.
[0202] In one embodiment of the present application, the fuzzification process includes at least one of the following:
[0203] 1) Adding noise to the first perception measurement;
