[0068] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0069] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. 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 here, and the objects distinguished by "first" and "second" are usually of the same category, 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.
[0070] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, 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. The terms "system" and "network" in the present application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. The following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, but these technologies can also be applied to systems other than NR system applications, such as the 6th Generation (6G) communication system. th Generation, 6G) communication system.
[0071] To facilitate the understanding of the embodiments of the present application, the following technical points are introduced first:
[0072] 1. Regarding communication and sensing integration.
[0073] In the future, mobile communication systems such as Beyond 5th Generation (B5G) mobile communication systems or 6th Generation (6G) mobile communication systems will not only have communication capabilities but also sensing capabilities. The sensing capability means that one or more devices with sensing capabilities can sense information such as the orientation, distance, and speed of a target object through the transmission and reception of wireless signals, or detect, track, identify, image, etc. a target object, event, or environment. 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. A typical sensing function and application scenario are shown in Table 1.
[0074]
[0075]
[0076] Table 1: Typical sensing functions and application scenarios.
[0077] Communication and sensing integration (abbreviated as communication-sensing integration) means that in the same system, through spectrum sharing and hardware sharing, the integration 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 a target device or event. The communication system and the sensing system complement each other, achieving an improvement in overall performance and bringing a better service experience.
[0078] The integration of communication and radar belongs to typical communication-sensing integration (communication-sensing fusion) applications. In the past, radar systems and communication systems were strictly separated due to different research objects and focuses, and the two systems were studied independently 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 terms of working principles, system architectures, and frequency bands. The design of communication-radar integration has great feasibility, which is mainly reflected in the following aspects: First, both communication systems and sensing systems are based on electromagnetic wave theory, and use the transmission and reception of electromagnetic waves to complete information acquisition and transmission; Second, both communication systems and sensing systems have structures such as antennas, transmitters, receivers, and signal processors, and there is a large overlap in hardware resources; With the development of technology, there is also more and more overlap in their working frequency bands; In addition, there are similarities in key technologies such as signal modulation, 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.
[0079] According to the differences between the first signal sending node and the receiving node, it is divided into 6 basic sensing methods, as Figure 1 shown, specifically including:
[0080] (1) Base station echo sensing. In this sensing method, base station A sends the first signal and performs sensing measurements by receiving the echo of the first signal.
[0081] (2) Air interface sensing between base stations. Base station B receives the first signal sent by base station A and performs sensing measurements.
[0082] (3) Uplink air interface sensing. Base station A receives the first signal sent by terminal A and performs sensing measurements.
[0083] (4) Downlink air interface sensing. Terminal B receives the first signal sent by base station B and performs sensing measurements.
[0084] (5) Terminal echo sensing. Terminal A sends the first signal and performs sensing measurements by receiving the echo of the first signal.
[0085] (6) Sidelink (SL) sensing between terminals. Terminal B receives the first signal sent by terminal A and performs sensing measurements.
[0086] It should be noted that Figure 1 each sensing method takes a first signal sending node and a first signal receiving node as examples. In an actual system, one or more different sensing methods can be selected according to different sensing use cases and sensing requirements, and there can be one or more sending nodes and receiving nodes for each sensing method.Figure 1 The perceived targets in [the text] use people and vehicles as examples, and it is assumed that neither people nor vehicles carry or install signal receiving devices or transmitting devices. The perceived targets in the actual scenario are more diverse.
[0087] The first signal in this article includes at least one of a reference signal, a synchronization signal, a data signal, and a dedicated signal. Supporting sensing services can be achieved by receiving or transmitting the first signal. For example, sensing measurement quantities or sensing results can be obtained by receiving or transmitting the first signal. The sensing result refers to the result that meets the sensing requirements. For example: the shape of the perceived target, 2D or 3D environment reconstruction, spatial position, orientation, displacement, moving speed, acceleration; speed measurement, distance measurement, angle measurement, or imaging of the target object in radar-based sensing; the presence or absence of people or objects; actions, gestures, breathing frequency, heart rate, sleep quality, etc. of the perceived target such as people.

For example, the new signal is formed by splicing, combining, or superimposing at least one dedicated first signal or reference signal and at least one communication signal in the time domain or frequency domain.

That is, it can be a network node in the core network or RAN responsible for at least one of the functions such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. For example, it can be upgraded based on the Access and Mobility Management Function (AMF) or Location Management Function (LMF) in a 5G network, or it can be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the Sensing Function network element can include at least one of the following:

[0091] (2) Determine the sensing method to be used based on factors such as the type of sensing service, sensing service consumer information, required Quality of Service (QoS) requirement information, sensing capabilities of the wireless signal transmitting device, and sensing capabilities of the wireless signal measuring device.

[0129] The tenth index represents the first index divided by the first received power and then multiplied by a first coefficient. The first received power represents the total received power on the target resource, or the first received power represents the product of the Received Signal Strength Indication (RSSI) and a second coefficient. The measurement resource of the RSSI is the target resource or other resources, i.e., the tenth index = K2 * the first index / the total received power, where K2 is a coefficient;
[0130] Wherein, the first device includes a first base station or a distributed unit.
[0131] In an implementation manner of the present application, the obtaining method of the perceived target associated path includes:
[0132] The first device performs channel estimation on the target signal and the received signal corresponding to the target signal to obtain a channel response;

[0142] Among them, the first condition includes at least one of the following:
[0143] 1) The first parameter of the path is greater than or equal to the first threshold or within the first interval range;
[0144] 2) The difference between the parameter of the path and the parameter of the first-arrival path or the reference path is greater than or equal to the second threshold or within the second interval range;
[0145] 3) The second parameter of the path satisfies a preset modulation rule;
[0146] Among them, the first parameter includes at least one of the following: amplitude, power, intensity, energy, Doppler, time delay, angle;

[0149] The first device determines a first path set from the paths corresponding to the first dimension. The third parameter of each path in the first path set is greater than or equal to the third threshold. The third parameter includes at least one of the following: amplitude, power, intensity, energy;
[0150] The first device determines, from the first path set, the paths that meet the first condition as the perception target associated paths.
[0151] In an implementation manner of the present application, the calculation method of the first index is as follows:
[0152] The terminal performs channel estimation on the basis of the transmitted first signal (hereinafter represented by X(k)) and the received signal corresponding to the first signal (hereinafter represented by Y(h)) to obtain the channel response (Channel Response), that is, H(k) = Y(k) / X(k), where k = 0, 1, 2,..., K - 1 represents the resource unit index. After the terminal obtains the channel response H(k), it transforms it into the first dimension and determines the perception target associated paths in the first dimension. Then, the power of the perception target associated paths is calculated as the first index. If the perception target associated paths include multiple paths, the sum of the powers of the multiple paths is calculated as the first index.
[0153] Among them, the first dimension includes at least one of the following: time delay dimension; Doppler dimension; azimuth angle dimension; elevation angle dimension. For example, time delay-Doppler dimension, time delay-Doppler-angle dimension, etc.;
[0154] 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 H(f) can be transformed to the delay dimension (the first dimension) by performing an inverse Fourier transform on H(f); 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 H(f,t) can be transformed to the delay-Doppler dimension (the first dimension) by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension; for yet 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., 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 H(f,t,s) can be transformed to the delay-Doppler-angle dimension (the first dimension) by performing an inverse Fourier transform along the frequency domain dimension, a Fourier transform along the time domain dimension, and a Fourier transform along the antenna domain dimension.
[0155] In this application, a method for determining the paths associated with the sensing target in the channel response measured for the first signal (simply referred to as sensing paths):
[0156] Step 1: Determine the first path set. The paths in the first path set include the paths among all the paths whose amplitude or power or intensity or energy exceeds a preset threshold after the channel response is transformed to the first dimension. (For example Figure 11 in which, paths 0, 1, 2, 3 are the paths in the first path set);
[0157] Optionally, the preset threshold can be set to be higher than the noise threshold or higher than the noise interference threshold.
[0158] 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.
[0159] 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.
[0160] Optionally, the first condition includes at least one of the following:
[0161] 1) The amplitude or power or intensity or 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;
[0162] 2) The Doppler of the path exceeds a preset threshold or is within a preset range;
[0163] 3) The time delay of the path exceeds a preset threshold or is within a preset range;
[0164] 4) The angle of the path exceeds a preset threshold or is within a preset range;
[0165] 5) The difference in amplitude or power or 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) or a Backscatter or other known passive target, etc.)) exceeds a preset threshold or is within a preset range;
[0166] 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 or a Backscatter device or other known passive target, etc.)) exceeds a preset threshold or is within a preset range;
[0167] 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 or a Backscatter device or other known passive target, etc.)) exceeds a preset threshold or is within a preset range;
[0168] 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 or a Backscatter device or other known passive target, etc.)) exceeds a preset threshold or is within a preset range;
[0169] 9) The amplitude or 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 or 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 or a backscatter device or a RIS.
[0170] It should be noted that the first condition of each of the above items can also be based on the statistical results 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 the preset threshold or being within the 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 the preset threshold or are within the preset range reaches a preset number within the preset time window;
[0171] Among them, the preset threshold or set range is sent by other devices to the receiving device, which is determined by other devices according to the prior perception information or perception requirements. Alternatively, the preset threshold or set range is determined by the receiving device according to the prior perception information or perception requirements.
[0172] Among them, the prior perception information or perception requirements include the following information:
[0173] 1) Perception service or perception service type;
[0174] 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 classification, radar cross-section radar cross-section detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, 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, 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, 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 functions. 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 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 prior perception information;
[0175] 2) Perception target area;
[0176] Optionally, the perception target area includes the position area of the perception object, or the position area that needs to be imaged or reconstructed; for example, the preset interval range of the time delay of the perception target correlation path is determined according to the approximate position or distance of the perception object;
[0177] 3) Perception object type;
[0178] Optionally, the perception objects are classified according to the possible motion characteristics of the perception objects, and each perception object type contains information such as the motion speed range, motion acceleration range, and typical RCS range of typical perception objects;
[0179] 4) Number of perceived targets;
[0180] Optionally, as a kind of perception prior information, the camera perception result can be used to obtain the number of perceived targets.
[0181] For example, Figure 11 The medium diameters 0, 1, 2, and 3 are the diameters in the first diameter set, where the diameters 2 and 3 are the perceived diameters that meet the first condition (for example, their time delays meet the preset threshold), and the diameters 0 and 1 are the diameters associated with other scatterers. Figure 11 The horizontal axis is the first dimension, and the vertical axis is the normalized amplitude or power or intensity or energy.
[0182] 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 that receiving channel.
[0183] In another embodiment of the present application, the calculation method of the first metric is as follows:
[0184] Optionally, when calculating the received power of the perceived target associated diameter, it can also be the difference between the power of the perceived target associated diameter in the first dimension and as the first metric, where N 1 represents the number of diameters associated with the perceived target. is the average power of multiple diameters outside the first diameter set in the first dimension.
[0185] In one embodiment of the present application, the calculation method of the received power of the first signal is as follows:
[0186] 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 diameter set in the first dimension, and then calculates the sum of the powers of all diameters in the first diameter set.
[0187] In another embodiment of the present application, the calculation method of the received power of the first signal is as follows:
[0188] The received power of the first signal can also be the difference between the sum of the powers of all diameters in the first diameter set in the first dimension and where N2 Indicates the number of paths in the first path set.
[0189] Calculation method of the total received power:
[0190] Total received power
[0191] In an implementation manner of the present application, the calculation method of the third index:
[0192] The channel response H(k) is subjected to a first filtering process to obtain H filter1 (k), and then based on H filter1 (k) and the first signal X(k), the received signal Y filter1 (k) after the first filtering process is calculated, 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 index is calculated
[0193] Among them, 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 11 the amplitude or power or intensity or energy of the paths other than 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.
[0194] In an implementation manner of the present application, the calculation method of the fourth index is as follows:
[0195] 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 received signal Y filter2 (k) after the second filtering process is calculated, that is, Y filter2 (k) = H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter2 (k) after the second filtering process to obtain the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then the fourth index is calculated
[0196] The second filtering process may be a noise interference suppression process in the first dimension (for example Figure 11 setting the amplitude or power or intensity or energy of other paths except the first path set to zero), or minimum mean square error (MMSE) filtering. The channel response H filter2 (k) after the second filtering process does not contain noise and interference, but only contains the paths in the first path set.
[0197] In another embodiment of the present application, the calculation method of the fourth index is as follows:
[0198] Calculate the fourth index P based on 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.
[0199] 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:
[0200] Method 1: Calculate the target index of each sensing target respectively. For example, in Figure 11 determine the paths associated with each sensing target respectively, and then calculate the respective target indexes corresponding to each sensing target; when calculating the third index corresponding to a certain sensing target (such as sensing target A), 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)
[0201] Method 2: Calculate a target index for multiple sensing targets. For example, in Figure 11 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 target index corresponding to the virtual sensing target.
[0202] In this embodiment, the measured values of the target metrics of one or more first signals can be used by the first device to determine whether the first device participates in the sensing service, or by the second device or the third device to determine whether the first device participates in the sensing service. That is, the measured values of the target metrics of the one or more first signals can be used to select a suitable first device to participate in the sensing service, ensuring the performance of sensing.

[0210] For another example, if the first device finds that it meets the time information of the sensing service in the first information (the first device can participate in sensing during this time period), the first device determines to measure the first signal.
[0211] In an implementation manner of the present application, the one or more first signals are sent by the first device (corresponding to the single-base sensing mode of the base station), or the one or more first signals are sent by the second device (corresponding to the double-base sensing mode between base stations) or the terminal (corresponding to the uplink sensing mode). Optionally, the base station of the serving cell of the terminal can be the first device, the second device, or other base stations.
[0212] Optionally, there may be N first signals (N is an integer greater than 1). The N first signals correspond to beams in N different directions (reflected by the identifiers of different first signals, i.e., different identifiers mean different beam directions). That is, the N first signals use different shaping vectors for beamforming and can be sent in a time-division manner (i.e., one first signal is sent at each moment).
[0213] Optionally, the first signal includes at least one of the following: a dedicated signal for sensing, a sounding reference signal, a preamble, a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), and a synchronization signal.

For example, the synchronization signal includes multiple beams, and each beam is associated with a first signal.

The second information is used to indicate that the measured values of the target metrics of the at least some first signals meet the second condition or is used to indicate that the first device participates in the sensing service;
[0218] Or,
[0219] If the measured values of the target metrics of the one or more first signals do not meet the second condition, the first device sends third information to the second device or the third device. The third information is used to indicate that the measured values of the target metrics of the one or more first signals do not meet the second condition or is used to indicate that the first device does not participate in the sensing service;
[0220] Wherein, the second condition includes at least one of the following:
