[0036] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. 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.

[0037] 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 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.

[0038] It should be noted that the technology described in the embodiments of this 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 this 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.

[0039] To facilitate the understanding of the embodiments of this application, the following technical points are introduced first:

[0040] I. Regarding communication and sensing integration.

[0041] Typical sensing functions and application scenarios are shown in Table 1.

[0042]

[0043] Table 1: Typical sensing functions and application scenarios.

[0044] 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 direction, 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.

[0045] 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 of attention, 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 and 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 an increasing 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.

[0046] 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:

[0047] (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.

[0048] (2) Air interface sensing between base stations. Base station B receives the first signal sent by base station A and performs sensing measurements.

[0049] (3) Uplink air interface sensing. Base station A receives the first signal sent by terminal A and performs sensing measurements.

[0050] (4) Downlink air interface sensing. Terminal B receives the first signal sent by base station B and performs sensing measurements.

[0051] (5) Terminal echo sensing. Terminal A sends the first signal and performs sensing measurements by receiving the echo of the first signal.

[0052] (6) Sidelink (SL) sensing between terminals. Terminal B receives the first signal sent by terminal A and performs sensing measurements.

[0053] 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 perception targets in [the context] take people and vehicles as examples, and it is assumed that neither people nor vehicles carry or install signal receiving or transmitting devices. The perception targets in the actual scenario are more diverse.

[0054] Receiving or transmitting the first signal can support perception services. For example, by receiving or transmitting the first signal, perception measurement quantities or perception results can be obtained. The perception result refers to the result that meets the perception requirements. For example: the shape of the perception 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 perception; the presence or absence of people or objects; actions, gestures, breathing frequency, heart rate, sleep quality, etc. of perception targets such as people.

[0055] The first signal or the second signal in this application can be a signal that does not contain transmission information. For example, existing LTE or New Radio (NR) synchronization and reference signals, including synchronization signals and Physical Broadcast Channel (PBCH) block (SSB) signals, Channel State Information - Reference Signal (CSI - RS), Demodulation Reference Signal (DMRS), Sounding Reference Signal (SRS), Positioning Reference Signal (PRS), Phase Tracking Reference Signal (PTRS), etc.; it can also be the single - frequency continuous wave (CW), frequency - modulated continuous wave (FMCW) commonly used in radar, as well as ultra - wideband Gaussian pulses, etc.; 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 communication and sensing signal that not only carries certain information but also has good sensing performance. For example, the dedicated signal is formed by splicing, combining, or superimposing at least one dedicated first signal or dedicated second signal or reference signal and at least one communication signal in the time domain or frequency domain.

[0056] The Sensing Function network element in this application, which can also be referred to as a sensing network element or sensing function, can be on the Radio Access Network (RAN) side or the core network side. The Sensing Function network element can include radio access network devices or core network devices. The Sensing Function network element can be a network node in the core network or RAN that has 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 the 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:

[0057] (1) Perform target information interaction with a wireless signal transmitting device or a wireless signal measuring device (including the target terminal or the serving base station of the target terminal or the base station associated with the target area), where the target information includes a sensing processing request, sensing capabilities, sensing auxiliary data, sensing measurement type, sensing resource configuration information, etc., to obtain the value of the target sensing result or sensing measurement (uplink measurement or downlink measurement) sent by the wireless signal measuring device; where the wireless signal can also be the first signal.

[0058] (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. The sensing method can include: base station A transmits and base station B receives, or base station transmits and terminal receives, or base station A transmits and receives by itself, or terminal transmits and base station receives, or terminal transmits and receives by itself, or terminal A transmits and terminal B receives, etc.

[0059] (3) Determine the sensing device for the sensing service based on factors such as the type of sensing service, information of the sensing service consumer, required sensing QoS requirement information, sensing capabilities of the wireless signal transmitting device, and sensing capabilities of the wireless signal measuring device, where the sensing device includes a wireless signal transmitting device or a wireless signal measuring device.

[0060] (4) Manage the overall coordination and scheduling of resources required for the sensing service, such as making corresponding configurations for the sensing resources of the base station or terminal;

[0061] (5) Process the value of the sensing measurement, or perform calculations to obtain the sensing result. Further, verify the sensing result, estimate the sensing accuracy, etc.

[0062] The terminal in this application can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) or virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted device (VUE), a pedestrian terminal (PUE), a smart home (home devices with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, game consoles, etc. It should be noted that the specific type of the terminal is not limited in the embodiments of this application.

[0063] The core network devices in this application may include, but are not limited to, at least one of the following: core network nodes, core network functions, Mobility Management Entity (MME), AMF, LMF, Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0064] II. Regarding the Control Resource Set (CORESET) and the Search Space (SS).

[0065] CORESET is a set of time-domain and frequency-domain resources for control information. CORESET #0 is a special CORESET, which is usually used to schedule the transmission of PDCCH for System Information Block (SIB) 1. The configuration information of CORESET #0 and the configuration information of the monitoring occasion of Type0-Type0 (Type0)-PDCCH Common Search Space (CSS) are carried by the associated Cell Defining SSB (CD-SSB). The main function of CORESET #0 is to define the time and frequency resources of Type0-PDCCH CSS and the size of the monitoring occasion of Type0-PDCCH CSS.

[0066] There are two types of search space sets: one is the Common Search Space set (CSS set) jointly monitored by a group of terminals (such as User Equipment (UE)) in the cell, and the other is the UE-special Search Space (USS) set monitored by a single UE. The search space set further configures the PDCCH candidates that the UE needs to monitor. There are the following categories of search spaces in NR in total:

[0067] 1) Type0-PDCCH Common Search Space set (CSS set), used to monitor SIB1 system messages.

[0068] 2) Type0A-PDCCH CSS set, used to monitor system messages other than SIB1.

[0069] 3) Type1-PDCCH CSS set, used to monitor: a) the PDCCH corresponding to Message 2 or Message 4 in the traditional four-step random access process; b) the PDCCH corresponding to Message B in the newly added two-step random access process in the related technology.

[0070] 4) Type2-PDCCH CSS set, used to monitor paging messages.

[0071] 5) Type3-PDCCH CSS set, used to monitor the PDCCH for uplink power control, the pre-emption PDCCH, the slot format indication PDCCH, and the PDCCH related to downlink data transmission.

[0072] 6) USS set, which is used to monitor the PDCCH related to downlink data transmission.

[0073] CORESET solves the problem of the existence scope of the PDCCH, such as frequency domain and time domain resources. However, from the Radio Resource Control (RRC) signaling, it can be seen that the configuration of CORESET does not indicate the specific time domain position for the UE to monitor the PDCCH (only the time domain resources are given, that is, in the time domain, the duration length (number of symbols) of CORESET), and the specific time domain position for the UE to monitor the PDCCH is given by the monitoring occasion (MO) provided by the search space. Such a design can achieve greater flexibility. CORESET can be configured at any frequency domain position (the configuration parameter frequency domain resource information element (FrequencyDomainResources IE) is a bitmap of the physical resource block (PRB) numbers of the current bandwidth part (BWP)). The search space solves the problem of how the UE searches.

[0074] III. Regarding the types of PDCCH.

[0075] The PDCCH is the only downlink control channel in NR, and the data carried by the PDCCH is the downlink control information (DCI). DCI mainly includes the transmission resource scheduling information of the Physical Downlink Shared Channel (PDSCH) or the Physical Uplink Shared Channel (PUSCH), and in addition, there are uplink power control indications, time slot format indications, which PRBs and orthogonal frequency-division multiplexing (OFDM) symbols of the UE do not map data, etc. After a series of processes such as scrambling, modulation, and coding, DCI will be mapped to the physical resources in units of control channel elements (CCEs).

[0076] The types of PDCCH are mainly divided into three categories: common PDCCH (Common PDCCH), group common PDCCH (Group Common PDCCH), and UE-specific PDCCH (UE-Specific PDCCH).

[0077] The following will, in conjunction with the accompanying drawings, explain in detail the perception processing method, apparatus, communication device, and readable storage medium provided by the embodiments of the present application through some embodiments and their application scenarios.

[0078] See Figure 2 , an embodiment of the present application provides a perception processing method, and the specific steps include:

[0079] Step 201: The terminal receives a first signaling, where the first signaling is used to indicate configuration information of one or more first signals that the terminal needs to measure; wherein, the first signaling is a signaling related to the perception service, the first signaling is sent by the first cell through a first frequency domain resource, and the one or more first signals are sent by the first cell through one or more second frequency domain resources, that is, both the first frequency domain resource and the second frequency domain resource belong to the first cell; or, the first signaling is sent by the first cell, and the one or more first signals are sent by the second cell.

[0080] That is to say, the terminal can receive the first signaling sent by the first cell through the first frequency domain resource, where the first signaling is used to indicate configuration information of one or more first signals that the terminal needs to measure, and the one or more first signals are sent by the first cell through one or more second frequency domain resources, or the terminal can receive the first signaling sent by the first cell, where the first signaling is used to indicate configuration information of one or more first signals that the terminal needs to measure, and the one or more first signals are sent by the second cell.

[0081] Optionally, the first signaling may include a control signaling for the perception service.

[0082] Optionally, the first cell and the second cell may satisfy any one of the following:

[0083] 1) The first cell is a cell of the terminal's Master Cell Group (MCG), and the second cell is a cell of the terminal's Secondary Cell Group (SCG);

[0084] For example, the first cell is the Primary Cell (Pcell) or Secondary Cell (Scell) of the terminal's MCG, and the second cell is the Primary Secondary Cell (PScell) or Scell of the terminal's SCG.

[0085] 2) The first cell is a cell (e.g., PS cell or Scell) of the terminal's SCG, and the second cell is a cell (e.g., Pcell or Scell) of the terminal's MCG;

[0086] For example, the first cell is the PS cell or Scell of the terminal's SCG, and the second cell is the Pcell or Scell of the terminal's MCG.

[0087] 3) The first cell is the first Scell, and the second cell is the second Scell. The first Scell and the second Scell belong to the terminal's MCG, or the first Scell and the second Scell belong to the terminal's SCG;

[0088] 4) The first cell is the Pcell, and the second cell is the Scell. The Pcell and the Scell belong to the terminal's MCG, or the Pcell and the Scell belong to the terminal's SCG;

[0089] 5) The first cell is the Scell, and the second cell is the Pcell. The Pcell and the Scell belong to the terminal's MCG, or the Pcell and the Scell belong to the terminal's SCG;

[0090] 6) The first cell is the serving cell of the terminal, and the second cell is the neighboring cell of the terminal.

[0091] Optionally, the above MCG and SCG can use the same or different radio access technologies (RATs). For example, the MCG and SCG use the fourth-generation mobile communication technology (4G) and the fifth-generation mobile communication technology (5G) respectively, or the MCG and SCG use 5G and 6G respectively, or the MCG and SCG use 4G and 6G respectively.

[0092] In this application, a cell can include at least one frequency-domain unit. The frequency-domain unit can include a set of continuous frequency-domain resources. The types of frequency-domain resources can include at least one of bandwidth, carrier, subband, Bandwidth Part (BWP), etc. If a cell includes multiple frequency-domain units, the sizes of each of the multiple frequency-domain units can be the same or different, and the different frequency-domain units may not be continuous.

[0093] Optionally, the above bandwidth, carrier, sub-band, and BWP can be Supplementary Uplink (SUL) or Supplementary Downlink (SDL).

[0094] See Figure 3 , the first cell includes one or more first frequency-domain resources and one or more second frequency-domain resources. There may be a frequency-domain interval or a guard band between different frequency-domain resources. It should be noted that the number of the first frequency-domain resources and the second frequency-domain resources in the first cell is not specifically limited.

[0095] In an embodiment of the present application, when the terminal receives the first signaling through the first frequency-domain resource of the first cell, the first signaling is further used to indicate the configuration information of one or more second signals that the terminal needs to send. Alternatively, another signaling different from the first signaling is used to indicate the configuration information of one or more second signals that the terminal needs to send, that is, the terminal receives the second signaling through the first frequency-domain resource of the first cell, and the second signaling is used to indicate the configuration information of one or more second signals that the terminal needs to send.

[0096] In an embodiment of the present application, the one or more second signals are sent by the terminal through one or more third frequency-domain resources of the first cell.

[0160] Optionally, the second indicator includes at least one of the following 2a) to 2c):

[0161] 2a) The fourth indicator;

[0162] The fourth indicator is the sum (in watts) of the linear average of the power of the other paths except the sensed target associated path in the channel response of the first signal on the target resource and the linear average of the interference and noise power of the other signals except the first signal on the first resource. The first resource is the target resource or other resources other than the target resource. The target resource includes the resource unit carrying the first signal, and the resource unit can be a time-domain resource or a frequency-domain resource;

[0163] Optionally, the fourth indicator = total received power - the first indicator; where the total received power can be expressed as: the linear average (in watts) of the total received power on the target resource (including the received power of the signals of the serving cell and non-serving cells, adjacent channel interference and thermal noise, etc.); or, the total received power = Received Signal Strength Indication (RSSI) * K1, where K1 is a coefficient, and the measurement resource of RSSI is the target resource or other resources (such as the resources configured by high-layer signaling).

[0164] 2b) The fifth indicator;

[0165] The fifth indicator is the linear average of the interference and noise power of the other signals except the first signal on the second resource. The second resource is the target resource or other resources other than the target resource;

[0166] Optionally, the fifth indicator = total received power - the received power of the first signal; where the received power of the first signal is the Reference Signal Receiving Power (RSRP) of the first signal.

[0167] 2c) The sixth indicator;

[0168] The sixth indicator is the linear average (in watts) of the power of the other paths except the sensed target associated path in the channel response of the first signal on the target resource;

[0169] Optionally, the sixth indicator = the RSRP of the first signal - the first indicator;

[0170] 3) The third indicator;

[0171] Optionally, the third indicator includes at least one of the following 3a) to 3d):

[0172] 3a) The seventh indicator;

[0173] Optionally, the seventh indicator represents the first indicator divided by the fourth indicator, i.e., seventh indicator = first indicator / fourth indicator;

[0174] 3b) Eighth indicator;

[0175] Optionally, the eighth indicator represents the first indicator divided by the fifth indicator, i.e., eighth indicator = first indicator / fifth indicator;

[0176] 3c) Ninth indicator;

[0177] Optionally, the ninth indicator represents the first indicator divided by the sixth indicator, i.e., ninth indicator = first indicator / sixth indicator;

[0178] 3d) Tenth indicator;

[0179] Optionally, the tenth indicator represents the first indicator 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., tenth indicator = K2 * first indicator / total received power, where K2 is a coefficient.

[0180] In an embodiment of the present application, the calculation method of the first indicator is as follows:

[0181] 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(k)) to obtain the channel response, i.e., H(k) = Y(k) / X(k), where k = 0, 1, 2,..., K - 1 represents the resource element index. After the terminal obtains the channel response H(k), it transforms it to the first dimension and determines the perception target associated path in the first dimension. Then, the power of the perception target associated path is calculated as the first indicator. If the perception target associated path includes multiple paths, the sum of the powers of the multiple paths is calculated as the first indicator.

[0182] Wherein, 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.;

[0183] For example, if H(f) is the channel response, where f = 0, 1, 2, …, n - 1 represents frequency-domain sampling points (such as 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 frequency-domain sampling points (such as subcarrier indices) and t = 0, 1, 2, …, M - 1 represents time-domain sampling points (such as 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 another example, if H(f, t, s) is the channel response, where f = 0, 1, 2, …, N - 1 represents frequency-domain sampling points (such as subcarrier indices), t = 0, 1, 2, …, M - 1 represents time-domain sampling points (such as Orthogonal Frequency Division Multiplexing (OFDM) symbol indices), and s = 0, 1, 2, …, P - 1 represents 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.

[0184] In this application, a method for determining a path associated with a sensing target (simply referred to as a sensing path) in the channel response measured for the first signal:

[0185] Step 1: Determine a 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 6 in, paths 0, 1, 2, 3 are the paths in the first path set);

[0186] Optionally, the preset threshold can be set to be higher than the noise threshold or higher than the noise interference threshold.

[0187] 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.

[0188] 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.

[0189] Optionally, the first condition includes at least one of the following:

[0190] 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;

[0191] 2) The Doppler of the path exceeds a preset threshold or lies within a preset range;

[0192] 3) The time delay of the path exceeds a preset threshold or lies within a preset range;

[0193] 4) The angle of the path exceeds a preset threshold or lies within a preset range;

[0194] 5) The difference in amplitude or power or intensity or energy between the path and the first-arriving path (e.g., the Line-of-Sight (LOS) path) or the reference path (e.g., the signal path reflected by a known target (such as a Reconfigurable Intelligence Surface (RIS) or Backscatter or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range;

[0195] 6) The Doppler difference between the path and the first-arriving path (e.g., the LOS path) or the reference path (e.g., the signal path reflected by a known target (such as a RIS or Backscatter device or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range;

[0196] 7) The time delay difference between the path and the first-arriving path (e.g., the LOS path) or the reference path (e.g., the signal path reflected by a known target (such as a RIS or Backscatter device or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range;

[0197] 8) The angle difference between the path and the first-arriving path (e.g., the LOS path) or the reference path (e.g., the signal path reflected by a known target (such as a RIS or Backscatter device or other known passive targets, etc.)) exceeds a preset threshold or lies within a preset range;

[0198] 9) The amplitude or power or intensity or 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.

[0199] It should be noted that the above first condition for each item can also be based on the statistical results over a period of time; for example, the proportion of the above indicators (such as the Doppler of the path, the time delay of the path, etc.) exceeding the preset threshold or lying within the preset range reaches a preset proportion within a preset time window, or the number of times the above indicators (such as the Doppler of the path, the time delay of the path, etc.) exceed the preset threshold or lie within the preset range reaches a preset number within the preset time window;

[0200] Among them, the preset threshold or set range is sent by other devices to the receiving device, and 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.

[0201] Among them, the prior perception information or perception requirements include at least one of the following:

[0202] 1) Perception service or perception service type;

[0203] 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-sectional area (RCS) 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 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 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;

[0204] 2) Perception target area;

[0205] 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 range of the time delay of the perception target association path is determined according to the approximate position or distance of the perception object.

[0206] 3) Perception object type;

[0207] 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.

[0208] 4) Number of perceived targets;

[0209] Optionally, as a kind of perception prior information, the camera perception result can be used to obtain the number of perceived targets;

[0210] For example, Figure 6 The medium diameters 0, 1, 2, 3 are the diameters in the first diameter set, where the diameters 2, 3 are the perceived diameters that meet the first condition (for example, their time delays meet the preset threshold), and the diameters 0, 1 are the diameters associated with other scatterers. Figure 6 The horizontal axis in the middle is the first dimension, and the vertical axis is the normalized amplitude or power or intensity or energy.

[0211] 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.

[0212] In another embodiment of the present application, the calculation method of the first metric is as follows:

[0213] 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 N1 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.

[0214] In one embodiment of the present application, the calculation method of the received power of the first signal is as follows:

[0215] 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.

[0216] In another embodiment of the present application, the calculation method of the received power of the first signal is as follows:

[0217] The received power of the first signal can also be the sum of the powers of all diameters in the first diameter set in the first dimension and The difference, where N2 represents the number of paths in the first path set.

[0218] The calculation method of the total received power:

[0219] Total received power

[0220] In an implementation manner of the present application, the calculation method of the third index:

[0221] 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

[0222] 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 6 the amplitude or power or intensity or energy of the 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.

[0223] In an implementation manner of the present application, the calculation method of the fourth index is as follows:

[0224] 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 ftlter2 (k) after the second filtering process is calculated, that is, Y filter2 (k) = H filt2r2 (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

[0225] The second filtering process may be a noise interference suppression process in the first dimension (for example Figure 6 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.

[0226] In another embodiment of the present application, the calculation method of the fourth index is as follows:

[0227] 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.

[0228] 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:

[0229] Method 1: Calculate the target index of each sensing target respectively. For example, in Figure 6 , 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).

[0230] Method 2: Calculate a target index for multiple sensing targets. For example, in Figure 6 , 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.

[0231] Optionally, the sensing requirements include at least one of the following:

For example, it can be classified into detection-type sensing services (such as intrusion detection, fall detection), parameter estimation-type sensing services (distance, angle, speed calculation), recognition-type sensing services (action recognition, identity recognition), etc. according to functions. It can also be classified according to the sensing range (close-range sensing, medium-range sensing, long-range sensing), according to the sensing fineness (coarse-grained sensing, fine-grained sensing, etc.), according to power consumption or energy consumption, according to resource occupancy, etc.

Specifically, the signal usage can also be used to indicate which perception service the signal is for, or which type of perception service the signal is for.

For example, for a self-transmitting and self-receiving sensing signal, R_max represents the maximum distance from the sensing signal transceiver point to the signal transmitting point; in some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval; c is the speed of light.
