The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0040] 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, but 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 technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0041] To facilitate understanding of the embodiments of this application, the following technical points are first introduced:

[0042] 1. Regarding the integration of communication and perception.

[0043] Typical perception functions and application scenarios are shown in Table 1.

[0044] Table 1: Typical perception functions and application scenarios.

[0045] Communication and perception integration (abbreviated as synaesthesia integration) is to achieve the integrated design of communication and perception functions through spectrum sharing and hardware sharing in the same system. While transmitting information, the system can perceive information such as direction, distance, and speed, and detect, track, and identify target devices or events. The communication system and the perception system complement each other to achieve overall performance improvement and bring a better service experience.

[0046] The integration of communications and radar is a typical application of communication-perception integration (communication-perception fusion). In the past, radar and communication systems were strictly separated due to their different research objectives and focus, and in most scenarios, the two systems were studied independently. In reality, radar and communication systems are both typical means of transmitting, acquiring, processing, and exchanging information, and they share many similarities in their operating principles, system architecture, and frequency bands. The design of integrated communications and radar is highly feasible, primarily due to the following aspects: First, both communications and perception systems are based on electromagnetic wave theory, utilizing the transmission and reception of electromagnetic waves to acquire and transmit information. Second, both communications and perception systems possess antennas, transmitters, receivers, and signal processors, resulting in significant overlap in hardware resources. With technological advancement, the operating frequency bands between the two systems are increasingly overlapping. Furthermore, there are similarities in key technologies such as signal modulation, reception detection, and waveform design. The integration of communications and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, improved spectrum efficiency, and reduced mutual interference, thereby improving overall system performance.

[0047] Depending on the difference between the first signal sending node and the receiving node, there are six basic sensing modes, as shown in Figure 1, including:

[0048] (1) Base station echo sensing: In this sensing mode, base station A sends a first signal and performs sensing measurement by receiving the echo of the first signal.

[0049] (2) Inter-base station air interface sensing: Base station B receives the first signal sent by base station A and performs sensing measurements.

[0050] (3) Uplink air interface perception: Base station A receives the first signal sent by terminal A and performs perception measurement.

[0051] (4) Downlink air interface perception: Terminal B receives the first signal sent by base station B and performs perception measurement.

[0052] (5) Terminal echo perception: Terminal A sends a first signal and performs perception measurement by receiving the echo of the first signal.

[0053] (6) Sidelink (SL) perception between terminals: Terminal B receives the first signal sent by terminal A and performs perception measurement.

[0054] It's worth noting that each perception method in Figure 1 uses a first signal transmitting node and a first signal receiving node as examples. In actual systems, one or more different perception methods can be selected based on different perception use cases and perception requirements, and each perception method can have one or more transmitting nodes and one or more receiving nodes. The perception targets in Figure 1 use people and vehicles as examples, assuming neither person nor vehicle carries or installs signal transmitting or receiving equipment. In actual scenarios, the perception targets are much richer.

[0055] Perception services can be supported by receiving or sending the first signal. For example, a perception measurement value or perception result can be obtained by receiving or sending the first signal. The perception result refers to a result that meets the perception requirements, such as: the shape of the perception target, two-dimensional (Two Dimensions, 2D) or three-dimensional (Three Dimensions, 3D) environment reconstruction, spatial position, orientation, displacement, moving speed, acceleration; radar-type perception of the target object's speed, distance, angle measurement or imaging; the presence of a person or object; perception targets such as human movements, gestures, breathing rate, heart rate, sleep quality, etc.

[0056] The first signal or the second signal in the present application may be a signal that does not contain transmission information, such as an existing LTE or New Radio (NR) synchronization and reference signal, including a synchronization signal and a physical broadcast channel (Synchronization Signal and PBCH block, SSB) signal, a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a sounding reference signal (SRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), etc.; it may also be a single-frequency continuous wave (CW), a frequency modulated continuous wave (FMCW), and an ultra-wideband Gaussian pulse commonly used in radar; it may also be a newly designed dedicated signal with good correlation characteristics and a low peak-to-average power ratio, or a newly designed synaesthesia integrated signal that carries certain information and has good perception performance. For example, the dedicated signal is formed by splicing, combining, or superimposing at least one dedicated first signal, a dedicated second signal, or a reference signal and at least one communication signal in the time domain or the frequency domain.

[0057] The sensing function network element in this application may also be referred to as a sensing network element or a sensing function, and may be located on the radio access network (RAN) side or the core network side. The sensing function network element may include a radio access network device or a core network device. The sensing function network element may be a network node in the core network or RAN that has at least one function, such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. For example, it may be an upgrade based on the access and mobility management function (AMF) or location management function (LMF) in the 5G network, or it may be another network node or a newly defined network node. Specifically, the functional characteristics of the sensing function network element may include at least one of the following:

[0058] (1) interacting with a wireless signal transmitting device or a wireless signal measuring device (including a target terminal or a serving base station of the target terminal or a base station associated with a target area) for target information, wherein the target information includes a sensing processing request, sensing capability, sensing auxiliary data, a sensing measurement quantity type, sensing resource configuration information, etc., to obtain the value of the target sensing result or the sensing measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; wherein the wireless signal may also be a first signal.

[0059] (2) The sensing method to be used is determined based on factors such as the type of sensing service, sensing service consumer information, required sensing service quality (QoS) requirement information, sensing capability of the wireless signal transmitting device, and sensing capability of the wireless signal measuring device. The sensing method may 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.

[0060] (3) The perception device serving the perception service is determined based on factors such as the type of perception service, information about the perception service consumer, required perception QoS requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device. The perception device includes a wireless signal sending device or a wireless signal measuring device.

[0061] (4) Manage the overall coordination and scheduling of resources required for sensing services, such as configuring sensing resources at base stations or terminals;

[0062] (5) Process the values ​​of the perceived measurement quantities, or perform calculations to obtain the perceived results. Furthermore, the perceived results are verified, and the perceived accuracy is estimated.

[0063] 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 (Wearable Device), a vehicle user equipment (VUE), a pedestrian terminal (Pedestrian User Equipment, PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, televisions, washing machines or furniture, etc.), a game console, a personal computer (PC), an ATM or a self-service machine and other terminal-side devices. Wearable devices include: smart watches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, game consoles, etc. It should be noted that the embodiments of the present application do not limit the specific type of the terminal.

[0064] The core network equipment in this application may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (MME), AMF, LMF, session management function (SMF), user plane function (UPF), policy control function (PCF), policy and charging rules function unit (PCRF), edge application service discovery function (EASDF), unified data management (UDM), unified data repository (UDR), home subscriber server (HSS), centralized network configuration (CNC), network storage 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 equipment in the NR system is introduced as an example, and the specific type of the core network equipment is not limited.

[0065] 2. About control resource set (CORESET) and search space (SS).

[0066] A CORESET is a collection of time and frequency domain resources for control information. CORESET#0 is a special CORESET that is typically used to schedule the transmission of the PDCCH in System Information Block (SIB) 1. The configuration information for CORESET#0 and the monitoring timing configuration for the Type 0 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 for the Type 0 PDCCH CSS and the size of the monitoring timing for the Type 0 PDCCH CSS.

[0067] There are two types of search space sets: a common search space set (CSS set) monitored by a group of terminals (e.g., User Equipment (UE)) in a cell, and a UE-specific 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 types of search spaces in NR:

[0068] 1) Type0-PDCCH common search space set (CSS set), used to monitor SIB1 system messages.

[0069] 2) Type0A-PDCCH CSS set, used to monitor system messages other than SIB1.

[0070] 3) Type 1-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 two-step random access process newly added in the related art.

[0071] 4) Type2-PDCCH CSS set, used to monitor paging messages.

[0072] 5) Type 3-PDCCH CSS set, used to monitor uplink power control PDCCH, preemption PDCCH, slot format indication PDCCH, and PDCCH related to downlink data transmission.

[0073] 6) USS set, used to monitor PDCCH related to downlink data transmission.

[0074] CORESET solves the problem of the existence range of 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 location of the UE to detect (monitor) PDCCH (but only gives the time domain resources, that is, the duration (number of symbols) of CORESET in the time domain), and the specific time domain location of the UE monitor PDCCH is given by the monitoring occasion (MO) given by the search space. Such a design can achieve greater flexibility. CORESET can be configured in any frequency domain location (the configuration parameter Frequency Domain Resources Information Element (FrequencyDomainResources IE) is a bitmap of the physical resource block (PRB) number of the current bandwidth part (Band width Part, BWP). The search space solves the problem of how the UE searches.

[0075] 3. About PDCCH type.

[0076] The PDCCH is the only downlink control channel in NR, carrying downlink control information (DCI). DCI primarily includes resource scheduling information for the Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH), as well as uplink power control instructions, slot format information, and which PRBs and Orthogonal Frequency-Division Multiplexing (OFDM) symbols the UE does not map data to. After undergoing a series of scrambling, modulation, and coding processes, DCI is mapped to physical resources in units of Control Channel Elements (CCEs).

[0077] PDCCH types are mainly divided into three categories: common PDCCH, group PDCCH and UE-specific PDCCH.

[0078] The following, in combination with the accompanying drawings, describes in detail the perception processing method, apparatus, communication equipment and readable storage medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0181] In one embodiment of the present application, the first indicator is calculated as follows:

[0182] The terminal performs channel estimation based on the first signal sent (hereinafter represented by X(k)) and the received signal corresponding to the first signal (hereinafter represented by Y(k)) to obtain a 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 obtaining the channel response H(k), the terminal transforms it into a first dimension and determines the perception target association path in the first dimension. The power of the perception target association path is then calculated as a first indicator. If the perception target association path includes multiple paths, the sum of the powers of the multiple paths is calculated as the first indicator.

[0183] Wherein, the first dimension includes at least one of the following: delay dimension; Doppler dimension; azimuth dimension; elevation dimension, for example, delay-Doppler dimension, delay-Doppler-angle dimension, etc.;

[0184] For example, H(f) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and H(f) can be transformed into the delay dimension (first dimension) by performing an inverse Fourier transform on it. For another example, H(f, t) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and t = 0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., OFDM symbol index), and H(f, t) can be transformed into the delay-Doppler dimension (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, H(f, t, s) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and t = 0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., Orthogonal Frequency Division Multiplexing (OFDM)). Division Multiplexing (OFDM) symbol index), s = 0, 1, 2, ..., P-1 represents the spatial sampling point (antenna index or port index), then H(f, t, s) can be transformed into the delay-Doppler-angle dimension (first dimension) by performing inverse Fourier transform along the frequency domain dimension, Fourier transform along the time domain dimension, and Fourier transform along the antenna domain dimension.

[0185] In this application, a method for determining a path associated with a perception target (referred to as a perception path) in a channel response obtained by measuring a first signal is as follows:

[0186] Step 1: Determine a first path set. The first path set includes the paths whose amplitude, power, intensity, or energy exceeds a preset threshold after the channel response is transformed into the first dimension. (For example, in Figure 6, paths 0, 1, 2, and 3 are the paths in the first path set).

[0187] Optionally, the preset threshold may be set to be higher than the noise threshold or higher than the noise interference threshold.

[0188] It is understandable that the step of determining the first path set is optional, and the path associated with the perception target may be determined only according to step 2.

[0189] Step 2: Select a path that meets a first condition from the first path set or from all paths as the path associated with the perception target.

[0190] Optionally, the first condition includes at least one of the following:

[0191] 1) The amplitude, power, intensity or energy of the path exceeds a preset threshold or is within a preset range; for example, the preset threshold is 5 times the noise threshold;

[0192] 2) The Doppler of the path exceeds the preset threshold or is within the preset range;

[0193] 3) The path delay exceeds the preset threshold or is within the preset range;

[0194] 4) The angle of the path exceeds the preset threshold or is within the preset range;

[0195] 5) The difference between the amplitude, power, intensity, or energy of the signal path and the first arrival path (e.g., line-of-sight (LOS) path) or the reference path (e.g., the path of the signal reflected by a known target (e.g., Reconfigurable Intelligence Surface (RIS) or backscatter or other known passive targets)) exceeds a preset threshold or is within a preset range;

[0196] 6) The Doppler difference between the path and the first arrival path (e.g., LOS path) or the reference path (e.g., the path of the signal reflected by a known target (e.g., RIS or Backscatter device or other known passive target)) exceeds a preset threshold or is within a preset range;

[0197] 7) The delay difference between the path and the first arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target (e.g., RIS or Backscatter device or other known passive target)) exceeds a preset threshold or is within a preset range;

[0198] 8) The angle difference between the path and the first arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a known target (e.g., RIS or Backscatter device or other known passive target)) exceeds a preset threshold or is within a preset range;

[0199] 9) The amplitude, power, intensity, energy, or phase of the path satisfies a specific modulation rule, where the specific modulation rule is the modulation rule of the tag, backscatter device, or RIS. That is, the path associated with the perceived target may be a path modulated and reflected by the tag, backscatter device, or RIS.

[0200] It should be noted that each of the above first conditions may also be based on statistical results over a period of time; for example, the ratio of the above indicators (such as the Doppler of the path, the time delay of the path, etc.) exceeding a preset threshold or being within a preset range in a preset time window reaches a preset ratio, or the number of times the above indicators (such as the Doppler of the path, the time delay of the path, etc.) exceed a preset threshold or are within a preset range in a preset time window reaches a preset number of times;

[0201] The preset threshold or set interval range is sent by another device to the receiving device and is determined by the other device based on prior perception information or perception requirements. Alternatively, the preset threshold or set interval range is determined by the receiving device based on prior perception information or perception requirements.

[0202] The priori perception information or the perception requirement includes at least one of the following:

[0203] 1) Perceived services or perceived service types;

[0204] Optionally, the sensing 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 detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, breathing monitoring, heart rate monitoring, pulse monitoring, humidity or brightness or temperature or atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building or vegetation distribution detection Measurement, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; the perception service type can be to classify multiple different perception services according to certain characteristics, such as classification according to function 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., and can also be divided according to the range of perception (close-range perception, medium-range perception, long-range perception), according to the degree of perception refinement (coarse-grained perception, fine force perception, etc.), according to power consumption or energy consumption, according to resource occupancy, etc. If the perception service is respiratory monitoring, the corresponding normal respiratory rate can be determined according to the person's gender and age (for example, male: 13 to 21 times / minute, female 15 to 20 times / minute; adult: 12 to 20 times / minute, child: about 30 to 40 times / minute), which can be used as perception prior information;

[0205] 2) Sense the target area;

[0206] Optionally, the perception target area includes a location area of ​​the perception object, or a location area where imaging or environmental reconstruction is required; for example, a preset interval range of the time delay of the perception target association path is determined according to the approximate location or distance of the perception object;

[0207] 3) Perceived object type;

[0208] Optionally, the sensed objects are classified according to their possible motion characteristics, and each sensed object type includes information such as a typical sensed object's motion speed range, motion acceleration range, and typical RCS range;

[0209] 4) Number of perceived targets;

[0210] Optionally, the camera perception result can be used as a perception prior information to obtain the number of perceived targets;

[0211] For example, in Figure 6, paths 0, 1, 2, and 3 are pathlets in the first pathlet set. Pathlets 2 and 3 are perceived pathlets that meet the first condition (e.g., their delays meet a preset threshold), and paths 0 and 1 are pathlets associated with other scatterers. In Figure 6, the horizontal axis represents the first dimension, and the vertical axis represents the normalized amplitude, power, intensity, or energy.

[0212] For frequency range 1, the reference point for 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 for a receiving channel must be obtained by measuring the combined signals of the multiple antenna elements corresponding to that receiving channel.

[0213] In another embodiment of the present application, the first indicator is calculated as follows:

[0214] Optionally, when calculating the received power of the perception target correlation path, the power of the perception target correlation path in the first dimension can be calculated. The difference between is taken as the first indicator, where N1 represents the number of paths associated with the perceived target. is the average power of multiple paths outside the first path set in the first dimension.

[0215] In one embodiment of the present application, the received power of the first signal is calculated as follows:

[0216] The received power of the first signal may be obtained by the receiving device, transforming the channel response (Channel Response) H(k) into a first dimension, determining a first path set in the first dimension, and then calculating the power sum of all paths in the first path set.

[0217] In another embodiment of the present application, the received power of the first signal is calculated as follows:

[0218] The received power of the first signal can also be the sum of the powers of all paths in the first path set in the first dimension and , where N2 represents the number of paths in the first path set.

[0219] The total received power is calculated as follows:

[0220] Total received power

[0221] In one embodiment of the present application, the third indicator is calculated as follows:

[0222] The channel response H(k) is processed by the first filter to obtain H filter1 (k), then according to H filter1 (k) and the first signal X(k) to obtain the received signal Y after the first filtering process filter1 (k), that is, Y filter1 (k)=H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the first filtering process. filter1 (k) Thus we get the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then calculate the third index

[0223] The first filtering process is used to eliminate noise and interference in the first dimension and paths not associated with the perceived target. For example, the first filtering process sets the amplitude, power, intensity or energy of paths other than the path associated with the perceived target in FIG6 to zero. The channel response H after the first filtering process filter1 (k) does not include noise, interference, or paths associated with non-perceived targets, but only includes paths associated with perceived targets.

[0224] In one embodiment of the present application, the fourth indicator is calculated as follows:

[0225] The channel response H(k) is processed by the second filter to obtain H filter2 (k), then according to H filter2 (k) and the first signal X(k) to obtain the second filtered received signal Y filter2 (k), that is, Y filter2 (k)=H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the second filtering process. filter2 (k) Thus we get the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then calculate the fourth index

[0226] The second filtering process may be a noise interference suppression process in the first dimension (for example, setting the amplitude, power, intensity or energy of the paths other than the first path set in FIG6 to zero), or a minimum mean square error (MMSE) filtering. The channel response H after the second filtering process is filter2 (k) does not contain noise and interference, and only contains the paths in the first path set.

[0227] In another embodiment of the present application, the fourth indicator is calculated as follows:

[0228] According to the average power of multiple paths outside the first path set in the first dimension Calculate the fourth index P σ2 ,Right now Where N represents the number of sampling points in the first dimension.

[0229] If the receiving device determines that multiple sensing targets are detected, or the receiving device obtains the number of sensing targets based on prior sensing information or sensing requirements, the following methods are available:

[0230] Method 1: Calculate the target indicator for each sensing target separately. For example, in Figure 6, the path associated with each sensing target is determined separately, and then the target indicators corresponding to each sensing target are calculated separately. When calculating the third indicator corresponding to a sensing target (such as sensing target A), there are two methods: the third indicator of sensing target A = total received power - the first indicator of sensing target A; or the third indicator of sensing target A = total received power - the first indicator of sensing target A - the first indicator of sensing target B (assuming there are two sensing targets: A and B). Similarly, there are two methods for calculating the fifth indicator: the fifth indicator of sensing target A = the RSRP of the first signal - the first indicator of sensing target A; or the fifth indicator of sensing target A = the RSRP of the first signal - the first indicator of sensing target A - the first indicator of sensing target B (assuming there are two sensing targets: A and B).

[0231] Method 2: Calculate a target metric for multiple perception targets. For example, in Figure 6, determine the paths associated with any perception target, and then use these paths as the paths associated with the perception target. This is equivalent to treating multiple perception targets as a virtual perception target and then calculating the target metric corresponding to the virtual perception target.

For example, for a self-transmitted and self-received perception signal, R_max represents the maximum distance from the perception signal receiving and transmitting 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.
