Description

Technical Field

[0001] The present application belongs to the field of communication perception technology, and specifically relates to a perception configuration method, device, communication equipment and storage medium. Background Art

[0002] Integrated Sensing and Communication (ISAC) has the potential to integrate wireless sensing into mobile networks (which can be called Perceptive Mobile Networks (PMNs)). Perceptive Mobile Networks can provide both communication and wireless sensing services. Due to their large broadband coverage and powerful infrastructure, they are expected to become a ubiquitous wireless sensing solution that can be widely used in communication and sensing in the fields of transportation, communication, energy, precision agriculture, and security.

[0003] In the related art, commonly used radar signals, such as Linear Frequency Modulation (LFM), have coupling between Doppler shift and distance. When the Doppler shift of the target echo is large, a large ranging error will be generated. The sidelobe level of the autocorrelation function of the nonlinear frequency modulation signal (Non LFM, NLFM) has been improved, but there is still a large distance sidelobe on the high Doppler frequency section of the ambiguity function. The sidelobe of a large target or clutter will cover the main lobe of a small target near the sidelobe. In a multi-target environment, the synthesis of the sidelobes of multiple target responses may even cover the main lobe of a stronger target response.

[0043] The present application relates to Integrated Sensing and Communication (ISAC) (abbreviated as "ISAC") technology, and the ISAC technology is first introduced below.

[0044] Wireless communication and radar sensing (Communication & Sensing, C&S) have been developing in parallel, but with limited overlap. They have a lot in common in terms of signal processing algorithms, equipment, and to some extent, system architecture. In recent years, traditional radars are moving towards a more general wireless sensing direction. Wireless sensing can broadly refer to retrieving information from received radio signals. For wireless sensing related to the location of the sensing target, the dynamic parameters such as the target signal reflection delay, arrival angle, departure angle, Doppler, etc. can be estimated through common signal processing methods; for sensing the physical characteristics of the target, it can be achieved by measuring the inherent signal patterns of the device / object / activity. The two sensing methods can be called perception parameter estimation and pattern recognition, respectively. In this sense, wireless sensing refers to more general sensing technologies and applications using radio signals.

[0045] Integrated Sensing And Communication (ISAC) has the potential to integrate wireless sensing into large-scale mobile networks, referred to here as Perceptive Mobile Networks (PMNs). Perceptive Mobile Networks are able to provide both communication and wireless sensing services, and are expected to become a ubiquitous wireless sensing solution due to their large broadband coverage and strong infrastructure. Perceptive Mobile Networks can be widely used for communication and sensing in the fields of transportation, communication, energy, precision agriculture, and security. It can also provide complementary sensing capabilities to existing sensor networks, with unique day and night operation capabilities, and the ability to penetrate fog, leaves, and even solid objects. Some common perception services are shown in Table 1 below:

[0046] Table 1

[0047]

[0048]

[0049] The base station in the mobile communication network (including one or more TRPs on the base station, user equipment (UE, also known as "terminal") (including one or more antenna subarrays / panels on the UE) can be used as a sensing device participating in the sensing / synesthesia integration service. By sending and receiving sensing signals by the sensing device, it is possible to sense a certain area or a certain physical target. The sensing signal can be a signal that does not contain transmission information, such as the existing LTE / NR synchronization and reference signals (including: synchronization signal and physical broadcast channel (Synchronization Signal and PBCHblock, SSB) signal, channel state information (CSI) reference signal (CSIReference Signal, CSI-RS), demodulation reference signal (Demodulation Reference Signal, DMRS), channel sounding reference signal (Sounding Reference Signal, SRS), positioning reference signal (PositioningReference Signal, PRS), phase tracking reference signal (Phase-Tracking Reference Signal, PTRS), etc.), or it can be a single-frequency continuous wave (Continuous Wave, CW), Frequency Modulated CW, FMCW, and ultra-wideband Gaussian pulse. In addition, the perception signal can also be a newly designed dedicated perception signal with good correlation characteristics and low peak-to-average power ratio (PAPR), or a newly designed synaesthesia integrated signal, which not only carries certain information but also has good perception performance. The type of perception signal is not specifically limited here. The first signal involved in the present application may include any of the above perception signals.

[0050] In the embodiments of the present application, the sensing signal sending device and the sensing signal receiving device may be the same device or different devices, for example: sensing device A sends a first signal, and sensing device B receives the first signal, and the sensing device A and the sensing device B are not the same device, and are physically separated; or, the sensing device A sends and receives the first signal by itself, that is, the sending and receiving of the sensing signal are performed by the same device, and the sensing device senses by receiving the signal echo sent by itself. For the sake of convenience, the embodiments of the present application are illustrated by taking the sensing signal sending device and the sensing signal receiving device as different devices as an example, which does not constitute a specific limitation here.

[0051] The design of perception / synaesthesia integrated signal is the focus of synaesthesia integrated technology research. The distance resolution and speed (radial) resolution of the perception / synaesthesia integrated signal depend on the selected signal form. The wider the frequency band occupied by the perception / synaesthesia integrated signal in the frequency domain, the better its distance resolution; the larger the continuous width of the perception / synaesthesia integrated signal in the time domain, the better its speed resolution. Designing the perception / synaesthesia integrated signal from the perspective of improving perception / resolution requires that the main peak of the fuzzy function of the perception / synaesthesia integrated signal is high and sharp, and the secondary peak is low and flat. Radar signals in related technologies, such as Linear Frequency Modulation (LFM), have coupling between Doppler shift and distance. When the Doppler shift of the target echo is large, a large ranging error will be generated. The sidelobe level of the autocorrelation function of the nonlinear frequency modulation signal (Non LFM, NLFM) has been improved, but there are still large distance sidelobes on the high Doppler frequency section of the ambiguity function. The sidelobes of large targets or clutter will cover the main lobe of small targets near the sidelobes. In a multi-target environment, the synthesis of the sidelobes of multiple target responses may even cover the main lobe of the stronger target response. It can be seen that the related technologies have the problem of poor signal perception performance. If the signal form of the radar signal in the related technologies is applied to the perception signal, it will lead to poor signal perception performance.

[0052] In LTE and NR systems, pseudo-random sequences (including m-sequences and Gold sequences) and Zadoff-Chu sequences (ZC sequences for short) are widely used in various reference signals and channels, as shown in Table 2 [2].

[0053] Table 2 Sequences used for the main reference signals and channels of LTE and NR

[0054] Reference signal / channel LTE NR PSS ZC Sequence m-sequence SSS m-sequence Gold Sequence DMRS Downlink: Gold sequence; Uplink: ZC sequence Gold Sequence CSI-RS Gold Sequence Gold Sequence PTRS / Gold Sequence PRS Gold Sequence Gold Sequence SRS Gold sequence or ZC sequence ZC Sequence PRACH ZC Sequence m-sequence PUCCH ZC Sequence ZC sequence or Gold sequence

[0055] The ZC sequence is a subcarrier phase sequence, which is a phase modulation at any angle. 5G application scenarios include high-frequency bands 5G-60GHz. The use of phase modulation at any angle causes the ZC sequence to have a larger frequency deviation in the high-frequency band, for example, 5ppm is as high as 300kHz at 60GHz. Its correlation is affected, which is manifested as a decrease in the peak-to-peak value of the correlation and an increase in false detection, so the m-sequence is used instead. LTE uses ZC because of its good autocorrelation and cross-correlation, and LTE is mainly in the 2GHz frequency band, so the time-frequency deviation is relatively small. 5G uses the m-sequence, and the underlying layer uses binary phase shift keying (BPSK) modulation. The phase of each subcarrier is two deterministic values, not an arbitrary value. Therefore, the problem of difficult phase difference detection caused by high frequency is overcome by BPSK modulation.

[0056] The following is a brief introduction to the relevant sequences in conjunction with Table 2:

[0057] (1) ZC sequence

[0058] The ZC sequence is a low peak-to-average ratio sequence with a constant envelope. It is used in the Physical Random Access Channel (PRACH) and the Physical Uplink Control Channel (PUCCH) in the 5G NR system. In the LTE system, the Primary Synchronisation Signal (PSS), the Uplink Demodulation Reference Signal (DMRS), the Sounding Reference Signal (SRS), PRACH, and PUCCH all involve the ZC sequence. The SRS signal and PUCCH in the NR system also involve the ZC sequence.

[0059] The generation of ZC sequence in NR is illustrated by taking 5G NR SRS as an example. The sequence length of 5G NR SRS is generated according to the bandwidth configured by a terminal rather than the system bandwidth.

[0063] in, m SRS,b Given by Table 6.4.1.4.3-1 in the 3rd Generation Partnership Project (3GPP) Technical Specifications (TS) 38.211, K is the number of subcarriers contained in a physical resource block (PRB); TC Combination number, value is 2, 4, 8, configured by high-level signaling, δ = log2 (K TC ).

[0067] 5G NR defines two low PAPR sequences (Type 1 and Type 2), where the ZC sequence for transmission is generated by the base sequence Cyclic shift α to get

[0069] Here, there are two cases according to the sequence length. In the case of

[0075]

[0077]

[0078] (2) m-sequence

[0079] In the 5G NR system, 1008 cell IDs are used to identify wireless cells. These 1008 IDs are divided into 336 groups, each of which consists of a cell ID group. Identification, each group contains 3 different sectors, by the cell ID sector Identification. UE detects based on PSS According to SSS test Based on the above detection, the UE can Get the serving cell ID. Take 5G NR PSS as an example to illustrate the generation of m sequence in NR. 5G NR PSS uses a sequence of length 127. Sequence d PSS (n) is calculated as follows:

[0080] d PSS (n) = 1-2x(m)

[0081]

[0082] 0≤n<127 (8)

[0083] Among them, x(i+7)=(x(i+4)+x(i))mod2, and [x(6) x(5) x(4) x(3) x(2) x(1) x(0)]=[1 1 1 0 1 1 0].

[0084] (3) Gold sequence

[0085] Take 5G NR SSS as an example to illustrate the generation of Gold sequence in NR. 5G NR SSS uses Gold sequence of length 127, with a total of 336. The sequence definition is as follows:

[0086] d SSS (n)=[1-2x0((n+m0)mod127)][1-2x1((n+m1)mod127)]

[0087]

[0088]

[0091] [x0(6) x0(5) x0(4) x0(3) x0(2) x0(1) x0(0)]=[0 0 0 0 0 0 1],

[0092] [x1(6) x1(5) x1(4) x1(3) x1(2) x1(1) x1(0)]=[0 0 0 0 0 0 1].

[0093] For the above sequences, taking ZC sequence / m sequence as an example, their cross-correlation peak lower bound is approximately Where L is the sequence length. Therefore, if the above sequence is applied to the perception / synaesthesia integration service, the cross-correlation peak in the configured perception parameter estimation area is not zero, and there is energy interference, which makes the perception / synaesthesia integration performance poor.

[0094] In view of this, the embodiment of the present application provides a method for perceiving configuration based on a ZCZ sequence by applying a zero correlation zone (Zero Correlation Zone, ZCZ) sequence to a perception / synaesthesia integration service. Compared with the perception configuration scheme based on a ZC sequence / m sequence, since there is zero correlation between ZCZ sequences, the perception parameters configured therein have near-perfect autocorrelation and cross-correlation characteristics within the estimation area, that is, the cross-correlation peak is 0, and there is almost no energy interference. In this way, better perceiving / synaesthesia integration performance can be achieved under the same time-frequency resource configuration.

[0103] The following is a brief introduction to the ZCZ sequences:

[0104] ZCZ sequences have been used in asynchronous and quasi-synchronous code division multiple access (CDMA) systems to achieve synchronization and reduce multiple access interference and multipath interference. In the field of radar, there are also studies that apply ZCZ sequences to phase-coded multiple-input multiple-output (PC MIMO) radars. For details, see [3] and [4]. First, assume that the sequence of length L is represented by The sequence set {c r ,...,c M-1} can be expressed as Two sequences of length L are c r ,c s The periodic cross-correlation function with respect to the time delay τ is

[0105]

[0106] The definition of the ZCZ sequence is as follows:

[0107] If sequence set At the same time, the following conditions are met:

[0108]

[0109] Then the sequence set The sequence in is called ZCZ sequence, and the sequence set is represented by a triple (L, M, Z). M is the number of sequences in the ZCZ sequence set, L is the length of the ZCZ sequence, and Z is the size of the region of the ZCZ sequence that satisfies zero cross-correlation (dimensionless). Theory shows that there is an upper bound on the value of Z.

[0110] The ZCZ sequence can be generated using m-sequence, ZC sequence, Walsh sequence, or Hadamard matrix row / column vector as the basis sequence. The specific generation method can be found in [5]-[7] and will not be described in detail here.

[0111] The use of ZCZ sequence in the orthogonal frequency division multiplex (OFDM) system is as follows:

[0112] The ZCZ sequence can realize at least one of the following functions in the OFDM system: delay (i.e., target distance) estimation, Doppler frequency (i.e., target speed) estimation, and channel estimation. When the ZCZ sequence is used in the MIMO system, the theoretically optimal single target / multi-target angle estimation can be realized in a specific zero cross-correlation region.

[0113] Assume a MIMO-OFDM system with N antennas. tx , from the ZCZ sequence set According to the predetermined rules, N sequences are selected from a total of M sequences. tx ≤M sequences are used as transmission signal sequences. When the ZCZ sequence is used for delay estimation and / or wideband channel estimation, the frequency domain modulation symbol corresponding to the mth antenna is:

[0114]

[0115] That is, we need to m After the discrete Fourier transform (DFT), it is mapped to each subcarrier in the frequency domain. c is the number of OFDM signal subcarriers used for perception, satisfying N c = L. After DFT, the ZCZ sequence is mapped to different OFDM resource elements (REs) and occupies a certain bandwidth. The OFDM signal is transformed into a time domain signal after inverse discrete Fourier transform (IDFT). The time domain sequence sent at this time is The receiving end can receive in the frequency domain, and obtain the frequency domain received signal vector by conjugating the received frequency domain signal with the known ZCZ sequence frequency domain signal, and then perform IDFT in the frequency dimension to obtain the delay power spectrum. Alternatively, the time domain received signal sequence is matched filtered in the time domain to directly obtain the delay power spectrum.

[0116] It should be noted that (1) when a single port is configured, both frequency domain conjugate multiplication and frequency domain point division can be used. When the ZCZ sequence uses constant modulus modulation (such as BPSK or Quadrature Phase Shift Keying (QPSK)), frequency domain conjugate multiplication and point division are equivalent. However, in the low perceived signal-noise ratio (SNR) area, conjugate multiplication has better performance than point division; (2) After the ZCZ sequence is converted to the frequency domain by DFT, it does not meet the frequency domain constant modulus. At this time, conjugate multiplication and point division are not equivalent. In order to utilize the zero cross-correlation characteristics of the ZCZ sequence in region Z, frequency domain conjugate multiplication is used here; (3) Theoretical derivation shows that the frequency domain conjugate multiplication and time domain matched filtering have similar effects, both of which include signal cross-correlation operations, so they can be used to distinguish signals from different MIMO transmission ports; and the ZCZ sequence can achieve zero cross-correlation in region Z in this scenario.

[0117] If Doppler frequency measurement is to be performed, then optionally, based on the above delay estimation and / or wideband channel estimation method, the same or different ZCZ sequences are placed on different OFDM symbols in the time domain according to a preset symbol interval, such as Figure 2a , Figure 2b As shown. In this case, the receiving end can receive in the frequency domain, and obtain the frequency domain receiving data matrix by conjugate multiplication or dot division of the received frequency domain signal and the known ZCZ sequence frequency domain signal, and then perform DFT in the time dimension to obtain the Doppler power spectrum; or, perform matched filtering on the time domain receiving signal in the time domain, obtain multiple groups of matched filtering outputs and splice them into a receiving data matrix, and then perform DFT in the time dimension to obtain the Doppler power spectrum. Optionally, the ZCZ sequence can also be directly placed on the continuous symbols corresponding to a certain subcarrier, such as Figure 2c In this case, there is no need to first transform to the frequency domain through DFT. After receiving the complete sequence, the receiver obtains the Doppler power spectrum through frequency domain conjugate multiplication or dot division, or directly obtains the Doppler power spectrum through time domain matched filtering.

[0118] If you need to measure both the time delay and the Doppler frequency, you can use Figure 2a , Figure 2b In addition, the delay and Doppler can be measured separately, for example, the ZCZ sequence is first transformed by DFT and mapped to the frequency domain to obtain the delay estimation, and then the ZCZ sequence elements are mapped to different OFDM symbols in the time domain to obtain the Doppler estimation. The ZCZ sequences used in the two measurements can be different, depending on the perception requirements, such as Figure 2d shown.

[0119] The following, in combination with the accompanying drawings, describes in detail the perception configuration method, apparatus, communication equipment and storage medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0120] Figure 3 A flow chart of a perception configuration method provided by an embodiment of the present application is shown. Figure 3 As shown, the perception configuration method includes the following steps:

[0121] Step 301: The first device obtains first information;

[0122] Step 302: The first device determines first ZCZ sequence related information based on the first information, where the first ZCZ sequence related information is used for sensing configuration.

[0123] In addition to determining the first ZCZ sequence related information based on the first information, the first device can also determine other information related to the perception configuration, such as perception signal power parameters, etc. The first ZCZ sequence related information can be understood as the related information used to determine the ZCZ sequence. After the ZCZ sequence is determined, the configuration information (such as resource configuration information) of the perception signal can be determined, and the perception signal sending device can send the perception signal based on the determined ZCZ sequence. Correspondingly, the perception signal receiving device can also receive the perception signal based on the determined ZCZ sequence. Therefore, the first ZCZ sequence related information can also be understood as a kind of perception signal configuration information. In order to distinguish the perception signal configuration achieved by other means, the first ZCZ sequence related information can be specifically understood as ZCZ perception signal configuration information.

[0124] In the embodiment of the present application, the first ZCZ sequence related information is determined based on the first information, and the first information may include at least one of perception information, communication information, and perception resource information.

[0126] If the first device is a core network device, after the first device determines the first ZCZ sequence related information, the first ZCZ sequence related information may be sent to the second device. The second device may include, for example, a perception signal sending device and a perception signal receiving device. If the first device is a perception signal sending device, after the first device determines the first ZCZ sequence related information, the first ZCZ sequence related information may be sent to the perception signal receiving device. The perception signal receiving device may include, for example, a terminal, an access network device, and the like. The number of at least one of the perception signal sending devices and the perception signal receiving devices may be greater than 1, for example, at least one perception signal sending device sends the first ZCZ sequence related information to at least one perception signal receiving device, or the core network device sends the first ZCZ sequence related information to at least one perception signal sending device or at least one perception signal receiving device.

[0127] In the embodiment of the present application, the ZCZ sequence is applied to the perception / synaesthesia integration service, and the perception configuration is performed based on the ZCZ sequence. Compared with the perception configuration scheme based on the ZC sequence / m sequence, since there is zero cross-correlation between the ZCZ sequences, the perception parameters configured therein have near-perfect autocorrelation and cross-correlation characteristics in the estimation area, that is, the cross-correlation peak is 0, and there is almost no energy interference. In this way, better perception / synaesthesia integration performance can be achieved under the same time-frequency resource configuration.

[0136] Correspondingly, the second device may also determine the ZCZ sequence based on the first ZCZ sequence related information and perform perception / synaesthesia integrated signal configuration. After receiving the first signal, the second device may obtain a perception measurement value or a perception result.

[0142] In the case where the first information includes perceptual information, optionally, the perceptual information includes at least one of the following:

[0143] Perceived Quality of Service (QoS) information;

[0144] Perceive prior information;

The perceptual performance evaluation index may include at least one of the following:

[0169] 1) Perception signal-to-noise ratio (SNR), which is the ratio of the perception signal energy reflected by the perception object or perception area to the noise signal energy in the environment and the device;

[0174] 6) Cramér-Rao Lower Bound (CRLB), which is the lowest variance that can be achieved by all unbiased estimators. Mathematically, it is equal to the inverse of Fisher information. This evaluation index is related to the perceived SNR.

[0175] 7) Capacity-Distortion Tradeoff, which quantitatively gives the maximum achievable rate of reliable transmission of the synaesthesia integrated system under given distortion constraints;

[0180] 12) A calculation result obtained by performing at least one operation of addition, subtraction, multiplication and division on any at least two of the above-mentioned indicators such as perceived SNR, perceived SINR and CRLB.

[0181] Optionally, the perception-related identifier includes at least one of a perception area identifier, an identifier indicating whether to be used for perception, a perception service identifier, a perception service type identifier, a perception target identifier, a perception measurement amount identifier, and an identifier of a device participating in perception measurement.

[0182] The sensing area is a target area to be sensed that has been divided in advance. The sensing area and the sensing area identifier may include the following situations:

[0183] a) Multiple base station coverage areas (cells) form a perception area, associated with a perception area identifier n areaID ,like Figure 4 As shown, each hexagonal area represents a base station coverage area, and areas with the same pattern represent the same perception area. In particular, the access network notification area (RAN-based notification area, RNA) can be used as a perception area, and the RNA ID can be used as the perception area identifier.

[0184] b) A single base station coverage area (cell) contains multiple sensing areas, which are associated with multiple sensing area identifiers. For example, with the base station as the origin, its coverage area is rasterized and divided into multiple sensing areas, and each area is associated with an area ID, denoted as n. areaID ,like Figure 5 ,The dotted line represents the base station coverage area, and each square represents the divided sensing area.

[0185] c) Directly use geographic area identifiers such as latitude and longitude or coordinate positions that are independent of the base station location to generate area ID n areaID .

[0186] d) Different angle ranges relative to the base station are associated with different area IDs n areaID For example, the azimuth angle x1°~x2° and the pitch angle y1°~y2° correspond to the sensing area ID1.

[0187] When multiple devices perform joint perception of the same perception area, multiple devices use a common area ID to generate a perception signal. Optionally, the generation parameters of the perception signal are independent of the cell identifier or the UE identifier, that is, different sending devices can use the same perception signal generation parameters, which is convenient for further construction of code-division orthogonal perception signals (for example, a first perception signal is generated based on the same generation parameters, and different devices use the same first perception signal and different orthogonal cover codes (Orthogonal Cover Code, OCC) sequences to generate mutually orthogonal second perception signals for perception measurement). The receiving device can obtain the perception signal and perform measurement based on the same perception signal generation parameters and code-division orthogonal method, thereby reducing interference between signals of different devices, reducing signaling overhead, and improving measurement efficiency.

[0188] Flag indicating whether it is used for perception: For example, when the indication is not used for perception sensingID = 0; when the indication is used for perception n sensingID =1.

[0189] Perception service identifier: For example, different perception services correspond to different perception service IDs n sensingID , wherein the sensing service may include, for example, the following:

[0190] Detect whether the target exists, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, Radar Cross Section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, breathing monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.

[0191] Identification of the perception service type: Different categories correspond to different perception service IDs n sensingID , for example, the perception functions or business types are divided according to the scope scale, such as:

[0192] Category 1 (close distance / small range): material analysis, component analysis, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, breathing monitoring, heart rate monitoring, pulse monitoring, etc.

[0193] The second category (medium distance / medium range): intrusion detection, population counting, indoor positioning, etc.

[0194] The third category (long distance / large range): humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, etc.

[0195] Other classification standards can also be used, such as classification based on function into positioning perception, imaging perception, pattern recognition perception, etc.; it can also be classified according to power consumption / energy consumption, classification according to resource occupancy, etc.

[0196] Perception measurement quantity identifier: at least one of the perception measurement quantities is associated with a perception measurement quantity identifier, and Table 4 shows the perception measurement quantity IDs corresponding to various perception measurement quantities. The perception signal sending device may generate a perception signal according to different perception measurement quantity IDs.

[0197] Table 4 Perceptual measurement quantity ID

[0198] Perception measurement ID Perceptual Measurement ID1 Delay / Distance ID2 Doppler / speed ID3 angle ID4 Delay / distance, Doppler / speed ID5 Delay / distance, Doppler / speed, angle

[0199] The perception target identifier may be a tag identifier associated with the perception target. The perception signal sending device may obtain the perception target identifier. Different perception targets correspond to different perception target IDs. targetID, wherein the determination of the perception target may be based on a priori information obtained from existing measurement results, for example, base station A sends a perception measurement signal through an omni-directional beam for preliminary measurement, base station A obtains a distance-Doppler map (or a distance-angle map, etc.), determines the number of targets according to the distance-Doppler map, and assigns an ID to each target; or, base station A sends a perception measurement signal through an omni-directional beam for preliminary measurement, a perception signal receiving device (such as another base station or terminal) obtains a distance-Doppler map (or a distance-angle map, etc.), determines the number of targets according to the distance-Doppler map, assigns an ID to each target, and then notifies the sending base station of the target ID and / or target related information.

[0200] After the perception signal sending device determines the ID of each target, it generates signals for sensing different targets according to different target IDs, and these perception signals are sent using different beams, and the beam direction points to the perception target associated with the target ID;

[0201] The sensing target is equipped with a tag, and different tags are associated with different tag IDs. The sensing signal sending device obtains the tag ID of the corresponding target, and then obtains the signal used to sense different targets. The tag can be a device that supports backscatter communication, and its excitation source can be a device other than the tag, or the excitation source is the tag itself. It can also be a UE, that is, a common transceiver module is installed on the sensing target, such as a communication device such as a vehicle terminal installed on a car.

[0202] The perception target identifier can also be an identifier of the perception target type. Different perception target types correspond to different perception target IDs. For example, they are divided into stationary targets and moving targets. The latter can be further divided into high-speed targets and low-speed targets. Different types of targets correspond to different n targetID .

[0211] Antenna information, for example, may include antenna information of a sensing signal transmitting device or a sensing signal receiving device;

[0212] Codeword information.

[0213] The time domain resource information refers to information related to the time domain resources, such as a radio frame index, a subframe index, a slot index, a symbol index, a duration, a time domain density, a cyclic prefix (CP) type, a CP length, etc., and may also include a coherent processing time window index;

[0214] Frequency domain resource information refers to information related to frequency domain resources, which may include, for example, RE index, resource block (RB) index, frequency point information, frequency band information, bandwidth, frequency domain density, and subcarrier spacing);

[0215] The sensing resource block information may include, for example, a sensing resource block index, and the sensing resource block may include multiple PRBs and multiple time slots / symbols, that is, include specific time-frequency domain resources (for example, a two-dimensional FFT operation is performed to obtain a frequency domain resource length and a time domain resource length corresponding to a range-Doppler map);

[0216] The port information may include, for example, a port index of a perception signal sending device or a port index of a perception signal receiving device. Thus, by acquiring the port information, the port information of the perception signal sending device or the perception signal receiving device may be determined.

[0217] The antenna information may include, for example, an antenna index of a perception signal sending device or an antenna index of a perception signal receiving device. Thus, by acquiring the antenna information, the antenna information of the perception signal sending device or the perception signal receiving device may be determined.

[0218] The codeword information may include, for example, a codeword index.

[0219] Optionally, the first ZCZ sequence related information includes at least one of the following:

[0220] The first indication information is used to indicate a method for generating a ZCZ sequence. The method for generating a ZCZ sequence may include method 1 and method 2, wherein method 1 is to generate a ZCZ sequence based on a base sequence (e.g., an m sequence, a ZC sequence), and method 2 is to generate a ZCZ sequence based on a table lookup. In the embodiment of the present application, the first indication information may be used to indicate the specific method used to generate the ZCZ sequence, that is, the first indication information is used to indicate whether the method for generating the ZCZ sequence is based on a base sequence generation method or a table lookup generation method;

[0221] The second indication information is used to indicate the phase coding modulation order (or base) of the ZCZ sequence, that is, to indicate the m-PSK type of the ZCZ sequence, equivalently, to indicate the value of m. Common values ​​of m include 2 and 4, namely BPSK and QPSK. In addition, the value of m can also be any other integer greater than 1;

[0222] Structural information of ZCZ sequence;

[0223] Time-frequency resource parameters of the ZCZ sequence.

[0224] Optionally, the structural information of the ZCZ sequence includes at least one of the following:

[0225] The length L of the ZCZ sequence is equal to the number of continuous resources (subcarriers) mapped by the ZCZ sequence in the frequency domain resource span, or the number of continuous resources (OFDM symbols) mapped by the ZCZ sequence in the time domain resource span. If the configured perception signal uses more than one ZCZ sequence, this parameter contains more than one parameter value;

[0226] The number of ZCZ sequences in the ZCZ sequence set is M. This value indicates the maximum number of available sequences in the ZCZ sequence set used for perception / synaesthesia integration. If it is MIMO perception, N tx ≤M, where N tx Indicates the number of transmitting antennas;

[0227] The zero cross-correlation region length Z of the ZCZ sequence can be directly configured or associated with at least one of the ZCZ sequence length L, the number of ZCZ sequences in the ZCZ sequence set M, perceived QoS, perceived prior information, historical perceived measurement value, historical perceived result, and historical perceived performance evaluation index measurement value.

[0228] Regarding the zero cross-correlation region length Z of the ZCZ sequence, the following example is provided:

[0229] Example 1: A QPSK-based ZCZ sequence, where the length of the ZCZ sequence zero cross-correlation region is Z=2 i-2 ×3, where i = log2(L / M) = log2(N c / M), N c is the number of subcarriers, M is greater than or equal to the number of transmitting antennas N tx The smallest integer that satisfies Mmod4=0. In this example, the zero cross-correlation region length Z is directly associated with the ZCZ sequence length L and the number of ZCZ sequences M in the ZCZ sequence set, and the ZCZ sequence length L and the number of ZCZ sequences M in the ZCZ sequence set are associated with the perceptual resolution in the perceptual QoS;

[0230] Example 2: Assuming that prior information is known: the maximum delay spread of the channel between the sensory / synaesthesia integrated transmitter and receiver is T m , the distance between the transmitter and the receiver is D m , then the configuration of the zero cross-correlation region length Z satisfies Z≤T m +2D m / c. At this point, from the previous introduction to the ZCZ sequence related technology, it can be seen that the network can select appropriate L and M and ZCZ sequence generation method to construct a ZCZ sequence that meets the above Z value requirements.

[0231] Optionally, the time-frequency resource parameter of the ZCZ sequence includes at least one of the following:

[0232] The starting frequency of the perceived signal based on the ZCZ sequence. This parameter defines the lowest frequency position (Lowest Subcarrier) of the perceived signal, also known as the frequency reference point;

[0234] The duration of the perception signal based on the ZCZ sequence, which defines the total length of time occupied by the perception signal. The unit can be the number of time slots, the number of symbols, or the number of OFDM frames. The duration of the perception signal can include, for example, the number of consecutive time slots or symbols occupied by the perception signal;

[0235] The perception signal bandwidth based on the ZCZ sequence, which defines the total frequency domain width occupied by the perception signal. When the ZCZ sequence length L is determined, this parameter can be used together with L to determine the RE (subcarrier) interval of the ZCZ sequence frequency domain mapping; the perception signal bandwidth can include, for example, the number of consecutive PRBs occupied by the perception signal;

[0236] The frequency domain density of the perception signal based on the ZCZ sequence, which defines the RE (subcarrier) interval of the frequency domain mapping of the ZCZ sequence. The parameter can be directly configured by the network or determined by the perception signal bandwidth based on the ZCZ sequence and the ZCZ sequence length L. The frequency domain density of the perception signal may include, for example, the number of REs required for each PRB perception signal in the frequency domain, the frequency domain interval of the REs occupied by the perception signal in each PRB, and the frequency domain offset;

[0237] The time domain density of the perception signal based on the ZCZ sequence, which defines the RE (symbol) interval of the ZCZ sequence time domain mapping. The parameter can be directly configured by the network, or can be determined by the duration of the perception signal based on the ZCZ sequence and the ZCZ sequence length L or the number of time domain ZCZ sequences. The time domain density of the perception signal may include, for example, the number of symbols required for the perception signal in each time slot in the time domain, the symbol interval and symbol offset of the symbols occupied by the perception signal in each time slot;

[0238] Frequency offset of the perception signal based on the ZCZ sequence. This parameter controls the frequency offset of the lowest (or highest) frequency of the time-frequency resource mapped by the ZCZ sequence relative to the lowest (or highest) frequency in the available frequency band for the perception / synaesthesia integration service. The frequency offset can be represented by the number of REs or RBs.

[0239] The time offset of the perception signal based on the ZCZ sequence (Time Offset). This parameter controls the first time-frequency resource unit (RE) mapped by the ZCZ sequence in the time dimension. It is the time offset relative to the time resources available for the perception / synaesthesia integration service. The time offset can be expressed in terms of the number of OFDM symbols or the number of time slots.

[0240] The muted time positions in the ZCZ sequence, such as the muting pattern, can be used to define a bitmap to indicate which time (symbol / time slot) positions in a perception resource set the perception / synaesthesia integrated signal based on the ZCZ sequence will be muted and not transmitted;

[0241] Quasi Co-Location (QCL) information (i.e., QCL Information) between the time-frequency resources where the ZCZ sequence is located and other reference signals. This parameter defines the quasi co-location information between the time-frequency resources mapped by the ZCZ sequence and other reference signals.

[0242] Optionally, when the first indication information indicates that the ZCZ sequence is generated based on a base sequence, the first ZCZ sequence related information also includes base sequence related information.

[0243] Optionally, the base sequence includes at least one of an m-sequence, a Zadofff-Chu sequence (ZC sequence for short), a Walsh sequence, a Hadamard matrix row vector sequence, and a Hadamard matrix column vector sequence.

[0244] Optionally, the base sequence related information is predetermined based on the first information.

[0257] The index of the Walsh sequence used to generate the ZCZ sequence. When the ZCZ sequence generation method is a method based on base sequence generation and the base sequence is a Walsh code, this parameter indicates the Walsh code used to generate the ZCZ sequence;

[0258] The index of the Hadamard matrix used to generate the ZCZ sequence, and the row index of the Hadamard matrix. When the ZCZ sequence generation method is based on the basis sequence generation method, and the basis sequence is the row vector of the Hadamard matrix, this parameter indicates the Hadamard matrix used to generate the ZCZ sequence, and the row vector of the Hadamard matrix;

[0259] The index of the Hadamard matrix used to generate the ZCZ sequence, and the column index of the Hadamard matrix. When the ZCZ sequence generation method is based on the basis sequence generation method, and the basis sequence is the column vector of the Hadamard matrix, this parameter indicates the Hadamard matrix used to generate the ZCZ sequence, and the column vector of the Hadamard matrix.

[0260] Optionally, when the first indication information indicates that the ZCZ sequence is generated based on table lookup, the ZCZ sequence related information further includes at least one of the following:

[0261] ZCZ sequence set index, when the ZCZ sequence generation method is based on a table lookup method, this parameter indicates the ZCZ sequence set used for perceptual / synaesthesia integration;

[0262] ZCZ sequence index: when the ZCZ sequence generation method is based on a table lookup method, this parameter indicates the ZCZ sequence used by at least one transmit antenna port for perception / synaesthesia integration.

[0263] Optionally, the ZCZ sequence set corresponding to the ZCZ sequence set index is a ZCZ sequence set in a set of predefined ZCZ sequence sets, and in the set of predefined ZCZ sequence sets, ZCZ sequences of different ZCZ sequence sets have different structures.

[0264] The network may predefine a set containing at least one ZCZ sequence set, as shown below:

[0265] {(L pL ,M pM ,Z pZ )|p L =1,2,...,P L ;p M =1,2,...,P M ;p Z =1,2,...,P Z}

[0266] Among them, P L , P M , P Z are all positive integers, and P L , P M , P Z Different values ​​may be taken to represent different values ​​of L, M, and Z. That is, the sequences of different ZCZ sequence sets may have different code lengths L, different numbers of sequences M, or different zero cross-correlation region lengths Z. At least one ZCZ sequence set in the set is used for MIMO-OFDM system perception signal configuration.

[0267] The network may also predefine a list of different combinations of configuration parameters for at least one of an m-sequence, a ZC sequence, a Walsh sequence, and a Hadamard matrix for generating a ZCZ sequence, and a list index corresponding to each combination. The network indicates the ZCZ configuration parameter list index to any at least one of the perception signal sending device and the perception signal receiving device, and the latter determines the specific value of the configuration parameter by looking up a table.

[0268] Optionally, the first ZCZ sequence related information corresponds to at least one ZCZ sequence, the at least one ZCZ sequence includes a first ZCZ sequence, and the first ZCZ sequence can be mapped to the frequency domain using DFT, or the first ZCZ sequence is directly mapped to the time domain.

[0269] The ZCZ sequence is a symbol sequence (such as a binary or complex sequence), and each element of the symbol sequence can be mapped to the frequency domain (or directly to the time domain) through DFT. In the case of mapping to the frequency domain through DFT, the ZCZ sequence can be mapped to the frequency domain by performing DFT transformation on the sequence in the OFDM system. In other words, after determining the ZCZ sequence, it is subjected to DFT, and each element of the obtained sequence is the symbol carried on different OFDM subcarriers. After determining each element on each subcarrier, the sequence can be sent out in the form of a time domain signal through IDFT.

[0270] For example, when the first ZCZ sequence is mapped to the frequency domain using DFT, each element of the first ZCZ sequence may occupy continuous REs, or may be arranged at equal or unequal intervals within the available bandwidth. For another example, when the first ZCZ sequence is directly mapped to the time domain, if each element of the first ZCZ sequence is mapped on different REs in the time domain, each element of the first ZCZ sequence may be arranged at equal or unequal intervals at different times (OFDM symbols).

[0271] Optionally, the at least one ZCZ sequence includes a second ZCZ sequence and a third ZCZ sequence;

[0272] The second ZCZ sequence and the third ZCZ sequence are ZCZ sequences selected from a set of predefined ZCZ sequence sets, and this method is a case where different ZCZ sequences are determined based on a table lookup method;

[0273] or,

[0274] The second ZCZ sequence and the third ZCZ sequence are ZCZ sequences determined based on different base sequences. This method is a case where different ZCZ sequences are determined based on different base sequences.

[0275] or,

[0276] The second ZCZ sequence and the third ZCZ sequence are ZCZ sequences determined based on different base sequence parameters, and this method is a case where different ZCZ sequences are determined based on different base sequence parameters;

[0277] or,

[0278] The third ZCZ sequence is a ZCZ sequence obtained by performing a first operation on the second ZCZ sequence, wherein the second ZCZ sequence is located before the third ZCZ sequence in the time domain, and the first operation is an operation of performing phase rotation on each element of the second ZCZ sequence according to a preset rule. Here, the operation of performing phase rotation on each element of a certain ZCZ sequence according to a preset rule refers to the operation of performing phase rotation on a certain ZCZ sequence as a whole according to a predetermined rule, that is, a uniform phase rotation is performed on each element of a certain ZCZ sequence. The second ZCZ sequence can be the ZCZ sequence of the first moment (OFDM symbol) in the time domain, and other ZCZ sequences can be obtained by performing a phase rotation operation on the second ZCZ sequence at different moments, so as to realize the transmission of different ZCZ sequences at different moments in the time domain.

[0279] For example, the process of performing a first operation on the second ZCZ sequence to obtain a third ZCZ sequence may be, for the second ZCZ sequence of at least one transmitting antenna port, using a preset pseudo-random sequence to determine the rotation angle of the phase rotation, and then performing a phase rotation operation on the second ZCZ sequence at the determined phase rotation angle to obtain a third ZCZ sequence. When the number of transmitting antenna ports is greater than 1, the second ZCZ sequences of different transmitting antenna ports may be different, and the pseudo-random sequences used for the phase rotation operation may also be different. The pseudo-random sequence includes a ZC sequence and an m sequence.

[0280] For example, the process of performing the first operation on the second ZCZ sequence to obtain the third ZCZ sequence may also be, for the second ZCZ sequence of at least one transmit antenna port, using a preset phase rotation step to perform a phase rotation operation on the second ZCZ sequence, thereby obtaining a third ZCZ sequence. When the number of transmit antenna ports is greater than 1, the second ZCZ sequences of different transmit antenna ports may be different, and the phase rotation step used for the phase rotation operation may also be different. The phase rotation step refers to the phase difference between ZCZ sequences at different transmission times.

[0281] When a ZCZ sequence set is used to configure at least two transmit antenna ports, at least two different transmit antenna ports may be configured with different m-sequence shift register initial values, m-sequence primitive polynomials, ZC sequence cyclic shift values, ZC sequence root numbers, Walsh code indexes, Hadamard matrix column indexes, and at least one of Hadamard matrix row indexes.

[0282] Optionally, the first device is a perception signal sending device, and the first device includes at least two transmitting antenna ports;

[0283] The time-frequency resources of the ZCZ sequences used by the at least two transmitting antenna ports overlap, and different transmitting antenna ports use different ZCZ sequences in the same ZCZ sequence set.

[0284] In this method, if the time-frequency resources of the ZCZ sequences of different transmit antenna ports overlap, different transmit antenna ports are required to use different ZCZ sequences, and these ZCZ sequences belong to the same ZCZ sequence set. This ensures that, in the case of multiple transmit antenna ports, the zero cross-correlation characteristics between the ZCZ sequences can achieve signal orthogonality between the transmit antenna ports, so as to ensure that the cross-correlation of different transmit antenna ports in area Z is zero.

[0285] Optionally, the first device is a perception signal sending device, and the first device includes at least two transmitting antenna ports;

[0286] The ZCZ sequences used by the at least two transmitting antenna ports are the same, and time-frequency resources mapped by the ZCZ sequences used by different transmitting antenna ports do not overlap with each other.

[0287] In this method, when the same ZCZ sequence is configured for different transmitting antenna ports, and the same ZCZ sequence of different transmitting antenna ports is mapped to non-overlapping time or frequency resources, signal orthogonality between different transmitting antenna ports can be achieved through time division multiplexing (Time Division Multiplexing, TDM) or frequency division multiplexing (Frequency Division Multiplex, FDM) to ensure that the cross-correlation of different transmitting antenna ports in area Z is zero.

[0288] Optionally, the first device is a perception signal sending device, and the first device includes at least two transmitting antenna ports;

[0289] The ZCZ sequences used by the at least two transmitting antenna ports are the same, and the time-frequency resources mapped by the ZCZ sequences used by different transmitting antenna ports completely overlap. The ZCZ sequences used by different transmitting antenna ports are ZCZ sequences obtained by performing phase rotation operations according to different rules.

[0290] In this method, for different transmit antenna ports configured with the same ZCZ sequence, and the time-frequency resources occupied by the ZCZ sequences used by different transmit antenna ports completely overlap, the ZCZ sequences used by different transmit antenna ports can be obtained by performing different phase rotation operations on a certain ZCZ sequence, so that the resources used by different transmit antenna ports do not overlap in the Doppler domain. In this case, multiple ZCZ sequences need to be configured in the time domain, and the ZCZ sequences used by different transmit antenna ports need to be mapped to the frequency domain through DFT.

[0291] Optionally, the method further comprises:

[0292] The first device uses a second time-frequency resource to transmit a second signal, the second signal is a signal related to a communication service, and the second time-frequency resource is a time-frequency resource within the time-frequency resource range required for synaesthesia of the second device, excluding the first time-frequency resource. That is, in the synaesthesia integration scenario, within the time-frequency resource range required for synaesthesia, other OFDM time-frequency resource positions except the time-frequency resource occupied by the ZCZ sequence can be placed with the second signal, and the second signal can be, for example, a data symbol.

[0293] Optionally, the transmission power of the first signal is higher than the transmission power of the second signal. That is, the first device may perform power boosting on the time-frequency resource where the ZCZ sequence is located.

[0294] Optionally, after the first device determines first ZCZ sequence related information based on the first information, the method further includes:

[0295] The first device acquires second information;

[0296] The second device updates the first ZCZ sequence related information to second ZCZ sequence related information based on the second information;

[0297] The second information includes at least one of the following:
