[0060] In the following, in combination with the accompanying drawings, a signal scrambling method, a perception measurement method, an apparatus and a device provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0061] Please refer to FIG3 , which is a flowchart of a signal scrambling method provided in an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0062] Step 301: A first device generates a scrambling sequence, where the scrambling sequence is associated with perceptual feature information.

[0063] The first device may be a terminal or a network-side device.

[0064] The generating of the scrambling sequence may be generating the scrambling sequence according to the perceptual feature information, so that the scrambling sequence is associated with the perceptual feature information.

[0065] The association between the above-mentioned scrambling sequence and the perceptual feature information can be understood as the above-mentioned scrambling sequence implicitly or explicitly carrying the above-mentioned perceptual feature information, or the association between the above-mentioned scrambling sequence and the perceptual feature information can be understood as the existence of a corresponding relationship between the above-mentioned scrambling sequence and the above-mentioned perceptual feature information, and the corresponding relationship can be a protocol agreement or a network side configuration.

[0066] The above-mentioned perception feature information may include feature information associated with perception, such as information related to perception measurement or information on characteristics of perception services.

[0067] Step 302: The first device scrambles the first signal in the time domain and the frequency domain based on the scrambling sequence to obtain a second signal for perception measurement.

[0068] The first signal mentioned above may be one or more signals.

[0069] The scrambling of the first signal in the time domain and the frequency domain based on the scrambling sequence refers to scrambling in both the time domain and the frequency domain based on the scrambling sequence. This provides the second signal with better anti-interference performance in the time domain and the frequency domain, that is, reduces interference from other signals on the second signal in the time domain and the frequency domain, thereby improving the transmission reliability of the second signal.

[0070] The above-mentioned second signal for perception measurement can be understood as the second signal being at least used for perception measurement. In some embodiments, in addition to being used for perception measurement, the above-mentioned second signal can also be used to transmit communication information, wherein the communication information can be understood as communication data, or the communication information includes communication data.

[0071] In an embodiment of the present application, since the first signal is scrambled in the time domain and frequency domain dimensions, the second signal has better anti-interference performance in the time domain and frequency domain dimensions, that is, the interference of other signals on the second signal is reduced in the time domain and frequency domain dimensions to improve the transmission reliability of the second signal, thereby improving the perceptual performance associated with the second signal. In addition, since the scrambling sequence is associated with the perceptual feature information, the perceptual characteristics of the second signal can be increased, thereby improving the perceptual performance associated with the second signal. In addition, since the first signal is scrambled in the time domain and frequency domain dimensions, the time-frequency domain autocorrelation and cross-correlation characteristics of the first signal can be improved, and the sidelobes of the perceptual measurement can be reduced to improve the perceptual performance.

[0072] As an optional implementation manner, the perceptual feature information includes at least one of the following:

[0073] Perception measurement information, resource information related to perception, perception requirement information, antenna port information of the second signal, and codeword information of the second signal.

[0074] The above-mentioned perception measurement information may refer to information associated with perception measurement.

[0075] In some embodiments, the above-mentioned perception measurement information includes at least one of the following:

[0076] A perception area identifier, a perception service identifier, a perception service type identifier, an identifier for indicating that the second signal is used for perception measurement, a perception target identifier, the number of perception targets, perception measurement amount information, and information of devices participating in the perception measurement.

[0077] The above-mentioned perception area identifier may be an identifier of a target area to be perceived.

[0078] In the embodiment of the present application, the sensing area may be divided in advance, for example, by using at least one of the following methods:

[0079] Method 1: Multiple base station coverage areas (or cells) form a sensing area, and are associated with a sensing area identifier (denoted as n areaID As shown in Figure 4, each hexagonal area represents a base station coverage area, and areas with the same number represent the same perception area. Alternatively, a RAN-based notification area (RNA) can be used as a perception area, and the RNA ID can be used as the perception area identifier.

[0080] Method 2: A single base station coverage area (or 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 recorded as n.areaID ,As shown in Figure 5, the dotted line represents the base station ,coverage area, and each square represents the divided sensing area.

[0081] Method 3: Directly use the geographical area identifiers such as latitude and longitude or coordinate positions that are irrelevant to the location of the base station to generate the perception area identifier n areaID .

[0082] Method 4: Different angle ranges relative to the base station are associated with different sensing area IDn areaID For example, the azimuth angle x1°~x2° and the pitch angle y1°~y2° correspond to the sensing area ID1.

[0083] Since the scrambling sequence is associated with the perception area identifier, this can achieve interference randomization between different perception areas, so as to be applicable to various application scenarios and improve perception performance.

[0084] The above-mentioned perception service identifier can be a specific perception service identifier, for example: different perception services correspond to different perception services n sensingID In this embodiment of the present application, the sensing service may include at least one of the following:

[0085] Detection of target presence, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, Radar Cross Section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, population statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.

[0086] Since the scrambling sequence is associated with the perception service identifier, this can achieve interference randomization between different perception services, so as to be applicable to various application scenarios and improve perception performance.

[0087] The above-mentioned perception service type identifier is the type identifier of the perception service, wherein different types correspond to different perception service types n sensingID .

[0088] For example, the sensing functions or business types can be divided into the following types according to their scope:

[0089] Category 1 (close distance / small range): material analysis, component analysis, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiratory monitoring, heart rate monitoring, pulse monitoring, etc.

[0090] Category 2 (medium distance / medium range): intrusion detection, population counting, indoor positioning, etc.

[0091] Category 3 (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.

[0092] Other classification standards can also be used, such as classification based on function into positioning perception, imaging perception, pattern recognition perception, etc.; classification based on power consumption / energy consumption, classification based on resource occupancy, etc.

[0093] Alternatively, the perception signal may be generated according to the measurement quantity identifier, that is, at least one of the perception measurement quantities is associated with a measurement quantity identifier, as shown in Table 2 below:

[0094] Table 2

[0095] Since the scrambling sequence is associated with the perception service type identifier, interference randomization between different perception service types can be achieved to adapt to various application scenarios and improve perception performance.

[0096] The flag for indicating that the second signal is used for sensing measurement may be 1 bit, for example, when it is not used for sensing, n sensingID = 0, when used for perception n sensingID =1.

[0097] It should be noted that, in some implementations, the second signal may be used for perception measurement by default.

[0098] The above-mentioned perception target identifier may be the identifier of the perception target itself, or may be the identifier of a tag associated with the perception target, or may be the identifier of the perception target type.

[0099] For example: the first device obtains the identification of the sensing target, and different sensing targets correspond to different sensing target identifications (n targetID ), wherein the perception target can be determined based on a priori information obtained from existing measurement results. For example: the network-side device sends a perception measurement signal through an omnidirectional beam to perform preliminary measurement, the network-side device obtains a distance-Doppler map (or a distance-angle map, etc.), determines the number of targets based on the distance-Doppler map, and assigns an ID to each target; or, the network-side device sends a perception measurement signal through an omnidirectional beam to perform preliminary measurement, the 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 based on the distance-Doppler map, and assigns an ID to each target, and then notifies the sending base station of the target ID and / or target-related information.

[0100] For another example, after the first device determines the ID of each target, it generates signals for sensing different targets according to different target IDs, and these sensing signals are sent using different beams, with the beam direction pointing to the sensing target associated with the target ID;

[0101] For another example, the sensing target is equipped with a tag, and different tags are associated with different tag IDs. The first device obtains the tag ID of the corresponding target and then obtains the signal used to sense the 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 can be the tag itself. The sensing identifier can also be a terminal, that is, a common transceiver module is installed on the sensing target, such as a communication device installed in a car, such as an in-vehicle terminal.

[0102] Another example: the identification of the perception target type, different types correspond to different perception target IDs, such as static 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 .

[0103] Since the scrambling sequence is associated with the perception target identifier, this can achieve interference randomization between different perception target identifiers, so as to be applicable to various application scenarios and improve perception performance.

[0104] The above-mentioned number of perception targets is the number of targets to be perceived, so that different scrambling can be performed for scenarios with different numbers of perception targets, so as to be applicable to various application scenarios and improve perception performance.

[0105] The above-mentioned perception measurement quantity information is related information of the perception measurement quantity, which is used to indicate the perception measurement quantity. For example, the above-mentioned perception measurement quantity information may be related information of the perception measurement quantity, such as an identifier of the perception measurement quantity or type information of the perception measurement quantity. In this embodiment of the present application, the perception measurement quantity can be divided into the following types:

[0106] The first-level measurement quantity (also known as the received signal / original channel information) includes at least one of the following:

[0107] Received signal / channel response complex results, amplitude / phase, I-path / Q-path and related operation results (operations including addition, subtraction, multiplication, and division, matrix addition, subtraction, multiplication, and division, matrix transposition, trigonometric operations, square root operations, and power operations, as well as threshold detection results and maximum / minimum value extraction results of the above operation results; wherein, operations also include Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT) / Inverse Discrete Fourier Transform (IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform, and digital filtering, as well as threshold detection results and maximum / minimum value extraction results of the above operation results);

[0108] The second-level measurement quantity (also called basic measurement quantity) includes at least one of the following: time delay, Doppler, angle, intensity, and their multi-dimensional combination representation;

[0109] The third level of measurement (also known as basic attributes / states) includes at least one of the following: distance, speed, direction, spatial position, acceleration;

[0110] The fourth level of measurement (also known as advanced attributes / states) includes at least one of the following: target presence, trajectory, movement, expression, vital signs, quantity, imaging results, weather, air quality, shape, material, and composition.

[0111] Since the scrambling sequence is associated with the perception measurement quantity information, interference randomization between different perception measurement quantities can be achieved, so as to be applicable to various application scenarios and improve perception performance.

[0112] The above-mentioned device information participating in the perception measurement may be a device identifier participating in the perception measurement, for example, a cell identifier or a terminal identifier of the device participating in the perception measurement, such as a Radio Network Temporary Identifier (RNTI).

[0113] Since the scrambling sequence is associated with the information of the devices participating in the sensing measurement, the transmission of the second signal can be made more reliable.

[0114] In some embodiments, the above-mentioned perception-related resource information may be the resource information occupied by the above-mentioned second signal, or may be the information of at least one resource selected by the first device, where the resource at least includes part of the resources occupied by the second signal.

[0115] Optionally, the perception-related resource information includes at least one of the following:

[0116] Information on time domain resources, frequency domain resources, and resource blocks;

[0117] The time domain resources at least include part of the time domain resources occupied by the second signal;

[0118] The frequency domain resources include at least part of the frequency domain resources occupied by the second signal;

[0119] The resource block includes at least a portion of the resource block occupied by the second signal.

[0120] The above at least includes can be understood as including part of the resources occupied by the second signal, or including all the resources occupied by the second signal, and also including or excluding other resources.

[0121] In some embodiments, the above-mentioned time domain resource information includes information related to the time domain resources, such as at least one of the following: wireless frame index, subframe index, time slot index, symbol index, duration, time domain density, cyclic prefix (CP) type, CP length, coherent processing time window index, and number of coherent processing time windows.

[0122] For example, the time domain resource information may be the index corresponding to the first time slot occupied by the second signal within the current coherent processing time window, or the index corresponding to the first symbol, or the coherent processing time window index, or the number of coherent processing time windows. The coherent processing time window is the time window for each calculation and output of the perception measurement result, such as the time domain resource length corresponding to the range-Doppler map obtained by performing a two-dimensional FFT operation. The window may include multiple time slots or symbols.

[0123] In some implementations, the frequency domain resource information may include resource element (RE) index, resource block (RB) index, frequency point information, frequency band information, bandwidth, frequency domain density, and subcarrier spacing).

[0124] In some embodiments, the resource block information may be a perception resource block index, where the perception resource block includes multiple physical resource blocks (PRBs) and multiple time slots / symbols, i.e., includes specific time-frequency domain resources, such as performing a two-dimensional FFT operation to obtain the frequency domain resource length and time domain resource length corresponding to the range-Doppler map.

[0125] Since the perception feature information includes perception-related resource information, the scrambling of the second signal can be associated with the perception-related resources to improve the transmission reliability of the second signal.

[0126] In some embodiments, the aforementioned perceived requirement information may be perceived configuration requirements or perceived performance requirements.

[0127] Optionally, the perception demand information includes at least one of the following:

[0128] Perceive performance requirement information and resource configuration requirement information.

[0129] The above-mentioned perceived performance requirement information may include at least one of the following:

[0130] Delay resolution requirements, distance resolution requirements, Doppler resolution requirements, speed resolution requirements, delay measurement range requirements, distance measurement range requirements, Doppler measurement range requirements, speed measurement range requirements.

[0131] The above-mentioned perception resource configuration requirement information may be a perception signal resource configuration requirement, for example: perception signal frequency domain resource length (such as bandwidth, number of REs or number of RBs), frequency domain resource interval or density, time domain resource length (such as coherent processing time, number of symbols, number of time slots or number of radio frames), time domain resource interval or density. The above-mentioned perception signal is the above-mentioned second signal. In addition, the above-mentioned perception resource configuration requirement information may be a perception resource configuration requirement for the first device to send the second signal.

[0132] Since the scrambling sequence is associated with the perception requirement information, this can achieve interference randomization for different perception requirements, so as to be applicable to various application scenarios and improve perception performance.

[0133] In some embodiments, the antenna port information of the second signal includes at least one of the following:

[0134] The port index of the second signal, the antenna index of the second signal, and the maximum number of ports of the second signal.

[0135] Since the scrambling sequence is associated with the antenna port information, this can achieve interference randomization between different antenna port information, so as to be applicable to various application scenarios and improve perception performance.

[0136] The codeword information of the second signal may be a codeword index of the second signal, specifically a codeword index of the first signal.

[0137] Since the scrambling sequence is associated with the codeword information, this can achieve interference randomization between different codewords, so as to be applicable to various application scenarios and improve perception performance.

[0138] In some embodiments, the above-mentioned perceptual feature information is perceptual feature information that enables the second signal to meet the measurement performance of basic perceptual measurement quantities such as delay / distance, Doppler / speed, or angle, that is, the second signal for perceptual measurement is generated based on the perceptual feature information, which can meet the measurement performance of basic perceptual measurement quantities such as delay / distance, Doppler / speed, and angle. For example, for an orthogonal frequency division multiplex (OFDM) system, the data content carried by different time-frequency resource units is associated with the perceptual performance, that is, the corresponding autocorrelation characteristics and cross-correlation characteristics of the sequence along the time domain dimension or the frequency domain dimension will affect the perceptual performance. In this way, the original signal characteristics can be improved by scrambling the time-frequency domain sequence (scrambling the time domain dimension and the frequency domain dimension), so that the interference between signals for communication and perception, different perceptual services, different perceptual areas, different perceptual targets, etc. is randomized, which can be applied to various perceptual application scenarios and improve perceptual performance.

[0139] As an optional implementation manner, the scrambling sequence is a sequence generated based on the target sequence, and the association between the scrambling sequence and the perceptual feature information includes at least one of the following:

[0140] The target sequence is associated with the perceptual feature information;

[0141] The length of the scrambling sequence is associated with the perceptual characteristic information.

[0142] The target sequence may be a sequence agreed upon in a protocol or indicated by a network side. For example, the target sequence may include at least one of the following:

[0143] Pseudo Random (PN) sequence, ZC (Zadoff-Chu) sequence, Chirp sequence (also called Chirp signal).

[0144] The PN sequence includes but is not limited to at least one of the following:

[0145] Gold sequence, phase control (PC) sequence, shift register sequence (such as m and M sequence), GMW sequence, cascaded GMW sequence Kasami sequence, Bent sequence, No sequence.

[0146] In some implementations, the scrambling sequence may be a scrambling sequence obtained by performing Quadrature Phase Shift Keying (QPSK) modulation on a PN sequence.

[0147] It should be noted that the embodiment of the present application does not limit the method for generating the scrambling sequence. For example, the scrambling sequence can be generated using a method defined in the protocol, or a scrambling sequence generation method newly defined in a subsequent protocol version can be used.

[0148] In some implementations, the scrambling sequence may also be a scrambling sequence generated based on at least one of the following:

[0149] Frequency Modulated Continuous Wave (FMCW) signal, Golay sequence, complementary Golay sequence, complementary code, Frank code, P code, Barker code, Const Amplitude Zero Auto-Correlation (CAZAC) sequence, Low Ambiguity Zone (LAZ) code, Zero Ambiguity Zone (ZAZ) code, JPL sequence, Walsh-Hadamard code.

[0150] The above-mentioned P code is a P code defined in the protocol, such as: P1 code, P2 code, P3 code or P4 code, or expressed as P1-P2-P3-P4 code.

[0151] Optionally, the association between the target sequence and the perceptual feature information includes at least one of the following:

[0158] The starting frequency of the target sequence is associated with the perceptual feature information.

[0159] The above-mentioned at least one item can be understood as at least one of the following items being associated with the above-mentioned perceptual feature information:

[0160] Initial value, primitive polynomial, cyclic shift value, intercept position, root sequence number, frequency modulation slope, and start frequency.

[0161] The at least one item being associated with the perceptual feature information may be that the at least one item is determined based on the perceptual feature information.

[0162] In some embodiments, when the target sequence is a PN sequence, an initial value, a primitive polynomial, a cyclic shift value, or a truncation position of the PN sequence is associated with the perceptual feature information;

[0163] In some embodiments, when the target sequence is a ZC sequence, a root sequence number or a cyclic shift value of the ZC sequence is associated with the perceptual feature information;

[0164] In some embodiments, when the target sequence is a Chirp sequence, the frequency modulation slope or starting frequency of the Chirp sequence is associated with the perceptual feature information.

[0165] Since the target sequence is associated with the perceptual feature information, the transmission of the second signal is more reliable and the second signal can be associated with more perceptual feature information, thereby improving the perceptual performance of perceptual measurement based on the second signal.

[0166] The length of the scrambling sequence may also be understood as the number of elements in the scrambling sequence.

[0167] The association between the length of the above-mentioned scrambling sequence and the perceptual characteristic information may be that the length of the scrambling sequence is associated with the perceptual requirement information, for example: the length of the scrambling sequence is associated with the perceptual performance requirement information or the perceptual resource configuration requirement information, that is, the length of the scrambling sequence or the number of elements corresponds to the number of perceptual signal resources to meet the perceptual performance requirements.

[0168] The association between the length of the scrambling sequence and the sensing performance requirement information or the sensing resource configuration requirement information may include at least one of the following:

[0169] The perceived delay / distance resolution is associated with the length of the perceived signal frequency domain resources, the perceived Doppler / velocity resolution is associated with the length of the perceived signal time domain resources, the perceived delay / distance unambiguous range is associated with the interval or density of the perceived signal frequency domain resources, and the perceived Doppler / velocity unambiguous range is associated with the interval or density of the perceived signal time domain resources.

[0170] Since the length of the target sequence is associated with the perceptual feature information, the second signal is more closely matched with the perceptual feature information, thereby improving the perceptual performance of perceptual measurement based on the second signal.

[0171] As an optional implementation manner, the scrambling sequence includes: a first scrambling sequence and a second scrambling sequence; or, the scrambling sequence includes: a third scrambling sequence;

[0172] The first device scrambles the first signal in a time domain dimension and a frequency domain dimension based on the scrambling sequence, including:

[0173] The first device performs frequency domain scrambling on the first signal based on the first scrambling sequence, and the first device performs time domain scrambling on the first signal based on the second scrambling sequence;

[0174] or,

[0175] The first device scrambles the first signal in time domain and frequency domain dimensions based on the third scrambling sequence.

[0176] The perceptual feature information associated with the first scrambling sequence, the second scrambling sequence, and the third scrambling sequence is the same or different, and the first scrambling sequence, the second scrambling sequence, and the third scrambling sequence can be generated based on the same or different sequences or codes, and the generation methods of the first scrambling sequence, the second scrambling sequence, and the third scrambling sequence can be the same or different.

[0177] Optionally, the sequence length of the first scrambling sequence matches the number of frequency domain resources occupied by the second signal;

[0178] The sequence length of the second scrambling sequence matches the number of time domain resources occupied by the second signal;

[0179] The sequence length of the third scrambling sequence is equal to the product of the number of time domain resources and the number of frequency domain resources occupied by the second signal.

[0180] The matching of the sequence length of the first scrambling sequence with the number of frequency domain resources occupied by the second signal may be that the sequence length of the first scrambling sequence matches the number of subcarriers occupied by the second signal, or the sequence length of the first scrambling sequence is associated with the frequency domain resource length and frequency domain interval of the second signal. For example: the first scrambling sequence length N is determined based on the number of subcarriers occupied by the second signal (associated with the frequency domain resource length and frequency domain interval of the perception signal), and the first scrambling sequence can be expressed as x = [x(0), x(1), ..., x(N-1)] T , where N is an integer greater than or equal to 1.

[0181] The matching of the sequence length of the second scrambling sequence with the number of time domain resources occupied by the second signal may be that the sequence length of the second scrambling sequence matches the number of time domain symbols occupied by the second signal. If the second scrambling sequence length M is determined based on the number of time domain symbols occupied by the second signal (associated with the time domain resource length and time domain interval of the perception signal), the second scrambling sequence can be expressed as y=[y(0), y(1),…, y(M-1)], where M is an integer greater than or equal to 1.

[0182] In some implementations, the above matches may be identical.

[0183] The sequence length of the above-mentioned third scrambling sequence can be expressed as M*N, where N can be expressed as the number of frequency domain dimension resource units of the signal to be scrambled (such as the second signal). The number of time domain dimension resource units of the signal to be scrambled (such as the second signal) is determined. The third scrambling sequence can be expressed as x=[x(0),x(1),…,x(MN-1)].

[0184] In the above implementation, scrambling can be performed separately in the time domain and the frequency domain, or overall scrambling can be performed in the time and frequency domain dimensions, so as to improve the flexibility of scrambling and meet the needs of more scenarios or services.

[0185] In some implementations, the lengths of the first scrambling sequence, the second scrambling sequence, and the third scrambling sequence may also be determined by protocol agreement or configured on the network side, which is not limited.

[0186] As an optional implementation manner, when the second signal is a multi-port signal:

[0187] The multi-port signal includes port signals occupying different frequency domain resources, or the multi-port signal includes port signals occupying different time domain resources, or the multi-port signal includes port signals with different scrambling sequences.

[0188] The port signals with different occupied frequency domain resources in the multi-port signals may be different frequency domain resources occupied by different port signals, or different frequency domain resources occupied by some port signals, for example, different port signals correspond to different frequency domain resources of the scrambled first signal.

[0189] The port signals occupying different time domain resources in the multi-port signals may be different time domain resources occupied by different port signals, or different time domain resources occupied by some port signals, for example, different port signals correspond to different time domain resources of the scrambled first signal.

[0190] The multi-port signals include port signals with different scrambling sequences. Different port signals may be scrambled using different scrambling sequences, or some port signals may be scrambled using different scrambling sequences.

[0191] In the above implementation, the second signal can be frequency-division multiplexing, time-division multiplexing, or code-division multiplexing to reduce signal interference between different ports or users. For example, in a multi-port / multi-user scenario, code-division multiplexing can be performed by scrambling to reduce signal interference between different ports or users.

[0192] In some implementations, the second signal is a single-port signal.

[0261] The dedicated perception signal may be a perception signal generated based on a Chirp or FMCW signal, or a perception signal generated based on a PN sequence, a pseudo-random sequence, or the like.

[0262] In the above implementation, at least one of a signal carrying communication information, a reference signal, a synchronization signal, and a dedicated perception signal can be scrambled to obtain a second signal for perception measurement, thereby increasing the flexibility of perception measurement. Furthermore, because the second signal for perception measurement is obtained by multiplexing an existing reference signal or a signal carrying communication information in the communication system, resource overhead can be reduced.

[0263] As an optional implementation manner, the first device scrambles the first signal in the time domain and the frequency domain based on the scrambling sequence, including:

It refers to a network node in the core network or RAN responsible for at least one function, such as perception request processing, perception resource scheduling, perception information interaction, and perception data processing.

Specifically, the functional characteristics of the perception network function / perception network element may include at least one of the following:

[0297] In an embodiment of the present application, a first device generates a scrambling sequence, and the scrambling sequence is associated with perceptual feature information; the first device scrambles the first signal in the time domain and frequency domain dimensions based on the scrambling sequence to obtain a second signal for perceptual measurement. In this way, since the first signal is scrambled in the time domain and frequency domain dimensions, the second signal has better anti-interference performance in the time domain and frequency domain dimensions, that is, the interference of other signals on the second signal is reduced in the time domain and frequency domain dimensions, so as to improve the transmission reliability of the second signal, thereby improving the perceptual performance associated with the second signal.

[0359] It should be noted that this embodiment is an implementation of the second device corresponding to the embodiment shown in Figure 3. Its specific implementation can refer to the relevant description of the embodiment shown in Figure 3. In order to avoid repeated description, this embodiment will not be repeated.

[0360] The following describes the method provided in the embodiments of the present application through multiple examples:

[0361] Example 1:

[0362] This embodiment mainly describes the generation of a scrambling sequence, which is specifically as follows:

[0363] This embodiment provides a method for generating a first scrambling sequence, a second scrambling sequence, and a third scrambling sequence. In this embodiment, scrambling may be generated based on a PN sequence (generating a binary sequence and then performing QPSK modulation to obtain the scrambling sequence, or directly using a binary sequence (sequence elements consisting of ±1) as the scrambling sequence). The initial value of the PN sequence, or the primitive polynomial of the PN sequence, or the cyclic shift value of the PN sequence, or the truncation position of the PN sequence is associated with perceptual feature information. Taking the Gold sequence and QPSK modulation as an example, the scrambling sequence may be generated by:

[0364] Generate the PN sequence according to the following formula: c(n) = (x1(n+N C )+x2(n+N C ))mod2 x1(n+31)=(x1(n+3)+x1(n))mod2 x2(n+31)=(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2

[0365] Where n = 0, 1, ..., M PN -1,M PN is the sequence length, N C= 1600, the initialization method of the first m-sequence x1(n) is x1(0) = 1, x1(n) = 0, n = 1, 2, ..., 30; the initialization method of the second m-sequence x2(n) is

[0366] In some embodiments, the PN sequence is modulated to obtain the first scrambling sequence or the second scrambling sequence, for example, QPSK modulation is performed: 0 ≤ n < M, where M is the length of the first scrambling sequence or the second scrambling sequence, and c(2n) and c(2n + 1) are when n in the above formula c(n) is expressed as 2n or 2n + 1.

[0367] Alternatively, according to the initial value c init generate a pseudo-random sequence, and generate a sequence through π / 2-BPSK modulation according to the pseudo-random sequence c(i) where c(i) is when n in the formula c(n) is expressed as i, and then according to the sequence generate a base sequence: Then generate the first scrambling sequence / second scrambling sequence according to the base sequence: 0 ≤ n < M, where M is the length of the first scrambling sequence / second scrambling sequence. The first scrambling sequence / second scrambling sequence generated by this method has a smaller Peak to Average Power Ratio (PAPR) compared to the previous method, has a higher power amplifier efficiency, and is beneficial to improving the sensing measurement coverage performance.

[0368] Among them, the above-mentioned sensing feature information can be referred to the corresponding description of the embodiment shown in Figure 3, which will not be elaborated here.

[0369] Specifically, taking the sensing area identifier n areaID as an example, the initial value of the PN sequence can be:

[0370] c init = n areaID , where n areaID is the sensing area identifier; or,

[0371] or or or where is the number of symbols in each time slot, is the time slot index within the radio frame, l is the symbol index within the time slot, n areaID is the sensing area identifier, and x is a non-negative integer.

[0372] Among them, the coefficient parameter of the first term in the initialization formula can be determined according to the variable value range and the value of the coefficient parameter of the following terms. For example, if there are 1000 perception area IDs in total and they need to be represented by 10-bit binary numbers, then x=10 can be set to ensure that no repeated generation sequence occurs. Where A is a non-negative positive integer, and A=31 can be set.

[0373] or, or in is the physical cell identifier, or or Where x and y are non-negative positive integers.

[0374] Or, c init =(2 x n RNTI +n areaID )mod2 A or c init =2 x n RNTI +n areaID , where n RNTI is the terminal identifier, where x and A are non-negative positive integers, and A can be set to 31.

[0375] or, or It can also be or Where x, y, and A are non-negative positive integers, and A can be set to 31.

[0376] or, or Where q is the codeword index, which can also be or Where x, y, z, and A are non-negative positive integers, and A can be set to 31.

[0377] Alternatively, taking the sensing area identifier and the sensing target identifier as an example, the initial value of the PN sequence may be: or

[0378] Alternatively, the perceptual coherence processing time window index n period and antenna port index n port For example, the initial value of the PN sequence can be: c init =(2 x (n period +1)+nport )mod2 A or c init =2 x (n period +1)+n port

[0379] or or or or in represents the number of time slots corresponding to each coherent processing time window, The time slot index within the coherent processing time window.

[0380] In some implementations, the scrambling sequence may also be generated based on a ZC sequence. Compared to generating a perception signal based on a PN sequence, the perception signal generated in this manner has a lower peak-to-average power ratio (PAPR) and higher power amplifier efficiency, which is beneficial for improving perception measurement coverage performance. The root sequence number value or cyclic shift value of the ZC sequence is associated with the perception feature information. Specifically, the generation method is:

[0381] Determined by the root sequence number q Then we get the base sequence 0≤n <M,N ZC is the largest prime number less than the sequence length M. Further, the perception signal is obtained by cyclic shift: 0≤n <M。

[0382] The sequence length M is related to the perception signal resource and the scrambling sequence length. For example, the number of frequency domain resource units used to transmit the perception signal, that is, the length of the first scrambling sequence, is determined based on the perception signal bandwidth and the frequency domain resource interval. Alternatively, the number of time domain resource units used to transmit the perception signal, that is, the length of the second scrambling sequence, is determined based on the total duration of the perception signal and the time domain resource interval. Alternatively, the number of time-frequency domain resource units used to transmit the perception signal, that is, the length of the third scrambling sequence, is determined based on the perception signal bandwidth, the frequency domain resource interval, the total duration of the perception signal, and the time domain resource interval.

[0383] Among them, the cyclic shift value α and the root sequence number q are associated with the perception feature information. The association method can be, for example, if the perception area identifier is an 8-bit ID, then all or part of the 8 bits can be used to calculate the root sequence number q or cyclic shift value α of the sequence. For example, the cyclic shift value α can be determined by the first 4 bits of the ID, and the root sequence number q is determined by the last 4 bits of the ID; for another example, the cyclic shift value α is determined according to the perception service identifier, and the root sequence number q is determined according to the perception area identifier. There may be a preset mapping relationship between different perception area identifiers and the root sequence number q, as shown in Table 4 below. The preset mapping relationship is agreed upon or obtained through a signaling message.

[0384] Table 4

[0385] In some implementations, the root sequence number q may be calculated according to a formula. Specifically, the root sequence number q may be calculated as follows:

[0386] Among them, u∈{0,1,...,29} is the group number, v is the base sequence number in the group, and taking the perception area identifier as an example, the value can be u=(n areaID )mod30,v=0.

[0387] In some implementations, the cyclic shift value may be calculated, for example, as follows: is the maximum value in the region identifier.

[0388] In some implementations, a scrambling sequence may be generated based on a chirp or FMCW signal, where the frequency modulation slope of the chirp or FMCW signal is associated with the perceptual characteristic information. FMCW transmits a waveform whose frequency varies over time, typically linearly. A frequency modulation cycle of an FMCW waveform is generally referred to as a chirp, as shown in Figure 7.

[0389] Among them, the Chirp signal can be expressed by the following formula:

[0390] Among them, A0 is the amplitude, f c is the starting frequency, |k|=±B / T is the frequency modulation slope, where B is the bandwidth and T is the chirp duration (ie, the frequency modulation period of FMCW).

[0391] Among them, different frequency modulation slopes are associated with perception feature information. For example, different perception services have different requirements for bandwidth and Chirp duration, that is, different frequency modulation slope requirements. There may be a preset mapping relationship between different perception service IDs and different frequency modulation slopes.

[0392] Different starting frequencies are associated with perception feature information. For example, there is a preset mapping relationship between different perception areas and starting frequencies.

[0393] Example 2:

[0394] This embodiment mainly describes the scrambling method, which is as follows:

[0395] This embodiment specifically describes performing frequency-domain scrambling on the first signal based on the first scrambling sequence, and performing time-domain scrambling on the first signal based on the second scrambling sequence.

[0396] The first scrambling sequence length N is determined based on the number of subcarriers occupied by the second signal (associated with the second signal's frequency domain resource length and frequency domain interval), and the second scrambling sequence length M is determined based on the number of time domain symbols occupied by the second signal (associated with the second signal's time domain resource length and time domain interval). A first scrambling sequence x = [x(0), x(1), ..., x(N-1)] is generated according to the method described in Example 1. T And the second scrambling sequence y = [y(0), y(1), ..., y(M-1)]. It should be noted that the generation methods of the first scrambling sequence and the second scrambling sequence can be different.

[0397] In this embodiment, the resource length and resource interval (or density) meet the perceptual performance requirements, as follows:

[0398] The time-frequency domain resource length is associated with the perception resolution requirement; the time-domain resource length T meets the Doppler / velocity resolution requirement, and the frequency-domain resource length B meets the delay / range resolution requirement. For example, for single-base radar perception:

[0399] The time domain resource length satisfies T≥1 / Δf d Or T≥c / (2f c Δv), where Δf d is the Doppler resolution, Δv is the velocity resolution;

[0400] The frequency domain resource length satisfies B≥1 / Δτ or B≥c / (2ΔR), where Δτ is the delay resolution and ΔR is the distance resolution.

[0401] The time-frequency domain resource spacing (or density) is associated with the sensing measurement range requirements; wherein, the time domain spacing ΔT satisfies the Doppler / velocity unambiguous measurement requirements, and the frequency domain spacing Δf satisfies the delay / distance unambiguous measurement requirements. For example, for single-base radar sensing:

[0402] If the speed direction is considered, the time domain resource interval satisfies ΔT≤1 / (2|f dmax |) or ΔT≤c / (4f c |v max|); If the time domain resource interval in the direction of speed is not considered and satisfies ΔT≤1 / f dmax Or ΔT≤c / (2f c v max ), where f dmax is the maximum unambiguous Doppler, v max is the maximum unambiguous velocity, f c is the carrier frequency, c is the speed of light;

[0403] Frequency domain resource spacing satisfies Δf1≤1 / τ max Or Δf1≤c / (2R max ), where τ max is the maximum unambiguous delay, v max is the maximum unambiguous speed.

[0404] Assume that all signal resources in the first signal are scrambled to obtain the second signal (optionally, part of the signal resources in the first signal may be scrambled to obtain the second signal). The first signal occupies M OFDM symbols and N subcarriers in the time-frequency domain, which is expressed as:

[0405] Scrambling the first signal in the frequency domain based on the first scrambling sequence can be expressed as:

[0406] Scrambling the first signal in the time domain based on the second scrambling sequence can be expressed as:

[0407] The second signal obtained after time-frequency domain scrambling based on the first scrambling sequence and the second scrambling sequence can be expressed as:

[0408] where e jθ is a fixed phase rotation (indicating an overall phase rotation of all elements in the matrix), for example, θ = 0 (equivalent to no additional phase rotation) or

[0409] When multi-port sensing measurement is required, it can be based on scrambling the signals occupying different time-frequency domain resources in the first signal as the second signals corresponding to different antenna ports, that is, using frequency division multiplexing or time division multiplexing to realize multi-port signal transmission. It can also be based on using different first scrambling sequences or second scrambling sequences to scramble the signals occupying the same time-frequency domain resources in the first signal to obtain the second signals corresponding to different antenna ports. If it is generated based on the PN sequence, by using different scrambling code initial values ​​c initDifferentiate; if generated based on the ZC sequence, differentiate by different cyclic shift values and / or root sequence numbers; if generated based on the Chirp signal, differentiate by different frequency modulation slopes and / or starting frequencies. The specific generation method is as described in Embodiment 1, that is, the antenna port index is included in the sensed feature information.

[0410] For example: the sensed signals corresponding to different ports use different first scrambling sequences and different second scrambling sequences, where the first scrambling sequence and the second scrambling sequence are PN sequences, and the initial value corresponding to the first scrambling sequence is:

[0411] or

[0412] or

[0413] or

[0414] The initial value corresponding to the second scrambling sequence is:

[0415] or

[0416] or

[0417] or

[0418] For another example, when using the ZC sequence, it can be that the first scrambling sequence or the second scrambling sequence corresponding to different ports uses the same ZC base sequence, and then obtain the base sequence 0 ≤ n < M, where the root sequence numbers q of different ports are the same. Further, different first scrambling sequences / second scrambling sequences corresponding to different ports are obtained through cyclic shift: 0 ≤ n < M, and the calculation method of the cyclic shift value can be, for example: is the cyclic shift value associated with the port index.

[0419] In addition, when using the ZC sequence, it can also be that the first scrambling sequence / second scrambling sequence corresponding to different ports uses different ZC base sequences, that is, the root sequence numbers are different, where is associated with the port index,

[0420] In addition, when using the ZC sequence, it can also be that the first scrambling sequence / second scrambling sequence corresponding to different ports uses different ZC base sequences and different cyclic shift values, where the root sequence number and the cyclic shift value are associated with the port index.

[0421] For example, in a scenario where multi-target sensing is performed using a QPSK-modulated communication data signal (i.e., the first signal is the communication data signal), if scrambling is not performed and the data signal is directly used for sensing via multiple beams, signals from different beams will interfere with each other, affecting sensing performance. Using the scrambling method described above can effectively reduce interference between sensing signals from different ports and improve sensing performance, as shown in Figure 8.

[0422] Example 3:

[0423] This embodiment mainly describes the scrambling method, which is as follows:

[0424] This embodiment describes a method for performing overall scrambling in the time-frequency domain on the first signal based on the third scrambling sequence.

[0425] The number of frequency domain resource units N of the signal to be scrambled is determined based on the number of subcarriers occupied by the second signal (associated with the frequency domain resource length and frequency domain interval of the second signal), and the number of time domain resource units M of the signal to be scrambled is determined based on the number of time domain symbols occupied by the second signal (associated with the time domain resource length and time domain interval of the second signal), thereby determining the length of the third scrambling sequence M*N. The third scrambling sequence x=[x(0), x(1), ..., x(MN-1)] is generated according to the method described in the first embodiment above.

[0426] Assume that all signal resources in the first signal are scrambled to obtain the second signal (optionally, part of the signal resources in the first signal may be scrambled to obtain the second signal). The first signal occupies M OFDM symbols and N subcarriers in the time-frequency domain, which is expressed as:

[0427] The second signal obtained by scrambling the first signal in the time-frequency domain based on the third scrambling sequence can be expressed as:

[0428] or:

[0429] where e jθ is a fixed phase rotation (indicating an overall phase rotation of all elements in the matrix), for example, θ = 0 (equivalent to no additional phase rotation) or

[0430] When multi-port perception measurement is required, it can be based on scrambling the signals occupying different time-frequency domain resources in the first signal as the second signals corresponding to different antenna ports, that is, using frequency division multiplexing or time division multiplexing to realize multi-port signal transmission. It is also possible to use different third scrambling sequences to scramble the signals occupying the same time-frequency domain resources in the first signal to obtain second signals corresponding to different antenna ports. If generated based on the PN sequence, the different scrambling code initial values ​​cinit are used to distinguish; if generated based on the ZC sequence, the different cyclic shift values ​​and / or root sequence numbers are used to distinguish; if generated based on the Chirp signal, the different frequency modulation slopes and / or starting frequencies are used to distinguish. The specific generation method is as described in Example 1, that is, the perception feature information includes the antenna port index.
