[0056] Before describing the embodiments of the present application, the following briefly introduces communication perception integration / synaesthesia integration:

[0057] Future 5G (Beyond 5G, B5G) and 6G wireless communication systems are expected to provide a variety of high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are typically designed separately and occupy different frequency bands. Integrated Sensing and Communication (ISAC) enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology in future wireless communication systems, supporting many important application scenarios. Typical applications of ISAC include navigation and obstacle avoidance for autonomous vehicles, Wi-Fi-based indoor positioning and activity recognition, communication and sensing for unmanned aerial vehicles, extended reality (XR), and radar and communication integration. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted significant research interest and attention from both academia and industry.

[0058] ISAC achieves low-cost, integrated communication and perception capabilities through shared hardware and software-defined functions. Its key features include: a unified and simplified architecture; reconfigurable and scalable functions; and improved efficiency and reduced costs. The advantages of integrated communication and perception are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0059] At present, typical communication perception integration scenarios that are expected to be achieved through technical upgrades based on the 5G communication system architecture are shown in Table 1.

[0060] Table 1 Typical scenarios of communication and perception integration

[0061] There are six basic sensing methods based on the difference between the sending and receiving nodes of the sensing signal, as shown in Figure 2. They include:

[0062] (1) Base station self-transmitting and self-receiving sensing: In this sensing mode, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.

[0063] (2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0064] (3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement.

[0065] (4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement.

[0066] (5) Terminal self-transmitting and self-receiving perception: Terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0067] (6) Sidelink perception between terminals: Terminal B receives the perception signal sent by terminal A and performs perception measurements.

[0068] It's worth noting that in Figure 2, each sensing method uses a single sensing signal transmitting node and a single sensing signal receiving node as examples. In actual systems, one or more sensing methods can be selected based on different sensing use cases and requirements, and each sensing method can have one or more transmitting and receiving nodes. The sensing targets in Figure 2 use people and vehicles as examples, assuming neither person nor vehicle carries or has installed signal transceiver / receiver equipment. In actual scenarios, the range of sensing targets will be much richer.

[0069] In the related art, spectrum analysis is performed on the channel matrix obtained by processing the perception signal through AD sampling, channel estimation, etc. to obtain the amplitude spectrum, power spectrum or complex spectrum (which can be collectively referred to as spectrum) of a predetermined dimension. This is a necessary process for obtaining the perception measurement quantity (or perception result). In many scenarios, after obtaining the amplitude spectrum, power spectrum or complex spectrum of a predetermined dimension, it is necessary to report the amplitude spectrum, power spectrum or complex spectrum for subsequent processing, or to perform signal detection based on the amplitude spectrum, power spectrum or complex spectrum to obtain information such as the delay, Doppler or angle of the perception target. Since the above-mentioned amplitude spectrum, power spectrum or complex spectrum are directly obtained through spectral analysis operations, these spectra contain clutter interference information. If they are reported directly or subjected to subsequent processing such as signal detection, there are the following disadvantages: first, the amount of data reported is large, resulting in a waste of communication resources; second, it is not conducive to signal detection, and thus is not conducive to the acquisition of perception results.

[0070] In view of this, embodiments of the present application provide an information transmission method, apparatus, and communication device to solve the problem that a spectrum directly obtained through spectrum analysis operation contains clutter interference information, which is not conducive to subsequent processing.

[0071] The information transmission method and information transmission device provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0072] FIG3 shows a flow chart of an information transmission method provided by an embodiment of the present application. As shown in FIG3 , the information transmission method includes the following steps:

[0073] Step 301: A first device acquires first information, where the first information includes at least one of a target spectrum, a target measurement quantity, and target data;

[0074] Step 302: The first device sends the first information to the second device.

[0075] The target spectrum is determined based on a first spectrum and a second spectrum, the first spectrum is a spectrum obtained at a first moment and in a target area through a first signal, the second spectrum is a spectrum obtained at a second moment and in the target area through a second signal, the second moment is before the first moment, and both the first signal and the second signal are signals used for perception.

[0076] The target measurement quantity is determined based on the target spectrum.

[0077] The target data is obtained based on data compression processing performed on the target spectrum.

[0078] The following spectrum is defined in the present embodiment:

[0079] First spectrum: an amplitude spectrum, power spectrum, or complex spectrum obtained by performing spectrum analysis on a channel matrix obtained by performing AD conversion and channel estimation on a received signal of a perception signal at a first moment.

[0080] Second spectrum: an amplitude spectrum, power spectrum, or complex spectrum obtained by performing spectrum analysis on a channel matrix obtained by performing AD conversion and channel estimation on the received signal of the perception signal at the second moment.

[0081] Here, the second time is before the first time. The second time can be a time that is long before the first time, or a time that is relatively close to the first time.

[0082] The spectrum analysis operations here may include Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), Multiple Signal Classification (MUSIC), Estimating Signal Parameter via Rotational Invariance Techniques (ESPRIT) or wavelet transform algorithms. In a typical example, for any port, the time-frequency domain channel matrix obtained by channel estimation is subjected to IFFT operation along the frequency domain dimension and FFT operation along the time domain dimension to obtain a complex spectrum in the delay-Doppler dimension. The complex spectrum, that is, any unit in the delay-Doppler dimension corresponds to a complex value. The amplitude spectrum can be obtained by taking the modulus of the complex value of the complex spectrum, and the power spectrum can be obtained by taking the square of the modulus of the complex value of the complex spectrum.

[0083] In the above example, if the channel estimate is transformed from the time-frequency domain to the delay-Doppler domain using the MUSIC algorithm or the ESPRIT algorithm, the power spectrum is directly obtained. That is, any unit in the delay-Doppler dimension corresponds to a real value, which is the signal power corresponding to that unit.

[0084] The process of obtaining the second spectrum can be exactly the same as the process of obtaining the first spectrum. The difference between the two is that the first spectrum is obtained by transmitting, receiving, and measuring the sensing signal at the time of sensing (i.e., the first moment), while the second spectrum is obtained by transmitting, receiving, and measuring the sensing signal before sensing (i.e., the second moment).

[0085] In other words, the first spectrum is obtained by transmitting, receiving, and measuring sensing signals when a sensing target exists in the target area and sensing measurement is required. The second spectrum is obtained by transmitting, receiving, and measuring sensing signals in advance when no sensing target exists in the target area.

[0086] In other words, the first spectrum is obtained by transmitting, receiving, and measuring the perception signal after the position or velocity of the perceived target in the target area changes, in order to perceive and measure the changed position or velocity of the perceived target. The second spectrum is obtained by transmitting, receiving, and measuring the perception signal before the position or velocity of the perceived target in the target area changes.

[0087] It can be understood that the first spectrum is the spectrum directly obtained through spectral analysis as mentioned in the related art and requires subsequent processing. As can be seen from the above description, the first spectrum contains clutter interference information. The second spectrum is obtained in advance when there is no perceived target in the target area or before the position or velocity of the perceived target changes. Therefore, the second spectrum can be understood as a clutter spectrum.

[0088] Target spectrum: the amplitude spectrum, power spectrum, or complex spectrum obtained based on the first spectrum and the second spectrum.

[0089] The difference between the target spectrum and the first spectrum is that the first spectrum is directly obtained through spectral analysis, while the target spectrum is obtained by adaptively processing the first spectrum using the second spectrum. To a certain extent, the target spectrum can be understood as the spectrum obtained by processing the clutter interference information contained in the first spectrum based on the second spectrum.

[0090] Understandably, compared to the first spectrum directly derived through spectral analysis, the target spectrum is more useful for subsequent processing. For example, the target spectrum is more helpful in determining the perception result corresponding to the perception performed on the first signal at the first moment. In some cases, the target spectrum has a higher sparsity than the first spectrum, which facilitates compressed reporting of perception data, thereby reducing the amount of reported data.

[0091] In the embodiment of the present application, the first device may be a receiving device of the first signal, or a device that processes the received first signal to obtain data (i.e., the target spectrum, target measurement quantity, or target data included in the first information). The first device may be a base station or a user equipment (UE, also known as a terminal).

[0092] The second device may be a device that transmits the first signal, or a device that performs subsequent processing on data sent by the first device (i.e., the target spectrum, target measurement value, or target data included in the first information). The second device may be a sensing function (SF) network element (see Explanation 1 below for details), also known as a sensing network element or a sensing network function. The second device may be located on the RAN side or the core network side.

[0093] In steps 301 and 302, the first device may acquire a target spectrum and report the target spectrum to the second device; alternatively, the first device may acquire the target spectrum and, based on the target spectrum, obtain a target measurement quantity and report at least one of the target spectrum and the target measurement quantity to the second device; alternatively, the first device may acquire the target spectrum and, based on the target spectrum, obtain a target measurement quantity and target data, and report at least one of the target spectrum, the target measurement quantity, and the target data to the second device. The target measurement quantity may include, for example, parameters such as delay, Doppler, or angle.

[0094] If the first device acquires the target spectrum and reports it to the second device, the amount of reported data can be reduced, thereby reducing communication resources, compared to the first device directly reporting the first spectrum to the second device. Furthermore, the second device performs subsequent processing based on the target spectrum, which is more conducive to obtaining perception results than the second device performs subsequent processing based on the first spectrum.

[0095] If the first device acquires the target measurement quantity based on the target spectrum, compared to if the first device acquires the target measurement quantity based on the first spectrum, it is more conducive to obtaining a sensing result, can improve sensing performance, and reduce the probability of false detection. In addition, compared to reporting the target spectrum, the signaling interaction overhead for reporting the target measurement quantity can be significantly reduced.

[0096] If the first device compresses the target spectrum to obtain target data and reports the target data to the second device, the amount of reported data can be reduced compared to directly reporting the first spectrum to the second device, thereby reducing communication resources. Furthermore, the second device performs subsequent processing based on the target data, which is more conducive to obtaining perception results than subsequent processing based on the first spectrum.

[0097] As can be seen, in this embodiment of the present application, compared to the first spectrum directly obtained through spectrum analysis, the target spectrum can reduce clutter interference to a certain extent. Therefore, the target spectrum is more conducive to subsequent processing. On the one hand, it facilitates subsequent processing by the receiving device to obtain the perception results; on the other hand, it reduces the amount of reported data, thereby reducing signaling overhead and conserving communication resources.

[0098] Optionally, the first information further includes at least one of the following:

[0099] the ID of the first signal;

[0100] the ID of the second spectrum;

[0101] The timestamp of the first moment is used to indicate the time of the first moment.

[0102] By sending the above data to the second device, the second device can better perform subsequent processing based on the above data, which is more conducive to obtaining perception results.

[0103] In some embodiments, the first device obtains first information including at least one of the following:

[0104] The first device acquires the first spectrum and the second spectrum, and obtains the target spectrum based on the first spectrum and the second spectrum;

[0105] The first device determines the target measurement quantity according to the target spectrum;

[0106] The first device performs data compression processing on the target spectrum to obtain the target data.

[0107] In this embodiment, the first device can receive the first signal at a first moment and process the received first signal to obtain a first spectrum. In this case, the first device serves as a receiving end device of the first signal and a device that processes the received first signal.

[0108] The first device may receive the second signal at the second time and process the received second signal to obtain the second spectrum. Alternatively, the second device may obtain the second spectrum from another device. Various optional implementations of the first device obtaining the second spectrum will be described in detail below.

[0109] There are many ways for the first device to obtain a target spectrum based on the first and second spectra, or in other words, there can be multiple types of target spectra. The first device can perform a single process based on the first and second spectra to obtain the target spectrum, or it can perform multiple processes to obtain the target spectrum, and various processing methods can be used. Various optional implementations of the first device obtaining the target spectrum will be described in detail below.

[0110] The first device may determine the target measurement quantity based on the target spectrum by performing signal detection based on the target spectrum, detecting the perceived target, and obtaining the target measurement quantity. Among the target measurement quantities, the target measurement quantity corresponding to any detected perceived target may include at least one of the following: delay, Doppler, azimuth, and elevation. Specifically, the format of the target measurement quantity is as shown in Table 2.

[0111] Table 2

[0112] As mentioned above, the presence of clutter in the first spectrum results in insufficient sparsity in the corresponding dimension, resulting in lower data compression performance. In some cases, the target spectrum may be even more sparse than the first spectrum, allowing for a higher compression ratio during data compression, thus improving data compression performance.

[0113] Based on this, when the target spectrum has a high sparsity, the first device can perform data compression on the target spectrum and send the compressed target data to the second device, thereby further reducing the amount of reported data.

[0114] The specific method for the first device to perform data compression processing on the target spectrum can adopt relevant technologies, which will not be specifically described in the embodiments of the present application.

[0115] In some embodiments, the first device acquires the first spectrum and the second spectrum, including at least one of the following:

[0116] The first device acquires the first spectrum during execution of a first sensing service, and acquires the second spectrum pre-stored by the first device, where the second spectrum is stored in the first device before the first sensing service is executed;

[0117] The first device obtains the first spectrum during execution of a first sensing service, and obtains the second spectrum from the second device, where the second spectrum is reported by the first device to the second device before the first sensing service is executed;

[0118] The first device obtains the first spectrum and the second spectrum while performing the second sensing service.

[0119] Wherein, the first sensing service includes a first sensing event;

[0120] The second sensing service includes a first sensing event and a second sensing event;

[0121] The first perception event is an event perceived by the first signal at the first moment;

[0122] The second perception event is an event that is perceived through the second signal at the second moment.

[0123] In this embodiment, the source of the second spectrum can be divided into the following three cases:

[0124] Case 1: The second spectrum is acquired and stored by the first device in advance. For example, the first device acquires the second spectrum by transmitting, receiving, and measuring the second signal at the second moment in advance, and the first device stores the second spectrum. In this way, after acquiring the first spectrum at the first moment, the first device can simply retrieve the stored second spectrum.

[0125] Case 2: The second spectrum is recorded in advance by the first device and reported by the first device to the second device. For example, the first device obtains the second spectrum in advance by transmitting, receiving and measuring the second signal at the second moment, and the first device reports the second spectrum to the second device. After the second device receives the second spectrum, the second device can store the second spectrum, or the second spectrum can be stored by a preset network node accessible to the second device. When the first device performs the first perception service through the first signal, the second device can send the second spectrum to the first device, or the first device can request the second device to obtain the second spectrum.

[0126] In scenario 2, the first device can obtain the second spectrum from the second device before executing the first sensing service; alternatively, the first device can obtain the second spectrum from the second device after executing the first sensing service; or alternatively, the first device can obtain the second spectrum from the second device while executing the first sensing service. In other words, the order in which the first device obtains the first and second spectra is not limited.

[0127] Case 3: The second spectrum is obtained during the execution of the second sensing service. For example, the first device first executes the second sensing event using the second signal at the second time to obtain the second spectrum. The second device then executes the first sensing event using the first signal at the first time to obtain the first spectrum.

[0128] In Case 1 and Case 2, since the second spectrum is recorded in advance by the first device, the second moment is before the first moment and is separated from the first moment by a long time.

[0129] In case 3, since both the second spectrum and the first spectrum are acquired in the process of performing the sensing service, the second moment is before the first moment and is relatively close to the first moment.

[0130] In case 2, there is an interaction between the first device and the second device regarding the second spectrum. In case 1 and case 3, there is no interaction regarding the second spectrum.

[0131] It should be noted that the configuration of the second signal may be the same as or different from the configuration of the first signal. In general, the signal configuration of the second signal is the same as the signal configuration of the first signal to ensure a one-to-one mapping between each unit of the second spectrum and the first spectrum in the corresponding dimension.

[0132] In some embodiments, the first device determines the target measurement quantity according to the target spectrum, including:

[0133] In a case where an amplitude value or a power value of at least one unit of the target spectrum is greater than or equal to a first preset threshold, the first device determines the target measurement quantity according to the target spectrum.

[0134] In this embodiment, if the amplitude or power value of at least one unit of the target spectrum is greater than or equal to a first preset threshold, it indicates that at least one unit of the target spectrum contains valid (or valuable) information. Therefore, if this condition is met, the target measurement quantity can be determined more effectively, while if this condition is not met, the target measurement quantity may not be effectively determined. In this way, when the amplitude or power value of at least one unit of the target spectrum is greater than or equal to the first preset threshold, determining the target measurement quantity based on the target spectrum can reduce unnecessary resource waste.

[0135] It should be noted that a “spectrum” is a matrix, and the “units” involved in the embodiments of the present application can be understood as elements in the matrix.

[0136] The target spectrum involved in the embodiments of the present application may include various types. The types that the target spectrum may include are specifically described below:

[0137] In some embodiments, the target profile includes at least one of the following types:

[0138] a third spectrum, the third spectrum being a spectrum obtained by performing a target operation on the first spectrum and the second spectrum, the target operation being a subtraction correlation operation;

[0139] a fourth spectrum, wherein the fourth spectrum is a spectrum obtained by performing a first processing on the third spectrum based on a second preset threshold;

[0140] a fifth spectrum, the fifth spectrum being a spectrum obtained by performing a second processing on the third spectrum based on the prior information;

[0141] a sixth spectrum, the sixth spectrum being a spectrum obtained by performing a second processing on the fourth spectrum based on the prior information;

[0142] a seventh spectrum, the seventh spectrum being a spectrum obtained by performing a first processing on the fifth spectrum based on a second preset threshold;

[0143] an eighth spectrum, the eighth spectrum being a portion of the third spectrum where the Doppler dimension is zero;

[0144] a ninth spectrum, the ninth spectrum being a portion of the fourth spectrum where the Doppler dimension is zero;

[0145] a tenth spectrum, wherein the eighth spectrum is a portion of the fifth spectrum where the Doppler dimension is zero;

[0146] an eleventh spectrum, the eleventh spectrum being a portion of the sixth spectrum where the Doppler dimension is zero;

[0147] a twelfth spectrum, the twelfth spectrum being a portion of the seventh spectrum where the Doppler dimension is zero;

[0148] a thirteenth spectrum, the thirteenth spectrum being a portion of the third spectrum where the Doppler dimension is not zero;

[0149] a fourteenth spectrum, the fourteenth spectrum being a portion of the fourth spectrum where the Doppler dimension is not zero;

[0150] a fifteenth spectrum, the fifteenth spectrum being a portion of the fifth spectrum where the Doppler dimension is not zero;

[0151] a sixteenth spectrum, the sixteenth spectrum being a portion of the sixth spectrum where the Doppler dimension is not zero;

[0152] The seventeenth spectrum is a portion of the seventh spectrum where the Doppler dimension is not zero.

[0153] The third spectrum is obtained by performing a target operation on the first spectrum and the second spectrum. The target operation is a correlation subtraction operation. Therefore, the target operation can be understood as a clutter cancellation operation.

[0154] Optionally, the target operation includes at least one of the following operations:

[0155] a first operation, wherein the first operation is a subtraction of the complex spectrum of the second spectrum from the complex spectrum of the first spectrum;

[0156] a second operation, wherein the second operation is the magnitude spectrum of the first spectrum minus the magnitude spectrum of the second spectrum;

[0157] a third operation, wherein the third operation is the power spectrum of the first spectrum minus the power spectrum of the second spectrum;

[0158] A fourth operation, wherein the third operation is a dot multiplication of the first result and the second result;

[0159] A fifth operation, wherein the fourth operation is dot multiplication of the first result by the third result;

[0160] The first result is a result obtained by subtracting the complex spectrum of the second spectrum from the complex spectrum of the first spectrum;

[0161] The second result is a sign function operation result of a fourth result, and the fourth result is a result obtained by subtracting the magnitude spectrum of the second spectrum from the magnitude spectrum of the first spectrum;

[0162] The third result is a sign function operation result of the fifth result, and the fifth result is a result obtained by subtracting the power spectrum of the second spectrum from the power spectrum of the first spectrum.

[0163] Exemplarily, the first spectrum is represented as a vector or matrix S, and the second spectrum is represented as a vector or matrix C.

[0164] When the first operation is adopted, the third spectrum is equal to the complex spectrum of the first spectrum minus the complex spectrum of the second spectrum. That is, the third spectrum is SC.

[0165] When the second operation is used, the third spectrum is equal to the magnitude spectrum of the first spectrum minus the magnitude spectrum of the second spectrum. That is, the third spectrum is |S|-|C|.

[0166] When the third operation is used, the third spectrum is equal to the power spectrum of the first spectrum minus the power spectrum of the second spectrum. That is, the third spectrum is |S| 2 -|C| 2 .

[0167] When the fourth operation is used, the third spectrum is equal to the product of the complex spectrum of the first spectrum minus the complex spectrum of the second spectrum, and the sign function of the magnitude spectrum of the first spectrum minus the magnitude spectrum of the second spectrum. In other words, the third spectrum is (SC).*sign(|S|-|C|).

[0168] When the fifth operation is used, the third spectrum is equal to the product of the complex spectrum of the first spectrum minus the complex spectrum of the second spectrum and the sign function operation result of the power spectrum of the first spectrum minus the power spectrum of the second spectrum. That is, the third spectrum is (SC).*sign(|S| 2 -|C| 2 ).

[0169] Among them, |*| represents the modulus operation of a vector or matrix, .* represents the dot product operation of a vector or matrix, and the dot product operation is the multiplication of the corresponding elements of the matrix. sign(x) represents the sign function operation. The sign function operation is defined as follows:

[0170] Optionally, performing the first processing on the correlation spectrum based on the second preset threshold includes:

[0171] retaining the third unit of the correlation spectrum and setting the fourth unit of the correlation spectrum to zero;

[0172] Wherein, the third unit is a unit whose amplitude value or power value is greater than or equal to the second preset threshold;

[0173] The fourth unit is a unit whose amplitude value or power value is smaller than the second preset threshold.

[0174] Here, the first processing of the correlation spectrum based on the second preset threshold can be understood as performing a threshold decision on the amplitude or power of the correlation spectrum. Here, the correlation spectrum can include the third spectrum or the fifth spectrum.

[0175] The fourth spectrum is obtained by applying an amplitude or power threshold to the third spectrum. For example, cells in the third spectrum with amplitude or power values ​​greater than or equal to the second preset threshold are retained, and the complex values, power values, or amplitude values ​​of cells with amplitude or power values ​​less than the second preset threshold are set to 0, thereby obtaining the fourth spectrum.

[0176] Specifically, in the case where the third spectrum is a complex spectrum, the complex value on each unit is modulo the amplitude value, or the square of the modulo value is calculated to obtain the power value, and then the above-mentioned threshold judgment is performed on the amplitude value or power value corresponding to each unit: if the amplitude value or power value is greater than or equal to the second preset threshold, the complex value of the unit is retained; if the amplitude value or power value is less than the second preset threshold, the complex value of the unit is set to 0.

[0177] In the case where the third spectrum is an amplitude spectrum or a power spectrum, the above-mentioned threshold judgment is directly performed on the amplitude value or power value of each unit: if the amplitude value or power value is greater than or equal to the second preset threshold value, the amplitude value or power value of the unit is retained; if the amplitude value or power value is less than the second preset threshold value, the amplitude value or power value of the unit is set to 0.

[0178] It should be noted that, in addition to performing amplitude or power threshold determination on the third spectrum, corresponding amplitude or power threshold determination can also be performed on the first spectrum.

[0179] In the embodiment of the present application, the fourth spectrum has a higher sparsity than the first spectrum, which helps to improve data compression performance.

[0180] Optionally, performing the second processing on the correlation spectrum based on the prior information includes:

[0181] retaining the fifth unit of the correlation spectrum and setting the sixth unit of the correlation spectrum to zero;

[0182] The sixth unit is a unit determined to be unrelated to the perception target based on the prior information;

[0183] The fifth unit is a unit that does not belong to the sixth unit among the units of the correlation spectrum.

[0184] Here, the relevant spectrum may include the third spectrum or the fourth spectrum.

[0185] The fifth spectrum is obtained by performing a second processing on the third spectrum based on the prior information. For example, if the prior information indicates that a specific unit or units in the third spectrum are not associated with the perception target, the complex value, amplitude value, or power value of the unit or units is set to 0.

[0186] In a typical example, the third spectrum is a complex spectrum in the range-azimuth dimension. That is, in the third spectrum, a cell defined by a distance value and an azimuth value corresponds to that complex value. Based on prior information, if the location defined by a specific distance and azimuth is a wall, indicating that the complex value in that cell corresponds to a signal reflected from the wall, the complex value in that cell is set to 0 to prevent the wall-reflected signal from affecting target detection.

[0187] It should be noted that, in addition to performing the second processing on the third spectrum, the corresponding second processing can also be performed on the first spectrum. To avoid repetition, this will not be described in detail.

[0188] In the embodiment of the present application, the fifth spectrum has a higher sparsity than the first spectrum, which helps to improve data compression performance.

[0189] Accordingly, the sixth spectrum is obtained by performing a second processing on the fourth spectrum based on the prior information.

[0190] It can be understood that the sixth spectrum is obtained by first performing the first processing on the third spectrum and then performing the second processing. Compared with the first spectrum, the sixth spectrum has a higher sparsity, which helps to improve data compression performance.

[0191] Accordingly, the seventh spectrum is obtained by first performing the second processing on the third spectrum and then performing the first processing. Compared with the first spectrum, the seventh spectrum has a higher sparsity, which helps to improve data compression performance.

[0192] The eighth spectrum, the ninth spectrum, the tenth spectrum, the eleventh spectrum, and the twelfth spectrum are portions where the Doppler of the corresponding spectrum in the third spectrum, the fourth spectrum, the fifth spectrum, the sixth spectrum, and the seventh spectrum is zero, respectively.

[0193] Taking the third spectrum corresponding to the eighth spectrum as an example, the third spectrum has M units in the delay dimension, N units in the Doppler dimension, P units in the azimuth dimension, and Q units in the elevation dimension; among them, any one, any two, or any three of M, N, P, and Q can be 1.

[0194] Then the eighth spectrum is: a spectrum with only one unit of Doppler 0 in the Doppler dimension of the third spectrum, M units in the delay dimension, P units in the azimuth dimension, and Q units in the elevation dimension.

[0195] In a typical example, the third spectrum is a spectrum in the delay-Doppler dimension, and its matrix size is M×N. Then the eighth spectrum is a spectrum with only one unit with Doppler 0 in the Doppler dimension and M units in the delay dimension, that is, its matrix size is M×1.

[0196] In another typical example, the third spectrum is a spectrum in the delay-Doppler-azimuth dimension, and its matrix size is M×N×P. Then the eighth spectrum is a spectrum with only one unit with Doppler 0 in the Doppler dimension, M units in the delay dimension, and P units in the azimuth dimension, that is, its matrix size is M×1×P.

[0197] The thirteenth, fourteenth, fifteenth, sixteenth, and seventeenth spectra are the non-zero Doppler portions of the corresponding spectra in the third, fourth, fifth, sixth, and seventh spectra, respectively. The thirteenth spectrum can be considered the remainder of the third spectrum, excluding the eighth spectrum. The other spectra can be understood similarly.

[0198] Taking the third spectrum corresponding to the thirteenth spectrum as an example, the thirteenth spectrum is a spectrum with N-1 units with non-zero Doppler in the Doppler dimension of the third spectrum, M units in the delay dimension, P units in the azimuth dimension, and Q units in the elevation dimension.

[0199] In a typical example, the third spectrum is a spectrum in the delay-Doppler dimension, and its matrix size is M×N. Then the thirteenth spectrum is a spectrum with N-1 units with non-zero Doppler in the Doppler dimension and M units in the delay dimension, that is, its matrix size is M×N-1.

[0200] In another typical example, the third spectrum is a spectrum in the delay-Doppler-azimuth dimension, and its matrix size is M×N×P. Then the thirteenth spectrum is a spectrum with only N-1 units with non-zero Doppler in the Doppler dimension, M units in the delay dimension, and P units in the azimuth dimension, that is, its matrix size is M×N-1×P.

[0201] Compared with the first spectrum, the eighth to seventeenth spectra have higher sparsity, which helps to improve data compression performance.

[0202] The prior information involved in the embodiments of the present application can be determined based on the second spectrum, or determined by point cloud information obtained through radar imaging or lidar scanning, or determined by information related to objects in the environment obtained through other methods.

[0203] Determining the prior information based on the second spectrum may involve, for example, performing threshold detection or maximum detection on the second spectrum to obtain information related to objects present in the environment at the second moment. Specifically, for each detected object, at least one of the following information is included: time delay, Doppler, azimuth, elevation, signal strength, and signal power in the relevant dimension.

[0204] Prior information is determined from point cloud information acquired through radar imaging or lidar scanning. For example, threshold detection or maximum detection can be performed on the point cloud information to obtain information related to objects in the environment. Specifically, for each detected object, at least one of the following information is included: time delay, Doppler, azimuth, elevation, signal strength, and signal power in the relevant dimension.

[0205] Prior information is determined by information about objects in the environment obtained through other means, such as image recognition through a camera or information obtained through manual calibration; it may include information such as the location of objects in the environment, object type (vehicle, building, etc.) or radar cross section (RCS).

[0206] In some embodiments, the method further comprises:

[0207] The first device obtains the prior information.

[0208] The first device obtains the prior information, including at least one of the following:

[0209] The first device determines the prior information based on the second spectrum;

[0210] The first device receives the prior information from the second device;

[0211] The first device obtains the prior information by accessing the third device.

[0212] Specifically, in a case where the target spectrum includes at least one of the fifth to seventh spectra, the tenth to twelfth spectra, and the fifteenth to seventeenth spectra, the first device also needs to acquire prior information.

[0213] If the prior information is determined based on the second spectrum, the first device determines the prior information based on the second spectrum using the same method for obtaining the second spectrum. If the prior information is determined using other methods, the first device can request the prior information from the second device, which can then send it directly to the first device. Alternatively, the second device can access a predefined network node that stores the prior information to obtain the prior information and then send it to the first device. The first device can also access a third device to obtain the prior information, which can be understood as the predefined network node that stores the prior information.

[0214] In some embodiments, when the second processing is performed on the correlation spectrum based on the prior information, the method further includes:

[0215] The first device obtains third information, where the third information includes at least one of the following information:

[0216] location information of the first device;

[0222] Obtain location information through WiFi / 4G / 5G positioning (and future 5.5G / 6G positioning);

[0223] Obtain position information through the inertial measurement unit (IMU) equipped with the device;

[0224] For devices at fixed locations (eg, base stations, road side units (RSUs)), their locations are determined during deployment, and the location information is stored in the devices or designated network nodes.

[0225] The attitude information, namely the orientation of the antenna panel of the first device, may be an attitude in a global coordinate system or a local coordinate system, including an azimuth angle, a pitch angle, and a roll angle.

[0226] Optionally, the method for obtaining the posture information includes at least one of the following:

[0228] For devices at fixed locations (e.g., base stations, RSUs), their posture is determined during deployment, and the posture information is stored in the device or in a designated network node.

[0229] The velocity information may be the velocity in the global coordinate system, or the velocity relative to a certain reference coordinate system, and the velocity includes the magnitude and direction of the velocity.

[0230] Optionally, the speed information is obtained by at least one of the following methods:

[0231] Obtain speed information by differentiating the position information;

[0232] Obtain speed information through the IMU equipped with the device;

[0233] For a device at a fixed location (eg, base station, RSU), its velocity is 0.

[0234] In some embodiments, the method further comprises:

[0235] The first device obtains second information, where the second information is used to configure information related to the first information.

[0236] It is understandable that before acquiring the first information, the first device may first acquire the second information to configure the first device to determine the first information.

[0237] Optionally, the second information includes at least one of the following information:

[0238] Information for indicating the type of the target spectrum, that is, information indicating the type of the target spectrum, for indicating which one or more of the third to seventeenth spectra the target spectrum includes;

[0239] Information used to indicate the target measurement quantity, that is, target measurement quantity indication information, used to indicate which one or more measurement quantities the target measurement quantity includes;

[0240] Information for indicating a target dimension of a related spectrum, i.e., dimension indication information, is used to indicate dimension information corresponding to the related spectrum. The related spectrum here may include at least one of the second spectrum and the target spectrum, and the target spectrum may be at least one of the third spectrum to the seventeenth spectrum;

[0241] Information for indicating a target operation, the target operation being a subtraction correlation operation for the first spectrum and the second spectrum, that is, for indicating which of the first to fifth operations the target operation is;

[0242] Information used to indicate a first preset threshold, where the first preset threshold is a threshold used to determine the target measurement amount, that is, when the first device needs to obtain the target measurement amount, it is used to determine the target measurement amount;

[0243] Information for indicating a second preset threshold, where the second preset threshold is a threshold for processing a related spectrum, where the related spectrum includes the third spectrum or the fifth spectrum, and when the target spectrum includes the fourth spectrum or the seventh spectrum, and a spectrum determined based on the fourth spectrum or the seventh spectrum, the second preset threshold is used to determine the fourth spectrum or the seventh spectrum;

[0244] Information for instructing to perform data compression processing on the target spectrum, that is, when the second information includes this information, the first device needs to perform data compression processing on the target spectrum to obtain target data;

[0245] The information is used to indicate the relevant parameters of the data compression process, that is, when data compression processing is required for the target spectrum, it is used to indicate the data compression method or other relevant parameters.

[0246] Optionally, the manner in which the first device obtains the first information includes:

[0247] The first device receives at least part of the first information from the second device;

[0248] The first device determines at least part of the first information based on a protocol agreement.

[0249] In other words, some of the first information may be sent by the second device when performing the sensing service, while other information is a fixed configuration agreed upon by the protocol. For example, the target dimension indication can be determined based on the sensing requirement information and the sensing signal configuration information. In this case, the target dimension indication is more likely to be sent by the second device. The target operation indication may be a fixed operation method agreed upon by the protocol, such as an operation method with good performance confirmed through simulation.

[0250] Optionally, the information used to indicate the first preset threshold includes any one of the following:

[0251] a first threshold value, wherein the value of the first preset threshold is the first threshold value;

[0252] A first calculation window and a first operation method, wherein the first calculation window is used to indicate a first unit of the target spectrum, and the value of the first preset threshold is a first value obtained by using the first operation method for the first unit;

[0253] The first calculation window, the first operation method and the first preset coefficient, wherein the value of the first preset threshold is a second value obtained by multiplying the first value by the first preset coefficient.

[0254] The first threshold value may be understood as a fixed threshold value.

[0255] The second and third items above can be understood as adaptive threshold values. For example, one or more cells within the first calculation window may be calculated using the first calculation method to obtain the adaptive threshold value. Alternatively, the result obtained by calculating the first calculation method using the one or more cells within the first calculation window is multiplied by (or added to) a preset coefficient to obtain the final adaptive threshold value.

[0258] Optionally, the information used to indicate the second preset threshold includes any one of the following:

[0259] a second threshold value, wherein the value of the second preset threshold is the second threshold value;

[0260] a second calculation window and a second operation method, wherein the second calculation window is used to indicate a second unit of the correlation spectrum, and the value of the second preset threshold is a third value obtained by the second unit using the second operation method;

[0261] The second calculation window, the second operation method and the second preset coefficient, and the value of the second preset threshold are a fourth value obtained by multiplying the third value by the second preset coefficient.

[0262] The second threshold value can be understood as a fixed threshold value.

[0263] The second and third items mentioned above can be understood as adaptive threshold values. For details, please refer to the above description of the first preset threshold. To avoid repetition, this will not be described in detail.

[0264] Optionally, the target dimension includes at least one of the following:

[0265] Any dimension among the time delay dimension, Doppler dimension, azimuth dimension and elevation angle dimension;

[0266] The joint dimension of any two of the delay dimension, Doppler dimension, azimuth dimension, and elevation dimension;

[0267] The joint dimension of any three of the delay dimension, Doppler dimension, azimuth dimension, and elevation dimension;

[0268] The combined dimension of time delay dimension, Doppler dimension, azimuth dimension and elevation angle dimension.

[0269] (1) Any dimension among the time delay dimension, Doppler dimension, azimuth dimension and elevation dimension

[0270] In a typical embodiment, for example, in a ranging use case, the focus is on the target spectrum in the delay dimension. In this case, the target spectrum can be understood as the delay spectrum.

[0271] In a typical embodiment, for example, in a use case of respiration detection or heartbeat monitoring, the focus is on a target spectrum in the Doppler dimension. In this case, the target spectrum can be understood as a Doppler spectrum.

[0272] In a typical embodiment, for example, in a use case of (communication) beam selection, the target spectrum in the azimuth dimension is of primary interest. In this case, the target spectrum can be understood as the azimuth spectrum.

[0273] (2) The joint dimension of any two dimensions among the time delay dimension, Doppler dimension, azimuth dimension, and elevation dimension

[0274] In a typical embodiment, for example, in a use case of moving target detection, the focus is on the target spectrum in the delay-Doppler dimension. In this case, the target spectrum can be understood as the delay-Doppler spectrum.

[0275] In a typical embodiment, for example, in the use case of obstacle detection, the focus is on the target spectrum in the delay-azimuth dimension. In this case, the target spectrum can be understood as the delay-azimuth spectrum.

[0276] (3) The joint dimension of any three of the following dimensions: time delay, Doppler, azimuth, and elevation

[0277] In a typical embodiment, for example, in a use case of target positioning or tracking, after detecting a moving perceived target based on the above-mentioned delay-Doppler spectrum, the angle of the perceived target is further estimated in the azimuth dimension. At this time, the main focus is on the target spectrum in the delay-Doppler-azimuth dimension. At this time, the target spectrum can be understood as the delay-Doppler-azimuth spectrum.

[0278] In a typical embodiment, for example, in radar imaging or environment reconstruction use cases, the focus is on the target spectrum in the delay-azimuth-elevation dimension. In this case, the target spectrum can be understood as the delay-azimuth-elevation spectrum.

[0279] (4) The joint dimension of the four dimensions of time delay, Doppler, azimuth and elevation, i.e., time delay-Doppler-azimuth-elevation dimension.

[0280] In a typical embodiment, for example, the scenario of motion target detection in three-dimensional space, specifically the use case of detection, positioning and tracking of drones, mainly focuses on the target spectrum in the delay-Doppler-azimuth-pitch angle dimension. In this case, the target spectrum can be understood as the delay-Doppler-azimuth-pitch angle spectrum.

[0281] It should be noted that in some scenarios, such as single-base sensing scenarios, the delay corresponding to the sensed target differs from the distance of the sensed target by only a constant coefficient, and the Doppler corresponding to the sensed target differs from the speed of the sensed target by only a constant coefficient. Therefore, the delay dimension can be considered equivalent to the distance dimension, and the Doppler dimension can be considered equivalent to the speed dimension. In the embodiments of this application, for simplicity of description, the delay dimension refers to the delay dimension or the distance dimension, and the Doppler dimension refers to the Doppler dimension or the speed dimension.

[0282] The above is the first device side embodiment of the present application. The second device side embodiment of the present application is described below.

[0283] FIG4 shows a flow chart of an information transmission method provided by an embodiment of the present application. As shown in FIG4 , the information transmission method includes the following steps:

[0284] Step 401: The second device performs a target operation, where the target operation includes at least one of the following:

[0285] receiving first information from a first device, wherein the first information includes at least one of a target spectrum, a target measurement quantity, and target data;
