[0052] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0053] 1. Integrated Sensing And Communication (ISAC)

[0054] Communication and perception integration can also be called interawareness integration. In the future, Beyond Fifth Generation (B5G) and 6G wireless communication systems are expected to provide various high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for self-driving cars. Sensing and communication systems are usually designed separately and occupy different frequency bands. ISAC enables sensing and communication systems to share the same frequency band and hardware, improve frequency efficiency, and reduce hardware costs. ISAC will become a key technology for future wireless communication systems to support many important application scenarios. Typical applications of ISAC include: navigation and obstacle avoidance for autonomous vehicles, indoor positioning and activity recognition based on Wi-Fi, communication and sensing for unmanned aircraft, extended reality (XR), radar and communication integration, etc. Each application has different requirements, restrictions, and regulatory issues.

[0055] ISAC achieves low-cost integration of communication and perception functions by sharing hardware equipment and defining functions with software. Its main features are: unified and simplified architecture, reconfigurable and scalable functions, and improved efficiency and reduced costs. The advantages of integrated communication and perception are mainly in three aspects: reduced equipment cost and size, improved spectrum utilization, and improved system performance.

[0056] 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 below.

[0057] Table 1:

[0058]

[0059] 2. Resource overhead in the integration of communication and synaesthesia.

[0060] In communication systems, especially in Multiple-Input Multiple-Output (MIMO) scenarios, each port needs to be configured with a corresponding reference signal; as the number of ports increases, the time-frequency resource overhead of the reference signal also increases. Figure 2As shown in the figure, it is an example of a 32-port Channel State Information Reference Signal (CSI-RS) configuration. The time-frequency resource overhead of CSI-RS is already large. With the evolution of communication systems, in massive MIMO (mMIMO) and extremely large-scale MIMO (el-MIMO) scenarios, the time-frequency resource overhead required for CSI-RS will be further increased, resulting in a decrease in the gain of the MIMO system. Therefore, how to reduce the time-frequency resource overhead of the reference signal as much as possible while satisfying channel measurement is a very important issue.

[0061] In addition, in the integrated perception service, in order to achieve high-performance perception of distance, speed, and angle, the resource overhead of the perception signal is relatively large. First, the resolution of distance perception depends on the bandwidth of the perception signal, so the perception signal bandwidth usually needs to be in the order of hundreds of MHz or above; second, the resolution of speed perception depends on the duration of the perception signal, so the duration of the perception signal usually needs to be in the order of ten ms or above; finally, the resolution of angle perception depends on the antenna aperture, and in order to achieve high-resolution angle measurement, a larger antenna aperture needs to be configured.

[0062] If the perception signal is evenly distributed in the required bandwidth, duration and antenna aperture according to the traditional method, the resource overhead of the perception signal in time, frequency and space domains will be relatively large. Therefore, how to reduce the resource overhead of the perception signal in time, frequency and space domains as much as possible while meeting the perception requirements is also an important issue in synaesthesia integration.

[0063] 3. Compressed sensing.

[0064] Compressed sensing is also known as compressed sampling or sparse sampling. As a new sampling theory, it exploits the sparse characteristics of the signal, obtains discrete samples of the signal by random sampling under the condition of less than the Nyquist sampling rate, and then reconstructs the signal through a nonlinear reconstruction algorithm. Therefore, compressed sampling can reduce the sampling rate of data, thereby reducing the amount of data and the requirements for high-speed sampling.

[0065] Suppose \(x\) represents a one-dimensional signal of length \(N\), which is the original signal. Its signal \(s\) in the transform domain is a \(K\)-sparse signal, that is, the number of sample points with significant values in \(s\) is no more than \(K\); \(\Psi\) is a sparse matrix that transforms the signal \(s\) into \(x\); \(\Phi\) is an observation matrix, corresponding to the subsampling process, which projects the high-dimensional signal \(x\) into a low-dimensional space to obtain the subsampled signal \(y = \Phi\Psi s\). Usually, \(\Psi\) and \(\Phi\) are combined into a matrix, denoted as \(\Theta=\Phi\Psi\), which is called the sensing matrix.

[0066] The length of the subsampled signal \(y\) is \(M\), and \(M < N\). Under traditional Nyquist sampling, the output signal is \(x\); while under compressive sampling, the output signal is \(y\); due to \(M < N\), the sampling rate is reduced.

[0067] Combining compressive sensing with integrated communication and sensing, at least one of the following situations occurs for \(x\), \(y\), and \(s\):

[0068] \(x\) and \(y\) are frequency-dimensional signals, and \(s\) is a time-delay-dimensional signal;

[0069] \(x\) and \(y\) are slow-time-dimensional signals, and \(s\) is a Doppler-dimensional signal;

[0070] \(x\) and \(y\) are signals of each antenna element or antenna port in the horizontal direction of the antenna array, and \(s\) is an azimuth-angle-dimensional signal;

[0071] \(x\) and \(y\) are signals of each antenna element or antenna port in the vertical direction of the antenna array, and \(s\) is an elevation-angle-dimensional signal.

[0072] In order to reconstruct the signal \(x\) or \(s\) before compression from the compressed signal \(y\), there are the following two conditions:

[0073] Sparsity: \(x\) or the transform-domain signal \(s\) of \(x\) has sparsity, that is, the number of sample points with significant values is no more than \(K\);

[0074] Incoherence: The bases (columns of the matrix) of the observation matrix \(\Phi\) and the bases (columns of the matrix) of the sparse matrix \(\Psi\) are uncorrelated.

[0075] In a communication channel or a sensing channel of integrated communication and sensing, the sparsity condition is usually satisfied. Typical observation matrices and sparse matrices that satisfy incoherence are:

[0076] Observation matrix: random Gaussian matrix, random Bernoulli matrix, partial orthogonal matrix, random sparse matrix, Toeplitz and circulant matrix, rotation matrix, Hadamard matrix;

[0077] Sparse matrix: discrete Fourier transform matrix, discrete pre-transform matrix, wavelet transform matrix, etc.

[0078] Next, in combination with the accompanying drawings, through some embodiments and their application scenarios, the signal configuration adaptive processing method provided by the embodiments of the present application will be described in detail.

[0079] Reference Figure 3 , the embodiment of the present application provides a signal configuration adaptive processing method, such as Figure 3 As shown, the signal configuration adaptive processing method includes:

[0080] Step 301, a first device obtains a target indicator of a target signal;

[0081] Step 302: The first device sends first information to the second device, where the first information is used to indicate at least one of a target resource pattern and whether to update the resource pattern of the target signal, and the target resource pattern is the updated resource pattern of the target signal;

[0082] Among them, the first information is determined based on the target indicator, the target indicator includes a first indicator, the first indicator is used to indicate the sparse characteristics of the power distribution of the target signal in the first domain, the first domain includes at least one of the delay domain, the Doppler domain and the angle domain; the resource pattern is used to represent the signal resources actually occupied by the target signal in the resource grid; the resource grid includes a group of signal resources in the second domain, and the second domain includes at least one of the time domain, the frequency domain and the space domain.

[0083] In the embodiment of the present application, the target signal may be any of the following:

[0084] The communication signal may be a communication signal in 5G NR and its evolved versions, or a communication signal of Wi-Fi, such as a reference signal, a data signal, and a synchronization signal; wherein the reference signal may be a CSI-RS, a dedicated demodulation reference signal (DM-RS), a phase tracking reference signal (PTRS), a sounding reference signal (SRS), or a positioning reference signal (PRS). The synchronization signal may include a secondary synchronization signal (SSS) or a primary synchronization signal (PSS).

[0085] A perception signal may be a signal newly designed for a perception function in 5G NR and its evolved versions or Wi-Fi, for example, a perception reference signal;

[0086] Communication-awareness integrated signal: A communication-awareness integrated signal refers to a signal that can be used for both communication and perception. It can be a newly designed communication-awareness integrated signal in 5G NR and its evolved versions or Wi-Fi, or an upgraded version based on an existing signal.

[0087] It should be understood that the above-mentioned first domain and second domain are associated, wherein the angle domain and the space domain are a pair of transform domains, and the signal in the space domain can be transformed into a signal in the angle domain through FFT. The signal configuration is in the space domain (corresponding to the antenna unit or antenna port), and the sparse characteristics of the target signal are in the angle domain; similarly, the delay domain and the frequency domain are a pair of transform domains, and the frequency domain signal can be transformed into the delay domain signal through IFFT, and the signal configuration is in the frequency domain, and the sparse characteristics of the target signal are in the delay domain; similarly, the Doppler domain and the slow time domain (or, the slow time domain can also be simply referred to as the time domain) are a pair of transform domains, and the slow time domain signal can be transformed into the Doppler domain through FFT, and the signal configuration is in the slow time domain, and the sparse characteristics of the target signal are in the Doppler domain.

[0088] It should be noted that the target signal sending device is not necessarily the second device. For example, in the application of the communication system, the target signal sending device is generally the second device, while in the application of synaesthesia integration, the target signal sending device may be the second device or may not be the second device.

[0089] Optionally, the specific device types of the first device and the second device may be set according to actual needs. For example, in some embodiments, the first device and the second device may include any of the following:

[0090] Case 1: the first device is a terminal, and the second device is an access network device or a core network device (such as a perception function network element);

[0091] Case 2: the first device is terminal 1, and the second device is terminal 2;

[0092] Case 3: the first device is an access network device, and the second device is a core network device;

[0093] Case 4: the first device is access network device 1, and the second device is access network device 2.

[0094] Optionally, some of the above situations (such as situation 1) are applicable to communication scenarios, and all of the situations are applicable to synaesthesia scenarios.

[0095] It should be understood that the resource pattern of the above-mentioned target signal can be understood as the configuration of time, frequency, and spatial resources, or as a partial configuration of time, frequency, and spatial resources. Since the first information is sent to the second device based on the target indicator of the target signal, the resource pattern of the target signal can be updated through the first information, which can make full use of the sparsity of the channel and reduce resource overhead as much as possible. At the same time, it can avoid the distortion of the measurement and the inability to completely reconstruct the full sampling signal, thereby improving the accuracy of the channel measurement or the perception performance.

[0146] It should be noted that, when the above-mentioned target indicator only includes the first indicator, the above-mentioned target information value can be directly the first indicator.

[0156] Taking the NR-based configuration as an example, the spatial domain resource grid can be determined by parameters [Mg, Ng, M, N, P].

[0157] The embodiment of the present application adaptively determines the target resource pattern through the target information value, and the target resource pattern selects part of the resources from the resource grid to be ultimately used for the resource configuration of the target signal, while the unselected part of the resources in the resource grid is the saved resource overhead. In this way, the resource overhead of at least one of the time domain, frequency domain and space domain can be significantly saved on the premise of being able to meet the performance of at least one of channel estimation and beamforming, or meeting the performance of at least one of delay, Doppler and angle measurement.

If the element in the sequence is '1', it means that the signal resources in the corresponding resource grid are allocated to the target signal, and if the element in the sequence is '0', it means that the signal resources in the corresponding grid are not allocated to the target signal.

[0182] Optionally, the second configuration information includes: at least one of the second mapping table and the related configuration of the second mapping function;

[0183] Among them, the relevant configuration of the second mapping function is used to generate a first pattern sequence; the second mapping table includes multiple candidate information values ​​and multiple second pattern sequences, and the candidate information values ​​and the second pattern sequences are mapped one by one, the candidate information value is used to indicate the candidate resource pattern after the resource pattern of the target signal in the second domain is updated, and the target information value is included in the multiple candidate information values; at least part of the first pattern sequence and the second pattern sequence are used to determine the candidate resource pattern.

The parameters that need to be pre-configured at this time may include the candidate second mapping function and the candidate parameters other than the target information value and the resource grid (e.g., the length of the resource grid) required for the candidate second mapping function to generate the first pattern sequence.

[0194] For example, the candidate second mapping function is a random Bernoulli function. In this case, the generated first pattern sequence can be directly used as a sequence of candidate resource patterns. Depending on the meaning of the target information value, the following situations may occur:

[0195] Case 1: The target information value can be the random number seed of the random Bernoulli function. In this case, the parameters required when the target information value and the resource grid are given are: the probability of "1" appearing in the random Bernoulli trial;

[0196] Case 2: The target information value is the probability of '1' appearing in a random Bernoulli trial, or the target information value is the number of '1's in the first pattern sequence, and the probability of '1' appearing in a random Bernoulli trial can be determined by the target information value. At this time, when the target information value and the resource grid are given, the parameter required is the random number seed of the random Bernoulli function.

[0197] For example, the candidate second mapping function is a random Gaussian function, and the generated random number is compared with the second preset threshold: the mapping greater than the second preset threshold is '1' in the first pattern sequence, and the mapping less than the second preset threshold is '0' in the first pattern sequence; at this time, the target information value can be the mean, variance (or standard deviation) of the random Gaussian function and one of the second preset threshold, and the required parameters are the other two.

[0198] Optionally, for example, the length of the resource grid is the number of at least one of subcarriers, OFDM symbols and antenna ports (or antenna units) in the resource grid configured by the first configuration information.

[0199] Optionally, when the second mapping table is configured, the second pattern sequence associated with the target information value can be obtained by looking up the second mapping table to determine the target pattern sequence. In this case, the candidate information value can be the ID of the second pattern sequence, that is, the target information value is the ID of the target pattern sequence or the ID of a second pattern sequence.

[0200] Optionally, in some embodiments, the target pattern sequence may be the first pattern sequence or the second pattern sequence, or may be a portion of the first pattern sequence or the second pattern sequence intercepted, and the intercepted range may be determined by the following parameters: information related to time domain resources, information related to frequency domain resources, and information related to space domain resources.

[0202] The information related to the frequency domain resources may include at least one of a resource element (RE) index, a resource block RB index, frequency point information, frequency band information, bandwidth, frequency domain density and subcarrier spacing.

[0203] The information related to the spatial domain resources may include at least one of an antenna port index, an antenna unit index, and an antenna panel index.

[0204] It should be noted that, when the second device receives the first information and adopts the recommendation of the terminal, the target pattern sequence can be determined through the following process:

[0205] The second device determines the first pattern sequence according to at least one of the target information value, the resource grid, and the target second mapping function, or the second device determines the second pattern sequence according to at least one of the target information value, the resource grid, and the second mapping table;

[0206] The second device determines a partial sequence in the first pattern sequence or the second pattern sequence as the target pattern sequence, or determines the first pattern sequence or the second pattern sequence as the target pattern sequence.

[0207] Optionally, in some embodiments, after the first device sends the first information to the second device, the method further includes:

[0208] The first device receives third configuration information from the second device;

[0209] The third configuration information is used to indicate whether to update at least one of the resource pattern of the target signal and the target resource pattern, and the target resource pattern is the resource pattern after the resource pattern of the target signal in the second domain is updated.

[0210] Optionally, the third configuration information includes at least one of the following:

[0211] second information, wherein the second information includes an identifier of a target second pattern sequence in a second mapping table, or a related configuration of a target second mapping function;

[0212] confirmation information, the confirmation information being used to indicate whether to agree to adjust the resource pattern of the target information in the second domain according to the first information reported by the first device;

[0213] Among them, the target second mapping function is included in the at least one candidate second mapping function, and the relevant configuration of the second mapping function is used to generate a target first pattern sequence, and the target first pattern sequence is included in at least one of the first pattern sequences; the second mapping table includes multiple candidate information values ​​and multiple second pattern sequences, and the candidate information values ​​and the second pattern sequences are mapped one by one, the target information value is included in the multiple candidate information values, and the target second pattern sequence is included in the multiple second sequences; at least a part of the target second pattern sequence or the target first pattern sequence is used to determine the target resource pattern.

[0214] Optionally, the relevant configuration of the target second mapping function includes at least one of the following:

[0215] The type of the target second mapping function;

[0216] The value of the target parameter of the target second mapping function;

[0217] The parameter type of the target parameter includes at least one of a random number seed, a probability of a specific result in a random experiment, a mean of a random experiment result, a variance of a random experiment result, and a second preset threshold.

[0218] In the embodiment of the present application, the above target parameter is included in the above candidate parameters. The value of the above target parameter may include one of the following forms:

[0219] The ID of the target parameter of the target second mapping function in the preconfigured multiple sets of candidate parameters, for example, the ID of a random number seed in the preconfigured multiple random number seeds;

[0220] The specific value of the corresponding parameter, for example, the specific value of a random number seed.

[0221] Optionally, in some embodiments, the target pattern sequence can be uniquely determined by the first information. Therefore, after the first device reports the target information value and the target indicator to the second device, the second device only needs to send a confirmation message to the first device to indicate whether the second device agrees to adjust the pattern sequence of the resource pattern according to the first information; optionally, the confirmation information can be a bit, or a bit flip.

[0222] It should be understood that the first configuration information is used to configure the resources in the time domain, frequency domain and space domain where the resource grid is located, and the second configuration information is a method for determining a candidate pattern sequence (i.e., a first pattern sequence or a second pattern sequence). The third configuration information is used to indicate a specific target pattern sequence or whether to agree to adjust the resource pattern of the target signal in the second domain according to the first information reported by the first device.

[0223] For a better understanding of the present application, some specific examples are given below for detailed description.

[0224] In some embodiments, the target information value may be determined based on the first indicator and the second indicator.

[0225] In this embodiment, the smaller the value of the first indicator (for example, it can also be called the sparsity factor), the sparser the signal is in at least one of the delay domain, Doppler domain and angle domain, that is, the fewer the sample points of the signal in at least one of the delay domain, Doppler domain and angle domain are greater than the first preset threshold; the larger the value of the second indicator, the better the signal quality.

[0226] like Figure 4 As shown, in this embodiment, there are the following settings:

[0227] Divide the possible value range of the first indicator into several intervals (seven intervals are shown in the figure, represented as S1, S2, ..., S7 from small to large);

[0228] Divide the possible value range of the second indicator into several intervals (shown in the figure are 7 intervals, represented as P1, P2, ..., P7 from small to large);

[0229] The target information value is used to indicate the amount of resources occupied by the target signal in the time domain, frequency domain, and space domain. It can take several preset values ​​(as shown in the figure, 7 values ​​can be taken, represented in descending order as M1, M2, ..., M7)

[0230] According to the above settings, the mapping relationship between the first indicator and the second indicator and the target value has the following principles:

[0231] When the second indicator takes the minimum value (i.e., the signal quality is very poor), no matter what value the first indicator takes, the target information value can only take the maximum value;

[0232] When the first index takes the maximum value (i.e., the signal sparsity is low), no matter what value the second index takes, the target information value can only take the maximum value;

[0233] Under the constraints of the first two items, given the value of the second indicator, the larger the value of the first indicator, the larger the value of the target information value;

[0234] Under the constraints of the first two items, given the value of the first indicator, the larger the value of the second indicator, the smaller the value of the target information value.

[0235] According to the above principles, after the first indicator and the second indicator are determined, the target information value can be determined by looking up a table.

[0236] based on Figure 4 The mapping relationship between the first indicator and the second indicator to the target information value can also be expressed in the form of a mapping function, which will not be repeated here.

[0237] In some embodiments, the target information value may be determined based on the first indicator.

[0238] In this embodiment, the target information value is determined only by the first indicator (eg, may also be referred to as a sparse factor).

[0239] like Figure 5 As shown, in this embodiment, there are the following settings:

[0240] Divide the possible value range of the first indicator into several intervals (seven intervals are shown in the figure, represented as S1, S2, ..., S7 from small to large);

[0241] The target information value is used to indicate the amount of resources occupied by the target signal in the time domain, frequency domain, and space domain, and can take several preset values ​​(as shown in the figure, 7 values ​​can be taken, represented in descending order as M1, M2, ..., M7);

[0242] The larger the value of the first indicator is, the larger the value of the target information value is.

[0243] based on Figure 5 The mapping relationship between the first indicator and the target information value can also be expressed in the form of a mapping function, which will not be repeated here.

[0244] Optionally, in some embodiments, the resource configuration of the target signal may be determined by a resource grid and a target resource pattern, wherein the resource configuration includes a time domain resource configuration, a frequency domain resource configuration, and a space domain resource configuration.

[0245] Among them, time domain resource configuration is mainly used in scenarios where Doppler (or speed) measurement is required in synaesthesia integration. A group of OFDM symbols are configured in the time domain to form a perception frame, which is used to perform a Doppler (or speed) measurement, satisfying: the time span of the perception frame meets the Doppler measurement resolution requirement, and the time interval between OFDM symbols in the perception frame meets the maximum unambiguous measurement range requirement of the Doppler.

[0246] like Figure 6 As shown, the configuration of CSI-RS in NR is taken as an example for explanation. The configuration parameters of CSI-RS used to determine the time domain resource grid include: firstOFDMSymbolInTimeDomain=6, CSI-ResourcePeriodicityAndOffset->slots4=0. These parameters determine that the 6th (counting from 0) OFDM symbol in the 0th slot in every 4 slots is the OFDM symbol allocated to the resource grid. The resource grid length described in the figure is 48, and the time span of the perception frame can be controlled by activating and deactivating the semi-continuous CSI-RS resources of the MAC CE to determine the length of the resource grid, or, in the subsequent process, new time span parameters for the perception frame can be added for the synaesthesia integration function.

[0247] After determining the resource grid where the target signal is located in the time domain, in this example, the target pattern sequence is generated using a random Bernoulli function. The random number seed value of the random Bernoulli function is seed=1, and the probability of "1" appearing in the random Bernoulli test is 0.4. The generated target pattern sequence is as follows: Figure 6 As shown. The OFDM symbols (resource grid n and resource grid n+2) in the resource grid corresponding to '1' in the target pattern sequence are OFDM symbols allocated to the target signal, and the OFDM symbols (resource grid n+1) in the resource grid corresponding to '0' in the target pattern sequence are OFDM symbols not allocated to the target signal (i.e., saved OFDM symbols). In this embodiment, the probability of '1' appearing in the random Bernoulli test or the random number seed can be reported by the first device to the second device as the target information value.

[0248] like Figure 7 As shown, here we take the configuration of CSI-RS in NR as an example. The configuration parameters of CSI-RS used to determine the frequency domain resource grid include: startingRB (not marked in the figure), nrofRB=48, frequencyDomainAllocation->row2='0000001000000', density=1. These parameters determine that the 6th (counting from 0) subcarrier in each RB within the specified continuous 48 RBs is the subcarrier allocated to the resource grid.

[0249] After determining the resource grid where the target signal is located in the frequency domain, in this example, the target pattern sequence is generated using a random Bernoulli function. The random number seed value of the random Bernoulli function is seed=1, and the probability of "1" appearing in the random Bernoulli test is 0.4. The generated target pattern sequence is as follows: Figure 7 As shown. The subcarriers in the resource grid corresponding to '1' in the target pattern sequence (resource grid n+1, resource grid n+2 and resource grid n+5 in the figure) are subcarriers allocated to the target signal, and the subcarriers in the resource grid corresponding to '0' in the target pattern sequence (resource grid n, resource grid n+3, resource grid n+4 and resource grid n+6 in the figure) are subcarriers not allocated to the target signal (i.e., saved subcarriers). In this embodiment, the probability of '1' appearing in the random Bernoulli test or the random number seed can be reported by the first device to the second device as the target information value.

[0250] like Figure 8 As shown, here, a dimension in the horizontal direction or numerical direction of the antenna panel is taken as an example for explanation, and the resource grid is composed of 48 continuous antenna ports or antenna units in this dimension.

[0251] After determining the resource grid where the target signal is located in the spatial domain, in this example, the target pattern sequence is generated using a random Bernoulli function. The random number seed value of the random Bernoulli function is seed=1, and the probability of "1" appearing in the random Bernoulli test is 0.4. The generated target pattern sequence is as follows: Figure 8 As shown. The resource grid corresponding to '1' in the target pattern sequence is the antenna port or antenna unit allocated to the target signal, and the resource grid corresponding to '0' in the target pattern sequence is the antenna port or antenna unit not allocated to the target signal (i.e., the saved antenna port or antenna unit). In this embodiment, the probability of '1' appearing in the random Bernoulli test or the random number seed can be reported by the first device to the second device as the target information value.

[0252] Optionally, in some embodiments, the first device may determine a target information value based on a target indicator, and report the target information value to a second device, whereupon the second device performs link adaptive adjustment of resource configuration of a target signal based on the target information value, wherein the target indicator includes a first indicator or includes a first indicator and a second indicator.

[0253] In one embodiment, if Fig. 9 As shown, the following processes may be included:

[0254] Step 901: The second device sends at least part of at least one of first configuration information and second configuration information to the first device;

[0255] Step 902, the first device determines a target indicator, and determines a target information value according to the target indicator;

[0256] Step 903: The first device sends a target information value to the second device;

[0257] Step 904, the second device determines and performs link adaptive adjustment;

[0258] Step 905: The second device sends third configuration information to the first device.

[0259] In one embodiment, if Fig.10 As shown, the following processes may be included:

[0260] Step 1001: The second device sends at least part of at least one of first configuration information and second configuration information to the first device;

[0261] Step 1002, the first device determines a target indicator;

[0262] Step 1003, the first device sends the target indicator to the second device;

[0263] Step 1004, the second device determines the target information value, determines and performs link adaptive adjustment;

[0264] Step 1005: The second device sends third configuration information to the first device.

[0265] against Fig. 9 and Fig.10 , the first device and the second device may include any of the following:

[0266] Case 1: the first device is a terminal, and the second device is an access network device or a core network device (such as a perception function network element);

[0267] Case 2: the first device is terminal 1, and the second device is terminal 2;

[0268] Case 3: the first device is an access network device, and the second device is a core network device;

[0269] Case 4: the first device is access network device 1, and the second device is access network device 2.

[0270] Optionally, some of the above situations (such as situation 1) are applicable to communication scenarios, and all of the situations are applicable to synaesthesia scenarios.

[0271] Optionally, in some embodiments, adaptive adjustment is performed in the frequency domain.

[0272] The channel is sparse in the delay domain. By utilizing the sparsity of the channel in the delay domain, the target signal can be sparsely configured in the frequency domain according to the signal configuration adaptive processing method of the present application to save the frequency domain resource overhead of the target signal. The target signal can be: a reference signal in communication, or a perception signal in synaesthesia integration. The basic idea is: based on the results of channel measurement, the link adaptively selects a part of subcarriers from the configured frequency domain resources for the configuration of the target signal, and the unselected subcarriers are saved. Among them, the configured frequency domain resources can be understood as the above-mentioned resource grid or a part of the resource grid.

[0273] The first device measures the target signal to obtain the target indicator, which includes the first indicator, or includes the first indicator and the second indicator; wherein the first indicator may be the number of sample points exceeding the first preset threshold in the delay domain, or the first indicator is other indicators related to the number of sample points exceeding the first preset threshold in the delay domain. For example, the value range of the number of sample points exceeding the first preset threshold in the delay domain may be divided into several intervals, each interval corresponding to an ID, and the first indicator is the ID corresponding to the interval into which the actually measured number of sample points exceeding the first preset threshold in the delay domain falls.

[0274] In some implementations, the first device feeds back the target indicator to the second device via signaling, and the second device determines the target information value based on an algorithm, and then determines the target pattern sequence, and notifies the first device of the target pattern sequence (i.e., the third configuration information). Afterwards, the subcarriers corresponding to the target pattern sequence of '1' in the configured frequency domain resources (i.e., the resource grid) still send the target signal, while the subcarriers corresponding to the target pattern sequence of '0' in the configured frequency domain resources (i.e., the resource grid) do not send the target signal.

[0275] In other embodiments, the first device determines the target information value according to the target indicator, and then determines the target pattern sequence. Prior to this, the second device needs to configure the method for determining the target information value and the target pattern sequence to the first device (i.e., the second configuration information). After the first device determines the target information value, it feeds back the target information value to the second device through signaling. Since the target information value is uniquely corresponding to the target pattern sequence, the second device can obtain the target pattern sequence recommended by the first device after obtaining the target information value. The second device can choose to adopt the target pattern sequence corresponding to the target information value, or not to adopt the target pattern sequence corresponding to the target information value. If the second device adopts the target pattern sequence, the subcarrier corresponding to the target pattern sequence of '1' in the configured frequency domain resources (i.e., the resource grid) still sends the target signal, while the subcarrier corresponding to the target pattern sequence of '0' in the configured frequency domain resources (i.e., the resource grid) does not send the target signal. The second device can indicate to the first device whether the second device has adopted the recommended target pattern sequence through a simple confirmation message (i.e., the third configuration information), for example: the confirmation message can be a 1-bit message. After receiving the confirmation information, the first device knows whether the second device adopts the target pattern sequence. If the second device adopts the target pattern sequence, the first device receives the target signal according to the frequency domain resource configuration of the target signal determined by the target pattern sequence, otherwise the first device receives the target signal according to the previous configuration.

[0276] like Fig.11 As shown, it is a schematic diagram of sparse configuration of the target signal using the solution of the present application, taking 32-port CSI-RS as an example. After link adaptive adjustment of the frequency domain resources of the target signal according to the target pattern sequence, in the configured frequency domain resources (i.e., the resource grid), the subcarriers in the resource grid corresponding to '1' in the right target pattern sequence still have CSI-RS transmission (such as the parts filled with various patterns in the figure below), while the subcarriers in the resource grid corresponding to '0' in the right target pattern sequence have no CSI-RS transmission (such as the gray filled parts in the figure below).

[0277] Optionally, in some embodiments, adaptive adjustment is performed in the time domain.

[0278] The channel is sparse in the Doppler domain. By utilizing the sparsity of the channel in the Doppler domain, the target signal can be sparsely configured in the time domain according to the signal configuration adaptive processing method of the present application to save the time domain resource overhead of the target signal. The target signal can be: a reference signal in communication, or a perception signal in synaesthesia integration. In fact, only scatterers with relative motion between the transceiver device of the target signal will produce a Doppler frequency shift on the target signal; therefore, the sparsity of the channel in the Doppler domain is usually high. The basic idea is: according to the results of the channel measurement, the link adaptively selects a part of the OFDM symbols from the configured time domain resources for the configuration of the target signal, and the unselected OFDM symbols are saved. Among them, the configured frequency domain resources can be understood as the above-mentioned resource grid or a part of the resource grid.

[0279] The first device measures the target signal to obtain the target index, which includes the first index, or includes the first index and the second index; wherein the first index may be the number of sample points exceeding the first preset threshold in the Doppler domain, or the first index is other indexes related to the number of sample points exceeding the first preset threshold in the delay domain. For example, the value range of the number of sample points exceeding the first preset threshold in the delay domain may be divided into several intervals, each interval corresponding to an ID, and the first index is the ID corresponding to the interval into which the number of sample points exceeding the first preset threshold in the delay domain actually measured falls.

[0280] The process of adaptive adjustment is as follows: Fig.11 The embodiments shown are similar and will not be described again here.

[0281] like Fig.12 As shown, it is a schematic diagram of sparse configuration of target signals using the solution of the present application. Fig.11 The difference between the examples shown is that this embodiment is applied in the time domain, which is similar to the application in the frequency domain and will not be repeated here. Fig.12 The time domain period of the target signal is 1 time slot for the convenience of drawing.

[0282] Optionally, in some embodiments, adaptive adjustment is performed in the spatial domain.

[0283] The sparsity of the channel in the angle domain, especially in MIMO scenarios with a large number of ports (for example: mMIMO, el-MIMO), can complete channel estimation by transmitting reference signals of some ports according to the signal configuration adaptive processing method of the present application, without the need for each port to transmit the target signal, thereby saving at least one of the overhead of time-frequency resources and the overhead of antenna ports. The target signal can be: a reference signal in communication, or a perception signal in synaesthesia integration. The basic idea is: according to the result of channel measurement, a part of antenna ports are adaptively selected from the configured spatial domain resources (antenna ports) for the configuration of the target signal, and the unselected antenna ports are saved. Among them, the spatial domain resources configured according to the prior art method are the resource grids described in the technical solution part. Since some antenna ports do not need to send target signals, the time-frequency domain resource overhead occupied by the target signal is correspondingly reduced. In addition, in synaesthesia integration applications, ports that do not send perception signals can be closed or used for other services.

[0284] The first device measures the target signal to obtain a target indicator, wherein the target indicator includes a first indicator, or includes a first indicator and a second indicator; wherein the first indicator may be the number of sample points exceeding a first preset threshold in the angle domain, or the first indicator is another indicator related to the number of sample points exceeding the first preset threshold in the delay domain. For example, the value range of the number of sample points exceeding the first preset threshold in the delay domain may be divided into several intervals, each interval corresponding to an ID, and the first indicator is the ID corresponding to the interval into which the number of sample points exceeding the first preset threshold in the delay domain actually measured falls.

[0285] The process of adaptive adjustment is as follows: Fig.11 The embodiments shown are similar and will not be described again here.

[0286] like Fig.13As shown, it is a schematic diagram of sparse configuration of the target signal using the scheme of the present application, still taking 32-port CSI-RS as an example. There is still CSI-RS transmission in the port corresponding to '1' in the target pattern sequence, and there is no CSI-RS transmission in the port corresponding to '0' in the target pattern sequence. Before adopting the scheme of the present application, the 32 ports allocated to CSI-RS constitute 4 code division multiplexing (Code Division Multiplexing, CDM) groups, and each CDM group contains 8 ports. In a certain link adaptation process, according to the channel measurement results, only 16 ports are needed to realize the channel estimation of the entire angle domain, and the 16 ports are determined by the target pattern sequence in the original 32 ports. For example, 6, 3, 3, and 4 ports of the previous 4 CDM groups are selected by the target pattern sequence to form 2 new CDM groups, namely CDM group5 and CDM group6 in the figure. CDM group 5 and CDM group 6 occupy the original resources of CDM group 1 and CDM group 2 in the time and frequency domain, thereby saving the original time and frequency resources of CDM group 3 and CDM group 4 (the gray filled part in the figure below).
