[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410052585.5 filed in China on January 12, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure belongs to the field of wireless transmission technology, and in particular relates to a method, apparatus, device, and storage medium for processing channel parameters. Background Art

[0004] In related technologies, when training an artificial intelligence (AI) model based on channel measurement data from user equipment (UE), it is necessary to collect a large amount of channel measurement data and transmit the collected large amount of channel measurement data to network-side equipment, which increases data collection and air interface transmission overhead. Summary of the Invention

[0005] Embodiments of the present disclosure provide a method, apparatus, device, and storage medium for processing channel parameters.

[0006] An embodiment of the present disclosure provides a method for processing channel parameters, which is applied to a UE. The method includes:

[0007] Receiving configuration information sent by a network-side device, where the configuration information includes at least channel parameters that the UE needs to report and a reporting method of the UE;

[0008] According to the channel parameters that the UE needs to report and the reporting mode of the UE, the channel parameters are reported to the network side device.

[0009] In some embodiments, the channel parameters that the UE needs to report include one or more of the following parameters: multipath delay extension value, multipath transmission horizontal angle extension value, multipath reception horizontal angle extension value, multipath transmission vertical angle extension value, multipath reception vertical angle extension value, cluster quantity data analysis statistical value, intra-cluster multipath delay extension value, intra-cluster multipath transmission horizontal angle extension value, intra-cluster multipath reception horizontal angle extension value, intra-cluster multipath transmission vertical angle extension value, intra-cluster multipath reception vertical angle extension value, Rice factor, and Doppler frequency shift.

[0010] It can be seen that the UE can report the corresponding channel parameters to the network side according to the configuration information sent by the network side device, thereby helping to meet the needs of the network side device to receive channel parameters.

[0011] In some embodiments, the UE's reporting method includes: an event-triggered reporting method or a periodic reporting method. It can be seen that the UE can use a flexible reporting method to report channel parameters to the network-side device based on the event-triggered reporting method or the periodic reporting method in the configuration information sent by the network-side device, which is conducive to meeting the network-side device's need to receive channel parameters.

[0012] In some embodiments, the configuration information includes the type of event used to trigger the UE to report the channel parameters or the period for the UE to report the channel parameters. In this way, since the type of event used to trigger the UE to report the channel parameters or the period for the UE to report the channel parameters are content in the configuration information sent by the network side, when the UE reports the channel parameters to the network side device based on the type of event used to trigger the UE to report the channel parameters or the period for the UE to report the channel parameters, the network side device's need to receive the channel parameters can be met.

[0013] In some embodiments, the reporting of the channel parameters to the network side device based on the channel parameters that the UE needs to report and the reporting method of the UE includes: when the reporting method of the UE includes an event-triggered reporting method, when an event that triggers the UE to report the channel parameters occurs, reporting the channel parameters to the network side device; or, when the reporting method of the UE includes a periodic reporting method, reporting the channel parameters to the network side device according to the period of the UE reporting the channel parameters. It can be seen that the UE can report the channel parameters to the network side device at an appropriate time based on the event-triggered reporting method or the periodic reporting method in the configuration information sent by the network side device, which is conducive to meeting the needs of the network side device to receive channel parameters.

[0014] In some embodiments, the channel parameters that the UE needs to report are data analysis results of the channel; before reporting the channel parameters to the network side device based on the channel parameters that the UE needs to report and the reporting method of the UE, the method also includes: performing channel measurement according to the channel parameters that the UE needs to report to obtain channel measurement data; extracting parameters of the channel measurement data; performing data analysis on the parameters of the channel measurement data to obtain data analysis results of the channel.

[0015] It can be seen that the channel parameters that the UE needs to report are obtained by analyzing the parameters of the channel measurement data. Therefore, the channel parameters that the UE needs to report are consistent with the channel propagation characteristics of the actual measurement scenario, which is conducive to the application of channel parameters by network-side devices for channel simulation.

[0016] In some embodiments, the parameters of the channel measurement data include one or more of the following parameters: multipath transmission horizontal angle, multipath transmission vertical angle, multipath reception horizontal angle, multipath reception vertical angle, multipath power, multipath delay, number of clusters, intra-cluster multipath delay, intra-cluster multipath transmission horizontal angle, intra-cluster multipath transmission vertical angle, intra-cluster multipath reception horizontal angle, intra-cluster multipath reception vertical angle, intra-cluster multipath power, and intra-cluster multipath delay.

[0017] It can be seen that the UE can obtain the channel parameters that the UE needs to report by performing data analysis on multipath transmission parameters, multipath reception parameters, multipath power, multipath delay, number of clusters, intra-cluster multipath parameters, etc. That is, the UE only needs to report a small amount of channel parameters to the network side device, and does not need to report a large amount of channel measurement data to the network side device, thereby reducing data collection and air interface transmission overhead.

[0018] The present disclosure also provides another method for processing channel parameters, which is applied to a network-side device and includes:

[0019] Sending configuration information to the UE, where the configuration information includes at least channel parameters that the UE needs to report and a reporting mode of the UE;

[0020] Receive the channel parameters reported by the UE according to the channel parameters required to be reported by the UE and the reporting mode of the UE.

[0021] In some embodiments, the channel parameters that the UE needs to report include one or more of the following parameters: multipath delay extension value, multipath transmission horizontal angle extension value, multipath reception horizontal angle extension value, multipath transmission vertical angle extension value, multipath reception vertical angle extension value, cluster quantity data analysis statistical value, intra-cluster multipath delay extension value, intra-cluster multipath transmission horizontal angle extension value, intra-cluster multipath reception horizontal angle extension value, intra-cluster multipath transmission vertical angle extension value, intra-cluster multipath reception vertical angle extension value, Rice factor, Doppler frequency shift; or, the reporting method of the UE includes: event-triggered reporting method or periodic reporting method.

[0022] As can be seen, the UE can report the corresponding channel parameters to the network side based on the configuration information sent by the network side device, thereby helping to meet the needs of the network side device to receive channel parameters. The UE can use a flexible reporting method to report channel parameters to the network side device based on the event-triggered reporting method or periodic reporting method in the configuration information sent by the network side device, which helps to meet the needs of the network side device to receive channel parameters.

[0023] In some embodiments, the configuration information further includes one or more of the following information: the type of event used to trigger the UE to report the channel parameters, and the period for the UE to report the channel parameters. In this way, since the type of event used to trigger the UE to report the channel parameters or the period for the UE to report the channel parameters are content in the configuration information sent by the network side, when the UE reports the channel parameters to the network side device based on the type of event used to trigger the UE to report the channel parameters or the period for the UE to report the channel parameters, the requirement of the network side device to receive the channel parameters can be met.

[0024] In some embodiments, after receiving the channel parameters reported by the UE according to the channel parameters required to be reported by the UE and the reporting method of the UE, the method further includes: applying the channel parameters to perform channel simulation to generate channel simulation data.

[0025] It can be seen that the channel simulation data is obtained by simulating the channel parameters reported by the UE, and the channel parameters reported by the UE are obtained by analyzing the parameters of the measured channel measurement data. Therefore, the channel simulation data can conform to the channel propagation characteristics of the measured scenario, and the channel parameters reported by the UE are not equivalent to the original channel measurement data. Therefore, compared with the channel measurement data, the channel simulation data obtained by simulating the channel parameters reported by the UE increases the diversity of the data. Furthermore, when constructing the training data of the neural network based on the channel simulation data, the training data of the neural network can have a certain degree of randomness and generalization ability, which is conducive to improving the training accuracy of the neural network and the generalization ability of the trained neural network.

[0026] The embodiment of the present disclosure further provides a channel parameter processing device, which is applied to a UE and includes:

[0027] A first receiving module is configured to receive configuration information sent by a network-side device, where the configuration information includes at least channel parameters that the UE needs to report and a reporting mode of the UE;

[0028] The first sending module is used to report the channel parameters to the network side device according to the channel parameters that the UE needs to report and the reporting mode of the UE.

[0029] The present disclosure also provides another channel parameter processing device, which is applied to a network-side device and includes:

[0030] A second sending module, configured to send configuration information to a user equipment UE, where the configuration information includes at least channel parameters that the UE needs to report and a reporting mode of the UE;

[0031] The second receiving module is used to receive the channel parameters reported by the UE according to the channel parameters required to be reported by the UE and the reporting mode of the UE.

[0032] An embodiment of the present disclosure also provides a user equipment, which includes a processor and a memory for storing a computer program that can be run on the processor; wherein the processor is used to run the computer program to execute any of the above-mentioned channel parameter processing methods applied to the UE.

[0033] An embodiment of the present disclosure also provides a network side device, which includes a processor and a memory for storing a computer program that can be run on the processor; wherein the processor is used to run the computer program to execute any of the above-mentioned channel parameter processing methods applied to the network side device.

[0034] An embodiment of the present disclosure further provides a computer storage medium storing a computer program, which implements any of the above-mentioned channel parameter processing methods when executed by a processor.

[0035] An embodiment of the present disclosure further provides a computer program product, including computer instructions, which implement any of the above-mentioned channel parameter processing methods when executed by a processor.

[0036] It can be seen that in the embodiment of the present disclosure, the UE can report the channel parameters to the network side according to the channel parameters that the UE needs to report in the configuration information, that is, the channel parameters reported by the UE are determined according to the configuration information sent by the network side. Therefore, it is only necessary to reasonably collect channel measurement data according to the sent configuration information to obtain the corresponding channel parameters. There is no need to collect a large amount of channel measurement data, which is beneficial to reducing data collection and air interface transmission overhead. In addition, the UE can also report the channel parameters to the network side device according to the reporting method of the UE in the configuration information, which is beneficial to reducing the air interface transmission overhead of the channel parameters.

[0045] The 3rd Generation Partnership Project (3GPP) is currently discussing an AI-based channel state information (CSI) compression feedback solution for frequency division duplexing (FDD) systems, including the AI ​​model training process and the AI ​​model inference process. Since training AI models requires a large amount of training data, for example, a large amount of channel measurement data needs to be collected for training AI models.

[0046] In actual scenarios, the collection of measured data such as channel measurement data will incur huge collection overhead and air interface transmission overhead. At the same time, when retraining the AI ​​model, it will incur repeated data collection overhead.

[0047] In order to solve the above technical problems, a technical solution of the embodiment of the present disclosure is proposed.

[0048] The following is a further detailed description of the embodiments of the present disclosure in conjunction with the accompanying drawings and examples. It should be understood that the embodiments provided herein are merely for explaining the embodiments of the present disclosure and are not intended to limit the embodiments of the present disclosure. In addition, the embodiments provided below are partial embodiments for implementing the present disclosure, rather than providing all embodiments for implementing the present disclosure. In the absence of conflict, the technical solutions described in the embodiments of the present disclosure may be implemented in any combination.

[0049] It should be noted that, in the embodiments of the present disclosure, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a method or apparatus comprising a series of elements includes not only the elements explicitly stated, but also other elements not explicitly listed, or also includes elements inherent to the implementation of the method or apparatus. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other related elements (such as steps in the method or units in the apparatus, for example, a unit may be a portion of a circuit, a portion of a processor, a portion of a program or software, etc.) in the method or apparatus comprising the element.

[0050] The channel parameter processing method provided by the embodiment of the present disclosure includes a series of steps, but the channel parameter processing method provided by the embodiment of the present disclosure is not limited to the recorded steps. Similarly, the channel parameter processing device provided by the embodiment of the present disclosure includes a series of modules, but the device provided by the embodiment of the present disclosure is not limited to including the modules explicitly recorded, and can also include modules that need to be set up for obtaining relevant information or performing processing based on information.

[0051] FIG1 is a flow chart of a method for processing channel parameters applied to a UE according to an embodiment of the present disclosure. As shown in FIG1 , the process may include:

[0052] Step 101: Receive configuration information sent by a network-side device, where the configuration information at least includes channel parameters that the UE needs to report and a reporting method of the UE.

[0053] In the embodiment of the present disclosure, the network side device may be a base station (BS), a core network element, etc. Before collecting the channel parameters of the UE, the network side device may send configuration information to the UE.

[0054] For example, the network side device can configure the channel measurement data that the UE needs to measure and the channel parameters that the UE needs to report based on the UE's capability information. Here, the capability information required by the UE may include one or more of the following parameters: working bandwidth, number of transmitting and receiving antennas, and parameters that characterize whether users and scatterers within the coverage area are moving significantly.

[0055] Step 102: Report the channel parameters to the network side device according to the channel parameters that the UE needs to report and the reporting mode of the UE.

[0056] Here, after receiving the configuration information, the UE can obtain the channel parameters that the UE needs to report by collecting and processing channel measurement data based on the channel parameters that the UE needs to report in the configuration information. The UE can report the channel parameters to the network side device according to the UE reporting method.

[0057] In actual applications, steps 101 to 102 can be implemented based on the processor of the UE, and the above-mentioned processor can be at least one of an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a field programmable gate array (FPGA), a central processing unit (CPU), a controller, a microcontroller, and a microprocessor.

[0058] It can be seen that in the embodiment of the present disclosure, the UE can report the channel parameters to the network side according to the channel parameters that the UE needs to report in the configuration information, that is, the channel parameters reported by the UE are determined according to the configuration information sent by the network side. Therefore, it is only necessary to reasonably collect channel measurement data according to the sent configuration information to obtain the corresponding channel parameters. There is no need to collect a large amount of channel measurement data, which is beneficial to reducing data collection and air interface transmission overhead. In addition, the UE can also report the channel parameters to the network side device according to the reporting method of the UE in the configuration information, which is beneficial to reducing the air interface transmission overhead of the channel parameters.

[0059] In some embodiments of the present disclosure, the channel parameters that the UE needs to report include one or more of the following parameters: multipath delay extension value, multipath transmission horizontal angle extension value, multipath reception horizontal angle extension value, multipath transmission vertical angle extension value, multipath reception vertical angle extension value, cluster quantity data analysis statistical value, intra-cluster multipath delay extension value, intra-cluster multipath transmission horizontal angle extension value, intra-cluster multipath reception horizontal angle extension value, intra-cluster multipath transmission vertical angle extension value, intra-cluster multipath reception vertical angle extension value, Rice factor, and Doppler frequency shift.

[0060] Here, the multipath delay spread value is obtained by performing data analysis on the multipath delay; the multipath transmission horizontal angle spread value, the multipath reception horizontal angle spread value, the multipath transmission vertical angle spread value, and the multipath reception vertical angle spread value are respectively obtained by performing data analysis on the multipath transmission horizontal angle, the multipath reception horizontal angle, the multipath transmission vertical angle, and the multipath reception vertical angle; the intra-cluster multipath delay spread value, the intra-cluster multipath transmission horizontal angle spread value, the intra-cluster multipath reception horizontal angle spread value, the intra-cluster multipath transmission vertical angle spread value, and the intra-cluster multipath reception vertical angle spread value are respectively obtained by performing data analysis on the intra-cluster multipath delay, the intra-cluster multipath transmission horizontal angle, the intra-cluster multipath reception horizontal angle, the intra-cluster multipath transmission vertical angle, and the intra-cluster multipath reception vertical angle; the Rice factor, also known as the Rice K factor, is an important parameter that characterizes the degree of channel fading.

[0061] The cluster quantity data analysis statistic is obtained by performing data analysis on the cluster quantity data; in some embodiments, the cluster quantity data analysis statistic is obtained by fitting the cluster quantity, for example, a random distribution such as Gaussian distribution or Laplace distribution can be used to fit the cluster quantity to obtain the cluster quantity data analysis statistic.

[0062] It can be seen that the UE can report the corresponding channel parameters to the network side according to the configuration information sent by the network side device, thereby helping to meet the needs of the network side device to receive channel parameters.

[0063] In some embodiments of the present disclosure, the channel parameter that the UE needs to report is a data analysis result of the channel.

[0064] Accordingly, before reporting the channel parameters to the network side device according to the channel parameters that the UE needs to report and the reporting method of the UE, the method also includes: performing channel measurement according to the channel parameters that the UE needs to report to obtain channel measurement data; extracting parameters of the channel measurement data; performing data analysis on the parameters of the channel measurement data to obtain channel data analysis results.

[0065] Exemplarily, the UE may acquire representative measured data by collecting channel measurement data; and the process of the UE collecting channel measurement data may be implemented through Minimization Drive Test (MDT).

[0066] Exemplarily, when a UE collects channel measurement data through MDT, the MDT process can be appropriately adjusted. In one example, measurement quantities can be added to immediate MDT or logged MDT. Here, immediate MDT refers to MDT performed by the UE in a connected state, and when logged MDT refers to MDT performed by the UE in an idle state or inactive state, appropriate adjustments can be made to logged MDT so that the UE can perform the logged MDT process in the connected state.

[0067] For example, the measurement quantities added to the immediate MDT include: multipath angle delay spread measurement by UE, multipath delay spread measurement by UE, cluster number measurement by UE, and intra cluster parameter measurement by UE; the measurement quantities added to the logged MDT include multipath angle delay spread measurement by UE, multipath delay spread value (angle delay measurement by UE), cluster number measurement by UE, and intra cluster parameter.

[0068] Here, the intra-cluster parameter may include one or more of the following parameters: an intra-cluster delay spread value, an intra-cluster angle spread value, and a cluster quantity variance.

[0069] Exemplarily, the channel measurement data may be a frequency domain channel matrix H(f) or a time domain channel matrix H(t), where H(f)=N r *N t *N sb , where N r is the number of receiving antenna ports, N t is the number of transmitting antenna ports, N sb is the number of subbands; H(t) = N r *N t *N tau , where N tau is the delay number.

[0070] Signal processing can be performed on the frequency domain channel matrix H(f) or the time domain channel matrix H(t) to obtain the parameters of the channel measurement data. For example, when modeling the channel, it is necessary to apply the Channel Impulse Response (CIR) to extract the angle information, but commercial terminals cannot obtain the CIR. In the embodiment of the present disclosure, multipath angle information can be obtained by transforming the port domain to the angle domain. In one example, a two-dimensional discrete Fourier transform (DFT) can be performed on the frequency domain channel matrix H(f) to obtain the matrix H(s). In this way, the frequency domain channel matrix can be transformed into the multipath angle domain of the receiving end and the transmitting end. The matrix H(s) = U H *H(f)*V, where U is the size of N r *N r The spatial domain beam basis vector, V is the size of N t *N t The spatial domain beam basis vectors are , and the superscript H represents the conjugate transpose.

[0071] It can be seen that the size of H(s) is N r *N t *N sb If you need to get the receiving end angle, just stack H(s) to N r dimension; for example, we can first calculate H(s) in N sb Dimensions are summed, and then, for N sb The sum of the dimensions is N t By summing the dimensions, we can get the angle information of the receiving end.

[0072] For example, the multipath delay can be extracted according to the delay channel, and then the multipath power information can be extracted according to formula (1). n )=||h(τ n )|| 2 ,n=1,...,N (1)

[0073] Among them, h(τ n ) represents the time domain channel matrix, τ n represents the delay of the nth multipath, P(τ n ) is the power of the nth multipath, and N is the number of multipaths.

[0074] Illustratively, the method for extracting the intra-cluster multipath delay is similar to the method for extracting the multipath delay, and the method for extracting the intra-cluster multipath angle is similar to the method for extracting the multipath angle, which will not be described in detail here.

[0075] Exemplarily, after extracting the parameters of the channel measurement data, a data analysis result of the channel can be obtained by performing a statistical feature analysis on the parameters of the channel measurement data. In one example, the data analysis result of the channel can include a multipath angle spread value, a multipath delay spread value, and a cluster number data statistical analysis value. Here, the multipath angle spread value can be a multipath transmission horizontal angle spread value, a multipath reception horizontal angle spread value, a multipath transmission vertical angle spread value, or a multipath reception vertical angle spread value. The multipath angle spread value σ can be calculated according to formula (2). AS .

[0076] Where L represents the number of channel multipaths, P l represents the multipath power of the lth channel, θ l,u It represents the angle difference between the multipath angle of the lth channel and the mean angle.

[0077] The multipath delay spread value τ can be calculated according to formula (3): rms .

[0078] Among them, τ l represents the multipath delay of the lth channel, τ mean Indicates the mean multipath delay.

[0079] Cluster is a parameter that characterizes the spatial scattering of a channel. The related art TR 38.901 text describes a general channel scenario, so the number of clusters is described as a fixed number. Since there are a large number of variable scatterers in real scenarios, such as pedestrians and moving vehicles, the number of clusters can be fitted to characterize the ever-changing spatial environment characteristics of mobile communications and generate channel characteristics corresponding to specific scenarios. For example, a random distribution such as a Gaussian distribution or a Laplace distribution can be used to fit the number of clusters, resulting in a random fitting value for the number of clusters. This fitting value for the number of clusters is the statistical value of the cluster number data analysis described above. The fitting value for the number of clusters can more completely characterize fixed scatterers in space, such as buildings and trees, as well as mobile clusters closer to the receiver, such as a random number of pedestrians and vehicles. When training a neural network based on training data obtained from the fitting value for the number of clusters, the trained neural network can have stronger generalization capabilities.

[0080] It can be seen that the channel parameters that the UE needs to report are obtained by analyzing the parameters of the channel measurement data. Therefore, the channel parameters that the UE needs to report are consistent with the channel propagation characteristics of the actual measurement scenario, which is conducive to the application of channel parameters by network-side devices for channel simulation.

[0081] In some embodiments of the present disclosure, the parameters of the channel measurement data include one or more of the following parameters: multipath transmission horizontal angle, multipath transmission vertical angle, multipath reception horizontal angle, multipath reception vertical angle, multipath power, multipath delay, number of clusters, intra-cluster multipath delay, intra-cluster multipath transmission horizontal angle, intra-cluster multipath transmission vertical angle, intra-cluster multipath reception horizontal angle, intra-cluster multipath reception vertical angle, intra-cluster multipath power, and intra-cluster multipath delay.

[0082] It can be seen that the UE can obtain the channel parameters that the UE needs to report by performing data analysis on multipath transmission parameters, multipath reception parameters, multipath power, multipath delay, number of clusters, intra-cluster multipath parameters, etc. That is, the UE only needs to report a small amount of channel parameters to the network side device, and does not need to report a large amount of channel measurement data to the network side device, thereby reducing data collection and air interface transmission overhead.

[0083] In some embodiments of the present disclosure, the reporting method of the UE includes: an event-triggered reporting method or a periodic reporting method.

[0084] Exemplarily, an event-triggered reporting method can be added to Immediate MDT. When an event-triggered reporting method is added to Immediate MDT, the event used to trigger the UE to report channel parameters may include one or more of the following events: end of the channel measurement process (End of measurement quantity), and the target object of the channel measurement is out of the detection range (out-of-coverage detection trigger).

[0085] Exemplarily, when the UE reports channel parameters using an event-triggered reporting method or a periodic reporting method, all channel parameters may be reported with high precision, or differential reporting of classic values ​​based on TR 38.901, or differential reporting based on maximum and minimum values, or reporting according to precision requirements. For example, one implementation of reporting according to precision requirements is: for parameters with higher precision requirements, such as multipath parameters, a high-precision (floating point value float32 / float16) reporting method is used for reporting, and for parameters with lower precision requirements, such as cluster parameters, a lower-precision reporting method, such as a quantized reporting method, is used for reporting.

[0086] It can be seen that the UE can use a flexible reporting method to report channel parameters to the network side device based on the event-triggered reporting method or periodic reporting method in the configuration information sent by the network side device, which is conducive to meeting the needs of the network side device to receive channel parameters.

[0087] In some embodiments of the present disclosure, the configuration information may include the type of event used to trigger the UE to report channel parameters or the period for the UE to report channel parameters. In this way, since the type of event used to trigger the UE to report channel parameters or the period for the UE to report channel parameters are included in the configuration information sent by the network side, when the UE reports the channel parameters to the network side device based on the type of event used to trigger the UE to report channel parameters or the period for the UE to report channel parameters, the network side device's requirement for receiving the channel parameters can be met.

[0088] In some embodiments of the present disclosure, based on the channel parameters that the UE needs to report and the reporting method of the UE, the process of reporting the channel parameters to the network side device may include: when the reporting method of the UE includes an event-triggered reporting method, when an event for triggering the UE to report the channel parameters occurs, reporting the channel parameters to the network side device; or, when the reporting method of the UE includes a periodic reporting method, reporting the channel parameters to the network side device according to the period of the UE reporting the channel parameters. It can be seen that the UE can report the channel parameters to the network side device at an appropriate time according to the event-triggered reporting method or the periodic reporting method in the configuration information sent by the network side device, which is conducive to meeting the needs of the network side device to receive channel parameters.

[0089] FIG2 is a flow chart of a method for processing channel parameters applied to a network-side device according to an embodiment of the present disclosure. As shown in FIG2 , the process may include:

[0090] Step 201: Send configuration information to the UE, where the configuration information at least includes channel parameters that the UE needs to report and the reporting mode of the UE.

[0091] Step 202: Receive the channel parameters reported by the UE according to the channel parameters required to be reported by the UE and the reporting mode of the UE.

[0092] In practical applications, steps 201 to 202 may be implemented based on a processor of a network-side device, which may be one or more of an ASIC, a DSP, a DSPD, a PLD, an FPGA, a CPU, a controller, a microcontroller, and a microprocessor.

[0093] It can be seen that in the embodiment of the present disclosure, the UE can report the channel parameters to the network side according to the channel parameters that the UE needs to report in the configuration information, that is, the channel parameters reported by the UE are determined according to the configuration information sent by the network side. Therefore, it is only necessary to reasonably collect channel measurement data according to the sent configuration information to obtain the corresponding channel parameters. There is no need to collect a large amount of channel measurement data, which is beneficial to reducing data collection and air interface transmission overhead. In addition, the UE can also report the channel parameters to the network side device according to the reporting method of the UE in the configuration information, which is beneficial to reducing the air interface transmission overhead of the channel parameters.

[0094] In some embodiments of the present disclosure, the channel parameters that the UE needs to report include one or more of the following parameters: multipath delay spread value, multipath transmission horizontal angle spread value, multipath reception horizontal angle spread value, multipath transmission vertical angle spread value, multipath reception vertical angle spread value, cluster quantity data analysis statistics, intra-cluster multipath delay spread value, intra-cluster multipath transmission horizontal angle spread value, intra-cluster multipath reception horizontal angle spread value, intra-cluster multipath transmission vertical angle spread value, intra-cluster multipath reception vertical angle spread value, Rice factor, Doppler shift;

[0095] Alternatively, the reporting method of the UE includes: an event-triggered reporting method or a periodic reporting method.

[0096] As can be seen, the UE can report the corresponding channel parameters to the network side based on the configuration information sent by the network side device, thereby helping to meet the needs of the network side device to receive channel parameters. The UE can use a flexible reporting method to report channel parameters to the network side device based on the event-triggered reporting method or periodic reporting method in the configuration information sent by the network side device, which helps to meet the needs of the network side device to receive channel parameters.

[0097] In some embodiments of the present disclosure, the configuration information further includes one or more of the following information: the type of event used to trigger the UE to report the channel parameters, and the period for the UE to report the channel parameters. In this way, since the type of event used to trigger the UE to report the channel parameters or the period for the UE to report the channel parameters are included in the configuration information sent by the network side, when the UE reports the channel parameters to the network side device based on the type of event used to trigger the UE to report the channel parameters or the period for the UE to report the channel parameters, the network side device's need to receive the channel parameters can be met.

[0098] In some embodiments of the present disclosure, after receiving the channel parameters reported by the UE according to the channel parameters required to be reported by the UE and the reporting method of the UE, the method further includes: applying the channel parameters to perform channel simulation to generate channel simulation data.

[0099] For example, the channel parameters received by the network-side device can be input into a standard simulation platform such as the 3GPP TR 38.901 simulation platform, thereby updating the platform parameters of the simulation platform; the simulation platform with updated platform parameters is used to generate channel simulation data, which is similar to the channel measurement data and is an enhanced data set of the channel measurement data.

[0100] For example, referring to FIG3 , in the process of generating channel simulation data in the simulation platform, parameter configuration information such as the scenario, network layout, and antenna can be set, and propagation conditions can be set. Then, path loss can be calculated, large-scale parameters and small-scale parameters can be generated, a random initial phase can be generated, channel coefficients can be generated, and path and shadow fading can be superimposed. For example, the propagation condition can be non-line of sight (NLoS) or line of sight (LoS); large-scale parameters can include one or more of the following parameters: delay spread (DS) related parameters, angle spread (AS) related parameters, shadow fading (SF) related parameters, Rice factor, Doppler shift; small-scale parameters can include one or more of the following parameters: cluster delay, cluster power, arrival angle, departure angle, intra-cluster sub-path matching, and cross polarization ratio (XPR).

[0101] Exemplarily, the large-scale parameters shown in FIG. 3 and other parameters may be updated according to the channel parameters received by the network-side device. These updated parameters may affect the generation of parameters such as channel multipath power and channel multipath angle.

[0102] It can be seen that the channel simulation data is obtained by simulating the channel parameters reported by the UE, and the channel parameters reported by the UE are obtained by analyzing the parameters of the measured channel measurement data. Therefore, the channel simulation data can conform to the channel propagation characteristics of the measured scenario, and the channel parameters reported by the UE are not equivalent to the original channel measurement data. Therefore, compared with the channel measurement data, the channel simulation data obtained by simulating the channel parameters reported by the UE increases the diversity of the data. Furthermore, when constructing the training data of the neural network based on the channel simulation data, the training data of the neural network can have a certain degree of randomness and generalization ability, which is conducive to improving the training accuracy of the neural network and the generalization ability of the trained neural network.

[0103] For example, when constructing training data for an AI model based on channel simulation data, the monitoring process of the AI ​​model only needs to detect whether the parameters of the channel measurement data extracted by the UE have changed significantly. There is no need to formulate cumbersome performance indicators, and the detection is more convenient. For example, when applying latent consistency models (LCMs), the parameters of the channel measurement data extracted by the UE can be used as the performance matrix for model detection.

[0104] FIG4 is an interactive flow chart for implementing channel parameter processing according to an embodiment of the present disclosure. As shown in FIG4 , the process may include:

[0105] Step 41: The base station sends configuration information to the UE.

[0106] Step 42: The UE obtains channel measurement data through channel measurement.

[0107] Here, the UE may perform channel measurement according to the channel parameters that the UE needs to report in the configuration information.

[0108] Step 43: The UE extracts parameters of the channel measurement data.

[0109] Step 44: The UE performs data analysis on the parameters of the channel measurement data to obtain channel parameters.

[0110] Step 45: The UE reports channel parameters to the base station according to the configuration information.

[0111] In summary, the technical solution of the embodiment of the present disclosure can solve the problem of high overhead of the collected channel measurement data, and can greatly reduce the air interface overhead. For example, in the related art, the channel matrix reported by the UE to the network side device is of Nt*SB (8*13) dimension, and 400,000 channel matrix data are uploaded to the base station side through the channel, which will bring huge overhead. In the embodiment of the present disclosure, only a number of channel parameters need to be transmitted. Compared with the technical solution of the related art, the amount of data that needs to be transmitted is hundreds of thousands of times different, so the embodiment of the present disclosure can greatly reduce the air interface overhead. At the same time, when the AI ​​model needs to be retrained, the air interface overhead can also be reduced.

[0112] Those skilled in the art will understand that in the above-mentioned method of the specific implementation method, the writing order of each step does not mean a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.
