[0122] Related technologies measure CSI at historical times and use CSI prediction models to predict future CSI. This reduces terminal channel measurement overhead while also improving downlink transmission spectrum efficiency and throughput. However, as a data-driven model, its CSI prediction performance deteriorates when configuration parameters are inconsistent or when the model's usage scenario changes. The predicted CSI may mislead base station scheduling decisions.

[0123] Based on this, in each embodiment of the present disclosure, the terminal reports at least one performance monitoring quantity about the CSI prediction of the terminal based on at least two CSI-RS resources. Based on the above scheme, the base station or the terminal can perform performance monitoring on the CSI prediction, thereby ensuring the prediction accuracy of the CSI prediction and, to a certain extent, guaranteeing the normal scheduling of the base station.

[0124] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments.

[0125] An embodiment of the present disclosure provides an information acquisition method, which is applied to a terminal. Referring to FIG. 1 , the method includes step 101 .

[0126] Step 101: Report at least one performance monitoring quantity related to the CSI prediction of the terminal based on at least two CSI-RS resources.

[0127] Here, the terminal reports the at least one performance monitoring metric to the network side, such as the base station. The performance monitoring metric is used to evaluate the prediction performance of the terminal when performing CSI prediction.

[0128] In one embodiment, the at least two CSI-RS resources may refer to CSI-RS resources received by the terminal at a historical moment. For example, the base station configures or indicates CSI-RS resources to the terminal through radio resource control (RRC) signaling or downlink control information (DCI), or multiple transmission opportunities of the same CSI-RS resource. In one embodiment, the at least two CSI-RS resources may refer to at least one CSI-RS resource used for terminal measurement or prediction, and at least one CSI-RS resource used for terminal performance monitoring. The two CSI-RS resources may be the same or different CSI-RS resources.

[0129] In one embodiment, reporting at least one performance monitoring metric regarding the CSI predicted by the terminal based on at least two CSI-RS resources includes:

[0130] Based on at least two CSI-RS resources, a set of performance monitoring quantities corresponding to each of T moments in time regarding the CSI predicted by the terminal is reported; wherein T is an integer greater than or equal to 1.

[0131] Specifically, before the terminal reports the performance monitoring amount set, the method further includes:

[0132] A performance monitoring quantity set corresponding to each of the T moments is obtained by calculation based on the first CSI and the second CSI corresponding to each of the T moments.

[0133] The first CSI is predicted by the terminal; the second CSI is measured by the terminal; the performance monitoring quantity set includes the at least one performance monitoring quantity; and the at least one performance monitoring quantity is used to describe the relative relationship between the first CSI and the second CSI at a corresponding moment.

[0134] In conjunction with the example in Figure 2, resource set #1 includes at least one CSI-RS resource. The terminal uses the CSI prediction model to predict the CSI-RS resource in resource set #1, obtaining N CSI#1s for the next N time moments. Resource set #2 includes at least one CSI-RS resource. The terminal measures the CSI-RS resource in resource set #2, obtaining M CSI#2s for the M transmission time moments corresponding to the at least one CSI-RS resource. In actual applications, CSI#1 and CSI#2 are of the same type. For example, both CSI#1 and CSI#2 are precoding matrix indicators (PMIs), or both CSI#1 and CSI#2 are channel matrices. Among them, T CSI#1s among N CSI#1s and T CSI#2s among M CSI#2s correspond to the same moment. That is, among these T moments, each moment corresponds to one CSI#1 (i.e., the first CSI) and one CSI#2 (i.e., the second CSI). The terminal calculates the performance monitoring quantity set of the CSI prediction model at each of the T moments based on the CSI#1 and CSI#2 corresponding to each of these T moments.

[0135] It can be understood that the above T moments are T moments among the future N moments, and are also T moments among the above M moments. If N is equal to M, then the N CSI#1s and the M CSI#2s correspond one-to-one at time, and the terminal calculates N performance monitoring quantity sets based on a pair of CSIs at each time (i.e., CSI#1 and CSI#2 at each time), that is, M performance monitoring quantity sets. If N is less than M, then the N CSI#1s and N CSI#2s among the M CSI#2s correspond one-to-one at time, and the terminal calculates N performance monitoring quantity sets based on a pair of CSIs at each of the N time moments. In this case, T is equal to N and T is less than M, and these N time moments can be the first N time moments, the last N time moments, or the middle N time moments. If N is greater than M, then the M CSI#1s and M CSI#2s among the N CSI#1s correspond one-to-one at time, and the terminal calculates M performance monitoring quantity sets based on a pair of CSIs at each of the M time moments. In this case, T is equal to M and T is less than N, and these M time moments can be the first M time moments, the last M time moments, or the middle M time moments.

[0136] Here, the performance monitoring quantity in the performance monitoring quantity set at each time moment is used to describe the relative relationship between the first CSI and the second CSI at that time moment. In one embodiment, the performance monitoring quantity is characterized by at least one of the following of the first CSI and the second CSI at the corresponding time moment:

[0137] Normalized cosine similarity;

[0138] The square of normalized cosine similarity;

[0139] Normalized mean square error.

[0140] In actual application, each performance monitoring quantity set includes one or more of the above performance monitoring quantities.

[0141] In one embodiment, each performance monitoring quantity in each performance monitoring quantity set corresponds to H subbands; H is an integer greater than or equal to 1.

[0142] Specifically, each performance monitoring quantity set includes K performance monitoring quantities, and each performance monitoring quantity corresponds to H subbands.

[0143] In one embodiment, the performance monitoring variable is calculated based on a first channel eigenvector and a second channel eigenvector of a same sub-band.

[0144] The first channel eigenvector is determined based on the first CSI at the corresponding moment; and the second channel eigenvector is determined based on the second CSI at the corresponding moment.

[0145] Specifically, corresponding to the case where the performance monitoring quantity is normalized cosine similarity:

[0146] If each performance monitoring quantity corresponds to a moment, then the normalized cosine similarity ρ can be calculated as follows:

[0147] in, Characterize the channel feature vector of the nth subband predicted by the terminal, Characterize the channel eigenvector of the nth subband measured by the terminal, there are A sub-band.

[0148] If each performance monitoring quantity corresponds to a subband at a time, then the normalized cosine similarity ρ can be calculated as follows:

[0149] in, Characterize the channel feature vector of the nth subband predicted by the terminal, Characterize the channel eigenvector of the nth subband measured by the terminal,

[0150] Corresponding to the case where the performance monitoring amount is the square of the normalized cosine similarity, the performance monitoring amount is ρ 2 :

[0151] This corresponds to the case where the performance monitoring quantity is the normalized mean square error:

[0152] If each performance monitoring quantity corresponds to a moment, then the normalized mean square error (NMSE) can be calculated as follows:

[0153] in, Characterize the channel feature vector of the nth subband predicted by the terminal, Characterize the channel eigenvector of the nth subband measured by the terminal, there are A sub-band.

[0154] If each performance monitoring quantity corresponds to H subbands at a time, then the normalized mean square error can be calculated as follows:

[0155] in, Characterize the channel feature vector of the nth subband predicted by the terminal, The channel eigenvector representing the nth subband measured by the terminal, where there are H subbands in total.

[0156] In actual application, after the terminal predicts the CSI at a certain moment in the future through the CSI prediction model, the base station sends a reference signal at that moment, and the terminal measures the reference signal at that moment to obtain the CSI actually measured at that moment, and compares it with the CSI at that moment predicted previously, thereby obtaining the performance monitoring amount of the CSI prediction model. By combining historical experience or pre-configured thresholds, the prediction performance of the CSI prediction model is evaluated based on the performance monitoring amount, thereby completing the lifecycle management of the CSI prediction model, including activating, deactivating, switching, and falling back on the CSI prediction model. However, considering that the feedback overhead of the performance monitoring amount is too large and may affect the communication efficiency, in the embodiment of the present disclosure, a solution for quantifying the performance monitoring amount is adopted to further reduce the feedback overhead of the performance monitoring amount.

[0157] Based on this, in one embodiment, the reporting of the performance monitoring quantity set corresponding to each of the T moments regarding the CSI predicted by the terminal includes:

[0158] quantifying a set of performance monitoring quantities corresponding to each of the T moments to obtain first information; and

[0159] Report the first information.

[0160] In one embodiment, quantifying the set of performance monitoring quantities corresponding to each of the T moments includes:

[0161] Each performance monitoring quantity in the performance monitoring quantity set corresponding to each of the T moments is quantized into bit information of a set number of bits.

[0162] Here, each performance monitoring quantity in the performance monitoring quantity set corresponding to each of the T moments is quantized using A bits.

[0163] Alternatively, quantifying the set of performance monitoring quantities corresponding to each of the T moments includes:

[0164] Differential quantization is performed on the performance monitoring quantity set corresponding to each of the T moments.

[0165] Differential quantization specifically involves quantizing a specified performance monitoring metric with A bits and quantizing each remaining performance monitoring metric with B bits. The B-bit quantization value represents the difference between the corresponding performance monitoring metric and the specified performance monitoring metric. Compared to quantizing each performance monitoring metric with A bits, differential quantization can further reduce the feedback overhead of performance monitoring metrics.

[0166] In one embodiment, performing differential quantization on the set of performance monitoring quantities corresponding to each of the T moments includes:

[0167] When each performance monitoring quantity set includes one performance monitoring quantity, the first performance monitoring quantity is quantized into a first set number of bit information, and the difference between the second performance monitoring quantity and the first performance monitoring quantity is quantized into a second set number of bit information.

[0168] Among them, the first performance monitoring quantity represents the performance monitoring quantity corresponding to the set moment among the T moments or the performance monitoring quantity with the corresponding maximum or minimum value; the second performance monitoring quantity represents the performance monitoring quantity other than the first performance monitoring quantity.

[0169] In actual application, the specified performance monitoring amount may be the performance monitoring amount with the largest or smallest value among all performance monitoring amounts, or the performance monitoring amount corresponding to the first moment or the last moment or other set moments.

[0170] In one embodiment, the first performance monitoring quantity represents a performance monitoring quantity with a maximum or minimum value, and the first information further includes:

[0171] The index of the time corresponding to each first performance monitoring quantity.
