[0039] Multi-antenna technology is an important technology for improving spectrum efficiency in the field of wireless communication, and to play the performance of multi-antenna, accurate CSI (Channel State Information) needs to be obtained. Based on advanced information processing technology, such as artificial intelligence (AI), etc., the channel state information can be predicted, so that the channel state information of multiple future time instants can be obtained, and the early scheduling planning can be carried out based on the predicted channel state information, so as to obtain better wireless communication performance. That is, the channel state information prediction technology can predict the channel state at one or more future time instants based on the historical channel state information, help the wireless communication system to realize the early scheduling and planning, and further optimize the performance of the wireless communication system. However, the performance of the model or information processing method used for channel state information prediction may fluctuate with the change of the channel environment, and sometimes may no longer adapt to the current channel environment, so that the performance of the model or information processing method used for channel state information prediction is monitored. Sometimes, the model or information processing method also needs to be trained or fine-tuned. The current reference signal transmission cannot effectively achieve the performance monitoring or training of the model and other goals.

[0040] Therefore, the present disclosure provides a channel state information acquisition method, which comprises: receiving signaling information, determining K first reference signal resources and L second reference signal resources according to the signaling information; determining K first channel state information according to the first reference signal on the K first reference signal resources, and determining N second channel state information according to the second reference signal on the L second reference signal resources; K, L and N are positive integers; transmitting a channel state information report, the channel state information report comprising at least one of the following: all or part of the K first channel state information, all or part of the N second channel state information, and a performance parameter determined according to the K first channel state information and the N second channel state information. Thus, one or more information processing methods can be managed according to the acquired channel state information, such as effective performance monitoring, training or fine-tuning of the information processing method, etc. Thus, K first reference signal resources and L second reference signal resources can be determined according to the received signaling information, and then K first channel state information and N second channel state information can be determined respectively, and then a channel information report is transmitted. In this way, the determined K first channel state information and N second channel state information can be used to manage one or more information processing methods, such as training, fine-tuning and performance monitoring of the information processing method, etc., so as to improve the accuracy of the management, such as performance monitoring, of the information processing method.

[0075] S101. Receive signaling information and determine K first reference signal resources and L second reference signal resources based on the signaling information.

[0076] This signaling information is used to determine K first reference signal resources and L second reference signal resources. For example, this signaling information can be sent by a base station, and the terminal receives this signaling information and determines the K first reference signal resources and L second reference signal resources based on the received signaling information.

[0077] In some embodiments, the K first reference signal resources determined according to signaling information are transmitted on different time slots. For example, the K first reference signal resources are periodic reference signal resources or semi-persistent reference signal resources on different periods, or non-periodic reference signal resources on the K time slots. The time slots corresponding to two adjacent first reference signal resources differ by one time slot offset or one period.

The time slot of the last first reference signal resource among the K first reference signal resources differs from the time slot of the last second reference signal resource among the L second reference signal resources by a time slot offset. In some embodiments, this time slot offset can be an integer multiple of T, where T is the period length of the periodic or semi-persistent reference signal resource.

[0080] In some embodiments, the K first reference signal resources determined according to signaling information are reference signal resources of an aperiodic reference signal under the same configuration over K consecutive periods. The L second reference signal resources determined according to signaling information are reference signal resources of an aperiodic reference signal under the same configuration over L consecutive periods. The time slot containing the last first reference signal resource among the K first reference signal resources differs from the time slot containing the last second reference signal resource among the L second reference signal resources by one time slot offset.

[0106] In some embodiments, the received signaling information may include parameters for determining K first reference signal resources and L second reference signal resources. For example, a base station may send signaling information for one set of reference signal resources or one set of reference signal resources from multiple sets. The terminal receives the signaling information, which includes parameters for indicating one or more reference signal resources. In some embodiments, the parameters of the multiple reference signal resources may include parameters for K first reference signal resources and L second reference signal resources, thereby allowing the terminal to determine the K first reference signal resources and L second reference signal resources based on the received signaling information.

[0107] In some embodiments, the signaling information further includes at least one of the following (i.e., the parameters of the reference signal resource indicated by the signaling information and / or the parameters of the channel state information report include at least one of the following):

[0108] The first offset of the first reference signal resource, the second offset of the second reference signal resource, the third offset of the first channel state information, the fourth offset of the second channel state information, the fifth offset of the third channel state information, the first time domain interval of the first reference signal resource, the second time domain interval of the second reference signal resource, the third time domain interval of the first channel state information, the fourth time domain interval of the second channel state information, the fifth time domain interval of the third channel state information, the value of K, the value of N, and the value of L.

In some examples, two parameters have the same value and can be combined into one parameter, and they are assumed to be the same. The first, second, third, fourth, and fifth time-domain intervals in this disclosure can also be called the first interval, second interval, third interval, fourth interval, fifth interval, or other possible names, which will not be elaborated further below.

[0110] In addition, signaling information may also include other conventional parameters, such as parameters used to indicate reference signal time domain resources, frequency domain resources, code domain resources, spatial domain resources, etc., which will not be described in detail here.

[0111] S102. Determine K first channel state information based on the first reference signals on K first reference signal resources, and determine N second channel state information based on the second reference signals on L second reference signal resources.

[0112] K, L, and N are all positive integers, and the first channel state information or the first reference signal is used to obtain the third channel state information.

[0113] In some embodiments, K first reference signals can be received on K first reference signal resources respectively. Then, K first channel state information is determined based on the K first reference signals. Similarly, N second reference signals can be received on L second reference signal resources, and then N second channel state information is determined based on the N second reference signals.

[0114] In some embodiments, the aforementioned first channel state information includes, but is not limited to, one of the following parameters: L1-RSRP, differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, and some or all channel information. The aforementioned second channel state information includes, but is not limited to, one of the following parameters: L1-RSRP, differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, and some or all channel information. Of course, in some examples, the first or second channel state information may also be other channel state information parameters, and this disclosure does not limit this.

[0115] For example, a wireless communication system may include one or more base stations and one or more terminals. Each base station may include multiple antennas, and each terminal may include one or more antennas. The base station transmits a reference signal, and the terminal receives the reference signal transmitted by the base station and measures the reference signal to obtain channel state information, such as L1-RSRP, differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, partial or complete channel information, etc. In some embodiments, the channel state information obtained here can be used as the first channel state information or the second channel state information mentioned above.

[0116] S103, Send channel status information report.

[0117] The channel state information report includes at least one of the following: all or part of K first channel state information, all or part of N second channel state information, and performance parameters determined based on the K first channel state information and the N second channel state information.

[0118] In some embodiments, N third channel state information can be generated based on K first channel state information. Then, performance parameters are determined based on the N second channel state information and the N third channel state information.

[0119] In some embodiments, N third channel state information items may also be sent in the channel state information report.

[0120] In some embodiments, the K first reference signal resources determined according to signaling information can be on an observation window. K can be the length of the observation window; furthermore, the observation window can also be named, for example, a measurement window. Thus, the reference signals on the K first reference signal resources can be measured to obtain K first channel state information.

[0121] Therefore, in the channel state information prediction process, the obtained K first channel state information can be used as input parameters for an information processing method. This information processing method is used to predict the channel state information, and its output can be N third channel state information, which are the prediction results. Furthermore, L second reference signal resources are on the prediction window. L can be the length of the prediction window; alternatively, the prediction window can have other names. In some examples, there may be no prediction window or a reference signal may need to be sent within the prediction window, such as during model inference. However, during model monitoring or training, the prediction window sends reference signals to obtain the label portion of the samples. Therefore, measuring the reference signals on the L second reference signal resources can yield L second channel state information. All or part of the L second channel state information can serve as labels for an information processing method, thereby monitoring the prediction performance of that method.

[0122] In some embodiments, the K first channel state information entries can represent channel state information in K time slots. Each first channel state information entry can be a channel information entry, or a matrix or vector composed of one or more L1-RSRP entries. In other embodiments, the L1-RSRP entry can be replaced by differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, etc. The L second channel state information entries represent channel state information in L time slots. Each second channel state information entry can be a channel information entry, or a matrix or vector composed of one or more L1-RSRP entries. In other embodiments, the L1-RSRP entry can be replaced by differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, etc.

[0123] It should be noted that, due to changes in the environment or channel, the information processing method, its corresponding model, or its corresponding function may no longer be suitable for the new environment or channel. Therefore, performance monitoring of the information processing method, its corresponding model, or its corresponding function is necessary. Thus, channel state information corresponding to K first reference signal resources and L second reference signal resources can be sent for performance monitoring. Furthermore, in actual performance monitoring, multiple sets of reference signal resources may be used, each set including the aforementioned K first reference signal resources and L second reference signal resources. In other examples, the channel state information corresponding to the aforementioned K first reference signal resources and L second reference signal resources can also be used for training or fine-tuning.

[0124] In some embodiments, N second reference signal resources corresponding to N second channel state information can be determined from the L second reference signal resources. N second reference signals on the N second reference signal resources are received, and N second channel state information is determined based on the N second reference signals.

[0125] For example, as shown in Figure 3, the reference signal resources shown in Figure 3 include at least K = 4 first reference signal resources and L = 3 second reference signal resources. The interval m = 5 for the first reference signal resources, the second interval d = 5 for the second reference signal resources, the offset delta = δ = 1, and the offset of the second reference signal resources is 5. The first reference signal resources are located within the measurement window or observation window, the second reference signal resources are located within the prediction window, and the reference signals measured in the channel state information report can be after the channel state information reference (CSI-Reference). The time-frequency position of the reference signal resources can be determined according to the signaling information, the first reference signals on the K first reference signal resources are received, and each first reference signal is measured separately to obtain K first channel state information. Furthermore, the K first channel state information can be used as input to an information processing method to obtain N third channel state information (predicted channel state information) as output. These N third channel state information can be located in different time slots, and the interval of the third channel state information is the fifth interval.

[0126] In some examples, to monitor the performance of this information processing method, L second reference signal resources can be received in the prediction window, and these K second reference signal resources can be measured to obtain N second channel state information. The N second channel state information are located in N time slots, with an interval of the fourth interval. In some embodiments, L = N, so that the time slot where the second channel state information is located and the time slot where the second reference signal resource is located are in a one-to-one correspondence, that is, the time slot where the i-th second channel state information is located is the same as or differs from the time slot where the i-th second reference signal resource is located, i = 1, ..., N.

[0127] In one example, the i-th reference signal is transmitted on the i-th reference signal resource, and the transmission time slot can be n. offset +i*m.

[0128] In one example, the time slot containing the k-th third channel state information is n+δ+k*d, where δ is the reference signal n. offset The offset is given by: m is the period of the channel state information reference signal, n is the time slot where the channel state information report is located, and d is the (time domain) interval of the third channel state information (predicted channel state information). The offset can be the distance between the first third channel state information and the CSI report, or it can be called the fifth offset. i = 1, ..., K, k = 1, ..., N.

[0129] In some embodiments, the third channel state information and the second reference signal resource are aligned in time slots.

[0130] It should be noted that, as shown in Figure 4, the reference signal resources include at least K = 4 first reference signal resources and L = 3 second reference signal resources. The interval of the first reference signal resources is m = 5, the second interval of the second reference signal resources is d = 5, the offset delta = δ is 2, and the offset of the second reference signal resources is 5. The first reference signal resources are located within the measurement window or observation window, and the second reference signal resources are located within the prediction window. Based on the K first channel state information determined by the first reference signals on the first reference signal resources and the information processing method, N third channel state information (predicted channel state information) can be obtained, and L first channel state information can be determined by the second reference signals on the second reference signal resources. As shown in Figure 4, taking the second channel state information 41 and the third channel state information 42 as examples, it can be seen that the time slot where the second channel state information 41 is located is different from the time slot where the third channel state information 42 is located, that is, there will be a situation where the predicted channel state information (second channel state information) and the tag channel state information (third channel state information) are misaligned. At this point, the label channel state information (second channel state information) cannot be used to monitor the performance of the predicted channel state information (third channel state information) and information processing method, or it may affect the accuracy of performance monitoring.

[0131] In some embodiments, the reference signal for the channel state information report measurement can be prior to the channel state information reference (CSI-Reference), n-4≥n offset +K×m.

[0132] In some embodiments, the terminal needs to transmit the capability description information in at least one time slot, and the base station receives the capability description information from the terminal. In one embodiment, the capability description information is transmitted via higher-layer signaling and / or physical-layer signaling. In one embodiment, the capability description information is used to describe the input and output information of a model corresponding to a model or information processing method. In one embodiment, the input information includes, but is not limited to, at least one of the following: the number of input CSIs, the interval between input CSIs, the interval between reference signal resources corresponding to input CSIs, and the interval between the last input CSI and the first output CSI. In one embodiment, the output information includes, but is not limited to, at least one of the following: the number of output CSIs, the interval between output CSIs, the interval between reference signal resources corresponding to output CSIs, the interval between reference signal resources used for tags, and the interval between the last input CSI and the first output CSI. In other embodiments, the interval here can also be replaced by offset, the period of reference signal resources, the period of CSIs, the period of CSI reports, etc. Further details regarding the capability description information will not be elaborated upon here.

[0133] In some embodiments, n offset =n+δ, m=d. Furthermore, the interval or period, offset information, etc., of the reference signal resources can be determined based on the capability description information. It should be noted that, in order to ensure that the predicted channel state information (third channel state information) and the tag channel state information (second channel state information) are aligned in time slots, i.e., the time slot corresponding to the i-th predicted channel state information is the same as the time slot corresponding to the i-th tag channel state information, i=1,…,N. Therefore, n offset =n+δ, m=d. Furthermore, the interval or period of the reference signal resource, offset information, etc., can be determined based on the capability description information.

[0134] For example, the aforementioned capability description information can also be referred to as user capability description information. Capability description information may include at least one of the following: input description information and output description information. In one example, input description information may include at least one of the following: the number K of first channel state information, the third interval of the first channel state information, and the third offset of the first channel state information. Alternatively, output description information may include at least one of the following: the number N of third channel state information, the fifth time-domain interval of the third channel state information, and the fifth offset of the third channel state information. In one example, input description information includes one of the following: input description information of a function, input description information of a model, input description information of an information processing method, etc. Alternatively, output description information includes one of the following: output description information of a function, output description information of a model, output description information of an information processing method, etc.

[0135] In some embodiments, at least one of the following can be determined based on the capability description information: the value or range of the first bias, the value or range of the second bias, the value or range of the third bias, the value or range of the fourth bias, the value or range of the fifth bias, the value or range of the first time domain interval, the value or range of the second time domain interval, the value or range of the third time domain interval, the value or range of the fourth time domain interval, and the value or range of the fifth time domain interval.

[0136] In some embodiments, the first bias, the third bias, and the fourth bias satisfy any one of the following:

[0137] The values ​​of the third and / or fourth biases are determined based on the first bias;

[0138] The range of values ​​for the third and / or fourth bias is determined based on the first bias;

[0139] The value of the first bias is determined based on the third and / or fourth bias;

[0140] The range of the first bias is determined based on the third and / or fourth bias.

[0141] In one example, the value or range of the third bias can be determined based on the first bias. In other examples, the third bias can also be replaced by a fourth or fifth bias. That is, the value or range of the fourth or fifth bias can be determined based on the first bias.

[0142] In another example, the value or range of the first bias can be determined based on the third bias. In other examples, the third bias can also be replaced by a fourth or fifth bias. That is, the value or range of the first bias can be determined based on the fourth or fifth bias.

[0143] In another example, the value or range of the third interval can be determined based on the first interval. The first interval can also be called the first time-domain interval, and the third interval can also be called the third time-domain interval. In other examples, the third interval can also be replaced by the fourth or fifth interval. That is, the value or range of the fourth or fifth interval can be determined based on the first interval. Furthermore, the fourth interval can also be called the fourth time-domain interval, and the fifth interval can also be called the fifth time-domain interval.

[0144] In another example, the value or range of the first interval can be determined based on the third interval. In other examples, the third interval can also be replaced by a fourth or fifth interval. That is, the value or range of the first interval can be determined based on the fourth or fifth interval.

[0145] In some embodiments, at least one threshold information may also be received. Then, second channel state information can be determined based on the received at least one threshold information. And performance parameters are determined based on the received at least one threshold information, N second channel state information, and N third channel state information.

[0146] In some embodiments, the threshold information is a threshold value, which can be a real number, a positive real number, a positive integer, a Boolean value, a string, etc. The threshold information can also be an index of a set of threshold values, where each threshold value in the set corresponds to a threshold value; this will not be elaborated further in the embodiments of this disclosure.

[0147] In some embodiments, at least one threshold information is determined based on at least one of the following: a first time-domain interval of a first reference signal resource, a second time-domain interval of a second reference signal resource, a third time-domain interval of a first channel state information, a fourth time-domain interval of a second channel state information, a fifth time-domain interval of a third channel state information, a value of K, a value of N, channel quality information, the moving speed of the terminal device, carrier spacing, the type of input data, the number of input data streams, and the information processing method used.

[0148] It should be noted that the information processing method or model of the information processing method can be determined based on the period or interval of the reference signal. The period or interval of the first reference signal can be the same as the interval of the channel state information input to the model, or the distance between the period or interval of the first reference signal and the interval of the channel state information input to the model is less than a preset threshold. And / or, the period or interval of the second reference signal is the same as the interval of the channel state information output by the model, and the distance between the period or interval of the second reference signal and the interval of the channel state information output by the model is less than a preset threshold.

[0149] For example, the time slot corresponding to the k-th predicted channel state information (the third channel state information) can be T. CSI，k = n + δ + k*d. The time slot containing the i-th reference signal resource (second reference signal resource) in the prediction window can be T. CSI-RS =n offset +i*m. When i = k, T CSI，k ≠T CSI-RS Therefore, the k-th predicted channel state information (third channel state information) and the k-th tag channel state information (second channel state information) are not aligned. Thus, the reference signal resource corresponding to the k-th predicted CSI can be determined, and the k-th tag CSI can be obtained by measuring the reference signal on the reference signal resource corresponding to the k-th predicted CSI. Therefore, the k-th tag CSI and the k-th predicted CSI are aligned, k = 1, ..., N.

[0150] In some embodiments, among L second reference signal resources, N second reference signal resources corresponding to N second channel state information are determined, N second reference signals on the N second reference signal resources are received, and N second channel state information is determined based on the N second reference signals. The N second reference signal resources corresponding to the determined N second channel state information include one of the following:

[0151] The kth second reference signal resource among the N second reference signal resources is the reference signal resource with the smallest distance between the time slot and the kth reference time slot;

[0152] The kth second reference signal resource among the N second reference signal resources is the reference signal resource whose time slot is the smallest distance from the kth reference time slot and whose time slot is less than or equal to the kth reference time slot;

[0153] The kth second reference signal resource among the N second reference signal resources is the reference signal resource whose time slot is the smallest distance from the kth reference time slot and whose time slot is greater than or equal to the kth reference time slot;

[0154] The kth second reference signal resource among the N second reference signal resources is the reference signal resource with the same time slot as the kth reference time slot;

[0155] The kth reference time slot is the time slot corresponding to the kth third channel state information, or the smallest time slot in the time slot interval corresponding to the kth third channel state information, k = 1, 2, ..., N.

[0156] In one example, the C reference signal resources closest to the time slot corresponding to the k-th third channel state information can be used as the reference signal resources corresponding to the k-th third channel state information. That is, |T CSI，k -T CSI-RS，i | Meets the preset threshold.

[0157] In another example, the top C reference signal resources closest to the time slot corresponding to the k-th third channel state information can be used as the reference signal resources corresponding to the k-th third channel state information. That is, T CSI，k -T CSI-RS , i It meets the preset threshold and is greater than or equal to 0.

[0158] In another example, the C reference signal resources closest to the time slot corresponding to the k-th third channel state information are taken as the reference signal resources corresponding to the k-th third channel state information. That is, T CSI-RS , i -T CSI，k It meets the preset threshold and is greater than or equal to 0.

[0159] C is a positive integer. When C is greater than 1, C channel state information can be measured, and the k-th tag channel state information can be obtained from these C channel state information. For example, the k-th tag channel state information can be obtained by linearly or non-linearly subtracting the C channel state information. Here, T CSI，k For the time slot where the k-th third CSI is located, T CSI-RS，i Let be the time slot where the i-th second reference signal is located.

[0160] For example, the value of C can be configured to the terminal through higher-layer signaling and / or physical-layer signaling of the base station. Alternatively, the value of C can be determined through negotiation between the base station and the terminal, or it can be a default value. In some embodiments, the value of C is less than or equal to L, where L is the number of second reference signal resources and is an integer greater than or equal to 1. In some embodiments, C is less than or equal to L and less than or equal to L1, where L1 is the number of second reference signal resources in the time slot that is less than or equal to the time slot corresponding to the kth third channel state information. In some embodiments, C is less than or equal to L and less than or equal to L2, where L2 is the number of second reference signal resources in the time slot that is greater than or equal to the time slot corresponding to the kth third channel state information.

[0161] In some embodiments, the difference between the time slot containing the kth second channel state information in the N second reference signal resources and the kth reference time slot is less than a first threshold value, k = 1, 2, ..., N.

[0162] In some embodiments, the method of acquiring N second channel state information is different from the method of acquiring N third channel state information. Here, the method of acquiring channel state information is also a kind of information processing method, such as the method of predicting channel state information.

[0163] It should be noted that in some scenarios, there may be no second reference signal resource, or the second reference signal resource may be subject to significant interference, resulting in poor measured second channel state information that does not meet the requirements for tagging. In such cases, traditional channel state information prediction algorithms, such as Wiener filtering and Kalman filtering, can be used to predict N second channel state information, or fourth channel state information, from K first channel state information. The difference between fourth and third channel state information lies in the information processing methods used. For example, third channel state information uses artificial intelligence for channel state information prediction, while fourth channel state information uses non-artificial intelligence methods.

[0164] For example, it can be based on N fourth channel state information H n and N third channel state information H a Determine the characteristic parameter m2 = f(H) n H a Based on N second channel state information H and N third channel state information H, a Determine the characteristic parameter m 1＝ f(H,H a It should be noted that the accuracy of m1 may be higher than that of m2, with a difference of one value. Therefore, the performance monitoring threshold for m2 can be configured to be smaller than that for m1. Alternatively, a conversion factor can be configured to perform calculations between m2 and the conversion factor, for example, dividing m2 by the conversion factor and then comparing it with a preset threshold.

[0165] In one example, the base station can indicate a threshold or reduction factor through higher-layer signaling and / or physical-layer signaling, thereby enabling the terminal to obtain the threshold or reduction factor by receiving the higher-layer signaling and / or physical-layer signaling. Then, the second channel state information is determined based on the threshold or reduction factor.

[0166] In one example, a threshold or reduction factor can be determined based on a first time-domain interval; for example, the larger the first time-domain interval, the smaller the threshold or reduction factor. In some embodiments, the first time-domain interval can be replaced by one of the following: a second time-domain interval, a third time-domain interval, a fourth time-domain interval, a fifth time-domain interval, the number L of second reference signal resources, the number N of second channel state information, the number N of third channel state information, the number N of fourth channel state information, the terminal's moving speed, the number of layers of second channel state information, the number of layers of third channel state information, etc. That is, the threshold or reduction factor can be determined based on one of the following: a first time-domain interval, a second time-domain interval, a third time-domain interval, a fourth time-domain interval, a fifth time-domain interval, the number L of second reference signal resources, the number N of second channel state information, the number N of third channel state information, the number N of fourth channel state information, the terminal's moving speed, the number of layers of second channel state information, the number of layers of third channel state information, etc.

[0167] In one example, a threshold or reduction factor can be determined based on the number K of the first reference signal resources; for example, the larger K is, the larger the threshold or reduction factor. In some embodiments, the number K of the first reference signal resources can be replaced by the number of first channel state information items or the carrier spacing.

[0168] In some embodiments, the time slot information corresponding to the first third channel state information among the N third channel state information is determined based on the time slot where the Kth first reference signal resource is located and the second offset.

[0169] For example, the time slot information corresponding to the third channel state information includes one of the following: the time slot corresponding to the third channel state information, the time slot interval corresponding to the third channel state information, the smallest time slot of the time slot interval corresponding to the third channel state information, the largest time slot of the time slot interval corresponding to the third channel state information, and the middle time slot of the time slot interval corresponding to the third channel state information.

[0170] In some embodiments, the time slot of the first predicted channel state information (third channel state information) can be determined based on the time slot n of K first channel state information and a fourth offset. As shown in Figure 5, the reference signal resources include at least K = 4 first reference signal resources and L = 3 second reference signal resources. The interval m of the first reference signal resources is 5, the second interval d of the second reference signal resources is 5, the offset delta = δ is 5, and the offset of the second reference signal resources is 5. The time slot of the first predicted channel state information (third channel state information) can be determined based on the fourth offset 5 of the second channel state information and the time slot n of the K first channel state information. In one example, the fourth offset can be replaced by the second offset and the fifth offset. In another example, the Kth first channel state information can be replaced by the Kth first reference signal resource.

[0171] In some embodiments, at least one of the following may also be satisfied:

[0172] The first time-domain interval of the first reference signal resource is less than or equal to the time-domain interval of the input channel state information of the first information processing method;

[0173] The first time-domain interval of the first reference signal resource is less than or equal to the time-domain interval of the output channel state information of the first information processing method;

[0174] The second time-domain interval of the second reference signal resource is less than or equal to the time-domain interval of the input channel state information of the first information processing method;

[0175] The second time-domain interval of the second reference signal resource is less than or equal to the time-domain interval of the output channel state information of the first information processing method.

[0176] In some embodiments, the time slot of the first second reference signal resource can be determined based on the time slot n of the Kth first channel state information and the fourth offset. In one example, the fourth offset can be replaced by a second offset and a fifth offset. In another example, the Kth first channel state information can be replaced by the Kth first reference signal resource.

[0177] In some embodiments, the base station may configure a reference signal resource of one period. The terminal receives and measures the reference signal on the reference signal resource of that period to obtain first channel state information and second channel state information. The aforementioned K first reference signal resources can correspond to K consecutive periods on the periodic reference signal. The L second reference signal resources can correspond to L consecutive periods on the periodic reference signal.

[0178] The periodic reference signal has a period of T, meaning the reference signal resource is transmitted once every T time slots. In one example, when configuring the period T of the reference signal resource, T is less than or equal to the input interval m of the K input channel state information of the information processing method. In another example, when configuring the period T of the reference signal resource, T is less than or equal to the interval d of the N output channel state information of the information processing method.

[0179] In some embodiments, the deactivation time slot of the second reference signal resource is greater than or equal to the time slot corresponding to the Nth third channel state information.

[0180] For example, a base station can configure a semi-persistent reference signal resource and activate the semi-persistent reference signal via physical layer or higher layer signaling, and begin transmitting the reference signal resource one time-domain interval after activating the semi-persistent reference signal. Thus, the terminal can begin receiving the semi-persistent reference signal only one time-domain interval after receiving the activation signaling. Furthermore, the base station can use higher layer or physical layer signaling to activate the semi-persistent reference signal. The terminal stops receiving the semi-persistent reference signal after receiving the deactivation signaling. In some embodiments, during the activation and deactivation period, the base station can transmit C cycles of semi-persistent reference signal, where C can be greater than or equal to an integer multiple of (K+L), i.e., C≥c×(K+L). c is a positive integer. K and L are the lengths of the observation window and prediction window, respectively, and are also positive integers. In some embodiments, the deactivation time slot t can be greater than or equal to the time slot where the Lth second reference signal is located.

[0181] In some embodiments, channel status information reports may also be sent.

[0182] In one example, the base station can jointly trigger an aperiodic reference signal and an aperiodic CSI report via a physical layer downlink control information (DCI). In some embodiments, the transmission time slot of the aperiodic reference signal can be n. offset +i*m. The aperiodic reference signal includes K first reference signal resources, with an interval of m between each of the K first reference signal resources. The predicted CSI time slot is n+δ+k*d, where δ is the time-domain offset from the DCI to the first first reference signal resource, and n is the time slot reported by the CSI, which can be indicated by the SLIV (Start and length indicator value) field in the DCI. As shown in Figure 6, m=d=2, and the offset delta=δ is 2. Furthermore, a second reference signal resource may not be transmitted.

[0183] In some embodiments, a second reference signal resource can be transmitted. The second reference signal resource corresponds to a second offset, and the reference time slot of the second offset can be the Kth first reference signal resource time slot. It should be noted that in some embodiments, the reference time slot of the offset for the third channel state information can also be the Kth first reference signal resource time slot. As shown in Figure 7, the time slot of the first second reference signal can be the Kth first reference signal resource time slot plus the second offset delta2 = 4.

[0184] In some embodiments, performance parameters can also be determined based on N second channel state information and N third channel state information.

[0185] In some embodiments, performance parameters can be determined based on N second channel state information, N third channel state information, and at least one threshold information received above. For example, N feature parameters can be determined based on the N second channel state information and the N third channel state information, and then the performance parameters can be determined based on the N feature parameters and at least one threshold information.

[0186] In some embodiments, N characteristic parameters can be determined based on N second channel state information and N third channel state information, and then performance parameters can be determined based on the N characteristic parameters.

[0187] For example, the terminal can calculate N feature parameters based on the obtained N second channel state information and N third channel state information. The i-th feature parameter M i Based on the i-th second channel state information H 2,i and the i-th third channel state information H 3,i The calculation yields, i.e., M i =f(H 2,i H 3,i ), i = 1, ..., N. f can represent a function that calculates feature parameters, such as calculating the metric of two matrices. The metric can be the correlation between the two matrices, the norm or distance between the two matrices, or cosine similarity, normalized minimum mean square error, mean square error, normalized cosine similarity, normalized square cosine similarity, etc. In some embodiments, the feature parameters can also be discrete values. For example, when the metric of the two matrices is greater than a preset threshold value (this preset threshold value can be determined based on at least one threshold information received above or a threshold value predetermined by the terminal), M i Take the first value, otherwise M i Take the second value. The first and second values ​​are two different values, such as two different Boolean values, two different integers, or two different characters or strings. Performance parameters can then be determined based on N characteristic parameters.

[0188] In some embodiments, statistical values ​​of N characteristic parameters can be determined, and these statistical values ​​can be used as performance parameters. In some embodiments, statistical values ​​of N characteristic parameters can be determined, and performance evaluation results can be determined based on these statistical values, with the performance evaluation results used as performance parameters.

[0198] The proportion of N characteristic parameters that are greater than the second threshold value is determined as the statistical value;

[0199] The number of parameters among the N feature parameters that are greater than the third threshold value is determined as the statistical value.

[0200] In some other embodiments, the performance parameters can be determined directly based on N characteristic parameters.

[0201] For example, the performance parameters are determined based on N characteristic parameters, including any one of the following:

[0221] The performance parameters are determined by the number of parameters among the N characteristic parameters that are greater than the third threshold.

[0222] In one embodiment, determining a performance evaluation result based on a numerical value A includes: if the numerical value A is greater than a preset threshold value (which can be determined based on at least one received threshold information or a threshold value predetermined by the terminal), then the performance evaluation result is a first value; otherwise, the performance evaluation result is a second value. The first value and the second value are two different numerical values. For example, they can be two different Boolean values, two different integers, or two different characters or strings. Furthermore, performance parameters can be determined based on N feature parameters. Here, the numerical value A can be any one of the aforementioned N feature parameters, or their statistical values; this embodiment will not elaborate further on these details.

[0223] In one example, N characteristic parameters M1, ..., M2 can be determined based on N second channel state information and N third channel state information. N Furthermore, based on N characteristic parameters M1, ..., M NThe performance parameters are determined by the weighted average.

[0233] In some embodiments, the transmitted channel state information report may include at least one of the following: performance parameters, K first channel state information items, N second channel state information items, and N third channel state information items.

[0234] It should be noted that the terminal can report the determined performance parameters through channel state information reports. The base station receives these performance parameters and determines whether the current information processing method meets the performance requirements based on them. In one example, if the performance parameter is greater than a preset threshold, the current information processing method is considered to meet the performance requirements; otherwise, it is determined that the current information processing method does not meet the performance requirements. In another example, the performance parameter is a performance evaluation result. If the performance parameter takes the first value, the base station considers the current information processing method to meet the performance requirements; otherwise, it is determined that the current information processing method does not meet the performance requirements. The base station can determine whether to switch the information processing method based on one or more performance monitoring results, and can instruct the terminal to switch or update the information processing method if a switch is required. In some embodiments, the information processing method here can be replaced by one of the following: a model, a function, or a feature.
