[0002] Multi-antenna technology covers a variety of key methods, such as multiple input multiple output (MIMO), joint transmission (JT) and high-frequency beamforming. These technologies are widely used in various types of radio communication mobile networks because they can significantly improve the performance of wireless communication systems.

[0036] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0037] Unless otherwise required by the context, throughout the specification and claims, the term "comprise" and other forms such as the third-person singular form "comprises" and the present participle form "comprising" are interpreted as open and inclusive meanings, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" etc. are intended to indicate that the specific features, structures, materials or characteristics related to the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representations of the above terms are not necessarily referring to the same embodiment or example. In addition, the described specific features, structures, materials or characteristics can be included in any one or more embodiments or examples in any appropriate manner.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present disclosure, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0039] In the following description, suffixes such as "module", "component", or "unit" used to denote elements are only for the convenience of description of the present application and have no specific meaning per se. Therefore, "module", "component", or "unit" may be used interchangeably.

[0040] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to mean serving as an example, illustration, or explanation. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0041] In addition, the use of "based on" means open and inclusive because a process, step, calculation, or other action "based on" one or more of the stated conditions or values may, in practice, be based on additional conditions or values beyond those stated.

[0042] Multi-antenna technology is an important technology for improving spectral efficiency in the field of wireless communication. To exploit the performance of multi-antenna, accurate CSI needs to be obtained. Based on advanced information processing technologies such as artificial intelligence (AI), etc., the channel state information can be predicted, so that the channel state information at multiple future moments can be obtained. The scheduling and planning can be advanced based on the predicted channel state information, thereby obtaining better wireless communication performance. That is to say, the channel state information prediction technology can predict the channel state at one or more future moments based on the historical channel state information, helping the wireless communication system to achieve advanced scheduling and planning, and further optimizing the performance of the wireless communication system. However, the performance of the model or information processing method for channel state information prediction may fluctuate with the change of the channel environment and may sometimes no longer adapt to the current channel environment, so the performance of the model or information processing method for channel state information prediction needs to be monitored. Sometimes, it is also necessary to train or fine-tune the model or information processing method. Currently, the transmitted reference signals often cannot effectively achieve the goals such as performance monitoring or training of the model.

[0043] In view of this, the present disclosure provides a method for transmitting channel state information, the method comprising: receiving signaling information, and 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 signals on the K first reference signal resources, and determining N second channel state information according to the second reference signals on the L second reference signal resources; wherein K, L, and N are all positive integers; transmitting a channel state information report, wherein the channel state information report includes 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 performance parameters determined according to the K first channel state information and the N second channel state information. Thus, one or more information processing manners can be managed according to the acquired channel state information, such as performing effective performance monitoring, training, or fine-tuning on the information processing manners. 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 respectively determined, 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 manners, such as training, fine-tuning, and performance monitoring of the information processing manners. Thus, the accuracy of management of information processing manners such as performance monitoring is improved.

[0044] Correspondingly, the present disclosure further provides a method for transmitting signaling information, comprising: transmitting signaling information; the signaling information is used to determine K first reference signal resources and L second reference signal resources; receiving a channel state information report; wherein the channel state information report includes 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 performance parameters; K, L, and N are all positive integers. In this way, the determined N second channel state information can be used to manage one or more information processing manners, such as training, fine-tuning, and performance monitoring of the information processing manners.

[0056] In some embodiments, in order to save signaling overhead, etc., multiple reference signal resources may be divided into multiple sets (the reference signal resource set is sometimes also called the reference signal resource group, such as CSI-RS resource set, CSI-IM resource set, SRS resource set). The reference signal resource set includes at least one reference signal resource, and multiple reference signal resource sets may come from the same reference signal resource setting (such as CSI-RS resource setting, SRS resource setting, where the CSI-RS resource setting may be merged with the CSI-IM resource setting and both are called CSI-RS resource setting) to configure parameter information.

[0057] In some embodiments, a time instance represents a time period, such as a time slot, for example, a time slot (slot), a mini-slot (mini slot), or a symbol group. A time slot or a mini-slot may include at least one symbol. Here, a symbol refers to a time unit in a subframe, a frame, or a time slot, and the unit may be milliseconds, microseconds, nanoseconds, seconds, etc. For example, it may be an orthogonal frequency division multiplexing (OFDM) symbol, a single-carrier frequency division multiple access (SC-FDMA) symbol, an orthogonal frequency division multiple access (OFDMA) symbol, or symbols corresponding to various new waveforms in future communication systems. In some embodiments, the described time slot may be replaced with a time instance, a mini-slot, etc.

For example, the channel state information is carried on the uplink transmission resource for feedback or transmission. Both the uplink transmission resource and the CSI to be transmitted on the uplink transmission resource may be configured or indicated by the channel state information report. In one example, transmitting a CSI report means transmitting the content to be transmitted indicated in the CSI report, including but not limited to the channel state information. Here, transmission includes sending or receiving, and may also be replaced by feedback or receiving.

[0071] In some embodiments, the antenna is a physical antenna. In some examples, the antenna is a logical antenna.

[0079] S101. Receive signaling information, and determine K first reference signal resources and L second reference signal resources according to the signaling information.

[0080] Wherein, the signaling information is used to determine K first reference signal resources and L second reference signal resources. Exemplarily, the signaling information can be sent by the base station, and the terminal receives the signaling information and determines K first reference signal resources and L second reference signal resources according to the received signaling information.

[0081] In some embodiments, the K first reference signal resources determined according to the signaling information are transmitted in different time slots. For example, the K first reference signal resources are reference signal resources of periodic reference signal resources or semi-persistent reference signal resources in different periods, or reference signal resources of aperiodic reference signal resources in K time slots. Among them, the time slots corresponding to two adjacent first reference signal resources differ by a time slot offset or a period.

[0082] In some embodiments, the L second reference signal resources determined according to the signaling information are transmitted in different time slots. For example, the L second reference signal resources are reference signal resources of periodic reference signal resources or semi-persistent reference signal resources in different periods, or reference signal resources of aperiodic reference signal resources in L time slots. Among them, the time slots corresponding to two adjacent second reference signal resources differ by a time slot offset or a period.

In some embodiments, the time slot offset may be an integer multiple of T, where T is the period length of the periodic reference signal resource or the semi-persistent reference signal resource.

[0084] In some embodiments, the K first reference signal resources determined according to the signaling information are the reference signal resources of the aperiodic reference signal in adjacent K consecutive periods under the same configuration. The L second reference signal resources determined according to the signaling information are the reference signal resources of the aperiodic reference signal in adjacent L consecutive periods under the same configuration. Wherein, there is a time slot offset between the time slot where the last first reference signal resource among the K first reference signal resources is located and the time slot where the last second reference signal resource among the L second reference signal resources is located.

[0110] In some embodiments, the received signaling information may include parameters for determining K first reference signal resources and L second reference signal resources. Exemplarily, for a set of reference signal resources or a set of multiple sets of reference signal resources, the base station may send signaling information. The terminal receives the signaling information, where the signaling information includes parameters for indicating one or more reference signal resources. In some embodiments, the parameters of the multiple reference signal resources may include the parameters of K first reference signal resources and L second reference signal resources, so that the terminal can determine the K first reference signal resources and the L second reference signal resources according to the received signaling information.

[0111] In some embodiments, the signaling information further includes at least one of the following (that is, the parameters of the reference signal resources indicated by the signaling information and / or the parameters of the channel state information report include at least one of the following):

[0112] 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, the value of L.

[0114] In addition, the signaling information may further include other conventional parameters, such as parameters for indicating the time domain resources, frequency domain resources, code domain resources, spatial domain resources, etc. of the reference signal, which will not be described in detail here.

[0115] 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.

[0116] Wherein, 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.

[0117] In some embodiments, K first reference signals can be received respectively on K first reference signal resources. Then, based on the K first reference signals, K first channel state information is determined. And 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.

[0118] In some embodiments, one 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, partial or all channel information. One 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, partial or all channel information. Of course, in some possible examples, the first channel state information or the second channel state information can also be other channel state information parameters, and the present disclosure does not limit this.

[0119] Exemplarily, a wireless communication system may include one or more base stations and one or more terminals. Among them, each base station may include multiple antennas, and each terminal may include one or more antennas. The base station sends reference signals, the terminal receives the reference signals sent by the base station, and measures the channels to obtain channel state information, such as channel state information such as L1-RSRP, differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, partial or all channel information. In some embodiments, the channel state information obtained here can be used as the above first channel state information or second channel state information.

[0120] S103. Send a channel state information report.

[0121] Wherein, the channel state information report includes 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, performance parameters determined based on the K first channel state information and the N second channel state information.

[0122] In some embodiments, N third channel state information may be generated based on K first channel state information. Furthermore, performance parameters may be determined based on the N second channel state information and the N third channel state information.

[0123] In some embodiments, the N third channel state information may also be sent in a channel state information report.

[0124] In some embodiments, the K first reference signal resources determined according to signaling information may be on an observation window. Wherein, K may be the length of the observation window. In addition, the observation window may also have other possible names such as a measurement window. Thus, the reference signals on the K first reference signal resources may be measured to obtain K first channel state information.

[0125] Thus, in the process of channel state information prediction, the obtained K first channel state information may be used as input parameters for an information processing method for predicting channel state information, and the output of this information processing method may be N third channel state information, and the N third channel state information is the prediction result. And, L second reference signal resources are on a prediction window. Wherein, L may be the length of the prediction window. In addition, the prediction window may also have other possible names. In some examples, there may be no prediction window or it may be necessary to send reference signals on the prediction window, such as during model inference. While during model monitoring or for model training, reference signals are sent on the prediction window to obtain the label part of the sample. Thus, it is necessary to measure the reference signals on the L second reference signal resources to obtain L second channel state information, where all or part of the L second channel state information may be used as labels for an information processing method, so as to monitor the prediction performance of this information processing method, etc.

[0126] In some embodiments, the above-mentioned K first channel state information may represent the channel state information on K time slots. Each first channel state information may be a channel information, or a matrix or vector composed of one or more L1-RSRP. In other embodiments, L1-RSRP here may be replaced by differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, etc. The above-mentioned L second channel state information represents the channel state information on L time slots. Each second channel state information may be a channel information, or a matrix or vector composed of one or more L1-RSRP. In other embodiments, L1-RSRP here may be replaced by differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, etc.

[0127] It should be noted that as the environment or channel changes, the information processing method adopted, or the model corresponding to the information processing method, or the function corresponding to the information processing method may no longer be suitable for the new environment or channel after the change. Therefore, it is necessary to perform performance monitoring on the information processing method, or the model corresponding to the information processing method, or the function corresponding to the information processing method. Thus, the channel state information corresponding to K first reference signal resources and L second reference signal resources can be sent for performance monitoring. And in actual performance monitoring, multiple groups of reference signal resources may be used, and each group of reference signal resources includes the K first reference signal resources and the L second reference signal resources. In other examples, the channel state information corresponding to the K first reference signal resources and the L second reference signal resources can also be used for training or fine-tuning.

[0128] In some embodiments, N second reference signal resources corresponding to N second channel state information can also be determined from the L second reference signal resources. And N second reference signals on the N second reference signal resources are received, and N second channel state information is determined according to the N second reference signals.

[0129] Exemplarily, as Figure 3 shown, Figure 3 the reference signal resources shown in 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 1, and the offset of the second reference signal resources is 5. Among them, the first reference signal resources are located within the measurement window or the observation window, the second reference signal resources are located within the prediction window, and the reference signal for channel state information reporting measurement can be after the channel state information reference (CSI-Reference). The first reference signals on the K first reference signal resources can be received according to the time-frequency position of the reference signal resources determined by the signaling information, 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 the input of the information processing method to obtain N third channel state information (predicted channel state information) of the output. Among them, these N third channel state information can be on different time slots respectively, and the interval of the third channel state information is the fifth interval.

[0130] In some examples, for performance monitoring of this information processing method, L second reference signal resources may be received in a prediction window, and the K second reference signal resources may be measured to obtain N second channel state information. Among them, the N second channel state information are respectively on N time slots, with an interval of a fourth interval. In some embodiments, L = N, so that the time slots where the second channel state information is located and the time slots where the second reference signal resources are located are in 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 by an offset from the time slot where the i-th second reference signal resource is located, i = 1, …, N.

[0131] In one example, the i-th reference signal is transmitted on the i-th reference signal resource, and the transmission time slot may be n offset +i*m.

[0132] In one example, the time slot where the k-th third channel state information is located is n + δ + k*d. Among them, δ is the offset of the reference signal n offset , 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 may be the distance between the first third channel state information and the CSI report, or may be referred to as the fifth offset. Here, i = 1, …, K, k = 1, …, N.

[0133] In some embodiments, the third channel state information correspondence and the second reference signal resources are aligned in time slots.

[0134] It should be noted that as Figure 4 shown, 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 2, and the offset of the second reference signal resources is 5. Among them, the first reference signal resources are located in the measurement window or the observation window, and the second reference signal resources are located in the prediction window. Among them, 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 determined by the second reference signals on the second reference signal resources. As Figure 4As shown, taking the second channel state information 41 and the third channel state information 42 as examples, it can be seen that the time slots where the second channel state information 41 is located and the time slots where the third channel state information 42 is located are different, that is, there will be a situation where the predicted channel state information (the second channel state information) and the labeled channel state information (the third channel state information) are not aligned. At this time, it is impossible to use the labeled channel state information (the second channel state information) to monitor the performance of the predicted channel state information (the third channel state information) and the information processing method, or it will affect the accuracy of performance monitoring.

[0135] In some embodiments, the reference signal for channel state information reporting measurement may be before the channel state information reference (CSI-Reference), where n - 4 ≥ n offset + K × m.

[0136] In some embodiments, the terminal needs to send the capability description information in at least one time slot, and the base station receives the capability description information of the terminal. In one embodiment, the capability description information is transmitted through higher layer signaling and / or physical layer signaling. In one embodiment, the capability description information is used to describe the input information and output information of the model or the model corresponding to the 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 the input CSIs, the interval between the reference signal resources corresponding to the input CSIs, 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 the output CSIs, the interval between the reference signal resources corresponding to the output CSIs, the interval between the reference signal resources for the label, the interval between the last input CSI and the first output CSI. In other embodiments, the interval here can also be replaced by bias, the period of the reference signal resource, the period of the CSI, the period of the CSI report, etc. The subsequent content about the capability description information will not be elaborated one by one.

[0137] In some embodiments, n offset = n + δ, m = d. And, the interval or period, bias information, etc. of the reference signal resource can be determined according to the capability description information. It should be noted that in order to make the predicted channel state information (the third channel state information) and the labeled channel state information (the second channel state information) aligned in time slots, that is, the time slot corresponding to the i-th predicted channel state information is the same as the time slot corresponding to the i-th labeled channel state information, where i = 1,..., N. Thus, n offset = n + δ, m = d. And, the interval or period, bias information, etc. of the reference signal resource can be determined according to the capability description information.

[0138] Exemplarily, the above-mentioned capability description information can also be referred to as user capability description information. The capability description information may include at least one of the following: input description information, output description information. In one example, the input description information may include at least one of the following: the number K of the first channel state information, the third interval of the first channel state information, and the third offset of the first channel state information. Alternatively, the output description information may include at least one of the following: the number N of the 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, the input description information includes one of the input description information of a function, the input description information of a model, the input description information of an information processing method, etc. Alternatively, the output description information includes one of the output description information of a function, the output description information of a model, the output description information of an information processing method, etc.

[0139] In some embodiments, at least one of the following can be determined according to the capability description information: the value or value range of the first offset, the value or value range of the second offset, the value or value range of the third offset, the value or value range of the fourth offset, the value or value range of the fifth offset, the value or value range of the first time domain interval, the value or value range of the second time domain interval, the value or value range of the third time domain interval, the value or value range of the fourth time domain interval, the value or value range of the fifth time domain interval.

[0140] In some embodiments, the first offset, the third offset, and the fourth offset satisfy any one of the following:

[0141] The value of the third offset and / or the fourth offset is determined according to the first offset;

[0142] The value range of the third offset and / or the fourth offset is determined according to the first offset;

[0143] The value of the first offset is determined according to the third offset and / or the fourth offset;

[0144] The value range of the first offset is determined according to the third offset and / or the fourth offset.

[0145] In one example, the value or value range of the third offset can be determined according to the first offset. In other examples, the third offset here can also be replaced by the fourth offset or the fifth offset. That is, the value or value range of the fourth offset or the fifth offset can be determined according to the first offset.

[0146] In another example, the value or value range of the first offset can be determined according to the third offset. In other examples, the third offset here can also be replaced by the fourth offset or the fifth offset. That is, the value or value range of the first offset can be determined according to the fourth offset or the fifth offset.

[0147] In another example, the value or value range of the third interval can be determined according to the first interval. Here, the first interval can also be referred to as the first time-domain interval, and the third interval can also be referred to as the third time-domain interval. In other examples, the third interval here can also be replaced by the fourth interval or the fifth interval. That is, the value or value range of the fourth interval or the fifth interval can be determined according to the first interval. In addition, the fourth interval can also be referred to as the fourth time-domain interval, and the fifth interval can also be referred to as the fifth time-domain interval.

[0148] In another example, the value or value range of the first interval can be determined according to the third interval. In other examples, the third interval here can also be replaced by the fourth interval or the fifth interval. That is, the value or value range of the first interval can be determined according to the fourth interval or the fifth interval.

[0149] In some embodiments, at least one threshold information may also be received. Further, the second channel state information can be determined according to the received at least one threshold information. And the performance parameter can be determined according to the received at least one threshold information, N pieces of second channel state information, and N pieces of third channel state information.

[0150] In some embodiments, the threshold information is a threshold value, which can be a real number, or a positive real number, or a positive integer, a Boolean value, a string, etc. It can also be an index of a set of threshold values, and each index of the threshold value corresponds to a threshold value. Details will not be elaborated hereinafter.

[0151] In some embodiments, the at least one threshold information is determined based on at least one of the following: 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, the channel quality information, the moving speed of the terminal device, the carrier spacing, the type of input data, the number of input data streams, and the information processing method adopted.

[0152] It should be noted that the information processing method or the model of the information processing method can be determined according to the period or interval of the reference signal. Among them, 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 from the model, and the distance between the period or interval of the second reference signal and the interval of the channel state information output from the model is less than a preset threshold.

[0153] Exemplarily, the time slot corresponding to the k-th predicted channel state information (the third channel state information) may be T CSI，k = n + δ + k*d. And the time slot where the i-th reference signal resource (the second reference signal resource) in the prediction window is located may be T CSI-RS = n offset + i*m. When i = k, T CSI，k ≠ T CSI-RS , thus, the k-th predicted channel state information (the third channel state information) and the k-th labeled channel state information (the second channel state information) are misaligned. Therefore, the reference signal resource corresponding to the k-th predicted CSI can be determined, and the reference signal on the reference signal resource corresponding to the k-th predicted CSI is measured to obtain the k-th labeled CSI, so that the k-th labeled CSI and the k-th predicted CSI are aligned, k = 1,..., N.

[0154] In some embodiments, among the L second reference signal resources, determine the N second reference signal resources corresponding to the N second channel state information, receive the N second reference signals on the N second reference signal resources, and determine the N second channel state information according to the N second reference signals. Among them, the N second reference signal resources corresponding to the determined N second channel state information include one of the following:

[0155] The k-th 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 k-th reference time slot;

[0156] The k-th 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 k-th reference time slot and the time slot is less than or equal to the k-th reference time slot;

[0157] The k-th 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 k-th reference time slot and the time slot is greater than or equal to the k-th reference time slot;

[0158] The k-th second reference signal resource among the N second reference signal resources is the reference signal resource with the same time slot as the k-th reference time slot;

[0159] Among them, the k-th reference time slot is the time slot corresponding to the k-th third channel state information, or the smallest time slot in the time slot interval corresponding to the k-th third channel state information, k = 1, 2,..., N.

[0160] In one example, C reference signal resources closest to the time slot corresponding to the k-th third channel state information may be used as the reference signal resources corresponding to the k-th third CSI. That is, |T CSI，k - T CSI-RS，iMeet a preset threshold.

[0161] In another example, the first 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 Meet a preset threshold and be greater than or equal to 0.

[0162] In yet another example, the last C reference signal resources closest to the time slot corresponding to the k-th third channel state information are used as the reference signal resources corresponding to the k-th third channel state information. That is, T CSI-RS，i -T CSI，k Meet a preset threshold and be greater than or equal to 0.

[0163] Where C is a positive integer. When C is greater than 1, C channel state information can be measured, and the k-th labeled channel state information can be obtained based on the C channel state information. For example, the k-th labeled channel state information is obtained by linearly or non-linearly interpolating the C channel state information. Here, T CSI，k is the time slot where the k-th third CSI is located, and T CSI-RS，i is the time slot where the i-th second reference signal is located.

[0164] Exemplarily, the value of C can be configured for the terminal through the high-layer and / or physical-layer signaling of the base station. Or, the value of C can be determined through negotiation between the base station and the terminal, or 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 whose time slots are less than or equal to the time slot corresponding to the k-th 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 whose time slots are greater than or equal to the time slot corresponding to the k-th third channel state information.

[0165] In some embodiments, the difference between the time slot where the k-th second channel state information in the N second reference signal resources is located and the k-th reference time slot is less than a first threshold value, where k = 1, 2,..., N.

[0166] In some embodiments, the acquisition method of the N second channel state information is different from the acquisition method of the N third channel state information. Here, the acquisition method of the channel state information is also a kind of information processing method, such as the prediction method of the channel state information.

[0167] It should be noted that in some possible scenarios, there may be no second reference signal resource, or the second reference signal resource is severely interfered, and the measured second channel state information is very poor, not meeting the requirements for tagging. In this case, through traditional channel state information prediction algorithms, such as Wiener filtering, Kalman filtering and other channel state information prediction algorithms, K first channel state information can be predicted to obtain N second channel state information, or referred to as the fourth channel state information. The difference between the fourth channel state information and the third channel state information lies in the different information processing methods used. For example, the third channel state information uses artificial intelligence methods for channel state information prediction, while the fourth channel state information uses non-artificial intelligence methods for channel state information prediction.

[0168] Exemplarily, based on the N fourth channel state information H n and the N third channel state information H a the characteristic parameter m2 = f(H n , H a ) can be determined, so that based on the N second channel state information H and the N third channel state information H a the characteristic parameter m1 = f(H, H a ) can be determined. It should be noted that the accuracy of m1 may be higher than that of m2, and there is a difference between the two. Therefore, the performance monitoring threshold configured for m2 can be smaller than that of m1. Or a conversion factor can be configured to perform an operation on m2 and the conversion factor. For example, m2 is divided by the conversion factor and then compared with a preset threshold.

[0169] In one example, the base station can indicate a threshold or a conversion factor through higher layer and / or physical layer signaling, so that the terminal receives the higher layer and / or physical layer signaling to obtain the threshold or the conversion factor. Furthermore, based on the threshold or the conversion factor, the second channel state information is determined.

[0170] In one example, a threshold or a scaling factor can be determined according to a first time domain interval. For example, the larger the first time domain interval is, the smaller the threshold or the scaling factor is. In some embodiments, the first time domain interval therein can be replaced by one of a second time domain interval, a third time domain interval, a fourth time domain interval, a fifth time domain interval, a second number L of reference signal resources, a second number N of channel state information, a third number N of channel state information, a fourth number N of channel state information, the moving speed of a terminal, the number of layers of the second channel state information, the number of layers of the third channel state information, etc. That is, a threshold or a scaling factor can be determined according to one of the first time domain interval, the second time domain interval, the third time domain interval, the fourth time domain interval, the fifth time domain interval, the second number L of reference signal resources, the second number N of channel state information, the third number N of channel state information, the fourth number N of channel state information, the moving speed of the terminal, the number of layers of the second channel state information, the number of layers of the third channel state information, etc.

[0171] In one example, a threshold or a scaling factor can be determined according to the number K of first reference signal resources. For example, the larger K is, the larger the threshold or the scaling factor is. In some embodiments, the number K of the first reference signal resources here can be replaced by the number of first channel state information and the carrier spacing.

[0172] In some embodiments, the time slot information corresponding to the first third channel state information among the N third channel state information is determined according to the time slot where the Kth first reference signal resource is located and a second offset.

[0173] Exemplarily, 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.

[0174] In some embodiments, the time slot of the first predicted channel state information (third channel state information) can be determined according to the time slot n of the K first channel state information and a fourth offset. As Figure 5 shown, 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. Among them, the time slot of the first predicted channel state information (third channel state information) can be determined according to 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 here can be replaced by a second offset or a fifth offset. In another example, the Kth first channel state information here can be replaced by the Kth first reference signal resource.

[0175] In some embodiments, at least one of the following may also be satisfied:

[0176] 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;

[0177] 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;

[0178] 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;

[0179] 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.

[0180] In some embodiments, the time slot of the first second reference signal resource may be determined according to the time slot n of the Kth first channel state information and the fourth offset. In one example, the fourth offset here may be replaced by the second offset or the fifth offset. In another example, the Kth first channel state information here may be replaced by the Kth first reference signal resource.

[0181] In some embodiments, the base station may configure a cycle of reference signal resources, and the terminal receives the reference signal on the cycle of reference signal resources and measures the reference signal to obtain the first channel state information and the second channel state information. Among them, the above K first reference signal resources may correspond to K consecutive cycles on the cycle reference signal. The L second reference signal resources may correspond to L consecutive cycles on the cycle reference signal.

[0182] Among them, the cycle of the cycle reference signal is T, that is, the reference signal resources are sent every T time slots. In one example, when configuring the cycle T of the reference signal resources, 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 cycle T of the reference signal resources, T is less than or equal to the interval d of the N output channel state information of the information processing method.

[0183] In some embodiments, in some embodiments, the deactivated 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.

[0184] Exemplarily, the base station may configure a semi-persistent reference signal resource, and may activate the semi-persistent reference signal through a physical layer or a high-layer signaling, and start transmitting the reference signal resource after a time domain interval of activating the semi-persistent reference signal. Thus, the terminal may start receiving the semi-persistent reference signal only after a time domain interval after receiving the activation signaling. Moreover, the base station may use a high-layer or physical layer signaling to activate the semi-persistent reference signal. The terminal stops receiving the semi-persistent reference signal after receiving the signaling for deactivating the semi-persistent reference signal. In some embodiments, during the activation and deactivation, the base station may transmit the semi-persistent reference signal for C periods, and C may be an integer multiple greater than or equal to (K + L), that is, C≥c×(K + L). Wherein, c is a positive integer. K and L are respectively the lengths of the observation window and the prediction window, and are also positive integers. In some embodiments, the deactivation time slot t may be greater than or equal to the time slot where the L-th second reference signal is located.

[0185] In some embodiments, a channel state information report may also be sent.

[0186] In one example, the base station may jointly trigger an aperiodic reference signal and an aperiodic CSI report through a physical layer signaling Downlink Control Information (DCI). In some embodiments, the transmission time slot of the aperiodic reference signal may be n offset +i*m. The aperiodic reference signal includes K first reference signal resources, and the interval between the first reference signal resources is m, while the time slot of the predicted CSI 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 of the CSI report, which may be indicated according to the SLIV (subcarrier indication for PDSCH lowest and highest index value) field in the DCI. As Figure 6 shown, m = d = 2, and the offset delta = δ is 2. In addition, there may be no transmission of the second reference signal resources.

[0187] In some embodiments, the second reference signal resources may be transmitted. Among them, the second reference signal resources correspond to a second offset, and the reference time slot of the second offset may be the time slot of the K-th first reference signal resource. It should be noted that in some embodiments, the reference time slot of the offset of the third channel state information may also be the time slot of the K-th first reference signal resource. As Figure 7 shown, the time slot of the first second reference signal may be the time slot of the K-th first reference signal resource plus the second offset delata2 = 4.

[0188] In some embodiments, performance parameters can also be determined based on N pieces of second channel state information and N pieces of third channel state information.

[0189] In some embodiments, performance parameters can be determined based on N pieces of second channel state information, N pieces of third channel state information, and the at least one received threshold information described above. Exemplarily, N feature parameters can be determined based on N pieces of second channel state information and N pieces of third channel state information, and then performance parameters can be determined based on the N feature parameters and the at least one threshold information.

[0190] In some embodiments, N feature parameters can be determined based on N pieces of second channel state information and N pieces of third channel state information, and then performance parameters can be determined based on the N feature parameters.

[0191] Exemplarily, the terminal can calculate N feature parameters based on the obtained N pieces of second channel state information and N pieces of third channel state information. Among them, the i-th feature parameter M i can be calculated based on the i-th second channel state information H 2,i and the i-th third channel state information H 3,i , that is, M i = f(H 2,i , H 3,i ), where i = 1,..., N. f can represent a function for calculating feature parameters, such as calculating the metric of two matrices. The metric can be the correlation between two matrices, the norm or distance of two matrices, or cosine similarity, normalized least mean square error, mean square error, normalized cosine similarity, normalized squared cosine similarity, etc. In some embodiments, the feature parameters can also be discrete values. For example, when the metric of two matrices is greater than a preset threshold value (the preset threshold value can be determined based on the at least one received threshold information described above or a threshold value pre-determined by the terminal), Mi takes a first value, otherwise Mi takes a second value. The first value and the second value are two different values, such as two different boolean values, or two different integers, or two different characters or strings. Furthermore, performance parameters can be determined based on the N feature parameters.

[0192] In some embodiments, the statistical value of N feature parameters can be determined, and the statistical value can be determined as the performance parameter. In some embodiments, the statistical value of N feature parameters can be determined, and a performance evaluation result can be determined based on the statistical value of N feature parameters, and the performance evaluation result can be determined as the performance parameter.

[0193] Exemplarily, the determination of the statistical value of the N feature parameters includes any one of the following:

[0194] Determining the weighted average value of the N feature parameters as the statistical value;

[0195] Determine the geometric mean of N characteristic parameters as the statistical value;

[0203] Determine the number of parameters greater than the third threshold value among N characteristic parameters as the statistical value.

[0204] In some other embodiments, the performance parameter can be directly determined according to N characteristic parameters.

[0205] Exemplarily, determining the performance parameter according to N characteristic parameters includes any one of the following:

[0206] Determine the weighted average of N characteristic parameters as the performance parameter;

[0207] Determine the geometric mean of N characteristic parameters as the performance parameter;

[0220] Determine the performance evaluation result determined by the maximum parameter value among the N characteristic parameters as the performance parameter;

[0221] Determine the performance evaluation result determined by the minimum parameter value among the N characteristic parameters as the performance parameter;

[0222] Determine the performance evaluation result determined by the first characteristic parameter among the N characteristic parameters as the performance parameter;

[0223] Determine the performance evaluation result determined by the Nth characteristic parameter among the N characteristic parameters as the performance parameter;

[0224] Determine the performance evaluation result determined by the ratio of parameters greater than the second threshold among the N characteristic parameters as the performance parameter;

[0225] Determine the performance evaluation result determined by the number of parameters greater than the third threshold among the N characteristic parameters as the performance parameter.

[0226] In one example, determine the performance evaluation result according to a numerical value A, including, if the numerical value A is greater than a preset threshold (the preset threshold can be determined based on the at least one threshold information received above or a threshold determined in advance by the terminal), then the performance evaluation result is the first value, otherwise, the performance evaluation result is the second value. The first value and the second value are two different numerical values. For example, they are two different Boolean values, or two different integers, or two different characters or strings. Furthermore, the performance parameter can be determined according to the N characteristic parameters. The numerical value A here can be any one of the above N characteristic parameters, or their statistical values. This will not be elaborated one by one later.

[0227] In one example, N characteristic parameters M1,..., M can be determined according to N pieces of second channel state information and N pieces of third channel state information N , and then according to the N characteristic parameters M1,..., M NThe weighted average is used to determine the performance parameter.

[0228] In another example, N characteristic parameters M1, …, M can be determined according to N second channel state information and N third channel state information N , and then the performance parameter can be determined according to the geometric mean of N characteristic parameters M1, …, M N .

[0232] In yet another example, N characteristic parameters M1, …, M can be determined according to N second channel state information and N third channel state information N , and then the performance parameter can be determined according to the minimum value of N characteristic parameters M1, …, M N .

[0233] In yet another example, N characteristic parameters M1, …, M can be determined according to N second channel state information and N third channel state information N , and then the performance parameter can be determined according to the first value of N characteristic parameters M1, …, M N .

[0235] In yet another example, N characteristic parameters M1, …, M can be determined according to N second channel state information and N third channel state information N, and then determine the performance parameter according to the proportion of the N feature parameters M1, …, M N that is greater than a preset threshold, such as a second threshold value.

[0236] In another example, N feature parameters M1, …, M can be determined according to the N second channel state information and the N third channel state information. N , and then determine the performance parameter according to the number of the N feature parameters M1, …, M N that is greater than a preset threshold, such as a second threshold value.

[0237] In some embodiments, the transmitted channel state information report may include at least one of the following: a performance parameter, K first channel state information, N second channel state information, and N third channel state information.

[0238] It should be noted that the terminal can feedback the determined performance parameter through the channel state information report. The base station receives the performance parameter and determines whether the current information processing method meets the performance requirements according to the performance parameter. In one example, when the performance parameter is greater than the preset threshold value, it is considered that the current information processing method meets the performance requirements; otherwise, it is determined that the current information processing method does not meet the performance requirements. In one example, the performance parameter is a performance evaluation result. If it takes a first value, the base station considers that the current information processing method meets 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 according to the performance monitoring results of one or more times, and can instruct the terminal to perform operations such as switching or updating the information processing method when switching is required. In some embodiments, the information processing method here can be replaced by one of a model, a function, or a function, etc.

[0239] In some embodiments, the terminal can determine whether the current information processing method meets the performance requirements according to the performance parameter. For example, when the performance parameter is greater than the preset threshold value, the terminal determines that the current information processing method meets the performance requirements; otherwise, the terminal determines that the current information processing method does not meet the performance requirements. Then the terminal can feedback the result of the performance monitoring to the base station, and the base station receives the feedback of the performance monitoring result. The base station can determine whether to switch the information processing method according to the performance monitoring results of one or more times of feedback, and can instruct the terminal to perform operations such as switching or updating the information processing method when switching is required. In some embodiments, the information processing method here can be replaced by one of a model, a function, or a function, etc.

Thus, the management of information processing methods, such as the accuracy of performance monitoring, can be improved.
