Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an information sending and receiving method, device, storage medium and program product. Background Art

[0002] Multi-antenna technology is an important means to improve data transmission rate and link reliability in wireless communication systems. It includes key technologies such as multiple input multiple output (MIMO), coordinated multipoint (CoMP) such as joint transmission (JT), and high-frequency band beamforming. To fully utilize the advantages of these technologies, the key is to obtain accurate channel state information. Through linear or nonlinear information processing techniques, such as artificial intelligence (AI) and Wiener filtering, channel state information can be predicted to know the channel status at one or more future time points in advance. This makes prediction-based scheduling possible, thereby optimizing resource allocation and enhancing the overall performance of the system.

[0003] However, as the environment and channel conditions change dynamically, the existing information processing algorithms may not be able to continuously adapt to the new environment, which may lead to a decrease in prediction accuracy, thus affecting the performance of the wireless communication system. To solve this problem, an effective performance monitoring mechanism must be implemented to track the performance of the information processing algorithm and make adjustments when necessary. Traditional performance detection methods usually rely on independent monitoring processes and dedicated reference signal transmission. Although this method can monitor the information processing algorithm, it also brings additional overhead, such as increasing the overhead of the reference signal used for monitoring, and increasing the complexity and cost of the communication system because of the need to start an independent monitoring process.

[0004] Therefore, how to reduce the reference signal transmission overhead required for performance monitoring without affecting the performance of the communication system has become one of the technical challenges that need to be solved urgently. Summary of the invention

[0085] like Figure 2 As shown, the present disclosure provides a method for sending information, the method comprising the following steps:

[0086] S101. Determine a performance parameter according to M first predicted channel state information and N second channel state information.

[0087] In some embodiments, M first predicted channel state information and N second channel state information may be acquired first, and then the performance parameter may be determined according to the M first predicted channel state information and the N second channel state information.

[0088] Among them, the first predicted 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, part or all of the channel information (such as time domain or frequency domain channel matrix, eigenvector corresponding to the time domain or frequency domain channel matrix, eigenmatrix, precoding matrix, etc.). The above-mentioned 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, part or all of the channel information. Of course, in some embodiments, the above-mentioned first predicted channel state information or the above-mentioned second channel state information may also be other possible channel state information parameters, such as CRI, RI, LI, etc.

[0089] Exemplarily, 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 sends a reference signal on at least one reference signal resource, and the terminal receives the reference signal on at least one reference signal resource, and measures the reference signal to obtain at least one of the following channel state information: such as CRI, RI, LI, broadband CQI, subband CQI, L1-RSRP, differential L1-RSRP, L1-SINR, differential L1-SINR, probability, L1-RSRQ, differential L1-RSRQ, channel information, first type of precoding information, second type of precoding information, etc. Among them, the probability can be the accurate probability of the output result of the information processing method.

[0090] In some embodiments, a periodic reference signal may be sent between communication nodes (for example, between a base station and a terminal). For example, the period of the reference signal is T, and the bias is S. The communication node transmits the above reference signal in the time slot of S+i*T. Among them, the reference signal includes but is not limited to CSI-RS, SRS, SSB, etc., i, S, T are non-negative integers, and it should be noted that i can also be a negative integer, depending on the time reference point. In some embodiments, the communication node sends a semi-continuous reference signal, that is, the period is T, the bias is S, then, the value of i is greater than or equal to 0, and less than or equal to C, where C is the total number of periods for which the reference signal is sent when the reference signal is deactivated.

[0091] In some embodiments, the second communication node is configured with a CSI report configuration, and sends the CSI report configuration to the first communication node via a signaling message. The first communication node receives the signaling message to obtain the CSI report configuration. The CSI report configuration includes but is not limited to at least one of the following: the period and offset of the CSI report, the time-frequency resources used to transmit the measurement results, the report quality reportQuantity, the time domain category reportConfigType of the report, the channel measurement resources, the interference measurement resources, the measured bandwidth size and other information. Among these CSI reports, at least two CSI reports on different transmission time slots are included. It can include the first channel status report and the second channel status report in the present disclosure.

[0092] In some embodiments, the second communication node sends the i-th CSI-RS (denoted as CSI-RS i) on the i-th CSI-RS resource, the first communication node receives the i-th CSI-RS of the i-th CSI-RS resource, and measures to obtain the i-th channel state information (CSI i), i=1,…

[0093] In some embodiments, the first communication node measures the CSI-RS of N time slots to obtain N CSIs, and uses the N CSIs to predict M CSIs of future time slots. Exemplarily, the N CSIs obtained here can be the N second channel state information mentioned above, or can also be the N first channel state information. The predicted M CSIs can be the M first predicted channel state information mentioned above, or can also be the M second predicted channel state information. For example, CSI can be used n , CSI n+1 , …, CSI n+N-1 Predict the future M predicted CSIs. The future M predicted CSIs can be recorded as p-CSI n+N , p-CSI n+1+N , …, p-CSI n+N+M-1 . Wherein, N is an integer greater than 1, and M is an integer greater than 0.

[0094] For example, the nth CSI report (denoted as CSI report n) may use CSI n , CSI n+1 , …, CSI n+N-1 Predict the future M predicted CSIs, including p-CSI n+N , p-CSI n+N+1 , …, p-CSI n+N+M-1 The n+1th CSI report (denoted as CSI report n+1) uses CSI n+C , CSI n+1+C , …, CSIn+C+N-1 Predict the future M predicted CSIs, including p-CSI n+N+C , p-CSI n+N+1+C , …, p-CSI n+N+C+M-1 . Here, C is a positive integer. The value of C can be obtained according to the transmitted high-layer and / or physical layer signaling. Or C is determined by the value agreed upon by the second communication node and the first communication node. In one embodiment, C can become the measurement resource of the nth CSI report and the offset of the measurement resource of the n+1th CSI report. Or the time slot offset of the first reference signal resource corresponding to the nth CSI report and the first reference signal resource corresponding to the n+1th CSI report.

[0095] In some embodiments, the M first predicted channel state information may be the M predicted CSI of the nth CSI report. The N second channel state information may be the N CSI for prediction of the n+1th CSI report. The nth CSI report may be the CSI report of the time slot before the n+1th CSI report. In other embodiments, in order to distinguish two different CSI reports, the two different CSI reports are referred to as the first channel state information report and the second channel state information report.

[0096] Exemplarily, the N reference signals measured by the first channel state information report may be referred to as N first reference signals, and the obtained N channel state information may be referred to as N first channel state information. The predicted M channel state information may be referred to as M first predicted channel state information. The N reference signals measured by the second channel state information report may be referred to as N second reference signals, and the obtained N channel state information may be referred to as N second channel state information. The predicted M channel state information may be referred to as M second predicted channel state information. Here, the second channel state information report and the first channel state information report are two different CSI reports, such as CSI reports on different transmission time slots. In one embodiment, they are CSI reports on different periods of the same periodic CSI report. In one embodiment, they are CSI reports on different transmission time slots in different semi-continuous CSI reports. In one embodiment, they are two different non-periodic CSI reports. In one embodiment, their transmission time slots differ by at least N1 CSI report periods, where N1 is a positive integer. They will not be described one by one in other embodiments or examples.

[0097] In some embodiments, the M first predicted channel state information are included in a first channel state information report.

[0098] Exemplarily, taking N=4 and M=1 as an example, in the nth CSI report (for example, the first channel state information report in the present disclosure), the first communication node can measure the CSI-RSn , CSI-RS n+1 , CSI-RS n+2 , CSI-RS n+3 (ie, N=4 reference signals received on the first reference signal resources), obtain CSI n , CSI n+1 , CSI n+2 , CSI n+3 (ie, N = 4 first channel state information), and based on CSI n , CSI n+1 , CSI n+2 , CSI n+3 Predict the CSI of the n+4th cycle, that is, the predicted CSI n+4 , which can be recorded as p-CSI n+4 (That is, M=1 first predicted channel state information). In the (n+1)th CSI report (for example, the second channel state information report in the present disclosure), the first communication node can measure the CSI-RS n+1 , CSI-RS n+2 , CSI-RS n+3 , CSI-RSn+4 (i.e., N=4 reference signals received on the second reference signal resources) to obtain CSI n+1 , CSI n+2 , CSI n+3 , CSI n+4 (ie, N=4 second channel state information), and based on CSI n+1 , CSI n+2 , CSI n+3 , CSI n+4 Predict the CSI of the n+5th cycle, that is, the predicted CSI n+5 , which can be recorded as p-CSI n+5 (That is, M=1 second predicted channel state information). In one embodiment, based on 1 first predicted channel state information p-CSI n+4 and 1 second channel state information CSI n+4 To calculate the performance parameters.

[0099] In some embodiments, M first predicted channel state information may be determined based on N first channel state information.

[0100] The N first channel state information are acquired based on reference signals on N first reference signal resources.

[0101] Exemplarily, the first communication node may receive reference signals on N first reference signal resources respectively, thereby acquiring the above-mentioned N first channel state information based on the received N reference signals.

[0102] Exemplarily, for the first channel state information report, the first communication node can receive N first reference signals on N different reference signal resource periods (i.e., N first reference signal resources), and measure the N first reference signals to obtain N first channel state information, and then obtain M first predicted channel state information based on the N first channel state information predictions.

[0103] In some embodiments, for the second channel state information report, the first communication node may receive N second reference signals in N different reference signal resource periods, and measure the N second reference signals to obtain N second channel state information, and then predict M second predicted channel state information based on the N second channel state information.

[0104] In some embodiments, at least one of the N first reference signal resources and the N second reference signal resources has a different transmission time slot. Alternatively, the N first reference signal resources and the N second reference signal resources are the same reference signal resource configuration with different transmission time slots.

[0105] In some embodiments, the indication information of the performance parameter may be transmitted in a second channel state information report.

[0106] In some embodiments, the content of the second channel state information report includes at least the performance parameter and all or part of the M second predicted channel state information.

[0107] M and N are both positive integers, and N is greater than or equal to M.

[0108] In some embodiments, the performance parameters may be used to measure the performance of an information processing method related to channel state information prediction. Taking the information processing method as an AI model-based method as an example, the performance of the model used to predict channel state information may obtain performance parameters of the model in terms of accuracy, efficiency, etc. when predicting channel state information. Exemplarily, the performance parameters include any of the following: correlation, cosine similarity, mean square error, squared generalized cosine similarity, normalized mean square error, etc.

[0109] In some embodiments, K first predicted channel state information may be determined based on M first predicted channel state information. K second channel state information may be determined based on N second channel state information. Performance parameters may be determined based on K first predicted channel state information and K second channel state information. K, M, and N are all positive integers, K is less than or equal to M and N, and N is greater than or equal to M.

[0110] In some embodiments, for the second CSI report, the M first predicted channel state information is the channel state information predicted in the first CSI report stored locally by the terminal. In some embodiments, the terminal retains one or more CSI report predicted channel state information for the next or several CSI reports to calculate performance parameters.

[0111] In some embodiments, the terminal will also retain one or more performance parameters of CSI reports, and the performance parameters in a CSI report can determine the final performance parameters of the current CSI report based on the performance parameters in one or more previous CSI reports and the performance parameters in the current CSI report, that is, multiple performance parameters will be filtered to obtain a more accurate performance parameter.

[0112] It should be noted that K is less than or equal to M. First, K first predicted channel state information are selected from M first predicted channel state information and K second channel state information are selected from N second channel state information. Then, based on the K first predicted channel state information and the K second channel state information, the performance parameters are determined. This can reduce the amount of data required to calculate the performance parameters and improve data processing efficiency. Channel state information can also be selected based on actual needs (that is, K first predicted channel state information and K second channel state information are selected), for example, channel state information with obvious outliers is excluded, thereby reducing the noise and interference of the outliers and improving the accuracy of performance parameters. In addition, selecting channel state information based on actual needs can also make the calculation of performance parameters more in line with the needs of actual application scenarios, so that the information processing method can better adapt to channel changes.

[0113] In some embodiments, the M first predicted channel state information are determined based on the first information processing method and the N first channel state information; and / or, the M second predicted channel state information are determined based on the first information processing method and the N second channel state information. The first information processing method includes one of the following: an artificial intelligence information processing method, a model-based information processing method, and a nonlinear information processing method. At this time, the performance parameter is used to indicate the processing performance of the first information processing method.

[0115] Among them, a subset of a set, such as a subset of set A, can be a set consisting of one or more elements of set A, or a set consisting of all elements of set A, that is, including the entire set.

[0116] In one embodiment, the p-CSI predicted by the nth CSI report may be n+N , p-CSI n+N+1 , …, p-CSI n+N+M-1 The K predicted CSIs (i.e., the K first predicted channel state information) and CSI n+C , CSI n+1+C , …, CSI n+C+N-1 The K first predicted channel state information and the K second channel state information have a corresponding relationship, which can be respectively in p-CSI j and CSI i Select K channel state information with i=j. Where j=n+N, ..., n+N+M-1, i=n+C, ..., n+C+N-1. For example, based on p-CSI n+5 and CSI n+5 to determine performance parameters.

[0117] In some embodiments, determining the K first predicted channel state information according to the N first predicted channel state information includes any one of the following:

[0130] Select the first predicted channel state information among the M first predicted channel state information.

[0131] Select the Sth first predicted channel state information among the M first predicted channel state information.

[0132] In some embodiments, the value of S may be a value directly agreed upon by the second communication node and the first communication node or a default value. Alternatively, the value of S may also be a value indicated by high-layer and / or physical-layer signaling.

[0133] In some embodiments, the first communication node may send part or all of the above-mentioned M first predicted channel state information in a first channel state information report.

[0134] In some embodiments, the time slot of the i-th second channel state information in the K second channel state information is the same as the time slot of the i-th first predicted channel state information in the K first predicted channel state information. n+5 Time slot and CSI n+5 The time slots are the same.

[0135] In some embodiments, M second channel state information may be selected from N second channel state information first, and then K second channel state information may be selected from the M second channel state information.

[0136] Exemplarily, N pieces of second channel state information may be acquired according to reference signals on N second reference signal resources.

[0137] Exemplarily, the first communication node may receive reference signals on N second reference signal resources respectively, thereby acquiring the N second channel state information based on the received N reference signals.

[0148] Exemplarily, the second time slot T2 is the same as the first time slot T1. Alternatively, the second time slot T2 is greater than the first time slot T1. For example, the second time slot T2 is the first time slot plus a time slot offset. The time slot offset may be a fixed value, or a value indicated by a high-layer signaling and / or a physical layer signaling.

[0149] In the present disclosure, bias may also be referred to as offset, offset, deviation value or other terms with the same or similar meanings, and the present disclosure does not make any specific limitations on this.

[0151] Exemplarily, the N second reference signal resources and the N first reference signal resources include at least one identical reference signal resource. For example, there may be N-1 identical reference signal resources, so that they indicate a time offset of a period T.

[0152] In some embodiments, the time slot offset between the time slot corresponding to the first first reference signal resource and the time slot corresponding to the first second reference signal resource is determined based on: the received second signaling; or a default method.

[0153] Exemplarily, there is a time slot offset D between the transmission time slot corresponding to the first first reference signal resource and the transmission time slot corresponding to the first second reference signal resource. In some embodiments, there is a time slot offset D between the transmission time slot of the first first reference signal and the transmission time slot of the first second reference signal. Wherein D is a positive integer, which may correspond to D time slots, or D reference signal cycles. In one embodiment, D is obtained according to received high-level signaling and / or physical layer signaling. In one embodiment, D is obtained according to a default or agreed value.

[0166] Exemplarily, the N second channel state information may be the N second channel state information with the largest index among the N second channel state information, such as the N-M+1th to Nth second channel state information. Exemplarily, K second channel state information may also be directly selected from the N second channel state information in a similar manner.

[0167] In some embodiments, K initial performance parameters may be determined based on K first predicted channel state information and K second channel state information, and the performance parameter may be determined based on statistical values ​​of the K initial performance parameters.

[0179] In some embodiments, the above-mentioned initial performance parameter may also belong to one of the performance parameters. For example, the performance parameter is the correlation between two channel state information. For another example, the performance parameter is the cosine similarity (CS) of two channel state information. For another example, the performance parameter is the mean square error (MSE) of two channel state information. For another example, the performance parameter is the squared generalized cosine similarity (SGCS) of two channel state information. For another example, the performance parameter is the normalized mean square error (NMSE) of two channel state information. It should be understood that the above is only an exemplary description of the performance parameters. Of course, there are other possible definitions of the performance parameters, which are not listed here one by one.

[0180] In some embodiments, the channel state information in the present disclosure may be channel information, such as a time domain channel matrix, a frequency domain channel matrix, an eigenvector or matrix corresponding to the time domain channel matrix, and an eigenvector or matrix corresponding to the frequency domain channel matrix. In some embodiments, the channel state information is first-class precoding information. In some embodiments, the channel state information is second-class precoding information. In some embodiments, the channel state information is a set of RSRP. In some embodiments, the channel state information is a set of L1-SINR. In some embodiments, the channel state information is a set of RSRQ.

[0181] In a possible implementation manner, the second channel state information report may be determined based on the above-determined performance parameter and all or part of the M second predicted channel state information.

[0182] Exemplarily, the first communication node may generate a second channel state information report based on the performance parameter and all or part of the M second predicted channel state information. That is, in the second channel state information report, it is necessary to determine the performance parameter based on the first predicted channel state information in the previous channel state information report (the first channel state information report) and the second channel state information measured in this channel state information report, and use at least one field in the second channel state information report to indicate the performance parameter, or the monitoring result of the performance parameter.

[0183] In some embodiments, the second channel state information report includes two parts, such as a first channel state information report part and a second channel state information report part, and the performance parameter is included in the first part of the second channel state information report.

[0184] It should be noted that directly including the performance parameters in the first part of the channel state information report enables the receiving end (such as the second communication node) to quickly obtain key information about the channel prediction performance, thereby improving the efficiency and accuracy of performance parameter transmission.

[0185] In some embodiments, the second channel state information report includes a first field, and the first field is used to indicate the indication information of the performance parameter. Exemplarily, the first field may be included in the first part of the second channel state information report. In one embodiment, the first field is used to indicate the performance parameter.

[0186] In some embodiments, the indication information of the performance parameter is used to indicate the monitoring result of the performance parameter or the processing result of the performance parameter. Exemplarily, the monitoring result may include that the prediction performance of the information processing method (e.g., AI model) used to predict the channel state information is poor, and the information processing method needs to be adjusted or returned. Alternatively, the monitoring result may also include that the prediction performance of the information processing method (e.g., AI model) used to predict the channel state information is good and no adjustment is required.

[0187] It should be understood that monitoring of information processing methods can also be referred to as monitoring, observation or other terms that are identical or similar in expression, and the present disclosure is not limited to this.

[0188] In some embodiments, when the performance parameter is greater than or equal to a first preset threshold, the indication information of the performance parameter takes a first value; when the performance parameter is less than the first preset threshold, the indication information of the performance parameter takes a second value.

[0189] Exemplarily, the first field is used to indicate a performance parameter, and when the performance parameter is greater than or equal to a first preset threshold, the first field takes a first value. Alternatively, when the performance parameter is less than the first preset threshold, the first field takes a second value.

[0190] Exemplarily, when the performance parameter is greater than or equal to the first preset threshold, that is, the predicted performance of the information processing method indicated by the performance parameter is good and no adjustment is required, the first field takes the first value. Alternatively, when the performance parameter is less than the first preset threshold, that is, the predicted performance of the information processing method indicated by the performance parameter is poor and the information processing method needs to be adjusted or returned, the first field takes the second value.

[0191] It should be noted that the above case where the performance parameter is equal to the first preset threshold is only an exemplary description. In some embodiments, the first field may take a second value when the performance parameter is equal to the first preset threshold, that is: when the performance parameter is greater than the first preset threshold, the first field takes the first value, or, when the performance parameter is less than or equal to the first preset threshold, the first field takes the second value.

[0192] In some embodiments, the first field may be used to carry indication information of the performance parameter, the indication information of the performance parameter is a quantized value of the performance parameter, and the first field is used to indicate the quantized value of the performance parameter.

[0193] Exemplarily, the C bit in the first field is used to indicate the quantization value of the performance parameter, and C is a positive integer. The quantization may include uniform quantization and non-uniform quantization.

[0194] Exemplarily, the first field may include 1 bit to indicate the judgment result of the performance parameter. When the performance parameter is greater than the first set threshold, the first field takes the first value, and when the performance parameter is less than the first set threshold, the first field takes the second value. The first value and the second value are two different values, such as 0 or 1, TRUE or FALSE. In another embodiment, the first field may also include multiple bits, in which case the first value and the second value are two different numbers, which may be one of an integer, a non-zero integer, a Boolean value, a character, a string, etc.

[0195] In some embodiments, when a preset condition is met, the performance parameter is a preset value; wherein the preset condition includes at least one of the following:

[0196] The amount of the first predicted channel state information is less than M;

[0197] The amount of the second predicted channel state information is less than M;

[0198] The transmission time slot of the second channel state information report is less than the first preset value;

[0199] The transmission time slot of the second channel state information report is greater than a second preset value;

[0200] The second channel state information report does not exist;

[0201] The number of received first reference signal resources is less than N.

[0202] For example, the transmission time slot of the second channel state information report is less than the first preset value, for example, the time slot where the second channel state information report is located has not received N first reference signals, and the performance parameter can take a default value or an agreed value.

[0203] For another example, the transmission time slot of the second channel state information report is greater than the second preset value, for example, the time slot where the second channel state information report is located exceeds the semi-continuous reference signal deactivation time slot, and the performance parameter takes the default value or the agreed value.

[0204] For another example, the second channel state information report does not exist, for example, there is only the first channel state information report at present, and at this time, the performance parameters in the first channel state information report take default values ​​or agreed values.

[0205] For another example, the number of first reference signal resources is less than N, and the performance parameter takes a default value or an agreed value. For example, the time slot where the second channel state information report is located has not received N first reference signals. Or, the number of second reference signal resources is less than N, and the performance parameter takes a default value or an agreed value. For example, the time slot where the first channel state information is located has not received N second reference signals.

[0206] In these embodiments, the default value or agreed value of the performance parameter may be the first value or the second value, or a quantized value of the default or agreed value.

[0207] It should be noted that in cases where there is less monitoring data or the data does not correspond (for example, the amount of the first predicted channel state information is less than M; the amount of the second predicted channel state information is less than M), or the transmission time slot interval of the channel state information report is large (for example, the transmission time slot of the second channel state information report is less than the first preset value; the transmission time slot of the second channel state information report is greater than the second preset value), the monitoring of the information processing method of the predicted channel state information may be inaccurate. At this time, the performance parameters can be directly set to preset values ​​to avoid unnecessary data processing and reduce computing resource consumption.

[0208] In some embodiments, the second channel state information report and the first channel state information report satisfy any of the following:

[0209] The transmission time slot of the first channel state information report is smaller than the transmission time slot of the second channel state information report; that is, the transmission time slot of the second channel state information report is larger than the transmission time slot of the first channel state information report;

[0210] The first channel state information report and the second channel state information report correspond to the same channel state information report configuration;

[0211] The second channel state information report includes a transmission time slot or a time slot offset for indicating the first channel state information report;

[0212] The second channel state information report includes a report identifier for indicating the first channel state information report.

[0213] The above-mentioned time slot offset can be the difference between the first second reference signal transmission time slot and the first first reference signal transmission time slot, or the offset between the starting time slot of the measurement resource corresponding to the first channel state information report and the starting time slot of the measurement resource corresponding to the second channel state information report.

[0214] Exemplarily, the collected nth sample may include N historical channel state information and M channel state information for tags, where N and M correspond to reference signals over N+M consecutive periods. For example, the nth sample is the reference signal over the i*Tth time slot, i=n, ​​n+1,…, n+N+M-1. The n+1th sample corresponds to the reference signal over the i*Tth time slot, i=n+C, n+1+C,…, n+N+M-1+C. Where C is the time slot offset, i.e., the reference signals of the two samples are offset by C periods, or C*T is the time slot offset, i.e., the reference signals of the two samples are offset by C*T time slots.

[0215] In some embodiments, one of the following may be determined according to the received first signaling or an agreed manner:

[0216] The value of K;

[0217] an offset or a number of cycles between a time slot corresponding to a first second reference signal resource and a time slot corresponding to a first first reference signal resource;

[0218] The offset or the number of cycles between the starting time slot of the measurement resource corresponding to the first channel state information report and the starting time slot of the measurement resource corresponding to the second channel state information report.

[0219] In some embodiments, the first signaling may be high layer and / or physical layer signaling.

[0220] S102: Send indication information of performance parameters.

[0221] In one example, the first communication node may send indication information of the performance parameters in the second channel state report.

[0222] In one example, the first communication node may send part or all of the M second predicted channel state information and indication information of the performance parameters in a second channel state information report.

[0223] In some embodiments, the first communication node may send a second channel state information report to the second communication node, so that the second communication node may receive the second channel state information report, determine a performance parameter in the second channel state information report, and determine whether the current information processing method meets the performance requirement based on the performance parameter.

[0224] For example, Figure 3As shown, the second communication node can send a periodic CSI-RS or a semi-persistent CSI-RS. The period is T time slots. The offset is S. The second communication node can send the i-th reference signal (CSI-RS i) in the i-th period, and the first communication node receives the i-th reference signal and measures to obtain the i-th channel state information (CSIi). Where i=n, ​​n+1,…, and n is an integer.

[0225] For the nth channel state information report (CSI report n), CSIn, CSI n+1, CSI n+2, CSI n+3 can be obtained by measuring CSI-RS n, CSI-RSn+1, CSI-RSn+2, CSI-RSn+3, and CSI n, CSI n+1, CSIn+2, CSI n+3 can be used to predict the CSI of the n+4th period (i.e., the predicted CSI n+4, for example Figure 3 For the n+1th channel state information report (CSI report n+1), CSI n+1, CSI n+2, CSI n+3, CSI n+4 can be obtained by measuring CSI-RS n+1, CSI-RS n+2, CSI-RSn+3, CSI-RS n+4, and CSI n+1, CSI n+2, CSI n+3, CSI n+4 can be used to predict the CSI of the n+5th period (i.e., the predicted CSI n+5, for example Figure 3 In CSIreport n+1, the first communication node also needs to calculate the predicted channel state information p-CSI n+4 obtained in the previous CSI report and the performance parameters of the measured CSI n+4, and feed back the calculated performance parameters. Among them, CSI report n can be the first channel state information report in the present disclosure, and CSI report n+1 can be the second channel state information report in the present disclosure.

[0226] Based on the technical solution provided by the present disclosure, the performance of the information processing method (or its corresponding model) used to predict the channel state information can be determined based on the channel state information actually measured in the current channel state information report in different time slots and the channel state information predicted in the previous channel state information report, and the indication information of the performance parameter can be generated and sent. In this way, the performance parameters can be determined based on the channel state information actually measured in the current channel state information report, without the need to start a separate monitoring process and send a reference signal of the prediction window to monitor the performance of the information processing method, thereby reducing the transmission overhead of the reference signal used for performance monitoring, or reducing the delay of the information processing method monitoring, so that the communication node can adjust the information processing method in a timely manner based on the performance parameters, and improve the accuracy of the channel state information prediction.
