A base station needs to transmit channel state information reference signals (Channel State Information Reference Signals, CSI-RSs) or synchronization signal blocks (SSBs) on all transmit beams (Tx beams), resulting in large reference signal resource consumption. At the same time, a terminal needs to measure the CSI-RSs or SSBs transmitted on all Tx beams using all receive beams (Rx beams), resulting in large measurement overhead. In order to solve these problems, artificial intelligence (Artificial Intelligence, AI) or machine learning (Machine Learning, ML) technology is introduced. The optimal beam (pair) is obtained by predicting or inferring based on measurement results of partial beams (pairs) or measurement results of historical beams (pairs), so as to save reference signal transmission resources, save terminal measurement overhead, and reduce terminal measurement time delay. However, there is no clear solution on how to report the measurement results and prediction or inference results.SUMMARY[4] The present disclosure provides a beam information reporting method, a configuration method, a device, an apparatus, and a storage medium for solving the problem of how to report measurement results and prediction or inference results.[5] In a first aspect, the present disclosure provides a beam information reporting method, which is applied to a terminal, and includes:receiving configuration information of a channel state information CSI report transmitted by a network device, where the CSI report includes a first CSI report, a second CSI report, or a third CSI report; where the first CSI report is used for reporting of a prediction result, the second CSI report is used for reporting of a measurement result, the third CSI report is used for reporting of a measurement result and a prediction result;reporting a measurement result and / or a prediction result based on the configuration information of the CSI report.[6] In some embodiments, reporting content of the first CSI report includes reference signal index information, and the reference signal index information is used for reporting predicted optimal reference signal indices of N time instances, where N is an integer greater than or equal to 1.[7] In some embodiments, the reference signal index information includes any of the following:predicted optimal K reference signal indices of each of the N time instances;predicted optimal K reference signal indices of each of a part of the N time instances, and information of a time instance whose predicted optimal K reference signal indices are repeated;predicted optimal K reference signal indices of a reference time instance of the N time instances, and offset information of predicted optimal K reference signal indices of each of other time instances relative to the predicted optimal K reference signal indices of the reference time instance, where the other time instances include all of the N time instances except the reference time instance;where K is an integer greater than or equal to 1.[8] In some embodiments, the reporting content of the first CSI report further includes predicted signal quality of reference signals corresponding to the predicted optimal reference signal indices of the N time instances.[9] In some embodiments, configuration parameters of the second CSI report include one or more of the following:a minimum reporting interval; a period of a reporting window; a number of reporting times within a reporting window; a time length of a reporting window.

[69] The term “and / or” in the embodiments of the present disclosure describes an association relationship of associated objects, and indicates that there may be three kinds of relationships. For example, A and / or B, may indicate three situations that A exists alone, A and B exists simultaneously, and B exists alone. The character “ / ” generally indicates that the associated objects before and after the character are in an “or” relationship.

[70] The term “a plurality of” in the embodiments of the present disclosure refers to two or more than two, and other quantifiers are similar.

[71] The terms “first”, “second”, and the like in the embodiments of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms thus used are interchangeable under appropriate circumstances so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and that the objects distinguished by “first” and “second” are generally of the same class, while the number of objects is not limited, for example, there may be one first object or a plurality of first objects.

[72] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present disclosure.

[73] In order to more clearly understand the technical solutions of the embodiments of the present disclosure, first, some technical contents related to the embodiments of the present disclosure are introduced.

[74] In an NR system, in order to combat the path loss in high frequency scenarios, a transmitting end and a receiving end obtain a matching beam pair through beam management, so as to improve the beamforming gain. In a downlink beam management process in the related art, a base station needs to circularly transmit Tx beams in different directions. A terminal receives the Tx beams using Rx beams, measures CSI-RS or SSB signals transmitted on all Tx beams, selects K beams (e.g., K =1, 2, 4) with the best reception performance (e.g., Layer 1-reference signal received power (Layer 1-Reference Signal Received Power, L1-RSRP)), and reports reference signal index information corresponding to these K beams to the base station. The base station selects an appropriate Tx beam for subsequent communication based on the information reported by the terminal, and indicates information of the selected beam to the terminal.

[75] In order to obtain the optimal beam pair, the base station needs to transmit CSI-RSs or SSBs on all Tx beams, resulting in large reference signal resource consumption. At the same time, the terminal needs to measure the CSI-RSs or SSBs transmitted on all Tx Beams using all Rx Beams, resulting in large measurement overhead. In order to solve these problems, AI / ML technology is introduced. The optimal beam (pair) is obtained by predicting based on measurement results of partial beams (pairs) or measurement results of historical beams (pairs), so as to save reference signal transmission resources, save terminal measurement overhead, and reduce terminal measurement delay.

[76] Two sub-use cases of AI beam management in the related art are described below.

[77] BM-case1 (beam management sub-use case 1): Spatial-domain beam prediction, that is, predicting optimal K (Top-K) beams in a beam set A (SetA) based on a beam set B (SetB) measured at a certain time instance.

[78] BM-case2 (beam management sub-use case 2): Time-domain beam prediction, that is, predicting optimal K (Top-K) beams in a beam set SetA for future M time instances based on a beam set SetB measured at L historical time instances.

[79] In the sub-use case of time-domain beam prediction, namely, BM-case2, the relationship between SetB and SetA includes the following situations:

[80] (1) SetA = SetB.

[81] (2) SetB is a subset of SetA.

[82] (3) SetB is a wide beam and SetA is a narrow beam.

[83] For time-domain beam prediction, there are two prediction modes as follows.

[84] First prediction mode: The period of the measurement time instance in a measurement window is the same as the period of the prediction time instance in a prediction window. FIG. 1 is an example diagram of a first prediction mode provided in the related art. As shown in FIG. 1, the input of an AI / ML model is the measurement values of SetB beams at four time instances, and the measurement period is X ms. The output of the AI / ML model is the optimal K beams of SetA beams for two future time instances, and the interval between the two prediction time instances is also X ms.

[85] Second prediction mode: The period of the measurement time instance is greater than the period of the prediction time instance. FIG. 2 is an example diagram of a second prediction mode provided in the related art. As shown in FIG. 2, the optimal K beams of SetA of time instances T5 and T6 are predicted from the measured SetB beams of time instances T1 and T4, and the optimal K beams of SetA of time instances T8 and T9 are predicted from the measured SetB beams of time instances T4 and T7. The period of the measurement time instance is X ms, and the interval between the two prediction time instances is Y ms, where X is greater than Y.

[86] Consider a situation where SetB = SetA, and the AI / ML model is deployed on the terminal side. In the first prediction mode of FIG. 1, the Top-K beams of SetA of time instance T1 / T2 / T3 / T4 / T7 / T8 / T9 / T10 can be obtained according to L1-RSRP of SetA measured by the terminal, and the Top-K beams of time instance T5 / T6 / T11 / T12 are obtained by prediction with the AI / ML model. The Top-K beams of time instance T1 / T4 / T7 / T10 in FIG. 2 are obtained by L1-RSRP of SetA measured by the terminal, and the Top-K beams of other time instances are obtained by prediction with the AI / ML model. The terminal needs to report the Top-K beam related information obtained by measurement or prediction to the base station, so that the base station selects the optimal beam for downlink transmitting.

[87] In the related art, the beam information reporting is based on a CSI reporting (CSI reporting) framework. Each CSI report (CSI report) is associated with one measurement resource set (when multi-TRP transmission (Multi-TRP) is not considered), and the terminal reports the indices of the optimal K reference signals in the measurement resource set and the corresponding L1-RSRP or Layer 1-signal to interference and noise ratio (Layer 1-Signal to Interference and Noise Ratio, L1-SINR). CSI reporting can adopt periodic, semi-persistent, or aperiodic reporting. Among them, the measurement reference signal associated with periodic reporting is a periodic reference signal, the measurement reference signal associated with semi-persistent reporting is a periodic reference signal or a semi-persistent reference signal, and the measurement reference signal associated with aperiodic reporting is a periodic reference signal or a semi-persistent reference signal or an aperiodic reference signal. The result reported by the terminal is a result (instantaneous result) of the last measurement before the CSI reference resource (CSI reference resource) or a result (average result) obtained after filtering the results of a plurality of measurements before the CSI reference resource, and whether to filter or not depends on the configuration of the base station side.

[88] FIG. 3 is a schematic flowchart of a beam information reporting method provided by an embodiment of the present disclosure. The method is applied to a terminal, and as shown in FIG. 3, the method includes the following steps.

[89] Step 300: receiving configuration information of a channel state information CSI report transmitted by a network device, where the CSI report includes a first CSI report, a second CSI report, or a third CSI report; where the first CSI report is used for reporting of a prediction result, the second CSI report is used for reporting of a measurement result, the third CSI report is used for reporting of a measurement result and a prediction result.

[90] Step 301: reporting a measurement result and / or a prediction result based on the configuration information of the CSI report.

[91] Specifically, the beam information reporting in the present disclosure is based on a channel state information reporting (CSI reporting) framework, and the network device (for example, a base station) configures the CSI report to be used for reporting a measurement result and / or a prediction result, where the CSI report includes a first CSI report for reporting of a prediction result, a second CSI report for reporting of a measurement result, or a third CSI report for reporting of a measurement result and a prediction result.

[92] It should be noted that in the present disclosure, “prediction” may be replaced with terms having similar meanings such as “inference” and “reasoning”. For example, “prediction result” may be replaced with “inference result” or “reasoning result”.

[93] In some implementations, the network device may configure different CSI reports for reporting the measurement result and the prediction result, respectively. For example, the first CSI report is configured for reporting of the prediction result, and the second CSI report is configured for reporting of the measurement result.

[94] In some implementations, the network device may configure the third CSI report for reporting the measurement result and the prediction result, that is, both the measurement result and the prediction result may be reported through the third CSI report.

[95] In some embodiments, the CSI report is associated with one or more reference signal resource sets. The one or more reference signal resource sets may be used for measurement and / or reporting. Among them, the reference signal resource set being used for measurement means that what is measured during the measurement are reference signals in the reference signal resource set. The reference signal resource set being used for reporting means that what is reported during the reporting is relevant information of reference signals in the reference signal resource set, such as index information of the optimal K reference signals in the reference signal resource set, signal quality information of the reference signals in the reference signal resource set, and the like.

[96] For example, the first CSI report is associated with one reference signal resource set, and the one reference signal resource set is used for both measurement and reporting. Alternatively, the first CSI report is associated with a plurality of reference signal resource sets, and the plurality of reference signal resource sets include a reference signal resource set for measurement and a reference signal resource set for reporting.

[97] For example, the second CSI report is associated with one reference signal resource set, and the one reference signal resource set is used for both measurement and reporting. Alternatively, the second CSI report is associated with a plurality of reference signal resource sets, and the plurality of reference signal resource sets include a reference signal resource set for measurement and a reference signal resource set for reporting.

[98] For example, the third CSI report is associated with one reference signal resource set, and the one reference signal resource set is used for both measurement and reporting. Alternatively, the third CSI report is associated with a plurality of reference signal resource sets, and the plurality of reference signal resource sets include a reference signal resource set for measurement and a reference signal resource set for reporting.

[99] In the present disclosure, the measurement result is information related to the optimal beams (pairs) obtained by the terminal through measuring reference signals, such as optimal K (Top-K) reference signal indices corresponding to the optimal beams, signal quality of reference signals corresponding to the Top-K reference signal indices, and other information. The prediction result is information related to the optimal beams (pairs) obtained by the terminal through performing beam prediction based on an AI / ML model (or AI / ML function, AI / ML engine, or the like), such as the optimal K (Top-K) reference signal indices corresponding to the optimal beams, the signal quality of the reference signals corresponding to the Top-K reference signal indices, and other information. The value of K may be configured by the network side, and K is an integer greater than or equal to 1.

[100] In some implementations, the signal quality includes L1-RSRP or L1-SINR, etc.

[101] By configuring the first CSI report, the second CSI report or the third CSI report to report the measurement result and / or the prediction result, the beam information reporting method provided in the embodiments of the present disclosure facilitates the use of AI / ML technology to save reference signal transmission resources, save terminal measurement overhead, and reduce terminal measurement delay, and can also adapt to the reporting requirements of different beam prediction modes, thereby improving the flexibility of beam management.

[102] In some embodiments, the reporting content of the first CSI report includes reference signal index information, and the reference signal index information is used for reporting predicted optimal reference signal indices of N time instances, where N is an integer greater than or equal to 1.

[103] For example, periodic reporting (the reporting period is configured) is used for the first CSI report. The terminal reports the predicted Top-K reference signal index information of N time instances in each time of reporting, and N is less than or equal to the number of prediction time instances output by the AI / ML model.

[104] It should be noted that, in the present disclosure, “time instance” may represent a specific point in time or a period of time, and may be replaced with terms having similar meanings such as “time”, “moment”, and “slot interval(s)”.

[105] In some embodiments, the reporting content of the first CSI report further includes predicted signal quality of reference signals corresponding to the predicted optimal reference signal indices of the N time instances (e.g., predicted L1-RSRP, L1-SINR, etc.).

[106] In some embodiments, a prediction result of one time instance reported by the terminal may be a prediction result of one time instance obtained by performing prediction according to reference signals associated with this CSI report and measured before the CSI reference resource, or a result obtained based on prediction results of a plurality of time instances (for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances).

[107] In some embodiments, the reference signal index information includes any of the following.

[108] (1) Predicted optimal K reference signal indices of each of the N time instances.

[109] For example, as shown in FIG. 1, after measuring the reference signals of time instance T4, the terminal predicts the Top-K reference signals for time instances T5 and T6 according to the AI / ML model, and reports the Top-K reference signal indices of time instance T5 and the Top-K reference signal indices of time instance T6 by the first CSI report; after measuring the reference signals of time instance T10, the terminal predicts the Top-K reference signals for time instances T11 and T12 according to the AI / ML model, and reports the Top-K reference signal indices of time instance T11 and the Top-K reference signal indices of time instance T12 by the first CSI report.

[110] (2) Predicted optimal K reference signal indices of each of a part of the N time instances, and information of a time instance whose predicted optimal K reference signal indices are repeated. In this way, the reporting overhead can be reduced.

[111] In some implementations, the terminal may report prediction results of a part of the N time instances, where the Top-K reference signal indices of this part of the N time instances are not repeated. The terminal does not repeatedly report prediction results of other time instances, but indicates to the network device which time instances have the same Top-K reference signal indices (that is, there are repetitions).

[112] In some implementations, if the Top-K reference signal indices predicted by the terminal for a certain time instance are the same as the Top-K reference signal indices predicted for the previous time instance, the terminal may not perform repeated reporting, and indicate to the network device which time instances have the same Top-K reference signal indices.

[113] For example, as shown in FIG. 1, after measuring the reference signals of time instance T4, the terminal predicts the Top-K reference signals for time instances T5 and T6 according to the AI / ML model, and if the Top-K reference signals predicted for time instances T5 and T6 are the same, the Top-K reference signal indices of time instance T5 and indication information [0 1] is reported by the first CSI report, where the second bit takes “1” to represent that the Top-K reference signal indices of the second time instance is the same as the Top-K reference signal indices of the first time instance. Here, reporting “information of the time instance whose predicted optimal K reference signal indices are repeated” by the indication information [0 1] is merely an example, and the specific form of reporting “information of the time instance whose predicted optimal K reference signal indices are repeated” is not limited in the present disclosure.

[114] (3) Predicted optimal K reference signal indices of a reference time instance of the N time instances, and offset information of predicted optimal K reference signal indices of each of other time instances relative to the predicted optimal K reference signal indices of the reference time instance, where the other time instances include all of the N time instances except the reference time instance. In this way, the reporting overhead can be reduced.

[115] In some embodiments, the reference time instance may be the first time instance of the N time instances. The terminal reports the predicted Top-K reference signal indices of the reference time instance, and indicates the predicted Top-K reference signal indices for other time instances by offset information.

[116] For example, as shown in FIG. 1, after measuring the reference signals of time instance T4, the terminal predicts the Top-2 reference signals for time instances T5 and T6 according to the AI / ML model. The terminal reports the Top-2 reference signal indices [CRI-1, CRI-2] of time instance T5 as well as offset values [offset value 1, offset value 2] of the Top-2 reference signal indices of time instanceT6 relative to the Top-2 reference signal indices of time instance T5 respectively, by the first CSI report. The network device can learn from the reporting of the first CSI report that the Top-2 reference signal indices of time instance T6 is [CRI-1+ offset value 1, CRI-2+ offset value 2]. Here, the CRI represents a CSI-RS resource indicator (CSI-RS Resource Indicator).

[117] In some embodiments, configuration parameters of the second CSI report include one or more of the following:a minimum reporting interval; a period of a reporting window; a number of reporting times within a reporting window; a time length of a reporting window.

[118] Specifically, the second CSI report for reporting the measurement result may be configured as non-strictly periodic (quasi-periodic) reporting or periodic reporting. When quasi-periodic reporting is configured, the network device may configure relevant parameters, such as the minimum reporting interval, the period of the reporting window, the number of reporting times within the reporting window, the time length of the reporting window, etc.

[119] Among them, the minimum reporting interval refers to the minimum time interval between two reporting instances of CSI reports. As shown in FIG. 1, the interval between two measurements is X ms. The minimum reporting interval of the second CSI report may be configured to X ms or an integer multiple of X ms, such as 2*X ms. The terminal may report the average result of every two measurements.

[120] The reporting window refers to the time period for reporting of CSI reports. CSI reports are reported within the reporting window, and no CSI reports are reported in the time period outside the reporting window.

[121] For example, as in FIG. 1, the time instances T1, T2, T3 and T4 are measurement time instances, and T5 and T6 are prediction time instances. The period of the measurement window is Y ms. The network device may configure the period of the reporting window to Y ms; or configure the number of reporting times within the reporting window to 4, that is, reporting of CSI reports is performed four times within one reporting window; or configure the time length of the reporting window to 4*X ms.

[122] In the present disclosure, quasi-periodic reporting refers to periodic reporting within some time periods and no reporting within other time periods. For example, it is assumed that the intervals between time instances T1′, T2′, T3′, T4′, T5′, T6′, T7′, T8′, T9′, T10′, T11′ and T12′ are all X ms. Reporting is performed at time instances T1′, T2’, T3′ and T4′, no reporting is performed at time instances T5′ and T6′, reporting is performed at time instances T7′, T8′, T9′ and T10′, and no reporting is performed at time instances T11′ and T12′. Such reporting characteristic is a non-strictly periodic characteristic, which may be referred to as a quasi-periodic characteristic. Of course, “quasi-periodic” may be expressed by other words, and the present disclosure is not limited to specific terms as long as the meaning of “quasi-periodic” can be expressed.

[123] In some embodiments, the method further includes:determining, based on a reference signal configuration associated with the second CSI report and the minimum reporting interval of the second CSI report, time instances for reporting the second CSI report and / or time instances for not reporting the second CSI report.

[124] For example, when the terminal determines based on the reference signal configuration that the current reporting and the previous reporting correspond to measurement resources of the same time instance, the terminal may not perform the current reporting, so as to save reporting overhead.

[125] In some embodiments, the reporting content of the third CSI report is any of the following:a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances;a prediction result of one time instance or a result obtained based on prediction results of a plurality of time instances.

[126] Specifically, the reporting of the third CSI report may have a plurality of different implementations. In one implementation, periodic reporting is used for the third CSI report, and the content reported by the terminal each time is a measurement result or a prediction result.

[127] Among them, for the measurement result of a single reporting, the measurement result may be the measurement result of one time instance or the result obtained based on measurement results of a plurality of time instances. The “result obtained based on measurement results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on measurement results of a plurality of time instances.

[128] For the prediction result of a single reporting, the prediction result may be the prediction result of one time instance or the result obtained based on prediction results of a plurality of time instances. The “result obtained based on prediction results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances.

[129] For example, as shown in FIG. 1, the base station configures the reporting period of the third CSI report to be X ms, and the reporting content to be the Top-K reference signal indices or the Top-K reference signal indices and L1-RSRP. When reporting the information of time instance T1 / T2 / T3 / T4, the terminal reports the Top-K reference signal indices obtained according to the measured reference signals of time instance T1 / T2 / T3 / T4 or reports the Top-K reference signal indices and the corresponding L1-RSRP. When reporting the information of time instance T5 / T6, the terminal reports the Top-K reference signal indices obtained according to the AI / ML model or reports the Top-K reference signal indices and the corresponding predicted L1-RSRP.

[130] In some embodiments, the reporting content of the third CSI report is:a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances, andprediction results of one or more time instances or a result obtained based on prediction results of a plurality of time instances.

[131] Specifically, in one implementation, periodic reporting is used for the third CSI report, and the content reported by the terminal each time is a measurement result and a prediction result.

[132] Among them, for the measurement result of a single reporting, the measurement result may be the measurement result of one time instance or the result obtained based on measurement results of a plurality of time instances. The “result obtained based on measurement results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on measurement results of a plurality of time instances.

[133] For the prediction result of a single reporting, the prediction result may be the prediction result of one time instance or the result obtained based on prediction results of a plurality of time instances. The “result obtained based on prediction results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances.

[134] For example, as shown in FIG. 2, the base station configures the reporting period of the third CSI report to be X ms. After completing the measurement of time instance T4, the terminal reports the Top-K reference signal indices of each of time instances T4, T5 and T6, or the Top-K reference signal indices of each of time instances T4, T5 and T6 and the corresponding L1-RSRP. Among them, the reporting content of time instance T4 is obtained according to the measured reference signals, and the reporting content of time instance T5 or T6 is obtained according to the prediction result of the AI / ML model. After the measurement of time instance T7 is completed, the beam information of each of time instances T7, T8 and T9 is reported, and so on.

[135] In some embodiments, the reporting content of the third CSI report is any of the following:a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances;a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances, and prediction results of one or more time instances;a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances, and a result obtained based on prediction results of a plurality of time instances.

[136] Specifically, in one implementation, quasi-periodic reporting is used for the third CSI report, and the content reported by the terminal each time is a measurement result, or a measurement result and a prediction result.

[137] The configuration parameters of the quasi-periodic reporting include one or more of the following: the minimum reporting interval, the period of the reporting window, the number of reporting times within the reporting window, or the time length of the reporting window.

[138] Among them, for the measurement result of a single reporting, the measurement result may be the measurement result of one time instance or the result obtained based on measurement results of a plurality of time instances. The “result obtained based on measurement results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on measurement results of a plurality of time instances.

[139] For the prediction result of a single reporting, the prediction result may be the prediction result of one time instance or the result obtained based on prediction results of a plurality of time instances. The “result obtained based on prediction results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances.

[140] For example, as shown in FIG. 1, the base station configures the minimum reporting interval of the third CSI report to be X ms, the period of the reporting window to be Y ms, and the number of reporting times within the reporting window to be 4. The terminal reports the Top-K reference signal indices or the Top-K reference signal indices and the corresponding L1-RSRP for time instances T1, T2 and T3 separately at an interval of X ms. After completing the measurement of time instance T4, the terminal reports the Top-K reference signal indices or the Top-K reference signal indices and the corresponding L1-RSRP for each of time instances T4, T5 and T6. Among them, the reporting content of time instance T4 is obtained according to the measured reference signals, and the reporting content of time instance T5 or T6 is obtained according to the prediction result of the AI / ML model. Reporting is completed four times every Y ms in the same way.

[141] In some embodiments, the method further includes:receiving a reference signal configuration transmitted by the network device, where the reference signal configuration includes one or more of the following configuration parameters of a reference signal:a minimum transmitting interval;a period of a transmitting window;a number of transmitting times of the reference signal within a transmitting window;a time length of a transmitting window;a number of transmitting times of the reference signal within one time window;a number of non- transmitting times of the reference signal within one time window;a time length of the time window.

[142] Specifically, in the case of beam prediction using the AI / ML technology, the reference signal may be transmitted in a non-strictly periodic manner. For example, the reference signal may not be transmitted at the prediction time instances shown in FIG. 1. This non-strictly periodic time-domain transmitting behavior, where the reference signal is transmitted periodically within some time periods and not transmitted within other time periods, may be referred to as quasi-periodic transmitting, and the reference signal may be referred to as a quasi-periodic reference signal. Similar to the quasi-periodic reporting described above, other words may be used instead of the expression of quasi-periodic, and the present disclosure is not limited thereto.

[143] The network device may configure relevant parameters of the quasi-periodic reference signal to the terminal, such as a minimum transmitting interval, a period of a transmitting window, a number of transmitting times of the reference signal within a transmitting window, a time length of a transmitting window, and the like.

[144] Here, the minimum transmitting interval refers to the minimum time interval between two transmissions of the reference signal. For example, the minimum transmitting interval of the reference signals in the reference signal set corresponding to SetA in FIG. 1 is X ms.

[145] The transmitting window refers to the time period in which the reference signal is transmitted, where the reference signal is transmitted within the transmitting window, and no reference signal is transmitted within the time period outside the transmitting window. In some embodiments, the time period of the measurement window is the same as that of the transmitting window. For example, the period of the transmitting window in FIG. 1 is Y ms, the number of transmitting times of the reference signal within each transmitting window is 4, or the time length of the transmitting window is 4*X ms.

[146] In some implementations, the network device may configure the minimum transmitting interval of the reference signal, and at least one of: the number of transmitting times of the reference signal within one time window, the number of non-transmitting times of the reference signal within one time window, or the time length of the time window. The terminal may know the time-domain behavior of the reference signal accordingly.

[147] In some implementations, the time length of the time window may be the time length of one period of the transmitting window, where the time window includes the transmitting window and a time period between two transmitting windows. For example, the time period T1~T7 shown in FIG. 1 may be one time window. Within this time window, the number of transmitting times of the reference signal is 4, and the number of non-transmitting times is 2.

[148] FIG. 4 is a schematic flowchart of a configuration method of beam information reporting provided by an embodiment of the present disclosure. The method is applied to a network device (for example, a base station). As shown in FIG. 4, the method includes the following steps.

[149] Step 400: transmitting configuration information of a channel state information CSI report to a terminal, where the CSI report includes a first CSI report, a second CSI report, or a third CSI report; where the first CSI report is used for reporting of a prediction result, the second CSI report is used for reporting of a measurement result, the third CSI report is used for reporting of a measurement result and a prediction result.

[150] Specifically, the beam information reporting in the present disclosure is based on a channel state information reporting (CSI reporting) framework. The network device configures the CSI report to be used for reporting a measurement result and / or a prediction result. Here, the CSI report includes a first CSI report for reporting of a prediction result, a second CSI report for reporting of a measurement result, or a third CSI report for reporting of a measurement result and a prediction result.

[151] In some implementations, the network device may configure different CSI reports for reporting the measurement result and the prediction result, respectively. For example, the first CSI report is configured for reporting of the prediction result, and the second CSI report is configured for reporting of the measurement result.

[152] In some implementations, the network device may configure the third CSI report for reporting the measurement result and the prediction result, that is, both the measurement result and the prediction result may be reported through the third CSI report.

[153] In some embodiments, the CSI report is associated with one or more reference signal resource sets. The one or more reference signal resource sets may be used for measurement and / or reporting. Among them, the reference signal resource set being used for measurement means that what is measured during the measurement are reference signals in the reference signal resource set. The reference signal resource set being used for reporting means that what is reported during the reporting is relevant information of reference signals in the reference signal resource set, such as index information of the optimal K reference signals in the reference signal resource set, signal quality information of the reference signals in the reference signal resource set, and the like.

[154] For example, the first CSI report is associated with one reference signal resource set, and the one reference signal resource set is used for both measurement and reporting. Alternatively, the first CSI report is associated with a plurality of reference signal resource sets, and the plurality of reference signal resource sets include a reference signal resource set for measurement and a reference signal resource set for reporting.

[155] For example, the second CSI report is associated with one reference signal resource set, and the one reference signal resource set is used for both measurement and reporting. Alternatively, the second CSI report is associated with a plurality of reference signal resource sets, and the plurality of reference signal resource sets include a reference signal resource set for measurement and a reference signal resource set for reporting.

[156] For example, the third CSI report is associated with one reference signal resource set, and the one reference signal resource set is used for both measurement and reporting. Alternatively, the third CSI report is associated with a plurality of reference signal resource sets, and the plurality of reference signal resource sets include a reference signal resource set for measurement and a reference signal resource set for reporting.

[157] In the present disclosure, the measurement result is information related to the optimal beams (pairs) obtained by the terminal through measuring reference signals, such as optimal K (Top-K) reference signal indices corresponding to the optimal beams, signal quality of reference signals corresponding to the Top-K reference signal indices, and other information. The prediction result is information related to the optimal beams (pairs) obtained by the terminal through performing beam prediction based on an AI / ML model (or AI / ML function, AI / ML engine, or the like), such as the optimal K (Top-K) reference signal indices corresponding to the optimal beams, the signal quality of the reference signals corresponding to the Top-K reference signal indices, and other information. The value of K may be configured by the network side, and K is an integer greater than or equal to 1.

[158] In some implementations, the signal quality includes L1-RSRP or L1-SINR, etc.

[159] By configuring the first CSI report, the second CSI report or the third CSI report to report the measurement result and / or the prediction result, the configuration method of beam information reporting provided in the embodiments of the present disclosure facilitates the use of AI / ML technology to save reference signal transmission resources, save terminal measurement overhead, and reduce terminal measurement delay, and can also adapt to the reporting requirements of different beam prediction modes, thereby improving the flexibility of beam management.

[160] In some embodiments, the reporting content of the first CSI report includes reference signal index information, and the reference signal index information is used for reporting predicted optimal reference signal indices of N time instances, where N is an integer greater than or equal to 1.

[161] For example, periodic reporting (the reporting period is configured) is used for the first CSI report. The terminal reports the predicted Top-K reference signal index information of N time instances in each time of reporting, and N is less than or equal to the number of prediction time instances output by the AI / ML model.

[162] In some embodiments, the reporting content of the first CSI report further includes predicted signal quality of reference signals corresponding to the predicted optimal reference signal indices of the N time instances (e.g., predicted L1-RSRP, L1-SINR, etc.).

[163] In some embodiments, a prediction result of one time instance reported by the terminal may be a prediction result of one time instance obtained by performing prediction according to reference signals associated with this CSI report and measured before the CSI reference resource, or a result obtained based on prediction results of a plurality of time instances (for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances).

[164] In some embodiments, the reference signal index information includes any of the following.

[165] (1) Predicted optimal K reference signal indices of each of the N time instances.

[166] For example, as shown in FIG. 1, after measuring the reference signals of time instance T4, the terminal predicts the Top-K reference signals for time instances T5 and T6 according to the AI / ML model, and reports the Top-K reference signal indices of time instance T5 and the Top-K reference signal indices of time instance T6 by the first CSI report; after measuring the reference signals of time instance T10, the terminal predicts the Top-K reference signals for time instances T11 and time T12 according to the AI / ML model, and reports the Top-K reference signal indices of time instance T11 and the Top-K reference signal indices of time instance T12 by the first CSI report.

[167] (2) Predicted optimal K reference signal indices of each of a part of the N time instances, and information of a time instance whose predicted optimal K reference signal indices are repeated. In this way, the reporting overhead can be reduced.

[168] In some implementations, the terminal may report prediction results of a part of the N time instances, where the Top-K reference signal indices of this part of the N time instances are not repeated. The terminal does not repeatedly report prediction results of other time instances, but indicates to the network device which time instances have the same Top-K reference signal indices (that is, there are repetitions).

[169] In some implementations, if the Top-K reference signal indices predicted by the terminal for a certain time instance are the same as the Top-K reference signal indices predicted for the previous time instance, the terminal may not perform repeated reporting, and indicate to the network device which time instances have the same Top-K reference signal indices.

[170] For example, as shown in FIG. 1, after measuring the reference signals of time instance T4, the terminal predicts the Top-K reference signals for time instances T5 and T6 according to the AI / ML model, and if the Top-K reference signals predicted for the time instances T5 and T6 are the same, the Top-K reference signal indices of time instance T5 and indication information [0 1] is reported by the first CSI report, where the second bit takes “1” to represent that the Top-K reference signal indices of the second time instance is the same as the Top-K reference signal indices of the first time instance. Here, reporting “ information of the time instance whose predicted optimal K reference signal indices are repeated” by the indication information [0 1] is merely an example, and the specific form of reporting “information of the time instance whose predicted optimal K reference signal indices are repeated” is not limited in the present disclosure.

[171] (3) Predicted optimal K reference signal indices of a reference time instance of the N time instances, and offset information of predicted optimal K reference signal indices of each of other time instances relative to the predicted optimal K reference signal indices of the reference time instance, where the other time instances include all of the N time instances except the reference time instance. In this way, the reporting overhead can be reduced.

[172] In some embodiments, the reference time instance may be the first time instance of the N time instances. The terminal reports the predicted Top-K reference signal indices of the reference time instance, and indicates the predicted Top-K reference signal indices for other time instances by offset information.

[173] For example, as shown in FIG. 1, after measuring the reference signals of time instance T4, the terminal predicts the Top-2 reference signals for time instances T5 and T6 according to the AI / ML model. The terminal reports the Top-2 reference signal indices [CRI-1, CRI-2] of the time instance T5 as well as offset values [offset value 1, offset value 2] of the Top-2 reference signal indices of time instanceT6 relative to the Top-2 reference signal indices of time instance T5 respectively, by the first CSI report. The network device can learn from the reporting of the first CSI report that the Top-2 reference signal indices of time instance T6 is [CRI-1+ offset value 1, CRI-2+ offset value 2].

[174] In some embodiments, configuration parameters of the second CSI report include one or more of the following:a minimum reporting interval; a period of a reporting window; a number of reporting times within a reporting window; a time length of a reporting window.

[175] Specifically, the second CSI report for reporting the measurement result may be configured as a non-strictly periodic (quasi-periodic) reporting or periodic reporting. When quasi-periodic reporting is configured, the network device may configure relevant parameters, such as the minimum reporting interval, the period of the reporting window, the number of reporting times within the reporting window, the time length of the reporting window, etc.

[176] Among them, the minimum reporting interval refers to the minimum time interval between two reporting instances of CSI reports. As shown in FIG. 1, the interval between two measurements is X ms. The minimum reporting interval of the second CSI report may be configured to X ms or an integer multiple of X ms, such as 2*X ms. The terminal may report the average result of every two measurements.

[177] The reporting window refers to the time period for reporting of CSI reports. CSI reports are reported within the reporting window, and no CSI reports are reported in the time period outside the reporting window.

[178] For example, as in FIG. 1, the time instances T1, T2, T3 and T4 are measurement time instances, and T5 and T6 are prediction time instances. The period of the measurement window is Y ms. The network device may configure the period of the reporting window to Y ms; or configure the number of reporting times within the reporting window to 4, that is, reporting of CSI reports is performed four times within one reporting window; or configure the time length of the reporting window to 4*X ms.

[179] In the present disclosure, quasi-periodic reporting refers to periodic reporting within some time periods and no reporting within other time periods. For example, it is assumed that the intervals between time instances T1′, T2′, T3′, T4′, T5′, T6′, T7′, T8′, T9′, T10′, T11′ and T12′ are all X ms. Reporting is performed at time instances T1′, T2’, T3′ and T4′, no reporting is performed at time instances T5′ and T6′, reporting is performed at time instances T7′, T8′, T9′ and T10′, and no reporting is performed at time instances T11′ and T12′. Such reporting characteristic is a non-strictly periodic characteristic, which may be referred to as a quasi-periodic characteristic. Of course, “quasi-periodic” may be expressed by other words, and the present disclosure is not limited to specific terms as long as the meaning of “quasi-periodic” can be expressed.

[180] In some embodiments, the method further includes:determining, based on a reference signal configuration associated with the second CSI report and the minimum reporting interval of the second CSI report, time instances for reporting the second CSI report and / or time instances for not reporting the second CSI report.

[181] For example, when terminal determines based on the reference signal configuration that the current reporting and the previous reporting correspond to measurement resources of the same time instance, the terminal may not perform the current reporting, so as to save reporting overhead.

[182] In some embodiments, the reporting content of the third CSI report is any of the following:a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances; a prediction result of one time instance or a result obtained based on prediction results of a plurality of time instances.

[183] Specifically, the reporting of the third CSI report may have a plurality of different implementations. In one implementation, periodic reporting is used for the third CSI report, and the content reported by the terminal each time is a measurement result or a prediction result.

[184] Among them, for the measurement result of a single reporting, the measurement result may be the measurement result of one time instance or the result obtained based on measurement results of a plurality of time instances. The “the result obtained based on measurement results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on measurement results of a plurality of time instances.

[185] For the prediction result of a single reporting, the prediction result may be the prediction result of one time instance or the result obtained based on prediction results of a plurality of time instances. The “result obtained based on prediction results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances.

[186] For example, as shown in FIG. 1, the base station configures the reporting period of the third CSI report to be X ms, and the reporting content to be the Top-K reference signal indices or the Top-K reference signal indices and L1-RSRP. When reporting the information of time instance T1 / T2 / T3 / T4, the terminal reports the Top-K reference signal indices obtained according to the measured reference signals of time instance T1 / T2 / T3 / T4 or reports the Top-K reference signal indices and the corresponding L1-RSRP. When reporting the information of time instance T5 / T6, the terminal reports the Top-K reference signal indices obtained according to the AI / ML model or reports the Top-K reference signal indices and the corresponding predicted L1-RSRP.

[187] In some embodiments, the reporting content of the third CSI report is:a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances, andprediction results of one or more time instances or a result obtained based on prediction results of a plurality of time instances.

[188] Specifically, in one implementation, periodic reporting is used for the third CSI report, and the content reported by the terminal each time is a measurement result and a prediction result.

[189] Among them, for the measurement result of a single reporting, the measurement result may be the measurement result of one time instance or the result obtained based on measurement results of a plurality of time instances. The “result obtained based on measurement results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on measurement results of a plurality of time instances.

[190] For the prediction result of a single reporting, the prediction result may be the prediction result of one time instance or the result obtained based on prediction results of a plurality of time instances. The “result obtained based on prediction results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances.

[191] For example, as shown in FIG. 2, the base station configures the reporting period of the third CSI report to be X ms. After completing the measurement of time instance T4, the terminal reports the Top-K reference signal indices of each of time instances T4, T5 and T6, or the Top-K reference signal indices of each of time instances T4, T5 and T6 and the corresponding L1-RSRP. Among them, the reporting content of time instance T4 is obtained according to the measured reference signals, and the reporting content of time instance T5 or T6 is obtained according to the prediction result of the AI / ML model. After the measurement of time instance T7 is completed, the beam information of each of time instances T7, T8 and T9 is reported, and so on.

[192] In some embodiments, the reporting content of the third CSI report is any of the following:a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances;a measurement result of one time instance or a result obtained based on the measurement results of a plurality of time instances, and prediction results of one or more time instances;a measurement result of one time instance or a result obtained based on measurement results of a plurality of time instances, and a result obtained based on prediction results of a plurality of time instances.

[193] Specifically, in one implementation, quasi-periodic reporting is used for the third CSI report, and the content reported by the terminal each time is a measurement result, or a measurement result and a prediction result.

[194] The configuration parameters of the quasi-periodic reporting include one or more of the following: the minimum reporting interval, the period of the reporting window, the number of reporting times within the reporting window, or the time length of the reporting window.

[195] Among them, for the measurement result of a single reporting, the measurement result may be the measurement result of one time instance or the result obtained based on measurement results of a plurality of time instances. The “result obtained based on measurement results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on measurement results of a plurality of time instances.

[196] For the prediction result of a single reporting, the prediction result may be the prediction result of one time instance or the result obtained based on prediction results of a plurality of time instances. The “result obtained based on prediction results of a plurality of time instances” may be, for example, a result obtained by performing time-domain filtering or averaging on prediction results of a plurality of time instances.

[197] For example, as shown in FIG. 1, the base station configures the minimum reporting interval of the third CSI report to be X ms, the period of the reporting window to be Y ms, and the number of reporting times within the reporting window to be 4. The terminal reports the Top-K reference signal indices or the Top-K reference signal indices and the corresponding L1-RSRP for time instances T1, T2 and T3 separately at an interval of X ms. After completing the measurement of time instance T4, the terminal reports the Top-K reference signal indices or the Top-K reference signal indices and the corresponding L1-RSRP for each of time instances T4, T5 and T6. Among them, the reporting content of time instance T4 is obtained according to the measured reference signals, and the reporting content of time instance T5 or T6 is obtained according to the prediction result of the AI / ML model. Reporting is completed four times every Y ms in the same way.

[198] In some embodiments, the method further includes:transmitting a reference signal configuration to the terminal, where the reference signal configuration includes one or more of the following configuration parameters of a reference signal:a minimum transmitting interval;a period of a transmitting window;a number of transmitting times of the reference signal within a transmitting window;a time length of a transmitting window;a number of transmitting times of the reference signal within one time window;a number of non-transmitting times of the reference signal within one time window; a time length of the time window.

[199] Specifically, in the case of beam prediction using the AI / ML technology, the reference signal may be transmitted in a non-strictly periodic manner. For example, the reference signal may not be transmitted at the prediction time instances shown in FIG. 1. This non-strictly periodic time-domain transmitting behavior, where the reference signal is transmitted periodically within some time periods and not transmitted within other time periods, may be referred to as quasi-periodic transmitting, and the reference signal may be referred to as a quasi-periodic reference signal. Similar to the quasi-periodic reporting described above, other words may be used instead of the expression of quasi-periodic, and the present disclosure is not limited thereto.

[200] The network device may configure relevant parameters of the quasi-periodic reference signal to the terminal, such as a minimum transmitting interval, a period of a transmitting window, a number of transmitting times of the reference signal within a transmitting window, a time length of a transmitting window, and the like.

[201] Here, the minimum transmitting interval refers to the minimum time interval between two transmissions of the reference signal. For example, the minimum transmitting interval of the reference signals in the reference signal set corresponding to SetA in FIG. 1 is X ms.

[202] The transmitting window refers to the time period in which the reference signal is transmitted, where the reference signal is transmitted within the transmitting window, and no reference signal is transmitted within the time period outside the transmitting window. In some embodiments, the time period of the measurement window is the same as that of the transmitting window. For example, the period of the transmitting window in FIG. 1 is Y ms, the number of transmitting times of the reference signal within each transmitting window is 4, or the time length of the transmitting window is 4*X ms.

[203] In some implementations, the network device may configure the minimum transmitting interval of the reference signal, and at least one of: the number of transmitting times of the reference signal within one time window, the number of non-transmitting times of the reference signal within one time window, or the time length of the time window. The terminal may know the time-domain behavior of the reference signal accordingly.

[204] In some implementations, the time length of the time window may be the time length of one period of the transmitting window, where the time window includes the transmitting window and a time period between two transmitting windows. For example, the time period T1~T7 shown in FIG. 1 may be one time window. Within this time window, the number of transmitting times of the reference signal is 4, and the number of non-transmitting times is 2.

[205] Since the methods provided in the embodiments of the present disclosure are based on the same application concept, for implementations of the methods, reference can be made to each other, and repeated details will not be described again.

[206] Hereinafter, methods provided by the above-described embodiments of the present disclosure will be described by way of examples of specific application scenarios.

[207] Example 1:

[208] In this example, the base station configures reference signal set#1. The reference signal set#1 includes eight CSI-RSs, and the reference signal parameters configured by the base station include:the minimum transmitting interval: 10 ms;the number of transmitting times of the reference signal within one time window: 2 times;the number of non-transmitting times of the reference signal within one time window: 2 times, or the time length of the time window: 40 ms.

[209] FIG. 5 is a schematic diagram of a transmitting time instance of reference signal set#1 provided by an embodiment of the present disclosure. According to the reference signal parameters configured by the base station, the terminal can know that the time-domain behavior of the base station transmitting the reference signals is as shown in FIG. 5, that is, the base station transmits the reference signal set#1 at time instances T1, T2, T5, T6, T9 and T10. The terminal measures the reference signals at these time instances based on the configuration information of the base station.

[210] Example 2:

[211] In this example, the base station configures that CSI report#1 is associated with the reference signal set#1 in FIG. 5, and the reporting content is K (Top-K) reference signal indices of the measured reference signals and the corresponding L1-RSRP. The CSI reporting parameters configured by the base station include:the minimum reporting interval: 10 ms;the period of the reporting window: 40 ms;the number of reporting times within the report window: 2.

[212] Alternatively, the base station configures the minimum reporting interval to 10 ms, and negotiates with the terminal, or specifies, that if the current reporting and the previous reporting correspond to the measurement resources of the same time instance, the terminal does not perform the current reporting.

[213] FIG. 6 is a first schematic diagram of a terminal reporting time instance provided by an embodiment of the present disclosure. According to the CSI reporting parameters configured by the base station, the terminal reports beam information according to the time instances in FIG. 6, that is, to report the reference signal measurement result of time instance T1 in FIG. 5 at time instance T1’, report the reference signal measurement result of time instance T2 at time instance T2’, not perform reporting at time instances T3’ and T4’, and so on.

[214] Example 3:

[215] In this example, the terminal reports to the base station that time-domain beam prediction can be performed based on the AI / ML model / AI function. The measurement window includes two measurement time instances. The interval between measurement time instances is 10 ms. The prediction window includes two prediction time instances. The interval between prediction time instances is 10 ms. That is, the optimal beams of two future time instances are predicted based on the measurement results of two time instances. The base station configures CSI report#2 to be associated with the reference signal set#1 in FIG. 5. The reporting content is the reference signal indices corresponding to the optimal beams of each of the two prediction time instances. If the optimal reference signal indices of a certain time instance are the same as the optimal reference signal indices of the previous time instance, repeated reporting is not performed.

[216] The terminal measures the reference signals of time instances T1 and T2 in FIG. 5, and obtains the reference signal indices corresponding to the optimal beams of time instances T3 and T4 according to the AI / ML model / AI function.

[217] If the reference signal indices corresponding to the optimal beams of time instances T3 and T4 are both CRI#1, the terminal reports CRI#1 and [0 1], where the second bit takes “1” to represent that the Top-K reference signal indices of the second time instance is the same as the Top-K reference signal indices of the first time instance.

[218] If the reference signal indices corresponding to the optimal beams of time instances T3 and T4 are CRI#1 and CRI#2, respectively, the terminal reports CRI#1, CRI#2, and [0 0].

[219] Example 4:

[220] In this example, the base station configures CSI report#2 according to the AI / ML model / AI function related information reported by the terminal, and the CSI report#2 is associated with the reference signal set#1 in FIG. 5 (same as Example 3). The reporting content is the reference signal index corresponding to the predicted optimal beam of the first time instance in the two prediction time instances and the offset value of the second time instance relative to the reported reference signal index of the first time instance.

[221] For example, it is assumed that the reference signal set#1 includes eight reference signals. The reference signal index corresponding to the optimal beam of the first time instance may be expressed by 3 bits (that is, indicating which reference signal is optimal among the eight reference signals). The offset value of the reference signal index corresponding to the optimal beam of the second time instance relative to the reported index of the first time instance is represented by two bits, for example:00 indicates that the reference signal index offset is 0, that is, the same as the optimal index of the previous time instance;01 indicates that the reference signal index offset is 1, and if the optimal reference signal index of the previous time instance is the i-th, the optimal reference signal index of this time instance is the (i +1)-th;10 indicates that the reference signal index offset is −1, and if the optimal reference signal index of the previous time instance is the i-th, the optimal reference signal index of this time instance is the (i-1)-th;11 indicates that the reference signal index offset is 2, and if the optimal reference signal index of the previous time instance is the i-th, the optimal reference signal index of this time instance is the (i +2)-th.

[222] Example 5:

[223] In this example, the terminal reports to the base station that time-domain beam prediction can be performed based on the AI / ML model / AI function. The length of the measurement window is 2 (including 2 measurement time instances). The length of the prediction window is 2 (including 2 prediction time instances). The period of the measurement time instance is the same as the period of the prediction time instance. That is, the optimal beams of two future time instances are predicted based on the measurement results of two time instances. The base station configures that CSI report#3 is associated with the reference signal set#1 in FIG. 5, the reporting period is 10 ms, and the reporting content is the reference signal indices corresponding to the measured or predicted optimal K beams.

[224] FIG. 7 is a second schematic diagram of a terminal reporting time instance provided by an embodiment of the present disclosure. According to the above information, the terminal reports beam information according to the time instances in FIG. 7, that is, to report K reference signal indices obtained according to the reference signal measurement results of time instance T1 in FIG. 5 at time instance T1’, report K reference signal indices obtained according to the reference signal measurement results of time instance T2 in FIG. 5 at time instance T2’, report K reference signal indices that correspond to time instance T3 and are predicted according to the AI / ML model at time instance T3’, report K reference signal indices that correspond to time instance T4 and are predicted according to the AI / ML model at time instance T4’, and so on.

[225] Example 6:

[226] In this example, the terminal reports to the base station that time-domain beam prediction can be performed based on the AI / ML model / AI function, and the input and output of the AI / ML model / AI function are the same as in Example 3. The base station configures that CSI report#3 is associated with the reference signal set#1 in FIG. 5, the minimum reporting interval is 10 ms, the period of the reporting window is 40 ms, and the number of reporting times within the reporting window is 2 times.

[227] FIG. 8 is a third schematic diagram of a terminal reporting time instance provided by an embodiment of the present disclosure. According to the above information, the terminal reports beam information according to the time instances in FIG. 8. Here:K reference signal indices obtained according to the reference signal measurement results of time instance T1 in FIG. 5 are reported at time instance T1’;K reference signal indices obtained according to the reference signal measurement results of time instance T2 in FIG. 5, K reference signal indices that correspond to time instance T3 and are predicted according to the AI / ML model, and K reference signal indices that correspond to time instance T4 and are predicted according to the AI / ML model are reported at time T2’.

[228] Reporting is performed in the above manner every 40 ms.

[229] Example 7:

[230] In this example, the terminal reports to the base station that time-domain beam prediction can be performed based on the AI / ML model / AI function. The measurement window includes two measurement time instances with a measurement interval of 30 ms, and the prediction window includes two prediction time instances with an interval of 10 ms.

[231] The base station configures CSI report#4 as periodic reporting according to the information reported by the terminal, and the reporting period is 30 ms. FIG. 9 is an example diagram of a transmitting time instance of reference signal set#2 provided by an embodiment of the present disclosure. As shown in FIG. 9, the base station transmits the reference signal set#2 at time instances T1, T4, T7 and T10. The CSI report#4 is associated with the reference signal set#2 in FIG. 9, and the reporting content is the reference signal indices corresponding to the optimal beams of each of the three time instances, where for the first time instance, the reference signal indices are obtained according to measurement, and for the second and third time instances, the reference signal indices are obtained according to prediction.

[232] FIG. 10 is a fourth schematic diagram of a terminal reporting time instance provided by an embodiment of the present disclosure. According to the configuration information of the base station, the terminal performs reporting according to the time instances in FIG. 10, where K reference signal indices obtained according to the reference signal measurement results of time instance T1 in FIG. 9, K reference signal indices that correspond to time instance T2 and are predicted according to the AI / ML model, K reference signal indices that correspond to time instance T3 and are predicted according to the AI / ML model are reported at time instance T1’, and so on. That is, for each reporting instance, the result of one measurement time instance and the results of two prediction time instances are reported.

[233] It should be noted that, in each of the above examples, when reporting the measurement results and the prediction results, the reporting content may include not only the reference signal indices, but also the signal quality (e.g., L1-RSRP) of the reference signals corresponding to the reference signal indices.
