[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

Technical Field

[0004] In New Radio (NR) systems, to combat path loss in high-frequency scenarios, the transmitter and receiver use beam management (BM) to obtain matching beam pairs to improve beamforming gain. The base station needs to send Channel State Information Reference Signals (CSI-RS) or Synchronization Signal Blocks (SSB) on all transmit beams (Tx beams), which consumes a large amount of reference signal resources. At the same time, the terminal needs to use all receive beams (Rx beams) to measure the CSI-RS or SSB sent on all Tx beams, resulting in a large measurement overhead. To address these issues, artificial intelligence (AI) or machine learning (ML) technologies are introduced to predict or infer the optimal beam (pair) based on the measurement results of some beams (pairs) or historical beam (pairs), thereby saving reference signal transmission resources, reducing terminal measurement overhead, and reducing terminal measurement latency.

[0166] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0167] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0168] In the embodiments of the present disclosure, the terms "first," "second," and the like are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than that illustrated or described herein. Furthermore, the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more.

[0169] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0170] In order to facilitate a clearer understanding of the technical solutions of the various embodiments of the present disclosure, some technical contents related to the various embodiments of the present disclosure are first introduced.

[0171] In the NR system, in order to combat the path loss in high-frequency scenarios, the transmitter and receiver obtain matching beam pairs through beam management to improve the beamforming gain. In the downlink beam management process of the related technology, the base station needs to cyclically send Tx beams in different directions, and the terminal uses Rx beams to receive Tx beams, and measures the CSI-RS or SSB signals sent on all Tx beams, and selects the K beams (such as K = 1, 2, 4) with the best reception performance (such as Layer 1 Reference Signal Received Power (L1-RSRP)), and reports the reference signal index information corresponding to these K beams to the base station. The base station selects a suitable Tx beam for subsequent communication based on the information reported by the terminal, and indicates the selected beam information to the terminal.

[0172] To obtain the optimal beam pair, the base station needs to transmit CSI-RS or SSB on all transmit beams, which consumes a lot of reference signal resources. Furthermore, the terminal needs to use all receive beams to measure the CSI-RS or SSB transmitted on all transmit beams, resulting in high measurement overhead. To address these issues, AI / ML technology is introduced to predict the optimal beam pair based on measurements of some beams (pairs) or historical beam (pair) measurements. This saves reference signal transmission resources, reduces terminal measurement overhead, and reduces terminal measurement latency.

[0173] The following describes two sub-use cases of AI beam management in related technologies:

[0174] BM-case 1 (Beam Management Sub-case 1): Spatial beam prediction, that is, predicting the top-K beams in beam set A (SetA) based on beam set B (SetB) measured at a certain moment.

[0175] BM-case 2 (Beam Management Sub-case 2): Time-domain beam prediction, that is, predicting the optimal K (Top-K) beams in the SetA beam set at the next M moments based on the SetB beam set measured at the past L moments.

[0176] In the BM-case2 time-domain beam prediction sub-use case, the relationship between SetB and SetA includes the following situations:

[0177] (1) SetA = SetB.

[0178] (2) SetB is a subset of SetA.

[0179] (3) Set B is a wide beam, and Set A is a narrow beam.

[0180] For time domain beam prediction, there are two prediction methods:

[0181] Prediction Method 1: The period of measurement moments in the measurement window is the same as the period of prediction moments in the prediction window. Figure 1 shows an example of Prediction Method 1 provided by related art. As shown in Figure 1, the input to the AI / ML model is the SetB beam measurement values ​​at four moments, with a measurement period of X ms. The output of the AI / ML model is the optimal K beams of SetA beams for the next two moments, with the interval between the two prediction moments also being X ms.

[0182] Prediction Method 2: The measurement period is greater than the prediction period. Figure 2 shows an example of prediction method 2, as provided by the related art. As shown in Figure 2, the optimal K beams of Set A at times T5 and T6 are predicted based on the Set B beams measured at times T1 and T4. The optimal K beams of Set A at times T8 and T9 are predicted based on the measurements at times T4 and T7. The measurement period is X milliseconds, and the interval between the two predicted times is Y milliseconds, where X is greater than Y.

[0183] Consider the case where SetB = SetA and an AI / ML model is deployed on the terminal side. In prediction method 1 in Figure 1, the Top-K beams in SetA at times T1 / T2 / T3 / T4 / T7 / T8 / T9 / T10 are obtained based on the L1-RSRP of SetA measured by the terminal. The Top-K beams at times T5 / T6 / T11 / T12 are predicted using the AI / ML model. In Figure 2, the Top-K beams at times T1 / T4 / T7 / T10 are obtained based on the L1-RSRP of SetA measured by the terminal, while the Top-K beams at other times are predicted using the AI / ML model. The terminal needs to report the Top-K beam-related information obtained through measurement or prediction to the base station so that the base station can select the optimal beam for downlink transmission.

[0184] In the related art, beam information reporting is based on the channel state information reporting (CSI reporting) framework. Each CSI report (CSI report) is associated with one measurement resource set (when multi-point transmission (Multi-TRP) is not considered), and the terminal reports the index of the best K reference signals in the measurement resource set and the corresponding L1-RSRP or Layer 1 Signal to Interference and Noise Ratio (L1-SINR). CSI reporting can be performed periodically, semi-persistently, or aperiodically. 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 the result of the last measurement before the CSI reference resource (CSI reference resource) (instantaneous result) or the result after filtering the results of multiple measurements before the CSI reference resource (average result). Whether filtering is performed depends on the configuration on the base station side.

[0185] FIG3 is a flow chart of a beam information reporting method according to an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG3 , the method includes the following steps:

[0186] Step 300: Receive configuration information of a channel state information (CSI) report sent by a network device, where the CSI report includes a first CSI report, a second CSI report, or a third CSI report; wherein the first CSI report is used for reporting prediction results, the second CSI report is used for reporting measurement results, and the third CSI report is used for reporting both measurement results and prediction results.

[0187] Step 301: Report measurement results and / or prediction results based on the configuration information of the CSI report.

[0188] Specifically, the beam information reporting in the present disclosure is based on the channel state information reporting (CSI reporting) framework, and the network device (for example, a base station) configures a CSI report for reporting measurement results and / or prediction results, wherein the CSI report includes a first CSI report for reporting prediction results, a second CSI report for reporting measurement results, or a third CSI report for reporting measurement results and prediction results.

[0189] It should be noted that in this disclosure, "prediction" can be replaced with terms of similar meanings such as "inference" and "inference". For example, "prediction result" can be replaced with "inference result" or "inference result".

[0190] In some implementations, the network device may configure different CSI reports for reporting measurement results and prediction results, respectively. For example, a first CSI report may be configured for reporting prediction results, and a second CSI report may be configured for reporting measurement results.

[0191] In some implementations, the network device may configure a third CSI report for reporting measurement results and prediction results, that is, both measurement results and prediction results may be reported through the third CSI report.

[0192] In some embodiments, a CSI report is associated with one or more reference signal resource sets. The one or more reference signal resource sets can be used for measurement and / or reporting. The use of a reference signal resource set for measurement means that the reference signals in the reference signal resource set are measured during measurement. The use of a reference signal resource set for reporting means that information related to the reference signals in the reference signal resource set is reported during reporting, such as index information of the best K reference signals in the reference signal resource set, signal quality information of the reference signals in the reference signal resource set, etc.

[0193] For example, the first CSI report is associated with a reference signal resource set, which is used for both measurement and reporting; or, the first CSI report is associated with multiple reference signal resource sets, which include a reference signal resource set for measurement and a reference signal resource set for reporting.

[0194] For example, the second CSI report is associated with a reference signal resource set, which is used for both measurement and reporting; or, the second CSI report is associated with multiple reference signal resource sets, which include a reference signal resource set for measurement and a reference signal resource set for reporting.

[0195] For example, the third CSI report is associated with a reference signal resource set, which is used for both measurement and reporting; or, the third CSI report is associated with multiple reference signal resource sets, which include a reference signal resource set for measurement and a reference signal resource set for reporting.

[0196] In the present disclosure, the measurement result is information related to the optimal beam (pair) obtained by the terminal through measurement of the reference signal, such as the optimal K (Top-K) reference signal indices corresponding to the optimal beam, the signal quality of the reference signal corresponding to the Top-K reference signal indices, and other information. The prediction result is information related to the optimal beam (pair) obtained by the terminal through beam prediction based on the AI / ML model (or AI / ML function, AI / ML engine, etc.), such as the optimal K (Top-K) reference signal indices corresponding to the optimal beam, the signal quality of the reference signal corresponding to the Top-K reference signal indices, and other information. The value of K can be configured by the network side, and K is an integer greater than or equal to 1.

[0197] In some implementations, the signal quality includes L1-RSRP or L1-SINR, etc.

[0198] The beam information reporting method provided in the embodiments of the present disclosure, by configuring the first CSI report, the second CSI report, or the third CSI report for reporting measurement results and / or prediction results, is conducive to using AI / ML technology to save reference signal transmission resources, save terminal measurement overhead, and reduce terminal measurement latency. It can also adapt to the reporting requirements of different beam prediction methods, thereby improving the flexibility of beam management.

[0199] In some embodiments, the reporting content of the first CSI report includes reference signal index information, where the reference signal index information is used to report the predicted optimal reference signal index at N time moments, where N is an integer greater than or equal to 1.

[0200] For example, the first CSI report is periodically reported (configured reporting period), and each time the terminal reports the predicted Top-K reference signal index information of N moments, where N is less than or equal to the number of predicted moments output by the AI / ML model.

[0201] It should be noted that, in the present disclosure, "moment" can refer to a specific time point or a period of time, and can be replaced with terms with similar meanings such as "time", "time instance", "slot interval(s)", etc.

[0202] In some embodiments, the reporting content of the first CSI report further includes the predicted signal quality (eg, predicted L1-RSRP, L1-SINR, etc.) of the reference signal corresponding to the predicted optimal reference signal index at N time moments.

[0203] In some embodiments, the prediction result of a moment reported by the terminal can be a prediction result of a moment obtained by predicting a reference signal associated with the CSI report measured before the CSI reference resource, or a result obtained based on the prediction results of multiple moments (for example, the result obtained by time domain filtering or averaging the prediction results of multiple moments).

[0204] In some embodiments, the reference signal index information includes any of the following:

[0205] (1) The predicted optimal K reference signal indices at each of the N time moments.

[0206] For example, taking Figure 1 as an example, after measuring the reference signal at time T4, the terminal predicts the Top-K reference signals at times T5 and T6 based on the AI / ML model, and reports the Top-K reference signal index at time T5 and the Top-K reference signal index at time T6 through the first CSI report. After measuring the reference signal at time T10, the terminal predicts the Top-K reference signals at times T11 and T12 based on the AI / ML model, and reports the Top-K reference signal index at time T11 and the Top-K reference signal index at time T12 through the first CSI report.

[0207] (2) The predicted optimal K reference signal indices at some of the N moments, and the predicted optimal K reference signal indices have repeated time information. This method can reduce reporting overhead.

[0208] In some implementations, the terminal may report the prediction results of some moments in N moments where the Top-K reference signal indexes are not repeated, and not report the prediction results of other moments repeatedly, but instead indicate to the network device which moments have the same Top-K reference signal indexes (i.e., there are repetitions).

[0209] In some implementations, if the Top-K reference signal index predicted by the terminal at a certain moment is the same as the Top-K reference signal index predicted at the previous moment, it may not be reported repeatedly, and the network device may be instructed as to which moments have the same Top-K reference signal index.

[0210] For example, taking Figure 1 as an example, after measuring the reference signal at time T4, the terminal predicts the Top-K reference signals at times T5 and T6 based on the AI / ML model. If the predicted Top-K reference signals at times T5 and T6 are the same, the Top-K reference signal index at time T5 is reported through the first CSI report and the indication information [0 1] is reported. The second bit is "1" to represent that the Top-K reference signal index at the second moment is the same as the Top-K reference signal index at the first moment. Reporting "the predicted optimal K reference signal index has repeated moment information" through the indication information [0 1] here is only an example. The present disclosure does not limit the specific form of reporting "the predicted optimal K reference signal index has repeated moment information".

[0211] (3) The predicted optimal K reference signal indices at the reference time among the N time moments, and the offset information of the predicted optimal K reference signal indices at other time moments relative to the predicted optimal K reference signal indices at the reference time, where the other time moments include all other time moments among the N time moments except the reference time. This method can reduce reporting overhead.

[0212] In some implementations, the reference moment may be the first of N moments, and the terminal reports the predicted Top-K reference signal index of the reference moment. The predicted Top-K reference signal indexes of other moments are indicated by offset information.

[0213] For example, as shown in Figure 1, after measuring the reference signal at time T4, the terminal predicts the top-2 reference signals at times T5 and T6 based on the AI / ML model. The terminal reports the top-2 reference signal index at time T5 [CRI-1, CRI-2] and the offset values ​​of the top-2 reference signal index at time T6 relative to the top-2 reference signal index at time T5 [offset 1, offset 2] through the first CSI report. The network device knows from the first CSI report that the top-2 reference signal index at time T6 is [CRI-1 + offset 1, CRI-2 + offset 2]. CRI stands for CSI-RS Resource Indicator.

[0214] In some embodiments, the configuration parameters of the second CSI report include one or more of the following:

[0215] Minimum reporting interval; reporting window period; number of reports within the reporting window; length of the reporting window.

[0216] Specifically, the second CSI report used to report the measurement results can be configured as non-strict periodic (quasi-periodic) reporting or periodic reporting. When configured as quasi-periodic reporting, the network device can configure relevant parameters such as the minimum reporting interval, the period of the reporting window, the number of reports within the reporting window, and the duration of the reporting window.

[0217] Among them, the minimum reporting interval refers to the minimum time interval between two CSI reports. As shown in Figure 1, the interval between the two measurements is Xms. The minimum reporting interval of the second CSI report can be configured as Xms, or as an integer multiple of Xms, such as 2*Xms. The terminal can report the average result of every two measurements.

[0218] The reporting window refers to the time period for reporting CSI reports. CSI reports are reported within the reporting window, and are not reported during the time period outside the reporting window.

[0219] For example, as shown in Figure 1, T1, T2, T3, and T4 are measurement moments, T5 and T6 are prediction moments, the measurement window period is Yms, and the network device can configure the reporting window period to be Yms; or, configure the number of reports within the reporting window to be 4, that is, report 4 CSI reports within one reporting window; or, configure the time length of the reporting window to be 4*Xms.

[0220] In the present disclosure, quasi-periodic reporting refers to periodic reporting in some time periods and no reporting in other time periods. For example, assuming that the intervals between T1′, T2′, T3′, T4′, T5′, T6′, T7′, T8′, T9′, T10′, T11′, and T12′ are all Xms, reporting is performed at T1′, T2′, T3′, and T4′, but not at T5′ and T6′, reporting is performed at T7′, T8′, T9′, and T10′, but not at T11′ and T12′. This reporting characteristic is a non-strict periodic characteristic and can be called a quasi-periodic characteristic. Of course, "quasi-periodic" can also be expressed using other words, as long as the meaning of "quasi-periodic" can be expressed. This disclosure does not limit the specific words.

[0221] In some embodiments, the method further comprises:

[0222] A time for reporting the second CSI report and / or a time for not reporting the second CSI report is determined based on the reference signal configuration associated with the second CSI report and the minimum reporting interval of the second CSI report.

[0223] For example, when the terminal determines, based on the reference signal configuration, that a certain report corresponds to measurement resources at the same time as a previous report, the terminal may not perform this report, thereby saving reporting overhead.

[0224] In some embodiments, the reporting content of the third CSI report is any one of the following:

[0225] A measurement result at one moment or a result based on measurement results at multiple moments;

[0226] The prediction result at one moment or the result obtained based on the prediction results at multiple moments.

[0227] Specifically, there are multiple different implementations for reporting the third CSI report. In one implementation, the third CSI report is periodically reported, and the content reported by the terminal each time is a measurement result or a prediction result.

[0228] For a single reported measurement result, the measurement result may be a measurement result at a single moment or a result obtained based on measurement results at multiple moments. "A result obtained based on measurement results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the measurement results at multiple moments.

[0229] For a single reported prediction result, the prediction result may be a prediction result at a single moment or a result obtained based on prediction results at multiple moments. The "result obtained based on prediction results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the prediction results at multiple moments.

[0230] For example, as shown in Figure 1, the base station configures the reporting period of the third CSI report to be Xms, and the reported content is the Top-K reference signal index or the Top-K reference signal index and L1-RSRP. When the terminal reports information at time T1 / T2 / T3 / T4, it reports the Top-K reference signal index or the Top-K reference signal index and the corresponding L1-RSRP obtained based on the measured reference signal at time T1 / T2 / T3 / T4. When the terminal reports information at time T5 / T6, it reports the Top-K reference signal index or the Top-K reference signal index obtained based on the AI / ML model and the corresponding predicted L1-RSRP.

[0231] In some embodiments, the reporting content of the third CSI report is:

[0232] A measurement result at one moment in time or a result based on measurement results at multiple moments in time; and

[0233] The prediction results at one or more moments or the results obtained based on the prediction results at multiple moments.

[0234] Specifically, in one implementation, the third CSI report is periodically reported, and the content reported by the terminal each time is a measurement result and a prediction result.

[0235] For a single reported measurement result, the measurement result may be a measurement result at a single moment or a result obtained based on measurement results at multiple moments. "A result obtained based on measurement results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the measurement results at multiple moments.

[0236] For a single reported prediction result, the prediction result may be a prediction result for one or more time periods or a result obtained based on the prediction results for multiple time periods. "A result obtained based on the prediction results for multiple time periods" may, for example, be a result obtained by time-domain filtering or averaging the prediction results for multiple time periods.

[0237] For example, as shown in Figure 2, the base station configures the reporting period of the third CSI report to be Xms. After completing the measurement at time T4, the terminal reports the Top-K reference signal index or Top-K reference signal index and the corresponding L1-RSRP at time T4, T5, and T6. The report content at time T4 is obtained based on the measured reference signal, and the report content at time T5 or T6 is obtained based on the prediction results of the AI / ML model. After completing the measurement at time T7, the beam information at time T7, T8, and T9 is reported, and so on.

[0238] In some embodiments, the reporting content of the third CSI report is any one of the following:

[0239] A measurement result at one moment or a result based on measurement results at multiple moments;

[0240] A measurement result at a moment in time or a result based on measurement results at multiple moments in time, as well as a prediction result at one or more moments in time;

[0241] A measurement result at one moment or a result based on measurement results at multiple moments, as well as a result based on prediction results at multiple moments.

[0242] Specifically, in one implementation, the third CSI report is quasi-periodic reporting, and the content reported by the terminal each time is a measurement result, or a measurement result and a prediction result.

[0243] The configuration parameters of quasi-periodic reporting include one or more of the following: minimum reporting interval, reporting window period, number of reports within the reporting window, and time length of the reporting window.

[0244] For a single reported measurement result, the measurement result may be a measurement result at a single moment or a result obtained based on measurement results at multiple moments. "A result obtained based on measurement results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the measurement results at multiple moments.

[0245] For a single reported prediction result, the prediction result may be a prediction result for one or more time periods or a result obtained based on the prediction results for multiple time periods. "A result obtained based on the prediction results for multiple time periods" may, for example, be a result obtained by time-domain filtering or averaging the prediction results for multiple time periods.

[0246] For example, as shown in Figure 1, the base station configures the minimum reporting interval of the third CSI report to be Xms, the reporting window period to be Yms, and the number of reports within the reporting window to be 4. The terminal reports the Top-K reference signal index or Top-K reference signal index and the corresponding L1-RSRP at times T1, T2, and T3 at intervals of Xms. After completing the measurement at time T4, the terminal reports the Top-K reference signal index or Top-K reference signal index and the corresponding L1-RSRP at times T4, T5, and T6. The report content at time T4 is obtained based on the measured reference signal, and the report content at time T5 or T6 is obtained based on the prediction results of the AI / ML model. This is analogous to complete the four reports within each Yms.

[0247] In some embodiments, the method further comprises:

[0248] Receive a reference signal configuration sent by a network device, where the reference signal configuration includes one or more of the following reference signal configuration parameters:

[0249] Minimum sending interval;

[0250] The period of the sending window;

[0251] The number of times the reference signal is sent within the sending window;

[0252] The length of the send window;

[0253] The number of times the reference signal is sent within a time window;

[0254] The number of times the reference signal is not sent within a time window;

[0255] The length of the time window.

[0256] Specifically, when AI / ML technology is used for beam prediction, the reference signal can be sent non-strictly periodically. For example, the reference signal may not be sent at the prediction moment shown in Figure 1. This non-strictly periodic time domain transmission behavior, in which the reference signal is sent periodically in some time periods and not sent in other time periods, can be referred to as quasi-periodic transmission, and the reference signal can be referred to as a quasi-periodic reference signal. Similar to the quasi-periodic reporting described above, other terms can be used to replace the expression of quasi-periodicity, and this disclosure does not limit it.

[0257] The network device can configure the terminal with relevant parameters of the quasi-periodic reference signal, such as the minimum sending interval, the period of the sending window, the number of times the reference signal is sent within the sending window, the time length of the sending window, etc.

[0258] The minimum transmission interval refers to the minimum time interval between two transmissions of a reference signal. For example, the minimum transmission interval of each reference signal in the reference signal set corresponding to SetA in FIG1 is X ms.

[0259] The transmission window refers to the time period during which a reference signal is transmitted. Reference signals are transmitted within the transmission window, and are not transmitted outside the transmission window. In some embodiments, the measurement window and the transmission window have the same time period. For example, in Figure 1 , the transmission window period is Y ms, and the number of reference signal transmissions within each transmission window is 4, or the transmission window duration is 4*X ms.

[0260] In some implementations, the network device may configure the minimum reference signal transmission interval, as well as at least one of the number of reference signal transmissions within a time window, the number of reference signal non-transmissions within a time window, and the time length of the time window, so that the terminal can learn the time domain behavior of the reference signal.

[0261] In some implementations, the time window may be the length of one period of a transmission window, where the time window includes the transmission window and the time period between two transmission windows. For example, the time period T1 to T7 shown in FIG1 may be one time window, where the reference signal is transmitted four times and not transmitted two times.

[0262] FIG4 is a flow chart of a method for configuring beam information reporting according to an embodiment of the present disclosure. The method is applied to a network device (e.g., a base station). As shown in FIG4 , the method includes the following steps:

[0263] Step 400: Send configuration information of a channel state information (CSI) report to the terminal, where the CSI report includes a first CSI report, a second CSI report, or a third CSI report; wherein the first CSI report is used to report prediction results, the second CSI report is used to report measurement results, and the third CSI report is used to report both measurement results and prediction results.

[0264] Specifically, the beam information reporting in the present disclosure is based on the channel state information reporting (CSI reporting) framework, and the network device configures the CSI report for reporting measurement results and / or prediction results, wherein the CSI report includes a first CSI report for reporting prediction results, a second CSI report for reporting measurement results, or a third CSI report for reporting measurement results and prediction results.

[0265] In some implementations, the network device may configure different CSI reports for reporting measurement results and prediction results, respectively. For example, a first CSI report may be configured for reporting prediction results, and a second CSI report may be configured for reporting measurement results.

[0266] In some implementations, the network device may configure a third CSI report for reporting measurement results and prediction results, that is, both measurement results and prediction results may be reported through the third CSI report.

[0267] In some embodiments, a CSI report is associated with one or more reference signal resource sets. The one or more reference signal resource sets can be used for measurement and / or reporting. The use of a reference signal resource set for measurement means that the reference signals in the reference signal resource set are measured during measurement. The use of a reference signal resource set for reporting means that information related to the reference signals in the reference signal resource set is reported during reporting, such as index information of the best K reference signals in the reference signal resource set, signal quality information of the reference signals in the reference signal resource set, etc.

[0268] For example, the first CSI report is associated with a reference signal resource set, which is used for both measurement and reporting; or, the first CSI report is associated with multiple reference signal resource sets, which include a reference signal resource set for measurement and a reference signal resource set for reporting.

[0269] For example, the second CSI report is associated with a reference signal resource set, which is used for both measurement and reporting; or, the second CSI report is associated with multiple reference signal resource sets, which include a reference signal resource set for measurement and a reference signal resource set for reporting.

[0270] For example, the third CSI report is associated with a reference signal resource set, which is used for both measurement and reporting; or, the third CSI report is associated with multiple reference signal resource sets, which include a reference signal resource set for measurement and a reference signal resource set for reporting.

[0271] In the present disclosure, the measurement result is information related to the optimal beam (pair) obtained by the terminal through measurement of the reference signal, such as the optimal K (Top-K) reference signal indices corresponding to the optimal beam, the signal quality of the reference signal corresponding to the Top-K reference signal indices, and other information. The prediction result is information related to the optimal beam (pair) obtained by the terminal through beam prediction based on the AI / ML model (or AI / ML function, AI / ML engine, etc.), such as the optimal K (Top-K) reference signal indices corresponding to the optimal beam, the signal quality of the reference signal corresponding to the Top-K reference signal indices, and other information. The value of K can be configured by the network side, and K is an integer greater than or equal to 1.

[0272] In some implementations, the signal quality includes L1-RSRP or L1-SINR, etc.

[0273] The beam information reporting method provided in the embodiments of the present disclosure, by configuring the first CSI report, the second CSI report, or the third CSI report for reporting measurement results and / or prediction results, is conducive to using AI / ML technology to save reference signal transmission resources, save terminal measurement overhead, and reduce terminal measurement latency. It can also adapt to the reporting requirements of different beam prediction methods, thereby improving the flexibility of beam management.

[0274] In some embodiments, the reporting content of the first CSI report includes reference signal index information, where the reference signal index information is used to report the predicted optimal reference signal index at N time moments, where N is an integer greater than or equal to 1.

[0275] For example, the first CSI report is periodically reported (configured reporting period), and each time the terminal reports the predicted Top-K reference signal index information of N moments, where N is less than or equal to the number of predicted moments output by the AI / ML model.

[0276] In some embodiments, the reporting content of the first CSI report further includes the predicted signal quality (eg, predicted L1-RSRP, L1-SINR, etc.) of the reference signal corresponding to the predicted optimal reference signal index at N time moments.

[0277] In some embodiments, the prediction result of a moment reported by the terminal can be a prediction result of a moment obtained by predicting a reference signal associated with the CSI report measured before the CSI reference resource, or a result obtained based on the prediction results of multiple moments (for example, the result obtained by time domain filtering or averaging the prediction results of multiple moments).

[0278] In some embodiments, the reference signal index information includes any of the following:

[0279] (1) The predicted optimal K reference signal indices at each of the N time moments.

[0280] For example, taking Figure 1 as an example, after measuring the reference signal at time T4, the terminal predicts the Top-K reference signals at times T5 and T6 based on the AI / ML model, and reports the Top-K reference signal index at time T5 and the Top-K reference signal index at time T6 through the first CSI report. After measuring the reference signal at time T10, the terminal predicts the Top-K reference signals at times T11 and T12 based on the AI / ML model, and reports the Top-K reference signal index at time T11 and the Top-K reference signal index at time T12 through the first CSI report.

[0281] (2) The predicted optimal K reference signal indices at some of the N moments, and the predicted optimal K reference signal indices have repeated time information. This method can reduce reporting overhead.

[0282] In some implementations, the terminal may report the prediction results of some moments in N moments where the Top-K reference signal indexes are not repeated, and not report the prediction results of other moments repeatedly, but instead indicate to the network device which moments have the same Top-K reference signal indexes (i.e., there are repetitions).

[0283] In some implementations, if the Top-K reference signal index predicted by the terminal at a certain moment is the same as the Top-K reference signal index predicted at the previous moment, it may not be reported repeatedly, and the network device may be instructed as to which moments have the same Top-K reference signal index.

[0284] For example, taking Figure 1 as an example, after measuring the reference signal at time T4, the terminal predicts the Top-K reference signals at times T5 and T6 based on the AI / ML model. If the predicted Top-K reference signals at times T5 and T6 are the same, the Top-K reference signal index at time T5 is reported through the first CSI report and the indication information [0 1] is reported. The second bit is "1" to represent that the Top-K reference signal index at the second moment is the same as the Top-K reference signal index at the first moment. Reporting "the predicted optimal K reference signal index has repeated moment information" through the indication information [0 1] here is only an example. The present disclosure does not limit the specific form of reporting "the predicted optimal K reference signal index has repeated moment information".

[0285] (3) The predicted optimal K reference signal indices at the reference time among the N time moments, and the offset information of the predicted optimal K reference signal indices at other time moments relative to the predicted optimal K reference signal indices at the reference time, where the other time moments include all other time moments among the N time moments except the reference time. This method can reduce reporting overhead.

[0286] In some implementations, the reference moment may be the first of N moments, and the terminal reports the predicted Top-K reference signal index of the reference moment. The predicted Top-K reference signal indexes of other moments are indicated by offset information.

[0287] For example, as shown in Figure 1, after measuring the reference signal at time T4, the terminal predicts the top-2 reference signals at times T5 and T6 based on the AI / ML model. The terminal reports the top-2 reference signal index at time T5 [CRI-1, CRI-2] and the offset values ​​of the top-2 reference signal index at time T6 relative to the top-2 reference signal index at time T5 [offset 1, offset 2] through the first CSI report. The network device knows from the first CSI report that the top-2 reference signal index at time T6 is [CRI-1 + offset 1, CRI-2 + offset 2].

[0288] In some embodiments, the configuration parameters of the second CSI report include one or more of the following:

[0289] Minimum reporting interval; reporting window period; number of reports within the reporting window; length of the reporting window.

[0290] Specifically, the second CSI report used to report the measurement results can be configured as non-strict periodic (quasi-periodic) reporting or periodic reporting. When configured as quasi-periodic reporting, the network device can configure relevant parameters such as the minimum reporting interval, the period of the reporting window, the number of reports within the reporting window, and the duration of the reporting window.

[0291] Among them, the minimum reporting interval refers to the minimum time interval between two CSI reports. As shown in Figure 1, the interval between the two measurements is Xms. The minimum reporting interval of the second CSI report can be configured as Xms, or as an integer multiple of Xms, such as 2*Xms. The terminal can report the average result of every two measurements.

[0292] The reporting window refers to the time period for reporting CSI reports. CSI reports are reported within the reporting window, and are not reported during the time period outside the reporting window.

[0293] For example, as shown in Figure 1, T1, T2, T3, and T4 are measurement moments, T5 and T6 are prediction moments, the measurement window period is Yms, and the network device can configure the reporting window period to be Yms; or, configure the number of reports within the reporting window to be 4, that is, report 4 CSI reports within one reporting window; or, configure the time length of the reporting window to be 4*Xms.

[0294] In the present disclosure, quasi-periodic reporting refers to periodic reporting in some time periods and no reporting in other time periods. For example, assuming that the intervals between T1′, T2′, T3′, T4′, T5′, T6′, T7′, T8′, T9′, T10′, T11′, and T12′ are all Xms, reporting is performed at T1′, T2′, T3′, and T4′, but not at T5′ and T6′, reporting is performed at T7′, T8′, T9′, and T10′, but not at T11′ and T12′. This reporting characteristic is a non-strict periodic characteristic and can be called a quasi-periodic characteristic. Of course, "quasi-periodic" can also be expressed using other words, as long as the meaning of "quasi-periodic" can be expressed. This disclosure does not limit the specific words.

[0295] In some embodiments, the method further comprises:

[0296] A time for reporting the second CSI report and / or a time for not reporting the second CSI report is determined based on the reference signal configuration associated with the second CSI report and the minimum reporting interval of the second CSI report.

[0297] For example, when the terminal determines, based on the reference signal configuration, that a certain report corresponds to measurement resources at the same time as a previous report, the terminal may not perform this report, thereby saving reporting overhead.

[0298] In some embodiments, the reporting content of the third CSI report is any one of the following:

[0299] A measurement result at one moment or a result based on measurement results at multiple moments;

[0300] The prediction result at one moment or the result obtained based on the prediction results at multiple moments.

[0301] Specifically, there are multiple different implementations for reporting the third CSI report. In one implementation, the third CSI report is periodically reported, and the content reported by the terminal each time is a measurement result or a prediction result.

[0302] For a single reported measurement result, the measurement result may be a measurement result at a single moment or a result obtained based on measurement results at multiple moments. "A result obtained based on measurement results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the measurement results at multiple moments.

[0303] For a single reported prediction result, the prediction result may be a prediction result at a single moment or a result obtained based on prediction results at multiple moments. The "result obtained based on prediction results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the prediction results at multiple moments.

[0304] For example, as shown in Figure 1, the base station configures the reporting period of the third CSI report to be Xms, and the reported content is the Top-K reference signal index or the Top-K reference signal index and L1-RSRP. When the terminal reports information at time T1 / T2 / T3 / T4, it reports the Top-K reference signal index or the Top-K reference signal index and the corresponding L1-RSRP obtained based on the measured reference signal at time T1 / T2 / T3 / T4. When the terminal reports information at time T5 / T6, it reports the Top-K reference signal index or the Top-K reference signal index obtained based on the AI / ML model and the corresponding predicted L1-RSRP.

[0305] In some embodiments, the reporting content of the third CSI report is:

[0306] A measurement result at one moment in time or a result based on measurement results at multiple moments in time; and

[0307] The prediction results at one or more moments or the results obtained based on the prediction results at multiple moments.

[0308] Specifically, in one implementation, the third CSI report is periodically reported, and the content reported by the terminal each time is a measurement result and a prediction result.

[0309] For a single reported measurement result, the measurement result may be a measurement result at a single moment or a result obtained based on measurement results at multiple moments. "A result obtained based on measurement results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the measurement results at multiple moments.

[0310] For a single reported prediction result, the prediction result may be a prediction result for one or more time periods or a result obtained based on the prediction results for multiple time periods. "A result obtained based on the prediction results for multiple time periods" may, for example, be a result obtained by time-domain filtering or averaging the prediction results for multiple time periods.

[0311] For example, as shown in Figure 2, the base station configures the reporting period of the third CSI report to be Xms. After completing the measurement at time T4, the terminal reports the Top-K reference signal index or Top-K reference signal index and the corresponding L1-RSRP at time T4, T5, and T6. The report content at time T4 is obtained based on the measured reference signal, and the report content at time T5 or T6 is obtained based on the prediction results of the AI / ML model. After completing the measurement at time T7, the beam information at time T7, T8, and T9 is reported, and so on.

[0312] In some embodiments, the reporting content of the third CSI report is any one of the following:

[0313] A measurement result at one moment or a result based on measurement results at multiple moments;

[0314] A measurement result at a moment in time or a result based on measurement results at multiple moments in time, as well as a prediction result at one or more moments in time;

[0315] A measurement result at one moment or a result based on measurement results at multiple moments, as well as a result based on prediction results at multiple moments.

[0316] Specifically, in one implementation, the third CSI report is quasi-periodic reporting, and the content reported by the terminal each time is a measurement result, or a measurement result and a prediction result.

[0317] The configuration parameters of quasi-periodic reporting include one or more of the following: minimum reporting interval, reporting window period, number of reports within the reporting window, and time length of the reporting window.

[0318] For a single reported measurement result, the measurement result may be a measurement result at a single moment or a result obtained based on measurement results at multiple moments. "A result obtained based on measurement results at multiple moments" may be, for example, a result obtained by time-domain filtering or averaging the measurement results at multiple moments.

[0319] For a single reported prediction result, the prediction result may be a prediction result for one or more time periods or a result obtained based on the prediction results for multiple time periods. "A result obtained based on the prediction results for multiple time periods" may, for example, be a result obtained by time-domain filtering or averaging the prediction results for multiple time periods.

[0320] For example, as shown in Figure 1, the base station configures the minimum reporting interval of the third CSI report to be Xms, the reporting window period to be Yms, and the number of reports within the reporting window to be 4. The terminal reports the Top-K reference signal index or Top-K reference signal index and the corresponding L1-RSRP at times T1, T2, and T3 at intervals of Xms. After completing the measurement at time T4, the terminal reports the Top-K reference signal index or Top-K reference signal index and the corresponding L1-RSRP at times T4, T5, and T6. The report content at time T4 is obtained based on the measured reference signal, and the report content at time T5 or T6 is obtained based on the prediction results of the AI / ML model. This is analogous to complete the four reports within each Yms.

[0321] In some embodiments, the method further comprises:

[0322] Send a reference signal configuration to the terminal. The reference signal configuration includes one or more of the following reference signal configuration parameters:

[0323] Minimum sending interval;

[0324] The period of the sending window;

[0325] The number of times the reference signal is sent within the sending window;

[0326] The length of the send window;

[0327] The number of times the reference signal is sent within a time window;

[0328] The number of times the reference signal is not sent within a time window;

[0329] The length of the time window.

[0330] Specifically, when AI / ML technology is used for beam prediction, the reference signal can be sent non-strictly periodically. For example, the reference signal may not be sent at the prediction moment shown in Figure 1. This non-strictly periodic time domain transmission behavior, in which the reference signal is sent periodically in some time periods and not sent in other time periods, can be referred to as quasi-periodic transmission, and the reference signal can be referred to as a quasi-periodic reference signal. Similar to the quasi-periodic reporting described above, other terms can be used to replace the expression of quasi-periodicity, and this disclosure does not limit it.

[0331] The network device can configure the terminal with relevant parameters of the quasi-periodic reference signal, such as the minimum sending interval, the period of the sending window, the number of times the reference signal is sent within the sending window, the time length of the sending window, etc.

[0332] The minimum transmission interval refers to the minimum time interval between two transmissions of a reference signal. For example, the minimum transmission interval of each reference signal in the reference signal set corresponding to SetA in FIG1 is X ms.

[0333] The transmission window refers to the time period during which a reference signal is transmitted. Reference signals are transmitted within the transmission window, and are not transmitted outside the transmission window. In some embodiments, the measurement window and the transmission window have the same time period. For example, in Figure 1 , the transmission window period is Y ms, and the number of reference signal transmissions within each transmission window is 4, or the transmission window duration is 4*X ms.

[0334] In some implementations, the network device may configure the minimum reference signal transmission interval, as well as at least one of the number of reference signal transmissions within a time window, the number of reference signal non-transmissions within a time window, and the time length of the time window, so that the terminal can learn the time domain behavior of the reference signal.

[0335] In some implementations, the time window may be the length of one period of a transmission window, where the time window includes the transmission window and the time period between two transmission windows. For example, the time period T1 to T7 shown in FIG1 may be one time window, where the reference signal is transmitted four times and not transmitted two times.

[0336] The methods provided in the various embodiments of the present disclosure are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0337] The following describes the methods provided in the above embodiments of the present disclosure through examples of specific application scenarios.

[0338] Example 1:

[0339] In this example, the base station configures reference signal set #1, which includes 8 CSI-RSs. The reference signal parameters configured by the base station include:

[0340] Minimum sending interval: 10ms;

[0341] Number of times the reference signal is sent within a time window: 2 times;

[0342] The number of times the reference signal is not sent within a time window is 2 times, or the duration of the time window is 40ms.

[0343] Figure 5 illustrates the transmission timing of Reference Signal Set #1 according to an embodiment of the present disclosure. Based on the reference signal parameters configured by the base station, a terminal can understand the time-domain behavior of the base station in transmitting reference signals, as shown in Figure 5. Specifically, the base station transmits Reference Signal Set #1 at times T1, T2, T5, T6, T9, and T10. The terminal measures the reference signals at these times based on the base station's configuration information.

[0344] Example 2:

[0345] In this example, the base station configures CSI report #1 to be associated with reference signal set #1 in Figure 5. The report contains the top-K reference signal indices of the measured reference signals and their corresponding L1-RSRPs. The CSI reporting parameters configured by the base station include:

[0346] Minimum reporting interval: 10ms;

[0347] Reporting window period: 40ms;

[0348] Number of reports within the reporting window: 2 times.

[0349] Alternatively, the base station configures the minimum reporting interval to be 10 ms, and negotiates / specifies with the terminal that if the current report and the previous report correspond to the measurement resources at the same time, the terminal does not perform the current report.

[0350] Figure 6 is one of the terminal reporting timing diagrams provided in an embodiment of the present disclosure. According to the CSI reporting parameters configured by the base station, the terminal reports the beam information according to the timing in Figure 6, reports the reference signal measurement result of time T1 in Figure 5 at time T1', reports the reference signal measurement result of time T2 at time T2', does not report at times T3' and T4', and so on.

[0351] Example 3:

[0352] In this example, the terminal reports to the base station that it can perform time-domain beam prediction based on the AI / ML model / AI function. The measurement window includes two measurement moments separated by 10ms, and the prediction window includes two prediction moments separated by 10ms. That is, the optimal beam for the next two moments is predicted based on the measurement results at the two moments. The base station configures CSI report #2 to associate with reference signal set #1 in Figure 5. The reported content is the reference signal index corresponding to the optimal beam at each of the two predicted moments. If the optimal reference signal index at a certain moment is the same as the optimal reference signal index at the previous moment, it is not reported repeatedly.

[0353] The terminal measures the reference signals at times T1 and T2 in Figure 5, and obtains the reference signal indexes corresponding to the optimal beams at times T3 and T4 based on the AI / ML model / AI function.

[0354] If the reference signal index corresponding to the optimal beam at time T3 and time T4 is CRI#1, the terminal reports CRI#1 and [0 1]. The second bit is "1", indicating that the Top-K reference signal index at the second time is the same as the Top-K reference signal index at the first time.

[0355] If the reference signal indexes corresponding to the optimal beams at time T3 and time T4 are CRI#1 and CRI#2 respectively, the terminal reports CRI#1, CRI#2 and [0 0].

[0356] Example 4:

[0357] In this example, the base station configures CSI report #2 based on the AI / ML model / AI function-related information reported by the terminal, and CSI report #2 is associated with reference signal set #1 in Figure 5 (same as Example 3). The report content is the index of the reference signal corresponding to the optimal beam at the first of the two predicted moments and the offset value of the reference signal index at the second moment relative to the reported reference signal index at the first moment.

[0358] For example, assuming that reference signal set #1 includes 8 reference signals, the index of the reference signal corresponding to the optimal beam at the first moment can be represented by 3 bits (i.e., indicating which reference signal among the 8 reference signals is optimal), and the offset value of the reference signal index corresponding to the optimal beam at the second moment relative to the reported index at the first moment is represented by 2 bits. For example:

[0359] 00 means the reference signal index offset is 0, which is the same as the optimal index at the previous moment;

[0360] 01 indicates that the reference signal index offset is 1. If the optimal reference signal index at the previous moment is the i-th, then the optimal reference signal index at this moment is the i+1-th;

[0361] 10 indicates that the reference signal index offset is -1. If the optimal reference signal index at the previous moment is the i-th, the optimal reference signal index at this moment is the i-1-th.

[0362] 11 indicates that the reference signal index offset is 2. If the optimal reference signal index at the previous moment is the i-th, then the optimal reference signal index at this moment is the i+2-th.

[0363] Example 5:

[0364] In this example, the terminal reports to the base station that it can perform time-domain beam prediction based on the AI / ML model / AI function. The measurement window length is 2 (including 2 measurement moments), the prediction window length is 2 (including 2 prediction moments), and the measurement moment period is the same as the prediction moment period. That is, the optimal beam for the next 2 moments is predicted based on the measurement results at 2 moments. The base station configures CSI report #3 associated with reference signal set #1 in Figure 5, with a reporting period of 10ms. The report content is the reference signal index corresponding to the measured or predicted optimal K beams.

[0365] Figure 7 is the second schematic diagram of terminal reporting time provided by an embodiment of the present disclosure. According to the above information, the terminal reports beam information according to the time in Figure 7, reports K reference signal indices obtained according to the measurement result of the reference signal at time T1 in Figure 5 at time T1', reports K reference signal indices obtained according to the measurement result of the reference signal at time T2 in Figure 5 at time T2', reports K reference signal indices corresponding to time T3 predicted by the AI / ML model at time T3', reports K reference signal indices corresponding to time T4 predicted by the AI / ML model at time T4', and so on.

[0366] Example 6:

[0367] In this example, the terminal reports to the base station that it can perform time-domain beamforming prediction based on the AI / ML model / AI function. The input and output of the AI / ML model / AI function are the same as those in Example 3. The base station configures CSI report #3 and associates it with reference signal set #1 in Figure 5. The minimum reporting interval is 10 ms, the reporting window period is 40 ms, and the number of reports within the reporting window is 2.

[0368] FIG8 is a third schematic diagram of terminal reporting timing according to an embodiment of the present disclosure. According to the above information, the terminal reports beam information according to the timing in FIG8.

[0369] At time T1', K reference signal indexes obtained based on the measurement results of the reference signal at time T1 in FIG5 are reported;

[0370] At time T2', the K reference signal indices obtained based on the measurement results of the reference signal at time T2 in Figure 5, the K reference signal indices corresponding to time T3 predicted by the AI / ML model, and the K reference signal indices corresponding to time T4 predicted by the AI / ML model are reported.

[0371] Report in the above manner every 40ms.

[0372] Example 7:

[0373] In this example, the terminal reports that the base station can perform time domain beam prediction based on the AI / ML model / AI function. The measurement window includes 2 measurement moments with a measurement interval of 30ms, and the prediction window includes 2 prediction moments with an interval of 10ms.

[0374] The base station configures CSI report #4 for periodic reporting based on the information reported by the terminal, and the reporting period is 30ms. Figure 9 is an example diagram of the sending time of reference signal set #2 provided in an embodiment of the present disclosure. As shown in Figure 9, the base station sends reference signal set #2 at T1, T4, T7, and T10. CSI report #4 is associated with reference signal set #2 in Figure 9, and the reporting content is the reference signal index corresponding to the optimal beam at each of the three moments, where the first moment is the reference signal index obtained based on measurement, and the second and third moments are the reference signal indexes obtained based on prediction.

[0375] Figure 10 is a fourth schematic diagram of terminal reporting timings provided by an embodiment of the present disclosure. Based on the configuration information of the base station, the terminal reports according to the timings in Figure 10 , where at time T1', the terminal reports the K reference signal indices obtained based on the reference signal measurement results at time T1 in Figure 9 , the K reference signal indices corresponding to time T2 predicted by the AI / ML model, and the K reference signal indices corresponding to time T3 predicted by the AI / ML model, and so on. That is, each report reports the result of one measurement time and the results of two prediction times.

[0376] It should be noted that, in the above examples, in addition to the reference signal index, the reporting content when reporting the measurement results and prediction results may also include the signal quality (such as L1-RSRP) of the reference signal corresponding to the reference signal index.
