AI Technical Summary
In the existing beam reporting process, if the terminal only reports the beam measurement results, it is easy to cause random access failure or excessive delay. This is because the handover delay causes the signal quality of the currently reported beam to deteriorate in the future, or the reported beam is not the best beam for future handover.
The terminal carries the beam prediction results or the measurement results and prediction results in the measurement report, and the network-side equipment configures the random access resources of the target cell based on these results.
By carrying the prediction results of the beam, network-side devices can configure random access resources more accurately, reduce random access failures and latency, and improve handover efficiency.

[0051] In at least one embodiment of the present application, the method further comprises:
[0052] The terminal determines the prediction result of the beam according to the measurement result of the beam and an artificial intelligence (AI) function or an AI unit.

[0054] The AI function, i.e. an AI algorithm function, can include multiple AI models or AI units.
[0055] Optionally, in the case that the measurement result of the beam is the signal quality of the beam, the prediction result of the beam can be understood as the predicted signal quality of the beam in the future prediction window or at the future time point.
[0056] Further optionally, the prediction window length or the predicted future time point corresponding to the prediction result of the beam is configured by a network side device or predefined by a protocol, or the prediction window is implicitly associated with the AI model of the beam prediction.
[0057] As an optional embodiment, the terminal determines the first cell in step 201, including:
[0058] In the case that the terminal reports the measurement report triggered by the measurement event, the terminal determines the cell in the cell trigger list as the first cell;
[0059] Or,
[0060] In the case that the terminal reports the measurement report triggered by the period, the terminal determines the special cell SpCell and / or at least one available cell with the strongest signal quality as the first cell;

[0062] In a case that the terminal is triggered to report the measurement report based on a prediction result of a radio resource management (RRM) measurement or a prediction result of an event, the terminal determines a cell whose prediction result meets a preconfigured condition as the first cell.
[0063] In an optional embodiment of the present application, the step 201 of determining the first beam in the first cell comprises:
[0064] The first beam in the first cell is determined according to at least one of the measurement result of the beam in the first cell and the prediction result.
[0065] In the first implementation, the terminal determines the first beam in the first cell according to the measurement result of the beam in the first cell.
[0066] Correspondingly, the terminal infers the prediction result of the first beam in the first cell according to the measurement result of the first beam in the first cell, and reports the prediction result of the first beam in the first cell in the measurement report.
[0067] As an optional embodiment, the method further comprises:
[0068] The terminal receives first indication information from a network side device, and the first indication information is used to indicate whether the measurement result or the prediction result of the first beam is carried in the measurement report.
[0069] In this embodiment, the terminal determines the first beam in the first cell according to the measurement result of the beam, and reports the prediction result of the first beam, thereby helping the network side device to determine the future signal quality of the beam and to configure more optimal random access resources for handover.
[0070] In the second implementation, the terminal determines the first beam in the first cell according to the prediction result of the beam in the first cell.
[0071] Correspondingly, the terminal reports the prediction result of the first beam in the first cell in the measurement report.
[0072] As an optional embodiment, the method further comprises:
[0073] The terminal receives first indication information from a network side device, and the first indication information is used to indicate whether the measurement result or the prediction result of the first beam is carried in the measurement report.
[0074] Optionally, the reporting of the measurement report is triggered according to a prediction result of a radio resource management (RRM) measurement or a prediction result of an event, and the terminal reports the predicted target cell and the predicted beam in the measurement report at the same time, thereby helping the network side device to configure the random access resources of the target cell and the target cell.
[0075] In at least one embodiment of the present application, the method further comprises:
[0076] The terminal receives second indication information from the network side device, and the second indication information is used to indicate the first mode, and the first mode comprises:
[0077] According to the measurement result of the first intra-cell beam, a first beam in the first cell is determined.
[0078] Or,
[0079] According to the prediction result of the first intra-cell beam, a first beam in the first cell is determined.
[0080] For example, the network side device indicates the terminal to "determine the first beam in the first cell according to the measurement result of the first intra-cell beam" through indication information A; and the network side device indicates the terminal to "determine the first beam in the first cell according to the prediction result of the first intra-cell beam" through indication information B.
[0081] For another example, the network side device indicates the terminal to "determine the first beam in the first cell according to the measurement result of the first intra-cell beam" or "determine the first beam in the first cell according to the prediction result of the first intra-cell beam" by whether or not to send indication information C. For example, the network side device indicates the terminal to "determine the first beam in the first cell according to the measurement result of the first intra-cell beam" by sending indication information C; and the network side device indicates the terminal to "determine the first beam in the first cell according to the prediction result of the first intra-cell beam" by not sending indication information C; or the network side device indicates the terminal to "determine the first beam in the first cell according to the prediction result of the first intra-cell beam" by sending indication information C; and the network side device indicates the terminal to "determine the first beam in the first cell according to the measurement result of the first intra-cell beam" by not sending indication information C.
[0082] Optionally, the above indication information A, indication information B, and / or indication information C can be carried in the report configuration (reportConfig) sent by the network side device.
[0083] In an implementation manner, it is agreed in a protocol that when the measurement report is triggered according to the RRM measurement result or the measurement event, the terminal determines the first beam based on the measurement result of the beam; and when the measurement report is triggered according to the RRM measurement prediction result or the event prediction result, the terminal determines the first beam based on the prediction result of the beam.
[0084] As an optional embodiment, determining the first beam in the first cell according to the prediction result of the first intra-cell beam comprises:
[0085] According to the prediction result of the first intra-cell beam, a first beam in the first intra-cell is determined as:
[0086] a beam with the best prediction result in the prediction result of the first intra-cell beam;
[0087] or,
[0088] a beam with a prediction result greater than a third threshold in the prediction result of the first intra-cell beam;
[0089] wherein a total number of beams reported in a first cell is less than or equal to a third number threshold.
[0090] For example, the number of beams with a prediction result greater than a third threshold in the prediction result of the first intra-cell beam is N, if N is greater than or equal to the third number threshold, the prediction result and / or measurement result of the third number threshold of beams with the best prediction result are reported; if N is less than the third number threshold, the prediction result of N beams with the best prediction result is reported.
[0091] In an optional implementation, in a case where the prediction result of the beam contains prediction results of multiple future time instants,
[0092] According to the prediction result of the first intra-cell beam, a first beam in the first intra-cell is determined as:
[0093] a first future time instant is determined according to an indication of a network side device;
[0094] a first beam in the first intra-cell is determined according to the prediction result of the first intra-cell beam at the first future time instant.
[0095] In another optional implementation, according to the prediction result of the first intra-cell beam, a first beam in the first intra-cell is determined as:
[0096] a first beam in the first intra-cell is determined based on the prediction result of the beam at a prediction event triggering time instant. For example, a measurement report is triggered due to a prediction event satisfying, if it is predicted that the event will satisfy at T1 time instant at the current time instant, the terminal sorts based on the beam prediction result at T1 time instant, thereby determining the first beam.
[0097] In this embodiment, after the terminal determines the first cell, the first beam is determined according to the prediction result of the beam, and the prediction result of the first beam is reported to the network side device, so as to ensure that the beam referenced by the network side device when configuring the random access resource is the beam with the best future signal quality.
[0098] In a third implementation, step 201 determines the first beam in the first intra-cell, comprising:
[0099] determining a first beam set according to the measurement results of the intra-cell beams; the first beam set comprises at least one beam;
[0100] determining a second beam set according to the prediction results of the intra-cell beams; the second beam set comprises at least one beam;
[0101] determining the first beam in the first cell according to the first beam set and the second beam set.
[0102] Optionally, determining the first beam in the first cell according to the first beam set and the second beam set comprises:
[0103] determining the same beam in the first beam set and the second beam set as the first beam in the first cell.
[0104] In other words, when there is a same beam in the first beam set and the second beam set, the measurement report comprises the measurement result and / or the prediction result of the same beam. For example, the first beam set is beam 1, beam 2 and beam 3; the second beam set is beam 1, beam 2 and beam 4; only the measurement result and / or the prediction result of beam 1 and the measurement result and / or the prediction result of beam 2 are reported.
[0105] As an optional embodiment, the first beam in the first cell comprises:
[0106] the beam comprised in the first beam set;
[0107] the beam comprised in the second beam set.
[0108] Optionally, whether to report the prediction result of the beam comprised in the first beam set in the measurement report can be configured by the network side device or agreed by the protocol; or, whether to report the measurement result of the beam comprised in the second measurement report in the measurement report can be configured by the network side device or agreed by the protocol; which is not limited herein.
[0109] For example, the measurement report comprises the measurement result of the beam comprised in the first beam set and the prediction result of the beam comprised in the second beam set; optionally, the measurement report further comprises the prediction result of the beam comprised in the first beam set and / or the measurement result of the beam comprised in the second beam set.
[0110] Optionally, when there is a repeated beam in the first beam set and the second beam set, the measurement result and the prediction result of the repeated beam need to be reported, i.e. the measurement report comprises the measurement result and the prediction result of the repeated beam.
[0111] Optionally, in the case that there are same beams in the first set of beams and the second set of beams, the prediction results and / or measurement results of the same beams are not reported repeatedly in the measurement report.
[0112] For example, the first set of beams is beam 1, beam2, beam3, and the second set of beams is beam 1, beam2, beam4. Then, beam 1 and beam2 are reported only once in the current measurement report, i.e., beam 1, beam2, beam3, beam4 are reported.
[0113] Optionally, in the case that the determined number of the first beams is less than the first number threshold, and there are prediction results greater than the first threshold in the prediction results of the beams of the first cell, the measurement report further includes: the prediction results of at least one beam with the prediction results greater than the first threshold.
[0114] In at least one embodiment of the present application, the prediction results and / or measurement results of the same beams are not reported repeatedly in the measurement report, including:
[0115] The fourth beam in the second set of beams is deleted;
[0116] Or,
[0117] The fourth beam in the first set of beams is deleted.
[0118] In an implementation manner, in the case that the number of beams in the second set of beams after the fourth beam is deleted is less than the number threshold, and there are prediction results greater than the target threshold in the prediction results of the beams of the first cell, the measurement report further includes: the prediction results of at least one beam with the prediction results greater than the target threshold.
[0119] In other words, when the first beam set and the beams in the second beam set have repetitions, the same beams are not reported repeatedly, and the first beam set is preferred to be combined; if the number of beams in the second beam set after combination is less than the number threshold configured by the network side device, and there are beams greater than the first threshold in the remaining predicted beams in the second beam set, the terminal reports the remaining predicted beams greater than the first threshold until a certain number threshold is reached. For example, the first beam set is beam1, beam2, and beam3; the second beam set is beam1, beam2, and beam4; at this time, the reported beams include beam1, beam2, beam3, and beam4; assuming that the number threshold is 3, the signal quality of the predicted beams is beam1>2>4>5>6, and the signal quality of the 5 beams is greater than the first threshold; at this time, the terminal can also report two predicted beams, i.e., beam5 and beam6; that is, the finally reported beams are beam1, beam2, beam3, beam4, beam5, and beam6.
[0120] In another implementation, in the case that the number of beams in the first beam set after the fourth beam is deleted is less than a certain number threshold, and there is a measurement result greater than a target threshold in the measurement results of the beams of the first cell, the measurement report further includes: the measurement result of at least one beam with a measurement result greater than the target threshold.
[0121] In other words, when the first beam set and the beams in the second beam set have repetitions, the same beam is not reported repeatedly, and the second beam set is preferred for consolidation; if the number of beams in the first beam set after consolidation is less than the second number threshold (such as maxNrofRS-IndexesToReport) configured by the network side device, and there are still beams greater than the second threshold (such as absThreshSS-BlocksConsolidation) in the remaining measurement beams in the first beam set, the terminal reports the remaining measurement beams greater than the second threshold until a certain number threshold is reached. For example, the first beam set is beam1, beam2, and beam3; the second beam set is beam1, beam2, and beam4; then the reported beams include beam1, beam2, beam3, and beam4; assuming that maxNrofRS-IndexesToReport is 3, the signal quality ranking of the measurement beams is beam1>2>4>5>6, and the signal quality of the 5 beams is greater than absThreshSS-BlocksConsolidation; then the terminal can also report two measurement beams, i.e., beam5 and beam6; that is, the finally reported beams are beam1, beam2, beam3, beam4, beam5, and beam6.
[0122] In summary, in the embodiments of the present application, after the terminal determines the first cell to be reported in the measurement report and the first beam in the first cell, the terminal includes the prediction result of the first beam or the measurement result and the prediction result of the first beam in the reported measurement report, so that the network side device configures the random access resource of the target cell in the terminal's handover preparation process according to the prediction result of the first beam in the measurement report, thereby solving the problem that the beam measurement result reported by the terminal to the network side device does not match the actual measurement result at the time of handover, resulting in random access failure or excessive delay.
[0123] As shown in FIG. 3, the embodiments of the present application also provide a beam prediction reporting method, comprising:
[0124] Step 301: The network side device receives the measurement report corresponding to the first beam reported by the terminal, wherein the measurement report carries the prediction result of the first beam, or the measurement report carries the measurement result and the prediction result of the first beam.
[0125] In the embodiments of the present application, after determining the first cell to be reported in the measurement report and the first beam in the first cell, the terminal includes the prediction result of the first beam, or the measurement result and the prediction result of the first beam in the reported measurement report, so that the network side device configures the random access resource of the target cell in the handover preparation process of the terminal according to the prediction result of the first beam in the measurement report, thereby solving the problem that the beam measurement result reported by the terminal to the network side device does not match the measurement result at the actual handover, resulting in random access failure or too long delay.
[0126] As an optional embodiment, the method further includes:
[0127] The network side device sends first indication information to the terminal, and the first indication information is used to indicate whether the measurement result or the prediction result of the first beam is carried in the measurement report.
[0128] As another optional embodiment, the method further includes:
[0129] The network side device sends second indication information to the terminal, and the second indication information is used to indicate the first mode, and the first mode includes:
[0130] The terminal determines the first beam in the first cell according to the measurement result of the beam in the first cell.
[0131] Or,
[0132] The terminal determines the first beam in the first cell according to the prediction result of the beam in the first cell.
[0133] For example, the network side device indicates the terminal to "determine the beam to be reported in the first cell according to the measurement result of the beam in the first cell" through indication information A; and the network side device indicates the terminal to "determine the beam to be reported in the first cell according to the prediction result of the beam in the first cell" through indication information B.
[0134] For another example, the network-side device indicates the terminal to "determine the first beam in the first cell according to the measurement result of the first cell beam" or "determine the first beam in the first cell according to the prediction result of the first cell beam" by whether the indication information C is sent. For example, the network-side device sends the indication information C to indicate the terminal to "determine the first beam in the first cell according to the measurement result of the first cell beam"; does not send the indication information C to indicate the terminal to "determine the first beam in the first cell according to the prediction result of the first cell beam"; or the network-side device sends the indication information C to indicate the terminal to "determine the first beam in the first cell according to the prediction result of the first cell beam", and does not send the indication information C to indicate the terminal to "determine the first beam in the first cell according to the measurement result of the first cell beam".
[0135] Optionally, the indication information A, the indication information B, and / or the indication information C can be carried in the report configuration (reportConfig) sent by the network-side device.
[0136] In an implementation manner, it is agreed in the protocol that when the measurement report is triggered according to the RRM measurement result or the measurement event, the terminal determines the first beam based on the measurement result of the beam; and when the measurement report is triggered according to the RRM measurement prediction result or the event prediction result, the terminal determines the first beam based on the prediction result of the beam.
[0137] As an optional embodiment, the method further includes:
[0138] According to the measurement report, the terminal is configured with resources.
[0139] In summary, in the embodiments of the present application, the network-side device configures the random access resources of the target cell in the handover preparation process of the terminal according to the prediction result of the first beam in the measurement report, thereby solving the problem that the beam measurement result reported by the terminal to the network-side device does not match the measurement result at the actual handover, resulting in random access failure or too long delay.
[0140] In order to more clearly describe the beam prediction reporting method provided by the embodiments of the present application, the following examples are described.
[0141] Example 1, as shown in FIG. 4:
[0142] Step 41, the terminal determines the cell to be reported in the measurement report; the method of determining the reported cell can be one of the following:
[0143] The measurement event (for example, the event A3, A4, A5, and the like configured by the network-side device) triggers the report, and the terminal reports the cell in the cell trigger list (CellsTriggeredList);
[0144] Periodic reporting, the terminal reports the SpCell and / or at least one applicable cell with the strongest signal quality;
[0145] Event-triggered reporting based on RRM measurement prediction results or event prediction results, the terminal reports the cells whose prediction results meet the pre-configuration conditions of the network side device.
[0146] Step 42, the terminal sorts the beam measurement results in each reported cell according to the signal quality, determines the beams to be reported, for example, the terminal reports the best beam and the beam greater than the threshold (absThreshSS-BlocksConsolidation), and the total number of reported beams in each cell does not exceed the number threshold (maxNrofRS-IndexesToReport) configured by the network side device;
[0147] The terminal reports the reference signal index (RS index) of the beam; optionally, the measurement value of the L3 beam is reported when includeBeamMeasurements is configured.
[0148] Step 43, the terminal infers the prediction result of the beam; the terminal performs AI model inference on the determined reported beam in step 32 to obtain the future signal quality prediction result of the beam;
[0149] Optionally, the prediction window length or the predicted future time point is explicitly configured by the network side device or pre-defined by the protocol, or the prediction window is implicitly associated with the AI model of the beam prediction.
[0150] Step 44, the terminal reports the measurement result and / or prediction result of the beam of the cell in the measurement report.
[0151] Optionally, whether to report the prediction result of the beam can be configured by the network side device.
[0152] In this example, the terminal determines the beams to be reported in the cell according to the measured beam signal quality, and simultaneously reports the measurement signal quality and the prediction signal quality of these beams, which can help the network side device to determine the future signal quality of these beams, so as to configure more optimal random access resources for handover.
[0153] Example two, as shown in FIG. 5:
[0154] Step 51, the terminal determines the cells to be reported in the measurement report; the method of determining the reported cells can be one of the following:
[0155] Measurement event (e.g. network side device configured event A3, A4, A5, etc.) triggered reporting, the terminal reports the cells in the CellsTriggeredList;
[0156] Periodic triggered reporting, the terminal reports the SpCell and / or at least one applicable cell with the strongest signal quality;
[0157] RRM measurement prediction result or event prediction result triggered reporting, the terminal reports the cells whose prediction results meet the network side device preconfigured conditions.
[0158] Step 52, the terminal infers the beam prediction result in each reported cell;
[0159] Step 53, the terminal sorts the beams according to the prediction results, and determines the beams to be reported; for example, the terminal reports the best predicted beam, and the beams greater than the first threshold, and the total number of reported beams in each cell does not exceed the second number threshold configured by the network side device;
[0160] The prediction window length or the predicted future time point is explicitly configured by the network side device or pre-defined by the protocol, or the prediction window is implicitly associated with the AI model of beam prediction;
[0161] Optionally, when the prediction result of the beam contains multiple future time points, the network side device indicates to sort the L3 beam prediction result based on the prediction result according to which future time point;
[0162] Optionally, the terminal sorts the beam prediction result based on the prediction event triggering time point; for example, the measurement reporting in step 41 is triggered due to the prediction event meeting, if it is predicted that the event will meet at T1 time point at the current time point, the terminal sorts the beam prediction result at T1 time point;
[0163] The first threshold can reuse absThreshSS-BlocksConsolidation, or define a new threshold by the network side device.
[0164] The second number threshold can reuse maxNrofRS-IndexesToReport, or define a new threshold by the network side device.
[0165] Step 54, the terminal reports the prediction result of the beam of the cell in the measurement report.
[0166] Optionally, the terminal simultaneously reports the measurement result of the L3 beam.
[0167] Optionally, the network-side device configures whether the terminal reports actual measurement results of the predicted L3 beam.
[0168] In this example, after the terminal determines the cells to be reported, the terminal determines the beams to be reported according to the predicted results of the beams. The terminal can report the best predicted beam to the network-side device, so as to ensure that the beam whose future signal quality is the best is the best beam that the network-side device refers to when configuring random access resources.
[0169] Example Three, as shown in FIG. 6:
[0170] Step 61: The terminal determines the cells to be reported in the measurement report. The method of determining the cells to be reported can be one of the following:
[0171] Reporting triggered by a measurement event (for example, events A3, A4, A5, and the like configured by the network-side device), in which the terminal reports the cells in the cell trigger list (CellsTriggeredList);
[0172] Periodic reporting, in which the terminal reports the SpCell and / or at least one applicable cell with the strongest signal quality;
[0173] Reporting triggered by the predicted results of RRM measurement or event prediction, in which the terminal reports the cells whose predicted results meet the preconfigured conditions of the network-side device.
[0174] Step 62: The terminal sorts the measurement results of the beams in each reported cell according to the signal quality, determines a beam set 1 to be reported, for example, the terminal reports the best beam and the beams greater than the threshold (absThreshSS-BlocksConsolidation), and the total number of reported beams in each cell does not exceed the number threshold (maxNrofRS-IndexesToReport) configured by the network-side device;
[0175] The terminal reports the reference signal index (RS index) of the beam. Optionally, the measurement value of the L3 beam is reported when includeBeamMeasurements is configured.
[0176] Step 63: The terminal infers the predicted results of the beams in each reported cell.
[0177] Step 64: The terminal determines a beam set 2 to be reported according to the predicted results of the beams, for example, the terminal reports the best predicted beam and the beams greater than the first threshold, and the total number of reported beams in each cell does not exceed the second number threshold configured by the network-side device.
[0178] The prediction window length or the predicted future time point is explicitly configured by the network side device or predefined by a protocol, or the prediction window is implicitly associated with the AI model for beam prediction.
[0179] Optionally, when the prediction result of the beam contains multiple future time points, the network side device indicates to sort the L3 beam prediction result based on the prediction result according to which future time point;
[0180] Optionally, the terminal sorts the prediction result of the beam based on the predicted event triggering time point. For example, the measurement reporting in step 41 is triggered due to the satisfaction of the predicted event. If it is predicted that the event will be satisfied at T1 at the current time point, the terminal sorts the beam prediction result at T1.
[0181] The first threshold can reuse absThreshSS-BlocksConsolidation, or a new threshold defined by the network side device.
[0182] The second number threshold can reuse maxNrofRS-IndexesToReport, or a new threshold defined by the network side device.
[0183] In step 65, the terminal reports the measurement result of the beam set 1 and the prediction result of the beam set 2 of the cell in the measurement report.
[0184] Optionally, the measurement report further includes the prediction result of the beam set 1.
[0185] Optionally, the measurement report further includes the measurement result of the beam set 2.
[0186] In this example, the terminal reports at least one best measurement beam and at least one best L3 prediction beam at the same time for the network side device to refer to. When the prediction accuracy is poor, the network side device refers to the measurement beam (such as the beam set 1) to configure the random access resource. When the prediction accuracy is high, the network side device refers to the prediction beam (such as the beam set 2) to configure the random access resource.
