Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a beam prediction and reporting method, apparatus, terminal, and network-side equipment. Background Technology

[0002] Artificial Intelligence (AI)-based mobility enhancements include: Radio Resource Management (RRM) measurement prediction, measurement event prediction, and RadioLink Failure (RLF) or Handover Failure (HOF) prediction. RRM measurement prediction includes predictions where the direct or indirect output is a cell-level measurement prediction and a beam-level measurement prediction. Beam-level measurement prediction includes predictions where the direct or indirect output is an L3-filtered beam-level prediction.

[0003] When the network-side device configures the terminal to report the measurement results after Layer 3 filtering, the terminal reports the beam measurement results within the cell. This is used by the network-side device to configure the random access channel resources of the target cell during the handover preparation process. In the existing beam reporting process, the terminal sorts and reports the beams based on the currently measured beams. However, due to handover delays, the signal quality of the currently reported beams may deteriorate in the future, or the reported beams may not be the best beams for future handovers, leading to random access failures or excessively long handover delays in the target cell. Summary of the Invention

[0042] The beam prediction and reporting method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0043] like Figure 2 As shown in the embodiments of this application, a beam prediction reporting method is also provided, including:

[0044] Step 201: The terminal determines the first cell and the first beam within the first cell;

[0045] Step 202: The terminal reports a measurement report corresponding to the first beam. The measurement report carries either the prediction result of the first beam or the measurement result and prediction result of the first beam.

[0046] Optionally, the beam prediction result can be the beam prediction result after layer 3 filtering.

[0047] Optionally, the beam measurement results can be the beam measurement results after layer 3 filtering.

[0048] In this embodiment, after the terminal determines the first cell to be reported in the measurement report and the first beam within the first cell, the reported measurement report includes the prediction result of the first beam, or the measurement result and prediction result of the first beam. This allows the network-side device to configure the random access resources of the target cell during the terminal's handover preparation process based on the prediction result of the first beam in the measurement report. This solves the problem that the beam measurement result reported by the terminal to the network-side device does not match the actual handover measurement result, leading to random access failure or excessive delay.

[0049] In at least one embodiment of this application, the method further includes:

[0050] The terminal determines the beam prediction result based on the beam measurement results and the artificial intelligence (AI) function or AI unit.

[0051] It should be noted that the AI ​​unit described in this application embodiment may be referred to as an AI model, ML (machine learning) model, ML unit, AI structure, AI function, AI characteristic, machine learning model, neural network, neural network function, neural network functionality, etc. Alternatively, the AI ​​unit may refer to a processing unit capable of implementing specific algorithms, formulas, processing flows, capabilities, etc., related to AI. Or, the AI ​​unit may be a processing method, algorithm, function, module, or unit for a specific dataset. Alternatively, the AI ​​unit may be a processing method, algorithm, function, module, or unit running on AI / ML related hardware such as a GPU, NPU, TPU, or ASIC. This application does not impose specific limitations in this regard. Optionally, the specific dataset includes the input and / or output of the AI ​​unit.

[0052] An AI function is an AI algorithm function that may include multiple AI models or AI units.

[0053] Optionally, when the beam measurement result is the beam signal quality, the beam prediction result can be understood as: the signal quality of the beam predicted within the future prediction window or at a future point in time.

[0054] Further optionally, the prediction window length or predicted future time point corresponding to the beam prediction result is configured by the network-side device or predefined by the protocol, or the prediction window is implicitly associated with the AI ​​model of beam prediction.

[0055] As an optional embodiment, the terminal determining the first cell in step 201 includes:

[0056] When a measurement event triggers the terminal to report a measurement report, the terminal determines that the cell in the cell trigger list is the first cell;

[0057] or,

[0058] When the terminal periodically triggers the reporting of measurement reports, the terminal determines the special cell SpCell and / or at least one available cell with the strongest signal quality as the first cell;

[0059] or,

[0060] When a terminal reports a measurement report triggered by a prediction result based on Radio Resource Management (RRM) measurements or an event, the terminal determines the cell whose prediction result meets the pre-configured conditions as the first cell.

[0061] In an optional embodiment of this application, step 201, determining the first beam within the first cell, includes:

[0062] The first beam in the first cell is determined based on at least one of the measurement results of the beam in the first cell and the prediction results.

[0063] In the first implementation, the terminal determines the first beam in the first cell based on the measurement results of the beam in the first cell.

[0064] Accordingly, the terminal infers the prediction result of the first beam in the first cell based on the measurement result of the first beam in the first cell; the terminal reports the prediction result of the first beam in the first cell in the measurement report.

[0065] As an optional embodiment, the method further includes:

[0066] The terminal receives first indication information from the network-side device. The first indication information is used to indicate whether the measurement report carries the measurement result or prediction result of the first beam.

[0067] In this embodiment, the terminal determines the first beam in the first cell based on the beam measurement results and reports the prediction results of these first beams, thereby helping the network-side equipment to determine the future signal quality of these beams in order to configure better random access resources for handover.

[0068] In the second implementation, the terminal determines the first beam in the first cell based on the prediction result of the beam in the first cell.

[0069] Accordingly, the terminal reports the prediction result of the first beam in the first cell in the measurement report.

[0070] As an optional embodiment, the method further includes:

[0071] The terminal receives first indication information from the network-side device. The first indication information is used to indicate whether the measurement report carries the measurement result or prediction result of the first beam.

[0072] Optionally, the measurement report is triggered based on the RRM measurement prediction result or event prediction result. The terminal simultaneously reports the predicted target cell and the predicted beam in the reported measurement report to help the network-side equipment configure the target cell and the random access resources of the target cell.

[0073] In at least one embodiment of this application, the method further includes:

[0074] The terminal receives second indication information from the network-side device. The second indication information is used to indicate a first method, which includes:

[0075] Based on the measurement results of the beams in the first cell, the first beam in the first cell is determined;

[0076] or,

[0077] Based on the prediction results of the beams in the first cell, the first beam in the first cell is determined.

[0078] For example, the network-side device instructs the terminal to "determine the beam to be reported in the first cell based on the measurement results of the beam in the first cell" through instruction information A; the network-side device instructs the terminal to "determine the beam to be reported in the first cell based on the prediction results of the beam in the first cell" through instruction information B.

[0079] For example, the network-side device can instruct the terminal to "determine the first beam in the first cell based on the measurement results of the beam in the first cell" or "determine the first beam in the first cell based on the prediction results of the beam in the first cell" by sending indication information C. If indication information C is sent, the terminal is instructed to "determine the first beam in the first cell based on the measurement results of the beam in the first cell"; if indication information C is not sent, the terminal is instructed to "determine the first beam in the first cell based on the prediction results of the beam in the first cell"; or, if indication information C is sent, the terminal is instructed to "determine the first beam in the first cell based on the prediction results of the beam in the first cell"; if indication information C is not sent, the terminal is instructed to "determine the first beam in the first cell based on the measurement results of the beam in the first cell".

[0080] Optionally, the aforementioned indication information A, indication information B, and / or indication information C can be carried in the reporting configuration (reportConfig) sent by the network-side device.

[0081] In one implementation, the protocol stipulates that when the measurement report is triggered by RRM measurement results or a measurement event, the terminal determines the first beam based on the beam measurement results; when the measurement report is triggered by RRM measurement prediction results or event prediction results, the terminal determines the first beam based on the beam prediction results.

[0082] As an optional embodiment, determining the first beam within the first cell based on the prediction result of the beam within the first cell includes:

[0083] Based on the prediction results of the beam within the first cell, the first beam within the first cell is determined to be:

[0084] The beam with the best prediction result among the beam prediction results in the first cell;

[0085] or,

[0086] The beams in the first cell whose prediction results are greater than the third threshold;

[0087] Among them, the total number of beams reported in a first cell is less than or equal to the third number threshold.

[0088] For example, if the number of beams with prediction results greater than the third threshold in the prediction results of the first cell is N, and N is greater than or equal to the third threshold, the prediction results and / or measurement results of the third threshold beams with the best prediction results are reported; if N is less than the third threshold, the prediction results of the N beams with the best prediction results are reported.

[0089] In one optional implementation, when the beam prediction result includes prediction results for multiple future times,

[0090] The step of determining the first beam within the first cell based on the prediction result of the beam within the first cell includes:

[0091] The first future moment is determined according to the instructions of the network-side equipment;

[0092] The first beam in the first cell is determined based on the prediction result of the beam in the first cell at the first future time.

[0093] In another optional implementation, determining the first beam within the first cell based on the prediction result of the beam within the first cell includes:

[0094] Based on the beam prediction results at the predicted event trigger time, the first beam in the first cell is determined. For example, if the measurement report is triggered by the fulfillment of a predicted event, and it is predicted at the current time that the event will be fulfilled at time T1, the terminal sorts the beams based on the beam prediction results at time T1 to determine the first beam.

[0095] In this embodiment, after the terminal determines the first cell, it determines the first beam based on the beam prediction result and reports the prediction result of the first beam to the network-side device to ensure that the beam referenced by the network-side device when configuring random access resources is the beam with the best future signal quality.

[0096] In the third implementation, step 201, determining the first beam within the first cell, includes:

[0097] Based on the measurement results of the beams within the first cell, a first beam set is determined; the first beam set includes at least one beam.

[0098] Based on the prediction results of the beams in the first cell, a second beam set is determined; the second beam set includes at least one beam.

[0099] The first beam within the first cell is determined based on the first beam set and the second beam set.

[0100] Optionally, determining the first beam within the first cell based on the first beam set and the second beam set includes:

[0101] The same beams in the first beam set and the second beam set are identified as the first beams in the first cell.

[0102] In other words, if the beams in the first beam set and the beams in the second beam set are the same, the measurement report includes: the measurement results and / or prediction results of the same beam. For example, if the first beam set is beam 1, beam 2, and beam 3; and the second beam set is beam 1, beam 2, and beam 4, then only the measurement results and / or prediction results of beam 1 and beam 2 are reported.

[0103] As an optional embodiment, the first beam within the first cell includes:

[0104] The beams contained in the first beam set;

[0105] The beams contained in the second beam set.

[0106] Optionally, whether the measurement report includes the prediction results of the beams included in the first beam set can be configured by the network-side equipment or agreed upon by the protocol; or, whether the measurement report includes the measurement results of the beams included in the second measurement report can be configured by the network-side equipment or agreed upon by the protocol; no specific limitation is made here.

[0107] For example, the measurement report includes: measurement results of the beams included in the first beam set, and prediction results of the beams included in the second beam set; optionally, the measurement report also includes: prediction results of the beams included in the first beam set, and / or, measurement results of the beams included in the second beam set.

[0108] Optionally, when there is a duplicate beam between the beams in the first beam set and the beams in the second beam set, both the measurement results and prediction results of the duplicate beam need to be reported, that is, the measurement report includes the measurement results and prediction results of the duplicate beam.

[0109] Optionally, if the beams in the first beam set and the beams in the second beam set are the same, the prediction results and / or measurement results of the same beam will not be reported repeatedly in the measurement report.

[0110] For example, if the first beam set is beam 1, beam 2, beam 3; and the second beam set is beam 1, beam 2, beam 4, then beam 1 and beam 2 will only be reported once in this measurement report, that is, beam 1, beam 2, beam 3, beam 4 will be reported.

[0111] Optionally, if the number of the first beams is less than a first number threshold, and there is a prediction result greater than the first threshold among the prediction results of the beams in the first cell, the measurement report may further include: the prediction result of at least one beam whose prediction result is greater than the first threshold.

[0112] In at least one embodiment of this application, the measurement report does not repeatedly report the prediction results and / or measurement results of the same beam, including:

[0113] Delete the fourth beam from the second beam set;

[0114] or,

[0115] Delete the fourth beam from the first beam set.

[0116] In one implementation, if the sum of the number of beams in the second beam set after deleting the fourth beam and the number of beams in the first beam set is less than a certain threshold, and there is a prediction result in the prediction result of the beams in the first cell that is greater than the target threshold, the measurement report further includes: the prediction result of at least one beam whose prediction result is greater than the target threshold.

[0117] In other words, when there is overlap between the beams in the first beam set and the second beam set, the beams that are reported repeatedly are merged with priority given to the first beam set. If, after merging, the number of beams in the second beam set is less than the number threshold configured by the network-side device, and there are still beams in the remaining predicted beams in the second beam set that are greater than the first threshold, the terminal reports the remaining predicted beams that are greater than the first threshold until a certain number threshold is reached. For example, if the first beam set is beam1, beam2, and beam3, and the second beam set is beam1, beam2, and beam4, then the reported beams include beam1, beam2, beam3, and beam4. Assuming the threshold for this number is 3, the signal quality ranking of the predicted beams is beam1>2>4>5>6, and the signal quality of all 5 beams is greater than the first threshold, then the terminal can still report two more predicted beams, namely beam5 and 6. That is, the final reported beams are beam1, beam2, beam3, beam4, beam5, and beam6.

[0118] In another implementation, if the sum of the number of beams in the first beam set after deleting the fourth beam and the number of beams in the second beam set is less than a certain threshold, and there is a measurement result in the first cell's beam measurement result that is greater than the target threshold, the measurement report shall also include: the measurement result of at least one beam whose measurement result is greater than the target threshold.

[0119] In other words, when beams in the first beam set and the second beam set overlap, the same beams are not reported repeatedly, and the second beam set is merged first. If, after merging, the number of beams in the first beam set is less than the second number threshold configured by the network-side device (e.g., maxNrofRS-IndexesToReport), and there are still beams in the remaining measurement beams in the first beam set that are greater than the second threshold (e.g., absThreshSS-BlocksConsolidation), the terminal reports the remaining measurement beams that are greater than the second threshold until a certain number threshold is reached. For example, if the first beam set is beam1, beam2, and beam3, and the second beam set is beam1, beam2, and beam4, then the reported beams include beam1, beam2, beam3, and beam4. Assuming maxNrofRS-IndexesToReport is 3, the signal quality ranking of the measured beams is beam1>2>4>5>6, and the signal quality of all 5 beams is greater than absThreshSS-BlocksConsolidation, then the terminal can also report two more measured beams, namely beam5 and beam6. That is, the final reported beams are beam1, beam2, beam3, beam4, beam5, and beam6.

[0120] In summary, in this embodiment, after the terminal determines the first cell to be reported in the measurement report and the first beam within the first cell, the reported measurement report includes the prediction result of the first beam, or the measurement result and prediction result of the first beam. This enables the network-side device to configure the random access resources of the target cell during the terminal's handover preparation process based on the prediction result of the first beam in the measurement report. This solves the problem of mismatch between the beam measurement result reported by the terminal to the network-side device and the actual handover measurement result, which leads to random access failure or excessive delay.

[0121] like Figure 3 As shown in the embodiments of this application, a beam prediction reporting method is also provided, including:

[0122] Step 301: The network-side device receives a measurement report corresponding to the first beam reported by the terminal. The measurement report carries either the prediction result of the first beam or the measurement result and prediction result of the first beam.

[0123] In this embodiment, after the terminal determines the first cell to be reported in the measurement report and the first beam in the first cell, the reported measurement report includes the prediction result of the first beam, or the measurement result and prediction result of the first beam. This enables the network-side device to configure the random access resources of the target cell during the terminal's handover preparation process based on the prediction result of the first beam in the measurement report. This solves the problem that the beam measurement result reported by the terminal to the network-side device does not match the actual handover measurement result, resulting in random access failure or excessive delay.

[0124] As an optional embodiment, the method further includes:

[0125] The network-side device sends a first indication message to the terminal, the first indication message being used to indicate whether the measurement report carries the measurement result or prediction result of the first beam.

[0126] As another optional embodiment, the method further includes:

[0127] The network-side device sends a second indication information to the terminal, the second indication information indicating a first method, the first method including:

[0128] The terminal determines the first beam in the first cell based on the measurement results of the beam in the first cell;

[0129] or,

[0130] The terminal determines the first beam in the first cell based on the prediction result of the beam in the first cell.

[0131] For example, the network-side device instructs the terminal to "determine the beam to be reported in the first cell based on the measurement results of the beam in the first cell" through instruction information A; the network-side device instructs the terminal to "determine the beam to be reported in the first cell based on the prediction results of the beam in the first cell" through instruction information B.

[0132] For example, the network-side device can instruct the terminal to "determine the first beam in the first cell based on the measurement results of the beam in the first cell" or "determine the first beam in the first cell based on the prediction results of the beam in the first cell" by sending indication information C. If indication information C is sent, the terminal is instructed to "determine the first beam in the first cell based on the measurement results of the beam in the first cell"; if indication information C is not sent, the terminal is instructed to "determine the first beam in the first cell based on the prediction results of the beam in the first cell"; or, if indication information C is sent, the terminal is instructed to "determine the first beam in the first cell based on the prediction results of the beam in the first cell"; if indication information C is not sent, the terminal is instructed to "determine the first beam in the first cell based on the measurement results of the beam in the first cell".

[0133] Optionally, the aforementioned indication information A, indication information B, and / or indication information C can be carried in the reporting configuration (reportConfig) sent by the network-side device.

[0134] In one implementation, the protocol stipulates that when the measurement report is triggered by RRM measurement results or a measurement event, the terminal determines the first beam based on the beam measurement results; when the measurement report is triggered by RRM measurement prediction results or event prediction results, the terminal determines the first beam based on the beam prediction results.

[0135] As an optional embodiment, the method further includes:

[0136] Based on the measurement report, resource configuration is performed for the terminal.

[0137] In summary, in this embodiment of the application, the network-side device configures the random access resources of the target cell during the handover preparation process of the terminal based on the prediction results of the first beam in the measurement report, thereby solving the problem that the beam measurement results reported by the terminal to the network-side device do not match the actual handover measurement results, resulting in random access failure or excessive delay.

[0138] To more clearly describe the beam prediction reporting method provided in the embodiments of this application, several examples are given below.

[0139] Example 1, such as Figure 4 As shown:

[0140] Step 41: The terminal determines the cell to be reported in the measurement report; the method for determining the reporting cell may be one of the following:

[0141] Reporting triggered by measurement events (such as events A3, A4, A5, etc. configured by network-side devices), the terminal reports the cells in the CellsTriggeredList;

[0142] Periodically triggered reporting involves the terminal reporting the SpCell and / or at least one available cell with the strongest signal quality.

[0143] Reports triggered by RRM measurement prediction results or event prediction results are submitted by the terminal, which reports cells whose prediction results meet the pre-configuration conditions of the network-side equipment.

[0144] Step 42: The terminal sorts the beam measurement results in each reporting cell according to signal quality and determines the beams to be reported. For example, the terminal reports the best beam and the beams that are greater than the threshold (absThreshSS-BlocksConsolidation). The total number of beams reported in each cell does not exceed the number threshold (maxNrofRS-IndexesToReport) configured by the network side equipment.

[0145] The terminal reports the RS index (reference signal index) of the beam; optionally, if includeBeamMeasurements is configured, the terminal reports the measurement value of the L3 beam.

[0146] Step 43: The terminal infers the prediction result of the beam; the terminal performs AI model inference on the beam determined and reported in step 32 to obtain the future signal quality prediction result of the beam.

[0147] Optionally, the prediction window length or the predicted future time point is explicitly configured by the network-side device or predefined by the protocol, or the prediction window is implicitly associated with the AI ​​model for beam prediction.

[0148] Step 44: The terminal simultaneously reports the measurement results and / or prediction results of the beam of the cell in the measurement report.

[0149] Optionally, whether to report beam prediction results can be configured by the network-side device.

[0150] In this example, the terminal determines the beams to be reported within the cell based on the measured beam signal quality, and simultaneously reports the measured and predicted signal quality of these beams. This helps network-side devices determine the future signal quality of these beams in order to configure better random access resources for handover.

[0151] Example 2, such as Figure 5 As shown:

[0152] Step 51: The terminal determines the cell to be reported in the measurement report; the method for determining the reporting cell may be one of the following:

[0153] Reporting triggered by measurement events (such as events A3, A4, A5, etc. configured by network-side devices), the terminal reports the cells in the CellsTriggeredList;

[0154] Periodically triggered reporting involves the terminal reporting the SpCell and / or at least one available cell with the strongest signal quality.

[0155] Reports triggered by RRM measurement prediction results or event prediction results are submitted by the terminal, which reports cells whose prediction results meet the pre-configuration conditions of the network-side equipment.

[0156] Step 52: The terminal infers the beam prediction results for each reporting cell;

[0157] 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 beams reported in each cell does not exceed the second number threshold configured by the network side equipment.

[0158] The prediction window length or the predicted future time point is explicitly configured by the network-side device or predefined by the protocol, or the prediction window is implicitly associated with the AI ​​model of beam prediction;

[0159] Optionally, when the beam prediction results include multiple future moments, the network-side device indicates the order of L3 beam prediction results based on which future moment's prediction results are used;

[0160] Optionally, the terminal sorts the beam based on the prediction results at the time the predicted event is triggered. For example, the measurement reporting in step 41 is triggered because the predicted event is met. If it is predicted at the current time that the event will be met at time T1, the terminal sorts the beam based on the prediction results at time T1.

[0161] The first threshold can reuse absThreshSS-BlocksConsolidation, or a new threshold can be defined by the network-side device.

[0162] The second quantity threshold can be reused from maxNrofRS-IndexesToReport, or a new threshold can be defined by the network-side device.

[0163] Step 54: The terminal reports the prediction result of the beam of the cell in the measurement report.

[0164] Optionally, the terminal may simultaneously report the measurement results of the L3 beam.

[0165] Optionally, the network-side device may configure the terminal to report the actual measurement results of the predicted L3 beam.

[0166] In this example, after the terminal determines the cell to report, it sorts the beams according to the prediction results and determines the beams to report. The best predicted beam can be reported to the network-side device to ensure that the network-side device uses the best beam with the best future signal quality when configuring random access resources.

[0167] Example 3, such as Figure 6 As shown:

[0168] Step 61: The terminal determines the cell to be reported in the measurement report; the method for determining the reporting cell may be one of the following:

[0169] Reporting triggered by measurement events (such as events A3, A4, A5, etc. configured by network-side devices), the terminal reports the cells in the CellsTriggeredList;

[0170] Periodically triggered reporting involves the terminal reporting the SpCell and / or at least one available cell with the strongest signal quality.

[0171] Reports triggered by RRM measurement prediction results or event prediction results are submitted by the terminal, which reports cells whose prediction results meet the pre-configuration conditions of the network-side equipment.

[0172] Step 62: The terminal sorts the beam measurement results in each reported cell according to signal quality and determines the beam set 1 to be reported. For example, the terminal reports the best beam and the beams that are greater than the threshold (absThreshSS-BlocksConsolidation). The total number of beams reported in each cell does not exceed the number threshold (maxNrofRS-IndexesToReport) configured by the network side equipment.

[0173] The terminal reports the RS index (reference signal index) of the beam; optionally, if includeBeamMeasurements is configured, the terminal reports the measurement value of the L3 beam.

[0174] Step 63: The terminal infers the beam prediction results for each reporting cell;

[0175] Step 64: The terminal sorts the beams according to their prediction results and determines the set of beams to be reported 2. For example, the terminal reports the best predicted beam and the beams that are greater than the first threshold. The total number of beams reported in each cell does not exceed the second number threshold configured by the network side equipment.

[0176] The prediction window length or the predicted future time point is explicitly configured by the network-side device or predefined by the protocol, or the prediction window is implicitly associated with the AI ​​model of beam prediction;

[0177] Optionally, when the beam prediction results include multiple future moments, the network-side device indicates the order of L3 beam prediction results based on which future moment's prediction results are used;

[0178] Optionally, the terminal sorts the beam based on the prediction results at the time the predicted event is triggered. For example, the measurement reporting in step 41 is triggered because the predicted event is met. If it is predicted at the current time that the event will be met at time T1, the terminal sorts the beam based on the prediction results at time T1.

[0179] The first threshold can reuse absThreshSS-BlocksConsolidation, or a new threshold can be defined by the network-side device.

[0180] The second quantity threshold can be reused from maxNrofRS-IndexesToReport, or a new threshold can be defined by the network-side device.

[0181] Step 65: The terminal reports the measurement results of beam set 1 and the prediction results of beam set 2 of the cell in the measurement report;

[0182] Optionally, the measurement report may also include the prediction results for beam set 1;

[0183] Optionally, the measurement report may also include the measurement results of beam set 2.

[0184] In this example, the terminal simultaneously reports at least one best measurement beam and at least one best L3 prediction beam for reference by the network-side device. When the prediction accuracy is poor, the network-side device refers to the measurement beam (such as beam set 1) for random access resource configuration, and when the prediction accuracy is high, the network-side device refers to the prediction beam (such as beam set 2) for random access resource configuration.

[0185] The beam prediction reporting method provided in this application can be executed by a beam prediction reporting device. This application uses the example of a beam prediction reporting device executing the beam prediction reporting method to illustrate the beam prediction reporting device provided in this application.

This enables the network-side device to configure the random access resources of the target cell during the terminal's handover preparation process based on the prediction result of the first beam in the measurement report. This solves the problem that the beam measurement result reported by the terminal to the network-side device does not match the measurement result during the actual handover, resulting in random access failure or excessive delay.
