Description

Measurement reporting method and apparatus TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology. BACKGROUND

[0002] Multiple scenarios or sub-scenarios are defined in 3GPP artificial intelligence / machine learning (AI / ML) study, such as normal handover, conditional handover, L1 / L2 triggered mobility (LTM) or other scenarios. Different scenarios or sub-scenarios can correspond to one or more features / feature groups. Applying AI / ML to the above feature / feature group is called AI / ML-based / enabled feature / feature group. One AI / ML-based / enabled feature / feature group can correspond to one or more AI functionalities and / or one or more AI models. One AI functionality can correspond to one or more AI models. The function refers to the AI / ML-based / enabled feature / feature group that is configured to be enabled. The possible logic is shown in FIG. 1.

[0003] The AI model can be deployed on the terminal device. For example, the one-sided model deployed on the terminal device can be called the UE-side model. One side sub-model of the two-sided model or the multi-sided model can be deployed on the terminal device, which can be called the UE-part of two-sided models.

[0004] The AI model can be deployed on the network device. For example, the one-sided model deployed on the network device can be called the NW-side model. One side sub-model of the two-sided model or the multi-sided model can be deployed on the network device, which can be called the NW-part of two-sided models.

[0005] When the model is deployed or the model corresponding to the function is deployed, the configuration between the model and the terminal device needs to be considered. Taking the model deployed on the network device as an example, in order to use the AI function to perform the inference function related to mobility, the terminal device needs to provide the input information of the model. The possible input information can be the measurement result information (also referred to as measurement value) of the terminal device to the service and / or neighboring cell. Therefore, the embodiments of the present application mainly consider the mechanism that the terminal device sends the measurement result information required by the model running on the network device to the network device, so that the model on the network device side can perform the corresponding inference function.

[0006] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical solutions of the present application, and for the understanding of those skilled in the art. The above technical solutions cannot be considered as known to those skilled in the art just because they are described in the background section of the present application.

[0048] Embodiments of the first aspect

[0049] The embodiments of the present application provide a measurement reporting method, which is described from the side of the terminal device. In the embodiments of the present application, the AI model is deployed on the network device side, and the network device performs inference functions related to mobility management, for example, the network device can perform AI prediction on the measurement object, including at least one of prediction of measurement results, prediction of mobility-related configurations, and / or other possible AI predictions.

[0050] FIG. 2 is a schematic diagram of a measurement reporting method according to an embodiment of the present application. As shown in FIG. 2, the method includes:

[0051] 201, the terminal device receives configuration information sent by the network device; the configuration information includes first information for indicating at least one first measurement object;

[0052] 202, the terminal device performs measurement according to the configuration information;

[0053] 203, the terminal device sends a measurement report to the network device, and the measurement report includes at least two measurement values of the at least one first measurement object.

[0054] It is worth noting that the above FIG. 2 only schematically describes the embodiments of the present application, but the present application is not limited thereto. For example, some other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above description, and the description is not limited to the above FIG. 2.

[0055] According to the embodiments of the present application, the terminal device is introduced to obtain at least two measurement values of at least one first measurement object based on the configuration of the network device and report to the network device, which is used as the inference input information of the AI model on the network device side; so that the network device and the terminal device can better manage the deployed AI model, enable the corresponding prediction function, reduce the measurement overhead of the terminal device, and improve the mobile robustness of the terminal device.

[0056] In some embodiments, the network device can send configuration information to the terminal device, so that the terminal device performs measurement according to the configuration information. The configuration information can include first information, and the first information is used to indicate at least one first measurement object. The first information can include information of the at least one first measurement object, or the first information can include information of the at least one first measurement object and information of at least one second measurement object. Wherein, the first measurement object is a measurement object that needs the terminal device to report at least two measurement values. The second measurement object is a measurement object that the terminal device reports one measurement value. The measurement value can be a measurement result (also known as a measured value) obtained after the terminal device performs actual measurement. The terminal device can determine which measurement objects need to measure at least two measurement values according to the configuration information, so as to perform actual measurement according to the configuration information.

[0057] In some embodiments, the information of the measurement object includes frequency point information, or frequency point information and cell information, or frequency point information, cell information and beam information. It can be understood that the embodiments of the present application are described by taking the measurement object as an example, which can include the first measurement object and / or the second measurement object. The measurement result can be at least one corresponding measurement result of a channel state information reference signal (CSI-RS) or a synchronization signaling block (SSB) or other reference information. The possible measurement result information includes at least one of the following information: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), reference signal strength indicator (RSSI), signal to interference plus noise ratio (SINR) or other signal quality information. The measurement result can be a layer 1 (L1) measurement result and / or a layer 3 (L3) measurement result. Optionally, the first information can further include reference signal (measurement resource) configuration information, and the reference signal can be a CSI-RS and / or an SSB or the like. The reference signal configuration information is used to indicate at least one resource set information (reference signal set information). Further, the above-mentioned resource set information can be used to indicate one or more measurement resources (reference signals). As an example, the reference signal configuration information can include at least one reference signal set identifier (measurement resource set identifier) information and the identifier information of one or more measurement resources (reference signals) constituting the reference signal set (measurement resource) set. For example, taking the reference signal as the CSI-RS as an example, the reference signal configuration information can include CSI-ResourceConfigId and at least one CSI-RS-ResourceSetId. The CSI-RS-ResourceSetId can include at least one of the following information: at least one NZP-CSI-RS-ResourceSetId, at least one CSI-SSB-ResourceSetId, and at least one CSI-IM-ResourceSetId. Further, the reference signal configuration information can further include at least one NZP-CSI-RS-ResourceId, at least one CSI-SSB-ResourceId, and at least one CSI-IM-ResourceId.But here is only an example, the embodiments of the application do not take this as a limitation. The cell information includes at least one of the following information: cell global identifier (CGI), physical cell identifier (PCI) and frequency point information, cell identifier (cell ID), non-public network identifier (NPN ID), non-terrestrial network identifier (NTN ID) or other cell identifiers. The CGI can include a public land mobile network (PLMN ID) and a cell ID. Optionally, the cell information can also include tracking area code (TAC) and / or the identification information of the network device to which the cell belongs, such as global network device identifier.

[0058] As an implementation manner (one), when the first information includes the information of at least one first measurement object and the information of at least one second measurement object, the configuration information (or the first information) can further include first indication information, which is used to indicate whether at least two measurement values of the corresponding measurement object need to be reported. The first indication information can be used for the terminal device to identify the first measurement object or the second measurement object, so as to report the corresponding measurement value. The indication granularity of the first indication information can be a frequency point granularity or a cell granularity or a beam granularity, and the embodiments of the application are not limited thereto. The first indication information can be 1-bit indication information, when the bit value is 1 (or the bit value exists), it indicates that at least two measurement values of the corresponding measurement object need to be reported, or in other words, the corresponding measurement object is the first measurement object; when the bit value is 0 (or the bit value does not exist), it indicates that at least two measurement values of the corresponding measurement object do not need to be reported, or in other words, the corresponding measurement object is the second measurement object, and vice versa, and the embodiments of the application are not limited thereto.

[0059] As another implementation manner (two), the first information is used to indicate that the terminal device needs to report at least two measurement values of a first measurement object. It can be understood that in the implementation manner (two), the first information can only include information of the at least one first measurement object. For example, when the first information includes frequency point information, each cell at the frequency point needs to report at least two measurement values. When the first information includes frequency point information and cell information at the frequency point, the terminal device needs to report at least two measurement values of a cell corresponding to the cell information at the frequency point. When the first information includes frequency point information, cell information at the frequency point and beam information at the cell, the terminal device needs to report at least two measurement values of the beam at the cell at the frequency point. In the implementation manner (two), optionally, the configuration information can further include information of at least one second measurement object. The terminal device can determine whether at least two measurement values of the first measurement object need to be reported according to the information element where the first measurement object is located; and / or, the terminal device can determine whether measurement values corresponding to the second measurement object need to be reported according to the information element where the second measurement object is located.

[0060] In some embodiments, optionally, the configuration information further includes second information, and the second information is used to indicate a minimum number or a maximum number of measurement values corresponding to at least one first measurement object that need to be reported by the terminal device. The granularity of the second information can be frequency point granularity, cell granularity or beam granularity, which is not limited in the embodiments of the present application.

[0061] For example, for the implementation manner (one), the configuration information can be represented as:

[0062] And / or, the configuration information can be represented as:

[0063] For example, for the implementation manner (two), the configuration information can be represented as:

[0064] In the traditional method, the terminal device needs to perform actual measurement according to network configuration and report all measurement values of the measurement object that meet the reporting condition. In the embodiments of the present application, the terminal device can selectively perform actual measurement and report measurement values according to the configuration information. The network device predicts future measurement results based on the received measurement values, which avoids the terminal device reporting subsequent measurement values. Therefore, the measurement cost of the terminal device can be saved, such as saving energy consumption of the terminal device caused by performing actual measurement, saving signaling overhead of the terminal device caused by reporting all measurement values.

[0065] In some embodiments, the configuration information can further comprise third information and / or fourth information. The third information is used to indicate measurement time information for the terminal device to perform actual measurement, and the fourth information is used to indicate the number of measurement values corresponding to the measurement object that the terminal device needs to obtain. The third information and / or the fourth information can be applicable to at least one first measurement object and / or at least one second measurement object. Alternatively, the granularity of the third information and / or the fourth information can be a frequency point granularity, a cell granularity or a beam granularity. The third information comprises period information, or the third information comprises period information, measurement time information within the period and / or non-measurement time information within the period. The start time of the period and / or the measurement time can be an absolute time, or can be the time when the terminal device obtains the measurement value of the measurement object, or the time when the terminal device obtains the measurement value of the measurement object that satisfies the threshold.

[0066] In some embodiments, the terminal device can perform measurement on at least one measurement object according to the third information and / or the fourth information (for example, the number indicated by the fourth information can be X, X is a positive integer greater than or equal to 1). For example, the terminal device performs actual measurement on the measurement object within the time indicated by the third information, or the terminal device needs to obtain X measurement values of the measurement object, or the terminal device performs actual measurement within the time indicated by the third information and obtains X measurement values of the measurement object. The specific implementation of measurement will be described in embodiment 202.

[0067] In some embodiments, the configuration information can further comprise reporting configuration information. For example, the reporting configuration information is used to indicate the trigger condition configuration for the terminal device to report the measurement value. The terminal device can generate and send the measurement report according to the reporting configuration information. For example, the trigger condition configuration comprises reporting period information; or the trigger condition configuration comprises quality threshold information of event-triggered reporting. For example, the event can comprise any one of trigger events A1 to A6, or other trigger events, which are not limited by the embodiments of the present application. The quality threshold information is used to indicate that the terminal device reports the measurement value that satisfies the quality threshold information; or the trigger condition configuration comprises quantity threshold information of the measurement value of the measurement object that can be reported, which is used to indicate that when the number of obtained measurement values of the measurement object is greater than or equal to the quantity threshold information, the terminal device can send the measurement report. It can be understood that if the quantity threshold indicated by the trigger condition configuration is 2, the trigger condition configuration can be defaulted. That is, if the network device does not configure any reporting configuration information, when the terminal device obtains 2 measurement values of the same first measurement object, the terminal device can send the corresponding measurement report to the network device. The specific implementation of how to report the measurement report according to the reporting configuration information will be described in 203.

[0068] In some embodiments, optionally, the reporting configuration information can further include report quantity information, which is used to indicate the type of measurement result that the terminal device needs to report. The possible type of measurement result can include at least one of the following information: L1 measurement result, L3 measurement result, CSI-RS based measurement result, SSB based measurement result, RSRP, RSRQ, SINR or other information. For example, the report quantity information can be at least one of the following information: L1 / L3 CSI-RSRP / RSRQ / RSSI / SINR / other types of measurement result, or L1 / L3 SSB-RSRP / RSRQ / RSSI / SINR / other types of measurement result. Correspondingly, the terminal device needs to send the measurement result corresponding to the type of measurement result indicated by the report quantity information. This is only an example for illustration, and the embodiments of the present application are not limited thereto.

[0069] The above describes the configuration information in the embodiments of the present application. The following describes how to perform measurement and reporting according to the configuration information.

[0070] In some embodiments, in 202, the terminal device performs measurement on the measurement object according to the configuration information, and obtains the corresponding measurement value.

[0071] As an implementation manner, the configuration information includes the third information, and the third information includes the periodicity information and the measurement time information within the periodicity, and the terminal device periodically performs measurement on the measurement object within the time range indicated by the measurement time information.

[0072] For example, as shown in FIG. 3, the periodicity information and the start time of the measurement time information are absolute time, that is, when the absolute time indicated above arrives, the terminal device performs the corresponding measurement. The terminal device performs measurement on the measurement object within the time range indicated by the measurement time information. It can be understood that the measurement time information can be understood as the time when the terminal device performs measurement. That is, the measurement time information is used to indicate the longest time when the terminal device performs measurement regardless of whether the measurement object is measured. In different measurement periods, the measurement time window is fixed (the interval of the start time of the measurement time relative to the start time of the measurement period is the same in different measurement periods).

[0073] For example, as shown in FIG. 4, the start time of the period information is an absolute time, and the start time of the measurement time information is not an absolute time, but a time at which the terminal device obtains a measurement value of the measurement object. In a measurement period, the terminal device performs measurement on the measurement object, and when the terminal device measures the measurement object, the terminal device continues to perform measurement on the measurement object within the time range indicated by the measurement time information. It can be understood that the measurement time information can be understood as a time at which the terminal device performs measurement on the measured measurement object. That is, the measurement time information is used to indicate the longest time during which the terminal device continues to perform measurement on the measurement object when the terminal device measures the measurement object. In different measurement periods, the measurement time window is not fixed (the interval of the start time of the measurement time with respect to the start time of the measurement period is not the same in different measurement periods).

[0074] For example, as shown in FIG. 5, the start time of the period information and the start time of the measurement time information are not absolute times, but times at which the terminal device obtains a measurement value of the measurement object satisfying the threshold information. When the terminal device measures the measurement object and the measurement value of the measurement object obtained by the terminal device satisfies the threshold information, the terminal device starts a measurement period, and performs measurement on the measurement object within the time range indicated by the measurement time information. It can be understood that the measurement time information can be understood as a time at which the terminal device performs measurement on the measured measurement object satisfying the threshold information. That is, the measurement time information is used to indicate the longest time during which the terminal device continues to perform measurement on the measurement object when the terminal device measures the measurement object and the measurement quality of the measurement object satisfies the threshold information. Correspondingly, the start time of the period information is aligned with the start time of the measurement time information. After the end of a measurement period, the terminal device continues to measure the measurement object, and if the measurement object is not measured or the measurement value of the measured measurement object does not satisfy the threshold, the terminal device does not start a new measurement period and a measurement time window.

[0075] In another possible implementation, the configuration information can include second information and third information. The terminal device needs to obtain at least two measurement values of at least one first measurement object in one or more periods indicated by the third information, and / or report the measurement values according to the indication of the second information, and the number of reported measurement values needs to satisfy the requirement of the minimum number or the maximum number indicated by the second information. Optionally, in this implementation, the third information can further include the threshold information.

[0076] As another implementation, the configuration information includes fourth information. For example, the fourth information indicates that the terminal device needs to obtain X measurement values. The terminal device measures the measurement object, and obtains X measurement values of the measurement object according to the fourth information. Alternatively, the terminal device obtains measurement values of the measurement object satisfying the threshold information, and obtains X measurement values satisfying the threshold information according to the fourth information.

[0077] As a further implementation manner, the configuration information comprises third information and fourth information, and the terminal device acquires X measurement values of the measurement object in a time range indicated by the third information according to the third information (the implementation manner can refer to at least one of the manners shown in FIG. 3 to FIG. 5).

[0078] In some embodiments, the terminal device can record first time information corresponding to the measurement values. The first time information can be absolute time information or relative time information. As an example, when the terminal device has multiple measurement values of multiple measurement objects, the terminal device can record first time information of each measurement value, which can be absolute time information of each measurement value, or absolute time information of at least one measurement value and relative time information of other measurement values. For example, the terminal device can record absolute time information of each measurement value. For another example, the first time information can comprise absolute time information of the first measurement value recorded (which can be referred to as start time information), or absolute time information of the first measurement value of each measurement object recorded (which can be referred to as start time information). The start time information is used to indicate the time when the terminal device acquires the first measurement value, or the time when the terminal device acquires the first measurement value of the measurement object. Further, the terminal device can also record first time information (which can be referred to as acquisition time information) of each measurement value, which can be used to indicate the time offset of recording the measurement value relative to the absolute time information (start time). For another example, if the time offset is a fixed value, the fixed value is predefined or indicated by the network device, at this time, the terminal device can only record the start time information, i.e., the terminal device does not need to record the acquisition time information. In this example, the network device can determine the acquisition time information of other measurement values according to the absolute time information of the first measurement value provided by the terminal device and the fixed relative time information.

[0079] In some embodiments, the measurement values in the measurement report are sorted according to time and / or sorted according to the index of the measurement object. Optionally, the measurement report can also comprise first time information corresponding to the measurement values. If the network device can determine the first time information of the measurement values, the measurement report can also not comprise the first time information. The following examples are for illustration.

[0080] As an implementation manner, the terminal device can report the measurement values corresponding to the measurement objects in time sequence. Optionally, for the measurement values at the same time, the terminal device can further sort the measurement values according to the sizes of the measurement values or according to the measurement objects. For example, first sort in time sequence, and then sort the cells in the time according to the sizes of the measurement values or according to the measurement objects. Taking the case of first sorting in time sequence and then sorting according to the measurement objects as an example, as an example, the terminal device can determine the measurement report as: {T1|(cell 1, measurement value), (cell2, measurement value), …, (cellx, measurement value); …; Tn|(cell 1, measurement value), (cell2, measurement value), …, (cellx, measurement value)}; for example, first sort in time sequence, and then sort according to the sizes of the measurement values, the terminal device can determine the measurement report as: {T1|(cell 1, measurement value1), (cell2, measurement value2), …, (cellx, measurement valuex); …; Tn|(cell 3, measurement value3n), (cell2, measurement value2n), (cell1, measurement value1n), …, (cellx, measurement valuexn)}, where measurement value1> measurement value2> …> measurement valuex, measurement value3n> measurement value2n> measurement value1n> …> measurement valuexn; it can be understood that when the terminal device obtains the measurement values of multiple measurement result types, the sizes of the measurement values corresponding to different measurement result types can be sorted in sequence when sorting according to the sizes of the measurement values. For example, first sort according to RSRP, for example, obtain a preliminary measurement report as: {T1|(cell 1, RSRPhigh), (cell2, RSRPlow, RSRQ)} or {T1|(cell1, RSRPhigh, RSRQ), (cell2, RSRPlow, RSRQ)}; if there is no RSRP, the RSRQ can be sorted, and a further measurement report is obtained as: {T1|(cell 1, RSRPhigh, RSRQ), (cell2, RSRPlow, RSRQ), …, (cellx, RSRQhigh), (cellx-1, RSRQlow)}; if there is no RSRP and RSRQ, other measurement result types can be sorted, and the final measurement report sent to the network device is determined, and so on. It can be understood that the first time information T1~Tn is optional.

[0081] As yet another implementation manner, the terminal device can also report the corresponding measured values in the order of the measurement objects. Optionally, for multiple measurement values of the same cell, the terminal device can sort the measurement values according to the size of the measurement values or according to the time. For example, the measurement objects are sorted first, and then the measurement values of the measurement objects are sorted according to the time. As an example, the terminal device can determine the measurement report as: {(cell1, T1|measurement value, …, Tn|measurement value), …, (celln, T1|measurement value, …, Tn|measurement value)}. Optionally, for the same cell, the terminal device can sort the measurement values according to the order of the acquisition time of the measurement values, which can be sorted from old to new (as in the above example) or sorted from new to old. Alternatively, the terminal device can sort the measurement objects first, and then sort the measurement values according to the size of the measurement values. The manner of sorting the measurement values according to the size of the measurement values is described above and will not be described here. It can be understood that the first time information T1-Tn is optional to be reported.

[0082] In some embodiments, after receiving the measurement report, the network device can perform AI prediction on the measurement objects. Further, the network device can determine the target cell for handover and notify the terminal device. The implementation manner on the network device side will be described in the embodiments of the second aspect. For the terminal device, the method can further include (not shown):

[0083] The terminal device receives the handover configuration information sent by the network device, the handover configuration information being used to instruct the terminal device to perform handover to a target cell; and the terminal device performs handover to the target cell according to the handover configuration information.

[0084] In some embodiments, the handover configuration information includes at least one predicted target cell information and access configuration information and / or prediction information corresponding to the at least one target cell respectively. The access configuration information includes at least one of beam information of random access, beam quality threshold information, preamble and / or resource information of random access, or other information.

[0085] In some embodiments, the prediction information is predicted by the network device according to the measurement report and an AI model. The prediction information includes at least one of the following: time information of handover execution, effective time length information of handover execution, condition information of handover execution, information of residence in a target cell after handover, correspondence between predicted values and time of the target cell, measurement result information of the predicted target cell, and beam information of the predicted target cell. When the time indicated by the time information of handover execution arrives, the terminal device performs a handover procedure to the target cell. Alternatively, the terminal device can perform handover to the target cell within the time range indicated by the effective time length information of handover execution. The condition information of handover execution can be threshold information. When the terminal device determines that the condition information of handover execution is met, the terminal device can perform handover to the target cell. The description of the cell information is as described above and will not be repeated here. The terminal device determines the target cell that can perform handover according to the predicted target cell information. The information of residence in a target cell after handover includes residence time information, which indicates the possible residence time of the terminal device after handover to the corresponding target cell. The measurement result information of the predicted target cell can be the quality trend of the predicted target cell and / or at least one cell measurement result information of the predicted target cell. The beam information of the predicted target cell can be beam identification information, or beam identification information and beam measurement result information, etc. The description of the measurement result information is as described above and will not be repeated here. The correspondence between predicted values and time of the predicted target cell, the measurement result information of the predicted target cell, the information of residence in the target cell after handover, and the beam information of the predicted target cell can be used by the terminal device to select a target cell for handover from multiple predicted target cells.

[0086] In some embodiments, if the handover configuration information includes access configuration information and / or prediction information of a predicted target cell, the terminal device receives the handover configuration information and immediately performs a handover procedure to the target cell. If the handover configuration information includes time information of handover execution, the terminal device performs a handover procedure to the target cell when the time arrives. If the handover configuration information includes condition information of handover execution, the terminal device performs a handover procedure to the target cell when it determines that the condition is met. If the handover configuration information includes condition information of handover execution and time information of handover execution, the terminal device performs a handover procedure to the target cell when it determines that the condition is met and the time arrives. If the handover configuration information includes condition information of handover execution and effective time length information of handover execution, the terminal device performs a handover procedure to the target cell when it determines that the condition is met and is within the time range indicated by the effective time length information.

[0087] In some embodiments, if the handover configuration information includes access configuration information and / or prediction information of multiple predicted target cells, the terminal device selects a first target cell and performs handover with the first target cell. For example, the handover configuration information includes condition information corresponding to each target cell. The terminal device performs handover with a first target cell that meets the condition. Alternatively, if multiple target cells meet the handover condition, the terminal device can select a cell that is free of random access (the first target cell), or a cell that is free of contention-based random access, or a cell with the highest cell quality, or a cell with the most good beams, or a cell with the longest residence time, as the first target cell based on the prediction information (e.g., measurement result information of the predicted target cell, residence information in the target cell after handover, beam information of the predicted target cell), and performs a handover procedure with the cell.

[0088] In some embodiments, the above handover procedure can refer to related technologies, and the present application is not limited in this regard. The above configuration information and / or measurement report and / or handover configuration information can be carried by RRC signaling and / or MAC CE and / or physical layer signaling. Each piece of information in the above configuration information can be carried by the same or different signaling, and the present application is not limited in this regard.

[0089] The above embodiments only exemplarily illustrate the method of the present application, but the present application is not limited thereto. The above embodiments can be appropriately modified on the basis of the above embodiments. For example, each of the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0090] According to the embodiments of the present application, the terminal device obtains at least two measurement values of at least one first measurement object based on the configuration of the network device and reports them to the network device as inference input information of the AI model on the network device side. This enables the network device and the terminal device to better manage the deployed AI model, enables the corresponding prediction function, reduces the measurement overhead of the terminal device, and improves the mobile robustness of the terminal device.

[0091] In addition, the measurement values are used as inference input information of the AI model on the network device side. In addition, the network device can interact with the terminal device after performing inference to obtain inference output information. The terminal device selects a suitable target cell for handover based on the prediction information.
