[0002] In recent years, various applications of drones have attracted more and more attention, such as joint operation of multiple drones, personal entertainment applications, cargo delivery, etc. These drone applications can be realized or enhanced in business performance based on wireless technology.

[0003] LTE has been enhanced for drones in version 15 to meet their needs for data transmission and mobility.

[0004] In December 2021, at the RAN#94 plenary meeting, a work item for version 18 NR support for drone functions was proposed and approved, see non-patent document: RP-213600 New WID on NR support for UAV (Uncrewed Aerial Vehicles).

One of the goals of this work item is to enhance the measurement report based on the characteristics of drone equipment. Possible enhancements include: measurement report triggered by UE based on the configured height threshold, including information such as height, position and speed in the measurement report, flight path report, measurement report reporting based on the number of cells that meet the measurement event triggering conditions at the same time based on the configuration, etc.

[0005] Therefore, it is necessary to discuss how to initiate measurement reports of drone devices after NR supports drone functions, taking into account the altitude characteristics of drone devices, so as to reduce interference and improve performance. Summary of the invention

[0008] Preferably, when at least one of the following is satisfied, it is determined that the first conditional judgment needs to be performed: the event identifier is set as a combined measurement event; and the exit condition of the combined measurement event is satisfied within a period of time.

[0009] Preferably, the first condition includes at least one of the following: the exit condition of the combined measurement event is satisfied only due to a change in altitude; the exit condition of the combined measurement event is satisfied only due to the last exit condition of the measurement event being satisfied; and the exit condition of the combined measurement event is satisfied only due to the second exit condition of the measurement event being satisfied.

[0010] Preferably, the departure report indication is used to indicate at least one of the following information: the departure report indication is configured in a combined measurement event, and when the departure condition is satisfied only due to a change in altitude, whether the UE should initiate a measurement report procedure; and the departure report indication is configured in a combined measurement event, and when the departure condition is satisfied only due to the last departure condition of the measurement event, whether the UE should initiate a measurement report procedure.

[0011] In addition, according to the present invention, a user equipment is proposed, comprising: a processor; and a memory storing instructions, wherein the instructions execute the above method when executed by the processor.

[0012] According to the present invention, the reporting of the measurement report can be triggered correctly and timely, the abnormal situation that the measurement report cannot be reported is avoided, and the service performance of the UE in the mobile scenario is improved.

[0069] NR Measurement

[0070] The measurement model of NR is as follows Figure 1 shown.

[0071] -A: Measurement samples of a single beam inside the physical layer.

[0072] - Layer 1 filtering: The layer 1 (L1) filtering process performed within the physical layer based on single beam measurement samples.

[0073] -A 1 : The measurement result of a single beam obtained after layer 1 filtering. This result is reported from the physical layer to the RRC layer (i.e., from L1 to L3).

[0074] -Beam selection / merging: Select / merge certain measurements from the beam measurement results reported by the physical layer to obtain the measurement results of the cell.

[0075] -B: The cell measurement results are reported to the RRC layer (ie L3).

[0076] - Layer 3 cell quality filtering: Filter the cell measurement results according to filtering parameters, etc.

[0077] -C: Measurement results, used as input for evaluation of reporting criteria.

[0078] - Evaluate reporting criteria: Evaluate whether to trigger measurement report reporting based on the configuration parameters of the measurement report.

[0079] -D: Report the measurement report containing the cell measurement results to the base station on the air interface

[0080] - Layer 3 beam filtering: Layer 3 (L3) filtering is performed on the measurement results of a single beam.

[0081] -E: Measurement results of a single beam after filtering operation.

[0082] -Beam selection reporting: Select the measurement results of X beams from the measurement results of K beams obtained at point E.

[0083] -F: Report a measurement report containing beam measurement results to the base station over the air interface

[0084] In the RRC connected state, the network sends a measurement configuration (MeasConfig) to the UE through an RRC reconfiguration message, where the measurement configuration may include: measurement object configuration, measurement report configuration, measurement identifier configuration, measurement quantity configuration, measurement interval configuration, etc. The UE saves the measurement configuration in the UE's measurement configuration variable (VarMeasConfig).

[0085] Measurement objects: refers to the objects that the UE needs to measure. The network can configure the measurement object list to contain multiple measurement objects. The measurement object configuration mainly includes: the time-frequency resource location and subcarrier spacing of the reference signal used for measurement, the frequency information of the measurement, etc. The measurement object is identified by the measurement object identifier, and each measurement object corresponds to a measurement object identifier.

[0086] Reporting configurations: Each measurement object can correspond to one or more reporting configurations. The network can configure a reporting configuration list to contain multiple measurement reporting configurations. The measurement reporting configuration mainly includes: reporting criteria, measurement events, reference signal type, and reporting format. The measurement report is identified by a measurement report identifier, and each measurement report corresponds to a measurement report identifier.

[0087] Measurement identities (Measurement ID): used to associate measurement object identities (ID) and measurement report identities (ID). Each measurement identity is associated with a measurement object identity and a measurement report identity. The network can configure the measurement identity list to contain multiple measurement identities.

[0088] Quantity configurations: mainly include the configuration of measurement filter parameters.

[0089] Measurement gaps: The time period that the UE may use for measurement.

[0090] In the measurement report configuration, you can configure the type of triggered measurement report, including periodic triggered measurement report and event triggered measurement report. For event triggered measurement report, the network configures the triggering conditions of the measurement report, such as RSRP / RSRQ and time thresholds. When the conditions are met, the UE sends a measurement report to the network. After sending an event-triggered measurement report, the UE can periodically report the measurement report of the event to the base station multiple times. That is, after the UE sends a measurement report triggered by an event, it starts a periodic report timer for the measurement ID associated with the event. After the periodic report timer times out, it reports the measurement report corresponding to the measurement ID associated with the event again.

[0091] For a measurement ID, if the measurement report type (corresponding to the measurement ID) is set to event triggered eventTriggered, and for one or more cells in all cell measurement results after layer 3 filtering, the trigger entry condition (entering condition) applied to the measurement event (corresponding to the measurement ID) is satisfied within a period of time (e.g., trigger time timeToTrigger), if the cell is (or contains) the first cell that triggers the measurement event, the UE adds a measurement report entry (entry) in the measurement report list variable (VarMeasReportList) for the measurement ID, and the UE includes the cell (one or more) that triggers the measurement event, or the concerned cell, in the cell triggered list (cellsTriggeredList), and initiates the measurement report process. If the triggering event is related to a neighboring cell, such as Event A3 (the neighboring cell quality is better than SpCell and exceeds a threshold), Event A4 (the neighboring cell quality exceeds a threshold), Event A5 (SpCell is lower than threshold 1 and the neighboring cell is higher than threshold 2), etc., the cell included in cellsTriggeredList is the neighboring cell.

[0092] For a measurement ID, if the measurement report type (corresponding to the measurement ID) is set to event triggered eventTriggered, and for all cell measurement results after layer three filtering, there is one or more cells, the triggering leaving condition (leaving condition) applied to the measurement event (corresponding to the measurement ID) is met within a period of time (such as trigger time timeToTrigger), and the cell is included in the cellsTriggeredList, the UE deletes the cell from the cellsTriggeredList of the measurement ID in VarMeasReportList. If the leaving report parameter (reportOnLeave) configured by the network is set to TRUE, the UE initiates the measurement report process. If the cellsTriggeredList of the measurement ID in VarMeasReportList is empty, the UE deletes the measurement report entry of the measurement ID in VarMeasReportList, and if the periodic report timer of the measurement ID is running, the UE stops the timer.

[0093] The measurement configuration variable and the measurement report list variable are both variables inside the UE. The measurement configuration variable contains the accumulated configuration of the measurement to be performed by the UE. The measurement report list variable contains the measurement result information that meets the triggering condition.

[0094] Combined measurement events

[0095] Since the drone UE is flying in the air at a certain height above the ground, it can detect more neighboring cells than the UE on the ground, and will more frequently meet the trigger entry and trigger exit conditions of the measurement event, which may trigger measurement reports frequently. Too frequent measurement reports will waste air interface resources and consume power, and also cause interference to other UEs and networks. At the same time, for drone UEs at different altitudes, the measured signal strength / quality changes rapidly with the change of altitude. If only the signal strength / quality is considered during switching, the UE may not be able to switch to the appropriate cell, thereby affecting mobility. To solve these problems, the network can control how the UE triggers the reporting of measurement reports by configuring a combined measurement event based on altitude and signal strength / quality, that is, considering both the UE's altitude condition and the cell quality condition in the measurement event. For example, event A3H1, event A3H2, event A4H1, event A4H2, event A5H1, and event A5H2 can all be considered as combined measurement events.

[0096] For example, event A3H1 includes an entry condition related to cell quality, that is, the quality of the neighboring cell is better than that of SpCell (for example, the quality of the neighboring cell is higher than a certain threshold than SpCell, or higher than a certain threshold plus an offset value), then the first entry condition of A3H1 is considered to be met; at the same time, event A3H1 also includes an entry condition related to height, that is, the UE height is higher than a certain threshold value (or higher than a certain threshold value plus an offset value), then the second entry condition of A3H1 is considered to be met. Event A3H1 includes an exit condition related to cell quality, that is, the quality of the neighboring cell is worse than that of SpCell (for example, the quality of the neighboring cell is lower than a certain threshold than SpCell, or lower than a certain threshold minus an offset value), then the first exit condition of A3H1 is considered to be met; at the same time, event A3H1 also includes an exit condition related to height, that is, the UE height is lower than a certain threshold value (or lower than a certain threshold value minus an offset value), then the second exit condition of A3H1 is considered to be met. When both the first entry condition and the second entry condition are met, the entry condition of event A3H1 is met. When the first entry condition or the second entry condition, that is, one of the first entry condition and the second entry condition, is satisfied, the exit condition of event A3H1 is satisfied.

[0097] Similarly, other combined measurement events also include multiple entry conditions and multiple exit conditions, namely, cell quality related entry / exit conditions (also referred to as A entry / exit conditions) and height related entry / exit conditions (also referred to as H entry / exit conditions).

[0098] The network configures the combined measurement event through RRC dedicated signaling (such as RRC reconfiguration message). Through the combined measurement event, the network can obtain more appropriate neighboring cell information, thereby improving the handover performance, and can also reduce the interference caused by excessive measurement report reporting to a certain extent.

[0099] The present invention discusses a method for triggering a measurement report based on a combined measurement event configured by a network. Through the present invention, the reporting of the measurement report can be correctly and timely triggered, the abnormal situation where the measurement report cannot be triggered is avoided, and the service performance of the UE in a mobile scenario is improved.

[0119] When the UE determines that the first condition is met, the UE initiates a measurement report procedure.
