Abstract

The invention provides a method executed by user equipment and the user equipment. The method comprises the steps of judging whether a plurality of beam measurement report BMRs to be processed exist, judging whether events related to triggering reasons of the plurality of BMRs to be processed are identical when the plurality of BMRs to be processed exist, and if the events related to the triggering reasons of the plurality of BMRs to be processed are judged to be different, generating a media access control layer control element (MAC CE) which is sent to a base station and contains BMR report information according to a priority order set based on the triggering reasons, wherein the priority order represents the order of the BMR report information contained in the MAC CE.

Description

Method performed by user equipment and user equipment Technical Field The present invention relates to the field of wireless communication technology, and in particular, to a method performed by a user equipment and the user equipment. Background When a UE in RRC connected state moves from the coverage area of one Cell to the coverage area of another Cell, in order to ensure service continuity, the base station or the network side typically instructs the UE to perform a Cell Handover (CELL SWITCH/Cell Handover) operation. The handover in the prior art is triggered by RRC signaling, i.e. when the UE receives an RRC reconfiguration message carrying a synchronization identity (herein referred to as layer 3 handover command), it will synchronize to the target cell specified in the message. This time from the receipt of the layer 3 handover command to the completion of synchronization with the target cell is referred to as a handover delay. In the handover delay, the time for the UE to initiate random access in the target cell to obtain uplink synchronization occupies a significant proportion of the handover delay. In order to shorten the uplink synchronization time, one possible method is to configure one or more candidate cells for the UE before the base station or the network side instructs the UE to perform cell switching. The UE may make measurements of the beam (beam) of the candidate cell or cells in advance before performing the handover operation and report the measurement results, which may be abbreviated as beam measurement report (beam measurement report, BMR). The base station can instruct the UE to carry out uplink synchronization in the proper beam direction of the candidate cell based on the received BMR, thereby improving the success rate of the uplink synchronization and shortening the switching time delay. However, there are various events (events) or situations in the design that can prompt the UE to send the beam measurement report to the base station or the network side, and the size of the measurement report generated by the UE each time is limited by the uplink grant size acquired by the UE, so how to generate the corresponding measurement report and how to guarantee the transmission efficiency of the triggered beam measurement report is a problem to be solved. Disclosure of Invention In order to solve the above problems, the present invention provides a method performed by a user equipment and the user equipment. According to one aspect of the present invention, there is provided a method performed by a user equipment, including determining whether there are a plurality of beam measurement report BMRs to be processed, determining whether events associated with trigger causes of the plurality of BMRs to be processed are identical when there are a plurality of BMRs to be processed, and generating a media access control layer control element (MAC CE) including BMR report information to be transmitted to a base station according to a priority order set based on the trigger causes, the priority order representing an order of BMR report information included in the MAC CE, if it is determined that the events associated with trigger causes of the plurality of BMRs to be processed are not identical. According to another aspect of the invention there is also provided a user equipment comprising a processor and a memory storing instructions which when executed by the processor perform the method as described above. Effects of the invention According to the present invention, MR MAC CEs including BMR report information can be appropriately generated, and the transmission efficiency of the BMR report information can be improved.
