USER EQUIPMENT AND RELATED METHOD

WIPO Patent Application WO/2019/134529

A1

The present application provides a user equipment and a related method. The method is a method performed by a user equipment (UE). A packet data convergence protocol (PDCP) sending entity is configured with packet repetition, and is associated with two radio link control (RLC) entities. The method comprises: receiving a packet repetition activation/deactivation media access control (MAC) control element (CE); and the PDCP sending entity deleting a PDCP protocol data unit (PDU) that has been submitted to any one of the associated RLC entities. According to the method, the amount of data that needs to be transmitted can be reduced, thereby saving on communication resources and improving a communication efficiency and a communication speed.
