(54) USER EQUIPMENT AND RELATED METHOD


(57) The present application provides user equipment and a related method. The method is performed by User Equipment (UE). A transmitting Packet Data Convergence Protocol (PDCP) entity is configured with packet duplication and is associated with two Radio Link Control (RLC) entities. The method comprises: receiving a packet duplication activation/deactivation Medium Access Control (MAC) Control Element (CE); and discarding, by the transmitting PDCP entity, a PDCP Protocol Data Unit (PDU) having been submitted to either of the associated RLC entities. The method can reduce the volume of data required to be transmitted, thereby conserving communication resources and improving communication efficiency and communication speed.
