Abstract

A method for enhancing power saving performance of user equipment (UE) is provided. The method includes the following steps: a UE receives the downlink data transmitted by an evolved node B (eNB); the UE starts a corresponding RTT Timer according to the received downlink data, the timing of the RTT Timer is determined based on the uplink/downlink (UL/DL) configuration and the sub-frame number of the downlink sub-frame carrying the downlink data by the UE; and the UE controls the discontinuous reception (DRX) process according to the RTT Timer. By re-defining the RTT Timer, the present invention can improve power saving performance of the UE in TDD system effectively.
