DRX AND HARQ OPERATIONS IN ADAPTIVE TDD SYSTEMS

摘要

A method of DRX and HARQ operation enhancement in adaptive TDD systems is proposed. A UE establishes a radio resource control (RRC) connection with a base station in a mobile communication network. The UE obtains adaptive time division duplex (TDD) configuration information from the base station, wherein the adaptive TDD configuration information comprises an actual TDD configuration and/or a reference TDD configuration. The UE performs a Hybrid Automatic Repeat Request (HARQ) round trip time (RTT) timer counting for each downlink (DL) HARQ process based on the adaptive TDD configuration information. The UE can avoid the potential misunderstanding between eNB and UE regarding HARQ RTT timing when TDD configuration changes.
