    摘要： A method of UE transmit power adjustment based on TPC command in adaptive TDD systems is proposed. A UE obtains TDD configuration information from a base station in an adaptive TDD system. The UE also obtains an HARQ reference configuration from the base station. The UE then receives a transmit power control (TPC) command in one or more previous subframes. The UE performs power adjustment in a subsequent subframe based on the TPC command. The location of the previous subframes is determined based on the HARQ reference configuration. In one embodiment, an UL HARQ reference configuration is applied for PUSCH power control. In another embodiment, a DL HARQ reference configuration is applied for PUCCH power control.

    摘要： A method of DRX operation enhancement in adaptive TDD systems is proposed. A UE configures and enters DRX operation in an LTE/LTE-A mobile communication network. The UE obtains adaptive TDD configuration information from a base station. The adaptive TDD configuration information comprises an actual TDD configuration and a reference TDD configuration. The UE performs DRX timer counting and HARQ timer counting based on the reference TDD configuration. The UE also synchronizes DRX status with the base station. With the reference TDD configuration, it can avoid the potential misunderstanding between eNB and UE regarding DRX and HARQ RTT timing when TDD configuration changes.
