Abstract:
1. A method for implementing indication of uplink transmission Timing Advance (TA) in a Time Division Duplex (TDD) system, comprising: receiving, by a User Equipment (UE), a TA command, searching, by the UE, a TA adjustment indicating table for a TA value corresponding to the TA command; wherein the TA adjustment indicating table is pre-configured in the UE, and the TA adjustment indicating table comprises a relationship between the TA command and the TA value; each item in the TA adjusting indicating table is configured the same with a Timing Advance (TA) adjusting indicating table in a Frequency Division Duplex (FDD) system; wherein the TA adjustment indicating table commonly-used by the TDD system and the FDD system adopts a uniform TA adjustment granularity delta TA, a value range of the TA is from 0 to TA adding, by the UE, the TA value corresponding to the TA command and a pre-configured TA adjusting offset in the UE to obtain a practical uplink transmission timing advance TA′; and transmitting, by the UE, uplink data according to the TA′.
