Method and apparatus for implementing indication of uplink transmission timing advance

摘要

In one embodiment, a UE receives a TA command, searches 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 as a timing advance adjusting indicating table in a Frequency Division Duplex FDD system. The UE adds the TA value corresponding to the TA command and a pre-configured TA adjusting offset to obtain a practical uplink transmission timing advance TA', and transmits uplink data according to the TA'.
