METHOD AND APPRATUS FOR OPERATING MULTIPLE TIMING ADVANCE GROUP IN MOBILE COMMUNICATION SYSTEM USING CARRIER AGGREGATION

摘要

PURPOSE: A method and an apparatus for operating a plurality of timing advance groups in a wireless communication system are provided to dynamically select an uplink MCS table index in consideration of the number of uses and the amount of uplink resource use. CONSTITUTION: A controller(1109) groups a plurality of carrier waves into TAG(Timing Advance Group) according to a predetermined standard. The controller allocates a TAG index to each TAG. The controller transmits the TAG index information to a terminal. The controller generates a TAC(Timing Advance Command). The controller transmits the TAG to the terminal in random access.
