APPARATUS AND METHOD FOR TRANSCEIVING INFORMATION ON AN UPLINK TIMING GROUP IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method for transmitting information on an uplink timing group includes performing RACH procedures with user equipment for a preset period of time to generate an uplink timing group, and transmitting, to the user equipment, a message including information on the configuration of the thus-generated uplink timing group, wherein said uplink timing group is a group of one or more component carriers to which identical uplink timing correction is applied.
