ABSTRACT:
A method of controlling timing for an uplink synchronous transmission scheme is disclosed, including combining time alignment bit (TAB) information transmitted received during a predetermined period, determining a timing renewal value based on the combination, and controlling the transmission timing according to the timing renewal value. Thus, the TAB information transmitted by a base station may be used to synchronize the uplink transmissions of mobile communication devices.
