ABSTRACT:
A method is provided for transmitting control information by a Base Station (BS) in a Time Division Duplexing (TDD)-based Orthogonal Frequency Division Multiple Access (OFDMA) system. The method includes determining a TDD ratio value of a number of time slots allocated for Forward-Link (FL) and a number of time slots allocated for Reverse-Link (RL); if the TDD ratio value is not an integer, grouping Mobile Stations (MSs) into multiple groups and generating group index information; and transmitting, to the MSs, control information including the TDD ratio value and the group index information.
