ABSTRACT:
A method and apparatus for transmitting/receiving a shared control channel message in an Orthogonal Frequency Division Multiple Access (OFDMA) wireless communication system are provided. The message transmission apparatus receives feedback information from a terminal; determines whether to transmit data by applying preceding; and transmits, in the shared control channel message, control information whose message type is differently set according to the application of the preceding. The message reception apparatus receives the shared control channel message from a base station; determines a message type of the shared control channel message; and if the message type is a Transmit Diversity (TD)-Forward Link Assignment Message (FLAM), demodulates data by at least one of Single Input Single Output (SISO) and Spatial Time Transmit Diversity (STTD) as indicated by the TD-FLAM.
