| 摘要 |
A method and apparatus for transmitting a packet data control channel in an OFDMA wireless communication system are provided. The method includes dividing control information for user data transmitted during a specific frame into a packet data control channel to be transmitted in a diversity mode and a packet data control channel to be transmitted in an Adaptive Modulation and Coding (AMC) mode; encoding and modulating the packet data control channel to be transmitted in the diversity mode and the packet data control channel to be transmitted in the AMC mode; and mapping the encoded and modulated packet data control channels to sub-carriers, before transmission.
