ABSTRACT:
Disclosed is an apparatus and a method for transmitting a control channel message, which can reduce resource waste in an OFDM system multiplexing and using a Block Resource Channel (BRCH) and a Distributed Resource Channel (DRCH) in a frequency axis. The apparatus includes a controller for generating a predetermined field and outputting a control channel message including the predetermined field, the predetermined field indicating a precoding index when a common pilot is used for data demodulation in a mobile station and indicating a pilot format of a dedicated pilot when the dedicated pilot is used for data demodulation in the mobile station, the precoding index indicating a weight value for beam-forming of each antenna; and a transmission module for converting the control channel message into a wireless signal and transmitting the wireless signal to the mobile station. The apparatus and method can reduce the resource waste of a control channel by inserting different pieces of information into a predetermined field included in the control channel message according to the channel type and the multiplexing mode of a resource channel in an Orthogonal Frequency Division Multiplexing (OFDM) system, and enables the efficient use of resources by transmitting different types of control information through redundant bits of a control channel message.
