    • 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.
    • 公开了一种用于发送控制信道消息的装置和方法,其可以减少OFDM系统在频率轴上复用和使用块资源信道(BRCH)和分布式资源信道(DRCH)中的资源浪费。 该装置包括:控制器,用于产生预定的场,并输出包含预定场的控制信道消息,当公共导频用于移动台中的数据解调时,指示预编码索引的预定字段指示专用导频的导频格式 当专用导频被用于移动台中的数据解调时,预编码索引指示每个天线的波束成形的权重值; 以及传输模块,用于将控制信道消息转换成无线信号,并将无线信号发送到移动站。 该装置和方法可以根据正交频分复用(OFDM)中的资源信道的信道类型和复用方式,将不同的信息片段插入到控制信道消息中包含的预定字段中,从而减少控制信道的资源浪费 )系统,并且通过通过控制信道消息的冗余位发送不同类型的控制信息来实现资源的有效利用。
