摘要： A method for transmitting and receiving a control channel message in a mobile communication system using multiple antennas is provided. A base station determines whether a common pilot is used or a dedicated pilot is used. It also determines whether a corresponding Multiple Input Multiple Output (MIMO) mode is a Multi-CodeWord (MCW) MIMO mode or a Single CodeWord (SCW) MIMO mode, and determines whether knockdown precoding is used or ready-made precoding is used. The base station generates a control channel message field including a pilot pattern and a precoding type according to the determination results, and transmits the generated control channel message to the terminal. The terminal receives a control channel message transmitted from a base station. The terminal determines whether a common pilot is used or a dedicated pilot is used, whether a corresponding MIMO mode is an MCW MIMO mode or an SCW MIMO mode, and whether knockdown precoding is used or ready-made precoding is used. The terminal analyzes the control channel message field according to the determination results, and determines a data reception method according to the analysis result.
