摘要： A method and apparatus for transmitting common control information by a base station in a wireless communication system are provided. The base station determines whether a first system and a second system different from the first system coexist in a wireless communication system. When the wireless communication system is a coexistence system, the base station indicates information for coexistence of the first system and the second system, position and size information of a resource allocation zone where common control information for the second system can be transmitted, and information necessary for decoding of the resource allocation zone, through a first information element in a downlink subframe where resources are occupied for the first system. The base station transmits the common control information of the second system in the resource allocation zone where the common control information can be transmitted.
