Abstract
A method of transmitting and receiving a control channel in a wireless communication system is provided. A base station allocates a data channel to a radio resource, adds start position information of the data channel into a payload of a control channel, and performs signaling for indication information on the start position information added into the payload of the control channel to a terminal. Accordingly, the legacy system and the enhanced system can efficiently transmit a control channel.
