Abstract: Disclosed herein relates to a resource allocation method for a machine type communication (MTC) device. The resource allocation method for the MTC device includes allocating a control channel with respect to a user terminal to a first time domain of a sub frame, and mixing at least one of a control channel with respect to the at least one MTC device, a data channel with respect to the user terminal, and a data channel with respect to the MTC device in a second time domain of the sub frame, and allocating the mixed channel to the second time domain of the sub frame. Accordingly, in a wireless communication system, control information and data may be transmitted and received to and from the MTC device while maintaining compatibility with the user terminal.
