Abstract
Provided is an apparatus and method for constructing a subframe to support a multi link in a multi-hop relay cellular network. In a first section of a subframe, a subframe for communication with a mobile station (MS) is constructed, and in a next second section of the subframe, a subframe for communication with a relay station (RS) is constructed. Therefore, resources can be efficiently used without interference between subframes, pilots can be flexibly used, advanced technologies can be easily applied, and overhead due to RS switching gaps can be reduced.
