METHOD AND APPARATUS FOR RELAYING DATA IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2010/093143

A3

A method for relaying data in a wireless communication system comprises the steps of: enabling a second subframe to receive data transmitted from a base station to a first subframe; and enabling a third subframe, which is positioned after the second subframe and separated from the latter by one or more subframes, to relay the data to a user equipment, wherein at least the first subframe or the second subframe is a non-detection subframe for which the user equipment does not attempt to detect data. The wireless communication system according to the present invention enables efficient data transmission between the base station and a relay station as compared to conventional subframe-setting systems. Further, the wireless communication system according to the present invention enables data transmission with improved wireless resource allocation efficiency.
