Abstract: A method is described for processing a signal at a relay node in a wireless communication system. More specifically, in one embodiment, the relay node receives a codeword broadcast from a source node. The codeword is partitioned into a plurality of sub-blocks. Then, the relay node generates two network encoded codewords by combining linearly the plurality of sub-blocks, and transmits the two network encoded codewords to a destination node. The destination node detects the codeword by using a zero-forcing receiver.

Abstract: Disclosed is a method for receiving a coordinated signal by a terminal on the basis of a terminal-to-terminal direct communication. Specifically, the method comprises the steps of: receiving a coordinated signal including an interference signal and a valid signal from a relay terminal; detecting an interference signal component by performing a first maximum-ratio combining on the coordinated signal; transmitting a first feedback information to the relay terminal if the detection of the interference signal component fails, and detecting a valid signal component by performing a second maximum-ratio combining if the detection of the interference signal component is successful; and transmitting a second feedback information to the relay terminal if the detection of the valid signal component fails.
