Abstract
A wireless multi-hop relay communication system includes a terminal for transmitting an Automatic Retransmission reQuest (ARQ) block of a Media Access Control (MAC) layer in an access link, an access link relay station for determining if there is an error in the ARQ block received on the access link and for sending the ARQ block to an upper node over a relay link when the ARQ block has no error, and a base station for determining if there is an error in the ARQ block received over the relay link.
