METHOD FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS ACCESS SYSTEM AND APPARATUS FOR SAME
First Claim
1. A method for receiving data in a wireless access system, the method comprising:
- when a first user equipment fails to recover data from a first signal being received from a base station due to an interference caused by a second user equipment, requesting, by the first user equipment, retransmission to a neighboring second user equipment;
receiving, by the first user equipment, a second signal from the second user equipment; and
recovering, the first user equipment, the data from the first signal by using the second signal,wherein user equipments other than the first user equipment and the second user equipment are scheduled by the base station at a time point when the second signal is transmitted.

Abstract
Disclosed are a method for transmitting and receiving data in a wireless access system supporting relay nodes, and an apparatus for same. In particular, the present invention comprises the steps of: sending a request for a retransmission to an adjacent second terminal, in case the recovery of data from a first signal received from a base station fails due to interference by the second terminal adjacent to a first terminal; the first terminal receiving a second signal from the second terminal; and the first terminal recovering data from the first signal, using the second signal, wherein the base station schedules a terminal other than the first and second terminals at the point of transmitting the second signal.
