METHOD FOR AVOIDING INTER-CELL INTERFERENCE IN A WIRELESS ACCESS SYSTEM

摘要

A method for a relay node (RN) to avoid inter-cell interference (ICI) in a wireless access system is provided. The method includes: overhearing a PDCCH transmitted by a plurality of BSs sharing the RN to terminals of each BS in the nth subframe; decoding the PDCCH from the n+1th subframe to the n+2th subframe; reallocating resource area to the terminals; transmitting control information representing the reallocated resource area to each BS; overhearing and decoding a PUSCH to each BS in the n+4th subframe; transmitting the decoding result to each BS; overhearing a PDCCH updated at n+8th subframe; and retransmitting the PUSCH transmitted at the n+4th subframe to a BS(NACK) in the n+12th sub frame.
