    • PURPOSE: A method of avoiding inter-cell interference (ICI) in a wireless access system is provided to reallocate resources causing collision in the relay node coverage to avoid ICI while implementing the full dynamic resource allocation (RA) method by each cell. CONSTITUTION: A response for a downlink signal transmitted to each base station is overheard by terminals from the n+4th sub frame. When at least one NACK is included in responses for a downlink signal transmitted by the terminals, a resource region allocated to the terminals in the n-th sub frame is reallocated. Control information showing the reallocated resource region is transmitted to the each base station. An uplink signal transmitted in the n-th sub frame to the terminals is retransmitted based on the control information in the n+8th sub frame.

    • 目的:提供一种在无线接入系统中避免小区间干扰(ICI)的方法,以重新分配导致中继节点覆盖中的冲突的资源,以避免ICI同时由每个小区实现全动态资源分配(RA)方法。 构成:发送到每个基站的下行链路信号的响应被第n + 4子帧的终端窃听。 当在由终端发送的下行链路信号的响应中包括至少一个NACK时,分配给第n个子帧中的终端的资源区被重新分配。 显示重新分配的资源区域的控制信息被发送到每个基站。 基于第n + 8个子帧中的控制信息重发在第n个子帧中发送到终端的上行链路信号。 (附图标记)(AA)第一时区; (BB)第二时区; (CC)频率; (DD)非重叠(非合作)案件; (EE)资源叠加(合作)案例; (FF)时间
