摘　　要：在频率复用因子为1的两跳固定中继节点的蜂窝移动通信系统中,基于现实移动业务分布的时变性和非均匀性,提出了新的中继信道分配策略。与传统的中继信道分配策略相比,该策略不需要BS之间的协作,也能严格控制相邻小区之间同频RS的干扰距离,降低同信道干扰,在较低的系统复杂度下,实现了无线资源的有效利用。In the cellular mobile communication system with two-hop fixed relay stations, a new relay channel assignment scheme is proposed for time-variety and non-uniform traffic distribution on the condition of frequency reuse factor being equal to one. Compared with the traditional relay channel assignment scheme, the proposed scheme could reduce the co-channel interference by controlling the distance co- channel distance between relay stations（RSs）, It makes full use of radio resource with low complexity without cooperation among base stations （SSs）.
