摘要
针对HII和OI处理的协调性,提出一种联合HII和OI的小区间干扰协调方案。方案根据目标小区接收到的HII和OI,确定目标小区中心需要调整PRB分配的用户和需要调整发射功率的用户。并根据不同的边缘负载情况分配频率资源。MATLAB仿真结果表明,新的小区间干扰协调方案与传统的小区间干扰协调方案相比能够有效抑制小区间干扰,提高用户平均吞吐量。
As the coordination of the process of HII and OI, a kind of interference coordination scheme by jointing HII and OI was proposed. According to the received HII and OI of target cell, eNodeBs select and determine the users need to be adjusted the PRB assigning and the users need to be adjusted the transmission power. Then eNodeBs assign frequency resources depend on the different edge load situation. MATLAB simulation results show that the new interference coordination scheme can effectively re duce inter-cell interference compared with the traditional interference coordination scheme, and improve the cell average throughout.
