摘要: 针对LTE无线通信系统上行链路,提出一种联合HII和OI的干扰协调方法.与以往提高整个网络吞吐量或小区边缘用户速率为目标的传统干扰协调方法不同,该方法从满足用户的实际通信质量要求出发,以提高用户满意度为目标,并首次联合使用了LTE R8标准定义的2个信息(高干扰指示HII和过载指示OI)进行频域协调和功率调整.仿真结果表明,该方法相比传统的干扰协调方法能明显提升用户满意度,具有较高的实用价值.

Abstract: An uplink interference coordination scheme by combining HII and OI is proposed for the OFDMA wireless system. While the traditional schemes aim to improve rate of users in the whole network or at the cell edge, the proposed scheme targets the satisfaction of all the users in the network. In practice, high interference indicator (HII) and overload indicator (OI) are combined. The simulation results show that the proposed scheme significantly improves user satisfaction compared with the traditional schemes and it is a good candidate for practical systems.

Key words: LTE, ICIC, HII, OI, user satisfaction
