摘要： 针对LTE技术上行链路干扰问题，综合分析现存的各种小区间干扰抑制技术，提出一种新的小区间干扰协调方案，包括频带分配和能量分配2个步骤。将干扰少的频带分配给离基站远的用户，采用集中式能量分配算法分配合适的发射功率。通过计算机仿真，将该方案与现有方案在吞吐量、效能、时延方面进行对比，可取得较好的实验效果。

Abstract: Aiming at LTE technology uplink interference problem, based on comprehensive analysis of existing various kinds of interference suppression technology, this paper presents a new uplink interference coordination scheme, which includes two steps, frequency band distribution and energy distribution. Less interference frequency band is assigned band to the users who are far from the base station, and centralized energy distribution algorithm is used to allocate appropriate power. After the computer simulation comparison with the existing scheme in throughput, efficiency, time delay, better experimental result is achieved.
