摘　　要：为了实现LTE-A要求的高速率和高频谱效率,需要对蜂窝小区进行更加精确的预测或干扰控制。文章提出了一种基于多小区集中式调度方案基础上的小区间联合资源分配的线性建模方法。由于方程组里包括了干扰功率、发射功率、目标SINR等参数,是一个比较精确的模型,且便于计算机实现。In order to achieve the high-speed and high -spectral -efficiency requirements of LTE -A, more precise forecast or interference control are needed for cellular systems. This paper proposes a new linear modeling of intercell joint resource allocation, based on multicell centralized scheduling. Including many parameters such as interferences, transmission powers, and the target SINRs etc, the equation group is an relatively accurate model and easy to compute.
