在本文中，我们考虑异构LTE网络，其中毫微微小区根据[1]中描述的两种模型（即双带和NxN）随机部署在宏网络中。毫微微小区被建模为封闭小区，即只有组成员UE可以与毫微微小区相关联。因此，在封闭小区附近的非成员UE可能经历主导干扰，并且使这些UE处于中断。我们在一个实际的部署几何性能，并讨论了自主功率控制方法，它允许显着降低中断概率，我们评估宏和毫微微小区之间的资源划分方法，进一步提高了宏用户的性能。
In this paper we consider a heterogeneous LTE network where femto cells are randomly deployed in a macro network according to the two models described in [1], namely dual-strip and NxN. Femto cells are modeled as closed cells, namely only group member UEs can be associated with the femto cells. Therefore, dominant interference may be experienced by non-member UEs that are in proximity of a closed cell and leave these UEs in outage. We show geometry performance in a practical deployment, and discuss an autonomous power control method, which allows to dramatically reduce the outage probability, and we evaluate a resource partitioning method between macro and femto cells that further improves the performance of macro users.
