摘要

在异构网络中，部署多种小功率基站，会出现大量的“小区边缘区域”，边缘用户的性能会受到影响。为此，提出了一种边缘用户小区选择算法，通过发送端进行预编码抑制干扰，提高用户接收到的信干噪比。根据小区当前用户数，动态地调整给微小区边缘用户参考接收信号添加的偏置值，避免边缘用户接入用户数过多的拥堵小区。仿真结果表明，该算法与参考算法相比，能够有效降低宏小区负载，平衡不同微小区间负载，提高轻载微小区的网络吞吐量和资源利用率。

Abstract

A large number of “cell-edge area”can arise when deploying a variety of low-power base stations in heterogeneous networks

this can affect the property of edge users. So a cell selection algorithm for edge user was proposed

by using the transmitting end to precoding to suppress interference and improve user received signal-to-interference-plus-noise-ratio（SINR）. According to the current number of user in the cell

dynamically adjust the reference received signal added bias to the picocell edge users

to avoid edge users accessing heavy loaded cells. The simulation results show that

compared with the reference algorithms

the proposed algorithm can effectively reduce the load of macrocells

balance the load between different picocells and improve the throughput and resource utilization of the light load picocells.
