| 随着智能终端的大量使用,使得传统的异构网络很难满足用户对数据速率的追求,面对这样的需求,小小区技术成为了未来移动通信的热点.然而在此场景下,小区间干扰严重制约着系统容量的提升.为了解决这一问题,一些小小区关闭策略被提出,如随机关闭、基于负载关闭等算法,但是这些方法的应用都没有考虑小区的系统容量.所以对基于每个小小区基站关闭前后带来系统容量增益进行了研究,有效地选择合适的小小区基站关闭策略,来减少小区间干扰,从而提高小区的系统容量.最后,仿真比较了基站在全开情况以及随机关闭和基于负载状况关闭的系统吞吐量,结果验证了所提方案的有效性. |

| Abstract: |
| With the using of intelligent terminal,which makes the traditional heterogeneous network is hard to satisfy our customer′s demand of data rate,in the face of such requirements,small cell technology become the focus of future mobile communication.Under this scenario,however,interference seriously restricts the system capacity of ascension.In order to solve this problem,a few small cell closed strategies have been proposed,such as random close,based on the load algorithm,but these methods can not consider the system capacity.So this article is based on each small cell before and after the closing system capacity gain,effective to choose the appropriate small cell closed,to reduce the interference between them,so as to improve the system capacity of community.Finally,the simulation comparison of the base station in fully open and random close and based on the load status of system throughput,the results verify the effectiveness of the proposed scheme. |
