宏小区和小小区用户之间的幅度空间共享

Amplitude Space Sharing among the Macro-Cell and Small-Cell Users

Yafei Tian, Songtao Lu, Chenyang Yang

摘要:

对无线数据服务的巨大需求将很快超过当前同构蜂窝架构的能力。一种新兴的解决方案是将小小区网络与宏小区网络重叠。在本文中,我们提出了一种幅度空间共享(ASS)的方法之间的宏小区用户和小小区用户。通过传输层设计和数据速率优化,保证了信号和干扰在每个接收端是可分离的,并使网络和速率最大化。采用Han-Koboyashi编码,推导出一个小小区场景的最优功率分配,并为多个小小区场景开发了一种简单的ASS传输方案。仿真结果表明,与其他干扰管理方案相比,具有很大的优越性。

英文摘要:

The crushing demand for wireless data services will soon exceed the capability of the current homogeneous cellular architecture. An emerging solution is to overlay small-cell networks with the macro-cell networks. In this paper, we propose an amplitude space sharing (ASS) method among the macro-cell user and small-cell users. By transmit layer design and data-rate optimization, the signals and interferences are promised to be separable at each receiver and the network sum-rate is maximized. The Han-Koboyashi coding is employed and optimal power allocation is derived for the one small-cell scenario, and a simple ASS transmission scheme is developed for the multiple small-cells scenarios. Simulation results show great superiority over other interference management schemes.
