基于有限回传链路的小基站网络重叠协作方法研究

摘要

In this paper, we describe an inter-cel overlapping coordination approach to managing interference in a smal-cel network with backhaul constraints. We propose a novel inter-cel overlapping coordination algorithm based on downlink coordinated beamforming to cancel downlink interference between different smal-cel base stations and increase system throughput. Simulation results show that our proposed algorithm significantly improves throughput in the system.%采用一种小区间重叠协作的方法，解决了基于有限回传链路的小基站网络中的干扰管理问题。提出了一种新的基于下行协同波束赋形的小区间重叠协作算法，用于消除小基站网络中不同小基站之间的下行干扰，提高系统吞吐量。仿真结果显示，提出的算法能够显著提升以吞吐量为指标的系统性能。
