摘要
宏微紧密协同的新型综合解决方案LIGHT-Net,通过立体的覆盖网络提升LTE承载能力来解决热点区域密集用户的高流量需求和边缘网络的盲点覆盖问题,实现高效、节能的轻资产精品网络。LIGHT-Net宏微协同组网时,采用同频部署可以最大化频率资源利用率,但随着微基站数量的增多,宏小区和微小区间、微微小区间存在严重的层间干扰和同层干扰,因此在实际部署中,需要采用有效的小区间干扰抑制技术以降低干扰。
The new comprehensive solution for macro cel and smal cel tight cooperation is cal ed as LIGHT-Net, which constructs a tri-dimensional coverage network to increase LTE carrying capacity to meet the high traffic requirement for dense users in hot-spots and solve the issue of coverage holes in cel edge region. The aim of LIGHT-Net is to achieve the high quality network with high efficiency, energy saving and light-assets. When macro cel and smal cel are coordinately deployed in LIGHT-Net, co-channel deployment can maximize the spectrum utilization efficiency. But with the growth of the number of smal cel s, the inter-layer interference between macro smal cel s and intra-layer interference between smal cel s are becoming more se-vere, thus the efficient inter-cel interference suppression techniques should be adopted to mitigate the interference in practi-cal deployment.
