Visible light communication (VLC) can offload the increasingly heavy traffic in LTE network, improving the spectral and energy efficiency without introducing additional interference. However, developing a scalable load balancing scheme with less handover overheads becomes an issue. In this letter, leveraging the location-sensitive feature of VLC channel, we propose a mobility-aware load balancing...
In co-channel deployment of macrocell and indoor femtocells, almost blank subframe (ABS) is considered as an effective enhanced inter-cell interference coordination strategy for mitigating downlink cross-tier interference. In this paper, a novel distributed dynamic ABS ratio setting scheme is proposed for dense residential femtocell deployment with closed subscriber group configuration. Both the overall...
In order to meet the requirement of wider bandwidth in IMT-Advanced, carrier aggregation (CA) is introduced by 3GPP to support bandwidth up to 100MHz in its LTE-Advanced standards. An LTE Rel.10 UE can aggregate up to 5 component carriers (CCs) simultaneously, but may be assigned only part of the total available CCs depending on its capability or traffic load. Thus, a proper CC selection method is...
