Publikováno v: International Journal of Electronics and Telecommunications, Vol vol. 65, Iss No 1, Pp 85-93 (2019)

In this paper, we propose a new algorithm that improves the performance of the operation of Handover (HO) in LTE-Advanced (LTE-A) networks. As recognized, Mobility Management (MM) is an important pillar in LTE/LTE-A systems to provide high quality of

Since the dawn of mobile communication systems, reducing the cell size has been one option to increase the signal-to-interference-plus-noise ratio (SINR) in both links. The impact of this reduction can be perfectly understood by considering Shannon�

Publikováno v: VTC Spring

Uncoordinated deployment of HeNBs has been widely considered, in the research community. However, due to economic or physical constraints, a coordinated deployment of HeNBs can also be considered. This work studies a selected examples of HeNB deploym

Performance Evaluation and Packet Scheduling in HeNB Deployments

Autor: Giuseppe Piro, Fernando J. Velez, Rui R. Paulo

Publikováno v: VTC-Fall

The unsupervised and chaotic deployment of Home eNBs (HeNBs) is leading to high levels of interference. To understand the behaviour of the interference of these uncoordinated deployments is vital to reach significant capacity improvement and also to
