A dynamic downlink load control scheme with virtual coverage adjustments for two-tier LTE systems

Abstract

Abrupt increase in traffic load can cause traffic overloading situation, thereby degrading the performance of two-tier LTE systems, in which femtocells are overlaid with macrocells. In this paper, we propose a dynamic downlink load control scheme with virtual coverage adjustments for the two-tier LTE system, in which the coverage of hotspot macrocell is… (More)
