Abstract
Introduced by long-term evolution-advanced (LTE-A) cellular systems, coordinated multi-point (CoMP) transmission has shown remarkable aptitude for improving network performance. This paper proposes a novel CoMP technique for the downlink of two-tier heterogeneous LTE-A cellular networks. Thorough investigation is carried out to evaluate its performance in terms of total throughput, energy efficiency and outage probability. The effect of interference is also taken in to consideration in this regard. The proposed technique combines both dynamic point selection (DPS) and joint transmission (JT) CoMP schemes. Under the proposed CoMP technique, multiple transmitting base stations (BSs) selected dynamically from available macrocells and small cells coordinate to jointly serve a user. Extensive simulations are carried out for evaluating the performance of cellular networks integrating the proposed CoMP technique and also compared with that of non-CoMP, only JT and only DPS based schemes.
