CoMP and interference coordination in heterogeneous network for LTE-Advanced

Abstract

Coordinated Multipoint Transmission and Reception (CoMP) and Enhanced Inter-cell Interference Coordination (eICIC) are two important features in 3GPP LTE-Advanced. Through CoMP and interference coordination, system performance, especially cell edge throughput is significantly improved. In 3GPP LTE-Advanced, CoMP discussion has been focusing on dynamic coordination schemes which require fast links between coordinating points. On the contrary, eICIC is considered as a semi-static co ordination scheme which is enabled through X2 backhaul interface. This paper provides an overview of CoMP and eICIC schemes discussed in the standardization process of LTE-Advanced. Performance results are provided to evaluate a novel scheme which combines dynamic CoMP and semi-static eICIC coordination under super-cell heterogeneous network deployment.
