A Dynamic Hybrid Clustering Scheme for LTE-A Networks Employing CoMP-DPS

In this paper, we propose a low compexity Dynamic Hybrid Clustering (DHC) scheme for LTE-A networks employing Coordinated MultiPoint with Dynamic Point Selection (CoMP-DPS). Although CoMP-DPS is considered to be a simpler CoMP scheme, its simplicity allows us to define more efficient cell clustering procedures. Thus, DHC is able to provide backhaul load balancing for the eNBs while offering high quality wireless connections and high data rates to the users. DHC exploits the feedback from the mobile devices and takes into account the backhaul load conditions in order to adjust the backhaul latency to tolerable levels and maintain optimal channel quality. Numerical results and comparisons with other schemes are provided showing improved performance by the proposed solution.
