Implementation Challenges Facing User Equipment in Coordinated LTE Networks
Communications systems are often defined by their peak data rate.In order to break the system limitation due to the co-channel interference in cellular networks and to improve the cell-edge user experience, coordinated multipoint (CoMP) techniques have been developed and standardized for LTE Advanced systems. This paper demonstrates benefits of CoMP techniques and to discuss their practical implementation challenges in current 4G networks. Different CoMP scenarios and their challenges for a UE are explained in detail. Furthermore, the paper describes potential CoMP solutions that might be supported in beyond LTE-Advanced networks. Performance benefits are evaluated by Monte Carlo simulations in different CoMP scenarios.
