Coordinated multipoint (CoMP) transmission/reception has been adopted as a key technology to alleviate the intercell interference (ICI) in fourthgeneration (4G) mobile communication. This article reviews the state of the art in limited-feedback CoMP systems research. We first give an overview of recent related work in feedback-based coordinated transmission and then provide a performance analysis...
Cellular networks are evolving towards a mixture of macro cells and small cells, thereby increasing the number of cell sites to serve traffic hotspots. This trend poses challenges for managing inter-cell interference and traffic offloading, since a multitude of transmitters of different power classes creates imbalance between the downlink and uplink coverage. Conventional network planning and interference...
