Enhanced Inter-cell Interference Coordination and Multi-radio Coexistence

In this chapter we discuss the practical and theoretical aspects of two important features that were included in the recent releases of LTE to address inter-cell interference problems in LTE systems and in-device inter-radio interference issues, where both problems can adversely affect the system capacity, user throughput, and normal operation of the LTE system.

One of the most promising and cost-effective solutions to improve the system capacity in cellular networks is to increase the node density; i.e., to deploy low-power nodes such as relays, pico-cells, femto-cells, and remote radio heads overlaid by macro-cell networks. The new network architecture, known ...
