Increase in capacity - and especially capacity density, i.e., capacity per sqmile - is the main driver to LTE rollouts. The in
creased efficiency in the utilization of spectrum resources together with the higher density of cells and the addition of a small-cell layer allow operators to address the increase in data traffic while lowering per-bit costs. But to fully benefit from LTE performance (and ability to use a frequency reuse of 1), operators need to carefully manage interference to minimize its impact.
We just finished a paper that looks at interference management in LTE networks both from the radio access networks (RAN) and the user equipment (UE) perspective, and discusses what are the new interference management tools in LTE and LTE Advanced. There are promising new developments in this area -- many still in their development phase -- that increase the granularity and sophistication of interference management and are likely to fundamentally change the way operators manage interference today.
