Like in most cellular system deployments, the overall system spectral efficiency is not range limited or noise limited, but interference limited. Inter-cell radio resource management coordinates resource allocation between different cell sites by using multi-user MIMO techniques. There are various means of inter-cell interference coordination (ICIC) already defined in the standard.
