Method and System for Communication Between a Plurality of Femtocells to Mitigate Interference Between the Femtocells
Aspects of a method and system for communication between a plurality of femtocells to mitigate interference between the femtocells are provided. In this regard, a first of a plurality of femtocells in a network may receive interference information from one or more other femtocells, one or more base stations, and/or one or more communication devices in the network.
