A Novel Distributed Power Allocation Scheme for Coordinated Multicell Systems

Coordination between Base Stations (BSs) is a promising solution for cellular wireless systems to mitigate intercell interference, improving system fairness, and increasing capacity in the years to come. The aim of this manuscript is to propose a new distributed power allocation scheme for the downlink of distributed precoded multicell MISO-OFDM systems. By treating the multicell system as a superposition of single cell systems the authors define the average virtual Bit Error Rate (BER) of one single-cell system, allowing them to compute the power allocation in a distributed manner at each BS.
