I. Introduction
In the upcoming wireless cellular systems such as LTE-Advanced or Beyond 4G systems, cells are densely deployed to meet the growing demands for connectivity and thus inter-cell interference becomes more critical [2], [3]. Hence, intensive research is going on to mitigate the inter-cell interference. From information theoretic perspective, it is well known that allowing all cells to operate in the same spectrum bandwidth (called full frequency reuse) maximizes the total system capacity. However, full frequency reuse may excessively degrade the performance of cell edge users unless inter-cell interference is properly managed. To this end many inter-cell interference coordination (ICIC) techniques were proposed, see [4] for a series of research. However, ICIC techniques assuming full frequency reuse often require complex coordination, scheduling and/or message passing among base stations (BSs) and mobile terminals (MTs) [5], [6].
