In moderm OFDMA-based cellular networks, intercell interference is the main issue limiting the capacity of these systems. Recently, intensive research work has been focused on intercell interference coordination as it has been recognized as an important element to achieve seamless levels of quality of service. However, in most of the cases, this issue is addressed as a standalone issue. In this work, a novel channel state information feedback mechanism is proposed aiming at improving the system performance when static interference coordination techniques are also considered. By means of the proposed scheme, gains in terms of (1) users throughput, (2) cell edge performance and (3) energy efficiency are achieved with respect to existing aperiodic LTEbased mechanisms. Moreover, given the low complexity of the proposed solution, feasibility aspects are also discussed and a possible LTE implementation alternative is suggested.
