Abstract:
|
Effective interference management is a technical
challenge of utmost importance for emerging OFDMA-based
technologies such as Long Term Evolution (LTE) and Worldwide
Interoperability for Microwave Access (WiMAX). Static Intercell
Interference Coordination techniques including Soft Frequency
Reuse (SFR) have enjoyed acceptance among mobile operators
as a solution to deal with this problem mainly due to their low
complexity and easy implementability. However, recent results
indicate that the performance of default SFR settings directly
applied to realistic cellular deployments is quite suboptimal and
hence optimization is mandatory. This paper addresses this issue
by presenting a novel multiobjective framework able to achieve
accurate fine tuning of SFR and hence, enhance system capacity
and cell edge performance while reducing energy consumption. |
