Self-Organizing Networks (SON) is currently seen as a key lever to improve network performance and simplify its management. This paper considers ?-fair schedulers in an Orthogonal Frequency-Division-Multiple Access (OFDMA) network. The convergence of the ?-fair scheduler is analyzed. Closed-form formulas are given for certain cases to calculate the scheduling gain, as well as a Monte-Carlo method, for a MIMO channel. A capacity-coverage algorithm based on the ?-fair schedulers using observable Key Performance Indicators (KPIs) is proposed.
