Abstract :
We propose a fault-management channel (FMC) to address the problem of indoor-RAS (radio access station) faults and analyze it by using an optimization method. To reduce the complexity of the optimization problem, we also propose a suboptimal algorithm that is based on the FMC: an equal power allocation algorithm (EPA). Our main contributions are as follows: 1) proposing a solution for indoor-RAS faults; and 2) presenting an efficient suboptimal algorithm (EPA) for the improvement of fairness. Through intensive simulations, we evaluate the performance of our proposed algorithm with respect to fairness, spectral efficiency, and a new proposed metric that considers spectral efficiency and fairness together.
