A cutting plane optimization algorithm for intra-cell link adaptation problem

Link adaptation of a wireless cellular network is of much attention due to the desire of maximizing both the a erage lin throughput and co erage reliability, which have conflicting effect on each other. In this paper, the intra-cell lin adaptation problem is formulated as a non-differentiable constrained optimization problem to maximize average link throughput while guaranteeing the best possible coverage reliability. To achieve this, a cutting plane optimization algorithm is employed. The performance of our method: adaptive modulation/coding with power management (AMCWPM) using proposed algorithm is compared with that of an adaptive modulation/coding (AMC) with no power management. Simulation results show that the performance of our method improves both average link throughput and coverage reliability by at least 10% while in each case the other parameter (i.e. respectively, coverage reliability and average link throughput) is hold as much as that of the AMC with no power management.
