Abstract
An iterative algorithm for the multiuser fair scheduling problem of adaptive OFDMA systems is presented. It uses iterative local search with kopt switches in the combinatorial solution space. The algorithm can be used with different scheduling criteria like proportional fairness and maxmin fairness, both for constant and adaptive allocation of power to subcarriers/resource blocks. The algorithm is applied to a simplified model of 3GPP LTE and its properties are simulatively investigated in the constant power and the adaptive power case.
