Abstract

This paper proposes a time-frequency scheduling algorithm to maximize the satisfaction of users served by an orthogonal frequency division multiple access (OFDMA) system. The satisfaction oriented resource allocation (SORA) algorithm takes into account in its formulation the channel quality, quality of service (QoS) requirements and effect of past allocations, so as to select, in an intelligent way, the set of users that can be more easily satisfied according to the system conditions.
