摘要：
Orthogonal frequency division multiplexing (OFDM)-based orthogonal frequency division multiple access (OFDMA) has emerged as a promising transmission technology for next generation wireless systems. In a multiuser scenario, adaptive radio resource allocation can significantly improve the performance of OFDMA systems. In this article, an overview of the major state-of-the-art approaches to adaptive resource allocation in the OFDMA systems is provided. Several open research issues are outlined.
