Motivated by the dramatically growing demand for high data rate wireless data services, cellular wireless communications standards fora such as Third generation partnership program (3GPP) in Europe and 3GPP2 in the U.S. have been actively involved in standardizing orthogonal frequency division multiple access (OFDMA) based air-interface for next generation cellular networks under the Long Term Evolution (LTE) and ultra mobile broadband (UMB) frameworks, respectively. Several novel technologies built upon OFDMA such as dynamic fractional frequency reuse (FFR), DFT spread OFDMA or single-carrier FDMA, pre-coded code division multiple access (CDMA) and advanced multiple antenna (MIMO) techniques have been included in the standards. In this tutorial, we start with a brief introduction on the evolution of cellular networks and then describe the novel aspects of the next generation systems. We emphasize the fundamental concepts and design tradeoffs involved, and discuss relevant algorithms for maximizing the performance using the various features in the standards.
