Abstract

In this paper, we look at resource allocation for OFDMA downlink with frequency dependent modulation and coding. Physical layer resource blocks are allocated with an objective to satisfy the bit rate demands of user applications. This schematic can be applied for the guaranteed bit rate mode in LTE. For this requirement we layout performance objectives of scheduling. Allocation methods that can solve the problem with low complexity are presented. Specifically, a joint resource block allocation and admission control framework is proposed for situations of high network load. Numerical results are shown using channels from a measurement.
