A framework for resource allocation in OFDM broadcast systems

We consider an OFDM broadcast channel (BC) where resources have to be allocated among M users according to a scheduling policy. In this framework, we study four different schedulers, namely the maximum weight matching (MRMS), the minimum rates (MRS), the minimum sum power (MSPS) and the maximum throughput (MTS) scheduler. We present efficient algorithms and derive the corresponding stability regions. Moreover bounds on the average expected buffer length are presented.
