Dynamic Algorithms in Multi-user OFDM Wireless Cells
This paper presents several results on dynamic OFDMA systems. It addresses especially the algorithmic complexity involved with several resource allocation approaches, sub-optimal heuristics for the use in practical systems, the related signaling overhead and modifications to the IEEE 802.11 protocol stack. It is argued that for the generation of dynamic OFDMA resource allocations very good sub-optimal methods exist while the loss due to signaling can be kept low for a large range of system parameters. Finally, an outline of the integration of dynamic OFDMA schemes into OFDM-based IEEE 802.11 systems is presented, providing significant performance benefits for such wireless local area networks.
