Abstract :
A TDD-OFDMA framework is designed for broadband wireless access. The main features of our design are predefined MAP structure, scalable OFDMA system with frequency overlay and MIMO mode switching scheme. An extensive system level simulation study has been carried out in the practical channel conditions. Our results show that the average sector throughput can be improved by 25~50%, and the size of MAP message is reduced by more than 50%.
