In order to avoid inter-cell interference, OFDMA networks are flexible in terms of radio resource management techniques, supporting different frequency reuse schemes (FRSs), which in turn, may decrease inter-cell interference and increase network performance. However, because most of them are based on fix patterns, these FRSs cannot cope with the uneven distribution and dynamic behavior of the traffic...
The new relay-based architecture for mobile WiMAX that will allow multihop communication imposes a demanding performance requirement on relay stations. The frame structure used for transmission plays an important role in the design of multihop networks as it manages the channel access and therefore determines the resulting network capacity. In this work we firstly propose a new simple and flexible...
