We propose a efficient semi-distributed resource allocation scheme for OFDMA relay-enhanced downlink systems. Firstly, an adaptive subframe partitioning (ASP) algorithm that considers user's queue length and achievable data rate is used by base station to assign resources to relay stations. Regarding the slot allocation, we suggest two ways to extend conventional single-hop scheduling algorithms into multihop scenarios: link-based and end-to-end approaches. Simulation results indicate that the… CONTINUE READING
