Abstract :
To improve system throughput and extend coverage, multi-hop relaying is a promising technology in wireless communication systems. Thus, multi-hop relaying is world-widely gaining huge attention as a key research item. Nevertheless, it may cause longer delay and degrade resource efficiency at the cost of the benefits due to multi-hop relaying. In this paper, we propose a traffic adaptive uplink scheduling algorithm for relay station, which could be applied to the centralized multi-hop system such as IEEE 802.16 MMR efficiently. The proposed algorithm can overcome those defects of multi-hop relaying technology and enhance system performance.
