摘要：
This paper details on the uplink scheduling algorithm for long term evolution advanced(LTE-A)system with relays.While emulating quality of service(QoS)-aware services with different bit-rate and delay budget requirements for the upstream direction,a new QoS-aware scheduling algorithm for in-band relays is proposed.In this work,an improved scheduling metric calculation method and bit-rate guarantee scheme is applied.Moreover,this algorithm proposes an efficient scheme for the backhaul link allocation which allows information of the most backlogged users to be transmitted first.Finally,this paper concludes with simulation results to demonstrate how the proposed resource allocation strategy improves the performance of the system.
