An Integrated Radio Resource Allocation Framework for Enhanced Uplink UTRA-FDD with Fixed Relay Stations

In this paper, an Integrated Radio Resource Allocation (IRRA) framework is proposed for enhanced uplink UTRA-FDD with fixed relay stations (FRSs). It comprises two entities: Relaying Link Scheduler (RLS), and Transmission Mode Aware Packet Scheduler (TMAPS). RLS is responsible for the scheduling of user transmission modes (direct or relaying) and routes, whereas TMAPS is responsible for the scheduling of user transmission time and rates. These two entities operate synchronously, periodically, and with coordinated interactions. System level simulation results show that this framework is able to ensure significant gains in terms of cell throughput.
