Performance analysis of scheduling algorithms in the relay-aided cellular networks

This paper focuses on multi-user scheduling in downlink relay-aided cellular network. Based on conventional scheduling rules (Round Robin (RR), Max Carrier-to-Interference ratio (Max C/I), and Proportional Fair (PF)), we propose backhaul and access scheduling algorithms under centralized and distributed mechanism, respectively. We evaluate and compare the network performance through system-level simulation. The results show that both centralized mechanism and distributed mechanism have pros and cons. Centralized mechanism performs better at the cost of more signalling and complexity.
