Fair resource allocation for inband relaying in LTE-Advanced

In this work, we investigate the issue of fair resource allocation in relay-enhanced wireless networks. Our focus is on Type-1 relays as proposed for LTE-Advanced. The latter operate as inband relays, i.e., the backhaul and access link must share resources in the time domain. For the case of full buffer traffic on the downstream, we demonstrate how the data flow from the network to the terminals can be arranged in a fair manner. This includes different strategies for resource partitioning at the macro base station, as well as frequency-selective scheduling at both base station and relay nodes.
