A new channel-aware LTE-A uplink resource allocation scheduling algorithm

New cellular networks standardized by 3GPP as LTE and LTE-A aim to provide scalable resources optimizing both system performance and user satisfaction. In order to achieve this goal the scheduler algorithm becomes of upmost importance. Thus a number of different resource allocation algorithms have been suggested. However, the uplink has been little covered due to the fact it poses more specific constraints and it is quite complicated to balance the trade-off between channel state information, system throughput and user perceived throughput. In this paper we propose a new resource allocation algorithm that tries to balance the advantages of two previously suggested ones. We also introduce a new parameter, the user ratio, which allows us to explicitly quantify the trade-off between fairness, system throughput and user throughput for different channel conditions.
