A fair and power saving uplink scheduling scheme for 3GPP LTE systems

In this paper, we propose an uplink resources allocation strategy for Long Term Evolution (LTE) systems. In time domain, the scheduler aims at ensuring more fairness by using a metric updated every new uplink transmission round, giving higher priority to users who are the farthest from their minimum QoS requirements. Then, resources are allocated in a way to achieve the required rate with the minimum number of resources blocks, respecting channel quality and power limit. Obtained results prove that the proposed scheme helps the system to fairly and efficiently redistribute the available radio resources and to reduce uplink power consumption.
