Uplink QoS Scheduling for LTE System

In this paper, we propose a QoS uplink scheduling algorithm for LTE collaborating with delay estimation. Unlike downlink scheduling, uplink scheduling cannot incorporate packet delay information due to specification constraints of LTE. The limited information results in difficulty ensuring a QoS when conventional scheduling algorithms are employed. Using a delay estimation tailored to LTE, we have shown that the uplink performance of the proposed QoS scheduling scheme can be improved more than 11% even with a simple estimation via simulations.
