LTE system scheduling algorithm based on utility function

LTE system performance largely depends on the high efficiency of frequency domain resource scheduling. This paper presents a single-cell LTE Downlink scheduling model, and then introduces the economic concept of utility function in order to design a LTE system scheduling algorithm based on the utility function (UBS) and we simulate the algorithm. We simulate and compare throughput, fairness, packet loss, packet delay and other aspects of the algorithm and the classical scheduling algorithm. The simulation results shows that the UBS algorithm have better system performance and utility value.
