Downlink resource scheduling technique for maximized throughput with improved fairness and reduced BLER in LTE

This paper proposes a downlink resource scheduling technique for maximized throughput with reduced Block Error Ratio and improved fairness among different users across the cellular region. Resources are allocated to users on the basis of Channel Quality Indicator feedback values in a way that the data rates are increased without compromising on Block Error Ratio and fairness. Channel Quality Indicator feedback values provide critical information about the channel, which enables the scheduler to perform radio resource management functions in the downlink. Simulations are performed on a link level simulator for different scenarios. Results of simulations have been demonstrated, thoroughly explained and compared with the existing scheduling techniques designed for high data rates with and without fairness.
