DELAY IMPROVEMENT USING EFFICIENT HARQ-SCHEDULER IN LTE

Long Term Evolution (LTE) is standardised by the 3GPP to provide a high data rate up to 100 Mbps/50 Mbps in Rel8 for downlink/uplink transmission respectively and effectively increases with the addition of new features including MIMO, CA. LTE effectively can operate with scalable bandwidths ranging from 1.4MHz up to 20MHz with varied Resource blocks ranging from 6 to 100. Resource allocation is a key role in order to achieve the goals of the Long Term Evolution (LTE) and scheduling mechanisms incorporated in the MAC Layer of the architecture contribute to this goal. Scheduling is the process in which the resources are allocated in both Time and Frequency domain to users. In this paper, evolved scheduling algorithm is proposed for reducing the delay for the application of critically without compromising the cell throughput and fairness in comparison with Round Robin, Best-CQI schedulers.
