Abstract
Long Term Evolution (LTE) is rapidly flourishing in the global market due to its speed, coverage, relative ease of deployment, and consistency. However, Quality of Service (QoS) provisioning scheme is not fully defined for LTE, and it is left open for researchers to explore. In this paper, we propose a QoS provisioning technique for LTE. This technique involves a two-level scheduling scheme, consisting of a Rate-Controlled Priority Queuing Discipline (RCPQD) and a Deficit Weighted Round Robin Queuing Discipline (DWRRQD). To provision fairness, the scheduler considers the buffer content of the non-real-time applications, while priority is used to take differentiation of RT applications into account. The results show relative improvement in the performance of both real-time and non-real-time applications.
