Combined Admission Control and Scheduling for QoS Differentiation in LTE Uplink

Long term evolution (LTE) architecture shall support end-to-end quality of service (QoS). For the QoS support and service differentiation it is important that the admission control and packet scheduling functionalities are QoS-aware. In this paper a combined admission control and a decoupled time-frequency domain scheduling framework for LTE uplink is presented. The proposed framework is shown to effectively differentiate QoS user classes in a mixed traffic scenario.
