Long Term Evolution (LTE) is a cellular network that operates completely in packet domain. It can also support multimedia services. Due to this nature, provisioning the Quality of Service (QoS) requirements has become a challenge to the design of scheduler. Especially, the scheduler must guarantee for transmitting the real-time traffics such as VoIP (voice over IP). In this paper, a scheduler that satisfies the different QoS requirements is presented. This scheduler considers the additional QoS consideration to the Proportional Fair (PF), which is a well-known scheduling algorithm. As the core work of this paper, its performance is evaluated by comparing with the existing well-known schedulers. For non-real-time traffics such as file download, the performance of the scheduling scheme is evaluated by comparing with PF scheduler. For real-time traffics such as video live streaming, its performance is compared with Frame Level Scheduler (FLS).Keywords
