Abstract

This paper considers an opportunistic packet scheduling algorithm to support both RT and NRT service in mobile broadband wireless access system. The design objective of our proposed packet scheduler is to determine the optimal number of RT and NRT users based on the service charges (which differ depending on the type of services) in order to maximize the revenue, while at the same time satisfying their individual QoS requirements, i.e., the maximum allowable packet loss rate for RT traffic and the minimum reserved bit rate for NRT traffic. It takes an urgency of RT users into account only when their head-of-line (HOL) packet delays exceed the given threshold, which allows for maximizing the system capacity of NRT users. Evaluating the proposed approach in orthogonal frequency division multiple access/frequency division duplex (OFDMA/FDD)-based mobile access system, it has been shown that, in terms of the number of RT and NRT service users, system capacity can be significantly improved.
