title = "Opportunistic scheduling for heterogeneous services in downlink OFDMA system",
abstract = "We consider opportunistic scheduling in a downlink OFDMA system to support heterogeneous services. Given the user's queue state information (QSI) and channel state information (CSI), the proposed sum waiting time based scheduling (SWBS) algorithm can guarantee QoS requirements for both real-time (RT) and non-real-time (NRT) service. The benefit is attained from scheduling heterogeneous services based on sum packet waiting time to fulfill the QoS requirements and exploiting multiuser diversity to achieve effective resource utilization. Simulation results illustrate that the max packet loss ratio and packet delay for real-time service and the throughput for non-real-time service are improved by the proposed algorithm.",
