Opportunistic scheduling (OS) is a modern view of communication over fading wireless channels, whereby, unlike rate adaptation based schemes, channel variations are exploited rather than mitigated. This letter proposes an OS scheme with embedded traffic parameters to provide fairness and differentiated QoS to different traffic types. Numerical investigations over Rayleigh fading channels show the throughput superiority of the scheme over round-robin policy while guaranteeing weighted fairness among different traffic classes.
