Abstract
In this letter, we propose a novel method of implementing an opportunistic priority queuing scheme that supports both latency-sensitive real-time (RT) and best-effort non-real-time (NRT) service classes in mobile broadband wireless (MBWA) systems. It employs an adaptive. delay threshold as a dynamic reference of prioritizing the urgent RT service users over others, which allows for fully leveraging the multiuser diversity gain of NRT service users under the varying system conditions. It is shown that the overall system capacity can be further increased by the proposed adaptation rule, as compare wit the existing opportunistic priority queuing scheme with the fixed delay threshold.
