Advanced mobile communication systems have adopted the adaptive modulation and coding technique because it enables efficient use of the scarce radio resources. The resultant time‐varying resource environment, however, is challenging for guaranteeing quality of service to fixed rate traffic with hard delay constraints such as voice. A fair cut‐off prioritisation scheme that addresses both forced call interruption due to insufficient resources and call unfairness (high disparity between blocking as well as dropping probabilities) due to random propagation conditions is devised. The proposed scheme guarantees full fairness without sacrificing system communication capacity as demonstrated by numerical results. Copyright © 2013 John Wiley & Sons, Ltd.
