Résumé: This paper suggests a NAK-based selective repeat (SR) scheme for reliable data transmission in the future land-mobile communications systems supporting multimedia services. The proposed scheme is an improved version of the automatic repeat request defined in IS-707 [3]-[4]. We analyze the proposed SR under the assumption of two-states Markov channel. The numerical results show that drastic performance improvement can be achieved at the cost of minor increase in complexity.
