In this paper, the authors study a multiple access system without feedback supporting multiple carriers for delay critical applications with a small loss tolerance. In such a system, users transmit R times within the next N timeslots, in order to improve their success probability. In an earlier work, they considered the same problem in a single carrier system and demonstrated that the distribution of properly designed user codes significantly improved the success probability over a random selection strategy.
