In the S-band mobile interactive multimedia specification, an asynchronous access using Enhanced Spread Spectrum Aloha random access has been defined for occasional messaging applications. This access scheme is complemented by a combined automatic repeat request and terminal rate control mechanism that is described in this paper. Furthermore, a queuing theory-based model is developed to describe the behaviour of the automatic repeat request mechanism, and performance results from the first proof-of-concept implementation are presented.

This paper presents the joint automatic repeat request and terminal rate control mechanism that have been defined for the S-band mobile interactive multimedia standard. A model based on queuing theory is developed to dimension the automatic repeat request parameters and understand the QoS boundaries of S-band mobile interactive multimedia. Furthermore, first experimental results are presented.
