Abstract
This paper generalizes the information theoretic achievable rate analysis of time (slot length) adaptive and non- adaptive incremental redundancy (IR) hybrid ARQ (HARQ) of earlier works to bandwidth (fixed slot length) or time x bandwidth adaptive IR HARQ systems operating in a block fading channel. It establishes the relationship between the ´sub-packet´ rates and corresponding slot capacities to guarantee arbitrary reliability and conversely the condition for outage.
