In this paper, we present simulative performance analysis of Hybrid Automatic Repeat reQuest (ARQ) with adaptive rate Reed-Solomon (RS) code under delayed Channel State Information (CSI) at the transmitter over inter-HAP (High Altitude Platform) FSO fading channel. The combined effect of atmospheric turbulence and temporal behaviour of the channel were investigated. The performance analysis is determined in terms of Transmission Efficiency (TE) via event based simulations. The results enable us to analyse the benefit of adaptive rate HARQ in presence of delayed CSI so as to maximize the transmission efficiency.
