The performance of truncated Chase Combining based Hybrid Automatic Repeat reQuest (CC-HARQ) in multihop relay network is analysed. Different from prior works, composite lognormal shadowed Nakagami fading channels are considered. By extending the Moment Generation Function (MGF) method to approximate the output signal-to-noise ratio to a lognormal random variable, the end-to-end outage probability is derived. The accuracy of the proposed approximating method is validated by simulations and the factors to affect such accuracy are thoroughly studied. The results have lots of potential usage in the analysis and design of practical networks such as power allocation, relay placement and optimization for energy efficiency etc.
