In This work we propose a new analytical model of the NAK-based selective repeat (SR) ARQ scheme for packet data services in UMTS systems. We analyze the RLP performance over a pair of Markov channels considering the imperfect feedback and arrive to an adequate formulae for residual FER, data throughput, and expected delay as a function of physical layer FER and normalized Doppler bandwidth. Numerical results show that due to the NAK based mechanism, the initial state distribution of the forward channel makes the channel correlation throughput performance beneficial.
