Abstract :
This paper suggests a novel delay NAK retransmission scheme for ARQ protocol based on channel state for reliable data transmission in the terrestrial mobile communication systems. The proposed scheme is an improved version of the automatic repeat request defined in the RLP layer of 3GPP2. We analyze the performance of the proposed scheme and some existent retransmission schemes over a two-states Markov channel model with the concept of matrix functions. The performance improvement of the delay NAK retransmission scheme is also verified on computer simulations. It shows that the drastic enhancement of the transmission reliability and reduction of the power consumption at the mobile host can be achieved at the cost of minor increase in complexity.
