Abstract :
The structure and performance of a circuit-switched data transport mechanism that transmits up to 9.6 kb/s asynchronous data over a North American time-division multiple access (TDMA) digital cellular radio channel are described. Options for the radio data link layer protocol are examined. The ARQ protocols examined are derived from the high-level data link control (HDLC) family. The options considered are type-one hybrid ARQ (automatic repeat request) schemes using a HDLC data link layer and Reed-Solomon forward error correction. Asynchronous throughput results obtained using a Rayleigh fading model are presented for different speeds and carrier-to-interference ratios. Simulations indicate that at least 4.8 kb/s throughput is achievable for a 17 dB carrier-to-interference ratio, and performance rapidly approaches the maximum rate of 9.6 kb/s for less interference
