Abstract :
This paper proposes a physical layer structure that supports multiple timeslot operation for high speed packet radio services in the existing TDMA based cellular network, such as GSM/DCS1800. Different channel coding and interleaving schemes in combination with automatic retransmission request (FEC+ARQ) have been studied and the complexity of packet mobile terminals is discussed in terms of multiple timeslot operation and physical layer retransmission timing. The calculation methods and formulas of residual frame error rate (RFER), expected packet throughput and delay estimates of the proposed channel coding with ARQ are presented. Based on computer simulation results and using these formulas, we select the suitable combination of FEC+ARQ scheme
