Abstract ▼ AI-Helper

For the fast access with high reliability, a single grant allows a transmitter to transmit multiple redundant packets with new redundancy information in the time domain without waiting for feedback from a receiver. However, entire redundant packets shall be retransmitted in response to a negative acknowledgment of those redundant packets, which increases the service latency. To reduce a long HARQ RTT due to a number of redundant packets, we propose packet-by-packet parallel processing that achieves lower latency by alleviating the long HARQ RTT of repeated transmission. We also provide a model and analysis for repeated transmission functionality, in terms of the wireless transmission latency with packet-by-packet processing. Numerical analysis and simulation in various network environments show that the proposed algorithm achieves lower latency without trading reliability off.
