Low-Latency Short-Packet Transmissions: Fixed Length or HARQ? [PDF]

, 2018
We study short-packet communications, subject to latency and reliability constraints, under the premises of limited frequency diversity and no time diversity. The question addressed is whether, and when, hybrid automatic repeat request (HARQ) outperforms
