AI Technical Summary
In cellular mobile communications, especially in URLLC communications where low latency is a critical requirement, the latency problem caused by retransmissions has not been effectively solved, and existing technologies struggle to shorten retransmission times.
A two-stage FEC coding scheme is adopted, in which first and second codes are applied for encoding and decoding at the data link layer and the physical layer, respectively. By processing the encoding unit at the data link layer, which is higher than the physical layer, retransmission requests are made, and the retransmission process is optimized by combining ARQ or HARQ mechanisms.
It effectively reduces the occurrence of retransmissions and shortens the retransmission time when necessary, thus achieving low-latency communication.
