Enhancing 5G Forward Error Correction Codes for URLLC by Spatial Coupling

Résumé

In this paper, we investigate how to relax the tradeoff between reliability and latency in 5G Ultra-Reliable and Low-Latency Communications (URLLC) services. We propose a redesign of the 5G Forward Error Correction (FEC) code to increase its error correction capability for 5G-enabled URLLC use cases. Starting from the base matrix of the 5G standard Low-Density Parity-Check (LDPC) code we construct a spatially coupled base matrix. From this base matrix, a binary spatially coupled parity check matrix is then obtained after a lifting operation based on one of the lifting factors supported by the standard. The results of the simulation demonstrate that the proposing spatially coupled codes allow additional coding gains of up to 0.8 dB under the considerate scenarios.
