Abstract:

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.
