Towards a Unified Coding Scheme for 6G

2026-03-24

AI Summary

This work proposes a unified channel coding architecture tailored for 6G communications, addressing the growing need for solutions that simultaneously deliver strong error-correction performance, low computational complexity, and high energy efficiency—requirements unmet by the disjoint LDPC and polar code frameworks adopted in 5G. By integrating quasi-cyclic irregular LDPC codes, polar codes, and list decoding techniques, the proposed design enables rate-adaptive, low-complexity encoding and decoding. Preliminary evaluations across representative 6G scenarios demonstrate that the architecture achieves excellent error-correction capability while maintaining hardware-friendly implementation characteristics, thereby offering a viable pathway toward an efficient and unified 6G channel coding standard.

Abstract

The growing demand for higher data rates necessitates continuous innovations in wireless communication systems, particularly with the emergence of 6G. Channel coding plays a crucial role in this evolution. In 5G systems, rate-adaptive raptor-like quasi-cyclic irregular low-density parity-check codes are used for the data link, while polar codes with successive cancellation list decoding handle short messages on the synchronization channel. However, to meet the stringent requirements of future 6G systems, a versatile and unified coding scheme should be developed - one that offers competitive error-correcting performance alongside low complexity encoding and decoding schemes that enable energy-efficient hardware implementations. This white paper outlines the vision for such a unified coding scheme. We explore various 6G communication scenarios that pose new challenges to channel coding and provide a first analysis of potential solutions.
