DOI: 10.1109/tvt.2020.3006262
Abstract: Grant-free Non-Orthogonal Multiple Access (NOMA) is a promising solution to enable massive wireless access service for 5G systems and beyond. Conventional grant-free NOMA schemes directly apply the spreading signatures optimized for the grant-based scenarios, which,… read more here.
