Semi-grant-free transmission strategy for satellite communications under imperfect channel conditions

To address the multiple access issue in satellite communication systems under spectrum scarcity, a semi-grant-free (SGF) transmission strategy based on non-orthogonal multiple access (NOMA) was proposed. In this strategy, mobile terminals termed as grant-free (GF) users were equipped with a planar a...
