Sparse code multiple access (SCMA) is a promising technique of non-orthogonal multiple access technology (NOMA). SCMA has the potential to increase the Total Sum Rate (TSR) in 5G systems. Previous works have considered the Fixed and Dynamic resource allocation based on columns (user) criterion. In this paper, we propose resource allocation based on rows (subcarriers). The numerical results show that our approach improves the TSR in an SCMA uplink channel.

按行划分的子载波分配对 SCMA 系统总和速率的影响

稀疏码多址（SCMA）是一种很有前途的非正交多址技术（NOMA）。SCMA 有可能提高 5G 系统中的总和速率 (TSR)。以前的工作已经考虑了基于列（用户）标准的固定和动态资源分配。在本文中，我们提出了基于行（子载波）的资源分配。数值结果表明，我们的方法提高了 SCMA 上行链路信道中的 TSR。
