Rate-Splitting Multiple Access for Short-Packet Uplink Communications: A Finite Blocklength Analysis
Jiawei Xu, Onur Dizdar, Bruno Clerckx
Abstract
In this letter, we investigate the performance of Rate-Splitting Multiple Access (RSMA) for an uplink communication system with finite blocklegnth (FBL). Considering a two-user Single-Input Single-Output (SISO) Multiple Access Channel (MAC), we study the impact of blocklength and target rate on the throughput and error probability performance of RSMA where one user message is split. We demonstrate that RSMA can outperform Non-Orthogonal Multiple Access (NOMA) in terms of throughput and error probability performance.
