Rate-Splitting Multiple Access for RIS-Enabled Full-Duplex Communications with User Relaying

Rate splitting multiple access (RSMA) has emerged as a promising non-orthogonal transmission mechanism to improve spectral- and energy efficiency, and user fairness in multi-antenna broadband channels. To further enhance its performance, in this paper we investigate a novel cooperative RSMA (C-RSMA) transmission framew...

Achievable Rate Lower Bound and Bottleneck Analysis for IRS-Assisted MISO Systems With Channel Estimation Errors

Intelligent reflecting surfaces (IRSs) have attracted extensive research interest for their passive beamforming gains. However, practical IRS-assisted systems rely heavily on accurate channel state information (CSI), which inevitably suffers from estimation errors. Motivated by this challenge, we first investigate the...
