This paper investigates a movable-element simultaneously transmitting and reflecting reconfigurable intelligent surface (ME-STARS) assisted rate-splitting multiple access (RSMA) system under imperfect channel state information (CSI). Unlike conventional STARS with fixed element positions, the elements of ME-STARS can b...

We study a robust multiuser framework for simultaneous wireless information and power transfer (SWIPT), where rate-splitting multiple access (RSMA) is integrated with a movable-element simultaneously transmitting and reflecting surface (ME-STARS). By allowing the STARS elements to change their positions in addition to...

The results show that MMD closely outperforms fixed and random allocation and closely follows the single-user proportional fair (PF) benchmark, while RRH cooperation, frequency diversity, dominant-interferer protection, additional transmit antennas, and larger RIS sizes improve reliability and effective goodput.
