Rate-splitting multiple access (RSMA) has emerged as a flexible downlink framework for managing multiuser interference through common and private message splitting. However, in high-mobility scenarios, Doppler-induced intercarrier interference degrades RSMA-based transmission and motivates integration with a transform-...

This paper focuses on physical-layer security against passive eavesdroppers in 6G integrated sensing and communication (ISAC) networks. It proposes an active reconfigurable intelligent surface (RIS)-aided secure-ISAC joint optimization framework, which utilizes the active RIS to overcome the multiplicative-fading bottl...

This paper investigates a robust and secure beamforming scheme for a reconfigurable intelligent surface (RIS) assisted integrated sensing and communication (ISAC) system, employing rate-splitting multiple access (RSMA). In the presence of a potential eavesdropper, the system aims to provide high-quality communication s...

This paper investigates a stacked intelligent metasurface (SIM)-enabled spatial domain index modulation framework. We propose a phase-regulated SIM-enabled spatial domain index modulation (SIM-SDIM) scheme, where spatial bits are mapped onto programmable phase-state combinations of multiple SIM layers. The cascaded SIM...
