Active or Passive STAR-RIS-Assisted ISAC-NOMA: A Unified Approach

This paper investigates a downlink integrated sensing and communication (ISAC) system utilizing non-orthogonal multiple access (NOMA), empowered by an active simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) operating in energy splitting mode. We maximize the communication sum rat...

Joint Precoding and RIS Phase Shift Design for Sum-Rate Maximization in RIS-Aided MISO Symbiotic Radio

Symbiotic radio (SR) has emerged as a spectral-efficient paradigm for Internet-of-Things networks. However, simultaneously optimizing coexisting primary and secondary transmissions remains a challenge. To address this, a joint precoding and RIS phase shift design is proposed to maximize the sum-rate in the reconfigurab...

QoS-Aware Joint Subcarrier and Power Allocation for OFDM-ISAC V2X Systems

This paper investigates joint subcarrier and power allocation for a multi-user Orthogonal Frequency Division Multiplexing (OFDM)-based Integrated Sensing and Communication (ISAC) system in Vehicle-to-Everything (V2X) environments. The goal is to maximize a weighted sum of the capped effective radar Signal-to-Noise Rati...

Joint Beamforming and Phase Shifts Design for RIS-Enabled RSMA-ISAC Systems

This letter investigates the sensing-centric design of reconfigurable intelligent surface (RIS)-enabled rate-splitting multiple access-integrated sensing and communication (RSMA-ISAC) systems. Specifically, we propose a new beam-gain approximation method to enhance the sensing beam gain while satisfying communication q...

Max-min fair multigroup multicast in an IRS-aided MISO system

Simulation results demonstrate the guaranteed convergence and the superiority of the proposed scheme in improving the minimum weighted SINR at the users, as well as the contribution of the IRS in reducing the transmit power consumption and the number of active transmit antennas at the AP.

Power Minimization in Active RIS-Assisted NOMA-MEC Networks

In this letter, we investigate a mobile edge computing (MEC) system enabled by an active reconfigurable intelligent surface (ARIS)-assisted uplink non-orthogonal multiple access (NOMA) transmission. We propose an ARIS-assisted uplink NOMA-MEC scheme, termed as ARIS-NOMA, in which multiple users perform local computatio...
