Abstract
A simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) aided communication system is investigated, where an access point sends information to multiple users located on both sides of the STARRIS. Different from prior works which assume that the phase-shift coefficients for transmission and reflection signals can be independently adjusted, a coupled transmission and reflection phase-shift model is considered. Based on this model, a fast beam splitting (FBS) technique is proposed for STAR-RISs to split signals into a multiple beams. Exploiting the FBS technique, the number of split beams can be controlled by using STAR-RIS with one-bit phase shifters and by reconfiguring only a small portion of its elements.
