Abstract

Reconfigurable intelligent surface (RIS) is a novel hardware technique that can build a programmable wireless environment with passive reflecting elements. RIS can enhance spectral efficiency (SE) and energy efficiency (EE) by imposing phase shifts to the signal. This paper discusses well-defined RIS-assisted system models with corresponding optimization techniques. We investigate two uplink scenarios: communication with a line-of-Sight path and communication without a line-of-sight path. Each system model uses block coordinate descent (BCD) and alternating direction method of multipliers (ADMM), respectively, in optimizing system performance.
