Latest Patents

Xiangnan Liu holds a patent for a "Bandwidth part (BWP) and power scheduling method and apparatus for indoor terahertz." This invention addresses the limitations of terahertz waves in indoor settings by utilizing an intelligent reflecting surface (IRS) and non-orthogonal multiple access (NOMA). The method transforms the indoor environment into a channel model suitable for IRS-assisted terahertz propagation. It also optimizes wireless resource scheduling through functional optimization design with random constraints. The scheduling policies and actions are trained using proximal policy optimization (PPO), where the actor part generates continuous power scheduling, and the critic part produces discrete BWP scheduling.
