成果简介	NOVELTY - The method involves using base station (BS) to transmit high-frequency THz signals using MU-MIMO technology to serve multiple users. The Reconfigurable Intelligent Surface (RIS) is deployed to assist the transmission. The RIS element adjusts its phase shifts to maximize signal strength at the user's location. The Users receive direct signals from BS and reflected signals from RIS. The available THz spectrum is divided into multiple subcarriers for efficient multi-user allocation. USE - Method for optimizing Terahertz (THz) OFDMA Multi-user MIMO (MU-MIMO) and Orthogonal Frequency-Division Multiple Access (OFDMA) communication by analyzing peak down rates from 4G to next generation system, i.e 6G network by jointly optimizing beamforming at the base station BS and Reconfigurable Intelligent Surface (RIS). ADVANTAGE - The method enables reducing interference and improving spectral efficiency and serving multiple users simultaneously. The method enhancs spectral efficiency and dividing the same amount of data rate to users, and optimizes phase shifts to enhance signal strength and direction, and provides alternative paths for blocked signals in non-line-of-sight (NLoS) scenarios, thus improving coverage in NLoS scenarios and multi-user signal reception (UE). The method ensures optimal data rate selection based on channel quality, and ensures optimized energy usage per subcarrier. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of the optimizing method. (Drawing includes non-English language text).
