WebDec 9, 2024 · 5G NR standard supports both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes in massive MIMO systems. For a reasonably pure estimate, it is necessary to make sure that each pilot transmission in a cell occurs in a vacuum, i.e., free from the interference of other pilots in the same time or frequency. Webwireless technologies, the Massive MIMO brought great energy efficiency and emission spectral effi-ciency gain. So the massive MIMO technology is a revolutionary technology of the 5G communication in the future[2-3]. In this paper, we recommend a TDD model for the massive MIMO system.
