Digital twin-aided prescreening for user scheduling in MU-MIMO downlink systems

US & West ·

A digital-twin-aided framework DiTUS is proposed to prescreen promising users before instantaneous CSI acquisition. It uses DT-inferred departure angles and path powers to form spatial covariances, optionally calibrated with Gaussian processes, and applies low-complexity rules DiTUS-P and DiTUS-L.

Why it matters

Improves user scheduling efficiency in dense MU-MIMO networks, enhancing multiuser diversity without additional channel estimation overhead.
