Hop-Aware CSI Fusion for Frequency-Asynchronous SRS in TDD Massive MIMO
Wideband time-division duplexing (TDD) massive multiple-input multiple-output (MIMO) precoding requires channel state information (CSI) that is both frequency-selective and temporally fresh. In practical fifth-generation New Radio networks, uplink sounding reference signal (SRS) resources are often sparsely allocated a...
