Abstract
Various examples with respect to frequency-selective precoding for uplink (UL) transmissions in mobile communications are described. A processor of a user equipment (UE) receives signaling from a network node of a wireless network. The processor then performs a codebook-based UL transmission to the network node with frequency-selective precoding in a subband of a plurality of subbands according to the signaling received from the network. For non-codebook-based UL transmissions, the processor performs a non-codebook-based UL transmission of a beamformed sounding reference signal (SRS) to the network node by determining a precoder and performing frequency-selective precoding on the SRS using the precoder with a size of precoder bundling for the frequency-selective precoding in a frequency domain known by the network node.
