Abstract:
A method performed by a wireless device for transmitting a channel state information (CSI) report for a downlink channel comprises obtaining a first set of candidate frequency-domain components and determining a set of spatial-domain components. The method comprises determining a second set of candidate frequency-domain components as a subset of the first set of candidate frequency-domain components. The method comprises determining, for each spatial-domain component of the set of spatial-domain components, a spatial-domain component-specific set of frequency-domain components as a subset of the second set of candidate frequency-domain components. The method comprises transmitting, to a network node, the CSI report.
