1. A method for codebook subset restriction at a user equipment (UE), comprising:
receiving, from a network node, codebook subset restriction (CBSR) signaling for a first component common to precoders in a first group of codebooks, wherein a restriction of the first component maps to a restriction of a second component, and wherein the second component is common to precoders in a second group of codebooks, wherein each second component maps to more than one first component; and
restricting precoders selectable from a codebook in the second group of codebooks based on the second component.
