Abstract
A user equipment (UE) receives, from a network node, codebook subset restriction (CBSR) signaling comprising a bitmap. The bitmap comprises a plurality of bits. A bit of the plurality of bits mapped to a first index indicates whether a vector with the first index from a first set of vectors is restricted. Bits of the plurality of bits mapped within a particular window indicate whether a vector with a second index from the second set of vectors is restricted. The UE restricts precoders selectable from a plurality of codebooks based on the restricted vectors.
