Claim 15:
16. A wireless communication device for decoding signaling from a network node indicating which precoders in a codebook are restricted from being used, the wireless communication device comprising:
a processor and a memory, the memory containing instructions executable by the processor whereby the wireless communication device is configured to:
receive codebook subset restriction signaling that, for each of one or more groups of precoders, jointly restricts the precoders in the group across all ranks that include the restricted precoder by restricting a certain component that the precoders in the group have in common; and
decode the received codebook subset restriction signaling as jointly restricting precoders in each of the one or more groups of precoders.
