Abstract:
A method, in a radio network node, comprises identifying, among a predetermined codebook of precoding matrix codewords, a subset of precoding matrix codewords that are not to be reported by the wireless device ( 90 ) in channel-state-information, CSI, feedback, and transmitting, to the wireless device ( 90 ), a bitmap identifying the subset of precoding matrix codewords that are not to be reported by the wireless device ( 90 ); where each bit in the bitmap corresponds to only one combination of a first dimension index l′ 1  and a second dimension index l′ 2  out of the possible combinations of the first dimension index l′ 1  and the second dimension index l′ 2 , and where the first dimension index l′ 1  and the second dimension index l′ 2  identify a two-dimensional beam, the two-dimensional beam being defined by a vector of complex numbers comprised within at least one column of a precoding matrix codeword in the codebook.

Claim (Index 38):
The method of  claim 33 , wherein each bit of a predetermined value in the bitmap indicates that, for a rank r, any given precoding matrix codeword of the codebook of precoding matrix codewords is not allowed to be reported in CSI feedback if transmissions using the precoding matrix codeword would have at least one spatially multiplexed layer of data on a two-dimensional beam identified by the bit.
