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 42):
The method of  claim 41 , wherein the first dimension index l\u2032 1  and the second dimension index l\u2032 2  are first and second forbidden dimension indices, respectively, such that the first dimension index l\u2032 1  and the second dimension index l\u2032 2  identify a forbidden two-dimensional beam for which corresponding precoding matrix codewords are not to be reported.
