1. A method in a user equipment of reporting multi-beam channel state information, CSI, in uplink control information, UCI, the method including:
performing a first transmission in the UCI, the first transmission indicating a plurality of beam index pairs, (lk,mk), each beam index pair corresponding to a beam k; and
performing a second transmission in the UCI, the second transmission indicating at least one of a beam power, a beam rotation and a channel quality index, CQI.
