Abstract:
A method of user equipment (UE) for channel state information (CSI) feedback in a wireless communication system. The method comprises receiving, from a base station (BS), CSI feedback configuration information for a pre-coding matrix indicator (PMI) feedback indicating a linear combination (LC) pre-coding matrix that corresponds to a linear combination of a plurality of L beams and a plurality of coefficients, determining the first PMI (i 1 ) and the second PMI (i 2 ), and transmitting, to the BS, the CSI feedback including the first PMI (i 1 ) and the second PMI (i 2 ) over an uplink channel.
