Abstract: Methods and apparatuses for an operation for a channel state information upsampling in a wireless communication system. A method of BS includes: receiving, from a UE, feedback information including at least one SB level precoder; identifying, based on the at least one SB level precoder, a mapping function to perform an up-sampling operation; performing, based on the mapping function, the up-sampling operation to the at least one SB level precoder; and identifying, based on the up-sampling operation, at least one RB level precoder from the at least one SB level precoder for a precoder gain of the BS.
