15. A method of a user equipment (UE) a wireless communication system, the method comprising:
receiving information about an antenna system of a base station, the information comprising a number of collocated antenna groups and a number of antenna modules for each type of antenna modules in each of the collocated antenna groups, wherein a collocated antenna group of the collocated antenna groups has at least two types of antenna modules, a first module with first antenna type and a second module with second antenna type;
receiving configuration information for at least one channel state information-reference signal (CSI-RS) resource; and
receiving at least one CSI-RS according to the configuration information and acquiring measurements;
determining a subset of antenna modules based on a comparison between the measurements and a criterion;
generating CSI for the subset of antenna modules; and
transmitting a CSI report comprising the CSI.
