Abstract
A method of a base station (BS) in a wireless communication system is provided, The method comprises: receiving, from a user equipment (UE), a 1layer sounding reference signal (SRS); arranging the 1layer SRS based on two antenna polarizations of an antenna system of the BS; identifying a dominant direction of a channel based on the 1layer SRS; identifying a coefficient between two antenna polarizations based on the 1layer SRS; constructing a 2-layer channel matrix based on the identified dominant direction and the identified coefficient; and transmitting, to the UE, a downlink signal via the antenna system based on the constructed 2-layer channel matrix.
