Abstract:
Disclosed in the present application is a method for transmitting, by a terminal, an uplink signal to a base station through a plurality of antenna ports in a wireless communication system. Specifically, the method comprises the steps of: transmitting, to the base station, uplink reference signals corresponding to the plurality of antenna ports and antenna port grouping information: receiving, from the base station, information on an uplink precoder, which is determined on the basis of the uplink reference signals and the antenna port group information; precoding the uplink signal using the information on the uplink precoder; and transmitting the precoded uplink signal to the base station, wherein the antenna port grouping information comprises information on antenna port groups comprising the plurality of antenna ports and information of the signal distortion level between the antenna port groups.
