Abstract: The present disclosure provides a method for transmitting, by a user equipment, feedback information to a base station in a wireless communication system. The method includes receiving, from the base station, information about reference signal port group sets composed of one or more reference signal port groups; selecting at least one reference signal port group set among the reference signal port group sets; under assuming that a specific precoder has applied to the selected at least one reference signal port group set, calculating channel state information (CSI) corresponding to the selected at least one reference signal port group set; and transmitting, to the base station, the feedback information including an indicator indicating the selected at least one reference signal port group set and the channel state information; wherein the one or more reference signal port groups are composed of reference signal ports to which the same precoder is applied.

Abstract: Provided are a method and a device for transmitting a scheduling request in a wireless communication system. Particularly, user equipment receives information on first and second scheduling request resources which is broadcasted from a base station. The user equipment receives information on the first and second scheduling request resources which is transferred specifically to the user equipment from the base station. On the basis of the information, the user equipment selects the first scheduling request resource or the second scheduling request resource. The user equipment transmits a scheduling request via the selected resource.
