Abstract

The present invention relates to a wireless communication system, and more particularly, to a method for a terminal to transmit and receive control information and/or a response signal in a carrier aggregation-based wireless communication system, and to an apparatus therefor, wherein the method includes the steps of: constituting a first cell group having a PCell; constituting a second cell group having at least one SCell; and carrying out a process for transmitting and receiving specific cell-related control information and/or a response signal. The control information and/or the response signal are transmitted and received on the first cell group or the second cell group in the event the first cell group and the second cell group are managed by the same base station. The control information and/or the response signal are transmitted and received on only the first cell group or the second cell group depending on the type of the control information in the event the first cell group and the second cell group are managed by different base stations.
