Abstract: A method and device for receiving a signal in a wireless communication system to which a multiplex transmission technique is applied are provided. The wireless communication system proposed herein suggests a method for increasing the receipt reliability of a terminal with respect to a multiplex transmission activation indicator indicating the start of multiplex transmission. Particularly, a terminal checks the receipt of a multiplex transmission activation indicator transmitted, from a first base station, for every predetermined subframe. If the terminal succeeds in receiving the multiplex transmission activation indicator, an ACK signal associated with the multiplex transmission activation indicator is transmitted to the first base station. Here, the multiplex transmission activation indicator indicates that the first base station and a second base station are capable of transmitting the same data for a predetermined time together.

Abstract: A method of performing a measurement when a mobile terminal is configured with a plurality of component carriers is discussed. The method is performed by the mobile terminal and includes receiving, by the mobile terminal, configuration information from a base station; and performing, by the mobile terminal, the measurement based on the received configuration information. Further, when the received configuration information includes an indication information for the measurement in an extension component carrier among the plurality of component carriers, the measurement in the extension component carrier is based on a channel state information reference signal (CSI-RS), and when the received configuration information does not include the indication information for the measurement in the extension component carrier among the plurality of component carriers, the measurement in the extension component carrier is based on a cell specific reference signal (CRS).
