Abstract:
1. A method by a base station in a mobile communication system employing time division duplexing, the method comprising: transmitting, to a terminal, first subframe configuration information of a first cell; transmitting, to the terminal, information for activating a second cell, second subframe configuration information of the second cell, and configuration information of cross-carrier scheduling; transmitting, to the terminal, scheduling information on a control channel of the first cell based on the configuration information of cross-carrier scheduling; and transmitting, to the terminal, data on a shared channel of the second cell based on the scheduling information, wherein the scheduling information is transmitted in a downlink subframe or a special subframe based on the first subframe configuration information for the first cell, wherein the data is transmitted in a downlink subframe or a special subframe for the second cell, which corresponds to the downlink subframe or the special subframe for the first cell, and wherein the first subframe configuration information is different from the second subframe configuration information.
