Abstract:
1. A method in a wireless communication system, the method comprising: receiving, by a terminal, a first message including a first uplink/downlink (UL/DL) configuration for a primary cell (PCell) from a base station; receiving, by the terminal, a second message including a second UL/DL configuration for a secondary cell (SCell) from the base station; receiving, by the terminal, a physical downlink shared channel (PDSCH) on a first subframe of the SCell from the base station; and transmitting, by the terminal, a hybrid automatic repeat request-acknowledge (HARQ-ACK) corresponding to the PDSCH on a second subframe to the base station, wherein the second subframe is determined based on a scheduling type for the terminal and a relationship between the first UL/DL configuration and the second UL/DL configuration, if the first UL/DL configuration is different from the second UL/DL configuration.
