Abstract: A method for transmitting a first physical downlink control channel (PDCCH) by a base station (BS) in a wireless communication system is discussed. The method includes transmitting first information related to a first uplink-downlink (UL-DL) configuration via a system information block (SIB); transmitting second information related to a second UL-DL configuration via a second PDCCH; and transmitting the first PDCCH during an on-duration time based on the second UL-DL configuration. Further, the on-duration timer is counted based on the first UL-DL configuration.
