Abstract: A method for receiving an Enhanced Physical Downlink Control Channel (EPDCCH) from a base station by a user equipment (UE) in a wireless communication system. The UE receives a first EPDCCH for a first carrier by monitoring first EPDCCH candidates for the first carrier in a specific physical resource block (PRB) pair set. The UE receives a second EPDCCH for a second carrier by monitoring second EPDCCH candidates for the second carrier in the specific PRB pair set. A position of the second EPDCCH candidates is determined by applying an offset value for the second EPDCCH candidates into a position of the first EPDCCH candidate. The offset value for the second EPDCCH candidates is determined based on a carrier indicator field of the second carrier.

Abstract: One disclosure of the present specification provides a method by which a long term evolution advanced (LTE-A)-based base station transmits data on an unlicensed band. The method can comprise the steps of: setting, by the base station, a listen before talk (LBT) configuration for determining whether to transmit signals of other nodes before transmitting data on the unlicensed band; measuring, by the base station, interference due to signals from other nodes during a preset measurement period; comparing the detected interference and a preset threshold value; changing the LBT configuration according to the comparison; and transmitting the changed LBT configuration to a terminal.

Abstract: The present invention relates to a method and apparatus for aggregating carriers in wireless communication systems. In the method, a first carrier is set up, and a second carrier is added in addition to the first carrier. In addition, the first carrier is a time division duplex (TDD) carrier for which an uplink subframe and a downlink subframe are positioned at different times in a frame, and the second carrier is a carrier only for a downlink that consists of downlink subframes.
