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.

Abstract: Provided are a method and apparatus for transmitting data in an unlicensed band. The device determines a downlink reception end time and an uplink transmission start time at which the uplink transmission starts in the unlicensed band. If the interval between the downlink reception end time and the uplink transmission start time is equal to or less than a threshold value, the device abandons the uplink transmission.

Abstract: A disclosure of the present specification provides a method for executing power control by a user equipment (UE). The method may include the steps of: determining a first amount of power for transmitting a first uplink control information (UCI) by a user equipment (UE) set to have a dual connectivity with a first cell group and a second cell group; and determining a second amount of power for transmitting a second UCI. Herein, when the first UCI includes HARQ-ACK but the second UCI does not include HARQ-ACK, the determination of the first amount of power may have a priority over the determination of the second amount of power.

Abstract: Provided are a method and an apparatus for transmitting downlink control information in a wireless communication system configured with a plurality of serving cells. The method generates downlink control information scheduling frequency division duplex (FDD) cells by means of FDD frames (DCI_FDD) and downlink control information scheduling time division duplex (TDD) cells by means of TDD frames (DCI_TDD), and transmits the DCI_FDD and the DCI_TDD, wherein parts of the fields of DCI_FDD and DCI_TDD are generated to have equal bit sizes, and if the FDD or TDD cell is used exclusively, then said parts of the fields in the FDD and TDD cells have mutually different bit sizes.
