    Abstract: A method for performing a power scaling is discussed. The method performed by a user equipment (UE) includes determining, by the UE configured with dual connectivity to a first cell group and a second cell group, a first power for transmitting a first uplink channel on a first subframe toward the first cell group; determining a second power for transmitting a second uplink channel on a second subframe toward the second cell group; and scaling down the second power for transmitting the second uplink channel if a maximum power is exceeded, wherein the first uplink channel includes a first physical random access channel (PRACH), wherein the second uplink channel includes a second PRACH, and wherein the scaling down is performed if the first subframe is overlapped with the second subframe.

    Abstract: Provided are a method whereby a terminal transmits an acknowledgement/not-acknowledgement (ACK/NACK) with a primary cell and a secondary cell aggregated, and a device for supporting the method. The method comprises: receiving data by a downlink subframe of a secondary cell; and transmitting an ACK/NACK for the data by an uplink subframe of a primary cell, wherein: the time interval between the downlink subframe and the uplink subframe is determined by a first hybrid automatic repeat request (HARQ) timing or a second HARQ timing; the first HARQ timing is an HARQ timing which is applied when the primary cell is used alone; and the second HARQ timing is an HARQ timing which is additional to the first HARQ timing.

    Abstract: Provided are a method and an apparatus for performing a HARQ based on a polar code in a wireless communication system. The apparatus transmits multiple first output bits, which are generated from multiple first input bits, to a receiver. Upon receiving a retransmission request, the apparatus generates multiple second output bits from multiple second input bits. The apparatus selects multiple third output bits from among the multiple second output bits, and transmits the selected multiple third output bits to the receiver. Bits, which are encoded differently from the multiple first output bits among the multiple second output bits, are preferentially selected as the multiple third output bits.
