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.

Abstract: A method and apparatus for transmitting a power headroom report (PHR) in a wireless communication system is provided. A user equipment (UE) transmits a first PHR for a first carrier group, which is configured by a first eNodeB (eNB), to a second eNB; and transmitting a second PHR for a second carrier group, which is configured by the second eNB, to the first eNB. The first PHR and the second PHR include a PHR for a physical uplink control channel (PUCCH) regardless of whether simultaneous transmission of the PUCCH and a physical uplink shared channel (PUSCH) is configured or not.

Abstract: A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.

Abstract: The present invention relates to a wireless access system supporting an unlicensed band and provides methods for performing a channel access process for transmitting different types of signals, and devices supporting the same. According to one embodiment of the present invention, a method for transmitting different types of signals in a wireless access system supporting an unlicensed band can comprise the steps of: performing a first channel process (CAP) for transmitting a first type of signal; and transmitting a transmission burst including the first type of signal through the unlicensed band if it is determined that a serving cell (SCell) of the unlicensed band is in an idle state after performing the first CAP. At this time, at least one of first parameters for performing the first CAP can be set to be value less than that of second parameters for performing a second CAP for transmitting a second type of signal.
