Abstract: Provided are a method and a device for reporting a power headroom in a wireless communication system. The device receives initial downlink control information (DCI) for physical uplink shard channel (PUSCH) transmission in a first subframe and receives triggering DCI in a second subframe. The device calculates a power headroom on the assumption that the PUSCH transmission is not performed.

Abstract: The present specification provides a method for transmitting multiple uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system.More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, control information related to PUCCH resources for transmitting the multiple UCI, wherein the control information includes information related to a number of REs of the PUCCH resources, information related to a modulation order, and information related to a configured maximum code rate; determining a PUCCH resource for transmitting the multiple UCI by comparing a value obtained by multiplying the configured maximum code rate and the modulation order by the number of REs corresponding to the PUCCH resources indexed in ascending order with a size of a payload for the multiple UCI; and transmitting, to the base station, the multiple UCI on the determined PUCCH resource.

Abstract: The present specification provides a method for performing a physical layer security-based hybrid automatic repeat request (HARQ). The method comprises the steps of: generating a first code comprising information bits for forming data to be transmitted, and non-information bits which are unrelated to the data to be transmitted; generating a second code, having a length which differs from that of the first code, by puncturing the first code; determining locations of the information bits and non-information bits within the second code such that a variance of mutual information for each of the information bits and the non-information bits is maximized; and performing the HARQ by using the second code in which the locations of the information bits and the non-information bits are determined.

Abstract: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: The present invention relates to a wireless communication system, and more particularly, to a method for transceiving data in an unlicensed band and an apparatus for same. In particular, disclosed in the present invention are a method and an apparatus for same, the method comprising: a terminal receiving, from a base station, listen before talk (LBT)-type information and information relating to an uplink data transmission interval during which the data is transmitted from within one subframe; and transmitting the data to the base station only during the uplink data transmission interval from within the one subframe, based on an LBT operation indicated by the LBT-type information, thereby efficiently transceiving data between the terminal and the base station in the unlicensed band.

Abstract: The present invention discloses a method for transmitting or receiving ACK information between a UE and a BS in a wireless communication system and an apparatus for supporting the same. According to one embodiment applicable to the present invention, the UE may transmit a first type channel configured with 1 or 2 symbols and a second type channel configured with 4 or more symbols by configuring a transient period between first type channel transmission and second type channel transmission within a time period corresponding to the second type channel if the first type channel and the second type channel are continuous in a time domain.
