Abstract: This specification provides a long PUCCH using multiple slots in a wireless communication system. The method is performed by a user equipment and includes receiving first information about a TDD UL-DL slot configuration from a base station, receiving, from the base station, second information including a first parameter for a number of slots used for a transmission of the long PUCCH and a second parameter for a duration of a PUCCH symbol within a PUCCH slot, determining the multiple slots for transmitting the long PUCCH based on the first information and the second information, and transmitting the long PUCCH to the base station over the determined slots.

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 invention relates to a Vehicle-to-X (V2X) operation method performed by a V2X terminal in a wireless communication system. Provided is the method comprising: receiving, from a base station, unicast data and multicast data, and transmitting, to the base station, an acknowledgment (ACK)/negative acknowledgement (NACK) for the unicast data and ACK/NACK for the multicast data, wherein the unicast data is data for the V2X terminal and the multicast data is data for a plurality of V2X terminals comprising the V2X terminal.

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.
