Abstract: A method for a user equipment (UE) in a wireless communication system includes monitoring a physical channel carrying downlink control information (DCI); and receiving, based on the DCI, downlink data in an unlicensed band cell (Ucell). Further, the downlink data is received in a 1st subframe of a downlink transmission burst, based on being configured to monitor the physical channel on the Ucell, the downlink data is received starting in one of a partial subframe or a normal subframe in the 1st subframe, and the partial subframe is smaller than the normal subframe.

Abstract: Provided are a method for a terminal transmitting an uplink control channel in a wireless communication system, and a device using same. The method comprises: determining the overlapping or not between a first physical uplink control channel (PUCCH) and a second PUCCH; and determining a transmission method for the first PUCCH and the second PUCCH on the basis of the determining. Here, the first PUCCH is an uplink control channel that is frequency division multiplexed (FDM) with a data channel, and the second PUCCH is an uplink control channel that is time division multiplexed (TDM) with the data channel.

Abstract: A method for managing a radio link in an unlicensed band is provided. An apparatus attempts to receive a discovery reference signal (DRS) in a serving cell that is operated in the unlicensed band. The apparatus determines that a radio link to the serving cell has failed if the DRS is not received for a predetermined time.

Abstract: Provided are a method of adjusting uplink timing in a wireless communication system and an apparatus therefor. Specifically, a method for a user equipment to adjust uplink timing in a wireless communication system includes transmitting, to a base station, an uplink signal, receiving, from the base station, a timing advance (TA) command configured based on the uplink signal, and performing uplink transmission to the base station by applying a timing advance (TA) indicated by the TA command. The TA command may be interpreted based on subcarrier spacing of at least one frequency resource region to which the TA is to be applied.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.
