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.

Abstract: The present invention provides an HARQ-ACK feedback method and device. User equipment of the present invention detects downlink grant downlink control information and performs HARQ-ACK feedback for downlink data corresponding to the downlink control information. The user equipment processes HARQ-ACK for downlink data as a discontinuous transmission (DTX), when there is interference or noise exceeding a threshold value in the downlink data. Therefore, the user equipment can be prevented from receiving the downlink data having a different redundancy version.

Abstract: The present invention relates to a radio access system that supports an unlicensed band, and provides methods for controlling a contention window size (CWS) for performing uplink LBT, methods for effectively utilizing a radio resource even when an uplink data transmission fails, and apparatuses supporting the same. As an embodiment of the present invention, a method for controlling a contention window size (CWS) for transmitting uplink data in a radio access system supporting an unlicensed band by a user equipment, may comprise the steps of: receiving, from an evolved node B, a radio signal including CSW control information indicating information required for controlling a CWS; controlling the CWS on the basis of the CWS control information; performing a listen before talk (LBT) process using the controlled CWS; and transmitting uplink data when a result of the LBT process shows that an unlicensed band is in an idle state.

Abstract: A method and apparatus for controlling an uplink power in a wireless communication system is provided. A user equipment (UE) allocates a first minimum reserved power for a first carrier group and a second minimum reserved power for a second carrier group, and after allocating the first minimum reserved power and the second minimum power, applies a power sharing rule for remaining power, except the first minimum reserved power and the second minimum reserved power, between the first carrier group and the second carrier group.
