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: Disclosed herein are a method and apparatus for sending and receiving data in a wireless communication system. More specifically, a method for sending and receiving, by UE, data in an unlicensed band in a wireless communication system may include performing blind detection for detecting a predetermined specific signal transmitted by an eNB in a cell of an unlicensed band and determining a period in which the signal is detected through the blind detection to be a reserved resource period (RRP) which is a time period secured for the transmission and reception of data in the cell of the unlicensed band.

Abstract: In the present invention, a part of a first demodulation reference signal sequence generated on the basis of a basic subcarrier interval (hereinafter, a first subcarrier interval) is used for a second subcarrier interval which is K times the first subcarrier interval. Values selected one for every K from among values constituting the first demodulation reference signal sequence may be used as values constituting a second demodulation reference signal sequence for the second subcarrier interval.

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: The present invention provides: a base station for repeatedly transmitting a physical downlink control channel (PDCCH) during a first subframe bundle comprising a plurality of subframes, and transmitting a PDSCH related to the PDCCH; and user equipment for receiving the PDCCH and the PDSCH. The PDSCH can be transmitted to the user equipment starting from subframe n+k, which is the kth subframe after the last subframe n−1 in the first subframe bundle, wherein k is an integer bigger than 0. The first subframe bundle may begin from a predetermined or fixed position.
