Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.

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: 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.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate in only a partial band of the system band of a cell. The method may comprise the steps of: considering the number of physical resource block (PRB) pairs, to which a downlink control channel can be mapped, to be one of 2, 4, and 8; when the considered number of PRB pairs is greater than the number of PRB pairs to which the downlink control channel is actually mapped, determining that the downlink control channel is not included in PRB pairs except the number of PRB pairs to which the downlink control channel is actually mapped; and receiving the downlink control channel in only as many PRB pairs as the number of PRB pairs to which the downlink control channel is actually mapped, on the basis of the determination.
