Abstract: The present description provides a method for transmitting a scheduling request (SR) in a low-capability (LC) or low-cost (LC) device. The method can comprise a step for receiving an upper layer signal comprising an SR subframe offset and an SR transmission period. The upper layer signal can further comprise information about the number of repetitions. Also, the method can comprise the steps of: determining, on the basis of the SR transmission period and SR subframe offset, a subframe on which the SR is to be transmitted; determining the number of repeated transmissions of the SR on the basis of the information; and transmitting the SR on the determined subframe. The SR can repeatedly be transmitted on a plurality of subframes that begin from the determined subframe.

Abstract: According to the present invention, a base station transmits zero-power information with respect to a downlink control channel, sets some of downlink control channel candidates in a slot at zero-power in accordance with the zero-power information, and transmits the downlink control channel via the downlink control channel candidates User equipment receives the zero-power information with respect to the downlink control channel and receives the downlink control channel via the downlink control channel candidates in the slot. The user equipment detects the downlink control channel by assuming, on the basis of the zero-power information, that the some of downlink control channel candidates are zero-power.

Abstract: A method and apparatus for communicating with a machine-type communication (MTC) user equipment (UE) in a wireless communication system is provided. A base station (BS) configures a first MTC transmission time interval (M-TTI) for a first UE and a second M-TTI for a second UE in a subband, and communicates with the first UE and the second UE in the subband by using the first M-TTI and the second M-TTI. In this case, the first UE and the second UE have different coverage enhancement (CE) level from each other.

Abstract: For supporting a new radio access technology (new RAT, or NR), a frame structure for the new RAT may be configured. A network node configures a frame in which a first cyclic prefix (CP) is allocated to a first symbol in every 0.5 ms and a second CP is allocated to remaining symbols in every 0.5 ms. In this case, a length of the first CP is longer than a length of the second CP.
