    Abstract: Provided is a method for receiving a downlink control channel in a machine type communication (MTC) device. A method for receiving a downlink control channel can comprise the steps of: receiving first configuration information about an MTC device-operable subband among system bands of a cell; receiving second configuration information, about a subframe, for monitoring a downlink control channel in a cell-specific search space (CSS); and switching from a subband with respect to the first configuration information to a pre-configured cell-common subband and then receiving, in the cell-common subband in a subframe with respect to the second configuration information, a downlink control channel in the CSS and another channel.

    Abstract: The disclosure of the present specification provides a method for receiving a physical downlink shared channel (PDSCH) on a low-capability (LC) or low-cost (LC) device. The method may comprise the steps of: receiving repetition of a downlink control channel in the case that the LC device is set to coverage enhancement (CE); determining a last subframe where the reception is terminated; and determining a start subframe for receiving the repetition of the PDSCH on the basis of the last subframe. The reception of the PDSCH starts at the k-th effective subframe after subframe n, and the subframe n may be the last subframe where the reception of the downlink control channel is terminated. K is greater than or equal to 2, and the effective subframe may be predetermined.

    Abstract: A method for controlling uplink transmit power of a user equipment (UE) in a radio access system supporting a multi-connectivity mode is discussed. The method performed by the UE includes receiving a higher layer signal including first power parameters of a first serving cell from the first serving cell and a higher layer signal including first power parameters of a second serving cell from the second serving cell, receiving a physical downlink control channel (PDCCH) including second power parameters of the first serving cell from the first serving cell and a PDCCH including second power parameters of the second serving cell from the second serving cell, measuring two path loss values of the first and the second serving cells, respectively, calculating a physical uplink control channel (PUCCH) transmit power for the first serving cell and a PUCCH transmit power for the second serving cell in the multi-connectivity mode, and transmitting a PUCCH to the first serving cell based on the PUCCH transmit power for the first serving cell and a PUCCH to the second serving cell based on the PUCCH transmit power for the second serving cell.
