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: One downlink control information DCI may be divided into first DCI and second DCI to be transmitted/received. The first DCI may be transmitted/received within a control region of a first TTI of a first time length. The first DCI may include information about the second DCI in a second TTI of a second time length shorter than the first time length. The first DCI may be transmitted/received using first decoding candidates for transmission of the first DCI among decoding candidates in the search space in the control region of the first TTI. The decoding candidates other than the first decoding candidate among the decoding candidates in the search space may be used for transmission/reception of legacy DCI.
