Abstract: A method and apparatus for receiving a downlink message in a wireless communication system is provided. A user equipment (UE) receives scheduling information for a downlink message via a dedicated common search space (D-CSS) in a first narrowband from a network, and receives the downlink message in the second narrowband from the network. The D-CSS may schedule resources for random access response (RAR)/Msg4 and initial configuration of UE-specific configurations before UE-specific narrowband (NB) is configured. CSS in UE-specific NB may schedule resources for RAR/Msg4/paging and reconfiguration of UE-specific configurations after UE-specific NB is configured.

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.
