Abstract: The present disclosure provides a method for a terminal to receive a physical downlink shared channel (PDSCH) in a wireless communication system supporting a narrow band-internet of things (NB-IoT). Specifically, the terminal receives a first physical downlink control channel (PDCCH) including first downlink control information (DCI) from a base station and receives a first PDSCH on the basis of the first DCI. Here, the first PDSCH may include indication information indicating whether a multi transport block is scheduled. The terminal receives a plurality of PDSCHs from the base station, wherein at least one PDSCH of the plurality of PDSCHs may be received without receiving a separate DCI according to the indication information.
