Abstract: The present specification provides a method for transmitting and receiving downlink control information (DCI) in a wireless communication system supporting narrow band-Internet of things (NB-IoT). Specifically, a terminal monitors at least one first candidate PDCCH in a first search space and at least one second candidate PDCCH in a second search space, wherein the first search space and the second search space may partially or entirely overlap each other on a time axis. Thereafter, the terminal may search for a first DCI in the at least one first candidate PDCCH and a second DCI in the at least one second candidate PDCCH, wherein the sum of the number of the at least one first candidate PDCCH and the number of the at least one second candidate PDCCH may be less than or equal to a specific number.

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.
