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.

Abstract: A UE can perform first uplink transmission on the basis of a first scheduling message without NDI, receive a second scheduling message including an NDI field, and perform i) retransmission for the first uplink transmission or ii) new uplink transmission on the basis of the NDI field in the second scheduling message. Performing the retransmission for the first uplink transmission or the new uplink transmission can comprise: determining, in a state in which an NDI value for the first scheduling message is considered a specific value, whether the value of the NDI field is toggled in comparison to the specific value; performing the retransmission for the first uplink transmission on the basis of the non-toggling of the value of the NDI field in comparison to the specific value; and performing the new uplink transmission on the basis of the toggling of the value of the NDI field in comparison to the specific value.
