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 method for a user equipment (UE) in a wireless communication system includes monitoring a physical channel carrying downlink control information (DCI); and receiving, based on the DCI, downlink data in an unlicensed band cell (Ucell). Further, the downlink data is received in a 1st subframe of a downlink transmission burst, based on being configured to monitor the physical channel on the Ucell, the downlink data is received starting in one of a partial subframe or a normal subframe in the 1st subframe, and the partial subframe is smaller than the normal subframe.

Abstract: Disclosed are a method for transmitting a physical uplink control channel by a terminal in a wireless communication system and an apparatus supporting the same. As a specific example, a terminal according to an embodiment of the present invention may determine a modulation order to be applied to uplink control information (UCI) to be transmitted, on the basis of a payload size of the UCI, and transmit the UCI, to which the determined modulation order has been applied, via a PUCCH resource. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, a base station or a network.
