Abstract: A base station and a user equipment may determine whether to determine a start symbol value representing a start symbol of a physical downlink shared channel (PDSCH) on the basis of a reference point which is different from the start of a slot allocated for the PDSCH of a cell and is based on the subcarrier spacing of the cell and the subcarrier spacing of a scheduling cell for the cell. The base station/user equipment may transmit/receive, through the scheduling cell, the DCI including symbol information on the start symbol value for the PDSCH on the basis of the determination.

Abstract: A method and a device for allowing a terminal to transmit a signal in a wireless communication system, according to one embodiment of the present invention, map first uplink control information (UCI) and second UCI to one specific uplink channel if a resource region for transmitting the first UCI and a resource region for transmitting the second UCI are overlapped in a time domain, and transmit the specific uplink channel. Particularly, the specific uplink channel comprises a first bit payload for the first UCI and a second bit payload for the second UCI, wherein the number of bits of the first bit payload and the number of bits of the second bit payload are determined on the basis of preset ratio information.

Abstract: A method of receiving Downlink (DL) data by a User Equipment (UE) in a wireless communication system. The method includes: receiving information related to a number of repetitions of the DL data which is repeatedly transmitted in (i) at least one first Transmission Time Interval (TTI) included in a first subframe, and in (ii) at least one second TTI included in a second subframe that is after the first subframe; and receiving the DL data based on the number of repetitions of the DL data. If a Transmission Mode (TM) for the first subframe is different from a TM for the second subframe, then the UE does not receive the DL data in the at least one second TTI.
