Abstract: Disclosed is a method for a terminal to receive a downlink signal from a base station in a wireless communication system. Specifically, the present invention may include: a step for acquiring a minimum CSI-RS triggering offset that is applicable to a CSI-RS for aperiodic CSI on the basis of the reception of a minimum applicable slot interval for the scheduling of a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH); a step for receiving, from the base station, downlink control information (DCI) for triggering the aperiodic CSI in a first slot; and a step for receiving the CSI-RS from the base station at a point in time later than the first slot and a second slot that is set on the basis of a CSI-RS triggering offset larger than or equal to the minimum applicable CSI-RS triggering offset.

Abstract: Provided are a method and an apparatus for transmitting grant-free based uplink data in a wireless communication system. Specifically, a terminal receives, from a base station, allocation information for a grant-free uplink resource that is semi-statically allocated. The terminal receives, from the base station, allocation information for a first reference signal used for initial transmission of uplink data and allocation information for a second reference signal used for retransmission of the uplink data. The terminal transmits the uplink data through the grant-free uplink resource by using the first reference signal. If decoding of the uplink data fails, the terminal receives, from the base station, an uplink grant corresponding to the second reference signal. The terminal retransmits the uplink data by using the second reference signal on the basis of the uplink grant. The first reference signal is commonly allocated to the terminal, and the second reference signal is specifically allocated to the terminal.

Abstract: Provided are methods and devices for transmitting/receiving downlink signals in a Wireless communication system. Carrier information is provided to user equipment, the carrier information including cell identifier information which indicates Whether a first cell identifier related to a first carrier operating on one resource block (RB) and a second cell identifier used for a cell-specific reference signal (CRS) on the first carrier are the same or different. If the second cell identifier is the same as the first cell identifier, the user equipment assumes that the number of antenna ports for the CRS on the first carrier is the same as the number of antenna ports for a reference signal defined for NB-IoT (reference signal for NB-IoT, NRS). If the second cell identifier is different from the first cell identifier, the carrier information further includes antenna port number information, and the user equipment assumes that the number of the antenna ports for the CRS is the same as the number of antenna ports based on the antenna port number information.
