Method for transmitting and receiving downlink signal in wireless communication system, and device therefor
The present invention relates to a method and a device for receiving a downlink signal by a terminal in a time division duplex (TDD) wireless communication system supporting a wireless resource usage change. Specifically, the present invention comprises the steps of: configuring system information block (SIB)-based uplink-downlink configuration 0 as an uplink (UL) reference configuration; and receiving downlink control information including a first field which defines an uplink (UL) index or a downlink assignment index, wherein the downlink control information is received through a common search space, and the first field is determined as the uplink (UL) index when a downlink control information (DCI) format relating to the DL control information is DCI format 0.
