Abstract:
A method for receiving, by a terminal, control information in a wireless communication system, according to one embodiment of the present invention, comprises: receiving search space information for a self-contained subframe having all of a downlink control symbol, a data symbol, and an uplink control symbol; determining control channel candidates in the downlink control symbol of the self-contained subframe on the basis of the search space information; and searching for downlink control information of the terminal from the determined control channel candidates, wherein the determined control channel candidates constitute at least two or more search spaces on the downlink control symbol, and the terminal can search for the downlink control information assuming a transmission scheme specific to a search space to which each control channel candidate belongs.
