Abstract

The present embodiments relate to a method for transmitting and receiving control information and data between a terminal and a base station in a short TTI frame structure. In one embodiment, a search space of a legacy PDCCH and a search space of a sPDCCH are separated from each other on the basis of the type of the search space or aggregation level, etc., and information on the separated search space is signaled to the terminal, thereby enabling the terminal to detect a DCI while reducing the complexity of a blind decoding.
