Abstract:
Provided are a method for transmitting and receiving control information and data between a user equipment and a base station in a short TTI frame structure. In the method, a search space of a legacy PDCCH and a search space of a sPDCCH may be 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 may be signaled to the user equipment, thereby enabling the user equipment to detect a DCI while reducing the complexity of a blind decoding.
