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.

A method for detecting downlink control information in a frame structure of a short transmission time interval, the method comprising:
- configuring a search space of a downlink control channel of a first transmission time interval as a first aggregation level;
- and
- configuring a search space of a downlink control channel of a second transmission time interval as a second aggregation level,
- wherein the first aggregation level and the second aggregation level are separated from each other.
A method for detecting downlink control information in a frame structure of a short transmission time interval, the method comprising:
- receiving a downlink control channel of a first transmission time interval configured as a first aggregation level;
- and
- receiving a downlink control channel of a second transmission time interval configured as a second aggregation level;
- wherein the first aggregation level and the second aggregation level are separated from each other.
A user equipment for detecting downlink control information in a frame structure of a short transmission time interval, the user equipment comprising:
- a receiver configured to receive a downlink control channel of a first transmission time interval configured as a first aggregation level and receive a downlink control channel of a second transmission time interval configured as a second aggregation level;
- wherein the first aggregation level and the second aggregation level are separated from each other.
