METHOD AND APPARATUS FOR ACQUIRING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for acquiring control information of a user equipment (UE) in a wireless communication system, comprising:
- receiving Enhanced-Physical Downlink Control Channel (E-PDCCH) configuration information from a base station (BS); and
transmitting an acknowledgement/negative acknowledgment (ACK/NACK) response to the E-PDCCH configuration information,wherein, during a predetermined time after transmission of the ACK/NACK response, the user equipment (UE) performs blind decoding for downlink control information (DCI) in a common search space of a physical downlink control channel (PDCCH) resource region and in a search space of an E-PDCCH resource region.

Abstract
A method for acquiring control information in a wireless communication system according to one embodiment of the present invention includes the steps of: receiving E-PDCCH (Enhanced-Physical Downlink Control Channel) configuration information from a base station (BS); and transmitting a confirmation response for the E-PDCCH configuration information. The terminal performs blind decoding for downlink control information in a common search space on a PDCCH (Physical Downlink Control Channel) resource region and a search space on the E-PDCCH during a predetermined period after transmitting the confirmation response.
