METHOD FOR RECEIVING DOWNLINK CONTROL CHANNEL BY MEANS OF A TERMINAL IN A WIRELESS CHANNEL SYSTEM AND APPARATUS FOR SAME

WIPO Patent Application WO/2013/081274

A1

The present invention relates to a method for receiving a downlink control channel by means of a terminal in a wireless channel system and an apparatus for same. In particular, the method for receiving a downlink control channel by means of a terminal in a wireless channel system includes the steps of: dividing at least one resource block allocated to the terminal into the preset number of subsets; selecting one or more subsets for the terminal from the at least one resource block; setting the selected subset set as a search space for the terminal; and performing blind decoding for the search space to detect the downlink control channel, wherein the preset number of subsets are respectively demodulated by demodulation reference signals (DM-RS) defined with different antenna ports in each of the resource blocks.
