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

摘要

The present invention relates to a method for receiving a downlink control channel by a terminal in a wireless communications system and an apparatus for the same. More specifically, the method for receiving the downlink control channel by the terminal in the wireless communications 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 as a search space for the terminal; and performing blind decoding for the search space to detect the downlink control channel. The preset number of the subsets is separately demodulated by demodulation reference signals (DM-RS) defined with different antenna ports in each of the resource blocks.
