Method for transceiving downlink control channel in wireless communication system and apparatus therefor
First Claim
1. A method for allowing a user equipment (UE) to receive a downlink control channel in a wireless communication system, the method comprising:
- receiving an EPDCCH (Enhanced Physical Downlink Control CHannel) configuration including resource mapping parameters for an EPDCCH via an RRC (Radio Resource Control) signaling,wherein if the EPDCCH configuration is associated with a multiple point transmission, a starting OFDM (Orthogonal Frequency Division Multiplexing) symbol for the EPDCCH is set as a starting symbol for a PDSCH (Physical Downlink Shared Channel) data transmission related with the multiple point transmission; and
monitoring a search space to decode the EPDCCH from the starting OFDM symbol in a resource block set for the EPDCCH according to the resource mapping parameters for the EPDCCH.

Abstract
The present invention relates to a method for transceiving a downlink control channel in a wireless communication system and an apparatus therefor. Specifically, a method for transceiving a downlink control channel in a wireless communication system comprises a step of receiving a downlink signal comprising a first downlink control channel (Physical Downlink Control Channel, PDCCH) and a second downlink control channel (Enhanced PDCCH; EPDCCH), wherein a starting symbol index of the second downlink control channel is greater than the final symbol index of the first downlink control channel.
