Title:
METHOD FOR RECEIVING OR TRANSMITTING DOWNLINK CONTROL SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/084625
Kind Code:
A1
Abstract:
The present invention relates to a method for receiving a downlink control signal in a wireless communication system according to one embodiment of the present invention, including the steps of: receiving an enhanced physical downlink control channel (EPDCCH) from a downlink serving base station; and monitoring a plurality of EPDCCH candidates in an EPDCCH set in the received EPDCCH, wherein the EPDCCH candidates include candidates for a first component carrier and a second component carrier, the candidates for the first component carrier and second component carrier are alternately positioned according to a specific ratio in each aggregation level L in the EPDCCH set, the specific ratio is a ratio of the number of the candidates for the first component carrier to the number of the candidates for the second component carrier, and the number of the candidates for the first component carrier is equal to or greater than the number of the candidates for the second component carrier.
