Method for monitoring downlink control channel in wireless communication system, and apparatus therefor

摘要

The present invention relates to a method for monitoring, by a terminal, an enhanced physical downlink control channel (EPDCCH) in a wireless communication system supporting carrier aggregation. In detail, the method includes the steps of receiving monitoring information about a first cell from a base station and a second cell cross-carrier scheduled from the first cell; and monitoring the EPDCCH on the basis of the monitoring information, wherein the monitoring information includes information that the number of EPDCCH candidates on the first cell is reallocated, when the maximum number of enhanced control channel elements (ECCE)) available in a specific EPDCCH set on the first cell does not support the number of the EPDCCH candidates of an aggregation level with respect to the second cell.

主权项

1. A method for monitoring an enhanced physical downlink control channel (EPDCCH), by a user equipment, in a wireless communication system supporting carrier aggregation, the method comprising the steps of:
receiving, from a base station, monitoring information on a first cell and a second cell cross-carrier scheduled from the first cell; and monitoring the EPDCCH on the basis of the monitoring information, wherein the monitoring information includes information that the number of EPDCCH candidates on the first cell is reallocated, when the maximum number of enhanced control channel elements (ECCE) available in a specific EPDCCH set on the first cell does not support the number of the EPDCCH candidates of a special aggregation level related to the second cell.
