Title:
METHOD FOR DETECTING DOWNLINK CONTROL INFORMATION AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/062780
Kind Code:
A1
Abstract:
A method is disclosed for detecting downlink control information. In particular, the method comprises: a step of detecting first downlink control information transmitted from a specific cell; a step of detecting second downlink control information included in a shortened downlink control channel, based on resource information about the shortened downlink control channel included in the first downlink control information, if the first downlink control information is detected; and a step of changing any one of a shortened downlink data channel, a shortened uplink data channel, and transmission/reception timings of ACK/NACK signals, which are set in advance based on the performance of the terminal, if the first downlink control information is not detected.
