Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DOWNLINK CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/110993
Kind Code:
A1
Abstract:
Disclosed is a 5G or a pre-5G communication system provided to support a higher data transmission rate than a 4G communication system such as LTE. A method and an apparatus are provided for transmitting and receiving a downlink control channel in a wireless communication system. The method includes transmitting, on a first resource region, a detection signal indicating that a downlink control channel is transmitted; and transmitting a signal of the downlink control channel on a search space related to the first resource region.
