Title: METHOD FOR TRANSMITTING OR RECEIVING DOWNLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME
Abstract:
A method for receiving downlink control information by a terminal in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving control channel element (CCE) configuration information from a base station; determining multiple control channel candidates, each of which has one or more CCEs, on the basis of the CCE configuration information; and blind-detecting downlink control information through the multiple control channel candidates, wherein: each of the one or more CCEs comprises multiple resource element groups (REGs), and the number of data resource elements (REs) for carrying the downlink control information is independently determined for each REG; and the CCE configuration information indicates whether each CCE has a fixed number of REGs or a fixed number of data REs.
