Claim of US Patent No. 10,924,242

1. A method of receiving downlink control information (DCI) by a user equipment (UE) in a wireless communication system, the method comprising:performing blind detection for a group common physical downlink control channel (PDCCH) in a common search space (CSS) having a plurality of PDCCH candidates; and
obtaining downlink control information (DCI) indicating a slot format from the blind-detected group common PDCCH,
wherein in the blind detection of the group common PDCCH, the UE selectively attempts to detect the group common PDCCH only at a predetermined position in the CSS having the plurality of PDCCH candidates,
wherein the UE determines a type of each symbol included in a slot based on the slot format indicated by the DCI,
wherein, in a state in which a number of PDCCH candidates at the predetermined position is two or more, the two or more PDCCH candidates for blind detection of the group common PDCCH are contiguous, and
wherein the UE determines the PDCCH candidates at the predetermined position based on information regarding the group common PDCCH that is received through higher layer signaling.
