A method performed by a user equipment (UE) is disclosed. The method includes receiving, using a first RAT, first SCI including a first priority value, and receiving, using a second RAT, second SCI including a second priority value. The method also includes determining whether to drop one of a transmission of a first physical channel derived from the first SCI and a transmission of a second physical channel derived from the second SCI based on the first priority value and the second priority value when the first physical channel overlaps the second physical channel in the time domain.
