1. A method of receiving a physical downlink control channel (PDCCH) through a search space (SS) set by a user equipment (UE) in a wireless communication system, the method comprising:
transmitting capability information related to a number of X slots and a number of at least one Y slot for PDCCH monitoring; and
receiving a first PDCCH through a UE-specific SS (USS) set within the at least one Y slot, based on the capability information,
wherein the at least one Y slot is included in the X slots, and X and Y are positive integers,
wherein a monitoring periodicity of the USS set is an integer multiple of a length of the X slots, and
wherein a number of monitored PDCCH candidates and a number of non-overlapped control channel elements (CCEs) are determined based on all search space sets within the X slots.
