    Abstract: A method for receiving a PDCCH signal by a terminal in a wireless communication system according to one embodiment of the present invention may comprise the steps of: determining the number of CCEs for channel estimation and the number of times of blind-decoding related to multiple search space sets that the terminal needs to monitor during one slot; when the determined number of times of the blind-decoding exceeds a blind-decoding limit or the determined number of the CCEs exceeds a channel estimation limit, dropping at least one PDCCH candidate among PDCCH candidates included in the multiple search space sets; and attempting to detect a PDCCH signal on the basis of remaining PDCCH candidates which have not been dropped among the PDCCH candidates, wherein, in the dropping of the at least one PDCCH candidate, the terminal switches between the multiple search space sets in a round-robin scheme while dropping the at least one PDCCH candidate until both the blind-decoding limit and the channel estimation limit are reached.

    Abstract: The present disclosure provides a method of receiving a physical downlink shared channel (PDSCH) by a user equipment (UE) in a wireless communication system. The method includes receiving first information related to a PDSCH time-domain resource assignment table including a plurality of candidate PDSCH time-domain resource assignment information for PDSCH scheduling, receiving second information related to a minimum offset value for an interval between a slot in which a physical downlink control channel (PDCCH) is received and a slot to which a PDSCH is allocated, and receiving the PDSCH based on candidate PDSCH time-domain resource assignment information including an offset value equal to or larger than the minimum offset value among the plurality of candidate PDSCH time-domain resource assignment information. The PDSCH is received based on one of the plurality of candidate PDSCH time-domain resource assignment information irrespective of the minimum offset value, based on a PDCCH for scheduling the PDSCH, being related to system information (SI), a random access response (RAR), or paging.
