Abstract: A method by which a terminal receives a downlink control channel in a wireless communication system is disclosed. Particularly, the method monitors candidate physical downlink control channels (PDCCHs) composed of control channel elements (CCEs), the number of which corresponds to an aggregation level, so as to receive a PDCCH, wherein CCEs for candidate PDCCHs of a higher aggregation level include all of the CCEs for candidate PDCCHs of a lower aggregation level, and the CCEs for candidate PDCCHs of the lower aggregation level included in each of the candidate PDCCHs of the higher aggregation level can be determined using a matrix on the basis of the magnitude of the higher aggregation level and the number of the candidate PDCCHs of the higher aggregation level.

Abstract: A method of transmitting an uplink (UL) signal by a user equipment (UE) in a wireless communication system, where the method includes: receiving, through a physical downlink control (PDCCH) signal, downlink control information (DCI) regarding a semi-persistent scheduling (SPS) physical uplink shared channel (PUSCH); and periodically transmitting an SPS PUSCH signal based on the DCI. Periodically transmitting the SPS PUSCH signal based on the DCI includes: in a state in which (i) the SPS PUSCH signal is subslot-based, (ii) a demodulation reference signal (DMRS) pattern field included in the DCI is set to a first value, and (iii) simultaneous transmission of a physical uplink control channel (PUCCH) and the PUSCH is configured for the UE: transmitting uplink control information (UCI) through the SPS PUSCH signal, without simultaneously transmitting a PUCCH signal.
