摘要
Disclosed are a method and a device for transmitting or receiving downlink control information in a wireless communication system. A method for receiving downlink control information (DCI) according to an embodiment of the present disclosure any comprise the steps of: repeatedly receiving the DCI via a plurality of physical downlink control channel (PDCCH) candidates; and transmitting or receiving data scheduled via the DCI. The DCI may be transmitted via a first physical downlink control channel (PDCCH) candidate within a first search space set and a second PDCCH candidate within a second search space set, the first search space set and the second search space set may be related to different transmission configuration indication (TCI) states, and a window that is a duration in which the first PDCCH candidate and the second PDCCH candidate are transmitted may be preconfigured in a time domain.
