Abstract: A method for transmitting and receiving signals for ultra reliable low latency communication. A method of operating a terminal includes: receiving, from a base station, first DCI including resource allocation information of a first PDSCH; performing a blind decoding operation on a PDCCH candidate when a resource region of the first PDSCH indicated by the first DCI overlaps with a resource region of the PDCCH candidate; and performing a receiving operation of a downlink channel on the basis of a result of the blind decoding operation. Therefore, the performance of a communication system can be improved.
