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.

Abstract: Disclosed are various methods for transmitting or receiving data or control information having high reliability conditions. A method for operating a terminal which transmits uplink control information (UCI) includes: a step of generating UCI; a step of comparing the priority of an uplink (UL) control channel for the transmission of the UCI with the priority of a UL data channel when some symbols of the UL control channel and the UL data channel overlap; and a step of selecting the UL channel having a higher priority among the UL control channel and the UL data channel, and transmitting the UCI to a base station through the selected UL channel.
