Abstract: The disclosure relates to a method and apparatus for transmitting and receiving a signal in a wireless communication system. An operating method of a terminal in a wireless communication system includes receiving, from a base station, information related to a position of a symbol in which a synchronization signal block is transmitted in a time domain, determining whether a position of a symbol configured to transmit an uplink signal overlaps the position of the symbol in which the synchronization signal block is transmitted in the time domain, in case that the position of the symbol configured to transmit the uplink signal overlaps the position of the symbol in which the synchronization signal block is transmitted in the time domain, determining whether a time or frequency-division duplexing (XDD)-related indicator is configured or received, and transmitting the uplink signal to the base station, based on a result of the determining whether the XDD-related indicator is configured or received.

Abstract: A method is provided for a terminal, which includes identifying information on a number of slots for PUCCH transmission via an RRC signal; obtaining information on a starting symbol for the PUCCH transmission and information on a PRB for the PUCCH transmission; identifying a slot index for the PUCCH transmission for the PUCCH transmission; and performing, based on the information on the starting symbol, the information on the PRB, and the slot index, the PUCCH transmission in a plurality of slots corresponding to the number of slots. The information on the starting symbol and the information on the PRB are applied to a PUCCH of each of the plurality of slots. The PUCCH of each of the plurality of slots includes at least four symbols. The information on the starting symbol and the information on the PRB are obtained based on a combination of the RRC signal and physical signal.
