Abstract: Disclosed are methods and apparatuses for transmitting and receiving data channels in a communication system. An operation method of a terminal in a communication system may comprise receiving, from a base station, resource allocation information of a plurality of physical uplink shared channels (PUSCHs) used for repetitive transmission of a same transport block (TB); identifying a position of each of the plurality of PUSCHs in a time domain based on the resource allocation information; and repeatedly transmitting the same TB to the base station at the position of each of the plurality of PUSCHs. Therefore, performance of the communication system can be improved.

Abstract: A method by which a terminal operating in an unlicensed band transmits a signal includes the steps of: receiving, from a base station, configuration information about a carrier; receiving configuration information for configuring N (where N is an integer) guard band(s) for some frequency domains of the carrier; and transmitting a signal to the base station by using a first frequency domain of a bandwidth part belonging to the carrier, wherein the first frequency domain can be a domain excluding the N guard band(s) from the frequency domain of the bandwidth part.

Abstract: Disclosed are methods and apparatuses for transmitting and receiving control information in a communication system supporting unlicensed band communication. An operation method of a terminal may comprise receiving, from a base station, first configuration information of a CORESET and second configuration information of a search space associated with the CORESET; receiving, from the base station, third configuration information indicating one or more PDCCH monitoring resource sets associated with the CORESET and the search space; and performing a PDCCH monitoring operation on the one or more PDCCH monitoring resource sets. Therefore, the performance of the communication system can be improved.
