Abstract: An operation method of a source terminal for sidelink communication comprises transmitting at least two transport blocks (TBs) or code block groups (CBGs) to a destination terminal, and receiving hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK) bits for the at least two TBs or CBGs from the destination terminal. The operation method further comprises generating an HARQ codebook based on the HARQ-ACK/NACK bits, and reporting the generated HARQ codebook to a serving base station.

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.

Abstract: Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.
