Abstract: An operation method of a terminal in a communication system may comprise: receiving, from a base station, an SPS PDSCH; receiving a first PDSCH from the base station; generating SPS HARQ ACK/NACK information for the SPS PDSCH; generating first HARQ ACK/NACK information for the first PDSCH; and when the SPS HARQ-ACK/NACK information is not transmitted in a first slot and transmission of the SPS HARQ-ACK/NACK information is deferred, transmitting both the SPS HARQ ACK/NACK information and the first HARQ ACK/NACK information in a second slot after the first slot.

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 are methods and apparatuses for supporting BWP-based operations in sidelink communication. An operation method of a first terminal in a communication system includes receiving, from a base station, configuration information of a mapping relationship between an uplink (UL) bandwidth part (BWP) and a sidelink (SL) BWP; when a UL switching operation for the UL BWP is performed, performing an SL switching operation for the SL BWP mapped to the UL BWP based on the mapping relationship without separate signaling indicating execution of the SL switching operation; and performing sidelink communication with a second terminal in a switched SL BWP.

Abstract: An operation method of a first terminal, for synchronized operations according to time-sensitive networking, may comprise: receiving information on a reference time from a base station; obtaining an offset of the first terminal with respect to the reference time or information for deriving the offset, and deriving the offset from the information for deriving the offset; determining a timing at which uplink transmission is performed by reflecting the offset to the reference time; and performing the uplink transmission at the determined timing.

Abstract: An operation method of a receiving terminal in sidelink communications may comprise: receiving one or more transport blocks (TBs) from a transmitting terminal; generating hybrid automatic repeat request (HARQ) responses for code block groups (CBGs) included in each of the one or more TBs; selecting one or more HARQ responses from among the HARQ responses based on priorities; and transmitting the one or more HARQ responses to the transmitting terminal through a physical sidelink feedback channel (PSFCH) resource.

Abstract: A method for indicating preemption in a communication system is disclosed. A method for operating a terminal comprises the steps of: receiving, from a base station, information indicating a first resource area, to which a preemption-capable resource belongs, for transmission of first data; receiving resource allocation information of second data from the base station; performing a monitoring operation for detecting a PI indicating a preempted resource for transmission of the first data in the first resource area, when the first resource area overlaps with a second resource area indicated by the resource allocation information; and performing decoding on the basis of the detected PI. Therefore, the performance of the communication system may be improved.

Abstract: The present invention relates to an uplink control information transmission method and device which can improve channel estimation performance of a base station. A terminal operation method for transmitting uplink control information to a base station, according to an embodiment of the present invention, comprises the steps of: receiving, from the base station, resource location information for transmission of a UCI channel; mapping UCI to at least one symbol on the basis of the resource location information, and mapping a reference signal in consideration of frequency selectivity characteristics and time selectivity characteristics of a wireless channel; and transmitting, to the base station, a subframe including the at least one symbol.
