Abstract: An uplink transmission method performed by a terminal includes: receiving, from a base station, at least one DCI for allocating first uplink transmission and second uplink transmission; performing a first LBT procedure for the first uplink transmission, and performing the first uplink transmission when the first LBT procedure is successful; and performing a second LBT procedure for the second uplink transmission, and performing the second uplink transmission when the second LBT procedure is successful, wherein the first uplink transmission and the second uplink transmission are consecutively performed with a time interval longer than a predetermined time.

Abstract: Disclosed are a method and an apparatus for a URLLC in an unlicensed band. An operation method of a terminal comprises the steps of: receiving, from a base station, first configuration information of first FFPs for channel access of the terminal and second configuration information of second FFPs for channel access of the base station; initiating a first COT in at least one first FFP among the first FFPs indicated by the first configuration information; and determining, according to a pre-defined rule, one COT between the first COT and a second COT which is initiated by the base station in at least one second FFP among the second FFPs.

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.
