Abstract: A method performed by a first user equipment includes identifying sidelink (SL) resource pool information, determining whether a hybrid automatic repeat request (HARQ) retransmission is configured based on the SL resource pool information, and selecting at least one resource for transmission of a physical sidelink shared channel (PSSCH) based on the determining that the HARQ retransmission is configured. The at least one resource is determined for ensuring a time gap, based on at least one of a period of resources configured for a physical sidelink feedback channel (PSFCH), an offset between a slot of a PSSCH transmission and a slot of a PSFCH reception, or a time required for reception and processing of the PSFCH plus a time required for SL retransmission preparation.

Abstract: An apparatus and a method for allocating resources in a wireless communication system is provided. More specifically, a method of determining an uplink transmission resource region for performing a channel access procedure of the BS through a channel access procedure type and subcarrier spacing and determining configuration of downlink resources of the BS through scheduling information and slot structure information is proposed. A method of operating a terminal in a wireless communication system includes acquiring a maximum channel occupancy time (MCOT) of the terminal within an unlicensed band, determining a time interval which a base station (BS) can use for downlink signal transmission in the maximum channel occupancy time, transmitting the maximum channel occupancy time and time information related to the time interval to the BS and receiving a downlink signal from the BS during the time interval in the maximum channel occupancy time.
