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.

Abstract: A method for transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information by a user equipment (UE) in a wireless communication system is provided. The method includes receiving a physical downlink control channel (PDCCH) including information for downlink semi-persistent scheduling (DL SPS) release from a base station and transmitting an uplink channel including HARQ-ACK information for the PDCCH including the information for DL SPS release to the base station, in which a first symbol of the uplink channel is transmitted at least after a processing time (Tproc,3) from when a last symbol of the PDCCH is transmitted, and the processing time is determined based on a smaller value between a subcarrier spacing value of the PDCCH and a subcarrier spacing value of the uplink channel.
