Disclosed are methods for determining channel access for uplink transmissions. An example method (200) may include determining (210) a duration of a gap between an uplink transmission of a first apparatus and a downlink transmission of a second apparatus before the uplink transmission and in a channel occupancy time of the second apparatus in a case where the uplink transmission falls within the channel occupancy time, and determining (220) at least one of a channel access type and a cyclic prefix extension for the uplink transmission according to the duration of the gap. Related apparatuses and computer readable media are also disclosed.
