A wireless transmit/receive unit (WTRU) may monitor LBT subbands to determine when a COT is activated. A WTRU may vary monitoring based on whether the WTRU received a full or partial COT structure. A WTRU may interpret a scheduling grant based on the set of acquired LBT subbands. A WTRU may determine a channel access priority (CAP) associated with a COT. A WTRU may indicate a CAP used to acquire a COT. A WTRU may receive an indication of a CAP used by a network to start a COT. A WTRU may determine a logical channel restriction based on a CAP associated with the COT. A WTRU may determine whether a logical channel may be included in a transmission during a COT based on a logical channel restriction. A transmission may be during a COT via a subband(s).
