Contiguous configured and grant-based ul transmissions on nr-u systems

A method comprising:

• determining, at a user equipment (UE) for a wireless communication system, a first listen before transmission (LBT) priority class for a first order of uplink (UL) transmission and a second LBT priority class for a second order of UL transmission;
• determining, at the UE, a total length of a UL transmission comprising a first length of the first order of UL transmission and a second length of the second order of UL transmission;
• upon determination that the first LBT priority class is at least equal to the second LBT priority class, and a maximum channel occupancy time (MCOT) corresponding to the first order of UL transmission is at least the total length of the UL transmission, performing, by the UE, an LBT procedure to acquire a channel for the UL transmission;
• and
• in response to acquiring the channel, performing, by the UE, the UL transmission using the first order of UL transmission followed by the second order of UL transmission.

A non-transitory computer-readable media (CRM) comprising computer instructions, where upon execution of the computer instructions by one or more processors of a user equipment (UE), causes the one or more processors to:

• determine a first listen before transmission (LBT) priority class for a first order of uplink (UL) transmission and a second LBT priority class for a second order of UL transmission;
• determine a total length of a UL transmission comprising a first length of the first order UL transmission and a second length of second order UL transmission;
• upon determination that the first LBT priority class is at least equal to the second LBT priority class, and a maximum channel occupancy time (MCOT) corresponding to the first order of UL transmission is at least the total length of the UL transmission, perform an LBT procedure to acquire a channel for the UL transmission;
• and
• in response to acquiring the channel, perform the UL transmission using the first order of UL transmission followed by the second order of UL transmission.
