Category-2 listen-before-talk (LBT) options for new radio-unlicensed (NR-U)

An apparatus comprising:

• a transceiver configured to receive a first communication signal;
• and
• a processor configured to:
• perform a listen-before-talk (LBT) based at least in part on one or more channel measurements in one or more measurement periods of a gap duration between the first communication signal and a second communication signal, wherein a timing of the one or more measurement periods is based on a time-partitioning of the gap duration into a plurality of gap duration portions, and wherein a quantity of the plurality of gap duration portions is based on a length of the gap duration,
• wherein the transceiver is further configured to transmit the second communication signal based on the LBT.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a first wireless communication device to receive, from a second wireless communication device, a first communication signal;
• code for causing the first wireless communication device to perform a listen-before-talk (LBT) based at least in part on one or more channel measurements in one or more measurement periods of a gap duration between the first communication signal and a second communication signal, wherein a timing of the one or more measurement periods is based on a time-partitioning of the gap duration into a plurality of gap duration portions, and wherein a quantity of the plurality of gap duration portions is based on a length of the gap duration;
• and
• code for causing the first wireless communication device to transmit the second communication signal based on the LBT.
