Devices and methods of transmit opportunity (TXOP) with continued listen-before-talk (LBT) are generally described. A user equipment (UE) can be configured to perform a single LBT during an LBT scanning instance, to detect availability of an unlicensed wireless channel. Upon detecting availability of the channel, data is encoded for transmission during a TXOP with a TXOP duration. A pause in the transmission of the data is initiated upon expiration of a first time interval of the TXOP. A continuous LBT procedure is performed upon expiration of the pause, to determine a plurality of sensing metrics indicating occupancy of the unlicensed wireless channel. The transmission of the data is resumed during the TXOP for a second time interval, when at least one sensing metric of the plurality of sensing metrics is below a threshold.
