Abstract:
Techniques and described for wireless communication. One method includes generating a channel usage beacon signal (CUBS) at a wireless device, wherein a waveform of the CUBS is based at least in part on a scheduled uplink transmission by the wireless device; and transmitting, by the wireless device, the CUBS over an unlicensed radio frequency spectrum band to occupy the unlicensed radio frequency spectrum band prior to the scheduled uplink transmission.
