Abstract
Methods, systems, and devices for wireless communications are described. A wireless device that uses a first radio access technology (RAT) may identify a transmission timing scheme for a shared radio frequency spectrum band, the transmission timing scheme comprising a first set of time intervals allocated for transmissions using a first RAT and a second set of time intervals allocated for transmissions using a second RAT. The wireless device may transmit, during a time interval of the first set of time intervals, a channel reservation signal indicating an end time of the time interval and indicating that the wireless device uses the first RAT. The wireless device may transmit, based at least in part on the transmitted channel reservation signal, over the shared radio frequency spectrum band during at least a portion of the time interval before the end time of the time interval.
