Over-the-air signaling for an increased reuse factor in a shared radio frequency spectrum band

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• receive, at a first user equipment (UE), a first communication over a shared radio frequency spectrum band from a first base station, the first communication comprising a pre-grant communication associated with a downlink transmission or a grant of uplink resources associated with an uplink transmission;
• determine, based at least in part on receiving the first communication, whether a channel reservation signal is detected over the shared radio frequency spectrum band;
• and
• transmit a second communication over the shared radio frequency spectrum band, to the first base station, based at least in part on the determining, the second communication comprising an approval of the downlink transmission or the uplink transmission.

A method of wireless communication, comprising:

• detecting, at a first base station, a channel reservation for transmission over a shared radio frequency spectrum band;
• determining, based at least in part on the channel reservation for transmission, whether a channel reservation for reception signal is detected over the shared radio frequency spectrum band;
• and
• transmitting a communication over the shared radio frequency spectrum band, to a first user equipment (UE), based at least in part on the determining, the communication comprising a pre-grant communication associated with a downlink transmission or a grant of uplink resources associated with an uplink transmission.
