1. A device, comprising:
a processor; and
a memory operatively connected to the processor, and including computer code that when executed, causes the processor to:
transmit a short data frame in accordance with a first rate over a channel during a spatial reuse transmit opportunity;
upon successful transmission of the short data frame, transmit one or more subsequent data packets at the first rate or a second rate higher than the first rate during the spatial reuse transmit opportunity or a subsequent spatial reuse transmit opportunity; and
upon unsuccessful transmission of the short data frame, transmit the one or more subsequent data packets at a third rate less than the first rate during the spatial reuse transmission opportunity or a subsequent spatial reuse transmit opportunity, wherein unsuccessful transmission of the short data frame comprises a determination that the short data frame was unacknowledged by a receiving device;
transmit a subsequent short data frame at the third rate;
upon successful transmission of the subsequent short data frame, transmit the one or more subsequent data packets at the third rate during the spatial reuse transmit opportunity or the subsequent spatial reuse transmit opportunity.
