Abstract
Systems and methods are provided for using a short data frame sent at a particular rate that can be used to probe a channel on which an access point is operating. The rate can be increased/decreased depending on whether or not transmission of the short data frame was successful or not. In this way, the highest possible rate (which can be impacted by any or all of the following factors: number of spatial streams, modulation and coding scheme, channel bandwidth, guard interval) can be selected to transmit data on the channel. In other words, a transmission rate can be selected dynamically and on a per-packet basis for a spatial reuse data frame that would follow the short data frame based on whether transmission of the short data frame was successful.
