Configuring a Preamble for Trigger-Based Protocol Data Unit

Abstract:

Techniques for trigger-based transmission in a wireless network include receiving, at a first wireless device, a trigger signal including an indication of a first value for a parameter of a trigger-based physical layer protocol data unit (TB PPDU) transmission to a second wireless device, selecting, by the first wireless device, a second value for the parameter of the TB PPDU transmission, wherein the second value for the parameter is different from the first value for the parameter, and transmitting, by the first wireless device and to the second wireless device, the TB PPDU transmission using the second value for the parameter.
