Abstract
In some aspects, the disclosure is directed to methods and systems for transmitting packets (including but not limited to MU-MIMO packets). An access point communicating wirelessly with a plurality of devices can determine that a first packet for a first device of the plurality of devices has a first transmission duration. The access point can determine that a second packet for a second device of the plurality of devices has a second transmission duration shorter than the first transmission duration. The access point can adjust, based on the determination, a transmission power or a modulation and coding scheme to transmit the second packet during a third transmission duration. The third transmission duration can be greater than the second transmission duration.
