Abstract

Some demonstrative embodiments of the invention include a method, apparatus for concurrently transmitting data to two or more wireless stations.

Claims

1. A method of simultaneously transmitting data to two or more wireless stations, the method comprising:

obtaining a first aggregated data frame to be transmitted to a first station;

obtaining second and third aggregated data frames to be transmitted to a second station;

concurrently transmitting the first aggregated data frame to the first station and the second aggregated data frame and a portion of the third aggregated data frame to the second station, wherein the transmission duration of the first aggregated data frame is substantially equal to the transmission duration of the second aggregated data frame and the portion of the third aggregated data frame.
