Abstract:
A method for transmit time offset in a UL-MU-MIMO system monitors respective transmit powers, over a wireless channel, for a plurality of stations in the system. A respective transmit time offset is determined for each station in response to the respective transmit power of each station. A poll exchange sequence is initiated in which the transmit time offsets are transmitted to each respective station. An access point can then receive data from the stations at times adjusted by the respective transmit time offsets.
