Abstract
The present invention concerns a transmission system where DiL and MU UL scheme are triggered by the AP simultaneously. According to a first aspect of the invention, the data frame sent in DiL mode by a station in response to an AP triggering frame are emitted according to the synchronization scheme adopted in MU scheme. This means that pre-correction parameters are computed based on the triggering frame from the AP for the transmission of the data frame. According to a second aspect of the invention, the return frame from the destination station of a DiL transmission to the source station, typically an acknowledge frame, when present, is transmitted using pre-correction parameters computed by the destination of the DiL transmission. These pre-correction parameters may be computed based on the received data frame from the source station of the DiL transmission or, when available, based on a previous frame received from the AP.
