<p>The invention relates to a data transmission method for a communication facility comprising a transceiver master station exchanging signals containing data with transceiver terminals through a channel operating in two directions and shared over time by the terminals and the station. In order to avoid contention on the up channel assigned to transmission from the terminals to the station during time windows (40M) of the up channel, there is provided a phase for exchanging contention information between the station and the terminals, in the form of pulsed signals (60, 61, 62) presented within time slots (51, 52) preserving the anonymity of the terminals. This phase is executed ahead of each time window (40M) and enables the station to authorise a single terminal to transmit during this time window. <IMAGE></p> |
