Abstract:
1. A communication method using time division multiplexing between a master terminal and several slave terminals, data transmission being performed in successive frames, each frame being divided into a plurality of time slots, one of the time slots of each frame being reserved for the master terminal to transmit a synchronization signal, and each terminal being either in transmission mode or in listening mode during each time slot, wherein a terminal priority level is assigned to each terminal or to categories of data that each terminal can transmit; and wherein each slave terminal performs, for each current frame, the steps of: each slave terminal of the priority user transmits in a corresponding time slot a priority synchronization signal different from the synchronization signal of the master terminal, the priority synchronization signal indicating a user of the slave terminal is the priority user and that the corresponding time slot is a reserved time slot unavailable to the other terminals.
