The invention relates to a method of implementing operations involving the processing a radio-communication frame (CMF) in a system comprising at least three radio transmitter/receiver devices (-), consisting in transmitting the frame in response to a first request signal (REQ) transmitted by a device belonging to the system (). According to the invention, the frame is processed in the device () that transmitted the first request signal (REQ) as well as in other devices belonging to the system (-) which transmitted respective request signals (REQ-REQ) within a pre-determined time period.

Processing of a radio-communication frame in a system comprising at least three radio transmitter/receiver devices

Data is transmitted by a first terminal () to a second terminal () in a telecommunications network () in a plurality of sets of data packets. In the first and second terminals, as a function of a selection rule common to the first and second terminals, transmission frequencies are selected from transmission frequencies in a secret list of transmission frequencies that is common to the first and second terminals. Next, the sets of data packets are transmitted () from the first terminal to the second terminal at respective selected transmission frequencies. The common list of transmission frequencies is allocated on the basis of available frequencies with respect to the first and second terminals and collected from the telecommunications network.
