Abstract
The disclosure relates to the transmission of data by packets, in a network, with a search for an optimum use of the allocated band of frequencies. The packets are all formed by a header followed by an information field. The headers are all sent out on the same carrier frequency and the radio resources allocated to an information field are limited to a parallelogram demarcated by two first parallels corresponding to two fixed frequencies external to the frequencies allocated to headers and by two second parallels that have the same frequency/time slope for all the packets and whose position in time is deduced from the observation of the header. Thus, with knowledge of the resources used by the packets that are being transmitted, a terminal may send out a new packet as closely as possible to the packets that are being transmitted, but without any risk of interference with these packets. Application to transmission by packets.
