摘要

A method for transmitting data packets in a communication network using a plurality of radio frequency channels, at least two of the radio frequency channels being concatenated to form a concatenated channel. The method includes: acquiring and reserving at least one of the channels from the concatenated channel, thus reserving a first frequency band for transmitting data packets to a first target device; acquiring and reserving channels from the concatenated channel that were unreserved during the first step of acquisition and reservation, thus reserving a second frequency band for transmitting data packets to a second target device; generating a preamble specific to a selected data packet, which includes a simultaneous transmission indicator on the first and second frequency bands; and simultaneously transmitting the data packets on the first and second frequency bands, from the selected packet and the specific preamble, before the selected packet on the second frequency band.

1. A method comprising:
transmitting data packets in a communications network using a plurality of radiofrequency channels, at least two of said radiofrequency channels being concatenated to form a concatenated channel, wherein transmitting comprises: a first step of acquiring and reserving at least one of the radiofrequency channels of the concatenated channel, reserving a first frequency band for transmission of data packets to a first destination device; a second step of acquiring and reserving radiofrequency channels of the concatenated channel not reserved during the first step of acquiring and reserving, reserving a second frequency band for transmission of data packets to at least one second destination device; at least one step of selecting a data packet from among said data packets to be transmitted to at least one second destination device; a step of generating at least one preamble specific to said selected packet, said preamble or preambles comprising at least one indicator of simultaneous sending on said first and second frequency bands, and a step of simultaneous sending of said data packets on said first and second frequency bands, of said selected packet and of said specific preamble or preambles, before said selected packet, on only said second frequency band.
