CA 2522032

In a wireless packet communication method for transmitting a plurality of wireless packets simultaneously by using multiple wireless channels determined to be idle by carrier sense, a wireless channel determined to be idle and MIMO, or the multiple wireless channel and the MIMO, a mandatory channel that is always used for transmission is set. The wireless packets are transmitted by using the wireless channel(s) including the mandatory channel only when the mandatory channel is idle. That is, in case of transmitting a plurality of wireless packets simultaneously, transmission is performed by using the wireless channel(s) including the mandatory channel, and transmission is not performed when the mandatory channel is not idle.

L'invention concerne un procédé de communication de paquets radio permettant de transmettre en parallèle une pluralité de paquets radio au moyen d'une pluralité de canaux radio déterminés comme ouverts par détection de porteuse, de transmettre en parallèle une pluralité de paquets radio au moyen d'un multiplexage spatial faisant appel à un canal radio unique déterminé comme ouvert, ou de transmettre en parallèle une pluralité de paquets radio au moyen d'une combinaison de ces techniques. Ce procédé consiste à établir un canal indispensable nécessairement utilisé pour la transmission, et, à condition que le canal indispensable soit ouvert, à utiliser des canaux radio comprenant ce canal indispensable pour transmettre les paquets radio. En d'autres termes, dans le cas d'une transmission en parallèle d'une pluralité de paquets radio, on utilise des canaux radio comprenant le canal indispensable pour la transmission, la transmission n'étant pas possible si le canal indispensable n'est pas ouvert.
