CA 2515537

A plurality of data packets that contain sequence numbers, respectively, are transmitted simultaneously between two stations (STAs) by using a wireless channel and multiple inputs and multiple outputs (MIMO). An STA receiving the plurality of data packets, transmitted simultaneously by using MIMO, generates a single acknowledgement (ACK) packet containing information that corresponds to a sequence number of each data packet successfully received, and transmits the single ACK packet to a transmit-side STA without using MIMO. Thus, a radio of successful ACK packet receptions to total receptions can be increased. An effect of improving throughput achieved by simultaneous transmission can also be ensured.

Selon l'invention, une pluralité de paquets de données contenant un numéro de séquence sont transmis en parallèle entre deux stations radio au moyen d'un canal radio et d'un multiplexage spatial. La station radio ayant reçu une pluralité de paquets de données transmis en parallèle au moyen du multiplexage spatial crée une réponse affirmative unique contenant des informations équivalentes au numéro de séquence du paquet de données reçu avec succès et renvoie cette réponse à la station radio du côté transmission sans multiplexage spatial. Ceci permet d'augmenter la probabilité de transmission avec succès du paquet de données affirmatif, assurant ainsi l'amélioration du débit par la transmission en parallèle.
