CA 2518741

A transmit-side STA transmits a wireless packet using a wireless channel which has been determined to be idle by both a physical carrier sense for determining based on received power whether the wireless channel is busy or idle and a virtual carrier sense for determining the wireless channel to be busy during set transmission inhibition time. At this time, the transmit-side STA sets transmission time used for the virtual carrier sense to a paired wireless channel which is affected by leakage from a transmitting wireless channel. This allows for setting transmission inhibition time to a paired wireless channel even when the paired wireless channel cannot successfully receive due to the effect caused by leakage from the transmitting wireless channel.

Une station de radio côté transmission transmet un paquet de radiocommunication au moyen d'un canal radio estimé libre par une détection de porteuse physique de détermination de l'état occupé ou de l'état libre selon la puissance de réception ainsi que par une détection de porteuse virtuelle de détermination de l'état occupé lors d'une période de suppression de transmission établie. Une période de suppression de transmission utilisée pour la détection de porteuse virtuelle est établie pour un canal radio formant une paire et affecté par la fuite en provenance du canal radio de transmission. Ainsi, même lorsque la réception normale ne peut être effectuée dans le canal radio affecté par la fuite en provenance du canal radio de transmission, une période de suppression de transmission peut être établie pour le canal radio affecté.
