Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may iterate a value of a channel access counter (CAC) to a trigger value based at least in part on configuring the value of the CAC. In some aspects, the first wireless communication device may utilize a channel access mechanism to select a set of time-frequency resources for a transmission of a packet based at least in part on iterating the value of the CAC to the trigger value. In some aspects, the first wireless communication device may transmit the packet to a second wireless communication device via the set of time-frequency resources based at least in part on utilizing the channel access mechanism to select the set of time-frequency resources for the transmission. Numerous other aspects are provided.

Divers aspects de la présente invention concernent de manière générale la communication sans fil. Selon certains aspects, un premier dispositif de communication sans fil peut itérer une valeur d'un compteur d'accès au canal (CAC) jusqu'à une valeur de déclenchement sur la base, au moins en partie, d'une configuration de la valeur du CAC. Selon certains aspects, le premier dispositif de communication sans fil peut utiliser un mécanisme d'accès au canal pour sélectionner un ensemble de ressources temps-fréquence pour une transmission d'un paquet sur la base, au moins en partie, de l'itération de la valeur du CAC jusqu'à la valeur de déclenchement. Selon certains aspects, le premier dispositif de communication sans fil peut transmettre le paquet à un second dispositif de communication sans fil par l'intermédiaire de l'ensemble de ressources temps-fréquence sur la base, au moins en partie, de l'utilisation du mécanisme d'accès au canal pour sélectionner l'ensemble de ressources temps-fréquence pour la transmission. L'invention se présente également sous de nombreux autres aspects.
