(EN) MANAGING MEDIUM ACCESS FOR WIRELESS DEVICES
(FR) GESTION D'ACCÈS AU SUPPORT POUR DISPOSITIFS SANS FIL
Abstract
(EN)
Apparatuses and methods are disclosed for managing access to a wireless medium. In one example, a first wireless device contends for access to the wireless medium using a random channel access mechanism, and then obtain a medium resource unit (MRU) for a master transmit opportunity (TXOP) duration. The first wireless device, which controls medium access for the master TXOP duration, may transmit data on the wireless medium using the obtained MRU and/or may grant medium access via the obtained MRU to a number of second wireless devices.

L'invention concerne des appareils et procédés permettant de gérer l'accès à un support sans fil. Dans un exemple, un premier dispositif sans fil tente d'avoir accès au support sans fil à l'aide d'un mécanisme d'accès au canal aléatoire, puis d'obtenir une unité de ressources support (MRU) pendant une durée d'opportunité de transmission (TXOP) maîtresse. Le premier dispositif sans fil, qui commande l'accès au support pendant la durée de TXOP maîtresse, peut transmettre des données sur le support sans fil à l'aide de la MRU obtenue et/ou peut accorder l'accès au support par l'intermédiaire de la MRU obtenue à un certain nombre de seconds dispositifs sans fil.
