Title
(EN) SIMPLIFIED SCHEDULING INFORMATION FOR ACKNOWLEDGEMENT IN A WIRELESS COMMUNICATION SYSTEM
(FR) INFORMATIONS DE PROGRAMMATION SIMPLIFIÉES D’ACCUSÉ DE RÉCEPTION DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN) A method is implemented by a station (STA) in a wireless network to provide an uplink (UL) Orthogonal Frequency Division Multiple Access (OFDMA) acknowledgement. The method includes receiving a first Physical Layer Protocol Data Unit (PPDU), where a Media Access Control (MAC) header of a MAC Protocol Data Unit (MPDU) in the first PPDU includes a Simplified Scheduling Information subfield that carries scheduling information for scheduling the UL OFDMA acknowledgement. The method further includes generating a second PPDU that includes an acknowledgement frame, determining an uplink cyclic prefix length to apply to the second PPDU based on a cyclic prefix length of the first PPDU, where the uplink cyclic prefix length is longer than the cyclic prefix length of the first PPDU, and transmitting the second PPDU through a wireless medium according to the scheduling information, where the uplink cyclic prefix length is applied to the second PPDU.
(FR) L’invention concerne un procédé mis en œuvre par une station (STA) dans un réseau sans fil pour émettre un accusé de réception d’accès multiples à division de fréquence orthogonale (OFDMA) en liaison montante (UL). Le procédé consiste à recevoir une première unité de données de protocole en couche physique (PPDU), un entête de contrôle d’accès multimédia (MAC) d’une unité de données de protocole MAC (MPDU) dans la première PPDU incluant un sous-champ d’informations de programmation simplifiées qui porte des informations de programmation pour la programmation de l’accusé de réception d’OFDMA en UL. Le procédé consiste en outre à générer une deuxième PPDU qui inclut une trame d’accusé de réception, à déterminer une longueur de préfixe cyclique en liaison montante à appliquer à la deuxième PPDU sur la base d’une longueur de préfixe cyclique de la première PPDU, la longueur de préfixe cyclique en liaison montante étant supérieure à la longueur de préfixe cyclique de la première PPDU, et à émettre la deuxième PPDU au moyen d’un support sans fil en fonction des informations de programmation, la longueur de préfixe cyclique en liaison montante étant appliquée à la deuxième PPDU.
