Title (EN) STATION (STA), ACCESS POINT (AP) AND METHODS TO INDICATE A RESTRICTION OF CONTENTION BASED ACCESS
(FR) STATION (STA), POINT D'ACCÈS (AP) ET PROCÉDÉS POUR INDIQUER UNE RESTRICTION D'ACCÈS À BASE DE CONTENTION
Abstract:
(EN) Embodiments of a station (STA), an access point (AP) and methods of communication are generally described herein. The STA may receive control signaling that indicates a target wakeup time service period (TWT SP) for contention based access by the STA for transmission of uplink control frames. The TWT SP may be included in a beacon interval. The STA may contend for access during the TWT SP. The STA may transmit an uplink control frame during the TWT SP. The STA may refrain from contention for access outside of the TWT SP during the beacon interval. The STA may attempt to detect trigger frames (TFs) outside of the TWT SP during the beacon interval. If a TF is detected, the STA may determine whether the detected TF indicates a scheduled transmission of an uplink data frame by the STA.
(FR) Les modes de réalisation de la présente invention concernent de manière générale une station (STA), un point d'accès (AP) et des procédés de communication. La STA peut recevoir une signalisation de contrôle qui indique une période de temps de réveil cible (TWT SP) pour un accès basé sur la contention par la STA pour la transmission de trames de commande de liaison montante. Le TWT SP peut être inclus dans un intervalle de balise. La STA peut entrer en concurrence pour un accès pendant le TWT SP. La STA peut transmettre une trame de commande de liaison montante pendant le TWT SP. La STA peut s'abstenir de la contention pour accéder à l'extérieur du TWT SP pendant l'intervalle de balise. La STA peut tenter de détecter des trames de déclenchement (TF) à l'extérieur du TWT SP pendant l'intervalle de balise. Si une TF est détectée, la STA peut déterminer si la TF détectée indique une transmission programmée d'une trame de données de liaison montante par la STA
