Title (EN) FILTERING CARRIER FREQUENCY OFFSET IN MULTI-USER MULTIPLE-INPUT AND MULTIPLE-OUTPUT ENVIRONMENT
(FR) FILTRAGE DE DÉCALAGE DE FRÉQUENCE PORTEUSE DANS UN ENVIRONNEMENT À ENTRÉES MULTIPLES ET SORTIES MULTIPLES MULTI-UTILISATEUR
Abstract: front page image
(EN)Methods, systems, and devices for wireless communication are described including determining one or more unfiltered CFOs, filtering the one or more unfiltered CFOs to identify a refined CFO based at least in part on the one or more unfiltered CFOs and a predetermined number of packets, modifying a transmission parameter based at least in part on the refined CFO, and transmitting a signal in a MU-MIMO environment based at least in part on the modified transmission parameter.
(FR)L'invention concerne des procédés, des systèmes, et des dispositifs de communication sans fil, consistant à : déterminer un ou plusieurs CFO non filtrés ; filtrer le ou les CFO non filtrés afin d'identifier un CFO affiné sur la base, au moins en partie, du ou des CFO non filtrés et d'un nombre prédéterminé de paquets ; modifier un paramètre de transmission sur la base, au moins en partie, du CFO affiné ; et transmettre un signal dans un environnement MU-MIMO sur la base, au moins en partie, du paramètre de transmission modifié.
