Title (EN) METHODS, SYSTEMS, AND APPARATUS FOR REDUCING CO-CHANNEL INTERFERENCE IN FULL-DUPLEX WI-FI
(FR) PROCÉDÉS, SYSTÈMES ET APPAREIL PERMETTANT DE RÉDUIRE LES INTERFÉRENCES DE CO-CANAUX DANS UN WI-FI EN DUPLEX INTÉGRAL
Abstract:
(EN) Methods and apparatus for reducing co-channel interference in full-duplex Wi-Fi are disclosed. An example apparatus includes a receiver to receive a pilot tone pattern corresponding to a reservation of a first pilot sub-carrier for at least one of uplink or downlink transmission; and an uplink/downlink converter to when the first pilot sub-carrier is reserved for uplink transmission during a full-duplex transmission, refrain from receiving a downlink packet; and when the first pilot sub-carrier is not reserved for uplink transmission, receiving a downlink packet.
(FR) L'invention concerne des procédés et un appareil permettant de réduire les interférences de co-canaux dans un Wi-Fi en duplex intégral. Un appareil donné à titre d'exemple comprend un récepteur destiné à recevoir un motif de tonalité pilote correspondant à la restriction d'une première sous-porteuse pilote au moins à la transmission en liaison montante ou en liaison descendante; et un convertisseur liaison montante/liaison descendante destiné, lorsque la première sous-porteuse pilote est réservée à une transmission en liaison montante pendant une transmission en duplex intégral, à s'abstenir de recevoir un paquet de liaison descendante; et, lorsque la première sous-porteuse pilote n'est pas réservée à une transmission en liaison montante, à recevoir un paquet de liaison descendante.
