Abstract

Des aspects de la présente divulgation concernent des systèmes et des procédés de perforation d'au moins un symbole d'une transmission de liaison montante ou d'un ensemble de ressources de commande (CORESET) lors de la commutation de l'envoi d'une transmission de liaison montante (par exemple, Tx) dans un premier intervalle pour surveiller le CORESET pour une transmission de liaison descendante (par exemple, Rx) dans un second intervalle tout en fonctionnant dans un mode semi-duplex (HD) de division duplex en fréquence (FDD) pendant une procédure de canal d'accès aléatoire (RACH), lorsqu'au moins une condition basée sur une valeur d'avance temporelle (TA) est satisfaite. Par exemple, en mode HD-FDD, le temps nécessaire pour une commutation de Tx à Rx peut ne pas être suffisant pendant une procédure RACH, de telle sorte qu'au moins un symbole de la Tx ou de la Rx peut être perforé. La présente divulgation concerne des techniques de perforation d'un symbole sur la base de la valeur Ta, ainsi que le temps de commutation requis sur la base de la valeur de TA.
