Abstract

Des modes de réalisation de la présente divulgation concernent des dispositifs, des procédés et un support non transitoire lisible par ordinateur pour une gestion de collision. Un dispositif terminal reçoit une signalisation indiquant un sous-ensemble de symboles flexibles comme symboles de liaison descendante (DL) ou des symboles flexibles provenant d'un dispositif réseau, le sous-ensemble de symboles flexibles provenant d'un ensemble de symboles flexibles conçus avec une sous-bande de liaison montante (UL). Le dispositif terminal détermine s'il faut effectuer une transmission UL dans l'ensemble de symboles flexibles s'il est ou non déterminé que la transmission UL se trouve à l'intérieur de la sous-bande UL. Le dispositif terminal effectue la transmission UL dans l'ensemble de symboles flexibles lorsque la transmission UL se trouve à l'intérieur de la sous-bande UL. De cette manière, l'annulation de la transmission UL peut être évitée lorsqu'une collision DL et UL se produit, et ainsi les performances des communications sont améliorées.
