Abstract

Se describen sistemas y métodos relacionados con una diferencia de sincronización de transmisión entre células en un sistema de varias portadoras en el que al menos una de las células es sujeta a evaluación de canal libre (CCA) antes de transmitir. En algunas modalidades, un método de operación de un equipo de usuario (UE) comprende determinar una diferencia de sincronización de transmisión entre una primera célula que opere en una primera portadora y una segunda célula que opere en una segunda portadora, en donde es necesario llevar a cabo CCA en al menos uno de un primer canal en el que se encuentra la primera portadora y un segundo canal en el que se ubica la segunda portadora antes de que al UE se le permita transmitir. El método comprende además usar la diferencia de sincronización de transmisión para una o más tareas operativas del UE. La diferencia de sincronización de transmisión se determina cuando el primer canal y el segundo canal están disponibles en el UE.
