Abstract

Se proporciona un método para la detección de fallas LBT realizado por un UE. El método incluye: recibir, por parte de una entidad MAC del UE, una indicación de falla de LBT desde una capa inferior para todas las transmisiones UL; aumentar un contador de fallas de LBT cuando la entidad MAC recibe la indicación de falla de LBT; determinar que se produce un evento de falla de LBT cuando el contador de fallas de LBT es mayor o igual que un umbral; y restablecer el contador de fallas de LBT después de que la entidad MAC no haya recibido la indicación de falla de LBT durante un periodo de tiempo.
