Abstract

Se describen métodos, sistemas y dispositivos para comunicaciones inalámbricas. En un método, una evaluación de canal libre (CCA) se puede realizar en una estación base para determinar la disponibilidad de un espectro sin licencia. Una primera forma de onda puede ser transmitida a un conjunto de equipos de usuario (UEs) sobre el espectro sin licencia cuando esté disponible. La primera forma de onda puede indicar un primer periodo de tiempo y un segundo periodo de tiempo durante los cuales la estación base tiene acceso de canal sobre el espectro sin licencia. Una segunda forma de onda puede ser recibida desde uno o más UEs que responden a la primera forma de onda. Cada segunda forma de onda puede ser recibida sobre el espectro sin licencia durante el primer periodo de tiempo y puede indicar que el respectivo UE tiene acceso de canal sobre el espectro sin licencia para recibir datos desde la estación base durante el segundo período de tiempo.
