Abstract

RESUMEN Se describen métodos, sistemas y dispositivos para usar un canal físico de control de enlace descendente (PDCCH) común para indicar los haces de transmisión que debe usar una estación base durante una oportunidad de transmisión o una periodicidad para monitorear espacios de búsqueda. Un equipo de usuario (UE) puede monitorear un espacio de búsqueda (en algunos casos, usando una periodicidad) para el PDCCH común para determinar si los haces de transmisión asociados con el UE deben usarse durante la oportunidad de transmisión. Si es así, el UE puede despertarse durante al menos una parte de la oportunidad de transmisión para recibir información adicional. Si el PDCCH común indica que no se van a utilizar haces de transmisión asociados con el UE durante la oportunidad de transmisión, el UE puede entrar o volver a entrar en el estado de reposo. El UE puede cambiar a una nueva periodicidad para monitorear el espacio de búsqueda basándose en la información transmitida dentro del PDCCH común.
