Abstract

Los métodos para el relevo de un dispositivo inalámbrico desde una célula origen servida por una estación base de origen a una célula destino servida por una estación base de destino. Un método de ejemplo, implementado en la estación base de origen, comprende obtener un comando para la transmisión al dispositivo inalámbrico, que comprende información de configuración que comprende una indicación de al menos un tiempo de concesión de enlace ascendente para recursos de enlace ascendente en la célula objetivo, especificada en términos de al menos un valor de número (SFN) de cuadro del sistema. El método comprende además transmitir el comando al dispositivo inalámbrico. La información de configuración en el comando comprende información suficiente para permitir que el dispositivo inalámbrico determine el tiempo o los tiempos para acceder a los recursos del enlace ascendente en la célula objetivo sin obtener valores SFN de la célula objetivo. El comando puede ser un comando de relevo para una relevo de acceso aleatorio sin canal (sin RACH) del dispositivo inalámbrico a la célula objetivo.
