Abstract

Un procedimiento para traspaso de comunicación inalámbrica, comprendiendo el procedimiento: transmitir, por una célula de destino (106), un preámbulo dedicado de canal de acceso aleatorio, RACH, e información de célula a una célula de origen (104); recibir, en la célula de destino (106), una comunicación RACH desde un equipo de usuario, UE, (102) que comprende el preámbulo RACH dedicado para iniciar la comunicación con la célula de destino (106); y transmitir, por la célula de destino (106), una concesión de enlace ascendente (112) que acompaña a un mensaje de traspaso al equipo de usuario en respuesta a recibir el RACH, en donde transmitir la concesión de enlace ascendente (112) comprende asignar recursos de enlace ascendente de tamaño suficiente como para permitir la recepción por la célula de destino un mensaje de estado de Protocolo de Convergencia de Datos por Paquetes, PDCP, sobre una o más portadoras de datos de radio configuradas, DRB, y un informe de estado de memoria temporal, BSR, desde el UE
