Abstract

Equipo de usuario en un sistema de comunicación móvil en el que los paquetes de una portadora están divididos entre una pluralidad de estaciones base, y los paquetes divididos de la portadora se transmiten desde la pluralidad de estaciones base al equipo de usuario está provisto con: una unidad de recepción que recibe secuencialmente los paquetes de la portadora de la pluralidad de estaciones base; y una unidad de procesamiento de paquetes duplicados que, al detectar un paquete duplicado que se duplica con algún paquete de entre los paquetes recibidos por la unidad de recepción, determina si un protocolo de comunicación de paquetes predeterminado que incluye un protocolo de compresión/expansión de encabezado se restablece en el equipo de usuario, y cuando el protocolo de comunicación de paquetes predeterminado no se restablece, abandona el paquete duplicado sin llevar a cabo el procesamiento de expansión de encabezado en el paquete duplicado.
