Abstract

La presente descripción proporciona un método y sistema optimizado para activar y desactivar un portador de componente en un sistema de portador múltiple, el método comprende: cuando se activa un Portador de componente (CC), una estación base envía un comando de activación a un Equipo del usuario (UE) a través de la información de control de enlace descendente (DCI) para indicar el UE que active el CC; si recibe el comando de activación en forma exitosa, el UE activa el CC y envía un acuse de recibido del comando de activación a la estación base; cuando desactiva el CC, la estación base envía un comando de desactivación al UE a través del DCL para indicar al UE que desactive el CC; si se recibe con éxito el comando de desactivación, el UE desactiva el CC y envía un acuse de recibido del comando de desactivación a la estación base; la presente descripción puede mejorar la confiabilidad de activación y desactivación de la tecnología de adición de portador en un sistema LTE-A y tiene ventajas, tales como una configuración y operación simples, y mantiene consistentes el estado del CC en la estación base y el estado del CC en el UE.
