Abstract

La presente invención revela un UE (Equipo de Usuario) y un método del UE para recibir datos del enlace descendente para evitar la ocurrencia de errores cuando el UE recibe los datos del enlace descendente. El método consta de los siguientes pasos: durante el restablecimiento, en el proceso de transmitir Unidades de Datos de Servicios (SDU) a una entidad del Protocolo de Convergencia de Datos de Paquete (PDCP) desde una entidad de Control de Enlace de Radio (RLC) en el UE, si la entidad de PDCP considera que el Número de Secuencia (SN) de PDCP) desde una entidad de Control de Enlace de Radio (RLC) en el UE, si la entidad de PDCP considera que el Número de Secuencia (SN) de PDCP de la Unidad de Datos de Protocolo (PDU) de PDCP recibida que incluye la SDU satisface la condición de reporte, la PDU de PDCP es recibida y la SDU incluida en la PDU de PDCP es sometida a la entidad de capa superior, en donde la condición de reporte es: PDCP SN = (Last_Submitted_PDCP_RX_SN+1) % (Maximum_PDCP_SN+1).
