Abstract

Se describen tecnicas para realizar deteccion de duplicados y reordenacion para una transmision de HARQ. Para la deteccion de duplicados, un receptor determina si un paquete x descodificado para un canal y de ARQ es un paquete duplicado basado en el paquete x y un paquete descodificado previo para el canal y de ARQ. Para reordenacion, el receptor determina si un paquete previo aun esta pendiente en cualquier otro canal de ARQ basandose en paquetes descodificados previos para los canales de ARQ y envia el paquete x solamente si no existen paquetes previos pendientes. Si no existen paquetes previos pendientes en el otro canal z de ARQ si (1) un paquete descodificado se recibio en el canal z de ARQ en un tiempo designado o posterior o (2) un paquete descodificado no se recibio en el canal z de ARQ dentro de una ventana de tiempos del tiempo actual.
