Abstract

Un método y un aparato permiten la decodificacion confiable y de baja complejidad de ráfagas de comunicacion del. EGPRS2 cuando los equipos del RTTI y del BTTI operan en el/los mismo/s segmento/s de tiempo. Son diversas las configuraciones para el mapeo de la bandera de estado del enlace ascendente (USF) que emplean la permuta del bit ajustable de algunos o todos los bits codificados por el canal de la USF, en las ráfagas de comunicacion. También se describen configuraciones que permiten un uso ajustable de la etapa del mapeo del símbolo en el transmisor y el receptor para permitir más rendimiento y/o complejidad reducida. Las reglas de mapeo admisible son conocidas por el receptor y el transmisor Y, en consecuencia, reducen la complejidad de la decodificacion de esta informacion. Para incrementar el rendimiento de ráfagas de comunicacion del EGPRS2, las transmisiones del RTTI de tipos de modulacion diferente o esquemas de codificacion y modulacion del EGPRS/EGPRS2 durante un intervalo del BTTI se introducen para permitir una decodificacion confiable de la USF y una complejidad de decodificador reducida.
