Abstract

Codificado de símbolos de modulacion, específico para usuario, para diversos segmentos de enlace ascendente, por ejemplo, el canal de acuse de recibo de tráfico de canal ascendente (ULTACH, uplink traffic acknowledgement channel), el canal de requerimiento de estado de enlace ascendente (ULSRCH, uplink state request channel, y el canal de control dedicado de enlace ascendente (ULDCCH, uplink dedicated control channel). A un terminal inalámbrico se le asigna un identificador de codificado de un terminal inalámbrico. Se determina un conjunto de símbolos de modulacion ordenados ingresados para un segmento dedicado de enlace ascendente al cual ha de aplicarse codificado específico para el usuario. Uno de los bits del identificador de codificado de un terminal inalámbrico asignado se asocia con cada uno de los símbolos de modulacion ordenados ingresados de un segmento de acuerdo con un mapeo determinado. Para cada símbolo de modulacion ingresado se lleva a cabo una operacion de codificado, por ejemplo, una rotacion de fase del símbolo de modulacion ingresado, como una funcion del bit identificador de codificado específico para el usuario, asociado, para obtener un correspondiente símbolo de modulacion emitido. Se asocia un valor de (0, 1) para un bit de ID de codificado con una cantidad (primera, segunda) de rotacion de fase, por ejemplo, (0, 180) grados, respectivamente.
