Abstract

"PROCESSOS PARA PROCESSAR COMUNICAçõES DUPLICADAS TRANSMITIDAS E PARA EXECUTAR TRANSFERêNCIA SUAVE DENTRO DE UM SISTEMA DE COMUNICAçõES, E, DISPOSITIVO DE COMUNICAçõES". Durante uma transferência "faça antes de interromper" executada dentro de um sistema de comunicações CDMA, comunicações duplicadas enlace inferior (50) são geradas e encaminhadas através de diferentes estações base (16) para despacho para a estação móvel (18). Na estação móvel, os sinais duplicados são recebidos e os números de sequência de frame dos frames recebidos substancialmente simultaneamente (58) nela são comparados (60). Se os números de sequência não casarem, os sinais duplicados são identificados como não sendo recebidos sincronamente pela estação móvel. Em resposta a isto, a estação móvel sinaliza (64) a rede de comunicações no enlace superior com uma mensagem de ajuste de distribuição, e modificações apropriadas de distribuição (66) são feitas em relação à transmissão de sinais duplicados. de modo a prover recepção substancialmente síncrona. Combinação de diversidade e decodificação (68) são então executadas sobre os sinais recebidos, alternativamente, a estação móvel amortece (72) o sinal chegando mais cedo e aguarda a chegada final do número de sequência casando com frame do sinal duplicado antes de engajar em combinação de diversidade e decodificação dos sinais recebidos.
