Abstract

Patente de Invenção: <B>"PROCESSO, ESTAçãO MóVEL E ESTAçãO RADIOBASE PARA A SINCRONIZAçãO TEMPORAL PARA UMA ESTAçãO MóVEL EM UM SISTEMA DE RADIOCOMUNICAçãO"<D>. Um sistema de radiocomunicação oferece canais de freq³ência formados por fendas temporais e por meio de faixas de freq³ência de banda larga, nos quais são transmitidas simultaneamente informações de várias ligações entre estações móveis e estações de radiobase, onde as informações de ligações distintas são distinguíveis de acordo com uma estrutura fina individual por ligação. De acordo com a invenção são oferecidos, para as estações móveis no sentido descendente e de forma repetitiva, canais de freq³ência para a compensação temporal, onde uma forma de sinais é transmitida adicionalmente às informações de outras ligações. A estação móvel a ser sincronizada emite, a partir de sinais recebidos, pelos menos um instante temporal de chegada da forma de sinal, o qual é utilizado em seguida pela estação móvel para a sincronização temporal. A invenção encontra uma aplicação vantajosa por exemplo no modo-TDD da 3¬ geração de radiomóvel, que combina um procedimento de separação de usuários-CDMA e TDMA.
