Abstract

<B>"CONTROLE INDIRETO PERMANENTE, PARTICIPANTE MóVEL, PARA UM SISTEMA DE ACESSO MúLTIPLO POR DIVISãO DE CóDIGO (CDMA)"<D>. A presente invenção trata de um método e um sistema para controle indireto participante móvel entre estações de base que usam diferentes freq³ências portadoras, em um sistema celular de Acesso Múltiplo por Divisão de Código (CDMA). No método e aparelho da invenção, uma estação móvel executa medições de controle indireto nas transmissões de ligação avançada de estações de base de CDMA, candidatas à controle indireto, em que as transmissões de ligação avançada são transmitidas sobre uma freq³ência portadora da estação de base presente. As medições de controlo indireto são executadas durante quadros de transmissão selecionada, que definem períodos de transmissão na ligação reversa pela estação móvel. Durante o tempo de medição no quadro de transmissão selecionada, a estação móvel não recebe (perfura) dados enviados para ela na ligação avançada e não transmite dados na ligação reversa.
