Abstract

<B>MéTODO E APARELHO DE COMUNICAçãO DE LINK ASCENDENTE ENTRE UMA ESTAçãO MóVEL E UMA ESTAçãO BASE DE UM SISTEMA DE COMUNICAçãO SEM FIO<D> Técnicas aperfeiçoadas de sincronização de temporização e de controle de acesso para uso em um sistema sem fio multiplexado de divisão de freq³ência ortogonal (OFDM) ou outro tipo de sistema de comunicação sem fio. De acordo com a invenção, um sistema de controle de acesso e de sincronização de link ascendente é provido no qual as estações móveis transmitem certos sinais de temporização e de acesso em intervalos dedicados em uma seq³ência de link ascendente. Controle de acesso é implementado ilustrativamente como um processo de dois estágios no qual uma estação móvel determinada transmite primeiro um sinal genérico de acesso de link ascendente em um dos intervalos. Se esse acesso for aceito, a estação base transmite uma confirmação de acesso contendo correções iniciais de energia e de temporização, junto com atribuições iniciais de canal no qual a estação móvel pode iniciar um processo de estabelecimento de chamada. Para re-sincronização, estações móveis transmitem sinais de sincronização de temporização nos intervalos dedicados de temporização e de acesso. A estação base mede o tempo de chegada dos sinais, e envia de volta correções apropriadas de temporização. A invenção dessa forma garante que seja mantida a ortogonalidade entre as estações móveis.
