Abstract

<B>SISTEMA DE CONTROLE DA MICRODIVERSIDADE TENDO UM MODO DE MACRODIVERSIDADE BASEADO NA CATEGORIA DE OPERAçãO DA UNIDADE SEM FIO<D> Um sistema de controle de macrodiversidade provê uma unidade sem fio com um modo de macrodiversidade dependendo da categoria da operação da unidade sem fio. Por exemplo, um sistema de comunicação sem fio pode ter unidades sem fio operando em categorias relacionadas à mobilidade da unidade sem fio, tal como fixa, fixa limitada (mobilidade dentro da célula doméstica) e/ou completamente móvel. Para uma unidade sem fio, o modo de macrodiversidade da unidade sem fio pode ser estabelecido dependendo da categoria de operação para a unidade sem fio. Onde a unidade sem fio é fixa e tem boa recepção de uma estação de base doméstica, especificamente em regiões próximas à estação de base doméstica, a macrodiversidade para a unidade sem fio pode ser restrita. Devido ao fato de a mobilidade da unidade sem fio ser restrita no modo fixo (ou fixo limitado), o desvanecimento dos sinais entre a estação de base doméstica e a unidade sem fio não deve ser severo; dessa forma a macrodiversidade é desabilitada. Onde a recepção é fraca, especificamente em uma região próxima à borda da célula, a macrodiversidade para a unidade fixa (ou fixa limitada) é habilitada. A unidade sem fio fixa (ou fixa limitada) na borda da célula pode se beneficiar da macrodiversidade mas, devido ao fato de a unidade sem fio ser fixa (ou fixa limitada), a unidade sem fio fixa (ou fixa limitada) não é transferida para outra estação de base (ou pode somente ser transferida para um grupo limitado de estações de base).
