Abstract

Patente de Invenção: <B>"APARELHO DE COMUNICAçãO DE RáDIO E MéTODO DE CONTROLE DE COEFICIENTE DE TRANSMISSãO"<D>. O aparelho terminal de comunicação mede a qualidade de recepção e relata o resultado da medida ao aparelho de estação de base, e o aparelho de estação de base chaveia o coeficiente de transmissão baseado no resultado relatado da qualidade de recepção. Desta maneira o coeficiente de transmissão é chaveado começando no momento em que a qualidade de recepção do aparelho terminal de comunicação se deteriora. Além disso, o coeficiente de transmissão é chaveado de forma que a quantidade de interferência com outros esteja dentro da faixa permissível de acordo com a condição de canal entre o aparelho terminal de comunicação e o aparelho de estação de base.
