Abstract

"SISTEMA DE COMUNICAçãO POR RáDIO". A presente invenção refere-se a um aparelho estação móvel 101-1 detecta e relata um valor de qualidade de recepção de um sinal conhecido transmitido a partir de um aparelho estação base 102-1. O aparelho estação base 102-1 possui uma seção de geração de sinal de deficiência de qualidade 1021 que compara o valor de qualidade de recepção com um valor limite predeterminado e gera um sinal de deficiência de qualidade quando é apresentado que o valor de qualidade de recepção é menor do que o valor limite predeterminado e uma seção de relato de sinal de deficiência de qualidade 1024 que relata um identificador do aparelho estação móvel 101-1 correspondendo ao sinal de deficiência de qualidade para um aparelho de controle de estação base 103. O aparelho de controle de estação base 103 possui uma seção de transmissão de sinal de controle 1031 que transmite um sinal de controle para trocar a transmissão de dados por meio do HSDPA para o aparelho estação móvel 101-1 para a transmissão de dados por meio do DPCH.
