Abstract

MéTODO DE NOTIFICAçãO DE QUALIDADE DE RECEPçãO, APARELHO DE TERMINAL DE COMUNICAçãO SEM FIO, E APARELHO DE ESTAçãO DE BASE. A presente invenção refere-se a um método de notificação de qualidade de recepção, que é mostrado, o qual melhora a produção de linha de fluxo contrário pela redução da quantidade de dados de dados de qualidade de recepção de sinais de portadora múltipla de fluxo normal a serem transmitidos para um aparelho de estação de base na linha de fluxo contrário. Também são mostrados um aparelho de estação de base e um aparelho de terminal de comunicação sem fio de um consumo de potência baixo para uso naquele método de notificação de qualidade de recepção. No aparelho, quando um aparelho de terminal de comunicação sem fio (100) recebe um sinal de portadora múltipla de fluxo normal e, então, notifica um aparelho de estação de base (200) de uma subportadora tendo uma qualidade de recepção desejável para o sinal de portadora múltipla de fluxo normal, ele produz dados de qualidade de recepção de uma pluralidade de formatos, então seleciona, a partir de dentre os dados de qualidade de recepção produzidos, um tendo a quantidade de dados mais baixa e, então, transmite os dados de qualidade de recepção selecionados para o aparelho de estação de base (200), pelo uso de uma subportadora de sinal de portadora múltipla de fluxo contrário designada pelo aparelho de estação de base (200).
