Abstract

APARELHO E MéTODO PARA TRANSMITIR UMA INFORMAçãO DE QUALIDADE DE CANAL EM UM SISTEMA DE COMUNICAçãO. A presente invenção refere-se a um aparelho e a um método para transmitir/receber uma informação de canal de qualidade (CQI) em um sistema de comunicação que possui uma estrutura que inclui subcanais correspondentes ao mesmo fator de reutilização de freqúência ou a diferentes fatores de reutilização de freqúência. Uma estação base (BS) aloca pelo menos um dos subcanais na estrutura em uma estação de assinante (SS>, e envia a solicitação de transmissão para uma CQI para um subcanal desejado a ser recebido, na SS. A SS mede a qualidade do canal para subcanais individuais solicitados pelo BS em resposta à solicitação da CQI e transmite a qualidade de canal medido para a BS.
