Abstract

"dispositivo de radiotransmissão e méto- do de radiotransmissão". a presente invenção refere-se a um dispositivo e método de radiotransmissão que ermite a redução de um aumento de memórias cgi para o canal de controle e um melhoramento da taxa de transmissão efetiva do canal de dados. quando transmissões multiplexadas através do canal de controle e do canal de dados são realizadas e quando a modulação adaptável é aplicada para ambos os canais, uma seção de seleção de mcs (108) é proporcionada com uma tabela de cqis para o canal de dados e tabelas de cqis para o canal de controle, e uma seção de determinação de mcs de seleção de tabela (201) seleciona uma das tabelas dependendo da largura de banda de transmissão do terminal e determina o mcs do canal de controle enquanto consultando a tabela de cqis selecionada.
