Abstract

retorno de informações do estado do canal. um aparelho e método para divulgar a realimentação de informações de estado de canal. o método de fornecimento da informação de estado de canal para um canal de comunicações sem fio fornecido entre um primeiro nó de rede tendo pelo menos uma antena de transmissão e um segundo nó de rede tendo pelo menos uma antena de recepção compreende as etapas de: estimar um valor atual de pelo menos um primeiro tipo de informação do estado de canal para pelo menos um sub-canal dentro do canal a partir de sinais recebidos pela pelo menos uma antena de recepção, sobre o canal a partir da pelo menos uma antena de transmissão; determinar se o valor atual do primeiro tipo de informação de estado de canal varia a partir do valor previamente transmitido para o primeiro tipo de informação de estado de canal, por pelo menos, uma quantidade pré-determinada, e se sim, transmitir um indicador indicador indicativo do valor atual para o primeiro tipo de informação de estado de canal para o primeiro nó de rede.
