Abstract
BAIXA SOBRECARGA E ALTA PRECISÃO DE FEEDBACK DE ESTADO DO CANAL USANDO REDES NEURAIS. Uma estação base pode pré-codificar um primeiro sinal de referência usando um primeiro pré-codificador (P1) e pelo menos um segundo sinal de referência usando pelo menos um segundo pré-codificador (P2). Pelo menos dois UEs podem medir o primeiro sinal de referência e o pelo menos um segundo sinal de referência, e transmitir feedback de estado do canal com base na medição (m11 e m12 para um primeiro UE, e m21 e m22 para um segundo UE). O feedback de estado do canal pode compreender informações do estado do canal comprimidas por pelo menos uma rede neural. A estação base pode derivar um pré-codificador de nível superior (W) para transmissão de downlink de múltiplas entradas e múltiplas saídas (MIMO) para pelo menos dois UEs.,
