Abstract

MÉTODOS DE PREPARAÇÃO DE DERIVADOS QUIRAIS DE BENZODIAZEPINONA. A presente invenção refere-se a um método de comunicação sem fio por um equipamento de usuário (UE) que recebe um decodificador de informações de estado de canal (CSI) e codificador de CSI a partir de uma estação base em um canal de controle de downlink físico (PDSCH) ou um elemento de controle do controle de acesso ao meio (MAC-CE). O método também inclui treinar o decodificador de CSI e codificador de CSI com base em condições de canal e interferência observadas para obter coeficientes de decodificador atualizados e coeficientes de codificador atualizados. O método adicionalmente inclui receber uma indicação de recursos para transmissão dos coeficientes de codificador atualizados e coeficientes de decodificador atualizados. O método inclui transmitir os coeficientes de decodificador atualizados e coeficientes de codificador atualizados para a estação base de acordo com a indicação de recursos. Além disso, o método inclui receber um decodificador de CSI atualizado e um codificador de CSI atualizado a partir da estação base para treinamento adicional.
