Abstract

1//1 resumo “relatório de csi para um conjunto de recursos csi-rs” trata-se de um método implementado por um terminal sem fio para relatar informação de estado de canal a uma rede de comunicação sem fio. o terminal sem fio recebe símbolos de referência em um conjunto de recursos de símbolo de referência de informação de estado de canal (csi-rs), e determina uma classificação de transmissão comum para o conjunto de recursos csi-rs, com base nos símbolos de referência recebidos em um subconjunto desses recursos csi-rs. o terminal então gera um retorno de csi como uma função da classificação de transmissão comum, e transmite o retorno de csi para a rede de comunicação. o retorno de csi pode incluir diferentes classificações de transmissão para diferentes recursos csi-rs, cada um determinado como uma função da classificação de transmissão comum. um método complementar no qual um nó de rede usa tal retorno de csi para executar a adaptação de rede para o conjunto de recursos csi-rs é também descrito.
