Abstract

PROJETO DE INFORMAÇÕES DE ESTADO DE CANAL (CSI) DE MÚLTIPLAS SAÍDAS (MIMO) DE NEW RADIO (NR) PARA PARTE DE LARGURA DE BANDA (BWP) PEQUENA. Alguns aspectos desta revelação se referem a aparelhos e métodos para implementar um projeto de sinalização de capacidade para melhoria de múltiplas entradas e múltiplas saídas (MIMO) da versão 15 (Rel-15) e/ou versão 16 (Rel-16) do projeto de parceria de terceira geração (3GPP). Por exemplo, sistemas e métodos são fornecidos para implementar projetos para informações de estado de canal (CSI) de MIMO de New Radio (NR) para uma parte de largura de banda (BWP) pequena e/ou um número pequeno de sub-bandas. Por exemplo, alguns aspectos se referem a um equipamento de usuário (EU) que inclui um transceptor configurado para se comunicar com uma estação-base e um processador comunicativamente acoplado ao transceptor. O processador recebe, a partir da estação-base, uma mensagem de configuração de relatório de CSI. O processador determina, com o uso da mensagem de configuração de relatório de CSI, que um número de blocos de recursos físicos (PRBs) de uma BWP associada à mensagem de configuração de relatório de CSI é menor que um número limite. O processador também gera e transmite um relatório de CSI para a BWP.
