Abstract

este pedido fornece um método para configurar uma banda de relatório de informação de estado de canal, um método de relatório e um aparelho correspondente. o método inclui: determinar um tamanho de sub-banda de informação de estado de canal baseado em uma parte de largura de banda (bwp); e determinar, uma quantidade de sub-bandas de informação de estado de canal incluídos em uma banda de comunicação de informação de estado de canal, com base na largura de banda de componente de portadora (cc) ou a parte da largura de banda (bwp) ou uma largura de banda de sinal de referência de informação de estado de canal (csi-rs), e o tamanho de sub-banda de informação de estado de canal. o método inclui ainda: determinar uma quantidade real de blocos de recurso incluídos em uma sub-banda inicial e uma quantidade real de blocos de recurso incluídos em uma sub-banda final na sub-banda de informação de estado de canal. a implementação deste pedido torna a configuração de uma quantidade e tamanho de sub-banda em uma banda de relatório de csi mais flexível e reduz a complexidade do endereçamento do terminal.
