Abstract

MÉTODOS REALIZADOS POR UM DISPOSITIVO SEM FIO PARA RELATAR INFORMAÇÕES DE ESTADO DE CANAL E POR UMA ESTAÇÃO BASE PARA HABILITAR O RELATO DE INFORMAÇÕES DE ESTADO DE CANAL, DISPOSITIVO SEM FIO, E, ESTAÇÃO BASE. São providos sistemas e métodos para realimentação de Informações de Estado de Canal (CSI) para esquemas de URLLC multi-TRP. Em algumas modalidades, um método realizado por um dispositivo sem fio para relato de CSI inclui: receber uma configuração para uma pluralidade de recursos de CSI-RS de Potência Diferente de Zero (NZP) de uma estação base; realizar medição de canal na pluralidade de recursos de CSI-RS de NZP; selecionar N da pluralidade de recursos de CSI-RS de NZP; realizar computações de CSI e/ou cálculo de parâmetros de CSI incluindo um ou mais dentre: um Indicador de Classificação (RI), N Indicadores de Matriz de Précodificação (PMIs) e um Indicador de Qualidade de Canal (CQI); e relatar os parâmetros de CSI calculados. Os parâmetros incluindo um ou mais dentre: um RI, N PMIs, um CQI juntamente com um ou mais dos seguintes como parte do relato de CSI: um único Indicador de Recurso de CSI-RS (CRI) indicando os N recursos de CSI-RS de NZP selecionados; N CRIs indicando os N recursos de CSI-RS de NZP selecionados; e nenhum CRI.
