Abstract

é discutido o sinal de referência de informação de estado de canal híbrido (csi), (csi-rs), para múltiplas entradas, múltiplas saídas (fd-mimo) de dimensão total em que uma estação base configura um primeiro recurso de csi-rs para o csi-rs não pré-codificado e um segundo recurso de csi-rs para o csi-rs com conformação de feixes. o primeiro e o segundo recursos de csi-rs estão associados com o mesmo processo de csi em uma operação de csi-rs híbrido. o ue fornece um primeiro relatório de csi incluindo um primeiro indicador de classificação e indicador de matriz de pré-codificação (pmi) com base na medição de csi-rs não pré-codificado. a estação base pode utilizar este primeiro relatório de csi para conformação de feixes do csi-rs com conformação de feixes. o ue fornece adicionalmente um segundo relatório de csi incluindo uma segunda classificação, um segundo pmi e cqi com base na medição de csi-rs com conformação de feixes. aspectos adicionais podem proporcionar a uma estação base agregar múltiplas configurações de recursos de csi-rs duas portas dentro de uma configuração de recursos de csi-rs multiporta única que pode ser dinamicamente compartilhada entre diferentes ues.
