Abstract

é discutido um esquema de sinal de referência de informação de estado de canal (csi) (csi-rs) classe b híbrido que configura um recurso de csi-rs com conformação de feixes de célula comum para rastreamento de feixes e outro recurso de csi-rs com conformação de feixes específico de ue para feedback de csi. o recurso de csi-rs com conformação de feixes de célula comum pode ser transmitido em uma periodicidade mais longa e compartilhado por equipamentos de usuário (ues) na célula. a conformação de feixes pode ser submetida a ciclos através de um conjunto de pesos predefinidos transparentes para o ue. o csi-rs com conformação de feixes específico de ue pode ser transmitido em uma periodicidade mais curta e pode ser ativado dinamicamente para permitir o compartilhamento de recursos entre vários ues. os ues reportarão uma csi para o recurso de csi-rs com conformação de feixes de célula comum que fornece um indicador de qualidade para o feixe de célula comum associado e é utilizado pela estação base para determinar o peso de pré-codificação para o recurso de csi-rs com conformação de feixes específico de ue. ambos os recursos podem ser configurados com diferentes conjuntos de parâmetros, como número de portas, tipo de livro-código e parâmetros de relatório de csi.
