Abstract

RELATÓRIO DE INFORMAÇÕES DE ESTADO DE CANAL PARA OPERAÇÃO MULTI-TRP. A presente invenção refere-se a várias maneiras de relatar medições de informações de estado de canal (CSI) em uma configuração de múltiplos pontos de transmissão e recepção (multiTRP). Um UE pode realizar medições de informações de estado de canal (CSI) para um recurso de medição de canal (CMR) para o primeiro gNB e pelo menos um recurso de medição de interferência (IMR) para o pelo menos um segundo gNB, determinar uma configuração para um relatório de CSI para as medições de CSI incluindo uma medição de indicador de qualidade de canal (CQI) para o CMR e pelo menos um IMR e transmitir o relatório de CSI a pelo menos um dentre o primeiro gNB e o pelo menos um segundo gNB.
