Abstract

RELATÓRIO DE INFORMAÇÃO DE ESTADO DE CANAL. Aparelhos, métodos e sistemas são divulgados para relatório de informação de estado de canal. Um método (900) inclui receber (902) informação de configuração de relatório de informação de estado de canal. A informação de configuração de relatório de informação de estado de canal inclui: informação indicando uma ou mais configurações de recursos de sinal de referência de informação de estado de canal associadas a um ou mais conjuntos de recursos de sinal de referência de informação de estado de canal para medições de canal, medições de interferência ou uma combinação das mesmas; e informação indicando que a realimentação de informação de estado de canal correspondente a múltiplos pontos é usada. Cada ponto dos múltiplos pontos está associado a um recurso de sinal de referência de informação de estado de canal de potência diferente de zero. O método (900) inclui realizar (904) medições de canal usando o conjunto de recursos de sinal de referência de informação de estado de canal. O método (900) inclui gerar (906) um conjunto de relatórios de informação de estado de canal com base na informação de configuração de relatório de informação de estado de canal.
