Abstract

método para transmissão de retorno de informação de estado de canal e equipamentos usuário. são descritos um método para transmissão de retorno de informação de estado de canal e equipamento usuário. o método compreende: sob um modo de transmissão, o equipamento usuário (ue) determinar os conteúdos portados pela informação de estado de canal de acordo com a informação de indicação, em que a informação de indicação compreende pelo menos um dentre o seguinte: indicador de classificação (ri), informação de indicação de qualidade de canal (cqi) e sinalização de configuração enviada por um e nodob de estação base; e o ue enviar a informação de estado de canal ao enodob. a presente invenção resolve o problema de que os conteúdos providos pela informação de estado de canal não são adequados para aqueles modos de transmissão sob os quais um mimo de usuários múltiplos e um mimo de usuário único podem ser comutados entre si, melhorando a aplicabilidade da informação de estado de canal.
