Abstract

resumo patente de invenção: "dispositivo, rede e método para a utilização de um sinal de referência de descoberta do enlace descendente". a presente invenção refere-se a equipamentos do usuário que podem conseguir uma rápida sincronização do canal quando estabelecendo uma conexão com estações de base transitando de um modo de espera para um modo ativo usando os resultados do processamento do sinal de recurso de descoberta (drs) e os resultados do processamento do sinal de referência de célula (crs) para estabelecer a sincronização do canal com uma porta de antena de crs. mais especificamente, o equipamento do usuário pode ser notificado que a porta de antena do crs e a porta de antena do drs estão quase localizadas juntas (qcl) e então usar os resultados do processamento do drs em conjunto com os resultados do processamento do crs para obter uma sincronização de canal mais rápida com uma porta de antena do crs. isso pode ser particularmente benéfico quando a bs alvo transita de um modo de espera para um modo ativo, de modo a aceitar a transição do equipamento do usuário.
