Abstract

MÉTODO DE DETERMINAÇÃO DE SINCRONIZAÇÃO DE UM EQUIPAMENTO DE USUÁRIO EM UMA REDE DE COMUNICAÇÃO SEM FIO, E, EQUIPAMENTO DE USUÁRIO OPERATIVO EM UMA REDE DE COMUNICAÇÃO SEM FIO. Equipamento de Usuário em uma rede de comunicação sem fio considera a largura de banda de canal de enlace descendente na delimitação de sincronização (OoS) e em limites de sincronização (IS) durações de filtro. Adicionalmente, o UE pode considerar configuração de antena de transmissor isto é, o número de antenas de transmissão em um sistema MIMO - na delimitação do OoS e limites de 18. O UF determina que é OoS quando uma métrica de qualidade de canal de enlace descendente, filtrada, monitorada, tal como símbolo de referência SINR, está abaixo do limite de OoS.
