Abstract

trata-se de métodos, sistemas e dispositivos para comunicação sem fio estabelecidos na indicação de informações de comunicação com o uso de uma correlação entre os sinais de sincronização transmitidos por uma estação-base para a aquisição de célula. as informações de comunicação podem incluir um parâmetro de temporização de canal físico como periodicidade de sincronização, uma periodicidade de canal de difusão físico (pbch), uma periodicidade de varredura de feixe ou um tipo de prefixo cíclico (cp). as informações de comunicação podem indicar também a presença de uma transmissão de canal de difusão físico (pbch) ou de uma transmissão de sinal de referência de mobilidade (mrs). a correlação pode ser uma mudança de fase entre múltiplos sinais ou pode se basear nas matrizes de pré-codificação usadas durante o processamento de transmissão dos sinais de sincronização através de subportadoras e portas de antena.
