Abstract

comunicações de banda estreita em um sistema de comunicações sem fio podem incluir um sinal de sincronização comum, tal como um sinal de sincronização primário (pss), sinal de sincronização secundário (sss) ou canal de difusão físico (pbch). o conteúdo do sinal de sincronização comum pode indicar uma localização de transmissões de dados de banda estreita em uma região de banda estreita de uma largura de banda de sistema. a localização da região de banda estreita pode estar em banda dentro de uma ou mais transmissões de banda larga, dentro de uma largura de banda de banda de guarda adjacente à largura de banda de transmissões de banda larga, ou dentro de uma largura de banda autônoma que não é adjacente às transmissões de banda larga. o sinal de sincronização comum pode estar localizado dentro de uma frequência de busca predefinida e pode incluir um canal de sincronização de ancoragem presente em certos recursos de recursos de comunicações de banda estreita alocados. os recursos de região de dados de banda estreita podem ser distribuídos em outras porções dos recursos de comunicações de banda estreita, e podem ser alocados para usuários diferentes para fornecer diversidade de transmissão.
