Abstract

PLANOS DE NUMERAÇÃO E BASE DE TEMPO DE SISTEMA PARA REDES FUTURAS. A presente invenção refere-se a que definindo mais opções de SCS e opções de Transformada Discreta de Fourier (DFT) para transmissões em redes futuras, é originada causa para selecionar entre as opções, com aspectos do canal como orientação para a seleção. Além disso, projetos de CP podem ser definidos para uso com as novas opções de SCS e as novas opções de DFT junto com métodos de seleção de um projeto de CP apropriado para uma situação particular. Os novos projetos de CP podem ser mostrados ter cabeçalho de CP melhores quando comparados com os projetos de CP conhecidos usados para combinações conhecidas de uma opção de SCS com uma opção de tamanho de FFT. Opções de projeto de frequência de amostragem novas e opções de cronometragem básica de sistema novas podem também ser definidas, junto com métodos de realização de seleções apropriadas a partir dessas opções. Sinalização de controle usando camadas superiores podem ser usadas para distribuir opções de configuração que incluem opções de SCS múltiplas, opções de duração de CP, opções de frequência de amostragem e opções de tamanho de DFT por sub-banda. Mais tarde, sinalização da camada 1 pode ser usada para especificar uma opção particular dentre as múltiplas opções.
