Abstract

a fim de permitir que um ue receba um sinal de banda estreita transmitido usando recursos em banda para usar os sinais de referência de lte para auxiliar o ue na recepção do sinal de banda estreita usando uma implantação em banda, a rotação de fase empregada pela estação de base pode ser fixa relativamente a uma posição de referência conhecida no tempo. um aparelho para comunicação sem fio em uma estação de base pode determinar um deslocamento de fase para um sinal de banda estreita para transmissão usando recursos de banda larga, o deslocamento de fase tendo uma relação a um ponto de referência no tempo e transmitir o sinal de banda estreita usando o deslocamento de fase determinado. um aparelho para comunicação sem fio em um ue pode receber um sinal de banda estreita tendo uma localização de frequência dentro de um sinal de banda larga e rotacionar um símbolo do sinal de banda larga por um deslocamento de fase por símbolo tendo uma relação do deslocamento de fase para um ponto de referência no tempo.
