Abstract

são descritas técnicas que apresentam a divisão virtual de símbolo para transmissões sem fio de uplink e/ou downlink. um transmissor sem fio, tal como um ue ou uma estação base, pode identificar um sinal piloto e uma carga útil a ser transmitida em um símbolo completo. o transmissor pode formatar o sinal piloto e a carga útil em sub-símbolos separados que estão aninhados dentro do primeiro símbolo completo, com cada sub-símbolo incluindo um sub-símbolo associado de prefixo cíclico, e o símbolo completo incluindo um prefixo cíclico de símbolo completo.
