Abstract

Una WTRU puede comprender un sistema de circuitos configurado para determinar secuencias de DMRS de longitud 12, 18 y 24 para la modulación de OFDM extendida por DFT de PI/2 BPSK. Las secuencias se optimizan para PAPR, CM, planicidad de frecuencia, correlación cruzada y para el cálculo de canal (correlación cíclica).
