Abstract
Se describen técnicas para seleccionar par de raíz para secuencias Zadoff-Chu para preámbulo de acceso aleatorio y para señalar uno o más valores asociados con el par de raíz a un equipo de usuario (UE) por una estación base. Los métodos de selección de par de raíz descritos para el preámbulo del canal de acceso aleatorio físico (PRACH) de dos raíces pueden permitir que las diferencias pico recibidas en el UE desde diferentes compensaciones de frecuencia (FOs) se separen incluso considerando el error en el lado del UE. Las técnicas de selección pueden mejorar el rendimiento de PRACH FO y la estimación de compensación de tiempo (TO).
