摘要

5G毫米波的载波频率高，初始接入频偏大，可能导致收发端时频同步不准确及物理小区标识检测错误问题。针对此问题，分析并仿真了5G毫米波在高频偏下基于波束扫描方式发送同步信号的小区搜索方案。提出了一种在基站侧使用DFT码本发送多方向的同步信号块，在终端用全向天线接收多波束信号并使用一系列同步算法完成时间、频率同步及物理小区标识检测的5G毫米波小区搜索过程。仿真结果表明，所提预存整数倍频偏与接收信号互相关的主同步信号检测算法在5G毫米波信道有良好的小区搜索性能。

Abstract

Due to the high carrier frequency of the 5G millimeter wave

a large initial access frequency may cause inaccurate time-frequency synchronization at the transmitting and receiving ends and incorrect detection of the physical layer cell identifier.A cell search scheme for 5G millimeter waves to send synchronization signals in a beam sweeping mode at high frequencies was analyzed and simulated.Specifically

a multi-directional synchronization signal block sent by a DFT codebook at the base station side was proposed.The terminal used an omnidirectional antenna to receive multi-beam signals and used a series of synchronization algorithms to complete time

frequency synchronization

and physical layer cell identification.Simulation results show that the proposed main synchronization signal detection algorithm with cross-correlation of pre-stored integer frequency offset and received signal has good cell search performance on 5G millimeter-wave channels.
