Research on key technologies in the 52.6GHz-71GHz frequency band

Liang Qiao, Bibo Liu

Abstract

In the 3GPP release 17 NR system, the 52.6GHz-71GHz frequency band is standardized. In order to transmit the information
with larger bandwidth, the Sub-Carrier Spacing (SCS) of 480KHz and 960KHz are newly defi ned. At the same time, this frequency band
belongs to unlicensed frequency band in some countries or regions, and some signals need to comply with the transmission regulations of
unlicensed frequency band. Based on this, this topic mainly focuses on the impact of the newly introduced two Sub-Carrier Spacing and the
regulations on the frequency band under the existing NR system.
