For wireless communications, lower frequencies provide better coverage. Currently, almost all countries use spectrum below 6 GHz for IMT systems. Besides achieving high data rates, it is also necessary to guarantee wide-area coverage and outdoor-to-indoor coverage in 5G. Therefore, spectrums below 6 GHz form a very important part of the 5G spectrum solution. In China, potential 5G spectra below 6 GHz include the following aspects.
