Supplementary uplink with LTE coexistence adjacent to frequency division duplex spectrum for radio networks

The described technology is generally directed towards using a frequency-separated band as a supplementary uplink band for a new radio downlink band that cannot operate as a time division duplex band and otherwise has no paired uplink band. The paired bands are separated in frequency, yet operate in the time division duplex mode. The supplementary uplink for New Radio facilitates coexistence with LTE in the frequency division duplex spectrum.
