5G NR Supplementary Downlink (SDL)

Hello All.

:white_check_mark: In 5G NR, to increase the capacity and data rate especially in the low frequency bands (below 1 GHz), a downlink carrier in unpaired spectrum as SDL carrier can be added to aggregate with a carrier, e.g. in the paired spectrum (FDD).

:white_check_mark: Here I try to depict a scenario that a SDL carrier in n75 (1500 MHz) is aggregated with a carrier in n20 (800 MHz).
