### NR UE
At UE side, there are two main parameters to cope with the large NTN propagation delay, cellSpecificKoffset and ta-Common.
`cellSpecificKoffset` is the same as for gNB and can be provided to the UE via command line parameter `--ntn-koffset`.
`ta-Common` is a common timong advance and can be provided to the UE via command line parameter `--ntn-ta-common` in milliseconds.
So an example NR UE command for FDD, 5MHz BW, 15 kHz SCS, GEO satellite 5G NR NTN is this:
```
cd cmake_targets
sudo ./ran_build/build/nr-uesoftmodem --band 66 -C 2152680000 --CO -400000000 -r 25 --numerology 0 --ssb 48 --sa --rfsim --rfsimulator.prop_delay 238.74 --ntn-koffset 478 --ntn-ta-common 477.48
```
