Non-terrestrial networks (NTN) related RF and co-existence aspects
The present document covers the RF and co-existence aspects of the work item “Solutions for NR to support non-terrestrial networks (NTN)” [2]
The objectives for the study are the following:
-	Study and specify adjacent channel co-existence scenarios of Non-terrestrial networks (NTN).
-	Study and specify needed generic RF core requirements for the network and the UE such that adjacent channel co-existence scenarios are met.
NOTE:	Satellite operation is used as complementarily to Terrestrial Network operation, and in separate location when satellite operates in an adjacent channel/band of terrestrial network. For instance, NTN satellite UE is assumed to connect and transmit to the satellite when it is outside a Terrestrial Network operating in an adjacent channel/band. The satellite beam might still overlap the terrestrial network.
