1. A method of enabling communication between a user equipment (UE) and a non-terrestrial network (NTN), comprising:
receiving, at the UE, satellite position data of the NTN;
determining, at the UE, a UE position;
calculating, at the UE, a first distance between the UE position and the satellite position data;
calculating, at the UE, a timing advance based on the first distance;
receiving, at the UE, a Koffset value, wherein the Koffset value is transmitted to the UE by the NTN; and
applying, at the UE, one or both of the timing advance and Koffset to configure transmission or reception of communication with the NTN.
