Abstract
A method of enabling communication between a user equipment (UE) and a non-terrestrial network (NTN), is described. The UE may be able to calculate a timing advance compensation. The timing advance compensation may be a differential or full timing advance compensation. An offset value, Koffset, may be indicated to the UE. The Koffset value may be used for timing relationships.

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, and
- applying, at the UE, one or both of the timing advance and Koffset to configure transmission or reception of communication with the NTN.
A system that enables communication between a user equipment (UE) and a non-terrestrial network (NTN), the system configured to:
- receive, at the UE, satellite position data of the NTN,
- determine, at the UE, a UE position,
- calculate, at the UE, a first distance between the UE position and the satellite position data,
- calculate, at the UE, a timing advance based on the first distance,
- receive, at the UE, a Koffset value, and
- apply, at the UE, one or both of the timing advance and the Koffset to configure transmission or reception of communication with the NTN.
