3 Definitions of terms, symbols and abbreviations p. 11

3.1 Terms p. 11

For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.

Geosynchronous Earth Orbit:

Earth-centered orbit at approximately 35786 kilometres above Earth's surface and synchronised with Earth's rotation. A geostationary orbit is a non-inclined geosynchronous orbit, i.e. in the Earth's equator plane.

Low Earth Orbit:

Orbit around the Earth with an altitude between 300 km, and 1500 km.

Non-terrestrial networks:

Networks, or segments of networks, using an airborne or space-borne vehicle to embark a transmission equipment relay node or base station.

Satellite:

A space-borne vehicle embarking a bent pipe payload or a regenerative payload telecommunication transmitter, placed into Low-Earth Orbit (LEO), Medium-Earth Orbit (MEO), or Geostationary Earth Orbit (GEO).

Satellite Access Node:

see definition in TS 38.108.

UE transmission bandwidth configuration:

Set of resource blocks located within the UE channel bandwidth which may be used for transmitting or receiving by the UE.
