3 Definitions of terms, symbols and abbreviations p. 12

3.1 Terms p. 12

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.

"Carrier-off" state:

radio state in which the NTN VSAT may transmit but does not transmit any carrier.

"Carrier-on" state:

Radio state in which the NTN VSAT may transmit and transmits a carrier.

Co-polarized transmission:

when the DUT transmission antenna polarization is aligned with test antenna polarization.

Cross-polarized transmission:

when the DUT transmission antenna polarization is aligned with the tangent of the test antenna polarization.

"Emissions disabled" state:

Radio state in which the Mobile VSAT is not emitting (e.g. before system monitoring pass, before the control channel is received, when a failure is detected, when a Mobile VSAT is commanded to disable, and when the Mobile VSAT is in a location requiring cessation of emissions).

Enhanced channel raster:

channel raster with a 10 kHz granularity in bands with a 100 kHz channel raster.

Feeder link:

A radio link from an earth station at a given location to a space station, or vice versa, conveying information for a space radiocommunication service other than for the fixed-satellite service. The given location may be at a specified fixed point, or at any fixed point within specified areas.

Fixed Satellite Service:

A radiocommunication service between earth stations at given positions, when one or more satellites are used; the given position may be a specified fixed point or any fixed point within specified areas; in some cases this service includes satellite-to-satellite links, which may also be operated in the inter-satellite service; the fixed-satellite service may also include feeder links for other space radiocommunication services.

Fixed VSAT:

VSAT used in FSS system at given position; the given position may be a specified fixed point or any fixed point within specified areas.

Geostationary satellite:

A geosynchronous satellite whose circular and direct orbit lies in the plane of the Earth's equator and which thus remains fixed relative to the Earth; by extension, a geosynchronous satellite which remains approximately fixed relative to the Earth.

Geostationary-Satellite Orbit:

The orbit of a geosynchronous satellite whose circular and direct orbit lies in the plane of the Earth's equator.

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.

Geosynchronous satellite:

An earth satellite whose period of revolution is equal to the period of rotation of the Earth about its axis.

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 SAN.

NTN VSAT:

a UE operating in FR2-NTN which could be a Fixed VSAT or a Mobile VSAT.

Plane perpendicular to the GSO arc:

The plane that is perpendicular to the "plane tangent to the GSO arc," as defined below, and includes a line between the earth station in question and the GSO space station that it is communicating with (FCC 47 CFR 25.103).

Plane tangent to the GSO arc:

The plane defined by the location of an earth station's transmitting antenna and a line in the equatorial plane that is tangent to the GSO arc at the location of the GSO space station that the earth station is communicating with (FCC 47 CFR 25.103).

Satellite:

A space-borne vehicle embarking a transparent 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:

node providing NR user plane and control plane protocol terminations towards NTN satellite capable UE, and connected via the NG interface to the 5GC. It encompasses a transparent payload on board a NTN platform, with satellite-gateway and gNB functions.

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.
