3.1 Terms

For the purposes of the present document, the terms given in 3GPP TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 [1].

Multi-USS capability: The possibility for a UAV to change USS during flight.

NOTE: A UAV with Multi-USS capability can be controlled by more than one USS during a flight, but at any given time, the UAV is under the control of only one USS.

Multi-USS policy: The configuration provided by a UAS application specific server to assist at change of USS.

Remote Identification (Remote ID) of UAS: The ability of a UAS to provide identification and tracking information that can be received by other parties, to facilitate advanced operations for the UAS (such as Beyond Visual Line of Sight operations as well as operations over people), assist regulatory agencies, air traffic management agencies, law enforcement, and security agencies when a UAS appears to be flying in an unsafe manner or where the UAS is not allowed to fly.

UAS Service Supplier (USS): An entity that provides services to support the safe and efficient use of airspace by providing services to the operator / pilot of a UAS in meeting UTM operational requirements. A USS can provide any subset of functionality to meet the provider’s business objectives (e.g., UTM, Remote Identification). In the scope of this specification, the term USS refers to both USS and USS/UTM.

UAV: The Uncrewed Aerial Vehicle (also called remotely piloted aircraft or drone) of a UAS.

For the purposes of the present document, the following terms given in 3GPP TS 22.125 [2] apply

Command and Control (C2) Communication

Uncrewed Aerial System (UAS)

UTM-Navigated C2 communication

3.2 Abbreviations

For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 [1] and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in 3GPP TR 21.905 [1].
