1 Scope
The purpose of this report is to identify specialist technical terms used within the 3GPP project for the purposes of
specifying service requirements. The motivations for this are:
- To ensure that editors use terminology that is consistent across specifications.
- To provide a reader with convenient reference for technical terms that are used across multiple documents.
- To prevent inconsistent use of terminology across documents.
This document is a collection of terms, definitions and abbreviations related to the baseline documents defining 3GPP
objectives and systems framework. This document provides a tool for further work on 3GPP technical documentation
and facilitates their understanding.
The terms, definitions and abbreviations as given in this document are either imported from existing documentation
(ETSI, ITU or elsewhere) or newly created by 3GPP experts whenever the need for precise vocabulary was identified.
2 References
The following documents contain provisions which, through reference in this text, constitute provisions of the present
document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or
non-specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including
a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same
Release as the present document.

transmitter or transceiver; and
