Terminology may take the form of an independent 3GPP terminology deliverable (a vocabulary or a nomenclature) or be included in a "Definitions" clause in a 3GPP TS or 3GPP TR that also deals with other aspects.

Any term which is not self-explanatory or commonly known and which can be differently interpreted in different contexts shall be clarified by defining the relevant concept. Common dictionary or current technical terms shall be included only if they are used with a specific meaning in the relevant context. Trade names (brand names) and archaic and colloquial terms shall be avoided. Deprecated terms may be included after the preferred term but their nature shall be indicated (by adding the word deprecated, see clause C.3.3). In an independent terminology deliverable, the concepts defined shall be restricted to the field corresponding to the scope of 3GPP. In other 3GPP TSs or 3GPP TRs, only such concepts shall be defined as are used in those 3GPP TSs or 3GPP TRs, apart from any additional concepts and their terms that may be deemed necessary for the understanding of these definitions.

Before a term and a definition are established for a concept, it should be ascertained that no other term and definition for that concept exist in another 3GPP TS or 3GPP TR. If the concept is used in several 3GPP TSs or 3GPP TRs, it should be defined in the most general of those standards, or in an independent terminology deliverable. The other 3GPP TSs or 3GPP TRs should then refer to this deliverable, without repeating the definition of the concept. When the repetition of a definition is necessary, an informative reference shall be made to the document (3GPP TS or 3GPP TR or other) from which it is reproduced (see clause 6.6.6.5). If a term and a definition for a concept are established in one 3GPP TS or 3GPP TR, the introduction in another 3GPP TS or 3GPP TR of a different term (synonym) for the defined concept is strongly deprecated.

A definition shall not take the form of, or contain, a requirement. The form of a definition shall be such that it can replace the term in context. Additional information shall be given only in the form of examples or notes (see clause C.3.9). A definition given without an indication of its applicability may be taken as representing the general meaning of the term. Special meanings in particular contexts shall be indicated by designating the subject field (see clause C.3.6).

An independent terminology deliverable containing terms and definitions should be preferably classified according to the hierarchy of the concepts. The terms and definitions of general concepts shall precede those of less general concepts. If a mixed system of concepts is used in which several groupings (according to different criteria) appear, each grouping shall be kept separate and the relevant criteria shall be indicated. The grouping of terms shall be evident from their numbering.

The preferred term (set in bold type) shall be placed on a new line, (after its reference number, if used), starting with a lower-case letter except for any capital letters required by the normal written form in running text. The definition shall follow, after a colon and a space. EXAMPLE: delamination: separation of two adjacent plies resulting from a lack of adhesion

Admitted terms (set in normal type in the printed publication) shall each be placed on a new line, after the preferred term. EXAMPLE 1: serializer; parallel-serial converter dynamicizer: functional unit that converts a set of simultaneous signals into a corresponding time sequence of signals Symbols shall be given following any admitted term(s). Information regarding the units applicable to a quantity shall be given in a note. EXAMPLE 2: resistance; R: electric difference divided by current when there is no electromotive force in the conductor Deprecated, obsolete and superseded terms (in normal type) shall each be placed after the recommended term, after any symbols, and shall be followed by an indication of their status, in parentheses. EXAMPLE 3: radix; base (deprecated): positive integer by which the weight of any digit place is multiplied to obtain the weight of the digit place with the next higher weight

Terms shall in general be presented in their basic grammatical form, i.e. nouns in the singular, verbs in the infinitive.

Void.

If a term is used to represent several concepts, the subject field to which each concept belongs shall be indicated between angle brackets, before the definition. EXAMPLE: die, noun: [extrusion] metal block with a shaped orifice through which plastic material is extruded die, noun: [moulding] assembly of parts enclosing the cavity from which the moulding takes its form die, noun: [punching] tool to punch sheet or film material

Void.

Parentheses and square brackets shall be used only if they constitute part of the normal written form of the term. They shall not be used to show alternative terms. EXAMPLE:

Examples of term usage, and notes concerning entries, shall be presented as shown below. radix; base (deprecated): [radix numeration system] positive integer by which the weight of any digital place is multiplied to obtain the weight of the digit place with the next higher weight EXAMPLE:
