Intellectual Property Rights
Essential patents
IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web

ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no
right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does

Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Speech and multimedia Transmission
Quality (STQ).
While - at the time of publication - there is no final, complete specification of 5G, its essential properties are well
defined. The present document addresses the question if, and potentially how, these properties require an extension of
the current portfolio of QoS metrics which describe the technology from a strictly end user, service-oriented point of
view. For this purpose, a systematic analysis of 5G features and their relation to QoS is presented.
Modal verbs terminology
In the present document "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be
interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Executive summary
The present document addresses the question if the inventory of QoS parameters needs to be expanded to adequately
cover the upcoming 5G standard. Thorough examination leads to the conclusion that, as 5G does not provide any new
type of service, no such extension is intrinsically required. Likewise, the inventory of methodologies used for
performance testing is adequate. However, due to new properties of 5G such as network slicing and dynamic
prioritization of services, the role of careful design of test scenarios will be more prominent.
In particular, the understanding of a packet data network as a static medium ("bit pipe") becomes even less applicable
than in existing technologies. As a consequence, predictions derived from testing with a particular use case, which is in
general a particular set of parameters for a generic test case, become less reliable. Also, the range of comparability
between QoS parameters which have been derived with different parameter sets may become smaller, increasing the
need for careful design of test conditions, thorough understanding of methodologies, and comprehensive documentation
of tests.

Introduction
5G is the upcoming new generation of mobile network technology. It is characterized by an increase in general
performance on the transport plane, i.e. data rates and latency, but also by a range of new features such as network
slicing and dynamic prioritization of data transport. The present document addresses the question if the current
inventory of QoS parameters is adequate to cover and serve the 5G ecosystem, or if new services have to be considered
or QoS parameters of existing services have to be adapted.

1 Scope
The present document summarizes the results of an analysis of the impact of the upcoming 5G on existing QoS metrics,
and the question if extensions or modifications of the portfolio of QoS parameters portfolio are required to capture
respective properties of 5G.
The analysis starts with a summary of features and properties of 5G which can be expected to be relevant for QoS
assessment.
The first question addressed is if there are features of the 5G roadmap - as far as technically stable as of the time of
publication, or reasonably stable projections - which constitute new services which would then require new sets of QoS
parameters. The second question is in what way projected 5G properties may require adaptations with respect to
measurement methodologies, computation, or usage of existing QoS parameters.

4 QoS relevant innovation in 5G
4.1 Overview
This clause provides a quick overview of the most important QoS related aspects of 5G. The following clause will then
present a systematic, step-by-step analysis of 5G features (according to 3GPP TS 22.261 [i.1]) and their relevance for
QoS and QoE.
4.2 Central features
5G features can, from a QoS and QoE point of view, be divided into two categories:
• Quantitative improvements such as an increase in available data rate or reduction of latency.
• Qualitative expansions which by themselves constitute new types of service by themselves.
Quantitative improvements can act, in a more or less direct way, as enablers for new types of services. They do,
however, carry respective properties. For instance, an ecosphere around multimedia services such as Video Streaming
will only evolve if the medium provides a certain minimum bandwidth. Likewise, an ecosphere of smartphone based
applications - and in particular the rich OTT world that can observed at times of the publication of the present document
- is linked to availability of devices as well as of sufficie
