1 Scope
This document is related to the technical report for this study item "Scenarios and Requirements for Next Generation
Access Technologies" [1]. The objective of the study item is to identify the typical deployment scenarios associated
with attributes such as carrier frequency, inter-site distance, user density, maximum mobility speed, etc, and to develop
requirements for next generation access technologies for the identified deployment scenarios taking into account, but
not limited to, the ITU-R discussion on IMT-2020 requirements.
This document contains scenarios and requirements for next generation access technologies, which can be used as not
only guidance to the technical work to be performed in 3GPP RAN WGs, but also input for ITU-R to take into account
when developing IMT-2020 technical performance requirements.

4 Introduction
At the 3GPP TSG RAN #70 meeting, the Study Item description on "Scenarios and Requirements for Next Generation
Access Technologies" was approved [1].
The justification of the Study Item was that a fully mobile and connected society is expected in the near future, which
will be characterized by a tremendous amount of growth in connectivity, traffic volume and a much broader range of
usage scenarios. Some typical trends include explosive growth of data traffic, great increase of connected devices and
continuous emergence of new services. Besides the market requirements, the mobile communication society itself also
requires a sustainable development of the eco-system, which produces the needs to further improve system efficiencies,
such as spectrum efficiency, energy efficiency, operational efficiency and cost efficiency. To meet the above ever-
increasing requirements from market and mobile communication society, next generation access technologies are
expected to emerge in the near future. A study item to identify typical deployment scenarios for next generation access
technologies and the required capabilities in each corresponding deployment scenarios should be considered.
5 Objectives
In order to meet the deployment scenarios and requirements, studies for next generation access technologies should be
carried out in at least, but not limited to, the following areas, designs for next generation access technologies RAN
should strive for enough flexibility to support current envisaged and future requirements for the different use cases, e.g.,
from SA1 3GPP TR 22.891 [3], i.e., to support for wide range of services.

6 Scenarios
6.0 General
This subsection briefly introduces the three usage scenarios defined by ITU-R IMT for 2020 and beyond [4] is
envisaged to expand and support diverse families of usage scenarios and applications that will continue beyond the
current IMT. Furthermore, a broad variety of capabilities would be tightly coupled with these intended different usage
scenarios and applications for IMT for 2020 and beyond. The families of usage scenarios for IMT for 2020 and beyond
include:
- eMBB (enhanced Mobile BroadBand)
- mMTC (massive Machine Type Communications)
- URLLC (Ultra-Reliable and Low Latency Communications)
6.1 Deployment scenarios
Deployment scenarios for eMBB, mMTC and URLLC are described in this TR. Other deployment scenarios related to
eV2X (enhanced Vehicle to Everything) services are also described in this TR. Not all requirements apply to all
deployment scenarios described in the TR. The mapping between requirements and deployment scenarios is described
per KPI in Chapter 7.However, some of eMBB deployment scenarios may possibl
