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 possibly be reused to evaluate mMTC and
URLLC, or some specific evaluation tests (e.g., link-level simulation) can be developed to check whether the
requirements can be achieved.
High-level descriptions on deployment scenarios including carrier frequency, aggregated system bandwidth, network
layout / ISD, BS / UE antenna elements, UE distribution / speed and service profile are proposed in this TR. It is
assumed that more detailed attributes and simulation parameters, for example, the channel model, BS / UE Tx power,
number of antenna ports, etc. should be defined in the new RAT study item.

6.1.1 Indoor hotspot
The indoor hotspot deployment scenario focuses on small coverage per site/TRxP (transmission and reception point)
and high user throughput or user density in buildings. The key characteristics of this deployment scenario are high
capacity, high user density and consistent user experience indoor.
Some of its attributes are listed in Table 6.1.1-1.
Table 6.1.1-1: Attributes for indoor hotspot
Attributes Values or assumptions

Carrier Frequency Around 30 GHz or Around 70 GHz or Around 4 GHz

NOTE1
Aggregated system Around 30GHz or Around 70GHz: Up to 1GHz (DL+UL) NOTE3

elements NOTE4 Around 4GHz: Up to 8 Tx and Rx antenna elements
User distribution and 100% Indoor, 3km/h,
UE speed 10 users per TRxP
Service profile NOTE: Whether to use full buffer traffic or non-full-buffer traffic depends on the
evaluation methodology adopted for each KPI. For certain KPIs, full buffer traffic
is desirable to enable comparison with IMT-Advanced values.

NOTE1: The options noted here are for evaluation purpose, and do not mandate the deployment of these options or
preclude the study of other spectrum options. A range of bands from 24.25 GHz – 52.6 GHz identified for
WRC-19 are currently being considered and around 30 GHz is chosen as a proxy for this range. A range
of bands from 66 GHz – 86 GHz identified for WRC-19 are currently being considered and around 70
GHz is chosen as a proxy for this range. A range of bands from 3300 – 4990MHz identified for WRC-15
are currently being considered and around 4GHz is chosen as a proxy for this range.
NOTE2: The aggregated system bandwidth is the total bandwidth typically assumed to derive the values for some
KPIs such as area traffic capacity and user experienced data rate. It is allowed to simulate a smaller
bandwidth than the aggregated system bandwidth and transform the results to a larger bandwidth. The
transformation method should then be described, including the modelling of power limitations.
NOTE3: "DL + UL" refers to either of the following two cases:
1. FDD with symmetric bandwidth allocations between DL and UL.
2. TDD with the aggregated system bandwidth used for either DL or UL via switching in time-domain.
NOTE4: The maximum number of antenna elements is a working assumption. 3GPP needs to strive to meet the
target with typical antenna configurations.

Service profile NOTE: Whether to use full buffer traffic or non-full-buffer traffic depends on the
evaluation methodology adopted for each KPI. For certain KPIs, full buffer traffic
is desirable to enable comparison with IMT-Advanced values.

NOTE1: The options noted here are for evaluation purpose, and do not mandate the deployment of these options or
preclude the study of other spectrum options. A range of bands from 24.25 GHz – 52.6 GHz identified for
WRC-19 are currently being considered and around 30 GHz is chosen as a proxy for this range. A range
of bands from 3300 – 4990MHz identified for WRC-15 are currently being considered and around 4GHz
is chosen as a proxy for this range.
NOTE2: The aggregated system bandwidth is the total bandwidth typically assumed to derive the values for some
KPIs such as area traffic capacity and user experienced data rate. It is allowed to simulate a smaller
bandwidth than the aggregated system bandwidth and transform the results to a larger bandwidth. The
transformation method should then be described, including the modelling of power limitations.
NOTE3: Step 1 shall be used for the evaluation of spectral efficiency KPIs. Step2 shall be used for the evaluation
of the other deployment scenario dependant KPIs.
NOTE4: This value is the baseline and other number of micro TRxPs per macro TRxP (e.g., 6 or 10) is not
precluded.
NOTE5: The maximum number of antenna elements is a working assumption. 3GPP needs to strive to meet the
target with typical antenna configurations.
NOTE6: 10 users per TRxP is the baseline with full buffer traffic. 20 users per macro TRxP with full buffer traffic
is not precluded.

bandwidth than the aggregated system bandwidth and transform the results to a larger bandwidth. The
transformation method should then be described, including the modelling of power limitations.
NOTE3: Consider larger aggregated system bandwidth if 20MHz cannot meet requirement.
NOTE4: The maximum number of antenna elements is a working assumption. 3GPP needs to strive to meet the
target with typical antenna configurations.

6.1.4 Urban macro
The urban macro deployment scenario focuses on large cells and continuous coverage. The key characteristics of this
scenario are continuous and ubiquitous coverage in urban areas. This scenario will be interference-limited, using macro
TRxPs (i.e. radio access points above rooftop level).
Some of its attributes are listed in Table 6.1.4-1.

Service profile NOTE: Whether to use full buffer traffic or non-full-buffer traffic depends on the
evaluation methodology adopted for each KPI. For certain KPIs, full buffer traffic
is desirable to enable comparison with IMT-Advanced values.

NOTE1: The options noted here are for evaluation purpose, and do not mandate the deployment of these options or
preclude the study of other spectrum options. A range of bands from 24.25 GHz – 52.6 GHz identified for
WRC-19 are currently being considered and around 30 GHz is chosen as a proxy for this range. A range
of bands from 1427 – 2690MHz identified for WRC-15 are currently being considered and around 2GHz
is chosen as a proxy for this range. A range of bands from 3300 – 4990MHz identified for WRC-15 are
currently being considered and around 4GHz is chosen as a proxy for this range.
NOTE2: The aggregated system bandwidth is the total bandwidth typically assumed to derive the values for some
KPIs such as area traffic capacity and user experienced data rate. It is allowed to simulate a smaller
bandwidth than the aggregated system bandwidth and transform the results to a larger bandwidth. The
transformation method should then be described, including the modelling of power limitations.
NOTE3: The maximum number of antenna elements is a working assumption. 3GPP needs to strive to meet the
target with typical antenna configurations.
NOTE4: 10 users per TRxP is the baseline with full buffer traffic. 20 users per TRxP with full buffer traffic is not
precluded.

6.1.5 High speed
The high speed deployment scenario focuses on continuous coverage along track in high speed trains. The key
characteristics of this scenario are consistent passenger user experience and critical train communication reliability with
very high mobility. In this deployment scenario, dedicated linear deployment along railway line and the deployments
including SFN scenarios captured in Section 6.2 of 3GPP TR 36.878 [6] are considered, and passenger UEs are located
in train carriages. For the passenger UEs, if the antenna of relay node for eNB-to-Relay is located at top of one carriage
of the train, the antenna of relay node for Relay-to-UE could be distributed to all carriages.
Some of its attributes are listed in Table 6.1.5-1.
