Indoor Positioning Enhancement
• The Indoor Positioning study will first determine the performance of already specified
positioning methods in indoor environments and later evaluate potential improvements to
the existing methods, or new methods, in order to achieve improved positioning accuracy.
• While initially driven by the FCC request to improve the positioning accuracy in indoor
environments for emergency calls, the work can further expand the capability of the LTE
platform - allowing operators to address the growing market of indoor positioning.

ELIOT
Enhancing Location Capabilities for Indoor and Outdoor Emergency Communications
The topics covered includes, but not limited to developing or enhancing existing emergency
location service requirements arising from the Roadmap and the Fourth Report and Order:
1. Reporting vertical location requirements for emergency calls which may be based on
measurements of physical and environmental conditions (e.g. compensated barometric
pressure) or other positioning technologies
2. Supporting and delivering a dispatchable address (civic address with detail to
floor/room/suite number) of a mobile caller's location to the PSAP for emergency calls
3. Defining emergency location performance metrics including those based on physical
and environmental properties
4. Support technology alternatives demonstrating indoor location accuracy improvements
(e.g. A-GPS, TBS, multi-lateration)

Licensed-Assisted Access using LTE (1/2)
The goal is to study enhancements for LTE to operate in unlicensed spectrum.
While licensed spectrum remains operators’ top priority to deliver advanced
services and user experience, the opportunistic use of unlicensed spectrum is
becoming an important complement to meet the growing traffic demand.

Licensed-Assisted Access using LTE (2/2)
• An essential component of the study is to ensure coexistence between
LTE with WiFi and to provide a fair opportunity in accessing the
unlicensed spectrum.
• In terms of deployment scenarios, the focus will be on Licensed-Assisted
Aggregation (LAA) operation to aggregate a primary cell - using
licensed spectrum - to deliver critical information and guaranteed
Quality of Service, and a secondary cell - using unlicensed spectrum -
to opportunistically boost data rate.
• The secondary cell operating in unlicensed spectrum could be configured
either as downlink-only cell or contain both uplink and downlink.

Single-Cell Point-to-Multipoint (SC-PTM)
• For critical communications, radio efficiency should be seriously
considered, whether critical communications are deployed in
dedicated network or in shared network.
• Problems for critical communications over eMBMS could be solved
by the so called Single-cell Point To Multipoint (SC-PTM)
transmission, where:
– Multicast is performed over PDSCH on a per cell basis.
– Common Group-RNTI is assigned to
a group of users to schedule the traffic
via shared radio resources.
– UE performs the SC-PTM reception either
in idle mode or in connected mode.

LTE support for V2X service
• The vehicular communication in this study, referred to as Vehicle-to-
Everything (V2X), contains the following three different types:
– Vehicle-to-Vehicle (V2V) Communications
– Vehicle-to-Infrastructure (V2I) Communications
– Vehicle-to-Pedestrian (V2P) Communications
• Introduction of V2X applications (use cases)
– V2V use cases
• e.g. Forward car collision warning, …
– V2I use case
• e.g. advanced navigation/telematics, cloud services, …
– V2P use case
• e.g. Pedestrian protection (threat alert) from car collision, …

LTE enhancements for Machine-Type Communications
The key objective of the work is to define a new low complexity UE
category type that supports reduced bandwidth, reduced transmit
power, reduced support for downlink transmission modes, ultra-long
battery life via power consumption reduction techniques and extended
coverage operation.
• Reduced bandwidth: to specify 1.4 MHz operation at the terminal
within any LTE system bandwidth, allowing operators to multiplex
reduced bandwidth MTC devices and regular devices in their existing
LTE deployments.
• Extended coverage: to improve by 15dB the coverage of delay-tolerant
MTC devices, allowing operators to reach MTC devices in poor
coverage conditions e.g. meters located in basements.

Elevation Beamforming / Full-Dimension MIMO
• To enable elevation beamforming and high-order MIMO
systems. Beamforming and MIMO have been identified as key
technologies to address the future capacity demand.
• To study two-dimensional antenna arrays that can also
exploit the vertical dimension.
• The new study will look into high-order MIMO systems with
up to 64 antenna ports at the eNB, to become more relevant
with the use of higher frequencies in the future.

Enhanced Multiuser Transmissions and Network Assisted Interference Cancellation
Potential enhancements for downlink multiuser transmission using superposition coding:
• Identify and study possible enhancements of downlink multiuser transmission schemes
within one cell
• Investigate the potential gain of schemes enabling the simultaneous transmission of more
than one layer of data for more than one UE without time, frequency and spatial
separation (i.e. in the same beam over the same REs) over the existing Rel-12 techniques.
• Identify required standard changes needed to assist UE intra-cell interference
cancellation or suppression for the objectives listed above
21Source: RP-141895 & RP-141896 (MediaTek & Alcatel-Lucent)
• Considering realistic deployment scenarios, traffic model
and trade-offs between system-level gain, UE complexity,
signalling overhead as well as specification impact. The
study will consider UE and eNB feasibility for the possible
enhanced schemes, with realistic UE and eNB impairments,
channel estimation errors.

OAM support for Licensed Shared Access
• Identify how the solution and architecture as
defined in ETSI TS 103 235 based on the
requirements in ETSI TS 103 154 may provide a
global solution also supported by the 3GPP
Network Management architecture defined in 3GPP
TS 32.101.
• Analyse the LSA functionalities and the
information flow defined in ETSI RSS, TS 103 235,
and study the impacts on Itf-N.
• Analyse how to support static and semi-static
spectrum sharing scenarios and reference use case
as defined by ETSI RRS as described in sect. 3.4

Study on New Services and Markets Technology Enablers
The study aims
‒ to identify the market segments and verticals whose needs 3GPP should focus on meeting,
‒ to develop the use cases and requirements that the 3GPP eco-system would need to support in the future.
The focus of this work is on the use cases and requirements that cannot be met with EPS.
The work is likely to span a number of 3GPP releases.
The use cases and high-level requirements
can be sourced from existing work such as
4G Americas’ Recommendations on 5G Requirements and Solutions
Chinese IMT-2020 (5G) Promotion Association 5G white paper
ITU-R WP5Ds IMT Vision – Framework
The 5G Forum of Korea’s 5G White Paper
The NGMN 5G White Paper
The future development of IMT for 2020 and beyond
Develop several use cases covering various scenarios and identify the related high-
level potential requirements
Identify and group together use cases with common characteristics
Select a few use cases (or groups of use cases with common characteristics) for further
development
Start new individual building block study items for each use case or group of use
cases identified in the previous step to further develop the use cases and their
potential requirements, and capture desired system requirements and capabilities
that apply across the different verticals. This is essentially a horizontal view of the
potential requirements to complement the vertical use cases.
On completion of study items in the previous step , review and consolidate the
resulting potential requirements from all of them

Use Cases & Services
• Three emerging high level use cases for Next Generation
Radio Technology (also from IMT 2020 discussion):
1. Enhanced Mobile Broadband
2. Massive Machine Type Communications
3. Ultra-reliable and Low Latency Communications
• Wide agreement that the Next Generation Radio Technology
should be able to support a variety of new services
– Automotive, Health, Energy, Manufacturing …
– Some of these new services are being described by SA1 in the
SMARTER project

RWS150073 (RAN Chair)

New radio
• Emerging consensus that there will be a new, non-
backward compatible, radio as part of Next
Generation Radio Technology
– Strong LTE evolution continued in parallel
• The requirements and scope of the new radio will be
established by RAN in the SI starting in December
– WGs will then proceed with the evaluation of technology
solutions in the SI starting in March

Phasing
• Emerging consensus that there should be two phases for the
normative work
– Phase 1 to be completed by H2 2018 to address a more urgent subset of
the commercial needs (to be agreed)
– Phase 2 to be completed by Dec 2019 for the IMT 2020 submission and
to address all identified use cases & requirements
• The above implies the following, tentative, release timing
29

Interworking & System Architecture
• There seems to be a need to also rethink the System
Architecture for “5G”
– This will be debated under the new SI to be approved by SA
• The level of interworking of the new radio with the
legacy systems needs to be discussed more in detail –
different opinion & nuances seems to exist
– This discussion will be done in cooperation with SA group
(for this it may be also useful the joint workshop tentatively
planned for H2-16)

Radio Interface Technology (RIT) definition
• The current definition of RAT in 21.905 is
– Radio Access Technology: Type of technology used for radio access, for instance
E-UTRA, UTRA, GSM, CDMA2000 1xEV-DO (HRPD) or CDMA2000 1x
(1xRTT).
• In order to accommodate a wide range of use cases as described by the
NGMN white paper, 5G air interface technologies will allow for more
flexible operation and support a variety of communication purposes
– Radio Interface Technology (RIT): Type of technology used for radio
communication between two or more devices, without limitation to the functional
capability or the purpose of the communication. A RIT may be used to provide a
traditional access function, a backhaul function, a direct device-to-device (D2D)
function between peers, or multiple such functions. A RIT may also support a
variety of different communication modes (e.g., unicast, multicast, broadcast)
and/or topologies (e.g., point-to-point, star, tree, or mesh). 33

Time Delay Scenarios and Analysis
There are several cases for the E2E delay definition in the local communication
scenario (e.g. with ultra-low latency requirement) as shown in Figure x1. Note
that the numbers in the figure indicate the component links of a communication
path, for example, 1 refers to the link from a UE to an eNB.

b) via ) 1,2, 3’, 4’,13,14 (in

Server (Client-Server). In
this case but the APP Server
is far away from EPC1.
The E2E time delay will be longer if we consider the process delay in each nodes.

Physical Limit for E2E Time Delay
The propagation delay is limited by physics,
i.e. the speed of light (299 792 458 meters per
second) in air and 2/3 of the speed of light in
fibre connection. With these limits, 1ms one
way transmission latency can be mapped to
300 km air propagation or 200 km for fiber
based transmission as shown in left Figure.
36
A.3 Conclusions
1. Local Communication:
 E2E time delay can not be less than 1ms.
2. Remote Communication:
 E2E time delay can not be less than 10ms. Source: 3GPP TR 22.891 v.1.0.0
