3GPP 5G Status
RAN chair views on 5G and IMT-2020
– “5G” is a marketing term that companies will use as they see fit.
• 3GPP will not try to answer the question “what is 5G?”
• Moving forward 3GPP will no longer use the term “5G”, especially in
official documents such as TR, specs
– “5G” will include work on a new radio
• The actual scope & requirements of the new radio will be defined when
the work starts in RAN
• A base name should be selected for the new radio. Proposal to create a
task force to select the new name
– IMT 2020 will be defined by:
A.
The requirements set by ITU-R for IMT 2020
B.
What 3GPP will decide to submit to ITU-R in terms of IMT 2020
technology proposal (based on the requirements established in A.)

Preliminary Conclusions (2)
– Likely two phases for the normative work
• Phase 1 to H2 2018 - Phase 2 to Dec 2019
– Initially specify support for a subset of the identified use cases &
requirements
• Design of the new radio should be forward compatible
– Some form of prioritization for phase 1
• Lack of consensus - Should be resolved by March 2016

Initial RAN4 NB-IoT Discussions
– The first real debates on NB-LTE and NB-CIoT started at RAN4 in
October
– The long-standing GERAN proposal was unexpectedly challenged
at the September plenary by the NB-LTE proposal and this has set
up a big confrontation between the stakeholders
– The big technical issue is over the co-existence of the GSM-based
NB-CIoT for the cases of deployment near or inside LTE spectrum
– For NB-LTE there are no co-existence issues but not so with GSM
– RAN4 cannot agree if RAN1 or RAN4 should perform the analysis
as this is an intra-operator issue which is a bit different to the usual
RAN4 inter-operator co-existence studies

Dual Connectivity in R12

LWA in R13
Building the Background to Dual Connectivity
Co-located CA in R10
– The original goal of CA in Release 10 was to
increase the spectrum and hence peak
data rate available from one cell site
Two carriers in the same band
with very similar coverage area
Two carriers of different frequencies
showing different coverage areas
But when the 2nd carrier is
at a very different frequency,
the benefit of CA is limited to the
centre of the cell which is not ideal
3GPP Release 12,
13 & 14 Update

Page 35
Building the Background to Dual Connectivity:
Inter-site CA
– By allowing CA between sites it is possible to provide
continuous CA coverage using a low frequency macro
(umbrella) cell and local capacity using a higher
frequency
Macro umbrella cell
Inter-site CA still assumes
ideal backhaul for low
latency MAC layer crosscarrier scheduling
Small

Small

The separation of the sites means
that enhancements are required at the

Page 36
Dual Connectivity
Release 12 - CA between sites with non-ideal backhaul
– The ultimate flexibility is then achieved if CA is performed across
sites and radio access technologies (RATs) and in particular with
femtocells or WLAN, which may not have ideal backhaul
Macro umbrella cell
Small
cell
With non-ideal backhaul, MAC level
cross-carrier scheduling is not possible
so less tightly coupled solutions at higher
layers are used. CA with WLAN also forces
service-level integration e.g. Hotspot 2.0.

Femto
But dual connectivity CA
between LTE and Wi-Fi
may not be essential

Study and Core on Licensed-Assisted Access
Using LTE (LAA) in R13
– Following considerable recent interest at 3GPP in the operation of LTE in unlicensed bands a
new study item has been opened.
– The unmodified use of LTE in the ISM band has been called LTE-U. It is the most controversial
due to the expected interference issues.
– The purpose of LAA is to modify LTE to better enable operators to offload traffic to LTE
femtocells without having to implement WLAN
– The initial focus is on the 5 GHz ISM band used for WLAN
– Proposals are controversial since standard LTE interferes with WLAN
– LTE is shown to be more efficient - but WLAN was there first
– Modifications to the LTE air interface will be proposed to make co-existence with WLAN more
tolerable (e.g. Listen Before Talk – LBT)
– US regulations do not require LBT but Europe and Asia do
– LAA is likely to become the single biggest increase of cellular spectrum (up to 680 MHz in 5
GHz band) since the allocations given at WRC 07 Then there is 60 GHz…

LAA Deployment Scenarios
(RWS-140029)
– Initial results show that, when augmented with the appropriate
coexistence mechanisms to operate in unlicensed spectrum, e.g.
Listen-Before-Talk, LTE can effectively coexist with WiFi and
outperform it in terms of spectral efficiency

LAA Deployment Scenarios
(RWS-140029)
– Strong interest to start first with Licensed-Assisted Carrier Aggregation
operation leveraging on the existing LTE Carrier Aggregation framework
• Two available options:
(1) Cells on unlicensed spectrum used for downlink only
(2) Cells on unlicensed spectrum used for both downlink and uplink
• Many companies propose to start working on (1) then follow with (2)
– Most of the companies see the value to study Licensed-Assisted Dual
Connectivity operation as well, but prefer to do so at later time
• The feature will hopefully leverage on the Dual Connectivity feature currently
being developed in Rel-12
– Diverging opinions on Standalone operation
• Some companies proposed to study also this mode; some companies
explicitly requested not to study it.

3GPP Industry LAA Workshop
– This was an entertaining clash of different standards cultures
– IEEE/WI-FI Alliance don’t trust 3GPP to do the right thing to
safeguard existing 5.8 GHz ISM band users
