3. WHAT IS 5G???
 Fifth-generation wireless (5G) is the latest
iteration of cellular technology, engineered to
greatly increase the speed and responsiveness of
wireless networks.
 5G will enable a sharp increase in the amount of
data transmitted over wireless systems due to
more available bandwidth and advanced antenna
technology.

4. 5G PROVIDES…
According to IMT (International Mobile
Telecommunications)
5G technology can provide:
1.Peak Data Rate: max rate per user under ideal
conditions i.e, 10 Gbps for mobiles.
2.User experienced Data Rate: Rate across the
coverage area per user i.e., 100 Mbps in
urban/suburban areas.
3.Latency: latency of 1 ms or lower for uses that
require real-time feedback.
4.Mobility: Max speed at which seamless handover
and QoS is guaranteed for Users.
5.Connection Density: Million Devices per square
kilometer.

5. 5G IN DIFFERENT SECTORS
 smart phone users are increasing, so the demand
for data will continue to grow as the number of
devices connected to the internet grows.
 Industries and consumers will rely on 5G networks
that can provide constant connections, minimal lag
times, increased bandwidth to access and share
data, and the ability to quickly compile and compute
data.
 In the health care sector, 5G could enable services
such as remote patient monitoring, consultation, and
even remote surgery.
 In transportation, 5G will be the backbone that
autonomous vehicles rely on.

6. 1G-5G

7. REQUIREMENTS FOR 5G
 According to IMT for 2020 and beyond ,5G technology requires three
main scenarios, such as
 enhanced mobile broadband (eMBB),
 massive machine type communication (mMTC),
 Ultra reliable and low-latency communication (URLLC).
 The main challenging requirements of eMBB scenario are 100 Mbps
user perceived data rate and more than 3 times spectrum efficiency
improvement over the former LTE.
 The main challenge of mMTC is to provide connection density of 1
million devices per square kilometer as a large number of IoT devices
will have access to the network.
 In case of URLLC, the main requirements include 0.5 ms end-to-end
latency and reliability above 99.9%

8. INTRODUCTION TO NOMA:
 Non-orthogonal Multiple Access (NOMA) is an
emerging technology for the fifth generation (5G)
wireless networks which can address requirements of
5G.
 The key idea behind NOMA is to serve multiple users
with power multiplexing.
 NOMA brings a step change in data speed and a
significant reduction in end-to-end latency.

9. WHY NOMA?
 Orthogonal multiple access has been used during
the past (1G-4G) as follows:
FDMA/TDMA/CDMA/OFDMA
 To realize a better trade-off between system
throughput and user fairness a promising solution
is to break orthogonality.
 NOMA serves more than one user on the same
time and frequency resource.

10. ADVANTAGES
 Noma offers higher spectral efficiency due to use of
multiple users on same frequency resource.
 It Provides massive connectivity by serving more uses
simultaneously at the same time.
 It Provides lower latency due to simultaneous
transmission all the time rather than dedicated
scheduled time slot.
 It offers better QoS to all the users using flexible
power control algorithms. It helps in increasing cell-
edge throughput and better user experience at cell-
edges.
 The NOMA along with MIMO delivers enhanced
performance.

11. LIMITATIONS
 If error occurs in single user, decoding of all the
other users information will be erroneous. This
limits maximum number of users to be served by
each of the clusters of the cell.
 Each users required to provide channel gain
information back to Base Station as feedback
and hence NOMA is sensitive enough to obtain
these measurements.

12. APPLICATIONS:
 The NOMA is beneficial for heterogeneous networks,
as more users can be served in a small cell by
exploiting the NOMA principle.
 The applications of NOMA to machine-to-machine
(M2M) communications, ultra-dense networks
(UDN), and massive machine type communications
(mMTC) are being studied, respectively, where the
use of NOMA can effectively support massive
connectivity and the IoT functionality of 5G.
