27. 5G New Radio “NR”
Efficient Multiplexing of Different Services with SC-OFDMA

28. 5G New Radio “NR”
IoT Key Features
Narrow BW
NOMA
Increased density & Capacity
Efficient uplink
Multi-hop Mesh
Device to Device, uplink data
relayed via nearby devices
Grant Free Access
No need for scheduling
Efficient signaling
Power efficient – longer battery life

29. 5G New Radio “NR”
Non-Orthogonal Multiple Access “NOMA” – Greater Efficiency

30. 5G New Radio “NR”
Non-Orthogonal Multiple Access “NOMA” – Example
Why NOMA is good for 5G?
The use of OMA gives the
sensor (low data rate) more
than it needs
The bandwidth allocated for
a user with very poor channel
conditions via OMA is not
used efficiently

31. 5G New Radio “NR”
In-Band Full Duplex – Simultaneous TX/RX, same Freq. Channel
