All Things Connected
• Scalable 5G air interface for cellular IoT (Internet of Things)
– Keep OFDM structure, multiplex different sub-systems together.
Coexist with LTE at low bands, easier for deployment.
Best use existing LTE spectrum to enable IoT applications

• Longer Symbol, Smaller Sub-carrier Spacing.
• Massive MTC connections
• Easier synchronization, deeper coverage (e.g. PSD boosting)
• Shorter Symbol, Larger Sub-carrier Spacing.
• Finer time granularity for latency reduction

All Things Connected
• New access scheme based on contention is promising– Less overhead, shorter latency suitable for bursty small packets
– Contention based access for latency and capacity (connection density) improvements
Avoid TA adjustment by longer symbol length (smaller sub-carrier)
