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)
