• Transmit and receive beamforming operation for both control and data channels

• Combination of analog and digital beamforming at both access point and user terminal

Lower frequency bands

Higher frequency bands

Inter-RAT tight interworkingTight coupling of LTE and 5G RAT to ensure smooth deployment migration, efficient traffic offloading over opportunistic radio links and seamless mobility across 5G small cells▪ LTE serves as fallback link when 5G RAT experiences blockage (for high frequencies)

▪ Control plane anchored at coverage layer

▪ Different levels of user plane coupling envisioned:

Intra-RAT and inter-RAT fast and robust mobility handling and RLF recovery is essential especially in higher frequency spectrum

Utilization of D2D connections for relay, local traffic offloading and aggregation to improve coverage, energy efficiency, robustness

Network densification with self-backhauling to extend coverage for high data rates, improve capacity, and reduce channel blockage

Enhanced D2D transmission with MIMO-BF at higher frequency bands to improve spatial reuse and spectral efficiency

Intel Confidential – Do Not Forward

5G IoTMassive IoT▪ 106-107 connections per km2, 10 years+ battery life▪ Small subcarrier spacing and long TTI▪ Non-orthogonal multiplexing to support ultra-high number of

connections▪ Lightweight and connectionless protocols to reduce signaling

overhead

Mission critical IoT▪ Packet loss ~10-9, end-to-end latency ~1 ms▪ Large subcarrier spacing and short TTI ▪ Exploiting frequency diversity/robust coding schemes to

improve reliability▪ Low latency uplink access and transmission (contention or

carrier sensing based shared data channel)

Remote CloudBasic Terminal

Sensing/Proximity Services

• To meet the content distribution and processing requirements, the cloud is moved to the edge

• A powerful device can also become a networking node itself to meet especially requirements for IoT

5G is about communications + computing and involves both network nodes and devices
