5G Key Technologies/Trends

Advanced MIMO and Beamforming New numerology, protocols and access schemes for IoT Inter-RAT tight interworking Flexible 5G RAT air interface D2D/Underlay networks Network transformation and extension to edge and devices

Advanced MIMO/beamforming

Beam aggregation to increase cell-edge data rate Adaptive 3D beamforming towards target users

Multi-site coordinated transmission enabling cell-less network architecture

• Transmit and receive beamforming
• peration 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 interworking

Tight 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

5G IoT

Massive 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

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 Cloud Basic 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
