Access/backhaul integration

Spectrum flexibility

Device-to-device communication


› Wide range of spectrum regimes

– Licensed, licensed shared, and unlicensed

Spectrum Flexibility

› “Dynamic TDD”

– Adapt to instantaneous traffic variations

(especially in small-cell deployments)

Full duplex on link level… …or system level

› Possibility for full duplex

– Simultaneous Tx and Rx on same frequency

– Challenging interference-cancellation scenario


Ultra-Lean Design

Minimize always-on

transmissions (reference

signals, sync signals,

broadcast system info, …)

› Significantly reduced

energy consumption

› Interference minimization

means higher achievable

data rates and improved

capacity

› Future proof-ness


› Multi-layer connectivity

– Between overlaid low-frequency and

underlaid high-frequency layers

› Robustness

– Spotty coverage at higher frequency bands

› Multi-site transmission

– Reception of multiple beams

› Diversity and robustness

– Rapid changes in propagation

conditions makes connectivity to

multiple sites beneficial

Multi-Site Connectivity


› User-specific beamforming

– User-specific reference signals (DM-RS)

› A UE may receive multiple beams (from

different sites)

› Each beam is “self-contained” (minimize

dependencies across beams)

– Transparent support for SU-MIMO, MU-

MIMO, CoMP, dual connectivity
