3GPP Standardization Status
Candidate Technologies for B4G and Beyond
• Device to Device (D2D) Communication
• Full Dimension MIMO (FD ‐ MIMO)
• CoMP with Non ‐ Ideal Backhaul
• Network Assisted interference Cancelation and Suppression (NAICS)
• Millimeter Wave (mmWave) Communication
Concluding Remarks
17. 17
Delay ▶ Long discovering time for service discovery
Scalability ▶ The number of connected devices is limited.
Range ▶ Small range (less than 100 meter)
Power
Consumption
▶ Asynchronous carrier sensing protocol
Interference ▶ Low reliability of the radio link
Limitation of Wifi‐directWifi‐Direct vs. D2D ProSe

Inter‐eNB CoMP with Non‐Ideal Backhaul
Release 11 CoMP Release 12 CoMP‐NIB
• Focuses on air‐interface aspect only
Relies on proprietary interface between
eNBs
Not designed for robust performance in
networks with non‐ideal backhaul
• Should support network interface for
inter‐eNB coordination
Support coordination among eNBs of
different vendors
Design to provide robust performance
even in networks with non‐ideal backhaul
