5GIC approach
Monday, 17 November 2014 [email protected] #5GIC
Starts from end user QoE (H2H, H2D, D2D)Unlike 2G….4G , designed for end device
Capacity & Energy efficiencies, Latency , ReliabilitySpeed is not the differentiator between 5G and previous generations
Latency e2e and radio access
Spectrum and system agnosticNo difference between licenced and licenced-exempt bandsBroadcast, Cellular, WiFi technologies(Data, Video, Audio)
5G should start with high density cells macro cells1G….4G started with macrocells small cells
New Air-Interface?
Monday, 17 November 2014 [email protected] #5GIC
Ultra Dense Cells Scalable to
Medium and low density cells
From narrow band to broadband services
New Air-Interface and New KPIs
Monday, 17 November 2014 [email protected] #5GIC
Objectives ‐NOT link spectral efficiency
Low control signalling overhead for management,
No stringent time‐frequency control as in OFDMA
Light MAC protocol
Support fast and reliable spectrum sensing for opportunistic spectrum sharing with and without database support
Highly energy efficient
Flexible implementation of carrier aggregation across highly fragmented spectrum including license‐exempt band
Allow full‐duplex operation
Sub‐millisecond Air‐Interface latency
Scalable for device to device and machine type communications
Will 5G provide Higher Speed ?
Monday, 17 November 2014 [email protected] #5GIC
Main reasons
Low latency: Full utilisation of advanced techniques potentials
QoE: Fast network responses
