4G Architecture
E-UTRAN / eNodeB
■ Function for radio resource management radio bearer control, radio admission control, connection mobility
control, dynamic allocation of resource to UEs in both uplink and downlink.
■ Selection of an MME at UE attachment.
■ Routing of user plane data towards serving gateway.
■ Measurement & measurement reporting configuration for mobility & scheduling.

5G Architecture (Non-standalone)
Frequency Band and Subcarrier spacing
■ All Indonesian operators currently use
NSA (Non-standalone) which 5G network
is supported by existing LTE infrastructure,
so the control plane is still passed to 4G
eNB and EPC.
■ Network Slicing, URLLC and mMTC won’t
be supported in Non-standalone, but
improved broadband speeds will enable
services such as ultra HD 4K-8K video
streaming, augmented reality (AR)/virtual
reality (VR) and an immersive media
experience.

■ Standalone : NAS will indicate 5G Logo (similar to 4G)
■ Non-Standalone : SIB2 indicate 5G Logo, logo may appear even
when UE outside of NR coverage

Radio Optimization In Telco - Part 2

  • 3. 3 4G Architecture E-UTRAN / eNodeB ■ Function for radio resource management radio bearer control, radio admission control, connection mobility control, dynamic allocation of resource to UEs in both uplink and downlink. ■ Selection of an MME at UE attachment. ■ Routing of user plane data towards serving gateway. ■ Measurement & measurement reporting configuration for mobility & scheduling.
  • 4. 4 Telkomsel Indosat Ooredoo XL Axiata Frequency Band n40 (2300MHz) n3 (1800MHz) n3 (1800MHz) Bandwidth 30 MHz 20 MHz (DSS) 20 MHz (DSS) Numerology/ Subcarrier spacing 1/30kHz 0/15kHz 0/15kHz 5G Architecture (Non-standalone) Frequency Band and Subcarrier spacing ■ All Indonesian operators currently use NSA (Non-standalone) which 5G network is supported by existing LTE infrastructure, so the control plane is still passed to 4G eNB and EPC. ■ Network Slicing, URLLC and mMTC won’t be supported in Non-standalone, but improved broadband speeds will enable services such as ultra HD 4K-8K video streaming, augmented reality (AR)/virtual reality (VR) and an immersive media experience.
  • 5. 5 5G Key Technology Components
  • 7. 7 ■ Standalone : NAS will indicate 5G Logo (similar to 4G) ■ Non-Standalone : SIB2 indicate 5G Logo, logo may appear even when UE outside of NR coverage
