Speed5G Workshop London presentation of the Speed5G workshop Demos

  1. 1. What demos are we showing and why www.speed-5g.eu Presenter: Andreas Georgakopoulos SPEED-5G Workshop Advanced Spectrum Management in 5G+ Networks London, 7th March 2018
  2. 2. Two Main Demonstrations 35 Demonstration 1 Combination of centralised and decentralized radio resource management with a novel MAC protocol for higher capacity in small cells Demonstration 2 Exploitation of heterogeneous spectrum resources through tight integration of multiple RATs at MAC layer
  3. 3. Demonstration 1 Key Points 4 Addressing the problem of spectrum and radio resource management in a 5G context 4 Environments with many small cells (up to the order of hundreds) 4 Scalability becomes an issue 36 A distributed approach is proposed
  4. 4. Demonstration 1 Overall Concept 37
  5. 5. Demonstration 1 Architecture 38 Backhaul cRRM EPC Access dRRM dRRM dRRM
  6. 6. 39 Traffic mechanisms Net. Service Management Small cells/ dRRM MAC cRRM (Macro) 3a. Invocation (e.g. notification request for approval ) 3b. Handling (e.g, Fine-tuning, Acceptance) 3c. Reply (e.g., Acceptance or alternative operation framework) 5. MAC interfacing 6. New operating framework 1. Anticipated situation (e.g. increased load) 2. Decision on bands to use (e.g. aggregate) • 0-Operator. Learns the radio environment; Operates in certain framework 5. MAC interfacing BackHaul 4a. Invocation (e.g. for BH optimization/calibration) 4b. BH optimization 4c. Reply (e.g., Acceptance or alternative operation framework) Demonstration 1 Sequence
  7. 7. 40 UE1 USRP-OAI (WINGS) BS1/dRRM USRP-OAI (WINGS) UE2 USRP-OAI (WINGS) BS2/dRRM USRP-OAI (WINGS) UE-MAC-FBMC FLEX BOARD (CEA) BS-MAC-FBMC FLEX BOARD (CEA) cRRM PC-SERVER (BT, WINGS, UNIS) Phase 1: Trigger (e.g., switch on second UE, increase traffic of UE1 and UE2) Phase 2: Decisions (distributed) Phase 3: Messages to/from cRRM Phase 0: Initial condition BH (ICOM) Phase 4b: Backhaul Optimization Demonstration 1 Phases Phase 0: Initial condition Phase 5: Messages to MAC/ configurations (bands to use) Phase 4a: Messages to backhaul
  8. 8. Demonstration 2 Key Points 4Traffic splitting 4Traffic offloading ➨ Different offloading ratios, which can be changed at the run time 41 Higher capacity through the aggregation of wireless technologies
  9. 9. Demonstration 2 Overall Concept 42
  10. 10. Demonstration 2 Architecture 43
  11. 11. Demonstration 2 Sequence 44 eNB UE UE Capability Enquiry/Information RRC Connection Reconfiguration/Complete (triggered by HMAC) Non-LTE RAT (e.g., WLAN) Measurement Report RRC Connection Reconfiguration/Complete (triggered by HMAC) Non-LTE RAT (e.g., WLAN) Connection establishment Start sending data traffic Adapt offloading ratio based on the link quality and RLC BSR for DL and split traffic accordingly Adapt offloading ratio based on the link quality and RLC BSR for UL and split traffic accordingly LWA
  12. 12. Conclusions 4 Two main demonstrations ➨ One focusing on HRRM (cRRM/dRRM) benefits ● The objective of this demonstration is to highlight how the SPEED-5G outcomes can be implemented to optimize the usage of spectrum resources and deliver the best QoS in dense heterogeneous networks by exploiting distributed radio resource management. ➨ One focusing on tight integration of multiple RATs at MAC layer ● The objective of this demonstration is to highlight project innovations related to inter-RAT, e.g. LTE and WiFi, resource aggregation and traffic steering/offload, based on a MAC-split solution. 45
