O-DU High

Primary Goals: 

  • O-DU high integration in Radio mode
  • Initial access and Attach procedure testing in Radio mode
  • DL and UL data path in FDD, 20 MHZ with 256 QAM and 64 QAM respectively
  • Static TDD mode support with Numerology =1
  • O1 enhancement
  • Closed Loop Automation Use case support

D Feature Scope: 

. 1. Achieve UL and DL data flow using FDD mode on 20 MHz Bandwidth, Numerology = 0

 2.Support for static TDD mode with pattern “DDDDDDDSUU” on 100 MHz Bandwidth, Numerology = 1

  • Evolve scheduler to support UL and DL scheduling of signaling and data messages on single spectrum in TDD mode
  • Expand scheduler to support Frame structure according to numerology = 1
  • Updates to cell broadcast for TDD and numerology = 1

3.Development activity for Closed Loop Automation use-case

  • Support for cell stop and restart within O-DU High layers
  • Support for cell stop and restart towards O-DU Low
  • F1AP Enhancements towards O-CU indicating cell stop and restart

4.Integration

  • Integration with O-DU Low in Radio mode
  • Integration with CU

5.End to end testing support (O-RU<->O-DU-LOW<->O-DU-HIGH<->RSYS CU<->Viavi 5G Core )

6.O1 enhancements - by HCL

  • CM Support
  • Support for Closed Loop Automation use-case
  • Support for Health Check use-case
