    • O-RAN WG6 presentation ( Lucian) 

    • New Profile, is it new profile or re-active the Compute intensive "https://github.com/cntt-n/CNTT/issues/1569"  – Need to quantify how to handle the interface between the HW and the architecture.  Karim will get more information on the Certification programs.  as commented on the issue, the new edge profile should be technology-independent, we aim at several edge use-cases, and we can have FPGAs, GPUs,, etc. as accelerators... Can we make this Profile have a mandatory HW component, that is what makes it the distinguishing factor. Agreed that we DO need a new profile with a mandatory HW component. 

      • DU processes RLC, MAC and Hi-PHY layer. For Hi-PHY processing, FPGA accelerators are used for enhancing performance. If used, the FPGA is used for FEC offload at L1. For 5G NR, PHY is offloaded to the FPGA 

      • Real Time Signal Processing Task

      • Forward Error Correction (FEC) : Turbo/LDPC/Polar

      • Fronthaul Acceleration & Conversion

      • Telemetry ( latency )

    • RM Screening output 

      • CH02 : Analysis and Add profile 

      • CH03 : Nothing ( AZ ,..)

      • CH04 : https://github.com/cntt-n/CNTT/blob/master/doc/ref_model/chapters/chapter04.md#42421-network-acceleration-extensions 

      • CH05 : Need some work 

    • Start the Architecture (OS and K8s )

•  

  • CNTT Baraque  

    • Milestones 

      • May 29: M1 (Release Planning/Requirements)

      • Jun 19: M2 (Issue Logging)

      • Sep 14: M3 (Freeze contributions)  

    • Outlines and Roadmap items :

      • FPGA

      • Architecture 

  • Webinars:

    • Call for topics

    • CNTT Technical Webinar Topics

•  

  • Virtual Face-to-face  June 22-25 

    • Scot Steele is requesting topics for sessions, the deadline for 3rd of June 

    • This date is aligned with the LFN DDF

    • Topics requests should be added the June 2020 Virtual Conference - Topic Requests page

    • Topic brainstorming for Edge

      • Edge workstream: accelerator requirements, new profiles, etc 

  • liaison

    • Do we need it right now (Y/N) 

      • LF-Edge -akraino :

      • OpenStack - StarlingX :

      • GSMA - Telco Edge Cloud (led by Telefonica) second group led by Deutche Telecom :  - Should have someone from the GSMA groups to attend Virtual Face-to-face  June 22-25 to make sure we do not duplicate efforts!

      • TIP

      • O-RAN = WG 6

Minutes:

• Latency is the main issue, the why FPGA is mandated in Fronthaul ( 50-100 usec /tested) , in the mid-haul in msec

• List down all function that required for FPGA ( vRAN use case ) 

  • DU processes RLC, MAC and Hi-PHY layer. For Hi-PHY processing, FPGA accelerators are used for enhancing performance. If used, the FPGA is used for FEC offload at L1. For 5G NR, PHY is offloaded to the FPGA 

  • Real Time Signal Processing Task

  • Forward Error Correction (FEC) : Turbo/LDPC/Polar

  • Fronthaul Acceleration & Conversion

  • Telemetry ( latency ) 

• CNTT can have FPGA in the transition period without obligation toward the operator to use it

• AAL form O-RAN it will be a target to have a single abstraction layer for all acceleration tech.

•  for the new profile: the name "Edge profile" , covers many uses cases over the edge starting with vRAN

• For RA01 & RA02 , it will not new Arch, it will be tweaking of the normal arch to be fit at the edge and can be covered in subchapter/chapter in RA01&RA02
