Communication Systems Department

EURECOM

Unleashing the potential of open-source in the 5G arena

Summary

Overview of EURECOM’s 5G test site

– Part of H2020 5G-EVE French Node (along with similar test sites

@ Orange Labs, B-COM, Nokia Bell-Labs)

– Part of OPFNV VCO 3.0

Strong Collaboration with RedHat on cloud computing

environment for RAN / CN

– field testing site for OAI CI/CD

Overview of EURECOM Test Site

EURECOM 5G Test Site

Outdoor deployment of 5G-NR RRUs (+LTE-M/NB-IoT)

Frequency allocations in place / pending – 3600-3680 MHz TDD (61 dBm EIRP, NR band 78) => 5G eMBB/URLLC

– 2580-2610 MHz TDD (61 dBm EIRP, LTE band 38) =>

– 698 – 703/753 – 758 MHz FDD (LTE band 68) => IoT / ProSe

– 733 – 736/788 – 791 MHz FDD (LTE band 14) => IoT / ProSe

Experimental Playground for OAI – Target scenarios : eMBB, URLLC, mMTC, D2D

Outdoor RRS (16 -> 64 elements)

Indoor RRS (32 elements)

Overview of EURECOM Test Site

Two configurations

1/ All Core + RAN entities at EURECOM

– Will use functional splits inside RAN/CN Cloud under OpenShift

– Each functional entity (MACRLC, L1, MME,HSS, etc.) in

separate containter

– Simple orchestrator

2/ Control-plane and User-plane split between site

– Control plane in another 5G-EVE site (e.g. Orange Chatillon)

MME,HSS,RRC,PDCP-C

– User-plan entities at EURECOM site

SDAP/PDCP-U, MACRLC, L1 at EURECOM site

– ONAP orchestration from Orange

Overview of EURECOM Test Site

Some objectives for OAI using the site

Integrate the site with OAI CI/CD framework

Collaborate with RedHat to make OAI + OpenShift

combination a tool for community

Master remotely-controllable UEs in the field

– Need agreement from local authorities and communities

Stationary and mobile CAT-M devices (Band 14/68)

access to nearby highway

Add cell site around Orange Labs premises in

Sophia Antipolis (3 km away)

Mutualize some techniques for operating such

networks with PAWR sites (Utah, NYC)
