We are looking for a 5G Cloud RAN Developer to join the existing Cloud RAN DU Baseband function development. Your role will include development activities such as : 3gpp spec implementation, algorithm design and implementation, test design, requirement analysis, tools design, system design, and product documentation.

What you will do :

• Implement NR Scheduler function and 3GPP Standards related to RRM, MAC, RLC, PDCP
• Contribute to development of RRM functions such as beamforming, massive MIMO, carrier aggregation, dynamic spectrum sharing, scheduling, link adaptation, power optimization in L2 scheduler
• Full-stack virtualization of the 5G NR DU on COTS HW
• Develop embedded real time software development running in cloud-based infrastructure
• Systemization, implementation and testing of 5G Cloud RAN Baseband features related to L2 scheduler in CR DevOps
• Troubleshooting BB scheduler and L2 stack
• Contribute to the architectural evolution of the BB L2 Scheduler SW
• Design new algorithms for baseband features, systemize the solution, implement in the product, and help with testing the solution in the lab, over the air, and in operator’s network
• Other areas that you may contribute to :
• Realization of machine learning base solutions in Ericsson Cloud RAN products
• Work with Kubernetes pods and docker containers on the far edge
• Define requirements, lab setup, and test cases; analyze and characterize the result and customer trouble reports.
• Work on open interfaces (e.g F1, X2 / Xn, A1, 01, LLS )
