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
