* MAC (Medium Access Control)
* RLC (Radio Link Control)
* PDCP (Packet Data Convergence Protocol)
* Support development of UE and base station (gNB) emulation solutions
* Analyze and implement features from 3GPP LTE and 5G NR specifications
* Assist in translating requirements into:
* Clean and maintainable code
* Test cases and validation scenarios
* Collaborate with cross-functional teams (systems, RF, protocol, software) to:
* Investigate and debug protocol behavior
* Support issue analysis and resolution
* Participate in continuous learning of evolving standards and technologies (5G Advanced, pre-6G)
Required Qualifications
