• MODEM System Test lead responsible for 5G NSA and SA Sub-6/mm-Wave features validation. • developing test strategies, lab plans & System Design reviews for upcoming features for UE • Validation 5G NR Physical and MAC layer features like Beam Management (Beam Selection, Refinement, Switching, Recovery), PUCCH and PUSCH frequency hopping, TDD K0/K1/K2, semi static and Dynamic HARQ Codebooks, Periodic and Aperiodic CSI, 4CC CSI, Power Control, Leg switching NR and LTE, SR, C-DRX, 4CC and 8CC throughput performance • Building test scripts with KeySight UXM PRT for scenario failed in the failed trail. • Execution and support for LTE ,5G (NSA and SA) IOT certifications. • Analyzing the logs of LTE and 5G MODEM Issues focused at RRC, Layer2 ( RLC, PDCP, MAC) . • Involve in Carrier (AT&T,TMO) and PTCRB certification for the Smartphones, Modem ,chipset. •Validating of radio functionalities like measurement gaps, CSI reporting, paging, C-DRX, BSR, SR, PHR validation, power control (PUSCH, PUCCH), SRS

The project deals with validation of Stock/Non Stock Devices on the Carrier validated scripts using different Network simulators like Anite 9000/R&S/Spirent/Anritsu. Scripts involve testing on different Protocol Scenarios for interoperability testing for North America operators like AT&T and TMO.I was responsible to lead the team and guide the complete testing process for the certification of devices for different NA operators. Analyzing the failure on the customer devices and sharing the analysis with the Dev team for the closure of the issue.

This projects was aimed to get AT&T certification for the module/smartphone devices to be launched in North America Operators such as AT&T/T mobile
