I have been working in 5G ML1 for about four years now on MSIM aspects of 5G, covering a wide range of topics in DSDA/DSDS flows.

Recent areas of work:

• 6Rx MSIM (software flow design/implementation, off-target/on-target validation)
• NRDC MSIM (implementation, off-target/on-target validation).
• DSDA flows implementation and verification.
• CDRX opt flows to save power in MSIM.

Areas of daily work:

• Scoping software changes required based on new requirements, covering multiple scenarios.
• Triaging stability and performance issues in MSIM, formulating solutions, and verifying fixes.
• Timeline analysis of MSIM flows and finding areas for improvement whenever needed.
• ML1 DL PoC for various modems, tracking daily change requests across the entire ML1 DL subsystem, and following up with INT and developers when facing any process-related issues.

• Dec 2017 - Dec 2020
• I have been working on the following areas: CFCM, Coex Manager, STMR, SLPC, WWAN Coex, and RTSAR.
• Key Projects: Software Engineer.
• 1) NR5G time conversions for scheduling multiple events, and time conversions for L1.
• A) APIs to schedule and service parts of the events.
• B) Came up with solutions to overcome the hardware limitations of the maximum possible time for the scheduler.
• C) Have a good understanding of NR5G frame structure and tech time to USTMR conversions.
• The NR5G and LTE coexistence feature mitigates the Tx power for several band combinations in SSIM (NSA) and MSIM (NR5G + LTE) modes of operation, along with new features based on this framework.
• 3) Came up with a design for accommodating the PMIC chip (76.8M) error during sleep, and sleep timing conversions.
• 4) SAFE-Sar fallback mechanism for Microsoft.
• 5) Power optimizations to open the UART only when required.
• 6) Multiple flow control modules for NR5G, LTE, and WLAN to monitor different temperature and bandwidth mitigations.
• 7) Converted static threads to a thread pool (dynamic allocation) for SLPC.
• 8) Handled multiple software feature bring-ups, hardware (UART) feature bring-ups effectively for the latest X55 chipsets.

• Worked as an LTE protocol verification engineer for 2DLCA, involving all connected mode test cases, including mobility, measurements, throughput, etc.
• Where multiple test cases were written to verify the LTE protocol stack, internal features.
• Have a good understanding of LTE call flows, ACK/NACK, frame structures, valid band combinations, FDD, and TDD frame configurations.
