Integrated functionality of some of the key features listed below on SUB-6 (QC fsm100xx), FlexRAN and FR2- Millimeter Wave (MMW) platforms

RU

• Split-6 Integration as a part of Denseair DCMS project along with Radisys
• NFAPI integration

DU

• PUCCH CLPC: TPC evaluation is done by statistical analysis (using Python script) of ULSNR values received

Integration was supported plotting Pathloss vs PUCCH TX PWR

• DCI 0_1 along with UL DMRS enhancements: CDM group marking in RE is evaluated on Sanjole tool
• New BWP addition: This feature was Integrated to support different UE vendors to connect to Airspan GNB
• Multi-Carrier support on Dual cell platforms
• UL Centric and Semi Synchronous frame structure: Validated for Japanese Customer
• Other SIB’s Integration (OSI)
• Extensive MAC-Phy analysis with fsm 100xx

CU

• 5G QoS: Validated CU Algorithms for 5G QoS implementation for GBR and Non GBR DRB’s
• UE Context Modification Required (UCMR)
• PDU Modification on GBR and Non-GBR DRB’s
• A5 Events with different HO types (Inter Freq. Xn/Ng HO validation)

Python Framework

• DCI Decoder
• Command Line Plugins to trigger UCMR
• IQ Plots for fronthaul analysis

Apart from this I was actively involved in Debugging Customer issues, new POC’s, KPI Monitoring, Feature Sanity Tests.

• PW-EMS: REST API based framework to manage All RAN nodes
• Integrated 4G features: DRX, TTI Bundling.

• Built Team of engineers with different background to handle IoT for Rakuten
• Active Participation in Test Planning, Task allocation
• LTE Small Cell With integrated relay backhaul for customer SPRINT

Some of the key features covered under QA on smalls and macro cells platform are:

• 4G ETWS/CMAS: Write Replace Warning Request (WRWR) triggered using Amarisoft core.Feature has been extensively validated with different message size, SIB periodicities etc. Testing was successfully completed on RJIO and AT&T field
• DRX Validation with Altiostar vCU
• Advanced QCI Validation: This feature has been validated for QCI 65, 66, 69 and 128. Majorly validated for MCPTT
• Altiostar vCU API Integration.

• ERICSSON ENIQ Events Performance Management
• Designed Automation framework for KPI management
• RRM Handling for LTE: Bearer Control Algorithm implementation in C++ on Linux platform
• Integrated RRM module with open-source LENA NS-3 Network Simulator
• Strong experience in handling Aeroflex 7100 Base station Emulator
• Customer Demos.
