Current Project Aricent LTE-eNodeB Protocol Stack Development ( Integration with
Broadcom eNB Board BCM61750) (Oct 2013 – t i l l date)
Posit ion/Role Senior Software Engineer
Description Aricent LTE-eNodeB framework integrates Layer 2 and Layer 3+ modules in a
package that serves as a robust reference platform on which to develop complete
LTE eNodeB solutions. It provides complete Layer2 and layer3 functionality, and
exposes clear interfaces for Telecom Equipment Manufacturers to incorporate
product differentiation in areas such as SON, RRM and OAM.
Responsibi l i t ies
/Task
Integration of eNodeB framework layer2, layer3 with Broadcom board (BCM61750)
as per board architecture and functionalities, Performance Enhancement and
maintenance for support case and internal issues.
• Design and Integration of eNodeB framework using C on Broadcom board
(RT-Linux platform) which included:
o Implementing mailbox communication between processes running
on different CPUs.
o Communication of layer2 and layer1 FAPI messages.
o Defining and parsing XML file for declaration and definition
configuration information
o Fast Socket implementation for user plane data received/send
between EPC and eNodeB.
• Execution of Test cases for both FDD and TDD releases.
o UE Measurements &Mobility– It involves configuring measurements
at the UE and acting on the Measurement reports received.
o Admission Control – Admission of new UE or a Hand-in UE,
Admission of more RABs of the existing UE.
o Resource Allocations – Allocating CQI (Channel Quality Indicator) &
SR (Scheduling Requests) resources to the UE.
o Power Control& Transmission Mode Switching – Tuning the UE
specific power control parameters like p0-ue-pucch, p0-ue-pusch
and switching the transmission mode based on the radio conditions
experienced by the UE.
• Troubleshooting issues reported by testing team using tools like GDB
• Supporting enhancement, wrote the plan and procedures for the same and
performed Unit testing.
• Coordinated with customer for Performance Test activities.
• Currently working at client site (contela, sunae - south korea) as onsite
Engineer.
