As 3GPP RAN1 and RAN4 delegate submitted multiple TDocs and CRs during Re. 8 to Re. 12 LTE standardization.
Generated multiple patents and publications by working with international cross functional teams.
Developed network and system level simulator (BWSim) to support RAN study and work items.
Submitted multiple Spec CRs on small cells and FeICIC during 3GPP Re. 12.
Implemented end to end base band DL physical layer transceiver modules.
Heterogeneous Networks with Macro, Pico, and Femto Cells : Cellular Network simulator with MeNB deployment is enhanced to accommodate PeNB and HeNBs. Features like PeNB deployment, Pico biased association, subframe blanking as per FeICIC framework are developed.
Receiver abstraction mode based on MMIB criterion is developed to abstract system level simulations.
Worked on ON/OFF, Load balancing, load shifting schemes for super dense clustered smallcells.
Developed a Cellular network level simulator called BWSim in CEWiT with following features :
o Hexagonal multi-cell model with distance based path-loss and shadowing modeled.
o Throughput, BLER, and Spectral Efficiency CDFs are generated for LTE DL Transmission modes 1 to 9.
o AWGN and Fading channel models are supported with low, med, and high correlation.
o DL MIMO-OFDMA end to end baseband system with proportional fair, round-robin MAC schedulers.
o Link Adaptation, Turbo encoder, codeword to layer mapping, precoding, antenna mapping.
o CQI/PMI/RI reporting, Channel estimation, MMSE/MRC/ZF detection, demodulation, Turbo decoder, LLR generation.
