Biography
Barış Göktepe received his B.Sc. and his M.Sc. degree in Electrical Engineering from Berlin University of Technology (TUB), Berlin, Germany, in 2014 and 2017, respectively. Since 2013, he has been with the Fraunhofer Heinrich Hertz Institute (HHI) and joined the Multimedia Communications Group in the Video Coding and Analytics Department in 2015.
His research interests lie in channel coding, information theory and feedback in wireless communication and he authored more than 10 peer-reviewed journal and conference papers in the area of next-generation mobile communication. Currently, he is actively participating and contributing to the 3GPP RAN1 5G standardization in the fields of HARQ feedback, NR for Unlicensed, and URLLC.
Main Research Topics
5G Predictive HARQ
HARQ is a physical layer mechanism provides retransmissions based on the feedback to increase robustness. Predicitve HARQ focuses on providing the HARQ feedback earlier by predicting the decoding outcome, designated as Early HARQ (E-HARQ).
