Modified 5G standard developed in India, adopted by ITU

TSDSI has successfully introduced an indigenously developed 5G candidate standard, based on 3GPP Technology, at the International Telecommunications Union (ITU) in 2019 for IMT 2020 ratification. The TSDSI-RIT incorporates India specific technology enhancements that can enable longer coverage for meeting the LMLC requirements. The TSDSI-RIT, geared mainly to address the LMLC requirements, exploits a new transmit waveform that increases cell range developed by research institutions in India (IIT Hyderabad, CEWiT and IIT Madras) and supported by several Indian companies.

Historical milestones as narrated by Prof Kiran Kuchi,IITH:

 1. Meity funded CEWiT at IITM around 2005 (Bhaskar, Jhunjhunwala and Co.) I joined CEWIT in Jan 2008. Phase-1 of Indian crack at Standards Essential Patents (SEP) started with a 4G version of WiMax. Myself, Klutto and others at CEWIT developed first set of WiMax centric SEPs incorporated into IEEE 802.16m (4G version of WiMax) between 2008-11. WiMax did not take off and those efforts did not pay off at first.

2. 2011-2015 was a cool off period until TSDSI was born (Kumar first Chairman, Abhay Second and now Bhaskar 3rd Chairman of TSDSI). 5G NR standard development started at 3GPP 2016-18. Myself and Kultto made 30+ international trips  to push a waveform designed to have large coverage (now morphed into LMLC). It took 3-years to push this tech into 3GPP.

 3. 2018-20 LMLC (large cells + the waveform introduced by our team at 3GPP etc) concept introduced first at TSDSI SG1 then pushed through ITU by Prof. Ganti and team over 2-years, with support from TSDSI, DOT, IITs.

 4. Some 20 patents cover the essential aspects of this waveform that is now part of TSDSI ITU spec and also part of 3GPP rel-15,16/17.

 5. About 10-15 years from concept to standardization. Qualcomm and others have implemented this tech in 5G phones but Nokia and Ericsson had been adamant to include in the base station. I am sure with TSDSI spec approved at ITU. It will get into these networks as well. Another year to two before you see this on the field.

 6. I would like further add that Satish Jamadagni VP at Jio, vice chairman TSDSI, supported this effort by cosigning some 100 contributions at 3GPP, back channeling with MNCs several times. I must say that he convinced  Jio to  support this Indigenous effort. I worked very closely with him for about 4 years on this project...
