TSDSI’s Initial Proposal on candidate RIT/SRIT for IMT 2020 Accepted


TSDSI’s Initial Description Template for RIT/SRIT for IMT-2020 accepted in ITU-R SG5 WP 5D meeting in Cancun, Mexico

TSDSI is delighted to announce that our initial proposal on candidate Radio Interface technology (RIT/SRIT) for IMT 2020 technologies, related to improving coverage and spectral efficiency performance, has been accepted in the WP 5D meeting #30 held in Cancun Mexico. The proposal suggests improvement in the UL modulation based on pi/2 BPSK with spectral shaping for coverage extension in all 5G bands. Possible enhancement to advanced antenna system (through non-linear precoding), control signalling, mobility management, relay/repeaters and UL pilot for coverage improvements have also been indicated. The proposal further adds one missing band viz., n40 (2.3GHz) which is already available in India as an LTE band.

This is the first time that an Indian SDO is proposing a possible candidate solution in response to the requirements from ITU-R. TSDSI had earlier indicated its intention to submit its candidate RIT/SRIT technology for IMT-2020 at the ITU-R WP 5D meeting #29 held in Seoul and informed that it will be based on 3GPP release 15 and onwards which may include enhancements based on Indian requirements and technologies.

The technical activities related to RIT/SRIT contribution are being championed by the Study group – Networks in TSDSI. TSDSI plans to make a full candidate IMT 2020 submission as per the ITU-R timelines to address India specific requirements. Deadline for final submission of the entire specification along with self-evaluation report in the required format is the ITU-R meeting #32 (July 2019).

I have been associated with the IT industry for ... well more than 35 years. I am fascinated about our hyper-connected world and how this hyper-connectivity is going to impact our civilization. Hence, I blog about it - whatever I see as an impact of hyper-connectivity, what I think may happen or may not happen.
