TSDSI 5Gi standard merged with 3GPP 5G


New Delhi, 29 April 2022

TSDSI’s 5Gi standard has been formally merged with the 3GPP 5G Standard and implemented into the 3GPP Rel-17 NR specifications in the just concluded RAN#95e meeting.

3GPP RAN approved two Rel-17 Change Requests (CRs) that enables Pi/2-BPSK waveform with filtering to be implemented in the 5G Networks.  This indigenously developed technology enables the deployment of 5G cell sites with long range – an important requirement for improving cellular and IoT connectivity in rural India.

This is a culmination of efforts of proponents of LMLC (Low-Mobility-Large-Cell) and 5Gi from our membership – from academia, R&D, industry who worked tirelessly from 2016 onwards to make this happen. The sustained support from DoT in this journey is sincerely appreciated. TSDSI also thanks our partners and peer forums, from across the globe, whose support for LMLC and 5Gi RIT at ITU and 3GPP, made this possible.

Adoption of this technology in the 5G standards will enable India to leap forward in the 5G space, with key innovations introduced by Indian entities accepted as part of global wireless standards for the first time. The nation stands to gain enormously both in achieving the required 5G penetration in rural and urban areas as well as in nurturing the nascent Indian R&D ecosystem to make a global impact.
