The decision to merge India’s 5Gi standard with 3GPP’s global 5G standard has received official approval. 5Gi is India’s own fifth generation standard. The decision was taken at the 3GPP TSG RAN plenary session.
3GPP is a global initiative that provides standards and specifications on telecommunications technologies. A plan of action was agreed at the 3GPP TSG RAN plenary (RAN#94-e), to allow the merger of 5Gi into 5G, with specific milestones set for both 3GPP and Telecommunications Standards Development Society, India (TSDSI).
Commenting on the merger, Wanshi Chen, TSG RAN Chair, said, “This merger will allow 3GPP to better support all markets with a single solution that will allow 5G to continue to evolve and prosper globally.”
In order to support low peak-to-average-power ratio (PAPR) transmissions, 3GPP has endorsed two Rel-17 change requests (CRs) clarifying the specification of the Pi/2- BPSK modulation scheme. In addition, the objectives of the RAN WG4-led Rel-17 work item along with a recent way forward for the same project have been amended.
In turn, TSDSI has committed to the merger of 5Gi into 3GPP along with a roadmap of pursuing merged 3GPP 5G specifications in India with no further 5Gi updates in ITU-R. The merger of the 5Gi standard into 3GPP, enables a single common specification going forward, as well as creating a single radio access proposal for the ‘IMT.2020’ 5G family of standards (ITU-R).
Once 3GPP receives communication regarding the completion of the pertinent actions by TSDSI, the CRs currently endorsed will be finally approved and implemented into the 3GPP Rel-17 NR specifications. This is expected to be achieved by the next TSG RAN Plenary (RAN#95e), likely by March or by June (RAN#96).
