  2. AGEN GENDA • What has happened so far • What is the way forward

  3. DISTRIBUTION OF THE DISTANCE BETWEEN VILLAGES AND THEIR CLOSEST GRAM PANCHAYAT The GP and village list was obtained from the government website http://lgdirectory.gov.in/. ISD : Inter Site Distance, R: Radius

  4. ITU-R Test Configuration: LOW MOBILITY LARGE CELL (LMLC) proposal for Rural Broadband proposed in Oct 2016 BS at the GP should serve the nearby villages Gram Panchayat Village Village Village Village Village Village Village

  5. IMT2020 Usage Scenarios (M.2083) – LMLC is mandatory June 2017 URLLC eMBB mMTC Test Environments Urban macro Urban macro Rural eMBB Dense Urban eMBB Indoor Hotspot eMBB URLLC mMTC Config A Config A Config A Config A Config A 4 GHz ISD 500m 700 MHz, 120/500 km/h 4 GHz 4 GHz (1 layer) Config B Config B ISD 1.732km Config B Config B 700 MHz ISD 1.732 km 30 GHz Config B 30 GHz (1 layer) Config C 4 GHz, 120/500 km/h Config C 70 GHz ISD 1.732km 4/30 GHz (2 layer) TPR are defined for the Test LMLC Environments 700 MHz, 30 km/h Test Configurations ISD 6km In addition, for Rural-eMBB test environment, average spectral efficiency value should meet the threshold values for LMLC evaluation configuration with ISD of 6000m and either evaluation configuration with ISD of 1732m

  6. IMT 2020 – RIT proposal Highlights of some of the Major Changes ITU-R WP5D #31 (Feb 2019) • Interim submission at ITU 1. Pi/2 BPSK with spectrum shaping and non-precoded DMRS. 2. Intelligent BWP configurations for resource block group (RBG) based scheduling. ITU-R WP5D #32,33 (July, Dec 19) • RIT submission at ITU – STEP 3 3. Low latency sounding reference signal (SRS) precoder update. 4. Intelligent PTRS threshold parameters. ITU Meeting #34 - #37 (Feb, June, Oct, Nov, Dec 20) • Step 4 to 8 (Evaluation & Harmonisation) • Final Approval at ITU DOT/TEC deliberations for making it a national standard

  8. TSDSI Proposal for 3GPP Release 17 • Capacity & Coverage enhancements(wrt Rel16) • In-Band Full-Duplex Study Proposal • IAB enhancement • MBMS support for 5G NR • Support for SA Deployment Option-6 • Consider DU&RU split options 3,6&7 • : TSDSI entrusted with the role to “ track in a horizontal umbrella fashion the progress made on sub topics, within the different Work Areas (for 3GPP Release 17), that are important for NR deployment in developing countries and report status to TSG RAN” 11
