DoT-TSDSI Micro Workshop Series on ‘Advancing 5G towards 6G’ #Workshop 4: Studies related to ‘Physical Layer Technologies’ (February 17,2023 Online)

February 17 @ 11:00 am - 12:45 pm


DoT-TSDSI joint workshop series on ‘Advancing 5G towards 6G’ aims to disseminate information about 3GPP Release 19 technology areas and timelines to the Indian technology ecosystem. The goal is to mobilize Indian Industry technologists and Academic researchers to actively participate and contribute to the ongoing and future work at 3GPP.

The fourth micro-workshop in the series, conducted in partnership with IIT Kanpur, focused on the 3GPP Studies related to ‘Physical Layer Technologies’.

About this micro workshop:

The workshop introduced the audience to the latest physical layer technologies from RAN1 (physical layer) perspective which have the potential to be a part of 3GPP Release-19 and beyond releases towards 6G. The following topics were discussed in this workshop:

Intelligent Reflective Surfaces (IRS) – Intelligent Reflective Surfaces (IRS) provide an energy-efficient and cost-effective technology to realize smart radio environments. The potential performance gains by integrating IRS in future releases of 5G and beyond were highlighted. Implementation aspects and the related challenges were also highlighted.

Network architecture: from cellular to cell-free – 5G networks use cellular network architecture where users connect to a particular base station. Cellular architecture suffers from cell-edge problem wherein users at the cell-edge observe low data rates due to multi-cell interference. This talk aimed to introduce cell-free architecture which overcomes the cell-edge related limitations of cellular architecture and is shown to provide uniform quality of service to all the users in the network.

Evolution of smart network nodes – Network nodes such as Relays, integrated access and backhaul, and network-controlled repeater (NCR) have been a part of LTE and NR for improving the coverage of the cellular network. This talk described how intelligent reflective surface (IRS) can be incorporated in 5G networks for Release 19 and beyond. We also discuss the enhancements on Release-18 NCR as a potential item for Release-19.

Evolution of Positioning framework – Positioning is constantly evolving with every generation to meet the market demands. This talk discussed enhancements on positioning in terms of accuracy and power consumption for SideLink (device-device), and reduced capability (RedCap) devices, which are potential work items for Release 19.

New Waveform design – This talk focused on requirements of new waveforms and investigates the potential candidate waveforms based on performance in different frequency bands and various deployment use cases e.g., terrestrial mobile, NTN, Integrated-Sensing and high-speed scenarios.

Study on AI/ML assisted PHY layer communication – This talk first provided a brief overview of how AI/ML is being used to design NR Air Interface in Rel-18. It was then discussed how AI/ML can be used for incorporating integrated sensing and communications (ISAC) and IRS for Rel-19 and beyond.
