Overview Joint Communications and Sensing in 6G

Speaker: Sheshachalam B. S.

Abstract

Similar to Positioning services already integrated in LTE, 5G and 5G advanced, sensing capabilities or 'Network as a sensor' are seen as the evolutionary step for inclusion in 6G standardization since positioning is a subset of sensing capabilities. Multiple use cases, apart from the obvious (communication enhancement), justify expansion of cellular service capabilities to sense objects not connected to the network. Several system design factors favour integrating the design of sensing capabilities into mobile networks as compared to mere independent co-existence of these two types of networks. However JCAS systems are in their infancy and significant amount of new research over the next few years will enable an optimized, native design for 6G.The challenges include choice of power efficient waveform, channel modelling, radar interference mitigation methods, sensor fusion, to name a few. However, 6G systems will likely have native AI/ML support, support for Extreme Massive MIMO and D-MIMO that would be welcome tools to be leveraged for processing JCAS signals.

Sheshachalam is the Department Head at Nokia Standards (Strategy & Technology) India He began his career at Motorola (1995) as one of the core developers of CDMA-WILL and RAN products; led CDMA specification team over several years. He currently leads a team of highly motivated researchers primarily in the areas of 3GPP standardization Research for 5G advanced and 6G. At NOKIA he was a member of RAN algorithm innovations team. He has submitted several RAN1 contributions from Nokia and has few 5G RRM SEPs (Standards Essential Patents) including a GlobeComm Publication on 5G RRM. He was also recognised as one among the Top 10 inventors of standards essential patents all time at Nokia Bangalore centre.
