Poster Abstract: CARTS: Cooperative and Adaptive Resource Triggering for 5G ISAC

This poster presents CARTS, an adaptive 5G uplink sensing scheme that jointly uses the estimated CSI from both data channel reference signal (DMRS) and channel sounding reference signal (SRS) to improve the UE sensing capacity with minimal degradation in communication performance. In order to efficiently combine the estimated CSIs from these two reference signals, CARTS features a real-time SRS triggering algorithm to complement the channel estimations from the DMRS. Besides, to address asynchornization issues caused by DMRS and SRS, which are sampled at different time and frequency bands, CARTS applies a new channel stitching and compensation method.
