Query: Rate-Splitting Multiple Access for 6G -- Part II: Interplay with
  Integrated Sensing and Communications   This letter is the second part of a three-part tutorial focusing on
rate-splitting multiple access (RSMA) for 6G. As Part II of the tutorial, this
letter addresses the interplay between RSMA and integrated radar sensing and
communications (ISAC). In particular, we introduce a general RSMAassisted ISAC
architecture, where the ISAC platform has a dual capability to simultaneously
communicate with downlink users and probe detection signals to a moving target.
Then, the metrics of radar sensing and communications are respectively
introduced, followed by a RSMA-assisted ISAC waveform design example which
jointly minimizes the Cramer-Rao bound (CRB) of target estimation and maximizes
the minimum fairness rate (MFR) amongst communication users subject to the
per-antenna power constraint. The superiority of RSMA-assisted ISAC is verifed
through simulation results in both terrestrial and satellite scenarios. RSMA is
demonstrated to be a powerful multiple access and interference management
strategy for ISAC, and provides a better communication-sensing trade-off
compared with the conventional benchmark strategies. Consequently, RSMA is a
promising technology for next generation multiple access (NGMA) and future
networks such as 6G and beyond.
