The SATIABLE project aims to study the impact of the satellite (GEO, MEO, and LEO), and in general NTNs, in an IAB scenario, envisaging a new topology in which the satellite can be integrated as an IAB-node or an IAB-donor. The study considers the low-level protocols of the 3GPP-NR stack for the access (PHY, MAC, RLC) and for the backhaul (BAP), compliant with 3GPP Rel-17. Furthermore, aspects of the RF component are analysed, taking into account the current specification for the satellite transmissions (i.e., frequency, multiplexing scheme, etc). Accordingly, new IAB NTN scenario are proposed, discussed, and finally validated by system-level simulations.
