Abstract: Embodiments include methods, performed by a mobile terminal (MT) of an integrated access backhaul (IAB) node in a radio access network (RAN), for reporting capabilities of cells in the RAN. Such methods include detecting one or more cells in the RAN and determining whether the one or more cells support IAB (e.g., by receiving information broadcast by the respective cells). Such methods also include sending, to a centralized unit (CU, e.g., of abase station) in the RAN, a measurement report including an indication of whether the one or more cells support IAB. Various techniques can be used to indicated IAB support. In some embodiments, the MT can receive a reconfiguration message, from the CU, for a handover to one of the cells that supports IAB. Other embodiments include complementary methods performed by CUs, as well as MTs and CUs configured to perform such methods.
