  • Publication number: 20240129704
    Abstract: Embodiments include methods for a user equipment (UE) configured to receive public warning system (PWS) messages from a radio access network (RAN) comprising a plurality of cells. Such methods include receiving, via a first cell having a first ground coverage and a first aerial coverage, a PWS message having a relevant area within a second ground coverage of a second cell but not within the first ground coverage. Such methods include determining whether the PWS message is applicable to the UE based on a first indication of the relevant area, a second indication of relevant altitudes for the PWS message, a third indication of applicability of the PWS message to aerial UEs, and/or a type of signaling by which the PWS message is received. Other embodiments include complementary methods for RAN nodes and core network (CN) nodes, as well as UEs and network nodes configured to perform such methods.
