Abstract:
Apparatuses, systems, and methods for emergency communications (e.g., voice calls and/or SMS messages) for UE's without cellular coverage (e.g., in non-cellular coverage). A UE may establish, while out of range of cellular service, a peer-to-peer communication session with a relay UE using a channel in an unlicensed frequency band. The UE may transmit, using the peer-to-peer communication session, an emergency notification to the relay UE. The emergency notification may include an approximate location of the UE. Further the UE may communicate with a Public Safety Answering Point (PSAP), where the communications may be relayed between the UE and the PSAP by the relay UE. The approximate location of the UE may be based, at least in part, on a location of the relay UE and determining the approximate location of the UE may include performing a ranging procedure with the relay UE.
