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.

Emergency communication in non-cellular coverage

A user equipment (UE) may identify that an emergency call is being initiated and send further messages including the location of the UE. The UE receives emergency location signaling parameters, identifies that an emergency communication has been initiated by the UE based on the emergency location signaling parameters and transmits a message to an endpoint associated with emergency services based on the identification of the emergency message being initiated, wherein the message includes location information for the UE.
