Abstract: Systems and methods for enabling a group of user equipments located in an emergency area to cooperatively transmit an emergency (SOS) message to a cellular network and to cooperatively receive an SOS message (or response) from the cellular network are provided. Embodiments further provide a scheme for enabling dedicated receivers, and/or user equipments that are attached to the cellular network to serve as relay stations for SOS messages, thereby extending the coverage of the cellular network to the emergency area.

Abstract: Embodiments provide methods and systems for transmitting an emergency (SOS) message from a user (UE) to a cellular network in a highly robust and energy efficient manner. Specifically, embodiments enable the SOS message to be sent in a synchronous manner despite the asynchronous nature of the network, which significantly enhances the probability of successful reception of the SOS message by at least one base station (eNodeB) of the network. Embodiments further provide highly robust SOS message transmission and reception schemes configured to enhance the successful detection and decoding of the SOS message by at least one base station of the cellular network. In addition, embodiments enable the synchronous transmission of the SOS message to the network without requiring network attachment by the UE. This makes embodiments highly suited for emergency situations in which network coverage is affected and can enable significant and precious power savings at the UE.
