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: A system and method is provided for encoding k input symbols into a longer stream of n output symbols for transmission over an erasure channel such that the original k input symbols can be recovered from a subset of the n output symbols without the need for any retransmission. A symbol is a generic data unit, consisting of one or more bits, that can be, for example, a packet. The system and method utilize a network of erasure codes, including block codes and parallel filter codes to achieve performance very close to the ideal MDS code with low encoding and decoding computational complexity for both small and large encoding block sizes. This network of erasure codes is referred to as a supercharged code. The supercharged code can be used to provide packet-level protection at, for example, the network, application, or transport layers of the Internet protocol suite.

Abstract: Embodiments provide power saving schemes for a user equipments (UE) in low power supply state. The power saving schemes include network-assisted power saving schemes and UE-triggered power saving schemes. Network-assisted power saving schemes require network awareness of the low power supply state of the UR Thus, embodiments provide the UE the ability to communicate its power supply state to the network. UE-triggered power saving schemes may or may not require network awareness of the UE s power supply state andd/or of the execution of the HE-triggered power saving scheme at the UE.
