Abstract: A system for interference mitigation through carrier aggregation may include one or more processors and a memory. The memory may include instructions that, when executed by the one or more processors, cause the one or more processors to: provide data transmissions and control transmissions to a wireless device over a primary component carrier, determine that interference exists on the primary component carrier, and switch at least a portion of the data or control transmissions to a secondary component carrier in response to determining that the interference exists on the primary component carrier, while maintaining connectivity on the primary component carrier.

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: A wireless communication device communicating with a serving base station in a wireless communication environment may have one or more applications running. When seeking to handover from the serving base station to a target base station, the wireless communication device adjusts the configurations of the applications based on the new communication link properties. Likewise, when an application is loaded that prefers communication link properties that exceeds a current communication link's capabilities, the wireless communication device may seek out and hand over to other communication links. By cooperatively coordinating the functionality of installed applications with communication link properties, the wireless communication device can maintain high levels of device and application functionality.
