    Abstract: A user-device implemented method includes encoding a first digital signal to generate a first digital baseband signal and modulate the first digital baseband signal to generate one or more RF signals corresponding to one or more frequency bands. The one or more RF signals are transmitted via one or more antennas. Substantially simultaneously with the transmission of the one or more RF signals, a second one or more RF signals is received via the one or more antennas. The second one or more RF signals are demodulated to generate a second digital baseband signal. The first digital baseband signal is subtracted from the second digital baseband signal to generate a modified second digital baseband signal.

    Abstract: A communication device receives data transmissions from a data transmitter. The communication device monitors at least one quality indicator indicative of a quality of service of the data transmissions and/or of a link quality. The monitoring is performed at an application layer of the communication device. An application executed on the application layer of the communication device generates at least one power control message as a function of the monitored at least one quality indicator and transmits the at least one power control message to the data transmitter.

    Abstract: The present invention relates to a method for operating a base station (130) of a radio access network (100). According to the method, a first user equipment (110) within a cell (101) served by the base station (130) is detected and a second user equipment (120) within the cell (101) served by the base station (130) is detected. Furthermore, a relay request is sent (307) to the first user equipment (110). The relay request instructs the first user equipment (110) to relay (310-313) a data communication between the base station (130) and the second user equipment (120).

    Abstract: Embodiments of the invention are directed to systems, methods and computer program products for minimizing data overhead in a cellular network. In one embodiment, a method includes determining, by a mobile device connected to the cellular network via a connection point, that the connection point has limited capacity; determining, by the mobile device, location information including location data indicating a current location of the mobile device; and determining, by the mobile device, an offload alternative connection point based on the determined location of the mobile device. In some cases, the method includes initiating disconnecting of the mobile device from a current connection point; and initiating connecting the mobile device to the offload alternative connection point.
