A method, user equipment (UE) and basestation are provided, wherein the UE is configured to send battery status data to the basestation and, in response, the basestation is adapted to improve the Quality of Service for the UE.

User equipment battery consumption

This disclosure provides a device and method of aligning a transmission frame in a Time Division Duplexing network, wherein the transmission frame includes a sequence of units separated by transition points, wherein each unit includes one or more resource slots in a transmission direction, the method comprising: allocating a transmit power level to a plurality of resource slots in a unit, wherein a transmit power for a first resource slot of the plurality of resource slots is greater than the transmit power for a second resource slot of the plurality of resource slots; measuring the transmit power of a TDD transmission received from an external node to determine a peak transmit power of the received TDD transmission; and substantially aligning the first resource slot to coincide with the peak transmit power of the received TDD transmission.

Power based frame timing synchronization for a time-division duplexing network

Embodiments herein provide systems and methods for sending broadband data to end-users over a DTTV broadcast transmission. Systems and methods for receiving such data are also described. A wireless overlay system is set up by an Internet Service Provider/Communications Provider (ISP/CP)by means of receiving from end-user equipmentdata requests over a DSL uplink together with identification of at least one DTTV transmitter. The ISP/CPprovides an overlay controllerwhich causes routing of the requested data over a selected DTTV transmitter. At the end-user equipment, the requested data can be received from the DTTV broadcast and extracted for output.
