Abstract: 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.

Abstract: 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) 11 by means of receiving from end-user equipment 27 data requests over a DSL uplink together with identification of at least one DTTV transmitter 21 23. The ISP/CP 11 provides an overlay controller 26 which causes routing of the requested data over a selected DTTV transmitter 21. At the end-user equipment, the requested data can be received from the DTTV broadcast and extracted for output.
