POWER BASED FRAME TIMING SYNCHRONISATION FOR A TIME-DIVISION DUPLEXING NETWORK

摘要

This invention provides a device and method of aligning a transmission frame in a Time Division Duplexing, TDD, 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 the steps of: 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.
