Patent ID: 7460625

Claim:
In a cellular wireless communication system including a plurality of cells wherein a wireless transmit/receive unit (WTRU) monitors signal strength from a serving cell and at least one neighbor cell for handover, and each cell transmits a unique pilot sequence, a method for canceling cross-correlation noise due to strong serving cell signals, the method comprising: (a) receiving signals from a serving cell and at least one target cell; (b) computing a cross-correlation of a pilot sequence of the serving cell and a pilot sequence of the target cell; (c) computing a target cell correlation by correlating the received signals with the pilot sequence of the target cell; (d) computing a cross-correlation cancellation signal for canceling the cross-correlation noise; (e) subtracting the cross-correlation cancellation signal from the target cell correlation; and (f) processing the result of step (e) for evaluation of handover from the serving cell to the target cell.
