Patent ID: 8600370

Claim:
A method for adaptive pilot power transmission for a home evolved NodeB (HeNB) in a cell, the method comprising: establishing, by the HeNB, a re-selection area around the HeNB in accordance with an offset factor, an HeNB pilot power level of the HeNB, and a path loss; measuring, by the HeNB, a pilot power of a pilot signal received from a macro evolved NodeB (eNodeB); estimating, by the HeNB, an updated path loss in accordance with the measured pilot power; and adjusting, by the HeNB, the HeNB pilot power level in accordance with the updated path loss in order to maintain the re-selection area around the HeNB without adjusting the offset factor, wherein adjusting the HeNB pilot power level in accordance with the updated path loss in order to maintain the re-selection area around the HeNB without adjusting the offset factor comprises adjusting the HeNB pilot power level to maintain a radius of the re-selection area above or below a threshold.
