Patent ID: 8909278

Claim:
A method comprising: receiving, at a home base station, signal to interference and noise ratio (SINR) data from at least one access terminal; calculating a coverage failure probability based at least in part on the SINR data, the calculating comprising: determining that the at least one access terminal is located within a threshold distance of the home base station, building a histogram associated with the at least one access terminal based on the received SINR data, calculating a probability distribution function for the at least one access terminal based upon the histogram; calculating the coverage failure probability function by computing a weighted sum of probability distribution functions; calculating a coverage failure complementary cumulative distribution function based upon the weighted sum; and averaging the coverage failure probability function over a period of time to produce the coverage failure probability; determining to adjust a transmission power of the home base station based at least in part on the coverage failure probability; and adaptively adjusting the transmission power of the home base station based at least in part on the coverage failure probability including: setting the transmission power to a quiescent power level in response to determining that there is no active connection on the home base station.
