Patent ID: 7974230

Claim:
A method for a low-cost Internet base station (LCIB) to reduce interference with communications between mobile stations and macro-network base stations, each macro-network base station providing service on at least one carrier, each carrier having a forward link and a reverse link, the method comprising: an LCIB storing a baseline level of reverse noise on a reverse link of a first carrier; the LCIB transmitting a pilot beacon, wherein transmitting the pilot beacon comprises transmitting the pilot beacon on a forward link of the first carrier at a first power level; while transmitting the pilot beacon on the forward link of the first carrier, the LCIB measuring a current level of reverse noise on the reverse link of the first carrier, and calculating a current first-carrier reverse-noise rise (RNR) as the difference between the current and baseline levels of reverse noise on the reverse link of the first carrier; and the LCIB determining that the current first-carrier RNR is greater than an RNR threshold, and responsively transmitting the pilot beacon on the first carrier at a second power level, wherein the second power level is lower than the first power level.
