12. The method of claim 11 , wherein the received power comprises a first received power, and wherein determining the second received power value comprises performing one or more operations comprising:
measuring, at the first private access point, a second received power received from the second private access point; and
receiving the second received power value from an access terminal configured for communication with the first private access point in the wireless communication network, the second received power value being indicative of a third received power received by the access terminal from the second private access point.
13. The method of claim 1 , further comprising:
receiving one or more other transmit power values at the first private access point, the one or more other transmit power values being indicative of one or more other transmit powers of one or more other private access points in the wireless communication network, respectively; and
wherein determining the first transmit power value comprises:
determining the first transmit power value using at least the second transmit power value and the one or more other transmit power values.
14. One or more non-transitory computer-readable media configured to store instructions that are executable by a first private access point in a wireless communication network to perform operations comprising:
transmitting, from the access signals at a first transmit power, the first transmit power corresponding to a first transmit power value;
receiving, at the first private access point, a second transmit power value indicative of a second transmit power of a second private access point in the wireless communication network; and
determining the first transmit power value, at the first private access point, using at least the second transmit power value; and
determining a received power value by measuring a received power at the first private access point, the received power being due to an ambient noise and an interference power received from a macro access point.
