Abstract
Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

(canceled)
A method of wireless communication, comprising:
- receiving at a home femto node a measurement report from a home access terminal, the measurement report conveying transmit power measurements of neighboring femto nodes taken by the home access terminal;
- ranking the neighboring femto nodes based on the measurement report according to their respective transmit powers;
- and
- sending a message to the highest ranking neighboring femto node requesting a reduction in transmit power.
An apparatus of wireless communication, comprising:
- a processor configured to:
- receive at a home femto node a measurement report from a home access terminal, the measurement report conveying transmit power measurements of neighboring femto nodes taken by the home access terminal,
- rank the neighboring femto nodes based on the measurement report according to their respective transmit powers, and
- send a message to the highest ranking neighboring femto node requesting a reduction in transmit power;
- and
- memory coupled to the processor and configured to store related data and instructions.
An apparatus of wireless communication, comprising:
- means for receiving at a home femto node a measurement report from a home access terminal, the measurement report conveying transmit power measurements of neighboring femto nodes taken by the home access terminal;
- means for ranking the neighboring femto nodes based on the measurement report according to their respective transmit powers;
- and
- means for sending a message to the highest ranking neighboring femto node requesting a reduction in transmit power.
An non-transitory computer-readable medium comprising code, which, when executed by a processor, causes the processor to perform operations for wireless communication, the non-transitory computer-readable medium comprising:
- code for receiving at a home femto node a measurement report from a home access terminal, the measurement report conveying transmit power measurements of neighboring femto nodes taken by the home access terminal;
- code for ranking the neighboring femto nodes based on the measurement report according to their respective transmit powers;
- and
- code for sending a message to the highest ranking neighboring femto node requesting a reduction in transmit power.
