1. A communication apparatus, comprising:
- a receiver configured to receive, using a first wireless communications technology, measurement reports from an access terminal conducting a training walk calibration procedure for a network of femtocells, wherein the measurement reports are associated with measurements during the training walk calibration procedure; and
a processing system configured to control transmit power for a second wireless communication technology of at least one of the femtocells based on the received measurement reports, wherein the transmit power is controlled to meet at least one criterion at one or more locations associated with the measurements during the training walk calibration procedure, and the second wireless communication technology being different from the first wireless communication technology.

Abstract
A power calibration scheme adjusts power levels of network of femtocells based on macro signals seen at different points in and around a coverage area and based on the mutual positions of the femtocells (e.g., based on femtocell signals seen at these points). The power calibration scheme thus facilitates a good balance between providing a desired level of coverage and mitigation of interference to nearby macrocells and femtocells.
