1. A method for improving coverage and capacity of a wireless network having multiple cells, comprising:
- receiving one or more measurement reports associated with communications in the wireless network for at least one of the multiple cells during a first period;
assigning two or more status labels to a cell in the wireless network based on the one or more measurement reports, the two or more status labels associated with different cell status categories; and
instructing the cell to adjust an antenna tilt, a transmit power level, or both based on at least a combination of the two or more status labels, wherein the antenna tilt or transmit power level is used to communicate wireless signals in the cell during a second period.

Abstract
Methods and apparatus are provided for adjusting configuration parameters, such as antenna tilt or transmit power, of a plurality of cells in a wireless network based on measurement reports received during a data collection period of the wireless network, so that coverage and capacity of the wireless network may be improved. Cell status labels or blames are assigned to each of the cells based on the measurement reports, and configuration parameters of the cells are adjusted based on the assigned cell status labels or blames.
