Adjusting transmit power across a network
First Claim
1. A method for adjusting transmit power in a wireless network, comprising:
- identifying a selected base station with a first coverage area for adjustment of transmit power;
identifying a plurality of neighboring base stations with coverage areas nearby the first coverage area;
retrieving a plurality of signal strength measurements from a plurality of mobile devices within the coverage areas of the plurality of neighboring base stations;
calculating a metric corresponding to a number of mobile devices within the coverage areas of the plurality of neighboring base stations that would be positively impacted by a decrease in power at the selected base station;
calculating a first metric corresponding to a number of mobile devices negatively impacted by an increase in power at the selected base station; and
sending an instruction, based on the metric, for adjustment of transmit power to the selected base station.

7. A method for adjusting transmit power in a wireless network, comprising:
-
identifying a selected base station with a first coverage area for adjustment of transmit power; identifying a plurality of neighboring base stations with coverage areas nearby the first coverage area; retrieving a plurality of signal strength measurements from a plurality of mobile devices within the coverage areas of the plurality of neighboring base stations; calculating a first metric corresponding to a number of mobile devices within a coverage areas of the plurality of neighboring base stations that would be negatively impacted by an increase in power at the selected base station; sending an instruction, based on the first metric, for adjustment of transmit power to the selected base station; subtracting a number of mobile devices that would be positively impacted by the decrease in power from a number of mobile devices that would be negatively impacted by the increase in power to obtain a first net number; subtracting a number of user equipments reporting deterioration in signal to interference ratio (SINR) by the decrease in power from a number of user equipments reporting improvement in SINR by the increase in power to obtain a second net number; and adding the first net number to the second net number to obtain a final number for determining whether to adjust the transmit power at the selected base station. - View Dependent Claims (8, 9, 14, 15, 16, 17, 18, 21)
