Systems and methods for determining a power option for an access node
First Claim
1. A method for determining a power option for an access node, comprising:
- retrieving a plurality of power options for transmitting a first signal from a first access node, wherein a first plurality of wireless devices are in communication with the first access node and the first signal comprises a reference signal;
estimating a service metric for each power option, the service metric being based on met application requirements for the first plurality of wireless devices when the first signal is transmitted according to each power option;
estimating an interference metric for each power option, the interference metric being based on an overlap between a signal area for the first access node when the first signal is transmitted according to each power option and a signal area for a second access node, wherein estimating the interference metric further comprises;
ascertaining locations for a second plurality of wireless devices in communication with the second access node; and
estimating, for each of the power options based on transmission of the first signal according to each power option, the interference metric based on the ascertained locations for the second plurality of wireless devices;
selecting one of the plurality of power options based on the estimated service metric and the estimated interference metric; and
transmitting the first signal according to the selected power option.

Abstract
Systems and methods are described for determining a power option for an access node. Application requirements for a first plurality of wireless devices in communication with a first access node may be identified for each wireless device. The number of wireless devices that comprise a met application requirement may then be determined. When that number meets a first criteria, a plurality of power options for transmitting a first signal may be determined. For each power option, a second number of the first plurality of wireless devices and a third number of wireless devices in communication with a second access node may be estimated. Based on the estimated numbers for the determined power options, a power option may be selected and the first access node may transmit the first signal according to the selected power option.
