Dynamic power adjustment for small cells

A non-transitory computer-readable storage medium for use in conjunction with a computer, the computer-readable storage medium storing program instructions, wherein, when executed by the computer, the program instructions cause the computer to perform operations comprising:

• receiving, at an interface circuit in the computer, information specifying received signal strength indication, RSSI, measurements associated with a radio node, one or more neighboring radio nodes of the radio node, or both, wherein the RSSI measurements are performed by the one or more neighboring radio nodes and by one or more electronic devices communicatively attached with the radio node, and wherein the RSSI measurements correspond to a signal transmitted by the radio node using a transmit power;
• calculating, based at least in part on a set of temporal RSSI metrics of the radio node corresponding to the RSSI measurements, a spatial RSSI metric of the radio node;
• and
• providing, from the interface circuit, transmit-power information addressed to the radio node, wherein the transmit-power information corresponds to the spatial RSSI metric and, in conjunction with a first threshold value and a second threshold value, specifies an adjustment of the transmit power within a range of values,
• wherein the adjustment comprises reducing the transmit power when the spatial RSSI metric is greater than the first threshold value and a coverage criterion corresponding to the second threshold value is met, and
• wherein the adjustment comprises increasing the transmit power when the spatial RSSI metric is less than the first threshold value.

A method for adjusting a transmit power, comprising:

• by a computer:

• calculating, based at least in part on a set of temporal RSSI metrics of the radio node corresponding to the RSSI measurements, a spatial RSSI metric of the radio node;
• and
