ABSTRACT:
Embodiments described herein provide for reducing cellular co-interference. A primary cellular device is selected. A secondary cellular device that causes co-interference with the primary cellular device is also selected. Whether the primary cellular device is a transmitting device or a receiving device is determined. Upon determining that the primary cellular device is a transmitting device, a first hush command is transmitted to the primary cellular device. Upon determining that the primary cellular device is a receiving device, a second hush command is transmitted to the secondary cellular device. The first hush command instructs the primary cellular device to increase a first transmit power from the primary cellular device to a cellular tower. The second hush command instructs the secondary cellular device to decrease a second transmit power from the secondary cellular device to the cellular tower.
