Downlink power control for interference mitigation in competing communication systems

A wireless communication system capable of operating in a Radio Frequency (RF) band with a conflicting additional wireless communication system, the wireless communication system comprising:

• a wireless base station operable to transmit downlink communications to a user equipment (UE) in the RF band and to receive uplink communications from the UE in the RF band;
• and
• a processor that is separate from the UE, the processor being operable to:
• detect the uplink communications from the UE,
• determine a location of the UE based at least partially on the detected uplink communications,
• determine that additional physical layer resources are available to support the UE, the additional physical layer resources including one or more of (i) additional time resources and (ii) additional frequency resources, and
• in response to determining that additional physical layer resources are available to support the UE:
• change a transmit power of the wireless base station,
• direct the UE to reduce its transmit power, and
• change a Modulation and Coding Scheme (MCS) of wireless communication signals between the wireless base station and the UE at least partially based on a communication capability of the UE at the location of the UE,
• to avoid interference with the conflicting additional wireless communication system.

A method operable with a wireless communication system operating in a Radio Frequency (RF) band with a conflicting additional wireless communication system, the method comprising:

• receiving uplink communications from a user equipment (UE) in the RF band via a wireless base station;
• estimating a location of the UE at least partially based on the uplink communications;
• determining that additional physical layer resources are available to support the UE, the additional physical layer resources including one or more of (i) additional time resources and (ii) additional frequency resources;
• and
• in response to determining that additional physical layer resources are available to support the UE:
• changing a transmit power of the wireless base station,
• directing the UE to reduce its transmit power, and
• changing wireless communication resources of the wireless base station allocated to the UE at least partially based on a communication capability of the UE at the location of the UE,
• to avoid interference with the conflicting additional wireless communication system.
