System and Method for Interference Mitigation in a Wireless Communications System

A method for interference mitigation by a communications device, wherein the communications device is served by a serving controller that is one of a plurality of controllers, the method comprising:

• receiving configuration information from the serving controller;
• measuring channels between the communications device and controllers in a subset of the plurality of controllers, the subset including the serving controller;
• computing a first indicator of operating conditions at the communications device based on the measured channels and the configuration information;
• transmitting the first indicator to the serving controller;
• receiving a second indicator from the serving controller, the second indicator indicating an assigned transmission opportunity;
• and
• transmitting to the serving controller at the assigned transmission opportunity.

A communications device comprising:

• a receiver coupled to an antenna, the receiver configured to receive signals detected by the antenna;
• a transmitter coupled to the antenna, the transmitter configured to transmit signals using the antenna;
• a measure channel unit coupled to the receiver, the measure channel unit configured to measure a quality of a channel between a controller and the communications device;
• and
• a processor coupled to the measure channel unit, the processor configured to compute link gain imbalances for a plurality of channels based on an output of the measure channel unit, and to compute an indicator based on the link gain imbalances and configuration information received from a controller serving the communications device.
