Methods and apparatus for mitigating interference between co-located collaborating radios

A method of mitigating out of band emissions received at a first radio that communicates with a first base station within a first frequency band, and which was transmitted by a second radio configured to communicate with a second base station within a second frequency band, the method comprising:

• transmitting a first control signal from said first base station to said first radio to alert said first radio that a subsequent transmission is forthcoming from said first base station to said first radio;
• communicating a second control signal from said first radio to said second radio in response to said first control signal;
• transmitting an interim scheduling request from said second radio to said second base station based on said second control signal;
• and
• executing a mitigation protocol in response to said interim scheduling request.

A system for mitigating radio interference from out of band emissions, comprising:

• a first mobile device configured to communicate with a first base station in a frequency range of 769 to 805 megahertz;
• a second mobile device co-located with said first mobile device and configured to communicate with a second base station in a frequency range of 777 to 798 megahertz using OFDMA modulation;
• and
• a data link connecting said first and second mobile devices and configured to communicate information indicating a threshold interference value from said first mobile device to said second mobile device;
• wherein said second mobile device is configured to send an interim scheduling request to said second base station upon receipt of said threshold interference value from said first mobile device.
