Abstract

A method for providing overload or noise protection may include applying an amplification factor to a first-band signal transmitted in a first frequency band. The first frequency band may include a first uplink band and a first downlink band. The amplification factor may be applied by an amplification circuit configured for signals transmitted in the first frequency band. The method may further include detecting a second-band signal transmitted in a second frequency band. The second frequency band may include a second uplink band and a second downlink band. Additionally, the method may include adjusting the amplification factor based on the detected second-band signal.
