Mitigating interference in a wireless communication system

摘要

A method of mitigating interference between carrier frequency bands of a carrier aggregation scheme. The method comprises: at a wireless device, receiving a first signal on a first carrier frequency band of the carrier aggregation scheme; mixing a second signal onto a second carrier frequency band of the carrier aggregation scheme and transmitting the second signal from the wireless device; executing code on a processing apparatus of the device to generate a reconstructed interference signal, by mixing an instance of the signal with a frequency location of an interfering harmonic from the second carrier frequency band falling in the first carrier frequency band; and removing the reconstructed interference signal from the first signal.
