Abstract: A method for avoiding inter-modulation distortion in a communications apparatus capable of supporting carrier aggregation and communicating with a peer communications apparatus in a wireless network via at least a first CC and a second CC includes: determining a frequency adjustment value for adjusting a first oscillating frequency of a first local oscillation signal utilized for processing an RF signal of the first CC or a second oscillating frequency of a second LO signal utilized for processing an RF signal of the second CC when an RF signal or a baseband signal of the second CC is interfered with by an inter-modulation distortion signal contributed by any signal component related to the first CC; and adjusting the first oscillating frequency or the second oscillating frequency according to the frequency adjustment value.
