A terminal and method for improving the terminal reception sensitivity; when the terminal works in a time division duplexing mode, the method comprises: in a transmitting time slot, using the frequency of the transmitting voltage control oscillator (VCO) of the terminal as a first frequency; and in a receiving time slot, using the frequency of the transmitting VCO of the terminal as a preset second frequency, the predetermined second frequency differs from the first frequency in the bandwidth of at least one channel. The present invention improves the reception sensitivity of a terminal, reduces the production cost of the terminal, and decreases product size.
