description The invention discloses a method and device for downlink signal transmission in a dual-connection architecture, and a terminal. The method comprises the following steps: when the first signal transmitter, the first signal receiver and the second signal transmitter all work, filtering out a signal in a preset frequency band in a second uplink signal through a notch filter arranged on a first downlink after a higher harmonic signal of the first uplink signal and a second uplink signal enter the first downlink and before the second uplink signal enters a first signal receiver. The device comprises the notch filter arranged on the first downlink in the dual-connection architecture, wherein the notch filter is used for filtering the signal in a preset frequency band in the second uplink signalon the first downlink; the terminal comprises the device. According to the invention, the problems of disconnection and the like caused by poor signal reception of the first signal receiver due to anintermodulation problem ca
