Abstract
The present disclosure provides a transmit antenna switching method and a terminal device. The method includes: when the terminal device is in a dual-network connected state, determining a first network used to transmit control plane data and a second network only used to transmit user plane data, where the dual-network connected state is that the terminal device is simultaneously connected to the first network and the second network; determining, based on a transmit antenna used by the first network, a first transmit mode for switching an SRS antenna operating in the second network; and performing the SRS antenna switching based on the first transmit mode by using a first antenna set, where the first antenna set is all antennas used for the dual-network connected state included in the terminal device except the transmit antenna used by the first network.
