Claim 0:
1. A transmission antenna switching method, applied to a terminal device and comprising:
in a case that 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;
determining a working mode of the second network in a case that a sounding reference signal (SRS) switching request is received;
determining a priority order of transmission antenna switching in the first network and the second network according to the working mode of the second network; and
performing SRS antenna switching in the first network according to the priority order; wherein
the determining a priority order of transmission antenna switching in the first network and the second network according to the working mode of the second network comprises:
determining that a priority of the first network is lower than a priority of the second network in a case that the second network is in a time division duplex (TDD) working mode; or
determining that a priority of the first network is higher than a priority of the second network in a case that the second network is in a frequency division duplexing (FDD) working mode.
