Claim 16:
17. The terminal device of claim 11, wherein the processor is configured to execute the instructions stored in the memory, so that the terminal device further performs:
detecting a downlink received energy of the at least two antennas and that is within downlink estimated time;
determining whether an absolute value of a second difference is greater than or equal to a preset energy threshold, wherein the second difference is a difference between a downlink received energy of an antenna with a highest downlink received energy in the at least two antennas and a downlink received energy of an antenna with a lowest downlink received energy in the at least two antennas; and
when the absolute value of the second difference is greater than or equal to the preset energy threshold, determining whether a spectrum effectiveness of the current transmit antenna is less than a preset switching threshold; and
when the spectrum effectiveness of the current transmit antenna is less than the switching threshold, switching the current transmit antenna to an antenna with highest spectrum effectiveness in the at least two antennas.
