Abstract
Embodiments of this application provide an antenna switching method for a terminal device and an apparatus. The terminal device sends detection packets through at least two antennas within uplink estimated time, obtains, based on response messages corresponding to the detection packets, spectrum effectiveness that is of the at least two antennas and that is within the uplink estimated time, and switches a current transmit antenna of the terminal device based on the spectrum effectiveness of the at least two antennas. In this manner, the terminal device determines, based on the uplink spectrum effectiveness of the at least two antennas, whether to switch the current transmit antenna. Because the uplink spectrum effectiveness of the antennas can accurately reflect a real environment of uplink transmission, antenna switching can be accurately performed. This improves performance of an uplink transmit antenna.
