    Abstract: Methods and nodes are provided, an example method including, when a first node is in a sensing mode, receiving, by the first node, at least one first signal frame from a second node. The example method further includes processing, by the first node, the at least one first signal frame based on a same automatic gain control (AGC) gain. The example method further includes obtaining, by the first node, channel state information (CSI) based on at least one processed first signal frame.

    Abstract: This application provides a method for dynamically switching antennas. User equipment determines an antenna switching sequence based on a networking mode of the user equipment and an actual scenario, and performs antenna switching based on the determined antenna switching sequence. When the technical solutions of this application are implemented, a problem that a conflict exists in an antenna switching process is effectively resolved without adding hardware.

    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.
