Abstract: Example Wi-Fi sensing-supported communication methods and apparatus are described. In one example method, a transmit end sends a request frame to a receive end, where the request frame includes a first field and a second field. The first field indicates a first type, and the first type is a type of data requested by the transmit end from the receive end. The second field indicates a condition to be met by data of the first type. The receive end is enabled to feed back, based on the request frame, data that is of the first type and that meets the condition, to efficiently obtain required data from another Wi-Fi device.

Abstract: The present disclosure relates to signal transmission methods and apparatuses. One example method includes spreading a preamble symbol based on a first spreading code sequence to generate a first signal, and sending the first signal to a receiver. The first signal is used to determine a channel impulse response. The first spreading code sequence includes a plurality of spreading code groups, each spreading code group includes a plurality of same spreading codes and at least one guard symbol, at least one of a first bit or a last bit of each spreading code group is a guard symbol, and the plurality of spreading code groups include at least two spreading code groups with different spreading codes.

Abstract: A method includes: determining a plurality of first subcarrier data items on a plurality of first subcarriers of a first frequency subband; performing first phase rotation on each first subcarrier data item based on a mixing frequency and a first reference frequency corresponding to the first frequency subband; determining a to-be-transmitted signal based on a plurality of first subcarrier data items obtained through first phase rotation; and sending the to-be-transmitted signal. In this way, phase rotation can be performed based on at least the first reference frequency, so that modulation can be correctly implemented without a need to know a mixing frequency of a receiving end. In addition, there is no need to notify the receiving end of the used mixing frequency, and the receiving end can correctly demodulate a received signal even if the receiving end does not know the mixing frequency.

Abstract: A receiver module that is communicatively connected to a plurality of Wi-Fi receiver chains is disclosed. The receiver module is configured to selectively switch the states of a plurality of Wi-Fi receiver chains between an “ON” state and an “OFF” state based on a signal quality parameter measured by each of these receiver chains.
