Abstract: In an embodiment an interference cancellation method includes generating, by a first device, a first packet, wherein the first packet comprises a first group of elements, a second group of elements, and user data, the first group of elements being different from the second group of elements and sending, by the first device, the first packet to a second device by using at least one pair of subcarriers, wherein two subcarriers in the at least one pair of subcarriers are symmetrical with respect to a direct current subcarrier, and wherein the first packet is usable by the second device to cancel interference in the user data based on the first group of elements and the second group of elements.

Abstract: This application discloses a channel sounding method and a communication apparatus. The method includes: A first access point receives a channel transfer command frame from a controller or a central access point, and sends a channel transfer frame to a second access point. The channel transfer command frame indicates the first access point to send a channel sounding result of at least one station to the second access point. The channel transfer command frame includes a first sounding dialog token number. The channel transfer frame carries a channel sounding result corresponding to a first sounding dialog token in channel sounding results of a plurality of stations. The first access point forwards the channel sounding result of the at least one station to the second access point.
