Abstract
The embodiments of the present disclosure relate to a channel sounding method, a communication device, and a communication system. The channel sounding method is applied to a first device, and comprises: determining a first wireless frame, wherein the first wireless frame identifies dRU information allocated by a first device for channel sounding, the dRU information being determined on the basis of the operating channel bandwidth of a second device and channel puncturing information corresponding to the operating channel bandwidth, and the operating channel bandwidth being greater than or equal to 160 MHz; and sending the first wireless frame. Thus, channel sounding is performed by using dRU under a large bandwidth, thereby further improving a channel sounding mechanism.
