Provided are a channel information determination method and apparatus, the method comprising: sending a channel detection request frame to a station (STA), wherein the channel detection request frame is used to request for the sending of a channel detection signal to the STA, and the channel detection request frame carries a system frame number (SFN) used to determine an orthogonal codeword index value and/or a subcarrier index location configured on each antenna of an access point (AP); and sending a channel detection signal frame to the STA, wherein the channel detection signal frame carries the channel detection signal, and the orthogonal codeword index value and/or the subcarrier index location and the channel detection signal are used to determine channel information between the station (STA) and the AP. By means of the present invention, the problem in the related art that channel detection efficiency is low is solved, thereby achieving the effect of improving the channel detection efficiency. |
