Claim:
1. A link adaptation feedback method, comprising: receiving, by a transmitting device, a link adaptation feedback frame sent by a receiving device, wherein the link adaptation feedback frame carries space-time block coding (STBC) type indication information; and determining, by the transmitting device, according to the space-time block coding type indication information, information about use of space-time block coding by a data frame related to the link adaptation feedback frame, wherein the determining, by the transmitting device, according to the space-time block coding type indication information, information about use of space-time block coding by a data frame related to the link adaptation feedback frame comprises at least one of: if the space-time block coding type indication information indicates that the link adaptation feedback frame is fed back with respect to a frame not using space-time block coding, determining, by the transmitting device, that the data frame related to the link adaptation feedback frame does not use space-time block coding; and if the space-time block coding type indication information indicates that the link adaptation feedback frame is fed back with respect to a frame using space-time block coding, determining, by the transmitting device, that the data frame related to the link adaptation feedback frame uses space-time block coding.
