Abstract: This application provides a beam training method and apparatus. The method includes: generating and sending a set up frame, where the set up frame includes M pieces of time information, each piece of time information corresponds to one receiving device in the M receiving devices, each piece of time information is used to indicate a feedback information sending moment of the corresponding receiving device, each piece of time information is further used to indicate an acknowledgment information receiving moment of the corresponding receiving device, receiving a sector sweep SSW frame, generating feedback information based on the SSW frame, sending the feedback information at a feedback information sending moment indicated by corresponding time information, receiving, at an acknowledgment information receiving moment indicated by the corresponding time information, acknowledgment information. Therefore, a training time can be shortened, and signaling overheads can be reduced.

Abstract: This application provides an information feedback method and a related apparatus. In the method, a first apparatus sends, to a second apparatus, a first frame that carries a first field used to perform channel estimation, and the first apparatus receives a first feedback frame from the second apparatus. The first feedback frame includes channel state information CSI, the CSI is CSI from the first apparatus to the second apparatus, the CSI is obtained by the second apparatus by performing channel estimation based on the received first field and a second field, and the second field is not the first field.
