Disclosed are a method for transmitting information in an MU-MIMO system, a station, and an access point. The method comprises: a first station determines multiple first long training sequences to be sent, wherein the multiple first long training sequences comprise at least one phase tracking pilot; and the first station sends the multiple first long training sequences to an access point on multiple symbols, and a second station sends multiple second long training sequences to the access point on the multiple symbols, wherein the multiple second long training sequences comprise at least one phase tracking pilot, a first phase tracking pilot and a second phase tracking pilot occupy different time-frequency resources, the at least one phase tracking pilot comprised in the multiple first long training sequences comprises the first phase tracking pilot, and the at least one phase tracking pilot comprised in the multiple second long training sequences comprises the second phase tracking pilot. By means of the method for transmitting uplink information disclosed in the present invention, a frequency deviation parameter of each station can be determined. |
