The present invention relates to the technical field of mobile communications. Disclosed are an information transmitting method and apparatus, which are applied to a wireless local area network adopting uplink MU-MIMO technology, and the wireless local area network comprises a plurality of stations, so as to transmit a plurality of data streams with access points (AP). The method comprises: generating, by the stations, a plurality of long training field (LTF) symbols, R sub-carriers being allocated, on the plurality of LTFs, to any one data stream transmitted by the stations for bearing channel estimation sequences, and the plurality of LTFs comprising a first LTF and a second LTF which satisfy a set condition; and transmitting, by the stations, the plurality of long training fields (LTF). The method and apparatus provided by the present invention solve the problem in the prior art that the correctness of channel estimation is affected by the fact that the orthogonality of a P matrix is affected by carrier frequency offset of the stations. |
