Embodiments of the present invention provide a multi-user interference suppression method, terminal and base station, including: performing layer mapping on and precoding service data of each of paired users, to obtain precoded output data ;; and mapping the precoded output data ; and a common pilot sequence to a port of an antenna array, for sending to each user by using the antenna array. Correspondingly, the embodiments of the present invention further provide a data receiving method, base station and terminal. By using a common pilot sequence based on the paired users, the same pilot sequence is used for each user in the paired users of a cell or a collaborative area, which is different from the technical solution in the prior art where a user-specific pilot is used, and pilots of different users must be orthogonal. Therefore, the number of paired users is not limited by the number of orthogonal pilot sequences, thereby better supporting the CoMP mode, and improving accuracy of channel estimation. |
