    摘要: A method, a system, a Base Station (BS) and a mobile terminal device for collaborative communication are disclosed, so as to multiplex open-loop and closed-loop users and improve a utilization rate of system frequency spectrum. The method includes receiving CSI sent by a user, in which the CSI is CSI of an LOS signal of the user that is obtained by eliminating CSI of a multi-path signal. The method then obtains CSI of a closed-loop user having a channel that is orthogonal to a channel of the user, and performs pre-coding calculations by using the CSI of the LOS signal of the user and the CSI of the closed-loop user. Communication data is then sent to the user by using the result of the pre-coding calculation.
