  • Patent number: 9363815
    Abstract: The present invention provides a method for scheduling a SDMA user group in an MU MIMO system and a base station. The method comprise the following steps: calculating, according to channel state information, a projection matrix of a channel matrix of each user in a user group on a joint channel matrix of other users in the same user group, where the user group is selected from a plurality of users; calculating a capacity metric of the user group according to the projection matrixes; and selecting an optimal user group according to the metrics of a plurality of user groups. The present invention effectively eliminates the MUI on terminal users at the transmitter side, and reduces the computational complexity.

  • Publication number: 20140185700
    Abstract: The present invention relates to the field of communications technologies and discloses a method and an apparatus for linear precoding in a multi-user multiple-input multiple-output system, which can reduce computational complexity, improve system efficiency, and enhance system robustness by using a linear precoding technology in the case of imperfect CSI. According to the solutions provided in embodiments of the present invention, a first matrix is determined according to channel information of the system; an equivalent-channel matrix is acquired according to the first matrix; the equivalent-channel matrix is decomposed, and a second matrix is obtained through computation; a precoding matrix is obtained according to the first matrix and the second matrix, so that a power balance is achieved between spatial streams of each user after two signals to be concurrently transmitted are processed by using the precoding matrix.
