Abstract

Embodiments of present invention provide a method for optimizing the rank of channel matrix, a wireless base and a mobile station. The method for optimizing the rank of channel matrix according to an embodiment of the present invention is applied to a wireless base to which multiple mobile stations are connected. The method includes: obtaining the historical state data of the multiple mobile stations; determining the optimal rank of channel matrix of a first mobile station of the multiple mobile stations according to the obtained historical state data of the multiple mobile stations; and transmitting to the first mobile station the optimal rank indicator indicating the optimal rank so as to cause the first mobile station to set its rank of channel matrix to be the optimal rank indicated by the optimal rank indicator.
