Method and device for rank adaptation
The present invention discloses a method and apparatus for rank self-adaptation. The method comprises: a base station receiving ranks reported by a user equipment via a rank receiving window, determining a rank at the current moment based on a distribution state of each rank in the rank receiving window at the current moment, and determining the number of independent channels used for sending downstream data to the user equipment based on the rank at the current moment. The present invention can reasonably forecast change of ranks of MIMO channels so as to better use MIMO channel resources to perform data transmission and improve the throughput rate of the MIMO channels.
