<p>Embodiments of the present invention provide a method and an apparatus for configuring a transmission mode, where the method includes: obtaining channel matrix information, where the channel matrix information is any one of the following: a precoding matrix indicator which most matches a current uplink channel matrix of a terminal, a current downlink precoding matrix indicator of the terminal, an uplink channel matrix of the terminal and the precoding matrix indicator which most matches the current uplink channel matrix of the terminal, and the uplink channel matrix of the terminal and the current downlink precoding matrix indicator of the terminal; determining performance of data transmission performed by adopting a closed-loop mode and an open-loop mode according to the channel matrix information, and selecting the data transmission mode according to the determined performance of data transmission, where the data transmission mode includes the open-loop mode, the closed-loop mode. A transmission mode is determined by adopting channel spatial correlation and a speed, so as to select the transmission mode more accurately, thereby promoting data transmission efficiency.</p> |
