Method and apparatus for multi-input multi-output downlink transmission control

摘要

A Multi-Input Multi-Output (MIMO) downlink transmission control method that is related to communications technologies is disclosed in embodiments of the present invention. The method includes: obtaining a channel fading change rate and a feedback delay of a user; calculating out a closed-loop MIMO throughput gain according to the channel fading change rate and the feedback delay; and determining a downlink transmission mode according to the closed-loop MIMO throughput gain, wherein the downlink transmission mode includes a closed-loop mode or an open-loop mode. A MIMO downlink transmission control apparatus is also disclosed.
