Apparatus and method for controlling transmission mode in a MIMO mobile communication system

摘要

An apparatus and method for controlling a transmission mode in a MIMO mobile communication system are provided. In a receiver in the MIMO mobile communication system, an error checker checks errors in received data and outputting an error check result. A feedback portion adaptively changes a threshold associated with a channel state according to the error check result, and determines a transmission mode by comparing the changed threshold with a measured CQI, and feeds back transmission mode information to a transmitter.
