Method and apparatus for allocating feedback channel in multipe antenna communication system

A base station for allocating a feedback channel in a communication system: The present invention relates to a method and apparatus for allocating a feedback channel in a multi-antenna communication system, a multi-user multiple-input multiple-output (MU-MIMO Multi-User Multiple-Input Multiple-Output) in the method of operation, including the step of the procedure for determining a feedback amount according to the procedure and the MIMO transmission environment measuring a MIMO transmission environment, allocating resources in accordance with the amount of feedback, according to the system capacity to the transmission environment, there is an advantage that can be optimized. Multiple input multiple output (Multi Input Multi Output), feedback, layer (layer), rank (rank).
