Method for transmitting control signal in multiple antenna system

The present invention relates to a method of transmitting a control signal for transferring the separation of the stream-specific control information in a multiple antenna system for performing a different control for each antenna with respect to the plurality of transmission streams as an independent common control channel downlink via. The present invention has an effect that can be transmitted and received efficiently stream in the data multi-antenna system by transmitting to each other using the OVSF code or separate stream by a control signal using a code re-transmitted.
