More Information
Summary:Disclosed is a transmission method for a downlink control signal in a MIMO communication system where multiple transmit antennas and multiple receive antennas are used, in which each data transmitted from the multiple transmit antennas is transmitted with a different control signal through one downlink control signal transmission channel. The transmission method for a downlink control signal in a MIMO communication system efficiently transmits or receives data by transmitting control information such as a different modulation method and the number of OVSF codes of each transmit antenna to a mobile station. Also, a control channel is similar to that used in the conventional HSDPA system, thus allowing backward compatibility. Additionally, the transmission method can be applied not only for data transmitted to each antenna being composed of one packet but also for data transmitted to each antenna being composed of multiple packets.
