Abstract:
1. A method for transmitting a data signal in a multiple-input multiple-output mobile communication system comprising: communicating the data signal using a plurality of transmitting antennas and a plurality of receiving antennas; and communicating a control signal using the plurality of transmitting antennas and the plurality of receiving antennas, wherein each data signal is transmitted through the plurality of transmitting antennas, wherein each transmitting antenna respectively transmits the data signal with different control signals, wherein the control signals are transmitted through at least one downlink control signal transport channel, wherein the control signal comprises control information associated with one or more modulation methods or control information associated with the number of channelization codes that are respectively different in each transmitting antenna, and retransmission, wherein the channelization code is a code having same orthogonal properties as an OVSF code, wherein each channel of the downlink control signal transport channels transmits the same terminal ID, and wherein in the respective downlink control signal transport channels, each control signal is transmitted by using a new combination with respect to a field of each channel including a part to which the specific terminal ID is scrambled.
