FIELD: information technology.
SUBSTANCE: method of sending control information in a wireless communication system involves spreading control information across frequency with a discrete Fourier transform (DFT) to obtain frequency-spread data; and spreading the frequency-spread data across time with an orthogonal sequence to obtain output data for the control information.
EFFECT: high efficiency of transmitting control information, particularly CQI and ACK information.
