APPARATUS AND METHOD FOR TRANSMITTING OF CHANNEL QUALITY INDICATOR AND ACKNOWLEDGEMENT SIGNALS IN SC-FDMA COMMUNICATION SYSTEMS

摘要

PURPOSE: An apparatus and a method for transmitting of channel quality indicator and acknowledgement signals in a sc-fdma communication systems are provided to multiplex ACK/NACK data bit at a CQI transmission frame. CONSTITUTION: A signal comprises one or more slots. The slot comprises first and second symbols. A reference signal is transmitted from first symbols. The information bits of a second type are transmitted from second symbols. A transmission method of the information bits of the first type using signal comprises a process of multiplying the first quadrature cover in case of the information bit and first symbols of the first type having the first value. A transmission method comprises a process of multiplying the second orthogonal cover in case of the information bit and first symbols of the first type having the second number. The transmission method comprises a process of transmitting first symbols.
