METHOD FOR TRANSMITTING UPLINK SIGNALS

摘要

A method for transmitting an uplink signal is provided to improve a receiving reliability of a signal by efficiently arranging an ACK/NACK signal and a control signal on a resource region according to priority. A control signal and a data signal are serially multiplexed(603). A multiplexed signal is successively mapped inside a specific resource region by a time-first mapping method. The specific resource region includes a plurality of symbols and a plurality of virtual subcarriers. An ACK(ACKnowledgement)/NACK(Negative-ACKnowledgement) signal is arranged on both symbols adjacent to a symbol in which a reference signal is transmitted among a plurality of symbols. The ACK/NACK signal is overwritten in a part of the multiplexed signal.
