摘要：
Disclosed is a method and an apparatus for multiplexing and transmitting/receiving an ACK/NACK resulting from use of a HARQ scheme in an OFDMA system. Frequency and code multiplexing methods are combined with regard to the ACK/NACK to reduce signaling overhead. Frequency multiplexing is conducted by using the MCS level adopted by scheduling channels to improve the ACK/NACK transmitting performance, and code multiplexing is conducted to allocate ACK/NACK resources by using the index of the scheduling channels.
