TRANSMISSION AND RECEPTION METHOD FOR ACK/NAK SIGNALING IN WIRELESS COMMUNICATION SYSTEMS

摘要

A method for transmitting and receiving an ACK(Acknowledgement)/ NAK(Non-acknowledgement) signal in a wireless communication system is provided to reduce interference and a noise by allocating a sequence, which is perpendicular to each other in a time axis, to a terminal. A method for transmitting and receiving an ACK/NAK signal in a wireless communication system includes the steps of: allocating a first resource block and a second resource block of a resource block in a time axis to one terminal at a time axis sequence generation unit(1110), wherein the resource block occupies one symbol in the time axis and occupies N sub-carriers in a frequency axis, N is an even number and is larger than two; allocating the sequence perpendicular to N sub-frequency in the frequency axis to the terminal at a frequency sequence generation unit(1120); if the terminal receives an ACK/NAK bit of a code word having a first binary value, transmitting the sequence with the first resource block, and if the ACK/NAK bit is a second binary value, transmitting the sequence with the second resource block.
