Apparatus and method for transmitting and receiving information through fast feedback channel in broadband wireless communication system

A method for transmitting feedback information through a fast feedback channel in a wireless communication system, the method comprising:

• mapping a sequence, corresponding to an index to be fed back, to a first set of resource blocks in a fast feedback channel by using a first mapping pattern and to a second set of resource blocks in the fast feedback channel by using a second mapping pattern;
• and
• transmitting the sequence mapped to a plurality of sets of resource blocks,
• wherein the sequence is mapped to each of the plurality of sets of resource blocks, and
• wherein each element of the sequence is mapped to each resource block,
• wherein a mapping order of elements of the sequence in the first mapping pattern is different from a mapping order of elements of the sequence in the second mapping pattern,
• wherein the first set of resource blocks and second set of resource blocks have a predetermined same number of resource blocks each other, and
• wherein the first set of resource blocks is differently located from the second set of resource block in the fast feedback channel.
