A method for generating a subframe including resource distribution information is disclosed. The method for generating a subframe includes arranging resource allocation information in a subframe by sequentially allocating a localized permutation and a distributed permutation, and arranging a subframe control header including a resource unit index in a predetermined location by a system parameter, wherein the resource unit index indicates a frequency resource location of the resource allocation information. When both the localized permutation and the distributed permutation are used, a resource distribution method is transmitted to a user equipment. Therefore, an effect of the distributed permutation can be maximized without a great influence on the performance of the localized permutation, and a problem of decoding failure or latency can be prevented.

A mobile station apparatus for transmitting feedback information in a wireless communication system and method thereof are disclosed. According to the present invention, feedback information is transmitted by a mobile station in a wireless communication system. The present invention includes receiving an allocation of a specific frequency partition from a base station by a fractional frequency reuse (FFR), generating a prescribed type feedback information on the specific frequency partition by measuring a channel quality of the specific frequency partition, and transmitting the feedback information on the specific frequency partition to the base station. Preferably, the mobile station can transmit feedback information on a frequency partition unallocated by the base station based on the received feedback request information. Accordingly, feedback overhead can be decreased in feedback transmission.
