Abstract
A method of acquiring information on a resource region for transmitting PHICH and a method of receiving PDCCH using the same are disclosed. The resource region for transmitting the PHICH can be specified by first information corresponding to the per-subframe PHICH number and second information corresponding to a duration of the PHICH within the subframe. The first information can be specified into a form resulting from multiplying a predetermined basic number by a specific constant. And, the specific constant can be transmitted via PBCH. Moreover, the second information can be acquired from the PBCH as well.
