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.

1. A method of receiving a Physical hybrid ARQ indicator channel (PHICH) signal by a user equipment (UE), the method comprising: receiving a physical broadcast channel (PBCH) signal from a base station, the PBCH signal comprising information related to a system bandwidth, first information related to a specific constant for PHICH allocation per subframe, and second information related to a duration of a PHICH per subframe;transmitting an uplink signal to the base station;determining a value by multiplying a basic number predetermined according to the system bandwidth by the specific constant;determining a specific resource region for receiving the PHICH signal based on the determined value and the duration of the PHICH; andreceiving the PHICH signal from the base station within the determined specific resource region. 2. The method of claim 1, wherein the specific constant comprises a positive integer. 3. A method of transmitting one or more physical hybrid ARQ indicator channel (PHICH) signals by a base station, the method comprising: transmitting a physical broadcast channel (PBCH) signal to one or more user equipment (UEs), the PBCH signal comprising information related to a system bandwidth, first information related to a specific constant for PHICH allocation per subframe, and second information related to a duration of a PHICH per subframe;receiving one or more uplink signals from the one or more UEs;determining a value by multiplying a basic number predetermined according to the system bandwidth by the specific constant;determining a specific resource region for transmitting the one or more PHICH signals based on the determined value and the duration of the PHICH; andtransmitting the one or more PHICH signals to the one or more UEs, in response to the one or more uplink signals, within the determined specific resource region. 4. The method of claim 3, wherein the specific constant comprises a positive integer.
