System and method for providing services using the same frequency in a wireless communication system

A Base Station (BS) apparatus for performing communication with a Mobile Station (MS) in a wireless communication system, the BS apparatus comprising:

• a message generator for generating a downlink (DL) MAP message including a Pseudo Random Bit Sequence Identifier (PRBS_ID) for renumbering subchannels in a predetermined Partial Usage of SubChannels (PUSC) zone from among a plurality of PUSC zones included in a downlink (DL) frame, the PRBS_ID being included in a Space Time Coding Zone Information Element (STC_ZONE_IE) of the DL MAP message;
• and
• a transmitter for transmitting the DL MAP message via the DL frame.

A Mobile Station (MS) apparatus for performing communication with a Base Station (BS) in a wireless communication system, the MS apparatus comprising:

• a receiver for receiving a Pseudo Random Bit Sequence Identifier (PRBS_ID) within a Space Time Coding Zone Information Element (STC_ZONE_IE) of a downlink (DL) MAP message included in a DL frame from the BS;
• and
• a subchannel extractor for renumbering subchannels in a predetermined Partial Usage of SubChannels (PUSC) zone from among a plurality of PUSC zones included in the DL frame, using the PRBS_ID.

A method for performing communication between a Base Station (BS) and a Mobile Station (MS) in a Broadband Wireless Access (BWA) communication system, the method comprising:

• receiving, by the MS, a Pseudo Random Bit Sequence Identifier (PRBS_ID) within a Space Time Coding Zone Information Element (STC_ZONE_IE) of a DL MAP message included in a DL frame from the BS;
• and
• renumbering, by the MS, subchannels in a predetermining Partial Usage of SubChannels (PUSC) zone from among a plurality of PUSC zones included in the DL frame, using the PRBS_ID.
