Patent ID: 7729305

Claim:
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: determining, by the BS, segment indicator information for renumbering to be applied to subchannels in a Partial Usage of SubChannels (PUSC) interval, the segment indicator information being included in a Space Time Coding Zone Information Element (STC_ZONE_IE); transmitting, by the BS, the determined segment indicator information to the MS; receiving, by the MS, the segment indicator information transmitted from the BS; and performing, by the MS, a renumbering process on the PUSC subchannels using the received segment indicator information, wherein the segment indicator information includes a Pseudo Random Bit Sequence Identifier (PRBS_ID) indicating a single frequency network service, and wherein the PRBS_ID has a same value or a random value between BSs or sectors.
