APPARATUS AND METHOD FOR SUPPORTING HYBRID AUTOMATIC REPEAT REQUEST IN A BROADBAND WIRELESS COMMUNICATION SYSTME

摘要

PURPOSE: An apparatus and a method for supporting hybrid automatic repeat request in a broadband wireless communication system are provided to enable a receiving unit to obtain an additional frequency by allowing a transmitting unit to transmit packets through different kinds of FAs during initial transmission and retransmission when performing a CC method. CONSTITUTION: A method for supporting hybrid automatic repeat request in a broadband wireless communication system comprises the steps of: splitting one encoded packet into plural pieces(501); transmitting the plural split pieces through plural FAs(503); determining FAs that are supposed to be used when re-transmitting the encoded packet pieces if NACK(Non-ACKnowledge) is received for the encoded packet(505); and retransmitting the encoded pieces of the encoded packets through the determined FAs(507).
