Apparatus and method for supporting hybrid automatic repeat request in a broadband wireless communication system

摘要

A broadband wireless communication system using a plurality of Frequency Allocations (FAs) is provided. A method for packet transmission of a packet of a transmitting end includes dividing one encoded packet into a plurality of parts, mapping a plurality the plurality of parts of the packet to the FAs through the plurality of different FAs transmission, when a re-transmission request is received, re-mapping the plurality of parts of the packet to the FAs such that at least one of the at least one of the plurality of parts is re-mapped to an FA that is different than an FA previously mapped thereto. Retransmitting the encoded packet by at least one of a number of subunits.
