Abstract: An apparatus and method for scrambling in a wireless communication system are provided. The apparatus includes a selector, a plurality of scramblers, and a plurality of modulators. The selector selects a scrambling scheme to be applied to a transmission bit stream according to a modulation scheme to be applied to the transmission bit stream. The plurality of scramblers scramble the transmission bit stream according to a scrambling scheme corresponding to each of a plurality of modulation schemes. The plurality of modulators modulate the scrambled transmission bit stream according to the plurality of modulation schemes.

Abstract: An apparatus and a method for Hybrid Automatic Repeat reQuest (HARQ) in a wireless communication system are provided. A receiver includes a Media Access Control (MAC) layer part for error-checking each MAC Packet Data Units (PDUs) extracted from a physical layer burst, and generating HARQ combination control information according to a result of the error check; a receiving part for receiving a retransmit burst; and a combiner for selecting one or more Forward Error Correction (FEC) blocks from the retransmit burst according to the HARQ combination control information, and HARQ-combining the selected one or more FEC blocks.
