Abstract:
1. A method for generating data of a Media Access Control (MAC) layer in a wireless communication system, the method comprising: if Automatic Repeat reQuest (ARQ) feedback information is received, determining the occurrence of an error in at least one MAC Protocol Data Unit (MPDU) transmitted to a receive end; if the error occurs in the at least one MPDU, fragmenting an erroneous MPDU data portion into at least two sub blocks; generating at least one retransmission MPDU data portion comprising at least one of the sub blocks; adding control information to each retransmission MPDU data portion and generating at least one retransmission MPDU payload, the control information comprising MAC Service Data Unit (MSDU) information constituting each retransmission MPDU data portion; adding a General MAC Header (GMH) to each retransmission MPDU payload and generating at least one retransmission MPDU, the GMH comprising length information on the retransmission MPDU and Connection IDentifier (CID) information; and transmitting the retransmission MPDU to the receive end.
