Abstract: PURPOSE: A device and a method for reducing the size of an encoding overhead are provided to reduce the size of the encoding overhead using ROC and PDU_SN instead of PN added at each MPDU(MAC Protocol Data Unit). CONSTITUTION: An MPDU encoding device of a wireless access system includes a transmission data processor(610) and a message generator(612). The transmission data processor generates an uncoded MPDU. A message generator confirms a sequence number for counting the number of the MPDU transmitted in the generation of the uncoded MPDU.

Abstract: PURPOSE: A device and a method for generating data for controlling an error in a wireless communication system are provided to reduce a wasted resource according to the size of MPDU(MAC Protocol Data Unit) in a physical layer by adding the MSDU(MAC Service Data Unit) information to the MPDU. CONSTITUTION: A MAC layer reconstructs at least one MAC layer service data unit received from an upper layer according to the scheduling information of the MAC layer. The MAC layer generates a data part of at least one MAC layer protocol data unit. The control information includes the information of at least one MSDU comprising the data part of the MPDU. An MPDU payload is generated by adding the control information to the data part of the MPDU. A common MAC header including the connection identifier information and the length information of the MPDU payload is added to each MPDU payload. An FPI(Fragmentation and Packing Indicator) includes information about a fixed field(300) and a variable field(310). The fixed field includes a sequence number, a FC field, and a LAST field. The variable field includes an LEN field and the LAST field.
