Abstract: The present invention relates to an uplink framing method and apparatus in a mobile communication system. After a mobile terminal and a base station are connected to each other in a wireless manner, the base station allocates an uplink radio resource to a medium access control (MAC) layer of the mobile terminal, and then scheduling is performed for each connection in a buffer. Next, a packet data unit (PDU) is generated to satisfy the uplink time constraint and then transmitted to the base station. Therefore, hardware implementation complexity can be minimized in a mobile communication system that should support fast data transmission, and at the same time, a required uplink framing time can be minimized in a system that supports a short frame period.

Abstract: The present invention relates to a protocol data unit (PDU) reordering method in a wireless communication system. The terminal maintains the number of bytes of PDUs stored in the buffer for reordering PDUs received in a sequence that is changed due to HARQ error correction to thereby prevent overflow of the reordering buffer. When the HARQ function unit transmits a PDU received at the radio access control RAS (S101), the PDU reordering unit of the access terminal sets a current frame number as an arrival frame number of the received PDU (S102). When a current frame number is stored as an arrival frame number of a received frame, the PDU reordering unit compares a sequence number (SN) of a received PDU with a sequence number of a PDU that is about to be reordered (S 103). If the PDU has already been reordered, the received PDU is discarded (S 104).
