1. A method of distributing and performing reordering of protocol data units (PDUs) and reassembly of service data units (SDUs) in a radio link control (RLC) layer over many transmission time intervals (TTIs), comprising:

  • recognizing, by an RLC entity of a reception side, a TTI start time;

    initializing a count of the number of PDUs to be processed in a TTI;

    processing a reordering timer by determining whether the reordering timer has expired, and performing a procedure of reassembling RLC SDUs and transmitting the reassembled RLC SDUs to an upper layer and updating the reordering timer when the reordering timer has expired;

    processing reception by performing the procedure and updating the reordering timer when an RLC PDU received from a lower layer is an RLC PDU which should be received by retransmission from a transmission side before reordering timer expiration; and

    processing transmission by processing RLC SDUs received from the upper layer,wherein the procedure limits the number of RLC PDUs to be processed within a TTI using the count of the number of PDUs to be processed within the TTI.
