In order to achieve high transfer reliability, a mechanism called automatic repeat quest (ARQ) was applied in wireless communication system. The mechanism brings the complexity of storage management in the sender even though it can make the data transforming more reliability and flexible. The scheduling debris was thorough analyzed based on the research on the relationship between ARQ mechanism, and packets scheduling. The birth-death and size model was built for scheduling debris. In addition, a scheduling debris avoiding mechanism was designed using the information of resource prediction to reduce the number of scheduling debris. A simulation scenes based on LTE (Long Term Evolution) was designed to evaluate the mathematics model and scheduling avoiding mechanism. The simulations results show that the model can well describe the scheduling debris and the scheduling debris avoiding mechanism can efficient reduce the packet generating.
