QUEUE POOL STRUCTURE OF A COMMUNICATION SYSTEM, PARTICULARLY FOR MINIMIZING A PACKET LOSS IN A 1XEVDV SOFTER CELL SWITCHING

摘要

PURPOSE: A queue pool structure of a communication system is provided to maximize system performance by effectively using a memory. CONSTITUTION: An MAC packet buffer unit(10) includes a plurality of MAC packet buffers for storing an MAC packet. A free queue unit(20) includes a plurality of free queues one-to-one linked to the plurality of MAC packet buffers, stores received MAC packets in the MAC packet buffer unit(10). A user identification queue unit stores the MAC packet information transmitted from the free queue unit(20). The user identification queue includes an RLP queue storing the MAC packet information and a hybrid automatic re-transmission request channel identifier queue.
