In recent years, multimedia services are developing rapidly in mobile communication systems. The multimedia services consist of many kinds of data which have different characteristics. To enable these services to be provided, because of large amount of data, there needs more effective utilization of radio resources in limited bandwidth. One of the solutions is making an effective DLC (Data Link Control) for QoS (Quality of Service) assurance. In this paper, we propose a structure of radio protocol and the DLC protocol layer which consists of hierarchical component based functional entities and an effective radio link control. The DLC is operated by the state of current traffic volume. For the efficiency of radio resource utilization, different adequate components will be taken by the current traffic state. Especially fraction based data transmission buffer control method with ARQ scheme, which is dynamic parameter change scheme, based on logical channel priority and DLC state for the QoS assurance in Wireless LAN system.
