$\textit{Scheduling scheme and non-scheduling scheme}$ are representative multiplexing schemes for cellular downlink. The scheduling scheme allocates radio resource to a few scheduled mobile stations while the non-scheduling scheme supports all admitted mobile stations. Therefore, the scheduling scheme provides intermittent service with large amount of radio resource and the non-scheduling scheme serves the mobile stations continuously with relatively small amount of radio resource. According to the different feature of each scheme, it is desirable to accommodate non-real time, high data rates in the scheduling system while the non-scheduling system can support low/medium rate data services and real-time services with short delays and small delay variations. Since the total system capacity is considered as one of important performance metrics in designing future wireless communication systems, the scheduling scheme is considered as a good candidate. However, there are various types of services, such as VoIP, real-time video, and data services. Some services generate real-time and medium/low rate traffic, while other services generate bursty and high rate traffic. QoS metrics, such as delay and delay variation can be important performance metrics for evaluating the performance of the scheduling systems. In the viewpoint of QoS parameters, the scheduling system cannot be a sole resource allocation scheme for optimal communication systems. In this dissertation, we propose a hybrid scheduling system (HSS) which combines the scheduling and non-scheduling schemes to provide QoS guaranteed services and maximize the system capacity simultaneously. The proposed HSS combines the different multiplexing schemes using $\textit{operation mode classifier}$ and $\textit{bandwidth manager}$. According to a design strategy for the operation mode classifier and the bandwidth manager, various versions of HSSs can be implemented. We implement three different types of HSSs : HS...
