摘　　要：在WCDMA系统中设计分组调度算法不仅需要关注信道条件,还需要关注功率问题。由此,提出了基于功率指数和名义容量概念的WCDMA系统区分业务类型码分通用处理器共享调度算法(SD-CDGPS),通过引入业务区分模型、动态名义容量分配模型和补偿模型,在提供时延上限的同时确保了各类型业务流之间的短期和长期公平性,并有较高的系统吞吐量。In order to design scheduling algorithm in CDMA systems, it＇s necessary to take channel condition and power of the link into consideration. Based on the concept of power index and nominal capacity, a modified code division generalized processor sharing-based scheduling （CDGPS） scheme with the generic name services differentiated CDGPS （SD-CDGPS） is proposed, which involves services differentiation model, nominal capacity dynamic allocation model and compensation model. The simulation results show that bounded delay can be provisioned for delay sensitive services and short-term and long-term fairness can be assured by using the SD-CDGPS schemes.
