摘要:

为更好地利用系统资源,对调度控制和专用速率控制等媒体接入控制(MAC)技术进行了分析比较,并结合它们的特点提出了一种新的混合媒体接入控制技术. 按照3GPP2规定的仿真方法论,进行了基于CDMA2000 1x EVDVRelD的模拟动态仿真分析. 结果表明混合策略可以提高系统稳定性,减少时延,提高吞吐量,更好地满足各种服务质量(QoS)业务的需求.

Abstract:

The media access control (MAC) mechanisms such as the scheduling and rate control were analyzed. A new combined MAC scheme was proposed based on a comparison of the two approaches. A CDMA2000 1x EVDVRelD system was simulated based on the methodology specified in 3GPP2. The simulation results show that the proposed scheme improves the system stability while increases the throughput and resource utilization of the system. The transmission delay is also reduced so that the quality of service (QoS) requirements of various services can be better satisfied.

Key words: media access control technique, scheduling, rate control, proportional fair, throughput, delay, system stability
