【摘要】 直接序列码分多址接入(DS-CDMA)已成为下一代无线蜂窝网络中提供高速多媒体业务的主要接入技术。TD-SCDMA蜂窝网络与时分多址(TDMA)/频分多址(FDMA)网络有很大差别,前者独有的特征可用于提高系统容量。文中描述了DS-CDMA蜂窝网络中的资源管理,指出在资源管理机制设计中面临的主要挑战,讨论了资源管理的关键问题,包括拥塞控制、速率和功率控制、蜂窝规划和呼叫接入控制。更多还原

【Abstract】 Direct sequence code-division multiple access has been the predominant access technology to provide high-speed multimedia services in next-generation wireless cellular networks. The DS-CDMA cellular network significantly differentiates itself from the traditional narrowband TDMA / FDMA system, in which great capacity gain can be explored by taking advantage of its unique characteristics. This article addresses resource management in DS-CDMA cellular networks and discusses the main challenges in the design of resource management schemes. We then examine several critical issues within the scope of resource management, including congestion control, rate and power control, and cell planning, with emphasis on call admission control.更多还原
