摘要： 针对可变速率的无线数据网络，提出了一种基于效用函数的资源管理策略。该策略兼顾了数据业务对吞吐量和速率波动的要求，并且综合考虑了速率分配和功率控制对系统性能的影响。仿真结果显示，该策略能够有效地抑制终端的传输速率波动;在信道环境较差时，改进后的算法可以进一步提高系统的性能。
关键词: 效用函数，资源管理，时帧占用，速率分配，功率控制
Abstract: A utility-based resource management strategy in wireless data network was proposed in this paper. The strutegy achieves a balance between throughput and rate oscillation of data service and takes into account the impact of both rate and power on the system performance. Numerical results show a low oscillation of rate and an efficient improvement of the system performance in poor channel condition.
Key words: Utility function, Resource management, Time frame occupancy, Rate allocation, Power control
