摘要:

将适用于单载波系统的具有最小和最大速率约束的梯度调度算法扩展到多载波系统,提出一种基于效用函数的多载波梯度调度算法。该算法可以作为后3代无线通信系统的多用户调度策略。理论分析和仿真结果表明该算法具有较好的性能和较低的算法复杂度,可以为数据业务提供软服务质量(QoS)保证。

Abstract:

Aiming at multi-carrier system, a utility-based radio resource scheduling method, named as Multi-carrier gradient scheduling algorithm with minimum/maximum rate constraints (GMR) is proposed. As an extension of GMR, it can be used in beyond tree generation (3G) wireless communication system for multiuser scheduling. Analysis and simulation results show that the algorithm can provide soft quality of service (QoS) guarantee with good performance and low complexity.

Key words: beyond three generation wireless system, multi-carrier system, scheduling algorithm, utility function, soft quality of service
