摘要:

对IEEE 802.16e的主动授权、实时、扩展的实时、非实时、尽力而为等业务提出了不同的分组调度算法,这些算法充分考虑了小区间干扰、业务状态、信道的快慢衰变化等。仿真结果显示,联合考虑小区间干扰和业务分类及其信道状况的分组调度算法性能显著提高.

关键词: 宽带无线接入;小区间干扰;分组调度, 服务质量

Abstract:

Considering inter-cell interferences, service status, and channel conditions, the wireless packet scheduling algorithms are presented, in which the unsolicited grant service (UGS), real time polling service (rtPS), extended rtPS(ertPS), non real time polling service (nrtPS), and best effort (BE) services are supported. Numerical results reveal that the proposed scheduling algorithm improves the overall network throughput.

Key words: broadband wireless access;inter-cell interference, packet scheduling, quality of services
