摘要

分析了WiMAX下行链路数据突发间的时隙分配方法。分析的结果区分了已知决策的缺点，形成了对数据突发间槽分配问题的基本要求。提出了IEEE 802.16下行链路中插槽分配和数据突发调度的数学模型。所提出的模型侧重于在每个用户站的下行链路中形成一个数据包，以使通过所使用的频率通信信道发送的开销信息的数量最小化。分析了由用户站所需的传输速率组成一个数据包的时隙数量与调制和编码方案类型的关系。

Slot allocation model and data burst scheduling in downlink WiMAX technology

Current approaches to slot allocation among data bursts in downlink of WiMAX technology were analyzed. As a result of the completed analysis drawbacks of known decisions were distinguished and basic requirements to the slot allocation problem among data bursts were formed. A mathematical model of slots allocation and data burst scheduling in the downlink of IEEE 802.16 standard is proposed. The proposed model is focused on the formation of one data packet in downlink for each subscriber station that minimizes the number of overhead information sent over the used frequency communication channel. The dependence of the amount of slots, forming one data packet from required transmission rate of a subscriber station and type of modulation and coding scheme were analyzed.
