寬帶無(wú)線城域網(wǎng)是當(dāng)今無(wú)線通信領(lǐng)域中的一個(gè)熱點(diǎn)，而其中的資源調(diào)度策略直接關(guān)系到
系統(tǒng)性能的優(yōu)劣。本文針對(duì)IEEE802.16 標(biāo)準(zhǔn)下的寬帶無(wú)線接入系統(tǒng)設(shè)計(jì)了一套能夠保證用戶QoS 的資源調(diào)度和分配方案，該方案由接納控制方案、請(qǐng)求機(jī)會(huì)分配方案及帶寬分配方案三部分組成，它的雙層調(diào)度機(jī)制能夠針對(duì)不同QoS 等級(jí)的業(yè)務(wù)提供不同的調(diào)度方案，滿足用戶的QoS 要求。

The Design and Realization of an Integrated Resource Scheduling Scheme for WMAN
(Tsinghua University wireless and mobile communication technology research center) Zhang Jin, Su Xin Abstract Broadband Wireless Metropolitan Area Network (MAN) is a booming branch in the area of wireless communication. The design of the resource allocation and scheduling scheme of the system is in close relation with the whole system performance. A novel resource allocation scheme which can guarantee the QoS is proposed in this paper. The scheme includes the connection access control, the bandwidth request timeslot allocation and data bandwidth allocation. The two-layer scheduling architecture of the scheme can provide different scheduling strategy for services with various QoS grade to guarantee their QoS.
