摘要

基于IEEE 802.16e的宽带无线接入网是提供宽带服务最有前途的解决方案之一。针对非实时轮询服务和最佳努力服务，提出了一种高效的带宽请求方案。为了减少对带宽请求的延迟，该方案采用BR码表示移动站所需的UIUC和子信道数。因此，它可以省略带宽请求消息的传输过程。我们进行数学分析。结果表明，与IEEE 802.16e方案相比，该方案能够有效降低时延和信令开销。

A Fast Bandwidth Request Scheme in IEEE 802.16e OFDMA/TDD Systems

Broadband wireless access network based on the IEEE 802.16e is one of the most promising solutions to provide broadband services. This paper proposes an efficient bandwidth request scheme for non real-time polling service and best effort service. In order to reduce the delay for bandwidth request, the proposed scheme makes BR code indicate the UIUC and the number of subchannels required by mobile station. Accordingly, it can omit the transmission procedure of bandwidth request message. We perform the mathematical analysis. The results show that the proposed scheme can reduce the delay and the signaling overhead compared to the IEEE 802.16e scheme.
