Abstract

This paper presents frameworks for performing radio resource allocation in Orthogonal Frequency-Division Multiple-Access (OFDMA) networks. The schemes exploit the system interference dynamics to achieve improved system throughput. One of the schemes, the interference-aware is suitable for the conventional (non-relay) network, while the second scheme is conceived for relay-based networks. The two schemes exploit the interference situation. The numerical results show a significant improvement in throughput through the proposed schemes. Our investigation provides insights on the potential performance improvements from a two-hop relaying scheme with simple distributed resource management policies. The results demonstrate that although researchers may be looking for advanced and complex radio resource management (RRM) scheme for future broadband wireless networks, some simple but moderately interferencesmart schemes are enough to provide sufficiently good results.
基于ofdma的无线网络干扰感知无线电资源分配技术
本文提出了在正交频分多址(OFDMA)网络中进行无线电资源分配的框架。这些方案利用系统的干扰动力学来提高系统吞吐量。其中干扰感知方案适用于传统(非中继)网络,而干扰感知方案适用于基于中继的网络。这两种方案利用了干扰情况。数值结果表明,所提出的方案显著提高了吞吐量。我们的调查提供了关于使用简单的分布式资源管理策略的两跳中继方案的潜在性能改进的见解。结果表明,尽管研究人员可能正在为未来的宽带无线网络寻找先进而复杂的无线电资源管理(RRM)方案,但一些简单但适度干扰智能的方案足以提供足够好的结果。
