通过无线电之间的机会性频谱共享来提高频谱效率是无线通信领域的最新研究课题。根据SPTF关于未使用频段的报告，DARPA正在研究在其XG通信计划中利用这些未使用频段的机会。本文给出了在无线系统中使用XG方法的一些选择，例如ieee802.11或无线局域网（WLAN）。已经确定了不同的基于策略的XG参数和各自的802.11可调参数，并显示/分析了这些参数之间的映射。利用策略和系统一致性块以及传感器，描述了具有DARPA XG通信的802.11无线电系统的扩展结构模型。可以得出结论，适当地将XG策略映射到抽象行为，并根据策略控制无线电，可以增加频谱共享机会，从而提高频谱效率，例如系统的吞吐量。
Increasing the spectral efficiency by opportunistic spectrum sharing among radios is the very recent research topic in the field of wireless communication. According to the report of SPTF about unused spectrum bands, the DARPA is investigating on opportunistic use of these unused bands in its XG communication program. In this paper, some options to use XG approach for the wireless systems, for example, for IEEE 802.11 or wireless local area network (WLAN) are shown. Different policy based XG parameters and respective 802.11 tunable parameters have been determined and the mapping among those parameters has been shown/analyzed. An extended structural model of the 802.11 radio system with DARPA XG communication is depicted with the help of policy and system conformance blocks and sensor. It can be concluded that, proper mapping of XG policies to abstract behaviors and controlling the radio according to polices, could increase the spectrum sharing opportunities and hence the spectral efficiency, for example, the throughput of the system.
