论文摘要
LTE许可的辅助访问（LAA）网络已开始在美国的未经许可的5 GHz频段中广泛部署在美国的主要大都市地区，这些频段也已有Wi-Fi的密集部署。共存方案的各个方面引起了这些部署的产生，被认为是大量的学术和行业研究。但是，关于这些共存网络在实践中如何行事的数据和研究很少。 Wi-Fi和Laa之间公平共存的问题已从理论问题转变为现实。最近的LAA部署推出提供了一个机会，可以收集有关这些网络运行的数据，并在当地研究共处问题。在本文中，我们描述了在芝加哥的多个地区使用自定义应用程序和现成的工具进行了多个月的测量活动的第一个结果，主要运营商一直在扩大LAA部署。测量结果表明，在密集的城市环境中，LAA和Wi-Fi之间的共存，这两个系统汇总了多个渠道，仍然是一个充满挑战的问题，需要进一步研究。
LTE-Licensed Assisted Access (LAA) networks are beginning to be deployed widely in major metropolitan areas in the US in the unlicensed 5 GHz bands, which have existing dense deployments of Wi-Fi as well. Various aspects of the coexistence scenarios such deployments give rise to have been considered ina vast body of academic and industry research. However, there is very little data and research on how these coexisting networks will behave in practice. The question of fair coexistence between Wi-Fi and LAA has moved from a theoretical question to reality. The recent roll-out of LAA deployments provides an opportunity to collect data on the operation of these networks as well as studying coexistence issues on the ground. In this paper we describe the first results of a measurement campaign conducted over many months, using custom apps as well as off-the-shelf tools, in several areas of Chicago where the major carriers have been expanding LAA deployments. The measurements reveal that coexistence between LAA and Wi-Fi in dense, urban environments where both systems aggregate multiple channels, continues to be a challenging problem that requires further research.
