将LTE-U嵌入Wi-Fi频段以提高频谱效率
Embedding LTE-U within Wi-Fi Bands for Spectrum Efficiency Improvement
摘要：
受日益增长的频谱短缺的驱动，最近已经提出了非授权频谱中的长期演进（LTE-U）作为通过将LTE协议扩展到非授权频谱来为移动用户提供更好的性能和体验的新范例。在本文中，我们首先对LTE-U技术进行了全面的概述，并讨论了它所面临的实际挑战。总结了现有的LTE-U工作模式，分析了LTE-U与Wi-Fi媒体接入控制协议共存的几种方式。我们进一步提出了一种新型的超级接入点（HAP），它集成了LTE小型小区基站和商用Wi-Fi AP的功能，供蜂窝网络运营商部署。我们提出的嵌入在Wi-Fi协议中的LTE-U接入对未授权Wi-Fi节点是无中断的，并且展示了作为未授权频带中的无缝和新颖的LTE和Wi-Fi共存技术的性能优势。我们提供的结果来证明这种新的LTE-U建议的性能优势。
英文摘要：
Driven by growing spectrum shortage, Long-term Evolution in unlicensed spectrum (LTE-U) has recently been proposed as a new paradigm to deliver better performance and experience for mobile users by extending the LTE protocol to unlicensed spectrum. In the paper, we first present a comprehensive overview of the LTE-U technology, and discuss the practical challenges it faces. We summarize the existing LTE-U operation modes and analyze several means for LTE-U coexistence with Wi-Fi medium access control protocols. We further propose a novel hyper access-point (HAP) that integrates the functionalities of LTE small cell base station and commercial Wi-Fi AP for deployment by cellular network operators. Our proposed LTE-U access embedding within the Wi-Fi protocol is non-disruptive to unlicensed Wi-Fi nodes and demonstrates performance benefits as a seamless and novel LTE and Wi-Fi coexistence technology in unlicensed band. We provide results to demonstrate the performances advantage of this novel LTE-U proposal.
