摘要
通过对LTE FDD覆盖增强关键技术的研究和实际外场试验测试,提出了LTE FDD多天线技术、上行IRC技术和上行功控技术在LTE FDD覆盖中的综合应用解决方案。认为通过上行8天线的方式,可以增加6 dB以上的覆盖增益;通过IRC等覆盖增强技术能有效地消除小区间的干扰。这些技术的综合运用,可以有效提高LTE网络的覆盖质量,提高用户体验。
This paper describes an LTE TDD coverage comprehensive application solution of LTE FDD multiantenna technology, uplink interference rejection combining (IRC) technology, and uplink power control technology, 6 dB coverage gains can be increased by LTE FDD uplink 8 antennas, and cell interference can be reduced by using IRC technology. The intergrated use of these technologies can improve the quality of LTE network coverage and improve user experience.
