基于载波聚合技术的FDD-LTE网络设计方案

摘要

为满足LTE高速率的要求和频谱的限制,提出了载波聚合技术.对载波聚合技术特点、类型和应用场景进行分析,通过一个Band 3(1.8 GHz)+Band 3(1.8 GHz)带内连续载波的组合设计方案案例,网络环境选取可用的测试点和测试卡对10 M频段与FDD的20 M频段进行载波聚合,采用工具进行验证,可得小区下载速率达到理论峰值,测试效果明显.%The requirement of LTE high speed rate and the limit of frequency spectrum , the carrier aggregation technique is proposed. Analysing the characteristics and types and application scenarios of the carrier aggregation technology,and a case of Band 3 (1.8GHz)+Band 3 (1.8 GHz) combined design with continuous carrier is taken which Network environment to select the available test points and test card to the 10M band and 20M FDD band carrier aggregation. Using tools to verify , the rate of residential area to reach the peak value is got ,and the test results are clear.
