LTE-AdvancedPro射频一致性测试系统中Massive CA模块设计

Design of massive carrier aggregation module in LTE-AdvancedPro radio frequency conformance testing system

随着第三代合作伙伴计划(3GPP)标准的不断演进,测试已成为移动通信产业链中独立的核心环节,而核心模块的设计直接影响到通信测试系统对新特性的支持能力。载波聚合(CA)技术在3GPP R10标准中被引入,在R13版本中进行了增强,其支持最大载波数增加为32个,可实现超过20Gbps的峰值速率,这给通信测试带来了极大的挑战。因为目前还没有支持Cat17的商用终端,所以国内外通信测试厂商也没有将其列为研究重点。介绍了一种LTE-AdvancedPro射频一致性测试系统中Massive CA模块的设计方法,通过对Massive CA技术特点进行分析,给出了Massive CA模块的架构及信令设计思路及方法,为3GPP R13标准中Massive CA新特性的测试验证提供了新方法。

With the continuous evolution of 3GPP standards,testing has become an independent core link in the mobile communication industry chain,and the design of core modules directly affects the support ability of the communication test system for new features.Carrier aggregation technology was introduced into the 3GPP R10 standard and enhanced in the R13 version.The maximum number of carriers supported by carrier aggregation technology was increased to 32,which can achieve a peak rate of more than 20 Gbps,which poses a great challenge to communication testing.Because there is no commercial terminal supporting Cat 17 at present,the domestic and foreign communication test manufacturers have not listed it as the research focus.This paper introduces a design method of Massive CA module in LTE-AdvancedPro radio frequency conformance testing system.By analyzing the technical characteristics of Massive CA,the architecture of Massive CA module and the design idea and method of signaling are given,which provides a new method for testing and verifying the new characteristics of Massive CA in 3GPP R13 standard.
