Description

一种终端载波聚合测试的装置
技术领域
本发明涉及第四代移动通信系统领域，特别是涉及一种终端载波聚合测 试的装置。
背景技术
当前随着移动通信的快速发展， 用户通信的信息量越来越大， 信号速率 不断增高下， 传输带宽越来越宽。 为此第四代移动通信系统釆用了关键技术 载波聚合， 对应此技术， 各终端厂家有不同的调制解调方案。 如何精确有效 测试、验证终端产品质量变得越来越复杂。例如： WCDMA ( Wideband Code Division Multiple Access,宽带码分多址）釆用关键技术 DC-HSUPA( Dual Cell - High Speed Uplink Packet Access, 双载波高速上行分组接入 ) , 虽然应用了 双载波技术， 由于其物理层及其调度等差异， 测试方法完全不同。 具体见其 终端一致性测试标准 TS34.121-1 ( V10.4.0 2012-09 ) 。
载波聚合技术， 在接入网上行或下行最多有 5个载波， 当前标准对 2个 载波进行了定义。 其中上行、 下行信号均有唯——个主组分载波（Primary Component Carrier, 简称 PCC, 又称主成员载波） ， 辅组分载波（ Secondary Component Carrier, SCC, 又称次成员载波）可多个或没有。 载波聚合分为 两大类， 同带载波聚合和异带载波聚合， 其中， 同带载波聚合又分为同带连 续载波聚合及同带非连续载波聚合。
对于终端应用载波聚合 ( CA )测试， 考虑用户终端 （简称 UE或终端） 釆用不同天线接口及信号映射， 国际标准中已定义分成为三种类型：
第一种为每个组分载波（PCC、 SCC )使用独立的天线连接器。 UE可选 择使用一个宽带天线， 仅用于 CA信号分集接收， 以提高接收灵敏度。
第二种为在天线应用上， 上行传输的载波聚合信号使用同一个天线连接 器。
第三种为在天线应用上，上行传输的载波聚合信号使用不同天线连接器。 相关终端 CA 的测试连接及方法等， 在 3gpp RAN5 #57 次会议上 R5-125187等提案有定义。
针对通过的 R5-125187提案， 针对上述第一种终端， 分别直接接入天线 口 PCC信号或 SCC信号， 而现实生活中信号在空中传播是混合在一起的， 这样的话也忽略了终端鉴别不同信号的基本能力。 其二， 针对上述第二种及 第三种终端， 对称设置的功分器、 合路器实际工作中性能很难做到一致， 容 易引起测量误差。 发明内容
