本发明涉及通信技术领域，特别是涉及一种识别载波的终端、网络设备及其方法。

目前，标准定义的载波包括Legacy（传统）载波和NCT（New Carrier Type，新载波类型）载波，NCT载波又进一步包括Non-standalone（非独立） NCT载波和Standalone（独立的） NCT载波。其中，Non-standalone NCT载波不能单独操作，必须与Legacy载波或者Standalone NCT载波进行载波聚合（Carrier Aggregation，CA）处理，Standalone NCT载波是对Non-standalone NCT载波的进一步增加，支持广播机制来获取系统信息和终端（User Equipment，UE）的移动性。
现有技术中，UE可以根据PSS（Primary Synchronization Signal，主同步信号）和SSS（Secondary Synchronization Signal，辅同步信号）的相对位置信息来识别载波的类型。例如：在FDD（Frequency Division Duplex，频分复用）系统中，Legacy载波的PSS位于第0子帧和第5子帧的最后一个OFDM（Orthogonal Frequency Division Multiplexing，正交频分复用）符号上，而SSS位于第0子帧和第5子帧的倒数第二个OFDM符号上。通过改变PSS和SSS的相对位置，例如：PSS和SSS间隔一个OFDM符号，以使UE能够识别Legacy载波和NCT载波。虽然UE可以根据同步信号的检测结果来区分Legacy载波和NCT载波，但是无法进一步区分Non-standalone NCT载波和Standalone NCT载波。
