Reference signal sharing method and device in mobile communication

Methods and apparatus related to reference signal sharing in mobile communications are described herein. An apparatus (e.g., a UE) receives a plurality of reference signals including a first set of reference signals and a second set of reference signals. The apparatus performs time or frequency tracking based on a plurality of reference signals. Alternatively, the apparatus generates a channel state information (CSI) report associated with a plurality of reference signals and transmits the CSI report to the network. According to the reference signal sharing method and device in mobile communication provided by the invention, partial or all reference signals transmitted by one system can be shared by another system, so that radio resources are effectively utilized. 描述了与移动通信中的参考信号共享有关的方法及装置。装置(例如，UE)接收包括第一组参考信号和第二组参考信号的多个参考信号。该装置基于多个参考信号执行时间或频率跟踪。或者，该装置生成与多个参考信号相关联的信道状态信息(CSI)报告并将该CSI报告发送到网络。根据本发明所提供的移动通信中的参考信号共享方法及装置，可以实现一个系统传输的部分或全部参考信号由另一系统共享，从而有效地利用无线电资源。
