Method and apparatus for transmitting and receiving reference signal in wireless communication system

A method and an apparatus for transmitting or receiving a reference signal in a wireless communication system are disclosed. According to the embodiment of the invention, method by which a terminal receives a tracking reference signal (TRS) in a wireless communication system, comprising the steps of: receiving from a network N (N is an integer greater than or equal to 1) comprising indications for being indicated for its activation a control element including first information of an identifier of a cell and second information of a field related to a TRS corresponding to each of the N cells; and receiving one or more TRSs for one or more cells among the N cells, wherein the size of the control element may be based on the N value. 公开了一种用于在无线通信系统中发送或接收参考信号的方法和装置。根据本公开的实施例，通过其终端在无线通信系统中接收跟踪参考信号(TRS)的方法包括以下步骤：从网络接收包括指示用于针对其激活被指示的N个(N是大于或等于1的整数)小区的标识符的第一信息以及包括与对应于N个小区的每个的TRS相关的字段的第二信息的控制元素；以及接收用于N个小区之中的一个或多个小区的一个或多个TRS，其中控制元素的大小可以基于N值。
