1. A method performed by a terminal for receiving a reference signal (RS) in a wireless communication system, the method comprising:
receiving, from a base station, a control message including first information indicating that a first channel and a second channel share an [ a first ] RS on the first channel [ , ] and second information configuring a [ first ] transmission mode for the first channel and [ a second transmission mode for ] the second channel;
receiving the [ first ] RS on the first channel;
identifying whether a [ the ] first transmission mode for the first channel and a [ the ] second transmission mode for the second channel support a sharing of the received [ first ] RS [ received on the first channel] ; and
receiving, in case that the first transmission mode [ for the first channel ] and the second transmission mode [ for the second channel ] support the sharing of the received [ first ] RS [ received on the first channel] , data on the second channel based on the [ first ] RS received on the first channel [ ; and
receiving, in case that the first transmission mode for the first channel and the second transmission mode for the second channel do not support the sharing of the first RS received on the first channel, the data on the second channel based on a second RS received on the second channel] .
