Apparatus and method for selecting best beam in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, configuration information including:
• information on resources in which one or more reference signals are transmitted, and
• information on an index for indicating a synchronization signal among one or more synchronization signals;
• transmitting, to the terminal, one or more reference signals based on the configuration information;
• and
• receiving, from the terminal, feedback information indicating an index of a reference signal among the one or more reference signals.

A terminal in a wireless communication system, comprising:

• at least one transceiver;
• and
• at least one processor configured to:
• receive, from a base station via the at least one transceiver, configuration information including:
• information on resources in which one or more reference signals are transmitted, and
• information on an index for indicating a synchronization signal among one or more synchronization signals;
• receive, from the base station via the at least one transceiver, one or more reference signals based on the configuration information;
• and
• transmit, to the base station via the at least one transceiver, feedback information indicating an index of a reference signal among the one or more reference signals.
