1. A method performed by a terminal in a mobile communication system, the method comprising:
receiving, from a base station, first measurement configuration information;
measuring first reference signals for obtaining reference signal received power (RSRP) information based on the first measurement configuration information, the first reference signals being associated with a cell serving the terminal;
transmitting, to the base station, the RSRP information;
receiving, from the base station, second measurement configuration information including a set of second reference signals to be measured, the second reference signals being associated with the cell serving the terminal and being determined based on the RSRP information;
measuring the second reference signals for obtaining channel state information (CSI) based on the second measurement configuration information; and
transmitting, to the base station, the CSI.
