4. A method performed by a base station in a wireless communication system, the method comprising:
receiving, from a terminal, beam switching capability information of the terminal;
determining whether the terminal is capable of beam switching within resource regions, used for transmitting a reference signal based on the beam switching capability information; and
transmitting, to the terminal, configuration information on the reference signal based on a result of the determination,

receive, via the transceiver from a terminal, beam switching capability information of the terminal,
determine whether the terminal is capable of beam switching within resource regions, used for transmitting a reference signal, based on the beam switching capability information, and
transmit, via the transceiver to the terminal, configuration information on the reference signal based on a result of the determination,
wherein, in case that the terminal is not capable of the beam switching within the resource regions, the configuration information instructs the terminal to measure the reference signal for a first subset of the resource regions and the reference signal for a second subset of the resource regions, and
wherein the first subset is included in a first measurement period and the second subset is included in a second measurement period which is next to the first measurement period.
11. The base station of claim 10 , wherein the controller is configured to control to
