Classification: CPC H | IPC H

Claim 0:
1. An operation method of a terminal in a communication system, the operation method comprising:
receiving first configuration information of one or more guard bands of an unlicensed band from a base station;
identifying the one or more guard bands configured in the unlicensed band based on the first configuration information;
identifying a plurality of resource block (RB) sets configured in the unlicensed band based on the one or more guard bands;
receiving, from the base station, second configuration information indicating whether downlink communication is performed in each of the plurality of RB sets; and
performing the downlink communication with the base station in a first RB set among the plurality of RB sets, the first RB set being indicated by the second configuration information as an RB set in which the downlink communication is performed,
wherein each of the one or more guard bands is located between adjacent two RB sets, resources of a channel state information-reference signal (CSI-RS) are configured in the plurality of RB sets, a measurement operation on the CSI-RS is performed in the downlink communication between the terminal and the base station in the first RB set, and the measurement operation on the CSI-RS is not performed in a second RB set among the plurality of RB sets when the second RB set is indicated by the second configuration information as an RB set in which the downlink communication is not performed.
