## Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments of the present disclosure provide a channel state information measurement method, including receiving, by the UE, configuration information indicating resources for a channel state information (CSI) measurement; receiving, by the UE, from a base station, signaling information indicating one or more resources in which the base station occupies a carrier on an unlicensed band; identifying, by the UE, at least one resource in which the base station occupies the carrier on the unlicensed band, based on the signaling information; generating a CQI report based on measurement results at the at least one identified resource, while excluding a measurement result of at least one resource in which the base station does not occupy a carrier on the unlicensed band; and transmitting the CQI report to the base station.

## Claims

### Claim 1

A method for transmitting a channel quality indicator (CQI) report by a user equipment (UE), the method comprising:
receiving, by the UE, configuration information indicating resources for a channel state information (CSI) measurement;
receiving, by the UE, from a base station, signaling information indicating one or more resources in which the base station occupies a carrier on an unlicensed band;
identifying, by the UE, at least one resource in which the base station occupies the carrier on the unlicensed band, based on the signaling information;
generating a CQI report based on measurement results at the at least one identified resource, while excluding a measurement result of at least one resource in which the base station does not occupy a carrier on the unlicensed band; and
transmitting the CQI report to the base station.
