Channel state information measurement method and user equipment
First 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, signaling information indicating that a base station occupies a carrier on an unlicensed band in at least one subframe, from the base station;
identifying, by the UE, at least one subframe 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 subframe, while excluding a measurement result of at least one subframe in which the base station does not occupy a carrier on the unlicensed band; and
transmitting the CQI report to the base station.

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 a user equipment (UE), resource indication information for a CSI measurement; performing, by the UE, the CSI measurement according to the resource indication information, and transmitting a Channel Quality Indicator (CQI) report to a control node. According to the present disclosure, users may be scheduled by the base station more effectively and the efficiency of the whole network may be increased.

8. A user equipment (UE) for transmitting a channel quality indicator (CQI) report, the UE comprising:
-
a transceiver configured to; receive configuration information indicating resources for a channel state information (CSI) measurement, and receive signaling information indicating that the base station occupies a carrier on an unlicensed band in at least one subframe; and a processor configured to; identify at least one subframe in which the base station occupies a carrier on the unlicensed band based on the signaling information, generate a CQI report based on measurement results at the at least one identified subframe, while excluding a measurement result of at least one subframe in which the base station does not occupy a carrier on the unlicensed band; and control the transceiver to transmit the CQI report to the base station. - View Dependent Claims (9, 10, 11, 12, 13, 14)
