Method for reporting channel status information on license assisted access based cell

A user equipment (UE) for reporting channel status information (CSI) on a license assisted access (LAA) based cell, the UE comprising:

• a transceiver configured to receive a configuration of a CSI report;
• and
• a processor configured to consider that a periodic CSI report is not configured for the LAA based cell although the configuration of the CSI report is received,
• wherein if the LAA based cell is configured and if the number of CSI measuring processes is equal to or greater than a predetermined number Ny at a first subframe, the processor is configured to not update measurement for the CSI report at the first subframe.
