Title:
METHOD AND USER EQUIPMENT FOR REPORTING CHANNEL STATE INFORMATION FOR UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2017/047988
Kind Code:
A1
Abstract:
One embodiment of the present invention provides a method for a user equipment (UE) reporting channel state information (CSI) for an unlicensed band. The method may comprise the steps of: measuring only a received signal strength indicator (RSSI) if, at a time point when a reference signal has to be received from a serving cell, the reference signal cannot be received because the unlicensed band is in a busy state; estimating a virtual CSI value on the basis of a comparison between the measured RSSI and a previously measured RSSI; and reporting the estimated virtual CSI value to the serving cell.
