Method for measuring interference and user equipment for LTE-U
First Claim
1. A method for measuring interference in a user equipment using a licensed band and an unlicensed band through LTE-A (Long Term Evolution-Advanced) based carrier aggregation (CA), comprising:
- receiving configuration information on at least one or more resources for measuring interference in the unlicensed band from a base station;
measuring interference caused by Wireless Local Area Network (WLAN) at the at least one or more resources in the unlicensed band except for interference caused by LTE or the LTE-A; and
reporting the measured interference to the base station,wherein the configuration information includes information about a position of a specific subframe in a time domain.

Abstract
Provided in one embodiment of the present invention is a method for measuring interference with user equipment (UE) using a licensed band and an unlicensed band, through carrier aggregation (CA) according to long term evolution-advanced (LTE-A). The method comprises the steps of: receiving, from a base station, configuration on the position of a resource for measuring interference in the unlicensed band; measuring, from the position of the resource on the unlicensed band, interference from a wireless LAN (WLAN), excluding interference from the LTE-A; and reporting the measured interference to the base station.
