Title:
METHOD FOR MEASURING INTENSITY OF INTERFERENCE SIGNAL BASED ON CSI-RS IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/129863
Kind Code:
A1
Abstract:
Disclosed is a method for measuring the intensity of an interference signal by a terminal in a wireless communication system. More particularly, a method for measuring the intensity of an interference signal from a first base station by a terminal in a coordinated multipoint (CoMP) environment comprises: a step of receiving a plurality of channel status information-reference signals (CSI-RSs) from a second base station; a step of receiving downlink signals output from a plurality of resource element (RE) pairs corresponding to the respective plurality of CSI-RSs from the first base station; and a step of measuring a plurality of interference intensities based on the plurality of CSI-RSs and the received downlink signals.
