Title:
METHOD AND APPARATUS FOR TRANSRECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/012637
Kind Code:
A1
Abstract:
The present invention relates to a wireless communication system. A method for a terminal reporting channel state information (CSI) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving, from a second cell, which is a serving cell and neighboring a first cell, resource block allocation information related to downlink data of the second cell; selecting, based on the resource block allocation information, either a first interface measurement resource (IMR) in which interference from the second cell is present or a second IMR in which interference from the second cell is absent; and transmitting, to the first cell, a channel quality indicator (CQI) calculated based on the IMR which has been selected.
