Title:
APPARATUS AND METHOD FOR CANCELLING INTER-CELL INTERFERENCE IN COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/065087
Kind Code:
A1
Abstract:
The present disclosure relates to an apparatus and method for canceling and/or suppressing inter-cell interference in a wireless communication. The method includes: establishing a Radio Resource Control (RRC) connection with a base station through a first serving cell; receiving, at a User Equipment (UE), an RRC message through the first serving cell, the RRC message comprising cell-specific reference signal (CRS) information of a neighbor cell and Physical Downlink Shared Channel (PDSCH) information of the neighbor cell, and the PDSCH information of the neighbor cell comprising a parameter relating to a power ratio of a CRS of the neighbor cell and a PDSCH of the neighbor cell; receiving the PDSCH through the first serving cell; performing a channel estimation for retrieving data from a PDSCH of the first serving cell; and retrieving the data from the PDSCH of the first serving cell based on the second channel estimation.
