Title:
INTERFERENCE CANCELLATION METHOD IN WIRELESS COMMUNICATION SYSTEM, AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2016/021944
Kind Code:
A1
Abstract:
The present specification provides a method for receiving data through interference cancellation. The method can comprise the steps of: receiving a transmission signal transmitted by a DMRS-based transmission method; detecting, from the transmission signal, a DMRS-based transmission parameter for an interference cell having caused interference in the transmission signal; estimating an interference channel for the interference cell on the basis of the detected DMRS-based transmission parameter; generating an interference signal for the interference cell on the basis of the estimated interference channel; and cancelling the generated interference signal from the transmission signal so as to restore data transmitted by a serving cell.
