Title:
METHOD FOR SUPPRESSING INTERFERENCE OF TERMINAL IN MULTIPLE INPUT MULTIPLE OUTPUT WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/141384
Kind Code:
A1
Abstract:
Disclosed is a method for enabling a terminal to process a signal in a wireless communication system. Specifically, the method for enabling a terminal to process a signal in the wireless communication system includes the steps of: estimating a recommended transmission beam-forming vector and a prior received filtering vector; calculating an effective channel for an adjacent cell by applying the prior received filtering vector to a signal received from the adjacent cell; estimating a constraint beam-forming vector for the adjacent cell on the basis of the effective channel; transmitting the information of the transmission beam-forming vector and the constraint beam-forming vector to the serving cell; receiving adaptive response signals of the transmission beam-forming vector and the constraint beam-forming vector; and receiving the signal to which the transmission beam-forming vector is applied, from the serving cell by applying the prior received filtering vector.
