The method includes determining the number of tones to accumulate channel values among tones included in a resource area, based on a minimum delta cyclic shift (CS) that represents a minimum gap between CS values allocated to user equipments (UEs) and a number of UEs to be multiplexed, creating a matrix of amounts of change in phase for the tones to accumulate for the UEs to be multiplexed, and canceling MUI based on a signal matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for canceling multi-user interference in wireless communication system","description":"Disclosed is a method for canceling multi-user interference (MUI) by a base station (BS) in a wireless communication system.
