SCHEME FOR INTERFERENCE CANCELLATION OF UE IN CELLULAR COMMUNICATION SYSTEM

摘要

The present invention relates to a method for canceling interference of a terminal in a cellular communications system. The method comprises the following steps of: receiving a signal that includes a desired signal and an interference signal from at least one base station; generating a random variable by projecting a vector of the received signal onto a set of M projection vectors to determine a traffic-to-pilot ratio (TPR) of the interference signal; determining a decision metric by using the random variable to determine the TPR of the interference signal; determining a TPR that minimizes the decision metric with respect to both a transmission mode candidate group of the interference signal and a TPR candidate group of the interference signal; and canceling the interference signal from the received signal by using the TPR.
