Claim:
1. A method for canceling interference at a User Equipment (UE) in a wireless communication system, the method comprising: receiving a signal comprising a desired signal and an interference signal from at least one Base Station (BS) using a transceiver; generating a random parameter by projecting a vector of the received signal onto a set of projection vectors; determining a decision metric using the random parameter; determining a Traffic to Pilot Ratio (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 using the determined TPR, wherein the transmission mode candidate group of the interference signal comprises a first group comprising a Transmission Mode (TM) 2, a TM 3, and a TM 4 of a Long Term Evolution (LTE) system, a second group comprising a TM 6 having a Precoding Matrix Indicator (PMI)=0, a third group comprising a TM 6 having a PMI=1, a fourth group comprising a TM 6 having a PMI=2, and a fifth group having a TM 6 having a PMI=3.
