Abstract
Methods and apparatuses are provided for canceling interference at a User Equipment (UE) in a wireless communication system. A signal that includes a desired signal and an interference signal is received from at least one Base Station (BS). A random parameter is generated by projecting a vector of the received signal onto a set of projection vectors. A decision metric is determined using the random parameter. 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 is determined. The interference signal is canceled from the received signal using the TPR.
