BLIND DETECTION METHOD FOR DETECTING PRESENCE OF INTERFERENCE DATA TRANSMISSION AND ESTIMATING INTERFERENCE TRAFFIC-TO-PILOT POWER RATIO

摘要

The present invention provides interference canceling techniques based on blindly detected NAICS interference parameters. The purpose of the present invention is to check out a blind detection method for estimating a TPR to be used by a base station (BS) which provides interference. Especially, estimating the TPR is suggested by joint-classifying interference transmission modes into a set of Grassmannian vectors wherein the interference transmission modes can be obtained through projections of a signal, in which information is received. In addition, the suggested TPR detection method can be operated as a blind estimator for detecting whether PDSCHs providing interference exist in a given RB pair. Link-level simulation results are provided to verify effects of the suggested interference detection algorithms and interference canceling techniques.
