摘要： This disclosure relates to techniques for estimating noise and interference in a wireless communication system in which neighbor and serving cell reference signals are colliding. A wireless device and a base station may establish a wireless communication link such that the base station acts as a serving cell to the wireless device. It may be determined that one or more neighboring cells have colliding reference signals with the serving cell. Neighbor load conditions may be determined. A neighbor reference signal interference cancellation policy may be selected based at least in part on the determined neighbor load conditions and the one or more neighboring cells having colliding reference signals with the serving cell.
