In one example embodiment, a method for identifying interfering physical channel configurations and cell-specific reference signals (CRSs) for the characterization of dynamic interferers includes constructing configuration indications. Each configuration indication may include a physical cell identity, antenna port information for a cell-specific reference signal (CRS), and an identification of a channel state information reference signal (CSI-RS). First and second configuration indications may be transmitted to a first wireless device. A first physical channel may be transmitted to the first wireless device. A second physical channel transmitted from a second network node may interfere with the first physical channel and be identifiable at least in part based on the first and second configuration indications. The first and second configuration indications may include a same physical cell identity and same antenna port information.
