Abstract: Systems and techniques for interference management. A set of CSI-RS subframe configurations is established, and a mapping specified associating each CSI-RS subframe configuration with a corresponding CSI-RS configuration subset indicator, such that the CSI-RS configuration subset indicator identifies allowed CSI-RS subframe configurations at a first base station. The specified mapping is stored at the base station, and the configuration subset indicator is signaled to neighboring base stations. In response to receiving one or more CSI-RS configuration subset indicators at a user device from a serving base station, a determination is made for each of plurality of subframes whether one or more CSI-RS subframe configurations represented by the one or more CSI-RS configuration subset indicators indicates a CSI-RS presence in the subframe. If the one or more subframe configurations indicates a CSI-RS presence, at least partially clean resource element (RE) cancellation interference is applied in the subframe.
