Abstract
An adaptive interference cancellation method is disclosed. In an example, when a UE is served in a first cell by a first access node, the UE detects a second cell provided by a second access node that is not serving the UE. Further, responsive to the detecting, the UE determines that both (i) a broadcast CRS of the second cell occupies air-interface resource elements that the first access node uses as part of a PDSCH of the first cell and (ii) the UE has coverage strength of the second cell that is threshold similar to coverage strength that the UE has from the first access node. And, responsive to the determining, the UE cancels from scheduled PDSCH transmission from the first access node to the UE, potential interference attributable to the broadcast CRS of the detected second cell, such as by reconstructing and subtracting the CRS from the PDSCH transmission.
