Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing an interference mitigator are disclosed. In one aspect, a method includes the actions of determining, by a cellular base station, one or more first cell reference signal symbols of the cellular base station. The actions further include determining one or more second cell reference signal symbols of a neighboring cellular base station. The actions further include determining that a user equipment is communicating with the cellular base station. The actions further include providing, by the cellular base station and to the user equipment, the one or more first cell reference signal symbols and the one or more second cell reference signal symbols. The user equipment reduces interference by performing rate matching around the one or more first cell reference signal symbols and the one or more second cell reference signal symbols.
