Certain aspects of the present disclosure relate to methods and apparatus for coordinating UE capabilities across RATs. In some cases, a UE may provide an indication of one or more first sets of capabilities of the UE to operate in a first RAT network that are compatible with one or more second sets of capabilities of the UE to operate in a second RAT network. Indicating the sets of capabilities may require less signaling overhead than explicitly signaling all possible combinations of capabililites.
