Methods, systems, and devices for wireless communications manager are described. An example method for wireless communication at a UE includes receiving a request for a frequency band capability of the UE from a network, wherein the request includes a plurality of network frequency bands. The method may also include selecting a subset of frequency band combinations from a plurality of frequency band combinations supported by the UE, wherein a numerical quantity of the plurality of frequency band combinations supported by the UE exceeds a size constraint of a capability message, and wherein the subset includes at least one frequency band combination for each network frequency band. The method may also include sending the capability message in response to the request that includes an indication of the subset of frequency band combinations.
