A UE performs up to a threshold number of attempts to transmit a default capability message to a base station, the default capability message representing a default set of CA combinations supported by the UE. If transmission is unsuccessful, the UE switches to a compact capability mode in which the UE attempts to transmit compacted UE capability messages representing successively smaller subsets of the default set of CA combinations until either a capability message is successfully received by the base station or a second threshold number of unsuccessful transmission attempts is performed. To facilitate configuration of an initial compacted capability message, the UE maintains a PC list that lists one or more cells that have been identified previously as incapable of receiving default-sized capability messages and that further identifies a representation of a limited subset of CA combinations to include in capability messages sent to a corresponding listed cell.
