The UE receives, from a base station, a configuration specifying an initial aggregated bandwidth W0 carried on C0 component carriers on which a reception unit (RXU) of the UE is to receive signals. The UE determines a total bandwidth WTOT on which the UE is capable of receiving signals. The UE determines, based on WTOT and W0, an initial hardware limit of Q0? RXUs that the UE is allowed to activate concurrently. The UE determines an adjusted aggregated bandwidth W1 carried on C1 component carriers on which an RXU of the UE is to receive signals based on a channel condition between the UE and the base station.
