Claim of US Patent No. 10,716,158

1. A method for a wireless communication system to configure service of a user equipment device (“UE”), wherein the system supports a first radio access technology (“RAT”) and a second RAT, including operation on carriers according to the first RAT (“first-RAT carriers”) and operation on one or more carriers according to the second RAT (“second-RAT carrier(s)”), the method comprising:serving, by the system, the UE with dual-connectivity on (i) a first-RAT carrier and (ii) a second-RAT carrier;
selecting, by the system, an additional first-RAT carrier to aggregate with the first-RAT carrier of the dual-connectivity service, wherein the UE is not yet served on the additional first-RAT carrier, and wherein the selecting includes (i) determining a level of load attributable to standalone first-RAT service on the additional first-RAT carrier, and (ii) selecting the additional first-RAT carrier based at least on the determined level of load attributable to standalone first-RAT service on the additional first-RAT carrier being predefined-threshold low; and
configuring, by the system, carrier-aggregation service of the UE on at least (i) the first-RAT carrier of the dual-connectivity service and (ii) the selected additional first-RAT carrier.
