Claim of US Patent No. 10,893,562

1. A method for a wireless communication system to allocate air-interface resources, wherein the system provides a coverage area on a first radio access technology (“RAT) and on a second RAT, including operating in the coverage area on a plurality of carriers according to the first RAT (“first-RAT carriers”) and operating in the coverage area on at least one carrier according to the second RAT (“second-RAT carrier”), the method comprising:determining, by the system, a capacity demand respectively of each of the first-RAT carriers in the coverage area; and
dynamically allocating, by the system, resources of the second-RAT carrier in the coverage area for use in dual-connectivity service of user equipment devices (UEs) served on individual ones of the first-RAT carriers, wherein the dynamic allocation is based on a comparison between the determined capacity demands respectively of the individual first-RAT carriers.
