We formulate the downlink cross-carrier resource allocation problem in LTE-Advanced carrier aggregation (CA) systems as an unbalanced transportation problem (TP). The component carriers (CC's), or their associated sub-bands, represent the supply points whereas the users requesting traffic represent the demand points. The cost of shipping from a supply point to a demand point is set as a function of...
