Abstract
In a wireless network comprising a plurality of carriers available for carrier aggregation transmissions between a base station and UE, the base station: (i) determines whether a requirement exists to transmit data between the UE and the base station via a carrier aggregation transmission; (ii) in response to determining that the carrier aggregation transmission requirement exists, selects a primary component carrier and one or more secondary component carriers from the plurality of carriers for the carrier aggregation transmission based on one or more of each carrier's group delay, group delay variation, or insertion loss; (iii) allocates the selected primary and secondary component carriers to the carrier aggregation transmission; (iv) informs the UE of the allocation; and (v) executes the carrier aggregation transmission according to the allocation.
