Dynamic allocation of carrier aggregation resources based on device requests

Examples disclosed herein provide systems, methods, and software to dynamically provide carrier aggregation to wireless communication devices. In one example, a method of operating an eNodeB includes exchanging first wireless communication signals with a wireless communication device using a first carrier aggregation configuration. The method further provides identifying a request from the wireless communication device for a modified quality of service, and determining a second carrier aggregation configuration based on the request. The method also includes exchanging second wireless communication signals with the wireless communication device using the second carrier aggregation configuration.
