## Abstract

A wireless communication network controls wireless base stations that serve wireless relays that serve wireless User Equipment (UEs). In a relay control system, data transceivers receive configuration data that was transferred by the wireless relays and that indicates their individual wireless media services. Relay control circuitry allocates individual carrier aggregation Quality-of-Service (QoS) levels to the individual wireless relays based on the individual wireless media services. The relay transceivers transfer the individual carrier aggregation QoS levels for the individual wireless relays to the wireless base stations. The wireless base stations serve the wireless relays with the individual carrier aggregation QoS levels. The wireless relays serve the wireless UEs with the wireless media services.
