1. A method of controlling configuration of a relay, wherein the relay has a coverage footprint and provides service on a first air interface having a frequency bandwidth, and wherein the relay is served by a donor access node over a second air interface on which the donor access node provides service, the method comprising:
detecting that load on the second air interface on which the donor access node provides service is threshold high, wherein the second air interface on which the donor access node provides service comprises at least one carrier and defines air-interface resources for carrying communications, and wherein detecting that load on the second air interface is threshold high comprises detecting that at least a predetermined threshold high percentage of the air-interface resources are used per unit time; and
responsive to at least the detecting that the load on the second air interface on which the donor access node provides service is threshold high, causing the relay to perform at least one action comprising reducing the frequency bandwidth of the first air interface on which the relay provides service, wherein the relay continues to provide service after performing the at least one action.
